    摘要: According to an embodiment, an ADF includes: a sheet-feed cover unit; a switch unit to be switched on or off depending on whether the sheet-feed cover unit is open or closed and including a first terminal, to which a first voltage, by which a driving motor is driven, is input, and a second terminal connected to the driving motor; and an open/close-detection circuit unit that includes a first switch circuit and a second switch circuit. The first switch circuit is switched on or off based on a threshold voltage that is larger than a second voltage to be generated in the driving motor by a jammed-document removing motion and smaller than the first voltage. The open/close-detection circuit unit detects that the sheet-feed cover unit is closed when the second switch circuit is energized, but detects that the sheet-feed cover unit is open when the second switch circuit is de-energized.
