Description

The present invention relates to an electronic cash register suitable for managing sales data for each customer.

[Prior Art] Generally, as a service system for consumers, a discount of several% is given when a product over a certain amount is purchased,
A system is widely applied in which a voucher called a service voucher is issued according to the purchase price and replaced with a discount. Further, even more services are required for customers who always use the service, and for example, they have provided services such as sending advertisement paper or the like containing product information to each customer.

[Problems to be solved by the invention] However, in these service systems, the cashier must calculate the discount amount each time and issue the service ticket in the number corresponding to the purchase amount, which is a complicated task. I was forced to. On the other hand, the customer also had to save the service ticket by pasting it on a sheet, which was a hassle and was not a sufficient service system.

Therefore, the present invention can automatically calculate a predetermined service amount (sales status data) according to each customer's purchase amount and cumulatively manage it for each customer. It is an object of the present invention to provide an electronic cash register which can be converted into cash and which can realize a sufficient service system without the cashier and the customer being forced to perform complicated work.

[Means for Solving the Problems] As shown in FIG. 1, the present invention relates to an electronic cash register which performs registration processing of product sales data of one customer inputted from an input unit and prints out by a printer. A sales status data memory A which forms an area for storing sales status data corresponding to each customer number set for each customer, and a customer memory B which stores the total amount of product sales data of one customer. Customer number registration means C for registering the customer number of one customer, customer number memory D for storing the customer number registered by the registration means C, and a closing key E for closing the registration process for one customer. When the closing key E is operated and input, a first judging means F for judging whether or not the customer number is registered in the customer number memory D, and the customer number by the first judging means. If it is determined that the number is registered, the data conversion means G for converting the total amount data stored in the customer memory B into the sales status data, and the sales status data calculated by the conversion means G are stored in the sales status data memory A. Sales status data accumulating means H for cumulatively processing the area corresponding to the customer number registered in the customer number memory D, cash exchange demand amount input means I for inputting the cash exchange demand amount from the customer, and cash exchange by this input means I. When the requested amount is input, the second judging means J for judging whether or not the customer number is registered in the customer number memory D, and the second judging means J judges that the customer number is registered. The comparison means K for comparing the sales status data in the area corresponding to the customer number registered in the customer number memory D of the sales status data memory A with the cash conversion request amount, and this comparison means K Is that a sales situation data update means L to reduce the cash requested amount from the sales situation data in the case near the top situation data is large.

[Operation] With the present invention having such a configuration, the customer number registration means C
When the customer number of one customer is registered, the registration number is stored in the customer number memory D. Further, when the sales data of all the products purchased by the customer is input from the input unit, the total amount of the sales data of all the products is stored in the customer memory B. Then, when the closing key E is operated, the customer number is registered in the customer number memory D, so the total amount data stored in the customer memory B is converted into sales status data. Then, the sales status data is cumulatively processed in the area corresponding to the customer number registered in the customer number memory D of the sales status data memory A. Therefore, the sales status memory A stores the cumulative value of the sales status data generated for each shopping corresponding to the customer number set for each customer.

Therefore, when the customer requests cash conversion for the cumulative value of the sales status data, the cash conversion request amount input means I inputs the cash conversion request amount. Further, the customer number registration means C registers the customer number of the customer. Then, the sales status data in the area corresponding to the customer number registered in the customer number memory D of the sales status data memory A is compared with the requested cash amount, and if the sales status data is larger, The amount of money required for cashing is reduced and cash is redeemed.

A flag is set to 5, and the sales amount for each department is accumulated in the total amount memory 42 for each department. At the same time, the sales amount is added in the customer memory 41. After that, when the total key 23 is input, the total amount of money in the customer memory 41 is displayed. Here, if the customer number flag is set, the total amount is multiplied by a constant to calculate the service amount, and the service amount is accumulated in the customer number area of the sales status data memory 44 to obtain the total service amount. Is stored as

On the other hand, when the customer requests the cash conversion of all or a part of the total service amount, the cashier inputs the cash conversion key 25. Then, it is determined whether or not the requested amount is within the total service amount, and if the requested amount is within the total service amount, the money can be redeemed.

Thus, according to this embodiment, the sales status data can be stored for each customer, and the sales status data can be redeemed for cash if necessary, so by setting the service amount as the sales status data, It is possible to provide the same service without giving a discount at the time of purchase or issuing a cash voucher called a service voucher as in the conventional case. Therefore, the labor of the cashier is reduced, and the customer is freed from the troublesome work.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, the case where the service amount is calculated by multiplying the total amount of sales by a constant as the sales status data is shown, but the present invention is not limited to this. Of course, various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, a predetermined service amount (sales status data) can be automatically calculated according to each customer's purchase amount, and it can be cumulatively managed for each customer. In addition, it is possible to provide an electronic cash register which can realize the sufficient service system without requiring the cashier and the customer to perform complicated work because the accumulated service amount can be redeemed at the request of the customer.
