PROBLEM TO BE SOLVED: To prevent generation of an abnormal noise caused by the vibration of a sheet due to the slip phenomenon in continuing the drive of a feed roller in a condition where the sheet is stopped. SOLUTION: This sheet feeder exclusive for manual feed is provided with a paper feed base 32 to guide a sheet to be inserted from a paper feed port 30 to a feed roller 31, and the guide sheet P is fed to a resist roller 20 to stop and arrange a tip of the sheet by the paper feed roller 31. The sheet P is fed by the feed roller 31, and guided along a guide 34 to guide the sheet to the resist roller 20. A second guide 35 is provided along the guide surface of the guide 34 in order to bridge a sheet carrying path between the guide and the feed roller 31. When the feed roller 31 is continuously operated in a condition where the sheet P is stopped by the resist roller 20, the sheet P is vibrated through the slip phenomenon with the sheet P, but the vibration is suppressed by increasing the contact area with the second guide, and thus, the vibration noise is reduced to prevent generation of an abnormal noise.
