Address detector
专利汇可以提供Address detector专利检索，专利查询，专利分析的服务。并且PURPOSE: To execute exact address detection by optically detecting the shadow of a label and detecting the attaching position and shape of the label on mail based on the information of the shadow.
CONSTITUTION: For a photoelectric conversion part 50, based on a control signal l30 from a control part 70, scanning is repeated with an A
1 as a scanning start point and finished at a B
n . At a detection point P, the shadow is generated by the thickness of a label 11 and since a photoelectric converting signal l40 goes to the shadow of the label between C and D when A
1 B
1 is scanned, an electric signal level is lowered. In a binary circuit 60, the photoelectric converting signal l40 obtained by the scanning is binarized by a value which is desired to be set in advance. A label detection part 80 detects the position or shape, etc., of the label 11 based on the binarization signal. An address detection part 90 detects the position of an address by limiting the address part to the part of the label 11 based on the left edge and right edge detection information of the label 11. Thus, the exact address detection can be executed.
