Abstract
Abstract A remote station provided with a television camera and coupled to master station of an inter communication system is disclosed. The housing of the remote station includes at a least front panel and a window is formed through the front panel at its upper portion. An adaptor lens is engaged with the window for introducing the light from an object to be picked up at a wide angle into the housing and a pick-up tube of a television camera is disposed within the housing. A reflector is disposed within the housing between the adaptor lens and the pick-up tube so as to reflect the light from the object thereon and project thus reflected light on the pick-up tube.
