Abstract
PURPOSE: To feed a sheet of paper only when it is correctly positioned, by providing a device which senses whether or not the paper is in its correct position and shifting the paper backward when it is not in the correct position.
CONSTITUTION: Above a paper feed plate 11 for guiding a sheet of paper 1, are provided paper feed tapes 14, a plurality of vertically movable tape retaining rollers 21 and a detector 31 for detecting whether or not the paper 1 is correctly positioned. Further, paper returning rollers 33 placed almost on a same plane at that of the paper feed plate 11 and driven always toward a backward direction and returning rollers 37 are provided. When the paper 1 is placed in a correct position, the tape retaining roller 21 is pressed to the paper feed tape 14, and simultaneously the retaining roller 37 is lifted to perform paper feed operation. When the paper 1 is not in a correct position, the retaining roller 21 is lifted, and simultaneously the retaining roller 37 is pressed to the paper returning roller 33 to return the paper backward. In this way, paper feed operation can be surely performed.
