Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an operation method in a vending machine, etc. that has a plurality of operation buttons on the customer service side and enables only one of the operation buttons when two operation buttons are operated at the same time. button 2
Related to heavy operation prevention device.

Conventionally, in vending machines that have multiple operation buttons on the customer service side and sell goods or tickets as appropriate when the operation buttons are operated, when two operation buttons are operated at the same time, The switches of the respective operating buttons are connected in series so that only one of them becomes effective, so that when one of the operating buttons is operated, the circuits of the other operating buttons are no longer configured.

With this method, when two operation buttons are operated at the same time, only one of the operation buttons becomes effective, and there is no problem.
If you press and release two operation buttons momentarily with a slight shift in time, the item or ticket corresponding to one operation button will be sold, and the change that was generated when you operated the other operation button will be released. Sometimes it happened.

In view of the above, the present invention provides a device for preventing double operation of operation buttons, which enables only the operation of the operation buttons by one person to be effective even if the operation buttons are operated at the same time or momentarily after being slightly shifted. For the purpose of providing.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

Reference numeral 1 denotes a memory calculation circuit which calculates and stores the amount of coins inserted into the vending machine, and sends out a binary amount signal 2 corresponding to the amount inserted.

Also, when the operation button on the customer service side is operated, change is calculated.

3 is a scanning circuit, which includes a pulse generator 4, a flip-flop circuit 17, a gate circuit 6, a signal conversion circuit 7 that converts the pulses from the pulse generator 4 into binary code, and a binary account signal 5 from the signal conversion circuit 7. It is comprised of an account designation circuit 10 and the like that converts the signal into a decimal account signal 12.

8 is a signal conversion circuit for converting the binary account signal 5 from the scanning circuit 3 into an amount signal 16;
When a 50 yen item or ticket is sold by operating the 0 seat operation button, when a binary account signal 5 representing 10 seats is input, that signal is converted into a signal corresponding to 50 yen.

9 is a comparison circuit that compares the amount of signal 16 from signal conversion circuit 8 with the amount of signal 2 from storage calculation circuit 1, and determines that the amount of signal from signal conversion circuit 8 is less than the amount of signal from storage calculation circuit 1. Signal A is output when .

11... is a gate circuit that opens the gate using the decimal account signal 12 from the account designation circuit 10 of the scanning circuit 3 and the signal from the comparison circuit 9, and is provided for each account, that is, for each operation button. .

Lamps 15 are connected in parallel to the gate circuits 11 through operation button switches 13 and flip-flop circuits 14.

In such a circuit configuration, when coins are inserted and the first coin is counted, in the scanning circuit 3, a pulse is generated from the pulse generator 4, and the flip-flop circuit 17 is set.

This opens the gate of the gate circuit 6 and inputs the pulse from the pulse generator 4 to the signal conversion circuit 7.

The signal conversion circuit 7 converts the pulse into a binary code and sends out a binary account signal 5.

The binary account signal 5 is converted into a decimal account signal 12 by an account designation circuit 10 and sent to a gate circuit 11 .

On the other hand, this binary account signal 5 is converted by a signal conversion circuit 8 into a binary amount signal 16 corresponding to the amount pressed by the operation button, and sent to a comparison circuit 9.

Even if money is inserted, when the input amount signal 2 is not outputted from the memory calculation circuit 1, the signal A is not outputted from the comparison circuit 9.

Therefore, the gates of the gate circuits 11... are closed and the lamps 15 are not lit.

Here, signal 2 corresponds to the amount of money counted first.
When the amount is input from the storage/arithmetic circuit 1 to the comparison circuit 9, that amount is compared with the amount for each account from the signal conversion circuit 8.

As a result of the comparison, if the amount from the signal conversion circuit 8 is less than the amount of the inserted money, a signal A is sent from the comparison circuit 9.

When this signal A is sent out, a signal A' to which other conditions have been added is input to the gate circuit 11.

This signal A' and the scanned decimal account signal 12 from the scanning circuit open the gate circuits 11 corresponding to the input money amount or less, set the flip-flop circuits 14, and set the lamps. 15...
lights up.

In this way, as money is inserted, the lamps 15 . . . within the total amount of money inserted are lit to inform the customer of the items or tickets that can be purchased.

For example, the price of the item sold by operating the operation button of 10 seats is 40 yen, the price of 20 seats is 60 yen, etc.
If a 10 yen coin is inserted, the price of 10 seats will be 40
The comparison circuit 9 does not send signal A because the amount is higher than the input amount of 10 yen.

Therefore, even if the signal X is not input to the gate circuit 11... and the decimal account signal 12... is scanned and input to the gate circuit 11...
closes the gate, and lamp 15... does not light up either.

Next, coins are inserted and the total amount is the price of 10 coins 4
When the value reaches 0 yen, a signal indicating 10 points is output to the binary account signal 5, that is, the signal 2 from the memory calculation circuit 1 is output.
When and the signal 16 from the signal conversion circuit 8 match, the comparison circuit 9 sends out the signal A, and the signal A'75i is inputted to the gate circuits 11 . . . .

At this time, only the signal 12 of the 10 points is sent from the scanning circuit 3 to the gate circuit 11, so only the gate circuit 11 of the 10 points is opened, the flip-flop circuit 14 of the 10 points is set, and the gate circuit 11 of the 10 points is opened. The lamp 15 is turned on.

When the signal of 20 points is output to the binary account signal 5, the price of 20 points is 60 yen, which exceeds the input amount of 40 yen, so signal A is not sent from the comparison circuit 9, and the gate of the gate circuit 11 of 20 points is I can't open it.

Therefore, the 20 lamps 15 are not lit either.

Similarly, the lamps 15 with 30 seats or less do not light up.

Even if the scanning circuit 3 no longer sends the 10 signals 12, the flip-flop circuit 14 remains set and the 10 lamps 15 continue to light up.

As the money is sequentially inserted in this manner, the lamps 15 of the operation buttons whose amount is less than the total amount of money input are lit, and the customer is informed of the operation buttons that can be operated.

The customer operates one of the operation buttons on which the lamp 15... is lit, but until the operation button is operated, the gate circuit 11... does not perform the scanning of the scanning circuit 3. Each time the trigger signal 12 is sent, the gates are sequentially opened and closed for items within the total input amount.

If the ten operation buttons are operated, the ten switches 13 are closed.

At this time, when the scanning circuit 3 is not sending out the signal 12 for the tenth position, the gate circuit 11 for the tenth position is closing the gate, so the switch 13 for the tenth position is activated.
The circuit for the operation button at position 0 is not configured.

However, when the scanning circuit 3 is scanned and the 10 signals 12 are sent out, the 10 gate circuits 1
1 is opened, and a circuit of 10 operation buttons is configured.

When the circuit of this operation button is configured, the flip-flop circuit 17 of the scanning circuit 3 is reset by the signal B, and the gate of the gate circuit 6 is closed.

Therefore, the pulses from the pulse generator 4 are no longer input to the signal conversion circuit 7, and thereafter the signal conversion circuit stops transmitting the account signal of the operated operation button.

At the same time as this operation button is operated, the flip-flop circuit 14...
... is reset and the lamp 15... is turned off, but the lamp 15 of the operated operation button continues to be lit because the gate of the gate circuit 11 of the operated account is open.

On the other hand, depending on the circuit configuration of the operation button, goods or tickets are sold, change is calculated, and change is released.

When the articles or tickets and change have been dispensed, the pulse generator 4 no longer sends out pulses, the flip-flop circuit 17 is set, and the set flip-flop circuit 14 is reset to be ready for sale.

Furthermore, when an operation button is operated that exceeds the total input amount, the comparison circuit 9 does not send signal A, so the gate of the gate circuit 11 of the operated operation button is not opened, and the switch 13 of the operation button is closed. However, the circuit for that operation button is not configured.

In this way, the accounts of the operation buttons are sequentially scanned, and as soon as the operation button is operated, the scanning is stopped at the account of the operated operation button, and then the goods or tickets corresponding to the operated operation button are scanned. The system calculates the change and sends the change, so for example, even if two operation buttons are operated at the same time, only the account scanned first will be valid, and the item for sale and the change will be different. In addition, even if the two operation buttons are pushed and released momentarily with a slight lag in time, only the account scanned first will be valid, and sales items and change will be processed as described above. There is no difference between

As is clear from the above configuration, according to the present invention, even if two or more operation buttons are operated at the same time or almost simultaneously in any state, only one of the operation buttons becomes effective. There are no different items or tickets or different change.
