Abstract

The case of an image sensing apparatus such as a video camera is simplified by reducing the number of parts provided on the surface of the apparatus without eliminating a remote-control function. The video camera is formed to have an opening for introducing sensed light from a subject and first remote-control signal light which remotely controls the video camera into the interior of the camera case, and for projecting second remote-control signal light, by which the video camera remotely controls an external apparatus, to the exterior of the camera. After the first remote-control signal light is introduced into the interior of the camera case via the opening, the light is received by a remote-control light-receiving element and the second remote-control signal light is projected to the exterior of the camera case via the opening. As a result, the first remote-control signal light and the second remote-control signal light can be made to traverse the same optical path as that of the sensed light from the subject. This makes it unnecessary to provide the surface of the camera case with a window for the first remote-control signal light and second remote-control signal light.
