<p>PURPOSE:To eliminate recording paper jammed between paired rollers easily by forming a call part acting on a roller shaft on one side, while attaching a lever with a larger inner diameter than the other roller shaft diameter to the top of a roller shaft on the other, and constitution the pressure-contact and separation of the roller pair so as to be performed by operation of this lever. CONSTITUTION:A cam part 31 shifts and displaces a pressure roller shaft through turning operation of a lever 32, and a clearance is formed between a driving roller 14 and a pressure roller 15. With occurrence of this clearance, removal of jammed recording paper is easily performed. At this time, since the lever 32 is attached to the top of the roller shaft in a state of being loosely inserted, detachment can be done very easily.</p> |
