Abstract
An image-forming machine comprising a conveying passage for conveying a sheet material through a transfer zone, a first and a second feed system for feeding the sheet material to the conveying passage, a first feed passage for conducting the sheet material delivered from the first feed system to the conveying passage, a second feed passage for conducting the sheet material delivered from the second feed system to the conveying passage, and a first and a second opening-closing member for opening and closing the first and second feed passages. Various improvements are made on the first and second opening-closing members. Further provided are an improvement for suppressing noises, an improvement for preventing folding of a sheet material, an improvement for easily switching over to a mode of forming an image on both surfaces of a sheet material, an improvement for accurately conducting the sheet material from a reversal holding portion to a return passage, and an improvement for positioning the sheet material received in the receiving-refeeding portion at a predetermined widthwise position in the above and other types of image-forming machines.
