Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a safe ball control device for a pachinko machine that detects a ball that has entered a prize opening and becomes a safe ball, opens a prize ball case, and controls the release of a predetermined number of prize balls. It is related to.

As is well known, pachinko machines have a safe ball detection system to ensure that when multiple balls hit are safe balls at the same time or consecutively, a prize ball determined for each safe ball is released. It is equipped with a detector and a controller that accurately activates the detector in a number corresponding to the number of safe bulbs.

Normally, this safe ball detector and safe ball controller are placed in an interlocking relationship, and when the controller sends out one safe ball, the safe ball detector will surely open the prize ball case once. In order to ensure that a certain number of prize balls are accurately released for each safe ball, some kind of regulating means is provided between the two to prevent the controller from automatically sending out the next safe ball while this detector is in operation.
In other words, a restraining member is usually inserted to restrain the operation of the controller.

The present invention includes a restraining member inserted between the safe sphere controller and the safe sphere detector, and the restraining member is released by an operation other than the release method using the safe sphere detector, and the safe sphere controller is returned to its original state. It is an object of the present invention to provide a new safe ball control device equipped with a release member that can be returned to the original position.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Figures 1 to 3 are rear views showing the mutual operational relationship between the safe ball control device and the prize ball device facing the safe ball path, Figure 4 is an enlarged rear view of the main parts, and Figure 5 is a rear view of the main parts.
7 to 7 are enlarged front views of main parts, partially in section, showing mutual relationships centering on the restraining member during operation.

Reference numeral 1 in the figure indicates a mechanism frame configured to incorporate a safe ball control device according to the present invention and a prize ball device that is linked to this control device and releases a prize ball,
Reference numeral 2 denotes a board that serves as the framework of a mechanism frame provided for equipping or assembling various built-in devices, and reference numeral 3 designates the back side of this board 2 (the front side when viewed from the front of the pachinko machine). Safe ball passage integrated into the surface,
4 is a safe ball controller facing the upper folded part of this safe ball passage, and 5 is a swinging tip whose part of the length near the rear end 5' is pivoted to a support shaft 6 implanted in the board. This is a safe ball detector with a receiving part 7 facing the arc-shaped safe ball passage 3. Reference numeral 8 connects the lower end to the rear end 5' of the detector, and the upper end is attached to the top of the board 2 with a support shaft 9. This is an interlocking rod that is connected to the actuating plate 10, which is freely supported by the actuating plate 10, and is passed between the two. The parts indicated by broken lines in FIGS. 1 to 3 are devices installed on the front side of the board 2, and 11 is a guide path for guiding prize balls to the prize ball device, and 12 is a guide path provided following this guide path. Prize ball case, 13 is a lid member that closes the exit of the prize ball case, 14 is a door member that closes the entrance, and 15 is a prize ball discharge path that guides the prize balls released from the prize ball case to a prize ball tray (not shown). .

Although the mechanism frame 1 housing these various devices is not shown, it is assembled so that the back side of the board 2 faces the back side of a base frame board provided inside the pachinko machine. A frame 16 provided continuously above the safe ball passage 3 in contact with the back surface of the base frame plate constitutes a ball collection frame of the safe ball collection chamber. When a safe ball flies into the ball collecting chamber from the prize opening of the game board, this ball collecting frame 16 guides it and sends it into the safe ball passage 3.

Now, in the normal state of the device of the present invention, the safe ball detector 5 is in the state shown in FIG. Then, the actuating plate 10 is pulled down, and the pin 18 protruding from the lid member 13 of the prize ball case 12 is hooked to the notch engaging portion 17 to be restrained in the closed state, and the prize ball from the guide path 11 is released. It is stored in the case 12.

In this state, when a batted ball enters the safe ball collection chamber from the prize opening of the game board, the ball enters the receiving part 4a of the controller 4 facing the bending part of the passage 3, and this controller swings around the shaft 19 as a fulcrum. The ball is tilted forward and downward, and the ball rides on the swinging piece 4b and flows down the main stream of the safe ball passage that continues below the bending part.

The safe ball A in FIG. 1 is located just before entering the receiving portion 4a, and the controller 4 is in a forward upward position due to the action of the weight 20. FIG. 2 shows that the safe ball A is received on the receiving part 4a, tilting forward, lowering the swinging piece 4b, and riding on the receiving part 7 of the safe ball detector 5 facing the safe ball passage 3, and holding the safe ball A. The figure shows it being pushed down with the weight of . At this time, as will be described later, the lowered swinging piece 4b is latched onto the hook of the restraining member and is prevented from rising, thereby causing the stopper piece 4c of the controller 4 to move as shown in the figure. is projected into the bending part of the passageway 3 to prevent the subsequent safe ball A from flowing down.

When the safe ball A pushes down the receiving part 7 in this way, the detector 5 swings about the support shaft 6, and guides this ball to the lowest end of the passage 3 and releases it from the passage. With this swinging, the interlocking rod 8 is pushed up, causing the actuating plate 10 to swing upward.
The pin 18 comes off from the engaging portion 17, and the lid member 13 of the prize ball case is released.

For this reason, the prize ball release path 15 of the ball in the prize ball case
At this time, the arm 21 of the door member 14 connected to the actuating plate 10 is released at the same time as the lid member 13 is opened.
swings to push the door member into the prize ball guiding path 11 and stop guiding the prize balls, so that only a fixed number of prize balls in the prize ball case are released.

FIG. 3 shows that the pin 18 is disengaged from the engaging portion 17 of the actuating plate 10 due to the swinging of the detector 5, and the prize ball case 12 is removed.
The safe ball A riding on the receiver 7 of the detector pushes this receiver down to the lowest end of the passage 3, and then moves out of the passage and prevents the detector from being pushed down. release. Then, the released detector returns to the original state shown in FIG. 1 under the weight of the interlocking rod 8 acting on the rear end 5', and is ready for the next safe ball to flow down. Incidentally, FIG. 4 shows a state in the middle of recovery.

The controller 4 and the detector 5 operate in the relationship described above,
Prize ball case 1 is awarded when one safe ball A passes.
2 is opened once, but a new safe ball does not flow into the safe ball passage 3 during the one-stroke movement from when the detector 5 that activates the actuating plate 10 of the award ball case descends until it rises. The controller 4, which controls the flow of the safe balls, stops the flow by placing the stopper piece 4c facing the bend in the passage.

FIG. 4 correctly shows this state, in which the controller 4 is restrained by a restraining member 22 provided on the front side of the board 2.

The restraining member 22 is a rocking plate 22 that is freely rockably supported on a support shaft 23 implanted in the base plate 2 shown in FIGS. 5 to 7.
a, a hook member 22b that is provided so as to project upward from the common support shaft 23, and an arc-shaped sliding member 22c that is pivotally connected via a shaft 24 so as to project from the side of the rocking plate. Ru. Swing plate 22a
normally hangs down below the support shaft 23 due to its own weight, and the upper hook member 22b causes the weight piece 25 to abut against a stopper 26 provided on the rocking plate to raise the hook piece 27, thereby causing the controller 4 to A long hole 29 opened in the substrate 2 through which the pin 28 protruding from the swinging piece 4b passes.
Wait for the pin 28 to come down. and,
The sliding member 22c faces a guide hole 30 opened parallel to the arc-shaped safe ball passage 3, and slides into a pin 31 implanted near the tip of the detector 5, which moves up and down along the guide hole. One side of the hanging lower end is always in contact with a stopper 32 provided on the swing plate 22a, and the convex arc edge of the other side is made to cross the guide hole 30.

FIG. 5 is a diagram corresponding to the above-mentioned FIG.
The pin 31 of the detector 5 is located at the upper end and is not engaged with the hook member 22b, and also passes through the guide hole 30.
is also in the raised position and in a non-engaged state.

In this state, when the safe ball A enters and the controller 4 tilts forward as described above and its swinging piece 4b descends, the pin 28 also lowers and engages the hook member 22b waiting along the elongated hole. do.

Therefore, the controller 4 is restrained in a forward tilted position, and its stopper piece 4c faces the passage to prevent the following safe ball A from flowing down. FIGS. 2 and 6 show this state.

Then, the safe ball A that has oscillated the controller pushes down the detector 5. At this time, the pin 31 passed through the guide hole 30 slides into contact with the concave arc edge on the other side of the sliding member 22c, and as shown in FIG. 6, the pin 31 swings to the left and continues along the guide hole. He was then allowed to descend.

Next, as described above, when the detector 5 descends and the ball of the receiving part 7 is moved out, it moves back up and back, but at this time, the pin 31 that ascends the guide hole 30 again comes into contact with the sliding member 22c. become.

Unlike when descending, the pin 31 during this upward movement collides with the convex arcuate edge of the other side of the sliding member 22c. Since the sliding member receiving the pin 31 cannot independently swing to the right due to the stopper 32, the swinging plate 22a is pushed to the right together with the swinging plate 22a, and swings around the support shaft 23 (Fig. 7). reference). For this reason,
The hook member 22 is pivoted about this support shaft 23 as a fulcrum.
Since the hook b also swings together with the swing plate 22a via the stopper 26, the hook piece 27 is retracted from the elongated hole 29, and the pin 28 of the controller 4 that is engaged with the hook piece 27 is released.

Therefore, when the detector 5 moves upward and returns, the restraining member swings about the support shaft 23, and the controller 4 also returns to its original state, and the new safe ball that was stopped by the stopper piece 4c will be allowed to pass.

By sequentially repeating the above process, one prize ball release operation is performed for one safe ball,
The correct prize ball will be released.

In the figure, reference numeral 33 denotes a hook member to prevent the detector 5 from returning to the uppermost position when it reaches its lowest position.It is provided to swing around a shaft 34 as a fulcrum, and when the detector 5 reaches its lowermost position, Therefore, when the pin 31 descends through the guide hole 30, it is hooked to the hook 35 to prevent it from rising.
When the safe ball A riding on the receiver part 7 of the detector moves away from this and moves out of the road, this ball hits the footboard piece 3.
6 is pushed down to disengage the hook 35 and allow the detector 5 to rise freely.

In this way, the safe sphere controller 4 and the safe sphere detector 5
are related to each other so as to make accurate rocking movements through the insertion of the restraining member 22, but when the game is stopped, the prize ball is removed from the prize ball case,
Alternatively, when the pachinko parlor starts operating for the first time, the controller 4 tilts forward and engages the pin 28 with the hook piece 27 of the restraint member 22, regardless of the delivery of the safe ball. If this happens, there will be no means to return the controller to its original state since the detector 5 will not be subject to rocking motion.

In particular, the devices that control the release of these prize balls are the central part of a pachinko machine and are at high risk of being fraudulently exploited, so they are actually sealed inside the frame. , the detector is usually constructed so that it cannot be easily operated from the outside.

In the drawing, 37 indicates a hook piece 27 for releasing the restraint state of the restraint member 22 in such a case.
This is a release member provided near the.

As shown in detail in FIGS. 8A and 8B, this release member 37 is pivotably pivoted on a support shaft 38 implanted in the base plate 2, and is located on one side of the hook piece 27 of the restraint member 22, and is always The contact piece 40 is kept separated from the hook piece 27 by the weight of the weight plate 39 provided integrally therewith.

On the other hand, the knob piece 41 extending upward is a small window 4 formed in a cover piece 42 that covers the entire restraining member.
3 and protrudes upward so that it can be swung by finger operation.

As mentioned above, this release member is normally in a hanging state, and the contact piece 40 is separated from the hook piece 24 so as not to interfere with the release operation of the restraining member by vertical movement of the safe ball detector 5. Then, the safe ball controller 4 swings forward and downward, regardless of the delivery of the safe ball, causing the pin 28 of the swinging piece 4b to engage with the hook piece 27, and as the detector 5 rises, the safe ball controller 4 swings downward. If there is no way to release the button, tilt the knob 41 protruding from the small window 43 in the direction of the arrow and press the contact piece 40 against the hook piece 27 using the support shaft 38 as shown in FIG. 8B. Often, the restrained pin 28 will easily come off, and the controller 4 will return to its original state under the action of the weight 20, waiting for the safe ball to flow in.

The present invention has been described above with reference to the illustrated embodiments, but the present invention device has a controller that sends safe balls into a safe ball path, and a detector that receives safe balls passing through this path and activates a prize ball device. Accurate operation can be expected because it is configured to ensure that one prize ball is ejected once for each safe ball by interlocking through the members,
In response to the possibility that the controller is self-restricted and stops operating due to the interposition of this restraint member, the controller is configured to be able to be released from the restraint state at any time by providing a release member that releases this restraint. Therefore, troubles caused by the restraining member can be completely eliminated. Moreover, the above-mentioned release member is extremely easy to release because it can be operated by pushing down the knob, and this knob protrudes to the outside through a small window in the cover, so that safe ball detection is performed each time it is operated. This is also advantageous in terms of crime prevention since there is no need to open the inside of the device.
