Abstract
【解決手段】
積載トレイ32上のシートと繰出ローラ40を接触、離間させる離接手段と、給紙ローラ41と分離ローラを圧接、離間させる離間手段と、を設け、離接手段にてシートと繰出ローラを離間させ、分離ローラ42をシート給紙方向と異なるシート戻し方向に回転させた後に離間手段にて給紙ローラ41と分離ローラ42を離間させる。
【選択図】 図9
Description
先ず、電磁クラッチCLをOFFし、給紙ローラ41及び繰出ローラ40の駆動系を給紙モータM1から切り離す(ST20)。その後に昇降モータM4を所定量逆転させて停止する(ST21〜ST23)。これによって、積載トレイ32が所定距離下降し、シートの上面が繰出ローラ40の周面から離れる(図8(a)、(b)を参照)。
