Abstract
A drive transmission mechanism in a recording apparatus in which after a drive force transmission gear is meshed with a negative pressure gear, the meshing state of both the gears can be held during maintenance operation irrespective of movement and position of a carriage. When a rib of the carriage kicks a kick portion, a drive force distributing gear (a drive force transmission gear) is released from a pressing force of an idle kicker and slidably moved by being biased by a compression spring. In a notch (cutaway) portion, meshing teeth are meshed with a purge gear (negative pressure gear). By this meshing, when the purge gear starts rotate, even if an idle kicker presses the meshing teeth during rotation, a collar portion suppresses the sliding movement of the meshing teeth, unless the notch portion rotates to a position corresponding to the meshing teeth (a home position), so that the purge gear is not disengaged from the meshing teeth.
