<p>A picture recording device for medical use which has a very short optical path in an optical system and has a reduced number of mechanically operating parts. The picture recording device electronically scans a LED array assembly (14) having a plurality of LED's that are one-dimensionally arranged by means of a LED array controller (28), and feeds a photosensitive recording medium (15) in a direcion at right angles with the direction in which the LED's are arranged using a motor (17) controlled by a film feed controller (29). The LED array controller and the film feed controller operate according to instructions from a scan controller (27) which is governed by a CPU. The light emitting amounts of the individual LED's in the LED array assembly are controlled by signals that are obtained by formatting the image data stored in an image data storage memory (22) by an image formatter (25) via an input interface (21), the signals being converted into analog signals through a D/A converter (26) or a pulse width modulation circuit (30), and being supplied to the LED array controller.</p> |
