Description

[Detailed description of the invention] The present invention relates to a variable winning device for a pachinko machine.

Conventionally, this type of variable winning device has two movable wing pieces pivoted to face each other on the surface of a base plate, and by rotating both movable wing pieces, the upper end interval is changed to change the receiving state of game balls. What is called a tulip is often used to convert the .

However, in the above-mentioned variable winning device, the tip of the swinging bottom plate pivoted on the back side of the base plate is engaged between the lower ends of both movable wings, and the swinging of the swinging bottom plate allows the game ball to be received. Since it is a mechanical type that changes the state, the position adjustment between the swinging bottom plate and both movable wing pieces is delicate, and assembly requires skill. In addition, since the conversion operation of the receiving state of game balls is all controlled mechanically, the structure becomes extremely complicated when diversifying the game content by linking with other winning devices. Furthermore, the operation itself when changing the receiving state of the game ball lacks freshness, and the interest of the pachinko game cannot be sufficiently increased.

Therefore, in the present invention, a rotating winning tool having permanent magnets with different magnetic poles is rotatably attached to a fixed shaft of a base plate, and the permanent magnet of the rotating winning tool has magnetic poles of an electromagnet whose polarity can be changed by a control circuit. To provide a variable prize winning device which has a simple structure and is easy to assemble, capable of changing the accepting state of game balls by electromagnetic force and changing the form into a ticket.

By connecting a winning detector that detects the winning balls that have entered the rotating winning device to the above control circuit, the conversion operation of the variable winning device can be electrically controlled even by the game balls that have entered the variable winning device itself. To provide a variable prize winning device which is small in size and has a simple configuration, which can be played reliably and the contents of the game can be set to various types.

An example of the present invention will be described in detail below with reference to the drawings.
First, in FIGS. 1 to 4, reference numeral 1 indicates the variable winning device as a whole, which is composed of a rotating winning device 2 and a winning device main body 3.

The rotating prize winning tool 2 has a relatively narrow first socket 6A facing outward at one end with the shaft hole 5 as the center, and a shaft hole 5 and a center line X passing through the shaft hole 5. At the other end position, a second receptacle 6B which is relatively wide and into which game balls can easily enter is formed facing outward with an angular interval of 180°.

In this embodiment, the sockets 6A and 6B are the front wall 7,
It has left and right walls 8L and 8R and a bottom wall 9, and when in the upper rotation position, game balls are received through an upwardly facing receiving opening and guided rearward through a rear opening 10.

The winning device main body 3 has a base plate 13 extending in the vertical direction, and a fixed shaft 14 extending forward is installed in the center of the base plate 13. At the base of the fixed shaft 14,
For example, a vertically elongated rectangular positioning piece 15
is fixed, and a locking groove 16 having an inner surface shape substantially similar to the outer shape of the positioning piece 15 is formed on the back surface of the rotary winning tool 2 facing the positioning piece 15. The length of the fixed shaft 14 is made longer than the front and back thickness of the rotary winning tool 2, so that when the rotating winning tool 2 slides to the rear position close to the base plate 13, the positioning piece 15 fits into the locking groove 16 and is received. It is locked and fixed with the openings 6A and 6B facing up and down. When the rotating winning tool 2 separates from the base plate 13 and slides to the forward position from this state, the locking groove 16 escapes from the locked state of the positioning piece 15 and the rotating winning tool 2 freely rotates on the fixed shaft 14. It has been made possible.

A weight 17 is attached to the eccentric position of the rotating winning tool 2, and the rotating winning tool 2 is attached to its sockets 6A and 6B.
When the state changes from a state in which it is directed upward or downward to a state in which it freely rotates, it can start rotating in either the left or right direction by means of a weight 17.

Two permanent magnets 18L and 18R are provided at left and right positions symmetrical to the center line X, sandwiching the shaft hole 5 on the back surface of the rotary winning tool 2. The permanent magnets 18L and 18R have mutually different polarities, for example, N and S magnetic poles, respectively, exposed toward the back side. Two magnetic poles 21L and 21R of the electromagnet 20 are arranged at positions on the base plate 13 facing these magnetic poles 18L and 18R.

The electromagnet 20 has a U-shaped core 21, and this core 21 is fixed by a mounting bracket 25 to a lower chamber 24 of a guide gutter plate 23 that divides the case 22 into upper and lower parts, which is attached to the back surface of the base plate 13. . core 21
A coil 26 is wound around the center of the cord 27.
and is electrically led out to the outside of the case 22 via the connector 28.

A game ball introduction port 30 is provided in the base plate 13 portion of the upper chamber 29 of the case 22 so as to communicate with the rear opening 10 of the socket 6A or 6B of the rotary prize winning tool 2, thereby opening the upward socket 6A or 6B. The game balls that have entered are guided through the introduction port 30 to the upper chamber 29 partitioned by the guide gutter plate 23, and the upper chamber 29
It is designed to be discharged through an outlet 31 provided at the rear end. Note that 32 is a magnetic shielding material.

In terms of mounting, the base plate 13 is fixed to the game board of the pachinko machine, and the game ball 35 that has flown down the game board is passed through the socket 6A or 6B of the rotating prize winning device 2 and the upper chamber 29 of the case 22, and is provided on the back side of the game board. The ball is collected in a safe ball collection gutter.

The connector 28 is also connected to a control circuit provided in a part of the back mechanism of the pachinko machine, and is connected to, for example, a winning detector that detects when a game ball enters a specific winning opening provided in the upper center of the game board. The polarity of the excitation current to the coil 26 of the electromagnet 20 is reversed based on the detection output.

In the above configuration, it is assumed that a unidirectional excitation current is normally applied to the coil 26 of the electromagnet 20, and for example, the magnetic poles 21L and 21R are in the S-pole and N-pole states, respectively. At this time, the rotating prize winning tool 2 has permanent magnets 18L and 1 of opposite polarity so that an attractive force is generated between the magnetic poles 21L and 21R of the electromagnet 20.
The positioning piece 15 is rotated to a rotational position such that the magnetic pole 8R is opposed to the magnetic poles 21L and 21R, and is attracted to the base plate 13 side by this attractive force.
is fitted into the locking groove 16, and the first socket 6A, which is narrow and easy for game balls to enter, is turned upward and rotated to a state where it can receive the game balls flowing down. The prize winning tool 2 is locked. At this time, it means that the prize winning device 1 is in a state where the winning rate is low.

In this state, when a game ball enters the special winning hole and the direction of the excitation current to the coil 26 is reversed via the control circuit, the magnetic pole 21 of the electromagnet 20
By reversing the polarities of L and 21R, they match the polarities of the opposing permanent magnets 18L and 18R. At this time, magnetic poles 21L and 21R and magnet 18L
and 18R, the rotating winning tool 2 slides in the direction away from the base plate 13,
The locking of the positioning piece 15 with respect to the locking groove 16 is released. Therefore, the rotating prize winning tool 2 becomes in a freely rotating state, and the weight 17 starts rotating in a certain direction (counterclockwise in the case of FIG. 1). When the magnets 18L and 18R eventually rotate to a position that coincides with the introduction port 30, the rotating winning tool 2 continues to rotate due to inertia. Therefore, the magnets 18L and 18R are connected to the magnetic poles 21R and 21
A suction force is generated between the socket 6B and
Continue rotating until it points upward.

When the locking groove 16 of the rotating winning tool 2 eventually reaches a position where it engages with the positioning piece 15, the rotating winning tool 2
slides in the direction approaching the base plate 13, and the locking groove 1
6 is locked to the positioning piece 15. At this time, the winning device 1 is placed in the second socket 6B which is wide and allows easy entry of game balls.
This means that the winning rate has changed to a state where the winning rate is high.

In this state, when the game ball enters the specific winning hole again, the direction of the excitation current of the electromagnet 20 is reversed again, and the repulsive force generated at this time causes the rotating winning device to
is released from the base plate 13, and the weight 1
7 starts rotating in the rotation direction, and as a result, a suction force is generated, the rotary prize winning tool 2 is locked to the base plate 13 by this suction force, and the first socket 6A is again narrow and difficult for game balls to enter. The winning rate changes to a state where the winning rate is low when the arrow is directed upward.

In this way, the rotary winning device 2 rotates every time a game ball enters a specific winning hole, so that the first socket 6A with a low winning rate or the second socket 6B with a high winning rate faces upward. Switches alternately.

In the above description, an elongated, almost rectangular piece is used as the positioning piece 15, but various other shapes can be applied, and the point is that even if the rotating winning tool 2 is turned upside down, it can fit into the locking groove 16. It is sufficient if it has a symmetrical shape.

In the case of FIGS. 1 to 4, a separately provided specific winning detection output was used as a signal for reversing the rotating winning device 20, but when a game ball enters the rotating winning device 2 itself, a reversing operation is caused. You can also do it like this. That is, as shown in FIGS. 5 to 7, the lower chamber 24 of the case 22 is made to communicate with the upper chamber 29, leaving the front half, and a lever 42 for ejecting game balls is provided in the rear half 41. The lever 42 has an L-shaped cross section, and as is particularly clear in FIG. 7, one end is rotatably connected to a shaft 44 directly below the rear end of a guide piece 43 that extends rearward at approximately the same height as the guide gutter plate 23. It is pivotally supported.

When the case 22 is viewed from the back (FIG. 7), a winning detector 45 configured as a micro switch, for example, is provided at the clockwise rotating position of the lever 42, and the lever 42 is normally connected to the operating piece 46 of the winning detector 45. It is pushed and rotated counterclockwise as shown by the solid line. From this state, the game ball 35 is placed on the guide gutter plate 23.
When the lever enters, it falls from the guide plate 43 onto the lever 42 and rotates it to the clockwise position shown by the dotted line. At this time, the winning detector 45 operates and sends a winning detection signal to the control circuit via the cord 47 and the connector 48. As the lever 42 rotates clockwise, the game ball 35 that has fallen onto the lever 42 is discharged to the outside through a discharge port 49 provided on the left side of the case 22 when viewed from the front using this as a guide.

In this way, if a game ball wins via the socket 6A or 6B of the rotary winning device 2, the winning detector 45 will detect this, and the control circuit will control the coil 26 of the electromagnet 20 based on the detection output. By reversing the direction of the excitation current, the rotating winning tool 2 can be reversed in the same manner as in the above case.

As described above, according to the present invention, permanent magnets are provided in pairs on the rotating prize winning tool, and an electromagnet whose magnetic pole can be reversed is provided on the base plate side to create an attractive force or a repulsive force between the rotary winning tool and the permanent magnet. Since the rotating winning tool is rotated by this magnetic action and the receiving state of the game ball is changed, the structure is extremely simple and can be easily assembled. The operation itself when changing the receiving state of the game ball is novel, and the receiving state of the game ball can be changed extremely easily and reliably by simply controlling the electromagnet. It can be increased even more.

In addition, by connecting a winning detector that detects the winning balls that have entered the rotating winning device to the control circuit, the rotating winning device can be rotated by the game balls that have entered the variable winning device itself, and a specific winning device can be detected. Since there is no particular need for a detection signal from the device, not only can it be used in the same way as a so-called chulip, but the game content can be further diversified.

In addition, in the above description, a case has been described in which the rotary prize winning tool 2 is configured to have two sockets 6A and 6B, but instead of this, two or more sockets may be sequentially provided at a predetermined angular interval, In this case, an electromagnet having a plurality of magnetic poles arranged in sequence corresponding to the sockets may be provided on the base plate 13 side, and these magnetic poles may be sequentially and alternately excited to opposite polarities.
Conversely, several permanent magnets corresponding to the sockets are arranged around the shaft 14 on the side of the rotating prize winning tool, and two permanent magnets are placed as electromagnets.
It is also possible to use a polar one. Furthermore, the rotation of the rotating prize winning tool can be realized by combining the number of permanent magnets and the number of magnetic poles of electromagnets in any number as necessary.
