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.

Optical reader applicable to plurality of uses

An install apparatus installs printer firmware to a printer through a network in the background of normal print jobs. The Printer () includes a storage means () to store the firmware consisting of a plurality of blocks, and a processing means () for receiving the blocks to store to storage means (). In case an interruption occurs during the firmware installation and at the time of resuming the installation, the processing means () informs install apparatus () of a guarantee range of the installed blocks being determined from the data stored in storage means (). The install apparatus then restarts transferring the firmware from the succeeding transfer block of the guarantee range.

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.

Stand for pivotably mounting an optical reading device

In a bar-code reading apparatus, an enclosure is provided with various mechanisms, includes a hand-holding portion and a reading portion having a reading window. Projections are provided at two sides of the enclosure, and a cable extends out from one of the projections. The projections engage with supporting-point cut-out portions of supporting portions in a stand, in a stationary condition. The reading window is therefore located lower than the hand-holding portion.
