置を設けたことを特徴とするカメラ。a reflecting mirror device movable between a first position for observing an image of a subject and a second position for retreating from a photographing optical path; and an urging means for urging the reflecting mirror device toward the first position. , moves forward in connection with a camera starting operation to move the reflecting mirror device from the first position to the second position against the urging force of the urging means, and in connection with a shutter closing operation. and a reciprocating device that allows the reflecting mirror device to move from the second position to the first position by the urging force of the urging means, and when the reciprocating device moves forward, the reciprocating device moves back and forth. The reflecting mirror device is moved to the second position by a reciprocating device, and when the reciprocating device moves back, the reflecting mirror device is moved to the first position by the urging force of the urging means following the backward movement. In a single-lens reflex camera, a light-shielding device that additionally covers the shutter opening in addition to the shutter curtain;
An interlocking device is provided for interlocking the light shielding device with the operation of the reciprocating device, and the interlocking device is configured such that the light shielding device retreats from the shutter opening when the reciprocating device moves forward, and covers the shutter opening when the reciprocating device moves backward. The camera is further provided with a device that moves the reflecting mirror device from the first position to the second position without using the reciprocating device in conjunction with a manual operation member.
