    • There is provided a camera which is compact in size and inexpensive even with the use of two motors, which allows relevant mechanisms to be laid out freely to thereby simplify motor controlling sequences, and which allows the user to quickly perform preliminary winding of a newly loaded film after film rewinding to thereby minimize the effects of film replacement during photographing. A first motor is used to drive a film winding driving system and a film rewinding driving system. A switching mechanism selectively switches between a winding state in which a driving force of the first motor can be transmitted to the film winding driving system, and a rewinding state in which the driving force of the first motor can be transmitted to the film rewinding driving system. A second motor is used to drive the switching mechanism for selective switching between the winding state and the rewinding state. A microcomputer CPU causes the switching mechanism to select the winding state after causing the switching mechanism to select the rewinding state to thereby carry out rewinding of a film, and thereafter terminates control of winding of the film.

    • A camera including a flash unit comprising an illumination-angle varying mechanism for varying a flash illumination angle. The camera includes a motor, disposed in a camera body, rotatable in a first direction and in a second direction. A clutch switches a direction of drive transmission in accordance with a switching of a direction of rotation of the motor. A first transmission system transmits a rotation of the motor to the illumination-angle varying mechanism in accordance with a switching of the clutch caused by a rotation of the motor in the first direction. A second transmission system transmits a rotation of said motor to a camera-operating mechanism other than a flash unit operating mechanism in accordance with a switching of the clutch caused by a rotation of the motor in the second direction.
