Zoom lens drive system for lens shutter type of camera

A zoom lens camera having a finder optical assembly and a photographic optical assembly including a movable zoom lens system having a plurality of lenses, said finder optical assembly and said photographic optical assembly having different optical axes, said camera comprising:

• a motor and a cam assembly, driven by said motor, for moving said photographing optical system within a zooming photographic range in which the focal length of the lenses in said zoom lens system will vary, and for moving said photographic optical assembly between a position at one end of said zooming photographic range, and a collapsed position in which said zoom lens is located rearwardly of said zooming range;
• a code plate having at least one area for obtaining focal length information relating to the focal length position of said photographic optical system, said at least one area including a detecting portion comprising means for determining that said photographic optical system is positioned between said collapsed position and said one end;
• and
• means for preventing said motor from stopping driving of said cam assembly when said photographic optical system is determined to be positioned between said collapsed position and said one end.
