DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called movie camera mainly for recording moving images and using a cassette magnetic tape as a recording medium, and a so-called movie camera using a silver halide film as a recording medium for photographing still images. The present invention relates to a still camera-integrated movie having a still camera and an integral structure.

[0002] This product therefore enables simultaneous shooting of a video movie camera and a still camera,
The same subject can be recorded on a magnetic tape and a photographic film, which adds further value to both products.

[0003]

2. Description of the Related Art Conventionally, a video movie camera mainly for shooting a moving image and a still camera for recording a still image on a film are separate devices.
Despite having the same shooting opportunity, simultaneous shooting was difficult because one had to use one and then use the other. For a structure that solves the above problem by integrating these devices, there is, for example, U.S. Pat. No. 4,829,383 (Japanese Patent Application Laid-Open No. 63-261242).

In the above-mentioned US Pat. No. 4,829,383, a video camera and a still camera are accommodated in a single casing, and an independent casing constituting a part of the front face is attached to a front face of the casing. The body is equipped with the necessary mechanisms for a still camera, such as an optical system and a film take-up mechanism, and the housing is rotatably mounted on the casing to allow loading and unloading of the film. An opening for loading a cassette is formed. Further, in this integrated camera, the respective imaging lenses of the video camera and the still camera and the objective lens of the optical finder are provided on the front surface of the casing, but the position of the objective lens of the finder and the mounting position of the two imaging lenses are different. The positions are at different intervals.

[0005]

The above-mentioned U.S. Pat. No. 6,085,067 discloses a structure in which a video tape is inserted into and taken out of an upper portion of a housing. Since the surfaces of the still camera become parallel, it is difficult to provide a structurally separate lid. In addition, there is an open / close lid on the exterior of the housing.
This is not preferable because the operation becomes complicated and the structure becomes complicated.

In the above conventional example, the optical path of the optical finder is long due to the structure, so that the number of optical components is increased, which occupies a wasteful volume. In addition, there is a problem in that the parallax of the optical viewfinder occurs in both the vertical and horizontal directions with respect to each camera lens. The present invention has been made in view of the above problems, and in a still camera-integrated movie in which a video movie camera and a still camera are integrated, mounting a cassette of a video movie camera,
By configuring the take-out lid with a still camera,
With the lid as one place, the tape cassette and film can be easily mounted and unloaded, and the structure is simple.
Another object of the present invention is to obtain a still camera-integrated video movie in which parallax between the optical viewfinder and both cameras is reduced.

[0007]

A movie camera, wherein the still camera is incorporated in a lid portion for inserting and ejecting the magnetic tape cassette.

According to a second aspect of the present invention, there is provided the still camera-integrated video movie camera according to the first aspect, wherein a back cover for mounting and exchanging a film of the still camera is provided.
A still camera is incorporated so as to be located inside the lid. According to the third aspect of the present invention, there is provided a video movie camera having means for converting a moving image of a subject into an image electric signal and recording the same on a magnetic cassette tape, and a still camera having means for exposing a still image of the same subject on a photographic film Wherein the entrance window of the optical finder passes through a horizontal line passing through the center of one of the imaging lens of the video movie camera and the imaging lens of the still camera and the center of the other lens. It is characterized by being arranged at the position of the intersection of the vertical lines.

According to a fourth aspect of the present invention, in the video movie camera integrated with the still camera according to the first aspect, a flat monitor for monitoring an image electric signal is provided on a side opposite to the still camera.

[0010]

According to the first and second aspects of the present invention, the film of the still camera and the cassette of the video movie camera can be exchanged by opening the lid incorporating the still camera. In addition, the back cover of the still camera is accommodated inside the integrated movie when used, so that the back cover does not inadvertently open and close.

According to the third aspect of the present invention, the relationship between the position of the imaging lens of the still camera and the video movie camera and the position of the optical finder are only shifted in the horizontal or vertical direction. Barallax is limited to only the horizontal direction or the vertical direction, and there is little deviation in the angle of view. According to the fourth aspect of the present invention, since the mounting portion of the still camera is a lid, it is possible to mount a planar monitor of an image signal on the opposite side of the still camera, so that both the still camera and the video movie can be mounted. It can be used effectively as a monitor.
