[Detailed description of the invention] This invention automatically stops the prize ball discharging operation when a prize ball is missing in the prize ball supply gutter that feeds the prize ball into the prize ball case, and releases the empty prize ball. The operating range is to provide a prize ball stopping device for a pachinko machine that prevents the ejection of missing prize balls.In particular, this device reliably detects the presence or absence of prize balls in the prize ball supply gutter. To provide a prize ball stopping device which allows accurate stopping operation to be expected.

Hereinafter, the present invention will be explained with reference to the illustrated embodiment, and its features will be detailed. 1 is a base frame body, 2 is a prize ball supply provided horizontally with a downward slope on the upper part of the base frame body. The gutter 3 is a prize ball gutter installed vertically via the meandering part 4 following the supply gutter 2, 5 is a prize ball case installed in the middle of the prize ball gutter, and 6 is the lower part of the prize ball case. Outflow control door that opens and closes the opening, 7
Reference numeral 8 indicates an inflow regulation door that opens and closes the upper opening of the prize ball case, and 8 indicates an opening/closing operating member that operates both regulation doors. Reference numeral 9 denotes a detection device that detects the presence or absence of prize balls sent through the prize ball supply gutter 2 and controls the prize ball discharge operation of the prize ball case.

The base frame body 1 and prize ball supply gutter 2 shown here,
The prize ball gutter 3 is integrally molded from plastic, and can be assembled integrally by attaching the base frame 1 to the back of the pachinko machine main body.

The base frame body is made up of two parallel plates, front and back, and the supply gutter 2 and prize ball gutter 3 are formed by passing a rib-shaped partition wall between these two plates.

The supply gutter 2 is configured to receive prize balls A by connecting its upper opening to a supply pipe (not shown) provided outside the pachinko machine, and the prize balls are directed toward the right side of the figure according to the slope of this gutter. The ball flows leftward through the meandering portion 4 into the prize ball gutter 3 and is sent to the prize ball case 5.

The prize ball case 5 is incorporated so as to constitute a part of the prize ball gutter 3. Here, the case body is formed as a cylinder, and mounting ears 10 provided at the upper end of the cylinder are attached to the front and rear of the base frame. It is attached by being pivoted to a shaft 11 passing between the plates. In this prize ball case, the upper end opening of the tube communicates with the prize ball gutter 3 so that the prize balls A always flow in, and the lower end opening communicates with the prize ball gutter 3 below when in normal condition. The prize ball that has been accepted is placed inside the prize ball case so that it can be sent out.

In addition, this prize ball case 5 has a pin 1 provided at the lower end.
A stopper 14 is provided on the rear plate of the base frame and protrudes outward through a window 13 formed in the base frame.
When the stopper 14 is released, it swings about the shaft 11 and moves the lower end opening into the prize ball gutter 3.
It communicates with a ball extracting gutter 15 arranged in parallel with the ball extracting gutter so that the prize balls received inside can be discharged into this ball ejecting gutter.

The outflow restriction door 6 is a door that stops the outflow of prize balls received inside when the prize ball case 5 is in a normal state, and the inflow restriction door 7 stops the flow of subsequent prize balls when this outflow restriction door is opened. The opening/closing member 8 controls these two doors.

The actuating member 8 has a cloud-shaped plate shape, and is mounted so as to swing freely by having one end thereof pivoted by a support shaft 16, and a connecting rod connected to a safe ball detector (not shown) is attached to the free swinging end. 17 are connected. and,
A notch-shaped locking portion 18 is provided at the lower edge of this member, and a pin 19 provided at the lower end of the outflow restriction door 6 is engaged with this locking portion, and the upper edge A vertically elongated hole 20 is provided near the section, and an arm 2 extending downward of the inflow regulating door 7 is inserted into this elongated hole.
A pin 22 provided at the tip of one is slidably fitted.

When the safe ball detector does not operate, the operating member 8 lowers its swinging free end by pulling down the connecting rod 17, and locks the pin 19 of the outflow restriction door 6 into the locking portion 18.
This outflow regulation door is held in a closed position (the state shown by the broken line in the drawing) by engaging with the outflow regulation door to prevent the prize balls from flowing down, and at the same time, the outflow regulation door is provided on the arm 21 of the inflow regulation door 7 which is pivotally connected by a support shaft 23. By moving the pin 22 to the left, the stopper piece 24 provided at the upper end of this regulation door is moved back from the window 25 formed in the middle of the prize ball gutter 3, thereby allowing the prize ball gutter 3 to pass freely from the supply gutter 2. This allows the prize ball A to flow into the prize ball case 5,
At this time, a certain number of prize balls are stored in the prize ball case. Next, when the safe ball detector is activated by the entry of the safe ball and pushes up the connecting rod 17, the pin 19 comes off from the locking part 18, and the weight of the prize ball stored in the case causes the outflow control door to open. is pushed open, so the stored prize balls are released into the prize ball gutter below, and at the same time, the pin 22 of the inflow regulating door 7 is moved to the right, and the stopper piece 24 uses the support shaft 23 as a fulcrum to pass through the window 25 and release the prize ball. In order to enter the inside of the ball gutter 3 and stop the flow of prize balls, only a constant number of prize balls stored in the case are released through the prize ball case 5, and subsequent balls wait at the entrance of the case. Become.

This release of the prize ball is instantaneous as the ball flows down. As the operating member 8 returns to its original state, the inflow regulating door 7 opens and the prize balls flow into the prize ball case 5, and at the same time, the outflow regulating door 6, which was pushed away by the outflow of the balls, closes at the upper end due to its own weight. Swings around the support shaft 26,
The pin 19 at the lower end engages with the locking portion 18 of the operating member, and the incoming prize balls are stored in the prize ball case, and are prepared for the next prize ball release.

The detection device 9 includes a detection plate 28 having a swinging piece 27.
and a swing plate 29, and the detection plate 28 faces the gutter through a window 30 cut out in the upper surface of the prize ball supply gutter 2. Note that this detection plate 28
If a convex portion is provided in an upright manner on the upper surface of the swinging free end of the gutter 2, that is, the swinging side free end facing the edge of the window 30 of the gutter 2 so as to come into contact with it from below, the protrusion does not abut the edge of the window. , it is possible to prevent the ball from flying up and being bitten by the upper surface of the swinging free end when the detection plate falls.

This detection plate 28 has one end supported on a support shaft 31, and its swinging free end protrudes in the downstream direction of the gutter 2, and the swinging free end is always dropped into the gutter by its own weight. The piece 27 is arranged to stand up substantially at right angles from the upper surface of the detection plate on the shaft bearing end side.

On the other hand, the swing plate 29 is supported in the middle of its length by a support shaft 32 so that both ends can swing up and down. A connecting rod 36 connected to the opening/closing member 8 is pivotally connected to the other swinging end 35 facing the side edge.

When the supply gutter 2 is filled with prize balls, the detection plate 28 receives the prize balls and is pushed upward, as shown in FIG. The swing piece 27 provided on the top surface is maintained in a vertically erect state. At this time, the engagement pin 34 provided at one end of the swing plate 29 separates from the swing piece 27 and can freely swing up and down along its side edge.

For this reason, when the prize ball supply gutter 2 is filled with prize balls and the prize ball case 5 is continuously being replenished with prize balls, the swing plate 29 freely swings as the detection plate rises. Therefore, when the opening/closing operation member 8 swings by pushing up the connecting rod 17 due to the entry of the safe ball, that is, when releasing the prize ball from the prize ball case 5, it operates without any restraint. However, when there are no more prize balls in the supply gutter 2, the detection plate 28 is released from being pushed up by the prize balls as shown in Figures 2 and 3, and its free end is released into the gutter. Since the rocking piece 27 is tilted toward the rocking plate 29 side, the rocking plate 29 causes the engagement pin 34 at one end of the rocking plate 29 to abut against the rocking piece 27, and free rocking is prevented. It turns out. As a result, the opening/closing member 8 connected to the rocking plate 29 through the connecting rod 36 is automatically restrained from swinging and stops ejecting the prize ball.

The device of the present invention is constructed as described above, and when prize balls are continuously supplied through the prize ball supply gutter 2 and the inside of the prize ball supply gutter in front of the prize ball case is filled, the detection plate 28 In order to enable the swinging piece 27 to swing freely on the swinging plate 29 without interfering with the swinging plate 29 by pushing up, the opening/closing member 8 connected by the connecting rod 36 is operated. The ball becomes free and the prize balls in the prize ball case can be ejected each time as the safe ball detector operates, but when there are no prize balls inside the gutter 2, the push-up of the detection plate 28 is released and the ball oscillates. Since the plate 29 is locked, the prize ball case 5 will not be opened even if the safe ball detector detects the ball, and the release of prize balls will be automatically stopped.

Therefore, according to the device of the present invention, if prize balls are not replenished, empty prize balls will not be ejected even if a safe ball flies in, and the missing prize balls that are less than the constant number will not be released. The troubles caused by these malfunctions can be eliminated before they occur without the need for discharge.

In addition, the detection plate 28 in the device of the present invention is pushed up by the prize balls during normal conditions when the prize balls are replenished, ensuring free rocking of the swing plate 29; When the ball is missing, it is inevitably released from this push-up and the swinging piece 27 is engaged with the swinging plate 29 and restrained, so it is possible to accurately check the presence or absence of prize balls inside the supply gutter 2. detection, and therefore reliable operation can be expected. In addition, the detection plate in the device of the present invention is attached to the top surface of the prize ball supply gutter, and since the size of the prize ball is the object of detection, the bottom surface of the supply gutter is left flat, and it is possible to detect equal pitches with steps. Since it does not obstruct the flow, there is an advantage that even if it is placed in the middle of the length of the gutter, it can be smoothly replenished without interfering with prize balls.
