PROBLEM TO BE SOLVED: To inhibit skewing in feeding a document or a sheet in a document conveyance device.SOLUTION: A positioning rail 54 determining a fixing position of a guide member 52 and a pair of sliding rails 53 having a guided part 52a provided on the guide member 52 therebetween are obliquely arranged so that an angle &thetas;s formed between the guide member 52 ane the rails at a downstream side of a feeding direction of the sheet 50 is an acute angle. The guided part 52a of the guide member 52 is tilted by only the angle &thetas; with respect to the guide member 52. By being tilted in this way, even under the condition that one pitch p of a positioning uneven part 60 is almost equivalent to that of the conventional device, the fixing position accuracy of the guide member 52 can be finely subdivided into "pitch width p×sin&thetas;", and a gap between an edge of a sheet bundle 50 and the guide member 52 is reduced, and the skewing of the sheet 50 can be inhibited. |
