<p>PURPOSE:To prevent slanted paper feeding, correcting slant of paper side of any regular size with a pair of ribs by forming specified ribs on an outer side wall surface of a curved part of an inverted guide, and enlargening the height of the ribs responding to the regular size of the paper. CONSTITUTION:The inverted guide 4 is stretched in parallel along a carrying direction on the outer side wall surface of the curved part 11, and a multiple number of ribs 16, 17 and so on, which protrude to the inner side are formed. Then the height of those ribs are gradually enlarge so that they are symmetrical from a center O of the width of the paper and at the same time responding to the standard size of the paper. Therefore, when for example, paper of A4 size is fed inverted, although there is a tendecy to be slanted compared to paper feeding in one direction, slanted paper feeding can be prevented because both sides of the paper P can be restricted by the ribs 18 and 19. Thus, the slanting of paper side of any regular size of paper can by corrected by a pair of ribs, and the slanted paper feeding can be prevented.</p> |
