Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to electronic cash registers and, more particularly, to electronic cash registers that facilitate the use of novel check number files.

(Background of the Invention) Conventionally, electronic cash registers (hereinafter referred to as ECRs) used in restaurants and the like are known to have check number files. The check number file is a file that stores the customer's order information at the time of ordering, and is read out at the time of payment to immediately calculate the total amount. When a new check number file is to be used, the clerk inputs an arbitrary number and registers the check number file. However, in such an ECR, check number files that are already used by other clerks cannot be used, so when the number of clerks increases,
A situation often arises in which the number of a file currently in use overlaps with the number entered for new use, and a new check number cannot be registered as an error. In addition, it is not possible to know whether a certain check number can be used or not until the check number is input. As a result, each clerk has to enter multiple different check numbers over and over again until an unused check number file is found, which results in the hassle of registering new check number files and the lack of menus in the ECR. There was an inconvenience that the registration process was not smooth.

Furthermore, if a system is used that transmits the data registered in the ECR to the kitchen, the menu cannot be conveyed smoothly to the kitchen, resulting in customers having to wait, resulting in a lack of service. It was hot.

(Object of the Invention) An object of the present invention is to easily and smoothly register a new check number file in an ECR using the check number file system, in view of the above-mentioned problems with the conventional system.

(Structure and Effects of the Invention) In order to achieve the above object, the present invention provides an electronic cash register having a predetermined number of check number files and a memory for each clerk. Set the range of the file in each memory according to minimum data (start check #) and maximum data (end check #), and make it usable within the range of the minimum data and maximum data corresponding to each clerk, In addition, a means is provided to indicate that the device cannot be used outside this range.

According to this, the range of check number files that can be randomly accessed by a clerk is limited so that each clerk does not overlap, and usable check number files are allocated and displayed for each clerk. Based on the display, each clerk easily avoids the unusable range and immediately uses his or her own usable check number file.
Therefore, the check number file can be registered smoothly without erroneously inputting the check number of another clerk, and as a result, service to customers can be improved. In addition, the check number file can be used efficiently, and since the check number file to be used for each clerk is fixed, it can also be applied to checking sales, attendance, etc. for each clerk.

(Explanation of Examples) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the appearance of an ECR according to one embodiment of the present invention. In the figure, 1 is a keyboard, 2 is a printer, and 3 is a display. Fig. 2 is an enlarged view of the keyboard 1, where 101 is a mode changeover switch, 102 is a clerk key for distinguishing five clerks from A to E, and 103 is for department codes (or product names) from 1 to 35. A department key 104 for inputting is a key group consisting of numeric keys for inputting 0 to 9 and 00, a clear key CLR, and the like.

FIG. 3 is a block diagram showing the general configuration of the ECR, in which the central control unit (CPU) 4 operates the keyboard 1, It controls input/output devices such as the printer 2 and display 3, monitors operating procedures, transfers data, and performs various calculations. the above
The ROM stores a program that determines the operation of the CPU 4, and the RAM stores memory areas _M1 to E assigned by the clerk key 102.
It consists of _M5 , work area W, and flag area F. In each memory area _M1 to _M5 , totals and counters, start check #, and end check # of each clerk A to E are stored. WRN1 in work area W,
WRN2 is stored in memory, and data is stored from the replacement buffer at the time of setting, and becomes start check # and end check #, respectively. When check # is newly opened, data is stored in WRN1 from the buffer and becomes the data of the newly used check #. WRN2 receives the values of start check # and end check # stored in memory areas _M1 to _M5 of clerks A to E at any time, and checks the magnitude of the values stored in WRN1.

When WRCLK is set, the buffer data is entered as clerk #. Check # When opening a new store, Clark #A to E will be included along with Clark Key ON. FN becomes 1 when the numeric key 104 is pressed, and becomes 0 when any key other than the numeric key is pressed. Fa1 of flag area F becomes Fa1=1 when the key of numeric key 104 is pressed for the first time.
So, Fa2 becomes Fa2=1 when the key is pressed for the second time.
becomes.

Figure 4 shows the key sequence for setting start check # and end check #, starting check # → key → end check # → →
Operate in the order of Clerk # → New key.

FIG. 5 shows the key sequence when newly using Check#, which is operated in the order of the set clerk key → check# → new key.

Next, a data processing procedure of an electronic cash register according to an embodiment of the present invention will be explained with reference to flowcharts of key sequence operations shown in FIGS. 4 and 5.

Figure 6 shows the data processing procedure at the time of setting. First, set the mode changeover switch 101, and press the numeric key to store the numeric data in the numeric buffer and input 1 to FNK. be done.
Next, when the key is pressed, it is determined whether FN=1 or not, and since FN=1, proceed to the next step. However, Fa1 = 1 has not been stored in memory yet, so start check # is from the config buffer.
Stored in WRN1. Then, 1 is input into Fa1 and 0 is input into FN. Next, repeat the above operation again to determine Fa1=1, and this time
Since Fa1=1, end check # is stored from WRN2 from the numeric buffer. Then, 1 is input into Fa2, 0 is input into Fa1,
0 enters FN and returns to the start again.

Next, by pressing the new key, Fa2=1
If Fa2=1, proceed to the next step. Then, determine WRN1≦WRN2 and NO
If it is, it is displayed as an error, and if it is YES, the contents of the numeric buffer are stored in WRCLK.
Next, the clerk address is calculated from WRCL, and the address is updated in the start check # area. Then, the data of WRN1 is stored in start check #. Also, update the address in the end check # area and WRN2
data is stored in end check #. Then, the values of WRN1, WRN2, and WRCLK are sent to the print buffer for printing. Finally, 0 is input to FN and Fa2 to return to the start.

Next, FIG. 7 shows the data processing procedure when opening a new check#. First, set the mode changeover switch 101 to registration, and press the set clerk keys A to E to open this clerk #.
Stored in WRCLK. Next, when the numeric key is pressed down, this numeric key is input into the numeric buffer and 1 is entered into FN. Then, by pressing the new key, the check# data is saved from the buffer.
Stored in WRN1. Next, the clerk address is calculated from WRCLK, and the start check # is
Stored in WRN2. And in the next step
Comparing WRN1 and WRN2, WRN1<WRN2
If so, display it as an error, and if WRN1≧WRN2
If so, it means that you have selected a number greater than start check #, so the answer is YES and you proceed to the next step. Then end check #WRN2
and compare it with WRN1. and,
If WRN1>WRN2, this means that a number greater than end check # has been selected, and an error is displayed. If WRN1≦WRN2, this means that a number smaller than end check # has been selected, and the selected numeric key is within the appropriate range, so the check # file is newly opened. FIG. 7 is an example of setting printing.
