Optical reader applicable to plurality of uses
First Claim
1. An optical reader for scanning a mark carried by an article using scanning light, detecting light reflected from said mark, and thus reading information represented by said mark, comprising:
- a light source;
a scanning means that is driven by a driving means and scans light emanating from said light source;
a plurality of reflection mirrors for reflecting scanning light scanned by said scanning means and creating a scanning pattern composed of a plurality of scan trajectories;
a read window through which scanning light reflected from said reflection mirrors is emitted; and
a light receiving means for receiving light reflected from said mark;
said optical reader further comprising;
a mode changing means for changing a plurality of operation modes among which one or ones of said plurality of scan trajectories to be validated for reading are different;
said plurality of operation modes including a specific scanning ray mode in which reading said mark using only a specific scan trajectory constituting said scanning pattern is validated and reading said mark using the other scan trajectories is invalidated.

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 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.

45. A stand on which an optical reader, which has a read window through which scanning light is emitted and a grip enabling a user to grasp said optical reader, and which scans a mark borne by an article using scanning light emitted through said read window, detects light reflected from said mark, and thus reads information, is mounted, comprising:
-
a holder section in which said grip is mounted so that said grip can be dismounted freely; and
a base for supporting said holder section so that said holder section can pivot;
said holder section having a slit, through which a cable coupled with said optical reader can pass, on the same side thereof as the side of said optical reader having said read window.
