PURPOSE:To detect a break in a paper sheet, by providing a pair of flexible members, which are adapted to the paper sheet from its upper surface and bottom surface, and guide plates, corresponding to the flexible members, between two lines of conveying belts in both end parts of the paper sheet and detecting the paper sheet to pass through. CONSTITUTION:Two rows of conveying belts 1, 2 arc provided in both end parts of a conveyed paper sheet 3. A device provides rollers 6, 7, having a pair of flexible members 8, 9 adapted to an upper surface of the paper sheet 3 and its bottom surface, in rotary shafts 4, 5, provided at a right angle with the advancing direction of the paper sheet 3, while guide plates 30, 10 corresponding to the rollers 6, 7. While the device provides photocouplers 14, 15 and 16, 17 in the vertical direction with the paper sheet 3 and photocouplers 12, 13 in the diagonal direction with the paper sheet 3. The conveyed paper sheet 3, if it provides a broken part, is flexed by the flexible members 8, 9, and a break is detected by the photocouplers 12, 13. In this way, the break of the paper sheet 3 is surely detected by a simplified device.
