As shown in FIG. The mechanism plate 1 can be supported on the back side of the front plate 10 so as to be openable and closable by being inserted into a bearing 15 provided on the back surface and detachably fixing a fastener 16 such as a clamp to the fixing piece 14. Reference numeral 17 denotes a concave portion provided for fixing the same fastener 18. The mechanism plate provided on the back surface of the front plate 10 may be composed of one member as shown in FIG. 1, or may be composed of two or more members separated at appropriate portions. .

The ball tank 2 is fixed to a concave portion 20 formed on an upper portion of the mechanism plate 1 by a screw 21. Reference numeral 23 denotes an inclined ball receiving piece protruding from the mechanism plate 1 so as to be located below the outlet of the ball tank 2. The upper surface of the ball receiving piece 23 is enlarged in FIG. As shown, a slight step 24 is formed along the flow direction of the pachinko balls at intervals of approximately one pachinko ball.

Also, as shown in FIGS.
Reference numerals 28 denote ball receiving pieces having an inclined surface protrudingly provided on the mechanism plate 1 at appropriate intervals below the inclination of the ball receiving pieces 23. The alignment gutter frame 3 is made of plastic, the inside of which is partitioned into three rows by a partition wall 30, and cutouts 32 to 35 in which the respective ball receiving pieces 25 to 28 are exposed are formed on a bottom surface 31, A screw hole 3 formed in the mechanism plate 1
6. Screws 38 are screwed onto the bosses 37 and attached to the mechanism plate 1 to form a ball alignment gutter. And the bottom 31
And a step 39 is formed at the boundary between the ball receiving pieces 25 to 28. Also, the upper and lower surfaces 31 of the ball receiving pieces 25 to 28
A slight step 40 at intervals of almost one pachinko ball
Are formed. Reference numeral 41 denotes a ball level suspended swingably on a boss 42 projecting from the mechanism plate 1.

The curve rail 4 is attached to bosses 43 and 44 projecting from the mechanism plate 1 by screws 45,
The pachinko ball that has flowed down the ball alignment gutter is guided into the curve rail 4. Reference numerals 46 to 48 denote arc-shaped ball receiving pieces projecting from the mechanism plate 1 so as to form a part of the outer peripheral wall of the curve rail 4 when attached.

The payout mechanism 7 includes a prize ball payout device 5a.
And a payout ball payout device 5 b and a payout passage cover 6, and are attached to bosses 50 and screw holes 51 formed in the mechanism plate 1 by screws 52. Reference numeral 53 denotes a ball payout port provided in the mechanism plate 1. Numeral 54 denotes a gutter-shaped ball receiver formed on the mechanism plate 1 so as to form a part of a prize ball overflow path.
Reference numeral 5 denotes a ball receiving piece formed on the mechanism plate 1 so as to form a ball collision wall of the passage, and 56 denotes a mechanism plate 1 so as to form a part of the discharge passage.
This is a gutter-shaped ball receiving piece formed on the base. The pachinko balls that have passed through the curve rail 4 reach the payout mechanism 7 and pays out the prize balls and the lending balls to the ball payout port 53 by operating the prize ball payout device 5a and the ball rental device 5b.

The electronic control circuit board 8 is fixed to a screw hole 57 formed in the lower part of the mechanism plate 1 with a screw 58.
The power distribution board 9 is fixed to a screw hole 59 formed in an upper portion of the mechanism plate 1 with a screw 60.

In this ball alignment gutter, since the ball receiving piece 23 and the ball receiving pieces 25 to 28 projecting from the mechanism plate 1 constitute a part of the bottom surface, the weight of the pachinko ball flowing down the ball alignment gutter is used. However, since a part of the ball load is directly applied to the mechanism plate 1 and the ball load is directly applied to the mechanism plate 1, the load on the alignment gutter frame 3 is reduced. The durability is improved.

Further, since the step 24, the step 39, and the step 40 are formed along the flowing direction, each time the pachinko ball falls down the step while flowing down, the pachinko ball vibrates and the aggregate is released. For this reason, the aligning action is promoted, and the pachinko balls can be aligned in three rows to be smoothly guided to the curve rail 4, thereby preventing ball clogging.

By forming the mechanism plate 1 by die-casting a metal such as an aluminum alloy or a magnesium alloy, the rigidity can be increased, the deformation can be reduced, the wear resistance is superior to that of plastic, and it is originally conductive. Therefore, there is no possibility of static electricity being charged.
