FOLD ABLE MOBILE ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a foldable mobile electronic device that can select a display direction matching a relative angle even when the relative angle between 1st and 2nd cases is changed according to a holding way or a use of the device and ensure excellent operability independently of the relation of positions of the 1st and 2nd cases. SOLUTION: In the foldable mobile electronic device where the 1st case 10 provided with a reception section and display section 11 and the 2nd case 20 provided with a transmission section are mutually foldably connected by a hinge, the 1st case 10 is turnable around a turning shaft 2 placed nearly perpendicularly to the front side of the reception section or the transmission section, when the 1st case 10 is turned from an opening state or a closing state, the display direction of the main display section 11 on the 1st case 10 is switched depending on the turn angle and a hold angle of the device.
