The invention relates to a design patent file cover with a bar code based on a
scanner utilizing solar photovoltaic power supply, and belongs to the technical field of
new energy application. The current generated by irradiating a
solar cell with
sunlight is input to a controller through a conductive line for adjusting and then charges a
lithium ion cell installed in a charger, the
lithium ion cell is installed in a bar code
scanner for supplying power, the bar code on the design patent file cover is scanned by the bar code
scanner, the bar code comprises the information of a recording
list of the
patent document in the design patent file cover, the bar code scanner receives reflected
light irradiation generated by scanning, the reflected light is converted into an
electric signal in an optoelectronic converter, the
electric signal is input to a translator to distinguish bar and blank information, a sending antenna sends the information to air, a receiving antenna receives the information and outputs the information to a computer for
processing, the processed result is displayed on a display, and the recording
list of a submitted
application document and a recording
list of a submitted appended document in the design patent file cover are printed by a printer.
