摘要:
A media feeding apparatus includes: a feed roller, a separation roller, and a pressing portion to press one of the feed roller and the separation roller against the other to form a nip region. A surface of the feed roller has grooves extending in a width direction of the feed roller. The grooves are arranged with a pitch such that at least one groove is always present in the nip region during feeding of the medium. A width of each groove is 0.5 mm or greater and is set such that a contact area ratio is 0.5 or greater, the ratio being a value obtained by {(a surface area of the feed roller in the nip region−an area of the at least one groove of the feed roller in the nip region)}/(the surface area of the feed roller in the nip region). A surface of the separation roller has grooves extending in a circumferential direction of the separation roller.
