Abstract
An optical connector cleaning tool includes a cylindrical connecting portion to which an optical connector is connected, a cleaning unit configured to guide a cleaning thread to a coupling end face of an optical connector plug, and an optical unit having an optical path reaching the optical connector plug. The optical unit includes a lens arranged in a position facing the coupling end face to form one end portion of an optical system, and having a missing portion extending in an optical-axis direction, and an image sensor positioned at the other end of the optical system. The cleaning unit includes a rod-like cleaning tip having a thread passage through which the cleaning thread passes. The cleaning tip is inserted into a hollow portion of the lens having the missing portion extending in the optical-axis direction, such that the cleaning tip is movable in a longitudinal direction thereof.
