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, so-called open registration, which registers the price of each item entered from the numeric keys, and so-called preset registration, which presets the price data of each item in memory and registers that data, are available. has been done.

Fig. 1 is a keyboard layout diagram of an ECR which forms the background of this invention and is applied as an embodiment of this invention, and Fig. 2 explains key operations for open registration and preset registration, which forms 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 keyboard 10 of the BCR includes a number key 11 for inputting single item price data manually during open registration, and 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 keys DP1 to DP10, among which are DPI, DP3, and DP5.

The DP7 and DP9 keys are used as department keys when performing open registration, and the DP2. DP4. DP6, DP8
．． DPlo is used as a department key when registering a preset.

Further, individual item price data is preset in each storage area of the memory (not shown) corresponding to the DP2, 4°, 6.8, and 10 keys.

Then, in order to open registration, operate the number key 11 to enter the single item price data "123j", then enter the DP
When you operate the 1 key, the unit price data for department 1 “123
15i is registered.

Next, when the DP2 key is operated without operating the numeric key 11 for preset registration, the single item price data preset in the memory storage area corresponding to DP2, such as ``300J'', 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 r200J6 (department code 3) is registered.

If you operate this DP3 key continuously, the previous position number key 11
Manually entered single item price data r200J6 (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 ECR capable of open registration and preset registration, it is 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, a correspondingly large number of department keys for open registration and department keys for preset registration must be individually provided, and the layout space of the keyboard 10 must be increased accordingly. There was a problem in that it had to be made wider.

Therefore, the department key for open registration and the department key for preset registration are used together, and when the department key 13 is operated immediately without entering the single item price data manually from the number key 11, preset registration is possible. There are ways to do this.

However, in this case, it is not possible to repeatedly register the single item price data inputted from the number key 11, so there is a problem that a repeat key must be provided individually.

Therefore, this invention is an EC that doubles as a department key for open registration and preset registration, and also enables repeat registration with simple operations without providing a repeat key.
The main purpose is to provide R.

To summarize this invention, when performing open registration, numerical information is entered manually from a key other than the predetermined keys of the numeric keys, and when a department code is manually entered from the department key, the numeric information from the numeric keys is used as amount information. The information is stored in a first storage area of a first storage means, and when a department code is repeatedly input from the same department key, the same amount information is repeatedly registered.

When registering a preset, operate a predetermined key (for example, 0) included in the numeric keys and enter a department code manually from the department key, and the department code will be stored in the second storage area of the first storage means. The corresponding preset amount information is registered in the first storage area of the first storage means.

At this time, if the same department key is operated repeatedly, the same preset amount information is repeatedly registered.

The present invention will be described in more detail below along with embodiments shown in the drawings.

FIG. 3 is a schematic block diagram of an ECR according to an embodiment of the present invention.

Key input signals from the keyboard 10 shown in FIG. 1 are given to a central processing unit (hereinafter referred to as CPU) 2 for performing calculation control.

The CPU 2 includes a read-only memory (not shown) configured with 70 grams for operating the ECR.

Random access memory (RA) is associated with this CPU2.
A memory 4 (described later in FIG. 4) is provided.

The product registration data and the like input to the CPU 2 are displayed by the display item 3 and printed by the printer 5.

FIG. 4 is a diagram schematically showing data stored in the memory 4.

In the figure, at '71, the memory 4 stores the D of the department key 13.
First storage means 4L42, 43 corresponding to each of the PI or DPIO keys, a number storage area 401 for each person in charge that stores the number of registration operations performed by an operator operating the ECR, and a storage area 401 for storing the number of registration operations performed by the operator operating the ECR, and a storage area 401 for storing the total amount registered by the operator. A total storage area 402 for each person in charge, an itemizer storage area 403 for storing the total amount for one customer, and a grand total storage area 404 for storing the total amount for all customers.
, a storage area 405 as an

The storage areas 41 to 43 include storage areas 411 to 431 for storing the department code, storage areas 412 to 432 for storing the number of registrations, storage areas 413 to 433 for storing the total amount, and storage areas 413 to 433 for storing the number of registrations, respectively. Storage areas 414 to 434 are provided in which monetary amount data is preset.

FIG. 5 is a flowchart for explaining the specific operation of an embodiment of the present invention, and FIG. 6 is a diagram showing an example of an operation when manually inputting single item registration information according to an embodiment of the present invention. It is.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIGS. 1, 3 to 6.

First, when entering, for example, the department code l and single item price data r123j manually through open registration, the key for the numerical value "1" included in the number keys 11 is first operated.

In response, the CPU 2 determines that there is a key force, and determines whether or not the key is pressed.

If it is determined that it is not the number key 11, it is determined whether it is the department key 13, but if it is determined that it is the number key 11, it is determined whether it is the first digit of the single item price data.

If it is not the first digit, the numerical information "1" entered manually from the numeric key 11 is stored in the X register 405, but if it is the first digit, the N flag 407 is set to logic "1".

Furthermore, since it is not a repeat registration, the DRN flag 409 is reset.

Furthermore, it is determined whether or not the operated number key 11 is a specific key, that is, the "0" key. If it is the "0" key, numerical information 0 is stored in the X register 405.

If it is not the rOJ key, it is determined that a key other than the specific key has been operated, and the NA flag 408 is set to logic "1".

Furthermore, the numerical information "1" manually entered from the number key 11 is stored in the X register 405, and the process returns to the initial state.

Next, in the same manner as described above, the second digit of the single item amount data, ``2'', is entered manually, but in the step of determining whether it is the 1st digit, it is determined that it is not the 1st digit, and the value is changed. Numerical information “2” is stored in the X register 405.

Similarly, input the third digit numerical information "3" to the X register 40.
Store in 5.

Next, when you operate the DPI key of department key 13, the CPU
2 determines whether the department key is 13, but if it is not the department key 13, processes other keys, and if it is determined that the department key is 13, it determines whether the N flag 407 is set. .

If not set, it is determined whether the input department code and the department code stored in the Y register 406 match.

If the N flag 407 is set, the department code "
1” is stored in the Y register 406.

Furthermore, it is determined whether the NA flag 408 is set.

If it is not set, the preset unit price of the department specified by the department code stored in the Y register 406 is stored in the X register 405, but if it is determined that the NA flag 408 is set, the above-mentioned The numerical information "123j" stored in the X register 405 from the key 11 is stored in the storage area 4 corresponding to the department code "1".
1 cumulatively to the total area 413, and the itemizer 403 adds and stores the numerical information r123J.

Furthermore, the DRN flag 409 is set when the first item price data and department code are registered.

Then, the N flag 407 and NA flag 408 are reset to return to the initial state.

When repeatedly registering the single item price data "123" manually entered from the numeric key 11 as explained above,
DPI of department key 13 without operating number key 11
Operate the keys.

In response, the CPU 2 determines that the department key 13 has been operated, determines that the N flag 407 is not set, and stores the department code "1" that was just entered manually and the Y register 40.
It is determined whether or not the department code stored in No. 6 matches the department code stored in No. 6.

If they do not match, it is an error and an error alarm is generated.

That is, if the DP2 key is operated this time even though the DP1 key was operated last time, the department code will be different and repeat registration will not occur.

If the department codes match, it is determined whether the DR flag 408 is set.

In other words, in order to repeat registration, press the previous position number key 1.
This is because the single item price information must have been input from 1, or the single item price data must have been input by preset registration.

If the DR flag 409 is not set, error processing is performed, and if it is set, the previous position number key 11 stored in the X register 405 is
The single item price data "123" manually entered from is added to the total area 413 and the itemizer 403 and stored.

Furthermore, the numerical value “1” is added to the number storage area 412.

Then, the set state of the DR flag 409 is maintained, and the N flag 407 and NA flag 408 are reset to return to the initial state.

Next, when presetting the single item price data preset in the storage area 414 of department code 1, for example "100", the rO
Operate the J key.

In response, CPTJ2 sets the N flag 407 and
The flag 409 is reset and numerical information “0” is stored in the X register 405.

Subsequently, when the DP1 key is operated, CPTJ2 stores the department code "1" in Y register 406.

Then, it is determined that the NA flag 408 is not set, and the preset unit price corresponding to the department code "1" is "
100'' and stores it in the X register 405.

Then, the single item price data is added to the storage area 413 and the itemizer 403 in the same manner as described above.

Furthermore, add 1 to the number of times / 1 cooking area 412, set the DR flag 409, and set the N flag 407 and NA flag 408.
Reset.

In this way, preset registration is completed.

When repeatedly registering the single item price data [100] preset-registered as described above, the DP1 key is operated again without operating the number key 11.

Thereby, repeat registration is performed in the same manner as the operation when repeating the single item price data inputted from the number key 11 described above.

At this time, if the DP2 key is operated when the DPI key should be operated, the department code "2" manually entered from the DP2 key and the Y register 406 It is determined that the department code stored in the department code does not match and handles the error.

At this time, the operator operates the clear key 12 and then operates the DP1 key again.

In addition, in the above embodiment, the 0 key included in the numeric keys is used as a specific key, but the present invention is not limited to this, and other keys such as the + key and 1 key may be provided and used as the specific key. Good too.

As described above, according to the present invention, it is possible to register single item price data preset in the memory by operating a specific key and a department key, and by operating a specific key and a department key. Single item price data input from the numeric keys can be registered using the keys.

Therefore, there is no need to provide a special key for preset registration, and the space required for the keyboard can be reduced.

Further, since repeat registration can be performed by simply operating the same department key after open registration and preset registration, there is no need to provide a dedicated key for repeat registration.
