Abstract

An optical read is 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 an array format on a menu sheet in a hand-held state. 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 (or control unit) 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 single scan trajectory consisting the scanning pattern is validated but reading the mark by tracing the multiple scan trajectories is invalidated. For reading any of bar codes set in an array format on a menu sheet, the single scan trajectory constituting the scanning pattern will be drawn on a bar code to be read. Since reading by tracing the multiple scan trajectories is invalid, only the bar code intended to be read is read.

Claims

1. A stand on which an optical reader, which includes 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 stand member on which said optical reader is mounted in such a manner that said grip of said optical reader extends laterally beyond a lateral side of said stand member;

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 stand member having a tongue, which is inserted into said holder section so that said tongue can be removed freely, on a bottom thereof.

2. An optical unit, comprising:

an optical part having first and second stems formed coaxially on opposite edges thereof and a third stem formed in parallel with said second stem on one of the edges thereof; and

a frame on which said optical part is mounted, and which includes a first bearing having a slit shape into which said first stem is fitted, a second bearing into which said second stem is fitted, and a third elongated bearing into which said third stem is fitted and which forms an arc with said second bearing as a center.

3. A stand on which an optical reader, which includes 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 stand member on which said optical reader is mounted in such a manner that said grip of said optical reader extends laterally beyond a lateral side of said stand member;

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,

said stand member having a tongue, which is inserted into said holder second so that said tongue can be removed freely, on a bottom thereof.
