Abstract
A multihead type image recording apparatus is provided. This recording apparatus includes a single position detector and a position correcting circuit. The position detector detects positional components of an array of laser diodes of each of recording heads in an X-direction parallel to a traveling direction of the recording heads on a recording medium and a Y-direction perpendicular to the X-direction to determine an inclination of the laser diode array. The position correcting circuit adjusts the inclination of the laser diode array of each of the recording heads to a given common angle to compensate for a positional error in the X-direction of the laser diode array, and also controls timing of activation of the laser diodes to compensate for a positional error in the Y-direction of the laser diode array.
