Abstract
In an ink jet type print recording apparatus, a predetermined number of pulses are first produced in a positive direction when gear disengagement is carried out to drive an line feed motor in a forward direction at an angular amplitude within a half of a gear tooth width. Subsequently, pulses whose number is twice as large as the predetermined number are produced in the opposite direction to drive the line feed motor in the reverse direction. Subsequently, a predetermined number of pulses are produced in the positive direction again to drive the line feed motor in the forward direction. With this operation, an idle gear is smoothly disengaged from a link target gear. The line feed motor is reciprocatively driven in the same manner as described above when the idle gear is linked to a new link target gear.
