The bullet feeding device A having the above configuration is appropriately installed in a magazine 50 of a toy gun G that can automatically and continuously fire bullets B using a pressure medium, as shown in FIG. 5, for example.

When the rigger 51 is pulled in the direction of the arrow, the loaf bar 52 rotates and the power unit 53 forming the screw 1 member is driven. Then power unit 5
3 is reciprocated in the front-back direction by a pressure medium 55 such as liquid gas sent from a gas supply cylinder 54. The power unit 1-53 is provided with a hollow pipe 58 having a protrusion 57 that intermittently collides with a crank 56, and the crank 56 moves the reciprocating plate 26 up and down.

Here, the operation mode of the bullet feeding device A will be explained based on FIGS. 6 to 9. First, FIG. 6 shows a stopped state, in which the gear lock portion 30 of the reciprocating plate 26 engages with the gear 23 of the rotating shaft 22, so that the rotary valve supply body 40 is in a temporarily stopped state. In this case, reciprocating plate 2
6 is constantly pressed down in the direction of engagement with the gear 23 by a spring member 35, while the hook piece 27 is detached from the gear 23, and the hook piece is pressed upward by the coil spring 33 via the piece 32. and comes into contact with the hook stopper 16 due to the pressing force.

Next, FIG. 7 shows a state in which a force in the direction of arrow a is applied to the reciprocating plate 26 by the action of the crank 56, and the reciprocating plates 1 to 26 begin to move against the spring force of the spring member 35. . At this time, the gear lock portions 30 of the reciprocating plays 1 to 26 move away from the gear 23, and
The hook piece 27 slides in contact with the hook stopper 16 and pushes out the hook piece with its upper end side wall and slides into the sliding contact portion 3 of the rotating body 36.
Push up 6a. Therefore, the hook piece extruding rotating body 36 rotates somewhat in the direction indicated by the arrow while resisting the spring force of the spring member 37. Next, in FIG. 8, the reciprocating plays 1 to 26 are roughly pushed up by the crank 56, and as a result, the sliding portion 36a of the hook piece push-out rotating body 36 comes off while slidingly contacting the side wall of the upper end of the hook piece 27, and the spring is released. Due to the spring force of the member 37, it rotates in the direction opposite to the direction of the arrow (counterclockwise direction in the drawing), and the sliding portion 36a pushes out the hook piece 27 in the direction of engagement with the gear 23, and the contact portion 36b comes into contact with the stopper piece 15, and the rotating body 3 pushes out the hook piece.
6 indicates a state returned to the initial state. In this case, spring part-1
1= The material 35 is pushed upward by the protruding upper end of the plate-like portion 26a of the reciprocating play 1-26, and spring force is accumulated.

Finally, FIG. 9 shows a state in which the crank 56 lands in the direction of arrow C and the reciprocating plate 26 is pushed down by the spring force of the spring member 35. At this time, hook piece 27 is gear 2
3, the rotating shaft 22 rotates by one pitch in accordance with the downward movement of the hook piece. Then, the rotary bullet supply body 406 rotates together with the rotation shaft 22. When the rotary bullet supply body 40 rotates 60 degrees in this embodiment while sliding on the surface of the bullet supply component blank plate 1, the first bullet B that has entered one of the valve ring entry passages 45 is Figure and 11th
As shown in the figure, the notch of the elastic cutout wall 44 is the elastic section 19.
The next bullet B1 was separated from the first bullet B by passing through the
The bullet passes through the through hole 3 and is guided by the guide projecting wall 4 while being sent to the projectile opening side. Then, the delivered bullet B is once set in the packing 60, and the pressure medium 55
is fired from the gun barrel 61. In this way, in this embodiment, when the crank 56 is intermittently rotated by the power unit 53, the reciprocating plate 26 moves up and down, and the rotation shaft 22 and the rotary bullet supply body 40 are rotated by one-sixth.
The bullets located at the head of each valve ring entry path 45 are successively sent out to the bullet firing port side while being separated from the next bullet B1.

"Different Examples" Next, different embodiments of the present invention will be explained.

In the description of this embodiment, the same parts as in the embodiment of the present invention are given the same reference numerals, and redundant explanation will be omitted.

The main difference between the bullet feeding device @AI shown in FIG. 12 and the bullet feeding device A is that the magazine 50 of the toy gun
The point is that a plurality of engaging claw pieces 63 are provided to engage with arc-shaped stopper pieces 62 which are disposed at appropriate locations inside and are displaceable in an outwardly expanding manner.

In this embodiment, six engaging claw pieces 63 are provided protruding from the outer peripheral wall of the support body 41A at predetermined intervals in the circumferential direction.

When the engaging claw pieces 63 are set in this way, even if the gear lock portion 30 of the reciprocating plate 26 separates from the gear 23 in a high speed state as shown in FIG. The rotating bullet supply body 40A
This can be used to prevent reverse rotation.

In the above embodiment, the power unit 53 serves as a drive source for rotating the rotating shaft 22 of the bullet feeder A (AI).
In addition, there is the driving force of the drive motor and the accumulated force of the mainspring.

"Effects of the Present Invention" As is clear from the explanation below, the present invention has the following effects.

(1) The magazine can be designed to have a desired shape and size.

(2) A large amount of bullets stored in the magazine can be picked up one after another by the rotating bullet supply body and sent to the bullet launch port.

(3) In the case of an embodiment in which the rotary bullet supply body is provided with a plurality of valve ring entry passages formed by screw-shaped or spiral bullet guide walls, the rotary bullet supply body rotates once. The leading bullets in each valve ring entry path pass through the through holes one after another, and the next bullets sequentially advance through the eight bullet introduction paths one by one.

Therefore, even if the rotary bullet supply body rotates at a somewhat high speed, it is possible to feed bullets corresponding to the speed.

(4) An elastic section is provided on the cable plate of the bullet supply structure to separate the bullet that attempts to pass through the through hole from the valve ring entry path due to the rotation of the rotary bullet supply body from the next bullet in the skeleton introduction path following the skeleton. In the case of this embodiment, even if the rotary bullet supply body is rotated at high speed, bullets can be reliably fed one by one from the through hole to the bullet firing port side.

Therefore, no bullet feeding failure occurs.
