Image-forming apparatus |
摘要 |
The present invention provides an apparatus for forming images on a substrate, using a belt-like medium which is moved past a number of precessing stations. The apparatus has at least two sections in which the belt-like medium can be driven at different speeds by different drive rollers at the same time. A buffer unit between the two sections compensates for the belt length shortage and/or surplus arising from the speed difference. The buffer unit consists of two parallel freely rotatable rollers secured to the ends of a rotatable frame.
