Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pachinko machine in which a ball sent to a shooting position is bounced off by a spring rod and guided to the surface of a game board via a guide rail, in which the ball is sent to the shooting position one by one. The present invention relates to a ball supply device, and particularly relates to a ball supply device that is effective for a ball feed device in which a firing rod is driven by a periodic signal.

The present applicant has disclosed a rotary solenoid type firing device that drives a bullet rod using periodic signals, and other intermittent drive sources, which eliminate the deficiencies of conventional hit ball supply devices using motors and cam drive systems. has been done. However, even as a device for sending individual batted balls to the above-mentioned firing device, as in the past, a cam piece is actuated by a rod connected to a spring rod, and one end of the cam piece tilts the feeding rod to supply the batted ball. It has a structure that allows However, such a structure is complex and prone to failures, requires highly accurate position adjustment of component parts, and is also troublesome and expensive to manufacture, so it is better to have something as simple as possible.

The present invention has been proposed in view of the above, and includes a first intermittent drive source that operates intermittently based on a periodic first signal to drive a firing rod that bounces a ball at a firing position, and a first intermittent drive source that fires a ball at a firing position. A second intermittent drive source that operates in response to a periodic second signal is connected to a ball receiver that is driven to supply the ball to the ball, and the first signal and the second signal are electrically timed by a control means. In addition, by controlling the bounce of the ball by the ball-pulling rod and the supply of the ball by the ball receiver, the structure is simplified, streamlined, and improved in reliability.

The present invention will be explained below with reference to embodiments of the drawings.

1 and 2 show an embodiment of the present invention, in which the base end 1a of the guide rail 1 is the firing position and the ball is hit once.
The springing rod 2 that shoots the balls placed thereon is driven by a first intermittent drive source 3 such as a rotary solenoid that operates intermittently by receiving a periodic first signal. It is becoming more and more like this.

In this case, the first intermittent drive source 3 is operated at a rate of, for example, 100 pieces/min (as shown by the signal line in the upper part of FIG.
Every time a periodic first signal Pa of about 1.6 Hz is received, the elastic rod 2 is moved from the retracted position (solid line) against the biasing force of the return spring 4 acting on the elastic rod 2. A structure is used in which the ball is rapidly rotated to the firing position (imaginary line) to bounce the ball at the firing position 1a.

Generally, a circuit for operating and controlling the first intermittent drive source 3 has a configuration as shown in FIG.

That is, when a player operates a starting switch 5 provided at an appropriate position on the pachinko machine to the starting mode (in this case, the switch contact is closed), the oscillator 6 shown as a control means is activated, and the oscillator 6 operates at a rate of, for example, 100 oscillators per minute. A first signal Pa is generated. This first signal Pa (see also FIG. 3) is amplified to a power dimension by a power amplifier 7 as a control means, and is applied to a first intermittent drive source 3 such as a rotary solenoid.

The oscillation frequency of the oscillator 6 can be easily changed using an electric circuit by operating the volume 6a, etc., so if the operation knob 6b of this volume is provided at a position where the player can operate it, the player can: It becomes possible to adjust and select the desired oscillation frequency and, ultimately, the number of bullets per unit time. Further, adjustment of the rebound force related to the flight distance of the batted ball can be performed using a volume 7a connected to adjust the gain of the power amplifier 7.
Therefore, if the operating knob 7b is also placed facing the player, the player can freely adjust the force of the ball hit by the ball hitting rod 2. It is conceivable that the start switch may be operated by grasping it together with the knob 7b, or may be closed when the knob 7b is slightly turned. However, the elasticity of the ball hit by the elastic rod 2 is adjusted by mechanically adjusting the tension of the return spring 4 instead of electrically as described above.
This can also be done by adjusting the force that resists the driving force of the first intermittent drive source 3, such as a rotary solenoid.

The configuration of the rotary solenoid shown as an example of the first intermittent drive source 3 is well known and does not need to be explained in detail, but as described above, the resilient rod 2 is periodically driven by the periodic first signal. As other first intermittent drive sources, one using a simple solenoid or one using a pulse motor can also be used.

On the other hand, the batted ball supply device of this embodiment uses a second intermittent drive source whose drive source is driven by a second signal synchronized with the first signal of the first intermittent drive source (however, the polarity is opposite). do. In the embodiment shown in FIGS. 1 and 2, the batted ball supply device driven by the second intermittent drive source 10 has a configuration substantially similar to that which relies on a known mechanical drive.

That is, the ball tray 11 into which the player holds the balls has a flow path 12 through which the balls inside flow down toward the base end 1a of the guide rail, and the tip of this flow path 12 is driven so as to supply the balls one by one. The ball receiving portion 13 faces the ball receiving portion 13.

The ball receiving part 13 and the guide rail base end 1a are located approximately in parallel, but since there is a blocking piece 14 between them, the ball receiving part 13 is lowered and communicates with the tip of the flow path 12. In this state, the ball resting on the ball receiving portion 13 cannot move to the base end 1a of the guide rail, so it remains stationary.

However, when the ball receiving part 13 rises, the balls placed thereon can pass over the blocking piece 14, roll out from the supply port 15 opened on the side thereof, and fall onto the base end 1a of the guide rail.

In this case, the ball receiver 13 is raised and lowered by an operating rod 1 having the ball receiver 13 at one end and pivotally connected to a pin 16 at the other end.
This is done by vertical movement of 7. A restoring means 18, such as a restoring spring, is generally connected to this operating rod 17, and the ball receiver 13 is normally kept in a lowered state.

Then, the plunger 10a of the solenoid shown as the second intermittent drive source 10 is connected to the operating rod 17, and when the solenoid is energized, the plunger 10a
The operating rod 17 is pulled down through the above operation, and the ball receiving portion 13 is raised to the supply port 15, and the balls on the upper surface are transferred to the firing position on the base end 1a of the guide rail.

On the other hand, considering the timing of supplying the ball to the firing position by the ball receiver 13 and firing the ball at the firing position by the firing rod 2, first, the second intermittent drive source 10 is activated once, One ball is sent to the firing position, and then the bullet rod 2 is driven once by the first intermittent drive source 3, during which time the second intermittent drive source 10 is restored and fires the next ball on the ball receiver 13. The timing is such that the first intermittent drive source 3 is activated again when the firing rod 2 returns to its original position after the firing is completed. Considering this point and also considering that the first intermittent drive source 3 is intermittently operated by the first signal Pa shown in FIG. 3 as described above, at least this first signal
It is sufficient to generate a second signal Pb between Pa and Pa and operate the second intermittent drive source 10 using this second signal.In the end, as shown in Fig. 3, basically the first signal The second intermittent drive source 10 may be actuated by a second signal having the same phase as the frequency of Pa, particularly a second signal Pb having a phase difference of 180 degrees (opposite phase).

On the other hand, in the oscillator 6 which is emitting the first signal Pa,
This can be configured very simply and rationally by using something with an inverted output. That is, the inverted output I
It is sufficient to simply apply the second signal to the second intermittent drive source 10 after passing through the power amplifier 19 as appropriate, and the intermittent relationship between the firing timing of the batted ball and the supply of the ball to the firing position will naturally be controlled. You can get the action. However, one first signal Pa causes the first intermittent drive source 3 to
is activated once, and at the same time as the first signal falls, the second intermittent drive source 10 is activated by the second signal Pb, the ball transfer timing may not match due to a delay in the mechanical system. In that case, for example, a lead angle circuit may be used for the second signal Pb to provide control so as to provide a time lag between the falling and rising edges of both signals Pa and Pb.

Another embodiment of the present invention will be described with reference to FIG.
The ball bearing part 13 is directly supported by the ball bearing part 13. In this embodiment, the position of the ball supply port 15 and the direction of the blocking piece 14 are different from those of the above-described embodiment, and the ball pushed up by the ball receiving part 13 passes forward over the blocking piece 14 and is fed. It falls into the mouth 15 and exits laterally.

In another embodiment shown in FIG. 6, a pulse motor (step motor) is used as the second drive source 10 instead of a solenoid. This pulse motor is an embodiment in which the pulse motor rotates the rotary shaft 10b by a predetermined angle every time it receives one second signal Pb in the embodiment described above.

In this case, the pulse motor M serving as the second intermittent drive source 10 rotates 90 degrees every time the second signal is applied, and the rotation shaft 10b has four ball bearing parts 13 facing in one direction with a 90 degree phase. There are several. Now, a description will be given of the state in which one ball receiving portion 13 communicates with the tip of the flow path 12 and has one ball placed thereon. In this state, the ball on the ball receiving part 13 is stopped from flowing down by the blocking piece 14, and the supply port 15 above the blocking piece (not shown, but facing the base end of the guide rail as in the above embodiment) It is located below. Then,
A second signal is sent from the power amplifier 19 at a predetermined timing.
When Pb is sent, motor M rotates 90°,
As the ball holder 13 rotates, it rotates, ejects the ball above it when it passes the batted ball supply port 15, and then rotates further and stops at a 90° rotation position. At that time, the ball receiving part 13 that follows in the rotational direction communicates with the tip of the flow path 12, and waits with the next ball placed thereon. Thereafter, this driving is repeated every time the second signal is sent.

Incidentally, each of the above embodiments has been described on the premise that the firing rod is driven to the firing position when the first intermittent drive source 3 receives the first signal by the control means. However, on the contrary, when the first signal is received, the ball is pulled to the retreat position, and at the fall of the first signal, the ball at the firing position is pulled by the biasing means having a biasing force in the opposite direction to the embodiment shown in the drawings. It may also be one that allows the bullet to be fired. In that case, the phases of the first and second signals Pa and Pb are not alternating as described above, but are in positive phase. That is, the second intermittent drive source is activated by the second signal Pb at the same time as the first signal Pa causes the spring rod 2 to be pulled backward.

In this case, both signals may be derived together from the positive output Q of the oscillator serving as the control means.

In summary, according to the present invention, in a pachinko machine equipped with a first intermittent drive source that operates the bullet rod intermittently based on a periodic first signal, the ball is driven to supply one batted ball to the firing position. A second intermittent drive source that operates in response to a periodic second signal is connected to the ball receiver, and the first signal of the first intermittent drive source that drives the elastic rod and the second signal that drives the ball receiver are connected to the second intermittent drive source that operates in response to a periodic second signal. The second signal of the two-intermittent drive source is electrically timed by the control means to control the firing of the ball by the firing rod and the supply of the ball by the ball receiver, so the configuration of the batted ball supply device is as follows. This greatly simplifies the process and is superior in terms of production and cost.

Moreover, since both signals can be controlled with good timing by the control means, the timing of supplying the ball can be accurately and smoothly. Therefore, uneven flight of the ball can be prevented and the ball can be continuously and repulsed with stable repulsion force.
