From, the character codes for the number of character data corresponding to one page to be displayed on the liquid crystal display device 12 are read out and stored in the image memory 28. The liquid crystal display controller 30 uses the font RO for the bitmap data of the character shape corresponding to the character code stored in the image memory 28.
The data is read from M32 and transferred to the liquid crystal display device 12. Then, the liquid crystal display device 12 displays the bitmap data as character data.

Further, the CPU 24 uses the cursor memory 3
4. The cursor movement display means of the present invention is configured with the liquid crystal display controller 30, and the character coordinates of the cursor displayed on the liquid crystal display device 12 are set in the cursor memory 34.

As an example of specifying the character coordinates, the image display surface of the liquid crystal display device 12 has 20 characters × 15 as shown in FIG.
If it is composed of lines, the character coordinates of the first line are (0, 0), (0, 1), ..., (0, 19), and the 15th line is (14 , 0), (14, 1), ...
·, (14, 19) Then, the liquid crystal display controller 30 inverts the bitmap data of the character displayed at the position set in the cursor memory 34, and transfers it to the liquid crystal display device 12.

The input keys 18 and 20 constitute the cursor speed setting means of the present invention. By operating the input key 18, the moving speed of the cursor can be increased, and the other input key 20 is operated. By doing so, the moving speed of the cursor can be decreased. CPU 24
Sequentially updates the character coordinates of the cursor set in the cursor memory 34 according to the moving speed of the cursor set by the input keys 18 and 20. as a result,
In the book data for one page displayed on the image display surface of the liquid crystal display device 12, the position of the character displayed in reverse is based on the moving speed of the cursor set by the input keys 18 and 20, and the position of the character data is arranged. It moves sequentially according to the order.

The input key 22 is one component of the cursor movement interrupting means, and when the input key 22 is pressed, the CPU
Reference numeral 24 interrupts the updating of the character coordinates of the cursor set in the cursor memory 34, and stops the movement of the cursor displayed on the image display surface of the liquid crystal display device 12. Then, when the input key 22 is pressed again, the CPU 24 restarts the updating of the character coordinates of the cursor set in the cursor memory 34, and the cursor displayed on the image display surface of the liquid crystal display device 12 starts moving again. Is configured.

The memory 26 and the battery 36 constitute the storage means of the present invention. When the power of the apparatus is cut off, the CPU 24 stores the position information of the cursor stored in the cursor memory 34. 26, and the position information thereof is configured to be retained by the battery 36 even when the power of the present apparatus is off. Further, the memory 26 is provided with an interruption flag 26a for managing the operation status of the input key 22 which is the cursor movement interruption means. The interruption flag 26a
Is a flag that indicates whether or not the movement of the cursor is interrupted, and the set / reset is repeated by pressing the input key 22. When the cursor movement is suspended by operating the input key 22, the suspension flag 2
6a is set to "1", and conversely, when the cursor movement is not interrupted, the interrupt flag 26a is managed to be reset to "0". The input key 22 and the interruption flag 26a form the cursor movement interruption means of the present invention.

The CPU 24 and the dictionary data 38 constitute the cursor speed changing means of the present invention.
Searches the dictionary data 38 for the reading of the character corresponding to the character code stored in the image memory 28, and changes the speed of updating the character coordinates of the cursor set in the cursor memory 34 according to the number of characters of the reading. Is configured to. The speed changing process will be described later.

Next, FIG. 3 shows how the book data and the cursor are displayed on the image display surface of the liquid crystal display device 12. In this example, the book data for one page is 1
The line is composed of 15 lines of 20 characters and is displayed vertically. The character "self" on the first line is displayed as a cursor, and the cursor moves downward at the cursor movement speed preset by the input key 18 or 20. Then, after the cursor "1" on the first line, the cursor "2" on the second line is displayed. Further, after the cursor is displayed at the position of "KU" on the 15th line, the data of this first page is deleted and the data for the next one page (2
The data of the (page) is newly displayed on the liquid crystal display device 12. Then, the cursor is displayed at the uppermost character position on the first line of the second page.

Next, the operation of the information processing apparatus 10 of this embodiment will be described with reference to the flowcharts of FIGS. 4 and 5. By installing the memory card 16 in the information processing apparatus 10 of the present embodiment, the book data supplied by the memory card is taken into the information processing apparatus 10 and the liquid crystal display device 12 is read based on the book data. The case of displaying a character string and reading will be described as an example.

First, when the information processing apparatus 10 is powered on, the internal setting of the apparatus is performed (step 1, hereinafter abbreviated as S1. Other steps are the same). In this initial setting, the user can use the input keys 18 or 20 to set the moving speed of the cursor to a desired speed. Next, it is checked whether a memory card is attached to the information processing device (S2), and if it is not attached (S2).
2: No), a message prompting the user to insert a memory card is displayed on the image display surface of the liquid crystal display device 12 (S
3).

On the other hand, if the memory card is attached (S2: Yes), the device is in use before the power is turned on this time, and how far the reading progresses at that time (the power is turned off first). It is checked whether or not data (page information / character position information) related to the (state at the time of opening) is stored in the memory 26 (S4), and if it is stored (S4:
Yes), the data of the page corresponding to the page number is read from the memory card, the character string is displayed on the image display surface of the liquid crystal display device 12 (S5), and the cursor is displayed at the character position stored in the memory 26. (S6).

However, if the data is not stored in the memory 26 (S4: No), it is considered that a new reading is started, the data of the first page of the book is read from the memory card, and the liquid crystal is read based on the data. Display device 12
A character string is displayed on the image display surface of (S7). Then, the cursor position is reset and the cursor is displayed at the first character position on the page (S8). When the data of the corresponding page is displayed on the liquid crystal display device 12, the book data stored in the memory card is not divided into page units, and therefore, the number of characters that can be displayed on the image display surface of the liquid crystal display device 12 is displayed. The book data is read from the memory card and written in the image memory 28. Further, the cursor is displayed on the image display surface of the liquid crystal display device 12 by writing the character coordinates that give the cursor to the cursor memory 34.

Next, in S9, the interruption flag 26
Check if a is set to "1". When the user wants to temporarily stop reading while reading with this device, when the input key 22 is pressed, the cursor movement on the image display surface is stopped. That is, if the interruption flag 26a is set to "1", it means that the cursor movement is being interrupted, and if it is reset to "0", it means that the cursor movement is being performed.

Here, if the interruption flag 26a is reset (S9: No), the dictionary data 38 is searched, and if the character at which the cursor is positioned is a kanji, the reading is obtained (S11). It is checked whether it is necessary to change the moving speed of (S12). In the present embodiment, when the number of characters of one kanji reading is three or more, the moving speed of the cursor is changed to be slower than the speed set by the initial setting (S1) (S12: Y).
es, S13).

For example, in the display state of the book data shown in FIG. 3, the character "self" where the cursor is positioned is a kanji character, and the reading is one character "shi" from the dictionary data 38, so the moving speed needs to be changed. It is determined that there is not (S12: N
o), set the internal timer of the program (S1
4). The timer value at this time is preset for each moving speed of the cursor set by the user, and is stored in the memory 26. Then, based on the moving speed of the cursor set in S1, a corresponding timer value is obtained from the memory 26 and set in the internal timer.

Next, wait until the internal timer expires (S15), and if so (S15: Yes), write the next character coordinate in the cursor memory 34,
The cursor position moves by one (S16).

Next, it is judged whether or not the position where the cursor is moved is the last character of the displayed character string (S17). If it is not the last character (S17: No), the procedure returns to S9 and the same as above. Repeat the process. In the case of the final character, the book data for the next page is read from the memory card 16 and displayed on the image display surface of the liquid crystal display device 12 (S18). In the above processing, the processing of S17 functions as the detecting means of the present invention, and the processing of S18 functions as the updating means of the present invention.

Further, it is checked whether or not the display of all pages is completed (S19), and if not completed (S19: N).
o), returning to S8, the cursor is set to the first character.
If all pages have been displayed (S19: Yes),
The processing of the main routine ends.

As described above, when the cursor moves to the final position of the arrangement of the character string displayed on the liquid crystal display device 12, the character string displayed on the liquid crystal display device 12 is automatically updated. The user can proceed with reading smoothly without performing an operation for updating the character string.

If it is determined in S12 that the moving speed needs to be changed (S12: Yes), the timer value is changed (S13). This process will be described with reference to the display example of the book data shown in FIG. 3. In the figure, the phrase “detailed = sho” / “description = jutsu” in the phrase “detailed”
Since it becomes a kana character and becomes 3 characters, it is determined that the moving speed needs to be changed (S12: Yes). For changing the speed, the timer value set in advance corresponding to the cursor moving speed set in the initial setting (S1) is changed (S13), and is set to the internal timer of the program (S14). In this embodiment, the timer value is changed by adding the predetermined value to the original timer value. In the above processing, the processing of S12 to S14 functions as the cursor moving speed changing means of the present invention.

As described above, since the moving speed of the cursor is changed according to the reading of the character data, for example, in the case of a long kanji, the moving speed of the cursor is slower than the normal moving speed so that there is a margin. You can proceed with reading.

Regarding the change of the timer value, the timer value corresponding to the cursor moving speed preset by the user is set as the timer value per kana character, and in the case of kanji, the timer value is changed according to the number of reading characters. Double the value, 3
It may be configured to use the doubled value as the change timer value.

If it is determined in S9 that the interruption flag 26a is set to "1", S10 is executed.
Then, it is determined whether or not the input key (not shown) operated when displaying the character data of the next page is operated, and if not operated (S10: No), the process returns to S9, and again. It is checked whether the interruption flag 26a is set. On the other hand, if the reader requests the page to be updated while the cursor movement is suspended (S10: Yes
s) and proceed to S18 to display the next page.

Further, during execution of the main routine shown in FIGS. 4 and 5, key input processing as shown in the flowchart of FIG. 6 is executed as interrupt processing. In this interrupt process, only two key input processes related to this embodiment will be described.

First, it is checked whether or not the power key is operated (S20), and if it is operated (S20: Yes), the page number and cursor position information of the book data currently displayed on the liquid crystal display device 12 are displayed. The user is allowed to select whether to save (S21). When not saving (S21: N
o), the interrupt processing ends. When saving (S21: Yes), the page number currently displayed and the character coordinates indicating the cursor position are saved in the memory 26 (S22), and the interrupt process ends.

If the operated key is not the power key (S
20: No), it is checked whether or not the break key is operated (S
23) If it is operated (S23: Yes), it is further checked whether or not the interruption flag 26a is set to "1" (S24), and if it is set, it is reset to "0" (S25). Conversely, if it is reset, it is set to "1" (S26).

As described above, according to the information processing apparatus of the present embodiment, the cursor is sequentially moved and displayed in accordance with the arrangement order of the character data displayed on the liquid crystal display device 12, so that the user can move the cursor. By reading the character data and the like along the line, it is possible to efficiently proceed with reading without losing the reading position, and it is possible to reduce the fatigue of the eyes of the user.

Since the user can freely set the moving speed of the cursor by operating the input keys 18 or 20, it is possible to easily set the moving speed to a personal preference.

Further, since the movement of the cursor can be temporarily interrupted by operating the input key 22, it is convenient when the reading is interrupted for a short time.

Further, since the position of the cursor at that time is stored in the memory 26 when the power of the apparatus is cut off, it is stored in the memory 26 when the power is turned on again. The movement of the cursor can be started from the position of the cursor, and the user does not need to remember how much the reading has been done, which is very convenient.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention.

For example, in the present embodiment, the moving speed of the cursor is realized by the timer by the program, but it may be realized by the timer by the hardware counter. Further, although the character is displayed in reverse video as the cursor display, side dots or lines may be added to the character.

The data displayed on the image display surface is
It is not limited to characters, but may include symbols and the like.

Furthermore, in the present embodiment, the data on the image display surface is updated in page units, but the data may be updated in line units. For example, in the display state as shown in FIG. 3, when the cursor reaches the last character "KU" of the last line, the data for the next one line is newly displayed on the last line of the image display surface, and first The displayed data is moved and displayed line by line on the right side.
