Abstract

The present invention discloses a camera capable of reducing the size by reducing the range of movement of a view finder driving member which operates interlocked with an image-taking lens barrel. The camera includes an image-taking lens barrel which performs a operation in a collapse region and performs a zooming operation in an image-taking region, a view finder optical system including a movable lens unit and a view finder driving member having a cam which drives the movable lens unit. The image-taking lens barrel operates interlocked with the view finder driving member in the image-taking region and the interlock between the image-taking lens barrel and the view finder driving member is released in the collapse region.

Description

technical field [0001] The present invention relates to a camera that drives a viewfinder in conjunction with the movement of a lens barrel. Background technique [0002] Conventionally, a camera in which a viewfinder is driven in conjunction with the rotation of a rotating barrel constituting a lens barrel has been proposed (see Japanese Patent Laid-Open No. H09-211300 and Japanese Patent Laid-Open No. 2001-324749). Figure 10 with Figure 11 Shown is such a camera. [0003] In these figures, 60 is a rotating barrel constituting a lens barrel, and 170 is a viewfinder driving part. The viewfinder driving member 170 is disposed so as to be in contact with the rotating tube 60 rotating around the optical axis, and rotates together with the rotating tube 60 around the optical axis (in the direction opposite to the D direction) due to the contact of the rotating tube 60 . [0004] In addition, the viewfinder driving member 170 is biased in the direction opposite to the D direc...
