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.

摘要： A laser beam generation control system of an optical mark reader device including a laser generating element, a laser generation control unit, a laser scanner unit for scanning a mark, such as a bar code or the like, and a signal processor unit for photoconverting a reflected light to read thereof; wherein the laser beam generation control unit turns ON/OFF the laser generation element by a predetermined duty to carry out a generation of the laser intermittently. Further, when a reflected light from the mark is detected during an intermittent generation of the laser beam, the laser generation element is turned ON to generate a laser beam continuously; and when a reflected light from the mark is not detected for more than a predetermined first time period during a continuous generation of a laser beam, the system is switched from continuous generation to intermittent generation.

摘要： An optical reader capable of reading a bar code in a mounted state when an article carrying the bar code passes and of reading bar codes set in array on a menu sheet in a hand-held state has been disclosed. The optical reader comprises a light source, a scanner that is driven by a drive and scans light emanating from the light source, a plurality of reflection mirrors that reflect scanning light scanned by the scanner and create a scanning pattern composed of a plurality of scan trajectories, a read window through which scanning light reflected from the reflection mirrors is emitted, and a light receiver for receiving light reflected from a mark. The optical reader further comprises a mode changer for changing a plurality of operation modes among which one or ones of the plurality of scan trajectories to be validated for reading are different. The operation modes include a specific scanning ray mode in which reading the mark by tracing only a given scan trajectory constituting the scanning pattern is validated but reading the mark by tracing the other scan trajectories is invalidated. For reading any of bar codes set in array on a menu sheet, the given scan trajectory constituting the scanning pattern will be drawn on a bar code to be read. Since reading by tracing the other scan trajectories is invalid, only the bar code to be read is read.
