Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a price setting device for a vending machine, and particularly to a price setting device that sets the selling price of a product by pressing a product selection switch a predetermined number of times.

When setting product prices in vending machines,
A method as shown in FIG. 2 or FIG. 2 is generally practiced.

That is, in FIG. 1, the same number of price setting switches 1, 1°, . . . , 1 as the types of products are used, and these switches 1, 1. ..., the setting output according to 1 is controlled by the control unit 2.
and perform subsequent predetermined operations such as comparison with the input amount.

In the method shown in the second diagram, the number of price setting switches 3, 3 . ..., 3, and these switches 3, 3 . ..., 3 is supplied to the matrix circuit 5 via the control unit 4, the correspondence between the type of product and the price is set by the matrix switch 5, and the setting output is sent according to the setting (not shown). Supplies the sales control circuit.

These methods have the disadvantage that it is necessary to increase the number of price setting switches as the types of products and the number of set prices increase, and therefore the number of inputs to the control section also increases.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a price setting device for a vending machine that is simple in structure and inexpensive.

The present invention provides a plurality of product selection switches, an operation mode switching device for switching the energization operation of these product selection switches to a pricing operation or a product sales operation, and an operation mode switching device for switching the energization operation of these product selection switches to a pricing operation or a product sales operation, and a switch for each of these product selection switches in the pricing operation mode. On the other hand, a price setting circuit that counts the number of activations of the product selection switch and sets a set price of the product assigned to the product selection switch in accordance with the number of activations, and a price setting circuit corresponding to each of the product selection switches. and a storage circuit which allocates an address in advance and writes the set price output from the price setting circuit to the address corresponding to the product selection switch of the product corresponding to the set price, and stores the product at the time of product sales operation. The present invention is characterized in that when a selection switch is energized, an address corresponding to the product selection switch is specified and a set price is read out.

The present invention will be described below with reference to the drawings.

An embodiment of the price setting device of the present invention is shown in FIG.

Here, only the portions of the control section of the vending machine that are related to price setting will be shown.

In the figure, reference numeral 11 indicates a control section of the vending machine, and reference numeral 12 indicates a control section of the vending machine.
indicates an operation mode changeover switch, and the operation mode changeover switch 12 is used to change over whether the control section 11 performs a product sales operation or a price setting operation.

Reference numerals 13 each indicate a product selection switch, and when the operation mode changeover switch 12 is in the price setting mode, the number of times the product selection switch 13 is pressed and energized is counted by a counting section 14 at the next stage.

The output from the counting section 14 is temporarily stored in the register 15 at the next stage.

Here, when the control unit 11 reads the accumulated contents of the register 15, the control unit 11 sets a price unit of X yen (for example, 1
0 yen, 50 yen, 100 yen, etc.).

Therefore, by pressing the product selection switch 13 for a selected product n times, the set price of the product, nx yen, is transferred to the control unit 11 from the count value of the counter 14 temporarily stored in the register 15 at the next stage. Obtained by reading.

This register 15 is controlled by a set switch 16 connected to the control section 11, and by pressing the set switch 16, the temporarily stored contents of the register 15 are read into the control section 11 and then written into the memory 18 via the memory interface 17.

That is, the product selection switches 13, 13 . ....

13 is input to the control unit 11 via a line not shown, so the control unit 11 stores the product selection switch 13 pressed n times as described above, and stores the memory corresponding to the stored product selection switch 13. The set price nx mentioned above is written to a predetermined address of 18 when the set switch 16 is pressed.

In addition, the reference numeral 19 in the figure indicates that the control unit 1 is
This is an auxiliary power supply circuit for protecting the storage circuit in 1 and the stored contents of memory 18.

However, if nonvolatile memories are used as these storage circuits, the auxiliary power supply circuit 19 is not necessary.

In this way, by pressing the product selection switch 13 the required number of times and then pressing the set switch 16, the price setting process of storing the product number and set price in the memory 18 is repeated for each product selection switch, and all prices are After completing the settings, press the operation mode selector switch 12.
Switch to product sales mode.

When selling a product, the control unit 11 selects a product number by pressing the product selection switch 13.
reads the set price from the memory 18 and uses it as a reference for comparing and determining the amount to be invested.

As described above, according to the present invention, the price can be set at the same time using the product selection switch and stored in the memory without providing a price setting switch. There is no need to provide a setting switch, thus simplifying the configuration of the price setting device and reducing the price of the device.

Moreover, since there is a one-to-one correspondence between a product and a set price for that product, the present invention can also be effective in preventing setting errors.
