CONTACTLESS COUPLER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a contactless coupler system which can prevent dirt from being deposited on light emission and reception surfaces. SOLUTION: This contactless coupler system comprises an outlet box 1 and an outlet 2 inserted into the outlet box 1, prevents dirt from being deposited on the light reception and emission surfaces of a light receiving element 16 and a light emitting element 17 by holding the outlet 2 inside the outlet box 1 so that it faces obliquely up and arranging the light receiving element 16 and light emitting element 17 above the internal wall of an insertion path 14 where the outlet 2 is inserted, and wipes and cleans those light reception and emission surfaces by a cleaning part 23 when the outlet 2 is inserted.
