<p>PURPOSE:To stably obtain the resist performance of high accuracy by providing a stopper member which is protruded into a carrying path when follower rolls are separated, and on the other hand, retracted from the carrying path when both rolls are brought into contact with each other and driven, in the vicinity of the downstream side of a pair of resist rolls. CONSTITUTION:On the downstream side of a pair of resist rolls 9 which can be brought into contact with each other and can be separated from each other, a stopper member 12 which can make frequent appearance to a form carrying path 13 is provided, and at the time of driving a sheet 2 against the stopper member 12, the pair of rolls 9 are separated, and at the time of driving the pair of rolls 9 and feeding the sheet 2 again, the stopper 12 is drawn back from the form carrying path 13. In such a manner, at the time of feeding the sheet into a resist part, since the pair of rolls 9 are separated, and also, the stopper member 12 closes the sheet carrying path 13, the sheet 2 can always be fed to a prescribed position irrespective of thickness of paper and its curl, and also, at the time of carrying the sheet 2 again, the sheet 2 is gripped by the pair of rolls 9, and thereafter, the stopper member 12 is allowed to escape from the sheet carrying path 13, therefore, the shift of the sheet does not occur and the resist performance can be surely obtained.</p> |
