[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply case and is suitable for application to electronic equipment such as a video camera integrated video tape recorder (video camera integrated VTR).

[0003]

2. Description of the Related Art In recent years, electronic devices of this kind, such as a video camera integrated VTR, have been designed to reduce power consumption and to be integrated with high density as a whole, resulting in a small size and a light weight. A VTR with a built-in video camera, which has good portability and can record video for a long time even with a small capacity battery, has been provided.

[0004]

In such a VTR with a built-in video camera, if the battery is inadvertently consumed when going out, there is a possibility that a precious scene cannot be recorded. In such a case, if the power source can be easily switched from a battery to a dry battery and used, recording can be performed simply by arranging the dry battery without waiting for the battery to be charged, which is practically convenient.

However, if a space for accommodating the dry batteries is provided in the video camera integrated VTR main body so that the power source can be easily switched from battery to dry battery, there is an unavoidable problem that the whole video camera integrated VTR becomes large. .

In order to solve this problem, for example, a power supply unit for storing batteries and a power supply unit for storing dry batteries are provided separately from the video camera integrated VTR main body, and if necessary, the video camera integrated VTR. A method of switching the power supply by attaching a power supply unit of battery or dry battery to the outside of the case of the main body can be considered. In this way, just replace the power unit,
It is possible to obtain a small video camera integrated VTR capable of switching the power supply.

Further, if such a mounting method is commonly used for a power supply unit connected to a video camera integrated VTR such as a power adapter, a mounting portion for each type of power supply unit in the video camera integrated VTR main body. Can be used in common. In addition, a video camera integrated VT of a different model with such a mounting method is used.
If it is commonly used for R, one type of power supply unit can be commonly used for each video camera integrated type VTR, and it is not necessary to prepare a power supply unit for each model, which is practically convenient.

However, when using a dry battery,
Unless the power supply voltage under no load is higher than in the case of battery, it may be difficult to drive the video camera integrated VTR main body due to the voltage drop in practice. In the body type VTR main body, it is necessary to design in consideration of the voltage rise under the no load so that the video camera integrated type VTR main body is not damaged even under the no load.

Therefore, in the VTR main body with different video cameras as described above, when the mounting method of the power source unit is made common, the power source unit can be easily switched, so that such consideration is not taken. By connecting the power unit of the dry battery to the integrated VTR body by mistake,
The main body may be damaged due to a rise in the power supply voltage.
Furthermore, not only the video camera integrated VTR body, but also the charger may accidentally connect the power supply unit containing the dry battery or the power supply unit of the power adapter. In this case, the dry battery may cause liquid leakage. There was a problem that the charger was damaged.

The present invention has been made in consideration of the above points, and it is possible to effectively avoid erroneous mounting and to easily switch the power source by attaching it to the main body of an electronic device, a dry battery, etc. The power supply case is proposed.
