When a pachinko ball launching mallet is driven to rotate by a cam that interlocks with a motor, it is necessary to drive a mechanism that supplies the pachinko balls in synchronization with the rotation of the cam. Therefore, for example, a magnet is attached to a cam for driving a pachinko ball launching mallet, and by detecting this with a magnetic sensor, a signal is output once per rotation, and in response to this, the pachinko ball is supplied. When a geared motor is used as a motor, or a geared motor is used as a motor, a sensor mechanism is incorporated into the gear mechanism so that a signal is output once per revolution. .

[0003]

However, in the above-mentioned conventional structure, since the magnet and the magnetic sensor are used, there is a problem that it takes time to assemble them, and there is a problem that the cost of parts is further increased. In addition to driving the pachinko ball supply mechanism according to the specifications of various products, for example, drive the display mechanism such as a lamp according to the firing time of the pachinko ball, or the number of shot balls and the motor. In order to change the number of prize balls at the time of winning according to the rotation position of the prize and to pay out a variety of balls, in order to input and output signals at any rotation position, the magnet mounting position, Alternatively, there is a problem that the magnetization pattern has to be changed according to various specifications.

The present invention has been made to solve the above-mentioned problems, does not require a special sensor component such as a magnet or a magnetic sensor, can be manufactured inexpensively and easily, and can rotate a motor arbitrarily. An object is to provide a pachinko ball launching device capable of inputting and outputting a signal at a position.

[0005]

To achieve this object, a pachinko ball launching device of the present invention engages with a motor and a pachinko ball launching mallet by rotating in one direction in conjunction with the motor. A cam that rotationally drives the pachinko ball launching mallet in one direction, a return spring for vigorously returning the pachinko ball launching mallet that is disengaged from the cam in the other direction, and a return spring returned by the return spring. In a pachinko ball launching device having a stopper member for engaging and stopping a pachinko ball launching mallet, the motor is constituted by a stepping motor, and the stepping motor is opposite to the rotation direction at the time of launching the pachinko ball. It is equipped with a control circuit that controls the rotational position of the stepping motor thereafter by using this as the origin and forcibly performing a step-out by rotating it in the direction. Further, the control circuit is configured to input and output a signal to a pachinko ball supply mechanism or the like when the stepping motor is rotated by a predetermined angle in the positive direction with the position stopped by forced out-of-sync as the origin. There is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 are diagrams showing the configuration of a pachinko ball launching device 8 of this embodiment, in which a well-known stepping motor 1 is provided and a motor drive circuit (control circuit) is provided under the motor 1. 10 is integrally attached. The output shaft 1b of the stepping motor 1 has
A crescent-shaped cam 2 is integrally rotatably attached. The pachinko ball launching mallet 3 is attached so as to be rotatable around a support shaft 3b, and an arm 3a engageable with the cam 2 and a mallet part 3c for hitting the pachinko ball 6 are provided.

A return spring 4 wound around the support shaft 3b.
Is constituted by a torsion coil spring, and biases the pachinko ball launching mallet 3 in the direction of the arrow B so that the pachinko ball launching mallet 3 is always provided with two stopper members 5, 5 each having upper and lower arms. It is elastically held at the position where it abuts. The stopper members 5 and 5 are made of, for example, hard rubber covered with leather, and when the stopper members 5 and 5 collide with the pachinko ball launching mallet 3 rotated in the direction of the arrow B, the stopper members 5 and 5 alleviate the impact and
It has the function of holding the pachinko ball launching mallet 3 in a fixed standby position.

When the stepping motor 1 is driven, the cam 2 which rotates integrally with the output shaft 1b thereof rotates in the direction of arrow A. Along with this, when the cam 2 engages with the arm 3a, the pachinko ball launching mallet 3 is rotated about the support shaft 3b in the arrow C direction. Furthermore, the cam 2 rotates in the direction of arrow A,
When the cam 2 is disengaged from the arm 3a, the pachinko ball firing mallet 3
Is quickly rotated in the arrow B direction by the action of the return spring 4 wound around the support shaft 3b, and returns to the original standby position. At this time, the pachinko ball launching mallet 3 collides with the stopper members 5 and 5 and is prevented from further turning, and at the same time, the mallet portion 3c of the pachinko ball launching mallet 3 hits the pachinko ball 6,
The pachinko ball firing 6 causes the pachinko balls 6 to be fired along the rails 7 by the momentum of rotation of the mallet 3.

FIG. 3 is a block diagram showing a control system related to the stepping motor 1 of the pachinko ball launching device 8. The motor drive circuit (control circuit) 10 is turned on when a switch circuit (not shown) is turned on. During that time, a predetermined drive pulse is supplied to the stepping motor 1 to rotate the stepping motor 1 in one direction so that the pachinko balls 6 are continuously fired. At the same time, when the rotational position of the stepping motor 1 reaches a predetermined angular position, the other mechanism drive circuit 11 drives the other mechanism such as the pachinko ball supply mechanism 9 or the display mechanism.
A drive signal is supplied to.

A motor drive circuit (control circuit) 10
Is also connected to the control circuit 12 of the pachinko machine body. For example, when the number of supplied pachinko balls is determined by the drive mode, the number of shots of the pachinko balls is received from the main body control circuit 12, and It provides the main body control circuit 10 with information such as the launch of a pachinko ball at a predetermined timing.

Next, the operation of the pachinko ball launching device 8 will be described with reference to FIG.

During normal pachinko ball firing, the stepping motor 1 drives the pachinko ball firing mallet 3 to rotate in the direction of arrow C, and therefore rotates the cam 2 in the direction of arrow A (forward direction). Here, when the stepping motor 1 is rotated in the opposite direction, the rotation of the pachinko ball launching mallet 3 is restricted by the stopper members 5 and 5. Using this constraint, the stepping motor 1 is stepped out, and this is the origin.

For example, at a proper timing such as when the power is turned on or when the pachinko ball is normally fired, the stepping motor 1 is rotated in the direction opposite to the normal rotation direction of the pachinko ball, that is, in the direction of the arrow D. When the cam is step-driven so as to rotate more than one rotation, the cam 2 hits the arm 3a of the pachinko ball launching mallet 3 no matter which rotation position is stopped before starting, as shown in FIG. 4 (a). , The pachinko ball launching mallet 3 enters a restrained state. At this time, since the stepping motor 1 further tries to rotate the cam 2 in the direction of arrow D, the stepping motor 1 is stepped out and stopped as is well known. The position stopped by this step-out always becomes a constant rotation position, and this is the origin.

Next, as shown in FIG. 4B, the cam 2 is step-driven to rotate in the direction of arrow A, and the cam 2 is advanced by a predetermined number of steps in the rotation. , For example, when a drive signal is output to the pachinko ball supply mechanism 9, the supply solenoid 9 is responsive thereto.
a is driven, and the pachinko balls 6 are supplied onto the rails 7.

Further, as shown in FIG. 4 (c), the cam 2
Is further rotated, and the arm 3a of the pachinko ball launching mallet 3 is rotationally driven in the direction of arrow C, and the rotation is further advanced,
As shown in FIG. 4 (d), the pachinko ball launching mallet 3 is disengaged from the arm 3a. Then, the pachinko ball launching mallet 3 swiftly rotates in the direction of the arrow B in order to return to the original position by the force of the return spring 4, and the pachinko ball 6 colliding with the mallet part 3c is shot along the rail 7 by this momentum. .

While the cam 2 continuously rotates in the direction of arrow A, a signal is repeatedly output to the pachinko ball supply mechanism 9 every time the cam 2 reaches the rotational position shown in FIG. After being supplied, it is fired by a pachinko ball firing mallet 3.

Since the number of steps of the stepping motor 1 required for the cam 2 to make one rotation is known in advance depending on the type of the stepping motor 1 used, at which rotational position (the number of steps) it is driven with respect to the other mechanism. Whether to output a signal or input a signal can be arbitrarily set. As a result, a drive signal can be output to the pachinko ball supply mechanism 9 at a predetermined timing in accordance with the specifications of various products, and for example, a display mechanism such as a lamp can be driven in accordance with the firing timing of the pachinko ball. Or the number of prize balls at the time of winning can be changed depending on the number of balls fired and the rotation position of the motor to make it possible to pay out a variety of balls, and further, the total number of shots of each pachinko machine. Manage
A signal can be output at an arbitrary rotational position, or a signal can be input conversely, for the purpose of, for example, referring to the adjustment of the payout.

Even if the number of pachinko balls supplied is determined by the drive mode, the main body control circuit 1
By receiving the information about the number of shots of the pachinko balls from 2, the motor drive circuit (control circuit) 10 can set the number of rotations (step number) of the stepping motor 1 accordingly, and the predetermined number of shots is reached. At that point, the rotation of the stepping motor 1 can be stopped.

Further, the main body control circuit 12 gives a signal for changing the number of revolutions to the motor drive circuit (control circuit) 10 at a predetermined timing depending on the situation of the winning ball, thereby further enhancing the playability. It is possible. For example, increase the rotation speed of the motor according to the type of prize ball,
The number of shots of the ball is increased to provide more prize balls, or conversely, the number of rotations is decreased to make it difficult to get the prize balls.

The stepping motor 1 used in this embodiment may be, for example, a high torque type (hybrid type) motor that makes one revolution in a predetermined number of steps, or a low torque type motor. It may be a geared motor in which a reduction mechanism is incorporated to obtain a predetermined torque.

[0023]

As is apparent from the above description, according to the pachinko ball launching device of the present invention, no special sensor parts such as a magnet and a magnetic sensor are required, and the pachinko ball launching device can be manufactured inexpensively and easily. It is possible to input and output signals at any rotation position of. In particular, since the sensor mechanism does not have to be provided on the motor itself, the mechanism is simple and easy to assemble, and the cost of parts does not increase. Moreover, since the input / output of signals can be set arbitrarily, there is an effect that it is possible to easily cope with various specifications.
