2. Description of the Related Art Generally, the front frame of a pachinko machine is
It is equipped with an electrically operated device such as a jackpot indicator lamp and a drive motor for the launcher. Also, on the game board, in addition to the out-of-ball lamp of the prize ball tank and the prize ball lamp, it is possible to electrically change the display state and a large variable winning device that is electrically driven and controlled to facilitate winning the game ball. An electric operating device such as a variable display is mounted, and a board box containing a circuit board for driving and controlling the various electric operating devices described above is mounted on the back surface of the game board. In connection with this, the mechanism plate is equipped with a terminal box to which a plurality of wires drawn from various electrically operated devices provided on the front frame and the game board are connected via connectors.
The terminal box 101 is, for example, as shown in FIG. 7, formed in a substantially box shape in which the peripheral side edge of the front plate 102 is surrounded by a side frame 103 and the rear surface is opened 104, and the various electrical devices mounted on the back surface of the game board. The wiring board 105 for connecting the wiring drawn out from the operating equipment is internally provided. More specifically, the fixing frame 106 for fixing various connection terminals of the wiring board 105 is provided with screw holes 107, 107, while the front plate 102 of the terminal box 101 is provided with the screw holes 10.
The same number of through holes 108 are provided at positions corresponding to 7, 107, the wiring board 105 is pressed into the terminal box 101 from the rear opening 104, and the screws 109 are respectively screwed into the screw holes 106 through the through holes 108. Then, the wiring board 105 is assembled to the terminal box 101 by screwing.

[0003]

As described above, since the terminal box 101 in the conventional pachinko machine is mounted by screwing the wiring board 105, the assembling work is troublesome, and a lot of labor is required. It took time and was a hindrance to improving work efficiency. Also, in the replacement work when the terminal box 101, that is, the wiring board 105 is replaced due to failure or the like, the screws 109 are loosened one by one and removed from the terminal box 101, which is a problem that the work is troublesome. there were. Therefore, the present invention has been made in view of the above problems, and an object of the present invention is not to provide a terminal box for a pachinko machine that enables easy assembly or replacement work of a wiring board in the terminal box in a short time. It is what

[0004]

In order to achieve such an object, a terminal box in a pachinko machine of the present invention is formed in a substantially box shape in which a peripheral side edge of a front plate is surrounded by a side frame and a rear surface is opened. In a terminal box containing a wiring board for connecting wiring drawn from various electrically operated devices mounted on the back side, a projection is provided on the inner side surface of the side frame, and the wiring board is locked by the projection. By doing so, it was attached to the terminal box.

[0005]

[Function] A wiring board is pressed against the rear opening of a terminal box formed in a substantially box shape with a rear opening, and the outer peripheral edge is locked by a protrusion provided on the inner surface of the side frame of the terminal box. By doing so, the wiring board is assembled in the terminal box.
