The variable mounting base 5 has a base rail member 6 fixed to the upper surface of the mounting base 1 with screws 7, and is extended and contracted by an outer cylinder 8 and an inner cylinder 9 on the base rail member so as to be movable and adjustable in the width direction of the base. A free column 10 is provided, and the collection ball tank 4 is supported on the column. Therefore, the collection ball tank 4 is supported by the variable mount 5 so that the setting position can be finely adjusted in the pachinko machine width direction and the height direction. The pachinko machine 2 is hinged so that the front frame 12 can be opened and closed at one side edge of the machine frame 11, and a known locking device (not shown) is provided at the other side edge for holding the closed state. It is a thing. Reference numerals 13 and 14 denote an upper plate and a lower plate provided on the front surface of the front frame 12.

  The collection ball tank 4 is composed of a bottom wall 15 and both side walls 16, the bottom wall 15 is formed in a slanted shape toward the rear, and a ball assembly portion 17 is formed on a rear side edge thereof. A counting device 18 is provided below, and a hose 19 made of a coil spring is provided at the discharge port of the counting device, and the hose is suspended from the ball collecting rod 3.

In addition, a ball tray 22 including a bottom wall 20a, both side walls 20b, and a front wall 20c is provided on the front side of the collection ball tank 4 so as to slide on the bottom wall 15 and slide in the front-rear direction. Similar to the bottom wall 15, the bottom wall 20a is formed to have a gentle slope toward the rear. A longitudinal notch 21a is formed at the upper edge of both side walls 20b, and the catch claw 21b projecting from the inside of the upper edge of the both side walls 16 is engaged with the longitudinal notch so that the ball tray 22 does not fall off. It can be slid back and forth. Further, as shown in FIG. 5 , a pair of guide rollers 23 are rotatably provided on the lower surface of the collection ball tank 4 so that the sliding is smooth, and the lower surface of the ball tray 22 is in contact with the rollers. A plate- shaped guide rail 24 is formed in a hanging shape.

  Further, 25 is a detection switch fixed to the lower surface of the collection ball tank 4, and 26 is fixed to a part of the guide rail 24 by a screw 27 so that the detection switch can be operated when the ball receiving tray 22 slides. It is a switch operating plate. Further, a coil spring 29 in a compressed state is accommodated in a cylindrical portion 28 integrally formed on the lower surface of the bottom wall 15 of the collection ball tank 4, and a rib 30 suspended from the bottom wall 20a of the ball tray 22 is provided at one end of the spring. By engaging, the ball tray 22 is urged forward by the elasticity of the spring.

  Therefore, as indicated by an arrow in FIG. 3, the ball receiving tray 22 extends to the lower part of the ball discharge port 31 on the back of the pachinko machine due to the elasticity of the spring 29, and the front wall 20 c of the ball receiving tray 22 is the pachinko machine 2. By collecting the pressure on the back surface of the front frame 12, a collection ball P such as an out ball discharged from the ball discharge port can be received by the ball tray 22. Then, the collected sphere received by the sphere receiving tray falls from the sphere collecting portion 17 of the collected sphere tank 4 and flows down from the hose 19 to the sphere collecting bowl 3 through the counting device 18. Even if the pachinko machine 2 is replaced and the position of the ball discharge port 31 changes in the front-rear direction, the ball receiving tray 22 moves forward by the elasticity of the spring 29 because the spring 29 is elastic.
