PURPOSE:To enable to change over to a paper-setting condition by a simple construction and with small space, by a method wherein a roller-supporting plate is provided with a tendency of rotating in one direction under gravity, and a restricting means for restricting the rotating angle of plate is provided. CONSTITUTION:When a knob 17 is pulled leftward, a release lever 16 is rotated, whereby a rotary shaft 3 is also rotated through arm members 20, 19, and a guide plate 5 and a bracket 7 are separated from a platen 4. Simultaneously, pressure rollers supported on the bracket 7 through a pivotal shaft 9 and the roller-supporting plate 10 is also separated from the platen 4 due to the tendency of rotating under gravity, and due to a gap between a roller shaft 11 and a notched part 7a of the bracket 7 and an angular displacement of the bracket 7, gaps (c), (b) are formed between the platen 4 and the rollers 13, 14, resulting in the paper-setting condition. The condition is maintained by the positional relationship between an engaging part 16a and a toggle spring 18. On the other hand, when the knob 17 is turned to the right side, a paper-feeding condition is obtained. |
