A camera has either a built-in flash unit or a removably attachable flash unit which is turnable between a retracted position and a projected position and which is provided with an illumination-angle varying mechanism. The camera includes a motor, disposed in a body of the camera, for driving the illumination-angle varying mechanism, and a transmission system, which transmits an output rotation of the motor to the illumination-angle varying mechanism. The transmission system includes a rotating wheel which has a central axis coincident with a turning axis of the flash unit. The flash unit may include a structure divided into at least three areas: a middle area, a first side area, and a second side area. A flash generating device is disposed in the middle area; a red-eye prevention lamp is disposed in the first side area; and a drive transmission system for driving the illumination-angle varying mechanism is provided in the second side area.

Camera having transmission wheel axis coincident with flash unit turning

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.

Camera using single motor to drive a flash illumination-angle varying

A camera includes a finder for inspecting an object, a illuminator for illuminating an operator's eye by which the operator looks in at the finder means, a condensing optical system for condensing a reflected light from the operator's eye, a photoelectric converter for receiving the condensed reflected light, calculator for calculating a direction of a visual axis of the operator's eye on the basis of an output of the photoelectric converter, and a condition setter operable in response to the result of the calculation of the calculator for setting photographing conditions of the camera.

A camera has a flash unit which is movable between a retracted position and a projected position and which is provided with an illumination-angle varying mechanism. The camera includes an engagement mechanism for holding the flash unit in the retracted position by engagement. A drive mechanism drives the flash unit in a direction of the projected position when the engagement of the engagement mechanism is released. A transmission system transmits an output rotation of a motor, which serves as a drive source, to each of (i) the illumination-angle varying mechanism, and (ii) the engagement mechanism. The transmission system is driven by a rotation of the motor in a first direction (a) to release the engagement of the engagement mechanism, and (b) to drive the illumination-angle varying mechanism to vary a flash illumination angle. The transmission system is driven by a rotation of the motor in a second direction to perform a camera operation other than a flash unit operation. The camera may also include one or more of a brake member for braking a movement of the flash unit, a clutch for switching a direction of drive transmission, and multiple transmission systems.
