PURPOSE:To bring a sufficient tension effect into full play over the whole paper size, by installing plural tension members in contact with an upper surface of paper, in a carry-in port of a stack part. CONSTITUTION:When both side plates 26 and 26 move, for example, paper size in use is shifted from maximum width to minimum one, during this shifting, each upper end of these side plates 26 and 26 comes into contact with each tip corner part of tension members 90a and 90b. However, since these tension members 90a and 90b are pivotally attached to a shaft 9a, these members 90a and 90b move upward whereby movements of these side plates 26 and 26 are in no case hinders. In a feed belt 35, there is provided with a roller which is pressed to this belt 35 and driven in addition to a double-feed preventing roller 38, so that conveying force is giveable to the extent of the rear end of paper even to such one, the smallest in length, in the service paper size and, what is more, the paper is surely deliverable to a regist roller 104. |
