ABSTRACT:
An image recording apparatus has an exposing device in which the light from a light source is irradiated to an original text and a photosensitive, pressure-sensitive paper is exposed to the light from the text in correspondence to the image of the text. The image recording apparatus is designed so that the light source and the photosensitive, pressure-sensitive paper have a relative movement by means of a movement device, with the moving speed being varied by means of a moving speed control device. The duration of exposure of the photosensitive, pressure-sensitive paper by the exposing device is varied in response to the moving speed, whereby the level of exposure can be varied. Accordingly, this image recording apparatus, which is simple in structure, accomplishes a variable exposure level for the photosensitive, pressure-sensitive paper without the need of varying the light output of the light source and regardless of the type of the light source.
