<p>PURPOSE:To simplify a jam treatment with a single operation knob even in the case where respective conveying rollers are rotation-driven by two driving motors, for example, in a large-size machine. CONSTITUTION:A first rotation transmission system 19 is provided for transmitting rotation of a first driving motor 16 to a conveying roller 10 upstream in the sheet conveying direction. A second rotation transmission system 29 is provided for transmitting rotation of a second driving motor 26 to a conveying roller 20 downstream of the conveying roller 10. A third rotation transmission system 30 to be freely rotation-driven by means of an operation knob 40 is provided between the first and the second transmission systems 19, 29 for joining both. A one way clutch mechanism is provided for preventing rotation transmission from the first and the second rotation transmission systems 19, 29 to the third rotation transmission system 30.</p> |
