<p><P>PROBLEM TO BE SOLVED: To provide a portable telephone set for achieving large display while miniaturizing a main body, and for improving its operability. <P>SOLUTION: This portable telephone set is provided with: a display member; a position detection sensor for detecting the development quantity of display member; and a control part. The display member is provided with a touch panel region where a touch sensor is installed, and stored so as to be wound around a winding shaft. When the development of the display member is detected, and lock at each lock position is not detected ("NO" in step S1-1), the control part executes the invalidation processing of a touch sensor function (step S1-2). When the first lock position is detected, or when the second lock position is detected and an "operation display part output mode" is set, the control part executes the validation processing of the touch sensor function (step S1-8). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
