Claim:
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.
