Abstract
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 includes 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 includes a control unit to control a change from a multi-scanning mode to a single-scanning mode, wherein a plurality of scan trajectories in different fixed directions intersect at a center of the scan trajectories is validated in the multi-scanning mode, and wherein a scan trajectory in a single direction is validated in the single-scanning mode with invalidation of the plurality of scan trajectories of the multi-scanning mode.
