Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to fire the balls one by one from the ball tray by linking them with the firing motion of the ball rod, which is installed on the front of the front panel of the pachinko machine. This invention relates to a ball supply device for a pachinko machine that feeds balls to a position.

[Prior art] As this type of ball supply device, for example, Jikkosho's
As shown in Japanese Patent Application No. 58-4528 (hereinafter referred to as Conventional Example 1), the balls in the ball tray are continuously flowed down through a long inclined path to the supply port corresponding to the firing position of the firing rail.

Also, Japanese Patent Publication No. 50-18422 (hereinafter referred to as conventional example 2)
That's what it means. ) As shown in the figure above, the gear has a plurality of semicircular notches on its outer periphery that are rotated at low speed by a motor or the like and receive one pachinko ball above the lower end of the guide gutter that extends from the ball tray and guides the balls inside in a line. , an arcuate frame is provided along the rotational direction of the gear, and a reservoir is provided at the discharge port thereof, and an opening/closing mechanism that opens and closes by operating a firing lever is exposed at the lower end of the reservoir. A guide gutter is provided between the guide rail and the firing position via a fixed blocking piece, and the balls accumulated in the reservoir are supplied to the firing position each time the firing lever is operated.

Furthermore, as shown in Japanese Utility Model Application Publication No. 59-64179 (hereinafter referred to as Conventional Example 3), rotation can be achieved by exciting an electromagnet between the introduction path connected to the ball receiving tray and the ball delivery hole to the ball part. There is a structure that includes a ball sending body that moves the balls in the introduction path and feeds the balls one by one to the delivery hole.

[Problems to be solved by the invention] Conventional Example 1 has a long inclined path, making the entire device large and requiring a large installation space, and the ball is sent to the firing position in synchronization with the firing operation of the ball rod. Therefore, the first firing operation of the batting rod always ended up being a blank firing, resulting in wasted operation.

In addition, in Conventional Example 2, the ball is supplied to the firing position by a rotating gear, so the space can be reduced by that amount, but since a prime mover such as a motor to drive the gear is required, the overall device becomes larger. This is undeniable, and if there are a series of balls at the bottom of the outlet gutter, the gear will rotate in the opposite direction to the flow of the balls and scoop them up, which can easily cause malfunctions and put a huge load on the prime mover, which can lead to breakdowns. becomes. Furthermore, when the firing lever is pulled, the first shot is stopped by the end-fixing blocking piece through the opening/closing mechanism, and when the ball is fired, it is guided to the guide gutter and then supplied to the firing position, so the first firing operation is always a blank shot as described above. This causes waste in the final operation.

Furthermore, in Conventional Example 3, the ball throwing body is rotated by switching the power supply of the electromagnet and the balls are fed to the firing position one by one, so the problem of blank shots may be solved, but the problem of using an electromagnet is The entire device becomes large and requires a large installation space. Also,
There is a problem in that it is necessary to adjust the timing between the operation of the firing lever that fires the ball and the supply of the ball, and it is difficult to make this adjustment.

[Means for Solving the Problems] Therefore, the feeding device of the present invention was created in view of the above problems, and includes a plurality of pins projecting at equal intervals along the same circumference of the surface, and one pin on the outer periphery. A ball feeder is formed by providing the same number of ball receiving recesses as the number of pins, and the ball feeder is pivotally supported on a base plate so as to rotate intermittently only in one direction. An arc-shaped guide wall surrounding a part of the outer periphery of the ball feeding machine to form a ball passage is provided on the base plate, and a ball inlet communicating with the ball receiving tray is provided at the upper end of the passage, and a launching rail is provided at the lower end. A supply port is provided at the front upper part of the firing position, and an interlocking lever is arranged which is interlocked with the ball hitting rod and pushes the pin when the ball hitting rod is pulled, and the ball feeder always has one ball. The ball receiving recess is aligned with the ball inlet to receive the balls, and the ball feeder is rotated one pitch at a time via the interlocking lever that pushes the pin when the ball rod is pulled, and the balls in the ball receiving recess are sent from the supply port. The configuration is such that it is sent to the firing position.

[Operation] The balls in the ball tray pass from the outlet to the ball inlet and fit into the ball tray recess of the ball feeder. Then, when the ball rod is pulled and moved to the firing preparation position, the interlocking lever is pulled along with this action, and its tip pushes the pin of the ball feeder, causing the ball feeder to rotate one pitch and move into the ball receiver recess. The ball is supported by the guide wall and moved down the passage, and sent out from the supply port to the firing position of the firing rail.

In this state, the traction on the ball rod is released to perform a firing operation, and when the ball rod returns to its original position, the interlocking lever also returns to its original position.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a pachinko machine main body, 2 is a front frame thereof, and 3 is a game board located at the rear of the front frame 2, on the surface of which a firing rail 4 and a guide rail 5 are installed.

Therefore, the hit ball supply device according to the present invention has a second
As shown in the figure and FIG. 3, a base plate 12 made of synthetic resin
The base plate 12 is fixed to the rear surface of the front plate 8 by screws 13. A support shaft 14 is fixed to the base plate 12, and a ball feeder 15 is pivotally supported on the support shaft 14. The ball feeding machine 15 has five pins 16 protruding at equal intervals along the same circumference on the surface, and a pin 1 on the outer periphery.
It is configured by providing ball receiving recesses 17 having the same number as 6 and having a depth enough to fit one hit ball. Five serrated engagement teeth 18 and 19 having a vertical surface and an inclined surface are carved radially from the center on the back surface of the ball feeder 15 and the surface of the base plate 12. The ball feeder 15 is constantly pressed against the base plate 12 by the coil spring 20 so that the engaging teeth 18 and 19 are engaged with each other, thereby moving the ball feeder 15 only in one direction, that is, clockwise in FIG. It rotates intermittently.

Further, an arc-shaped guide wall 22 is provided integrally with the base plate 12 so as to surround a part of the outer periphery of the ball feeder 15 and form a ball passage 21. A ball inlet 23 is formed to coincide with the outlet 11 of the front plate 8 and introduce the balls from the ball catch tray 10 into the ball catch recess 17 of the ball feeder 15.
A supply port 24 located at the upper front of the firing position 6 of the firing rail 4 is formed at the lower end of the firing rail 4 . The ball feeder 15 is rotated intermittently by 1/5 by the engaging teeth 18 and 19, and always stops at a position where one of the ball receiving recesses 17 matches the ball inlet 23.

Reference numeral 25 denotes an interlocking lever that is pivoted to the surface of the lower part of the game board 3 by a shaft 26, and has an arm 25a bent upward in a dogleg shape at the tip, and a pin 16 of the ball feeder 15 at the upper end. A feed pawl 27 that can be pushed in contact with the feed pawl 27 is swingably supported by a shaft 28. Further, the interlocking lever 25 has an arm 25b hanging downward near the rear end thereof, and the arm 25b is linked to a hooking rod 29 fixed to the hitting rod 7. Incidentally, the interlocking lever 25 is made heavier at the tip side, and is held at the solid line position in FIG. 5 with the upper surface of the rear end abutting against the stopper piece 30. 31 is a stopper for the feed claw 27.

The present invention consists of the above-mentioned configuration, and includes a ball tray 1
The hit ball B at the end lined up at 0 passes from the outlet 11 to the ball inlet 23 and fits into the ball receiver recesses 17, 17a of the ball feeder 15, as shown by the solid line in FIGS. 4 and 5, and is held in that position. . In this state, the ball feeder 15 is prevented from rotating by being pressed by the coil spring 20. Then, when the hitting rod 7 is pulled and moved to the firing preparation position as shown by the chain line in FIG. is axis 2

6a and pushes it against the coil spring 20. As a result, the ball feeder 15 is allowed to rotate clockwise as the engaging teeth 18 of the ball feeder 15 slide on the inclined surface of the engaging teeth 19 of the base plate 12, and the angle of one pitch of the pin 16, i.e. After 1/5 rotation, the engaging tooth 18 is engaged again.
19 is engaged and its rotation is prevented. As this ball feeder 15 rotates, the ball receiver recess 17,
The hit ball B of 17a moves downward through the passage 21 while being supported by the guide wall 22, and is sent out from the supply port 24 to the firing position 6 of the firing rail 4, and at the same time, the next hit ball B is
_B1 is fitted into the ball socket recesses 17, 17b and held.

In this state, when the hitting rod 7 is released from the traction and the firing operation is performed, and the hitting rod 7 returns to its original position as shown by the solid line in Figure 5, the interlocking lever 25 also lowers its tip under its own weight and returns to the original solid line position. Return. At this time, feed claw 27
The ball slides on the pins 16, 16b and returns to its original position, and by repeating the above operation, the ball is supplied to the firing position.

[Effects of the invention] As described above, the ball supply device of the present invention includes a ball feeder provided between the ball inlet connected to the ball tray and the supply port to the firing position, and an interlocking lever that interlocks with the ball rod. Since the ball feeder is rotated, the structure is simple, and since there is no need for a long passage, a motor, etc., the entire device can be made smaller. Additionally, the cost can be lower than that using a drive source such as a motor.

Furthermore, the ball feeder is prevented from reversing by rotating intermittently in one direction only by the interlocking lever, and is hardly subjected to ball pressure from other balls in the ball tray, so the ball can be sent out smoothly and reliably. Moreover, compared to systems that use electromagnets to supply balls independently, there is no need to adjust the timing with the movement of the ball rod. Furthermore, since the ball is sent to the firing position in synchronization with the firing preparation motion of the batting rod, wasteful movements such as dry firing are eliminated, and the ball is reliably hit in accordance with the firing motion of the batting rod from the beginning. Balls can be fired without causing discomfort to players.
