Abstract
An image recording device equipped with a focal point adjusting mechanism is provided. Displacement of the focal point of a light beam emitted from a recording head in correspondence with the traveling amount of the recording head in the axial direction of a drum is measured in advance after the image recording device has been assembled. Correction data for compensation of the displacement is prepared from the measured amount of displacement and stored in a correction table. At the time of image recording, the focal length is corrected by reading out the correction data from the correction table in response to the traveling amount of the recording head and moving a moving stage in the direction of the optical axis. Therefore, slight displacement of the focal point, which may compromise image quality, can be compensated with a simple device.
