Summary: | PROBLEM TO BE SOLVED: To provide a sheet feeder capable of preventing elevating means from being damaged, and an image forming device.SOLUTION: In the sheet feeder, a pickup holder 106 rotatably holds a pickup roller 101 that comes in contact with a sheet S supported by a multi-paper feeding tray 105 from above and feeds the sheet S, and the elevating means moves the pickup holder 106 up and down so that the pickup roller 101 is moved to a position in contact with the sheet S or a waiting position above the sheet S. Between the pickup holder 106 and a link member 107 is provided a compression spring 110. When external force is applied from above onto the pickup holder 106 at the waiting position, the pickup holder 106 is lowered with the compression spring 110 being elastically deformed.
【課題】昇降手段の破損を防ぐことのできるシート給送装置及び画像形成装置を提供する。【解決手段】マルチ給紙トレイ105に支持されたシートSに上方から当接してシートSを送り出すピックアップローラ101を回転可能に保持するピックアップホルダ106を、昇降手段により昇降させ、ピックアップローラ101をシートSと当接する位置及びシートSの上方の待機位置に移動させる。そして、ピックアップホルダ106及びリンク部材107の間に圧縮ばね110を設け、ピックアップホルダ106が待機位置に移動している状態でピックアップホルダ106に上方から外力が加わった際、圧縮ばね110を弾性変形しながらピックアップホルダ106を下降させる。【選択図】図2 |
