Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for driving a solenoid device for a prize opening opening/closing mechanism in a pachinko machine.

(Prior art) Pachinko machines are designed to increase the probability of winning and increase the interest of the game by using an accessory operation that keeps the winning hole open for a predetermined period of time when a predetermined condition is satisfied during the game. There is something.

What is important in the action of the accessory in such a pachinko machine is, firstly, that the prize opening reliably opens when predetermined conditions are met, and second, that the prize opening does not close during the accessory action. Thirdly, the winning opening must be reliably closed after a predetermined period of time has elapsed.

(Problems to be Solved by the Invention) By the way, winning devices that perform such role-playing actions generally operate an opening/closing part such as a door plate using the power of a solenoid device to open and close a winning opening. It is equipped with a mouth opening/closing mechanism, and the opening/closing mechanism is operated by causing the opening/closing member to open the prize opening by the plunger suction operation of the solenoid device and continuing the plunger suction operation, or by mechanically locking the opening/closing member. There is.

However, no matter which method is used,
This has caused new problems in trying to satisfy the important first to third requirements in the above-mentioned accessory movements.

In other words, if the former method satisfies this requirement, it is necessary to obtain sufficient power from the solenoid device, and a considerable amount of power must be supplied to the solenoid device, and this must be continued. As a result, it is necessary to use a large solenoid device with a large capacity that does not generate heat, resulting in the problem that the winning device becomes larger. Moreover, the power consumption increases accordingly, which is not preferable from the viewpoint of energy saving. Furthermore, as the supplied power increases, the residual magnetism also becomes more pronounced, which increases the uncertainty in satisfying the third requirement, and there is a concern that troubles may occur due to this.

On the other hand, the latter method does not have the same problems as the former method, but if this method satisfies the first to third requirements above, it requires careful mechanical adjustment and requires the addition of a locking mechanism. This creates a problem in that the structure becomes more complicated and the assembly work becomes extremely complicated.

The present invention aims to solve the problems occurring in these conventional techniques.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention reduces the power supplied to the solenoid after the plunger suction state of the solenoid device is stabilized to the extent that this plunger suction state can be maintained. It is characterized by

In such a configuration, methods for reducing the power supplied to the solenoid include intermittent energization and voltage transformation.

(Operation of the Invention) The method of the present invention constructed as described above has been achieved by focusing on the suction force characteristics of the solenoid device as shown in FIG. In other words, the solenoid device requires the strongest suction force at the beginning of the plunger suction, and then the weaker suction force is required towards the end of the plunger suction. There is a considerable difference in the required suction power. Therefore,
The present invention is designed to excessively reduce surplus power by supplying power commensurate with this characteristic.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a device used in an embodiment of the present invention, in which 1 is an input switch, 2 is an input switch pulse generation circuit, and 3 is a block diagram of a device used in an embodiment of the present invention.
1 is a first timer circuit, 4 is a second timer circuit, 5 is an intermittent ratio determining pulse generation circuit, 6 is an AND circuit, 7 is an OR circuit, 8 is a solenoid drive circuit, and 9 is a solenoid device.

The input switch 1 and the input switch pulse generation circuit 2 are used to detect that a predetermined condition is satisfied during a game and issue a command to start supplying power to the solenoid device 9. The input switch 1 is used in a pachinko machine which, when a predetermined condition is satisfied, variably displays multiple types of identification information, stops this variable display, and changes winning conditions depending on the type of identification information displayed at the time of the stop. In the case of a pachinko machine, when the identification information at the time of stopping is specific, or in the case of a pachinko machine whose winning conditions change depending on the winning of a pachinko ball in a specific winning hole, the winning of a prize in that specific winning hole. When the input switch 1 is turned on, the input switch pulse generating circuit 2 generates a pulse as shown in FIG.

The first timer circuit 3 is for continuously energizing the solenoid of the solenoid device 9, and is configured to receive the output signal of the input switch pulse generation circuit 2. When a pulse is generated from , it is turned on at the same time as the rise of the pulse and outputs a pulse as shown in FIG. This first timer circuit 3
The pulse output time is variable and is set to a time until the plunger suction operation of the solenoid device 9 becomes stable.

The second timer circuit 4, the intermittent ratio determination pulse generation circuit 5, and the AND circuit 6 are used to energize the solenoid of the solenoid device 9 intermittently. The second timer circuit 4 determines the intermittent energization time,
The output signal from the first timer circuit 3 is input, and at the same time as the pulse of the first timer circuit 3 falls, a pulse as shown in FIG. 2 is output. The pulse output time of this second timer circuit 4 is variable. The intermittent ratio determining pulse generating circuit 5 determines the intermittent ratio of intermittent energization, that is, the ratio of the time when the solenoid of the solenoid device 9 is energized and the time when the solenoid is not energized. This outputs the following. This intermittent ratio is made variable by changing the duty ratio of the output signal of this intermittent ratio determining pulse generation circuit 5. The output signal of the second timer circuit 4 and the output signal of the intermittent ratio determination pulse generation circuit 5 are input to the AND circuit 6, and the AND circuit 6 performs an AND operation on both signals to generate the second Pulses for intermittent energization as shown in the figure are output.

The parallel output signals of the first timer circuit 3 and the AND circuit 6 are serially input to the solenoid drive circuit 8 through the OR circuit 7, and the solenoid drive circuit 8 amplifies this input signal to A drive signal as shown in Fig. 2 is output to the solenoid device 9, and the solenoid device 9 is continuously energized by this drive signal at the beginning of the plunger suction operation, and thereafter is energized intermittently. There is.

FIG. 5 is a graph showing the results of a test to see how the degree of heat generation of the solenoid device differs between the conventional energization method and the energization method of the present invention. In addition,
This test was conducted on the winning device of a pachinko machine (Japanese Patent Application No. 65980, 1982) for which the applicant has already applied for a patent.
To show the correspondence between the terms used in the application specification of No. 65980 and the terms used in the present application specification, "opening 20" is a winning opening, "gate 22" is an opening/closing member, and "winning prize" is a winning opening. “Ball device 18” is the winning opening/closing mechanism,
“Solenoid 26” is the solenoid device 9.
Also, in this graph, for example, the display "2-1" indicates the intermittent ratio of intermittent energization; in this case, the energization time is "2" and the non-energization time is "1". That is what it means. According to the results of this test, the intermittent ratio is preferably between "3-1" and "5-1" from the viewpoint of both the stability of the operation of the solenoid device 9 and the degree of heat generation.

FIG. 3 is a time chart showing another embodiment of the present invention, in which the power supplied to the solenoid is reduced by voltage transformation. That is, at the beginning of the plunger suction operation, power is supplied by applying a high voltage to obtain the necessary amount of power, and when the plunger suction state becomes stable, the applied voltage is lowered to reduce the supplied power. It is something.

(Effects of the Invention) As is clear from what has been described above, according to the present invention, the surplus power can be minimized, so the degree of heat generation of the solenoid device can be minimized. As a result, there is no need to use a large and large-capacity solenoid device, which has the effect of making the prize winning device more compact.It is also effective in saving energy, and troubles caused by residual magnetism can be prevented as much as possible. It also has this effect. Additionally, since there is no need to add a mechanism to lock the opening/closing member, mechanical adjustment is easy and the structure is simplified, which has the effect of simplifying assembly work. .
