Lens cover assembly of cameru

Abstract

A lens cap assembly for a camera includes a front panel disposed proximal to a subject, the front panel being provided with a first optical path and a supporting portion projected toward a film or an image-photographing portion, at least a pair of barriers coupled to the front panel by a hinge for opening and closing the first optical path of the front panel, plural elastic members disposed on the front panel to bias the barriers to an open position, a barrier cover fixed to the front panel to enclose the barriers to prevent the barriers from being deviated from an optical axis, the barrier cover being provided with a second optical path, a driving lever rotatably coupled to the barrier cover, the driving lever being provided with a third optical path and a projection depressing the barriers to a closed position, and a power transmission device for converting a linear motion of the barrel into a rotational motion of the driving lever or for operating a bar in a direction for closing the barriers.

Description

technical field [0001] The invention relates to a camera lens cover assembly, in particular to a lens cover assembly capable of protecting a lens set on an optical variable focal length camera or a digital still camera (digital still camera). Background technique [0002] Generally, an optical variable focal length camera or a digital still camera (hereinafter referred to as "camera") includes a lens barrel assembly. A lens cover is attached to one of the lens barrels, such as the zoom ring, to protect the lens used in the lens barrel assembly. [0003] Such a lens cap assembly is disclosed in US Patent No. 5614973 and Korean Unexamined Utility Model No. 1999-013008. [0004] The lens cover assembly disclosed in said patent is designed to open and close the lens barrel when the lens barrel is rotated. [0005] In the conventional lens cap assembly, during the energy transfer process of converting the relative repetitive motion of the lens barrel assembly into a rotational ...

AI Technical Summary

Problems solved by technology

[0005] In the conventional lens cover assembly, the efficiency of energy transfer is reduced during the energy transfer process that converts the relative repetitive motion of the lens barrel assembly into rotational motion

As a result, due to the high energy applied in the opening / closing operation of the lens cover, the camera may be overloaded, thereby increasing the waste of electric energy
