摘要： A compact type bar code reader for detecting a bar code symbol provided on a surface of an article. The bar code reader includes a laser beam generation unit for generating the laser beam to be irradiated onto a bar code symbol, and a focus unit for determining a focus of the laser beam, and a scanning pattern forming unit for forming various scanning patterns of the laser beam. The bar code reader also includes a light reflection unit for reflecting the laser beam to and from the bar code symbol, a light collection unit for collecting the laser beam reflected from the bar code symbol, and a light reception unit for receiving the laser beam collected by the light collection unit, and converting it to an electrical signal. The above units are included in a casing so that the laser beam generation unit, the focus unit, the light collection unit, and the light reception unit are arranged at a lower portion of the casing, and the scanning pattern forming unit and light reception unit are arranged at a lower portion of the casing. The light path of the laser beam is formed in such a way that an emitted light path from the laser beam generation unit to the bar code symbol becomes considerably long, and a reflected light path from the bar code symbol to the light reception unit becomes shorter than the emitted light path.

摘要： An optical scanner is disclosed wherein coded bars are scanned by a laser beam to effect reading of a bar code of the coded bars. The optical scanner includes a rotary polygon mirror having a plurality of reflecting portions provided thereon around an axis of rotation thereof for reflecting a laser beam from a light source toward coded bars. Each reflecting portion of the rotary polygon mirror has a plurality of reflecting faces having different inclination angles from each other with respect to the axis of rotation such that an inclination angle of a line of intersection between adjacent reflecting faces of each reflecting portion with respect to the axis of rotation is different from an inclination angle of a line of intersection between adjacent reflecting faces of each of adjacent ones of the reflecting portions on the opposite sides of the reflecting portion with respect to the axis of rotation. Where the rotary polygon mirror of the construction is used, a scanning pattern which is constituted from scanning lines of various directions can be obtained from the rotary polygon mirror. The optical scanner can thus be reduced in overall size and production cost of the device.

摘要： An optical beam scanner, for reading a bar-code, which comprises a housing (10) accommodating therein a beam generator (1) for projecting a laser beam (34) along a fixed axis, a rotary mirror (30, 40) rotatable about its axis (32) and having a plurality of reflection surfaces (30a, 30b) arranged in a polygonal manner on the periphery of a body thereof, which surfaces receive and reflect the laser beam (34) projected from the beam generator (1), and a unit for driving the rotary mirror (30) to rotate at a predetermined speed during the operation. The housing is provided with a window (21) on an upper wall thereof, through which passes the laser beam (35) reflected from the respective reflection surfaces (30a, 30b) of the rotary mirror (30) for scanning a bar-code disposed above the window (21), and each of the reflection surfaces (30a, 30b) of the rotary mirror (30) is formed by a part of a circular cylindrical surface cut out along a height thereof in an elongated rectangular shape and disposed so that a ridgeline (33) is transverse to the axis (32) of the rotary mirror (30). A direction of a normal vector to the reflection surface (30a, 30b) is smoothly varied in one direction along a scanning line (X) on the reflection surface (30a, 30b) traced by sequential points of incidence of the laser beam (34) across the reflection surface (30a, 30b) when the rotary mirror (30) is rotated, whereby the reflected beam (35) traces various linear scanning patterns (A, B), each corresponding to the respective reflection surface (30a, 30b), on a plane of the window (21) above which the bar-code is scanned.
