PROBLEM TO BE SOLVED: To eliminate the need for accuracy at arrangement positions of respective document detection parts which detect an end of a document, wile making a correct document conveyance control available according to a document inclination by accurately detecting the document inclination.SOLUTION: A document conveyance mechanism 6 comprises: a first document detection sensor 661; a second document detection sensor 662 arranged at a different position than the first document detection sensor 661 in both a document conveyance direction and a perpendicular direction thereto; a pulse number detection part 101 which detects a pulse signal number for a drive control of a driving device M; a determination part 102 which determines whether or not a pulse number detected by the pulse number detection part 101 is over a predetermined value in the period from when the end of the document is detected by either of the sensors 661, 662, to when the end of the document is detected by the other sensor; and a control part 100 which stops the driving device M when the detected pulse number is determined to be over the predetermined value. |
