ABSTRACT:
To reduce the engineering and operating costs, particularly to save a radiation source and minimize the space requirement of the illuminating device for the automatic reading of markings that are optically recognizable on a carrier, e.g. alphanumeric symbols on shipments such as letters, postcards, check cards, vouchers and the like, the light flux of a radiation source is utilized better by an additional, simple and inexpensive arrangement consisting of two mirrors. These mirrors are disposed around the radiation source and the radiation source generates two radiation beams which are sent on their way to the carrier to be illuminized first through a condenser system and are then redirected by reflectors in such a manner that the angle of incidence alpha of their beam axes to the carrier surface is essentially the same and that, after focusing the radiation beams, both illuminate the same partial area of the carrier.
