A cup lid dispenser is characterized by a cylindrical housing for containing a stack of relatively flexible cup lids in vertical orientation with a lip of the bottommost lid supported at points around its circumference on a plurality of shelves within and around a base of the dispenser at a lower end of the housing. The auxiliary conductive patterns can be substituted by conductor sections which are provided in the insulating sheets at the positions facing the through-holes provided in adjacent insulating sheets. Compressed code is entered for the programs to be blocked. The azimuth sensor unit senses sunlight to generate an azimuth signal. The identification code does not disclose the identification string, but is able to confirm the accuracy of the identification string and selectively correct a given number of bits within a corrupted identification string.
