Abstract

PURPOSE:To effectively use a display row required for message display by providing a message display row decision means which decides the display row for the display of a message out of plural rows except for a cursor display row, and a message display means which displays the message whose display is requested on a decided message display row. CONSTITUTION:Assuming that a cursor K is located at a second digit on a third row, a cursor address at that time goes to (301). Therefore, the address (301) is stored in a cursor address register 52, and the number of rows at a position where the cursor K is displayed is calculated by using the cursor address. Such cursor row can be found by dividing the cursor address by size of line. In such a case, the cursor row shows (3), therefore, it is less than an offset value, and a value in which the offset value is added on the cursor row is set as a message display row, and (6) is stored in a message display row register 54. Thereby, it is possible to prevent the cursor K hidden behind by the message display.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a message display line control device for a document processing device in which message display lines can be variably set so that display lines can be effectively utilized. .

(Prior Art) A conventional document processing device includes a key fob with a large number of key switches arranged in an array, a device body that performs arithmetic processing on input data generated by operating the key fob, and an output device that outputs data input from the keyboard. Many devices include a device (for example, a printer device, a display device, etc.).

For example, an English word processor has a display device with multiple lines of display, a word remote that displays input data from the keyboard on the display device, and a word remote that allows you to create or edit documents, and a word processor that displays keys on the keyboard when pressed. Some printers have a typewriter motor that performs corresponding operations on the printer device each time a printer is used.

In order to reduce the weight and thickness of the display device, liquid crystal displays are increasingly being used.

Since large liquid crystal displays are expensive, inexpensive models use small liquid crystal displays to reduce the overall price of document processing devices.

(Problem to be Solved by the Invention) However, since conventional document processing devices have a fixed display line dedicated to message display on the bottom line of the display screen of the display device, in particular, the number of display lines of the display device is For document processing devices with a small amount of data, the area that can be used for the display line for displaying created documents (this is called "text area 3") is reduced, which may cause inconvenience to users when creating or editing documents. For example, in the case of a liquid crystal display that has a total of seven display lines, in addition to the message display line, the status display line and the scale display line are used as fixed dedicated display lines, so each If you allocate one line at a time, there will be only 4 remaining display lines, and these 4 display lines can only be used as a text area, and nearly half of the screen will be used for displaying things other than text.

The present invention has been made in view of the above circumstances, and in particular, the message display line is not always displayed like a status display or scale display, but a message is displayed only when necessary. The purpose of this paper is to make effective use of the display lines required to display messages.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a method for determining the display position of a cursor displayed on a display having a plurality of display lines based on the address of the display position of the cursor. cursor display line calculation means for determining whether the cursor display line is a display line; and a message for determining a display line for displaying a message from among a plurality of lines excluding the cursor display line, based on the determined cursor display line. The message display apparatus includes display line determining means, and message display means for displaying the message requested to be displayed on the determined message display line.

(Operation) The message display line is not a fixed line, but is variably set from a plurality of lines excluding the cursor display line based on the cursor display line.

(Effects of the Invention) As described above, the present invention determines the message display line from among the lines other than the cursor display line and displays the message without fixing the message display line.
There is no need to create a display line that only displays messages,
This can be used for other displays such as text display.

Therefore, even in a small display device with a small number of display lines, the exclusive range of the text area can be expanded and convenience can be improved.

Furthermore, by variably setting the message display line to avoid the cursor display line, the present invention prevents messages from being displayed overlapping the cursor display line during document creation or editing. There is no need to interfere with that.

(Embodiment) Hereinafter, an embodiment of a message display line control device for a document processing apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the external configuration of a document processing apparatus to which this embodiment is applied, and FIG. 2 is a block diagram showing the configuration of a control system of the apparatus. Note that this embodiment shows an example in which the present invention is applied to an English word processor.

As shown in FIG. 1, the main body frame 2 of the document processing device 1

The printing mechanism PM is a platen 20 that feeds printing paper.
, a carriage 21 that is moved in the left-right direction along this platen 20, a petal-shaped type foil 22 having a plurality of type characters at the tips of radially extending spokes, a printing cassette 23 that stores a printed text, and a printing cassette 23 that hits the printed text. This is an existing configuration equipped with a control solenoid 24 and the like.

In FIG. 2, the alarm mechanism AM shown in the same figure has a buzzer 32 and this hood 32 'l!'. It is composed of a drive circuit 33 that moves the motor once.

The control device C includes a CPU 36 and an input/output interface 34 . connected to the CPU 36 via a node 35 such as a data bus. It is composed of a ROM 40 and a RAN 150.

The program memory 41 of the ROM 40 contains the keyboard 3.
The printing mechanism PM corresponds to the coat data input from
In addition to a system control program for controlling the computer and display mechanism DM, various function control programs such as a message display control program are stored. Message memory 42
A large number of sets of various types of message information are stored in pairs with message numbers.

The RAM 50 is provided with various memory areas such as registers for temporary storage of calculation results of the CPLJ 36 and buffers for input data.
Message data display section (sofa 51, cursor address register 52, cursor line register 53,
A message display line register 54 and a message write address register 55 are provided. These bars
The purpose of use of the sofa and the register will be explained in conjunction with the explanation of the flow chart below.

FIG. 3 is a flowchart showing the contents of the message display process among the processes executed by the control device C. The present embodiment will be further explained below according to this flowchart. In the following explanation, each step in the flowchart will be explained using the symbols Sl, S2,...
The word ``Sute Tsubu'' is omitted.

The message display process in FIG. 3 is started when a message display request command is generated within the CPU 36, and
Set the message data on the sofa 51 for display/<. The message data to be set is the message requested in the routine that was being executed immediately before the message display process was started, and is the data read from the message data 42 in response to this request command. be.

Next, in step 82, it is calculated which line the cursor is displayed at at that time. During this calculation, the address of the cursor display position at that time (hereinafter referred to as cursor address, r C
(represented by ursorAD:) or - time is stored. The cursor address is a serial number representing the range from the start point to the end point of the screen of the display 30, and the number of lines cannot be directly known as it is.

Now, as shown in FIG.
The number of display lines of A is 10 lines from line 0 to line 9,
Number of display digits for each line (this is called line size, r L
ineSizer) has 100 digits from the 0th digit to the 99th digit (this numerical value is an example for ease of explanation, and is not limited to this numerical value). Therefore, the cursor address is 0 from the left on the 0th line.
~99, 1st line is 100~199 from the left, ... 9th
The rows are 900 to 999 from the left. Now, assuming that cursor K is located at the second digit of the third row, the cursor address (CursorAD) at this time is r301J. Therefore, the cursor address register 52 contains this r3.
01J will be stored.

Then, using this cursor address (CursorAD), the number of lines at the position where the cursor K is displayed (hereinafter referred to as the cursor line and expressed as "rCursorLine") is calculated. This cursor line (CursorLin
e) is obtained by dividing the cursor address (CjrsorAD) by the line size (LineSize). That is, in the case shown in FIG. 4, 301/10
It is determined from the calculation that 0=3 (the numbers below the decimal point are rounded down) and that the cursor K is on the third line. The cursor line (CursorLine) obtained by this calculation is stored in the cursor line register 53.

Next, at 83, the cursor line (CursorLine)
The value of roff is a predetermined value (this is called an offset value,
setJ).

This offset value is the number of lines that separates the message display line from the cursor line. In this example, this offset value (
Offset) is fixed at "3".

Note that this offset value is not limited to 3J, and may be any integer greater than or equal to 1 (however, it must be less than or equal to the number of lines displayed on the display 30). You may also set it.

This S3 is to determine whether there are four or more display lines above the cursor line, and in this embodiment, if there are four or more display lines above the cursor line, the cursor line The message is displayed three lines above the cursor line, and if there are no more than four display lines above the cursor line, the message is displayed three lines below the cursor line.

Here, since the 0th line is fixedly used as a scale line, a message cannot be displayed. Therefore, in this embodiment, if the number of displayed lines above the cursor line is three or less, the message is displayed three lines below the cursor line.

In the case of Figure 4, the cursor line (CursorLine)
"Since it is 3j, it is not a dog than the offset value, so
Next, processing 85 is executed. s5 is a process for determining a message display line (represented by I'MsgLine J), and the message display line (~IsgLine) is determined by adding an offset value (Offset) to the cursor line (CursorLine). The message display line (MsgLine) determined by this calculation is
The message is stored in the message display line register 54. In the case of FIG. 4, since 3+3=6, "6" is stored in the message display line register 54.

Next, in step 86, the start address for displaying the message (this is called the message write address, rWriteA
D) is calculated. This message write address is the first address of the message display line (the first
digit address). This message write address (WriteAD) is the message display line (MsgL).
It is determined by multiplying the line size (LineSize) by the line size (LineSize). This calculated value is stored in the message write address register 55. In the case of Figure 4, 6
X100=600, which matches the address in the 6th row, 1st digit.

Then, in step 87, the message data stored in the display buffer 51 is written (written) from the message write address at Sl, and after the display of the message data is completed, the message display process is completed. In the case of FIG. 4, a message is displayed on the sixth line, that is, three lines below the third line where cursor K is located. The hatched area in the figure is used as the message display line XrL.

A message once displayed is erased by processing in the main routine when a certain operation is performed or after a certain period of time has elapsed. However, the error message will continue to be displayed until the error is resolved.

Note that the message display is done in 1 of the message display entry IL.
A hammer may be used, or the message may be displayed only in a part of one line by using only the necessary number of digits in one line.

Next, as shown in FIG.
The case where cursor K is located at the 3rd column of the 4th row when O36 occurs will be explained.

In this case, the cursor address (CursorAD)
Since is r402J, the cursor line (CursorLine) calculated in S2 is 402/l 00=4. Therefore, in S3, the cursor line (CursorLin
e) is larger than the offset value (Offset) and S4
processing is executed.

In S4, the value obtained by subtracting the offset value (Offset) from the cursor line (CursorLine) is set as the message line (MsgLine). In the case of FIG. 5, the message line is 4-3=1. Therefore, in the next 86, l
X100=100 or message write address (Wri
teAD), and the first part with hatching in Figure 5 is
The line, that is, the line three lines above the fourth line where the cursor is located, becomes the message display line ML, and the next step 87 causes a message to be displayed on this message display line ML.

In this way, in this embodiment, the message is displayed on a line three lines away from the line where the cursor is located, so that the cursor K is not hidden by the message display. In addition, since the user's line of sight is directed toward the cursor K, by displaying the message near the line of sight, the amount of eye movement required when reading the message is greater than when the message is always displayed on the bottom line as in the past. It also has the effect of reducing eye fatigue.

It goes without saying that the present invention can be similarly applied to document processing apparatuses (electronic typewriters, Japanese word processors, etc.) other than the English word processor of the embodiment described above, and the type and dimensions of the display device 30 are also similar to those of the embodiment described above. It is not limited to this, and other types can be applied as well.
