    Abstract: 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).
