FLEXIBLE BOARD AND DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To overcome the problem in which the excess part of a flexible board is curved upward to interfere with the other member when a movable part is moved to induce excess in the flexible board in a case of connecting the flexible board between the movable part and a stationary part. SOLUTION: A movable part and a stationary part are connected together with a flexible board formed of elastic material so as to be shrinkable by its restoring force. The shrinkable part of the flexible board is formed like a spiral, by which the spiral is drawn out or taken up first when the flexible board is pulled out, so that the flexible board never interferes with the other members.
