PORTABLE TERMINAL, CONTROL PROGRAM AND CONTROL METHOD
First Claim
1. A portable terminal comprising:
- a touchpad having a plurality of areas;
an illumination unit configured to illuminate the touchpad when in a lit state, and not to illuminate the touchpad when in an unlit state; and
a control unit configured to detect contact made to each of the areas of the touchpad, to perform a first judgment when detecting contact made to at least one of the areas of the touchpad during the unlit state of the illumination unit, the first judgment being a judgment of whether or not the number of areas of the touchpad to which the contact during the unlit state of the illumination unit has been made equals or exceeds a predetermined number within a first interval from the detection of the contact during the unlit state of the illumination unit, and to cause the illumination unit to enter the lit state when the result of the first judgment is negative and not to cause the illumination unit to enter the lit state when the result of the first judgment is positive.

Abstract
A portable terminal pertaining to the present invention comprises: a touchpad having a plurality of areas; an illumination unit that illuminates the touchpad in lit state, and does not illuminate the touchpad in unlit state; and a control unit that detects contact made to the areas of the touchpad, performs a first judgment when detecting contact made to at least one of the areas of the touchpad while the illumination unit is unlit, the first judgment being a judgment of whether the number of areas of the touchpad to which the contact during the unlit state has been made equals or exceeds a predetermined number within a first interval from the detection of the contact, and turns the illumination unit on when the result of the first judgment is negative and does not turn the illumination unit on when the result of the first judgment is positive.

7. A control program used in a portable terminal, the portable terminal including a touchpad and an illumination unit that illuminates the touchpad when in a lit state and that does not illuminate the touchpad when in an unlit state, the control program comprising:
a controlling step of detecting contact made to each of the areas of the touchpad, performing a first judgment when detecting contact made to at least one of the areas of the touchpad during the unlit state of the illumination unit, the first judgment being a judgment of whether or not the number of areas of the touchpad to which the contact during the unlit state of the illumination unit has been made equals or exceeds a predetermined number within a first interval from the detection of the contact during the unlit state of the illumination unit, and causing the illumination unit to enter the lit state when the result of the first judgment is negative and not causing the illumination unit to enter the lit state when the result of the first judgment is positive.

8. A control method used in a portable terminal, the portable terminal including a touchpad and an illumination unit that illuminates the touchpad when in a lit state and that does not illuminate the touchpad when in an unlit state, the control method comprising:
a controlling step of detecting contact made to each of the areas of the touchpad, performing a first judgment when detecting contact made to at least one of the areas of the touchpad during the unlit state of the illumination unit, the first judgment being a judgment of whether or not the number of areas of the touchpad to which the contact during the unlit state of the illumination unit has been made equals or exceeds a predetermined number within a first interval from the detection of the contact during the unlit state of the illumination unit, and causing the illumination unit to enter the lit state when the result of the first judgment is negative and not causing the illumination unit to enter the lit state when the result of the first judgment is positive.
