Classification: CPC H | IPC H

Claim 6:
7. The image reading apparatus according to claim 2, wherein
the control section
performs control in the high output mode by using the high power-feeding USB device as a power supply source in a coupling state where the high power-feeding USB device is coupled without the AC adapter coupled, and
continues the control in the high output mode by continuously using the high power-feeding USB device as the power supply source when a coupling state is changed from the coupling state where the high power-feeding USB device is coupled without the AC adapter coupled, to a coupling state where the AC adapter and the high power-feeding USB device are coupled during image reading at the second reading speed in the high output mode, and continues the control in the high output mode by using the AC adapter as the power supply source, after the image reading at the second reading speed is ended.
