Abstract
A recording apparatus for linewise recording information on a moving photoreceptor by means of a plurality of chips on each of which parallel sub-rows of uniformly spaced radiation sources are formed, wherein a shortcoming of prior art apparatus, namely the impossibility to use chips on which even one radiation source only is defect, is overcome. The apparatus comprises two parallel rows of radiation sources, each row comprising reserve radiation sources that are arranged with corresponding basic radiation sources of the other group in optical parallelism, and connection circuit means for establishing electrical contact with a basic and/or a reserve radiation source (FIG. 5).
