<p>PURPOSE:To detect the positional azimuth of a camera instantaneously by detecting the horizontal and vertical directions of a rotary board mounting the camera and displaying the rotation position of the rotary board in accordance with a detected output signal. CONSTITUTION:The rotary board 23 is controlled by a control signal from a remote control part 24 through a cable 32 and an object in the azimuth is photographed by the camera 21 and the picture of the object can be observed by a monitor receiver 22. An electric signal corresponding to the rotation of the rotary board 23 can be detected by detecting elements 41, 43. Discrimination parts 49, 51 discriminate the positional azimuth of the rotary board 23 by an electric signal from detecting elements 41, 42 which define the respective positional relation between magnetic bodies 42, 44 and the detecting elements 41, 42 and display the discriminated results on display elements 50, 52. Thus, the positional azimuth of the camera 21 set up on the rotary board 23 can be instantaneously discriminated by the display of a display device.</p> |
