Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with interchangeable lenses, and more particularly to a camera having a storage portion for storing an interchangeable lens in a camera body.

[0002]

2. Description of the Related Art Conventionally, in order to obtain a wide angle of view with one camera, taking lenses (interchangeable lenses) having different focal lengths are used.
There is a replaceable camera.

Most of the popular single-lens reflex cameras have a lens-replaceable structure.

[0004]

However, when the above-mentioned interchangeable lens is not attached to the camera, a lens cover for protecting the lens surface is usually attached and carried separately.

In many cases, lens exchange is performed during photographing, and it is necessary to always place the lens around us. In particular, it is not easy to always carry an interchangeable lens when shooting with movement such as outdoors. A 35 mm film is usually used, but there is a more miniaturized film, and a patrone for loading this film is also miniaturized. A camera using this cartridge is downsized, the thickness of the grip portion is thinner than the conventional one, and the holding property is deteriorated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a camera body in which an accommodating portion for accommodating an interchangeable lens is provided to improve portability and clipability.

[0007]

In order to achieve the above object, the present invention provides a first camera in which the interchangeable lens is provided, in which the interchangeable lens is accommodated in the retaining section for retaining the camera. To do.

In a camera using a small film cartridge loaded with a film smaller than 35 mm film, a small aperture for defining a mask when a photographed image is projected on the film loaded in the small cartridge, and a small aperture. Provided is a second camera including a small interchangeable interchangeable lens that allows photographing light to pass therethrough corresponding to an aperture, and a storage portion that is provided in a holding portion of the camera and that stores the small interchangeable lens. To do.

In the first or second camera, the storage portion has an opening for inserting the interchangeable lens, and the cover is openable and closable between a position that shields the opening and a position that exposes it. To provide a camera.

[0010]

In the camera having the above-described structure, the camera body is composed of the interchangeable lens storage portion, which is provided in the grip portion, for storing the interchangeable lens, the lens holder under the storage portion, and the grip cover which can be opened and closed. The interchangeable lens is stored in the grip part of.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows and describes the configuration of a camera as an embodiment according to the present invention. FIG. 1A shows a schematic configuration of a cross section of the center of the camera of AA ′ shown in FIG. 1B viewed from above, and FIG. 1B is a view viewed from the front.

In this camera, the interchangeable lens is housed in the grip portion m and the grip cover is closed, and the interchangeable first interchangeable lens 1 is attached to the mount portion 6d of the camera body 6. Has been done. The aperture section 6e is sandwiched in the center, and the cartridge (small cartridge) 3 is on the right side, and the film winding chamber 4 is on the grip portion m on the left side.
A battery 5 is arranged behind the grip part m.

The second interchangeable lens 2 is accommodated inside the interchangeable lens accommodating portion 6f provided in front of the grip portion, and the openable / closable grip cover 7 is closed.

Further, as shown in FIG. 1B, when the camera is viewed from the front, a light projecting window 8 and a light receiving window 9 for distance measurement,
Photometric window 10, viewfinder objective window 11, strobe window 12
Are arranged.

FIG. 2 shows a state in which the interchangeable lens is not housed in the grip portion of the camera shown in FIG. 1 and the grip cover 7 is open. FIG. 2A shows B of FIG.
The cross-sectional structure of -B 'is shown, and the figure (b) has shown the figure seen from the front.

A rail groove 6c for opening and closing the grip cover is formed in the lower portion 6b of the camera body, and a similar rail groove 6g is formed in the upper portion a of the camera body 6 although not shown. . Two rail grooves 6c, 6g
Have the same circular shape, and the upper and lower ends of the grip cover 7 are fitted into this groove so that the grip cover 7 can be rotated to open and close. A lens retainer 13 is provided below the interchangeable lens storage portion 6f so as to urge it upward, and is movable in the vertical direction.

Even if various interchangeable lenses having different lengths are accommodated by the lens retainer 13 due to the difference in focal length, the interchangeable lenses are fixed by abutting upward.
The interchangeable lens stored inside the grip part m does not rattle. Although not shown, the mount mounting portion of the interchangeable lens has a member (contact, etc.) for transmitting the focal length information of the lens to the camera body, and the camera mounting portion has a member for receiving the focal length information of the lens. Thus, the view frame of the viewfinder is changed to a view frame that matches the focal length of the interchangeable lens attached to the mount.

The diameter of the grip portion of the camera and the diameter of the interchangeable lens will be described. A cartridge loaded with a film smaller than a general 35 mm film is downsized and the screen size is also reduced. Therefore, if the taking lens can be downsized and the present size is 0.75 times the lens diameter, for example, in a small camera manufactured by Olympus Optical Co., Ltd., the focal length is 35
The maximum shooting lens diameter of a zoom camera from m to 70 m is about 24 m
For example, if the lens length is m and the lens portion length is about 32 mm, the lens diameter becomes about 18 mm when multiplied by 0.75, and an interchangeable lens that can be sufficiently stored in the grip portion can be realized.

On the battery 5 and the film winding chamber, the main capacitor 14 for strobe is laid diagonally. The film feeding motor 15 is horizontally placed at the lower center of the main body. Although not shown, the interchangeable lens includes a piston adjusting mechanism and a pivot mechanism, which are electrically connected and driven by the connection of the mount portion of the camera body. A focal plane shutter is arranged on the front surface of the aperture.

As a modification of the finder, a TTL finder used in a single-lens reflex camera may be used.

As described above, the camera of this embodiment is housed in the camera body while protecting the interchangeable lens,
Improves portability of interchangeable lenses. Further, in a camera called a small interchangeable lens, grip performance can be improved.

The camera of the present invention is an embodiment in which one interchangeable lens is housed, but the interchangeable lens is not an interchangeable lens having a single focal length but two interchangeable lenses if a zoom lens capable of zooming the focal length is housed. However, it is possible to obtain a relatively desired angle of view.

It is needless to say that a plurality of interchangeable lenses can be accommodated as long as the space of the accommodating portion can be accommodated by downsizing the photographing lens (interchangeable lens).

[0025]

As described above in detail, according to the present invention, it is possible to provide a camera which is provided with an accommodating portion for accommodating an interchangeable lens in the camera body and which is improved in portability and clipability.

Therefore, even if the camera is miniaturized, the interchangeable lens can be stored in the camera body (grip portion) without impairing the grip performance, and it is excellent in portability, and the cover provided in the interchangeable lens storage portion prevents damage. The lens can be protected from dust and the like.
