A lens shutter system has an inner drive ring which is rotated by a drive motor and an outer drive ring which is rotated by the drive motor. A plurality of shutter blades of the lens shutter system are driven through drive pins of the inner drive ring and drive pins of the outer drive ring so as to be opened and closed or are rotatably supported by the respective pins of the rings. Upon shutter opening, only the inner drive ring is driven clockwise to open the shutter blades. Upon shutter closing, only the outer drive ring is similarly driven clockwise to close the shutter blades. As mentioned above, upon switching between shutter opening mode and shutter closing mode, the direction of rotation of the inner and outer drive rings is not changed. Thus, the shutter operation can be performed at high speed.

The invention relates to an optical sensor and an electronic device. When no light enters a photodiode, a second current mirror circuit operates. Consequently, a current that decreases a potential difference between two terminals of a light-receiving element flows into a transistor of the second current mirror circuit and an output of an optical sensor becomes low. Meanwhile, when light enters the photodiode, a transistor of the light-receiving element is turned on and the second current mirror circuit stops operating. Consequently, the current that decreases the potential difference between the two terminals of the light-receiving element is stopped in the transistor of the second current mirror circuit and the output of the optical sensor becomes high. This makes it possible to provide an optical sensor that has a circuit in which an output of a light-receiving element does not depend on a photocurrent and that is capable of operating at a high speed.
