Abstract

A medium transport device includes a transport section transporting a medium in a contact manner, an electrode detecting static electricity charged on the medium, and a static electricity detection circuit. The static electricity detection circuit includes a voltage clamp circuit clamping a detection signal input from the electrode to a predetermined voltage, an amplifier circuit amplifying an output signal of the voltage clamp circuit, a rectifier circuit rectifying an output signal of the amplifier circuit, and a comparator circuit serving as a determination circuit determining whether the medium exists based on an output signal of the rectifier circuit.
