FOLDING ELECTRONIC APPARATUS

摘要

A folding electronic apparatus with a hinge device having a first installation frame (10) installed on a first housing (2); a second installation frame (20) installed on a second housing (3); a third installation frame (30) for rotatably supporting a base end section of each of the frames, the base end sections being supported such that a head section side of each frame is rotatable in a direction to approach to and separate from each other, the base end sections being supported through a first main shaft (40) and a second main shaft (50) that are arranged parallel to each other and to which rotation of the frames is transmitted; a rotation force transmission mechanism (80) disposed between the main shafts (40, 50) and including an even number of gears (81, 82) having a function of transmitting reversing rotational force from one to the other and vice versa; and a rotation angle restriction means (60). The hinge device enables stable closing operation of the electronic apparatus, in which displacement between the housings does not occur.
