Abstract

PURPOSE:To realize smooth reading by adjusting automatically sentence feeding speed according to the number of characters stored in a number of characters storage circuit and a unit display time stored in a unit display time storage circuit. CONSTITUTION:When the unit display time stored beforehand in a unit display time storage circuit 5 and the number of characters of one page portion stored in the number of characters storage circuit 6 are multiplied by each other by a display time calculation circuit 7, and a result is set in a timing circuit 8, simultaneously with it, timing is started. When the timing is finished, a timing finish signal is supplied to a control circuit 2, and it is decided whether a page being displayed on a display part 4 is a final page or not according to it. When it is not the final page, the sentence data of a next page portion is read out from a storage medium 1, and the sentence is displayed on the display part 4, and in respect of this page too, display time is calculated similarly and page feeding is performed successively. Thus, since automatic sentence feeding is performed while the sentence feeding speed is adjusted automatically according to the number of the characters of one page portion, the comfortable reading is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic reading machine with a text feed speed adjustment function.

[Prior art] Text data is stored in a storage medium such as an IC card,
It is conceivable to configure an electronic reading machine by appropriately reading and displaying this text data.

[Problem to be solved] In the above, it is possible to automatically advance text by automatically reading text data from a storage medium and displaying it sequentially, but in this case, for example, in the case of page turning, one Regardless of the number of characters in the middle, the text advance speed is constant, and pages with a large number of characters may be page-broken before you finish reading them, and pages with a small number of characters may not be page-broken even after you finish reading them, so the page feed speed is constant. It is difficult to do proper reading.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic reading machine with a text feeding speed adjustment function that allows text feeding at optimal timing and comfortable reading.

[Means for Solving the Problems] The present invention provides an electronic reading machine that reads text data from a storage medium storing text data and displays it.
a unit display time memory circuit that stores the display time per character in the automatic text feed mode; a character number memory circuit that stores the number of characters within a predetermined range of the displayed text;
A display time calculation circuit that calculates the time until the next automatic text feed is performed based on the number of characters stored in the character count storage circuit and the unit display time stored in the unit display time storage circuit; Generates an output when the display time calculated by the time calculation circuit ends
The above problem is solved by providing a 1 o'clock circuit and a control circuit that automatically advances text in accordance with the output of the clock circuit.

[Example code] Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, 1 is a storage medium such as an IC card that stores text data, 2 is a control circuit that performs various controls such as reading text data from the storage medium 1, and 3 is a storage medium 1.
and the control circuit 2, 4 is a display unit that displays a sentence based on the sentence data read from the storage medium 1 by the control circuit 2, and 5 is a display per character in automatic text feed mode. 6 is a character number storage circuit that stores the number of characters for one page displayed on the display section 4; 7 is a unit display time stored in the unit display time storage circuit 5; and the number of characters stored in the number of characters memory circuit 6, a display time calculation circuit calculates the display time of the page, 8 measures the display time calculated by the display time calculation circuit 7, and when this time measurement ends This is a clock circuit that generates an output signal.

Next, the operation will be explained along the flowchart of FIG. First, when an automatic text feed switch (not shown) is turned on, one page of text data is read out from a predetermined address in the storage medium 1 by the control circuit 2, and the text is displayed on the display unit 4. (Step ■).

At the same time, the control circuit 2 detects the number of characters for one page displayed on the display section 4, and stores this number of characters in the character number storage circuit 6. Next, the unit display time stored in advance in the unit display time storage circuit 5 and the number of characters stored in the character number storage circuit 6 are multiplied together in the display time calculation circuit 7 to determine the page displayed on the display section 4. Display time is calculated. Next, the above display time is clocked by the clock circuit 8.
Timing starts at the same time as the setting is made (step ■).
.

When the clock circuit 8 finishes counting the display time, it supplies a clock completion signal to the control circuit 2. As a result, the control circuit 2 determines whether the page displayed on the display section 4 is the final page, and when it is determined that the page is not the final page, the next page text data is read from the storage medium 1. The text is displayed on the display section 4. The display time for this page is calculated in the same manner as the above operation, and the page is displayed for that time.

In this way, pages are sequentially turned.

(Step ■).

On the other hand, when a timing end signal is supplied from the timing circuit 8 to the control circuit 2 and the control circuit 2 determines that the page displayed on the display section 4 is the last page, the automatic text forwarding operation is stopped ( Step ■).

Through the above operations, the text feed speed is automatically adjusted depending on the number of characters in one page, and automatic text feed is performed.

In the first embodiment, the text is advanced at page 111, but the present invention is not limited to this, and the text may be advanced line by line. In this case, the character number storage circuit 6 may store the number of characters in a specific line in one page, for example, the line in the center of the screen.

In other words, when text is advanced line by line, the reader assumes that he or she is always reading the line in the center of the screen.

Further, in the above embodiment, the unit display time stored in the unit display time storage circuit 5 is 1gi, but this is not limited to this, and a plurality of types of unit display times may be stored and the reader can select one at his/her discretion. It may be possible to do so.

[Effects] According to the present invention, the text advance speed is automatically adjusted depending on the number of characters within a predetermined range, and automatic text advance is performed, so the timing of text advance is not too early or too late, and the text can be smoothly advanced. It is extremely convenient for reading.
