Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electronic cash registers (hereinafter referred to as ECRs), and particularly relates to improvements in the printing format of ECRs.

In the conventional ECR, registration data and payment data are printed in the same position on receipt paper and journal paper at the time of registration and payment.

Therefore, it is difficult to distinguish between registration data and payment data just by looking at the receipt or journal paper.

An object of the present invention is to make it possible to determine at a glance whether data is registered data or payment data without looking at the characters or symbols that define various data.

To summarize, this invention is such that registration data and payment data are printed at different positions on receipt paper or journal paper.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall block diagram of the ECH, which is the background of this invention. Reference numeral 1 is a keyboard, 2 is an arithmetic unit, 3 is a memory constituted by a RAM, 4 is a display, and 5 is a printer.

FIG. 2 shows the layout of the keyboard 1, in which 1a indicates a numeric keypad, 1b indicates a department key, 1c indicates a payment key, and 1d indicates a clear key.

FIG. 3 shows the layout of the memory 3, in which 31 is a memory area for each department, 32 is a print register, and 33 is a memory area for customer data management and total total management.

The departmental memory area 31 has a counter 31a for each department.
, totalizer 31b, and department symbols (DPI, D
P2, etc.) and product names (COFFEE, etc.) are stored in the alpha text 31c.

The print register 32 is an 18-digit register consisting of 8 bits per digit.

The memory area 33 has an itemizer (customer totalizer), 3
3a, total product counter 33b, totalizer 33c1, number register (X register) 33d, and payment symbol (CASH
).

Next, the operation will be explained with reference to the key operation example shown in FIG. 4 and the flowchart shown in FIG.

First, input the amount "100" using the numeric keypad 1a.

Accordingly, it is determined whether a numeric key is present, and after the first numerical value input clears the X register 33d, the numerical value 1-100J is stored in the X register.

Next, when the department key "DPI" is input, it is first determined whether the DPT key is present.

The alpha text 31c corresponding to the DPI is then read out and stored in the 13th to 18th digits of the print register 32.

If the product name corresponding to the department DPI is C0FFEE, then rcOFFEEJ is 13th to 13th by the ASCII code.
It will be stored in the 18th digit position.

Of course, alpha text) 31c is simply the department symbol “DPI
”, data 1-DPIJ is stored sequentially from the lower digit, and is stored in the 13th to 15th digit positions.

Next, the contents of the X register 33d are transferred to the fourth register of the print register 32.
It is stored in ~10 digit positions.

In this case, the value of the X register 33d is "100" and is stored in the fourth to sixth digit positions.

When the memory editing to the print register 32 is completed, the printer 5
The contents of the print register 32 are printed at the position corresponding to the storage digit position.

Then, the value ``100J'' of the X register 33d is added to the totalizer 31b corresponding to the department 1-DPIJ, the counter 31a is incremented by +1, and the value ``100J'' of the X register 33d is added to the itemizer 33a.

Similarly, if you enter the amount "200" from the numeric keypad 1a and enter the department key "DP2", the product name or department code of "DP2J"
The numbers 1-200J are stored and printed in the 4th to 10th digit positions.

When the payment key 1c (in this case, the cash key) is input at the end of registration, it is determined whether the cash key is present.

Then, the cache alpha text 33e in the memory area 33 is read out and stored in the 10th to 15th digit positions of the print register 32.

Specifically, the 10th to 13th digits are ASCII code “C
ASH” is memorized.

In addition, the value of the itemizer 33a is stored in the first register of the print register 32.
~ Stored in the 8th digit position.

The customer's current shopping total of 1-999J is itemizer 33
"999" is stored in the first to third digit positions of the print register 32.

When the memory editing to the print register 32 is completed, the printer 5
The contents of the print register 32 are printed at the position corresponding to the storage digit position.

Then, the value 1'- of the itemizer 33a is sent to the totalizer 33c.
999J is added, the counter 33b is incremented by +1, and the itemizer 33a is cleared.

FIG. 6a shows the conventional printing format, and FIG. 6b shows the printing format of the above embodiment.

According to this invention, since the printing position of the registration data and the printing position of the single payment data are printed differently, it is easy to distinguish between the registration data and the payment data, and the person who received the printed data can later print the shopping data. It has the effect of making it much easier to organize when organizing.

Claims (1)

[Scope of Claims] 1. A keyboard having a registration key such as a department key and a payment key such as a cash key, a print register that temporarily stores print data in response to the human input of keys on the keyboard, and a print register that stores print data in the print register. It identifies the printer to print and whether the input key is a registration key or a payment key, stores registration data in the first digit position of the print register in response to the input of the registration key, and stores the registration data in the first digit position of the print register when the payment key is An electronic cash register comprising a control means for storing payment data in a second digit position of the print register in response to input, and in which a registration data printing position and a payment data printing position are made different. .
