A switch controller(120) controls the first switch. The second switch(150) makes the light receiving parts output the output signals sequentially and repeatedly for the predetermined time. A signal processor(160) processes/outputs the output signals inputted from the second switch. A controller(110) distinguishes the sort of the optical disc depending on a time interval between the signal reflected from a surface of the optical disc and the signal reflected from a data recording layer.
