英文摘要PURPOSE:To emit a laser light having excellent extinction ratio by controlling a bias current applied when the light of a semiconductor laser is extinguished on the basis of a threshold bias current value and applying the bias current of the degree not laser oscillating near the threshold value to the laser. CONSTITUTION:When a controller 5 calculates nonlight emitting bias current value IBIAS, it is applied to a semiconductor laser The controller 5 feeds data for increasing a light emitting current to a latch 8 until a predetermined emitted light quantity is obtained. The controller 5 holds the value at the latch 8 and instructs a laser OFF signal to a switching circuit 3. Thus, only the value IBIAS is applied to the laser 1 to become capable of printing. It becomes possible to print by the above operation, the controller 5 then generates a laser ON signal LON on the basis of a print signal, and the laser 1 emits a light in response to the input print signal on the basis of the current in which a light emitting current is added to the bias current.
