[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyepiece structure of an optical device, and more particularly, to a case in which an eyeglass lens is attracted to an eyepiece of a camera finder or a pair of binoculars, or a dirt of the eyepiece is adhered to a lens surface of the eyeglass. The present invention relates to a technique for solving problems such as adhesion.

[0002]

2. Description of the Related Art FIG. 5 shows the structure of a conventional eyepiece used in a single-lens reflex camera or the like, and FIG.
FIG. 4 shows a sectional view along the line. As shown in these drawings, in the conventional eyepiece, a finder glass member 3 is attached to a camera body cover member 1, and a finder rubber member 7 is attached to an engagement portion 5 provided on the camera body cover member 1. Is engaged. As a result, even when the person wearing the glasses removes the finder, it is possible to reduce the impact applied to the glasses and improve the familiarity between the glass surface of the glasses and the finder portion of the camera.

[0003]

In the conventional eyepiece described above, for example, a soft rubber is used as the finder rubber member 7 in order to improve the familiarity with the glasses and reduce the impact. For this reason, when the eyepiece surface of the rubber member 7 is in contact with the lens surface of the glasses, there is a problem that the lens of the glasses may be attracted to the eyepiece surface. Further, when the eyepiece surface is dirty, there is also a disadvantage that the eyepiece surface stains adhere to the lens surface of the eyeglasses when the lens surface of the eyeglasses comes into contact with the eyeglass surface.

The object of the present invention has been made in view of the above-mentioned problems in the conventional eyepiece, and prevents the eyeglass lens from adsorbing to the eyepiece surface and preventing the dirt from adhering to the eyeglass lens surface. It is an object of the present invention to provide an eyepiece that enables comfortable observation even when wearing glasses.

[0005]

According to the present invention, there is provided an eyepiece of an optical apparatus having an eyepiece made of a material having flexibility and elasticity. Has a structure in which a convex portion is provided on the eyepiece surface.

[0006]

In the above arrangement, the convex portion is provided on the eyepiece surface of the eyepiece member, so that the lens surface of the glasses does not directly contact the eyepiece surface. For this reason, the adsorption of the lens of the glasses can be completely prevented. In addition, even when the eyepiece surface is dirty, the provision of the convex portion prevents the dirty eyepiece surface from directly contacting the lens of the eyeglasses, thereby preventing the attachment of dirt.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an eyepiece according to an embodiment of the present invention, which is applied to a finder of a single-lens reflex camera. FIG. 2 is a sectional view taken along line AA of FIG. The eyepiece shown in these figures is a viewfinder rubber member 1 that engages with the engagement portion 5 of the camera body cover member 1.
1 is provided. The finder rubber member 11 is made of, for example, a material such as rubber having flexibility and elasticity, and has an eyepiece surface 15 provided with, for example, a cylindrical convex portion 13. In addition, the shape of the convex-shaped part 13, an arrangement place,
The number and the like can be arbitrarily changed depending on the size, shape, and the like of the eyepiece surface.

[0008] With this structure, even when a person wearing spectacles looks into the eyepiece for observation, the lens surface of the spectacle does not come into direct contact with the eyepiece surface 15 over a wide area. Can be completely prevented from adsorbing to the eyepiece surface 15. Further, the dirt on the eyepiece surface 15 does not adhere to the lens of the glasses.

FIG. 3 shows an eyepiece according to another embodiment of the present invention, which is applied to an eyepiece of binoculars. FIG. 4 is a side view showing an eyepiece and the like of the binoculars shown in FIG. In these figures, a columnar convex portion 21 is provided on an eyepiece surface 19 of an eyepiece rubber member 17 constituting an eyepiece of binoculars. Also in this case, the shape and number of the protruding portions, the location, and the like can be arbitrarily set.

Also in this embodiment, since the lens surface of the eyeglasses does not directly contact the eyepiece surface 19 or does not touch the wide area of the eyepiece surface, the lens of the eyeglasses is attracted to the eyepiece surface 19. Is prevented,
In addition, it is possible to prevent dirt on the eyepiece surface from adhering to a lens of eyeglasses. Further, in this embodiment, even when the binoculars are placed on a dirty surface with the eyepiece surface 19 facing down, the stain does not directly adhere to the eyepiece surface. For this reason, the eyepiece surface does not become dirty. Further, the eyepiece surface does not stick to the surface on which the binoculars are placed.

[0011]

As described above, according to the present invention, by providing a convex portion on the eyepiece surface, it is possible to accurately prevent the lens of the eyeglasses from adsorbing to the eyepiece surface, and furthermore, to prevent the eyepiece surface from being attracted. Dirt can also be prevented from adhering to the lenses of the glasses. Furthermore, even when the eyepiece is placed with the eyepiece facing down in binoculars or the like, there is an effect that dirt can be prevented from adhering to the eyepiece surface.
