摘要： Examples disclosed herein relate to a device including a separator. Examples include a first separator having a surface to contact a medium and is coupled to a first spring. In examples, the first separator has a first centerline in a direction perpendicular to a medium travel direction. Examples include a second separator having a surface to contact a medium and is coupled to a second spring. In examples, the second separator has a second centerline disposed substantially parallel to the first centerline. Examples include a roller to contact the medium to move the medium along the medium travel direction. In examples, the first spring and second spring bias the first separator and second separator towards the roller, respectively. In examples, a force applied by the first separator to the medium is independent of a force applied to the medium by the second separator.

摘要： A sheet feed device (3) includes: a sheet accommodation unit (31); a separation roller (34) that applies conveyance force to sheets (P); and a separation resistance body (35) including a friction portion facing the separation roller (34) for separating the sheets one at a time. The sheet accommodation unit (31) includes a guide portion (110) provided at an upstream of the separation roller (34) in a sheet feed direction for guiding the sheet. The separation resistance body (35) includes an extension portion (513), which is pressed toward the separation roller (34) while being supported to be contacted/separated to/from the separation roller (34), and which is extended upstream in the sheet feed direction from an upstream end portion of the separation resistance body (35). The guide portion (110) and the extension portion (513) are arranged in a line in a width direction. An upstream end portion (514) of the extension portion (513) is retreated with regard to a guide surface of the guide portion when feeding the sheets.
