Abstract

Provided is an electronic device including: a device main body that processes data; a display device arranged in the device main body to display the data; a first operation device arranged in the device main body on a display surface side of the display device within a movable range of fingers of a hand for holding the device main body; a second operation device arranged in the device main body on an opposite side of the display surface within the movable range of the fingers of the hand for holding the device main body; and a control circuit that causes, only when one of the first operation device and the second operation device is being operated, the other to function.

Claims

1. An electronic device, comprising:

a device main body including processing circuit that processes data;

a display device arranged in the device main body to display the data;

a first operation device arranged in the device main body on a display surface side of the display device within a movable range of fingers of a hand for holding the device main body;

a second operation device arranged in the device main body on an opposite side of the display surface within the movable range of the fingers of the hand for holding the device main body; and

a control circuit that causes, only when one of the first operation device and the second operation device is being operated, the other to function.

2. The electronic device according to claim 1,

wherein the first operation device comprises a key devices;

and

the second operation device comprises a pointing device.

3. The electronic device according to claim 1,

wherein the first operation device comprises press-button type operation keys;

and

the second operation device comprises a touch pad.

4. The electronic device according to claim 1,

wherein the display device displays the data on a page basis.

5. The electronic device according to claim 1,

wherein the device main body comprises first and second casings;

the first casing comprises a first display device; and

the second casing comprises a second display device disposed on a surface side thereof corresponding to the first display device.

6. The electronic device according to claim 5, further comprising:

a hinge that connects the first casing and the second casing to each other, and is used for one of opening the first casing and the second casing in a double-spread form and closing the first casing and the second casing.

7. The electronic device according to claim 5,

wherein the first operation device is disposed in at least one of the first casing and the second casing;

and

the second operation device is disposed in at least one of the first casing and the second casing.

8. The electronic device according to claim 5,

wherein the first operation device is disposed in an outer frame of the display device arranged in the first casing and an outer frame of the display device arranged in the second casing;

and

the second operation device is disposed in at least one of the first casing and the second casing.

9. The electronic device according to claim 2,

wherein the control circuit causes the second operation device to function only when the first operation device is being operated.

10. A data processing device, comprising:

a display device arranged in a device main body to display data;

a first operation device arranged in an outer periphery of a display surface of the display device within a movable range of fingers of a hand for holding the device main body;

a second operation device arranged in the device main body on an opposite side of the display surface within the movable range of the fingers of the hand for holding the device main body; and

a control circuit that causes, only when one of the first operation device and the second operation device is being operated, the other to function.

11. The data processing device according to claim 10,

wherein the first operation device comprises a key device;

and

the second operation device comprises a pointing device.

12. The data processing device according to claim 10,

wherein the first operation device comprises press-button type operation keys;

and

the second operation device comprises a touch pad.

13. The data processing device according to claim 10,

wherein the display device displays the data on a page basis.

14. The data processing device according to claim 10,

wherein the device main body comprises first and second casings;

the first casing comprises a first display device; and

the second casing comprises a second display device disposed on a surface side thereof corresponding to the first display device.

15. The data processing device according to claim 14, further comprising:

opening/closing means for connecting the first casing and the second casing to each other, which is used for one of opening the first casing and the second casing in a double-spread form and closing the first casing and the second casing.

16. The data processing device according to claim 14,

wherein the first operation device is disposed in at least one of the first casing and the second casing;

and

the second operation device is disposed in at least one of the first casing and the second casing.

17. The data processing device according to claim 14,

wherein the first operation device is disposed in an outer frame of the display device arranged in the first casing and an outer frame of the display device arranged in the second casing;

and

the second operation device is disposed in at least one of the first casing and the second casing.

18. A data processing device, comprising:

display means for displaying data, which is arranged in a device main body;

a first operation means arranged in an outer periphery of a display surface of the display device within a movable range of fingers of a hand for holding the device main body;

a second operation means arranged in the device main body on an opposite side of the display surface within the movable range of the fingers of the hand for holding the device main body; and

control means for causing, only when one of the first operation means and the second operation means is being operated, the other to function.

19. A data processing method, comprising:

detecting an operation of one of a first operation device arranged on one surface side of a device main body and a second operation device arranged on the other surface side of the device main body; and

processing based on an operation of the other of the first operation device and the second operation device only when a detection of the operation is being maintained.

20. The processing data method according to claim 19,

wherein the processing based on the operation of the other of the first operation device and the second operation device comprises processing for a display image displayed on a display surface of a display device arranged in at least one of one surface side and the other surface side of the device main body.
