PROBLEM TO BE SOLVED: To drive a fleece cleaning a fixing heat roller by simple and compact constitution without requiring a dedicated driving source by providing a device with a unidirectional clutch mechanism intermittently driving a reel taking up the fleece in a take-up direction by utilizing the rotation of the fixing heat roller. SOLUTION: When an upper heat roller 22a is rotated counterclockwise in an upper fleece unit, a first lever 235 is turned counterclockwise every time that the tip thereof is engaged with the D-cut part 239-1 of a shaft 239 and a gear 234 is intermittently turned. In accordance with it, a gear 233 is intermittently turned clockwise. A second lever 232 is intermittently turned clockwise every time that the tip thereof is engaged with the D-cut part 233-1 of the gear 233. Then, the unidirectional clutch 230 is intermittently turned so as to intermittently turn the take-up reel of the fleece. Thus, the rotation of the roller 22a is drastically reduced and intermittently transmitted to the take-up reel. A lower fleece unit is provided with the same constitution. |
