Mobile information terminal
First Claim
1. A mobile information terminal comprises a display device, a plurality of operation keys disposed on a surface opposite to a surface on which the display surface of said display device is disposed, finger position detecting mechanisms for detecting that a finger of an operator is placed on each of said operation keys, and a 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 comprises a display device, a plurality of operation keys disposed on a surface opposite to a surface on which the display surface of said display device is disposed, a gravity sensor for detecting whether gravity is applied in a direction from the side of said display surface of said display device to the opposite side, or whether gravity is applied in the opposite direction, 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 executes 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.
