<p>PURPOSE:To feed a sheet straightforward without the sheet slanting and side-slipping under an external force, by clamping the sheet between one or more pairs of rubber rollers which are rotatable in the sheet conveying direction. CONSTITUTION:A pair of robber rollers 1-a, 1-b are provided upstream of a vibrator 11 in a sheet conveying direction and on the sheet guide 21 side. With this arrangement, even though a force such as an external force f5 or f6 which is orthogonal to the sheet conveying direction is exerted to the sheet, the frictional forces by the pair of rubber rollers 1-a, 1-b can prevent the sheet 13 from slide-slipping.</p> |
