Image-capturing apparatus

An image-capturing apparatus comprising an image-capturing unit having a platen for carrying document originals, and a document conveyance unit disposed above the image-capturing unit, for conveying document originals;

• said document conveyance unit being furnished with a sheet supply tray for carrying document originals, conveyance means for conveying documents from the sheet supply tray while turning them over from front to back, and a sheet discharge tray disposed below the sheet supply tray and above the platen, for storing documents conveyed by the conveyance means;
• and
• said image-capturing unit being furnished with
• a reading unit having a first photoreceptor unit and a second photoreceptor unit arranged in a row along an image-capture sub-scanning direction, a delay circuit for delaying output from said first photoreceptor unit, and an adding circuit for adding first-photoreceptor output delayed by said delay circuit to output from said second photoreceptor unit,
• a scanning unit supported to be shiftable along said platen so as to guide light, reflected from a document original placed on said platen, sequentially into said first photoreceptor unit and said second photoreceptor unit,
• a drive unit for shifting said scanning unit, and
• a control unit for controlling said reading unit and said drive unit;
• wherein:
• said control unit is configured so as to control, during a moving-original data-capture mode in which data capture from a document conveyed by said document conveyance unit is performed, said drive unit and said reading unit to carry out data capture from the conveyed document by halting said scanning unit at a preestablished reading position at one end-ward side of said platen, and so as to control, during a still-original data-capture mode in which data capture from a document placed on said platen is performed, said reading unit and said drive unit to carry out data capture from the document while shifting said scanning unit from the other end-ward side of said platen toward the one end-ward side thereof.
