A medium transport apparatus includes a controller that determines how many transport roller pairs disposed on a medium transport route are transporting a medium, based on detection information from detectors disposed in relation to respective transport roller pairs. Then, the controller sets a threshold to a larger value as a larger number of transport roller pairs are transporting the medium and sets the threshold to a lower value as a smaller number of transport roller pairs are transporting the medium.

Systems and methods for detecting the presence of metallic objects in media to be conveyed in a medium transport system are disclosed. One or more induction sensors are included in the medium transport system to detect the presence of metal in the transported media, with detection signals sent from the sensors to a system processing unit. An ultrasonic detector is employed in some embodiments to output another detection signal. One or more microphones may also be included, for detecting the sound created as the medium is being transported. The system processing unit analyzes various detection signals and analyzes computed sound values from the microphones, to determine the presence and location of metal in the media. A position jam detector may assist in determining jams of the media along the medium transport path.

A conveyor includes a conveyance roller to convey a conveyed object, a pair of roller supports opposing to each other and supporting both ends of the conveyance roller in an axial direction thereof, a position sensor to detect a position of the conveyed object, and a sensor support supporting the position sensor.
