[Industrial applications]

 The present invention relates to a prize ball tank which is disposed on the back side of a pachinko machine and stores a prize ball that is paid out each time a winning ball is generated.

[0002]

[Prior Art]

 Conventionally, in a prize ball tank for pachinko machines, when the amount of prize balls stored in the tank decreases, a specified number of prize balls are transferred from the prize ball supply device provided in the island stand where the pachinko machines are lined up into the prize ball tank. Although a free gift ball is sent, various methods have been devised as a method for detecting when the storage amount is low.

For example, as disclosed in Japanese Utility Model Laid-Open No. 47-31887 (hereinafter referred to as “first conventional technique”), a shaft is tiltably supported on a bottom surface of an upstream side of a gutter disposed below a prize ball tank. When the amount of prize balls stored in the prize ball tank is almost empty, the tip of the ball detection lever is When the limit switch is turned on by tilting upward and the prize ball is staying on the ball detection lever, the limit switch is turned off by pressing the ball detection lever by the weight of the prize ball. There is something.

Further, recently, as disclosed in Japanese Utility Model Laid-Open No. 58-86171 (hereinafter referred to as second prior art), a vertical wall is provided so as to face the outlet of the tank, and the vertical wall swings. There is one in which the existing detection plate is provided so as to project slightly inside the tank, and a detector main body that is activated by the swing of the detection plate is provided outside the tank.

Furthermore, as disclosed in Japanese Utility Model Laid-Open No. 1-107390 (hereinafter referred to as third prior art), an outlet is formed at one end on the bottom surface of the prize ball tank, and the rear surface of the outlet is formed. The rear surface wall is bulged inward between the opening edge and the rear surface wall to form a ball collapsing portion, and an opening is provided along the rear surface wall at a position closer to the upstream side of the ball collapsing portion. There is a structure in which a part of the bottom wall of the prize ball tank is configured, a tilting piece whose one end is tiltably supported is provided, and a switch which operates according to the tilting operation is provided.

[0006]

[Problems to be solved by the device]

 By the way, recent pachinko machines increase the playability, so the number of prize balls paid out to the player is divided into several types, and when the special game state called a big hit is reached, the total amount paid out is far greater than in the past. Pachinko machines, which are equipped with a prize ball discharge device that quickly dispenses prize balls, have become the mainstream in order to increase the amount of payout and to shorten the payout time and to improve the satisfaction given to the player. ..

However, in the first conventional technique, the detection lever for detecting the amount of prize balls stored in the prize ball tank is provided on the bottom surface on the upstream side of the gutter below the prize ball tank, that is, just below the outlet of the prize ball tank. The prize balls flowing into the gutter from the outlet of the prize ball tank are aligned with the gently-sloped gutter while overlapping on the prize balls flowing from the other direction, forming a dumpling state on the detection lever. Since it is always biased to tilt upward, there is a risk that a so-called ball biting phenomenon will occur on the detection lever due to its operation, and the smooth flow of prize balls may be hindered.

Further, in the case of a big hit, the number of safe balls becomes large, but since the prize balls paid out according to the number of safe balls are paid out at high speed, the decrease of the prize balls in the prize ball tank is detected. In many cases, there is almost no prize ball left in the prize ball tank, so the supply of prize balls becomes sparse, and errors are likely to occur in the detection of the number of prize balls. There was a problem in that an error occurred even in the total number of prize balls, which made the player uncomfortable.

In the second conventional technique, since the vertical wall is provided at the outlet of the tank and the detection plate is provided at the vertical wall, the ball pressure from the upstream side of the sphere at the outlet is the same as that from the side by the detection plate. Due to the ball pressure, a composite force acts on the prize ball near the upper side of the outlet, which causes irregular flow of the balls, and sometimes the forces balance each other and the ball pressure in the downward direction is reduced, resulting in a ball catching phenomenon. There was a problem that it was easy to cause it.

Further, in the third conventional technique, since the opening is provided along the rear wall at the upstream side of the ball collapsing portion in the prize ball tank, and the tilting piece is provided in the opening, the prize ball is While flowing down to the outlet, the prize ball on the tilting piece is blocked by the collapsing part, and the bottom surface in the vicinity of it does not tilt downward, so the prize ball remains on the upper surface of the tilting piece. Therefore, even if the prize ball tank became empty, the tilting piece did not work, and there was a problem that prize balls could not be supplied.

Further, since the tilting piece is located above the outlet, the tilting piece tilts when the prize ball on the upper surface of the tilting piece disappears even if the prize ball remains in the prize ball tank to some extent. Therefore, there is a problem that prize balls are supplied in excess of the permissible amount, and the prize balls overflow from the prize ball tank.

Therefore, the present invention has been made in view of the above-mentioned problems, and always stabilizes the flow state of the prize ball in the prize ball tank to the outlet so that the prize ball is not clogged. It provides a premium ball tank for pachinko machines that can be supplied to the ball outflow gutter without interruption.

[0013]

[Means for solving problems]

 In order to solve such a problem, the prize ball tank for a pachinko machine of the present invention is formed in a box shape with an open upper surface, and an outlet is formed at one end of the bottom surface to allow the prize ball to flow down to the prize ball outlet gutter. A prize ball for a pachinko machine in which the bottom surface is provided so as to be inclined downward toward the outlet, and the rear wall is bulged inward between the rear edge of the outlet and the rear wall to form a ball collapsing portion. In the tank, an opening is provided on the bottom surface between the outlet and the front wall, and the opening constitutes a part of the bottom surface so that the shaft supporting portion is located on the side opposite to the side wall of the one end and the tip is The tilting plate located on the side wall side of one end is pivotally supported so as to be tiltable, and the ball detection switch that operates for the tilting movement is arranged on the back side of the tilting plate.

[0014]

[Action]

 The bottom of the prize ball in the tank is inclined downward toward the outlet, and by forming a part of the bottom surface between the outlet and the front wall and pivotally supporting the tilting plate, the prize ball is directed toward the outlet. The free-falling external ball pressure is not generated and the flow is done very naturally, and the prize ball is smoothly sent to the prize ball guide trough without interruption. In addition, even if the prize balls in the prize ball tank decrease to the outlet, the prize balls do not remain anywhere on the bottom surface, and the tilting plate performs regular detection operation without being affected by the storage balls. ..

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial rear view of a pachinko machine equipped with the prize ball tank of the present invention, where 1 is a mechanism plate mounted on the back surface of the game board so that it can be opened and closed, and 2 is an upper part of the mechanism plate 1. The attached prize ball tank 3 is provided below the prize ball tank 2 and is a prize ball outlet gutter for aligning the prize balls and guiding them to a prize ball payout device (not shown). In the pachinko machine configured as described above, the prize balls stored in the prize ball tank 2 continuously flow down the prize ball outlet gutter 3 and are guided to the prize ball payout device. Then, when the safe balls are generated, the prize ball payout device is operated, and a predetermined number of prize balls are guided to a hit ball supply tray (not shown) on the front surface of the pachinko machine.

Accordingly, the prize ball tank 2 according to the present invention is formed in a box shape of a plane substantially rectangular shape whose upper surface is open as shown in FIGS. It is formed of a rear wall 4 which is in contact with the front wall 5, a front wall 5 facing the rear wall 4, a left side wall 6, a right side wall 7 and a bottom surface 8. A substantially rectangular outflow port 9 corresponding to the upstream end portion of the prize sphere derivation trough 3 is provided at one end of the bottom surface 8 and substantially in the center of the front-rear width. Further, the rear wall 4 is swollen inward between the rear opening edge 9a of the outlet 9 and the rear wall 4 to form a ball collapsing portion 10. The ball collapsing portion 10 is for preventing the prize ball from clogging at the outlet 9 portion. Further, the bottom surface 8 is composed of three inclined surfaces having different inclination angles, and the inclined surface 8a on the rear wall 4 side and the inclined surface 8c on the front wall 5 side incline downward toward each other, and The inclined surface 8b is inclined downward to the outlet 9 side.

Therefore, according to the present invention, a rectangular opening 11 is provided between the outlet 9 and the front wall 5 so as to be close to the outlet 9 and extends along the longitudinal direction of the prize ball tank 2. A tilting plate 12 forming a part of the bottom surface 8 is pivotally supported in the opening 11. The tilting plate 12 is provided with a shaft support portion 13 at the base end on the right side wall 7 side, the tip end being positioned on the left side wall 6 side, and the upper surface is inclined. Further, a pressing piece 14 is hung on the back surface of the tilting plate 12 toward the tip end, and is positioned in contact with the actuator piece 17 of the ball detection switch 16 arranged on the back surface of the tilting plate 12. When the tip end side of the tilting plate 12 is lowered, the upper surface of the tilting plate 12 and the tilted surface 8c of the bottom surface 8 are flush with each other, and the actuator piece 17 is pressed by the pressing piece 14 so that the ball detection switch 16 moves. It is kept off. On the contrary, when the tip end side of the tilting plate 12 rises, the tip end side of the tilting plate 12 projects slightly above the opening 11, and when the actuator piece 17 is released by the rise of the pressing piece 14, it becomes ON and the detection signal is output. The signal is sent out, and a replenishing device (not shown) is activated by this detection signal to replenish the free gift ball tank 2 with a given free gift ball.

Therefore, the prize spheres stored in the prize sphere tank 2 sequentially flow down along the bottom surface 8 which inclines downward with each occurrence of the winning ball and head toward the outlet 9, but the inclined surfaces 8a, 8b, 8c The tilting plate 12 is inclined so as to be suitable for the prize ball to flow down, and the tip end of the tilting plate 12 is located on the left side wall 6 side and the base end shaft support 13 is located on the right side wall 7 side. There is no obstacle, and the tilting plate 12 is flush with the bottom surface when the tilting plate 12 is tilted downward, so that no unnecessary external pressure is applied to the entire falling ball to the outlet 9 of the prize ball. The flow of water becomes extremely natural. As a result, the prize balls flowing down from the outlet 9 are prevented from being pressed against the prize balls accumulated on the surface of the prize ball derivation trough 3, and the gift balls are smoothly sent to the prize ball derivation trough 3 without interruption.

In FIG. 5, the front opening edge 11a of the opening 11 and the front end edge 12a of the tilting plate 12 are directed from the tip end side of the front end edge 12a of the tilting plate 12 toward the shaft supporting portion 13 side. It is formed by inclining so as to have a predetermined angle with respect to the longitudinal direction of the prize ball tank 2. According to this, the amount of the prize ball stored in the prize ball tank 2 decreases during operation, or the prize ball tank When the ball-removing operation in 2 is performed, the tip moves upward if the prize sphere does not remain on the upper surface of the tilting plate 12, and a part of the tip projects upward from the bottom surface 8 and the front edge 12a of the tilting plate 12 moves. There is a risk that the prize ball at the front side of the jetty may be left behind or may enter the lower surface of the tilting plate and obstruct the operation of the tilting plate 12, but as described above, the front end of the tilting plate 12 Since the edge 12a is inclined to the lower end side, the remaining prize ball is As shown in FIG. 6, since all flow down along the front edge of the tilting plate 12 and are guided to the outflow port 9, the prize ball does not remain on the bottom surface 8.

The one shown in FIG. 7 also eliminates the remaining of the prize balls, and the upper surface is gradually lowered on the bottom surface 8 between the tilting plate 12 and the front wall 5 toward the shaft support 13 side of the tilting plate 12. The two projecting pieces 18, 18 'are provided so as to project substantially parallel to the front wall 5 over the distance between the left side wall 6 and the shaft supporting portion 13 of the tilting plate 12. Further, the protruding piece 18 near the tilting plate 12 is provided slightly lower than the protruding piece 18 'near the front wall 5, and is formed higher than the height dimension when the tilting plate 12 is raised. As a result, all the prize balls that enter between the front wall 5 and the tilting plate 12 are supported by the projecting pieces 18, 18 'and roll on the projecting pieces 18, 18' as shown in FIG. Side or the shaft support portion 13 side and naturally flows down to the outlet 9, so that the prize ball does not remain in the prize ball tank 2. Since the ball collapsing portion 10 is provided at the rear opening edge 9a of the outlet 9 in the prize ball tank 12, the ball collapsing portion 10 may prevent the prize ball from flowing down. Since the bottom surface 8 on the upstream side of the ball collapsing part 10 is formed on the inclined surface 8a that inclines inward, all the prize balls flow down along the inclined surface 8a, and the prize ball remains. There is no.

[0021]

[Effect of the device]

 As described above, the prize ball tank of the present invention has an opening at the bottom surface between the outlet and the front wall, and the opening constitutes a part of the bottom surface to position the shaft support portion on the upstream side and the tip end. Since the tilting plate located on the downstream side is pivotally supported so that it can be tilted, the prize ball in the tank always flows down naturally without any external pressure applied. This will not cause the prize balls to accumulate in the vicinity of the outflow port, and this will not cause the ball catching phenomenon. It is possible to replenish the fuel in an orderly and smooth manner. Moreover, even when the outlet is reduced to almost empty state, the prize ball does not remain in the prize ball tank, and the tilting plate does not catch the ball and stop. Since this is detected, it is possible to completely eliminate the inconvenience of replenishment with a lot of gift balls remaining in the past, and the prize balls stored in the tank are always optimal. It can be detected under various conditions, and the most ideal replenishment is possible.
