ABSTRACT:
An optical printing head for recording graphic and text information line by line, including a plurality of juxtaposed, actuatable optical components, including picture dot elements, from which light is transmitted in dots by means of objective lenses along the length of a line to be recorded on a photosensitive record carrier, and cross-section converters for conducting light from a light source to the light switching components. To simplify and reduce the cost of the installation of the light switching components and associated light coupling elements (which in known printing heads were mounted and adjusted separately), the light switching components or elements are disposed on a common carrier which is provided with an abutment surface for aligning the light switching elements in the direction of the line, and with a contact surface for the cross section converters used such that, after installation, the cross-section converters will always be perpendicular to the light array of the light switching component. The arrangement permits simple installation of the light switching elements on a carrier in a manner such that each light switching element is automatically disposed exactly opposite the illuminated light conductive fiber forming the associated cross sectional converter.
