Description

[Detailed Description of the Invention] The present invention provides, for example, an electronic cash register (hereinafter referred to as
This invention relates to a recording device suitable for recording Z settlement data on a cassette tape in the ECR.

In the ECR, when recording Z settlement data on a cassette tape, conventionally, the number of digits in one record area on the magnetic tape was set according to the maximum number of digits of various totalizers in the ECR. For example, if the score on the departmental totalizer is 3 digits and the amount is 6 digits, the number of digits to be recorded must be 3 digits for the score and 6 digits for the amount. (See Figure 1) However, it is extremely rare for each totalizer to generate data with the maximum number of digits, so the number of digits in each record area is adjusted to match the maximum number of data digits in the corresponding totalizer. This has the problem of wasting the storage area on the tape and increasing the recording time.

This invention was made to solve the above problem, and its purpose is to shorten the recording time in this type of recording device, and to
The purpose is to make effective use of storage area and enable high-density data recording.

That is, the present invention is a recording device that sequentially records a plurality of numerical data each having an arbitrary number of digits in each record area of a recording medium; a memory for setting and storing a value to the number of digits with the highest frequency of occurrence; a data size determining means for comparing the size of the recorded numerical data with the digit limit value; If the number of digits exceeds the number of digits, the remaining numerical data exceeding the digit number limit is sequentially recorded in the next record area.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 2 shows the appearance of an ECR to which this invention is applied. As shown in the figure, a display 2, an operation panel 3, and a printer section 4 are provided on the front of the ECR 1, and a cassette deck 5 for recording the aforementioned Z payment data is connected to the ECR 1. There is.

As shown in FIG. 3, the operation panel 3 is provided with a key switch 6 for mode switching, a numeric keypad 7 for inputting various numerical data, and a department key 8 used for inputting various department data. In addition, as is well known, a clear key 9, a subtotal key 10, and a total key 11 are provided.

FIG. 4 is a block diagram showing the electrical system configuration of this ECR. As shown in the figure, this
The ECR is controlled by a microcomputer mainly composed of the CPU 12, and the magnetic tape recording control according to the present invention is performed by a program.
This is performed using predetermined areas within the RAM 14 and working RAM 13. working RAM
The contents are shown in Figure 5.

Next, in this ECR, the Z settlement data is
The operation when recording on a cassette tape is explained in the sixth section.
This will be explained with reference to the flowchart shown in the figure.

In this ECR, the sales price of a product is entered using the numeric keypad, sales are registered using department keys provided for each product category, and sales are made by five product categories. The input price and number of products are accumulated in a departmental totalizer (see FIG. 5) for each product.

The accumulated departmental totalizer data is recorded on a cassette tape, for example, at the time of Z settlement (a function to clear accumulated data) at the time of store closing, and then printed out as a sales report by a printer.

Therefore, an example of processing during data recording will be described below with reference to the flowchart of FIG.

First, when the mode switch is turned to Z settlement and the total key is pressed, the process advances from step (1) to step (2), and then steps (3) to (7) are repeatedly executed. That is, the department 1 totalizer of the departmental totalizers is loaded into the load area (WORK1), and the presence or absence of data in the score and amount areas is determined. If there is no data for both points and amount data, load the department 2 totalizer in the same way and make a determination. If there is no data in all the totalizers, the data is not recorded on the cassette tape and the process moves on to printing a sales report.

On the other hand, if data exists in any of the department 1 to 5 totalizers, step (8) is executed, the points of the loaded totalizer and the number of digits of the amount data are calculated, and each Stored in the number of digits area. (WORK2, WORK3).

Next, in the initial set processing, processing of the data recording method of the present invention is started using the preset recording data digit limit value.

For example, if the data for the department 1 totalizer is 200 points,
The amount is 20,000 yen, and the data from the department 2 total meter is the score.
It is assumed that the number of points is 1,000 and the amount is 1,000,000 yen, and the limit number of digits and limit data are preset as 3 digits for points (999 points) and 6 digits for amount (999,999 yen).

In this case, when the department 1 totalizer is loaded, the number of data digits, the score is 3 digits, and the amount is 5 digits, and both data are within the limit number of digits, so step (9) → step (10) → step (13) ) → Step (14) → Step (18) are executed sequentially, and the loaded data is transferred to the cassette recording data area 1 as it is.
Stored in (WORK4). Next, step (19) is executed, and the result of subtracting the recorded data from the load area (WORK1) is
Store in the load area. At this time, the same data is subtracted from the load area, so its contents become 0.

Next, steps (20) to (25) are executed, the data format is edited, the department code is loaded into the department code area (WORK5), and the recording data area 1 (WORK4) is loaded.
The points and amount data stored in are loaded into the recording data area 2 (WORK6) for each control digit, and then the data of WORK5 and WORK6 are transferred to the cassette tape as shown in the department 1 totalizer data section in Figure 7. is recorded. After recording is finished, the presence or absence of data in the load area (WORK1) is determined again, but at this time the area is 0, so
Totalizer data is loaded to the next department.

Since the department 2 totalizer has data of 4 digits for points and 7 digits for amount, both data exceed the limit digits, and the preset point control value data and amount are stored in recording data area 1 (WORK4). Limit value data is stored. This is step (9)
→ Step (10) → Step (11) → Step (12)
→ (15) is executed in sequence.

Furthermore, both the points and the amount of the restriction data to be recorded data are subtracted from the loaded department 2 totalizer data, and the results are stored in the load area. Therefore, the contents of (total of department 2) - (restriction data) are stored in the load area. Then, in the same way as when recording the department 1 total data, the department code and the point and amount restriction data that became the recorded data are recorded on the cassette tape as shown in the first part of the department 2 totalizer data section in Figure 7. Ru. After recording is completed, the presence or absence of data in the load area (WORK1) is determined, but at this time, the content of (Department 2 total) - (restriction data) is stored in the corresponding area, and the number of data digits is 1 point. , since the amount is 1 digit and both data are within the limit number of digits, the department code, points, and amount data are stored in the department 2 totalizer data section in Figure 7 by the limit number of digits, just like when recording the department 1 total data. As shown in the second part, the data is recorded onto a cassette tape.

Thus, according to the magnetic tape recording device shown in this embodiment, when the output data of each departmental totalizer is within the limited number of digits, the score data and amount data are each stored in one record area. However, if the score data and amount data each exceed the limit number of digits, the limit data is recorded as shown in the first part of the department 2 totalizer data section in Figure 7. The portion exceeding the limit data is recorded in the next record area, and finally the 7th record area is recorded.
Since the data shown in the second part of the section 2 totalizer data section in the figure will be recorded, the limit number of digits in the record area should be set, for example, to the number of digits that occurs most frequently. Therefore, the recording area on the tape can be used efficiently, and at the same time, since the tape is not run unnecessarily, the recording time can be shortened. Also, if data for one department is divided and recorded in two or more record areas in this way,
Since the department code corresponding to the data is sequentially attached to the beginning of each record area (7th
(see figure), then when reading magnetic tape,
The original data can be reliably reproduced based on this department code.

In this embodiment, the data of each totalizer is determined in size based on the limit digit, but it is also possible to divide the data based on the limit data. In this case, in the flowchart of FIG.
This can be realized by making steps (10), (12) and (14), which are the digit number determination routine, to determine limit data.

As is clear from the description of the embodiments above, the recording device according to the present invention is a recording device that sequentially records a plurality of numerical data each having an arbitrary number of digits in each record area of a recording medium; A memory that stores a digit limit value that limits the number of digits of data recorded on a medium by setting it to the number of digits that occurs most frequently.Data size determination that compares the size of recorded numerical data with the digit limit value. means; and oversize data processing means for sequentially recording the remaining numerical data exceeding the digit limit value in the next record area when the determination result of the data size determination means is larger than the limit number of digits. Because of this, it is possible to improve the recording density in this type of recording apparatus, prevent the recording area of the recording medium from being wasted, and shorten the recording time.
