Abstract

PURPOSE:To provide a thermal head for printing wherein the connection of heating resistors with group electrodes of a common electrode is made such that m heating resistors as one unit are connected to one group electrode, and this connection pattern is repeated n times thereby an electric current is dispersed to disperse the generated heat. CONSTITUTION:Every mth heating resistor out of a heating resistor group 1 comprising mXn heating resistors R11-Rmn is connected to the common electrodes 2, a memory circuit 3 through which an electric current is selectively passed according to a memory signal of information from outside is provided to a set of heating resistors that comprises said every mth heating resistor, and when an electric source is applied to particularly common electrodes of the common electrodes, an electric curent is passed to the prescribed resistors. When the group electrodes 2b-2m are turned on, though the electric current can be passed through all the desired heating resistors, as the electric current is dispersed, the electric current passing through an MSI at a time amounts to an electric current required for only one heating resistor even when an MSI, wherein one unit comprises m bits, etc. are used for the line memory.
