Description

The present invention relates to an image pickup device such as a digital video camera for business use, and more particularly to an image pickup device having a plurality of external connection terminals.

For professional digital video cameras, etc., the camera body is carried on the shoulder while the cable is connected for shooting, so the connector is connected to the camera so that the connector to which the cable is connected is not damaged. Most of them are located on the back side of the main body.

However, in recent years, professional digital video cameras have become more multifunctional, and the number of connectors is increasing due to the provision of connectors for high-speed communication, connectors for IP communication, and the like on the camera body. Therefore, not all the connectors can be arranged on the back side of the camera body, and some connectors are arranged on the side surface of the camera body (Patent Document 1).

Japanese Unexamined Patent Publication No. 2007-53426

However, if the number of connectors increases due to the further multi-functionalization of the camera, if the connector is placed on the side of the camera body, the connector may be pulled out due to the cable being caught when moving with the camera body carried on the shoulder. Is likely to occur.

On the other hand, if all the connectors are arranged on the back surface of the camera body, the size of the camera body in the width direction is further increased, which makes the shape unsuitable for a shoulder-mounted professional digital video camera.

Therefore, the present invention aims to reduce the thickness of the device main body of the image pickup apparatus in the width direction, and reduces the pluggability of the cable to the external connection terminals even when a plurality of external connection terminals are arranged on the side surface of the device main body in the width direction. It provides the technology to prevent the cable from getting caught and the connector from coming off.

In order to achieve the above object, the image pickup apparatus according to claim 1 has a device main body in which a lens portion is detachably mounted on the front surface and a battery unit detachably mounted on the back surface, and a front surface of the device main body.

The closer it is to the front surface, the more it is tilted toward the front surface side so as to be away from the device body, and the plurality of inclined surfaces do not overlap each other when viewed from the left side surface side, and the back surface side of the device body. It is characterized in that it is arranged so that at least a part of it overlaps with each other when viewed from the viewpoint.

According to the present invention, while trying to reduce the thickness of the device main body of the image pickup device in the width direction, even when a plurality of external connection terminals are arranged on the side surface in the width direction of the device main body, the insertability of the cable to the external connection terminals is reduced. It is possible to prevent the cable from getting caught and the connector from coming off.
