Optical device for non-contact recording

DETAILED DESCRIPTION The present invention is directed to providing an optical device, which is an economical facsimile apparatus and requires a minimum space requirement, which is approximately the space requirement of a normal typewriter.
The object of the present invention is achieved by means of an improvement in an optical device for non-contact recording image information on a recording material, said device having a cylinder for supporting a sheet type recording material in a stretched cylindrical configuration, a recording head being mounted on a guide device for movement parallel to the cylindrical axis with the head being spaced a minimum distance from said stretched recording material, said recording head containing a plurality of light waveguides in the form of glass fibers having exit ends and entrance ends, said exit ends facing the recording material and being arranged linearly and densely packed adjacent to one another, said entrance ends positioned to receive modulated light from individual light sources so that the image information in the form of image points is modulated into the individual light sources to be carried by the individual waveguides to the exit ends for projection onto the recording medium.
The improvement comprises that the recording head includes at least one adjustment plate having a plurality of individual grooves with one groove being provided for each of the waveguides, said waveguides being secured in said grooves with the exit ends being oriented in a line extending perpendicular to the axis of the cylinder, said recording head including a light source member secured thereon, said light source member having the individual light source for each of the waveguides and means enabling individual exciting or activation of each of the light sources in accordance with the image information to be produced, said light sources being arranged in said member with a spacing corresponding to the spacing of the entrance ends of the fibers so that when the member is secured on the recording head, the individual light sources are aligned with the respective entrance ends of the fibers
