Summary:PROBLEM TO BE SOLVED: To provide a sheet feeder which can save an installation space irrespective of strength of a resilience of a sheet fed out from a loading part.SOLUTION: A sheet feeder includes: feeding means for feeding sheets loaded on a loading part; a separation part which separates the sheets fed by the feeding means one by one; a tip holding part which holds a tip of the sheet fed by the feeding means at a first position on a sheet feeding direction downstream side with respect to the separation part; a guide part for guiding the sheet fed by the feeding means; transfer means which transfers the tip holding part and the guide part between the first position and a second position closer to the feeding means than the first position; releasing means which releases holding of the sheet from the tip holding part which holds the tip of the sheet when the tip holding part is transferred from the first position to the second position; and transportation means which transports the sheet of which holding by the tip holding means is released at the second position and which is fed by the feeding means so that the transportation means transports the sheet in a region on the feeding means side with respect to the first position. 【課題】積載部から送り出されるシートのコシの強さにかかわらず、設置スペースを削減可能なシート給送装置を提供する。【解決手段】積載部に積載されたシートを送り出す給送手段と、給送手段により送り出されたシートを１枚ずつに分離する分離部と、給送手段により送り出されたシートの先端を分離部よりもシート給送方向下流側の第１位置において保持する先端保持部と、給送手段により給送されるシートをガイドするガイド部と、先端保持部とガイド部とを第１位置と第１位置より給送手段に近い第２位置との間を移動させる移動手段と、先端保持部が第１位置から第２位置に移動した際にシート先端を保持している先端保持部からシートの保持を解除する解除手段と、第２位置において先端保持部によるシート保持が解除され、給送手段により送り出されたシートを搬送する搬送手段であって、第１位置よりも給送手段側の領域でシートを搬送する搬送手段とを有する。【選択図】図３２
