Description

Detailed Description of the Invention The present invention provides a pachinko machine in which the receiving state of game balls is changed by rotating a rotary winning device of a variable winning device by electrical action, on the condition that a winning is made to a specific winning opening. It's about machines.

Various pachinko machines have been developed in the past, in which the state of the game balls of the winning device is electrically changed on the condition that a prize is won in a specific winning opening.

However, in conventional pachinko machines, a pair of movable wings are pivoted on a so-called tulip (like a tulip), and the movable wings are made to stand upright or tilt in a roughly V-shape to allow the game to be played. Since the system converts the receiving state of the ball, 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. The game board is equipped with 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. In addition, by electromagnetically controlling the rotation of the rotating winning tool via the control circuit by the specific winning detection output from the specific winning opening, it is possible to diversify the game content and increase the interest of pachinko games more than ever. The purpose of the present invention is to provide a pachinko machine that does the following.

Furthermore, the rotation of the rotating winning tool is electromagnetically controlled via the control circuit by either the output from the winning detector due to the ball entering the rotating winning tool or the specific winning detection output from the specific winning opening. It is something.

An example of the present invention will be described below in detail with reference to the drawings.
In the figures to FIG. 4, l indicates the variable winning device as a whole, which is composed of a rotating winning device and a winning device main body 3.

The rotating prize winning tool 2 has a relatively narrow first socket facing outward at one end with the shaft hole 5 at the center, and also has a relatively narrow first socket facing outward.
And at the other end position on the center line

In this embodiment, the receiving donkey and 6B have a front wall 7, left and right wall holes and holes, and a bottom m9, and when in the upper rotation position, the game ball is received from the receiving opening facing upward, and from the rear opening IO. It is designed to be derived backwards.

The winning device main body 3 has a base plate 13 extending in the vertical direction, and a fixed shaft /II extending forward is installed in the center of the base plate 13. For example, a vertically elongated rectangular positioning piece 15 is fixed to the base of the fixed shaft /l, and a positioning piece almost the same as the outer shape of this positioning piece 15 is placed on the back side of the rotating winning tool 2 facing the positioning piece is. A locking groove 16 having an inner surface shape is formed. The length of the fixed shaft /lI is made longer than the front and back thickness of the rotating winning tool λ, so that when the rotating winning tool 2 slides to the rear position close to the base plate /3, the positioning piece /j is inserted into the locking groove /6. Fit into sockets 6A and 6
It is locked and fixed with B facing up and down. When the rotating winning tool KO 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 ljO, and the rotating winning tool λ freely rotates on the fixed shaft/Hirogami. It has been made possible.

A way)/7 is attached to the eccentric position of the rotating winning tool 2, and when the rotating winning tool 2 changes from a state where its sockets 6A and 6B are facing up and down to a free rotating state, a way)/7 is attached to the eccentric position of the rotating winning tool 2.
7, the rotation can be started in either the left or right rotation direction.

Two permanent magnets/KL and l are placed on the left and right positions symmetrical to the center line
IR is provided. The permanent magnets /IL and llR have mutually different polarities, for example, N and S magnetic poles, respectively, exposed toward the back surface side. These magnetic poles/J'L and l
Two magnetic poles 2/L and 27R of the electromagnet 2O are arranged at a position on the base plate 13 facing tR.

The electromagnet 2O has a U-shaped core 2/, and this core 21 is fixed by a mounting bracket 2j to the lower chamber of a guide gutter plate n attached to the back surface of the base plate 13 that divides the case n into upper and lower parts. A coil 26 is wound around the center of the core 21 and electrically led out of the case n via a cord 27 and a connector 2Ir.

In the base plate 13 part of the upper chamber 29 of the case, the game ball introduction port 3O is connected to the rear opening 1 of the socket U or 6B of the rotating winning device 2.
0, and as a result, the upward socket guides the game balls that have entered 6B through the introduction port 30 to the upper chamber 2 partitioned by the guide gutter plate 23, and the rear part of the upper chamber 29. It is designed to be discharged through an outlet 31 provided at the end.

Note that 32 is a magnetic shielding material.

In terms of implementation, the base plate /3 is fixed to the game board of the pachinko machine,
In this way, the game balls 35 that have flown down the game board are collected into the safe ball recovery gutter provided on the back side of the game board through the upper chamber 29 of the socket or 6B of the full rotation winning tool 2 and the case n.

In addition, the connector 2Ir is connected to a control circuit provided in a part of the back mechanism of the pachinko machine, 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 2B of the electromagnet 2O is reversed by the detection output.

In the above configuration, it is assumed that a unidirectional excitation current is normally applied to the coil of the electromagnet 2O, and the magnetic poles 2/L and 27R are in the S-pole and N-pole states, respectively.

At this time, the rotating prize winning tool 2 has magnetic poles 2 and 2 of the electromagnet 2O.
7R, the permanent magnets /IL and /J'R of opposite polarity are rotated to a position facing the magnetic pole col and J/R, and this attractive force causes the base plate to /3 side, the positioning piece /j fits into the locking groove lB, and thus the first socket, which is narrow and difficult for the game ball to enter, turns upward and flows down, as shown in Fig. 1. The rotating winning tool 2 is locked in a state where it can receive the game balls that come. At this time, it means that the prize winning device l 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 Philco B by the specific winning detection output that detects this gaming ball, the magnetic pole col of the electromagnet 2o and the By reversing the polarity, it matches the polarity of the opposing permanent magnets/IL and ltR. At this time, magnetic poles 2/L and 2/R and magnet /rL
Due to the repulsive force generated between and /IB, the rotating prize winning tool λ slides in the direction away from the base plate 13 and engages the locking groove /6.
The locking of the positioning piece /j is released. Therefore, the rotating prize winning tool 2 becomes in a free rotating state and starts rotating in a certain direction of the weight /7 (counterclockwise in the case of FIG. 1). When the magnets /7L and ltR eventually rotate to a position where they coincide with the introduction port 30, the rotating prize winning tool λ continues to rotate due to inertia. Therefore, the magnets /IL and /ITL begin to generate an attractive force with the magnetic pole 2/B and the col, and continue to rotate until the socket 6B is directed upward.

When the locking groove /6 of the rotary prize winning tool 2 eventually reaches the position where it engages with the positioning piece 1, the rotary winning prize tool 2 is attached to the base plate /3.
The locking groove /6 is positioned 1h.Determining piece 1
It is locked at 5. At this time, it means that the prize winning device 1 has been switched to a state where the winning rate is high in which the second socket 6B, which is wide and can easily receive game balls, is directed upward.

When the game ball enters the specific winning hole again in this state, the direction of the excitation current of the electromagnet 2O is reversed again, and the repulsive force generated at this time releases the locking of the rotating winning tool 2 to the base plate /3, When the rotation starts in the direction of rotation by the weight /7 and as a result, a suction force is generated, the rotary prize winning tool λ is locked to the base plate 13 by this suction force, and it is again moved to the first socket which is 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 rotating winning device 2 rotates every time a game ball enters a specific winning hole, and alternately turns the first winning donkey with a low winning rate or the second winning hole 6B with a high winning rate facing upward. Switch to .

In the above description, an elongated, almost rectangular piece is used as the positioning piece 15, but various other shapes can be applied.In short, even if the rotating winning tool 2 is turned upside down, the locking groove 1
It suffices if it has a symmetrical shape that can fit into 6.

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 2O, 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 of the case n is connected to the upper chamber λ while leaving the front half, and the lever p for ejecting game balls is provided in this rear half II/. The lever p has a cross-sectional shape, and as is particularly clear in FIG. It is freely supported.

When looking at the case 22 from the back (Fig. 7), a winning detector tlS having a microswitch configuration is provided at the rotating position of the lever in the time phase direction, and the lever p is normally operated by the winning detector Q. It is pushed by B and is in a rotating state in the counterclockwise W [direction shown by the solid line.

When the game ball 35 enters the guide gutter plate n from this state, it falls from the guide piece k onto the lever p and rotates it to the clockwise position shown by the dotted line. At this time, the winning detector Q operates and sends a winning detection signal to the control circuit via the code≠7 and further via the connector q. When the lever p rotates clockwise, the game balls 3 that have fallen onto the lever p are discharged to the outside according to the discharge date and time set on the left side of the case n when viewed from the front using this as a guide.

In this way, if a game ball wins via the socket 6B of the rotating winning device, the winning detector (IS) detects this, and based on the detection output, the control circuit controls the coil 2 of the electromagnet 2O. By reversing the direction of the excitation current of B, 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 within the gaming section, and also to change the gaming mode more than before based on the operating conditions of the control circuit set in advance. It is possible to diversify the game and significantly increase the interest of pachinko games.

In addition, since the variable winning device is provided with a winning detector, the rotating winning device can be rotated by the game ball 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, in the above description, a case has been described in which the rotary winning tool λ is configured to have two sockets and 6B, but instead of this, two or more sockets may be sequentially provided at a predetermined angular spacing. In this case, an electromagnet having a plurality of magnetic poles sequentially arranged 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/hiro on the rotating 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.
