Abstract
A device enabling simple detection of a recording medium placed on a tray includes at least two electrodes arranged on the tray, an electric field sensor connected to the electrodes, and a control circuit connected to the electric field sensor. The electric field sensor detects capacitance in accordance with the distance between the electrodes relative to the recording medium placed on the tray. The control circuit determines the recording media type of the recording medium based on the capacitance detected by the electric field sensor.
