Abstract
A thermal recording apparatus has a thermal recording head constituted by heating elements disposed in parallel, a driver circuit actuated in response to a recording signal, and a control circuit which controls the driver circuit. The apparatus is arranged such that, when data in a memory which stores recording data to be output to the control circuit is transferred to a register in the driver circuit, an address signal for reading out the recording data in the memory is output to the driver circuit simultaneously with the recording data in the memory, thereby selecting a register in the driver circuit.
