Abstract: An article management system includes an article location specifying means which outputs a location information of an article by relating an object location information with an article identification information. Radio tag information including the article identification information is output from a radio tag reading means which executes through a leaky transmission path a communication with a radio tag affixed on the article on a table section and the object location information is output from an object detection means when detecting the object approaching the table section.

Abstract: The article management system comprises an item placement position memory unit that stores item identification information and item position information, a wireless tag reading unit that reads a wireless tag attached to the item and outputs wireless tag readout information, an item identification information acquiring unit that acquires the item identification information of the item based on the wireless tag readout information output by the wireless tag reading unit, an object detecting unit that detects an object approaching the placement unit and outputs object position information, an item position identifying unit that associates the item identification information and the object position information and outputs the associated information as item position identification information, and an item position determining unit that compares the item position identification information with the item position information stored in the memory unit and outputs a comparison result.

Abstract: An article management system includes: a radio tag reading means, which carries out a communication with a radio tag affixed on an article displayed on a table section, for outputting a radio tag information including an article identification information; an object detection means for detecting an object approaching the table section for outputting an object location information; an article identification information acquiring means for acquiring an article identification information of the article based on the radio tag information outputted from the radio tag reading means; and an article location specifying means, which relates the object location information with the article identification information, for outputting it as location information of the article. The location information is displayed on a display.

Abstract: An article management system is provided with an article placement position storage section which stores article identification information of a plurality of articles and article position information showing a section on which the plurality of articles is placed in association with each other, an object detection section which measures a position of an object positioned inside the section or outside the section to output object position information, and an article specification section which compares object position information detected by the object position detection section and the article position information with each other and, when the object position information is included in section where the article is placed, shown by the article position information, specifies the article identification information stored in association with the article position information.

Abstract: A bar code scanning apparatus having a laser beam source 1, a scanner 7 for scanning a laser beam 2 emitted from the laser beam source 1 in an scan angle range of -.theta..sub.1 to +(.theta..sub.1 +.theta..sub.2) relative to the laser beam, a window 5 substantially perpendicular to a counter surface and which transmits therethrough scan beams scanned by the scanner 7 to the exterior of the reader, a plurality of first fixed mirrors 8A, 8B and 8C for dividing scan beams, which are generated within the scan angle range of -.theta..sub.1 to +.theta..sub.1, into a plurality of scanning lines generally symmetric with respect to the laser beam and emitting the scanning lines from the window 5, and a plurality of second fixed mirrors 26A, 26B1 and 26B2 for dividing scan beams which are generated within the scan angle range of +.theta..sub.1 to +.theta..sub.2 and emitting the resulting scanning lines from the window 5 toward a checkout counter.

Abstract: In a bar code reading apparatus, a laser beam emitted from a laser beam source disposed in a casing is reflected by a rotational mirror to scan a bar code. The reflected laser beam is reflected by a fixed scan mirror having four mirror members continually arranged with given angles therebetween, and the resultant beams are irradiated outward through a read window formed in the casing. Multiple scan lines in multiple directions are obtained on a normal plane to the read window. These scan lines consist of two groups of vertical scan lines in the normal plane, and two groups of oblique scan lines inclined at a given angle with respect to the horizontal direction.
