[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a projectile launching device of a shooting game device according to the present invention is a shooting game device for transporting a bullet stored in a hopper to a projecting means and projecting the bullet to the outside by the projecting means. The projectile launching device, characterized in that it has a projecting tube, a screw conveyor, and a conveyor motor. The bullet carrier pipe connects the hopper and the bullet ejecting means, and the bullets are arranged in a line inside thereof. The screw conveyer is arranged in the hopper and has spiral blades on the outer circumference. When the screw conveyer is rotated, the bullet is conveyed in the direction of the bullet conveying pipe. The conveyor motor rotationally drives the screw conveyor.

[0007]

[Action]

 A plurality of bullets are stored side by side in a row without any gaps inside a bullet carrier pipe extending from the hopper to the bullet ejecting means. The rear end of this row of lines exits from the screw conveyor, and the leading end of the line reaches the ejector. When the screw conveyor is driven by the conveyor motor to rotate about the axis, the bullets in the hopper are pushed by the spiral blades of the screw conveyor to move in the axial direction. By this movement of the bullet, the bullet clogged in the bullet transport pipe moves toward the bullet ejecting means, and the first one is supplied to the bullet ejecting means and further ejected to the outside.

Since the screw conveyor can continuously rotate many times, a large number of bullets can be continuously supplied to the ejection device in a short time. Therefore, a large number of bullets can be continuously fired from the bullet ejecting device in a short time. Also, the plurality of bullets ejected from the hopper are automatically aligned in a row while being transported into the bullet transport tube. Therefore, a special bullet aligning mechanism for aligning bullets is not required, and the structure is simplified accordingly.

【Example】

 FIG. 3 shows an example of a shooting game device provided with a bullet launching device according to the present invention. This shooting game device has a bullet shooting device 1 at the left end of the drawing. A player shoots a bullet 4 from a bullet shooting device 1 aiming at three targets 3 arranged inside a casing 2 of the game device. The bullet 4 is, for example, a relatively light and hollow sphere formed of a thin and hard synthetic resin used in table tennis.

The bullet 4 that contributes to the score by hitting the target 3 or the bullet 4 that does not hit the target 3 against the intention is a game board surface 5 or a housing 2 arranged between the bullet launching device 1 and the target 3. It drops onto the bullet collecting plate 6 provided at the bottom of the. The dropped bullets 4 roll downward according to the inclination of the game board surface 5 or the bullet collecting plate 6 and are collected by the bullet launching device 1.

As shown in FIG. 1, the projectile ejecting device 1 includes a hopper 7 for accommodating bullets 4, a screw conveyor 8 provided at the bottom of the hopper 7, and a projectile operating section 9 simulating a gun. And a bullet carrier tube 10 connecting the bullet firing operation unit 9 and the hopper 7. As shown in FIG. 3, the projectile firing operation unit 9 is arranged on the left end operation panel of the housing 2 by the support rod 11, and can be rotated around the fulcrum 12 as shown by arrow A, and can be rotated by the arrow. It can be rotated around the axis of the support rod 11 as indicated by mark B.

Returning to FIG. 1, the bullet firing operation portion 9 has a trigger lever 13, a bullet ejection device 14, and a bullet detection sensor 15. The trigger lever 13 is operated by a player (not shown) to output a trigger signal, and the trigger signal is sent to the control device 16.

The bullet ejecting device 14 has a pair of rotating bodies 17, 17 which are formed of hard rubber or other elastic body into a disk shape and whose circumferential side surfaces face each other. These rotating bodies 17 are driven by a motor 18 and rotate in opposite directions at high speed as indicated by arrow C. When the bullet 4 is supplied from the left direction between the two rotating bodies 17, that is, inserted, the bullet 4 is ejected to the right of the rotating body 17 at high speed due to the frictional force applied to the bullets 4 from both rotating bodies 17. , Ie fired.

The bullet detection sensor 15 is composed of, for example, a reflection type optical sensor, and is arranged in the vicinity of the bullet feed opening of the bullet ejection device 14, that is, the bullet feed opening to the high-speed rotating body 17. The sensor 15 is fixedly arranged at a position where the bullet 4a located behind the fired bullet 4 can be detected when the bullet 4 is fired from the rotating body 17. The elastic transport tube 10 is formed of flexible rubber, synthetic resin, or the like, or formed of a bellows-shaped cylindrical member, and is freely movable in any direction.

The screw conveyor 8 arranged at the bottom of the hopper 7 has a spiral blade 21 on its outer circumference, and an output shaft 19a of a motor 19 is connected to the right end thereof. A rotation angle sensor 20 is mounted on the output shaft 19a of the motor 19. The rotation angle sensor 20 can be configured by, for example, a so-called encoder having a disc with a slit fixed to the motor output shaft 19a and an optical sensor for detecting the slit in the disc. The rotation angle sensor 20 outputs a pulse signal corresponding to the rotation angle of the motor 19, and the output signal is sent to the control device 16.

In FIG. 1, inside the hopper 7, a bullet transport plate 22 extending in the axial direction of the screw conveyor 8 and connected to the bullet transport tube 10, and an inclined plate 23 are provided. As shown in FIG. 2, the bullet transport plate 22 is provided between the side portion of the screw conveyor 8 and the side wall of the hopper 7. Further, the inclined plate 23 is provided in an inclined state from the upper portion of the side wall of the hopper 7 to the vicinity of the top of the spiral blade 21 of the screw conveyor 8. In FIG. 1, an auxiliary shelf 24 is fixed to the inner surface of the side wall of the hopper 7 at a portion slightly above the portion to which the bullet transport pipe 10 is connected, and projects toward the inside of the hopper. Further, on the upper surface of the inclined plate 23, a plurality of, in the embodiment, three projecting plates 25, which are arranged in parallel with each other at intervals slightly wider than the diameter of the bullet 4, are fixed. These projection plates 25 are provided so as to be inclined with respect to the axial direction of the screw conveyor 8.

The operation of the bullet firing device having the above structure will be described below.

In FIG. 1, when a player (not shown) operates the trigger lever 13 of the bullet firing operation unit 9, a trigger signal is input to the control device 16, and the control device 16 operates the motor 19 based on the trigger signal. Then, the output shaft 19a is rotated once. This one rotation is judged by the controller 16 based on the output pulse from the rotation angle sensor 20. Unless the trigger lever 13 is continuously operated, the rotation of the motor output shaft 19a rotates once and then stops.

When the motor output shaft 19a makes one revolution, the screw conveyor 8 also makes one revolution accordingly. When the screw conveyor 8 rotates once, the bullets 4 which are pushed by the spiral blades 21 provided on the outer periphery of the screw conveyor 8 and are placed on the bullet carrier plate 22 are linearly moved in the axial direction of the screw conveyor 8, particularly in the left direction of the drawing. Be transported. In this case, the pitch interval of the spiral blades 21 is set to be equal to the outer diameter of the bullet 4 in advance, so that one rotation of the screw conveyor 8 conveys the bullet 4 by a distance of one piece.

When only one bullet 4 is conveyed by the screw conveyor 8, a plurality of bullets 4 packed in a line inside the bullet conveying tube 10 are ejected by one bullet 4 toward the bullet firing operation part 9. Shift to another direction. As a result, the front bullet 4a located in front of the high-speed rotating body 17 of the bullet firing operation unit 9 is moved by one bullet 4 and is inserted between both rotating bodies 17, and It is fired to the right in the figure by frictional force. When the trigger lever 13 is continuously operated, the motor 19 continuously rotates and the bullets 4 are sequentially and continuously supplied to the rotating body 17, and thus the bullets 4 are continuously fired from the rotating body 17. . That is, the bullet 4 is continuously fired. The motor 19 has a high-speed rotation capability such that it can rotate several times per second, and therefore, the continuous firing interval of the bullet 4 is extremely short.

In the present embodiment, the bullet carrier tube 10 is configured to be freely movable by a flexible material or a bellows-shaped member. Therefore, even when the bullet firing operation unit 9 is moved as shown by arrow A or B in FIG. 3, the bullet carrier tube 10 can be moved freely by following it.

In FIG. 1, the sensor 15 installed in front of the high-speed rotating body 17 is located at a position where one bullet 4 fired by the bullet ejecting device 14 can be detected, that is, a bullet 4a. It is located in. In other words, as long as the leading bullet 4a of the row of bullets arranged inside the bullet transport tube 10 is placed at the position detected by the sensor 15, the bullet transport tube is rotated by one rotation of the screw conveyor 8. When each bullet 4 inside 10 moves by one, the leading bullet 4a surely enters between both rotors 17 and is fired from that rotor. When the shape or structure of the housing 2 changes, it becomes necessary to change the total length of the bullet carrier tube 10 accordingly. Even when the length of the bullet carrier tube 10 is changed as described above, if the rotation angle of the motor 19 is set to zero while the leading bullet 4a is detected by the bullet detection sensor 15, the rotation angle of the motor 19 becomes The positional relationship between the bullets 4 can always be maintained in a desired fixed relationship.

The main purpose of the screw conveyor 8 is to convey the bullets 4 mounted on the bullet conveying plate 22 provided at the bottom of the hopper 7 toward the bullet conveying pipe 10. However, the hopper 7 When a large number of bullets 4 are stored in the screw conveyor 8, the screw conveyor 8 may carry a group of bullets 4 existing above it to the left in FIG. In this case, one bullet 4 may fall between the pitches of the spiral blades 21 and may not be able to be placed on the bullet carrier plate 22, and the bullet 4 may not be continuously supplied. The projecting plate 25 provided on the tilting plate 23 in the hopper 7 forcibly breaks the groups when the bullets 4 are conveyed by the screw conveyor 8 in groups, so that the pitches of the spiral blades 21 are accurately adjusted. It acts to supply a single bullet 4 to the.

Further, the auxiliary shelf 24 provided on the inner surface of the side wall of the hopper 7 prevents a large number of bullets 4 from concentrating at the entrance of the bullet carrier tube 10 and clogging there, thereby facilitating continuous supply of the bullets 4. .

As described above, in this embodiment, the bullet 4 is devised so as not to be clogged in the hopper 7. However, in some cases, it is possible that the ammunition 4 still gets stuck. In consideration of such a case, the following driving method of the motor 19 is adopted in this embodiment. That is, when the bullet 4 is clogged and the rotation of the screw conveyor 8 is stopped, the rotation stop is detected by the rotation angle sensor 20, and the motor 19 is given a predetermined signal based on the detection signal based on the detection signal. Reverse rotation for a short time. This reverse rotation eliminates the clogging of the bullet 4, and the motor 19 returns to the normal rotation after a short time, whereby the bullet 4 is smoothly conveyed again.

The present invention has been described above with reference to one embodiment, but the present invention is not limited to the embodiment and can be variously modified. For example, the ejecting means is not limited to the one using the pair of high-speed rotating bodies 17 shown in the embodiment, but can be constituted by any other mechanism.

If the length of the bullet carrier tube 10 does not change, or if the rotation angle of the motor 19 can be adjusted to the zero point by some method even if the length changes, the front side of the ejecting device 14 can be adjusted. The bullet detection sensor 15 may not be provided at the position.

[0028]

[Effect of device]

 According to the present invention, bullets are conveyed by rotation of the screw conveyor, and the screw conveyor can be rotated at high speed by being driven by a motor, so that a large number of bullets can be fired in a short time.

Further, since the bullets are automatically arranged in a line inside the bullet carrier tube, and no special alignment mechanism for aligning the bullets is required, the structure is very simple.
