Description

[Detailed description of the invention] This invention relates to the improvement of the ball extracting device in the prize ball tray of a pachinko machine. To provide a ball picking device for a prize ball tray, which facilitates the ball picking operation by pressing down a push button provided at a proper place.

In conventional pachinko machines, the ball extraction device for the prize ball tray is usually equipped with a slide-type opening/closing plate in the ball extraction hole, and by sliding the operation button on the tray, the opening/closing plate opens and closes and balls are extracted. However, this has drawbacks such as the need to hold the button horizontally with your finger when opening the hole, making it difficult to operate, and the sliding surface of the operation button being exposed to the front of the saucer, making it difficult to mount the button on the body. It was hot.

This invention was devised to eliminate the above-mentioned drawbacks, and will be explained below based on the embodiments shown in the drawings.

In FIGS. 1 to 4, 1 is a prize ball receiving tray, and a ball releasing hole 4 is bored in the ball supply passage 3 of the receiving tray plate 2, and the ball removing hole 4 is opened and closed on the lower surface of the receiving tray plate 2. The rear end of an opening/closing rod 6 having a ball receiving plate 5 at its tip is rotatably supported by a shaft 7, and a return spring 8 is provided between the rear end 13 of the opening/closing rod 6 and a saucer plate, etc. The opening/closing rod 6 is always urged in the closing direction to return the ball receiving plate 5 to the ball removing hole 4 and close it.

Reference numeral 9 denotes a push button which is provided at a suitable position on the upper part of the ball receiving tray plate 2 so as to be able to freely slide up and down, so that it can always return upwardly with a return spring 10, and an operating rod 11 formed integrally with the push button 9 is provided with an inclined cam 12. , this is the saucer plate 2
When the push button 9 is pressed down, the opening and closing rod 6 is pushed open by the inclined surface of the inclined cam 12, and the ball receiving plate 5 is rotated in the horizontal direction from the ball removal hole 4. Then, the ball removal hole 4 is opened and the ball removal is performed.

The structure of the ball receiving tray 1 shown in the embodiment is a receiving tray plate 2 in which a ball guide wall 15 and a ball supply passage 3 are formed on the mounting plate 14 side.
A ball supply port 17 from the ball supply passage 3 to the ball supply device is bored in the mounting plate 14, and a ball guide wall of the saucer plate 2 is provided. A discharge passage 18 for discharging balls from the ball removal hole 4 is provided at the lower part of the opening/closing rod 6, a housing 19 is provided on the lower surface of the receiving tray plate 2, and a ball receiving plate 5 is formed in an L shape at the tip of the opening/closing rod 6. The side is pivoted freely to rotate 7,
A return spring 8 is interposed between the rear end 13 of the opening/closing rod 6 and the housing 19 to urge the tip of the opening/closing rod 6 in the closing direction, and the ball receiving plate 5 is positioned in the ball removal hole 4. An operating rod 11 is provided at the lower part of the push button 9, and an inclined cam 12 is formed on the lower front side of the operating rod 11, and the push button 9 is inserted into a recess 20 bored in the upper part of the ball guide wall 15 so as to be freely slidable up and down. , the operating rod 11 is projected downward through the insertion hole 21 of the ball guide wall 15 and the insertion hole 22 of the saucer plate 2, and the inclined cam 12 is inserted into the recess 2 of the opening/closing rod 6.
3, and a return spring 10 is inserted between the step portion 24 on the rear side of the operating rod 11 and the saucer plate 2 to urge the operating rod 11 upward. Therefore, the push button 9 is always located upward, and at this time, the ball receiving plate 5 closes the ball removal hole 4, and when the push button 9 is pressed down, the inclined cam 12 moves the tip side of the opening/closing rod 6 inward. It rotates further outward about the extrusion shaft 7 as shown in FIG. 3. In addition, a space 25 is provided on the side of the saucer front frame 16 in which the opening/closing rod 6 rotates, and a ball guide plate 26 located at the end of the ball supply passage 3 is provided so that when the opening/closing rod 6 is rotated, the ball receiving plate 5 is rotated. It is designed to fit under the ball guide plate 26.

Since this invention has the above-mentioned configuration, when the prize balls are lined up from the ball supply passage 3 of the prize ball tray 1 to the hit ball supply device, the push button 9 is pressed to remove the balls.
By pressing down with a finger against the return spring 10, the opening/closing rod 6 is rotated by the inclined cam 12 against the return spring 8 to open the ball removal hole 4 and remove the ball.
By releasing the pressure on the push button, the opening/closing rod 6 and the push button 9 are returned to their original positions by the return springs 8 and 10, and the ball receiving plate 5 closes the ball removal hole 4.

According to this invention described above, when the push button is pressed down, the opening/closing rod is pushed forward by the action of the inclined cam of the operating rod, and the ball receiving plate at the tip is removed forward from the position of the ball removing hole, thereby opening the ball removing hole. Since it can be completely opened, the balls in the ball supply passage can be dropped directly below and discharged without getting stuck.
Moreover, since there is only a push button on the front, it has practical benefits such as good appearance and the ability to improve the product value.
