- シートに追従して回転する従動ローラと、
前記従動ローラの回転が伝達されることにより前記シートの移動量を検出可能に設けられた移動量検出手段と、
前記従動ローラが逆回転した際に前記移動量検出手段が前記シートの移動量を検出しなくなる範囲である不感帯範囲を設ける不感帯機構と、
を備え、
前記不感帯機構は、前記従動ローラの回転を前記移動量検出手段に伝達すると共にバックラッシュを有する複数の歯車により構成されており、
前記不感帯範囲は、前記歯車のバックラッシュによって前記従動ローラの逆回転が前記移動量検出手段に伝達されなくなることにより設けられていることを特徴とするシート給送装置。 - さらに、前記移動量検出手段に対して前記移動量検出手段の回転軸方向の付勢力を与える付勢手段が備えられていることを特徴とする請求項1に記載のシート給送装置。
