Abstract

PURPOSE:To attain a long life by preventing the lowering of the temperature of a battery and preventing the reduction of a battery voltage, even under the circumstance at a low temperature state. CONSTITUTION:Quantities of heat generated from IC 21 and 22 are transmitted through a heat transmitting material 60 to a radiating plate 65, and a battery 10 adjacent to the radiating plate 65 is heated, so that the lowering of the battery 10 temperature can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated VTR that carries a power source such as a battery.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, a camera-integrated VTR has a portion of a video lens 20 inside an outer case 40, a main portion of a video recorder, its electric circuit board 20, and a battery. The battery 10 is configured so as to be stored separately from the battery 10. In particular, the battery 10 is configured to project to the outside of the camera-integrated VTR main body, and is always easily exposed to the external environment.

[0003]

However, in the conventional camera-integrated VTR as described above, especially in an environment where the outside temperature is low, such as in a cold region, the battery exposed to the outside air cannot be captured and recorded. When the temperature drops inside, there is a drawback that the electric energy stored inside cannot be released efficiently and the voltage drops, which shortens the recording and recording time extremely.

The present invention has been made in order to solve the conventional problems, and can prevent the temperature of the battery from decreasing and maintain a constant voltage stably for a long time even in an environment of low temperature. An object is to provide a camera-integrated VTR.

[0005]

In order to achieve the above object, the camera-integrated VTR of the present invention has a structure in which the amount of heat generated from the electric circuit of the VTR is transferred to a battery via a heat conductive material. It was done.

[0006]

According to the present invention, the amount of heat generated from the electric circuit board is transmitted to the battery via the heat conducting material to prevent the temperature of the battery from lowering, thereby extending the discharge life of the battery.
