Abstract

The invention relates to an aperture shutter device, comprising a substrate unit with an aperture, a shutter unit and an aperture unit. The shutter unit comprises at least one shutter panel, a shutter drive component and a toggle component, wherein the shutter drive component can drive the toggle component to be switched between a starting position and a shielding position to ensure that the shutter panel can be switched between a state of far from the aperture and a state of shielding the aperture. The aperture unit comprises a first caliber panel with a first caliber aperture, an aperture drive component and a toggled component, wherein the aperture drive component can drive the toggled component to be switched to the first caliber position to a large caliber position in a starting position, so that the first caliber aperture is switched from a state overlapped with the aperture to the state of far from the aperture; when the toggled component is positioned at the large caliber position, and the toggled component is switched from the starting position to the shielding position, the shutter unit toggles the toggled component to be switched to the first caliber position. Therefore, the aperture shutter device ensures that power supply management of the shutter drive component and the aperture drive component can be simpler.

Description

technical field [0001] The invention relates to a photographic equipment, in particular to an aperture shutter device. Background technique [0002] Generally, when taking pictures, the required amount of light is determined by adjusting the aperture size of the photographic equipment or the opening and closing time of the shutter. [0003] refer to figure 1 , is a miniaturized lens group 4 of the certificate number I237158 patent case, mainly by controlling the direction of the current passing through the first driver 41 and the second driver 42, so that the first and second drivers 41, 42 generate Forward and reverse, and then make the first driving member 41 drive the small aperture hole 43 away from or overlap with the large aperture hole 44, and make the second driving member 42 drive the shutter plate 45 to cover or move away from the large aperture hole 44, so that The amount of light entering the miniaturized lens group 4 can be controlled. [0004] Although the a...
