ABSTRACT:
In an image information recording apparatus which comprises a laser oscillator, means for deflecting and modulating the laser beam from the laser oscillator by an external signal, a recording medium, optical means for imaging the modulated laser beam on the recording medium and means for causing the laser beam to scan over the recording medium, the light path of the laser beam is divided into a plurality of light path sections and partition plates are provided before and behind each of the light path sections and have holes formed at the portions thereof corresponding to the center of the optical axis. Thus, the optical axis in the apparatus may be adjusted by passing the laser beam through the center of the holes in the partition plates.
