Abstract

PURPOSE: To display the jamming location accurately and facilitate dejamming process, by detecting standstill of recording member through sensors porvided in specified places in a conveying route, and controlling the lighting of corresponding lamp.
CONSTITUTION: Occurrence time difference of detection outputs of recording member by three sensors provided side by side at right angle to the conveying direction in the vicinity of the recording paper feed port from a cassette is detected by a timer T4. When such time difference becomes larger than the value corresponding to the size of recording paper, the oblique travel involving high possibility of occurrence of jamming of recording paper is judged to be above the specified level, so that the timer T4 produces a high level output. As a result, FF Q11 is set, and a lamp PL1 is lit through transistor Q16 to display occurrence of jamming. Simultaneously, a lamp PL2 is caused to flicker by an oscillator 14, and the specified upper or lower stage of the cassette is indicated by flickering. Similarly, occurrence of jamming may be indicated through other sensor provided in the conveying route of the recording member.
