As shown in FIG. 7, the specific output of the microcomputer 10 is input to the interface 13, and the interface 1
The output of No. 3 is input as a control signal to the driver 15 such as the switching transistor 18 and the voltage from the power source 19 is applied to the opening / closing control solenoid 50 via the driver 15 to attract the movable iron core 53 into the solenoid 50.

The opening / closing control solenoid opens the opening / closing piece so that the opening / closing piece is not closed by a shock even when a game ball collides with the opening / closing piece by deforming the elastic body to push the opening / closing piece open. The movable iron core must be strongly attracted in order to maintain the current, and the current value sent to the open / close control solenoid increases, which may cause deformation of the solenoid mounting part or the plastic around the mounting part due to heat generation in a small solenoid. It was

In particular, in recent years, a variable prize winning device is often made of a plastic excellent in design and mass productivity, and in order to eliminate the above-mentioned drawback, the opening / closing control solenoid must be enlarged and a space must be secured. There was a drawback that there was a problem that did not happen.

[0006]

According to the present invention, when a voltage is applied to an opening / closing control solenoid by a control signal, the voltage of the first power source, which is a large voltage, is first applied, and then during the opening time of the variable winning device. , The voltage of the second power supply having a lower potential than the first voltage is applied to maintain the opening of the movable piece.

The first power supply voltage may be periodically overlapped while the second power supply voltage is being applied.

[0008]

[Operation] According to the present invention, when the open / close control solenoid is energized, a high voltage is first applied to strongly attract the movable iron core to operate the movable rod, and thereafter a second power supply voltage having a low potential is applied. Therefore, the current value during solenoid operation can be reduced while maintaining the operating state of the open / close control solenoid.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the control method according to the present invention is shown in FIG.
As shown in (2), the open / close control solenoid 50 is energized by using two types of power supplies having different voltages. In this embodiment, the signal line from the interface 13 is connected via a pulse generator 41 to a first switching transistor 25 for controlling energization of a 30-volt first power supply 61,
Further, the signal line from the interface 13 is connected to a second switching transistor 35 that controls energization of a 12-volt second power source 62, and the collector of the first switching transistor 25 is connected via a first diode 27 to an opening / closing control solenoid. 50, and the collector of the second switching transistor 35 is also the second diode 37.
It is connected to the opening / closing control solenoid 50 via.

Also in this embodiment, the first inverter 21 and the limiting resistor 23 are provided between the pulse generator 41 and the first switching transistor 25 according to the characteristics of the switching transistor and the conditions of the applied voltage, and the like. Interface 13 and second switching transistor 35
The second inverter 31 and the limiting resistor 33 are inserted between and to form a driver.

Therefore, as shown in FIG. 2, the operation of this circuit example is such that when the open signal of the variable winning device is output to the A signal which is the output of the interface 13, the second switching transistor 35 becomes conductive by this open signal. Then, the C signal which is the input to the second diode 37 is boosted to 12 volts, and the voltage of the second power supply 62 is applied to the opening / closing control solenoid 50 via the second diode 37.
The application of the second power supply voltage via the second diode 37 is maintained during the output of the open signal.

Further, in this embodiment, since the open signal from the interface 13 is also input to the pulse generator 41,
The pulse generator 41 outputs a signal of H level for several hundred milliseconds from the rising edge of the open signal, that is, the output of the open signal, and the H level signal causes the first switching transistor 25 to be conductive and the first switching transistor 25. The B signal, which is the output of, is boosted to 30 V, and the voltage of the first power supply 61 is applied to the opening / closing control solenoid 50 via the first diode 27.

Therefore, when a voltage of 30 V is generated in the B signal, the D signal becomes 30 V which is the same as the B signal by the action of the first diode 27 and the second diode 37, and the voltage applied to the opening / closing control solenoid 50 is 30 V. The voltage applied to the opening / closing control solenoid 50 is only the H-level signal output time of the pulse generator 41. Therefore, the voltage applied to the opening / closing control solenoid 50 is several times from the start of the opening signal output. Only 100 milliseconds, the voltage becomes 30 V, and after the output of the H level signal from the pulse generator 41 is stopped, the output of the open signal is completed.
The D signal drops to 12 volts, which is the voltage of the power supply 62, and this second power supply voltage is applied to the opening / closing control solenoid 50.

It should be noted that the voltage of the first power supply 61, 30 V, is the open / close control solenoid 5 in the conventional variable winning apparatus.
It is the same voltage as that applied to 0 through the switching transistor that is a driver. Thus, this embodiment is the same as the conventional one by making the first switching transistor 25 conductive for a short time immediately after the start of the output of the open signal when the open signal is output from the interface 13 under the control of the microcomputer 10. The voltage of the first power supply 61 set to the voltage is applied to the opening control solenoid 50, and the second switching transistor 35 is made conductive by the opening signal from the interface 13 to set the voltage lower than the voltage of the first power supply 61. Second power source 6
The voltage of 2 is applied to the opening / closing control solenoid 50, and the same 30 V as in the conventional case is applied to the opening / closing control solenoid 50 for a short time set by the pulse generator 41.
After that, it is a method of applying the voltage lowered to 12 V to the opening / closing control solenoid 50.

In this embodiment, the voltage of the first power supply 61 is applied to attract the movable iron core 53 in this manner, thereby deforming the elastic body 58 and moving the movable rod 55 to operate the link bar 57. Thus, the opening / closing piece of the attacker is opened via the link mechanism, and after opening the opening / closing piece, the voltage applied to the opening / closing control solenoid 50 is decreased to the voltage of the second power supply 62 to maintain the attracted state of the movable iron core 53. Therefore, the total current value flowing through the opening / closing control solenoid 50 can be made smaller than in the conventional case, and the heat generation of the opening / closing control solenoid 50 can be prevented.

Furthermore, this embodiment is a method of applying a large voltage and a large current for a short time to deform the elastic body 58 to strongly attract the movable iron core 53 only when the opening / closing piece of the attacker is opened. When the piece is continuously opened, it is possible to hold the attracted movable iron core 53 at the attraction position against the force of the elastic body 58 with a relatively small force, so that the opening / closing control solenoid 50 is downsized. You can also

In addition, in the variable winning apparatus, the one which opens the opening / closing piece to the left and right like the tulip to increase the winning probability, the game ball may hit the outside of the opening / closing piece and try to close the opening / closing piece by impact. Therefore, as in the above-described first embodiment, if a large voltage is applied only immediately after the opening signal is output and only the low voltage is maintained after the opening / closing piece is opened, the game ball hits while the variable winning device is opened. There is a risk of closing the opening / closing piece.

Therefore, in order to prevent the opening / closing piece of the variable winning device from being closed by the impact of a game ball or the like during the opening of the variable winning device, a large voltage opening / closing control solenoid 50 at the start of the output of the opening signal. A large voltage may be applied periodically while the open signal is being output.
In the second embodiment, as shown in FIG. 3, the pulse generator 41 of the first embodiment is replaced with an oscillator 43, and an open signal from the interface 13 is input to the reset terminal of the oscillator 43. When a signal is input to the reset terminal, the reset state of the oscillator 43 is released.

If, as the oscillator 43, an H pulse having a pulse width of several hundreds of milliseconds is output in a cycle of 1 hertz to several hertz, for example, as shown in FIG. 4, the output of the open signal is started. In addition to applying the voltage of the first power source 61, the voltage of the first power source 61 can be periodically applied during the output of the open signal, and while reducing the average current value flowing to the opening / closing control solenoid 50, the game ball is The opening / closing piece can be immediately reopened even if it hits the opening / closing piece and is closed by an impact.

The first switching transistor 25 and the second switching transistor 3 as drivers are also provided.
5 is controlled by the logic circuit 4 as shown in FIG.
It is also possible to alternately make the first switching transistor 25 and the second switching transistor 35 conductive while the open signal is being output by using 5, 47, and, as shown in FIG. 6, the interface 13 controlled by the microcomputer 10. It is also possible to directly input an open signal to the first switching transistor 25 and the second switching transistor 35, and to control the application time and application timing of the first power supply voltage by a program.

It should be noted that the first diode 2 inserted between the first switching transistor 25 for controlling the voltage cut-off of the first power supply 61 which has been set to a high voltage and the opening / closing control solenoid 50.
7 may be omitted, and the open / close control solenoid 50
A protection circuit for preventing overvoltage may be inserted as appropriate.

[0022]

According to the present invention, when the opening / closing control of the opening / closing piece of the variable winning device such as a pachinko machine is performed, when the output of the opening signal is started, a large voltage similar to the conventional voltage is applied to the opening / closing control solenoid. Immediately after the start of output, the applied voltage is dropped, the dropped voltage is maintained until the end of the open signal, or the open / close control method is to periodically return the voltage after the drop. When a sufficient voltage and current is applied to the open / close control solenoid to maintain the open / closed piece in the open state, the voltage applied to the open / close control solenoid is reduced to reduce the average current consumption and prevent heat generation of the open / close control solenoid. Further, there is an advantage that the variable winning device can be operated by a small solenoid.
