Office equipment with image readers and laser printers

摘要

The image analyser incorporates a fixed head (1) with a light-emitting diode (6) and a phototransistor (5), and a mechanical scanner comprising a rotating mirror (16), an angular correction mirror (9) and a return mirror (15). It is combined in a single unit (100) with the printer in which a laser diode (2) and focusing lens (3) are directed at the same rotating mirror. The printer has its own mirrors for correction (8) and return (14) which redirect the laser beam (12) on to the printing drum (7) rotating in contact with the sheet of paper (11). The rotating mirror is positioned at the centre of symmetry of the unit.
