DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail below by way of example with reference to the drawings. However, the components described in the following embodiments are merely examples, and the technical scope of the present invention is not intended to be limited thereto.

[First embodiment]
A toy gun 100 as a first embodiment of the present invention will be described using FIG. 1. FIG. 1 is a partially enlarged view showing the configuration of a toy gun according to a first embodiment of the present invention.

As shown in FIG. 1, the toy gun 100 has a bullet path 103 from a supply port 104 through which bullets 130 supplied from a magazine 120 enter a chamber chassis 140 to a nozzle contact position 160 where the bullets 130 abut against a nozzle 150. , includes a monitoring unit 101 that monitors the movement of bullets. The toy gun 100 also includes an auto-stop control unit 102 that stops firing the bullet if it is determined that the bullet has stopped moving in the bullet path 103 even if the trigger is input in the firing mode. Equipped with.

Even when bullets 130 are supplied from a magazine 120 that does not have a follower, such as a continuous fire magazine, by monitoring the behavior of the bullets in the bullet path 103, it is possible to detect out of bullets and perform automatic stop. This results in more realistic movements, allowing the user to obtain an operational feeling closer to that of a real gun.

The monitoring unit 101 is an ON/OFF switch provided on the bullet path 103. The auto-stop control unit 102 determines that the movement of the bullet has stopped in the bullet path 103 when the output from the ON/OFF switch 101 is continuously ON for a first time or continuously OFF for a second time. and auto-stop. That is, the current supplied from the battery 121 to the motor 123 via the trigger switch 122 is cut off. Here, the "first time" and "second time" can be arbitrarily set by the program creator. The toy gun 100 further includes an auto-stop release unit 124, and when a bullet is loaded into the magazine and a predetermined operation is performed, the auto-stop is canceled and the trigger can be pulled again to fire the bullet. becomes possible.

Here, the first time and the second time measured by the auto-stop control unit 102 are times that are greater than or equal to twice and less than ten times the continuous firing interval. For example, when the firing interval is 0.07 seconds (13 shots fired per second), the auto-stop control unit 102 is continuously turned on for 0.25 seconds or turned off continuously for 0.25 seconds. It detects this and automatically stops.
The ON/OFF switch 101 is not turned on by the bullet moving from the supply port 104 toward the nozzle contact position 160, but is turned ON by the bullet pushed back from the direction of the nozzle contact position 160. As a result, even if the bullet supply force of the continuous-fire magazine weakens, the resistance caused by the switch will not interfere with bullet feeding.

The ON/OFF switch 101 is an ultra-small microswitch having a pin push button 111. The BB bullet diameter is 6 mm, the passage width is about 7 mm, and the pushing depth of the pin push button 111 is about 1 mm.

The BB bullet loaded by the nozzle 150 from the nozzle contact position 160 to a predetermined position of the inner barrel 170 is moved by the compressed air generated by the forward movement of the piston 180 to the front where the outer barrel (not shown) is extended. (direction of arrow 175).

FIG. 2 is a partially enlarged view showing the configuration of the toy gun 100 in a state where BB bullets are supplied from the magazine.

The ON/OFF switch 101 is provided on the inner wall outside the curve (bending part) of the bullet path 103, and when the BB bullet is supplied from the lower supply port 104, the ON/OFF switch 101 must be turned ON. The nozzle can be moved to the nozzle contact position 160. Specifically, the BB bullet contacts the pin push button 111 when passing toward the nozzle contact position 160. However, due to the repulsive tension that the pin push button 111 itself has, it is not possible to continue pushing the BB bullet only by the force generated when it passes upward. In other words, it does not turn on continuously for 0.25 seconds. In other words, the ON/OFF switch 101 has a repulsive tension to the extent that it is not affected by the movement of the bullet from the supply port 104 toward the nozzle contact position 160. Thereby, the movement of the BB bullet can be monitored without hindering the movement of the BB bullet due to the tension of the ON/OFF switch 101.

FIG. 3 is a diagram for explaining a situation in which the pin push button 111 is pressed. When the BB bullet advances upward and reaches the nozzle contact position 160, pressure is applied from the closed nozzle 150 and the next bullet 331 is pushed from above. The next bullet 331 pushed by the pressure from above moves back a little. Even when the nozzle 150 closes and a pressing force is applied to the next bullet 331 from above, the force that pushes up the BB bullet from the magazine continues to work, so that forces are applied to the bullet on the path from above and below. Therefore, the BB bullet 332 moves to a position where the pin push button 111 can be kept pressed. As a result, if there are BB bullets in the magazine 120 and BB bullets continue to be supplied to the bullet path 103, the ON/OFF switch 101 will alternately turn ON and OFF at approximately 0.07 second intervals. On the other hand, if there are no more BB bullets in the magazine 120, there will be no more force to push up the BB bullets from the magazine 120, so the only force applied to the BB bullets 331 will be from above. In this case, the BB bullet 332 cannot obtain enough force to continue pushing the pin push button 111. Therefore, the pin push button 111 is turned off continuously for 0.25 seconds or more. The auto-stop control unit 102 detects this and automatically stops the supply of current from the trigger switch 122 to the motor 123.

There are cases where the force of the mainspring (not shown) in the magazine 120 weakens, and the BB bullet 332 is barely able to press the pin push button 111 in a state where the force pushing up the BB bullet from the magazine 120 is extremely close to zero. In this case, when the nozzle 150 is opened and a bullet is fed, even if there is no pushing force from the magazine 120, the next bullet 331 can be pushed up into the bullet feed port. In other words, the ON/OFF switch 101 has a tension that assists in pushing up the bullet even near the opening of the mainspring, where the force with which the magazine 120 pushes up the bullet becomes unstable.

As described above, according to the present embodiment, it is possible to detect whether the magazine 120 is out of bullets or the mainspring by checking whether the BB bullet is moving or not in the bullet path.

Since the number of bullets and mainsprings differ depending on the magazine, it is not possible to detect when a magazine is out of bullets by counting the number of shots fired. However, with the above configuration, by monitoring the behavior of the BB bullets in the bullet path, it is possible to detect whether the bullets are out or the mainspring is out, and to automatically stop the machine, no matter what magazine is attached. Since there is no need to drive the motor and the behavior of the piston and weight when no bullets are ejected, it is possible to provide a realistic operating feel that is very close to that of a real gun. Note that the monitoring unit is not limited to the above-mentioned ON/OFF switch. It may also be a switch of another mechanism, such as an optical switch.

[Second embodiment]
Next, a toy gun according to a second embodiment of the present invention will be described using FIG. 4. FIG. 4 is a partially enlarged sectional view for explaining the internal configuration of the toy gun 400 according to the present embodiment. The toy gun according to this embodiment differs from the first embodiment in that the pin push button 411 is located higher. The other configurations and operations are the same as those in the first embodiment, so the same configurations and operations are given the same reference numerals and detailed explanation thereof will be omitted.

In the configuration shown in FIG. 4, the position of the pin push button 411 is higher than in the first embodiment and is in a straight line, so the BB bullet will not come into contact with the nozzle without turning on the pin push button 411. Unable to move to position 160. Therefore, the ON/OFF switch 101 is turned on at the timing when the BB bullet moves upward.

In this embodiment as well, it is possible to detect if the magazine 120 is out of bullets or out of the mainspring by checking whether the BB bullet is moving or not in the bullet path.
