Image scanning apparatus

An image scanning apparatus comprising:

• a feeding unit configured to feed at least one document sheet in a feeding direction along a feeding path, the feeding path includes a curved path formed to change the feeding direction with respect to the image scanning apparatus;
• and
• a scanning unit configured to scan an image of the document sheet fed by the feeding unit along the feeding path;
• and
• wherein the feeding unit comprises:
• a main roller configured to be rotated to feed the document sheet along the curved path, a circumference surface of the main roller forming a part of the curved path;
• a separation unit configured to separate the document sheet from other sheets on a sheet-by-sheet basis and convey the separated sheet to the scanning unit;
• and
• a discharge unit configured to discharge the document sheet to a discharge tray, the discharge unit being disposed on an upstream side relative to the discharge tray and on a downstream side relative to the scanning unit in the feeding direction,
• wherein a length of the feeding path from a downstream side end of the scanning unit in the feeding direction to a position of the discharge unit is shorter than a length of the feeding path from a position of the separation unit to the downstream side end of the scanning unit,
• wherein the curved path is disposed only on the downstream side of the scanning unit in the feeding direction,
• wherein the scanning unit comprises:
• a first image sensor configured to scan an image on a first face of the document sheet;
• and
• a second image sensor configured to scan an image on a second face of the document sheet that is opposite to the first face, the second image sensor and the first image sensor being disposed side-by-side in the feeding direction and on opposite sides of the feeding path, and
• wherein one of the first image sensor and the second image sensor is disposed to overlap the main roller when viewed from a direction in which the document sheet is conveyed over the first and second image sensors.
