Abstract
An image processing apparatus includes a first conveying path, a curved conveying path, a second conveying path, a first image reading section facing the first conveying path, a pair of third conveying rollers having a third nip point P1, a pair of second conveying rollers having a second nip point P4, a second image reading section facing the second conveying path, a pair of first conveying rollers having a first nip point P3 and a pair of discharge rollers having a fourth nip point P2. A distance between P1 and P2 is larger than a distance between P3 and P4. P3 and P4 are positioned in a first area defined by imaginary lines extending upward from P1 and P2 respectively.
Claims13
An image processing apparatus comprising:
- a U-turn conveying path comprising:
- a first conveying path on which a sheet is conveyed;
- a curved conveying path having an arc shape and on which the sheet conveyed from the first conveying path is conveyed;
- and
- a second conveying path on which the sheet conveyed from the curved conveying path is conveyed;
- a first image reading section facing the first conveying path and configured to read an image recorded on a first surface of the sheet conveyed on the first conveying path;
- a second image reading section facing the second conveying path and configured to read an image recorded on a second surface of the sheet conveyed on the second conveying path;
- a pair of first conveying rollers positioned upstream of the first conveying path in a conveying direction and configured to nip and convey the sheet to the first conveying path;
- a pair of second conveying rollers positioned at a boundary between the first conveying path and the curved conveying path and configured to nip and conveyed the sheet to the curved conveying path;
- a pair of third conveying rollers positioned downstream of the curved conveying path in the conveying direction and configured to nip and convey the sheet to the second conveying roller;
- and
- a pair of discharge rollers positioned downstream of the second conveying path in the conveying direction and configured to discharge the sheet from the second conveying path,
- wherein the pair of the first conveying rollers, the pair of the second conveying rollers, the pair of the third conveying rollers and the pair of the discharge rollers are positioned such that a distance between a third nip point that each of the pair of the third conveying rollers contacts each other and a fourth nip point that each of the pair of the discharge rollers contacts each other is larger than a distance between a first nip point that each of the pair of the first conveying rollers contacts each other and a second nip point that each of the pair of the second conveying rollers contacts each other, and
- wherein the first nip point and the second nip point are positioned in a first area defined by an imaginary line extending upward from the third nip point and the fourth nip point respectively.
An image processing apparatus capable of reading an image recorded on a first surface and a second surface of a sheet, the image processing apparatus comprising:
- a conveying path comprising:
- a first conveying path formed in a substantially plate shape;
- a second conveying path disposed below the first conveying path;
- and
- a curved conveying path disposed between the first conveying path and the second conveying path,
- a conveying mechanism configured to convey the sheet along a conveying direction from the first conveying path to the second conveying path through the curved conveying path;
- a first image reading section disposed below the first conveying path and comprising a first image sensor which reads the image recorded on the first surface of the sheet conveyed along the first conveying path at a first image reading position;
- a second image reading section comprising a second image sensor which reads the image recorded on the second surface of the sheet conveyed along the second conveying path from below the second conveying path at a second image reading position;
- a feed tray disposed upstream of the first conveying path in the conveying direction and configured to hold a plurality of sheets in a stacked state;
- a feed unit configured to separate one of the plurality of the sheets held on the feed tray and feed the separated sheet toward the first image reading position;
- a discharge unit disposed below the feed unit and configured to discharge the sheet from the second conveying path;
- and
- a discharge tray disposed below the discharge unit and hold the sheet discharged from the second conveying path by the discharge unit,
- wherein the second conveying path extends obliquely upward from the second image reading position to the discharge unit.
