Beam scanning copying apparatus

Abstract

This disclosure concerns a beam scanning copying apparatus having transmission function and receiving function of a facsimile apparatus besides reproduction function. The apparatus comprises light generating means for generating a first and second laser beam, modulator means for moduating the second laser beam in accordance with modulating signals, light deflecting means having at least a first and second reflecting face for deflecting the first and second laser beam with predetermined angular ranges, the first face reflecting the light from the first laser beam to produce a first reflected beam and the second face reflecting the light from the modulator means to produce a second reflected beam, a light splitter for splitting the first reflected beam into a first and second split beam, the first split beam being directed onto a document for scanning the document, first photoelectric means for detecting light reflected from the document and for converting it into electrical signals corresponding to an image on the document, storage means responsive to variable clock signals for receiving and storing the electrical signals, timing means coupled to the storage means and responsive to the second split beam for generating the variable clock signals for controlling the timing of the entry of the electrical signals into the storage means, and recording medium means scanned by the second reflected beam for recording information according to the modulating signals.
