A terminal apparatus includes a portion (12) having an operation portion, a pedestal (20) which holds the main-body base portion (12) so as to be tiltable, a hook (31) which fixes the main-body base portion (12) in a tilting state at plural predetermined angles, a tooth row (224) which has teeth and engages with the hook (31) to fix the main-body base portion (12) in the tilting state at plural predetermined angles, a cam (33) which moves within the main-body base portion (12) in accordance with the tilt angle of the main-body base portion (12), and a cam control groove (226) which controls the movement of the cam (33), wherein when the hook (31) moves over the tooth at the uppermost step of the tooth row (224), the hook rides on the cam (33) thereby to release the engagement with the tooth row (224), then the hook moves downward in a state of riding on the cam (33), then the main-body base portion (12) releases the tilting and moves downward to restore to an initial position. |
