DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 8 and 12, a replenishment tank 10 is disposed on the upper back of the pachinko gaming machine 2, and prize balls are replenished from the replenishment tank 10. The supply tank 10 is counted by the counter 6 from the supply basket 3 and game balls are supplied from the supply basket 3 through the supply pipe.
[0009]
As shown in FIG. 1, the replenishing tank 10 has a peripheral wall 13 formed on the outer periphery and an inclined bottom surface 12 inclined leftward, and a ball flow lower port 11 is formed at the lowest position. This ball flow lower port 11 is connected to a supply rail 8 shown in FIG.
Further, a sphere detection switch S is fitted on the inclined bottom surface 12 so that the sphere detection piece 14 (sphere detection portion) protrudes upward from the inclined bottom surface 12. When a load is applied on the ball sensing piece 22, the ball detection switch S is turned on, and it is detected that the remaining balls in the replenishing tank 10 are insufficient, and are counted by the counter 6 from the replenishing basket 3. A predetermined number of balls will be replenished.
[0010]
Next, the main part of the present invention will be described.
In the replenishment tank 10, the present invention is provided with ball receiving rods 20 a to 20 d for receiving game balls spilled from the replenishment tank 10.
[0011]
A first embodiment having such a configuration is shown in FIGS.
An auxiliary frame body 25 is fixed to the front portion of the replenishing tank 10 with screws 26, and the auxiliary frame body 25 constitutes a ball receiving rod 20a. The ball receiving rod 20 a has an inclined bottom surface 21 that is inclined from right to left, and its front wall 22 is slightly higher than the peripheral wall 13. This prevents the falling ball from jumping over the front wall 22 and falling.
[0012]
In addition, a return port 24 through which a game ball can pass is formed in the peripheral wall 13 of the replenishing tank 10 at almost the lowest position of the inclined bottom surface 21. As a result, as shown in FIGS. 2 and 3, the game ball that has fallen from the supply tank 10 and has flowed into the ball receiving bowl 20 a is guided to the inclined bottom surface 21 and stored in the lowest position. The falling ball once stored in the ball receiving bowl 20a is returned to the replenishment tank 10 due to its drop as the game balls in the replenishment tank 10 disappear. In such a configuration, the spilling ball naturally returns and is used again as a prize sphere, and there is no need for post-processing of the spilling sphere, and there is an advantage that no error is caused in the counting management of the supplementary sphere. is there.
[0013]
Next, a second embodiment will be described with reference to FIGS.
4 and 5, the inner casing 31 constituting the replenishing tank 10 is fixed in the outer casing 30, and the left and right and front portions are disposed between the peripheral wall 32 of the outer casing 30 and the peripheral wall 34 of the replenishing tank 10. A narrow U-shaped sphere receiving rod 20b is formed. The peripheral wall 32 of the outer casing 30 is slightly taller than the peripheral wall 34 of the inner casing 31, thereby preventing the falling ball from jumping over the front wall 32 and falling. The bottom surface of the replenishing tank 10 including the inner casing 31 is opened including the outer casing 30 to serve as a ball flow lower port 11 (see FIG. 1 and the like) connected to the supply rail 8.
[0014]
An inclined bottom surface 25 is formed on the bottom surface of the ball receiving bowl 20b to allow the received game ball to flow to the left, and the falling balls are stored in order from the lowest position of the inclined bottom surface 25 due to the drop. The stored spilled ball is directly taken out from above.
[0015]
On the other hand, in order to facilitate the removal, as shown in FIG. 6, the inclined bottom surface 25 forms a discharge port 34 at the lowest position of the bottom surface for guiding the game ball, and the discharge port 34 is manually opened and closed by an opening / closing mechanism. It may be operable. That is, in the opening / closing mechanism of FIG. 6, the discharge port 34 is blocked by a slide opening / closing piece 35 having a handle 36 at one end and an opening 38, as shown in FIG. Yes. The slide opening / closing piece 35 is slidable in the left-right direction by a guide rail 39 formed on the lower bottom surface of the replenishing tank 10, and a positioning edge 37 formed on the other end of the handle 36 contacts the guide rail 39. When it is pulled out until it comes into contact, as shown in FIG. 6B, the opening 38 formed in the slide opening / closing piece 35 coincides with the discharge port 34, and the game ball staying in the ball receiving rod 20b is discharged. In such a configuration, the operator can easily collect the falling ball.
[0016]
7 and 8 show a third embodiment, in which the auxiliary communication path 40 is connected to the discharge port 34 formed in the ball receiving rod 20c, and the other end of the auxiliary communication path 40 is connected to the supply tank 10. This relates to the configuration connected to the ball removal passage 9. Here, the configuration of the replenishing tank 10 is the same as the basic configuration of FIGS.
[0017]
Here, the auxiliary communication passage 40 includes a wide mouth portion 41 communicating with the discharge port 34, and locking edges 42, 42 projecting on both sides of the mouth portion 41 are provided below the discharge port 34. The mouth portion 41 is detachably connected to the guide rails 43 and 43 disposed on both sides of the bottom. As a result, the assembly of the auxiliary communication path 40 is facilitated, and when the auxiliary communication path 40 is not provided, the above-described slide opening / closing piece 35 can be attached to the guide rails 43, 43, and the pulling operation can be performed. It is also possible to collect the spilled ball directly from the discharge port 34.
[0018]
The ball removal passage 9 is well known and communicates with the ball flow lower port 11 of the replenishment tank 10 and opens the switching operation portion 9a, thereby allowing the replenishment tank 10 to pass through the ball removal passage 9 during maintenance management of the gaming machine. The game balls inside are collected. Then, by connecting the auxiliary communication passage 40 to the ball removal passage 9, the spilling ball is also recovered to the outside by the opening operation of the switching operation portion 8.
[0019]
9 to 11 show a fourth embodiment, in which a ball receiving rod 20d is constituted by an auxiliary frame 25 attached to the front portion of the replenishing tank 10 by screws 26, and the inclined bottom surface 21 of the ball receiving rod 20d is formed. The left end which is almost the lowest position is opened, and this is used as the discharge port 50.
[0020]
Here, the game ball spilled from the replenishment tank 10 is received by the bottom surface of the ball receiving bowl 20d, flows down to the left side by the drop by the inclined bottom surface 21, and is discharged from the discharge port 50 to the left side of the game machine. In other words, the released game ball will naturally fall avoiding the various substrates and wirings arranged immediately below the replenishment tank 10, and the damage will be prevented.
[0021]
Further, in order to reliably prevent the game ball from colliding with various boards and wirings, as shown in FIG. 12, an auxiliary passage 60 is provided in the outer frame 7 in the vertical direction, and a funnel portion formed at the upper end of the auxiliary communication passage 60 In 61, the spilling ball of the discharge port 50 may be received and flowed downward. The falling ball flowing down from the outlet end of the auxiliary communication passage 60 is received by a recovery container or the like and recovered outside the machine.
[0022]
【The invention's effect】
As described above, the present invention provides a ball receiving portion such as a ball receiving cage on the outer periphery of the replenishment tank, so that when the game ball is supplied from the replenishment pipe of the island facility into the replenishment tank, Even if the game ball spills out of the supply tank due to momentum, the spilled ball is captured by the ball receiving rod and does not fall down and damage various devices.
[0023]
In addition, since the return port through which the game ball can pass is provided on the side wall of the replenishing tank at the lowest position on the inclined bottom surface of the ball receiving bowl, the spilled ball once stored in the ball receiving bowl is naturally transferred to the replenishing tank. It will return and will be used again as a prize ball, and there is an advantage that no post-processing of the spilling ball is necessary and no error is caused in the management of the supply ball. In addition, a separate structure and a discharge path are not required, and the structure is simple.
[0024]
Further, a ball receiving rod connected to the supply tank via the auxiliary communication passage is connected to the ball receiving rod connected to an auxiliary communication passage to the ball receiving rod and the other end of the auxiliary communication passage connected to a ball removal passage connected to the supply tank. In the configuration communicating with the extraction passage, the spilling ball is collected through the existing sphere extraction passage, the spilling ball can be reliably collected, and the existing sphere extraction passage is used. Because there is, the structure becomes simple.
[0025]
On the other hand, even when the auxiliary ball discharge path provided separately is connected to the ball receiving rod, the falling ball can be reliably collected.
