The number of pachinko balls (prize balls) released by controlling the rotation speed of the motor 9a can be adjusted in units of one. On the other hand, the winning ball processing-related parts are divided into two systems so as to correspond to the winning ball receiver 29 set to be easy to win and the other winning ball receivers 30 in FIG. For example, seven pachinko balls are received upon receiving a winning signal corresponding to the winning ball receiver 29, and thirteen pachinko balls are received upon receiving other winning signals.
Releases.

The mechanism plate 10 is hinged to one side of the middle frame 6 so as to be freely rotatable.
The hooks 32, 32,... Of the mechanism plate 10 are hooked to 1, 31,... And are fixed on the back surfaces of the game board 7 and the lower game board 20 so as to overlap.

As shown in FIG. 6, a through hole 34 for inserting a cable 33 is formed in the lower game board 20. The through hole 34 is formed by expanding a side near the center of the pachinko machine 1 in a tapered shape from the back side to the front side of the pachinko machine 1.

On the other hand, a recess 35 is formed in the crosspiece 20c so as to be continuous with the through hole 34. As is apparent from FIG. 6, the width of the through hole 34 in the case where the concave notch 35 is not provided has a length a, whereas the width of the through hole 34 has the length b due to the provision of the concave notch 35. You can see that it has spread. In addition, since the one side of the through hole 34 is formed in a tapered shape as described above, the cable 33 can be easily pulled out of the pachinko machine 1 with a gentle curve.

Next, as shown by a chain line in FIGS. 1 and 2, a prepaid-card-compatible table-to-ball rental machine 15 arranged side by side with the pachinko machine 1 will be described. The inter-ball rental machine 15 has a card reader 36 having a function of reading the amount data of a prepaid card and writing the withdrawn amount data, built in a case body 37.

As described above, the input button 16 of the inter-ball lending machine 15 and the balance display portion 17 of the prepaid card are displayed on the upper ball tray 12.
, A cable 33 for electrically connecting them is drawn through the through hole 34 and the concave notch 35 of the lower game board 20 and further connected to the connector 19 facing the back surface of the front plate 14. Tip connector 33
Insert a.

In addition, the ball-to-ball rental machine 15 exemplified here is
There is no function of releasing the pachinko ball directly to the player as in the conventional type, and the motor 9a of the premium ball discharging device 9 is operated in response to a ball lending command of the input button 16, and the pachinko ball to lend to the upper ball tray 12 is provided. Are directly released.

The embodiment of the present invention has been described above.
Of course, the present invention is not limited to the above embodiment. For example, as shown in FIG. 7, the concave notch 35 may have the same tapered shape as the through hole 34. Further, as shown in FIG. 8, the concave notch 35 may be formed on the front side of the crosspiece member 20c (on the side that comes into contact with the front frame 4). In this case, the lower game board 2
Since it is not necessary to provide the through-hole 34 in the hole 0, it is possible to sufficiently cope with the case where the mechanism plate 10 is enlarged and extends over the cross member 20c as shown by the dashed line in FIG. Since the cable 33 is normally taken in and out by opening the front frame 4 as shown in FIG. 3, the recessed portion 3 is closed with the front frame 4 closed as shown in FIG.
Even if the gap between the opening 5 and the outer frame 2 is small, there is no problem in taking the cable 33 in and out.

The present applicant has already filed a patent application for a technique for facilitating insertion and extraction of the cable 33 by combining the through hole 34 of the lower game board 20 and the concave notch 10a provided on the mechanism board 10. However, the technology may be combined with the present invention as shown in FIG. Although the case where the recessed portion 35 is formed on the crosspiece member 20c beside the lower game board 20 has been described above, the same recessed portion 35 can be formed even when the lower game board 20 has the crosspiece member 20c on the lower side. Can be formed. Also, as shown in FIG. 10, the concave notch 35 may be provided at the lower corner of the lower game board 20 so as to straddle both the lateral and lower cross members 20c.

Further, although the cable 33 that is drawn through the inter-ball ball rental machine 15 is exemplified as the cable 33 that passes through the through hole 34, the use of the cable 33 is not particularly limited. For example, a decorative lamp may be provided on the upper ball tray 12 and a cable used to connect the lamp to a control device attached to the pachinko machine 1 may be used.
A cable for connecting the card reader to a control device attached to the pachinko machine 1 and incorporated in the pachinko machine 1 may be used. In addition to the case where the lower game board 20 is fixed to the front frame 4 as an integral part of the middle frame 6, only the lower game board 20 may be independently fixed to the lower side of the window hole 5.

[0025]

As described above, in the pachinko machine according to the present invention, a part of the cross member of the lower game board is cut out to form a concave notch,
Since the cable is guided by using the concave notch, even if most of the rear surface of the lower game board is closed by the mechanism plate, there is an effect that the cable can be smoothly inserted and removed.
