Abstract: A copying machine having an original feeding unit for feeding originals onto a platen glass which is operable in a two-original feeding mode where two originals are placed side by side in a particular position on the platen glass, and a sheet handling unit which is operable in a binding mode where copy sheets which copied images are bound. When the two-original feeding mode is selected, a selection of the binding mode is inhibited. When the two-original feeding mode is selected after the binding mode was selected, a warning is generated to inform that the sheet handling unit becomes impossible to be operated in the binding mode. When a copying operation is started without in spite of the generation of the warning, the binding mode is canceled.

Abstract: An image forming apparatus provided with a plurality of sheet supply inlets respectively accommodating different kinds of sheets and a selecting member for selecting a desired kind of sheets. When a desired kind of sheets is selected by the selecting member, a check is made to determine whether the presently selected sheets are the same kind, for example, the same size, as the sheets which have been selected prior to the operation of the selecting member. When the presently selected sheets are the same kind as the sheets selected prior to the operation of the selecting member, the apparatus is controlled so that a sheet supply inlet accommodating the same kind of sheets as the sheet selected prior to operation of the selecting member but different from the sheet supply inlet used for sheet supply prior to the operation of the selecting member, for example, a sheet supply inlet in which the same kind of sheets are oriented in a different direction, is selected.
