Abstract
PURPOSE:To make it possible to improve stop characteristics of a driven body by suppressing unneeded vibration greatly by combining a mechanical stopping mechanism with an electronic controller. CONSTITUTION:In addition ratchet 7, locking mechanism 10 is added which drives locking piece 9 for stopping ratchet 7 by catching tooth 8 of ratchet 7. While motor control circuit 14 turns type wheel 2 in a direction where a locking method or ratchet 7 is locked by mechanism 10, fixed type bar 1 reaches a print position and the moment unneeded vibration is caused, motor 3 is reversed to stop mechanically wheel 2 from turning by the locking method. In this way, while merits of conventional electronic or mechanical unit are utilized, their demerits, i.e. the need for skill of a high order and accurate control mechanism are completely eliminated.
