IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To facilitate miniaturization of a device by extremely simplifying the structure of a reciprocating mechanism of a paper transport roller and to reduce operation noise in reciprocating the paper transport roller. SOLUTION: This image formation device has the paper transport roller connected to a driving source changeable to forward/backward rotation and supported so as to be axially reciprocated. The paper transport roller is connected to the driving source 20 through helical gear mechanisms 9 and 10. COPYRIGHT: (C)2006,JPO&NCIPI
