2. Description of the Related Art Conventionally, in an office or the like, when a character string stored in a floppy disk or the like is digitized and confirmed, the character string stored in the floppy disk or the like is printed on a paper by a printer. It was common to print and visually confirm the character string printed on the paper.

However, in recent years, a so-called paperless method has been proposed from the viewpoint of forest protection, which is a raw material of paper, or the viewpoint of storage management of documents and the like, and it is electronically stored in a floppy disk or the like. It has been practiced to display a character string on a display device such as a CRT, a bit map display or a liquid crystal display without visually printing the character string, and visually confirm the character string on the display device.

In the character string display system for displaying the digitized character string on the display device, the character strings within the range displayable on the display device among all the character strings are sequentially displayed on the display device. It was something.

[0005]

However, in the conventional character string display system, the size of characters displayed becomes small due to the limitation of the screen size of the display device, or the screen flickers. To read a character string from the screen,
There is a problem that it is difficult to read for a long time.

Therefore, it has been proposed to increase the size of the characters displayed on the screen. However, if the characters are enlarged in this way, the number of characters that can be displayed on the screen at one time decreases, and the entire character string is reduced. It has been pointed out that it causes a new problem that it becomes difficult to read while understanding the meaning of.

Further, unlike the paper on which the character string is printed, the display device cannot read the character string while checking it with a writing instrument such as a pencil. You may lose sight of it,
Especially when you take your eyes off the screen,
There was also a problem that it was not possible to easily determine which part of the character string was read.

The present invention has been made in view of the above-mentioned various problems of the prior art, and an object of the present invention is to read an electronic character string on a screen. It is intended to provide a character string display system that makes it possible to instantly and accurately grasp a desired place such as a place where the user is currently reading even if he / she takes his eyes off the screen. Is.

(9) Character size This is data indicating the width and height of the character of the target portion W and the width and height of the character other than the target portion W. In the present embodiment, the character size of the target portion W is set to 16 points, and the character size other than the target portion W is set to 10 points.

(10) Screen Size This is data indicating the screen size of the display device 18 by the maximum number of lines of characters that can be displayed and the maximum number of digits that can be displayed in one line.

In addition, among the various data described above, with respect to the unit of attention U, the reading speed R, the number of noticed characters C, and the reading direction D, the keyboard 16 is provided with an operator for arbitrarily setting these values. The operator can appropriately set a desired value by operating the operator.

The keyboard 16 is turned on / off.
A power switch for turning off, a character string data designating operator for selectively reading the character string data stored in the magnetic disk 20 or the floppy disk 24 for each file, and a manual movement mode process or automatic operation described later. In the manual movement mode process, the attention portion moving operator for manually moving the attention portion W, the manual movement mode for manually moving the attention portion W, and the movement of the attention portion W automatically and manually according to time A mode designation operator for selectively designating the automatic / manual movement mode to be performed or the automatic movement mode to automatically move the target portion W according to time is arranged.

In the above configuration, first, a case will be described in which the manual movement mode (the mode in which the target portion W is moved only based on the operation of the keyboard 16) is selected by the mode designating operator.

When the power switch is turned on and the manual movement mode is selected by the mode designating operator, the manual movement mode processing routine shown in FIG. 2 is started. When this manual movement mode processing routine is activated, initial setting data of the character size is stored in various registers and flags of the RAM 14 by an initialization processing (not shown).

In this manual movement mode processing routine, first in step S202, the magnetic disk 20 is processed.
Alternatively, the character string data to be displayed on the display device 18 is designated from the floppy disk 24 and read into a predetermined area of the RAM 14. When the process of step S202 ends, the process proceeds to step S204.

In step S204, the attention unit U is designated by the operation of the operator of the keyboard 16 and R
It is set in a predetermined register of AM14.

At this time, a list of types of the target unit U is displayed on the screen of the display device 18 to prompt the operator to select the target unit U.

When the process of step S204 is completed, the process proceeds to step S206, and the character string forming the character string data read into the RAM 14 in step S202 is divided for each unit of attention U set in step S204.

FIG. 3 shows a sub-routine (character string division processing routine) showing the details of the processing in step S206.
However, in this character string division processing routine, in order to divide the character string for each target unit U, all the character strings of the character string data stored in the RAM 14 in step S202 and the target unit U From the type and the size of the screen of the display device 18 (the number of lines and the number of digits in one line when the entire screen is displayed, depending on the size of the character displaying the target portion W), attention is paid to all character strings of the character string data. While obtaining the number of units U, a process of arranging a pointer to the head of each unit of interest U is performed.

That is, in step S302, the maximum number of characters G in one screen when the entire screen is displayed according to the size of the character displaying the attention portion W is calculated from the size of the screen of the display device 18 by calculation. .

That is, the maximum screen character number G = the number of lines × the number of digits is calculated to obtain the maximum screen character number G.

When the processing of step S302 is completed, the process proceeds to step S304, and the maximum number M of characters of the target portion W is calculated and set.

That is, the maximum number of characters M = G / 2 (fractions are rounded down) is calculated to obtain the maximum number of characters M.

In this embodiment, the above-mentioned "M
= G / 2 ”is used, the expression“ M = G / 2 ”is an example, and“ M = G / 3 ”,
Other calculation formulas may be used as appropriate, such as “M = G / 4”.

When the process of step S304 is completed, the process proceeds to step S306, the entire character string of the character string data is divided for each target unit U, and the number of the target unit U in all the character strings of the character string data is obtained. A process of arranging a pointer to the head of each unit of interest U is performed.

If the number of characters in the unit of attention U exceeds the maximum number M of characters in any of the units of interest U, the unit of interest U is further divided into M units to form the unit of interest U. . That is, division is performed such that the M character from the beginning of the target unit U is the first division (target unit U) and the next M character is the second division (target unit U). At this time, the last division (unit of interest U)
May be less than M characters.

When the process of step S306 is completed, the character string division process routine is completed and the process returns to the manual movement mode process routine shown in FIG.

In the manual movement mode processing routine of FIG. 2, when step S206 is completed, step S208 is completed.
Then, the process proceeds to and the target unit U at the beginning of all the character strings of the character string data stored in the RAM 14 is set in the register of the RAM 14 as the target part W to be displayed first. Step S
When the process of 208 is completed, the process proceeds to step S210.

In step S210, the head of all the character strings of the character string data is set as the display start position V in the register of the RAM 14. When the process of step S210 ends, the process proceeds to step S212.

In step S212, a character string is displayed on the screen of the display device 18 based on the target portion W and the display start position V. At this time, in the character string displayed on the screen of the display device 18, the attention portion W is displayed with a character of 16-point size larger than other character string portions,
The character string other than the attention portion W is displayed as a character having a size of 10 points.

The display of the character string thus displayed is sequentially updated based on an instruction by the operator operating the keyboard 16.

That is, in step S214, whether an instruction to advance the reading position in the forward direction (instruction to move the attention portion W in the forward direction) has been issued or an instruction to advance the reading position in the backward direction (moves the attention portion W in the backward direction). Instruction)
Alternatively, it is determined whether an instruction to end the display on the display device 18 has been given.

If it is determined from the result of the determination in step S214 that the instruction to move the reading position in the forward direction has been given by the operation of the keyboard 16 (the instruction to move the target portion W in the forward direction), the process proceeds to step S216. The attention portion W is moved to the attention unit U immediately after.

When the process of step S216 is completed, the process proceeds to step S218, and the display of the character string on the display device 18 is updated based on the new target portion W and the display start position V.

FIG. 4 shows a sub-routine (screen display update processing routine) of the "update the display of the character string on the display device 18 in response to the movement of the target portion W" in step S218. However, in this screen display update processing routine, the display is updated from the new target portion W and the previous display start position V to the new target portion W according to the new display start position V.

That is, in step S402, the range of the character string to be displayed on the screen of the display device 18 is calculated and calculated from the new target portion W and the previous display start position V.

When the process of step S402 is completed, the process proceeds to step S404, and it is determined whether or not a part or all of the new target portion W is displayed on the screen of the display device 18.

If the determination result of step S404 is affirmative (Y), that is, if a part or all of the new target portion W is not displayed on the screen of the display device 18, step S404 is performed.
Proceeding to 406, the vertical center position of the new attention portion W is in the vertical direction of the screen of the display device 18 (in the case of horizontal writing. In the case of vertical writing, the “vertical direction” is set to “horizontal direction”. The display start position V is moved so as to coincide with the center position of the “direction”.

On the other hand, the determination result of step S406 is negative (N), that is, all the new attention parts W are displayed on the display device 18.
If it is displayed on the screen, the process proceeds to step S408 without any processing.

In step S408, the display device follows the new target portion W and the display start position V (if the new display start position V is set in step S406, it becomes the new display start position V). Update the display of the 18 character string.

When the processing of step S408 is completed, this screen display update processing routine is completed and the routine returns to the manual movement mode processing routine shown in FIG.
Return to 14.

Further, according to the determination result in step S214, an instruction to move the reading position in the reverse direction by operating the keyboard 16 (an instruction to move the target portion W in the reverse direction).
If it is determined that the process has been performed, the process proceeds to step S220, and the target portion W is moved to the immediately preceding target unit U.

When the process of step S220 is completed, the process proceeds to step S222, the screen display update process routine shown in FIG. 4 is executed as in the case of the forward direction, and a new target portion W and display start position V (step S406) are displayed. When a new display start position V is set in, the display of the character string on the display device 18 is updated based on the new display start position V.).

When the screen display updating process routine is completed, the process returns to the manual movement mode process routine shown in FIG. 2 and returns to step S214.

Furthermore, when it is determined from the determination result in step S214 that the operation of the keyboard 16 has instructed the end of the display on the display device 18, the processing of this manual movement mode processing routine is ended.

Next, an automatic / manual movement mode (the target portion W is automatically moved after a preset time has passed by the mode designating operator, and even if the time has not passed, the user operates the keyboard 16 A mode in which the portion W can be moved is selected) will be described.

When the power switch is turned on and the automatic / manual movement mode is selected by the mode designating operator, the automatic / manual movement mode processing routine shown in FIG. 5 is started. When this automatic / manual movement mode processing routine is activated, initialization processing (not shown) stores initial setting data of the reading direction D and character size in various registers and flags of the RAM 14.

In this automatic / manual movement mode processing routine, first, in step S502, the character string data to be displayed on the display device 18 is designated from the magnetic disk 20 or the floppy disk 24 and is read into a predetermined area of the RAM 14. When the process of step S502 is completed, the process proceeds to step S504.

In step S504, the attention unit U is designated by operating the operator of the keyboard 16 and R
It is set in a predetermined register of AM14.

At this time, a list of types of the target unit U is displayed on the screen of the display device 18 to prompt the operator to select the target unit U.

When the processing of step S504 is completed, the process proceeds to step S506, the character string division processing routine shown in FIG. 3 is executed in the same manner as the manual movement mode processing routine, and the step is performed for each target unit U set in step S504. The character string forming the character string data read into the RAM 14 in S502 is divided.

When the processing of the character string division processing routine is completed in step S506, the operation proceeds to step S508,
The attention unit U at the beginning of all the character strings of the character string data stored in the RAM 14 is set as the attention portion W to be displayed first as R.
Set in the register of AM14. When the process of step S508 ends, the process proceeds to step S510.

In step S510, the head of all the character strings of the character string data is set as the display start position V in the register of the RAM 14. When the process of step S510 ends, the process proceeds to step S512.

In step S512, the reading speed R is specified by operating the operator of the keyboard 16, and R
It is set in a predetermined register of AM14.

When the process of step S512 is completed, the process proceeds to step S514, and the reading end position P is set at the beginning of the character string.

When the process of step S514 is completed, the process proceeds to step S516, and a character string is displayed on the screen of the display device 18 based on the target portion W and the display start position V. At this time, in the character string displayed on the screen of the display device 18, the attention portion W is displayed with a character of 16-point size larger than other character string portions, and the character strings other than the attention portion W are not displayed. It is displayed in 10-point size text.

When the processing of step S516 is completed, the process proceeds to the processing of step S518 and subsequent steps, and a character string is displayed on the display device 18 based on the target portion W and the display start position V every predetermined time or in response to the operation of the keyboard 16 by the operator. Is displayed, and processing for sequentially updating the display is performed.

That is, first, in step S518, the current time is substituted for the reference time K, and the flow advances to step S520.

In step S520, the waiting time T is calculated from the target portion W, the reading end position P, and the reading speed R, and is set in the register of the RAM 14. This waiting time T is obtained by the following formula: waiting time T = number of characters from reading end position P to end of attention portion W / reading speed R 1.

When the process of step S520 is completed, the process proceeds to step S522, and the keyboard 16
It is determined whether or not an instruction to change the reading speed R, an instruction to move the target portion W, or an instruction to end the display on the display device 18 is issued by the operation.

If the result of the determination in step S522 is negative, that is, if the above instruction has not been issued for T seconds,
In step S524, the target portion W is moved to the immediately subsequent target unit, and the reading end position P is set as the beginning of the new target portion W.

When the process of step S524 is completed, the process proceeds to step S526, where the display of the character string on the display device 18 is updated by the screen display update process routine shown in FIG. 4 as in the manual movement mode process routine, and then step S518. Return to and repeat the subsequent processing.

On the other hand, when the result of the determination in step S522 is affirmative, that is, when the above instruction is given for T seconds,
It proceeds to step S528.

In step S528, it is determined whether the above instruction is an instruction to increase the reading speed R.

If the result of the determination in step S528 is affirmative, that is, if the above instruction is an instruction to increase the reading speed R, the process proceeds to step S530, and the reference time K, the current time Tc, and the previous reading end position P. Then, a new reading end position P is calculated from the previous reading speed R and the reading end position P is updated. That is, new reading end position P = previous reading end position P +
(Current time Tc−reference time K) × previous reading speed R is calculated to obtain a new reading end position P.

When the processing in step S530 is completed, the flow advances to step S532 to increase the reading speed R by 10%. That is, the new reading speed R = the previous reading speed R × 1.1 is calculated to obtain the new reading speed R.

In the present embodiment, the case where the reading speed R is increased by 10% as described above will be described. However, the rate of increasing the reading speed R is not limited to 10%, and may be appropriately changed. The reading rate R may be increased, and the rate of increasing the reading speed R may be arbitrarily changed.

When the process of step S532 ends, the process returns to step S518 and the subsequent processes are repeated.

On the other hand, if the result of the determination in step S528 is negative, that is, if the above instruction is not an instruction to increase the reading speed R, the process proceeds to step S534.

In step S534, it is determined whether or not the above instruction is an instruction to reduce the reading speed R.

If the determination result of step S534 is affirmative, that is, if the above instruction is an instruction to slow the reading speed R, the process proceeds to step S536, and the reference time K, the current time Tc, and the previous reading end position P are set. Then, a new reading end position P is calculated from the previous reading speed R and the reading end position P is updated. That is, new reading end position P = previous reading end position P +
(Current time Tc−reference time K) × previous reading speed R is calculated to obtain a new reading end position P.

When the process of step S536 is completed, the process proceeds to step S538, and the reading speed R is multiplied by 1 / 1.1. That is, the new reading speed R = the previous reading speed R / 1.1 is calculated to obtain the new reading speed R.

In this embodiment, the case where the reading speed R is slowed by 1 / 1.1 times as described above will be described, but the rate of slowing the reading speed R is limited to the above. Instead, it may be set to an appropriate ratio, and the ratio at which the reading speed R is slowed down may be arbitrarily changed.

When the process of step S538 ends, the process returns to step S518 and the subsequent processes are repeated.

On the other hand, if the result of the determination in step S534 is negative, that is, if the above instruction is not an instruction to slow down the reading speed R, the operation proceeds to step S540.

In step S540, it is determined whether or not the above instruction is an instruction to move the target portion W in the forward direction.

If the determination result of step S540 is affirmative, that is, if the above instruction is an instruction to move the target portion W in the forward direction, the process proceeds to step S542, and the target portion W is moved to the immediately following target unit, and The reading end position P is set as the beginning of a new target portion W.

When the process of step S542 is completed, the process proceeds to step S544, and the display of the character string on the display device 18 is updated by the screen display update process routine shown in FIG. 4 as in the manual movement mode process routine, and then step S518. Return to and repeat the subsequent processing.

On the other hand, if the determination result in step S540 is negative, that is, if the above instruction is not an instruction to move the target portion W in the forward direction, the process proceeds to step S546.

In step S546, it is determined whether the above instruction is an instruction to move the target portion W in the opposite direction.

If the result of the determination in step S546 is affirmative, that is, if the above instruction is an instruction to move the target portion W in the opposite direction, the process proceeds to step S548, and the target portion W is moved to the immediately preceding target unit, and The reading end position P is set as the beginning of a new target portion W.

When the process of step S548 is completed, the process proceeds to step S550, and the display of the character string on the display device 18 is updated by the screen display update process routine shown in FIG. 4 as in the manual movement mode process routine, and then step S518. Return to and repeat the subsequent processing.

On the other hand, the determination result of step S546 is negative, that is, the above instruction is not an instruction to change the reading speed R or an instruction to move the target portion W, but the display device 18
If the instruction is to end the display on
The manual movement mode processing routine ends.

Next, regarding the case where the automatic movement mode (a mode in which the predetermined number of characters are set as the target portion W and the target portion W is automatically moved character by character) is selected by the mode designating operator. explain.

Then, when the input number of noticed characters C exceeds “½” of the number of characters that can be displayed in the display mode of the noticed portion W on the screen of the display device 18, an error display is performed and another noticeable attention is given. Prompt to specify the number of characters C.

In this embodiment, an error occurs when the input attention character number C exceeds "1/2" of the number of characters that can be displayed in the display mode of the attention portion W on the screen of the display device 18. Although the display is performed, the display is not limited to this. For example, when the number of displayable characters exceeds "1/3" or when the number of displayable characters exceeds "1/4". The reference value at the time of error display may be appropriately set such that error display is performed on the screen, or the reference value may be arbitrarily changed.

When the process of step S804 is completed, the process proceeds to step S806, and C characters from the beginning of the character string of the character string data stored in the RAM 14 are set in the register of the RAM 14 as the attention portion W to be displayed first. .

At this time, in the character string displayed on the screen of the display device 18, the attention portion W is displayed as a character having a size of 16 points larger than the other character string portions, and the attention portion W
Character strings other than are displayed with a character size of 10 points.

When the process of step S814 is completed, the process proceeds to step S816, and the waiting time T is calculated from the number of noticed characters C and the reading speed R. That is, the waiting time T = (the number of noticed characters C / 2) / reading speed R is calculated to obtain the waiting time T.

The waiting time T set here is
(Number of characters of interest C / 2) This is the time required to read only the characters, that is, from the beginning of the character string to the center of the attention part W. Therefore, the reading end position P is always located at the center of the target portion W.

When the process of step S816 is completed, the process proceeds to step S818 to wait for the next process for the T seconds set in step S816.

The waiting time T set in step S816
When is elapsed, the process proceeds to step S820, and the waiting time T (the time required to read one character) is calculated from the reading speed R. That is, the waiting time T = 1 character / reading speed R is calculated.

When the process of step S820 is completed, the process proceeds to step S822, the current time is substituted for the reference time K, and the process proceeds to step S824.

In step S824, the instruction for changing the reading speed R or the instruction for setting the reading direction D by the operation of the keyboard 16 or the display device 1 for T seconds.
It is determined whether or not an instruction to end the display in 8 has been issued.

If the result of the determination in step S824 is negative, that is, if the above instruction has not been issued for T seconds,
In step S826, it is determined whether the reading direction D is the forward direction or the backward direction. Regarding the reading direction D, steps S850 and S854, which will be described later, will be described.
It can be changed in processing.

If the result of determination in step S826 is that the reading direction D is the forward direction, the flow proceeds to step S828, in which the attention start position is moved forward by one character and the attention end position is moved forward by one character for the target portion W. By moving in the respective directions, the target portion W is moved in the forward direction by one character.

When the process of step S828 is completed, the process proceeds to step S830, and the display of the character string on the display device 18 is updated by the screen display update process routine shown in FIG. 4 similarly to the manual movement mode process routine, and then step S822. Return to and repeat the subsequent processing.

On the other hand, if the result of determination in step S826 is that the reading direction D is in the reverse direction, the flow proceeds to step S832, in which the focus start position is moved backward by one character and the focus end position is moved by one character. By advancing in the minute reverse direction, the target portion W is moved in the reverse direction by one character.

When the process of step S832 is completed, the process proceeds to step S834, and the display of the character string on the display device 18 is updated by the screen display update process routine shown in FIG. 4 similarly to the manual movement mode process routine, and then step S822. Return to and repeat the subsequent processing.

If the result of the determination in step S824 is affirmative, that is, if the above instruction is given for T seconds,
It proceeds to step S836.

In step S836, it is determined whether the above instruction is an instruction to increase the reading speed R.

If the determination result of step S836 is affirmative, that is, if the above instruction is an instruction to increase the reading speed R, the process advances to step S838 to increase the reading speed R by 10%. That is, the new reading speed R = the previous reading speed R × 1.1 is calculated to obtain the new reading speed R.

In the present embodiment, the case where the reading speed R is increased by 10% as described above will be described. However, the rate of increasing the reading speed R is not limited to 10%, and may be appropriately changed. The reading rate R may be increased, and the rate of increasing the reading speed R may be arbitrarily changed.

When the process of step S838 ends, the process proceeds to step S840, the waiting time T (T = 1 character / R) is changed based on the new reading speed R, and then the process returns to step S822 to perform the subsequent processes. repeat.

On the other hand, if the result of the determination in step S836 is negative, that is, if the above instruction is not an instruction to increase the reading speed R, the process proceeds to step S842.

In step S842, it is determined whether the above instruction is an instruction to reduce the reading speed R.

If the result of the determination in step S842 is affirmative, that is, if the above instruction is an instruction to reduce the reading speed R, the flow advances to step S844 to set the reading speed R to 1/1.
Double. That is, the new reading speed R = the previous reading speed R / 1.1 is calculated to obtain the new reading speed R.

In this embodiment, the case where the reading speed R is slowed by 1 / 1.1 times as described above will be described, but the rate of slowing the reading speed R is limited to the above. Instead, it may be set to an appropriate ratio, and the ratio at which the reading speed R is slowed down may be arbitrarily changed.

When the process of step S844 is completed, the process proceeds to step S846, the waiting time T (T = 1 character / R) is changed based on the new reading speed R, and then the process returns to step S822 to repeat the subsequent processes. .

On the other hand, if the result of the determination in step S842 is negative, that is, if the above instruction is not an instruction to slow down the reading speed R, the flow advances to step S848.

In step S848, it is determined whether the above instruction is an instruction to set the reading direction D as the forward direction.

If the result of the determination in step S848 is affirmative, that is, if the above-mentioned instruction is an instruction to set the reading direction D to the forward direction, the process proceeds to step S850, and the reading direction D is set to the forward direction (D = 1). After that, the process returns to step S822 and the subsequent processes are repeated.

On the other hand, if the result of the determination in step S848 is negative, that is, if the above instruction is not an instruction to set the reading direction D to the forward direction, the process proceeds to step S852.

In step S852, it is determined whether the above instruction is an instruction to reverse the reading direction.

If the result of the determination in step S852 is affirmative, that is, if the above instruction is an instruction to reverse the reading direction, the flow advances to step S854 to set the reading direction D to the reverse direction (D = -1). After that, the process returns to step S822 and the subsequent processes are repeated.

On the other hand, the determination result of step S852 is negative, that is, the above instruction is not an instruction to change the reading speed R or an instruction to set the reading direction D, but the display device 18
If it is an instruction to end the display on, the automatic movement mode processing routine is ended.

Next, referring to FIGS. 11 to 31,
An operation example of the character string display system according to the present invention will be described.
In the following description, a character string having the contents shown in FIG. 11 will be described as an example of the character string displayed by the character string data read from the magnetic disk 20 or the floppy disk 24.

Each sentence of the character string shown in FIG. 11 is as shown in FIG.
The display device 1 is composed of the number of characters as shown in
The screen size of 8 and the size of the characters displayed on the screen are as follows:
It is said that "4 digits, height: 10 lines of characters for 8 lines", and the size of the characters is initially set to "attention part W: 16 points, other than attention part W: 10 points". To do.

It should be noted that the number of digits and the number of lines when displaying the entire screen in 16-point character is 15 digits, 6
Be a line.

[Manual Movement Mode Processing] This manual movement mode processing is controlled by the above-mentioned manual movement mode processing routine (FIG. 2).

In this manual movement mode process, when the character string data is selected and read into the RAM 14 after the power is turned on (step S202), a list of the target units U is displayed on the screen of the display device 18 as shown in FIG. Is displayed, the operator is prompted to select the attention unit U, and the attention unit U is set (step S204).

As the attention unit U, "character", "line",
"Word", "section", "sentence" and "paragraph" can be selected. Here, "character", "line", "word", "section", "sentence" and "paragraph" are defined as follows.

“Character” is each character that constitutes a character string.

A "line" is a line containing one or more characters.

The "word" is a portion which is divided into appropriate word divisions by referring to a dictionary stored in advance on the magnetic disk 20.

If the character string is Japanese, the character type (Hiragana, Katakana, Kanji, Roman, punctuation, etc.)
You may make it divide in all the places which change. In this case, for example, the character string "in the case of bank transfer" is "bank transfer", "ri", "transfer",
It will be divided into seven parts: "Mino", "case", "to", and ",".

In the case of English, it may be separated by a space or a line feed position.

The “bunsetsu” is each part which is divided by using a well-known syntactic analysis process or by separating when the character type changes to kanji, katakana, or romaji.

When the character type is delimited at the place where it changes from hiragana to kanji, katakana or romaji, for example, the character string "in the case of bank transfer" is "bank transfer" or "bank transfer". In Case of,"
Will be separated.

In the case of English, it may be separated by a semicolon, a comma or a period.

In the case of Japanese, a "sentence" is a punctuation mark (.).
Each part is separated by. Also, in the case of English, it may be separated by a period.

In the case of Japanese, a "paragraph" is a portion separated by a blank at the beginning of the line or a blank line. Also, in the case of English, as in the case of Japanese, it may be separated by a space at the beginning of the line or a blank line.

In the following processing, a case will be described in which a "sentence" is selected from the above noted attention units.

When a "sentence" is selected as the unit of attention U by operating a predetermined operator of the keyboard 16 (step S204), the entire character string shown in FIG. 11 is divided for each "sentence" as the unit of attention U. (Step S206).

At this time, the size of the screen of the display device 18 is “15 digits × 6 lines = 90 characters”. Then, the maximum number of characters of the attention portion is "90 characters / 2 = 45 characters".

The character string shown in FIG. 11 has a total of 367 characters (including punctuation marks, excluding blank spaces in paragraphs), and is composed of 12 sentences. Then, as shown in FIG.
The fourth sentence (65 characters) and the sixth sentence (53 characters) exceed "45 characters", and thus are divided into a plurality of parts.

That is, the fourth sentence (65 characters) is "45 characters".
Is divided into "20 characters" and the sixth sentence (53 characters) is divided into "45 characters" and "8 characters".

In the following description, each part formed by the above division will be referred to as a "division part".

Then, the first divided portion of the character string divided as described above, that is, the first sentence is set as the target portion W (step S208), and the display start position V is set as the beginning of the character string (step S210). .

Thus, as shown in FIG. 14, only the attention portion W located at the beginning of the character string is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S212). .

In the display state shown in FIG. 14, if an instruction to move the attention portion W in the forward direction is made by operating the keyboard 16, the attention portion W is moved to the second sentence and shown in FIG. As described above, only the second sentence of interest W is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S21).

Furthermore, in the display state shown in FIG.
If an instruction to move the target portion W in the forward direction is made by operating the keyboard 16, the target portion W is moved to the third sentence, and as shown in FIG. Only 16 characters are displayed at 16 points, and characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S214 → step S216 → step S218).

Further, in the display state shown in FIG. 16, if an instruction to move the target portion W in the opposite direction is made by operating the keyboard 16, the target portion W is moved to the second sentence, and the operation shown in FIG. As shown in FIG. 10, only the second sentence of interest W is displayed at 16 points, and characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S).
214 → step S220 → step S222).

As described above, only the desired portion of interest,
Since it can be displayed in a larger character than other characters, it is easy to read, and even if you take your eyes off the screen of the display device 18, it is possible to easily identify the part currently being read. become able to.

[Automatic / Manual Movement Mode Processing]
The manual movement mode process is controlled by the above-described automatic / manual movement mode process routine.

In the automatic / manual movement mode process, after the power is turned on, the character string data is selected and the RAM is selected.
When it is read by 14 (step S502), a list of the attention unit U is displayed on the screen of the display device 18 to prompt the selection of the attention unit U, and the attention unit U is set (step S5).
04). As described in the above [manual movement mode process], as the attention unit, "character", "line", "word", "section", "sentence" and "paragraph" can be selected, A case where a "sentence" is selected from the above-mentioned attention units will be described.

When a "sentence" is selected as a target unit by operating a predetermined operator of the keyboard 16, the entire character string shown in FIG. 11 becomes the target unit, as in the above-mentioned "manual movement mode process". It is divided for each "sentence" (step S506).

Then, the first division part (20 characters) of the character string divided as described above, that is, the first sentence, is the target portion W.
(Step S508), and the display start position V is set to the beginning of the character string (step S510).

As the value of the reading speed R, "10 characters /
It is assumed that “second” is input by operating a predetermined operator of the keyboard 16 (step S512).

In this way, the reading end position P is set to the head of the character string (step S514), and as shown in FIG. 14, only the attention portion W located at the head of the character string is displayed at 16 points, and the screen of the display device 18 is displayed. Characters that can be entered are displayed at 10 points (step S516).

Then, the present time is set to the reference time K (step S518), and the waiting time T is set to "T = 20/1.
0 = 2.0 (seconds) "(step S520), and T
It waits for (= 2.0) seconds (step S522), moves the target portion W to the second sentence (15 characters), and
As shown in FIG. 5, only the second portion of interest W is 16
Characters that are displayed in points and that can be displayed on the screen of the display device 18 are displayed in 10 points (step S524 → step S526).

As shown in FIG. 6, only the attention part W, which is the third sentence, is 16
Characters that are displayed in points and that can be displayed on the screen of the display device 18 are displayed in 10 points (step S524 → step S526).

Then, the present time is set to the reference time K (step S518), and the waiting time T is set to "T = 28/1.
0 = 2.8 (seconds) "(step S520), and T
It waits for (= 2.8) seconds (step S522), moves the attention part W to the division part (45 characters) at the beginning of the fourth sentence, and as shown in FIG. Only the target portion W, which is a divided part of, is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S524 → step S526).

Then, the present time is set to the reference time K (step S518), and the waiting time T is set to "T = 45/1.
0 = 4.5 (seconds) "(step S520), and T
After waiting for (= 4.5) seconds (step S522), the target portion W is moved to the division portion (20 characters) of the second portion of the fourth sentence, and the fourth sentence is moved to the fourth sentence as shown in FIG. Only the target portion W, which is a divided portion of the second portion, is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S524 → step S52).
6).

Then, the current time is set to the reference time K (step S518), and the waiting time T is set to "T = 20/1.
0 = 2.0 (seconds) "(step S520), and T
It waits for (= 2.0) seconds (step S522), moves the attention portion W to the fifth sentence (17 characters), and
As shown in FIG. 9, only the fifth part, the attention part W, is 16
Characters that are displayed in points and that can be displayed on the screen of the display device 18 are displayed in 10 points (step S524 → step S526).

Then, the current time is set to the reference time K (step S518), and 1.3 seconds after the reference time K, an instruction to move the target portion W in the forward direction is given (step S522 → step S528 → step). S534 → step S540). At this time, "1.3 <17/10"
Therefore, at the time when the instruction to move the target portion W in the forward direction is given, the fifth sentence is the target portion W.

Then, when an instruction to move the target portion W in the forward direction is given (step S540), the target portion W is immediately moved to the first division part (45 characters) of the sixth sentence (step S542). , The only divided part W at the beginning of the sixth sentence is displayed at 16 points, and the display device 18
A process for displaying characters that can be displayed on the screen of 10 points with 10 points is performed (step S544).

However, in the state as shown in FIG.
When the attention part W, which is the beginning division part of the th sentence, is displayed at 16 points, a part of the attention part W (the beginning division part of the sixth sentence) cannot be displayed on the screen (see FIG. 20). The display start position V is changed so that the center of the first divided portion of the sixth sentence is the center of the screen of the display device 18 (step S54).
4).

After the above processing is performed, as shown in FIG. 21, only the attention portion W, which is the first divided portion of the sixth sentence, is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed. Display with 10 points.

Then, the current time is set to the reference time K (step S518), and 3.5 seconds after the reference time K, an instruction to move the target portion W in the reverse direction is given (step S522 → step S528 → step). S534 → step S540 → step S546). At this time,
Since “3.5 <45/10”, at the time when the instruction to move the target portion W in the reverse direction is given, the first divided portion of the sixth sentence is the target portion W.

Then, when an instruction is issued to move the target portion W in the opposite direction (step S546), the target portion W is immediately moved to the fifth sentence (17 characters) (step S5).
48), as shown in FIG. 22, only the 5th sentence of interest W is displayed at 16 points, and the characters that can be displayed on the screen of the display device 18 are displayed at 10 points (step S).
550).

Then, the current time is set to the reference time K (step S518), and 0.8 seconds after the reference time K, an instruction to move the target portion W in the reverse direction is issued (step S522 → step S528 → step). S534 → step S540 → step S546). At this time,
Since “0.8 <17/10”, the fifth sentence is regarded as the target portion W at the time when the instruction to move the target portion W in the opposite direction is given.

Then, when an instruction to move the target portion W in the reverse direction is issued (step S546), the target portion W is immediately moved to the division portion (20 characters) of the second portion of the fourth sentence (step S546). S548), as shown in FIG. 23, only the attention portion W, which is the divided portion of the second portion of the fourth sentence, is displayed with 16 points, and the characters that can fit into the screen of the display device 18 are displayed with 10 points ( Step S550).

At this time, the display start position V is updated so that the vertical center of the divided portion of the second portion of the fourth sentence becomes the center of the screen.

Then, the current time is set to the reference time K (step S518), and an instruction to increase the reading speed R is given 0.9 seconds after the reference time K (step S52).
2 → step S528). At the time when this instruction is made, the reading end position P is updated so as to indicate immediately after the ninth character of the divided portion of the second part of the fourth sentence (step S530). Then, the reading speed R is changed to 11 characters / second (R = 10 × 1.1) (step S532),
The current time is set to the reference time K (step S51).
8).

Further, the reading end position P (immediately after the ninth character of the divided part of the second part of the fourth sentence) and the reading speed R (1

1 = 1.55 (seconds) "(step S52
0), T (= about 1.55) seconds (step S52
2) Then, the attention portion W is moved to the first division portion (45 characters) of the sixth sentence, and as shown in FIG. 25, only the attention portion W which is the first division portion of the sixth sentence has 16 points. Is displayed, and only 10 characters that can be displayed on the screen of the display device 18 are displayed.
Display in points (step S524 → step S5
26).

At this time, the display start position V is updated so that the vertical center of the first divided portion of the sixth sentence becomes the center of the screen.

As described above, only the portion of interest can be displayed in a larger character than other characters, and the portion of interest can be automatically moved after a lapse of a predetermined time or manually moved. Therefore, the continuous character string is extremely easy to read, and the part currently being read can be easily identified.

[Automatic Movement Mode Processing] This automatic movement mode processing is controlled by the above-described automatic movement mode processing routine.

In this automatic movement mode process, when the character string data is selected and read into the RAM 14 after the power is turned on (step S802), the input of the target character number C by the operation of the keyboard 16 is prompted, and the target character number C becomes It is set (step S804). In this operation example, a case where "22 characters" is input as the number of noticed characters C will be described.

In this way, when "22 characters" is input as the number of noticed characters C, the leading 22 characters of the character string read into the RAM 14 is set as the noticed portion W (step S80).
6) Further, the display start position V is set to the head of the character string (step S808).

As the value of the reading speed R, "10 characters /
It is assumed that “second” is input by the operation of a predetermined operator of the keyboard 16 (step S810), and the forward direction (D = 1) is set as the reading direction (step S812).

Then, as shown in FIG. 26, only the target portion W of 22 characters from the beginning of the character string is displayed at 16 points, and only 10 characters can be displayed on the screen of the display device 18.
It is displayed in points (step S814). Note that the leading blank is treated as one character here.

Then, the waiting time T is calculated and obtained (step S816). In this case, “waiting time T = (22 characters / 2) / (10 characters / second) = 1.1
