Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a test device that can easily confirm abnormalities in the money handling section of a vending machine.

(b) Conventional technology As a test device for vending machines, the
There is a technique disclosed in Publication No. 48697. This is equipped with a bend test switch, and is configured to enable the vending machine to operate without inserting money based on the operation of the bend test switch.

(c) Problems to be Solved by the Invention However, according to such prior art, although it is possible to test the bending mechanism, it is not possible to test the money handling section, and it is difficult to detect abnormalities in the money insertion detection section or the money dispensing mechanism. It is impossible to detect.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a test device for a money handling section which performs a test coin dispensing operation when a coin is inserted while the test switch is activated.

(d) Means for Solving the Problems In order to solve the above problems, the test device for the money handling section according to the present invention includes a test switch that prohibits the calculation operation of the input amount by operation, and a test switch that prohibits the calculation operation of the input amount. and test control means for operating the coin dispensing device corresponding to the type of coin inserted when a coin is inserted when the coin dispensing device is operated.

(e) Operation When a coin is inserted while the test switch is in operation, the test control means operates the coin dispensing device corresponding to the input coin type to dispense coins of the same type.

(F) Embodiment The figure shows a control circuit of a money processing unit according to the present invention. Coin switches 1A, 1B, 1C, and 1D corresponding to 10 yen, 50 yen, 100 yen, and 500 yen are activated by a microcomputer when a coin is inserted. Coin detection signals C ₁ , C ₅ , C ₁₀ , and C ₅₀ are output to ports P ₀ of 12. In this example, each 10 yen, 50 yen, 100 yen, and 500 yen coin dispensing device has a coin dispensing plate disposed below each coin storage pipe and a drive motor 3 that operates the dispensing plate.
It is composed of A, 3B, 3C, and 3D. The operation of the drive motors 3A, 3B, 3C, and 3D is controlled by coin dispensing signals _P1 , _P5 , _P10 , and _P50 for each coin type outputted from port _P1 of the microcomputer 12. Microcomputer 12
calculates the input amount by inputting coin detection signals C ₁ , C ₅ , C ₁₀ , and C ₅₀ , and when dispensing coins, outputs a coin dispensing signal.
P ₁ , P ₅ , P ₁₀ , P ₅₀ are OR gates 10A, 10B,
When the output is output through 10C and 10D, the output side of inverters 11A, 11B, 11C, and 11D becomes "L". Drive motors 3A, 3B, 3C, and 3D
works. And pulse switches 4A, 4B,
4C, 4D are drive motors 3A, 3B, 3C, 3D
It turns on and off in conjunction with
It turns OFF and generates "H", but turns ON due to motor drive and becomes "L", and then turns OFF again when the motor rotates the amount necessary for the coin dispensing plate to dispense one coin. It is configured to output "H". This pulse switch 4A, 4B,
4C and 4D are connected to the port _P2 of the microcomputer 12 through the OR gate 13, and the microcomputer 12 receives coin dispensing signals _P1 , _P5 , and
When the input signal to port P ₂ changes from "L" to "H" by outputting P ₁₀ and P ₅₀ , the coin dispensing signals P ₁ , P ₅ , and
By stopping the output of P ₁₀ and P ₅₀ , the drive motor 3
Controls the driving of A, 3B, 3C, and 3D. Furthermore, a test switch 2 is connected to port _P3 of the microcomputer 12. Incidentally, when there are a plurality of coin types to be paid out, the microcomputer 12 outputs a coin payout signal with priority given to higher coins. In addition, a flip-flop circuit 5 which is a test control means
For A, 5B, 5C, 5D, set terminal S is AND gate 6A, 6B, 6C, 6D, and reset terminal R is
AND gates 7A, 7B, 7C, 7D, output terminal Q are OR gates 10A, 10B, 10C, 10D
It is connected to the. And AND gate 6A, 6
The input sides of B, 6C, and 6D are connected to coin switches 1A, 1B, 1C, and 1D, respectively, and the test switch 2, and the input sides of AND gates 7A, 7B, 7C, and 7D are connected to flip-flop circuits 5A, 5, respectively.
It is connected to delay circuits 9A, 9B, 9C, 9D connected to output terminals Q of B, 5C, 5D and an OR gate 13.

The operation during testing with the above configuration will be explained. First, when the tester turns on the test switch 2 and inserts, for example, a 10 yen coin into the money handling section of the vending machine, the coin switch 1A turns on instantly and generates a coin detection signal _C1 , which is output to the AND gate 6A. A pulse is obtained and flip-flop circuit 5A is set. On the other hand, the coin detection signal _C1 is also introduced to the microcomputer 12, but the test switch 2 is turned on.
Since the test output "H" is input to port _P3 , no calculation is performed. Then, when the output side of the inverter 11A becomes "L" in the setting of the flip-flop circuit 5A, the drive motor 3A rotates,
The coin dispensing plate of the yen coin storage pipe operates to dispense 10 yen coins. Also, since the set output of the flip-flop circuit 5A is delayed by the delay circuit 9A and input to the AND gate 7A, the pulse switch 4A is turned on at this point due to the start of rotation of the drive motor 3A, and the set output of the flip-flop circuit 5A is input to the AND gate 7A.
is not reset. However, it turns ON at the start of rotation.
When the pulse switch 4A is turned off again by the withdrawal of a 10 yen coin and the output becomes "H", an output is obtained at the AND gate 7A and the flip-flop circuit 5A is reset. Therefore, inverter 1
Since the output side of 1A becomes "H", the drive motor 3A stops. Similarly, when 50 yen, 100 yen, and 500 yen are input, the corresponding flip-flop circuit 5
B, 5C, 5D are set and drive motors 3B, 3
C and 3D operate, and one coin is paid out each. Through this test operation, the tester can control the coin switches 1A, 1B, 1C, 1D, drive motor 3A,
3B, 3C, 3D pulse switch 4A, 4B,
Abnormalities in 4C, 4D and signal harness can be confirmed. When the tester turns off the test switch 2 at the end of the test, the microcomputer 12 enters the normal sales standby state and performs arithmetic operations based on the input of the coin detection signals C ₁ , C ₅ , C ₁₀ , and C ₅₀ .

Further, in this example, the test control means is configured as flip-flop circuits 5A, 5B, 5C, and 5D and is configured separately from the microcomputer 12, but the microcomputer 12 can also be provided with such a function. In this case, microcomputer 1
2, when the test switch 2 is in the ON state and any coin detection signal _C1 , _C5 , _C10 , _C50 is input, the coin dispensing signal _P1 , _P5 is sent to the corresponding drive motor 3A, 3B, 3C, 3D. - P ₁₀ and P ₅₀ are output, and the output is set to stop when the input signal of port P ₃ changes from "L" to "H". Furthermore, the present invention is also applicable to a coin dispensing device in which a coin dispensing plate is operated by a solenoid drive.

(G) Effects of the Invention According to the present invention, failure analysis can be performed with certainty since abnormalities in the money handling section of a vending machine can be tested separately from the control board, and it is possible to determine whether the cause of the abnormality is in the money handling section or whether the control You can easily find out whether it is on the component board or other terminals. Furthermore, since the test operation is accomplished by inserting a coin, it is easy to determine whether there is an abnormality in the money handling section in the market.
