Title:
BAR CODE POSITION IDENTIFICATION DEVICE AND COMPUTER PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/104551
Kind Code:
A1
Abstract:
The present invention provides a device and computer program that make it possible to more quickly identify the position of a bar code to be read, even when using a rotary drive mechanism in which the rotation angle of a target cannot be accurately known. A control unit 3: controls a rotary drive unit 1 and a bar code reader unit 2; in a first operation, identifies the position of a first region, which is a rough range of a bar code to be read, by a bar code scan at a faster first speed; then, in a second operation, scrutinizes just the first region by a bar code scan at a slower second speed; and identifies the position of a second region, which is a precise range of the bar code to be read. Further, the center part of the second region may be identified and rotated until reaching the reading position of the bar code reader unit.
