<p>PROBLEM TO BE SOLVED: To provide an information processor having a compact book type case body such as a palm size PC or a mail terminal capable of maintaining a certain closing locking force in a state that the case body is closed, and opening the case body without making it necessary to place the hand of a user on a function constituting component incorporated into the opened edge part. SOLUTION: An opening and closing locking/releasing mechanism of a main body part 11 and a cover part 12 is constituted so that a releasing button 21 for releasing the locking of a lock piece 19 in a lock hole 20 can be separated and arranged at the left side opposite to the right side where a camera part 17 is arranged at opened edge parts (11a, 12a). In a state that the case body is closed, the lock piece 19 is certainly locked to the lock hole 20 so that this case body can be prevented from unintentionally opened due to any other outer force other than the releasing button 21, and at the time of opening the case body, the thumb of a user is necessarily placed on each opened and closed edge face 11a and 12a at the left side of the opened edge parts where the releasing button 21 is arranged so that the case can be opened. Thus, there is no danger of adding an opening operation force to the camera part 17 and the camera part can be prevented from being damaged.</p> |
