B Summary of the Invention The present invention provides a power supply case that is fixed to the main body of an electronic device by providing a concave and convex portion on the surface of the power supply case based on the type of power supply to be stored in the power supply case. This prevents the power supply from being accidentally connected to the main body of the electronic device.

C. Prior Art In recent years, this type of electronic equipment, such as a video camera - type VT
In addition to reducing power consumption, R has been designed to be highly integrated as a whole, resulting in a compact, lightweight and highly portable video camera that can record for long periods of time even with a small battery capacity. It is possible to obtain a camera-integrated VTR.

D Problems to be Solved by the Invention In such a video camera-integrated VTR, if the battery is inadvertently consumed when the user is out, for example, there is a risk that valuable scenes may not be recorded.

In such cases, if you could easily switch the power source from a battery to a dry cell, you could record without having to wait for the battery to charge, just by arranging the dry cell.
It is convenient in practice.

However, if a space for storing batteries was provided in the main body of a VTR with an integrated video camera so that the power source could be easily switched from the battery to the dry battery, the VTR with an integrated video camera
There is a problem in that the overall size cannot be avoided.

In order to solve this problem, for example, a power supply unit containing a battery and a power supply unit containing a dry cell battery are provided separately from the main body of a VTR with an integrated video camera.
A possible method is to attach a battery or dry cell power supply unit to the outside of the case of the video camera-integrated VTR main body to switch the power source as necessary.

In this way, you can switch the power supply by simply replacing the power supply unit.
TR can be obtained.

Furthermore, if this installation method is commonly used for the power supply unit connected to the video camera integrated VTR, such as a power adapter, the installation of each type of power supply unit in the video camera integrated VTR body can be done separately. It becomes possible to use it in common.

In addition, if this type of installation method is used in common for different models of video camera integrated VTRs, one type of power supply unit can be used in common among all video camera integrated VTRs, and the power supply for each model can be used in common. It is convenient in practice because there is no need to prepare a unit.

However, when using dry batteries, unless the power supply voltage during no-load is higher than when using batteries, it may be difficult to actually drive a VTR with an integrated video camera due to voltage drop, In order to prevent the video camera integrated VTR main body from being damaged even when there is no load, it is necessary to design a video camera integrated VTR main body that takes into consideration the voltage rise during no load.

Therefore, as mentioned above, if the power supply unit installation method is standardized among different video camera integrated VTR bodies, the power supply unit can be easily switched. If a dry battery power supply unit is mistakenly connected to the main body, there is a risk that the video camera integrated VTR main body will be damaged due to an increase in the power supply voltage.

Furthermore, there is a risk of connecting not only the main unit of the video camera integrated VTR but also the power supply unit with dry batteries stored in the charger or the power supply unit of the power adapter, and in this case, accidents such as dry cell battery leakage may occur. There was a problem that the charger could be damaged.

The present invention has been made in consideration of the above points, and can effectively avoid the possibility of being mistakenly attached to an electronic device body such as a video camera integrated VTR body, and can also be easily attached to an electronic device body as necessary. The purpose is to propose a power supply case for batteries, dry batteries, etc. that can be attached and switched to power sources.
