Description

[Detailed Description of the Invention] The present invention relates to a vending machine with a continuous vending function, and provides a device that can be used without problems even by customers who are not aware of the continuous vending function.

First, the continuous sales function that is the subject of the present invention will be explained.

That is, after the customer inserts money and sells the product by operating the selection switch, the amount counting device counts the remaining amount, and as long as this remaining amount is still greater than the product set price, the product can be sold again by operating the selection switch. It is a function.

Therefore, such vending machines do not automatically return change as change unless the remaining amount is below the product's set price, and if the remaining amount is above the product's set price and the customer does not wish to continue selling, please operate the return switch. You must indicate your intention to return the change.

However, while customers who are aware of continuous vending will easily operate the return switch, customers who are not aware of this may be confused and may complain to the manager that the vending machine is malfunctioning.

In particular, it is easy to predict that such a situation will occur frequently in a vending machine that allows the insertion of high-value currency such as banknotes.

From this point of view, the present invention is a vending machine equipped with a continuous vending function, in which the customer operates the selection switch again even after a predetermined time has elapsed when the remaining amount after dispensing the product is more than the set price of the product. If the customer does not express his/her intention, the remaining amount will be automatically returned.

One embodiment will be described in detail below with reference to the drawings.

The figure shows the circuit of the present invention in a block diagram.

Reference numeral 4 denotes an amount introducing pulse generator which, when detecting the insertion of money, outputs the number of pulps corresponding to the amount to the amount counting device 1, and the amount counting device 1 adds and counts the amount of money inserted and subtracts the remaining amount after sending out the product. For example, a reversible counter.

Therefore, when a calculation pulse is introduced into the a-end, an addition operation is performed, and when it is introduced into the b-end, a subtraction operation is performed.

The count contents of the amount counting device 1 are decoded by the decoder 5 and outputted to the sales control circuit 2.

In the sales control circuit 2, a product setting price is set by a manual switch, and the amount counted by the amount counting device 1 and this product setting price are compared, and if the counted amount is larger, a sales enable output 6 is generated.
is generated in the selection circuit 7.

The selection circuit 7 becomes operable by the sales enable output 6, and when the customer operates the selection switch, the selection signal 8 is sent to the sales control circuit 2.
Output to.

The sales control circuit 2 outputs a calculation pulse corresponding to the selected product amount to the b end of the amount counting device 1, and also outputs a sales signal 10 to the product sending section 9.

In the operation so far, flip-flop circuit FF1
FF2 and FF2 are both reset in their initial state and do not make any contribution; however, upon the arrival of this sales signal 10, the flip-flop circuit FF1 is first set.

Then, the amount counting device 1 calculates the remaining amount according to the calculation pulse inputted to the b terminal, and since this remaining amount is still larger than the set price of the product and further sales are possible, the sales control circuit 2 generates a sellable output 6, and the flip-flop circuit FF, AND output 11 is generated and flip-flop circuit FF2 is set.

When the flip-flop circuit FF2 is set, the AND gate 12 is opened and the clock pulse from the clock pulse generator 13 is input to the counter 3, and time is counted.

The flip-flop circuit FF2 is reset when the sales signal 10 is output from the sales control circuit 2.
That is, a period of time is counted from when the sales control circuit 2 generates the sales enable output 6 based on the remaining amount until the customer, who has an intention to sell continuously, operates the selection switch again and the sales signal 10 is output.

Therefore, the counting capacity of the counter 3 is set so as to be able to count the sufficient time required during this period.

Therefore, when the customer has no intention of making continuous sales, the selection switch is not operated and the sales signal 10 is not generated, and the counter 3
The counting operation remains maintained.

Then, when a carry signal 14 is generated from the counter 3 after a predetermined period of time has elapsed, this signal becomes a command to return the remaining amount.

Furthermore, when the customer indicates his/her intention to continue selling by operating the selection switch within a predetermined time, the sales signal 10 is generated, the flip-flop circuit FF2 is reset, the counting operation is stopped, and the counter 3 is reset to zero by the Q output. .

The flip-flop circuit FF1 is reset by the detection output 15 when the decoder 5 detects that the amount counted by the amount counting device 1 becomes zero due to delivery of goods or payout of change.

Of course, it would be more effective if the device of the present invention was also equipped with a return switch, which is provided in conventional vending machines, to cover customers who are unaware of continuous vending.

Therefore, the flip-flop circuit FF2 is configured so that the detection output 15 of the decoder 5 is also reset.

That is, when the customer operates the return switch without losing the intention of selling continuously, the remaining amount is paid out and the amount counting device 1 is reset when it reaches zero.

Although the counter 3 is used as the return command circuit in this embodiment, it may be replaced with other elements or delay circuits as long as it can perform a timer operation.

The present invention described in detail above relates to a vending machine that waits for the customer's predetermined purchasing action without automatically returning the remaining amount after the sale is still greater than the product's set price, and is intended for customers who are not aware of continuous sales. If the customer does not make a purchase after a predetermined period of time has elapsed, the remaining amount will be automatically returned to provide relief to such customers.
