Abstract

The electronic apparatus according to the present invention comprises a first display unit 20 placed on one surface of a housing, a second display unit placed on the other surface opposite to said first display unit and provided with approximately the same display area as that of said first display unit 22, a touch panel 30 overlapped at least with one of said first and second display units 20 and 22, a control unit 100 for executing tasks, displaying images on said first or second display unit 20 or 22 and receiving input from said touch panel 30.

Claims

1. An electronic apparatus comprising:

a first display unit placed on one surface of a housing;

a second display unit placed on the other surface opposite to said first display unit and provided with approximately the same display area as that of said first display unit;

a touch panel overlapped at least with one of said first and second display units;

a control unit for executing tasks, displaying images on said first or second display unit and receiving input from said touch panel.

2. The electronic apparatus according to claim 1, wherein contours of said first and second display units are curved and connected to each other in order to surround the periphery of the housing.

3. The electronic apparatus according to claim 2, wherein the contour of the housing has an approximate elliptic form including said curved first and second display units.

4. The electronic apparatus according to claim 1, wherein said control unit displays on said first display unit a screen of a task being executed, and displays on said second display unit a list screen of other tasks.

5. The electronic apparatus according to claim 1, wherein said control unit displays on said first display unit a screen of a task being executed, and displays on said second display unit a list screen of several tasks including the task being executed.

6. The electronic apparatus according to claim 5, wherein said control unit senses that a specific area of said touch panel is rubbed, replaces a task displayed on said first display unit with another new task which has been listed at the other end of the rubbing direction in the list screen on said second display unit, removes the new task displayed on said first display unit from the list screen on said second display unit, and adds the task which has been displayed on said first display unit to the list screen on said second display unit at the end of the rubbing direction.

7. The electronic apparatus according to claim 6, wherein said control unit carries out an executing screen switch caused by the task switch by a continuous scroll display.

8. The electronic apparatus according to claim 6, wherein said control unit can execute several tasks at the same time, displays executing screens of the executed several tasks on said first display unit so that an executing screen of a mainly executed task is displayed at the center in the rubbing direction and schematic executing screens of the other tasks are displayed at the upper or lower end in the rubbing direction.

9. The electronic apparatus according to claim 1, wherein said control unit enters into the rest status for stopping executing tasks except for predetermined tasks when no input from said touch panel is sensed for a predetermined time, returns from the rest status when it is sensed that a specific area of said touch panel overlapped respectively with said first and second display units is touched for a predetermined time, and displays a screen of a task being executed on the display unit which is on the same surface as the specific area being touched.

10. The electronic apparatus according to claim 1, further comprising illumination sensors arranged on the both surfaces on which said first and second display units are respectively placed,

wherein said control unit compares outputs from said illumination sensors and displays a screen of a task being executed on one of said display units placed on the surface from which a lighter illuminance is sensed.

11. The electronic apparatus according to claim 1, further comprising a position difference sensor for sensing a position of the housing,

wherein said control unit displays a screen of a task being executed on one of said first and second display units, based on a sensing result of said position difference sensor.

12. The electronic apparatus according claim 9, wherein said control unit accepts an input from one touch panel overlapped with one of said first and second display units on which a screen of a task being executed is displayed, and does not accept an input from the other touch panel overlapped with the other one of said display units.

13. The electronic apparatus according to claim 1, further comprising:

an audio input unit arranged at one side of the housing; and

an audio output unit arranged on the other side of the housing opposite to the one side on which said audio input unit is arranged.

14. The electronic apparatus according claim 10, wherein said control unit accepts an input from one touch panel overlapped with one of said first and second display units on which a screen of a task being executed is displayed, and does not accept an input from the other touch panel overlapped with the other one of said display units.

15. The electronic apparatus according claim 11, wherein said control unit accepts an input from one touch panel overlapped with one of said first and second display units on which a screen of a task being executed is displayed, and does not accept an input from the other touch panel overlapped with the other one of said display units.
