Next, the operation and effect of the embodiment having the above-mentioned structure will be described. The pachinko machine described above
In trick ball detection apparatus U, a plurality of balls receptacle 29 arranged in a row along the game board 7a, and the bottom of Tama受case 11 removably attached to the game board 7, each A plurality of game ball detection switches 21 to 21 arranged in a plurality of rows in the horizontal direction in a state where the detection ports 21a are respectively positioned immediately below the ball reception ports 29 , and their mounting positions are shifted in a staggered manner. in attached removably individually.

Further, the rear end of Tama受case 11, a plurality of distribution connectors 34-34 which are connected to each gaming ball detection switch 21 are respectively installed above each of the gaming ball detection switch 21, the game Collective connector 35, 35 for collecting detection signals of the ball detection switch 21 and communicating with the outside
Is mounted on the printed circuit board 33 .

Further, the ball receiving case 11 has electric exposed portions of the game ball detecting switches 21 and distribution connectors 34 to 3.
4. Collective connectors 35 , 35 , and printed circuit board 33
The cover 44 is attached with the
I have .

From this , each game ball detection switch 21
Can be individually removed from the ball receiving case 11,
Only the required game ball detection switch 21 can be removed and replaced and repaired, and the handling, replacement work, and repair work of each game ball detection switch 21 can be simplified.

Further, a plurality of rows of game ball detection switches 21 are arranged laterally with their mounting positions being staggered, and each of the distribution connectors 34 to 34 is connected to the game ball detection switch 2.
Respectively placed in one of the upper, the gaming ball detection switch 2
Since 1 and each distribution connector 34 are connected, each game ball detection switch 21 avoids mutual interference and each detection port 2
1a can be installed in the compact while being positioned directly below the ball receiving port 29, respectively .

Further , each game ball detection switch 21 and each distribution connector 34 can be arranged at a minimum interval, and can be connected neatly with a lead wire of a minimum length. Can simplify and neatly arrange the wiring state of the lead wires connected to the terminals.

The adjacent game ball detection switches 21 and
Since a gap is formed between 21, the removal and replacement of each game ball detection switch 21 can be smoothly performed without being obstructed by the adjacent game ball detection switch 21.

In particular, in the case of this example, the ball receiving ports 29 to 29
Single ball detection switches 21 to 21 and printed circuit board 33
Unitized into a ball receiving case 11 (case body)
Runode, it can be handled as the assembly of ball receiving case 11 integrally, in this regard it is possible to improve the handling property.

A plurality of balls are provided on the front of the ball receiving case 11.
While the receiving ports 29 to 29 are provided in a row,
On the back of the case 11, a plurality of game ball detection switches 21 to
21 and the respective distribution connectors 34 to 34 of the printed circuit board 33.
It is configured to correspond to each ball socket 29-29
So, the arrangement game type pachinko machine illustrated
Ball receptacles 29 to 29 arranged in a row
In contrast, the game ball detection switches 21 and 2
1 and the distribution connectors 34 to 34 can be arranged neatly.
Assembly work of the game ball detecting device U or its maintainer
This makes it possible to efficiently perform the sensing work.

In the case of this configuration, the game ball detection switch 21
To 21 and the distribution connectors 34 to 34 are connected to the respective ball sockets 29 to
29 corresponding to each game ball detection switch.
Switches 21 to 21 and distribution connectors 34 to
34 is arranged at a position close to the
Can be connected with the same lead wire.
Greatly simplifies and neatly sorts the wiring structure of
it can. Also, the game ball detection switches 21 to 21 and this
Distribution connector to be connected or connected
Since the relationship with 34-34 can be understood at a glance,
Maintenance work and the like can be performed efficiently.

In addition, the above-described wiring structure known in the art (Japanese Patent Laid-Open Publication No.
(Wiring structure disclosed in JP-A-62-139681)
Connects which distribution connector to which game ball detection switch
To be able to identify whether or not
It is necessary to keep the wiring of the illustrated game ball detection device U
According to the configuration, the game ball detection switch 21 should be connected.
Since the distribution connector 34 is fixedly disposed in the vicinity thereof,
A connection error can be made without displaying the above information.
Can be prevented.

From the above, the wiring structure according to the present invention
Is, for example, the pachinko machine of the arrangement game type
There are many ball passages (ball sockets) to detect the passage of game balls
The more the number of game ball detection switches,
Significant effects can be obtained.

Lastly, in the case of the present embodiment, the electric exposure portions of the game ball detecting switches 21 and the distribution connectors 34 to 3 are provided.
4, the set connector 35, 35, since the printed circuit board 33 or the like is protected by the mosquito <br/> bar 49, it is possible to prevent malfunction of the detection error of the game ball or game ball detection switch 21.
