    a first touch type position detector which detects a first touch position of a human body on a first detection surface of the device body, the first detection surface being a surface with which images are displayed so as to be viewable;

    a second touch type position detector which detects a second touch position of the human body on a second detection surface of the device body, the second detection surface being on an opposite side of the device body from the first detection surface;

    an input processor which receives information of the detected second touch position; and

    a detection area restrictor which determines a restricted area on the second detection surface according to information of the first touch position and information determined in advance, and which prevents information of any touch position of the human body within the restricted area from being received by the input processor, whereinthe information determined in advance comprises data indicating a relation between the first touch position on the first detection surface and the restricted area on the second detection surface,the information determined in advance comprises an average value of data of a plurality of persons, each of the data of the persons being a relation between an operation area and a certain position,the operation area is acquired based on a touch position of a forefinger or a middle finger on the second detection surface when a thumb is touched on at least one position of the first detection surface in a case that the device body is held with the thumb and the forefinger or the middle finger, andthe certain position is the one position of the first detection surface.
