Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, and more particularly to a game machine in which a ball passage member forming a passage for a game ball is grounded by being attached to a device body.

[0002]

2. Description of the Related Art A game machine such as a pachinko machine has an inner frame openably and closably attached to an outer frame which constitutes an outer shell of a device body and is installed in an island facility. A board, a glass frame, a ball hitting tray, a firing handle, etc. are arranged, and a back set (mechanical frame) equipped with an upper tank and a lower tank for storing prize balls and a prize ball dispensing device is attached to the back surface of the inner frame. Has been. In recent years, this back set is made of a conductive resin material, and is grounded (grounded) to the GND terminal of the island facility via a lead wire, etc., and a ball such as a game board or a hitting ball supply plate that forms a passage for the game ball. By connecting the passage member to the back set using a conducting wire (ground wire), static electricity charged in the ball passage member due to contact and friction of the game balls is eliminated to the back set side.

On the other hand, recently, a so-called "left hitting" is performed in which a hitting ball launching device is arranged at the lower left of the game board to shoot the hitting ball upward.
The so-called model is being developed. In the case of this model, the batting ball launcher installed in the inner frame of the conventional model and located at the lower right of the game board, and the batting ball located almost directly below the game board are guided diagonally upward to the left and the gaming board side Since there is no need for a guide rail or the like leading to, there is an advantage that it is easy to expand the game area by utilizing the empty space created on the lower side of the game board (improvement of game play).

Along with this, the hitting ball supply tray (upper tray) and the surplus ball receiving tray (lower tray), which are conventionally divided into two, are constructed as an integral tray having the functions of both, and the height of the conventional upper tray is reduced. The same as or higher than the conventional storage by placing the ball storage member (ball storage tank) that stores the game balls that cannot be stored in the ball tray part of the integrated plate on the back side of the integrated plate Many changes have been made such that the amount can be secured (for example, see Patent Document 1).

However, in the conventional construction in which the ball passage member is grounded via the back set, the work of connecting the ground wire for conducting the ball passage member to the back set is complicated, and further, However, there is a problem that workability when the ball passage member is detached for maintenance or the like is deteriorated.
Further, in the configuration shown in Patent Document 1, the sphere storage member also
Since the game balls need to be grounded for contact, and thus the new model described above may increase the number of ground connection points, it is strongly desired to improve the connection workability.

In view of the above facts, an object of the present invention is to provide a gaming machine in which the ball passage member forming the passage of the game ball has a good ground connection workability.

76, the convex portion 198), and the outer band 36 and the inner band 37 which are passage portions of the game ball and the tank bottom surface 25D of the ball storage tank 25, the back set 1 via the conduction plate 170.
It is electrically connected to 20 and is grounded. Further, the upper wall portion 186 of the conduction plate 170, the inclined plate 188, the inclined surface portion 19
0 is also a passage part of the game ball, and these parts are also electrically connected to the back set 120 and grounded. In this way, the game board 32, the ball storage tank 25, the conduction plate 170
By simply attaching the to the inner frame 14, the passage portion of the game ball can be easily grounded, and therefore the workability of grounding is improved.

Further, in the present embodiment, the spring members (the leaf springs 194A and 194B and the conduction spring 16) are used to connect the respective members.
The use of 8) ensures the conduction of each connecting portion, and further simplifies the configuration.

Further, in this embodiment, the locking device 22 attached to the inner frame 14 is grounded, and the ball feeding device 112 on the side of the integrated plate 26 is reinforced by the ground wire 114.
When the integrated dish 26 is closed to the inner frame 14 by conducting the electrical connection to the rectangular plate 108A, 108B of the reinforcing plate 106 engages with the hooks 110A, 110B of the locking device 22, and the integrated dish 2 is closed.
6 is locked in the closed state, the reinforcing plate 106 and the locking device 22 are electrically connected, and the ball feeding device 112 is grounded to the outside. Therefore, between the inner frame 14 and the integrated plate 26, a simple connecting structure can be provided in which the conducting wire or the like is omitted when the ball feeding device 112 is grounded.

In the above-mentioned embodiment, the metal spring member is used to bring the parts into conduction by pressure contact.
Besides, it can be replaced with an elastic member made of a conductive resin material such as conductive rubber. Further, regarding the ground connection of the electric components between the inner frame 14 and the integrated plate 26, the glass frame 20 in the pachinko machine 10 of the present embodiment.
Alternatively, it can be applied to the plate of the conventional model. For example, in the case of the glass frame 20, by connecting the substrates 67A to 67G and the like to the reinforcing plate 100 with a ground wire as necessary,
It can be easily realized.
