PROBLEM TO BE SOLVED: To provide a document conveyance device capable of accurately detecting an inclination angle of a document regardless of the size of the document.SOLUTION: In a document conveyance device 11 configured by arranging a pair of left and right side cursors 21, which abuts on the left and right of a document G loaded on a document loading unit 12 for aligning the width direction of the document G, movably leftward and rightward, and arranging a pickup roller 13 and conveyance rollers 14 for conveying the document G and a pair of left and right sensors 24L and 24R for detecting the passage of the document G, the left and right sensors 24L and 24R are respectively attached to positions, within the width of the document G, of the left and right side cursors 21. The sensors 24L and 24R are respectively arranged at positions, through which both left and right ends of the document G pass, of the cursors 21. Further, each of the sensors 24L and 24R is arranged between the pickup roller 13 and the conveyance roller 14 in a document conveyance direction.

PROBLEM TO BE SOLVED: To provide a document angle detection method used in a document conveying device for accurately detecting an angle of a document even when the document is folded.SOLUTION: The document angle detection method used in the document conveying device includes the steps of: arranging two sensors 24L and 24R in a direction orthogonal to a document conveyance direction for detecting passing of a document G; comparing lengths of on-times of the two sensors 24L and 24R; and calculating an angle φ of the document G from a length L calculated from the on-time t of the sensor (24L) having a longer on-time and a document conveyance speed v, and a length Lo of the document. That is, even when the document G is folded, the angle φ of the document G can be calculated from the length L calculated from the on-time t of the sensor (24L) that does not detect the fold and the document conveyance speed v, and the length Lo of the document G with the use of the following formula; φ=cos(L/Lo).
