<p>PURPOSE:To make a device small size and low cost and to carry out accurate paper conveyance by providing a means of conveying a sheet material in cooperation with a feeding means on the lower course side in the sheet material conveying direction of a separating means. CONSTITUTION:Transfer materials 1 on a paper feeding tray 2 are pressed against a paper feed roller 4 by means of a paper feeding pressure spring and, as the paper feed roller 4 is rotated, the ends of the transfer materials 1 are advanced up to a paper guide 2' by friction reaching a separating pad 6. And, plural piled sheets of transfer paper 1 come to stop from the sheet whichever comes in close vicinity to the separating pad 6 earlier and, due to friction, only one sheet of transfer paper 1a passes through between the paper feed roller 4 and the separating pad 6, arrives at a roller 7 which is driven being pressed by the paper feed roller 4, and the sheet of paper 1a is held in between and conveyed. Thereupon, the conveying speed vp of the transfer material 1a is stabilized since the pressing force of the roller 7 against the paper feed roller 4 is sufficiently large with respect to the friction load between the transfer material 1a and the separating pad 6. Hence, the accurate conveyance can be carried out, enabling a device to be low cost and small size and to perform accurate paper conveyance.</p> |
