Abstract
PURPOSE: To increase the operationability of TV camera operator and to reduce the number of components and lower the power consumption, by displaying a pourality of functions by using a single display element.
CONSTITUTION: At the operation of TV camera, the power supply switch SW1 is closed, DC power supply voltage E is fed to the main body circuit 1 of TV camera. Simultaneously, for a camera in which no output is used among a plurality of TV cameras under operation, the switch SW2 for tarry of normally closed type is remained closing, then E is fed to the lamp 2 as the display element through SW1 and 2, illuminating it. Further, with the illumination of the lamp 2, the application of power supply is made and it can be known that the output of the TV camera is not in use. On the other hand, if the output video signal of a TV camera is in use, since SW2 is closed, the supply of E to the lamp 2 is interrupted, distinguishing the lamp 2. That is, a single lamp 2 plays roles of the application of power supply and the tarry display and the line can be done with one series
