LED PRINTER

PURPOSE: To provide an LED printer in which the print image when an oblique line is printed can be made smooth. CONSTITUTION: The LED printer comprises a plurality of LEDs 60 arranged on a line, means for transferring a plurality of data signals DATA1, DATA2 in synchronization with the same transfer clock CLK1, a plurality of shift registers 22, a plurality of latched circuits 26, and a plurality of driving circuits 29 for flashing the common LED 60 according to the data held in the circuit 26. Each circuit 29 has transistors Tr1, Tr2 to be turned ON, OFF corresponding to the signals DATA1, DATA2 and resistors R1, R2 for setting currents flowing to the LED 60 by the ON, OFF of the transistors Tr1, Tr2. The current set by the resistors R1, T2 flows to the common LED 60.
