Patent ID: 7918615

Claim:
An aperture-ring-and-shutter device, comprising: a base unit, comprising a base comprising a first surface, a second surface opposing the first surface, and an optical opening penetrating through the first surface and the second surface along an optical axis; a shutter unit, comprising at least one shutter sheet pivotally disposed on the base of the base unit, a shutter-driving element disposed on the base of the base unit, and a toggling element actuated by the shutter-driving element, wherein the toggling element has a guide bar utilized to rotate the at least one shutter sheet, and the shutter-driving element switches the toggling element between an opening location and a covering location, so that the guide bar of the toggling element forces the at least one shutter sheet to expose or cover the optical opening of the base unit; and a diaphragm unit, comprising a first aperture plate, a diaphragm-driving element disposed on the base of the base unit, and a toggled element pushed by the diaphragm-driving element, wherein the first aperture plate has a first aperture less than the optical opening of the base unit, and the toggled element has a guide pin utilized to rotate the first aperture plate, wherein the diaphragm-driving element drives the toggled element from a first aperture location to a large aperture location, and the guide pin of the toggled element rotates the first aperture plate, so that the first aperture of the first aperture plate and the optical opening of the base unit in superposition are switched to separate from each other; and wherein the toggled element of the diaphragm unit is switched to the first aperture location by the toggling element of the shutter unit when the toggled element of the diaphragm unit is located at the large aperture location and the toggling element of the shutter unit is switched from the opening location to the covering location, and wherein the shutter-driving element of the shutter unit comprises a first electromagnetic actuator and a first magnetic element pivoted on the base of the base unit and firmly connected to the toggling element of the shutter unit, the first magnetic element having a first axis is driven by the first electromagnetic actuator to rotate about the first axis, the diaphragm-driving element of the diaphragm unit comprises a second electromagnetic actuator and a second magnetic element pivoted on the base of the base unit and firmly connected to the toggled element, and the second magnetic element having a second axis is driven by the second electromagnetic actuator to rotate about the second axis.
