Description

[Detailed description of the invention] The present invention relates to a device that automatically feeds balls one by one to the firing position of the firing rail in conjunction with the firing motion of the hammer arm, and in particular, the present invention relates to a device that automatically feeds balls one by one to the firing position of the firing rail in conjunction with the firing motion of the hammer arm. This invention relates to an automatic ball supply device that enables the ball to be hit.

Conventionally, an automatic ball supply device that enables continuous hitting in conjunction with the firing action of a hammer arm is disclosed in, for example, Utility Model Publication No. 47-2564.
This is already known as described in Publication No. 9.

However, according to this known device, the hammer arm and the ball feed lever that supplies balls are integrally pivotally connected by a rod, so if the rotation angle of the hammer arm is not always constant, balls will not be received accurately. This has the disadvantage that the ball cannot be supplied.

Furthermore, since the balls sent out from the ball feed port are diverted through the route gutter at the back of the machine and supplied to the firing section, it takes time to reach the firing section, making continuous hitting virtually impossible. Not only that, but if you perform the firing operation before the balls have reached the firing part, the balls will be sent out one after another and multiple balls will reach the firing part in a row, which will make the firing operation extremely difficult. Disadvantages have hitherto limited these known devices to practical use.

Therefore, the present invention allows the balls in the ball tray to flow down continuously through the inclined passageway up to the supply port corresponding to the firing position of the firing rail, and by moving the hammer arm to the ball firing preparation position, the ball feeding lever is rotated downward. Then, one ball located at the end of the inclined path is placed on the upper surface of the ball pusher, and the normal feed lever is moved back by the firing action of the hammer arm, and the ball placed on the ball pusher is fired from the supply port through the firing rail. By configuring the ball to be sent to the position, all of the above-mentioned conventional drawbacks are eliminated, and each time the ball at the firing position is fired, the next ball is sent out at the right time, so accurate ball firing can always be expected. , it is possible to make continuous hits that match the firing motion of the hammer arm, which helps speed up the game, and in the case of electric pachinko machines, time intervals that match the rotation of the motor for driving the hammer arm. It was devised to ensure a reliable supply of balls.

Hereinafter, one embodiment of the same will be described with reference to the drawings. 1 is the main body of the Pachinko machine, 2 is a frame-shaped front frame having a window hole that can be opened and closed on the front side, and 3 is a window hole in the front frame 2. This is a game board that is attached to the inner surface, and a launch rail 5 and a guide rail 32 are installed on the surface of the game board.

The tip of the hammer arm 7 faces the firing position 5' of the firing rail 5.

8 is a front decorative plate that covers the lower part of the launch rail 5 and the guide rail 32, and the front frame 2 together with the glass frame 9 that covers the upper part of the game board.
It is hinged so that it can be opened and closed freely.

The front decorative plate 8 is provided with a continuous opening 10, and a sliding ball tray 11 communicating with this opening is fixed to the surface.

The automatic ball supply device a according to the present invention is located on the inner surface of the front decorative plate 8 when the front decorative plate 8 is closed, and is provided in communication between the communication port 10 and the firing position of the firing rail 5.

As shown in FIG. 2, this ball automatic supply device a is mounted vertically on the mounting board 12 at an interval slightly larger than the diameter of the pachinko balls in order to receive the pachinko balls from the communication port 10 and to receive the pachinko balls from the communication port 10. A pair of guide walls 4' are formed in the direction, the part narrowed by the guide walls 4' is the ball inlet 4, and an inclined passage 13 is formed that slopes downward from a position below the ball inlet 4. A supply port 14 corresponding to the firing position 5' of the firing rail 5 is provided at the end of the passage 13, and a mounting board 12 is provided at the end of the passage 13.
A through groove 6 is provided on the bottom surface of the front surface of the supply port 14 at the end of the inclined passage 13, the longitudinal dimension of the inclined passage 13 having a width slightly narrower than the diameter of the pachinko ball.

Reference numeral 15 denotes a ball feed lever which is pivotally connected to the mounting board 12 by a shaft 16, and has an integrally-shaped upper cone piece 17 on the upper surface of the approximately central portion, and in normal state, the cone upper piece 17 faces the through groove 6 from below. It is energized by a weight 18 so as to prevent the ball from flowing down on its side.

Reference numeral 19 denotes a ""-shaped operating lever that is pivotally supported by a fulcrum shaft 20, which is pivotally attached to the lower part of the mounting board 12 or the surface of the game board 3, and which moves a pin 22 protruding from an arm 21 extending laterally to feed the ball. A long hole 2 provided closer to the front end than the shaft 16 of the lever 15
3, and the arm 24 hanging downward is linked to the hooking rod 25 fixed to the hammer arm 7.

Reference numeral 26 denotes a stopper device that is linked to a stopper device (not shown) incorporated in the back structure of the pachinko machine. A shutter plate 29 that allows the entrance 4 to be freely closed is pivotally mounted, a long hole 30 is provided on the lower side of the other arm, and the lower end of a lifting rod 31 of the stopper device is engaged, and the shutter plate 29 is moved upward by the operation of the stopper device. Bell crank 2 by lifting rod 31
8, the shutter plate 29 is pushed to close the ball inlet 4.

The present invention has the above-mentioned configuration, and the ball B of the ball tray 11 is
The ball enters the ball inlet 4 from the communication port 10 and flows into the inclined passage 13, and is stopped from flowing down by the side surface of the ball pusher piece 17 of the ball feed lever 15 just before the supply port 14, as shown by the solid line in FIG. 2, and waits in a continuous state. .

In this state, when the hammer arm 7 is moved to the ball launch preparation position shown by the chain line in FIG. The pin 22 that oscillates and enters the elongated hole 23 of the ball feed lever 15 rotates the ball feed lever 15 downward using the shaft 16 as a fulcrum, thereby lowering the ball pusher upper piece 17 to the end of the inclined passage 13. The ball B1, which has been prevented from flowing down by the side surface of the upper ball pushing piece 17, falls into the through groove 6 and is prevented from being sent out to the single shot firing position by the lower end of the supply port 14.

Then, the hammer arm 7 performs a firing operation and moves back to the position shown by the solid line in FIG. When returning, the ball B2, which had been stopped by the through groove 6 and the lower end of the supply port 14, is sent out from the supply port 14 to the firing position 5' of the firing rail 5 by the ball pusher piece 17, and the above operation is repeated. Balls are automatically fed to the firing position in sequence by the barb.

As will be clear from the above description, according to the present invention, the balls in the ball tray are configured to flow down continuously to the supply port corresponding to the firing position of the firing rail through the inclined passage, so that the configuration is simple and easy. It can be manufactured cheaply.

In addition, the ball is positioned in the through groove at the end of the inclined passage by the operation of the ball feed lever, which rotates downward as the hammer arm moves to the firing preparation position, and moves back by its own weight as the hammer arm fires. Since the balls are sent out one by one to the firing position, the balls can be sent out in synchronization with the firing action of the mallet arm, and compared to the system that feeds the balls by swinging the sub-trough, it is possible to send out the balls one by one to the firing position. It is possible to prevent blank shots and double shots due to the discrepancy between the swinging speed and the firing speed of the hammer arm, and it is also possible to accurately fire pachinko balls one by one regardless of changes in the firing speed of the hammer arm. Effects such as greatly helping speed up the game are produced.

Furthermore, if it is used in a so-called electric pachinko machine that can automatically fire balls by reciprocating the hammer arm as the motor rotates, balls will be reliably delivered at time intervals that match the rotation of the motor. It is possible to provide an automatic ball supply device which has a wide range of applications and has high practical value.

Furthermore, since this device is configured by integrally assembling the necessary related parts to the mounting board, it can be assembled with high precision, and the device can be removed individually, making it compatible for repair, replacement, etc. It is possible to provide an excellent automatic ball feeding device.
