Abstract
In a label printer, nonspooling and self-strip paths of label stock movement are accommodated by a single mechanism that includes a drive capstan 46 and associated pinch roller 48, a shaft 40, a pair of mechanically intercoupled discs 68 and 52 respectively secured to the shaft and the drive capstan for causing them to rotate in opposite directions, a label stripping pin 44, a drive roller 38 rotatable about the shaft, a clutch 78 locking the drive roller to the shaft whenever the shaft is rotated in a given direction and permitting the drive roller to freely rotate about the shaft whenever the shaft is rotated in an opposite direction, and a thermal print head 28 including a thermal print element 30 yieldably engaging the drive roller. In the nonspooling path, the free end of the label stock is passed between the thermal print head and the drive roller and the drive capstan is rotated in a given direction by a drive motor 54 so that the label stock exits the label printer without label separation. In the self-strip path, a free end of the label stock is further passed around the label stripping pin, over the drive roller, and between the drive capstan and associated pinch roller, and the drive capstan is caused to rotate by the drive motor in a direction opposite to that used for the nonspooling path so that each label is partially separated as the label stock passes over the label stripping pin.
