Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a price setting device for a vending machine that sets a price by storing the selling price of a product in a memory.

(B) Conventional technology Conventionally, when setting the selling price in a vending machine, as shown in Japanese Patent Application Laid-open No. 5162800, the desired value is set by appropriately operating the switch corresponding to each bit of binary information. The selling price was set using binary information. Such a price setting device is not only expensive because the switch for setting binary information is relatively expensive, but also has a complicated circuit because the number of terminals of the electric circuit connected to the switch increases. Therefore, there is a price setting device that solves the above drawback by storing the selling price of a product in a memory.

Although it is far from the field of vending machines, Japanese Patent Application Laid-Open No. 50-3859
Publication No. 8 discloses a ticket issuing device having a structure in which the selling price printed on the ticket surface is stored in a memory when the ticket is issued.

(c) Problems to be Solved by the Invention However, according to the prior art, in order to set the price to be set in the memory, the numeric keypad and function keys must be operated mathematically according to a predetermined procedure. This has the disadvantage that setting operations are difficult.

The present invention provides a price setting device for a vending machine that can easily load selling prices for each product type into memory without using a numeric keypad or function keys.

(2) Means for Solving Problems To explain the present invention in detail with reference to the drawings showing an embodiment of the problem, the price setting device (4) is equipped with a push-button switch corresponding to the type of coins inserted into the vending machine. It has (4A) and (4B).

The push button type switches (4A) (4B) output a signal according to the amount of the corresponding coin by pressing the switch.
The price setting device (4) outputs price information based on the type of pushbutton switch to be pressed and the number of times the switch is pressed.

The memory (9) includes a predetermined storage section depending on the type of product. When setting the price, the central processing unit (6
) displays this when the price information is entered! ! (
3>, and also the product selection switch <5
) is operated, the input price information is loaded into the storage unit corresponding to this selected product.

(*)Price information can be created by operating the pushbutton switch according to the price to be set, and by operating the selection switch, this price information is stored in the storage section of the memory corresponding to a predetermined product. .

(f) In the example diagram, (1) is a changeover switch consisting of a rotary switch, etc., and the switch has a price data set contact (A) used when setting the price of the sold product, and a normal After setting the normal sales contact point (B) and price data that are always held during sales, an interface is used to check whether the desired product price has been definitely set in the EPROM (9) corresponding to the product code (described later). A price data reading contact (C), etc., which can be displayed and confirmed on a display device (3) connected to (2), etc. are provided. <4) is a price setting device that generates desired price information, such as a 10 yen signal or a 100 yen signal, when setting a product price, and is installed in the main body of a vending machine.

(5) is a product selection switch provided at the top of the front door of the vending machine corresponding to each product code. (
6) is the central processing unit CPU, which interfaces the operations of all devices in the vending machine (2A), (2B),
This is the main control device that integrates and controls via (2C). (
7) is a storage device ROM used for reading only, and the RO
M(7) stores all programs necessary for processing such as comparison calculations by CPU(6).

(8) is a read/write memory RAM, and ROM (7) is a read/write memory RAM.
) is a CP that performs processing such as comparison calculations based on program instructions.
This is a storage unit that stores the processing results of U(6). (9) is a nonvolatile memory EPROM, and the EFROM (9) is
The price information generated when the price setting device (4) is pressed is stored in the storage section corresponding to the desired selection switch (5) by pressing the desired selection switch (5). Reference numeral (10) denotes a coin sorting device for sorting coins inserted by a customer when purchasing a desired product and generating a signal for the amount of money.

Next, in the above configuration, the operation when setting the price will be explained first. Switch to the set contact (A), and then if you want to set the product price to, for example, 150 yen, switch to the price setting device (4
) for 10 yen and 100 yen, press the 10 yen button 5 times and 1 time.
By pressing the 00 yen button once, these price information is applied to the CPU (6) via the interface (2A), and this price information is also applied to the display device (3). The price setter, usually the vending machine manager, confirms the price displayed on the display device (3) and then presses the selection switch (5>) corresponding to the desired product column. The above price information (15
0 yen) can be memorized.

Next, after completing the series of price sets, or in the middle of the price sale for each of the links 11), the price set is completed 1. When you want to reconfirm the set price information of the product you are currently using, switch the movable piece (P) of the changeover switch (1) to the price information readout contact (C) and press the selection switch (5) for reconfirmation. The stored contents are displayed on the display device (3) via the CPU (6) and the interface (2A) from the price storage section of the E P ROM (9) corresponding to this press switch (5). It is possible to easily check the set price.

Next, in order to return to a normal sales state after setting prices for all product columns, the movable piece (P) of the changeover switch (1) must be
) to the normal sales contact (B), the CPU (6)
The predetermined processing performed within the system can be completed.

That is, when a customer purchases a product, all types of signals outputted from the coin sorting device (10) are stored in the RAM (8) via the interface (2B), and then the above-mentioned all signals are stored in the RAM (8) via the interface (2B). The CPU (6) compares and calculates the similar signal and the set price of the pressed selection switch (5), for example, the aforementioned 150 yen stored in the EPROM (9).As a result, it is determined that it is OK to sell the product. If so, a sellable signal is outputted to a predetermined product discharging device or the like via the interface (2C).

The program stored in the ROM (7) in -1- is as follows:
This is not a program that simply causes the CPU (6) to perform processing such as comparison operations on the contents stored in the RAM (8) and EP ROM (9). For example, if the multi-bend method allows multiple sales of products within the input amount, the product price of the product discharged from the product discharge device is subtracted from the total input amount stored in RAM (8), and If the CPU (6) issues a command to rewrite the subtraction amount with the display amount displayed by the display device before subtraction, and if the subtraction amount is enough to sell the same product or another product, then CPU (6) in standby state for next sale
Set. At this time, if the customer presses the escrow switch installed on the second part of the front door 4, the remaining amount will be returned in full to the coin return slot from the coin ejecting section equipped with the coin sorting device (10), etc. It is fJ, again, RAM
Needless to say, the programger 13 is configured so that the CPU can perform an operation such that all the stored contents in (8) are blanked out and the amount displayed on the display device is also set to "0".

The changeover switch used in this example is a low-return switch that is used to set price data, read price information, and switch contacts during normal sales. The present invention is not limited to the above-mentioned low-return switch as long as it is a switch or device that can perform the following functions.

(G) Effects of the Invention Since the price setting device of the present invention does not use a switch for setting binary information, even if the number of prices increases, the number of terminals in the electric circuit will not increase and the circuit will not become complicated. Then, price information is created by selecting and operating the push-button switch corresponding to the coin according to the amount of the price to be set, so you can set the price with almost the same feeling as actually counting coins and avoid input errors. do not have. Moreover, since the type of product for which the price is to be set is specified by the selection switch, input price information can be easily and reliably loaded into the storage section of the memory corresponding to the product.
