Printing apparatus having a rotatable member rotatable in incremental steps smaller than the pitch of a detent gear and including means for accurately retaining the rotatable member at a predetermined position when the detent mechanism is inoperable

摘要

There is described a printing apparatus in which line feed is achieved by rotating a platen with a paper advancing motor and the printing is conducted while the platen is stopped by the paper advancing motor. The printer is further provided with a detent mechanism for stopping the platen at the interval of a determined angle, and a solenoid for deactivating the function of the detent mechanism.
