    摘要： Light-beam scanning apparatus mainly used for a bar-code reader in a point-of-sale system to identify sold articles. The apparatus comprises at light-beam emitting device (3), a hologram disk (1) having a plurality of hologram segments with different diffraction characteristics mounted along its circumference and being rotated at a predetermined speed, and deflecting means (5, 16, 19) for directing the emitted light beam from the light-beam emitting device to one side of the hologram disk at a first direction. The scanning apparatus further comprises a first mirror group (20) including a plurality of mirrors placed at a second direction corresponding to the other side of the hologram disk, each of which mirrors is arranged to receive a diffracted light beam from a corresponding hologram segment, and a second mirror group (30) including a plurality of mirrors, each of which mirrors is placed to receive a light beam reflected by a corresponding mirror of the first mirror group and to reflect the incident light beam to a predetermined space (50). positioned in the first direction where an article (14) having a bar-code label (15) is moved. In the apparatus, a light path from the other side of the hologram disk to the predetermined space has a predetermined length to form a predetermined scanning light pattern in the space.

    摘要： A multi-head optical scanning device used for a bar code reader having a reduced thickness and realizing more complete 360° bar code reading. The scanning device includes a bottom part (1), a side part (4) which is nearly vertical to the bottom part, a light source (5), a polygon mirror (6) and a light detector (8) contained inside the body of the side part. Light beams are emitted from the light source (5) so that they are nearly vertical to the surface of the bottom part (1), and the polygon mirror (6) has a rotation axis at a position which is nearly parallel to the surface of the bottom part. The optical scanning device eliminates the need for a mechanism which performs scanning inside the bottom part and the degree of freedom with which each of the pattern mirrors is disposed is increased, and provides a scanning pattern whose reading capacity can be upgraded by using a scanning pattern which is emitted from the bottom part (1).
