Abstract

PURPOSE: To accomplish the level detection of high accuracy by enlarging the displacement of a separating pawl with the use of a lever mechanism and to stop the paper feeding operation and display it in an operating panel in case recording paper is out of engagement with the separating pawl.
CONSTITUTION: The recording paper placed on a carriage 31 is elevated by carriage elevating means into abutment contact with separating pawls 32 and 43 which are positioned at the front edge corners in the paper feeding direction of the uppermost recording paper. As a result, the leading end 34a of a recording paper level detecting arm 34 is rocked in an enlarged scale to provide a shield between a light emitting element 35 and a light receiving element 36 so that a level is detected to stop the carriage. Since, at this time, the uppermost recording paper is abutting against paper feed rollers 52 and 60 and is supplied with desired pressure therefrom, it is under such a condition as to be fed. In case the position of the recording paper is so deteriorated that the paper and the separating pawl 32 fail to engage thereby to effect the excessive rise of the rollers 52 and 60, a switch S3 for detecting the excessive rise of the rollers is operated to stop the rise of the carriage.
