Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a prize ball case in a pachinko machine that allows the prize ball case to be easily attached to a mechanism plate on the back side of a game board without screwing.

Conventionally, prize ball cases have been attached using multiple screws, which is very time-consuming, and the installation space is narrow because other back parts are attached, so screw fixing work is difficult. This is extremely difficult and has significantly reduced work efficiency. Furthermore, when replacing the prize ball case, the screws had to be removed each time, which was extremely troublesome.

In view of the above, the present invention provides mounting flange pieces on both the left and right sides of the prize ball case, inserts the side edge of one of the flange pieces into the groove of the frame piece provided on the mechanism plate, and holds the other flange piece. A rotatable locking lever is pressed into contact with the top surface of the piece, and the prize ball case can be easily attached without any troublesome work such as fixing with screws. Furthermore, the prize ball case can be easily attached and detached so that the prize ball case can be easily replaced.

The present invention will be explained below with reference to the illustrated embodiments.
Reference numeral 1 denotes a prize ball case, and 2 a mechanical plate for attaching back parts to which the prize ball case 1 is attached, which is attached to the back side of the game board. In this embodiment, the prize ball case 1 has a vertical cylindrical reservoir 3 in which a fixed number of balls can be stored, and an upper valve 4 and a lower valve 5 are rotated by pivots 6 and 7 above and below the reservoir 3. An opening/closing operation plate 9 is connected to the upper end of an operating rod 8 which is freely pivoted and is moved upwardly by a safety ball between the upper valve 4 and the lower valve 5.
is provided so as to be vertically movable, and the upper valve 4 and the lower valve 5 are alternately opened and closed by the vertical movement of the opening/closing operation plate 9, and the reservoir portion 3 of the prize ball case 1 Flange pieces 10 and 11 for attachment are integrally formed on both the left and right sides of.

The mechanism plate 2 has frame pieces 12a, 12b, 12c, and 12d that abut against the upper and lower end surfaces of the prize ball case 1 and the side edges of the flange pieces 10 and 11 to accurately position the prize ball case 1 at a predetermined installation position. Protruding,
Frame piece 12a corresponding to the one flange piece 10
has a groove 1 into which the side edge of the flange piece 10 can be inserted.
form 3. Incidentally, a ridge portion 14 that is higher than the corresponding frame piece 12b is integrally provided on the side edge of the other flange piece 11 and projects therefrom. Further, an L-shaped locking lever 15 is provided on the mechanism plate 2 above the flange piece 11, and one end of the locking lever 15 is rotatably supported by a shaft 16. The locking lever 15 has a spherical protrusion 17 protruding from the lower surface of the other end, and an operating knob 18 on the upper surface of the bent portion.

In the present invention having the above configuration, the prize ball case 1 is first attached to the frame piece 1 protruding from the mechanism plate 2.
The side edge of one flange piece 10 of the prize ball case 1 is inserted into the groove 13 of the prize ball case 1 to bring the lower surface of the prize ball case 1 into close contact with the mechanism plate 2. With this, the prize ball case 1 has each frame piece 12a, 12b, 12c, 12
d provides a precise positioning function to prevent movement. After that, operate the locking lever 15 and turn the knob 1.
When 8 is pinched and rotated downward, the spherical protrusion 17 on the lower surface climbs over the ridge 14 of the other flange piece 11 and comes into pressure contact with the upper surface of the other flange piece 11. In addition, when removing the prize ball case 1, contrary to the above, first rotate the locking lever 15 upward to release the pressure contact of the flange piece 11, and then attach the side edge of one flange piece 10 to the frame piece 12a. It can be easily removed by pulling it out from the groove 13. After the prize ball case 1 is installed, the spherical protrusion 17 will not go over the ridge 14 unless the locking lever 15 is rotated artificially.
There is no risk that the prize ball case 1 will fall out accidentally.
A firm installation can be maintained.

As described above, according to the present invention, the prize ball case 1
One of the flange pieces 10 and 11 formed on the left and right sides of the mechanism plate 2 is inserted and held in a groove 13 of a frame piece protruding from the mechanism plate 2, and the other flange piece 11 is pressed into contact with a rotatable locking lever 15. Therefore, the prize ball case 1 can be attached and fixed to the mechanism plate 2. Therefore, there is no need for the troublesome and difficult work of screwing in a narrow installation space as in the past, making it possible to install the prize ball case 1 extremely easily and quickly, improving work efficiency when assembling the pachinko machine. can be significantly increased. Also, prize ball case 1
It has the advantage that it can be easily repaired or replaced if it breaks down.
