搬送されるシートを挟持した状態で前記幅方向にシフト可能なシート搬送ローラと、
前記シート搬送ローラをシートを挟持した状態で幅方向にシフトさせるシフト部と、
を備え、
前記シート搬送ローラを、前記シフト部により、前記ずれ量検出手段が検出した前記幅方向のずれ量に応じて、搬送されるシートのサイズに関わらずシートのシート搬送方向中央部を挟持した状態で幅方向にシフトさせることを特徴とするシート搬送装置。 In a sheet transport apparatus capable of transporting sheets of different sizes in the sheet transport direction,
A deviation amount detection unit for detecting a deviation amount from a conveyance reference position in the width direction orthogonal to the sheet conveyance direction of the conveyed sheet;
A sheet conveying roller capable of shifting in the width direction with the sheet to be conveyed sandwiched therebetween,
A shift unit that shifts the sheet conveying roller in the width direction while sandwiching the sheet; and
With
In the state where the sheet conveyance roller is sandwiched by the shift unit in the sheet conveyance direction central portion of the sheet regardless of the size of the conveyed sheet according to the deviation amount in the width direction detected by the deviation amount detection unit. A sheet conveying apparatus that shifts in a width direction.
前記シート搬送ローラにより搬送されるシートのシート搬送方向先端を検知する先端検知部と、を備え、
前記中央部位置検知部は、前記先端検知部からの先端検知信号と、シートのシート搬送方向の長さと、前記シート搬送ローラのシート搬送速度とに基づいて前記シートのシート搬送方向中央部が前記シート搬送ローラに達したことを検知することを特徴とする請求項１記載のシート搬送装置。 When the sheet is conveyed by the sheet conveying roller, a central position detection unit that detects that the central portion of the conveyed sheet in the sheet conveying direction has reached the sheet conveying roller;
A leading edge detection unit that detects a leading edge of a sheet conveyed in the sheet conveying direction by the sheet conveying roller,
The central position detection unit is configured such that the central portion in the sheet conveyance direction of the sheet is based on the leading edge detection signal from the leading edge detection unit, the length of the sheet in the sheet conveyance direction, and the sheet conveyance speed of the sheet conveyance roller. 2. The sheet conveying apparatus according to claim 1, wherein the sheet conveying roller detects that the sheet has reached a sheet conveying roller.
前記ずれ量検出部は、前記側端検知部からの信号に基づきシートの前記幅方向のずれ量を検出することを特徴とする請求項１又は２記載のシート搬送装置。 Provided with a side edge detector that detects the side edge position in the width direction of the sheet,
The sheet conveying apparatus according to claim 1, wherein the deviation amount detection unit detects a deviation amount of the sheet in the width direction based on a signal from the side edge detection unit.
