DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as an arrangement ball machine and a sparrow ball machine, and more particularly to an improvement in a lower ball entry device.

[0002]

2. Description of the Related Art Arranged ball machines are used in games.
When a predetermined number of game balls are fired on the upper side of the game board, and the game balls are made to enter any of the 16 ball entrances of the lower ball entry device arranged on the lower side of the game board, The ball detection switch corresponding to the ball entrance detects the game ball and displays the ball entry position of the game ball on the display unit of the display device, and a fixed number of adjacent balls out of the 16 ball entrances. When a winning prize set is established due to a game ball entering the mouth or the like, the game ball is paid out as a prize ball.

Conventionally, in this type of arrangement ball machine, a horizontally long opening is formed in the lower portion of the game board, and a rear mechanism plate side for fixing the game board mounted on the front frame by pressing it from the rear side. When the lower ball entry device is detachably mounted via the joining means, the back mechanism plate is closed and the game board is pressed down, the ball entry case of the lower ball entry device is inserted into the opening of the game board from the rear side. Each of the ball entry cases of the ball entry case protrudes toward the front side of the game board.

In the conventional arrangement ball machine, since the lower ball entry device is located on the back mechanism plate side, there is a problem in changing the game contents by replacing the game board. That is, when performing a so-called exchange for changing game contents in a ball game machine, a method of replacing the entire ball game machine, an outer frame, a front frame, and a back frame attached to the outer frame and the front frame constituting the body of the ball game machine There is a method in which a game board for a pachinko machine and a game board for an arrangement ball machine are exchanged with each other by directly using a mechanism plate or the like.

[0005] However, the lower ball-entering device is indispensable in the arrangement ball machine, whereas the lower ball-injection device is not necessary in the pachinko machine. Therefore, when changing from the arrangement ball machine to the pachinko machine, While exchanging the game board,
It is necessary to remove the lower ball entry device from the back mechanism plate. Therefore, conventionally, it is very difficult to replace the game boards of a large number of ball game machines in a short time.

In particular, since the lower ball entry device is detachably attached to the back mechanism plate via the engagement means, there is a possibility that the engagement claw may be broken during the replacement operation. For this reason, it is necessary to carefully attach and detach the lower ball entry device side, and there is a drawback that the work efficiency is remarkably reduced, and this exchange work becomes a major bottleneck when exchanging game boards and changing game contents. ing.

In the game board, a large number of obstacle nails are arranged near the upper side of the opening where the lower ball entry device is fitted so as to correspond to each entrance of the lower ball entry device. Since the lower ball entry device is detachably attached to the back mechanism plate that is detachably attached to the front frame and that is pivotally attached to the front frame so as to be openable and closable, each entry port of the lower ball entry device, There is a drawback that the positional deviation between the nail and the obstacle corresponding to the entrance is likely to occur, and a large difference occurs between individual arrangement ball machines.

Conventionally, since the lower ball input device is located on the back mechanism plate side, the game board side and the lower ball input device are closely related to each other, but each game component is mounted on the game panel to form a game panel unit. After assembling, when inspecting the electrical system of each game component, each ball entry detection switch of the lower ball entry device cannot be inspected at the same time, and the lower ball entry device side needs to be performed in a separate inspection process. is there. The present invention has been made in view of the above-described conventional problems, and allows a game board and a lower ball entry device to be attached and detached together, thereby efficiently and easily performing an exchange operation when exchanging game boards and changing game contents. It is another object of the present invention to provide a ball game machine which can reduce the displacement between each ball entrance and an obstacle nail and can simultaneously inspect the lower ball entry device side when inspecting a game component on the game board side.

When a game ball enters the game ball 34, the game ball passes through the inside of the ball entrance 34 and moves to the back side of the game board 6, and from the rear end of the ball entrance 34, the detection hole of the ball entry detection switch 39 is formed. After passing through 39a, it falls downward through the space between the game board 6 and the rear wall 54 of the entry case 36. Then, the game ball is detected by the detection hole 39a of the ball detection switch 39.
When the ball passes, the ball entry detection switch 39 detects a game ball and the display unit 42 corresponding to the ball entry position displays a numeric symbol.

When the lower ball entry device 16 fails, the back mechanism plate 25 is opened, the game board 6 is removed, and the back cover 24 is removed. Remove and replace. However, when some of the ball detection switches 39 fail, the ball detection switches 39 are individually replaced.

In this case, first, the glass door 4 is opened and the lower cover 17 is removed from the game board 6. Next, after the flat cable 75 is detached from the connection connector 73, the pair of left and right elastic locking pieces 49 of the ball entry case 36 are bent outward to release the engagement with the support member 38, and then the support member 38 is brought forward. Pull out. Then, the switch board 41 and the ball entry detection switch 39 are separated from the ball entry case 36 together with the support member 38. Therefore, of the 16 ball entry detection switches 39 inserted into the switch holding holes 72 of the support member 38, a failure occurs. It is sufficient to remove only the incoming ball detection switch 39 and insert another incoming ball detection switch 39.

Accordingly, the support member 38, the switch board 41, and each of the ball entry detection switches 39 can be easily removed from the ball entry case 36 while being integrated. Further, after removing each ball detection switch 39 from the ball case 36 on the game board 6 in a state in which the ball detection switch 39 is integrated with the support member 38, the ball detection switch 39 can be replaced. The replacement work can be easily performed without bothering. In particular, since the support member 38 is removed from the front side of the game board 6, there is no need to remove the ball entry case 36, the ball collection case 37, and the like, and the support member 38 can be easily removed.

Even when the ball entry detection switch 39 is detached from the ball entry case 36, each ball entry detection switch 39 is connected to the switch board 41 while being inserted and held in the switch holding hole 72 of the support member 38. When the detection switch 39 is detached, an unexpected external force does not greatly act on the other incoming ball detection switches 39.

When the ball entry detection switch 39 is mounted, the ball entry detection switch is inserted into the switch holding hole 72 of the support member 38.
If the ball 39 is inserted and pushed in, the ball detection switch 39 is connected to the switch board 41 via the connector 40, so that the ball detection switch 39 can be easily and reliably connected.

When the support member 38 is mounted in the support member mounting hole 44 of the ball entry case 36, the support member 38 is brought into contact between the elastic locking pieces 49 on the ball entry case 36 side and is pushed in rearward. Since each elastic locking piece 49 is elastically deformed and expanded outward by the support member 38, the support member 38 can be easily inserted and mounted in the support member mounting hole 44. After that, the lower cover 17 may be attached.

Each of the ball detection switches 39 is arranged in two upper and lower rows, and the ball detection switch 39 of the lower row is arranged at the approximate center between adjacent ball detection switches 39 of the upper row. So that the width of each ball detection switch 39 is
Despite being larger than the pitch between the lower ball input device 16 and the lower ball input device 16 by arranging the ball input detection switch 39 in the upper row and the ball input detection switch 39 in the lower row in an overlapping manner. Left and right width can be reduced.

When changing the game content from the arrangement ball machine to the pachinko machine by replacing the game board 6, the front frame 3 is opened forward, and the fixing of the back mechanism plate 25 by the lock lever is released. The mechanism plate 25 is opened rearward. Then, after removing the game board 6 for the arrangement ball machine from the front frame 3, the game board 6 for the pachinko machine is fitted and the back mechanism board is inserted.
Hold with 25 and fix.
