Image scanning apparatus and control method thereof

An image scanning apparatus comprising:

• a stacking unit on which the document sheet is to be stacked;
• a pair of regulating members configured to regulate a position of the document sheet stacked on the stacking unit, at least one of the regulating members being movable in a width direction perpendicular to a conveyance direction of the document sheet;
• a conveyance unit configured to convey the document sheet stacked on the stacking unit;
• a scanning unit configured to scan an image on the document sheet conveyed by the conveying unit;
• a detecting unit configured to detect a length in the width direction between the regulating members;
• and
• a control unit configured to control a sheet-to-sheet interval when document sheets are to be conveyed by the conveyance unit,
• wherein the control unit specifies, based on the length detected by the detecting unit, a width of the document sheet to be conveyed by the conveyance unit, the control unit sets, in a case where a difference between the length detected by the detecting unit and the specified width of the document sheet is smaller than a threshold, a first sheet-to-sheet interval when document sheets are to be conveyed, and the control unit sets, in a case where the difference between the length detected by the detecting unit and the specified width of the document sheet is larger than the threshold, a second sheet-to-sheet interval which is larger than the first sheet-to-sheet interval as the sheet-to-sheet interval when the document sheets are to be conveyed.

A method of controlling an image scanning apparatus,

• wherein the image scanning apparatus comprises:
• a stacking unit on which a document sheet is to be stacked,
• a pair of regulating members configured to regulate a position of the document sheet stacked on the stacking unit, at least one of the regulating members being movable in a width direction perpendicular to a conveyance direction of the document sheet,
• a conveyance unit configured to convey the document sheet stacked on the stacking unit,
• a scanning unit configured to scan an image on the document sheet conveyed by the conveying unit,
• a first detecting unit configured to detect a length in the width direction between the regulating members, and
• a second detecting unit configured to detect the width of the document sheet conveyed by the conveyance unit,
• wherein the method comprises:
• setting a first sheet-to-sheet interval as the sheet-to-sheet interval when the document sheets are to be conveyed in a case where a difference between the length detected by the first detecting unit and the width of a document sheet detected by the second detecting unit is smaller than a threshold, and
• setting a second sheet-to-sheet interval which is larger than the first sheet-to-sheet interval as the sheet-to-sheet interval when the document sheets are to be conveyed in a case where the difference between the length detected by the first detecting unit and the width of the document sheet detected by the second detecting unit is larger than the threshold.
