PURPOSE:To enable stable automatic paper feed even if there is irregularity in the operational timing of a microswitch, by providing a delay circuit between the microswitch detecting the start indication of paper feed and a paper feed mechanism. CONSTITUTION:When a lever 18 is fallen to the direction shown by the arrow B, a bale roller 15 moves to the direction shown by the arrow C to be brought to an open state and a microswitch 19 is turned off from an ON-state. When said microswitch 19 is turned OFF, a delay circuit is operated and, after a definite time (the time before the bale roller 15 is perfectly opened) was elapsed, a paper feed mechanism is operated to rotate a platen 11. Next, when the lever 18 is returned, the bale roller 15 is returned to the original position and the microswitch 19 is turned ON from an OFF-state. When said microswitch 19 is turned ON, the delay circuit is operated and, after a definite time (the time before the leading end part of paper 1 is pressed by the bale roller 15 brought to a closed state) is elapsed, the paper feed mechanism is operated and the platen 11 is slightly rotated reversely. |
