PROBLEM TO BE SOLVED: To enable formation of appropriate slack in a sheet and thereby prevent the sheet from being folded in a Z shape by providing a curved part that conforms to the shape of a slack guide part.SOLUTION: A paper feeder comprises: a paper feed roller for feeding a sheet from a sheet bundle placed on a paper feed table; a register roller which is disposed on the downstream side of the paper feed roller in a conveying direction and adjusts feed timing of the sheet to a printing part; and a slack guide part having a curved part formed so as to conform to a slack shape of the sheet when a sheet relating to paper feeding is slackened in a paper feed path formed between the paper feed roller and the register roller.SELECTED DRAWING: Figure 2 【課題】弛み案内部の形状に沿うような曲線部を備えることにより、用紙に適切な弛みを形成させることができ、Ｚ折れを防止できる。【解決手段】給紙台に設置された用紙束から用紙を送出する給紙ローラと、前記給紙ローラの搬送方向下流側に配置され、印刷部に対する用紙の送出タイミングを調整するレジストローラと、前記給紙ローラと前記レジストローラとの間に形成される給紙経路において、給紙に係る用紙が弛んだ際、用紙の弛み形状に沿うように形成される曲線部を有する弛み案内部と、を備えることを特徴とする給紙装置。【選択図】 図２
