Abstract
PURPOSE: To facilitate an easy process for a continuous paper, by giving a gap between the both pressure rollers at the initial setting of the recording paper and when the paper jam is detected, and then giving a fine adjustment to the pressure distribution between the both rollers.
CONSTITUTION: When the paper jam occurs, the recording paper 6 has lines. And the a certain engagment plate 53 is not restricted by the paper 6 any more to touch the electrode plate 56 and thus transmit the alarm signal. With this alarm signal, the eccentric cams 15 and 15' are turned in the same way as the initial setting of the paper to cause a gap between the pressure rollers 7 and 8. As a result, the jammed paper can be removed easily. The oblique shift of the paper 6 is detected by the oblique shift sensor 19 to deliver the signal. Then the eccentric cams 17 and 17' provided with a shift of 180° given to the phase have turns according to the output signal in the same direction and by a fixed angle. As a result, arms 11 and 11' rock in the opposite directions to each other, and the spring force is controlled for the springs 16 and 16' to give a fine control to the pressure between the rollers 7 and 8. Thus the oblique shift of the recording paper is corrected easily.
