PURPOSE:To feed a sheet without double feeding by roughing part of one side surface of the sheet to a specific roughness. CONSTITUTION:A sheet 1b is formed, for example, in a film state of polyester resin, and provided with a roughed surface 7 in which a rear surface of an outer peripheral edge is roughed in a specific width. Roughness of the roughed surface is set, for example, to sufficient mean roughness of Rz 40mum (Rz>=-20mum). Since the sheet has such a structure, when the sheets 1b are integrated to a cassette 2 and fed by rotation of a feed roller 3, contact area of the superposed sheets 2b is reduced, and hence close contact is alleviated. Thus, the sheets 1b can be fed one by one without double feeding. |
