Abstract
PURPOSE: To accurately detect a sheet jam by detecting the sheet jam by means of the rotation of a roller for carrying the sheet.
CONSTITUTION: Rollers 4, 5 are supported via bearings 2, 3 at a side plate 1 with the roller 4 urged onto the roller 5 via a pressing plate 6 and a pressing spring 7. A driven gear 9 is engaged in mesh with a drive gear 8. The gear 9 and frictional plate 11 are urged by a spring 12 to generate frictional force between the gear 9 and the frictional plate 10, 11. The drive force is transmitted by this frictional force to the roller 5 to thereby carry a sheet 13 interposed between the rollers 4 and 5. A disk 14 having a number of holes is so mounted at the shaft end of the roller 5 as to integrally rotate with the roller 5. Further, light emitting and receiving elements 15 are provided at both sides of the disk 14. Thus, the sheet 14, if jammed, does not rotate the roller 5 and the disk 14 itself to eliminate the predetermined periodical signals from the elements 15.
