DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mechanical plate of a pachinko machine which is attached to the back of a game board so as to be freely opened and closed.

[0002]

2. Description of the Related Art Conventionally, as is well known, a game board of a pachinko machine is provided with a mechanism plate in which a series of back mechanisms such as a ball tank, a pachinko ball dispensing device, and a winning ball discharging section are assembled so as to be freely opened and closed. . The mechanical plate of this conventional pachinko machine has a winning ball gathering portion formed on the front side opposite to the back surface of the game board, and forms an opening concave portion in a portion located below the winning ball gathering portion, and has the opening A prize ball discharge unit collectively installed on one device plate in the recess is mounted from the front side of the mechanism plate and is detachably screwed. And a pachinko ball discharge passage for guiding the pachinko balls dispensed from the pachinko ball dispensing device to the hitting ball supply tray on the front of the pachinko machine, and an excess ball discharging passage for discharging the surplus balls of the hitting ball supply tray to the lower ball tray on the front of the pachinko machine. Are connected to each other by a passage member formed separately from the mechanism plate, and the passage member is screwed to the winning ball discharge processing device.

[0003]

However, in the conventional mechanical plate of this type of pachinko machine, a passage member formed separately from the mechanical plate is directly fixed to a winning ball discharging portion by a screw and fixed. Therefore, there is a problem that it takes a lot of time to remove the winning ball discharging portion from the front side of the mechanism plate and repair or replace parts. That is, in order to remove the winning ball discharge portion from the mechanism plate, first remove the mounting screw of the cover that covers the front portion of the pachinko ball discharge passage and the surplus ball discharge passage, remove the cover from the mechanism plate, and then remove the passage member. It is necessary to remove the mounting screws and remove the passage member from the mechanism plate. In particular, since the cover is usually fixed to the mechanism plate with a plurality of screws, the operation of removing these screws is very complicated. It was troublesome and time-consuming. In addition, even if the cover is removed, the passage member is attached so as to close the rear surface of the prize ball discharge section, so that the prize ball discharge section cannot be visually recognized. The stopped passage member had to be removed. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a mechanism plate for a pachinko machine capable of easily removing a winning ball discharging portion from the mechanism plate. It is intended to provide.

[0004]

In order to achieve the above object, the present invention relates to a mechanical plate of a pachinko machine provided on a back surface of a game board, wherein the mechanical plate has a front surface opposed to the back surface of the game board. A winning ball collecting portion is formed on the side, a ball tank is provided on the rear side of the mechanism plate, a lead-out gutter for guiding the pachinko balls of the ball tank to a pachinko ball dispensing device, and a pachinko ball dispensed from the pachinko ball dispensing device. The pachinko ball discharge passage leading to the front hitting ball supply tray, the pachinko ball discharging passage through a passage member formed separately from the mechanism plate, and the surplus balls of the hitting ball supply tray are transferred to the lower ball receiving tray on the front of the pachinko machine. A surplus ball discharge passage for flowing out is provided, and an opening recess is formed in a portion of the mechanism plate located below the winning ball collecting portion, and the winning ball discharge unitized in the opening recess is formed. Is the front side of the mechanism plate Is mounted, further wherein the passage member is positioned on the rear surface of the winning ball discharge unit, and characterized in that it is mounted fixed to the inside surface of the cover which covers the pachinko ball discharge passage and the surplus ball discharge passage portion.

[0005]

According to the present invention, the passage member formed separately from the mechanism plate is attached to the inner surface of the cover that covers the pachinko ball discharge passage and the surplus ball discharge passage. As a result, when removing the winning ball discharge part from the mechanism plate and repairing or replacing parts, it is necessary to simply remove the screw fixing the winning ball discharge part from the front side of the mechanism plate and connect it to the passage member. In addition, only the winning ball discharge portion can be easily removed from the mechanism plate. Further, when the cover is removed, the passage member located on the rear surface of the winning ball processing unit is also removed, so that the winning ball discharging unit can be visually recognized only by removing the cover, and the inspection operation can be easily performed.
