Description

[Detailed description of the invention] [Technical field of invention] This invention relates to electronic cash registers.

[Technical background of the invention and its problems]

Conventionally, with electronic cash registers, when the cashier enters his or her responsible person code during the registration mode, the cashier is signed on.After that, the drawer is opened every time a function key such as the registration lock key or the money exchange key is pressed, and the cashier returns to the seat. Some machines lock the drawer closed when you sign on when leaving the machine, but in inspection and payment mode, the drawer can be easily opened by operating a specific function key. Incidentally, switching between the registration, inspection, and payment modes is normally performed using a key switch. For this reason, anyone with a duplicate key could open the Citrowa by setting the mode to check/account mode and operating a specific function key, posing a problem with the security of money management within the drawer. From this, for example, in the inspection or payment mode, it is possible to open the drawer by operating a specific function key after performing the sign-on operation in the same way as in the registration mode, and then lock the drawer closed by the sign-on operation. However, there is a problem in that doing so makes the operation cumbersome.

[Purpose of the invention]

This invention was made to solve these problems, and provides an electronic cash register that can reliably manage money in the cash register in inspection and settlement modes, and also allows relatively easy opening of the drawer. The purpose is to

[Summary of the invention]

In this invention, the drawer is always locked in the closed state during the inspection or payment mode, and the drawer is opened by inputting a password from the - key and then inputting a specific function key.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

In Figure 1, 1 is the CPU (Central Processing Unit),
and CPU 1 via address path line 2, data path line 3, and control path line 4.
OM (Read Only Memo IJ) 5. RAM
(Random access memory) 6, key gate display control circuit 7, and I10 port 8 are connected. The keys connect a keyboard 9 and a display 10 to a single display control circuit 7. Said r,
A drawer opening device 12 for controlling the opening of the drawer 1, a printer drive device 14 for driving and controlling the printer 13, and a control switch 15 are connected to the key bead 9. Department key 9
2. A total key 93 as a registration key, an alternate key 94 as a specific function key, a person in charge key 95, etc. are provided.

The control switch 15 is a key switch that switches and sets the business mode to, for example, a registration mode, an inspection mode, a payment mode, and a setting mode.

The RAM 6 stores product sales data, for example, by department.
In addition to the totalizer that registers cumulative totals for each transaction and person in charge, as shown in Figure 2, there are a numeric counting area NCNT, a numeral data storage area NBUFF for storing numeric data, and a PIN code setting area AWORD. .

The CPU 1 reads program data from the ROM 5 in response to a mode designation signal from the control switch 15 and a key signal from the keypad 9, and controls each section based on the program data. Said CP
In UJ, when the control switch 15 specifies the registration mode, the person in charge code is input using the numeric key 9, and when the person in charge key 95 has the human power, the UJ enters the sign-on state and thereafter signs on again by pressing the same key. Department registration using the number key 9 and department key 92 until department registration is performed, receipt issuing using the total key 93 after department registration, and operation of the drawer opening device 12 are enabled. Further, the CPUJ always prohibits the operation of the drawer opening device 12 when the control switch 15 specifies the inspection mode and the payment mode. In this inspection/accounting mode, when the current total key 93 is pressed manually, the data cumulatively registered in the totalizer in the RAM 6 is sequentially read out and output to the printer drive device 14.
The printer 13 prints out a receipt and issues an inspection report and f# calculation report. Note that the contents of the totalizer will be cleared after the settlement report is issued.

In addition, in the inspection and payment mode, the opening control of the drawer 11 is particularly performed based on the flowchart shown in FIG.

In other words, when a 3-digit pin code is entered using the numeric key 91 and the replacement key 94 is pressed, the manually entered pin code is stored in the numeric data storage area NBUFF, and the contents of the storage area NBUFF and the pin code are stored. The entered password codes are compared in the setting area AWORD K7', and if they match, the drawer opening device 12 is operated. The number of digits input for the password using the numeral key 91 is sequentially stored in the numeral counting area NCNT.
” or more, an error will be processed. Also, the contents of the numeric data storage area NBUFF and the PIN code setting area A
Error processing is also performed when the contents of WORD do not match.

In such a configuration, in the inspection mode and N arithmetic mode, when the same code as the 3-digit PIN code preset in the PIN code setting area AWORD is entered using the numeric key 91 and the replacement key 94 is pressed manually. Only CPUI
At this point, the drawer opening device 12 is operated to open the drawer 11, and at other times the drawer 91 is locked closed.

Therefore, even if the user has the duplicate key for the control switch 15, there is no risk of the door being opened unless he or she knows the correct password code. Therefore, the money in the drawer 11 can be managed reliably in the inspection and settlement mode, and safety can be improved. Moreover, the drawer 1 is equipped with the number key 91 and the replacement key 94.
1 is opened, and after the drawer 11 is manually closed, it returns to the locked state again, so the operation for opening the drawer 11 is relatively simple.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to provide an electronic cash register that can reliably manage money in the drawer in the inspection and payment modes, and also allows the drawer to be opened relatively easily.
