Below the prize ball tank 4, a tank rail 5 for arranging and guiding the prize balls of the prize ball tank 4 is provided. The downstream end of the tank rail 5 is connected to a prize ball payout device 7 via a bending trough 6 for weakening the ball pressure. Reference numeral 8 is a prize ball discharge gutter for guiding the prize balls dispensed from the prize ball dispensing device 7 to a hit ball supply tray (not shown) on the front surface of the front frame 2, and 9 is a ball removal gutter 10
Is an overflow gutter that overflows the surplus prize balls of the hit ball supply tray to a lower ball receiving tray (not shown).

Reference numeral 11 is a winning ball discharge processing device incorporated in the lower part of the mechanism plate 3, and the ball cutting member 13 is swung by the operation of the solenoid 12 so that one winning ball is lined up in the winning ball passage 14.
Each one is made to flow into the winning ball discharge gutter 15. The prize ball discharge gutter 8, the ball removal gutter 9, the overflow gutter 10 and the like are covered by a removable back cover 16 as shown in FIG.

As shown in FIGS. 2 to 5, the bending trough 6 has two rows of substantially S-shaped sphere flow paths 17a through which the prize spheres flow.
Synthetic resin passage members 19a and 19b are superposed on the front and rear of the partition plate 18 so that 17b are partitioned and formed, and the plurality of engaging pieces 20 are engaged with each other to be integrally assembled. Further, a ball removing device 21 is provided between the front and rear passage members 19a and 19b. This ball removing device 21
Is a ball-removing valve 21a for opening and closing a ball-removing port opened in the ball passages 17a and 17b, an engaging lever 21b for constraining the ball-removing valve 21a to a position where the ball-removing port is closed, and an engaging lever by rotation. It is composed of an operation piece 21c for releasing the restraint of the ball extracting valve 21a via 21b and removing the prize ball of the prize ball tank 4 into the ball removing trough 9.

Therefore, as shown in FIG. 5, the front passage member 19a constituting the bending trough 6 is provided with fitting long holes 22 and 22 which are opened on the front side surface, and the insertion piece protruding outward from the side edge. 23 are integrally provided. Further, as shown in FIG. 4, positioning protrusions 24, 24 are integrally formed on the mechanism plate 3 so as to correspond to the fitting long holes 22, 22, respectively, and the insertion piece 23 is inserted and locked. The slot 25 is opened.

The fitting long holes 22 and 22 are two circular holes 22a and 22 which are separated by a narrow space 26 as a locking portion.
b, each of the circular holes 22a, 2
Small protrusions 27, 27 are provided at the front edge of 2a to be inserted and locked in the notch holes 24a, 24a formed in the bases of the positioning protrusions 24, 24.

In order to attach the bending trough 6 to the mechanism plate 3 in the above-described structure, one of the fitting elongated holes 22 and 22 of the positioning projections 24 and 24 is circular as shown by chain lines in FIGS. 6 and 7. While fitting the holes 22b, 22b and pressing the bending trough 6 against the mounting surface of the mechanism plate 3, slide it laterally,
The other circular holes 22a, 22a are fitted into the positioning protrusions 24, 24 as indicated by solid lines in the figure. As a result, the small protrusion 2
7 and 27 are notch holes 24a and 24 of the positioning protrusions 24 and 24.
The insertion pieces 23 are inserted into the slots 25a and are attached to the correct positions. At this time, the fitting long holes 22, 22
The narrow gaps 26, 26 reliably prevent the bending trough 6 from rattling in the lateral direction. Also, the positioning protrusions 24, 24
With the fitting of the fitting long holes 22 and 22, the accuracy of the mounting position of the bending trough 6 is maintained.

Further, in this embodiment, in order to more securely fix the bending trough 6 to the mechanism plate 3, the front passage member 19 of the bending trough 6 is provided.
The engaging hole 28 is formed in a, and the mechanism plate 3 is provided with an engaging piece 29 that engages with the engaging hole 28 at the mounting position of the bending trough 6 and a positioning piece 30 that engages with the side portion of the bending trough 6. It is provided. This engagement piece 2
9 and the positioning piece 30, the tip claw portion always projects from the surface of the mechanism plate 3, and is provided with elasticity so as to return to the original projecting position when this is released from the pressing of the bending trough 6. Note that these elasticity can be obtained by opening the slit 32 in the mechanism plate 3.

Therefore, when the bending trough 6 is attached, the bending trough 6 is slid laterally while pressing the engaging piece 29 and the positioning piece 30 against elasticity, and the bending trough 6 is mechanically moved. Attach to plate 3. Simultaneously with this mounting, the tip claw portion of the engaging piece 29 is pressed in conformity with the engaging hole 28.
9 is elastically returned, and its tip claw portion engages with the engagement hole 28. In addition, the positioning piece 30 is returned by the elastic force to bend the bending gutter 6
Engage the sides of. As a result, the bending trough 6 can be fixed and positioned more reliably, and rattling and positional deviation do not occur at all.

Further, in the present embodiment, as shown in FIG. 8, the tip of the bending gutter 6 approaches the engaging piece 29 with the bending gutter 6 attached to the mechanism plate 3 in the rear passage member 19b constituting the bending gutter 6. Opposing bar members 31 are provided so that they can be pressed in the front-back direction. When the bending trough 6 is attached to the mechanism plate 3, the rod member 31 is pushed forward with a finger so that the tip of the rod member 31 comes into contact with the engaging piece 29 as shown by the chain line in FIG. 29 for engagement hole 2
Since it can be detached from 8, the bending trough 6 attached to the mechanism plate 3 can be easily removed as necessary.
