Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for counting and dispensing balls in an automatic legal tender machine.

Conventionally, there are methods for counting and discharging balls for ball dispensers, such as using a turntable method or a constant square type counter, but in the case of counting and discharging using a turntable, the inertia of the rotating part is large, so there is a large error in counting the delivered balls. Often, sometimes the supplied balls would not fit into the grooves of the turntable, and there was also the risk of the balls being bitten.

In addition, in the case of a sliding constant cell, the prerequisite is that a certain number of balls will be filled within a certain period of time, so when balls do not flow out continuously from the hopper that is the supply source of balls (balls get clogged)
There was also a risk that balls would be delivered when the ball was full, and balls could not be delivered to the renter continuously.

The purpose of the present invention is to have a fast counting speed, continuously supply balls,
The object of the present invention is to provide a counting and discharging device for a pachinko ball rental machine that is error-free.

Note that the output of NAND9 is connected to the reset terminal RD of the counter CU1 via an inverter N0T7.

Next, the mechanism will be explained with reference to FIGS. 2 to 4.

However, the mounting position of the counter in this embodiment is set at a position where the balls supplied from the hopper (not shown) flow vertically from above to below, and the pachinko balls 1 released are placed in the groove 2. Flow can flow from above to below.

A part of the teeth of a sprocket-like disk 3 is rotatably inserted into the gap 2 so as not to hinder the rotation of the disk 3, and when the sprocket-like disk 3 stops, the ejection of the ball 1 is stopped. The disk 3 is grounded.

A cam 4 is integrated with the sprocket-like disc 3 on its lower surface.

In addition, the lower surface including the cam 4 is located at the 2nd corner of the cam 4, as shown by diagonal lines in black and dotted patterns in white, from the cutout position of the cam 4 in Fig. 3.
The color is white, which allows for the reflection of light rays.

An arm 5, which prevents the sprocket-like disk 3 from reversing and over-rotating, is rotatably attached to a shaft 6, and a magnet 7 shown with diagonal lines in FIG. Another opposing magnet 8 is grounded with the polarity shown and repel each other to smooth the movement of the arm 5.Furthermore, a leaf spring 9 is fixed to the arm 5 at the position shown so that the disc 3
The stopper arm 10 is rotatably mounted on a shaft 11 and can be engaged with a cut portion of the cam 4 of the sprocket-like disc 3.

Further, a plunger 13 of a solenoid 12 is attached to the stopper arm 10 via a fulcrum 14 and can swing from side to side, and is biased in the direction of the arrow by the repulsive force of a spring 15.

Light emitting diodes LED and Cds are grounded opposite white and black markings painted on the lower surface of the sprocket-shaped disc 3.

Next, as an example of the operation of this embodiment, the pachinko ball 1 is
The case where it is emitted will be explained.

First, in Fig. 1, Ll is a coil that detects the passage of a coin and has an inductance of about IMH, forms a tank circuit together with a capacitor C1, and generates a sine wave oscillation of about IMHz in a modified Colpitts circuit together with a circuit including a transistor Tr1. ing.

The oscillation output of the circuit is outputted by the emitter resistor R5 of the transistor Trl, and the variable resistor VR1 in the oscillation circuit is used to adjust the amplitude of the oscillation output voltage and the oscillation stop position.

Now, when a 100 yen coin passes through the same coil L1, the inductance of the tank circuit decreases in Q due to high frequency loss.
Since the resonant impedance decreases, the amplitude of the oscillation voltage decreases, and the output voltage across the resistor R5 decreases.

Therefore, the voltage between the base and emitter of the transistor Tr1 becomes lower than the threshold voltage of the transistor Tr2, and the transistor Tr2 becomes conductive and released.
When the capacitor C7 is discharged, it is released from the pull-up voltage by the resistor R9, and the transistor Tr3
is at H level for a certain period of time, and the output of inverter N0TI generates a pulse voltage in the negative direction.

As mentioned above, the negative pulse voltage generated when the coin passes is generated by R
8. It is input to the S side of the FF, inverts the FF, and
Set the Q output of F to H level.

This output passes through a noise killer (low-pass filter) consisting of a resistor R12 and a capacitor C21, and then is transferred to an inverter N0T.
2 and after inversion, NAND3, N
R8 formed by AND4 is input to the FF, and the Q output of the FF is set to H level, and the Q output is set to L level.

The same Q output conducts the transistor Tr4 and attracts the plunger 13 of the ball ejection solenoid 12.
The arm 10 releases the locking of the cam 4, and the sprocket-like disk 3 falls while fitting into the curved part of the same plate 3 due to the weight of the ball 1 in the groove 2, causing the same disk 3 to rotate.

In addition, as shown in Figs. 3 and 4, light emitting diodes (LEDs)
The light rays mainly containing infrared rays are reflected from the black and white reflective parts to interrupt the amount of light that enters the Cds of the light receiving part.

Now, if Cds is located on the white surface in FIG. 1, the resistance value of Cds decreases, and the CC voltage is input to the base of transistor Tr6,
is conductive, so the base potential of the transistor Tr7 becomes GND and the collector potential becomes H level.

When located in the black area, the resistance of Cds increases, the base potential of the transistor Tr6 becomes higher than the threshold voltage, and the collector potential becomes H level. Therefore, the transistor Tr7 becomes conductive and the collector potential becomes Become L level.

As described above, by the rotation of the sprocket-shaped disk 3, intermittent pulses corresponding to the same rotation can be obtained at the collector of the transistor Tr7 (1 in Fig. 5), and the intermittent pulses are counted twice a week later to play pachinko. Control corresponding to the number of balls 1 released, 35, is performed.

In other words, a part of the intermittent pulse signal of the same collector is NAND NA
A part of the signal that is input to ND5 and branched is input to NAND6 via inverter N0T4, and the output is sent to two input terminals of NAND7 through a time constant circuit consisting of resistors R41 and R42 and capacitors C19 and C20. are respectively input to the input signal H−L−)H−
The frequency of the intermittent pulse from the transistor Tr7 is doubled by changing it as follows: H-+L-H→HH-H→...

The frequency-multiplied signal is inverted by the inverter N0T5 and becomes a waveform with a short pulse width (2 in FIG. 5).

The same signal is also inputted to the clock input terminal 〒 of an ordinary IC counter that generates a binary output from the A-D terminal and uses the RD terminal as the reset terminal, and from the A-C terminal as 3 in Fig. 5.
, the two communication signals shown in 4.5 are output, and according to the logic theory, B
By matching the outputs of the and C terminals, NAND
From 8, a waveform shown at 6 in FIG. 5 can be obtained, which waveform represents the digit 6 in decimal system.

In other words, the number 6 obtained from the black and white color scheme means that the sprocket-like disc rotated three times, and the disc 3 has a curved part into which 10 balls 1 can be inserted. , this means that 30 balls 1 were counted and released.

And the same signal is R8 of NAND1 and NAND2
, is input to Re1 in the FF circuit, inverts the FF, and the output of NAND2 becomes H level, and the inverter NAND
The output of 0T3 becomes L level.

Therefore, the output of NAND3 becomes L level,
The conduction of the transistor Tr4 is released, the stopper solenoid loses its suction force, and the stopper arm 10 returns to its original position due to the restoring force of the spring 15.

However, the cam 4 does not become locked, and the cam 4 continues to rotate and is locked at the next cut.

During this time, the remaining five balls that are inserted into and ejected from the curved portion of the sprocket-shaped disc 3 are ejected.

Then, due to the Cds signal obtained at the same time as the locking, the A terminal output of the counter CUI becomes H, and the NAND8
With the H output of the inverter N0T6 due to the L output of the NAND9, the output of the NAND9 becomes L level.

This L level signal is branched, and a part is sent to the four counter CU1.
RD via inverter N0T5 as a reset signal for
It is connected to the terminal and sets the contents of the counter CU1 to zero.

Further, the other branched signal is used as an on/off signal for a solenoid for opening/closing a lever that prevents the continuous flow of inserted coins.

(The following drawings are omitted) Note that the switch SW2 is a manual reset switch.

Next, the effects of the present invention will be explained.

The present invention includes a sprocket-like disc that rotates in accordance with the number of pachinko balls flowing down a groove, and a stopper arm that engages with a cutout formed in a cam that rotates together with the disc to restrict the rotation of the disc. , the engagement between the same stopper arm and the cam.

(4) Unlike conventional devices, the guide pipe can be directly connected to the counting and discharging mechanism, so there is no need for a tank to store the balls, resulting in miniaturization.

(5) If the ball in the guide pipe breaks, the sprocket-like disc will stop automatically and counting will stop, and after the ball in the guide pipe returns to normal, it will be counted again and the remaining balls will be delivered. This has the effect of supplying the specified number of pitches to the renter.
