Abstract

A Scan head’s Aiming Beam Exposure Solution System The invention discloses a scan head’s aiming beam exposure solution system, comprising the 5 control circuit of aiming lamp.The control circuit is composed of 5 pin terminals, wherein pin 1 and 2 are the input terminal of gate circuit, and pin 4 is the output terminal of NOT gate circuit; the high level Vcc is connected with pin 5 of the control circuit, and pin 3 of the control circuit is grounded; the pin 1 and 2 are connected with the scanning signal and the field sync signal re- spectively, and resistor R1 is connected with the field sync signal and is grounded. The solution 10 system, compared with the existing scan heads on the market, can completely solve the local overexposure problem of the aiming beam, hugely improve the decoding accuracy, stability, identification rate, decoding speed and power consumption of the scan head hugely, and realize cost-effectiveness easily. 15 FIGURE 1
