Gyi 17-222 fixed in parallel with the sprocket 221 via clutch 246 for an inversion on axis dll by the sprocket for a manuscript stand inversion which fixed 221 on axis of rotation fIII passes Gear 219 and rack 220. - (IJi A draft table 3 is made to move in the direction of a return) 223 is cleaner driving shaft Sprout fixed on axis of rotation d12, and the above-mentioned cleaner drive connecting fitting 224 is fixed in parallel with Sukket 223 on this axis dt2. 225 is the sprocket for a heat roller drive fixed on axis of rotation dB, It fixes in parallel with sprocket 225 on this axis d8, and passes Gyi 17-226, Power is transmitted to Gear 227 fixed on heat roller axis du, and it is the heat roller axis (sprocket 229 fixed in parallel with Gyi A7-227 on one for 1 s is connected with sprocket 231 and chain 247 which were fixed with Gear 230 on axis of rotation dfi.). Above-mentioned Gear 227,230 gears with Gyi %7-228,232 provided in each upper roller in one, and makes an upper roller rotate. It is Establishment free [ rotation ] near the motor MM (it is] sprocket 233 being an object for directional change roller chain 234). It is stretched via the above-mentioned sprockets 203 and 208210211212, 216*217.221.223, and 225 and 233, rotates towards a figure Nakaya seal, and transmits drive A ] to each above-mentioned sprocket. Pulley 235 fixed to the high speed side of driving shaft d of main motor MM is connected with the above-mentioned cleaner brush driving pulley 237 attached to axis of rotation dtl via directional change pulley 236 enabling free rotation by belt 238, and drives the pulley 237. As shown in Drawing 10, when unit replacement P1 is inserted in main part T of a device, for example, Photo conductor drum drive connecting shaft 100, development counter drive connecting shaft 104, and cleaner drive connecting shaft 101 which are projected at the rear front of unit P1 engage with photo conductor drum drive metal fittings 215 by the side of main part T, development counter drive connecting fitting 206, and cleaner drive connecting fitting 224, respectively, The driving force from main motor MM is transmitted to the mechanism in unit P1. d5, t, and m are electric system contact buttons in which the main part side carries out socket (illustration Scratches) Connection of the electric system in Unitsu]~ for an operation Scout reason. A Trust-C control circuit is explained also in Drawings 5 and 11 below. First, if Kaisei of the main switch MSW is carried out, pilot lamp PL1 and fixing device F will be in an energization state, but fixing device F-1. is connected to temperature selector TO in series at this time, and it is opened and closed by this temperature selector TC. If print switch SW is pushed now, while relay RL+ will be magnetized, Simultaneously, relay RL2 is magnetized, When also becomes it, self-maintenance is carried out [ self-maintenance is carried out by point of contact ISa, ] by contact 2S2 through point of contact 182, and main motor MM, eraser lamp E'L+, and high-pressure power supply HT energize. H dishes of above-mentioned high-pressure power supplies are this thing that moves aside and supplies electric power to each of charger 2 for Charge, and charge 1744 for transfer. While exposure lamp L lights up by contact IS4 of above-mentioned relay RL1 in this way, electromagnetic clutch 245 for manuscript stand normal rotation energizes by contact IS3, and manuscript stand 3 starts movement in the scanning direction. Feed clutch 244 is also simultaneously energized through IS3, and feeding of a decalcomania paper is started. And when the tip of the above-mentioned decalcomania paper pushes microswitch MSF on the passage of You, the above-mentioned feed clutch 244 is un-energizing, and suspends an operation. When the above-mentioned manuscript stand 3 moves and manuscript image projection is completed, manuscript stand 3 operates microswitch MS2 and revises this point of contact. Self-maintenance of above-mentioned relay RL1 is reset in connection with it, exposure lamp L goes out, contact IS3 changes, clutch 245 for manuscript stand normal rotation is de-energized by that cause, and, on the other hand, Clutch 246 for a manuscript stand inversion is magnetized. Therefore, manuscript stand 3 starts movement in the direction of a return. Eraser lamp EL2 is simultaneously turned on by contact IS1. At this time, charger 2 for Charge is in a state of ON still. since it drives via main motor MM, and the above-mentioned development business objects 9a and 9b also come out and are, development of an unnecessary part on photo conductor drum 1 is prevented, and can prevent load to unnecessary consumption of a toner and cleaner C for excessive toner removal. Then, the above-mentioned manuscript stand 3 operates return Look and microswitch MS1 to a regulation position, and makes relay RL3 energize. Therefore, the electric charge charged by the contact 3S2 is discharged, and this serves as a pulse signal and starts the operation of timer relay TR. It operates only at the time of an one-sheet copy, and the above-mentioned timer is set as time until the decalcomania paper of the maximum copying paper size is discharged to a tray (not shown). If timer relay TR severs the circuit of relay RL2 in a set period in this way, self-maintenance of this relay RL2 is canceled, main motor MM and electric discharge RumpEL1 and high-pressure power supply HT are un-energizing, and a copy device will finish - copy cycle and will be in a waiting state. Next, explanation of several multi-sheet continuation copy will work the portion surrounded by the figure middle point line as a number-of-sheets meter, At this time, switch CSW1 is the switch connected to print SW turned on and turned off and parallel by solenoid SOL1, and switch CSW2 is connected with the charge circuit of capacitors C1 and C2 with the rotation switch driven by solenoid SQL1. Now, supposing it sets number of sheets as N sheets, capacitor C2 will be charged by point-of-contact of relay RL3 3S3 during the round trip of manuscript stand 3, microswitch MS1 will close with the return of manuscript stand 3 after that, and it will discharge through point-of-contact of relay RL3 3S3, and will hold solenoid SQL1 for a definite period of time. under the present circumstances -- up to the point of contact at which rotation switch CSW2 takes a step forward simultaneously by supplying switch CSW1 and being in the same state as Kaisei of print switch SW (N-1) -- one by one -- move Topple -- the following copy cycle comes to be performed by things. Although the same Stepping as the following is repeated, since charge of capacitor C2 is not performed at the time of the last one sheet, there is no operation of future solenoid SOL1 and it ends a copy cycle. In order to copy by a manual paper feed, table 42 for cover and manual bypass is opened wide to the position of 5th [ The ] figure dotted line, the point of contact of microswitch MS3 for a manual bypass change is changed in connection with it, and the circuit of the above-mentioned print SW is separated. Paper feed roller 29 is driven by blowing and uniting middle Gear 239 with manual paper feed roller axis Gear 239' simultaneously (Drawing 9). As explained above, the above-mentioned unit replacement P and P1 can carry out a connection drive with the drive mechanism of main part T of a device easily, If needed, either unit P of a magnetic brush development method or unit P1 of a cascade development method is simply substituted for a main part, and they are exchanged, Since it is not only usable also as a magnetic brush development method, but it is substitutable in the copying machine of which method of a manuscript stand move method or a manuscript stand fixed method, it is the combination of the main part of a copy device, and an imaging unit, easy -- a copy device -- polyphasicity -- To have -- things are made and the development method which suits the desired end very efficiently according to the purpose of use can be adopted. In the present invention, a photo conductor drum, a developing means, and a cleaner way stage are incorporated in one inside to Unitsu 1. therefore, also in maintenance, repair, exchange of a consumable part, etc., it also cancels being able to use a unit for a new unit and exchange J To, only being able to use a main part of a device for Immediately, for example, and being unable to use a device during work of the above [ obtain / to conventional one ], but giving a user inconvenience, and is that of nonglutinous rice. Since the device and photo conductor by which proximity arrangement is carried out are constituted by the photo conductor in one like a developing means cleaner way stage, the accuracy of the whole copy device carries out Direction in the top for which a mutual position regulation member is not required, Since a manufacturer can collect the units which an assembly and control are very easy, and productivity is also good, and were used for large (6) production with Be fit for for a fixed time and reuse can also be measured by carrying out reproduction readjustment, it excels also in relation to [ of economical efficiency and saving resources ] a standpoint.
