Abstract
The invention relates to a recording apparatus for effecting recording on a recording material. The recording apparatus comprises a stepping motor, a recording head capable of reciprocating along the recorded material by a drive force of the stepping motor to effect recording on the recording material, an angular position detector for detecting a rotated angular position of a rotor of the stepping motor, a controller for controlling drive of the stepping motor in a closed-loop manner dependent on the detected result of the detector, a controller for operating the stepping motor in a mode of stepwise motor drive, a movement position detector for detecting a movement position of the recording head, and switching circuitry for switching over between the closed-loop control and the stepwise motor drive dependent on the detected value of the movement position detector.
