Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales data processing apparatus and method capable of performing cash management and cash collection management reliably and safely.

[0002]

2. Description of the Related Art FIG. 10 shows a merchandise sales data processing apparatus including an electronic cash register 10 used as a terminal of a POS system or used as a stand-alone machine.

In such an electronic cash register 10,
Cashier uses data input means [scanner (not shown)
And the keyboard 20], the product registration control means operates to register the product in the sales file. The sales data is displayed on the display 21 (21SH for cashier and 21CT for customer) and printed on receipt paper.

[0004] When the product registration has been completed for all the products purchased by the customer and a closing operation is performed as a declaration of completion of one transaction, the accounting processing control means calculates the total amount and the like.
The cashier who receives the deposit from the customer who sees the total amount inputs the amount by key. The change amount is calculated. This change amount is also displayed on the display 21 together with the total amount and the like, and is printed on receipt paper by the printer 22 stored in the cash register main body 10B. Subsequently, the drawer 160 is automatically opened and a receipt is issued. Cashier
Take out the change and hand it to the customer along with the receipt. This ends the checkout.

[0005] Thus, product registration including complicated calculations, etc.
It is widely used in all stores and the like because it can quickly and accurately execute accounting processing and can obtain accurate and easy management decision data later.

The cash handling (cash management) in the merchandise registration and accounting means (commodity registration control means, accounting processing control means, etc.) is automatically opened in conjunction with the accounting processing, and can also be opened by key operation for currency exchange and the like. The main drawer (cabinet 161 and cash box 162) 160 is managed.

That is, at the time of opening the cash box 1
The change reserve is stored in the bill storage unit 163 and the coin storage unit 164 in the storage unit 62. The cashier temporarily holds the deposit (sales money) from the customer on the placement table 28, and stores the bill storage unit 16 in the automatically opened cash box 162.
3 and a coin equivalent to a change amount are taken out from the coin storage unit 164 and the amount is confirmed and handed over to the customer. After a while, the deposit (sales) is drawn up by cash type.
60 (163, 164). When the predetermined time or the stored amount reaches a certain amount, the cash (sales) in the drawer 160 is collected by a responsible person or the like. A change reserve (mainly coins) may be replenished on the way. In addition,
165 is a keyhole.

[0008]

However, as social diversification and internationalization, follow-up of in-store occupancy and reduction of human resource costs resulting from intensified competition, etc., become stronger, the status and characteristics of cashiers have increased. And the working hours of each person are diversifying. In other words, in addition to regular employees, there are also albiters, part-timers, and the like. In addition, outsiders are free to enter and exit.

However, the drawer 160 is of an open top type in order to improve business efficiency through facilitation of cash handling and is customarily made open so that the stored cash is completely visible in the open state. In addition, it can be opened not only by automatic opening linked to the accounting process but also by a relatively simple key operation on the keyboard.

[0010] Thus, cash exploitation by outsiders and accompanying injury cases are increasing and increasing. In addition, unfortunately, the automatically calculated sales amount does not match the cash stored in the drawer 160, and the deposit from the customer becomes a drawer 160 (163, 16).
4) It is said that there is a tendency to increase the chances of occurrence of a situation that is presumed to be caused by a person in the store such as not being stored in the store or losing cash during the collection operation. That is, there is an increasing number of occasions in which the reliability and security of cash management using the drawer 160 that is automatically opened and cash management thereafter are impaired.

To solve this problem, for example, it is conceivable to construct a merchandise registration and accounting means (10) capable of handling cash in a completely sealed state. In this case, the demand for miniaturization is satisfied and Do not incur significant cost.

An object of the present invention is to provide a small and low-cost commodity sales data processing apparatus and method capable of improving the reliability and safety of cash management and cash collection management for sales proceeds.

[0013]

A safe that can be inserted and can store the inserted cash in a sealed manner, a change amount storage control means for writing and storing the change amount calculated in the accounting process in the change storage medium, and a change amount read from the change storage medium And a change dispenser for dispensing cash equivalent to the above.

According to this invention, the cashier receiving the deposit from the customer at the time of the accounting process based on the product registration stores the deposit in a closed safe. This safe is difficult to remove unless a special operation is performed (for example, input of the password of the person in charge), and there is no fear that the sales (cash) is stolen unlike the conventional drawer.

Further, the change amount calculated during the accounting process is written and stored in the change storage medium by the change amount storage control means. The cashier does not need to handle the change (currency) while checking the change amount on the spot, and only has to hand the change storage medium to the customer. Work efficiency can be improved, and the risk of fraud can be minimized. The customer causes the change storage medium to read the change storage medium and receives the change amount.

Therefore, it is possible to greatly improve the reliability and security of cash management and cash collection management while achieving downsizing and cost reduction. In addition, the cashier's work efficiency can be improved, and a change storage medium can store a plurality of changes (changes), which is convenient for busy customers.

In addition to providing the same operation and effect as in the case of the invention, the change dispensing machine can easily check the total amount of change dispensed, so that cash management can be performed more reliably from this point.

Further, the invention of claim 4 is a commodity sales data processing method for performing commodity registration and accounting processing using commodity registration and accounting means, and stores a deposit received from a customer in the accounting processing in a sealed state. Store it in a safe that is difficult and difficult to remove without special operation, write the change amount calculated in the accounting process in a change storage medium without paying out cash, and change it with a separate change dispensing machine. This is a merchandise sales data processing method for paying out cash equivalent to a change amount read from a storage medium.

In this invention, the cashier stores the deposit received from the customer in a closed safe. The stored deposit is hard to see from the outside and the safe is difficult to remove without special operation. Therefore, there is no fear that the sales (cash) is stolen unlike the conventional drawer. In addition, the change amount is stored in the change storage medium without paying out cash corresponding to the change amount calculated in the accounting process. There is no need to store a large amount of change as a change reserve for each product registration and accounting means, and handling of cash is easy. Improve business efficiency.

The customer carries the change storage medium received from the cashier to a change dispensing machine separate from the merchandise registration and accounting means, and inserts the card. The change dispenser pays out cash corresponding to the change amount read from the change storage medium.

Therefore, the reliability and security of cash management and cash collection management can be greatly improved, and the size and cost of the product sales data processing device for implementing the method can be reduced. In addition, the cashier's work efficiency can be improved, and a change storage medium can store a plurality of changes (changes), which is convenient for busy customers.
