Is shown.

FIG. 4 is a correspondence table showing the relationship between the number of characters displayed on one screen and the screen display time in the processing of FIG. 1. These information are stored in the memory 3. For example, if the number of characters displayed on one screen is 350 characters,
The screen will be displayed for 60 seconds.

Next, the processing flow of FIG. 1 will be described.

As soon as a certain document is selected from the tablet 4, which is an input device, the process proceeds to a process 100, where it is determined how many characters are displayed on the first screen.
The processing example is to calculate the number of characters for each line, and then to calculate the total number of characters, or to change the maximum number of characters of the document display area from 800 characters (20 lines × 40 characters) to a space (one character for which no characters are displayed). For example, there is a process of subtracting the sum of the regions.

Further, a processing method of adding punctuation marks or parentheses as the number of characters or a processing method of not adding them is possible.

Next, the processing shifts to step 101, where the display time of the first screen is set. As described above, information indicating the relationship between the number of characters displayed on one screen and the screen display time is stored in the memory 3. For example, if the number of characters displayed on the first screen by the process 100 is 350 characters, A screen display time of 60 seconds is set. After the display time is set by the process 101, the process proceeds to the process 102. Processing 1
In 02, the display of the first document on the display 8 is started, and the display is continued for the time set in the process 101. After the time set in the process 101 elapses, the process proceeds to the process 103.
In the process 103, it is determined whether or not there is a document to be displayed next, and if so, the process returns to the process 100 and the above process is repeated. If there is no last document, the display of the last document is deleted, or the last document is kept displayed until there is no next input instruction.

By executing the above processing, the screen switching can be automated, and the display time can be automatically changed according to the number of characters to be displayed, so that a smooth document can be read.

Next, a description will be given of an invention in which the operator can select a display time corresponding to the number of characters displayed on one screen.

FIG. 5 shows a processing flow when the operator can select a display time corresponding to the number of characters displayed on one screen.

FIG. 6 shows a screen for setting the screen display time displayed on the display 8. In the present embodiment, a case is shown in which three stages of display time of “fast”, “normal”, and “slow” can be set.

FIG. 7 is a correspondence table showing the relationship between the number of characters displayed on one screen and the screen display time in the processing of FIG. 5, and such information is stored in the memory 3. For example, when the number of characters displayed on one screen is 350 characters, the screen is displayed for 40 seconds in the process of FIG. 5 when the setting of the screen display time “fast” is set.

Hereinafter, the processing flow of FIG. 5 will be described.

When a certain document is selected from the tablet 4 which is an input device, the process immediately proceeds to a process 200. First, in process 200, the operator sets the screen display time of a document to be read. The operator can use the tablet 4 to set any of the three display times of “fast”, “normal”, and “slow” displayed on the screen display time setting screen shown in FIG. Hereinafter, a case where “fast” is set will be described.

When "fast" is set in the process 200, the process proceeds to the process 201. In the process 201, similarly to the process 100, it is determined how many display characters are displayed on the first screen.

Next, in step 202, the display time of the first screen is set based on the setting information obtained in steps 200 and 201. Information indicating the relationship between the number of characters displayed on one screen and the screen display time “fast”, “normal”, and “slow” is stored in the memory 3. For example, “fast” is selected in the process 200 and the first If the number of characters to be displayed on the screen is 350, the screen display time 4
0 seconds will be set. After the screen display time is set by the process 202, the process proceeds to the process 203. Process 203
Then, the display of the first document on the display 8 starts,
The display is continued for the time set in the process 202.

Next, after a lapse of the time set in the process 202, the process proceeds to a process 204. In the process 204, it is determined whether or not there is a document to be displayed next, and if so, the process returns to the process 201 and repeats the above process. If there is no last document, the display of the last document is deleted, or the last document is kept displayed until there is no next input instruction.

By executing the above processing, the operator can select a desired screen display time, and automatically change the display time in accordance with the number of displayed characters, thereby enabling smooth document reading. .

Next, an embodiment of the present invention for displaying the display time for each screen will be described. The present invention provides processing 1
02 or 203, the time corresponding to the document to be displayed is displayed in the guidance area as shown in FIG. 3 based on the information obtained in the processing 101 or 202 in the "display time: XX".
Seconds ". The display is performed for a time set for each display screen, for example, a processing method of continuously displaying “display time: 40 seconds” for 40 seconds, or “display time: 40 seconds” or “display time: 39 seconds”. There is a processing method for indicating the remaining display time every certain time.

As described above, in the present embodiment, the invention in which the display time is automatically set and the screen can be automatically switched mainly according to the number of display characters for one screen has been described. The display time is automatically set according to the "effective display capacity of one screen" instead of the "number of display characters per minute", and the screen can be automatically switched. Here, the “effective display capacity of one screen” is a display character displayed on one screen,
A table, a graph, an image diagram (for example, a picture of a person or an object) and the like are shown.

For example, in addition to the characters displayed on the display screen,
When there is a table, a graph, an image diagram, or the like, the total of the display time corresponding to the number of display characters and the addition time (for example, 20 seconds) is displayed as the display time of the display screen.

That is, in the processing 100 or 201, not only the number of display characters for one screen but also the presence or absence of other tables, graphs and the like are checked.
If there is a display time corresponding to the number of display characters and a table, a graph, or the like, the total time of the addition time is displayed as the display time of the display screen.

At this time, a processing method of changing the addition time according to the size of the displayed area such as a table, a graph, or an image diagram can be realized.
