Summary:PROBLEM TO BE SOLVED: To provide a feeding device, which can reduce down time caused by lift-up motion at the time of starting operation for feeding a recording material from a cassette after operation for feeding the material from a manual feed tray.SOLUTION: The feeding device has: a first placement part; a second placement part: lifting means that lifts recording materials placed on the first placement part; and detecting means that varies detection results according to the fact that the recording materials lifted by the lifting means reach a feeding position, where the recording materials are lifted by the lifting means until the detection results are varied. The device further has control means that, when the recording material fed from the second placement part passes through the detecting means in a state where the recording material placed on the first placement part is left at the feeding position and therefore the detection results are varied, feeds a first recording material and a second recording material sequentially from the second placement part, and makes the lifting means to lift the recording materials in a period of time during which at least a rear end of the first recording material passes through the detecting means and then a tip of the second recording material reaches the detecting means.SELECTED DRAWING: Figure 6 【課題】 手差しトレイからの給送動作の後にカセットからの給送動作を開始させる場合における、リフトアップ動作によるダウンタイムを低減する。【解決手段】 第一の載置部と、第二の載置部と、第一の載置部に載置された記録材を上昇させる上昇手段と、上昇手段により上昇された記録材が給送位置に到達したことに応じて検知結果が変化する検知手段とを有し、前記検知結果が変化するまで前記上昇手段により記録材が上昇され、前記第一の載置部に載置された記録材が前記給送位置にない状態で、前記第二の載置部から給送された記録材が前記検知手段を通過すると前記検知結果が変化し、前記第二の載置部から第一の記録材と第二の記録材を順番に給送させ、少なくとも前記第一の記録材の後端が前記検知手段を通過してから前記第二の記録材の先端が前記検知手段に到達する迄の時間で、前記上昇手段により記録材を上昇させる制御手段を有することを特徴とする。【選択図】 図6
