Abstract
A control device for a camera includes a single motor, a mechanism for controlling a built-in electronic flash, a mechanism for controlling a mirror, a mechanism for controlling a shutter, and a connecting mechanism that connects the single motor to those control mechanisms. The connecting mechanism operates the mirror control mechanism and the shutter charge mechanism when the motor is rotated in a forward direction, and causes the flash control mechanism to switch the electronic flash to a projected position when the motor is rotated in a reverse direction.
Claims24
A control device for controlling mechanisms installed in a camera, comprising;
- a single drive source;
- means for changing a position of a built-in electronic flash between a projected position and a retracted position;
- means for driving a mechanism other than said built-in electronic flash, said other mechanism being provided for a photographing operation of said camera;
- and
- means for connecting said drive source to said position changing means and said drive means, said connecting means being able to control at least said drive means when said drive source is rotated in a first direction, and being able to control said position changing means to move said built-in electronic flash to said projected position when said drive source is rotated in a second direction opposite to said first direction, wherein said drive means controls a photographing operation which is independent of movement of said electronic flash.
