する一眼レフカメラ。 In a single-lens reflex camera configured to close the eyepiece shutter by a release operation and then raise the mirror, lower the mirror after the shutter is operated, and open the eyepiece shutter after the shutter operation is completed, the eyepiece shutter and mirror A pair of transmission gears are provided for transmitting the rotational driving force from the electric motor to an interlocking drive mechanism, and a part of the drive-side transmission gear is provided with a pair of transmission gears for maintaining the eyepiece shutter and mirror in predetermined operating positions. A toothless portion is provided, and the teeth of the driving side transmission gear adjacent to the opposite rotation direction side of the toothless portion are arranged to face each other at a predetermined interval so as not to mesh with the driven side transmission gear when the motor is stopped. A single-lens reflex camera characterized in that the motor is configured to mesh with each other to transmit rotation when the motor is driven to rotate.
