Patent ID: 7394731

Claim:
A digital information playback apparatus comprising: a rotating body rotatable in manual rotating operation; a sensing unit for sensing a pressing force applied to the rotating body; a detecting unit for detecting a rotating amount of the rotating body; and a control unit for performing a first control, a second control, and a third control in accordance with output results of the sensing unit and the detecting unit, wherein the first control is performed such that when a pressing force applied to the rotating body is weaker than a predetermined pressing force and the rotating body is not rotated, digital information is played back; the second control is performed such that when the predetermined pressing force is applied to the rotating body and the rotating body is not rotated, the playback of the digital information is stopped; and the third control is performed such that when the predetermined pressing force is applied to the rotating body and the rotating body is rotated, the playback of the digital information is controlled in response to the rotating amount of the rotating body.
