Abstract

A image recording apparatus for recording images on a film by a laser beam. The image recording apparatus include a light-emitting element, a monitor element for monitoring the intensity of the light emitted from the light-emitting element, a control means for controlling the intensity of the light emitted for the light-emitting element, and a selection means to select the intensity of the light emitted from the light-emitting element with a selection portion. The monitor element is insulated from the selection portion to keep out of the influence of the external noise.
