<p>PURPOSE:To prevent jamming by performing paper feed only when paper feed rolls are rotating to contact the forward feed rolls against the paper while separating the forward feed rolls from the paper upon stoppage of paper feed rolls. CONSTITUTION:Upon stoppage of rotary shaft 6, the supporting member 3 is lifted because the tensile force F1 of spring 5 is higher than the frictional force F3 thus to feed out the paper P through forward feed rolls 2. Upon rotation of said shaft 6, said rolls 2 will contact against the paper P because the rotary force F2 to be applied onto the supporting member 3 is higher than the tensile force F1 of the spring 5 to rotate synchronously with the paper feed roll 1 thereby the paper P will pass over the paper feed roll 1 and contact against a resist roller 10. Then the rotary shaft 6 will stop to stop the paper feed roll 1 thus to separate the forward feed roll 2 from the paper P through tensile force F1 of spring 5 and to stop carrying of paper P.</p> |
