地検出装置。In a television camera that is inserted into a pipe to take pictures of the inside of the pipe and projects the images on a cathode ray tube to inspect the inside of the pipe, the camera body supported by a protective cover is rotatable by remote control, and a The end of a side-viewing mirror is pivotally supported near the edge that covers the front surface of the lens of the stored camera, and the side-viewing mirror is rotatable by remote control, and a light emitting body rotates integrally with the camera body. An azimuth detector consisting of a light emitter and a photoreceptor is provided, and an azimuth detection pattern having a weight portion at the bottom is rotatably provided between the light emitter and the photoreceptor. An inspection inside a cable conduit, characterized by having an orientation detection device that forms a number of divisions with different light transmittances and thereby detects the orientation of a camera body with respect to the top and bottom of the conduit based on the degree of light received by a photoreceptor. Top and bottom detection device for TV cameras.
