[Detailed Description of the Invention] [Technical Field] The present invention relates to a data processing device that processes data in tabular format (hereinafter referred to as tabular data), and particularly to a small device that has a small display screen and can only partially display tabular data. This invention relates to an improvement of a data processing device.

<Prior Art> Conventionally, there has been a small data processing device in which the display capacity of the display unit is designed to be smaller than the storage capacity of the memory that stores tabular data. It was easy to become unable to clearly understand which part of the table data corresponded to.

<Object of the Invention> In view of the above circumstances, the present invention fixedly displays specific row data or specific column data in display data, and constantly checks which part of table data the currently displayed data corresponds to. It is an object of the present invention to provide a data processing device that makes it clear.

<Example> The present invention will be explained in detail below.

FIG. 1 shows the external appearance of a data processing device according to an embodiment of the present invention, and the entire device is designed to be small and portable.

In the figure, reference numeral 1 denotes a display section consisting of a liquid crystal display, and this display section 1 has a display capacity of 24 characters x 4 lines. A tabular display is performed on the display section 1 in units of a preset number of characters.

Below the display section 1, 26 character keys 2 having 26 alphabetical characters formed on their key tops are arranged. The character entry key 2 is switched to an alphabetic character or symbol entry key by an alphanumeric symbol shift key 3. Also, using the kana shift key 4, the character input key 2
It is also possible to replace it with a kana character input key.

Numerical keys 5 are provided on the right side of the display section 1.

This number key 5 is also switched to the input key for kana characters by the kana shift key 4. Also, 6 is the input key 17a.
, 7b, 7c, 7d are cursor keys, 8a, 8b, 8c
, 8d are calculation keys.

FIG. 2 is a block diagram of a data processing device according to an embodiment of the present invention.

In the figure, 101 is a display section, which displays data under the control of a control section 103 via a display drive section 102, 104 is a read-only memory ROM, and 105 is a random access memory.・Memory RAM
The former stores control commands for operating the control unit 103, and the latter stores display data, calculation results, or search conditions. 106 is a key device that connects the output terminal and input terminal from the CPUI O3.

FIG. 3 is a format of the table data stored in the RAM 105 of FIG. Data FFH at address head 000 (H represents hexadecimal).

The same applies hereafter) indicates the beginning of the table data, and data divisions are stored as OIH or OOH. ODH is 0 which means the line feed code of the table data. Each data is stored in ASCII code as shown in FIG. For example, the first data "Torihiki Sakiro" is C4H,D
8H, CBH.

B7H, BBH, B7H, 20F (, 20H, 20H are stored in the RAM 105.

When the data delimiter is OIH, this indicates that the subsequent data, that is, the data belonging to one cell of the table, is fixed data that cannot be rewritten as it is (hereinafter referred to as a locked state). Conversely, when the data delimiter is OOH, this indicates that the subsequent one cell data is non-fixed data (hereinafter referred to as unlocked state).

In the RAM 105, numbers or characters are stored based on input instruction key operations according to a predetermined table format, or numbers or characters are transferred from other data processing connected to the data processing device of this embodiment. Data is stored. The following description will be made assuming that the data shown in FIG. 3 has been input and stored.

The flowchart in FIG. 5 shows that the third
The process of executing the display shown in FIG. 7 from the data in the figure is shown.

In FIG. 5, X is an address pointer indicating a data RAM, and Y is a display buffer y (
n is a line counter of the display buffer, CO is an address pointer pointing to the display buffer, and CP is a pointer indicating the cursor position. Up to step A, 24 digits of data in the first row are stored from the ROM to the display buffer. Furthermore, when step B is reached, the beginning of the second line is found. Thereafter, by repeating the same process four times, 4 rows and 24 digits of data are stored in the display buffer, and then the contents of the display buffer are displayed to obtain the display shown in FIG. 7. In step C, it is checked whether the cell data located in Arful is in a locked state. That is, if the data at the address pointing to the cursor pointer is OIH, the lock symbol is turned on, and if not, the lock symbol is turned off (described later).
4 and a display drive device 102 for displaying the data (ASCII code) stored in the display buffer on the display device 101 as a character pattern.

The data processing device of this embodiment uses the following row fixed key (first
11) in the figure and the column fix key (11 in Figure 1),
Specific row or column data displayed on the display unit 1 can be fixed on the display. In addition, the row fixation is "5 engineering yen key [ZEl
Defined by key presses.

Column fixation is defined only by ■ key suppression.

When the press of the row fixing key is detected, a status flag inside the cPU is set. After that, cursor key 7a (
D key) is pressed, the buffer 202.203.2
The contents of 04 are rewritten by the process described later, and the contents of 9th
The display will be as shown in the figure, and the display on the top row will not change and will be in a fixed state.

Similarly, after column fixing key operation, cursor key 70 (El
key) is pressed, the buffer 201°202.20
3. The contents of (10) to (24) of 204 are rewritten, resulting in the display shown in FIG. 10, with the leftmost column being fixed.

As described above, the line fixing key is a control key that instructs to always display the first line being displayed, and an internal status flag is set by operating this line fixing key. Also, when the row fixing key is operated again, the status flag is reset. Therefore, each item name in the table can be displayed at all times on the first line, and each line below the first line is scrolled each time the cursor key is operated.

Specifically, when the cursor key 7a (mouth E key) is pressed, the address pointer After presetting to , by executing the process shown in FIG. 5, lines other than the first line (item line) of the display device are scrolled.

Further, when the cursor key 7b (@ key) is operated, the pointer X is preset to the first position of the preceding line, and the pointer Y is further preset to the second line, and then the process shown in FIG. 5 is executed.

In addition, the column fixed key is a control key that instructs that the data in the cell (one column of the table) at the beginning of each row is always displayed, and an internal status flag is set by operating this column fixed key. . Furthermore, when the column fixing key is operated again, the status flag is reset. Therefore, data (items) at the beginning of a line can be displayed at all times. Therefore, each time the cursor key is operated, cells other than the relevant item are scrolled and displayed in columns.

Specifically, as described above, the pointer By executing the process shown in the figure,
Scrolling is performed excluding the item Sen.

When the operation of the arithmetic control key 9 in FIG. 1 is detected, the buffer 204 in FIG. 8 is used exclusively for calculation.
As shown in FIG. 11, a calculator can be displayed on the lowest row.

Furthermore, when the operation of the search control key 10 shown in FIG. 1 is detected, by using the buffer 204 shown in FIG. 8 as a buffer for inputting search conditions, the search conditions are entered in the bottom line as shown in FIG. St=L/ is displayed, followed by the name of the search item entered manually.

The arithmetic control key 9 is used for the four arithmetic arithmetic functions, that is, the mode instruction for operating as the arithmetic function.The instruction of the arithmetic control key 9 causes the numeric key 5 and the arithmetic keys 8a, 8b', 8c,
An operation is performed in '8d, and the result can be moved to the aforementioned cell.

This calculation formula is stored in a separately provided calculation register (not shown), and the data is displayed at the bottom of the display (Figure 11).
By doing this, the address pointer Y of the display buffer is preset to the bottom row, and the arithmetic registers can be selected and sequentially transferred to the display screen as shown in FIG. 5 and displayed.

The search control key 10 is a mode instruction to be operated when searching for the above-mentioned item name. By operating this search control key 10, a search register equivalent to the arithmetic register is selected, and by a combination of letter keys and numeric keys, Enter the item name and save the data. At this time, in the same manner as described above, the data in the search register is transferred to the bottom row of the display device, thereby displaying as shown in FIG. 12.

Through this search, the device collates the data in the item name cell at the beginning of the row in the RAM, selects the row traveled, and presets its address pointer X.

Hereinafter, arbitrary data can be input by operating the input control keys for each cell of 0 display data to be displayed in the same way as the display in FIG.
, 7d, an arbitrary cell is selected, and data is inserted into and erased from the RAM 105 as shown in FIG. In such input, a problem occurs if, for example, unchanging data such as item names and unit prices are inadvertently modified.

Therefore, in this embodiment, a lock function is provided to prohibit data modification. This can be done by selecting any cell using the cursor keys and operating the lock key 12 to modify the delimiter code %Q[(//, or if the delimiter code is ^OIH#) to the unlock delimiter code %00H.Specifically, select the RAM cell corresponding to the cursor pointer CP, and if the lock key is operated, change the delimiter code to Th.
OOHII → Whisper OIH” or 10IH” → LS
Correct it as OOH// and store it. Each time the cursor key is operated, a delimiter code is read from the RAM, and the lock lamp 301 is turned on or off depending on the delimiter code.

When the kana shift key 4 (fl key or MΣ key) is pressed, katakana characters in the Aka Satana line or the Hamaya Rawa line are input, respectively.

In this embodiment, in order to prevent the device from becoming larger due to an increase in the number of keys due to the large number of types of kana characters compared to alphanumeric characters, the character keys are defined by overlapping the Akasatana line and the Hamayarawa line. Either one is selected depending on the number of operations of the kana shift key 4.

That is, as shown in FIG. 6, when the alphanumeric shift key (mode key) is operated, only the alphanumeric flag is turned on, and the lamp 302 defined by the alphanumeric key is lit. When the symbol shift key is operated, only the symbol flag is turned on, and the lamp 303 is lit as defined by the symbol key.

Further, when the kana shift key 4 is operated, if the kana flag A (aka satana input) is already turned on, the kana flag H (hamayarawa input) is turned on, and the kana character of hamayarawa is defined. When the kana shift key 4 is operated again, the flag is reversed. With these flags,
0 The lamp 304 or 305 is lit. As described above, when any character key is operated after the shift state is set, the character code is converted into a character code corresponding to each flag and output. Note that if the key is defined as only one character key, the character will be fixed regardless of the operation of the shift key.

Effects> As described above, according to the present invention, a data processing device that processes tabular data includes a display section that displays a portion of the tabular data, and an arbitrary line or line in the display data displayed on the display section. Display control means for fixing column data at a corner of a display screen, etc., and displaying table data other than the display data and excluding the row or column data in a place other than the display area of the fixed row or column data; With this feature, you can use the fixedly displayed row or column data as a clue to easily understand where the display data displayed on the display section is located in the entire table data, and display the table data in one place. It becomes possible to perform data processing on the entire table data even on a display screen that cannot be used.
