<p>PURPOSE:To reduce the dispersion of the frictional force between a card and a paper feeding roller by installing a parallelogram-shaped link mechanism whose one edge is held onto a cover body and the other edge is held onto a pressing body in vertically turnable ways. CONSTITUTION:When cards 2 are successively sent, the number of cards 2 in a card storing part 4 reduces. Though a parallelogram-shaped link mechanism 8 is turned by this change, a pressing body 9 held onto the parallelogram-shaped link mechanism 8 at two points on the shafts 14 and 15 turns relatively for the links 12 and 13, and shifts parallel to the card 2. Since the pressing body 9 has a flat surface 16, a part of the flat surface 16 is positioned directly over a paper feeding roller 7. Therefore, the card 2 can be pressed always directly over the paper feeding roller 7 by the flat surface 16, independently of the change of the number of cards 2, and the dispersion of the frictional force between the card 2 and the paper feeding roller 7 can be reduced.</p> |
