Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control operating device for a triggering device of a pachinko machine, and in particular, to a device capable of digitally (stepwise) selecting the strength of the triggering force.

In recent years, the motor and cam mechanism used in conventional electric trigger devices have been eliminated, and rotary solenoids, etc.
A firing device has been developed that uses a pulsed power-driven drive source that allows the number of hits to be easily adjusted.
Therefore, while playing pachinko, it is unavoidable for players to adjust the spring force by holding the dial with their hands in order to adjust the spring force with the conventional motor and cam mechanism, but there is nothing that can be done with pulsed electric power. There is no reason why such measures that cause hand fatigue should be taken even for the drive type.

Therefore, the present invention provides a group of switches that can select the spring force in several stages, and the player simply operates the switch with his or her finger (by lightly pressing or touching it) that allows the player to select the desired spring force. The main purpose of this work is to improve the quality of the products.

As a result, the player can enjoy playing the game for a long time without feeling fatigued by using simple operations.

Before describing a preferred embodiment of the present invention in detail, FIG. 1 shows a triggering device using a rotary solenoid as an example of a pulse power-driven drive source for a triggering device suitable for the present invention. .

Rotary solenoid 1 shown here
The coil 3 is provided in the middle part of the C-shaped core 2,
A rotor 5 that rotates around a rotating shaft 4 is disposed between the magnetic legs 2a and 2b that generate a magnetic field by supplying power to the coil, and by supplying power to the coil,
The rotor rotates to a position where magnetic resistance is minimized, that is, to a position aligned with both magnetic legs 2a and 2b.

A springing rod 6 is dynamically and integrally fixed to the rotor 5 and the rotating shaft 4, and the springing rod 6 is normally placed in the retracted position shown by the solid line in the figure by a restoring spring 7, whereby the rotor 5 The magnetic legs 2a and 2b are also tilted in a misaligned manner.

When pulsed power is supplied to the coil 3, the rotor 5 rotates as described above, and the firing rod 6 is suddenly rotated to the firing position shown by the imaginary line in the figure.
The ball on the base end of the guide rail 8, which is the firing position, is fired. When one pulse power falls, the restoring spring 7 returns to the above-mentioned initial state, and henceforth, continuous automatic balling can be performed by continuously supplying pulse power.

In addition, in a pachinko machine that circulates balls enclosed within the machine, such as a pachinko machine commonly known as a ball tray 9 into which a player holds balls, or an arrangement ball, a new ball is sent from the standby section through a ball flow path 10 for each ball. a ball feeding device 11 that feeds a ball to a firing position on the guide rail 8;
As shown in the figure, any known type can be used, such as a known type connected to the triggering rod by a linkage or cam mechanism.

In addition, the firing rod 6 is always connected to a tension spring (not shown).
Contrary to the above, the rotary solenoid 1 forcibly pulls the firing rod 6 to the retreat position when it receives pulsed power, and at the fall of the pulse, the tension spring is attached. Some are configured so that the firing rod is returned to the firing position by the force, and the ball is fired at this time.

However, in either case, the basic circuit is as shown in the second diagram.

When the start switch 12 is operated by the player, the pulse oscillator 13 as a pulse generating means is driven and sends a pulse output of a predetermined frequency to the pulse power supply circuit 14 as a power supply means.
The pulse power supply circuit 14 amplifies the pulse power to a sufficient level and supplies the power to the rotary solenoid 1 and its coil 3 to perform the above-mentioned spring action.

Therefore, it is easy to adjust the output power by exerting an electrical effect on this power supply circuit or the power amplifying section, so by adjusting the output power,
The force that rotates the rotor of a rotary solenoid,
In turn, it becomes possible to adjust the elastic force. Furthermore, since it is easy to change the frequency by applying an electrical effect to the pulse oscillator 13, it is thereby possible to adjust the number of oscillation pulses per unit time and, by extension, the number of shots per unit time.

In the present invention, this adjustment is performed by a group of digital switches, and a preferred embodiment is constructed as shown in Figures 3 to 6 using touch switches that require no operating force and can be simply touched with a finger.

First, as shown in the third figure, an operating section 17 having a group of touch switches serving as a plurality of switching means is provided on the front frame 16 or the like of the pachinko machine 15. In the case of this embodiment, a group of touch switches 19 (in the case of illustration, the left side A set of eight touch switches 19a to 19h) is provided, and a group of bullet number selection touch switches 20 (in this case, each switch has a predetermined number of bullets per minute) , 20a to 20d).

Each touch switch has a conductive surface part for making electrical contact with a person or a finger in order to be operated by human stray capacitance or resistance, as in a normal touch circuit, and is connected via lines 21 and 22 as described below. It is connected to a touch circuit (Figure 4).

In addition, each bullet number selection touch switch 20a to 20
In the vicinity of b, lamp means 23a to 23b such as light emitting diodes and incandescent bulbs are arranged as display means for indicating that the selection has been made.

FIG. 5 shows an example of a control circuit for associating the switch group with the drive circuit shown in FIG. 2 above.

In this circuit, a starting switch for the pulse oscillator 13 is not separately provided, but this is because the elastic force selection touch switch 19 also serves as this, and vice versa. 19a to 19h, when the player is not touching the table with his or her finger, that is, when the player is not on the table or is temporarily absent from playing, the pulse oscillator does not operate, and therefore the pulse oscillator does not operate as described above. The rotary solenoid 1 via the pulse power supply circuit 14 will not be driven.

The configuration for this purpose is to calculate the OR of all the outputs of the touch circuits 24, 24a to 24h, which are attached to each of the elastic force selection touch switches 19a to 19h, and which produce an output only when a finger is touching the touch switch. A connection is made to the input switch section of the pulse oscillator through the OR circuit 25, and the OR circuit 2
5, the pulse oscillator 13 may be activated. This configuration is extremely easy for a person familiar with this type of circuit.

In this way, when you touch one of the spring force selection touch switches 19 with your finger, the pulse oscillator 13 operates and the power amplifier 14 converts this output pulse into a power dimension. The output of the touch circuits 24a to 24h related to each elastic force selection touch switch is connected to a D/A so that the output of the touch circuits 24a to 24h for each elastic force selection touch switch becomes electric power for obtaining an elastic force corresponding to the switch being touched.
It is converted into analog information with a different amount of electricity for each switch via the D/A conversion circuit 26 as a conversion means, and the power amplifier or power supply circuit 14 receives the electricity from the D/A conversion circuit 26 at any time. Increase or decrease output depending on the signal. For example, touch switch 1
If the elastic force is to be strengthened from 9a to 19h, the D/A conversion circuit is configured so that the output changes accordingly, and the power supply circuit 14 also changes the rotary solenoid coil accordingly. 3
The electric power that provides the required elastic force is sent to the Conversely, if the power output of the power supply circuit is controlled by an external signal (D/A
This adjustment can be done purely electronically or by using a servo motor, using various known methods such as adjusting the power gain or adjusting the input voltage from the pulse oscillator 13. A person skilled in the art can also easily configure a semi-mechanical method of varying the volume using, for example.

In this embodiment, when the player touches the spring force selection switch to operate the oscillator 13 and the game is in progress, the above-mentioned OR circuit is activated to display that fact. A part of the output of the 25 is taken out and passed through a suitable driver 27 to light up a display 28 such as a lamp. This indicator may be provided at a portion of the switch housing 18 or the like.

In this embodiment, the oscillation frequency of the pulse oscillator 13 is also varied stepwise by the bullet number selection switch 20. Similarly, each touch switch 20a
The finger contact detection signal from ~20d is detected by each of the touch circuits 29a~29d via the line 21, and is sent via switch means 30a~30d that closes only the line showing the output of a diode or the like. , is sent to the oscillator 13 as a variable signal. The frequency of the oscillator can be varied by individually changing the output resistances 31a to 31d of each touch circuit, such as by adjusting the CR constant related to oscillation, for example, by adjusting the R, or by adjusting the potential. .

However, once the touch switches 20a to 20d for adjusting the oscillation frequency (selecting the number of bullets) are touched by a finger, the touch circuit output remains unchanged until the touch switch is reset by touching another touch switch. It is preferable to have a memory circuit that retains the output even if it is removed. In this way, after the player repeatedly operates (touches) the desired number of bullet selection switches, the player only has to move his/her finger to the desired one of the aforementioned bullet force selection switches. Operation is completely convenient. In this case, in order to show which bullet number selection switch is selected, the display means 23a to 23d, such as lamps, arranged near each switch as described above are connected to each of the touch circuits 29a to 29d.
If the output is displayed, the light may be turned on via an appropriate driver 32 in response to the output. Of course, the display means 23 may be integrated into the surface of each switch 20 like a normal illuminated switch, and furthermore, numbers indicating the number of bullets per minute may be attached to the surface of each switch. You may do so.

Taking further practical considerations into consideration, in a normal pachinko machine, as shown in Figure 6, in the back structure, when there is a shortage of prize balls in the upper tank 33 that stores the prize balls, this is detected and a signal is sent. A ball shortage detector 34 that emits a signal, and an excessive accumulation detector 3 that detects when the player's tray 35 is full of prize balls.
6 is provided, it is preferable to stop the operation of the oscillator 13 via the OR circuit 37 in order to interrupt the game when any of these detectors is activated.

Various modifications of the present invention may be considered, but the number of spring force selection switches and shot number selection switches, that is, the number of adjustment stages, may of course be arbitrary, and the touch switch may be replaced with a normal push button switch, toggle switch, etc. However, the installation position of these operation parts is also arbitrary, and the starting switch of the oscillator 13 may be provided separately with reference to the second diagram. The source 1 may also be other than a rotary solenoid.

In summary, according to the present invention, the elastic force of a pachinko machine can be controlled in multiple stages with a very simple finger operation of selecting a desired elastic force switch from among a plurality of switch units, thereby making it possible to enjoy the game. This not only eliminates the fatigue of the user's fingers, but also eliminates the troublesome rotational operation. Further, according to the present invention, it is possible to provide a highly reliable and rational control operation device with an electrical configuration.
