Abstract

PURPOSE:To improve operability at the time of displaying data without burdening an operator by performing the display control by discriminating specified optional data as a data group for fixed display and a data group for scroll display in the case of specifying the optional data as a display object. CONSTITUTION:When a series of optional data is specified as the data of the display object by a data specification means 2, a data extraction means 3 reads out a series of data which is specified from a data storage means 1 and extracts a 1st data group and a 2nd data group out of a series of data based on the discrimination data. A display control means 4 performs the fixed display of the 1st data group extracted by the means 3 on a display screen and the scroll display of the 2nd data group on the remaining area on the display screen. Therefore, in the case of specifying the optional data as the display object, the display control is performed by discriminating the data as the data group for the fixed display and the data group for scroll display. Thus, the operability at the time of displaying the data is improved without burdening the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data display device that performs scroll display.

[Summary of the Invention] The present invention stores a plurality of series of data consisting of at least a first data group and a second data group that are identified based on preset identification data in a data display device, A first data group and a second data group are extracted from a series of data specified as data to be displayed, the first data group is fixedly displayed on the display screen, and the second data group is fixedly displayed on the display screen.
The data group is scrolled and displayed in the remaining area on the display screen.

[Prior Art] Generally, in data display devices used in small electronic devices, etc., when a series of data (record data, etc.) cannot be displayed on the display screen at once, the series of data is displayed on the display screen. I try to scroll the display, but the heading part of the data also scrolls.

Therefore, conventionally, in order to display the heading part of the data in a non-moving, fixed manner on the display screen, an area of a size corresponding to the number of digits of the heading part is set as a fixed display area on the display screen. That's what I was doing. If you set a fixed display area on the display screen in this way, the data other than the heading part will be scrolled and displayed in the remaining area on the display screen, and the data in the heading part will always be displayed and output to the fixed display area. be done. As a result, it is possible to visually read the entire data by scrolling while checking the heading section.

[Invention tries to solve! WjlilHowever,
With conventional data display devices of this type, a fixed display area must be set on the display screen each time data to be displayed is specified and output, which requires extremely troublesome operations. .

The reason why the fixed display area is set each time in this way is considered to be that the size of the fixed display area is not constant depending on the number of digits of the heading part, etc.

If any data is specified as a display target, if it is possible to control the display by distinguishing between a data group for fixed display and a data group for scroll display, each time data to be displayed is specified. It is clear that there is no need to set a fixed display area for the data display, which reduces the burden on the operator and improves the operability when displaying data.

Of this invention! The problem is that when arbitrary data is designated as a display target, it is possible to control the display of the data by distinguishing between a data group for fixed display and a data group for scroll display.

[Means to solve the problem] The means of this invention are as follows.

The data storage means l (see the functional block diagram of FIG. 1, the same applies hereinafter) stores at least a first data group (for example, a heading section) that is identified based on preset identification data (for example, a delimiter code ","). This is a disk memory or the like that stores a plurality of series of data (for example, record data) consisting of a character string (character string) and a second data group. Note that the identification data may be the number of digits (data length) of the first data group, etc.

The data specifying means 2 is a key manual device or the like for specifying an arbitrary series of data from among a plurality of series of data stored in the data storage means 1 as data to be displayed.

The data extracting means 3 reads the series of data designated by the data specifying means 2 from the data storage means 1, and extracts a first data group and a second data group from the series of data based on the identification data. .

The display control means 4 causes the first data group extracted by the data extraction means 3 to be fixedly displayed on the display screen, and scrolls and displays the second data group in the remaining area on the display screen.

[Work] The operation of the means of this invention is as follows.

First, identification data for identifying the first data group and the second data group constituting the series of data is set in advance for each series of data in the data storage means l.
Assume that a delimiter code "," is set as identification data between the data group and the second pig group.

In this state, when an arbitrary series of data is designated by the data specifying means 2 as data to be displayed, the data extracting means 3 reads the designated series of data from the data storage means 1 and extracts the series of data based on the identification data. A first data group and a second data group are extracted from the data.

As a result, the display control means 4 causes the first data group extracted by the data extraction means 3 to be fixedly displayed on the display screen, and scroll-displays the second data group in the remaining area on the display screen.

Therefore, when arbitrary data is designated as a display target, display control can be performed to distinguish between data groups for fixed display and data groups for scroll display.

[Example] Hereinafter, one embodiment will be described with reference to FIGS. 2 to 6.

FIG. 2 is a block diagram showing the data processing device.

This data processing device has a main body CPU II as its core, and the main body CPU II controls various operations of this data processing device according to system programs, etc., and its peripheral devices include a key power section 12, a data file memory 13, and a printing section. 14 is connected to the main CPU II.

The key human power section 12 is a key human power device that inputs various data, commands, etc. The data input from the key human power section 12 is taken into the main body CPU II, processed, and then written to the data file memory 13.

The data file memory 13 stores a plurality of series of data consisting of one record or a plurality of records, and one series of data is structured as shown in FIG. 3, for example. The data shown in Figure 3 is data consisting of one record, and the number of digits of the data is arbitrary, and is variable length data that matches the number of digits of existing data, and the record delimiter code "( " is added, and the record data is divided into fixed display data (fixed data), scroll display data (scroll data), and non-display data. In other words, the fixed data and scroll data are divided into The space is separated by a preset data delimiter code "," and the scroll data and hidden data are also separated by the data delimiter code ",".Here, fixed data, scroll data, non-display data The display data is also variable length data consisting of an arbitrary number of digits, and the data delimiter code "," is set as identification data for identifying each data.

When arbitrary data is designated as a display target from the key human power section 12, the main body CPU II stores data in the data file memory 13.
The relevant data is read out from the computer, analyzed, and the results are stored in the work memory 15.

The work memory 15 has a view register, an f register, an S register, and a d register, and the following parameters are set in each register.

Statement register: This register stores the number of digits displayed on the liquid crystal display section 16. In this embodiment, the display screen has a one-line configuration and can display data for 10 digits. Therefore, "lO" is set in advance as the number of display digits on the liquid crystal display section 16 in the cross register.

f register: Stores the total number of digits of fixed data extracted from the 1 ref - 1 minute data read from the data file memory 13. In the example in Figure 3, the total number of digits of fixed data is "3" is set.

S register: It stores the value obtained by subtracting the value of the f register from the value of the cross register. It is a liquid crystal display! By subtracting the total number of digits of fixed data from the number of display digits in 6, the number of display digits of the remaining area (scroll display area) excluding the area where fixed data is displayed (fixed display area) on the display screen can be calculated. This value is set as the number of scroll display digits that can be displayed at one time in the scroll display area.

d register: Stores the total number of digits of the scroll data extracted from the 1 ref - 1 minute data read from the data file memory 13. In the example in Fig. 3, the total number of digits of the scroll data is "lo" is set.

Then, the main body CPU II reads the data read from the data file memory 13 as well as the values necessary for display control (display control information) from the work memory 15 and provides them to the display control section 17, and then displays them on the display control section 17. Give instructions.

The display control unit 17 controls display operations according to a display program stored in advance.
A liquid crystal display section 16, a display data memory 18, a work memory 19, and a scroll timer 20 are connected to.

The display data memory 18 has a fixed data memory 18-1 and a scroll data memory 18-2, and fixed data and scroll data transferred from the main CPU II are stored in the corresponding fixed data memory 18-1 in the display data memory 18. , is set in the scroll data memory 18-2.

The work memory 19 includes a scroll pointer P for specifying the reading start position of the scroll data memory 18-2.
In addition, it has a memory for holding display control information transferred from the main CPU II, and the work memory 19 stores the total number of digits F of fixed data as display control information.
, the number of scroll display digits S, and the number of scroll end digits ED are stored. Note that the total number of fixed data digits F is work memory 1.
The value of the f register in 5 and the number of scroll display digits S correspond to the value of the S register in the work memory 15, and the scroll end number of digits ED is control information for scroll display calculated in advance by the main CPU 11. The display control unit 17 then refers to the values in the work memory 19 and causes the data in the display data memory 18 to be displayed and output from the liquid crystal display unit 16. In this case, the display control unit 17 displays the fixed data on the display screen. Fixed display is performed, and scroll data is scrolled in the remaining area on the display screen.

Note that the scroll timer 20 is a timer for determining the time interval of scroll display.

Next, the operation of this embodiment will be explained with reference to FIGS. 4 to 6.

FIG. 4(A) shows the data structure of each record inputted and created in the data file memory 13 in advance, and includes fixed data,
This shows that the scroll data is not differentiated.

FIG. 4(B) shows the state after the above-mentioned records are classified into fixed data and scroll data, and by setting the data delimiter code "7" in each record, each record has the data delimiter code ",". Fixed data bordering on
It is divided into scroll data and hidden data. In addition,
In the figure, "Xx..." is fixed data, "00..."
"..." indicates scroll data, and "ΔΔ...J" indicates non-display data.

With the data delimiter code "," set in the data file memory 13 in this way, the main CPU
II executes operations according to the flowchart in FIG.

First, when arbitrary data is specified as a display target from the key input unit 12 (step AI), the main body CPU II reads out the corresponding data from the data file memory 13 (step A2).

Here, if the series of data specified to be displayed consists of a plurality of records, first the first record is read out for Lecote.

Then, among the roux codes read from the data file memory 13, data from the record delimiter code "(" to the first data delimiter code ",") is extracted as fixed data (step A3). This ff1fl is stored as f in the work memory 15.
Set in the register (step A4). It is now assumed that "3" is set in the f register as the total number of digits of the fixed data. Then, the total number of digits is f along with the fixed data.
It is read from the register and transferred to the display control unit 17 (step A5).

Next, the value of the f register is subtracted from the value of the statement register to obtain the number of scroll display digits and set in the S register of the work memory l5 (step A6).
If the number of display digits for 6 is "lO", r7J is set in the S register as the number of scroll display digits. Then, this scroll display digit number is transferred to the display cap 17 (step A7).

Furthermore, scroll data is extracted from the l record (step A8), the total number of digits of this scroll data is determined and set in the d register of the work memory 15 (step A9), now d is the total number of digits of the scroll data. It is assumed that rlOJ is set in the register. and,
The scroll data is transferred to the display control section 17 (step Al0).

Next, the process proceeds to step All, where the value of the S register is subtracted from the value of the d register, and it is checked whether the result (dS) is greater than "0". In other words, the number of remaining scroll data digits (undisplayed digits) is calculated by subtracting the number of scroll display digits from the total number of scroll data digits, and if this number of digits is greater than "0", proceed to step A12;
The digit a(d-5) is transferred to the display control unit 17 as the scroll end digit number, but if it is less than rQJ, the process advances to step A13 and “0” is transferred to the display control unit 17 as the scroll end digit number. .

Now, the number of scroll display digits in the S register is r7J, d
Since the total number of scroll digits in the register is "lO",
"3" is transferred as the scroll end number of digits.

Thereafter, the process proceeds to step AI4, where a display command is given to the display control unit 17, and it is checked whether all records of one display target data have been transferred to the display control unit 17 (step AI4).
15) Here, if the data to be displayed is made up of one record, the end of transfer is detected in step A15, but if it is made up of a plurality of records, the process returns to step AI. In this case, when the feed key is operated to specify the next record (step AI), the next record is read from the data file memory 13 (step A2), and the same process is executed thereafter.

On the other hand, when the display control section 17 receives a display command from the main body CPU II, it executes a display operation according to the flowchart of FIG.

Note that before the display control unit 17 starts executing the display operation according to the flowchart in FIG. 1
Various display control information transferred from the main body CPU 11 is written in 9.

In this state, when the display control unit 17 starts the display operation in response to a display command from the main CPU II, first,
The fixed data is displayed inverted on the display screen of the liquid crystal display section 16 for the total number of digits F in the work memory 19 (stay, paste, etc.).
).

Then, set the initial value "0" to the scroll pointer P (step B2), specify the reading start position of the scroll data memory 18-2 with the corner of this scroll pointer P, and start from this digit position by the number of scroll display digits S. The data is read and displayed (step B3). In this case, the area other than the fixed display area on the display screen becomes the scroll display area, and the scroll data is displayed in S digits from the first digit. Minutes (7 digits) are displayed and output.

Thereafter, the process proceeds to step B4, and it is checked whether the value of the scroll pointer P has reached the scroll end number ED in the work memory 19. If the value has not reached the scroll end number ED, the process proceeds to step B5, and the scroll pointer P After adding rlJ to and updating it, step B2
Return to In this case, the value of scroll pointer P is rlJ
, I, so this time S from the second digit of the scroll data
The digits are displayed and output.

This kind of scroll display operation is performed by the scroll timer 20.
repeated every time interval regulated by.

When the value of the scroll pointer P reaches the scroll end digit number ED (3 digits), the process returns to step 7'B2, the initial value is set to the scroll pointer P again, and the above-mentioned operation is repeated. As a result, the scroll data is are displayed again by scrolling sequentially from the beginning. therefore,
The same data is scrolled and displayed many times until other data is transferred from the main body CPU 11.

Note that in the above embodiment, the data delimiter code "," is set to distinguish between fixed data and scroll data, but for example, the number of digits (data length) of fixed data can be set at the beginning of a variable-length record. It may also be an additional record structure.

[Effects of the Invention] According to the present invention, when arbitrary data is specified as one display target, the display can be controlled by distinguishing between a data group for fixed display and a data group for scroll display among the data. It is not necessary to set a fixed display area each time data to be displayed is specified as in the conventional method, which reduces the burden on the operator and improves operability when displaying data.
