Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention generates a pulse signal each time a game item such as a pachinko ball or a game metal is rented according to the insertion of money. The present invention relates to a pachinko hall lending device.

(Prior Art) A ball lending machine, which is an example of a pachinko hall lending device of this type, is provided with an interlocking switch that is activated each time a predetermined number of pachinko balls are lent out in accordance with the insertion of coins. ,
A pulse signal is generated for each operation of this interlocking switch, and a management device is provided on the management device side to receive the pulse signal via a signal line to total the sales of ball lending machines. It is structured so that the aggregated results can be used as materials for pachinko hall management.

(Problems to be solved by the invention) However, in the above-mentioned conventional configuration, when the signal line is broken, the pulse signal is not generated and the management device cannot collect the sales of the ball lending machine. There is a drawback that the totaling result will be completely inaccurate. Moreover, there is a risk that employees of pachinko halls will steal the sales of ball lending machines by deliberately breaking the signal line by using the above circumstances, and such fears are especially related to each pachinko game in recent years. There was a tendency that the so-called ball-to-ball lending machine installed between machines was expanded in a situation where it was widely used.

The present invention has been made in view of the above circumstances, and an object thereof is to be able to reliably detect a disconnection of a signal line,
As a result, it is possible to prevent the situation in which the sales totals result is inaccurate due to the disconnection, and it is also possible to prevent the pachinko hall employee from intentionally disconnecting the signal line and acting fraudulently. The present invention is to provide a lending device for pachinko halls that has the effects described above.

[Means for Solving the Problems] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a voltage signal output terminal and a reference potential terminal having a potential level lower than the output potential of the voltage signal output terminal through a pull-down resistor. It is connected to a management device having a connected signal input terminal, and has an interlock switch that is operated each time a game item is rented according to the insertion of money, and the input side terminal of the interlock switch And the output side terminal to the voltage signal output terminal and the signal input terminal of the management device side, respectively, and the first signal line and the second signal line
In the pachinko hall lending device in which a pulse signal generated at each operation of the interlocking switch is applied to the signal input terminal by connecting through the signal line of the bypass resistor connected in parallel with the interlocking switch. An auxiliary pull-down resistor connected between an auxiliary reference potential terminal having the same potential level as the reference potential terminal and an input side terminal of the interlock switch, and between an output side terminal of the interlock switch and the second signal line Voltage dividing resistance interposed between
Disconnection detection means for generating an alarm signal when the potential level of the voltage dividing resistor and the common connection point of the second signal line becomes the potential level of the reference potential terminal or the potential level of the voltage signal output terminal. It is configured to be provided.

(Operation) The operation when the interlocking switch is configured to be a normally open type will be described.

In a state where neither the first signal line nor the second signal line is disconnected, when the interlocking switch is stopped (turned off), a bias resistor and a split are provided between the first signal line and the second signal line. It will be in the state of being connected via a piezoresistor,
Therefore, the potential of the signal input terminal connected to the second signal line becomes a level obtained by dividing the potential difference between the voltage signal output terminal and the reference potential terminal by the bypass resistor, the voltage dividing resistor, and the pull-down resistor.

Further, when the interlocking switch is operated (turned on) in response to the rental of the game product, the first signal line and the second signal line are connected via the interlocking switch and the voltage dividing resistor. The potential of the signal input terminal rises as much as the shared voltage due to the bypass resistance disappears.

Therefore, a pulse signal is given to the signal input terminal via the second signal line every time the interlock switch is operated, and the calculation means calculates the sales of the ball lending machine based on the pulse signal. Calculate

On the other hand, for example, when the first signal line is disconnected, the potential of the common connection point of the voltage dividing resistor and the second signal line is changed to the potential of the reference potential terminal via the pull-down resistor or the auxiliary pull-down resistor. Can be lowered to the level. Then, in such a case, the disconnection detecting means will generate an alarm signal, which allows the occurrence of a disconnection accident to be known. If the second signal line is broken,
The potential of the common connection point is raised to the potential level of the voltage signal output terminal via the voltage dividing resistor, the first signal line, and the like. Then, even in such a case, the disconnection detecting means will generate an alarm signal. Furthermore, the first and second
Even if both signal lines are disconnected, the potential at the common connection point can be lowered to the potential level of the reference potential terminal via the voltage dividing resistor, auxiliary pull-down resistor, etc. Means generate an alarm signal.

At this time, the disconnection detection as described above is performed by the voltage dividing resistor and the second
The detection is ensured because the potential of the common connection point of the signal line is changed to the maximum value or the minimum value.

If the interlock switch is normally closed,
Although the pulse signals have opposite phases, when a disconnection accident occurs in the first and second signal lines, the disconnection detection means issues an alarm signal in the same manner as described above.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a ball lending machine as a lending device showing one out of a plurality of machines, which is configured to discharge a predetermined number of pachinko balls to the outside of the machine every time a 100-yen coin is inserted, for example. . At this time, the first signal line 2 and the second signal line 3 are connected to the pair of terminals 1a and 1b of the ball lending machine 1, and these signal lines 2 and 3 are connected to the ball lending machine 1 respectively. It is connected to the voltage signal output terminal A and the signal input terminal B of the management device 4 for totalizing sales etc., respectively. still,
Although not shown, the management device 4 is also configured to be able to perform balance calculation and stop control for each of a plurality of pachinko game machines.

In the management device 4, reference numeral 5 is a counting circuit which is a calculation means, and this counts a pulse signal So, which will be described later, which is input to the signal input terminal B through the second signal line 3 to count the ball lending machine. The sales amount of 1 is calculated.
The signal input terminal B is connected to a ground terminal which is a reference potential terminal through a pull-down resistor 6. The voltage signal output terminal A outputs a constant DC voltage of, for example, 24V.

Now, the configuration of the ball lending machine 1 will be described below.

That is, 7 is a normally-open relay switch that is an interlocking switch, and is configured to be activated (turned on) every time the ball lending machine 1 is operated, that is, every 100 yen of pachinko balls is discharged out of the machine. Therefore, the number of times it is turned on corresponds to the sales of the ball lending machine. At this time, in the relay switch 7, the input side terminal 7a is connected to the terminal 1b, and the output side terminal 1b is connected to the terminal 1b via the voltage dividing resistor 8.

A bypass resistor 9 is connected in parallel with the relay switch 7, and an auxiliary pull-down resistor 10 is connected between the input side terminal 2a and a ground terminal which is an auxiliary reference potential terminal. As a result of this connection, the pulse signal So indicating the number of times the ball lending machine 1 has been operated is output to the second signal line 7 every time the relay switch 7 is turned on.

Now, 11 is a detection circuit as a disconnection detection means, which is provided so as to detect the potential of the terminal 1b which is a common connection point of the voltage dividing resistor 8 and the second signal line 3, and the level of the detection potential. Is the potential level Ee (zero level) of the ground terminal or the potential level Ev of the voltage signal output terminal A
When (= 24V), the warning signal Sa is output.
At this time, the alarm signal Sa is given to the buzzer 12, which is an alarm device, for example, so that the buzzer 12 sounds.

The detection circuit 11 is set to have a high input impedance. Further, in this case, the ball lending machine 1 is configured to automatically stop when the alarm signal Sa is output from the detection circuit 11. Here, the operation stop state of the ball lending machine 1 refers to a coin insertion prevention state or a pachinko ball release operation stop state.

Next, the operation of the above structure will be described with reference to the second state showing the change state of the potential level of the terminal 1b.

In a state where the first and second signal lines 2 and 3 are not disconnected, when the relay switch 7 is turned off, the signal lines 2 and 3 are connected via the bypass resistor 9 and the voltage dividing resistor 8. Connected to each other, which causes the second
The potential of the signal input terminal B connected to the signal line 3 of
Bypassing the potential level Ev of the voltage signal output terminal A with the bypass resistor 9
Further, the voltage is divided by the voltage dividing resistor 8 and the pull-down resistor 6 to obtain a level Eoff (Ev>Eoff> Ee).

When the relay switch 7 is turned on by the operation of the ball lending machine 1, the signal lines 2 and 3 are connected via the relay switch 7 and the voltage dividing resistor 8.
The potential of the signal input terminal B is increased by the amount of the voltage Eon (Ev> Eon) which is increased by the amount of the shared voltage by the bypass resistor 9.
>Eoff> Ee).

Therefore, the signal input terminal B is supplied with a pulse signal So that rises from the potential Eoff to Eon every time the relay switch 7 is turned on, and the counting circuit 5 uses the pulse signal So to soure the ball lending machine. The sales of 1 are totaled.
And in such a state, the potential level of the signal input terminal B only changes between Eon and Eoff,
It does not fall to the potential level Ee of the ground terminal or rise to the potential level Ev of the voltage signal output terminal A, and therefore the detection circuit 11 does not output the alarm signal Sa.

On the other hand, for example, when the first signal line 2 is disconnected, the potential of the terminal 1b is changed to the second signal line 3 and the pull-down resistor 6, or the voltage dividing resistor 8, the bypass resistor 9 and the auxiliary pull-down resistor. It is pulled down to the potential level Ee of the ground terminal via 10. Then, in this case,
The detection circuit 11 comes to generate an alarm signal Sa, and in response to this, the buzzer 12 is sounded and the ball lending machine 1 is stopped. When the second signal line 3 is disconnected, the potential of the terminal 1b is raised to the potential level Ev of the voltage signal output terminal A via the voltage dividing resistor 8, the first signal line 2 and the like. Then, even in such a case, the detection circuit 11 starts to generate the alarm signal Sa,
As a result, the buzzer 12 sounds and the ball lending machine 1 stops operating. Further, even when both the first and second signal lines 2 and 3 are disconnected, the potential of the terminal 1b is lowered to the potential level Ee of the ground terminal via the voltage dividing resistor 8, the auxiliary pull-down resistor 10 and the like. Like Therefore, also in this case, the alarm signal Sa is generated from the detection circuit 11, the buzzer 12 sounds, and the ball lending machine 1 stops operating.

Therefore, even if a disconnection accident occurs in the signal lines 2 and 3, a situation in which the counting result by the counting circuit 5 becomes inaccurate can be prevented, and the disconnection accident can be swiftly dealt with by sounding the buzzer 12. It is a thing.
Of course, even if the signal lines 6 and 7 are intentionally disconnected,
Since the ball lending machine 1 is stopped and the buzzer 12 sounds, there is no possibility that an employee of a pachinko hall will act illegally as in the past.

Moreover, the disconnection detection by the detection circuit 11 as described above is
The detection is ensured because it is performed based on the potential of the terminal 1b changing to the maximum value or the minimum value.

When the relay switch 7 is normally closed, the pulse signal So has the opposite phase.
When a disconnection accident occurs in the signal lines 2 and 3, the potential of the terminal 1b changes in the same manner as described above, so that the detection circuit 11 generates the alarm signal Sa.

[Advantage of the Invention] According to the present invention, as is apparent from the above description, in the pachinko hall lending device that transmits the pulse signal indicating the sales amount to the management device side via the signal line, It is possible to reliably detect the disconnection, and thus prevent the situation where the sales aggregation result is inaccurate due to the disconnection, and the pachinko hall employee intentionally disconnects the signal line. This has an excellent effect that it is possible to prevent a fraudulent situation, and moreover, it is possible to determine which of the signal lines provided in a pair has a broken state.
