PROBLEM TO BE SOLVED: To provide an electronic equipment capable of eliminating any rattling noise caused by backlash of a gear in a driving mechanism to reciprocally drive a moving member. SOLUTION: A tip part 22 of a strip-shaped body 20 which is a spring to be multiply coiled around a coil body 55 provided on a reciprocally driving means 50 by the self restoring force is connected to a moving member 10 which is movably supported in a case 30 in the reciprocal direction indicated by A or B. The moving member 10 is movable in a reciprocal direction by pressing a feed roller 58 to be turned by the drive of a motor against the strip-shaped body 20, and uncoiling/coiling the strip-shaped body 20 from/to the coil body 55. The strip-shaped body 20 urges the feed roller 58 in the coiling direction, and generates no play attributable to the backlash of a gear 59 or the like, and no conventional slip clutch mechanism is required because a contact part of the feed roller 58 with the strip-shaped body 20 has an effect of a slip clutch.
