Abstract

A display device capable of allowing a page to be turned to give a feeling as if a page is actually turned includes a memory for storing information, a display for displaying information, a page turn instruction unit for detecting that the unit itself is tilted to output a detection signal indicating the direction of the tilt, and a display control unit for receiving an instruction from the page turn instruction unit to read information of the next or previous page from the memory according to the direction of the tilt and display the read information on the display.

Claims

1. A display device comprising:

information storage means for storing information;

information display means formed of at least two openable and closable screens for displaying information;

rotation angle detection means for detecting an angle of rotation of said information display means;

display control means connected to said rotation angle detection means for controlling whether said information display means provides display or not according to the angle of rotation of said information display means; and

page turn instruction means for issuing an instruction to switch information displayed on said information display means, wherein

said display control means includes;

means connected to said rotation angle detection means for controlling whether said information display means provides display or not according to the angle of rotation of said information display means;

means connected to said page turn instruction means for switching information as a unit corresponding to the number of screens providing display of said information display means according to output of said page turn instruction means; and

means for compressing, if the number of screens providing display of said information display means decreases, information displayed on said information display means before the number of screens providing display decreases, and displaying the compressed information on a screen providing display of said information display means.

2. The display device according to claim 1, further comprising fix means for fixing said information display means at an angle of rotation in a predetermined range.

3. The display device according to claim 2, further comprising means for preventing slip, said means provided at a part touching a base, of said information display means fixed at said angle of rotation in a predetermined range.

4. A display device comprising:

information storage means for storing information;

information display means formed of at least two openable and closable screens for displaying information;

touched area detection means formed of at least two components provided to respective screens of said information display means for detecting an area of said information display means touched by a pointer; and

display control means connected to said touched area detection means for controlling whether each of the openable and closable screens provides display or not according to an area of said touched area detection means touched by the pointer, wherein said display control means includes means for causing a screen of said information display means not to provide display, the screen corresponding to a component of said touched area detection means where an area touched by the pointer is the largest.

5. A display device comprising:

information storage means for storing information;

information display means formed of at least two openable and closable screens for displaying information;

touched area detection means formed of at least two components provided to respective screens of said information dispila means for detecting an area of said information display means touched by a pointer; and

display control means connected to said touched area detection means for controlling whether each of the openable and closable screens provides display or not according to an area of said touched area detection means touched by the pointer, wherein said display control means includes;

means for controlling whether said information display means provides display or not according to an area of said touched area detection means touched by the pointer;

first means for reading information of next or previous page from said information storage means according to direction of movement of the pointer touching said detection means and displaying the read information on said information display means; and

means for compressing, if the number of screens providing display of said information display means decreases, information displayed on said information display means before the number of screens providing display decreases, and displaying the compressed information on a screen providing display of said information display means.
