Description

Description Air gun and method of controlling number of firings switching

The present invention relates to an air gun as a model gun, and more particularly to an electronic control of an air gun suitable for arbitrarily switching between single-shot, continuous-shot, and N-shot. Background art

There is an air gun as a model gun that simulates a self-loading rifle, which is used for toys or shooting training. Especially for shooting training, it is desired that the guns be similar in shape and handling to real guns. As a conventional technology of this air gun, there is one disclosed in Japanese Patent Publication No. 7-432328.

In this conventional technology, a kind of pump consisting of a piston and a cylinder is driven by a motor by pulling a trigger, compressed air is ejected from an ejection hole, and a supply is synchronized with this to fire a bullet. And so on. In this prior art, the mechanism for firing a bullet is electrified to be driven by a motor, but the mechanism for firing the bullet is performed by a mechanical mechanism such as a cam. Switching between single-shot and continuous-shot is also performed by a mechanical mechanism consisting of a mechanical tappet arm and a switching lever. In addition, the power supply of the motor ONZOFFF is turned on and off by a mechanical contact switch. In addition, in this conventional technology, switching between single-shot and continuous-shot can be performed by switching the lever. However, in the case of repeated-shot, the motor rotates and a series of operations related to the repeated-shot are repeatedly performed as long as the trigger is held down. Operation stops when the trigger is released.

In the above prior art, the starting and stopping of the firing operation of a bullet Since the switches are turned on and off with a typical switch, contact burn-in and poor contact are likely to cause malfunctions, which has a problem in reliability. In addition, since the switching of single-shot Z firing is performed by a mechanism consisting of a mechanical cam and a leper, malfunctions are likely to occur due to wear and settling.

Also, in the prior art, it was not possible to control how many times the repetitive operation was performed.

Further, in the prior art, there is no means for confirming the presence or absence of a bullet in the magazine. In particular, in the case of continuous operation, there is a problem that useless air strike operation is continued without firing after the final bullet is fired.

According to this prior art, when a trigger is released at an arbitrary timing, the motor also stops at an arbitrary timing. Therefore, there is a problem that the rotating wheel (sector one gear) also stops at an arbitrary rotating position, and stops while engaging with the rack formed on the piston. Stopping with the rotating wheel (sector one gear) and the rack engaged with each other causes the following problems.

(1) The rotating wheels and racks are left idle for a long time with stress applied, causing mechanical failure of the speed reduction mechanism and the piston.

(2) The spring is put in a rest state for a long time in a compressed state. Therefore, the spring effect of the spring is weakened.

(3) Since the wheel and the rack stop while stress is applied, the wheel and the rack cannot be easily disengaged. For this reason, it is not easy to open the inside when performing internal inspection for maintenance.

An object of the present invention is to solve the above-mentioned problems, to easily control how many shots are fired in a continuous operation, and to make it possible to easily switch between single shot, continuous shot, and N shots.

The check valve provided on the biston head 13 (not shown) operates to block the passage of air when the biston 12 moves to the right (as shown in Fig. 6 (d)).

Fig. 6 (c) shows that the sector one gear 25 reaches almost the final position where it engages with the rack 18, and when the sector one gear 25 further rotates, the teeth 3 3 of the sector one gear 25 and the rack are rotated. 18 shows the state immediately before the toothed portion 18 does not engage. At this time, the rotation reference position detection hole 40 of the sector one gear 25 is rotated to the position of the photo sensor composed of the photo diode 39 and the photo transistor 44, and the rotation reference position of the sector one gear 25 is detected by the photo sensor. Is detected. When this rotation reference position issues a motor OFF signal for stopping the motor 22 by the detection signal from the electronic control circuit 47 to the motor power control section 28, the power of the motor 22 is cut off and the motor 22 stops decelerating. I do. In this case, the sector one gear 25 rotates and stops to some extent due to inertia and friction loss of the motor 22 and the reduction gear mechanism. The degree of rotation and stopping is determined by the actual structure, so the positional relationship between the teeth 33 of the sector one gear 25 and the rotation reference position detection hole 40 in Fig. 6 (c) is shown. Since it is difficult to obtain the exact value by calculation, it is difficult to determine exactly what should be done on a trial basis. FIG. 6 (d) shows a state in which the sector one gear 25 is stopped in this way. At this time, the toothless portion 34 of the sector 1 gear 25 faces the rack 18 so that the sector 1 gear 25 and the rack 18 do not mesh with each other, and the piston 1 2 is disengaged with the sector 1 gear. It is released from the pressing force of the rack 25 and the rack 18 and is urged rightward by the pressing force of the spring 15. At this time, the air in the space 62 between the piston head 13 and the cylinder head 11 is compressed, and the air in the center hole 57 of the cylinder head 11 is strongly pushed in the direction of the barrel 21. Put out. As a result, 弹 19 is vigorously pushed rightward in barrel 21, and bullet 19 is fired.

Thus, when the rotation reference position of the sector one gear 25 is detected and the firing operation is stopped, the toothless portion 34 of the sector one gear 25 and the rack 18 always stop so as to face each other. it can. The pistons 12 are always seated at the position where the firing operation starts.

In addition, even if the rotation reference position of the sector one gear 25 is detected in FIG. 6 (c), a motor OFF signal for stopping the motor 22 is sent from the electronic control circuit 47 to the motor power control unit 28. If not, the operation shown in Fig. 6 is repeated continuously, and the continuous operation is performed.

Next, the configuration of the electronic control circuit 47 for controlling the firing operation of the gun will be described.

FIG. 7 shows a control block of the electronic control circuit 47. Reference numeral 49 denotes a microcomputer (microphone computer). Microcomputer 49 has presence / absence detection switch 41 1 signal, trigger switch 37 signal, single / continuous and single-shot ZN switching means 52 2, select switch 51 signal, sector 1 gear 25 rotation The rotation reference position detection signal from the reference position detection unit 50 is input, and the motor ON / OFF signal is output to the motor power control unit 28 via the amplifier 53. 43 and 48 described above indicate connectors. When the motor ON signal is output from the microcomputer 4g, the semiconductor switch of the motor power control unit 28 is turned on, and the voltage of the battery 27 is applied to the motor via the power control unit 28. The motor 22 is rotated by being supplied with electric power. However, when the microcomputer 49 outputs a motor OFF signal, the electric power from the battery 27 is cut off by the power supply control unit 28 and stopped. Reference numeral 50 denotes a rotation reference position detection unit constituted by a photosensor comprising a photo diode 39 and a phototransistor 44 and a sector one gear 25. The detailed operation of the microcomputer 49 will be described later with reference to FIG. 9 and the control flowchart.

The configuration of the electronic control circuit 47 will be described in more detail with reference to FIG.

In FIG. 8, reference numeral 49 denotes a microcomputer, which is operated by a control power supply V cc generated from a battery 27. Light emitted from the photo diode 39 is received by the photo transistor 44 through the rotation reference position detection hole 40 of the sector one gear 25. The output of the photo transistor 44 is amplified by the operational amplifier 54 and input to the microcomputer 49. When the light emitted by the photodiode 39 is received by the phototransistor 44 through the rotation reference position detection hole 40 of the sector one gear 25, the phototransistor 44 is turned on, the output of the operational amplifier 54 also changes, and the rotation reference position detection signal is output. Is obtained.

The microcomputer 49 receives a contact signal from the trigger switch 37 and can detect whether the trigger 3 has been pulled. Also, the contact signal of the bullet presence detection switch 41 is input, and it can be detected whether or not the bullet 19 is present in the magazine 4. The switching means 52 for single-shot mode and single-shot mode / N-shot mode is formed so that a jumper wire can be inserted on the printed circuit board of the control circuit. Depending on whether or not a jumper wire has been inserted into the switching means 52, for example, if a jumper wire is inserted, it will be switched to single-shot mode and if no jumper wire is inserted, it will be switched to single-shot mode / N-shot mode. Can be done. Needless to say, the distinction between the single-shot Z fire and the single-shot ZN fire depending on the jumper wire insertion state may be reversed from the example described above.

5 1 is a select switch, which is a three-point switch. At each contact position, it can be switched between "single", "continuous" and "safe". If “Safe” is selected here, firing will not be performed even if trigger 3 is pulled.

An amplifier 53 amplifies the motor ONZOFF signal output from the microcomputer 49. The output of the amplifier 53 is input to the gate of the MOS FET of the motor power control unit 28. MO S—FET is located between the battery 27 and the motor 22, and functions as a switch for turning ON / OFF the voltage of the motor 22. Therefore, when the MOS FET is turned on by the motor ON signal from the microcomputer 49 and a voltage is applied to the motor 22, power is supplied from the battery 27, and the motor 22 is driven to rotate. Further, if the MOS FET is turned off in response to the motor OFF signal from the microcomputer 49, the electric power from the battery 27 is cut off by the motor 22, and the motor 22 stops rotating. The output shaft of the motor 22 is combined with a reduction gear 24 so as to rotationally drive one sector gear 25.

(First Embodiment of Control)

Next, the firing control of the bullet will be described in detail using a control flowchart.

FIG. 9 shows a first embodiment of the control, and is a flowchart for controlling a single operation.

First, control is started in step 100, and in step 101, it is checked whether the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 102 and the process returns to step 101.

This watchdog timer WDT has a microcomputer 49. In this case, the watchdog timer WDT is periodically reset so that no error signal is output.However, if the microcomputer 49 operates abnormally, the above-mentioned periodic reset of the watchdog timer WDT is performed. This is to stop the operation by issuing an error signal and activating the safety device. The timer value of the watchdog timer WDT is set as, for example, 100 Oms at the initial stage when the power of the microcomputer 49 is turned on. Since the watchdog timer is a well-known technique, its description is omitted here.

If it is detected in step 101 that the trigger switch 37 has been pressed, it is checked in step 103 whether or not there is a bullet 19 in the magazine 4. This is executed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF. When there is a bullet 19 in the magazine 4, the bullet presence detection switch 41 is pushed upward by the bullet presence detection switch pressing member 42, so that the bullet presence detection switch 41 is turned off.

If it is detected in step 103 that there is no bullet 19 in the magazine 4, the process proceeds to step 104 and the power of the motor 22 is turned off. At this time, 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. Upon receiving this signal, the motor power control unit 28 switches 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 be a semiconductor switch. Although a bipolar transistor can be used as the semiconductor switch, it is preferable to use a MOS-FET from the viewpoint of power saving. Using a MOS-FET (MOS field effect transistor) can extend the life of the battery 27. Then go to step 105 and after a 20 ms wait time return to step 101. This waiting time is provided for stabilizing the control, and is not limited to 20 ms.

If it is detected in step 103 that there is 弹 19 in the magazine 4, the process proceeds to step 106 and the motor power is turned ON. At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power control unit 28 turns on MOS-FET, and supplies power to the motor 22 from the battery 27. As a result, the motor 22 starts rotating, and the sector one gear 25 rotates via a reduction mechanism such as the motor shaft 23 and the reduction gear 24.

Next, in step 107, it is checked whether or not the rotation reference position of the sector one gear 25 has been detected. When the reference position detection hole 40 of the sector gear 25 rotation of the sector one gear 25 passes through the location where the photosensor composed of the photodiode 39 and the phototransistor 44 is located, the light from the photo diode 39 is generated. Is passed through the rotation reference position detection hole 40 of the sector one gear 25, the phototransistor 44 receives this light, and this signal is amplified by the operational amplifier 54 and input to the microcomputer 49. Is detected. When the photo sensor is not at the position of the rotation reference position detection hole 40, the phototransistor 44 does not receive this light, so that the rotation reference position detection signal is not input to the microcomputer 49. At the beginning of the rotation of the motor 22, the rotation position is as shown in FIGS. 6 (d) and 6 (a) before the sector gear 25 engages with the rack 18, and the photo sensor rotates. Since it is not at the position of the reference position detection hole 40, the rotation reference position of the sector one gear 25 is not detected. If the rotation reference position of sector 1 gear 25 is not detected, return to step 106 and repeat step 106 'until the rotation reference position of sector 1 gear 25 is detected. Repeat steps 107.

When the rotation reference position of the sector one gear 25 is detected in step 107, the process proceeds to step 108 to output a signal for turning off the motor power supply. At this time, the rotation reference position detection hole 40 of the sector-one gear 25 is located at the position of the photo sensor as shown in FIG. 6 (c). At this time, the microcomputer 49 outputs the motor OFF signal to the signal amplifier 53, and the amplifier 53 amplifies the signal and sends it to the motor power controller 28. Upon receiving this signal, the motor power control unit 28 shuts off the power supplied from the battery 27 to the motor 22 by the power switch.

The motor 22 whose power is cut off does not stop immediately, but rotates to some extent by inertia and stops at the position as shown in FIG. 6 (d). It is important that the stop position of the sector-one gear 25 is a position that does not engage with the rack 18. Considering the case of maintenance of the gun, it is desirable that the gun body 1 be constructed so that it can be opened by rotating the gun body 1 around the hinge 9 so that the inside can be inspected as shown in Fig. 10. According to this, the stop position of the sector-one gear 25 can be set at a position where it does not engage with the rack 18 and can be easily opened as shown in FIG. When the sector one gear 25 and the rack 18 are engaged, the sector one gear 25 and the rack 18 are under stress, so that they cannot be opened easily. Can be avoided.

The amount of rotation from the detection of the rotation reference position of the sector-to-gear 25 to the stop of the motor 22 depends on the inertia of the motor 22, the force S that changes due to the friction loss of the gear mechanism, the inertia of the motor 22 and the gear. Once the mechanism is determined, the amount of rotation is almost determined, so measure the amount of rotation in the prototype and fit the rotation reference position detection hole 40 so that the sector 1 gear 25 stops at the position where the rack 18 does not engage. be able to. The stop position also changes due to voltage fluctuations in battery 27. However, if the voltage of the battery 27 is detected and a safety device such as stopping the operation when the voltage falls below a predetermined threshold value is provided, the fluctuation range of the stop position can be further reduced. Regarding the voltage drop of the battery 27, it is better to provide an indication such as an indication to prompt charging before the battery voltage reaches the threshold value or when the battery voltage reaches the threshold value.

After outputting a signal to turn off the motor power supply in step 108, proceed to step 109 to check whether the trigger switch 37 is ON. If the trigger switch 37 is ON, proceed to step 110 to reset the watch dog timer and return to step 109.

If it is detected in step 109 that the trigger switch 37 has become OFF, the flow proceeds to step 105, and after a waiting time of 20 ms, the flow returns to step 101, and thereafter the above operation is continued.

According to the operation shown in the above flowchart, a single operation can be performed by pulling the trigger 3 once, and then a single operation is performed in the same manner as when the trigger 3 is pulled. It can perform a single-shot operation that fires one bullet each time it is pulled.

According to the embodiment, since the rotation reference position of the sector one gear 25 is detected and the single operation is stopped, the operation is reliably stopped at a position where the sector one gear 25 and the rack 18 do not engage with each other. Can be done. Therefore, the gun body 1 can be easily opened as shown in FIG. 10, and the maintenance of the inside becomes easy. In addition, since the operation can be stopped at a position where the sector one gear 25 and the rack 18 do not engage with each other, the spring 15 can be kept free from stress when a gun or the like is stored. It is possible to suppress the deterioration of elasticity of 15. In addition, the operation can be stopped at a position where the sector one gear 25 and the rack 18 do not mesh with each other, so that unreasonable stress is not applied to the rack 18 and the biston 12 when storing the gun, etc.ゃ Reliability of piston part Can be improved. Further, according to the embodiment of the present invention, the operation can be stopped when the bullet 19 is lost in the magazine 4, and no useless air shooting operation is performed.

(Second embodiment of control)

FIG. 11 shows a second embodiment of the control, and is a flowchart for controlling the continuous operation.

First, control is started in step 120, and in step 121, it is checked whether or not the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 122 and the process returns to step 122.

If it is detected that the trigger switch 37 is depressed in Step 1 21, it is checked in Step 1 2 3 whether there is a bullet 19 in the magazine 4. This is performed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF. When there is a bullet 19 in the magazine 4, the bullet presence detection switch 41 is pushed upward by the bullet presence detection switch pressing member 42, and the switch is turned off. If it is detected in step 1 2 3 that there is no 弹 19 in the magazine 4, the process proceeds to step 1 24 and the power of the motor 22 is turned off. At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power supply control unit 28 shuts off the power supplied from the battery 27 to the motor 22 with MOS-FET.

Then go to step 1 25 and return to step 1 21 after a waiting time of 20 ms. This waiting time is provided for stabilizing the control, and is not limited to 20 ms.

If it is detected in step 1 2 3 that bullet 19 is in magazine 4, Proceed to step 1 26 to turn on the motor power. At this time, 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. Upon receiving this signal, the motor power control unit 28 turns on the MOS-FET and supplies power to the motor 22 from the notch 27. As a result, the motor 22 starts rotating, and the sector one gear 25 rotates via a reduction mechanism such as the motor shaft 23 and the reduction gear 24.

Next, in step 127, it is checked whether the rotation reference position of the sector one gear 25 has been detected. If the rotation reference position of sector 1 gear 25 is not detected, return to the beginning of step 127 and repeat step 127 until the rotation reference position of sector 1 gear 25 is detected.

If the rotation reference position of the sector-one gear 25 is detected in step 127, the process proceeds to step 128.If the trigger switch 37 is not ON in step 128, the process proceeds to Outputs a signal to turn off the power. At this time, the rotation reference position detecting hole 40 of the sector one gear 25 is located at the position of the photo sensor as shown in FIG. 6 (c). At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power control unit 28 shuts off the power supplied to the motor 22 from the battery 27 by the power switch.

After outputting a signal to turn off the motor power in step 129, proceed to step 125, return to step 121 after a waiting time of 20 ms, and continue the above operation.

If the trigger switch 37 is ON in step 1 28, the flow advances to step 130 to check whether or not the magazine 4 has 弹 19. If it is detected that bullet 19 is in magazine 4, go to step 13 and watch Clear dog timer WDT and return to step 127.

If it is detected in step 130 that there is no bullet 19 in the magazine 4, the process proceeds to step 12 and the power of the motor 22 is turned off. After outputting a signal to turn off the motor power supply in step 129, proceed to step 125 and return to step 101 after a waiting time of 2 O ms, and continue the above operation. According to the present embodiment, the bullet 19 can be fired continuously while the trigger 3 is pulled, and when the firing is stopped, the trigger 3 is released. Detects the rotation reference position of one gear 25 and starts the stop operation. Therefore, the last stop position of the continuous fire can be managed with high accuracy as in the case of the single operation of the first embodiment, and the stop can always be performed in a state in which the sector gear 25 and the rack 18 do not engage with each other. it can.

Therefore, similarly to the first embodiment, the gun main body 1 can be easily opened as shown in FIG. 10 and the internal maintenance becomes easy. In addition, since the operation can be stopped at a position where the sector one gear 25 and the rack 18 do not mesh with each other, the spring 15 can be kept free from stress when a gun or the like is stored. 5 can suppress the deterioration of elasticity. In addition, since operation can be stopped at a position where the sector 1 gear 25 and the rack 18 do not fit together, excessive stress is not applied to the rack 18 and the piston 12 when storing the gun. Therefore, the reliability of the speed reduction mechanism and the biston portion can be improved. Further, according to the embodiment, the operation can be stopped when the magazine 19 is lost in the magazine 4, and the useless air shooting operation is not performed.

(Third Embodiment of Control)

FIG. 12 shows a third embodiment of the control, and is a flow chart of the N-time fire control in which the N-time fire operation can be performed. N can be any positive integer greater than or equal to two. The present inventor manufactured N as 3 but is not limited to this. First, in step 140, control is started. In step 141, it is checked whether the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 122 and the process returns to step 122.

If it is detected in step 14 that the trigger switch 37 is being pressed, it is checked in step 144 that the magazine 4 has a bullet 19. This is performed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF. When there is a bullet 19 in the magazine 4, the bullet presence detection switch 41 is pushed upward by the bullet presence detection switch pressing member 42, and the switch is turned off. If it is detected in step 144 that there is no bullet 19 in the magazine 4, the flow proceeds to step 144, and the power of the motor 22 is turned off. At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power control unit 28 cuts off the power supplied to the motor 22 from the battery 27 by the MOS FET.

Then go to step 144 and return to step 141 after a waiting time of 20 ms. This waiting time is provided for stabilizing the control, and is not limited to 20 ms.

If it is detected in step 144 that there is 4 19 in the magazine 4, the process proceeds to step 146 and N is set in the power counter CNT 1. N is the number of barrages and is a positive integer value of 2 or more.

Next, proceed to step 147 to turn on the motor power. At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power supply control unit 28 turns on the MOS-FET, and the motor Power to the motor 22. As a result, the motor 22 starts to rotate, and the sector one gear 25 rotates via a reduction mechanism such as the motor shaft 23 and the reduction gear 24.

Next, at step 148, it is checked whether or not the rotation reference position of the sector one gear 25 has been detected. If the rotation reference position of sector 1 gear 2 5 is not detected, return to the beginning of step 1 4 8 to select sector sector,-? 5 rotation reference position

Repeat steps 1 4 and 8 until a position is detected.

If the rotation reference position of the sector-one gear 25 is detected in step 148, the process proceeds to step 149. In step 149, it is checked whether or not the magazine 19 has the bullet 19 in the magazine 4. When it is detected that there is no bullet 19 in the magazine 4, the process proceeds to step 12 and the power supply of the motor 22 is turned off. After outputting a signal to turn off the motor power supply in step 129, the process proceeds to step 125 and returns to step 101 after a wait time of 2 ms, and thereafter the above operation is continued. If it is detected in step 14 that the magazine 4 has a bullet 19, the process proceeds to step 151, and 1 is subtracted from the value of the counter CNT1. Check if 0 is subtracted as a result of subtracting 1. If it is not 0, it returns to step 1 48 and repeats the processing from step 1 48 to step 15 1 until it becomes 0.

If it is detected in step 15 1 that the value of the counter C N T 1 has become 0, proceed to step 15 2 and turn off the power of the motor 22.

Next, proceeding to step 153, if the trigger switch 37 is ON, the dog dog timer WDT is cleared and the process returns to the beginning of step 153.

If the trigger switch 37 is not ON, proceed to step 144, return to step 141 after a waiting time of 2 Oms, and continue the above operation. According to the present embodiment, an arbitrary number of N consecutive firings can be performed, and the N consecutive firing operation can be interrupted by releasing trigger 3 during the N consecutive firings. In the last operation, the rotation reference position of the sector one gear 25 can be detected and stopped as in the single operation of the first embodiment. Therefore, the last stop position of N consecutive fires can be managed with high accuracy as in the single operation of the first embodiment, and the stop is always performed in a state where the sector gear 25 and the rack 18 do not mesh with each other. be able to. Therefore, as in the first embodiment, the gun body 1 can be easily opened as shown in FIG. 10, and the maintenance of the inside becomes easy. In addition, since the operation can be stopped at a position where the sector-one gear 25 and the rack 18 do not engage with each other, the spring 15 can be put in a state where no stress is applied to the spring 15 when storing a gun or the like. It is possible to suppress the deterioration of the elasticity. In addition, the operation can be stopped at a position where the sector one gear 25 and the rack 18 do not mesh with each other, so that the rack 18 and the piston 12 are not subjected to excessive stress during storage of the gun, etc. And the reliability of the piston part can be improved. Further, according to the embodiment, the operation can be stopped when the magazine 19 is lost in the magazine 4, and the useless air shooting operation is not performed.

(Fourth embodiment of control)

FIG. 13 shows a fourth embodiment of the control capable of switching between single-shot and continuous-shot operations. Single operation is based on the first embodiment, and continuous operation is based on the second embodiment.

First, control is started at step 160, and at step 161 it is checked whether the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 162 and the process returns to step 161.

If it is detected in step 161 that the trigger switch 37 is pressed, it is checked in step 163 whether or not the magazine 4 has 弹 19. This is done by inputting the signal of the presence / absence detection switch 41 to the microcomputer 49, It is executed by checking whether the signal is ON or OFF.

If it is detected in step 16 that there is no bullet 19 in the warehouse 4, the process proceeds to step 164, and the power of the motor 22 is turned off. At this time, the microcomputer 49 outputs the 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. Upon receiving this signal, the motor power supply control unit 28 shuts off the power supplied from the battery 27 to the motor 22 with MOS-FET.

Then proceed to step 165 and after a 20 ms wait time return to step 161. This waiting time is provided for stabilizing the control, and is not limited to 20 ms.

If it is detected in step 16 that there is a bullet 19 in the magazine 4, the process proceeds to step 166, and it is checked whether the bullet is single or continuous.

Switching between single shot and continuous shot is performed by the select switch 51. The select switch 51 is provided on the side surface of the gun body 1 as shown in FIG. As shown in Fig. 8, the select switch 51 is a switching switch that has single-sided, repetitive-side, and safety-side contacts.When switching to single-sided, +5 V is input to the microcomputer 49, and when switched to continuous-side When 15 V is input to the microcomputer 49 and input to the safe side, 0 V is input to the microcomputer 49. The microcomputer 49 determines single shot and repeated shot based on these three values. Note that the safe side does not perform a firing operation. It goes without saying that the combination of these three values is not limited to this embodiment.

If it is determined in step 166 that it is one shot, the process proceeds to step 166. Step 167 carries out processing of a single operation of the block S1 shown by a broken line in FIG. If step 1 67 has been exited, proceed to step 1 65, return to step 1 after a waiting time of 20 ms, and repeat the above operation | m <3. If it is determined in step 166 that the fire is continuous, the process proceeds to step 168. Step 168 carries out processing of the single operation of the block C1 shown by the broken line in FIG. If the process exits from step 166, the process proceeds to step 165. After a wait time of 2 Oms, the process returns to step 166. Thereafter, the above operation is continued.

According to the present embodiment, it is possible to easily switch between single shot and continuous shot. Moreover, since the single operation is based on the first embodiment and the continuous operation is based on the second embodiment, the rotation reference position of the sector gear 25 is detected at the end of the single operation or the continuous operation. And stop. Therefore, the effects of the first and second embodiments can also be achieved.

(Fifth embodiment of control)

FIG. 14 shows a fifth embodiment of the control capable of switching between single-shot operation and N-shot operation. The one-shot operation is based on the first embodiment, and the N-shot operation is based on the third embodiment. The operation flow of FIG. 14 is similar to that of FIG. 13 of the fourth embodiment. The difference is that in the third embodiment shown in FIG. 13, it is determined whether step 16 6 is single-shot or continuous, and step 16 8 is a block C 1 continuous process indicated by a broken line in FIG. On the other hand, in the present embodiment shown in FIG. 14, it is determined whether the step 1886 is single-shot or N-shot, and the step 1888 is performed in step N 18 of the block N 1 indicated by the broken line in FIG. The point is that the firing process is executed. The determination of switching between single-shot mode and N-shot mode in step 186 is performed by taking the switching state of the select switch 51 into the microcomputer 49. Other processes are the same as in Fig. 13. That is, Steps 160 to 165 and 167 correspond to Steps 180 to 185 and 187, respectively.

According to the present embodiment, it is possible to easily switch between single-shot mode and N-shot mode. In addition, the single operation is based on the first embodiment, and the N consecutive operation is the Since the third embodiment is basically used, when the single-shot mode or the N-shot mode is completed, the rotation reference position of the sector one gear 25 is detected and stopped. Therefore, the effects of the first and third embodiments can also be achieved.

(Sixth embodiment of control)

FIG. 15 shows a sixth embodiment of the control in which the single-shot mode, the continuous mode, and the N-mode mode can be switched. Single operation is based on the first embodiment, continuous operation is based on the second embodiment, and N continuous operation is based on the third embodiment. The operation flow shown in FIG. 15 is as follows: first, single-shot mode, single-shot mode, and single-shot mode, N-shot mode are performed. Perform single-shot / repeating operation The single-shot / N-repeating operation of the fifth embodiment shown by block B1 in FIG. 14 is performed.

First, control is started in step 190, and in step 191 it is determined whether the operation is single-shot or continuous or single-shot and N-shot. This is to input the signal from the single-shot, continuous-shot Z single-shot, and N-shot continuous selection means 52 shown in FIG. 7 or FIG. 8 to the microcomputer 49 to determine the setting state. If it is determined in step 191 that the operation is single-shot and continuous, the flow advances to step 192 to perform the single-shot and continuous shooting operation of the fourth embodiment shown by block A1 in FIG. If it is determined in step 191 that the operation is single-shot and N-shot, the flow advances to step 193 to perform the single-shot and N-shot operation of the fifth embodiment shown by the block B1 in FIG. The determination of the single shot and the repeated shot in the block A 1 and the block B 1 is similar to that of the fourth and fifth embodiments in that the switching state of the select switch 51 is determined by the microcomputer 49.

According to the present embodiment, it is possible to finally switch to one of the single-shot mode, continuous-shot mode, and N-shot mode. Moreover, the single operation is based on the first embodiment, the continuous operation is based on the second embodiment, and the N continuous operation is based on the third embodiment. Since the present embodiment is based on the first embodiment, the rotation reference position of the sector one gear 25 is detected and stopped at the end of the operation irrespective of whether single-shot or continuous-shot N-shot is selected. Therefore, the effects of the first to fifth embodiments can also be achieved.

(Seventh embodiment of control)

FIG. 16 shows a seventh embodiment of the control in which the operation of the single shot, the continuous shot, and the N shots can be switched. The single operation is based on the first embodiment, the continuous operation is based on the second embodiment, and the N-operation is based on the third embodiment. Is the same. The operation flow of Fig. 16 is as follows. First, ONZOF of the trigger switch 37

It checks the F state, checks if there is a bullet 19 in magazine 4, and then switches between single-shot, continuous-shot, and N-shot operations. First, control is started in step 200, and in step 201, it is checked whether the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 202 and the process returns to step 201.

If it is detected in step 201 that the trigger switch 37 is being pressed, it is checked in step 203 whether the magazine 4 has 弹 19. This is executed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF.

If it is detected in step 203 that there is no 弹 19 in the magazine 4, the process proceeds to step 204 and the power of the motor 22 is turned off.

Then go to step 205 and after a waiting time of 20 ms return to step 101.

If it is detected in step 203 that 弾 19 exists in magazine 4, the process proceeds to step 206 to determine whether single-shot, continuous-shot, or N-shot has been selected. to decide. This is performed by judging the switching state of three select switches (not shown). According to the judgment of Step 206, the processing of Steps 207, 208, and 208 is executed. Step 207 is a processing block S1 shown by a broken line in FIG. 9, step 209 is a processing block C1 shown by a broken line in FIG. 11, and step 209 is a broken line in FIG. The processing block is N1.

The operation flow shown in FIG. 16 is a collective processing of the ON / OFF state check of the trigger switch 37 common to the first to third embodiments, and the processing of whether or not the bullet 19 is present in the magazine 4. The operation flow has been simplified as described above. Further, the operation flow of FIG. 15 is different from the sixth embodiment in that the single-shot mode, the continuous mode, and the N-mode mode are each switched equally. In the sixth embodiment, single-shot and continuous-shot are treated as one large block, and single-shot. N-shot is treated as another large block. In such a case, as shown in FIG. 7 or FIG. This can be implemented by providing a single-shot / repeating / single-shot / N-shot selecting means 52 and a select switch 51. On the other hand, the seventh embodiment is suitable for the case where single-shot, continuous-shot, and N-shot switching are performed by a three-point switch or the like. In addition, the switch for judging the switching may be one of three-point switches for single-shot, continuous-shot, and N-shot switching.

According to the seventh embodiment, the operation can be finally switched to one of single operation, continuous operation, and N continuous operation. Moreover, the single operation is based on the first embodiment, the continuous operation is based on the second embodiment, and the N continuous operation is based on the third embodiment. Even if is selected, at the end of the operation, the rotation reference position of the sector one gear 25 is detected and stopped. Therefore, the effects of the first to fifth embodiments can also be achieved. (Eighth Embodiment of Control)

FIG. 17 shows an eighth embodiment of the control in which the single-shot mode, the continuous mode, and the N-mode mode can be switched. Single operation is based on the first embodiment, continuous operation is based on the second embodiment, and N continuous operation is based on the third embodiment. Same as form.

In the operation flow shown in Fig. 17, continuous fire and N continuous fire are first grouped as continuous fire and separated from single fire, and then continuous fire and N continuous fire are separated. First, in step 220, control is started. In step 222, it is checked whether or not the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 222 and the process returns to step 222.

If it is detected in step 22 that the trigger switch 37 has been pressed, it is checked in step 22 that the magazine 4 has a bullet 19. This is executed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF.

If it is detected in step 2 23 that there is no bullet 19 in the magazine 4, the process proceeds to step 2 24 to turn off the power of the motor 22.

Then go to step 2 25 and return to step 2 21 after a waiting time of 20 ms.

If it is detected in step 2 23 that 弹 19 is in the magazine 4, the process proceeds to step 2 26 to determine whether it is single-shot or continuous / N-shot. This can be executed by providing the select switches 51 shown in FIGS. 7 and 8 and judging the switching state thereof by the microcomputer 49.

If it is determined in step 226 that it is a single shot, the process proceeds to step 227 to execute the processing block S1 shown by the broken line in FIG. This is a process where a single operation is performed. This is a logical flow.

If it is determined in step 226 that the fire is continuous / N fire, the process proceeds to step 228 to determine whether the fire is continuous or N fire. This can be executed by providing a single-shot / single-shot / N-shot selection means 52 shown in FIGS. 7 and 8 and judging the switching state by the microcomputer 49. If it is determined in step 228 that they are fired consecutively, the flow advances to step 229 to execute the processing block C1 shown by the broken line in FIG. This is a processing flow for performing a continuous operation. If it is determined in step 228 that N consecutive firings have been performed, the flow advances to step 230 to execute the processing block N1 shown by the broken line in FIG. This is the process flow for performing N consecutive firings.

Similarly to the seventh embodiment, the common trigger switch 37 checks the ONZ OFF state of the trigger switch 37, and the process of determining whether or not the bullet 19 is present in the magazine 4 is collectively processed in the eighth embodiment. The operation flow has been simplified. According to the eighth embodiment, the operation can be finally switched to any one of the single-shot mode, the continuous mode, and the N-second mode. Moreover, the single operation is based on the first embodiment, the continuous operation is based on the second embodiment, and the N continuous operation is based on the third embodiment. Even if is selected, at the end of the operation, the rotation reference position of the sector one gear 25 is detected and stopped. Therefore, the effects of the first to fifth embodiments can also be achieved.

(Ninth embodiment of control)

FIGS. 18 to 20 show a ninth embodiment of the control. The operation will be described according to the figure.

Starting from step 240 in FIG. 18, the process proceeds to step 241 to perform initialization. Here, the initial value of the watchdog timer used in the following processing is set to 100 ms, and the power of the motor 22 is turned off. Is performed. As described above, the initial value of the watchdog timer is not limited to 100 ms. The process of turning off the power of the motor 22 is performed first to ensure that the motor 22 is stopped.

Next, the process proceeds to step 242 to determine whether it is single-shot Z or single-shot ZN. This can be executed by providing switching means 52 for single-shot / repeating and single-shot ZN and judging the switching state by the microcomputer 49. If it is determined in step 2 42 that the shot is single shot / shot fire, the process proceeds to step 2 43 in FIG. In step 2 43, check whether the trigger switch 37 is pressed. If the trigger switch 37 is not pressed, the watchdog timer WDT is cleared in step 244 and the process returns to step 243.

If it is detected in step 243 that the trigger switch 37 is being pressed, the process proceeds to step 245 to check whether it is single shot or continuous shot. This can be executed by taking the switching state of the select switch 51 into the microcomputer 49. If it is determined in step 2 45 that it is a single shot, the flow advances to step 2 46 to check whether or not the magazine 4 has a bullet 19. This is performed by inputting the signal of the bullet presence detection switch 41 to the microcomputer 49 and checking whether this signal is ON or OFF. When there is a bullet 19 in the magazine 4, the bullet presence / absence detection switch 41 is pushed by the 弹 presence / absence detection switch pressing member 42 to turn the switch ON.

If it is detected in step 2 46 that there is no 弹 19 in the magazine 4, the process proceeds to step 2 49 to turn off the power of the motor 22.

Then go to step 248 and return to step 243 after a waiting time of 20 ms.

If it is detected in step 2 4 6 that 弾 19 is in magazine 4, Proceed to steps 2 4 7. This step 247 shows the one-shot processing of the block S1 shown by the broken line in FIG. After exiting the processing of step 247, the process proceeds to step 248, and returns to step 243 after a waiting time of 20 ms.

If it is determined in step 245 that the shots have been fired consecutively, the flow advances to step 250 to check whether or not there is a bullet 19 in the magazine 4. If it is detected in step 250 that there is no bullet 19 in the magazine 4, the process proceeds to step 249 to turn off the power of the motor 22, and then proceeds to step 248 to wait for 20 ms. After time, return to steps 2 4 3.

If it is detected in step 250 that the bullet 19 is present in the magazine 4, the process proceeds to step 251. This step 251 shows the continuous processing of the block C1 shown by the broken line in FIG. After exiting the process of step 2 51, the process proceeds to step 2 48, and after a waiting time of 20 ms, the process proceeds to step 2 43.

(10th embodiment of control)

FIGS. 21 and 22 show a tenth embodiment of the control in which the number of fired bullets 19 can be counted.

FIG. 21 shows a flow of the single shot operation shown in FIG. 9 in which a counter for counting the number of shot bullets 19 is provided. Similarly, a counter can be provided in the flow of the firing operation of the continuous fire in FIG. 11 and the flow of the fire operation of the N consecutive fire in FIG. The illustration of the continuous fire and the N fire is omitted because they are the same as in FIG. FIG. 22 shows a flowchart in which the numbers of 弹 19 fired in the single shot, the continuous shot, and the N shots are summed up. This will be described below with reference to FIGS. 21 and 22.

In FIG. 21, the same parts as those in FIG. 9 are denoted by the same reference numerals.

First, control is started in step 100, and Reset the value n 1 of counter C 2 to 0. Next, the process proceeds to step 101, and the process up to step 107 is the same as that of the first embodiment shown in FIG. Then, in step 107, it is checked whether or not the rotation reference position of the sector-one gear 25 has been detected.

When the rotation reference position of the sector-one gear 25 is detected in step 107, the process proceeds to step 301. Here, 1 is added to the value of the counter C2. In this case, the counter value is n 1 = 0 + 1 = 1 because only one bullet 19 was fired.

Next, proceed to step 108 to output a signal for turning off the motor power supply. Thereafter, the flow returns to step 101 through steps 109, 110, and 105. Further, when the trigger switch 37 is turned ON, the above operation is repeated, and 1 is further added to the value of the counter C2, so that n1 = 1 + 1 + 1 = 2.

Thereafter, every time the trigger 3 is turned ON and the bullet 19 is fired, the value of the counter C2 is incremented. That is, the counter value is incremented in response to one bullet 19 being fired.

Similarly, in the case of repeated fire, the number of bullets 19 fired can be counted. That is, assuming that the counter in the case of continuous fire is C3, the force counter C3 is reset to 0 after step 120 in FIG. 11 as in FIG. The counter C3 should be incremented by one. In this case, since it is a volley, the bullet 19 is continuously fired in the loop of Step 127 to Step 131, and the force is increased by 1 each time the ball exits Step 127. Therefore, the number of fired bullets 19 can be accurately counted.

Similarly, in the case of N consecutive firings, the number of fired bullets 19 can be counted. That is, assuming that the counter in the case of the continuous fire is C4, the force counter C4 is reset to 0 after step 140 in FIG. It is sufficient to increase the value of the power counter C 4 by 1 after the step 1 4 8. In this case, since it is N consecutive shots, the bullet 19 is fired continuously in the loop from Step 127 to Step 131, and the count is incremented by 1 each time the step 127 is exited, and is counted up to a maximum of N shots. Therefore, even in the case of N consecutive fires, the number of fired bullets 19 can be counted accurately.

The embodiment shown in FIG. 22 is a modification of the single-shot, continuous-shot, and N-shot mode shown in FIG. 16 in the embodiment 7 shown in FIG. The number is calculated and displayed.

First, control is started in step 200, and in steps 400, the values 111, n2, and n3 of the counters C2, C3, and 〇4 are reset to zero. Next, proceeding to step 201, the processing up to step 206 is the same as that of the seventh embodiment shown in FIG. In step 206, it is determined whether one-shot, continuous, or N-shot is selected, and the processing in steps 401, 402, and 400 is performed. Step 401 shows the processing block S2 shown by the broken line in FIG. Step 402 is the one in which the counter C3 is provided by the above-described continuous fire, and Step 4003 is the one in which the counter C4 is provided by the previously described N fire. Specifically, C2 is the first one. In the figure, a counter C3 is inserted after step 127 in step C1, and a counter C4 is inserted after step 148 in block N1 in FIG. 12 in step N2.

Step 4 0. 1 to 4 0 3 _c Step 4 0 4 Step 4 above to execute the processing passing the Step 4 0 4 0:! ~ 4 0 3 of the counter C 2 to C 4 are counted by the n 1 Nn 3 are summed and displayed on the display means. Although the display means is not shown, it can be easily provided by using a control technology using an ordinary microcomputer, and a liquid crystal display can be used. 9 total values can be displayed. Note that this implementation In the embodiment, the counters are set differently for single shot, repeated shot, and Ν repeated shot so that single shot, repeated shot, and Ν repeated shot can be counted respectively, but they may be counted as a common counter. In this case, it is counted as the total value of single shot, repeated shot, and 拘 repeated shot regardless of whether it passes through the single shot, repeated shot, or Ν repeated shot. In this case, step 404 is unnecessary, and step 404 only needs to reset one common counter.

In addition, the above-mentioned count value counted the number of fired 9 19, but if the number of bullets 19 loaded first is initialized, and it counts down every time bullet 19 is fired, You can know the remaining number of bullets. In this case, you can enter a numerical value, but since the number of bullets 19 in the new magazine 4 is known in advance, this is detected when the magazine 4 is set, and the number of bullets 19 is initialized. By doing so, the initial settings can be made automatically. If the initial value is determined, the initial value when a new magazine 4 is set is stored in the internal memory. If an initial setting of an arbitrary numerical value is desired, a key input means for inputting a numerical value may be provided. Although not shown, the key input means can be easily provided by using a control technique using a normal microcomputer.

As a means of counting the number of bullets 19 fired in the above-described tenth embodiment, a rotation reference hole is provided in the sector one gear 25, and the number of passages is counted by a photo sensor. There is no limitation. For example, it can also be counted by counting the movement of a piston or hammer that makes one round trip in response to one bullet 19 firing operation.

The ON / OFF state of the trigger switch 37, the bullet presence / absence detection switch 41, the select switch 51, and the switching means between single-shot mode and single-shot mode した described in the above embodiments is considered to be fail-safe. It is preferable to determine this, but there is no limitation to this. ON, OFF state The situation may be reversed, and it is possible to implement if the state of the switch can be determined.

Further, the electronic control circuit and the control flow described above are not limited to this, and can be modified within the scope of the invention.

In the above description, the free-run is stopped after the rotation reference position of the sector one gear 25 is detected. The reason for this is that the present invention is configured in consideration of the inexpensive configuration, and if it is willing to be expensive, a servo motor may be applied as the positioning means for the sector gear 25. As described above, the value of N in the N consecutive firing can be any positive integer of 2 or more. The present inventor has manufactured N as 3, but is not limited to this. Industrial potential

INDUSTRIAL APPLICABILITY The present invention can be used as a substitute for a real gun in gun shooting training and maintenance training. It can also be used as a model gun for toys. Further, according to the present invention, there is an effect that it is possible to easily control how many shots are fired in a continuous fire operation.

In addition, there is an effect that it is possible to easily switch between a single shot, a continuous shot, and an N shot.

In addition, since the operation is always stopped by detecting the reference position, it can be stopped at a fixed position.
