B Summary of the Invention The present invention provides an electronic device in which the power supply case is selectively locked by providing an uneven portion on the power supply case mounting surface according to the type of connectable power supply, thereby effectively preventing incorrect connection of the power supply. can be avoided.

C. Prior art In recent years, this type of electronic equipment, such as video camera-type VT
In addition to reducing power consumption, R is designed to be highly integrated as a whole, resulting in a compact, lightweight and highly portable video system 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 while 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 battery, you would be able to record without having to wait for the battery to charge, just by arranging a dry battery.
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 battery power to batteries, the VTR with an integrated video camera
There is an unavoidable problem in that the overall size becomes large.

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 the video camera integrated VTR.
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.

In addition, if this installation method is commonly used 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 unit for each model can be used in common. This is convenient in practice as there is no need to prepare one.

However, when using dry batteries, unless the power supply voltage under 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, so it is difficult to drive a VTR with an integrated video camera. 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, if the power supply unit installation method is made common among different video camera integrated VTR bodies as mentioned above, it will be possible to easily switch the power supply units, so it is possible to easily switch the power supply unit. If a dry battery power supply unit is mistakenly connected to the VTR, there is a risk that the video camera integrated VTR 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.
