Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to a first state in which the movable wing pieces are almost upright and a ball flowing down the game board enters only from above;
This winning device is capable of converting to a second state in which when a ball is hit in the state, the movable wing pieces tilt laterally and a ball can be hit from above and from the side, and especially when changing between the above two states. Generate output from the switch mechanism as winning information, operate other devices with this winning information, and
The present invention relates to a winning device for a pachinko machine that prevents illegal games due to magnetism.

(Prior art) There is a first state in which the two opposing movable wing pieces are almost upright and a ball can only be hit from above, and in this first state when a ball is hit from above, both movable wing pieces move laterally. A winning device for a pachinko machine that tilts and converts to a second state in which a ball can be hit from the side has been known.Also, a winning device for a pachinko machine that is equipped with a switch to turn on a lamp or the like has been known. is also known from Japanese Utility Model Application No. 60-37372 by the present applicant.

In the conventional winning device described above, the movable wing pieces change from the first state to the second state.
When the second state is changed, the switch mechanism that was in the off state becomes on state, and as long as the second state continues, the switch mechanism remains in the on state and a decorative lamp or the like is lit. When a ball hits the space between the movable blades in the second state and the state is changed to the first state, the switch mechanism is turned off and the above-mentioned decorative lamp goes out.

(Problems to be Solved by the Invention) Therefore, in the batted ball winning device having the above-mentioned configuration, the switch mechanism only turns on and off depending on the state change of the movable blade, and at most lights up or blinks a lighting device such as a lamp. Therefore, each time a ball hits the winning device, an output is generated and cannot be used as winning information for starting other winning devices or gaming machines. Furthermore, since a magnetically sensitive switch is used as the switch mechanism, there is a risk of fraudulent gaming in which a magnetic field is applied from the outside to illegally generate winning information and illegally gain profits.

Means for Solving the Problems> The present invention was proposed in view of the above, and includes a front frame with an open top surface provided on the front surface of a mounting board fixed to the surface of a game board, and two panels installed in the front frame. The movable wing pieces are supported rotatably in a facing manner, and a swinging bottom plate is provided rotatably in the vertical direction within a guide frame provided on the back surface of the mounting board, and the tip of the swinging bottom plate is connected to the movable wing. In the first state where the movable wing pieces face downward from the opposing spacing between the blades and the ball enters only from above with both movable wing pieces being substantially upright, when a ball enters from above, the tip of the swinging bottom plate will move upward due to the rolling of the ball. The swinging movement of the swinging bottom plate causes both movable wing pieces to tilt laterally, converting the ball into a second state in which the ball can be hit from above and from the sides. When the ball enters between the movable wing pieces, the weight of the ball presses the two movable wing pieces, and the swinging bottom plate pivots so that its tip faces downward, converting it to the first state. The bottom plate constitutes a switch mechanism that turns on and off in relation to each rotational movement of the swinging bottom plate, and is also provided with a magnetically sensitive element that is sensitive to external magnetic force and an abnormality detection resistor, and is provided with a switch mechanism that turns on and off in relation to each rotational movement of the swinging bottom plate. In both cases when converting from the first state to the second state and when converting from the second state to the first state, the output from the switch mechanism is processed as a winning ball detection signal, and this winning ball detection signal is used as a winning ball detection signal. In addition to activating other devices provided on the game board as information, the sending of the winning information is also stopped in the event of magnetic action from the outside, incorrect wiring, disconnection, or the like.

The ball winning device l of the present invention has a mounting board 2 that is attached to the surface of a game board (not shown), and a front frame 3 whose upper surface is open is provided on the front surface of the mounting board 2. The movable wing pieces 5 are pivotally mounted on the left and right sides by shafts 4 so as to face each other. Therefore, each movable wing piece 5 is supported so as to be able to rotate between an upright state and a laterally tilted state using the shaft 4 as a fulcrum.

The above-mentioned mounting board 2 is provided with a batted ball passage hole 6 and a batted ball guiding frame 7 is extended on the rear surface, and within this guiding frame 7, a guiding bottom plate 9 is supported by a support shaft 8 so as to be able to pivot in the vertical direction. death,
The leading end 10 of the guide bottom plate 9 is made to face from the passage hole 6 into the space between the two movable blades 5 in which they face each other. This guide bottom plate 9 is the guide frame 7.
If the inside is almost horizontal yE, the tip part 10 is both movable wing pieces 5
Since the movable wing pieces 5 are located below the facing interval, they are in a substantially upright shape, and are in the first state in which a ball can only be hit from above. In this first state, when a ball enters between the movable wing pieces 5 from above, the ball rests on the guide bottom plate 9 and rolls within the guide frame 7, and when it passes through the support shaft 8, its own weight pushes the guide bottom plate 9 toward the tip. Rotate so that the part 10 faces upward. Induction bottom plate 9
When it pivots as described above, both movable wing pieces 5 are laterally tilted outward by the tip portion 10, so that the prize winning device l
The state is changed to a second state in which the ball can easily enter the ball from the lateral direction.

When a batted ball lands on the tilted movable wing 5 in this second state, both movable wing 5 rotate to return to an upright state due to the weight of the batted ball, and the guiding bottom plate 9 also uses the support shaft 8 as a fulcrum. The ball rotates horizontally and enters a first state in which it is difficult for a batted ball to enter the ball.

In the winning device 1 constructed as described above, the notch ll is formed in the upper half of the rear part of the guide frame 7, and the fixing part 1 extends from the right and left sides of the back surface of the mounting board 2 to the notch 11.
form 2. This fastening part 12 has a solid shape, and a screw can be passed through it from the rear end.

A wiring board 13 is attached to the rear of the guide frame 7 described above.

This wiring board 13 is made of an insulating plate material and has an annular shape with an opening 14 through which the guide frame 7 passes, and a wiring part 15 and a magnetically sensitive switch 16 are provided on the back surface. And this wiring board 1
3 through the opening 14 from the rear end of the guide frame 7 to the fastening part 1.
2 with screws or the like, a permanent magnet 17 is provided on the induction bottom plate 9 so as to face the magnetically sensitive switch 16 to be fixed.

This permanent magnet 17 is located on the rear lower surface of the guide bottom plate 9, and when the guide bottom plate 9 rotates upward and both movable wing pieces 5 are in the second state, the magnetically sensitive switch 16 is turned on, and the guide bottom plate 9 turns on. is substantially horizontal and both movable wing pieces 5 are in the first state, the magnetically sensitive switch 16 is off.

Therefore, the magnetically sensitive switch 16 is substantially fixed to the guide frame 7, and the permanent magnet 1 is attached to the guide bottom plate 9 and turns on and off the magnetically sensitive switch 16.
7 constitutes a switch mechanism. In the winning device 1 described above, two types of information can be extracted from the magnetically sensitive switch 16.

One is the winning device state detection signal SS that informs the current state of the winning device 1, and the other is whether the state of the winning device l changes from the first state to the second state due to the winning of a batted ball. Irrespective of whether or not the reverse conversion is performed, the winning ball detection signal Sj is used to detect a winning ball when there is a winning ball in the winning device 1.

The winning device state detection signal S is, for example, when the winning device l is the first
As a signal that continuously emits one of the logic levels "H" and "L" when in the state, and continuously emits the other logic level when it is in the second state. Obtainable.

On the other hand, the winning ball detection signal S1 is a logic "H" with the same pulse width both when the winning device 1 converts from the first state to the second state and when converting from the second state to the first state. It can be obtained as a pulse signal, etc. that rises at

Therefore, in the present invention, the winning device state detection signal Ss that is continuously emitted according to the state of the winning device 1 is a light emitting means that lights up or flashes when the winning device 1 is in the second state, as described above. It can be used as information to activate the means to be driven in accordance with the second state of the device. The winning ball detection signal S1 as another signal form obtained from the magnetically sensitive switch 16 starts, for example, another variable winning device or other gaming device (not shown) provided on the surface of the game board. It can be used as a trigger pulse or starting pulse to start the process.

By the way, the magnetically sensitive switch 16 may be sensitive to magnetic force from the outside, and when the winning ball detection signal St is used as a starting pulse to open the big prize opening of the variable winning device, the player must not touch the magnet. Illegal games may be allowed, such as bringing the player close to the winning device l and turning on the magnetically sensitive switch 16, thereby opening the big prize opening of the variable winning device and illegally winning prize balls.

Therefore, in the present invention, when a player approaches a magnet,
In response to this external magnetic force, the above-mentioned winning ball detection signal S,
This is to stop the transmission of the game and make illegal gaming impossible. That is, the winning device l according to the present invention is shown in FIGS. 1 to 4.
According to the illustrated embodiment, in addition to the magnetically sensitive switch 16, a magnetically sensitive element 18, such as a reed switch 18', which is turned on when subjected to an external magnetic action, is provided on the wiring board 13.
and an abnormality detection resistor 19 are provided. This reed switch 18' is not sensitive to the magnetic force of the permanent magnet 17 and is normally turned off, but when a magnet is approached from the outside, it is turned on in response to this magnetic force. And reed switch 18'
The output from the reed switch 18' is processed by the illegal game prevention circuit, and incorrect wiring or disconnection of the reed switch 18' is detected by the abnormality detection resistor 19 and notified by a 1g alarm or a lamp 20 provided on the wiring board 13. do. Incidentally, the lamp 20 faces a lamp hole 2' formed in the mounting board 2.

The optical switch 23 described above is made up of a light-emitting element 24 and a light-receiving element 25, which are disposed on the left and right sides of the guiding frame 7, and when the winning device l is in the first state, the guiding bottom plate 9 is horizontal, so the blocking part 22 is located above the optical switch 23, and the light from the light emitting element 24 irradiates the light receiving element 25, causing the optical switch 2
3 is the off state. However, when the winning device 1 changes to the second state and the guiding bottom plate 9 pivots upward, and the blocking part 22 blocks the light from the light emitting element 24, the light receiving element 25 turns on.

Therefore, when the optical switch 23 described above is converted into the magnetically sensitive switch 16 shown in FIGS. 1 to 5,
Similarly to the magnetically sensitive switch 16, the optical switch 23 can also obtain winning information on the ball that enters the winning device 1.
