Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball counter that counts pachinko balls that have passed through a chuck or the like of a game pachinko machine, and more particularly to a pachinko ball counter effective for preventing counting errors caused by chattering.

[0002]

2. Description of the Related Art Conventionally, as a pachinko ball detection sensor provided in a pachinko ball counter, a non-contact type magnetic sensor utilizing the magnetism or electromagnetic induction of the pachinko ball itself, and a contact type sensor using a micro switch are known. Have been.

[0003]

By the way, due to the nature of the pachinko game, the pachinko ball counter is required to have specifications such as not to make a counting error and not having sensitivity to external magnetism. However, in the case of the non-contact type magnetic sensor, there is a problem that the number of parts and the number of assembling steps increase because a magnetic shield for eliminating the influence of an externally applied magnetic field is required. Especially,
In the case of an electromagnetic induction type sensor using electromagnetic induction, there is a problem that a transmission circuit or the like is required, and this contributes to an increase in cost.

On the other hand, in the case of a contact type sensor using the micro switch, as shown in FIG. 5, when a pachinko ball entering a chucker (not shown) passes through a passage hole 2 formed in a counter body 1, Since the pachinko ball hits the wall surface 3 of the passage hole 2 and rebounds, chattering occurs such that the pachinko ball repeatedly contacts / does not contact the microswitch 4 fixed to the lower portion of the passage hole 2. Is required, which causes a problem that the number of parts and the number of assembling steps increase.

[0005] In addition, the installation environment of the pachinko machine has a lot of dust, and there is a problem that the dust may enter the pachinko machine and the microswitch 4 may malfunction.

The present invention has been made in view of the above circumstances, and a pachinko ball which can effectively prevent counting errors due to chattering by incorporating a simple electronic circuit into a contact-type sensor which is insensitive to magnetism. The purpose is to provide a counter.

[0007]

A pachinko ball counter according to the present invention is a pachinko ball counter for counting the number of pachinko balls that have passed through a chucker or the like of a game pachinko machine, and a pachinko ball passing hole is formed in a vertical direction. And a first sensor provided above the passage hole and detecting a pachinko ball that has fallen into the passage hole, and a first sensor provided below the passage hole and passing through the first sensor. A second sensor for detecting a pachinko ball, and holding a detection signal output from the first sensor until a detection signal is output from the second sensor; and a detection signal from the second sensor. An electronic circuit for performing counting only when is output is provided.

In the pachinko ball counter of the present invention,
The pachinko ball that has entered the chucker is guided by a passage hole formed in the counter body, and first contacts the first sensor. At this time, the first sensor outputs a detection signal indicating that the pachinko ball has dropped into the passage hole.

Thereafter, even if the pachinko ball passing through the passage hole hits the wall surface of the passage hole and rebounds, and the detection signal is repeatedly output from the first sensor, the pachinko ball is detected by the second sensor. The output state is maintained until the first sensor detects the pachinko ball first.

The pachinko ball that has passed through the first sensor is:
Until the detection by the second sensor, the state is not detected by either sensor, but the output state is the first state.
Is kept in the state where the pachinko ball was first detected. Then, when the pachinko balls are detected by the second sensor, counting of the pachinko balls is performed.

Further, the first and second sensors are each provided with a flexible electric contact which is made conductive by contact with the pachinko ball. By utilizing the conductivity of the pachinko ball, the passage of the pachinko ball can be detected by contact with the pachinko ball, and the electronic circuit is simplified.

Furthermore, even when dust enters the pachinko machine, the flexible electrical contact bent when passing the pachinko ball vibrates when returning elastically after passing the pachinko ball, so that the attached dust is removed. As a result, malfunctions due to poor contact are eliminated.

Further, since the electronic circuit is constituted by a flip-flop circuit, a simpler circuit structure can be obtained.

[0014]

An embodiment of the present invention will be described below with reference to the drawings. 1 is a plan view showing an example of the embodiment of the present invention, FIG. 2 is a side view in which a part of FIG. 1 is cut off, FIG. 3 is an electronic circuit diagram, and FIG. In these figures, reference numeral P denotes a pachinko ball, reference numerals 11a and 11b denote detection brushes, and in these drawings, components having the same configuration as those in FIG. The description will be simplified.

In the box-shaped counter body 1, there are vertically formed through-holes 2 which constitute a guide path for pachinko balls P which have entered a chucker (not shown) or the like. , Detection brushes 11a and 11b are provided.

The passage hole 2 has a height of about 10
In order to reliably guide the pachinko balls P falling into the chucker located at 0 mm to the detection brushes 11a and 11b, the pachinko balls P are formed to have a slightly larger diameter than the outer diameter (about 11 mm) of the pachinko balls. I have.

The detection brushes 11a and 11b are both installed so as to protrude inward in the radial direction of the passage hole 2, and after the pachinko ball P has passed through one detection brush 11a, the other detection brush. The through holes 2 are disposed at intervals from each other in the longitudinal direction of the through holes 2 so as to be in contact with the through holes 11b.

The detection brushes 11a and 11b constitute a contact point of an electronic circuit (see FIG. 3) which will be described later, which is turned on / off by contact with the pachinko ball P, so that it has conductivity and the pachinko ball P Is made of a material having flexibility so as not to impede the passage, for example, a thin sheet of phosphor copper, a brush made of conductive plastic fine wire, or carbon fiber.

As described above, the detection brushes 11a, 11b
Is constituted by flexible electric contacts, so that the passage of the pachinko ball P can be detected without contact with the pachinko ball P by utilizing the conductivity of the pachinko ball P itself without hindering the passage of the pachinko ball P. The electronic circuit can be simplified.

Further, even if dust enters the pachinko machine, the detection brushes 11a and 11b bent when passing the pachinko ball P vibrate when returning elastically after passing the pachinko ball P. It is eliminated and the malfunction due to the poor contact is eliminated.

These detection brushes 11a and 11b include:
For example, a flip-flop circuit as shown in FIG. 3 is connected. In the figure, reference numerals 21a and 21b represent A
A NAND gate for adding a NOT circuit to the output of the ND circuit to perform a negation of AND, S1, S2, R1, and R2 are inputs, Q is an output, and V is a power supply.

Table 1 shows a truth table for the electronic circuit of FIG. Hereinafter, with reference to Table 1, FIG. 3 and FIG.
A change in the output Q when the pachinko ball P passes through the passage hole 2 will be described. In Table 1, input values irrelevant to the output Q are omitted (-).

[0023]

[Table 1]

In Table 1, state 1 (hereinafter referred to as "set state") indicates a state in which the pachinko ball P has come into contact with the detection brush 11a as shown in FIG. In this state, the detection brush 11a becomes conductive and grounded (see FIG. 3), and the input of the NAND gate 21a becomes S1 = 0, so that the output becomes Q = 1.

The state 2 (hereinafter, referred to as a "hold state") is, as shown in FIG.
Before the pachinko ball P passes through and comes into contact with the detection brush 11b. In this state, S1 = R1 =
1, R2 = Q '(output state in state 1) = 1 to N
Since the input of the AND gate 21b becomes S2 = 0, Q =
It is kept as 1.

Thus, in the electronic circuit, S
When 1 = R1 = 1, the previous output Q is held as it is. Therefore, as shown in FIG. 4D, in the state after the pachinko ball P has passed through the detection brush 11b, the output Q in FIG. 4C, which is the state before that, is held.

The state 3 (hereinafter, referred to as a "reset state") is, as shown in FIG.
After the pachinko ball P has passed through, and has come into contact with the detection brush 11b. In this state, R1 = 0 to S2 = 1, and S1 = 1, so that the output becomes Q = 0. As described above, the electronic circuit is configured to obtain the output Q = 0 only when S1 = S2 = 1.

Therefore, after the state 1, if the pachinko ball P hits the wall surface 3 of the through hole 2 and rebounds upward and separates from the detection brush 11a, the state is the hold state, and the output is maintained at Q = 1. When the bouncing pachinko ball P falls and comes into contact with the detection brush 11a again, the set state is established, and the output remains unchanged at Q = 1.

Therefore, after the state 1, the pachinko ball P hits the wall surface 3 of the through hole 2 and is bounced many times, and the conduction state of the detection brush 11a is repeatedly turned ON / OFF irregularly. Also, since the output state (Q = 1) when the pachinko ball P first comes into contact with the detection brush 11a continues to be maintained, a counting error that is counted every time the pachinko ball P comes into contact with the detection brush 11a occurs. Never.

As described above, the output Q = 0 (reset state) is obtained only when the input of S1 = S2 = 1 is given by using the flip-flop circuit. Only when the output changes to the state of Q = 0, the passage of the pachinko ball P can be detected and counted, and a counting mistake due to chattering of the pachinko ball P can be effectively prevented, and the electronic circuit can be used. The cost can be reduced due to the simplification.

[0031]

As is clear from the above description, according to the present invention, the following effects can be obtained. (A) The pachinko ball detection signal output from the first sensor is held until the detection signal is output from the second sensor, and is counted only when the detection signal is output from the second sensor. Is provided, the pachinko ball hits the wall surface of the through-hole and is rebounded many times, and even if the detection signal from the first sensor is repeatedly output, the pachinko ball is kept in the first position. Continue to hold the output state when first detected by the sensor of
It is possible to eliminate a counting error such as counting every time the first sensor detects.

(B) Since the first and second sensors are each provided with a flexible electric contact,
Using the pachinko balls' own conductivity, the passage of pachinko balls can be detected by contact with the pachinko balls without hindering the passage of the pachinko balls, thereby simplifying the electronic circuit and reducing costs. it can.

Further, even if dust enters the pachinko machine, the flexible electrical contact bent when passing the pachinko ball vibrates when it returns elastically after passing the pachinko ball.
Adhered dust is removed, and operation failure due to poor contact can be eliminated.

(C) Further, since the electronic circuit is constituted by a flip-flop circuit, the electronic circuit can be made simpler and the cost can be reduced.
