An amplifier is provided for amplifying the electric signal converted by the photoelectric device. A gain adjusting device is provided for adjusting a gain of the amplifier such that a summit level of the electric signal can be raised to a predetermined upper limit level. A digitizing device is provided for converting the electric signal amplified by the amplifier into a binary signal, using a predetermined level.
