Abstract

PURPOSE: To prevent occurrence of jam and accurately notify the location of jamming, by detecting misfeed, oblique travel, and standstill of recording member by means of specified sensors, and stopping feed of recording member.
CONSTITUTION: When recording member detection signals by sensors 36-1W36-3 provided side by side at right angle to the feeding direction in the vicinity of the recording member feeding part are logically processed in a circuit containing gates, FF, and timer circuits, the amount of oblique travel exceeding the specified amount corresponding to the size is detected, and occurrence of jam due to oblique travel is preliminarily warned by illumination of lamp and other means. By standstill of recording member in the sensors 36-1W36-3 and detection of recording member by sensors provided ahead of these sensors 36-1W36-3 in the conveying direction, jam in other place may be detected, so that occurrence of jam may be prevented and that location of jamming may be clearly notified.
