ABSTRACT:
A light beam scanning and recording device for optically reading a form slide with a raster scan, combining a signal representing the form with a data signal and recording the combined information on a recording sheet also using a raster scan. A portion of a beam scanning the form is split off and directed through an optical encoder device having an alternating transparent and opaque pattern. A detected signal from the encoder is used to detect shifts in the raster scan pattern and to consequentially properly align the data signal with the form information by controlling a clock signal synchronizing the data signal. A common optical system including vertical and horizontal beam deflectors is employed for both reading and recording beams.
