Hellfax - Transceiver HF 1048 |
|||||||||||||||||||||||||||||||||||
Facsimile devices transmit documents with only black and white pixels, i.e. Texts and drawings.
The device presented here is a further development of the HF 146 by Siemens. |
|||||||||||||||||||||||||||||||||||
When operating as a transmitter devive, the document to be transmitted is mounted to the drum.
The scanning unit attached to the optics trolley is guided past the rotating drum with the help
of the closed nut segment and the spindle. The scanning light is directed on the drum from above,
and the reflected light is converted into electrical signals by means of a photo cell. The signals representing the black and white pixels are then sent over the transmission line. |

In the receiving device, the incoming electrical signals are applied to a burning
needle and so writes or burns the black pixels on an electrosensory sheet
that is mounted onto the drum.
