<p>PURPOSE: To improve stabilizing conveying a sheet material by holding a tilt angle between rotational axial line of conveying rollers and rotational axial line of conveying wheel changeably by a tilt angle variable holding means, and driving it turned in both directions of the sheet material by prescribed timing of action of conveying the sheet material. CONSTITUTION: When carrying a current in a plunger magnet 11 is interrupted, a movable plate 12 is returned to an initial position by energizing force of a return spring 13, to turn a switching pin 10 and a roller holder 4 in the clockwise direction, to minimize a tilt angleθof a diagonal feed roller 3 relating to a conveying roller 2, and by a relation where the tilt angleθ=0, rotational axial lines of the diagonal feed roller 3 and the conveying roller 2 are placed in almost a parallel position. In this way, a sheet material is not diagonally fed and since it is conveyed almost straight with one side surface of the sheet material along a reference plate 1, the sheet material is prevented from riding on the reference plate 1 and from being rotated, after the sheet material is made to collide against the reference plate 1.</p> |
