Confidential
Top-feed rollers
The driven rollers ("Roller, slip hold, top") are supported by lever ("Lever, slip hold, top"). The
solenoid ("Solenoid, slip hold, top") engaged at the tip of the lever causes the lever to open and
close. The operation to absorb the solenoid’s iron core causes the rollers to open. The rollers will
then stay open even after the solenoid power is shut off.

Form stopper
The form stopper positions the slip as it inserted. The stopper is attached to a fulcrum on the
base frame ("Frame, base").When the printer is in standby, the force of the spring ("Spring, form
stopper") forces the tip of the stopper into the paper path, so that the paper cannot enter. When
the printer is ready to start printing, the action of the shutter mechanism cause the lever ("lever,
form stopper O/C") to rotate in the direction A1, pushing the form stopper downward in the
direction A2.
