1. 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; anda 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, andwherein 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. 2. 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; anda 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, andwherein the initial position represents a position where the hook separates from the cam at a position where the hook further moves downward from a start step of the tooth row, whereby the main body restores to a position at which the main body almost becomes horizontal with respect to the pedestal. 3. 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 is provided on the main body side and fixes the main body to the pedestal in a tilting state at plural predetermined angles;a tooth row which is provided on the pedestal side, has teeth and engages with the hook to fix the main body to the pedestal in a tilting state at plural predetermined angles;a cam which is provided on the main body side and moves within the main body in accordance with a tilt angle of the main body;a biasing member which pushes and biases the hook toward the tooth row; anda cam control groove which is provided in parallel to the tooth row and along which the cam moves,wherein in response to the main body being tilted so as to exceed the predetermined angle, the cam engages with the cam control groove to stop an upward movement according to the tilting of the main body, then the hook moves over the cam in a stopped state to release the engagement with the tooth row, the hook moves down along the cam control groove together with the cam in a state of riding on the cam by the biasing member, whereby the main body releases a tilting state and moves downward to restore to an initial position with respect to the pedestal, andwherein the initial position represents a position where the cam engages with the cam control groove on a way of a downward movement thereof to stop the downward movement according to release of the tilting of the main body, then the hook continues to move downward according to the downward movement of the main body and separates from the cam, and then the cam restores to a position capable of engaging with a tooth of a lowermost step of the tooth row by the biasing member, whereby the main body restores to a position having a minimum tilt angle with respect to the pedestal. 4. 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 is provided on the main body side and fixes the main body to the pedestal in a tilting state at plural predetermined angles;a tooth row which is provided on the pedestal side, has teeth and engages with the hook to fix the main body to the pedestal in a tilting state at plural predetermined angles;a cam which is provided on the main body side and moves within the main body in accordance with a tilt angle of the main body;a biasing member which pushes and biases the hook toward the tooth row; anda cam control groove which is provided in parallel to the tooth row and along which the cam moves,wherein in response to the main body being tilted so as to exceed the predetermined angle, the cam engages with the cam control groove to stop an upward movement according to of the main bod then the hook moves over the cam in a ed state to release the the tiltin engagement with the tooth row, the hook moves down along the cam control groove together with the cam in a state of riding on the cam by the biasing member, whereby the main body releases a tilting state and moves downward to restore to an initial position with respect to the pedestal, andwherein the initial position represents a position where the cam engages with the cam control groove on a way of a downward movement thereof to stop the downward movement according to release of the tilting of the main body, then the hook continues to move downward according to the downward movement of the main body and separates from the cam, and then the cam restores to a position exceeding a lowermost step of the tooth row by the biasing member, whereby the main body restores to a position almost horizontal with respect to the pedestal. 5. A terminal apparatus according to claim 3, wherein the tooth row has teeth each formed in a sawtooth shape, the main body is tilted and fixed at the plural predetermined angles which are tilt angles determined based on the teeth by engaging the hook with the respective teeth, respectively, and the main body is set at a maximum tilt angle when the hook engages with an uppermost step of the tooth row and set at a minimum tilt angle when the hook engages with a lowermost step of the tooth row. 6. A terminal apparatus according to claim 3, wherein the hook includes a nail portion engaging with the tooth row, a hook shaft supported by the main body and an abutment portion abutting against the cam, and the nail portion is configured to protrude toward the tooth row from the main body. 7. A terminal apparatus according to claim 3, wherein the cam includes an abutment portion abutting against the hook and an engagement potion which engages with the cam control groove to stop the movement. 8. A terminal apparatus according to claim 1, further comprising a cam control groove which is provided in parallel to the tooth row and along which the cam moves. 9. A terminal apparatus according to claim 1, wherein said hook is provided on the main body side, said tooth row is provided on the pedestal side, and said cam is provided on the main body side. 10. A terminal apparatus according to claim 1, wherein: the hook is provided on the main body, the tooth row is provided on the pedestal, the cam holds the main body and moves within the main body, the end tooth is at an end step of the tooth row, andwhen the hook moves over the tooth at the end step of the tooth row, the hook rides on the cam thereby to release the engagement with the tooth row, then the hook moves downward in states of riding on the cam, then the main body releases the tilting state and moves downward to restore to the initial position with respect to the pedestal. 11. A terminal apparatus according to claim 10, further comprising a cam control groove which is provided in parallel to the tooth row and along which the cam moves.
