Abstract
A sheet feeding device includes an attracting mechanism and a changing mechanism. The attracting mechanism includes a lifting section and a maintaining section. The lifting section attracts a portion of a sheet material that is fed and lifts the portion of the sheet material. The maintaining section attracts an edge of the sheet material that is lifted by the lifting section and maintains an orientation of the edge of the sheet material. The changing mechanism changes at least one of an attraction force that is generated at the lifting section and an attraction force that is generated at the maintaining section.
Claims18
A sheet feeding device comprising:
- an attracting mechanism that includes a lifting section, a maintaining section, and a suction fan, the lifting section configured to attract a portion of a sheet material that is fed and lifting the portion of the sheet material by a first attraction force generated by the suction fan, the maintaining section configured to attract an edge of the sheet material that is lifted by the lifting section by a second attraction force generated by the suction fan and maintaining an orientation of the edge of the sheet material;
- and
- a changing mechanism configured to change at least one of the first attraction force that is generated at the lifting section and the second attraction force that is generated at the maintaining section,
- wherein the changing mechanism is configured to change the first attraction force independently from the second attraction force.
