Abstract

PURPOSE:To prevent photosensitive bodies and the like previously from injury caused by jam-phenomenon by providing a jam-detection part between conveying means near a record picture forming part for detecting the jam-phenomenon rapidly. CONSTITUTION:When a continuous paper 4 is cut or comes off from an upper tractor 6, the continuous paper 4 is loosened between the upper tractor 6 and a lower tractor 5, and a buffer 9 and an arm 20 are turned round a shaft 19 in the direction of an arrow 23 as alternate long and short dashes lines show. Therefore, the effect is determined as a jam-phenomenon on the basis of the change of the output of a potentiometer 24. Meanwhile, when fixing rollers 121 and 122 are speeded excessively, the buffer 9 and the arm 20 are turned in the reverse direction of the arrow 23. In this case, the effect is also determined and detected as the jam-phenomenon on the basis of the change of the output of the potentiometer 24. When the jam-phenomenon is determined, the continuous paper 4 is immediately stopped, and guide plates 101 and 102 are operated to separate from a photosensitive drum 1.
