HEART CAM MECHANISM AND CONNECTOR FOR PUSH-PUSH TYPE CARDS

摘要

PPROBLEM TO BE SOLVED: To prevent occurring of a phenomenon that a heart cam or an ejection lever quickly returns even if a hand is held away from the heart cam or the lever, whether it is on the way to be pushed in or to be released. PSOLUTION: The heart cam mechanism is provided with a heart cam 4C, a cam follower 6 guided by a cam groove fitted at the heart cam, and an elastic member 5 biasing the heart cam toward an exhaust (release) direction of an object (a card, a door or the like). The cam groove has shapes (wave shapes or the like) for changing a progress direction of the cam follower at either a guide part 4C4 used for pushing in the object or a guide part 4C9 used for releasing the object, in order to control biasing force of the elastic member.
