OPTICAL SPATIAL TRANSMISSION DEVICE

摘要

PURPOSE:To easily and surely adjust the emitting direction of a light beam as to a two-way optical spatial transmission device which transfers the light beam and transfers a desired information signal between a desired transmission object and the device. CONSTITUTION:A direction adjusting mechanism 20 is formed so that the direction of an optical system 17 can be varied by pivotally supporting the optical system 17 by turning shafts 23a, 23b, 25a and 25b near the center of gravity is formed and housed in a housing 13 together with the optical system 17 and a signal processing system 14.
