Abstract
A barcode reader is provided, able to turn on/off power or scanning function by itself according to use condition. The main structure thereof comprises a light source module, image sensor, information transferring device, and sensing device, wherein the sensing device is used to sense whether the light signal received by the image sensor changes during an interval of time and control on/off of the power or scanning function of internal elements in the barcode reader according to the change of the light signal. This way, not only the convenience in use can be raised, but also an object of saving energy and increasing lifetime of the barcode reader can be achieved.
Claims16
A barcode reader, comprising:
- a light source module for generating a scanning light to scan a barcode, and automatically generating a reflection barcode signal after scanning said barcode;
- an image sensor provided at a back end of said light source module for receiving and processing one of said reflection barcode signal and an incident light source signal from external input;
- a data transferring device provided at a back end of said image sensor for transferring said barcode signal processed from said image sensor to an information system;
- and
- a sensing device fixed in said barcode reader for sensing change of said incident light source signal during an interval period, as well as a dependence for said barcode reader operation power on/off.
