Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a video camera equipped with a still camera, and more specifically to a movie video camera equipped with a still camera using, for example, silver halide photographic film.

BACKGROUND OF THE INVENTION While filming with a television camera with videotape recording capability, ie, a video camera, there has been a desire to record a particular scene on a methyl photograph. conventionally,
For example, I would carry both a silver-halide still camera and a video camera, and if I wanted to shoot a still scene while shooting with the video camera, I would stop shooting with the video camera and shoot with the still camera. In such a situation, you have to carry two devices, you have to stop recording with a video camera, and there is a risk of missing out on an important photo opportunity. There was a problem.

Therefore, in order to solve this problem, a still camera and a video camera are combined into one device, and a still camera is installed that allows you to operate the still camera and take still pictures without interrupting the video camera. A video camera will be required.

Such a video camera with a still camera must have both methyl and movie function sections, which poses a problem of increasing the size of the device.

By the way, it is desirable for such a device to have a grip part for the operator to hold in consideration of convenience when taking pictures.Therefore, in order to make the device smaller, this grip part is also equipped with a still image. Alternatively, it may be possible to store part of the movie's functional parts.

However, since the grip part is connected to the main body of the apparatus at an angle, it is difficult to accommodate a part of the still or movie functional part in this part.

OBJECTS In view of these demands, an object of the present invention is to provide a video camera with a still camera that is convenient to carry, has good operability, and can be downsized.

DISCLOSURE OF THE INVENTION According to the present invention, there is provided a still camera having a still camera unit that images a scene and records a still image thereof, and a video camera unit that images a scene and records the moving image on a videotape. A video camera with a camera includes a casing body that accommodates a video camera part and has an imaging optical system for the video camera opened in the front, and a casing body that is connected to the casing body at an angle to the casing body, and the video camera with a still camera can take pictures. In the case where the grip casing part is used to support a video camera with a still camera, the still camera part is housed in the grip casing part, and the grip casing part has an imaging optical system for the still camera on its front surface. The system is opened so that it faces the same field of view as the imaging optical system for the video camera, and the film loaded into the still camera section is loaded so that the supplied cartridge and the winding roll are rotated in opposite directions. The light-receiving surface of the film is arranged perpendicular to the still camera imaging optical system.

In this specification, the term "video camera with still camera" refers to whether the still camera section is integrated into the video camera section, whether the two are separable, or if they are separable, each can be used as a single unit. It shall be interpreted in a broad sense to include photographic devices having both a still camera function and a video camera function, regardless of whether or not the term is a camera function.

DESCRIPTION OF EMBODIMENTS Next, embodiments of a video camera with still camera according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, the present invention is illustrated in the so-called 8
