Camera with a built-in winder

Abstract

A single lens reflex camera has a built-in winder which includes a reciprocating member reciprocatable in response to forward and reverse rotations of a motor for automatic charge-up of the camera mechanisms as well as for automatic film wind-up. A charge-type drive mechanism has a charge member which is pushed by the reciprocating member upon the forward movement of the latter due to the forward rotation of the motor to move forward for causing the charge-type drive mechanism to store a driving force. The reciprocating member retracts from the charge member upon its return movement so as not to impede return movement of the charge member. An operation mechanism such as a shutter is operated for photographing under the driving force stored in the charge-type drive mechanism, accompanying return movement of the charge member. A film advance mechanism advances a film in response to the return movement of the reciprocating member due to the reverse rotation of the motor. Furthermore, clutch mechanisms interlocked with a manual selection member are capable of connecting the motor to a film rewinding shaft while disconnecting the motor from the reciprocating member, so that automatic film rewinding is also made possible.
