PROBLEM TO BE SOLVED: To provide a folding type information terminal and its rotational angle control method for locking a rotation at a prescribed angle, even if outer force is operated in the direction of opening in a state of opening at a prescribed angle that is smaller than an angle for maximum opening, and canceling the locking by operating force other than the outer force. SOLUTION: A first enclosure 33 and a second enclosure 34 are rotatably retained by a first hinge 41 fitted to one sidewall 35A of a connection, and a second hinge 42, respectively. A lock 51 is formed on an outer periphery surface 35B of the connector, and the first enclosure 33 does not rotate in the direction marked by an arrow 46 when a projection 33D is pressure-welded to the outer periphery surface 35B while a lock knob 52 is being locked to the lock 51. When the lock knob 52 is moved in the direction marked by an arrow 57 for canceling the locking, rotation is made in the direction marked by the arrow 46. COPYRIGHT: (C)2005,JPO&NCIPI
