PROBLEM TO BE SOLVED: To provide a portable electronic appliance which is urged to close and automatically opened and turned in one operation, or manually opened/ closed in a free-stop state in which a hinge device is turned and stopped at the hand-free position if this one operation is not performed. SOLUTION: The engagement of an engagement projecting part 6 with an engagement recessed part 7 is not attached/detached, but held in a turn-locking state by an elasticity mechanism 11, and if the engagement is attached/detached by the manual turn against the elasticity mechanism 11, a free-stop state is realized, in which the hinge device is turned and stopped at the hand-free position by the returning force by the elasticity mechanism 11. The hinge device has an unlocking part 8 in which the engagement energizing force of the elasticity mechanism 11 is released, any one of the engagement projecting part 6 and the engagement recessed part 7 is automatically turned by a turning and energizing mechanism 9, and a second member 2 is automatically and relatively turned to a first member 1.
