Optical rotary connector device

Abstract

Abstract PURPOSE:To transmit and receive simultaneously and continuously an optical signal to and from each fiber core by fitting each fiber core in a multicore optical fiber cable, to a rotary plate which rotates on its revolving shaft together with a rotating body. CONSTITUTION:When a drum 1 rotates, a multicore optical fiber cable 5 is fed out and wound from the drum 1, and when each fiber core 5a-5d rotates together with the drum 1, a rotary plate 12 and a rotary member 15 synchronize with the drum 1 and rotate in the same direction. Accordingly, a relative position relation between each fiber core 5a-5d and each turning member 15 is not varied, and when the drum 1 is rotating, an output optical signal from the first fiber core 5a is focused by a focusing rod lens 20 of the rotary member 15 in the vicinity of the rotary plate, passes successively through a hole 15b of other turning member 15, inputted to a focusing rod lens 21a of a guide member 21 in the turning member 15 of the other end of a frame body 11, guided by an optical fiber 21c and other focusing rod lens 21b, led onto a revolving shaft of the rotary plate 12, and fetched to the outside of the drum 1 by a fiber core 6a of a fiber cable 6.
