Camera having a photo-taking lens barrel movable in the direction of the optic axis

A camera having a photo-taking lens barrel displaceable in the direction of an optic axis, said lens barrel including:

• a photo-taking optical system having said optic axis;
• a lens barrier blade member disposed forwardly of said optical system and movable in a plane orthogonal to said optic axis between a closed position for covering the front of said optical system and an opened position for exposing the front of said optical system;
• and
• an outer shell member surrounding said optical system and said barrier blade member;
• said barrier blade member having an outer edge portion adapted to bear against an inner peripheral surface of said outer shell member when said barrier blade member is in said opened position.

A camera comprising:

• a camera body member;
• a photo-taking optical system having an optic axis;
• lens barrier means having a barrier blade member disposed forwardly of said optical system and movable between a closed position for covering the front of said optical system and an opened position for exposing the front of said optical system;
• a shutter device having a shutter blade member opened and closed to expose a film to light, and means for driving said shutter blade member;
• an outer shell member formed in a cylindrical shape and holding said optical system, said lens barrier means and said shutter device, said outer shell member having first and second end openings through which said optic axis passes and surrounding said optical system, said lens barrier means and said shutter device;
• and
• means for moving said outer shell member along said optic axis relative to said camera body member, whereby said optical system, said lens barrier means and said shutter device are movable with said outer shell member.
