Actuation method of virtual laser barcode scanner

An actuation method of virtual laser barcode scanner, comprising:

• an indicating light source start step:
• a laser module is started and the laser thus generated is formed to a linear laser beam after passing through a fixed type refractive lens and the linear laser beam is for projecting and aiming onto a one-dimensional barcode to be read;
• a level signal confirmation step:
• after said linear laser beam is projected onto the barcode to be read, a first reflected light is generated and is received by an image pickup module which outputs a level confirmation signal to a microprocessor module after the image pickup module confirms that said linear laser beam already aligns to said one-dimensional barcode;
• an indicating light source switch-off step:
• following the above step, said laser module is switched off so that said linear laser beam is simultaneously disappeared;
• a reflected light generation step:
• said barcode generates a second reflected light from environment light source;
• a reflected light source receiving step:
• said second reflected light is received by said image pickup module;
• a decoding step:
• said image pickup module transform said second reflected light into electronic signal and conduct to a central control module so as to conduct decoding;
• a reading confirmation step:
• when said decoding step is finished, a reading confirmation light source module is actuated to generate a colored light by which operators can confirm the accomplishment of barcode reading;
• said indicating light source starting step is repeated;
• and
• the time period from the switch-off of the indicating light source to the switch-on of the same is controlled to be less than 1/16 second.
