Deflection control type ink jet recorder

[Detailed Description of the Invention]

From a nozzle, the present invention injects the ink which added vibration and performs Charge alternatively with a Charge electrode in the position which Injection, Inc. divides into ink particles, It is related especially with control of ink pressure about the ink-jet recording device which deflects Charge ink particles with a deflecting electrode, and makes them collide with the prescribed position of a recording form. In this kind of ink-jet record, the distance from an ink injection nozzle to a recording form is long in Comparative range, therefore it is ink pressure, Although the ink particles injected and particle-ized from the nozzle receive the operation of a Charge electric field and a deviation electric field, it is set up highly to draw the flight orbit stable to the recording form, and reach. The ink particles of predetermined particle diameter are generated regularly, and in this, in order to make it take a predetermined deviation orbit correctly, ink viscosity, ink pressure, oscillating pressure, load electrical quantity, a deviation electric field, etc. must be controlled stably and correctly. Unless Injection, Inc. suits correctly the timing divided into ink particles in impression of Charge voltage (pulse), ink particles are not Charge(ed) properly. then, the former -- record Charge control -- point Stand up and ink pressure -- and -- or the phase search which stabilizes ink viscosity uniformly and defines the impression timing of a Charge voltage pulse -- Line intermediary To have. In this phase search, the Charge detector circuit which makes a subject an amplifier, an integration machine, and a comparison machine is connected to a non-contact type or contact type Charge sensing electrode, the Charge voltage pulse of short width is impressed to a Charge electrode, and the phase to ink particle separation of a Charge voltage pulse is shifted one by one for every predetermined time. If a Charge detector circuit emits the signal which shows "Charge", the phase of the Charge voltage pulse at that time will be determined as a proper load potential phase. Since the amount of deviations is affected with the flight speed of ink particles, in one mode, detecting the flight speed of ink particles, and adjusting ink pressure so that it may become a prescribed speed is also performed. For example, the art of detecting ink speed to a U.S. Pat. No. 3600955 specification (the August, 1971 issue, Int.Cl.G01d 15/13) and JP,50-105733,A, and adjusting ink pressure to them is indicated. However, in the former, speed detection of the ink particles of a late speed has a limit, and also since a speed detector circuit is the composition of integrating with the flight time of many Charge ink particles, and judging the propriety of speed with an integral value, there is a problem that speed detection takes time. The electrostatic induction form electrode of two Along is arranged into an ink flight orbit as indicated by JP,50-105733,A, In the mode which calculates time after the 1st electrode detects Charge ink particles until the 2nd electrode detects Charge ink particles, Since accuracy deteriorates low and temporally in the detecting accuracy of an electrostatic induction form electrode, in order for there to be a problem in reliability and to raise accuracy, the distance from a nozzle to a gutter, i.e., ink particle flight distance, must be lengthened. The attachment accuracy of a sensing electrode is also required and composition becomes complicated. Although there are some which detect directly the speed of the Charge ink particles deflected with the sensing electrode provided in the home position, since this amount of deviations is indefinite, naturally it is difficult to make Charge ink particles collide with a sensing electrode correctly. The present invention is a deviation control ink-jet recording device which adjusts ink pressure so that the flight speed of Charge ink particles may be detected and it may become a predetermined value, and is Then, Speed detection of Charge ink particles is aimed at simplicity and being able to make it exact and quick and providing simplicity and the thing which can be adjusted correctly and quickly for ink pressure. To achieve the above objects, in the present invention, The ink pressure search signal generation means which connects to it the Charge detector circuit which produces the Charge detection signal which shows the potential change corresponding to the collision to the gutter of Charge ink particles for the gutter which captures not printing images ink particles, and generates; ink pressure search load telegraphic communication item, and it gives to the above-mentioned Charge voltage generating means as an electric conduction object, It has an ink pressure adjustment means to give the ink pressure indication signal which calculates time until the signal which shows the potential change corresponding to the collision to the gutter of Charge ink particles by making an ink pressure search load telegraphic communication item into the starting point appears, and makes a discrete value agree in a desired value to the pump energization circuit which energizes a pressurization pump. In order to control [ the desirable example of the present invention ] the level fluctuation of the Charge detection signal by the ink dirt of a conductive gutter, while connecting a Charge detector circuit to a conductive gutter via a shielded wire, Between apparatus grounds is connected with a shielded wire by a resistor, and the resistance between a conductive gutter and an apparatus ground is made smaller than the resistance in ink dirt conductivity ink. In order to make adjustment of ink pressure quick, as for an ink pressure adjustment means, the amendment corresponding to the difference of the discrete value acquired with the last ink pressure directions value and a desired value shall set the ink pressure indication signal of Worship to the last ink pressure directions value. According to this, it is completed as a desired value by the flight speed of ink particles geometric-progressive for every speed detection of 1 cycle. The outline of a machinery system of one example of the present invention is shown in Drawing 1. The ink of ink tub 13 in which it was equipped with ink cartridge 14 is attracted with pump 1, and is fed by accumulator 2. Pressure vibration is controlled with accumulator 2 and filter 3, and Pressurization, Inc. seen off in accumulator 2 results in ink injection A head 4. In ink injection A head 4, excitation energization of the Electrostrictive vibrator is carried out with a constant period and fixed amplitude, and pressure vibration of a constant period and fixed amplitude is added to the ink in A head. Although ink is injected from the nozzle of A head 4, this pressure vibration separates the injected ink into particles from a nozzle in the position advanced for a prescribed distance. This particle-ization is equivalent to pressure vibration added to Pressurization, Inc. in A head 4, and Injection, Inc. particle-izes at a rate of one ink particle per cycle of pressure vibration. When Injection, Inc. impresses Charge voltage between Charge electrode 5 and the ink of A head 4 according to the particle-ized timing, the particle-ized ink particles have an electric charge. Charge ink particles and non-Charge ink particles are formed by whether Charge voltage is impressed to electrode 5 according to particle-izing of ink. Although Charge ink particles are deflected in the electric field of deflecting electrode 6 and collided with recording form 7, non-Charge ink particles go straight on, collide with gutter 8, are attracted with pump 11 through filter 10, are blown by air A tank 12, and return to ink tub 13. Each mechanism element shown in Drawing 1 is energized to Drawing 2, and the composition of the electric system which moreover performs Charge record control is shown in it. Sine wave generating / amplification circuit 16 impresses excitation voltage to the Electrostrictive vibrator of ink injection A head 4. Load telegraphic communication item amplification circuit 17 impresses pulse-like Charge voltage to Charge electrode 5, and deflecting voltage generating circuit 18 impresses the high voltage of a fixed level to deflecting electrode 6. As for the conductive gutter, one end of the cable core of shielded wire 9 is connected to 8, and Charge detector circuit 19 is connected to the other end of the cable core. Electric energization of the pumps 1 and 11 is carried out with pump drivers 15 and 20, respectively. In order to Charge ink to predetermined timing in flight speed detection (ink pressure search) of ink particles in this example, In order to impress search pulse voltage to electrode 5 in the phase search which unites the center of a Charge voltage pulse with the separation phase of ink particles, and in order to impress the record Charge voltage from which a level differs gradually in printing record to electrode 5, Timing pulse generator 26 for ink pressure search, search load telegraphic communication item generator 25, and record load telegraphic communication item generator 24 are impressed to load telegraphic communication item amplification circuit 17 alternatively [ the signal of Provided intermediary cages and these generators ] at gate circuit 23. The operation timing of each part of an electric circuit element becomes settled based on two or more sorts of timing pulses which pulse generator 21 generates. Micro computer 22 performs energization and control of each part. Micro computers 22 and those connection are shown with the composition of pulse generator 21, gate circuit 23, record load telegraphic communication item generator 24, search load telegraphic communication item generator 25, and tongue ming pulse generator 26 in Drawing 3. Pulse generator 21 comprises a crystal oscillator, pulse generator 211 containing a Divide counter, and Divide counter 212. A pulse of eight sorts of 50% duties (3.2 MHz, 800 kHz, 400 kHz, 200 kHz, 100 kHz, 100 / 32= 3.125 kHz, 133 kHz, and 390 Hz) is generated. A 100-kHz pulse is impressed to sine wave generating / amplification circuit 16. Circuit 16 generates the sine wave of the fundamental frequency ingredient of an input pulse, amplifies this, and impresses it to the Electrostrictive vibrator of A head. Thereby, 100-kHz pressure vibration is added to the ink of A head 4, and it is 100x10.³Ink particles are formed at a rate of Pieces/sec, and it flies towards gutter 8 or recording form 7. That is, ink particles are generated on the frequency of 100 kHz. Record load telegraphic communication item generator 24 comprises Charge code generator 244 which becomes at shift register 242, data selector 243 and a counter and a decoder, and output gate of counter 241 1 / for 2-minute circumferences (T flip flop), and 8 A bit of serial In- parallel out. A 100-kHz pulse is inputted into counter 241, and counter 241 impresses a 50-kHz pulse to shift register 242 as input data. The shift clock of shift register 242 is an 800-kHz pulse. 8 sets of pulse outputs (CHP) of shift register 242 are shown in Drawing 5. These 8 sets of pulses are impressed to data selector 243. The output control code of 3 A bit is given to data selector 243, and this code directs a set of outputs of 8 sets of pulses. Since shift energization of the shift register 242 is carried out by an 800-kHz pulse, 8 sets of pulse a~h are the things of a same synchronization and the same duty which were delayed at a time for this order in 0.00125 msec of phases. What is specified by three bit codes given to data selector 243 is outputted to and gate 280~289 of gate circuit 23 from a data selector. Search load telegraphic communication item generator 25 comprises decoder 251 and data selector 252, and 100, 200, and 3 sets of 400-kHz pulses are impressed to decoder 251. Although an output of decoder 251 serves as 8-set a~h shown in Drawing 5 as SP by this, those pulse width is 0.00125msec. the order -- a part for pulse width -- that is, 0.00125 msec of phases have shifted at a time. The same control code as 3 A bit control code given to data selector 243 of record load telegraphic communication item generator 24 is also given to data selector 252, and outputs search load telegraphic communication item a~h as follows.

[Table]

The output pulse of data selector 252 is impressed to and gate 234 of gate circuit 23. Timing pulse generator 26 comprises two J-K flip flops 261,262, and gate 263, and inverter 264. A 100/32-kHz pulse is given to tongue ming pulse generator 26 as a clock pulse, and micro computer 22 gives 1 pulse of pulses "H" of 0.36msec width (width a little longer than 32 cycles which are 50 kHz) to every of one ink particle flight speed detection. The ON of tongue ming pulse generator 26 and an output signal are shown in Drawing 6. The output (R27) of and gate 263 of tongue ming pulse generator 26 is given to gate circuit 23. The composition of pump driver 15, Charge detector circuit 19, and ink pressure adjustment circuit 27 is shown in Drawing 4. Pump driver 15 receives pump drive indication signal P15 from micro computer 22, And and gate 151, the decoder which receive a 390-Hz pulse from pulse generator 21, 256 sorts of pulses from which it comprises a counter and an output gate, and frequency differs on the basis of 390 Hz are generated, and it comprises pulse frequency variable circuit 152 and amplifier 153 which output alternatively one specified by eight bit codes. Since pump 1 is a thing of the type which carries out the both-way drive of the plunger by solenoid, amplifier 153 impresses 24V pulse to solenoid synchronizing with the output pulse of circuit 152. Ink pressure adjustment circuit 27, Up counter 271, subtraction circuit 272, eight switches (8 A bits) 273 for an ink target speed setup, latch circuitry 277 that Latchch a subtraction output, zero crossing detector circuit 274, and and gate 275 -- and -- or it comprises gate 101,276,278. Charge detector circuit 19 comprises resistor 191, electric field effect form transistor (FET) 192, negative phase amplifier 193, highpass filter 194, half-wave rectifier 195, integration circuit 196, and comparison machine 197 which carry out the apparatus ground of the shielded wire 9. As for the resistance of resistor 191, between gutter 8 and ground filters 10 is made into the value in which a rope is smaller than the resistance between them at the time of intermediary To have, and about 100Kohm in ink. Although slight stray capacitance is between the cable core of shielded wire 9, and an apparatus ground, and the cable core of shielded wire 9 becomes minus potential in this example whenever the negative charges of the ink particles are carried out and Charge ink particles collide with gutter 8, when the ink particles which Charge(ed) collide with gutter 8 continuously by the self-constant of stray capacitance and resistor 191, while it is continuing, the potential of a cable core continues -- minus potential -- intermediary To have. Therefore, continuous plurality is Charge(ed), and if the plurality which the next follows carries out Charge control made into non-Charge, the potential pattern corresponding to the pattern of this Charge and non-Charge will appear in the gate of FET192. It is changed into current by FET192, reversal amplification is carried out with amplifier 193, and this potential pattern is removed by highpass filter 194 in a low frequency wave noise, and is given to zero detector circuit 274 and half-wave rectification circuit 195 of ink pressure adjustment circuit 27. Micro computers 22 are a centralized processing unit (processor), an I/O Port, ON RAM and ROM, and a general-purpose computer that comprises an appearance interface. Each element explained above is controlled. The whole control outline which a micro computer (a microcomputer is only called below) performs is shown in Drawing 7, The details of the ink pressure control which sets up ink pressure (discharge pressure of pump 1) to become the desired value which detected the flight speed of ink particles to Drawing 8, and with which it was set to it with switch 273 are shown. The whole control outline is explained first. If a power supply is switched on, microcomputer 22 will initialize ON and an output port and will set control each element as a safe state. In this, pump drivers 15 and 20 are also set as OFF, and, also in and gate 235, it is set as OFF for deflecting voltage generating circuit 18 at OFF. After completing initialization, first, microcomputer 22 carries out output Set of the drive instruction signal, and makes pump 11 pump driver 20 with a driving state, next it is as a high level "H" temporarily about initial Set indication signal SR, Counter 271 of ink pressure adjustment circuit 27 is reset, and Latchch (memory) is directed to latch circuitry 277. The standup from L to H of SR is answered, it is reset (count value clearance), latch circuitry 277 also answers the standup from L to H of SR, and counter 271 Latchch input data. Thereby, it is set to 00000000 which shows 0, the output of subtraction circuit 272 serves as a desired value code set up with switch 273, and the output of counter 271 is Set(ed) by latch circuitry 277. Latch circuitry 277 outputs this code as it is. The output code of latch circuitry 277 is decoded in pulse frequency variable circuit 152, and sets a kind of 256 sorts of pulses as an output in circuit 152. As mentioned below, the pulse outputted at this time is a thing of the highest frequency in a setup at that time of switch 273 among two or more sets of pulses in which an output is possible. Microcomputer 22 ranks next, carries out Set (it is Set to high level H about P15) of the drive of pump 1, and turns ON a preparation timer (program timer). Thereby, in pump driver 15, a 390-Hz pulse (P27) is given to circuit 152 from and gate 151, Pulse frequency variable circuit 152 outputs the thing of the highest frequency to amplifier 153 in a setup at that time of switch 273 among two or more sets of pulses in which an output is possible, and pump 1 operates at the rate of the highest among the driving speed planned in the setup at that time of switch 273. Microcomputer 22 reads the state of each part for a preparation timer carrying out Time Oba there, while waiting, waiting and, and it outputs condition data to higher rank apparatus or an operation board according to a state. If a Then preparation timer carries out Time Oba in the printing recordable state, each part will go into an ink pressure adjustment, and, subsequently will progress to record control through phase search. If record finishes, it will progress to the same stop processing as initialization. When it goes up to the pressure corresponding to [ to between Line intermediary To have / in the ink pressure after accumulator 2 / timer / preparation ] the working speed of pump 1 for a time check and a preparation timer carries out Time Oba, it is stable to a certain pressure. Drawing 8 is referred to. If progressing it to adjustment of ink pressure, microcomputer 22 makes signal SR high level H temporarily first, resets counter 271 of ink pressure adjustment circuit 271, energizes latch circuitry 277, and Set the output (desired value set up with switch 273) of subtraction circuit 272 at that time. It is although the desired value is already set to latch circuitry 277 by the 1st ink pressure adjustment from power turn-on ON, Since the desired value is not set to Latchch 277 after carrying out an ink pressure adjustment once (at the time [ For example, the pass "Wait term" =Yes of the flow of 7 figure. an ink pressure adjustment ] of Returned), if it goes into an ink pressure adjustment, a desired value will be set to latch circuitry 277 as mentioned above. And when a timer (program timer) is turned on next, the time check of predetermined time (time until pump drive speed is stabilized from a strange intermediary as for the ink pressure after an accumulator) is started and a timer carries out Time Oba, Microcomputer 22 outputs signal P26 (refer to the 6th figure) of quantity level H between 0.36msec to and gate 275 of J-K flip flop 261 of timing pulse generating circuit 26, and ink pressure adjustment circuit 27. flip flop 261 of tongue ming pulse generator 26 -- P26 -- high level H -- when 100 / 32= 3.125-kHz pulse impressed to clock pulse input edge CK is on low level L from an intermediary, it Set. it understands, if Drawing 6 is referred to -- as -- a pulse (100 / 32= 3.125 kHz) -- H from L -- since signal P26 will be returned to L by the time it is set to an intermediary and L As for flip flop 261, a 3.125-kHz pulse is reset by L once again at the time of Noodle, and flip flop 262 is Set(ed). thereby, output R27 of and gate 263 shows in Drawing 6 -- as -- signal P26 -- H -- it resembles a 3.125-kHz pulse, it synchronizes with it, and during the round term is set to high level H from an intermediary. 32 ink particles are generated during this high level H. Output R27 of and gate 263 (H) is given to gate 290~293 through gate 236 in gate circuit 23. Thereby, while 32 ink particles are generated exactly, code 0010011100 which directs a predetermined Charge level to D/A converter 232 is impressed. Therefore, while 32 ink particles are generated, D/A converter 232 impresses the voltage of a predetermined level to load telegraphic communication item amplification circuit 17 continuously. Thereby, the ink particles of 32 continuation Charge. Thus, counter 271 is reset between the times of Line intermediary To have, i.e., R27=H, in Charge at the standup time from L to H of R27, the count-up from 0 is started, and and gate 275 of ink pressure adjustment circuit 27 is opened (gate-on). On the other hand, after the Charge ink particles of 32 continuation fly, it collides with conductive gutter 8 continuously and the 1st thing of Charge ink particles collides, the potential of the cable core of shielded wire 9 rises, after all of 32 Charge ink particles collide with a negative direction including a fall, and shows approximately pulse-like change. Corresponding to this electrical change, the output of amplifier 193 changes in the shape of an approximately pulse for Masakata. Immediately after the output of amplifier 193 collided for Masakata and the ink particles of the 32 times of Ivy, i.e., the Charge(ed) continuation, collide with conductive gutter 8 in a Stand top, Since the output of zero crossing detector circuit 274 of ink pressure adjustment circuit 27 rises from L to H and and gate 275 is opened by P26=H, the output of gate 276 rises to H and the subtraction output at that time is Latchch(ed) by latch circuitry 277. Since counter 271 was reset by H at the time of Ivy and the Stand top has started the count of a C27, i.e., 133 kHz, pulse to it, R27 is Latchch data, From a desired value, the value (the amount of gaps from a desired value) which subtracted the count number (flight time of Charge ink particles) of a 133-kHz pulse after starting Charge of ink particles until Charge ink particles collide with conductive gutter 8 is shown. The output of the output of counter 271 of ink pressure adjustment circuit 27 at the time of the time [ 1st ] ink speed detection explained above and subtraction circuit 272, highpass filter 194 of Charge detector circuit 19, zero crossing detector circuit 274, and latch circuitry 277 is shown in Drawing 6. while Charge of ink particles is started (R27 changes to H), the value (digital value) which counter 271 starts count-up of clock pulse C27, and the count data shows increases in proportion to time progress, as shown in Drawing 6. As shown in Drawing 6, from target time value to set up by 273, the value (digital value) which the output data of Together subtraction circuit 272 shows to this is inversely proportional to time progress, and decreases. When the Charge(ed) ink particles began to collide with gutter 8, it begins to go up as the output of highpass filter 194 shows in Drawing 6 and it reaches a zero crossing disregard level, the output of zero crossing detector circuit 274 is reversed from L to H (Charge ink detection), as shown in Drawing 6. Time t1 after starting Charge of ink particles until the output of zero crossing detector circuit 274 is reversed from L to H in this way is time for ink particles to go straight on from Charge electrode 5 to gutter 8, and ink particle flight speed is in inverse proportion to this time t1. When the count data of counter 271 when the output of zero crossing detector circuit 274 is reversed from L to H shows time t1 and measures at this time, i.e., flight time t1, the output data (to-t1 is expressed) of subtraction circuit 272 is Latchch(ed) by latch circuitry 277. Since the flight speed of ink particles is high since ink pressure is large while driving pump 1 at the speed corresponding to desired value data, therefore count number t1 is small, by this time [ 1st ] ink speed detection, data to-t1 which Latchch(ed) to latch circuitry 277 shows the large value in comparison. Then, or output S27 of gate 278 is high level H. After microcomputer 22 carrying out Set (it is Set about P26=H) of the flip flop 261 as mentioned above, carrying out Charge Perilla frutescens (L.) Britton var. crispa (Thunb.) Decne. of the ink particles between 0.36msec, resetting flip flop 261 (it is Set about P26=L) and stopping Charge of ink particles, That is, after finishing Charge of the ink particles between 0.36msec of the 1st time, the level of output S27 of The which waits for time progress of 0.64msec, or gate 278 is checked. microcomputer 22 -- or the output of a gate progresses to the 2nd ink speed detection that it is H (there is no = flight speed of A foreigner which does not have flight time t1 of ink particles in desired value to in A foreigner in target speed). That is, when a timer (program timer) is turned on, the time check of predetermined time (time until pump drive speed is stabilized from a strange intermediary as for the ink pressure after an accumulator) is started and a timer carries out Time Oba, Microcomputer 22 outputs signal P26 of high level H of 0.36msec to and gate 275 of J-K flip flop 261 of timing pulse generating circuit 26, and ink pressure adjustment circuit 27. Since the output of latch circuitry 277 is value to-t1 which subtracted last count value t1 of counter 171 from desired value to in this state, Since pulse frequency variable circuit 152 gives the pulse of frequency low before corresponding to the subtraction value to-t1 to amplifier 153, it is driving at a speed lower than a front, the ink pressure of pump 1 is lower than a front, and the flight speed of ink particles is lower than a front. By the output of P26, like last time, timing pulse generator 26 generates signal R27, and it gives gate circuit 23 and ink pressure adjustment circuit 27. Thereby, continuation Charge of the ink particles of 32 continuation is started, and counter 271 is reset and a 133-kHz pulse count is started. That is, time [ 2nd ] measurement of ink particle flight time t2 is started. And immediately after Charge ink particles collide with conductive gutter 8, zero crossing detector circuit 274 outputs H, and latch circuitry 277 Latchch the subtraction value at that time, i.e., to-t2, at the standup time. t2 is larger than t1, and since it is lower than the time of ink pressure being the 1st time, by this time [ 2nd ] ink speed detection, Latchch data to-t2 shows a value smaller than previous value to-t1, and it shows 0 by it. the time of being what shows 0 -- or the output of gate 278 -- low level L (to=t2; ink flight time is equal to a desired value) -- that of intermediary To have -- microcomputer 22 -- the flight speed of ink -- a desired value -- it progresses to phase search as intermediary To have. When it is not 0, a time [ 2nd ] ink speed detection and the time [ 3rd ] same ink speed detection are started. It is Repeat about ink speed detection until it is the same as that of the following or the output of gate 278 is set to 0. Between this repetition, Latchch data to-t1 of latch circuitry 277, to-t2, and ...... decrease geometric-progressive, and it is completed as target speed by the flight speed of ink particles geometric-progressive. Since the gutter which captures not printing images ink particles is made into conductivity in the ink pressure adjustment explained above, the Charge detector circuit which produces the signal which shows the potential change corresponding to the collision of Charge ink particles is connected to this and flight of Charge ink particles is detected, A response is quick to arrival of Charge ink particles, and, moreover, detection is trustworthy. Therefore, the flight speed of ink particles can be set as a desired value quickly and certainly. Since it is only having one Charge ink particle sensing electrode and one Charge detector circuit, the composition of a machinery system and an electric system does not become complicated exceptionally. It is not necessary to lengthen ink particle flight distance from A head 4 to recording form 7. Since pump pressure is changed corresponding to the deviation of the flight speed of ink particles, and a desired value, time until adjustment of ink pressure, i.e., ink flight speed, is performed geometric-progressive and it sets to a desired value is short. Next, if phase search is explained, after ending an ink pressure adjustment, microcomputer 22 will set to 000 three bit codes given to data selectors 243 and 252, will make and gate 235 Open (gate-on), and will start a time check. Although data selector 243 outputs by this d of SP to whom data selector 252 shows a of CHP shown in Drawing 5 in Drawing 5, Since printing data is L (un-recording), the output gate of Charge code generator 244 is closed, and as for all the outputs (Charge level directions code) of all of Charge code generator 244, Then and gate 280~289 is closed by L (0000000000). However, since 100 / 32= 3.125-kHz pulse is impressed to it, and gate 234 is Repeat about this below in closed Into between the following 16 cycles (between generation of 32 ink particles) to Open with 16 cycles of 100 kHz in between (between generation of 32 ink particles). Thereby, it reaches and gate 234,235 or lets gate 236 pass, Or SP's d (Drawing 5) is intermittently impressed to condition that 32 continuation is given among pulses d of SP who shows in Drawing 5, and set the dormant period for 32 pieces to gate 290~293 next, and 32 continuation is given to it again. While SP's d is given as for 32 continuation, only during the period whose d of SP is H, 0010011100 is given to D/A converter 232 and D/A converter 232 confers the load telegraphic communication item of the level corresponding to 0010011100 upon load telegraphic communication item amplification circuit 17 at it. Thereby, it synchronizes with SP's d, and the next in which 32 continuation moreover appeared is the pattern that place the pause for 32 continuation and then 32 continuation appears, and a Charge voltage pulse is impressed to Charge electrode 5. These Charge voltage pulses do not Charge, unless it has Matched in it, although timing Charge [ Be consistent and ink particles ] to particle-ization of ink. When it Charge, ink particles fly by the Charge pattern that the Charge ink particles of 32 continuation follow the next following the next of the Charge ink particles of 32 continuation in the non-Charge ink particles of 32 continuation. It is right potential while the Charge ink particles of 32 continuation have collided with the outgoing end of highpass filter 194 of Charge detector circuit 19 at gutter 8 at this time, While the non-Charge ink particles of 32 continuation have collided with gutter 8, the signal abbreviated 100 / in a cycle of 32= 3.125 kHz of negative potential appears. It is rectified by half-wave rectifier 195 and integration circuit 196 is integrated with this signal. If integration voltage exceeds a preset value, the output of comparison machine 197 will be reversed from H to L. Three bit codes which will output microcomputer 22 to data selector 243,252 then if output P19 of comparison machine 197 is set to L from H, It considers that the proper Charge timing which gives proper Charge is brought about, and an output setup is carried out as it is at data selector 243,252, and he turns OFF and gate 235 and follows it to record control. After carrying out output Set of the three bit codes 000 at data selector 243,252, and making and gate 235 into Open (ON) and Set(ing) a timer like the above-mentioned before the timer carries out Time Oba, If output P19 of comparison machine 197 is not reversed from H to L, microcomputer 22 carries out output Set of the 3 A bit control code which becomes data selector 243,252 001 shortly, and Set a timer similarly. And it waits to set output P19 of comparison machine 197 to L from H. If 3 A bit control code 001 is Set(ed) to data selector 243,252, data selector 243 will output shortly b of signal CHP shown in Drawing 5, and data selector 252 will output signal SP's e. That is, data selectors 243 and 252 all output the pulse which was delayed in 1 / 800msec phase from the signal outputted last time. Thus, if the point which is behind in the phase of a signal is Removal(ed), operation of each part is the same as a thing when carrying out output Set of 000 to the above-mentioned data selector 243,252. And microcomputer 22 is, when output P19 of comparison machine 197 is set to L from H, He considers that the proper Charge timing which gives proper Charge for three bit codes currently then outputted to data selector 243,252 is brought about, and as it is, an output setup is carried out at data selector 243,252, and he turns OFF and gate 235 and follows it to record control. While output P19 of comparison machine 197 has been H, when a timer carries out Time Oba, microcomputer 22 carries out output Set of 010 shortly at data selector 243,252. Like the following, as long as output P19 of comparison machine 197 is H, whenever a timer carries out Time Oba of the microcomputer 22, it updates 3 A bit control code given to data selector 243,252. Signal SP's a~h which data selector 252 outputs as shown in Drawing 5, Since the pulse width part phase has shifted to Mutually in 1/800msec in pulse width, While having changed 3 A bit control code in 000~111, each of SP's a~h is alternatively given to and gate 234, While outputting either of the 3 A bit control codes to data selector 243,252, ink particles come to Charge, and output P19 of comparison machine 197 is set to L from H. microcomputer 22 ends phase search there and carries out an output setup of the 3 A bit control code currently outputted to data selector 243,252 as it is -- and gate 235 -- closed (OFF) -- it carries out and progresses to record control. In record control, microcomputer 22 is considered as as at OFF of and gate 235, and considers timing pulse generator 26 as as [ reset (R27=L) ]. Thereby, the output of gate circuit 23 or gate 236 is maintained by low level L during record control, and only the output of and gate 280~289 is impressed to D/A converter 232. Microcomputer 22 ranks next and directs generating of deflecting voltage in deflecting voltage generating circuit 18. Thereby, the predetermined fixed high voltage is added to a deflecting electrode. Thus, at the time of record control, the predetermined fixed high voltage (deflecting voltage) is impressed to a deflecting electrode, and deflecting voltage is not impressed to it in adjustment of ink pressure, Since ink particles will deviate and a flight course will tend to be subject to the part of Natsushisori, and the influence of the circumference for a long time in speed detection of the ink particles in adjustment of ink pressure, if deflecting voltage is impressed, It is for the gutter which detects Charge of ink particles in order to make a flight course into the shortest by considering ink particles as going straight to capture not printing images ink particles, and is because detection of ink particles will become impossible if the deviation of Then and ink particles is large. A reset signal is given to Charge code generator 244 just before sending out of the printing data of one character. If a reset signal is received, Charge code generator 244 will clear a count value, and will start the count-up from zero. A count pulse is a pulse which is 100 kHz which pulse generator 21 outputs. A count code is outputted to and gate 280~289, only when printing data is high level H (record directions), This is given to D/A converter 232 through and gate 280~289, while output CHP (what is specified by three bit codes given to Then and data selector 243,252 by any one of the a~h) of data selector 243 is high level H. Signal CHP which data selector 243 outputs, What carries out ink Charge by phase search, and checked signal SP (among a~h), Since it is the thing which made an approximately center H pulse section of what is specified as current data selector 243,252 by three bit codes by which an output setup is carried out and which has 8 times as much H pulse section as the H pulse section, Record Charge pulse voltage impressed to Charge electrode 5 is pulse width wide in comparison which reaches [ from ] immediately after dissociating, just before separating into ink particles. Ink particles are certainly Charge(ed) on a level corresponding to an output code of Charge code generator 244. While having flown between deflecting electrodes, Charge ink particles deflect only the quantity corresponding to the electric charge which it has, and collide with recording form 7. Non-Charge ink particles go straight on, collide with gutter 8, and are attracted by pump 11 through ground filter 10. As this example explained above, first, by an ink pressure adjustment, ink pressure is set up so that the flight speed of ink particles may become a desired value, the flight speed of ink is provided in a request value, and they are;, next phase search, The phase of a load telegraphic communication item is provided in the timing which Charge ink particles certainly, and; and record Charge are performed. Thus, since the flight speed of ink particles is set constant and Charge is defined certainly, printing record quality becomes very high. In an ink pressure adjustment and phase search, intercept deflecting voltage, it also makes Charge ink particles go straight on, is captured by a gutter, and, moreover, detects Charge of ink particles. Thus, since Charge ink particles are made to go straight on and ink speed is detected in adjustment of ink pressure, the flight course of speed detection ink particles serves as the shortest, and speed detection is stable and exact. In printing record, impress deflecting voltage to a deflecting electrode, and deflect Charge ink particles, they are made to go to a recording form, and non-Charge ink particles are captured by a gutter. Thus, since one conductive gutter is shared for three uses for capture of the object for detection of ink flight speed, the object for phase search, and the not printing images ink particles at the time of record printing, both the composition of the machinery system of an ink-jet recording device and an electric system becomes easy so that the above explanation may show. Nevertheless, both detection of ink flight speed and phase search are trustworthy, and are stabilized. Since the apparatus ground of the cable core of shielded wire 9 is carried out by resistor 191 in Charge detector circuit 19 although gutter 8 becomes dirty easily from the splash of ink which collides with it, Since the apparatus ground of the ink recovery way is carried out in the prescribed position (filter 10), Then is also sure for the resistance change by the ink dirt of a gutter. [ Charge ] It is although counter 271 is used as a Up counter and he is trying to subtract a count value from a desired value in the above-mentioned example in subtraction circuit 272, Subtraction circuit 272 is omitted, switch 273 is connected to the preset input edge of the preset down counter for counter 271 as a preset down counter, and it may be made to perform counter preset (loading) instead of counter reset. If it carries out like this, the composition of ink pressure adjustment circuit 27 will become easy. In addition to this, the ink-jet recording device of the present invention is Can be applied about various kinds of change. For example, Charge code generator 244, gate circuit 23, timing pulse generator 26, ink pressure adjustment circuit 27 grade, and if needed, one of the other elements or two or more may be put on microcomputer 22 or other micro computers, and they may be changed. Force means 1, 2, and 15 which pressurize ink particles by the present invention as mentioned above in order to make it inject from ink injection A head, Charge means 5 which Charge the ink particle alternatively according to an image signal inputted, In a deviation control ink-jet recording device which records ink particles which have deviation means 6 which is established downstream from the charge means and exerts a deviation electric field on the ink particle, and were deflected by the above-mentioned deviation means on a recording form, Capturing means 8, 9, and 18 which detect an electric charge of ink particles captured while Capture(ing) ink particles which have been arranged between the above-mentioned deviation means 6 and the above-mentioned recording form 7, and were not deflected by the deviation means 6, At the time of pressurization control to ink particles, a deviation electric field by the above-mentioned deviation means 6 is in an intercepted state, Time to a standup when the above-mentioned capturing means 8, 9, and 19 detect load electrical quantity from a standup when ink particles were Charge(ed) by the above-mentioned charge means 5 is measured, It has control means 22 which controls pressurization by the above-mentioned force means 1, 2, and 15 according to a comparison result with the target time beforehand set as the measured time. since [ therefore, ] Charge ink particles can be made to collide with a sensing electrode correctly -- speed detection of Charge ink particles -- simplicity -- it can be made exact and quick -- ink pressure -- simplicity -- it can adjust correctly and quickly.
