Mobile information terminal having operation keys and a display on opposite sides
First Claim
1. A mobile information terminal comprising:
- a display device having a display surface disposed on a front surface;
a plurality of operation keys operable to detect that each of said operation keys is frilly depressed, said operation keys being disposed on a rear surface located on a reverse side of the front surface on which the display surface of said display device is disposed;
a plurality of finger position detecting mechanisms for detecting that a finger of an operator is placed on one of said operation keys even if none of said operation keys is fully depressed, anda control section to which signals from said operation keys and said finger position detecting mechanisms are entered and which can control the operation of said display device,wherein said control section executes a processing operation to cause said display device to display an image showing the arrangement of said operation keys and to change an icon which is included in the image of said arranged operation keys and which corresponds to one of said operation keys on which the operator placed his/her finger when the control section determines, according to an input signal from said finger position detecting mechanisms, that the finger of the operator is placed on said one of operation keys.

Abstract
A mobile information terminal has a front surface on which a display surface of a display device is arranged and a rear surface on which a plurality of operation keys are arranged. The mobile information terminal further has a half-depressing sensor for detecting that each of the operation keys is half-depressed and/or a touch sensor for detecting that each of the operation keys is touched. A control section executes a processing operation to cause the display device to display an image showing the arrangement of said operation keys and to change an icon which corresponds to a key of operation keys when a control section determines, according to an input signal from the half-depressing sensor or the touch sensor, that the finger of the operator is placed on this key of operation keys.

7. A mobile information terminal comprising:
-
a display device having a display surface disposed on a front surface; a plurality of operation keys disposed on a rear surface located on a reverse side of the front surface on which the display surface of said display device is disposed, a gravity sensor operable to detect whether gravity is applied in a direction from said front surface to said rear surface, or in a direction from said rear surface to said front surface, and a control section to which signals from said operation keys and said gravity sensor are entered and which can control the operation of said display device, wherein said control section is operable to execute a processing operation to cause said display device to display an image showing the arrangement of said operation keys and a processing operation to change the assignment of key codes to said operation keys in response to an input signal from said gravity sensor. - View Dependent Claims (9)
