Abstract: An image reading apparatus includes a first housing, a second housing, an imaging sensor, a reference member provided to be able to move between a first position facing the imaging sensor and a second position, a cam to make the reference member move, and an abutting member provided to make the cam move. The abutting member is located at a projecting position sticking out from the first housing, to make the cam move so that the reference member moves from the first position to the second position when the second housing is closed with respect to the first housing. The abutting member is provided so as to be able to retract when the second housing is opened and closed with respect to the first housing and abuts against the cam in the state located at the projecting position.

Abstract: An overhead scanner 1 includes an imaging unit 22 that images a medium S placed on a mount surface 2 to be read from above and a light source 21 that is arranged to be able to irradiate the medium S with light during imaging by the imaging unit 22. A control device 40 of the overhead scanner 1 performs anti-glare control when detecting that the medium S is glossy. This prevents glare from occurring to the user during operation of the overhead scanner 1.

Abstract: An image reading apparatus includes a reading unit configured to read an image of a medium fed through a first feed path, a switching unit that isolates a third feed path from a junction so as to guide the medium from a second feed path to the first feed path when being disposed at a first position and that guides the medium from the first feed path to the third feed path when being disposed at the second position, and a drive unit that moves the switching unit to the second position when the medium is fed from the first feed path to the third feed path, wherein the drive unit moves the switching unit to the first position after a lapse of predetermined time from a beginning of feeding the medium from the third feed path toward the first feed path.
