    • An electronic document management system includes an electronic document management unit that manages a correlation between address information that is printed on a surface of a medium to specify a position of the surface of the medium and an electronic document printed on the medium, and an accumulating unit that accumulates correction information describing a difference between a position of the electronic document on a document image and a position on the medium by a code image describing the address information printed on the surface of the medium together with the electronic document, in connection with the medium. The electronic document management unit inputs reading information of the code image, and corrects position information obtained from the reading information based on the accumulated correction information so that a position of the electronic document on the document image matches with a position on the medium by the code image.

    • An amplifier unit is provided, with which the need for manufacturing a photoelectric conversion IC in Bi-CMOS process is eliminated, and relatively low process cost of the photoelectric conversion IC is achieved. The input section of a buffer (the base of a transistor Q5) is connected with a plurality of patterns of phase compensation circuits each including a resistor and a capacitor connected in series. A bipolar transistor (Q6) is interposed between a positive power supply line and a capacitor (C2) forming a capacitance of the phase compensation circuit. By switching on/off the bipolar transistor (Q6), the capacitance value and resistance value of the phase compensation circuit are switched. Since the bipolar transistor (Q6) is interposed between the capacitor (C2) and the positive power supply line, base current (Isw) acting as a switch signal does not affect the amplifier unit.
