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.

摘要： A signal is read from photodiodes periodically with a predetermined period and applied to the input terminal. The input signal is amplified by an amplifier circuit and switched by a signal switching circuit to be alternately input to two offset cancel circuits through their respective switching elements. The period with which the switching elements are periodically turned on is set to be virtually double the period in the outputting of the signal from the photodiodes. The periods of time at which the switching elements are alternately turned on are shifted virtually half the period from each other. Further, output signals from the offset cancel circuits are adapted to be alternately output through a multiplexer.
