Patent ID: 8220759

Claim:
A terminal apparatus, comprising: a main body having an operation portion; a pedestal which holds the main body so as to be tiltable; a hook which fixes the main body to the pedestal in a tilting state at plural predetermined angles; a tooth row which has teeth and engages with the hook to fix the main body to the pedestal in a tilting state at plural predetermined angles; and a cam which moves in accordance with a tilt angle of the main body; wherein in response to movement of the hook over an end tooth of the tooth row, the hook rides on the cam thereby to release an engagement with the tooth row, and thereafter, in response to movement of the hook toward a start tooth of the tooth row, the hook moves out of a state of riding on the cam and the main body moves to restore to an initial position with respect to the pedestal, and wherein the initial position represents a position where the hook separates from the cam and the hook restores to a position capable of engaging with a tooth of a start step of the tooth row, whereby the main body restores to a position at which an angle of the main body becomes a minimum tilt angle with respect to the pedestal.
