- Reference numeral 5 3 is an amplifier for amplifying the motor ON / OFF signal output from the microcomputer 4 9.
- the output of the amplifier 53 is input to the gate of the MOSFET S of the motor power control unit 28.
- the MOSFET is between the battery 2 7 and the motor 2 2 and functions as a switch to turn on / off the voltage of the motor 2 2. Therefore, when the motor ON signal from the microcomputer 49 turns on the MOSFET and the voltage is applied to the motor 22, power is supplied from the battery 27, and the motor 22 is rotationally driven. Further, when the motor OFF is turned OFF in response to the motor OFF signal from the microcomputer 49, the electric power from the battery 17 is shut off and the motor 22 stops its rotation.
- a reduction gear 24 is combined with an output shaft of the motor 22 so as to rotationally drive the sector 1 gear 25.
- FIG. 9 shows a first embodiment of control, and is a flow chart for controlling one-shot operation.

- the watchdog timer WDT When the microcomputer 49 is operating normally, the watchdog timer WDT is reset periodically and thus the watchdog timer WDT is erroneous. If one signal is not output, but the microcomputer 4 9 malfunctions, the periodic watchdog timer WDT is not reset and the error signal is output to activate the safety device. It is for stopping.
- the timer value of the watchdog timer WDT is set as, for example, 10.sup.0 O ms at the initial stage when the microcomputer 49 is powered on. The description of the watch dog timer is omitted here, as it is a known technique.
- step 1 0 3 If it is detected that the trigger switch 3 7 is pressed in step 1 0 1, it is checked in step 1 0 3 whether or not the magazine 4 has a drop 1 9. This is carried out by inputting the signal of the bullet detection switch 4 1 to the microcomputer 4 9 and checking whether this signal is ON or OFF. When Kamakura 4 has bullets 19, the bullet detection switch 4 1 is pressed upward by the bullet pressing switch 4 2 and the bullet detection switch 4 1 is turned off.
- step 1 0 4 the procedure proceeds to step 1 0 4 and the power of the motor 2 2 is turned off.
- the microcomputer 49 outputs a motor OFF signal to the signal amplifier 53, and the amplifier 53 amplifies the signal and sends it to the motor power control unit 28.
- the motor power control unit 28 receiving this signal shuts off the power supplied from the battery 27 to the motor 22 with a switch.
- the switch used for the motor power control unit 28 can use a semiconductor switch. Although a bipolar transistor can be used as a semiconductor switch, it is preferable to use M O S -F E T for power saving. By using M o S-F E T (M o S field effect transistor), the life of the battery 27 can be extended.
- step 1 0 5 go to step 1 0 5 and after step 2 0 ms wait step 1 0 Return to 1.
- This waiting time is provided to stabilize the control, and is not limited to 20 ms.
- step 1 0 6 If it is detected in step 1 0 3 that the magazine 4 has bullets 1 9, the process proceeds to step 1 0 6 and the motor power is turned ON.
- the microcomputer 49 outputs a motor power ON signal to the signal amplifier 53, and the amplifier 53 amplifies the signal and sends it to the motor power control unit 28.

- the light passes through the rotation reference position detection hole 40 of the sector 1 gear 25, the light is received by the phototransistor 4 4, this signal is amplified by the operational amplifier 54, and is input to the microcomputer 4 9. Detected by When the photosensor is not at the position of the rotation reference position detection hole 40, the phototransistor 44 does not receive this light, so the rotation reference position detection signal is not inputted to the microcomputer 49.
- the rotation position is as shown in Fig. 6 (d) or 6 (a) before the sector 1 gear 25 engages with the rack 18 and the photo sensor rotates. Since the reference position detection hole 40 is not located, the rotation reference position of sector 1 gear 25 is not detected. If the rotation reference position of the sector 1 gear 25 is not detected, return to step 1 06 and repeat steps 1 0 6 and step 1 0 7 until the rotation reference position of the sector 1 gear 2 5 is detected. When the rotation reference position of sector 1 gear 25 is detected in step 107, the processing proceeds to step 108 to output a signal to turn off the motor power. At this time, the rotation reference position detection hole 40 of the sector 1 gear 25 is at the position of the photosensor as shown in FIG. 6 (c).

Upon receiving this signal, the motor power control unit 28 shuts off the power supplied from the battery 27 to the motor 22 with power control.
- the motor 22 whose power is cut off does not stop immediately but rotates to a certain extent by inertia and stops at the position as shown in FIG. 6 (d). It is important that the stop position of sector 1 gear 25 not be engaged with rack 18. In consideration of maintenance of the gun, it is desirable that the gun main body 1 be rotated about the hinge 9 and be opened so that the inside can be inspected as shown in FIG. According to this, the stop position of the sector 1 gear 25 can be set to a position not engaged with the rack 18 and can be easily opened as shown in FIG. When sector 1 gear 25 and rack 18 are engaged, sector 1 gear 25 and rack 18 are stressed so that they can not be opened easily. However, in this embodiment, such a state is obtained. Can be avoided.
- the amount of rotation from the detection of the rotation reference position of the sector 1 gear 25 to the stop of the motor 22 depends on the inertia of the motor 22, friction loss of the gear mechanism, etc. Force of the motor 22 or gear mechanism If it is decided, the amount of rotation is almost determined, so measure the amount of rotation in the prototype and set the rotation reference position detection holes 40 so that the sector 1 gear 25 and the rack 18 stop at the position where they do not engage. it can.
- the stop position also changes depending on the voltage fluctuation of the battery 27. However, if the battery 27 voltage is detected and the voltage drops below a predetermined threshold By providing a safety device to stop the operation, etc., it is possible to further reduce the fluctuation range of the stop position. With regard to the voltage drop of the battery 27, it may be better to provide a display such as a display prompting charging when the battery voltage reaches the threshold or when the threshold is reached.
