When scanning a document, an image scanning device conveys the document toward an image scanning position in a power supply stop state in which power supply to an electronic component is stopped, sets a power supply state in which power is supplied to the electronic component before scanning the document at the image scanning position, scans the document at the image scanning position in the power supply state, and sets the power supply stop state after scanning the document at the image scanning position.
Claims9
An image scanning device comprising:
- an image scanning sensor including a substrate provided with a plurality of scanning elements and electronic components provided, the image scanning device conveying a document to be scanned by the image scanning sensor toward an image scanning position, and scanning the document conveyed to the image scanning position by the image scanning sensor;
- and
- a power supply controller that controls supply of power to the electronic component in the image scanning sensor, wherein
- when scanning the document, the image scanning device
- conveys the document toward the image scanning position in a power supply stop state in which power supply to the electronic component is stopped by the power supply controller,
- sets a power supply state in which power is supplied to the electronic component by the power supply controller before scanning the document at the image scanning position,
- scans the document at the image scanning position in the power supply state, and
- sets the power supply stop state after scanning the document at the image scanning position.
