2. Description of the Related Art Conventionally, a game ball launching device has been used in a ball game machine that hits a game ball and plays a game based on the result of the ball being dropped on the board.

As shown in FIG. 1, such a conventional game ball launching device includes a ball portion 11 provided at the tip of a hammer 10 for launching a game ball 30 and a ball standby portion 21 of a launch rail 20. By hitting the ball 30 at

Here, the hammer 10 is pivotally supported by the support shaft 12 on the side of the anti-ballistic ball portion 11, and a spring 13 between the support shaft 12 and the bullet ball portion 11 for pulling the ball ball portion 11 in the direction of the ball hitting standby portion 21. Is provided. Further, a roller pin 14 is rotatably provided on the hammer 10, and a cam 50 rotated by a motor 40 is pressed against the roller pin 14. Hammer 10
A helical spring is fixed to the bullet portion 11 in order to carry out the bullet efficiently. Reference numeral 15 in the figure denotes a stopper for maintaining the ball portion 11 of the hammer 10 in the hitting ball standby portion 21.

Also, here, as shown in FIG. 3, the cam 50 conventionally used includes a load position 51 for extending the spring 13 for firing and a firing position for projecting a ball in order according to the rotation direction.
52, and a standby position 53 for maintaining the hammer 10 after firing at the same position. Also, here, in general, at the standby position 53 of the cam 50, the surface of the standby position 53 does not contact the roller pin.

Such a game ball launching device has a launch handle device (not shown) that rotates the motor 40 and adjusts the resilience of the spring 13 according to the rotation angle of the launch handle, while moving the ball to the board position targeted by the player. It is a 30 ball.

The movement of the mallet 10 at this time is determined by the shape of the cam 50.

Therefore, when the cam 50 shown in FIG. 3 is used, the ball portion 11 of the hammer 10 is located at the hitting ball standby portion 21 immediately after the ball is hit, and at the same time, the hammer 10 stops its swing by the stopper 15. It is what is being done. At this time, the cam 50 is in a state where the standby position 53 is opposed to the roller pin 14 of the hammer 10 and is not in contact therewith.

Next, although the cam 50 is rotated by the rotation of the motor 40, while the cam 50 is in the standby position 53, the cam 50 does not contact the roller pin 14, so that the ball portion 11 of the hammer 10 is in the hit ball standby portion 21. Becomes

Further, since the ball 30 to be hit next is resupplied to the hitting ball waiting unit 21 after the ball is hit, the ball 30 resupplied to the hitting ball waiting unit 21 is once hit by the hammer 10 in the hitting ball waiting unit 21. It hits the sphere 11 and is maintained in that state.

Then, further rotation of the motor 40 also rotates the cam 50, and the load position 51 of the cam 50 comes into contact with the roller pin 14 in due course. In this state, the motor 40 further rotates, and the rotating cam 50 causes the roller pin 14 to rotate.
Is pressed, and the mallet 10 starts swinging about the support shaft 12 so as to oppose the elastic force of the spring 13.

At this time, the ball 30 resupplied to the hitting ball standby unit 21 for the next ball is with the ball unit 11 of the mallet 10 with the retreat of the ball unit 11 of the mallet 10 from the ball waiting unit 21. Retreat, hitting ball waiting section
It will be kept at the lowest end of 21.

When the motor 40 further rotates in such a state, the cam
The load position 51 of 50 pushes the roller pin 14 further, and the cam 50 moves from the load position 51 to the firing position 52 to disengage the roller pin 14 from the cam 50, and the mallet 10 The ball 11 is swung so as to be pushed out in the direction of the hit ball standby unit 21.

Due to such a swing, the ball portion 11 of the hammer 10 hits the ball 30 of the hit ball standby portion 21.

[Problem to be Solved by the Invention] In such a conventional game ball launching device, the ball 30 replenished for the next ball is first received by the bullet portion 11 of the hammer 10 and then the cam 50 By the rotation, the ball is moved to the lowermost end of the hit ball waiting unit 21, and then the ball is hit.

Here, a helical spring is fixed to the bullet portion 11 of the hammer 10 in order to carry out the bullet efficiently, so that the replenished ball 30 is hammered.
The ball 10 is slightly bounced by the ball section 11 and slightly bounced even at the lowermost end of the hit ball waiting section 21.

Therefore, if the number of bullets per unit time is small, stable bullets can be obtained.
The ball 30 that bounces at the ball portion 11 of the ball, and the ball 30 that bounces at the lowermost end of the hit ball waiting portion 21 also hits the ball before completely stopping,
The stability of the ball was not guaranteed.

Accordingly, the present invention provides a method in which the replenished ball is directly positioned at the lowermost end of the hit ball standby unit by retreating the ball unit from the hit ball standby unit immediately after the end of the ball by rotation of the cam. It is an object of the present invention to provide a game ball launching device capable of increasing the resting time of a ball in a ball hitting standby section to be able to perform a stable ball even if the number of balls per unit time increases. And

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a hammer formed so as to be swingable for hitting a ball in a hit ball waiting portion,
A spring for urging the ball portion provided on the ball portion of the hammer toward the hitting ball standby portion, and a cam for swinging the hammer toward the hitting ball standby portion in accordance with the supply of the ball to the hit ball waiting portion. In addition to the above, the cam is formed so as to have a cam curve such that the ball portion retreats from the ball hitting standby portion immediately after the ball is completed.

[Operation] The game ball launching device according to the present invention immediately retreats from the hit ball waiting unit after the end of the ball.

Therefore, the ball to be supplied to the hitting ball standby portion for the next ball can take a long time to stop at the hitting ball waiting portion, and can be completely stopped before the ball is shot. It is.

Therefore, since a completely stationary ball is shot, the shot can be stably performed.

In particular, even when the number of bullets per unit time is large, stable bullets can be obtained.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view showing the entire game ball launching apparatus, and FIG. 2 is a front view of a cam 50 for explaining a cam shape.

The game ball launching device according to the present invention, like the conventional game ball launching device, as shown in FIG. 1, a ball portion 11 provided at the tip of a hammer 10 for launching a game ball 30, Launch rail 20
The player hits the ball 30 in the hit ball waiting section 21 to hit the ball.

Here, the hammer 10 pivotally supports the anti-ballistic portion 11 side by a support shaft 12, and between the support shaft 12 and the bullet portion 11, a spring 13 that pulls the ball portion 11 toward the ball hitting standby portion 21. Is provided. A roller pin 14 is rotatably provided on the hammer 10, and a cam 50 rotated by a motor 40 is pressed against the roller pin 14. Hammer
A helical spring is fixed to the ten ball portions 11 in order to efficiently perform the ball shooting. Further, reference numeral 15 in the figure denotes a stopper 15 for maintaining the ball portion 11 of the hammer 10 in the hitting ball standby portion 21.

These components are the same as those of a conventionally used game ball launching device.

However, as shown in FIG. 3, the cam 50 used in the present invention is provided with a spring 13 for firing sequentially according to the direction of rotation.
A load position 51 for extending the ball, a holding position 54 for maintaining the ball section 11 in the direction of the counter hitting standby section 21 in order to hit a ball, and a firing position 52 for hitting the ball 30 of the hit ball waiting section 21. , A load position 51 for retracting the hammer 10 after firing to the maintenance position 54.
And was formed from. Also, here, the load position of the cam 50
On the launch position 52 side of 51, the surface of the load position 51 is
No contact with 14

Such a game ball launching device rotates a motor 40 by means of a launch handle (not shown), and adjusts the resilience of the spring 13 according to the rotation angle of the launch handle, so that the ball reaches the board position aimed by the player. It is a 30 ball.

The movement of the mallet 10 at this time is determined by the shape of the cam 50.

Therefore, when the cam 50 shown in FIG. 2 is used, the ball portion 11 of the hammer 10 is in the hitting ball standby portion 21 immediately after the ball is hit, and at the same time, the rotation of the It is what is being done. Also, at this time, since the cam 50 is configured such that the surface of the load position 51 does not contact the roller pin 14 on the firing position 52 side of the load position 51, the load position 51 faces the roller pin 14 of the hammer 10, and There is no contact.

Next, when the cam 50 is rotated by the rotation of the motor 40, the cam 50 is immediately in the load position 51,
Contacts the roller pin 14, the roller pin 14 is pressed,
The mallet 10 starts swinging about the support shaft 12 so as to oppose the elastic force of the spring 13.

Due to the swing of the mallet 10, the bullet ball portion 11 retreats from the hit ball waiting portion 21.

Also, since the ball 30 to be next shot is replenished to the hitting ball standby unit 21 after the ball is shot, the ball 30 replenished to the hitting ball standby unit 21 retreats from the ball hitting standby unit 21. After that, the ball is supplied to the hit ball waiting unit 21 and is maintained at the lowermost end of the hit ball waiting unit 21.

Then, further rotation of the motor 40 causes the cam 50 to rotate, and the position of the cam 50 in contact with the roller pin 14 changes from the load position 51 to the maintenance position 54.

Due to the time required to change from the load position 51 to the maintaining position 54 due to the rotation of the cam 50, the ball 30 replenished to the hit ball waiting unit 21 stops at the lowermost end of the hit ball waiting unit 21. Becomes

When the motor 40 further rotates in such a state, the cam
The roller pin 14 is disengaged from the cam 50 by the movement of the maintaining position 54 of the 50 to the firing position 52, and the hammer 10 oscillates so that the hammer 10 pushes the ball section 11 toward the ball hitting standby section 21 by the elastic force of the spring 13. I do.

Due to such vibration, the ball portion 11 of the hammer 10 hits the ball 30 of the hit ball standby portion 21.

In such a game ball launching apparatus according to the present embodiment, after the end of the ball, the load portion 51 of the cam 50 promptly changes the ball portion.
By retreating the ball 11 from the hit-ball waiting unit 21, the replenished ball 30 is positioned directly at the lowermost end of the hit-ball waiting unit 21, and the ball 30 stands still in the hit ball waiting unit 21 where the ball is actually hit. Is increased so that even if the number of bullets per unit time increases, stable bullets can be performed.

Further, in the game ball launching apparatus according to this embodiment, since the surface of the load position 51 is not in contact with the roller pin 14 on the launch position 52 side of the load position 51 of the cam 50, the mallet 10 The vibration generated at 15 does not affect the cam 50. However, by providing the surface of the cam 50 so that the vibration can be absorbed to some extent, the cam 50 can be formed so as to be in contact with the roller pin 14 from the beginning at the load position 51.

[Effects of the Invention] As described above, the present invention provides a
The ball in the ball-standby unit where the ball is actually hit is repositioned immediately from the ball-standby unit by immediately retreating the ball unit from the ball-standby unit. The stationary time is increased so that even if the number of bullets per unit time increases, stable bullets can be performed.
