Embodiment Construction

[0030] like image 3 As shown, in the first embodiment of the present invention, the photosensitive unit 101 includes a frame 102 and a photosensitive element (not shown) fixed therein, and the photosensitive element may be, for example, a CCD (Charge Coupled Device, Charge Coupled Device) or a CMOS ( Complementary Metal Oxide Semiconductor Transistor, Complementary Metal Oxide Semiconductor). The positioning mechanism 100 of the photosensitive unit 101 includes: a motor 103 , a cam 104 driven by the motor 103 , and a first positioning plate 105 and a second positioning plate 106 .

[0031] Wherein, the outer peripheral surface of the cam 104 is provided with a plurality of teeth, and the motor 103 meshes with the cam 104 through the gear 107, and drives the cam 104 to rotate during operation. The cam 104 is provided with a first protrusion 108 and a second protrusion 109 . The cam 104 is provided with teeth only on a part of the outer peripheral surface, and the diameters o...

Abstract

The invention relates to a positioning mechanism of a photosensitive unit of a hand vibration preventing photography device. The photosensitive unit is provided with a positioning column of the photosensitive unit; the positioning mechanism of the photosensitive unit comprises a motor, two positioning plates, a cam and an elastic element, wherein the two positioning plates are rotatablely fixed on the same fixed point, and a fixed column of the photosensitive unit is positioned between the two positioning plates; the cam is driven by the motor, and two convex columns are arranged on the cam; in the rotational process of the cam, the two convex columns can be respectively abutted against the two positioning plates, and a distance between the two positioning plates is changed to clamp or release the positioning column of the photosensitive unit; and both ends of the elastic element are respectively connected with the two positioning plates for providing restoring force which is opposite to the direction of force applied by the cam to the positioning plates. The positioning mechanism of the photosensitive unit has simple structure and is relatively stable. A method of clamping in a horizontal direction is adopted to fix the photosensitive unit, and a condition that the photosensitive unit inclines due to stress can not occur.

Description

technical field [0001] The present invention relates to components of an image capture device, and more specifically, to a photosensitive unit positioning mechanism of an anti-shake photography device. Background technique [0002] Currently, various photographic devices are equipped with an anti-shake function to compensate for image blurring caused by user's hand vibration during shooting. Common anti-shake methods include, for example, the anti-hand shake of the lens group that compensates for hand shake through the movement of specific lenses, the anti-hand shake of the photosensitive element that compensates for hand shake through the movement of the photosensitive element, and reduce the vibration by increasing the sensitivity. Electronic anti-shake affected by hand shake, etc. [0003] like figure 1 and figure 2 As shown, in a photographic device using a CCD (Charge Coupled Device, Charge Coupled Device) to prevent hand-shake, the CCD unit 2 is pressed and positio...
