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 main body including processing circuit that processes data, wherein the main body comprises first and second casings where the first casing comprises a first display device on a surface side and where the second casing comprises a second display device disposed on a surface side wherein the surface sides of said first and second casing correspond to each other;

at least one first operation device arranged in the main body on either or both said first and second casings on said surface side of said first or second casing within a movable range of fingers of a hand for holding the main body, wherein the first operation device comprises press-button type operation keys;

at least one second operation device arranged in the main body on either or both said first and second casings on an opposite side of said first or second casing relative to said surface side within the movable range of the fingers of the hand for holding the main body, wherein the second operation device comprises a touch pad; 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 at least one of the first and second display devices displays the data on a page basis.

3. The electronic device according to claim 1, 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.

4. The electronic device according to claim 1,

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 only one of the first casing and the second casing.

5. The electronic device according to claim 1, wherein the first operation device is disposed in each of an outer frame of the first display device arranged in the first casing and an outer frame of the second 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.

6. The electronic device according to claim 1, wherein the control circuit causes the second operation device to function only when the first operation device is being operated.

12. The electronic device of claim 1 further comprising means for inputting data from a communication network.

7. A data processing device, comprising:

a main body which comprises first and second casings where the first casing comprises a first display device on a surface side and where the second casing comprises a second display device disposed on a surface side wherein the surface sides of said first and second casing correspond to each other;

at least one a first operation device arranged in an outer periphery of at least one of the first casing and the second casing within a movable range of fingers of a hand for holding the main body, wherein the first operation device comprises press-button type operation keys;

at least one second operation device arranged in the main body on either or both said first and second casings on an opposite side of said first or second casing relative to said surface side within the movable range of the fingers of the hand for holding the main body, wherein the second operation device comprises a touch pad; 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.

8. The data processing device according to claim 7, wherein at least one of the first and second display devices displays data on a page basis.

9. The data processing device according to claim 7, 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.

10. The data processing device according to claim 7,

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 only one of the first casing and the second casing.

11. The data processing device according to claim 7, wherein the first operation device is disposed in each of an outer frame of the first display device arranged in the first casing and an outer frame of the second 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.

13. The data processing device of claim 7 further comprising means for inputting data from a communication network.
