Claims

[Scope of utility model registration request]

A thermal head configured by dividing heating elements for one printing line by a plurality of partial matrices in which heating elements are provided at each intersection of a vertical column and a horizontal row, and in which each 'line of either the vertical column or the horizontal row is divided according to data. are connected to the first current drive circuits to be driven, and are obtained by dividing the number of columns or rows of the other of the columns or rows by the time required to print one line by the time required to drive the heating element. A thermal head comprising a plurality of partial matrices which are connected in parallel by each line of the column or row being connected in parallel to a corresponding second current drive circuit through a diode. .
