A solenoid driving apparatus includes at least two solenoids of which driving periods do not overlap, a driving unit for driving each solenoid, and a signal generating unit for giving the driving unit a control signal information of each solenoid. The driving unit includes circuit sections jointly used with regard to the driving of each solenoid, and drives each solenoid based on the control signal information corresponding to each solenoid. The signal generating unit generates the control signal information of each solenoid which is given to the driving unit based on the drive pulse signal corresponding to each solenoid. Also, while a control signal information is given to the driving unit based on the drive pulse signal corresponding to one solenoid, the signal generating unit does not accept the input of any drive pulse signal even when a drive pulse corresponding to the other solenoid is generated by a noise. Thereby, malfunctions and adverse effects on the driving apparatus due to the simultaneous use of common circuit sections of the driving unit for driving more than one solenoid can be prevented.
