Description

[Detailed Description of the Invention] The present invention is such that, on the condition that a game ball enters a specific winning hole, the rotating winning device of the variable winning device is rotated by electromagnetic action to change the receiving state of the game ball. This is about a pachinko machine that has been used for many years.

Various pachinko machines have been developed in which the game ball receiving state of a winning device is electrically changed on the condition that a game ball enters a specific winning opening.

However, conventional pachinko machines have a pair of movable wings facing each other and are pivoted like a so-called chulip, and the movable wings are made to stand upright or tilt in an approximately V-shape to control the game ball. Since the system converts the acceptance state, the conversion mode is poor and the game lacks interest.

Therefore, in the present invention, a rotating winning tool is rotatably provided on a fixed shaft installed on the surface of a base plate having an inlet for introducing game balls, and a pair of permanent magnets with different magnetic poles are attached to the rotating winning tool with the fixed shaft in between. A variable winning device in which an electromagnet faces the permanent magnet of the rotating winning device, and a specific winning opening that generates a specific winning detection output when a game ball enters and sends it to a control circuit are arranged in the gaming section. In addition, the rotation of the rotating winning tool is electromagnetically controlled via the control circuit by the specific winning detection output from the specific winning opening, thereby diversifying the game content.
To provide a pachinko machine that can make pachinko games more interesting than before.

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, the game ball is received from the receiving start facing upward and guided out rearward from the rear opening 10.

The winning device main body 3 has a base plate 13 that extends in the vertical direction, and a fixed shaft 14 that projects 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
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 side 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 across the shaft hole 5 on the back surface of the rotary winning tool 2. The permanent magnets 18L and 18R have different polarities, for example, N and S magnetic poles, respectively, exposed toward the back side. Two magnetic poles 2 of an electromagnet 20 are located on the base plate 13 opposite to these magnetic poles 18L and 18R.
1L and 21R are provided.

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 on the rear side. Note that 32 is a magnetic shielding material.

In terms of mounting, the base plate 13 is fixed inside the game section on the surface of the game board of the pachinko machine, and thus rotates the game ball 35 flowing down inside the game section into the socket 6A or 6 of the winning tool 2.
B. The balls are collected through the upper chamber 29 of the case 22 into a safe ball collecting gutter provided on the back side of the game board.

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 gaming ball enters a specific winning opening provided in the upper center of the gaming section. 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 2/L 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 as shown in FIG. 1, the first socket 6A, which is narrow and difficult for game balls to enter, is now in a state where it can receive game balls flowing downward. The rotating 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 opening and the control circuit reverses the direction of the excitation current to the coil 26 by the specific winning detection output that detects this gaming ball, the magnetic poles 21L and 2 of the electromagnet 20
By reversing the polarity of 1R, it matches the polarity of opposing permanent magnets 18L and 18R. At this time, the magnetic poles 21L and 21R and the magnets 18L and 1
8, the rotating winning tool 2 slides away from the base plate 13 due to the repulsive force generated between the rotating winning tool 2 and the locking groove 1.
6 is released.
Therefore, the rotating prize winning tool 2 is in a free rotating state, and together with the repulsive force, the rotating winning tool 2 is rotated in the direction where the weight 17 is (first
It begins to rotate (counterclockwise in the figure). Even when the magnet 18R eventually rotates 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 2
1L, a suction force is generated between the socket 6
The rotation continues until B is directed upward.

When the locking groove 16 of the rotating winning tool 2 reaches the 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 or when a predetermined time set in advance in the control circuit has elapsed, the direction of the excitation current of the electromagnet 20 is reversed again, and the repulsive force generated at this time causes the ball to rotate. When the winning tool 2 is released from the base plate 13 and begins to rotate in the direction of rotation by the weight 17 together with the repulsive force, and as a result, a suction force is generated, the rotating winning tool 2 is caused by this suction force. The first socket 6A is locked to the base plate 13 and is narrow again, making it 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 based on the game ball entering a specific winning hole or the achievement of a specific condition, and the rotating winning device 2 rotates to enter the first receiving hole 6A with a low winning rate or the second receiving hole with a high winning rate. The state is alternately switched so that the mouth 6B is directed upward.

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. When the game ball 25 enters the guide gutter plate 23 from this state, it falls from the guide piece 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, a permanent magnet is provided in the rotating prize winning tool, and an electromagnet whose magnetic polarity can be reversed is provided on the base plate side to generate an attractive force or a repulsive force between it and the permanent magnet. A variable prize winning device having a variable prize winning device and a specific winning opening which generates a specific prize winning detection output every time a game ball enters and sends it to a control circuit are disposed in the gaming section, and the rotation of the rotating winning device is electromagnetically controlled by the control circuit. As a result, it is possible to complicate the conversion variations of the variable winning device by combining it with specific winning ports freely arranged in the gaming section, and also to make the conversion variations of the variable winning device more complex depending on the operating conditions of the control circuit set in advance. The modes can be made more diverse than before, and the interest in pachinko games can be significantly increased.

Furthermore, if the variable winning device is provided with a winning detector, the rotating winning device can be rotated by the game balls contained in the variable winning device itself, and the game contents can be diversified.

Furthermore, since the receiving state of game balls can be changed extremely easily and reliably just by controlling the electromagnet, the operating conditions of the control circuit can be easily set, and the conversion mode of the variable prize winning device can be freely changed. Can be configured.

In addition, since the rotation of the rotating winning device is electrically controlled by an electromagnet based on a control circuit, the rotating winning device has a permanent attraction to magnets,
Repulsion action is quick and stable. Therefore, it is possible to moderate the rotational movement of the rotating prize-winning tool, thereby ensuring reliable state change and preventing malfunctions.

In addition, in the above, the case where the rotary prize winning device 2 is configured to have two receivers 6A and 6B has been described, but instead of this, two or more receivers 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 prepared on the base plate 13 side, and these magnetic poles may be sequentially and alternately excited to opposite polarities. Conversely, a number of permanent magnets corresponding to the sockets may be arranged around the shaft 14 on the rotating prize winning tool side, and a two-pole electromagnet may be used. 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.
