[Technical field to which the invention pertains]

The present invention relates to a system equipped with a plurality of vending machines (also abbreviated as vending machines) and a center device that collects sales information from each of the vending machines via a transmission line. Note that in the following figures, the same reference numerals are the same or equivalent. Show parts.

[Prior art and its problems]

Figure 4 is a schematic diagram of the entire system of this type, and Figure 3 (
1) is an explanatory diagram of the main functions of the conventional vending machine shown in FIG. 5, and FIG. be. In FIG. 4, v (v1 to VN) is a vending machine, Z is a center device, and L is a transmission line. For example, the center device Z sequentially transmits a sales information transmission request RQ to each vending machine V at a predetermined time interval, thereby transmitting the sales information SD sent by each vending machine V.
Collect information and perform data processing such as aggregation. Next, in FIG. 3 (1), KB is a product information setting means such as a keyboard, and a product information recorder consisting of RAM, etc.
First, the product information DA is set and stored in the MA for each product sales column (not shown), that is, for each column number CN, as shown in FIG. 2 (2). Note that the product sales column here refers to a storage shelf for sales products that is combined with a means for transporting products (not shown), and also refers to the product information DA.
What is sales product identification code DA (DAI), unit price DA
(DA2) etc. The MB inputs the sales signal VS that is output corresponding to each product sales column for each product sale into the sales number storage means consisting of the same RAM, etc., and stores the sales signal VS in each product sales column (therefore, The number of sales for each column number CN), that is, the sales number DB is stored cumulatively. The product information DA and sales number DB are sent to the center device Z as sales information SD via the sales information sending means 1 in response to a transmission request RQ from the center device Hz, and the sales number DB is cleared each time. In this way, the previous transmission request RQ by the center device Z
The sales information from the current transmission request to the current transmission request is collected by the center device Z. However, such a system has the following problems. In other words, when replacing the type of product, the product information DA (product identification code,
unit price, etc.), but if you simply change them, the number of sales of the product after the replacement will be added to the number of sales of the product immediately before the replacement, and this added sales number will be the number of sales of the product after the replacement. Since the sales information will be sent to the center device as the number of sales, and the sales contents will be incorrect, after sending the sales information SD for the product before replacement to the center device, the storage contents in the sales number storage means MB (sales number DB) will be sent to the center device. ) must be cleared before changing the product information DA. Due to the above-mentioned restrictions, when changing the product information DA, make sure that no sales occur between the time the sales number DB is cleared and the time the product information DA is changed. This has to be done at the timing immediately after sending out, which limits the time for product change (replacement) and the time for change work, making the conventional system extremely difficult to use. Ta.

[Purpose of the invention]

The key point is to ensure that sales information does not become distorted even when the sales information is changed. In other words, the gist of the present invention is a sales system that includes a plurality of vending machines and a center device that collects sales information generated by each vending machine via a transmission line and performs data processing such as sales aggregation. In the information collection system, each of the vending machines described above includes a product information storage means (product information memory, etc.) that stores product information such as a product identification code and unit price for each product sales column, and a product information memory that stores the number of sales for each product sales column. A sales number storage means (sales number memory, etc.) for storing cumulative totals; a product information setting means (product information setting keyboard, etc.) for setting and inputting product information in the product information storage means; and product information in the product information storage means. and a sales information save storage means (sales information save memory, etc.) that saves and stores the sales numbers in the sales number storage means, and when the product information is updated via the product information setting means, the update is performed. Saving the product information and sales numbers for at least the relevant product sales column in the immediately preceding product information storage means and sales number storage means to the sales information saving storage means, and saving the sales numbers in the sales number storage means. Clearing means (CPU, ROM, etc.) and
When the center device collects sales information, if there is saved information in the sales information save storage means of the vending machine,
In addition to transmitting the information to the center device, the save information in the save storage means is cleared, and if there is no save information in the save storage means, the product information and the sales number in the product information storage means are cleared. The present invention includes means (such as a CPU, ROM, or serial interface) for transmitting the sales number in the storage means to the center device and clearing the sales number.
