Ricoh A156 - Drive Mechanism

2.2 DRIVE MECHANISM
The drive from the main motor is transmitted to the drum drive pulley via the
timing belt [A]. The pick-off pawls [B] are always in contact with the drum
surface under a light spring pressure. They move from side to side during
the copy cycle. This movement is made with a worm gear [C] and an
eccentric cam gear [D].
