Abstract

PURPOSE:To enable the running at a narrow path and to improve the S/N of a video signal, by providing a mechanism which attaches or detaches flexible optical system to the running path of a moving body, and separating the moving body and an image formation part of a camera. CONSTITUTION:A moving body 1 is suspended on a trolley chain 9 fitted to a guide rail 2 having a bag-shaped section with cut slit at the lower end by means of hanger 5 and runs on the rail 2. The chain 9 gears with a sprocket 12 of a chain drive mechanism 11 and is located within the rail 2. A cable 4 connected to the moving body 1 is drawn out from a cable tank 22 accompaning the forward advancing of the body 1 and coupled to a clamp 3 fixed to the chain 9 by a clamp mechanism 13.
