ABSTRACT:
A controller includes a housing in which a containing portion (102) which is provided with recess supporting portions (151) on its both inner side surfaces. A shaft (152) of a rotator (153) is off-centered and supported by the supporting portions (151) in a point-contact manner. A plurality of slits (155) are formed on the rotator (153) so as to form a concentric circle with the shaft (152) as a center. Two optical sensors (156, 157; 158, 159) detect the slits at positions different from each other. On the basis of outputs of the optical sensors (157, 159), a lean angle and a leaned direction of the housing which is leaned by an operator are detected. Therefore, an image generating apparatus changes image data so as to cause an image to change according to the lean angle and the leaned direction.
