And a photometric sensor window 3b, and a colorimetric or white balance sensor window 3c. The front surface is covered by a single protective member 4 such as a protective glass. This is because the optical environment of each optical system is made as equal as possible to improve the accuracy of photometry and colorimetry, and it is suitable for cleaning the optical system, dustproofing, and the like.

On the front of the camera body, a finder window 5, an eject button 6 for unlocking and opening a video floppy holder for attaching and detaching a video floppy to be described later to and from the camera body, an LED 7 for displaying a self-timer operation, A strobe issuing window 8 and the like are provided.

When viewed from the top, an operation including a video floppy holder 9, a shutter release button 10, a plurality of operation buttons for setting various modes, and a switch, which can be freely opened and closed so that the video floppy can be attached to and detached from the camera body. A section 11 and a switch 12 for switching between macro shooting and normal shooting are provided.

As shown in FIG. 2, a video output terminal VO for outputting a reproduced video signal obtained by reproducing the recorded information on the video floppy with the electronic camera is formed on the rear surface of the camera body. Battery storage section 13 is formed,
In the state where the battery B is stored, by closing the battery cover 14, the state where the battery B is stored in the battery storage unit 13 can be maintained. 5a is a finder.

Next, the connection relationship between the camera of the present invention, an AC adapter, a display, and the like will be described with reference to FIG. In the figure, reference numeral 15 denotes a power supply adapter for converting an AC power supply of a power line into a predetermined DC power supply, a DC output terminal 15a connectable to an AC coupler described later, and a charger for charging the battery B. Also serves as. The AC adapter 15 has a battery mounting portion 15b for charging the battery B, and also has a function as a charger.

Reference numeral 16 denotes an electric contact provided at the same position as the battery B when the power is supplied from the AC adapter to the camera when the camera is used. The electric contacts 16a and 16b are provided at the same position as the battery B. An attachment 17 connected to the terminal is an AC coupler connected to the attachment 16 by a cord 18 and connected to a DC output terminal 15a of the AC adapter 15 via a power input terminal 17a.

Therefore, as for the power supply line, the DC output from the AC adapter 15 is supplied from the power supply electrode terminal in the battery housing 13 to the camera via the AC coupler 17 and the attachment 16.

On the other hand, the attachment 16 has a video signal output cord 19 that can be connected to the video output terminal VO at the rear of the camera body.
The code 19 passes through the attachment 16 and the code 18, is supplied to the AC coupler 17, and is output from the video output terminals 17 b and 17 c disposed on the AC coupler 17.
