PURPOSE:To enable accurate focusing on a subject on a short-distance side with two set lens positions by providing an interrupting means which stops and holds an attraction piece at a halfway position of a stroke and an operation member which interposes the interrupting means between strokes. CONSTITUTION:The attraction piece 12 is provided so that it can be put in and out of the stroke freely and the camera is equipped with the interrupting means 15 which is interposed in the stroke while a solenoid 11 is energized to stops and holds the attraction piece 12 at the halfway position of the stroke. Further, the camera is equipped with the operation member 21 which interposes the interrupting means 15 between strokes. When the solenoid 11 is energized, the attraction piece 12 is stopped at the halfway position of stroke movement and held so that the piece is not attracted into the solenoid more. Thus, even when the solenoid 11 is used for a lens driving mechanism, three lens positions are settable, so an infinite-distance position is settable in addition to a short- distance side and a long-distance side set position. Consequently, even a subject at an infinite distance position can be photographed in an accurate in-focus state. |
