Abstract: An illuminating device for a system for automatically acquiring optically encoded information includes at least one illuminating element, the at least one illuminating element including at least one linear light source extending along a first direction, at least one reflecting optical element associated with the at least one linear light source and suitable for reflecting a light beam emitted by the at least one light source, the optical element having at least one first focus, the linear light source being arranged within an area surrounding the first focus, the illuminating device further includes rotating means suitable for rotating the at least one reflecting optical element with respect to the at least one first focus, with a rotation center arranged within a further area surrounding the at least one first focus.

Abstract: A fixed vision system includes a sensor having a sensitive surface for acquiring an image of an object on a detecting plane, and a light-emitting device for generating a luminous reference figure on the detecting plane including an emission surface, and an objective through which a luminous radiation (from the object to the sensor) and a further luminous radiation (from the light-emitting device to the object) pass. The sensor and the light-emitting device are positioned such that, when the detecting plane is focused by the objective on the sensor, the sensitive surface is on the image plane generated by the objective or on a respective mirror plane with respect to the image plane and the emission surface of the light-emitting device is on the image plane or on a respective mirror plane with respect to the image plane.

Abstract: An optical receiving device (31) for an optical code reader is described, comprising a solid body, of a transparent material, having a light input face (32), a light output face (33) for coupling with a photodetector device (30), said output face (33) being substantially perpendicular to said input face (32), and an oblique face (34) with respect to both said input face (32) and said output face (34), characterized in that the mutual orientation of the faces (32-38, 40-42, 40?, 41?, 42?) of the optical receiving device (31) is such that the light entering from said input face (32) within a desired field of view is concentrated onto said output face (33) by total internal reflection.

Abstract: An automatic optical reading apparatus (1) having a light emitting section (26), a light receiving section (27) and an outside interface section (36). A first unit (2) houses at least one of the emitting section (26) and the receiving section (27) and a second unit (3) houses at least the outside interface section (36). The first unit (2) and the second unit (3) are mutually connectable in at least two different mutual orientations.
