Set c.
The foreign object avoidance display area 42c is an area deformed so as to avoid the foreign object contact area 42b, and characters are arranged in the horizontal direction in the irregular foreign object avoidance display area 42c.
For this reason, the number of characters that can be displayed in the foreign object avoidance display area 42c is smaller than the number of characters that can be displayed in the display area 42a. After setting the foreign object avoidance display area 42c, the control unit 10 extracts text data to be displayed based on the number of characters that can be displayed in the foreign object avoidance display area 42c from the text data being displayed in the display area 42a. Then, a process of displaying in the foreign object avoidance display area 42c is performed. With this process, when the display area is switched from the display area 42a to the foreign object avoidance display area 42c, the text data can be continuously displayed without being lost.

FIG. 5 is a flowchart showing the operation of the mobile phone 1 according to the document display function.
The control unit 10 first reads the text data of the document stored in the storage unit 11 (step S11), and waits until an instruction to start display is given by the operation of the operation unit 20 (step S12).
Here, when the operation of touching the display panel 42 or the operation of pressing the key of the key input unit 22 is performed by the speaker and the display start is instructed (Step S12; Yes), the control unit 10 stores the storage unit. 11 is extracted from the text data of the original read from 11 to display the text to be displayed in the preset display area 42a (step S13). continue,
The control unit 10 starts displaying the display target text on the display area 42a of the display panel 42 (step S14).

After starting the display, the control unit 10 monitors the operation signal input from the operation detection unit 23, and determines whether or not the touch sensor 21 has detected contact with the display panel 42 (step S1).
5). Here, when contact is not detected (step S15; No), the control part 10 transfers to step S17 mentioned later.
When contact with the display panel 42 is detected (step S15; Yes), the control unit 10 identifies the contacted area, that is, the area where the display panel 42 is hidden by the foreign matter that has touched the display panel 42. (Step S16). This hidden area can be identified from the coordinates of the contact position by acquiring the coordinates of the contact position (operation position) from the operation signal input from the operation detection unit 23 to the control unit 10, for example. Control unit 1 that identifies the hidden area
0 shifts to step S17.

In step S <b> 17, the control unit 10 determines whether or not the state of the area hidden on the display panel 42 has changed from the previous process.
When it is detected that a part of the display panel 42 is hidden and processing corresponding to this has already been performed, or when the state where the display panel 42 is not hidden at all continues, the display state There is no need to change. Therefore, the control unit 10 changes the appearance of the display on the display panel 42 based on whether or not the display panel 42 is hidden and whether or not the hidden area is enlarged / reduced or moved. It is determined whether or not.
Here, when there is no change in the appearance of the display panel 42 (step S17; No), the control part 10 transfers to step S23 mentioned later.

On the other hand, when there is a change in the appearance (hidden state) of the display panel 42 (step S17;
Yes), the controller 10 determines the area specified in step S16, that is, the foreign object contact area 42b.
In order to avoid this, a foreign object avoidance display area 42c is newly set (step S18), and the number of displayable characters and the number of displayable lines per line in the new foreign object avoidance display area 42c are
For example, it is calculated based on the size, character size, font, etc. of the foreign object avoidance display area 42c (
Step S19).
Then, the control unit 10 determines whether or not all the display target text currently displayed in the currently set display area 42a or foreign object avoidance display area 42c can be displayed in the newly set foreign object avoidance display area 42c. (Step S20).
Here, all of the display target text being displayed is newly set as the foreign object avoidance display area 42c.
If it cannot be displayed, the control unit 10 extracts a part to be newly set as the display target text from the display target text being displayed (step S21). This extraction is a process of extracting only the number of characters that can be displayed in the newly set foreign object avoidance display area 42c from the top of the display target text being displayed.

Thereafter, the control unit 10 updates the display on the display panel 42 (step S22). In this step S22, the display area on the display panel 42 is switched to the newly set foreign object avoidance display area 42c under the control of the control unit 10, and the newly set display target text is extracted from the foreign object avoidance after switching. It is displayed in the display area 42c.
Further, when the control unit 10 can display all of the display target text being displayed in the newly set foreign object avoidance display area 42c (step S20; Yes), the control unit 10 proceeds to step S22 and updates the display on the display panel 42. Then, the display area of the display panel 42 is switched to the newly set foreign object avoidance display area 42c, and the display target text previously displayed is displayed in the foreign object avoidance display area 42c after the switching.

Thereafter, the control unit 10 determines whether or not a screen display scroll is instructed by an operation on the key input unit 22 (step S23). When display scrolling is instructed here, the text data of the portion following the display target text is acquired from the text data of the original read from the storage unit 11, and this text data is converted into a new display target text. In step S24, the display on the display panel 42 is updated to display a new display target text (step S25).
Then, the control unit 10 determines whether or not display termination is instructed by an operation on the key input unit 22 (step S26). If there is no display termination instruction, the process returns to step S15. Also,
When the display end is instructed, the setting of the foreign object avoidance display area 42c and the display target text on the display panel 42 are canceled, and the display of the display target text on the display panel 42 is ended.
If the display scroll of the screen is not instructed (step S23; No), the control unit 10 proceeds to step S26 as it is and determines whether there is an instruction to end the display.
