Abstract

A stage bar-code detecting apparatus is composed of host computer and computer connected by electrical box. Host computer is connected with electric engine, transmission source, probe bracket, read head bracket and longitudinal guide separately by scan platform. Longitudinal operating platform connects longitudinal and lateral guide and grating ruler brace. Probe bracket connects N-average pointer, reflectance source and adjust handle. Grating ruler brace connects grating ruler. Read head connects bracket and electrical box which is connected with doubling circuit and single chip by reversible counting circuit. Single chip connects communicating interface, analog-to-digital conversion, channel optical coupling, electrical engine and driving circuit. The device can detect printed bar-code and bar-code production acetate, has Abbe error eraser and high testing precision, can realize average measurement for one bar-code, parallel moving, data collecting, simple operation, can detect merchandise bar-code, cross two-five bar-code, logistics bar-code and 128 bar-code etc.

Description

Technical field: [0001] The invention relates to a detection device, in particular to a desktop bar code detection device, which can detect whether the strips, empty geometric dimensions, optical characteristics and bar code technical indicators of printed bar codes and bar code original films conform to national standards and the latest international standards. Background technique: [0002] With the characteristics of reliability, speed, economy and practicality, bar code technology solves the "bottleneck" problem of data input in the process of computer application. Bar code has become the "common language" in international trade and the "ID card" of international commodities. [0003] A bar code is a group of bar-space graphics with different widths and the same black and white. It uses the change of bar and space size and the difference of the two-color optical characteristics of the bar and space to carry information, realize automatic identification and automatic data ...
