By rotating, the head portion 16b is lifted from the "ga" position (the striking position) of the figure to the "me" position preparation position (shown by dashed line in FIG. 6).

At the same time, another cam pin 12b at the lower end of the cam gear 12 is raised to contact the first leg 24a of the drive link 24 and push it up, thereby driving the drive link 24 to the link shaft ( 25 is rotated in a counterclockwise direction (dotted dashed line in FIG. 6), so that the connecting pin 23 of the second leg 24b moves downward in the vertical hole 41 of the gunpowder rod 20. To move the gunpowder pusher 20 to the right side of the drawing, and the gunpowder board 19 of the tip of the gunpowder pusher 20 guided horizontally by the guide roller 21 is the gunpowder 46 in the "multi" position Is pushed to the "la" position, whereby the gunpowder 46 in the "la" position is moved to the "horse" position on the striking plate 18 in series.

As the cam gear 12 is further rotated, the cam pin 12a is dismantled with one end of the hitting hammer 16. Accordingly, the hitting hammer 16 is rotated clockwise by the elastic force of the hitting spring 15 to "me". The head portion 16b in the position (preparation position) is rapidly returned to the "ga" position (hit position), and explodes by hitting the gunpowder 46 placed on the striking plate 18 to generate an explosion sound.

At the same time, when another cam pin 12b that is in contact with the first leg 24a of the drive link 24 is disassembled from the first leg 24a, the drive link 24 is driven by the elastic force of the link spring 26.

Therefore, when retreating, no force is applied to the gunpowder gun 47, and the gunpowder press plate 22 elastically presses the gunpowder band 47, so that the gunpowder band 47 is retracted even if the gunpowder holder 20 retreats. Do not reverse.

When the cam gear 12 is further rotated to bring the cam pin 12b to the position of the cam pin 12a in FIG. 6, the cam pin 12b presses the detection lever 38. Accordingly, the switch 29 is turned off. The supply of power from the power source 34 to the drive mutter 5 is cut off and the operation of the drive motor 5 is stopped to complete the explosion operation of one stroke.

At the same time that the switch 29 is turned off by the detection lever 38, the timer 35 starts to operate. After a predetermined time, the timer 35 starts to supply power to the drive motor 5, and the timer 35 stops operating. By repeating this operation, the device of the present invention automatically explodes the explosive and generates an explosion sound.

In other words, the timer 35 and the switch 29 in which OFF-ON are operated alternately are constituted a so-called flip-flop circuit for the driving motor 5, which is well established. Since it is known, the detailed description is omitted.

In addition, the blocking plate 17 prevents hot explosive currents or gases from entering the apparatus of the present invention when the explosive is exploded to explode unused gunpowder or contaminate or corrode the driving part of the apparatus.
