Description

[Detailed Description of the Invention] The present invention relates to a prize ball discharging device for a pachinko machine that discharges a certain number of prize balls to an upper supply tray or a lower tray on the front of the pachinko machine each time a batted ball wins a prize.
A control member that moves reciprocally is positioned at the outlet of a collection gutter that collects winning balls, and an operating piece on which winning balls that are individually controlled by the control member acts directly faces above the control member, The prize ball directly activates the prize ball falling mechanism to eject the prize ball.

The conventional prize ball discharging device is equipped with a controller that tilts by the weight of the winning balls, and the controller controls the winning balls one by one, and the controller is connected to the prize ball by a link mechanism or the like. An electromagnetic system that connects to a ball flow down mechanism and discharges winning balls, or electrically detects winning balls that are controlled individually by a controller with a detector, and is excited by a signal from the detector. The prize ball is discharged by operating the prize ball flow down mechanism using the solenoid. In such a prize ball discharging device, a link mechanism or rod for restoring the controller, or a long downflow gutter for timing the prize ball discharge must be attached to the game board. Therefore, the back side of the game board becomes complex with various mechanisms such as the link mechanism and the gutter, and becomes a hindrance to, for example, special game machines that are becoming larger in size these days.

This proposal was proposed in view of the above, and includes forming a receiving part on the upper surface to receive one winning ball, and positioning a control member that moves back and forth by an electric drive source at the outlet of the winning ball collection gutter. The prize ball ejection is controlled by having an actuating piece directly pressed by the winning ball transferred by the control member face the control member, and connecting the actuating piece to the prize ball falling mechanism via a link mechanism. Since the prize ball ejecting mechanism is mechanically actuated by the prize ball, the prize ball ejecting operation is reliable, and the electric drive source, link mechanism, and prize ball storage section are located on one side of the back of the game board. The present invention aims to provide a highly functional prize ball discharging device that can be arranged centrally on one side, simplifying the back mechanism of a pachinko machine, and speeding up prize ball discharge.

The present invention will be explained below based on drawings of embodiments.

The back of the game board 1 of the pachinko machine has a winning ball collecting gutter 2 that collects winning balls, and the winning balls that enter the winning opening (not shown) provided on the surface of the game board 1 are sent to the winning ball collecting gutter 2. The liquid is guided and flows out to the outlet 3 formed at the lower end of the bottom surface 2'. Below the discharge port 3, a semi-circular receiving part 4 is formed on the upper surface, which has a recess shape to receive one winning ball, and has a depth to receive the lower half of the ball in this case. 5 (for example, a motor), the receiving part 4 faces a substantially T-shaped control member 7 that moves in a reciprocating arc around a shaft 6, and when the receiving part 4 is located at the discharge port 3, the flow flows downward from the discharge port 3. The winning ball enters the receiver 4.

The upper half of the winning ball that has entered the receiver 4 protrudes from the upper surface of the control member 7, and moves laterally (to the right in FIG. 1) as the control member 7 moves. Behind the control member 7, a base plate 8 is pivoted to one end on the discharge port 3 side at a height where the winning ball passes, and an actuating piece 9 is positioned with the other end facing above the control member 7. Actuation piece 9
The lower surface of the ball is tilted downward in the direction of movement of the winning ball. Therefore, the winning ball that is moved by the rotation of the control member 7 comes into contact with the lower surface of the actuating piece 9, and gradually pushes up the end of the actuating piece 9 as it advances.

The actuating piece 9 pushed up by the prize ball operates a prize ball falling mechanism 11 connected via a link mechanism 10, and discharges a certain number of balls as prize balls to the player.

As shown in FIG.
0a, and a link member 10b which can be bent into a substantially horizontal T-shape around a movable shaft portion midway along the length is pivoted to the upper end of the connecting member in a substantially T-shape.

The link member 10b has one end pivotally fixed to the base plate 8, and the other end pivoted to one side of a prize ball storage section constituting a prize ball falling mechanism.

On the other hand, since the bottom of the receiving part 4 of the control member 7 is gently inclined downward toward one side, the winning ball that has moved up the actuating piece 9 and activated the winning ball flow down mechanism 11 enters the inlet of the winning ball discharge gutter 12. 12', the ball falls and flows into the winning ball discharge gutter 12, where it is discharged to the outside of the Pachinko machine. The control member 7, which has discharged the winning balls, moves in the opposite direction to complete one stroke and prepares for the next winning ball.

In addition, when the receiving part 4 of the control member 7 is not located under the discharge port 3, the top surface of the control member 7 closes the discharge port 3, so winning balls from the winning ball collection gutter 2 hit the top surface of the control member 7. It will not leak out.

Further, the board 8 is attached to one side of the surface of the collection gutter 2, and the board 8 has a prize ball storage tank 13 and a conduction gutter that allows the prize balls to flow out from the storage tank 13 in one or two rows. 14. A prize ball storage part 15 that communicates with the lead-out gutter 14 as a prize ball flow down mechanism 11. When the prize ball storage part 15 is tilted, a certain number of prize balls existing inside the prize ball storage part 15 are transferred to an upper supply tray or a lower tray on the front side of the pachinko machine. (not shown) Prize ball discharge gutter 16, prize ball storage section 15
A link mechanism 10 for tilting is provided.

If there is a ball in the middle of the lead-out gutter 14, it will turn ON,
The switch mechanism 17 that is turned OFF is connected to the electric circuit of the electric drive source 5, and the outlet gutter 1 is connected to the electric circuit of the electric drive source 5.
The electric drive source 5 can be operated only when the ball 4 has a ball.

As shown in FIG. 1, the prize ball storage section 15 is shown as a gutter-like structure that is pivoted in the middle of its length and has open upper and lower surfaces.
4, the open lower end 15'' is blocked by the blocking piece 18 provided on the upper part of the prize ball discharge gutter 16, and rotates to open the open upper end 15'.
When the open lower end 15'' is blocked by the bottom surface of the tip of the outlet gutter 14, the open lower end 15'' communicates with the prize ball discharge gutter 16.And when the open upper end 15' is blocked, the upper end of the prize ball storage section 15 The extended tongue piece 19 closes the lower end outflow portion 14' of the outlet gutter 14 and prevents the balls from flowing out from the outlet gutter 14.

Therefore, the open upper end 15' is the lower end outflow part 1.
4', a certain amount of balls from the lead-out gutter 14 are stored in the prize ball storage part 15, and when a ball hits a prize and the prize ball storage part 15 is rotated by the link mechanism 10, the balls inside are won. Balls are discharged from the ball discharge gutter 16 to a saucer (not shown) on the front of the pachinko machine. When the prize ball storage section 15 rotates back under the bias of the spring 10' and the open lower end section 15' communicates with the lower end outflow section 14', the balls from the outlet gutter 14 are stored in the prize ball storage section 15.

On the other hand, the mechanism for reciprocating the control member 7 by an electric drive source 5 (for example, a motor) has a receiving part 4 for receiving a ball on an arcuate upper surface centered on a shaft 6, as shown in FIG. At the same time, the lower end of a substantially T-shaped control member 7 having a longitudinally elongated through hole 20 formed below the receiving portion 4 is pivoted to the substrate 8 with a shaft 6,
The pin 22 of the rotating plate 21 is engaged with the through hole 20.

Therefore, the electric drive source 5 operates and the rotating plate 2
1, the pin 22 rotates while moving up and down within the through hole 20, causing the control member 7 to swing left and right about the shaft 6. When the control member 7 swings,
The receiving portion 4 formed on the upper portion moves in a reciprocating arc to the left and right about the shaft 6.

In addition, the winning ball detector 23 is provided on the upstream side of the discharge port 3, and the control detector 24 is placed facing the rotating plate 21 having the stop groove 21', and the winning ball detector 23 and the control detector 24 are connected electrically. Connect to the electric circuit of the drive source 5. Therefore, when the winning ball detector 23 detects a winning ball, the drive source 5 is started, and the control detector 24
When the motor detects the end of one stroke, the drive source 5 is stopped. Therefore, the driving source 5 operates only when a hit ball wins, so power consumption is low and it is economical.

Next, to explain the operation of the above-mentioned prize ball ejecting device, the winning balls are received by the collection gutter 2, and roll toward the discharge port 3 due to the downward slope of the bottom surface 2'.
It fits into the receiving part 4 from the discharge port 3. At this time, the winning ball detector 23 turns ON due to the winning ball, so
The electric drive source 5 starts and the rotary plate 21 rotates,
Since the stop groove 21' moves, the control detector 24
It becomes ON. Therefore, even if the winning ball detector 23 changes from ON to OFF, the electric drive source 5 continues to operate, and the receiving part 5 continues to accept winning balls due to half a rotation of the rotary plate 21, and ejects the winning balls. Move to a position facing the inlet 12' of the gutter 12.

As the above-mentioned movement of the receiving part 4 causes the upper end of the winning ball protruding from the upper surface of the control member 7 to gradually push up the lower surface of the actuating piece 9, the connection pivoted to one end of the actuating piece 9 is moved. Raise the member 10a. Therefore, the movable shaft portion of the link member 10b that is pivotally attached to the upper end portion of the connecting member 10a rises,
The link member 10b is bent horizontally around the movable shaft portion as shown by the dashed line in FIG. The required prize balls are ejected.

Moreover, when the receiving part 4 is located at the inlet 12' of the winning ball discharge gutter 12, the winning balls in the receiving part 5 will not roll down because the bottom of the receiving part 4 is gently sloped down toward one side. , and flows out into the winning ball discharge gutter 12. When the winning ball flows out, the operating piece 9 rotates back under its own weight and lowers the connecting member 10a, so the link member 10b
becomes straight as before, and the prize ball storage section 15 is tilted back to be in the state of replenishing the prize balls.

On the other hand, the remaining half rotation of the rotary plate 21 returns the receiver 4 from which the winning balls have flowed out to the position facing the discharge port 3, making it ready to receive the next winning ball. One stroke of each movement is completed. When the rotary plate 21 rotates once, the stop groove 21' of the rotary plate 21 faces the control detector 24, so the control detector 24 changes from ON to OFF and the electric drive source 5 stops.

Furthermore, in the above-described embodiment, even if the winning ball detector 23 is turned on by fraudulent means by the player or the electric drive source is activated due to malfunction, if there is no winning ball in the receiving section 4, , there is no risk of the prize ball being ejected. Furthermore, even if the player attempts to illegally manipulate the prize ball storage section 15 with a piano wire or the like, the link member 10b will act as an obstacle and the prize ball storage section 15 will not tilt, so the prize balls will not be ejected. .

In addition to the above embodiments, the mechanism for reciprocating the control member 7 may be constructed by connecting the end of the control member 7 and the pin 22 of the rotating plate 21 with a connecting rod to form a link member. In either case, when the rotating plate 21 rotates once, the control member 7 moves back and forth, takes out one winning ball from the discharge port 3, and discharges the winning ball.

Further, in the above-described embodiment, the control member 7 is positioned below the discharge port 3, but the present invention is not limited to this, and the discharge port 3 may be opened laterally.

As explained above, according to the present invention, since the prize ball storage section is mechanically actuated by the batted ball received in the receiving section, the ejection operation of the prize ball is ensured, and moreover, the electric drive source is not required. Even if it is activated due to malfunction, if there is no winning ball in the receiving part, the winning ball will not be ejected, and a highly reliable winning ball ejecting device can be provided.

In addition, since the prize ball storage section is tilted by a link member that can be bent from the middle of its length, it is difficult for players to try to manipulate the prize ball storage section using illegal means such as piano wire or thin wire. Also, the link member does not become an obstacle and the prize ball storage section does not tilt, which is also effective from the standpoint of preventing fraud.

Furthermore, since the actuating piece is inclined downward in the direction of movement of the winning ball, it is possible to increase the operating stroke of the connecting member and link member by comparing the amount of movement of the winning ball. The movement of the control member can be reduced, and the return operation of the control member can be made quickly.
