Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prize ball supply operating device in a pachinko machine.

In the invention described in Japanese Patent Publication No. 52-43420, which is one of the conventional examples, the prize ball in the prize ball gutter is moved up and down by a safe ball inserted into the ball hole of the drive rotating wheel. It controls the

However, the outer diameter of the balls used in games varies significantly depending on the period and frequency of use (the outer diameter is likely to become smaller than a predetermined diameter due to wear and tear).

) It is a well-known fact that the outer diameters of the balls used in halls are irregular and that the outer diameter and shape of each ball is different.

Therefore, the method of controlling the prize ball case through a safe ball (the outer diameter of this safe ball is a factor in movement movement) as described above theoretically achieves good movement and simplification of structure. However, in actual use, the operating amount of the control board is not constant due to the unevenness of the ball diameters, so it has the disadvantage that there are many malfunctions of the prize ball case and of various mechanisms that operate related to the case. Ta.

In view of the above-mentioned drawbacks, the object of the present invention is to positively control the control member without causing the safe ball to constantly contact the control member, by using a motor control means which has a mechanically different technical idea from the above-mentioned one. It is an object of the present invention to provide a prize ball supply operating device capable of driving a prize ball cam part with a motor.

Hereinafter, a first example embodying the technical idea of the present invention will be described.
This will be explained with reference to the drawings to FIG.

In the drawing, M is a motor installed in the control room 1,
A rotary wheel 2 is fixed to the motor shaft m, and this rotary wheel 2
The two ball holders shown in the figure, which are formed so that the safe ball B can enter and exit from the front shown in the figure, have recessed portions 3a and 3b spaced equally apart, and next to the portions, this ball holder has a second ball holder having a normally open contact LS2a. Limit switch (also called second switch).

) Second limit switch cam portions 4a and 4b for operating LS2 are recessed so that the switch LS2 can be operated.

However, the contactor 12 of this second limit switch LS2
When the motor M is inserted into the cam portions 4a and 4b, the switch LS2 is opened and the power to the motor M is cut off.

The second limit switch cam portions 4a, 4b
Next, prize ball supply cam parts 5a, 5b are protruded, and above the prize ball supply cam parts 5a, 5b, a brake member 6 in the shape of a lever shown in the figure is used to operate the prize ball supply device S. The braking member 6 is attached to a part of the control chamber 1 so as to be able to swing up and down, and the contact surface 6a formed on the lower left surface in the figure is urged by the prize ball supply cam parts 5a and 5b, Since the interlocking rod 7 articulated to the right end of the braking member 6 in the figure is interlocked with the prize ball supply device S in the upper part of the figure, the braking member 6 is swung upward by the prize ball supplying cam parts 5a and 5b. Each time a prize ball (not shown) is supplied from the prize ball supply device S via the interlocking rod 7.

Furthermore, on the left side of the drawing in FIG.
A first limit switch (also referred to as a first switch) having S1a.

), the LSI touch element 11 is inserted into the opening end 8a, so that the switch LLS1 is closed every time the safety ball B is touched by the mouth end 8a.

Next, the electric circuit in this embodiment will be explained with reference to FIG.
Limit switch LS2 is connected in parallel to the motor M power supply circuit.

Next, the functions and effects of the embodiment configured as described above will be specifically explained.

Now, as shown in Fig. 1, the first limit switch LS1
and second limit switch LS2 are both open and motor M
When the rotation of the player is stopped, a ball hit by a player is introduced into the opening end 8a of the guide gutter 8 as a safe ball B (see the imaginary line in FIG. When the switch is closed in response to the weight of ball B, motor M is rotated clockwise as shown in the figure.

At M, the rotary wheel 2 is rotated clockwise in the drawing.

Then, the ball receiver located below the mouth end 8a is rotated to a position where the part 3a faces the mouth end 8a,
When the safe ball B is dropped into the recessed part of the part 3a and the first limit switch LS1 is opened, the contactor 12 of the second limit switch LS2 is already activated by the second limit switch cam. Since the circuit is closed off from the portion 4a, the rotary wheel continues to rotate 20 times.

Therefore, the prize ball supply cam part 5a at the bottom in the figure continues to rotate clockwise, and the contact surface 6 of the upper control member 6
When the control member 6 is swung upward in order to push up the ball a (see Fig. 2), the prize ball supply device is activated via the rod 7, and at the same time a predetermined number of prize balls are supplied to the customer. Ru.

Subsequently, the prize ball supply cam part 5a of the rotary wheel 2 passes slightly beyond the contact surface 6a, and at the same time the contact element 12 of the second limit switch LS2 is recessed into the second limit switch cam part 4b. Said second limit switch LS2
Since the circuit is opened again, the rotary wheel 2 is stopped together with the motor M to enter the standby state shown in FIG. 1, and the above-described operation is repeated every time the safe ball B is introduced.

Next, referring to FIG. 6, we will explain how the ejecting means for the safe ball B is tilted sideways.
a', 3b' are recessed in a shape with a large opening, and the mouth end 8a of the guide gutter 8 is far away from the outer peripheral surface of the rotary wheel 2, and the safe ball B is received in the receiving portions 4a', 4b. ', the structure falls directly from the mouth end 8a, but since the rest of the structure is the same as that of the previous embodiment, the explanation thereof will be omitted, and the operation of this side-turning will be explained next. Then, as shown in FIG. 6, when both the first limit switch LS1 and the second limit switch LS2 are open and the rotation of the motor M is stopped, the player's batted ball is detected as a safe ball B at the mouth end of the guide gutter 8a. 8a (see the imaginary line in FIG. 6), the contactor 11 of the first limit switch LS1 is
The weight of this safe ball B reacts and the same switch LS1
When the motor M is rotated clockwise in the drawing at the same time as closing the circuit, the rotary wheel 2 is rotated clockwise in the drawing by the motor M, and the receiving passage located below the mouth end 8a is rotated by the motor M in the clockwise direction in the drawing. Since the portion 3a' is rotated to a position opposite to the mouth end 8a, the safe ball B is dropped from the large recessed portion of the receiving path portion 3a', but at this time, the second limit switch has already been activated. Since the contact element 12 of LS2 has come off the second limit switch cam part 4a and is closed, the rotary wheel 2
continues to rotate.

Therefore, the prize ball supply cam part 5a at the bottom in the figure continues to rotate clockwise, and the contact surface 6 of the upper control member 6
In order to push up the ball, the control member 6 is swung upward, and at the same time the prize ball supply device S is activated via the interlocking rod 7, a predetermined number of prize balls are supplied to the customer. The rotation of the rotary wheel 2 is stopped in the same manner as in the embodiment described above, and the system enters the standby state shown in FIG.

Next, the separate electric circuits will be explained with reference to FIG.
In the figure, LS1 is the above-described first limit switch, which has a normally open contact LS1a, and is self-held by the normally open contact Rya of the relay Ry.

Tb is a normally open contact of the timer T, which is closed for a predetermined amount of time, and this time amount is set to be a time amount that allows the rotary wheel 2 to rotate 1/2 when there are two prize ball supply cam portions.

Therefore, when the electric circuit shown in FIG. 7 is used, the operation of the timer T causes the device shown in FIGS. Even if `` is excluded, the prize ball supply cam parts 5a and 5b can be rotated by 1/2 rotation by the function of the timer T, and moreover, by using the function of the timer T, the mounting position of the first limit switch LS1 can be changed by using the function of the timer T. It is also possible to attach it not to the mouth end 8a of the guide gutter 8 but to any arbitrary position of the guide gutter 8.

That is, the gist of the present invention is the configuration described in the "claims," which provides a prize ball supply cam section in which a control member for operating a prize ball supply device is provided on a rotary wheel. In order to enable operation, and to control the drive of the motor that rotates the above-mentioned rotary wheel with a switch (first limit switch) provided facing the mouth end of the induction gutter, and to operate this switch with a safe bulb, Unlike conventional prize supply devices, the present invention allows the entire device to operate reliably regardless of the size of the safe balls, and furthermore, the prize ball supply cam section is provided exclusively for the control member. The feature is that the accuracy of cam operation is permanently guaranteed.

In particular, in the device of the present invention, unlike the conventional device in which the safe ball is substituted for the cam, the prize ball supply cam section is fixedly fixed in a substantially protruding manner from the outer circumferential surface of the rotating wheel, so the control The relationship between the member and the contact surface can be designed to perform the desired operation, and the set relationship can be maintained over a long period of time.
