FOLDING TYPE ELECTRONIC DEVICE AND ITS FLEXIBLE BOARD

摘要

PROBLEM TO BE SOLVED: To improve reliability of a device by reducing a deterioration of a board so that flexible boards are not complicatedly rubbed with each other in response to an opening/closing operation of a housing. SOLUTION: The flexible board 40 is formed in a crank-like state. With its intermediate part 43 as a shaft, first and second bands 41 and 42 are wound so as to be sequentially superposed on the same circumferential surface whole holding the bands 41 and 42 in substantially same width to constitute two independent roll-like buffers. The buffers are respectively housed in cavities of hinges 30. Distal ends of the first and second buffers 41 and 41 are pulled into first and second housings 10 and 20 through openings formed at side faces of the hinges 30, and then connectors 45 and 46 attached to the distal ends are respectively connected to connectors 51 and 52 of circuits 13 and 23 mounted in the first and second houses 10 and 20.
