The present invention relates to the examination transmitter for transmitting again the radio test signal which conveys an examination digital data signal. Radio communication equipments are a radio selective calling receiver and a transceiver, for example. The following explanation mainly explains a radio selective calling receiver.

[0002]

[Description of the Prior Art]

Generally an examination transmitter has a signal generator which generates an examination digital data signal. It is connected to a signal generator and a radio test signal transmission section transmits the radio test signal which conveys an examination digital data signal.

[0003]

Generally a radio selective calling receiver has a wireless processing section which processes a radio test signal to an examination digital data signal. A data processing part receives an examination digital data signal as an input digital data signal, and processes an input digital data signal to the processed data signal. A reporting part reports generating of a data signal which was connected to the data processing part, answered the data signal processed [ above-mentioned ], and was processed [ above-mentioned ].

[0004]

[Problem(s) to be Solved by the Invention]

When examining this radio selective calling receiver, an examination transmitter transmits the radio test signal which conveys an examination digital data signal to a radio selective calling receiver. When the radio selective calling receiver does not have a failure portion, a reporting part reports generating of a data signal processed [ above-mentioned ]. When the radio selective calling receiver has a failure portion, generating of a data signal processed [ above-mentioned ] is not reported. Thus, it is examined whether the radio selective calling receiver has a failure portion, and a radio selective calling receiver is judged. However, when it is judged that the radio selective calling receiver has a failure portion, it is difficult for a failure portion to specify the remaining portion which has a wireless processing section, a data processing part, and a reporting part.

[0005]

the hand which the radio selective calling receiver usually had ON and an OFF state, and was connected to the source of reference voltage (for example, ground voltage is generated) -- when it has an operational switch and this switch is changed into an OFF state by manual operation, there are some to which it is the generating voltage of the source of reference voltage, and information operation of a reporting part is forbidden. If information operation can be forbidden by the transmitted signal of an examination transmitter, the inspection of the automatic radio selective calling receiver by an examination transmitter will be attained, and an examination will become easy.

[0006]

So, the subject of the present invention has a failure portion in providing the radio communication equipment which can operate in combination with the examination transmitter which may be specified easily.

[0007]

Another subject of the present invention has a failure portion in providing a wireless processing section or the radio communication equipment which can remain and can judge a portion.

[0008]

Another subject of the present invention is an examination transmitter used in combination with radio communication equipment, and there is in providing the examination transmitter as which the failure portion of radio communication equipment is made to specify it easily.

[0009]

the hand that other subjects of the present invention forbid information operation -- it is in answering the transmitted signal of an examination transmitter in a state equivalent to the OFF state of an operational switch, and providing automatically the radio communication equipment which can be formed.

[0010]

the hand that the subject of further others of the present invention forbids information operation -- it is in providing the radio communication equipment which can be formed easily automatically about a state equivalent to the OFF state of an operational switch.

[0014]

[Example]

Next, the example of the present invention is described with reference to drawings.

[0015]

When Drawing 1 is referred to, a radio selection call system has other radio selective calling receivers (not shown) which have the same structure as base station 20, radio selective calling receiver 21 by one example of the present invention, and radio selective calling receiver 21, and carry out same operation. Base station 20 is for being shown by RCS and transmitting a Was done wireless-communications signal. Radio selective calling receiver 21 processes wireless-communications signal RCS so that it may become clear behind.

[0016]

Radio selective calling receiver 21 is used in combination with examination transmitter 22 for examining radio selective calling receiver 21. Examination transmitter 22 is usually possessed by the maintenance engineer specializing in [ of a radio selection call system ] maintenance service. Examination transmitter 22 is for transmitting the radio test signal shown by RTS.

[0017]

It moves to Drawing 2 and wireless-communications signal RCS is shown along with the top line, i.e., the 1st line. Wireless-communications signal RCS of illustration is the POGSAG code radio signal provided in CCIR advice 584. As for wireless-communications signal RCS, the frame structure has a plurality of same frames of each other. Each frame of wireless-communications signal RCS conveys 1st thru/or n-th subframe SF1~SFn that follows synchronized signal SYN and synchronized signal SYN continuously. Here, n is an integer greater than or equal to 2. Synchronized signal SYN has a bit of a predetermined number, and is specified by the bit of a predetermined pattern.

[0018]

Radio selective calling receiver 21 (Drawing 1) and other radio selective calling receivers of a radio selection call system have a mutually different call number, and are divided into the 1st thru/or the n-th group. The 1st thru/or the n-th group are assigned to the 1st of each frame thru/or the n-th subframe. If it assumes that radio selective calling receiver 21 belongs to the 1st group, base station 20 (Drawing 1) will transmit call number signal CN showing 1st radio selective calling receiver 21, and communication message signal CME addressed to radio selective calling receiver 21 using subframe SFof The 1st 1. Call number signal CN has a preselected number of bits. Communication message signal CME has other one preselected number of bits. Each of synchronized signal SYN, call number signal CN, and communication message signal CME consists of the BCH (Bose-Chaudhuri-Hocquenghem) code.

[0019]

The combination of synchronized signal SYN, call number signal CN, and communication message signal CME is called a communication digital data signal here. This communication digital data signal is conveyed by wireless-communications signal RCS.

[0020]

In Drawing 2, radio test signal RTS is shown along with the 2nd line. Call number signal CN with which radio test signal RTS expresses 1st radio selective calling receiver 21, Wireless-communications signal RCS and the frame structure are the same except examination message signal TMS showing an examination message using 1st thru/or n-th subframe SF1~SFn, and being transmitted, in order to examine radio selective calling receiver 21. Instead, call number signal CN and examination message signal TME use only frame SFof The 1st 1, and may be transmitted.

[0021]

The combination of synchronized signal SYN, call number signal CN, and examination message signal TME is called an examination digital data signal here. This examination digital data signal is conveyed by radio test signal RTS.

[0022]

With reference to Drawing 2, it returns to Drawing 1 succeedingly, and explains operation of radio selective calling receiver 21 in case radio selective calling receiver 21 is examined by examination transmitter 22. Under the present circumstances, a maintenance engineer makes radio test signal RTS transmit to examination transmitter 22 first.

[0023]

Radio test signal RTS is taken up by antenna 23, and is supplied to wireless section 24. Wireless section 24 changes radio test signal RTS into a baseband (that is, it got over) signal (namely, recovery). The 1st waveform shaping section 25 carries out waveform shaping of the signal to which it restored to the signal with which the digital waveform was operated orthopedically. The signal operated orthopedically has an examination digital data signal which consists of synchronized signal SYN, call number signal CN, and examination message signal TME.

[0024]

Thus, the combination of antenna 23, wireless section 24, and the 1st waveform shaping section 25 acts as a wireless processing section which processes radio test signal RTS to an examination digital data signal.

[0025]

Selecting part (selector) 26 is connected to the 1st waveform shaping section 25 and 2nd waveform shaping section 25. Selecting part 26 is made by the maintenance engineer as [ choose / the examination digital data signal made by the 1st waveform shaping section 25 / as a selected signal ] so that it may become behind clear.

[0026]

Decoder 28 receives the signal chosen [ above-mentioned ] as an input digital data signal, and in order to establish a bit synchronization and a frame synchronization, it detects synchronized signal SYN. If a bit synchronization and a frame synchronization are established, decoder 28 will collaborate with P-ROM(programmable Rade-only memory) 29 which has memorized beforehand the telephone number signal showing the telephone number assigned to radio selective calling receiver 21. That is, decoder 28 compares call number signal CN with a telephone number signal by bit correspondence.

[0027]

When coincidence between the bits of call number signal CN and a telephone number signal is detected, decoder 28 sends a speaker driving signal to speaker 30, and makes speaker 30 generate the ringing tone showing the call to radio selective calling receiver 21 for a predetermined period. Simultaneously, decoder 28 sends a display drive signal to indicator 31, and displays the examination message of examination message signal TMS on indicator 31 in visible. Indicator 31 is LCD (liquid crystal display), for example.

[0028]

Thus, decoder 28 collaborates with P-ROM29 and acts as a data processing part which receives an input digital data signal. A data processing part processes an input digital data signal to the processed data signal (namely, a speaker driving signal and examination message signal TME). The combination of speaker 30 and indicator 31 acts as a reporting part which performs information operation of generating of a data signal which was connected to the data processing part, answered the data signal processed [ above-mentioned ], and was processed [ above-mentioned ].

[0029]

If radio selective calling receiver 21 performs generating of ringing tone, and the display of an examination message while examination transmitter 22 has transmitted radio test signal RTS, a maintenance engineer will judge that radio selective calling receiver 21 does not have a failure portion.

[0030]

Although examination transmitter 22 has transmitted radio test signal RTS, when radio selective calling receiver 21 does not perform the display of an examination message in generating of ringing tone, either, a maintenance engineer judges that radio selective calling receiver 21 has a failure portion. In this case, a maintenance engineer makes optical test signal OTS transmit to examination transmitter 22 instead of radio test signal RTS, in order that a failure portion may judge whether it is the remaining portion that has a wireless processing section, a data processing part, and a reporting part.

[0031]

Optical test signal OTS conveys an examination digital data signal like radio test signal RTS. Optical test signal OTS is controlled or modulated by an examination digital data signal in detail that the light-and-darkness light showing logic "1" and "0" the level of an examination digital data signal should be formed.

[0032]

Photoelectrical mind conversion part 32 is changed into the signal which optical test signal OTS was changed, i.e., was modulated. It is connected to photoelectrical mind conversion part 32, and the 2nd waveform shaping section 27 changes the signal modulated [ above-mentioned ] into the signal with which the digital waveform equivalent to an examination digital data signal (namely, synchronized signal SYN, call number signal CN, and examination message signal TME) was operated orthopedically.

[0033]

Thus, the combination of photoelectrical mind conversion part 32 and the 2nd waveform shaping section 27 acts as an optical treating part which processes optical test signal OTS to an examination digital data signal.

[0034]

Selection machine 26 is formed by the maintenance engineer here so that the examination digital data signal outputted by the 2nd waveform shaping section 27 may be chosen as a signal chosen [ above-mentioned ], so that the back may become clear. As mentioned above, decoder 28 has received the signal chosen [ above-mentioned ] as an examination digital data signal.

[0035]

Thus, selection machine 26 is connected to a wireless processing section and an optical treating part, and a data processing part (28, 29), One of the examination digital data signals outputted by the wireless processing section and the optical treating part is chosen, and it acts as a selecting part which outputs above-mentioned of examination digital data signal outputted by wireless processing section and optical treating part one as the above-mentioned input digital data signal.

[0036]

If radio selective calling receiver 21 performs generating of ringing tone, and the display of an examination message while examination transmitter 22 has transmitted optical test signal OTS, a maintenance engineer will judge that a failure portion is a wireless processing section.

[0037]

Although examination transmitter 22 has transmitted optical test signal OTS, Radio selective calling receiver 21 is a maintenance engineer when generating of ringing tone does not perform the display of an examination message, either, It is checked using measuring instrument implements, such as a voltmeter and an oscilloscope, whether an examination digital data signal exists in the 1st connecting point between the 2nd waveform shaping section 27 and selection machine 26. Then, a maintenance engineer checks whether an examination digital data signal exists in the 2nd connecting point between selection machine 26 and decoder 28 using a measuring instrument implement. When a maintenance engineer checks that an examination digital data signal exists in the 1st and 2nd connecting points, a maintenance engineer judges that a failure portion is the remaining above-mentioned portion (namely, a data processing part and a reporting part).

[0038]

When radio selective calling receiver 21 does not have a failure portion, radio selective calling receiver 21 answers wireless-communications signal RCS, and operates like the case where radio test signal RTS is received. Under the present circumstances, when radio selective calling receiver 21 receives call number signal CN showing the call number assigned to radio selective calling receiver 21, speaker 30 generates ringing tone. Indicator 31 displays the communication message of communication message signal CME, when communication message signal CME following call number signal CN showing the call number by which radio selective calling receiver 21 was assigned to radio selective calling receiver 21 is received.

[0039]

I will pay my attention to examination transmitter 22. Examination transmitter 22 has encoder 33 which acts as a signal generator for generating an examination digital data signal with logic "1" and "0" level. Transistor switch 34 supplies an examination digital data signal alternatively to one of radio test signal generator 34 and photogen actuators 35 which drive photogen 36. Photogens 36 are LED (light-emmiting diode), a laser diode, etc., for example.

[0040]

If an examination digital data signal is received via transistor switch 34, radio test signal generator 34 will generate radio test signal RTS which conveys an examination digital data signal. Radio test signal RTS is transmitted via antenna 37.

[0041]

Thus, test signal generator 34 and antenna 37 act as a radio test signal generating part which transmits radio test signal RTS which conveys an examination digital data signal.

[0042]

Photogen actuator 35 outputs the ON which expresses ON and OFF, respectively/an OFF drive signal, when an examination digital data signal is received and an examination digital data signal has logic "1" and "0" level. Photogen 36 answers an ON/OFF drive signal, and emits for it light namely, transmits light-and-darkness light as optical test signal OTS which conveys an examination digital data signal.

[0043]

Thus, photogen actuator 35 and photogen 36 act as an optical test signal generating part which transmits optical test signal OTS which conveys an examination digital data signal. Transistor switch 34 acts as a signal generator (namely, encoder 33), a radio test signal generating part, and a selection feed section connected to the optical test signal generating part. This selection feed section supplies an examination digital data signal to one of a radio test signal generating part and the optical test signal generating parts.

[0044]

When Drawing 3 is referred to, the radio selective calling receiver by the 2nd example of the present invention has the same portion shown with the same reference number as Drawing 1. It was connected to decoder 28, for example, this radio selective calling receiver has illumination part 39 which consists of Ramps. Illumination part 39 irradiates with indicator 31 by the illumination light, when illumination part 39 drives by decoder 28.

[0045]

Selection machine 26 has positive and a negative terminal, and switch 40 it has. Positive and a negative terminal are directly connected to the ground via resistance 41, respectively in the source of voltage. The source of voltage is shown by +V and gives right voltage to the above-mentioned positive terminal. Right voltage and ground voltage shall be equivalent to logic "1" and logic "0" level.

[0046]

The Maintenance engineer usually changes switch 40 into the OFF state. Namely, when radio test signal RTS is transmitted by radio transmitter 22 (Drawing 2), it changes switch 40 into the OFF state. When optical test signal OTS is transmitted by radio transmitter 22, a Maintenance engineer changes switch 40 into an ON state.

[0047]

Operation of selection machine 26 when changing switch 40 into the OFF state here is explained. In this case, 1st and circuit 42 has taken the logic "1" level via resistance 41. Since inverter 43 takes logic "1" level via resistance 41 and logic "1" level is reversed on logic "0" level, 2nd and circuit 44 takes logic "0" level. As a result, 1st and circuit 42 gives the examination digital data signal outputted to the Orr circuit 45 by the 1st waveform shaping section 25. The Orr circuit 45 gives the examination digital data signal outputted to decoder 28 by the 1st waveform shaping section 25.

[0048]

3rd and circuit 46 takes logic "1" level via resistance 41. Since inverter 47 takes logic "1" level via resistance 41 and logic "1" level is reversed on logic "0" level, 4th and circuit 48 takes logic "0" level. As a result, 4th and circuit 43 outputs the output signal of the 2nd waveform shaping section 27 to decoder 28.

[0049]

I will pay my attention to photoelectrical mind conversion part 32. Photoelectrical mind conversion part 32 has photo-transistor 50 which has a collector and the emitter connected to the ground. The collector is connected to source of voltage +V via resistance 51.

[0050]

Photo-transistor 50 receives the environment light of this radio selective calling receiver, when having transmitted radio test signal RTS without examination transmitter 22 transmitting optical test signal OTS. When environment light has high luminous intensity or brightness, the collector voltage of the collector of photo-transistor 50 becomes almost equal to ground voltage. When environment light has low luminous intensity or brightness, collector voltage becomes almost equal to the right voltage of source of voltage +V. Thus, collector voltage changes according to the luminous intensity of environment light. Photoelectrical mind conversion part 32 supplies collector voltage to the 2nd waveform shaping section 27 as a signal changed [ above-mentioned ].

[0051]

The 2nd waveform shaping section 27 operates orthopedically the signal changed [ above-mentioned ] to the signal with which the digital waveform was operated orthopedically. The signal operated orthopedically has logic "0" level, when it has logic "1" level when environment light has low luminous intensity, and environment light has high luminous intensity. That is, when the environment of this radio selective calling receiver is dark, the signal operated orthopedically has logic "1" level.

[0052]

As mentioned above, 3rd and circuit 46 of selection machine 26 outputs the signal (output signal of the 2nd waveform shaping section 27) operated orthopedically to decoder 28, when switch 40 is in an OFF state. Under the conditions that decoder 28 received the signal with which the logic "1" level was operated orthopedically when indicator 31 was driven so decoder 28 may have an examination message displayed by indicator 31, decoder 28 drives illumination part 39 so that it may make illumination part 39 irradiate with indicator 31 by the illumination light.

[0053]

Next, operation of selection machine 26 when changing switch 40 into the ON state is explained. As mentioned above, when optical test signal OTS which conveys an examination digital data signal is transmitted by examination transmitter 22, it changes switch 40 into an ON state. In this case, photo-transistor 50 receives optical test signal OTS from environment light rather, and processes optical test signal OTS to the signal changed or modulated like the case where photo-transistor 50 receives environment light. The 2nd waveform shaping section 27 operates orthopedically the signal changed [ above-mentioned ] to an examination digital data signal.

[0054]

When changing switch 40 into the ON state, ground voltage (logic "0" level) is supplied to inverters 47 and 43 via switch 40. Since inverters 47 and 43 supply logic "1" level to 4th and 2nd and circuits 48 and 44, an examination digital data signal is outputted to decoder 28 as an input digital data signal via the 4th and 2nd and circuits 48 and 44 and Orr circuits 45. Since ground voltage (logic "0" level) is supplied to 3rd and 1st and circuits 46 and 42, the output signal of the 2nd and 1st waveform shaping sections 27 and 25 is not supplied to decoder 28 via 3rd and 1st and circuits 46 and 42.

[0055]

With reference to Drawing 4, transistor switch 52 is used instead of switch 40 of Drawing 3. Transistor switch 52 has a base electrode, a collector electrode, and the emitter electrode connected to the ground. The collector electrode is connected to resistance 41, inverters 43 and 47, and 3rd and circuit 46 like the right terminal of switch 40.

[0056]

In order to change transistor switch 52 into one state of OFF and the ON states, logic circuit 53 is connected to the base electrode of transistor switch 52. Logic circuit 53 is connected to the output of the 2nd waveform shaping section 27 again. When a maintenance engineer wants to change transistor switch 52 into an OFF state, a maintenance engineer makes a lightwave signal generator (not shown) irradiate with the 1st lightwave signal toward photo-transistor 50 under the dark environment where a radio selective calling receiver is intercepted. The 1st lightwave signal conveys an OFF signal with the 1st predetermined pattern. When a maintenance engineer wants to change transistor switch 52 into an ON state, a maintenance engineer makes a lightwave signal generator irradiate with the 2nd lightwave signal toward photo-transistor 50 under the above-mentioned dark environment. The 2nd lightwave signal conveys an ON signal with the 2nd different predetermined pattern from the 1st predetermined pattern. The 1st and 2nd lightwave signals may be transmitted by an examination transmitter (Drawing 1).

[0057]

Reference of Drawing 5 shows the 1st lightwave signal along with the 1st, i.e., a top line, by OFFSIG. The 1st lightwave signal has the 1st portion shown by (a). The 1st portion (a) is a dark portion which continues for T seconds. The 2nd portion follows the 1st portion (a) and is shown by (b). In the 2nd portion (b), Ming and a dark portion appear by turns with the 1st cycle.

[0058]

The 2nd lightwave signal is shown by ONSIG along with the 2nd line. The 2nd lightwave signal is shown by (c) and has a precedence portion substantially equivalent to the 1st portion of the 1st lightwave signal. A succession portion is shown by (d) and follows a precedence portion (c). In a succession portion (d), Ming and a dark portion appear by turns the 2nd different cycle from the 1st cycle.

[0059]

It returns to Drawing 4 and is the combination of photo-transistor 50, resistance 51, and the 2nd waveform shaping section 27, When photo-transistor 50 receives the 1st lightwave signal, and when photo-transistor 50 receives the 2nd lightwave signal, the 1st and 2nd lightwave signals are processed to electric wave-like OFF and an ON signal, respectively.

[0060]

When logic circuit 53 receives an OFF signal, logic circuit 53 outputs continuously logic "0" (getting it blocked ground voltage), i.e., a low level, until logic circuit 53 receives an ON signal. If a low level is supplied to transistor switch 52, it will be in an OFF state. Transistor switch 52 will be in an OFF state, if an ON signal is received. When logic circuit 53 receives an ON signal, logic circuit 53 outputs logic "1", i.e., a high level, continuously until logic circuit 53 receives an OFF signal.

[0061]

If Drawing 6 is referred to, the radio selective calling receiver by the 3rd example of the present invention is shown, and the same reference number is given to the same portion. The radio selective calling receiver is provided with electric power switch 55 with an ON state and an OFF state. Electric power switch 55 is connected to battery 56 as a power supply. When electric power switch 55 is in an ON state, electric power is supplied to each part of a radio selective calling receiver from battery 56.

[0062]

Electric power switch 55 is in an ON state, and it explains the case where voltage is supplied to each part of a radio selective calling receiver. A radio selective calling receiver shall receive radio test signal RTS (Drawing 2). In this case, decoder 28 detects coincidence between the bits of call number signal CN of an examination digital data signal, and a telephone number signal. If decoder 28 detects coincidence, decoder 28 will generate the coincidence signal showing this coincidence. Next, decoder 28 generates examination message signal TME following call number signal CN of an examination digital data signal.

[0063]

the 1st switch 57 -- a hand -- it is operational and has an ON state and an OFF state. The 1st switch 57 is grounded as connection with the source of reference voltage.

[0064]

the 2nd switch 58 -- a hand -- it is operational and has an ON state and an OFF state. The 2nd switch 58 is grounded.

[0065]

Control part 59 is connected to storage part 60 which used decoder 28 and the 1st and 2nd switches 57 and 58, for example, RAM, (random access memory). When the 1st switch 57 changes into an OFF state and control part 59 receives a coincidence signal, control part 59 sends a speaker driving signal to speaker 30 via speaker driving part 61, and makes speaker 30 generate ringing tone. When the 1st switch 57 changes into an ON state and control part 59 receives a coincidence signal, control part 59 cannot send out a speaker driving signal to a speaker, but forbids generating of ringing tone.

[0066]

If a coincidence signal is received, control part 59 saves examination message signal TME following call number signal CN at storage part 60. When the 2nd switch 58 changes into an OFF state and control part 59 receives examination message signal TME, control part 59 sends examination message signal TME to indicator 31 via display driving part 62, and displays an examination message on indicator 31. When the 2nd switch 58 changes into an ON state and control part 59 receives examination message signal TME, control part 59 cannot send out examination message signal TME to indicator 31, but forbids the display of a communication message.

[0067]

These control parts 59, storage part 60, speaker driving part 61, and the control part that consists of combination of display driving part 62 are connected to a data processing part (that is, put together as decoder 28 and P-ROM29), and the 1st and 2nd switches 57 and 58. A control part controls a reporting part (that is, put together as speaker 30 and indicator 31), and when the 1st switch 57 (or the 2nd switch 58) changes into an OFF state, it permits information operation. When the 1st switch 57 (or the 2nd switch 58) changes into an ON state, a control part controls a reporting part and forbids information operation.

[0068]

1st transistor switch 63 is provided with a base electrode (namely, control terminal), has ON and an OFF state, and is connected to the 1st switch 57 in parallel. When predetermined control voltage is supplied to a base electrode, control of 1st transistor switch 63 is enabled into an ON state. Predetermined control voltage is substantially equivalent to a logical level "1."

[0069]

It is connected in parallel with the 2nd switch 58, and 2nd transistor switch 64 is the same in 1st transistor switch 58, structure, and operation. Each of 1st and 2nd transistor switches 63 and 64 is electrically mentioned as a controllable switch.

[0070]

The optical control signal which conveys the digital control signal transmitted by examination transmitter 22 (Drawing 2) is supplied to an optical processing portion (that is, put together as photoelectric converter 32 and 2nd waveform-shaping machine 27). An optical processing portion processes an optical control signal to a digital control signal.

[0071]

Decoder 65 is connected to 2nd waveform-shaping machine 27 via switch circuit 66 mentioned below. Switch circuit 66 supplies a digital control signal to decoder 65 so that it may become clear later on. Decoder 65 restores to a digital control signal to the recovery signal of a logical level "1", and supplies this recovery signal to at least one control terminal in 1st and 2nd transistor switches 63 and 64. At least one of these 1st and 2nd transistor switches 63 and 64 is determined by the digital control signal.

[0072]

Thus, decoder 65 functions as a control signal processing section connected to an optical treating part and a control terminal. A control signal processing section processes a digital control signal on predetermined voltage (namely, logical level "1"), and supplies predetermined voltage to a control terminal.

[0073]

The test method for examining the radio selective calling receiver shown in Drawing 6 with reference to Drawing 6 and Drawing 7 is explained. A maintenance technician changes electric power switch 55 into an ON state when examining a radio selective calling receiver. If electric power switch 55 will be in an ON state, the voltage from battery 56 will be supplied to each part of a radio selective calling receiver. If electric power switch 55 will be in an ON state, a trigger signal will be generated from the differential circuit which has capacitor 67 and register 68. In response to a trigger signal, control part 59 supplies a switch order signal to switch circuit 66 continuously. If a switch order signal is supplied, switch circuit 66 will connect the output of 2nd waveform-shaping machine 27 to the input of decoder 65, and will hold this connected state during reception of a switch order signal.

[0074]

A maintenance technician sends out the optical start signal which conveys the start signal of a digital test to examination transmitter 22. An optical treating part (that is, put together as photoelectric converter 32 and 2nd waveform-shaping machine 27) processes an optical start signal to the start signal of a digital test. If decoder 65 receives the start signal of a digital test via switch circuit 66, decoder 65 restores to the start signal of a digital test to the start signal of test, and sends out this start signal of test to control part 59. If control part 59 receives the start signal of test in predetermined time after control part 59 receives a trigger signal, control part 59 will supply a switch order signal continuously until control part 59 receives the end signal of test. Decoder 65 recovery of the end signal of a digital test will generate the end signal of test by decoder 65. The end signal of a digital test is conveyed by the optical end signal transmitted by an examination transmitter.

[0075]

When control part 59 does not receive the start signal of test in predetermined time, if a switch order signal is not supplied to switch circuit 66 where control part 59 stops supply of a switch order signal, switch circuit 66 will connect the output of 2nd waveform-shaping machine 27 to the input of control part 59.

[0076]

When switch circuit 66 connects the output of 2nd waveform-shaping machine 27 to the input of decoder 65, a maintenance technician makes radio test signal RTS which conveys an examination digital data signal transmit to another examination transmitter (not shown). Next, a maintenance technician makes the optical control signal which conveys a digital control signal transmit to examination transmitter 22.

[0077]

In Drawing 7, television camera 69 functions as an imaging device which picturizes the display picture of indicator 31, and generates the image signal showing a display picture. It is connected to television camera 69 and image processing portion 70 processes an image signal. Ringing tone is changed into an electric audio signal with microphone 71. Voice processing part 72 is connected to microphone 71, and an audio signal is processed.

[0078]

If it returns to Drawing 6 and switch circuit 66 connects the output of 2nd waveform-shaping machine 27 to the input of control part 59, photoelectric converter 32 will change environment light into an electric signal. 2nd waveform-shaping machine 27 operates an electric signal orthopedically to the shaping signal of a digital type. A shaping signal is sent out to control part 59 via switch circuit 66. Control part 59 drives illumination part 39 via lighting actuator 73 like decoder 28 of Drawing 3.

[0079]

As mentioned above, although the present invention was explained using the example, if it is a person skilled in the art, it cannot be overemphasized that various modification can be easily added to the present invention. For example, when control part 59 receives a coincidence signal in the state of ON in the 1st switch 57, it may be made for control part 59 to send out a speaker driving signal to speaker 30 in Drawing 6. In Drawing 6, a microphone may be used instead of photoelectric conversion circuit 32. In this case, in order to change transmitter switch 63 into an OFF state, an examination transmitter sends out the audio signal of predetermined frequency instead of an optical control signal.

[0080]

[Effect of the Invention]

As explained above, according to the present invention, not only a radio test signal but an optical test signal is answered, and the radio communication equipment examined is obtained. As for the radio communication equipment of the present invention, a failure portion may be easily specified in a wireless processing section or the remaining portion.

[0081]

According to the present invention, the examination transmitter which enabled transmission not only of a radio test signal but an optical test signal and as which the failure portion of radio communication equipment is made to specify it easily is obtained.

[0082]

the hand of forbidding information operation according to the present invention, in a state equivalent to the OFF state of an operational switch, answer the transmitted signal of an examination transmitter and the radio communication equipment which can be formed is obtained automatically -- the time of an examination -- a hand -- it becomes unnecessary to change an operational switch into an OFF state by manual operation
