Embodiment Construction

[0042] The foregoing and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of the four preferred embodiments with accompanying drawings.

[0043] Before the present invention is described in detail, it should be noted that in the following description, similar components are represented by the same numbers.

[0044] Refer to figure 2 , 3 The first preferred embodiment of the aperture shutter device of the present invention includes a base unit 1, a shutter unit 2, and an aperture unit 3.

[0045] The base unit 1 includes a base 11, a large-diameter plate 12, a main pressing cover plate 13 buckled with the base 11, and a secondary pressing cover plate 14 buckled with the base 11, wherein the base 11 It has a first surface 111 and a second surface 112 opposite to each other, a light hole 113 penetrating the first and second surfaces 111 and 112 along the optical axis Y direction, and two light holes 1...

Abstract

The invention relates to an aperture shutter device, comprising a base unit with a light hole, a shutter unit, and an aperture unit. The shutter unit includes at least one shutter plate, a shutter driver, and a toggle, and the shutter driver can drive the toggle to switch between an open position and a shielding position, so that the shutter plate is in a state away from and shielding the light hole switch between. The aperture unit includes a first aperture plate with a first aperture, an aperture driver, and a dialed member. When the aperture is in the open position, the aperture driver can drive the dialed member to switch from the first aperture position to the large aperture position, The first aperture is switched from a state overlapping with the light hole to a state away from the light hole, when the driven member is at the large diameter position and the driving member is switched from the open position to the shielding position, The shutter unit will toggle the toggled member to switch to the first aperture position, so that the power management of the shutter driving member and the aperture driving member can be simplified.

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 aperture size of the photographic equipment or the opening and closing time of the shutter are used to determine the amount of light required. [0003] Refer to figure 1 , Is a kind of miniaturized lens set 4 of the patent case No. I237158, mainly by controlling the direction of current passing through the first driving part 41 and the second driving part 42 to make the first and second driving parts 41, 42 generate Forward and reverse rotations, so that the first driver 41 drives the small aperture hole 43 away from or overlaps with the large aperture hole 44, and the second driver 42 drives the shutter plate 45 to shield or move away from the large aperture hole 44, that is, The amount of light entering the miniaturized lens group 4 can be controlled. [0004] Although the aforementioned miniaturi...
