摘要： Disclosed is a thermal head comprising: plural heating elements, and a driving circuit element comprising plural switching elements connected individually to the heating elements, gate elements connected individually to the switching elements, and a shift register connected to the gate elements; wherein the plural heating elements are divided into plural blocks, and the gate elements of each block are connected to plural shift registers in the same number of bits as the number of heating elements of each block individually; strobe signals in the same number as the number of divisions of the block are fed into gate elements corresponding to each block; a clock gate element is provided in each block in order to obstruct clock input into the shift register corresponding to each block when printing of each block is active; and each block is further divided into plural small blocks, and the heating elements corresponding to each small block are disposed in every different block.
