Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a back mechanism on the back of a pachinko game board.

[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 plate to the lower ball tray on the front of the pachinko machine. And a passage member formed separately from the mechanism plate, and the passage member is screwed to the winning ball discharge portion.

[0003]

However, the mechanical plate of this type of pachinko machine having a series of back mechanisms conventionally used is provided with a prize ball formed by a passage member formed separately from the mechanical plate. Since the prize ball discharge portion is directly fixed to the discharge portion with a screw, there is a problem that it takes a lot of trouble to remove the prize ball discharge portion from the front side of the mechanism plate to 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. Also,
For example, when a passage is provided on the rear side of a device such as a winning ball discharge unit, the device can be visually recognized because the passage is located so as to close the device even if the cover is removed. Inconvenience in inspection work. Further, when the passage is provided in the back mechanism provided with various devices, there is a layout problem that a space for arranging the passage must be considered in consideration of the relationship with the device. SUMMARY OF THE INVENTION 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 back mechanism of a pachinko machine capable of easily removing a winning ball discharging portion from a mechanism plate. It is intended to provide.

[0004]

In order to achieve the above object, the present invention relates to a back mechanism for a back surface of a game board, wherein the back mechanism includes various devices such as a pachinko ball payout device and a pachinko ball payout device. A pachinko ball discharge passage for guiding the pachinko balls dispensed from the device to the hitting ball supply tray, a surplus ball discharging passage for discharging the surplus balls of the hitting ball supply tray to the lower storage dish, and various other paths, and any of the various paths constituting the above various paths. The passage is formed by a passage member separate from the back mechanism, and the passage member is attached and fixed to a cover covering various passage portions.

[0005]

According to the present invention, the passage member formed separately from the back mechanism of the pachinko machine is attached to the cover which covers various passage portions such as the pachinko ball discharge passage and the surplus ball discharge passage.
As a result, when the winning ball discharge unit is disposed on the mechanism plate as one form of the back mechanism, when the winning ball discharge unit is removed from the mechanism plate to repair or replace parts, the winning ball discharge unit is disposed from the front side of the mechanism plate. By simply removing the locking member fixing the winning ball discharge portion, only the winning ball discharging portion can be easily removed from the mechanism plate regardless of the passage member. In addition, when the cover is removed, the passage member is also removed at the same time.For example, when a passage is provided on the rear side of the device such as a winning ball discharge unit, the device can be visually recognized only by removing the cover, Inspection work can be performed easily. Further, since the passage member can be attached to the cover side, there is no need to consider a space for disposing the passage in the back mechanism provided with various devices, and the various devices can be freely arranged.
