Abstract
An optical device for non-contact recording image information on a recording material which is in the shape of a cylindrical configuration by a recording head which has a plurality of light waveguides in the form of glass fibers having entrance ends receiving modulated light from individual sources and exit ends facing the recording material and being densely packed in a linear arrangement characterized by the recording head including at least one adjustment plate having a plurality of individual grooves with one groove being provided with each of the waveguides which are secured therein with the exit ends being oriented in a line extending parallel to the cylindrical axis of the material and the recording head including a light source member containing the individual light sources for each of the waveguides arranged at the spacing corresponding to the spacing at the entrance ends of the waveguides so that when the member is secured to the recording head, the individual light sources are aligned with the respective entrance ends of the fibers. Preferably the recording head extends the length of the cylindrical material and is formed by a plurality of individual sub-recording heads …
