Abstract
The utility model relates to a barcode scanner for detecting and scanning dual purpose, comprising a control device which drives a detecting light source through an image sensing driving device to drive the detecting light source to give off the detecting light to detect and scan the bar code. An image sensor can receive the reflected light to create a sensing signal which can obtain a fourth signal by the process of an amplifier, a tracker, a comparator and a code converter. The fourth signal is transmitted to the control device to judge weather the light is the signal of the bar code. If the fourth signal is a complete bar code signal, the control device transmits the fourth signal to a computer system. When the fourth signal is a broken bar code signal, the control device may drive a scan light source through the image sensing driving device to emit scan light to the bar code. The scan light can be reflected to the image sensor through the bar code to scan the bar code. The utility model can reduce the usage cost of the bar code system and the occupied volume.
