[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal board, 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 type, such as a video camera integrated VTR, have been designed to reduce power consumption and to be integrated at a high density as a whole, and as a result, can be made compact and lightweight. 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, for example, when going out, there is a possibility that a valuable 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, it is possible to record by simply arranging the dry battery without waiting for the battery to be charged, which is practically convenient.

However, if a space for accommodating the dry battery is provided in the main body of the video camera integrated VTR and the power source is 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 for batteries or batteries to the outside of the case of the main body can be considered. In this way, just replace the power supply 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 supply 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 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 that of battery, it may be difficult to drive the VTR main body with video camera practically due to the voltage drop. In the body type VTR main body, it is necessary to design in consideration of the voltage rise at the time of no load so that the video camera integrated type VTR main body is not damaged even when there is no load.

Therefore, in the case of different VTR bodies with integrated video cameras as described above, when the method of attaching the power supply unit is made common, the power supply unit can be easily switched, so that such consideration is not taken. By accidentally connecting the power unit of the dry battery to the integrated VTR body,
The main body may be damaged by the increase in the power supply voltage.
Furthermore, not only the video camera integrated VTR body but also the power supply unit containing the dry battery or the power supply unit of the power adapter may be accidentally connected to the charger, in which case the dry battery may cause liquid leakage or other accidents. 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 attachment to an electronic equipment body such as a video camera integrated VTR body, and to easily and easily install the electronic equipment body as necessary. The purpose is to propose a terminal board that can be replaced with a power source and the power source can be switched.
