Abstract

PURPOSE:To ensure an array of keys which is suited to the user side, by changing the array of keys after storing it in a key position conversion table as well as to a fixed storage means of programs, etc. among storage means of an electronic cash register. CONSTITUTION:A fixed storage region and a variable region concerning programs are provided to a function decision table WT1 within an ROM16 of an electronic cash register. When the function and array of keys are changed, a mode switch 14 is set at a setting mode to apply an input to a buffer 15. With push of either one keys 10, the input is detected after encoding 11. Then the setting mode information is fed to an area (a) of a CPU12, and the CPU12 selects a set processing program of the ROM16. Then a key to be changed is pushed, and the CPU12 refers to a table T1 and designates an area to a conversion table 17 of an RAM17. When the designation is over with all conversion items, a key is pushed to transfer a table T2 of the RAM17 to the table T1 of the ROM16. In such a way, it is possible to form a key array suited to the user side.

This invention relates to an ECR in which the user can freely change the key layout according to each user's usage pattern.

<Prior Art> As shown in Figure 1, a conventional general cash register has a drawer 1 for storing cash generated in various transactions, and a keyboard equipped with numeric keys, function keys, etc. for inputting various transaction information. 2', a corresponding person key 3 for identifying which operator has processed the registration process, a mode switch 4 for instructing how to use the cash register @, and a display section 5 for displaying various registration data, etc. and a printer part 6 which prints and issues the details of each customer's transactions.

The keyboard 2 also includes numerical keys 7 for inputting quantity information etc. generated in each transaction, as shown in Figure 2.
It is generally comprised of a function key 8 that indicates what kind of information is input using the numerical keys 7, and a department key 9 that indicates which department the information belongs to.

By the way, the key layout of this keyboard 2 is usually fixed at the manufacturing stage by the manufacturer, so it may not match all users who purchase this ECR, and users who purchase it may not necessarily be able to use all the keys. Not necessarily. Furthermore, the keys used by each user are not necessarily placed in convenient positions.

<Purpose> In order to eliminate the above-mentioned conventional problems, the present invention provides an ECR that allows users to freely change the key layout of function keys that are not always used by each user. It was created with the purpose of

EXAMPLES Hereinafter, the present invention will be explained in detail by way of examples and with drawings.

FIG. 3 is a diagram showing a keyboard in which the key positions of the function keys 8 of the keyboard shown in FIG. 2 can be arbitrarily changed. , the journal paper feed key JOURNAL, and the total key TL for instructing the end of transaction registration are shown as fixed (unchangeable).

FIG. 4 is a block diagram showing the configuration of an ECR embodying the present invention.

In FIG. 4, input means 10 equipped with numeric keys, function keys, and department keys is connected to a key encoder (key signal generation means) 11 that generates predetermined key signals, and the key encoder 11 is a central processing unit that processes various information. It is connected to a processing unit (CPU) 12. The key encoder 11 is connected to a key force detection means 13 that detects each key operation signal, and the key force detection means 13 is connected to the EC.
Buffer means 15 to which a mode switch 14 defining the function of R is connected is connected. Still, the output of this buffer means 15 is connected to the CPTJI 2.

The above-mentioned CPU], 2 contains various programs including various processing programs, a key determination table T+ff, a fixed storage means (ROM) 1.6 in which ff is fixedly recorded in advance, various registered data, etc., and a key signal conversion table T2. A storage means (RAM) 17 for storing settings is connected to the A side 1, a display means 18 for displaying various information, and a receipt or journal ((printing means for printing) 9) connected to the display means 18 for displaying various information. The specific operation of the ECR of the present invention constructed as described above will be explained with reference to the flowcharts of FIGS. 5 and 6.

Incidentally, in the ECR implementing the present invention, a key determination tape /1/T1 as shown in the following table is stored in advance in the ROM 16 along with various processing programs. In this table, only the parts whose key positions can be changed are described, and the parts whose positions cannot be changed are actually stored in RON1 and RON6, but since they are common, their description is omitted here. ing.

First, the setting operation of the key position conversion checker will be explained with reference to the flowchart shown in FIG.

Before using the ECR, the operator sets a key position change table T2 in the RAM 17 if there is a change in the position of a function key.

Specifically, the operator first presses the mode switch 14 of the device.
is set to the setting mode and the setting mode information is stored in the buffer 15 (steps n1 to 03 in FIG. 5 and subsequent steps ni are simply written as ni). In such a state, when the operator presses any key of the input means 10, the key force detection means 13 is operated via the key encoder 11, and the setting mode information stored in the buffer 15 is changed to CP.
Input and store in area a of U 12 (14.I5)
. When the setting mode information is input and stored in this area a, the CPU I 2 selects a block diagram for setting processing stored in advance in the ROM 16 (I6). Next, the operator specifies the key position change program in the setting processing program and inputs the predetermined OB code at the input means 10.
Input to the CPUI 2 using the numeric keys and the ■ key (I7). Upon receiving this JOB code, the CPU I2 selects a key position change program (I8, I9).

When the key position change program is selected in this way, the operator first presses the key to be changed (for example, ■ key) on the input means 10, and the key signal (hard code) (for example, '8') is transmitted via the key encoder 11. ) to CPU12
(n 10゜nil, n13). Next, the operator presses the ■ key to indicate that the previously inputted key signal is the key to be changed. Upon receiving this instruction, the CPU 12 uses the key determination table 'F1' of the ROM1.6.
The key position (for example ■) corresponding to that key signal (hard code, 8°゛) is determined by referring to
A predetermined area (for example, ■) of the conversion table T2 of l7 is selected and designated (n14, n15). Next, the operator selects the key signal (hard code) that he wants to convert (for example, 3'' if he wants to change to ST) from the table, and inputs it from the input means 】0 to the CPU 】-2 via the key encoder 11, and ``・Press the ``゛ key and instruct M CPU 1.2 to set the change key signal (hard code ``3°'') in the previously specified area (for example ■) (n16.n
17).

In this way, the operator repeats the two operations for the key position that needs to be changed, and when all settings are completed,
Press the "L" key to complete the key layout change.
Instruct cPU12 (n I 8. n19).

- On the other hand, if there is no change in the L key layout, the operator selects the key position change program (after -7" T L
”Press the key (nlO, n20).

When this T L ” key is pressed, CPUI2 goes to RA
Sequentially select and designate areas ■ to 0 of table T2 of Ml7, and store them in areas ■ to 0 of tape/L/T of ROM16. The key signals (hard codes) are sequentially read out and stored and set in the corresponding key 67 area (021 to n24). In this way, if there is no need to change the key layout, the double T of ROM16,
The double T2 in the RAM 17 will be set to the standard key layout stored in memory.

Next, the input key signal determination operation will be explained with reference to the flowchart shown in FIG.

When the conversion data has been set in the table T2 of the RAM 17 as described above and the operator presses any key (for example, ■ key) on the input means 10 for registration processing etc., the key signal is transmitted to the encoder 11. It is converted into a specific hard code (for example, '8') and manually inputted to the CPU 12 (033 to n31).

CPU 2 that received this hard code is ROM16
The hard code stored in area C of file T1 is searched for, and the key position information (for example, ■) stored in area b corresponding to the hard code is read out (n84, n35). If the key read in this way is a key that can be changed, the CPU 12
Select and specify the key position (for example ■) of the double T2 of No. 7, extract the hard code set in the corresponding area (for example "3゛"), and store it in the ROM again] 617)
7- ) "T2 (7) Reads the function information (for example, ST) stored in the area corresponding to the hard code, and the CPU 2 executes the appropriate process for the function information ( n36°n39-n42).

On the other hand, if the read key position information is a key that cannot be changed, the CPU 12 inputs the functional information specified by the hard code recorded in area C of table T1.
(n37.n38).

In addition, it is easy to determine whether or not each key listed in L can be changed by setting a hook that indicates this in a specific area of table T1, and checking this hook. I won't go into details here because it's possible.

Change the ECR key to each user's usage form ■':r? This allows it to be used by Yuri's side by throwing it further.

<Multiple fruits>1'J, 1. ．． As described in Section 1, according to the present invention, the fixed phase old-F stage (Giri r finger determination table) is fixedly recorded, and the key position conversion table 6 is stored in the storage means, so that manual means can be performed. Because the user can set and use the system in various ways, depending on the usage pattern of the user, it is possible to provide an extremely practical ECR.
