Description

  The present invention relates to a cover for protecting a lens of a camera, and more particularly to a slide cover having means for opening and closing in a sliding manner and controlling a power source of the camera.

  The lens cover that is slidably provided on the camera body for protecting the lens of the camera is similarly designed to protect the lens, but each company has developed a different structure. For example, in US Pat. Nos. 4,557,574, 6,257,776, 6,322,259, and 6,491,448, the lens cover is a container-like housing that covers the camera body in a telescopic manner. When shooting, expose the camera lens from the lens cover housing. The lens cover is provided with some operation buttons or a flash, and is electrically connected to a circuit board in the camera body by a flexible print board or a bus. However, such a structure is complicated and inconvenient for assembling work.

  U.S. Pat. Nos. 4,240,35, 4,522,478, 5,805,947, etc. also disclose a slide cover having a simple structure. That is, although it is a slide-type lens cover provided in the camera body, these all have a simple shielding action and do not have any other function for operating a switch or structure.

  The slide cover of the camera disclosed in US Pat. Nos. 5,819,127, 5,892,996, 6,079,883, 6,424,803 has a groove formed on the back surface of the slide cover. A structure in which some members are interlocked is provided. However, the structure is complicated and it is inconvenient for assembly work.

  It is said that Olympus Corporation is the first company to develop a structure that controls the power switch with a sliding lens cover. In this structure, a plate switch that contacts the start point and the end point is provided in the slide cover, and a feeling that the slide cover is clicked by the compression spring and the metal ball is given. Such a structure increases the number of built-in members, thereby increasing the thickness of the structure portion of the slide cover. In addition, if the external surface of the lens cover is not subjected to a coating process, the built-in member is exposed, and the appearance is impaired. Therefore, there is a demand for a slide cover that has a simple structure, is easy to assemble, and can reduce manufacturing costs.
