20090031833 | DRIVING MECHANISM FOR CARRIER, RECORDING APPARATUS, AND READING APPARATUS - A driving mechanism for a carrier can prevent drive transmission units used for reciprocation of the carrier from becoming damaged, dented, or deformed even when an apparatus receives vibration or impact from the outside. The driving mechanism includes first and second pinion components held by a carrier, first and second rack segments fixed to a main apparatus body, and a connector rack segment fixed between the first and second rack segments. When the carrier performs recording, the first pinion component engages with the first rack segment. When the carrier is at a home position, the second pinion component engages with the second rack segment. | 02-05-2009 |
