Abstract
A printer having a change-over mechanism for selectively transmitting driving power of a line feed motor to a purge mechanism. A power distribution gear driven by the line feed motor is selectively engageable with a purge gear which drives a negative pressure generating unit of the purge mechanism. A first reclinable portion is pivotally positioned at a boundary between a printing region and a capping region, and a second reclinable portion is pivotally positioned in the printing region. The first and second reclinable portions are connected together by a link so as to upstand one of the first and second reclinable portions in response to reclining movement of the other. The first reclinable portion has an idle kicker depressable against the power distribution gear for disengaging the latter from the purge gear. A carriage mounting thereon print heads has a rib which is abuttable against the first and second reclinable portions to obtain their reclining positions. When the rib kicks down the first reclinable portion, the idle kicker moves away from the power distribution gear, so that the latter is brought into engagement with the purge gear. When the rib kicks down the second recl…
