A main body of a camera accommodates a light receiving part. The main body has a flat bottom surface. A support is aligned with the main body in a left-right direction, and supports the main body in such a manner that an orientation of the light receiving part can be controlled in a vertical direction. A bottom surface of the support is located on a common plane on which a bottom surface of the main body is also located. The bottom surface of the support can be attached to and detached from a stand member which is mounted to a display device. This camera promises enhanced stability of mounting of the camera to an edge of a display device.
