    Abstract: This invention relates to an ink jet recording apparatus with a support member for supporting an ink jet recording head for effecting recording by ink discharge onto a recording material, comprising: recording material transport means for transporting the recording material from a feeding position through a recording position to a discharge position; and recovery means for maintaining and restoring the ink discharge state of said ink jet recording head. Wherein the driving source for driving said recording material transport means or said support member is also used for driving said recovery means, and, when the power supply to the apparatus is turned on, the initial operations of at least the recording material transport means and said recovery means are conducted utilizing single sensor.

    Abstract: In a sheet transport unit for recording systems which uses a pulse motor (8) to feed a recording sheet (2) quantitatively and intermittently, multiple different current apply intervals are specified within the stop period during intermittent sheet feed, so that a maximum amount of current will be applied to the first interval immediately after the drive stops. Thereby, the pulse motor (8) is never be damaged due to its temperature rise despite a load variation and the load variation can be absorbed enough to ensure high positioning accuracy.
