Abstract:
1. A feeder device for feeding media sheets one after another along a feed path, comprising: (a) an accommodator capable of accommodating the media sheets stacked therein; (b) a feed mechanism including (b- (c) a detector configured to detect an amount of rotation of one of said roller and said electric motor; (d) a controller configured to adjust said variable on the basis of the amount of rotation detected by said detector such that feed movement of each of the media sheets along said feed path can be achieved substantially as desired; (e) a monitor configured to monitor an actual value of said variable that is adjusted by said controller; and (f) a media-related information obtainer configured to obtain information related to the media sheets fed by said feed mechanism, based on the actual value of the adjusted variable monitored by said monitor, wherein said media-related information obtainer includes a media-type determiner configured to determine a type of the media sheets fed by said feed mechanism, based on the actual value of the adjusted variable monitored by said monitor.
