[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine in which the flying of a hit ball supplied to a hit ball launching portion is made uniform and its strength can be easily adjusted from the front side of the pachinko gaming machine.
[0002]
[Prior art]
Conventionally, some electric pachinko gaming machines use, for example, a rotary solenoid to fire a hit ball. This rotary solenoid needs to adjust the flying strength of the hit ball. The flying strength is adjusted by changing the resistance value of the variable resistor that is electrically connected to the rotary solenoid in the operation unit operated by the player. It is. That is, when the player operates the handle body of the operation unit, the resistance value of the variable resistor is changed and the drive current flowing through the rotary solenoid is controlled, whereby the flying strength is adjusted.
[0003]
By the way, the variable resistor is set so that the range in which the variable resistor can be rotated from the beginning is fixed by the configuration of the operation unit (see FIG. 2), and can be variably adjusted only within the range in which the variable resistor can be moved at the initial fixed position. However, each pachinko gaming machine has some variation in the initial position. For this reason, depending on each pachinko gaming machine, the hitting of the hit ball is not uniform even when the same handle body is operated. Therefore, a variable resistor for adjusting the jump at the initial position of the handle body for making the hitting ball always constant is provided separately so that the resistance value at the initial position is always kept constant so that the hitting strength of the hit ball does not vary. I have to.
[0004]
[Problems to be solved by the invention]
However, the variable resistor and the jump adjusting variable resistor are electrically in close relationship with each other, so that both the pachinko gaming machine and the pachinko hall are operated at the initial position before shipment. It is necessary to adjust the jump strength so that it is uniform for each pachinko machine, but the variable resistor is inside the operation section, that is, the front side of the pachinko machine, and the jump resistor is on the back side of the pachinko machine. In particular, the jump adjustment variable resistor on the back side of the gaming machine could not be easily adjusted from the front side of the gaming machine, so this adjustment work took a lot of labor and time. The workability was poor. Further, since it is necessary to provide a jumping adjustment variable resistor, there is a problem that an extra circuit design is forced, the circuit becomes complicated and unstable, and the manufacturing cost increases. This is due to the fact that the initial position of the variable resistor is currently fixed and cannot be varied.
[0005]
Accordingly, the present invention has been made to solve the above problems, and by making the range of use of the resistance value of the variable resistor variable, it is possible to eliminate a jump adjusting variable resistor at the initial position of the handle body. It is an object of the present invention to provide a pachinko gaming machine capable of speeding up and simplifying the adjustment operation of the hit strength of the hit ball and further reducing the manufacturing cost.
[0006]

[0007]
In this way, since the usage range of the resistance value of the variable resistor can be freely changed, the initial position of the resistance value, that is, the flying strength of the hit ball can be made uniform for each pachinko gaming machine by itself, The conventional variable resistor for jump adjustment becomes unnecessary. As a result, the adjustment work can be speeded up and simplified, and the manufacturing cost can be reduced. In addition, since the adjustment means that can variably adjust the range of use from the outside of the operation unit is provided in the operation unit, it is easy to adjust the flying strength of the hit ball when the pachinko gaming machine is shipped or before operation in the pachinko hall Yes.
[0008]

Then, as shown in FIG. 5, the screw 61 is attached to the screw hole 60 of the protrusion 59 provided on the upper front surface of the handle body 21 by tightening the screw 61 through the screw insertion hole 57. Further, in order to prevent the engagement between the meshing portion 52 and the ratchet 56 from being unnecessarily disengaged, an interposition pin 53a is provided on the back surface side of the flange portion 53, and the engagement is not disengaged on the handle body 21 side. Stopper pieces 21a and 21a projectingly project against the interposition pin 53a and restrict the pivoting operation to the right or left. A coil spring 62 is fitted into the shaft cylinder portion 42, and as shown in FIG. 5, one end 62 a is locked to the hook portion 63 on the front surface of the handle body 21, and the other end 62 b is close to the grip portion 19. A terminal at one end of the touch wiring 69 that outputs the touch input of the handle body 21 to the timing growing circuit 66 (see FIG. 8) by inserting the screw 65 through the mounting projection 64 positioned between the connecting cylinder portions 27 and 27 It is fixed together with the portion 70, and always urges the handle body 21 counterclockwise.
[0017]
The pachinko gaming machine according to the present invention has the above-described configuration, and the usage method will be described next. FIG. 8 is a schematic circuit diagram of the hit ball launch control system. When the player holds the operation handle 18 and touches the handle body 21, the touch input is turned on. Thereafter, the handle body 21 is rotated clockwise in FIG. 5 by a predetermined angle, whereby the operating element 39 is released from the action pin 45 and moved upward, and the micro switch 38 is turned on to be activated. As the handle body 21 rotates, the adjustment shaft 30 rotates by a predetermined angle to vary the resistance value, and the output is changed accordingly.
[0018]
The touch input and the signal from the micro switch 38 are output as a motor drive timing signal via the timing training circuit 66 of the control circuit 71. Thereafter, the output signal is sent to both the AND circuit 67 and the voltage comparison circuit 68. That is, the touch input and the micro switch input are detected by contacting the handle body 21 and further rotating the handle body 21, and when both conditions are satisfied, the timing training circuit 66 is activated and the output is ANDed. Simultaneously with the input to the circuit 67, the output of the voltage comparison circuit 68 is input to the AND circuit 67 by comparing the reference voltage generated by the variable resistor 22 with the voltage generated by the current detection resistor 72 according to the rotation angle of the handle body 21. Then, the rotary solenoid 16 is driven by being outputted from the AND circuit 67 to the driving transistor. In this way, by changing the resistance value of the variable resistor 22, the output signal is increased or decreased, and the hitting strength of the hit ball by the rotary solenoid 16 is adjusted.
[0019]
Therefore, when shipping pachinko machines from the manufacturer, it is necessary to determine the range of use of the resistance value of the variable resistor 22 for each pachinko machine, that is, the resistance value at the initial position so that a proper jump state is ensured. However, for this, a screwdriver is inserted into the insertion port 55 from the front side of the operation handle 18, and the tip of the screw is inserted into the operation groove 54, and the handle body 21 is held and fixed in a clockwise direction or counterclockwise. Turn an appropriate amount around. That is, in a pachinko gaming machine in which the hit strength of the hit ball by the rotary solenoid 16 is weak, the angle setting unit 49 is rotated by a necessary amount in the clockwise direction as shown in FIG. Accordingly, the fitting convex portion 58 of the ratchet 56 slides the meshing portion 52 against the elastic force, stops at a predetermined position, and fixes the angle setting portion 49 again. Further, in a pachinko gaming machine having a high hitting strength, the angle setting unit 49 is rotated counterclockwise as shown in FIG.
[0020]
In this manner, the jumping strength of the hit ball can be freely adjusted from the outside of the operation handle 18, that is, from the front side of the pachinko gaming machine, so that the operation can be easily and easily performed. This also applies to pachinko halls. For example, when the resistance value at the initial position of the variable resistor 22 has become unstable as a result of long-term operation, the angle setting unit 49 is required from the front side of the operation handle 18. It is sufficient to adjust by rotating the amount.
It is to be noted that the adjusting means in the present invention is one embodiment, and it is needless to say that adjusting means having other configurations may be used.
[0021]
