Drum type image scanning and recording apparatus

摘要: A drum type image scanning and recording apparatus, with a around whose cylindrical external surface film is fixedly wrapped drum-driving apparatus mechanically coupled to the for rotating drum, has string tensionally stretched nearby along surface: of in parallel axis by stretching device. swing detecting device detects produced when part are contact each other, as separates away from surface. The rotation stopped response an abnormality detection signal device, thus precluding significant physical separation drum.
