Abstract

PURPOSE: To reduce the entire monitoring time through a simple constitution by setting the rotary center at the position where the beam coming in from the side wall surface is reflected backward and at the position distant away from the optical center axis of the lens and the pickup tube.
CONSTITUTION: Reflector 24 is installed in a rotatable way inside TV camera case 21, and furthermore TV camera lens 26 and pickup tube 27 are provided at the back of reflector 24. In this case, the monitor window is provided at both front edge surface 21a and side wall surface 21b of case 21 each, and reflector 24 is located at the position where the beam coming in from monitor window 23 of surface 21b is reflected backward. And the rotary center is positioned distant away from optical center axis 28 of lens 26 and tube 27. As a result, the underwater monitoring time can be reduced as a whole through a simple constitution.
