摘要	The present invention relates to a laser diode driving circuit for supplying a drive current to a laser diode, a semiconductor integrated circuit for driving the laser diode, and an image recording apparatus in which a step of executing a scanning on a predetermined member to be scanned with a laser beam holding image information is included in an image recording step. The laser diode is certainly kept in a no light emitting state at a timing when the laser diode should be kept in the no light emitting state and is allowed to emit a laser beam of the light quantity faithfully corresponding to the drive current at a timing when the drive current is supplied to the laser diode. A bias current out of the bias current and a drive current which are supplied to a laser diode 1 is further divided into a first bias current and a second bias current. Normally, only the first bias current is supplied to the laser diode. The second bias current is supplied and stopped in a manner similar to the drive current.
其他摘要	本发明涉及一种用于向激光二极管提供驱动电流的激光二极管驱动电路，一种用于驱动激光二极管的半导体集成电路，以及一种对要扫描的预定构件执行扫描的步骤的图像记录装置利用激光束保持图像信息包括在图像记录步骤中。在激光二极管应保持在无发光状态的时刻，激光二极管当然保持在不发光状态，并且允许激光二极管在时刻发出忠实地对应于驱动电流的光量的激光束。驱动电流提供给激光二极管。提供给激光二极管1的偏置电流和驱动电流中的偏置电流进一步分为第一偏置电流和第二偏置电流。通常，仅将第一偏置电流提供给激光二极管。以与驱动电流类似的方式提供和停止第二偏置电流。
