Description

Description: TECHNICAL FIELD The present invention relates to a vending machine provided with a cash processing machine for processing inserted money, and controlling the money processing machine by a control circuit.

[Prior Art] A vending machine provided with a cash processing machine for processing inputted money and controlling the money processing machine by a control circuit is provided when a failure such as rainwater or foreign matter intrudes into the money processing machine. ,
A malfunction may cause an abnormality such as a large amount of change being released due to a malfunction.

Such an abnormality is because even if an abnormal signal is transmitted from a money handling machine that handles money to a control circuit that performs operations such as change, the control circuit cannot distinguish between normal and abnormal. When a flaw in a vending machine system was discovered, it was sometimes deliberately mischievous.

[Problems to be Solved by the Invention] An object of the present invention is to provide a vending machine which can prevent mischief performed by knowing such a disadvantage of a vending machine system and which can be used with ease.

[Means for Solving the Problems] The present invention provides a processing circuit that outputs a signal corresponding to the amount of money input, a first communication circuit that transmits a signal from the processing circuit to the vending machine body, A money handling machine comprising a money dispensing circuit for outputting a signal for paying out predetermined money according to a signal from the processing circuit; and a second communication circuit connected by communication with a first communication circuit of the money handling machine. And a change signal to be paid out from the price difference between the signal from the cash handling machine input through the second communication circuit and the product selected by the customer, is output to the cash handling machine. Input a signal from the machine and determine whether this signal is normal or abnormal.
The problem is solved by forming a vending machine with a vending machine body comprising a control circuit for outputting an abnormal signal and a relay for shutting off the power of the money handling machine in response to the abnormal signal from the control circuit.

[Operation] When an abnormality such as rainwater enters the cash processor, an abnormal signal is output from the cash processor to a control circuit, and the control circuit checks whether the input signal from the cash processor is normal. It is determined whether there is an abnormality, and in the case of an abnormality, the power of the money handling machine is shut off and the operation of the money handling machine is stopped.

Therefore, it is possible to prevent an abnormal operation such as stopping the operation of the money handling machine and carrying out a large amount of change.

[Embodiment] The present invention will be described with reference to an embodiment shown in the drawings. FIG.

In the figure, the vending machine includes a vending machine main body A and a money processing machine 1 built in the vending machine main body A. The money processing machine 1 transmits a signal to and from the vending machine main body A side. , A processing circuit 3 for inputting a signal from the communication circuit 2, and a change dispensing circuit 4 for dispensing change operated by the signal of the processing circuit 3.

Further, the vending machine main unit A has a control circuit 5, a second communication circuit 9 for transmitting a signal of the control circuit 5 to the first communication circuit 2 of the cash processing machine 1, and an opening and closing operation by a signal from the control circuit 5. A relay 7 is provided. The plug 6 is also connected. When the plug 6 is connected to a power supply, the control circuit 5 operates and the signal of the control circuit 5 closes the contact 8 of the relay 7 to connect the money handling machine 1 to the power supply.

A signal normally generated in the processing circuit 3 of the money processor 1, for example, a signal of the inserted money is output to the control circuit 5 via the first communication circuit 2 and the second communication circuit 9. The control circuit 5 determines this signal as a normal signal, compares it with, for example, a signal of the price of the product selected by the customer, and compares the difference signal with the second communication circuit 9 and the first communication circuit 2. Output to the processing circuit 3 via the The processing circuit 3 receives this signal, outputs a signal to the cash dispensing circuit 4, and pays a predetermined difference.

However, if the first communication circuit 2 or the processing circuit 3 of the money handling machine 1 malfunctions, the control circuit 5 determines that this is abnormal and opens the contact 8 of the relay 7 to turn off the power to the money handling machine 1. Shut off to stop malfunctions such as unnecessary change payment.

In other words, the determination between abnormal and normal is made by normalizing a series of computational operations such as paying out the difference between the inserted money and the product selected by the customer as change as described above, and performing such a calculation. If a signal that cannot be obtained is generated, it can be easily determined that the signal is normal or abnormal by determining that the signal is abnormal.

Such a determination is made by the processing circuit 3 and the control circuit 5
You can easily do this by setting up programs for each.

In addition, the program stores a numerical value such as an amount of money to be generated, and when a numerical value other than the stored numerical value occurs, configures a program that is regarded as abnormal to function as an abnormality detection. Can be.

As another method, when the control circuit 5 is provided with all the instruction systems such as calculation of change and payment of goods, the change processing machine 1 simply handles money.

In this case, since a command for inquiring whether or not money has been inserted is periodically transmitted from the control circuit 5, it is possible to determine that an abnormality has occurred when an abnormal answer is returned.

[Effects of the Invention] According to the present invention, it is possible to obtain a vending machine which can prevent mischief performed by knowing the disadvantages of the vending machine system and can be used with peace of mind, and the effect is extremely large.
