into the base 97. The woven base 97 is of a semi-rigid type material and is slidably
engaged in the main carrier housing 95 between a pair of side tracks 99, for
facilitating ease of replacement of the brush member 96. The brush member
96 comprises two portions, namely, 96a and 96b. The portion 96a cleans the capstan
10 and the portion 96b cleans the pinch roller 11. The tape cleaning brush 92 is carried
on the main carrier housing 95 of the capstan and pinch roller cleaning brush 91, and
cleans the cleaning surface 55 of the cleaning tape 30. The cleaning brush 92
comprises a secondary carrier housing 100 which is carried on the main carrier housing
95 by a carrier member 102 which extends from the main carrier housing 95. The main
carrier housing 95, the secondary carrier housing 100 and the carrier member 102 are
integrally injection molded. Side tracks 103 on the secondary carrier housing 100
slidably engage a relatively rigid woven base 104 of a brush member 105 of the tape
cleaning brush 92 for carrying the brush member 105 in the secondary carrier housing
100. Bristles 106 of the brush member 105 extend from, and are woven into the woven
base 104.
In the two rejections under 35 U.S.C. § 103 before us in this appeal, the
examiner concluded that it would have been obvious to one of ordinary skill in the art at
the time the invention was made to provide either the head cleaning device of Inoue or
the head cleaning device of Saito with the cleaning pad having cleaning fibers woven
