The storage area 23e is an area for storing sales summary data such as cumulative sales amount and cumulative sales count for each product code,
According to the setting of the product code, a sales total data storage unit corresponding to the set number is provided.

 The operation of the vending machine 5 having the above configuration will be described.

(Setting Mode) The operation in the setting mode will be described with reference to the flowchart in FIG. 5A.

First, in step S1, the CPU 21 supplies a drive signal to the barcode reader 1, whereby the barcode reader 1 can read a barcode. Then, when the barcode is input in step S2, the CPU 21 proceeds to the next S
In each of steps S3, S4, S5, and S6, the type of the input barcode is determined.

In step S3, if it is determined that the barcode input in step S2 is a JAN code, step S15
Proceed to processing. In step S15, the CPU 21
The product code included in the N code is extracted, and it is determined whether the same product code is stored in the storage areas 23b and 23c of the RAM 23. If it is stored, the process proceeds to step S16, and the column indicator 19 and the selection switch indicator 20 corresponding to the product code are driven. That is, the CPU 21 detects the product selection switch 8 storing the product code from the storage area 23b, and selects the selection switch indicator corresponding to the product selection switch 8.
The display data instructing the drive of 20 is stored in the selection switch indicator display buffer of the RAM 23 and output to the display device 14. Further, the CPU 21 detects the product storage column 2 storing the product code from the storage area 23c, and displays display data for instructing driving of the column indicator 19 corresponding to the product storage column 2 in the column of the RAM 23. The data is stored in the indicator display buffer and output to the display device 14.

If it is determined in step S15 that the corresponding product code is not stored in the storage areas 23b and 23c, the process proceeds to step S17, where the product code is stored in the product code buffer.

If it is determined in step S4 that the barcode input in step S2 is a column code,
Proceed to step S18. In this step S18, it is determined whether or not the product code is stored in the product code buffer,
If stored, the process proceeds to step S19. Step S19
In the CPU 21, the storage area 23c of the RAM 23
This product code is stored in the address corresponding to the product storage column 2 indicated by the column code. On the other hand, if the product code is not stored in the product code buffer, error processing is performed in step S20, and the process returns to step S1.

If it is determined in step S5 that the barcode input in step S2 is a sales price code, the process proceeds to step S21. In step S21, it is determined whether or not a product code is stored in the product code buffer. If the product code is stored, the process proceeds to step S22. If not, an error process is performed in step S23.

In step S22, the CPU 21 stores the product code stored in the product code buffer and the barcode indicating the selling price read by the barcode reader 1 in the storage area 23d of the RAM 23. In this way, the barcode printed on the product 18 for which the selling price is to be set is read by the barcode reader 1, and then the barcode indicating the selling price to be set is selected from the sheet 30 and the barcode is selected. By reading with the reader 1, the correspondence between the product and the selling price is stored in the RAM 23.

If it is determined in step S6 that the barcode input in step S2 is a product selection switch code, the process proceeds to step S8.

Thus, the product selection switch 8 can be specified by directly operating the product selection switch 8 in addition to reading the product selection switch code with the barcode reader 1. Therefore, if it is determined in step S6 that the code is not a product selection switch code, the process proceeds to step S7, where it is determined whether the product selection switch 8 has been operated. If the product selection switch 8 has been operated, the process proceeds to step S8.

In step S8, it is determined whether or not the product code is stored in the product code buffer. If the product code is stored, the process proceeds to step S9, but if not, an error process is performed in step S20.

In step S9, the CPU 21 determines from the display data stored in the selection switch indicator display buffer whether the selection switch indicator 20 corresponding to the product selection switch 8 is being driven. Then, when the corresponding selection switch indicator 20 is being driven, the step
Proceed to step S10. In step S10, the contents stored in the storage area 23b of the RAM 23 at the address corresponding to the product selection switch 8 are cleared. In the next step S11, the CPU 21 stores display data for turning off the selection switch indicator 20 corresponding to the product selection switch 8 in the selection switch indicator display buffer and outputs the display data to the display device 14.

However, if the selection switch indicator 20 corresponding to the indicated product selection switch 8 has not been driven, the process proceeds to step S12. In this step S12,
The CPU 21 stores the product code stored in the product code buffer at the address corresponding to the product selection switch 8 in the storage area 23b of the RAM 23. Then, in the next step S13, the CPU 21 stores display data for turning on the selection switch indicator 20 corresponding to the product selection switch 8 in a selection switch indicator display buffer and outputs the display data to the display device 14.

In this manner, the bar code reader 1 reads the JAN code, and then reads all the column codes corresponding to the product column storing the product, thereby reading the storage area 23c corresponding to the specified product storage column 2. The product code included in the JAN code is stored in the address. Further, the JAN code is read by the bar code reader 1, and then the bar code reader 1 reads all the product selection switch codes corresponding to the product selection switch 8 corresponding to this product, or the product selection switch 8 directly. Is operated, the product code included in the JAN code is stored in the address of the storage area 23b corresponding to the specified product selection switch 8. At this time, the JAN code is read by the barcode reader 1, and subsequently, the designation of the product selection switch 8 and the designation of the product storage column 2 are performed continuously. And the product code can be handled together. At this time, if the bar code is read from the sheet 30, the correspondence between the product code and the selling price can be performed at the same time.

Then, in step S14, the mode switch 18
It is determined whether or not the setting has been completed by the above operation again. If the setting has been completed, the vending machine 5 enters the vending mode. However, if the processing has not been completed, the process returns to step S1.

(Sale Mode) Next, the operation of the vending machine 5 in the sale mode will be described in 5B.
This will be described with reference to the flowchart in FIG.

In step S100, the CPU 21
, It is determined whether a signal indicating the amount of the inserted coin has been sent, and if it has been sent, this amount is added to the amount stored in the inserted amount buffer in the next step S101. In the next step S102, it is determined whether or not the product selection switch 8 has been operated to select a product. If the product selection switch 8 has been operated, the process proceeds to step S103. In step S103, the product code corresponding to the selected product selection switch 8 is detected from the storage area 23b of the RAM 23 and stored in the product code buffer. Next, step S1
In 04, the sales price of the product is searched from the storage area 23d of the RAM 23 based on the product code stored in the product code buffer, and the sales price is compared with the input amount stored in the input amount buffer. It is determined whether the selected product is available for sale.

If the selected product is available for sale, the process proceeds to step S105. Based on the product code stored in the product code buffer, the product storage column 2 storing the product is searched from the storage area 23c of the RAM 23. . Next step S1
In 06, sales control processing is performed, and the CPU 21 controls the product sending operation by giving a drive signal to the product sending drive motor corresponding to the searched product storage column 2 and calculates change and, if necessary, coins. The change dispensing operation of the processing device 11 is controlled.

Upon completion of the selling operation, the CPU 21 performs the process in step S107. In this step S107, it is determined whether or not the product code stored in the product code buffer is stored in the storage area 23e of the RAM 23. Then, if the product code is stored, that is, if the address for storing the sales summary data for this product code is set in the storage area 23e, the process of step S108 is performed. In step S108, CPU 21 adds the sales data in the selling operation to the sales total data stored in the sales total data storage unit corresponding to the product code, and then returns to the process in step S100.

However, when the product code stored in the product code buffer is not stored in the storage area 23e of the RAM 23, the process of step S109 is performed, the product code and the sales data are stored in the storage area 23e, and the process of step S100 is performed. Return to
As a result, the CPU 21 sets the sales total data storage unit corresponding to the product code in the storage area 23e and, at the same time, stores the first sales total data in the storage unit.

(Sales aggregation mode) By operating the aggregation switch 32, the aggregation data stored in the storage area 23e can be printed out by the printer unit 31. This operation will be described with reference to the operation in FIG. 5C.

First, in step S50, the CPU 21 supplies a drive signal to the barcode reader 1, and when a barcode is input in the next step S2, the code input in step S52 is JAN.
Determine if it is a code. If it is determined that the code is a JAN code, the process proceeds to step S53. In step S53, the CPU 21 extracts the product code included in the JAN code and determines whether the same product code is stored in the storage area 23e of the RAM 23, that is, the sales code is stored in the storage area 23e corresponding to the product code. It is determined whether the total data storage unit is set.

If the same product code is stored in the storage area 23e, the CPU 21 proceeds to the process of step S54, reads out the sales total data from the sales total data storage unit corresponding to this product code, and stores it in the print buffer of the RAM 23. And outputs it to the printer unit 31. As a result, the printer unit 31 is driven to print out a sales summary table as shown in FIG. 6, for example. This sales summary table also shows that the products with the codes shown in the table have a selling price of 100 yen and are stored in the respective product storage columns of Nos. 1, 2, and 3. Therefore, in the setting mode, following the reading of the JAN code, while specifying the product storage columns of Nos. 1, 2, and 3, and entering 100 yen as the selling price, such a sales summary table is printed out. Vending machine. Further, the product name can be printed out on the sales summary table. To do this, the product code and the product name are stored in the RAM 23 in association with the product code that can be sold by this vending machine in advance, and when the product code is input in the sales aggregation mode, the corresponding product name is read and printed. It should just be out.

In this manner, by performing the sales totalization by reading the JAN code, it is possible to know only the sales totalization data of the product whose totalization is desired to be confirmed, thereby eliminating waste of printer paper.

Then, in step S55, it is determined whether or not the totaling of sales has been completed by operating the totalizing switch 32 again. If the totaling has been completed, the vending machine 5 enters the sales mode. However, if the processing has not been completed, the process returns to step S50.

The present invention described in detail above can also perform sales totaling for each product group in order to collectively manage sold products by their product codes. To explain this in the vending machine 5 of the embodiment, all the product codes belonging to the same group are stored in an appropriate storage area of the RAM 23 in advance, and any one of the product codes (JAN Code) is input, the CPU 21 reads out the total sales data of all the product codes belonging to this group from the storage area 23e, sums them up, and prints out the totals. Become.

In addition, there are vending machines that aggregate sales using an electromagnetic counter.In such a case, the electromagnetic counter and the product code are stored in advance in the RAM 23 in association with each other, so that the total management for each product code can be performed. This can be done with an electromagnetic counter.

(G) Effect of the Invention According to the present invention, when the same product is stored in a plurality of product storage columns, the sales summary data for each product code is stored in the memory means. Thus, the sales management for each product can be performed only by reading the sales summary data of the product.
