摘要： A single lens reflex camera having:a first mirror including a portion for allowing passage of light therethrough;a second mirror for receiving the light passing through the first mirror and coupled to the first mirror in rotatable relation thereto;a drive mechanism for driving the first and second mirrors, the drive mechanism being rotatable about a shaft and connected to the first mirror in rotatable relation thereto at a position offset from the shaft, the drive mechanism having an actuating portion for the second mirror; anda hindering device for hindering the first mirror from retracting from an optical path when the second mirror is being folded onto the first mirror as the drive mechanism rotates to drive the first and the second mirrors.
