Problems solved by technology

[0003] Also, on the above-mentioned conventional protective cover, due to restrictions on the appearance, or because of the relationship of the exterior decoration structure in front of the camera, the length of the above-mentioned guide coupling portion is shorter than the length of the protective cover in the sliding direction.
[0004] In the above-mentioned conventional protective cover, when the guide joint portion of the above-mentioned protective cover is shorter than the protective cover, and the portion of the protective cover that is not supported by the above-mentioned guide joint portion has a shape protruding from the side of the photographing lens, when there is When external force, or the force of the camera itself (clamping and holding force of the protective cover) acts on the convex part of the protective cover on the side of the photographic lens, due to the looseness of the guide groove and the elastic deformation of the guide joint part, the above protective cover has May tilt (shake) in the forward-backward direction (direction of the optical axis)
Due to this shaking, the protective cover cannot be slid in a stable manner, and the appearance of the camera is also damaged.

Embodiment Construction

[0024] Embodiments of the present invention will be described below with reference to the drawings.

[0025] Figure 1~3 is an external perspective view of a camera showing an embodiment of the present invention, figure 1 Indicates the closed state of the protective cover (non-photography state), figure 2 Indicates the state of the protective cover during opening and closing (non-photography state), image 3 Indicates the open state (photographable state) of the protective cover.

[0026] In addition, in the following description, the front-rear direction (the object side and the imaging side) along the optical axis O of the photographing lens is taken as the Z direction, and the horizontal direction perpendicular to the Z direction is taken as the X direction, and the Z direction is taken as the X direction. The up and down direction vertical to the direction is the Y direction. In addition, in the Z direction, the front (object to be photographed) is +Z, and the back (i...

Abstract

In the camera 1, the barrier 5 for opening and closing the front of the photographing les on the front of a front cover 2 is arranged. The barrier 5 is slidably supported with upper and lower guide grooves 2b, 2c to the front cover 2. A projection-like engaging part 5e which is formed to be projected to the side of the front cover 2 is provided in the inside of the barrier. The projection-like engaging part 5e is slidably engaged with the inside of a projection 2e formed to be projected from the side of the front cover 2. Accordingly, the barrier 5 is prevented from being moved forward even when barrier click force and external force are acted on the edge side of the barrier (a part covering the photographing lens) forward.

Description

technical field [0001] The present invention relates to a camera, in particular to a structure in which a protective cover (lens protective cover) in front of a switch photographic lens is combined with a camera main body. Background technique [0002] In the past cameras, the slidable protective cover used to protect the front of the photographic lens and the viewfinder window, etc., is arranged in front of the camera. It has a guide joint part extending along the sliding direction, and the guide joint part is embedded in the sliding upper and lower guide grooves (guide rails) on the side of the camera body, which can slide freely, and can be covered from the front of the camera lens, etc. In the closed position, slide to open above the retracted position above the front. [0003] Also, in the above-mentioned conventional protective cover, due to restrictions on the appearance, or because of the relationship of the exterior decoration structure of the front of the camera, ...
