c Paper Feed Section
chap.2
The drive power to the paper feed roller is transmitted via the pinion gear, stopper gear and spring clutch.
When the solenoid (SL1) comes on, making the stopper lever move clear of the stopper gear, the paper feed
cam is freed and rotates, causing the paper feed segment to execute a reciprocating motion. This motion is
transmitted to the pinion gear, which, via the action of the spring clutch shown in the mechanism illustration
below, makes the paper feed shaft (and hence the paper feed roller) rotate in a single direction (the paper feed
direction).
When SL1 turns off, the stopper lever is reapplied to the stopper gear, and the pinion gear’s motion ceases to
be transmitted to the paper feed roller shaft.
