PURPOSE:To constitute so that winding is inhibited when there is no electric power supply battery which is in a B.C. level or below by use of a signal of a member interlocked with a magnet in a camera, and replacement of the battery is informed to a user, by adding a simple clamping member to a member interlocked with a winding mechanism. CONSTITUTION:When a release member 1 is pushed against an operation of a spring 2, at first, an electric power supply switch 17 turns on. When the switch 17 is turned on, if a battery exceeds a B.C. level, a magnet 16 attracts an armature 15, and if it is in a B.C. level or below, said magnet does not attract the armature. When the release member is further depressed, at its final stage, another rise part 1e of the release member pushes the other end 7b of a clamping lever 7, release clamping to a running member 4, and the running member 4 descends downward by a spring 5. When the battery is in a B.C. level or below, the magnet has no attracting force, therefore, when a notched part 4b of the running member comes to a position of pawl 12a of a stopping member 12, the stopping member 12 rotates clockwise by a spring 13, enters the notched part 4b, and stops running of the running member 4. |
