Description

[Detailed explanation of the invention] This invention is based on the winning device of pachinko machines,
More specifically, the present invention relates to a prize-winning device that closes a door that is openable and closable at the entrance of a prize-winning device when a set number of safe balls is counted.

Previously, this type of device closed the door when the electromagnetic solenoid connected to the safe bulb count switch and other switches was turned off, and the solenoid was turned off.
It is configured to open the door when the solenoid is turned ON, and once the door is opened by the activation of the solenoid, the solenoid is then energized for a predetermined period of time to maintain the ON state and keep the door open. There must be. As a result, the actual operating time of the solenoid increases each time it is activated, causing the solenoid itself to deteriorate quickly due to seizure (thermal damage), resulting in the problem that the door cannot open and close properly. .

In order to solve the above conventional problems, the present invention
The door of the winning machine is configured to be opened and closed by an opening/closing mechanism that can be operated by separately using a specific ball generated in another part (for example, a safe ball) and an electromagnetic solenoid connected only to the counting switch. This is a prize-winning device, and its purpose is to shorten the actual operating time of the electromagnetic solenoid to prevent it from becoming obsolete prematurely, to open and close the door normally over a long period of time, and to improve the interest of the game.

Embodiments of the present invention will be described below with reference to the drawings.

In this example device, an opening/closing mechanism 1 set on the back side of the game board G is attached to a winning device 1 installed below the game surface.
2 are installed in succession. The winning device 1 is also commonly referred to as an "attacker accessory", and has a door 4 attached to the safe ball entrance 3 in the center of the main body 2 so that it can be opened and closed back and forth with a shaft 5, and Attach the detection switch 8 for the safe bulb to the detection piece 9.
is made to face an outlet 10 opened on the back surface of the main body 2. Note that the door 4 is always biased in the open (forward) direction due to its own balance, and is held in the open state by the stopper pieces 6 on both sides. Further, since the switch 8 is connected to a count circuit (both not shown) in the control circuit, it is also referred to as a count switch for convenience. Reference numeral 11 denotes an opening/closing lever pivotally mounted on the back side of the main body 2, whose front end extends into the main body 2 and is connected to the connecting piece 7 of the door 4;
The door is restrained in the upright and closed state when tilted downward, and released when tilted upward.

On the other hand, the opening/closing mechanism 12 includes a ball receiving lever 15, a lock piece 2, and a case 13 that is removably set on the back surface of the game board G above the above-mentioned winning device 1.
0, the operating lever 24 and the electromagnetic solenoid 31 are assembled into a single unit to operate the opening/closing lever 11. That is, the ball receiving lever 15 is mounted on the shaft 14 to the case 13.
is always biased clockwise by a weight 16 at its rear end (right end in the figure), and the case 13
The tilting amount and state are regulated by the stopper 17 on the side, and the ball receiving part 18 at the front end (left end in the figure) is
It faces a predetermined position in the path 19 of a safe ball (SB) generated by another winning device (not shown).
A locking piece 20 is formed integrally with the ball receiving lever 15. This lock piece 20 forms a guide part 21 and an engagement port 22 for a pin 26 of an operating lever 24, which will be described later, and is made to be able to swing together with the lever 15 about the shaft 14 as a fulcrum, and is normally kept balanced in a hanging state. has been done.

An operating lever 24 with a shaft 23 attached to the case 13
is always biased counterclockwise by a weight 25 at its front end, and has an engagement pin 26 for the lock piece 20 attached to its front end, and an opening/closing lever 11 of the award machine 1 at its rear end. The operating rod 27 is articulated and hangs down.

By the way, the lever 24 is normally the lock piece 2.
0, the opening/closing lever 11 is held in a depressed state by the operating rod 27. Note that the vertical weight 25 of the lever 24 can be displaced using a long hole 28, so that the balance of the lever 24 itself can be adjusted. Further, the operating rod 27 is inserted and supported by a holder 29 provided in the case 13, so that the opening/closing lever 11 can be operated appropriately. 30 is a stopper for the operating lever 24.

The electromagnetic solenoid 31 is connected to the count switch 8 mounted above the operating lever 24.
electrically connected to. This solenoid 31
Normally, the lever is in a rest (OFF) state and the rod 32 is retracted above the rear end of the lever 24.
When the count switch 8 counts a set number, it is energized (ON) to lower the rod 32 and push the lever 24 back to its original position. 33 is the main body of the back mechanism.

Therefore, in the winning device of this example, the opening/closing mechanism 12 is
The door 4 of the winning machine 1 can be opened and closed by individually utilizing the safe bulb generated in another winning machine and the electromagnetic solenoid 31 for opening/closing operation. That is, in the opening/closing mechanism 12, the ball receiving lever 15 is
The lock piece 20 receives the safe ball (SB) and is tilted by its weight as shown in the imaginary line.
is also swung in the same direction, and the pin 26 of the operating lever 24
to release. Immediately in response to this, the operating lever 24
Tilt the operating rod 2 to the specified position as shown in the imaginary line.
7 to release the opening/closing lever 11 of the winning machine 1. As a result, the lever 11 receives part of the biasing force of the door 4 and is tilted upward, causing the door 4 to fall forward and open the entrance 3. The ball receiving lever 15 and the locking piece 20 are both returned to their original positions, and the operation lever 2
4 is maintained in an inclined state. Therefore, even if a safe ball (SB) occurs again, the ball receiving lever 15
And the lock piece 20 is virtually idle only by being swung once.

When the ball falls onto the door 4 which is opened as described above, it enters the entrance 3 and flows out as a safe ball through the exit 10 to the back side. At this time, the count switch 8 detects each safe ball (ON) and takes a count. When the detection operation of the switch 8 reaches a set number of times, in other words, when a set number of safe balls are generated, the electromagnetic solenoid 31 is energized (ON) and the rod 32 is pushed down. As a result, the operating lever 24 is pushed back, and in the process of swinging back, the operating rod 27 is pushed down and the opening/closing lever 11 is pushed down.
While restraining the lock piece 20 in a downwardly inclined state, the pin 26 is in contact with the guide portion 21 of the lock piece 20, and the lock piece 2
0 is once pushed back to engage the engagement opening 22, and the lever 24 is automatically locked in its original horizontal position.

As a result, the door 4 is restrained in the original upright state with the entrance 3 closed, and thereafter the opening/closing mechanism 12 is held in the same manner as described above.
It is opened and closed using.

In particular, in this example device, the opening/closing mechanism 12 is connected to the case 13.
Since it is constructed in the form of a cassette and can be handled as a unit, it can be easily attached to the winning machine 1. Note that the device to which the present invention is directed may be configured so that the operating rod 27 of the opening/closing mechanism 12 can be directly connected to the connecting piece 7 of the door 4.

As described above, the winning device of the present invention includes a winning machine having an opening/closing door, and an opening/closing mechanism that is individually operated by a specific ball and an electromagnetic solenoid, and the opening/closing mechanism is operated to the open state by the specific ball. The device is configured to open the door and then close the door when the opening/closing mechanism is activated to the closed state by the operation of the electromagnetic solenoid corresponding to the detection of the set number of times of the switch for safe bulb counting. The doors can be opened and closed using specific spherical electromagnetic solenoids.

Therefore, the above-mentioned electromagnetic solenoid is used only when closing the door, and its actual operating time is extremely short, just enough to return the operating lever to its original state, so the solenoid may be damaged by heat and deteriorate prematurely. The durability and lifespan of the door can be increased by eliminating damage and breakdowns, allowing the door to open and close favorably over a long period of time, allowing the game to be enjoyed comfortably. Moreover, according to the present device, the detection switch for initially opening the door and the technology for connecting the switch to the above-mentioned solenoid can be eliminated, so the configuration can be made simpler.
