ABSTRACT:
To provide for a single-sheet feeding to an office-type writing apparatus, such as a typewriter, word processor, printer or the like, in form of a separable attachment unit, a unitary assembly is provided including two parallel rockers (2, 12) having lateral sheet guide walls (12) which are located on a common shaft (9) connecting side walls of the attachment apparatus. An abutment element (18) movable with the rockers is located adjacent the ends of the leading or feeding edge of sheets of a stack (6) placed on the rockers, the rockers each also including a sheet separating element (28) in form of a small triangle, pivotably secured to a holder plate (26), the base of the small triangle being spaced from the abutment element by a small distance (a) so that, upon engagement of a topmost sheet with a feed roller (15), driven, for example, intermittently to feed a sheet to the slewing mechanism of the writing apparatus by being coupled to the platen (3) thereof, the topmost sheet will be bowed slightly and thus readily separated from the sheet therebeneath.
