Abstract
PURPOSE:To prevent the operation mistake for the outdoor field collection, by taking in assuredly the input signal regardless of the selection switch in case the input signal is from just one system and then delivering the signal of the system designated by the selection switch in the case of the two systems respectively. CONSTITUTION:When the input signal S1 of the line exists and with no existence of the input signal S2 of the video camera each, the signal S1 is detected by the signal detecting circuit 9 and then added to the digital switch 3. And the mobile contact 3c of the switch 3 is connected to the fixed contact 3b, and thus the analog switch circuit 4 is actuated by the signal S1 itself. Then the fixed contact 4a of the circuit 4 is connected to the mobile contact 4c to deliver the signal S1 onto the output terminal. When both signals S1 and S2 are supplied, the switch 3 is actuated by the output of the AND gate 11 which uses the output of the signal detecting circuit 9 for the input. And the signal S1 is delivered to the output of the circuit 4 in case the contact 2c of the switch 2 is identical to the fixed contact 2a; while the signal S2 is delivered to the output of the circuit 4 when the contact 2c is identical to the fixed contact 2b for selection via the switch 2.
