- 搬送路に沿ってシート体を搬送し、搬送される前記シート体の搬送方向に対する傾きを補正して前記シート体の搬送を行うシート体搬送装置において、
前記シート体をニップして前記シート体に搬送力を付与し前記搬送路に沿って前記シート体を搬送する複数の搬送ローラ対と、
前記複数の搬送ローラ対の中の1つの搬送ローラ対を前記搬送路と垂直な平面内で前記搬送路の幅方向と平行な基準位置から傾け、前記搬送路の幅方向両端で搬送路長に差を生じさせて前記シート体の傾きを補正する傾き補正手段と、
前記傾き補正手段の上流側に配置された搬送ローラ対を、前記シート体をニップするニップ状態からニップしないニップ解除状態に切り替えて、前記上流側の搬送ローラ対による前記シート体に作用する搬送力を除去又は減少させる第1搬送力切替手段と、
前記傾き補正手段に設けられ、前記1つの搬送ローラ対にニップされた前記シート体をニップ状態からニップ解除状態に切り替えて、前記1つの搬送ローラ対による前記シート体に作用する搬送力を除去又は減少させる第2搬送力切替手段と、
前記傾き補正手段の下流側に配置された搬送ローラ対に前記シート体の前端が到達して前記シート体に搬送力が作用した後、前記シート体の搬送方向長さに基づいて前記第1搬送力切替手段及び前記第2搬送力切替手段を制御して、前記下流側の搬送ローラ対よりも上流側に配置された複数の搬送ローラ対の少なくとも1つをニップ解除状態に切り替える制御手段と、
を備えたことを特徴とするシート体搬送装置。 - 前記シート体は、使用頻度が高い第1シート体と、この第1シート体よりも搬送方向長さが長い第2シート体との複数種類のものが用いられ、前記第1シート体の搬送時には、前記第1搬送力切替手段及び前記第2搬送力切替手段によって前記搬送ローラ対をニップ力解除状態としないことを特徴とする請求項1記載のシート体搬送装置。
- 前記第1シート体の搬送方向長さに近く且つこの搬送方向長さを超える長さを基準長さとし、前記第2シート体の前端が前記下流側の搬送ローラ対を通過後、この搬送ローラ対よりも上流に配置され、前記第2シート体をニップする搬送ローラ対のうち、前記第2シート体の前端との距離が前記基準長さと等しくなった搬送ローラ対から順次ニップ力解除状態とすることを特徴とする請求項2記載のシート体搬送装置。
- 前記第1搬送力切替手段及び前記第2搬送力切替手段は、ニップ力解除状態とされた搬送ローラ対のうち、前記シート体の後端が通過した搬送ローラ対から順次前記ニップ状態に復帰させることを特徴とする請求項1〜3いずれかに記載のシート体搬送装置。
