<p>PURPOSE:To prevent a head from being mistakenly connected by transmitting an identification signal from a camera control unit to a television camera head and identifying whether the identification signal specifies a self television camera head. CONSTITUTION:An identification signal generator 112 is provided which generates the identification signal to identify a television camera corresponding to the side of the camera control unit CCU 11, and the generator 112 transmits its generating identification signal to the head 12 through a camera cable 13. An identification signal detection circuit 123 is provided on the side of the head 12, and detects the identification signal from the CCU 11. When the identification signal specifies the television camera, a power breaker 122 is set to an off state. If not, the power breaker 122 is set to an on state. Namely, only when the television camera is specified, power from the CCU 11 is supplied to a power source circuit 121. Accordingly, if the head 12 is connected to a difference CCU, power source is not supplied to the powre source circuit 121, whereby the head 12 is not damaged.</p> |
