記載の焦点距離切換えカメラ。[Scope of Claim for Utility Model Registration] (1) In a focal length switching camera configured to switch the focal length of a photographic lens by transmitting the rotational force of a motor to a focal length switching system, a motor switch that turns the motor on and off; and a switch displacement member that turns the motor switch ON and OFF, and an OFF cam surface that is rotated by the motor and that turns the motor OFF and an ON cam surface that turns the motor ON that alternately and continuously in the circumferential direction. A motor control cam that displaces the switch displacement member by this cam surface, a pushing part formed on this motor controlling cam, a switching member that is pushed by this pushing part and switches the focal length, and the O
A focal length switching camera comprising a focal length switching knob for displacing a switch displacement member located on an FF cam surface so as to turn on a motor switch. (2) The utility model characterized in that the pushing part is a pushing pin eccentrically formed to protrude from the motor control cam, and the switching member is a switching lever that swings in contact with the pushing pin. A focal length switching camera according to claim 1.
