が悪いという問題点があつた。Configuration of Conventional Example and Its Problems Conventionally, as a video camera using an image pickup tube, as shown in FIG. 1, an optical axis (2) of a taking lens (1) for taking an image of a subject and an image pickup tube (3) are provided. It is common that the optical axis (4) and the optical axis (4) are arranged in a straight line, but such an arrangement has a problem that the length in the optical axis direction becomes long. Therefore, as a means for shortening the length in the optical axis direction, as shown in FIG. 2, the optical axis (6) of the taking lens (5) and the optical axis (8) of the image pickup tube (7) are reflected by a reflecting mirror. (9) is used to make them substantially orthogonal, and the image pickup tube (7) is connected to the hand grip (1
The one housed inside (0) has been put to practical use. However, even if the optical axis is bent about 90 ° in this way, the length of the taking lens in the optical axis direction (horizontal direction) is shortened, but the length in the vertical direction is not shortened. Therefore, the camera case used for storing and transporting the video camera is inevitably large in size, resulting in poor portability.
発明の目的 本発明は上記従来の欠点を解消するもので、携帯性がよ
くしかも使い勝手の良いビデオカメラを提供することを
目的とする。An object of the present invention is to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide a video camera having good portability and usability.

する構成としたものである。To achieve the above object, a video camera of the present invention includes a taking lens for taking an image of a subject, a photoelectric conversion unit for converting an optical image passing through the taking lens into an electric signal, and an optical axis of the taking lens. An optical axis bending means for bending approximately 180 ° is provided, and the taking lens and the photoelectric conversion means are arranged in parallel.

Furthermore, the exterior part of the photoelectric conversion element can be used as a hand grip, and since this hand grip is parallel to the shooting lens, it can hold the video camera in a stable manner, resulting in good operability and reduced blurring of the shooting screen. it can.

FIG. 3 is a schematic configuration diagram of a video camera. A photographing lens (12) for photographing a subject (19) is attached to a video camera body (11), and an optical axis (13) of the photographing lens (12) is a video. It is bent 90 degrees by the half mirror (14) built into the camera body (11), passes through the relay lens unit (15) and is further bent 90 degrees by the surface reflection mirror (16), Image pickup tube (1
Reach 7). That is, the taking lens (12) and the image pickup tube (17) are arranged side by side, and the photoelectric conversion surface (18) of the image pickup tube (17) faces the side opposite to the subject (19) side. In addition, part of the light that has passed through the taking lens (12) passes through the half mirror (14) and reaches the finder lens system (20), and the image is taken by the taking lens (12) by looking into the eyepiece (21). Can be confirmed.

The exterior part (22) of the image pickup tube (17) serves as a hand grip, and the taking lens (12) is provided on the top surface of the exterior part (22). The zoom control switch is equipped with a switch group (23) such as a VTR control switch.

Further, in the above-mentioned embodiment, since the optical viewfinder is used as the finder, the mirror on the side of the taking lens (12) is the half mirror (14). However, a total reflection mirror is used as this mirror and a small CRT is built in as the finder. The electronic viewfinder described above may be used.
