The present invention relates to a memory array having a plurality of memory cells. According to said method, air is blown transversally to the yarn treatment channel. Optical black data from an OB area on the imaging surface is transferred in the left direction by the horizontal transfer path and outputted from one output circuit as total OB data. The labelerprinter can be easily loaded with label and webs of different widths. The first select switch outputs the first storage voltage as the first output voltage according to the first control voltage. A rechargeable lithium battery using tin or tin-alloy as the anode active material.
