BAR-CODE READING APPARATUS, BAR-CODE READING METHOD, AND LIBRARY APPARATUS

摘要

The present invention relates to bar-code reading from a carried object such as a cartridge and enables the bar-code reading from a gripped carried object. For a bar-code label attached to a carried object such as a cartridge storing a magnetic tape, a bar-code reading unit is provided in a hand unit, which grips the carried object, at a surface opposite to the carried object; the bar-code reading unit includes a light source (light emitting device) that emits light to the bar-code label and a light receiving unit (light receiving device) that receives reflected light from the bar-code label; the bar-code label is detected by scanning with the light; and therefore, the gripping of the carrier object can be performed concurrently with the reading of the bar-code label.
