Abstract
A contact member swingably moves about a swing axis to contact a recording medium stacked on a medium tray, and shifts to different states depending on volume of medium. A controller performs: a detection process of detecting the stacked volume based on signals of M times outputted from the sensor, the M times being a number of times that is larger than or equal to two times; a stack determination process of determining whether the recording medium is stacked on the medium tray based on signals of N times, the signals of N times being a part of the signals of the M times outputted from the sensor, the N times being a number of times that is smaller than M; and a sheet feeding process of controlling the feed roller to feed the recording medium, in response to determining that the recording medium is stacked on the medium tray.
