Description

[Detailed Description of the Invention] This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an ECR in which item price data preset for each department is registered in a memory.

Recently, ECRs that are capable of so-called open registration, in which single-item price data entered using the numeric keys are registered, and so-called preset registration, in which single-item price data is preset in memory and then registered, have been put into practical use. It is provided.

FIG. 1 is a layout diagram of the ECH keyboard, which is the background of this invention and to which an embodiment of the invention is applied, and FIG. 2 is an explanation of key operations for open registration and preset registration, which is the background of this invention. This is a diagram for

An outline of conventional open registration and preset registration will be described with reference to FIGS. 1 and 2.

The ECH keyboard 10 includes a number key 11 for inputting single item price data manually during open registration, a clear (CL) key 12 for clearing the single item price data entered from the number key 11, A department key 13 and a calculation key 14 for instructing total calculation are provided.

The department key 13 includes DPI and DPIO keys, among which are DPI, DP3, and DP5.

DP7. The DP9 key is used as a department key when performing open registration, and DP2, DP4, DP6
゜DP8. DPIO is used as a department key when registering presets.

Further, individual item price data is preset in each storage area of the memory (not shown) corresponding to the DP2, 4, 6°, 8.10 keys.

Then, in order to open registration, operate the number key 11 to enter the single item price data r123j, and then enter the DP
When you operate the I key, the unit price data for department 1 l'-1
23j is registered.

Next, when the DP2 key is operated without operating the number key 11 for preset registration, the single item price data, for example r300J, preset in the memory storage area corresponding to DP2 is read out and registered.

Similarly, from the number key 11, the single item amount data “200
” and operates the DP3 key, the single item price data “200” for department code 3 is registered.

If you operate this DP3 key continuously, the previous position number key 11
The single item price data r200J input from is repeatedly registered (so-called repeat registration).

Finally, when the calculation key 14 is operated, the sum of the single item price data registered up to that point is calculated.

As described above, in the conventional ECH capable of open registration and preset registration, it was necessary to separately provide a department key for open registration and a department key for preset registration.

Therefore, if a large number of department codes are required, it is necessary to provide a correspondingly large number of department keys for open registration and department keys for preset registration, which increases the layout space of the keyboard 10. There must be.

Furthermore, there is a limit to increasing the layout space of the keyboard 10, and since many department keys cannot be provided, the number of items that can be preset is also limited.

SUMMARY OF THE INVENTION Therefore, the present invention provides an ECR preset registration method that uses both a department key for open registration and a department key for preset registration, and allows preset registration of single item price data for multiple items with fewer department keys. The main purpose is

To summarize, the present invention is provided with a counting means that counts the number of digits each time numerical information is input from the numeric key, and after a department code is input from the department key, the counting means Count the number of digits of numerical information input from
When the counted value reaches a predetermined value, the amount information preset in the second storage area of the storage means is stored in the first storage area of the storage means corresponding to the department code and the numerical information from the numeric keys. When the number of digits of numerical information entered from the numeric keys is stored and the number of digits input from the numeric keys is greater than or equal to a predetermined value before the department key is operated, the number of digits input from the numeric keys is input in response to the department code input from the department key.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIG. 1 and FIGS. 3 to 7.

In the embodiment shown here, a repeat key 15 for new repeat registration is provided in the keyboard layout diagram of FIG. 1.

Further, in this embodiment, when any of the two-digit numerical information 00 to 99 is input from the number key 11, preset registration is performed.

In the initial state, the X register 55. Y register 56
．． N counter 57. N flag 58. It is assumed that the DR flag 59 and the DP flag 60 are each reset.

First, open registration will be explained.

By operating the number key 11, the individual price data of the product, for example l'-123J, is input.

At this time, when the first numeric value "1" is input from the numeric key 11, the CPU 2 determines that the key was pressed manually and determines whether the input was from the numeric key 11 or not.

If the numeric key 11 is not the numeric key 11, it is determined whether it is the department key 13. If the numeric key 11 is the numeric key 11, the N flag 58 indicating that the numeric key 11 has been operated is set, and the DR flag 59 is set. Reset.

Then, the numerical information “■” input from the numeric key 11 is stored in the X register 55.

The CPU 2 sets the DP flag 60 when the department key 13 is operated.
Determine whether or not is set.

If it is set, the N counter 57 is incremented, but if it is reset, it waits until the next key is pressed.

In this way, the numerical information "1" as single item price data is
Input 23j sequentially from the numeric key 11 to the X register 55.
Store in.

Next, the DPI key included in the department key 13 is operated to enter the department code 1 manually.

In response, the CPU 2 determines that the department key 13 has been operated and sets the DP flag 60.

Further, the DR flag 59 is reset, and the department code 1 input from the department key 13 is stored in the Y register 56.

Then, it is determined whether the N flag 58 is set.

If it is not set, it returns to the initial state, and if it is set, the numeric key 11 stored in the X register 55
The numerical information r123J input from is cumulatively added to the area 40c and the itemizer 53.

Furthermore, the number of times in the area 40b is incremented by 1, and a DR flag 59 indicating that the registration has been completed is set.

Furthermore, N flag 58. DP flag 60°N counter 5
7 respectively, and the open registration operation is completed.

Next, the single item price data for coffee “250
The operation when registering "Yen" will be explained.

First, when the DP1 key is operated, the CPU 2 sets the DP flag 60 and stores the department code 1 input from the DPI key in the Y register 56.

Furthermore, it is determined that the 'N flag 58 is not set, and the process returns to the initial state.

Next, the operator inputs the numerical information "00" from the number key 11 to specify the price data of 250 yen per item of coffee preset in the area 400 of the memory 4.

In response, the CPU 2 determines that numerical information has been input from the numeric key 11 and sets the N flag 58.

Furthermore, the DR flag 59 is reset and the X register 55
The numerical information “00” is stored in .

Then, it is determined that the DP flag 60 is set, and the N counter 57 is incremented.

Further, it is determined whether the count value of the N counter 57 is 2 or not.

If the count value is 2, processing for preset registration is performed, but if the count value is not 2, it waits.

When the operator inputs the second digit O from the numeric key 11, the CPU 2 determines that the count value of the N counter 57 has become 2, and inputs the department code 1 stored in the Y register 56 and the department code 1 stored in the X register 55. Based on the numerical information "OO" stored in , the single item price data "250 yen" preset in the area 400 of the memory 4 is read out and stored in the X register 55.

Then, the single item price data "250 yen" stored in the X register 55 in the same manner as described above is added to the area 40c and the itemizer 53, and the number of times in the area 40b is increased by 1.

Furthermore, upon completion of registration of one product, the DR flag 59 is set, and the N flag 58. DP flag 60.
Each N counter 57 is reset to complete the preset registration.

Subsequently, when the operator operates the DPI key and inputs the numerical information "10" from the number key 11, the preset single item price data is registered in the area 410 (not shown) of the memory 4.

Also, operate the DP1 key and use the numeric key 11 to input the numerical information "
When the operator presses the key "99", the preset cola item price data "200 yen" is registered in the area 499.

Further, by operating the numeric key 11 to input numerical information "10" and operating the DPI key, single item price data of 10 yen is registered by open registration.

Next, when repeatedly registering the single item registration information with single item price data 10 and department code 1 through open registration,
Operate repeat key 15.

In response, the CPU 2 determines that the repeat key 15 has been operated, determines that the DR flag is set, and retrieves the single item price data stored in the X register 55.
10 yen" is added to the area 40c and the itemizer 53, and the number of times in the area 40b is increased by 1.

Furthermore, the DR flag 59 is set, and the N flag 58. DP
Flag 60. Reset the N counter 57.

Also, after operating the DPI key, enter numerical information "05" from the numeric key 11, and then press the repeat key 15.
When you operate , repeat registration is performed in the same way as the operation when repeat registration is performed after open registration as described above.

As described above, according to the present invention, when numeric information with a predetermined number of digits is input from the numeric keys after operating the department key, it is registered as a preset, and when numeric information with a predetermined number of digits or more is input, the numeric information with a predetermined number of digits or more When an input is made from a key and a department key is subsequently operated, open registration is performed, so there is no need to separately provide department keys for preset registration and open registration.

Therefore, there is no need to provide a large space for providing many keys on the keyboard of the ECR, and the ECR can therefore be miniaturized.

Furthermore, since single item price data for up to 100 items can be preset in one department code, the number of single item price data for products that can be preset registered can be increased.
