Abstract

PURPOSE:To reduce a case that is the disconnection of a lead wire and to improve reliability, by connecting a means to detect the position of a movable member provided at the movable member in such a way that it can be connected electrically to the outside via an elastic member. CONSTITUTION:The lead wires 32 and 34 to permit a current to flow on a LED13 provided in an optical system driving device 30 are connected in the neighborhood of positions where they are fixed at the movable members 2 of the elastic members 36 and 38, and are connected to an external power source electrically via the elastic members 36 and 38. In such a way, it is possible to reduce the length of the lead wire, and to reduce the case of the disconnection of the lead wire, then, to obtain the driving device with high reliability.
