Abstract:
A document feeding device of the present invention includes: a discharge roller pair that includes a first drive roller and a first idler roller; and a transport roller pair that includes a second drive roller and a second idler roller. Either one of the second drive roller and the second idler roller moves between a contact position where said roller is in contact with the other roller and a separation position where said roller is separated from the other roller. The transport roller pair is disposed on the other side of the discharge roller pair from a discharge tray. The transport roller pair transports a document that has passed through the reading position to the discharge roller pair by positioning said roller at the contact position in a case where the first drive roller rotates forward.
