Abstract
A current control device for controlling, on the basis of a current command value input from an external device, a light-emitting unit current flowing from a power supply device to a light-emitting unit that includes one or a plurality of laser diodes, includes: a switching element coupled in parallel to the light-emitting unit; and a pulse-width-modulation control circuit unit to provide pulse width modulation control of the switching element in a case in which an output current output from the power supply device is greater than a present current command value or a next current command value upon a start of supply of, upon a termination of supply of, or during supply of, the light-emitting unit current.
