<p>PURPOSE:To simplify the constitution with reduction of the installing space and then realize a light weight of the apparatus, by advancing and retreating the support plate attached with the head pinch roller by means of the motor. CONSTITUTION:Pinch roller lever 22 containing head 24 and pinch roller 20 is provided to heat pinch roller support plate 18. Plate 18 can be slid by a pair of guides 25 and 26 consisting of the guide pin and the guid hole. At the same time, engaging component 16 comprising the rack is installed to plate 18 to be engaged with pinion gear 14 of output axle 13 of motor 12. With the clockwise turning of motor 12, plate 18 is changed from the retreated position to the advanced position by gear 14 and component 16. In this way, the constitution can be simplfied with reduction of the installing space, and a comparatively light weight is secured for the pinch roller support mechanism.</p> |
