A document reading device includes a second reading carriage 3 provided in a document conveying unit and configured to read a surface of a document different from a surface read by a first reading carriage, a support frame 51 having a support surface 53 that supports the second reading carriage 3, a retaining member 54 that retains the second reading carriage 3 by sandwiching the same between itself and the support frame 51, and an elastic member 55 provided between the second reading carriage 3 and retaining member 54 so as to press the second reading carriage 3 against the support frame 51. One of the support surface 53 of the support frame 51 and a supported surface 42 of the second reading carriage 3 that is supported by the support surface 53 is formed into a curved surface.
