  Conventional video camera devices for business use include a camera body and VTR unit integrated, a camera body and VTR unit connected by a signal cable, or a camera body and VTR unit that can be separated and combined. And a dockable video camera device configured as described above. In video camera devices, an air cooling fan is generally provided in the upper part of the camera body, and the air cooling fan forcibly exhausts the heat generated inside the housing to the outside and adopts a method of air cooling. In addition, there are those that naturally cool through a heat sink attached to the side plate of the video camera main body, and those that radiate heat by combining an air cooling fan and a heat sink.

  In a video camera device that dissipates heat using an air cooling fan, the heat generated by the air cooling fan provided at the top is released from the top, and the heat of the photographer's hand holding the grip provided at the top of the camera body is generated.

  However, the conventional dockable video camera device usually has a configuration in which the camera body and the recording device (VTR unit) can be separated and combined, and it is necessary to dissipate heat by providing an individual heat dissipating mechanism. The storage capacity of the circuit board stored in the body tends to be narrowed, and the circuit board is arranged in a direction orthogonal to the optical axis, the number of circuit boards tends to increase, and the cost is high. There was a trend. The conventional dockable type video camera device has a structure that can be separated and combined at the front and rear, and such a separation structure causes the above-mentioned problems. It has been desired to simplify the integrated structure common to each other and reduce the weight by reducing the number of circuit boards.

In addition, the airflow passage for heat dissipation uses a material with high thermal conductivity on the side where the electronic component contacts, for example, magnesium, aluminum, copper, etc., and the material on the opposite side has a low thermal conductivity, For example, resin materials such as ABS and PC are used, and there are disadvantages that the structure is complicated, the weight is increased, and the cost is increased.

  In such a conventional dockable video camera device, it is necessary to provide a heat dissipation structure in the camera body and also to provide a separate heat dissipation structure in the VTR unit (peripheral device), and the heat dissipation structure provided in both increases the weight, Due to the high cost, a video camera device that has a novel dockable structure and that can be simplified and reduced in weight by sharing the heat dissipation structure has been desired.
