The Electrophotography has made possible a photographic-type direct recorder.
The recording paper is daylight loaded, and the completely processed, permanent record is ready for use on leaving the recorder. There is no deterioration of the recording from brightsunlight.
Copies can be made directly with a conventional diazocopying machine.
A schematic diagram of general purpose electrograph is shown in Fig. 1
The device is constructed with a super-high pressure mercury lamp and a mirror-type galvanometer off high-sensitivity so that it gives the writing rate of about 45 meters per second. (700 c/s, ±10mm)
A trial produced a directing recorder with an electro-photographic paper which permits immediate trace up to high frequency to which an ink-writing or a heat-styles recorder has never reached and in addition, it can record the exposure up to high radioactive intensties.
