Rotatable sheet supplying cassette and associated controller which may prevent rotation for certain sized sheets

摘要

A sheet supplying device supplies a sheet to a sheet supplied apparatus which has a predetermined maximum size of the sheet capable of being supplied thereto. The sheet supplying device includes a movable cassette for placing the sheet thereon and movable to at least two transport positions so as to transport the sheet therefrom to the sheet supplied apparatus in at least two transparent directions, and a driving device, to which a driving order is given, for moving the movable cassette to at least two transport positions in response to the driving order. The sheet supplying device further includes a control device, to which the size of the sheet placed on the movable cassette is input, for stopping the driving motion of the driving device prior to the driving order if the input size of the sheet exceeds the maximum size when the movable cassette is moved.
