Abstract:
A paper feed roller (21) is rotated in a paper feed direction in response to a printer start instruction after a paper feed cassette (40) is loaded in the printer to feed recording paper into the printer. Since the paper feed cassette is inserted in the printer at the paper feed opening side thereof and has no other opening, excellent light-shielding and moisture-proofing properties are ensured for recording paper. The paper feed roller is reversely rotated immediately after power-on, immediately after loading of the paper feed cassette and/or immediately before paper feed start to return the recording paper to a specified paper feed start position, thereby preventing duplicated feeding and jamming of the recording paper. On completion of printing, the paper feed roller is rotated reversely to return half-fed recording paper to the paper feed start position, so that sheets of recording paper are kept in a close contact condition, light-shielded and moisture-proofed.
Abstract:
A feed mechanism is disclosed for feeding sheets from a sheet store, comprising:, a reversible feed assembly arranged to feed sheets out of and, upon reversal, into the sheet store; and a separator assembly arranged to receive sheets from the reversible feed assembly and adapted to pass sheets singly into a transport path. The separator assembly comprises: a first rotatable separator member arranged to be driven, in use, towards the transport path and being provided with first retardation means for at least decelerating rotation in the opposite sense; a second rotatable separator member (321) opposing the first to define a nip therebetween, the second rotatable separator (321) member being freely rotatable towards the reversible feed assembly, and having second retardation means for at least decelerating rotation in the opposite sense. Reversal of a sheet out of the nip by the reversible feed assembly causes rotation of the second rotatable member. A sheet feeding method is also disclosed.
Abstract:
Un module de stockage (1) comprend une zone de stockage (3) pour stocker par accumulation des articles plats (2) en pile sur chant, un convoyeur principal (9) qui s'étend transversalement à la zone de stockage, une fonction d'empilage pour transférer un article du convoyeur principal vers la zone de stockage et l'empiler à l'arrière de la pile d'articles dans la zone de stockage, et une fonction de dépilage pour extraire un article de la pile d'articles et le transférer vers le convoyeur principal. La fonction de dépilage comprend une plaque de dépilage (7) à courroie perforée et à aspiration commandée disposée entre le convoyeur principal et la zone de stockage, cette plaque de dépilage présentant un premier segment parallèle à la pile d'articles et un second segment adjacent au premier segment et qui s'étend de façon oblique par rapport au premier segment, ladite aspiration commandée étant disposée dans le second segment oblique de la plaque de dépilage.
Abstract:
The present invention relates to a sheet feeding device including a movable wall (6) which is tiltable to regulate the leading edges of sheets stacked. When a sheet feed roller (5) is operated to perform a sheet feeding operation, a loop (12) is formed in the uppermost sheet. After formation of the loop, the movable wall is moved to a regulation release position to remove the loop formed in the uppermost sheet. After removal of the loop (2), the movable wall is returned to a regulation position to raise the leading end of the uppermost sheet so as to separate the uppermost sheet from the second and subsequent sheets.
Abstract:
A media retraction system includes a loadstop shaft rotatable about an axis thereof, and a loadstop paddle rotatably coupled with and slidably mounted on the loadstop shaft such that the loadstop paddle is slidable about the axis of the loadstop shaft.
Abstract:
A media separator (450) comprising an elastomeric element (460) mounted in a frame (452) and including a plurality of fingers (465) wherein, when unbent, the ends of the fingers extend to interfere with a movement of a media sheet. When a finger (465) is bent by a sheet of media it is moved to a recess position such that it does not extend to interfere with the media sheet.
