incorporated in the housing distal end of the optical connector 321 (optical connector plug)—this may be referred to below on occasion as the joining end surface 321a of the ferrule 322), the joining end surface 321a of a ferrule 322 is pressed at a portion thereof that is located between an upstream side end portion 302a and a downstream side end portion 302b in the tape feeding direction of a tape pressing surface 302 of the head portion 301. Namely, it is normal for the upstream side end surface 302a and the downstream side end surface 302b in the tape feeding direction of the tape pressing surface 302 to be placed on the outer side of the joining end surface 321a of the ferrule 322.
FIG. 38A through FIG.38D show a case in which an insertion portion 300 of an optical connector cleaning tool is inserted into a positioning housing in the form of an optical connector adapter 330, and a cleaning tape 311 that is wound around a head portion 301 of a tape pressing head 303 that is incorporated in the insertion portion 300 is pressed by the head portion 301 against the joining end surface 321a of the ferrule 322 of the optical connector 321 that is connected to the optical connector adapter 330, thereby cleaning the joining end surface 321a. In the optical connector adapter 330, the insertion portion 300 is inserted into the optical connector adapter 330 from the opposite side to the optical connector 321 that is connected to one
