A game board 5 is provided on the rear side of the glass door frame 3, and an upper ball tray 6 is attached to the front surface of the front plate 4. In addition, a lower sphere tray 7 for storing excess spheres of the upper sphere tray 6 is mounted on the lower front surface of the front frame 2. Reference numeral 8 denotes a sphere outlet of the surplus sphere, and a cylindrical guide rod 9 is provided at the sphere outlet 8.
[0011]
As shown in FIGS. 2 and 3, the lower ball tray 7 includes an upper cover body 10 a and a lower cover body 10 b, and has a dish portion 11 that stores a large amount of pachinko balls. The bottom wall of the dish portion 11 A ball outlet 12 through which a plurality of pachinko balls fall is opened at 11 a, and the bottom wall 11 a is inclined toward the ball outlet 12. 13 is an ashtray mounted between the upper cover body 10a and the lower cover body 10b.
[0012]
On the lower surface of the bottom wall 11a, a plate-like opening / closing member 14 that opens or closes the ball outlet 12 is pivotally supported at its rear end 14a via a winding spring 15 as an urging member. The ball outlet 12 is closed by locking the locking piece 16 projecting from the front end with the locking member 17. Reference numeral 18 denotes a ball distribution protrusion provided at the front end of the opening / closing member 14.
[0013]
The locking member 17 is formed in an inverted L shape as shown in FIG. 4 and is pivotally supported by a shaft 19 protruding from the upper cover body 10a. Then, a locking portion 20 that locks the locking piece portion 16 is provided at the lower end, and an inclined surface 21 on which the locking piece portion 16 slides is formed on the lower surface thereof with an inclination of about 45 °. The operation unit 22 is on the side. The operation unit 22 is loaded with a weight 23 so as to always rotate downward. Reference numeral 24 denotes a downward movement restricting portion of the opening / closing member 14, and 25 denotes a rotation restricting protrusion of the locking member 17. The locking member 17 is selected to be a pivotal support position that does not rotate unnecessarily even when a load such as the weight of a pachinko ball is applied to the opening / closing member 14.
[0014]
In the lower ball tray 7 configured as described above, the opening / closing member 14 is always moved upward by the bias of the winding spring 15 and the locking member 17 is rotated downward by the weight 23 as shown in FIG. The locking portion 20 is engaged with the locking piece portion 16 to close the ball outlet 12, and the locking portion 16 and the locking portion 20 are engaged by operating the operation portion 22 by hand. Is released, and the opening and closing member 14 can be moved downward. When the opening / closing member 14 moves downward against the urging force of the winding spring 15 due to the weight of the pachinko ball, the ball outlet 12 is opened as shown in FIG.
[0015]
Next, the action of removing the balls from the ball tray will be described with reference to the drawings. As shown in FIGS. 4 and 6, the normal dish portion 11 has an opening / closing member 14 locked and held by a locking member 17 to close the ball outlet 12. In this state, when the finger is placed on the operation unit 22 and rotated upward (in the direction of the arrow of the operation unit 22), the engagement between the locking unit 20 and the locking piece 16 is released as shown by a chain line in FIG. The Then, the opening / closing member 14 moves down to the position of the downward movement restricting portion 24 shown by a chain line in FIG. 6 against the urging force of the winding spring 15 by the ball weight of the pachinko ball located at the ball outlet 12 to open the ball outlet 12. Then, the pachinko balls stored in the dish portion 11 are dropped and extracted into a ball box B placed below the lower ball tray 7. Further, the pachinko ball in the center part falls into the ball box B while being distributed left and right by the ball distribution protrusion 18. At this time, the locking member 17 is moved back to the position indicated by the solid line in FIG.
[0016]
When the pachinko ball of the plate portion 11 is extracted, the opening / closing member 14 is released from the ball weight of the pachinko ball, and is moved upward by the bias of the winding spring 15, so that the locking piece 16 is an inclined surface of the locking member 17. By pressing 21, the locking member 17 rotates as shown by a chain line in FIG. 4. Further, when the locking piece 16 slides on the inclined surface 21 and comes out of contact with the inclined surface 21, the opening / closing member 14 moves back to the position where the ball outlet 12 shown in FIG. 17 is again moved back to the position indicated by the solid line in FIG. 4 by the weight 23, and the locking portion 20 engages with the locking piece portion 16 to lock and hold the opening / closing member 14 at the position where the ball outlet 12 is closed.
[0017]
In this way, once the locking member 17 is operated to disengage the locking portion 20 and the locking piece portion 16, the pachinko ball is placed on the dish portion 11 even when the locking member 17 is released. As long as there is, the opening and closing member 14 is moved downward to open the ball outlet 12. When the pachinko ball disappears in the dish portion 11 and the ball removal is completed, the ball outlet 12 is automatically closed and the opening and closing member 14 is locked. Since it holds, it is convenient for the player. Further, even if the locking member 17 is mistakenly operated in a state where there is no pachinko ball in the dish portion 11, the opening / closing member 14 does not move down due to the urging force of the urging member 15, and the locking member 17 is not affected by the weight 23. Therefore, the opening / closing member 14 is locked and held, so that the ball outlet 12 is not left open. In the above embodiment, when the locking piece 16 of the opening / closing member 14 moves backward, the locking member 17 is moved by contacting the inclined surface 21 formed on the lower surface of the locking member 17. However, as shown in FIG. 7, an inclined convex portion 21a may be formed on the upper surface of the locking piece portion 16, and the locking member 17 may be moved by the inclined convex portion 21a as shown in FIG. .
