Summary:To provide a feeding unit causing no positional change of a retard roller for every exchange of a holder, in a constitution of holding the retard roller with a holder.SOLUTION: A feeding unit 50 has a retard roller 52, a holder part 94, protrusion parts 132, a housing part 70, a pressing part 152, a first restriction part 172, and a second restriction part 176. The holder part 94 holds rotatably the retard roller 52. The protrusion part 132 serves as a supporting point of oscillation of the holder part 94. The housing part 70 houses the holder part 94. The pressing part 152 presses the holder part 94. The first restriction part 172 restricts movement of the holder part 94 in the retreating direction. The second restriction part 176 restricts movement of the holder 94 in a direction opposite to a retreating direction. The pressing part 152 is positioned displaced in a Y direction in relation to a virtual line G passing through a middle point of the protrusion part 132 and a middle point of the first restriction part 172. The holder part 94 comes into contact with the first restriction part 172 and the second restriction part 176.SELECTED DRAWING: Figure 18 【課題】リタードローラーをホルダーで保持する構成において、ホルダーを交換するたびにリタードローラーの位置が変わる虞がある。【解決手段】給送ユニット50は、リタードローラー52と、ホルダー部94と、突出部132と、収容部70と、押圧部152と、第1規制部172と、第2規制部176とを備える。ホルダー部94は、リタードローラー52を回転可能に保持する。突出部132は、ホルダー部94の揺動の支点となる。収容部70は、ホルダー部94を収容する。押圧部152はホルダー部94を押圧する。第1規制部172は、ホルダー部94の退避方向の移動を規制する。第2規制部176は、ホルダー部94の退避方向とは反対方向の移動を規制する。押圧部152は、突出部132の中点と第1規制部172の中点とを通る仮想線Gに対してY方向にずれて配置される。ホルダー部94は、第1規制部172及び第2規制部176と接触する。【選択図】図18
