Abstract
A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system consists of a drive shaft,, a slip clutch,, a clutch gear,, a drive gear,, and a staggered gear,which controls the paper cutter blade,. During printing, clutch,allows the drive shaft,shaft to slip relative to the clutch gear,. When printing stops, clutch,locks clutch gear,which is engaged with the first portion of staggered gear,and causes staggered gear,to rotate until the second portion of staggered gear,engages the drive gear,. Staggered gear,is then driven by the drive gear,. A cutter blade is controlled by staggered gear,, with the blade cutting off the paper as the drive gear,is in reverse rotation. After the paper is cut, drive gear,resumes its forward rotation, rotating staggered gear,and consequently, rotating cutter blade,away from the paper. After the blade has been rotated, staggered gear,continues to turn, until the drive gear disengages with the second portion of the staggered gear. Full torque is applied to both cutting and opening rotations of the cutter blade.
