1. An image reading apparatus comprising:
a reading unit that reads an original document;
an original document placing portion on which the original document is placed;
a feeding roller that feeds the original document from the original document placing portion;
a separating roller that is a roller nipping the original document between the feeding roller and the separating roller and is capable of switching between a separation state in which the original document is separated and a non-separation state in which the original document is not separated;
a switching unit that switches between the separation state and the non-separation state;
a double-feeding detecting portion that detects double-feeding of the original document on the downstream side of the feeding roller;
a sensor which detects whether or not the original document is present or absent on the original document placing portion is provided on the original document placing portion;
a touch panel that performs both displaying and inputting; and
a controller that controls feeding of the original document, the controller detects a first feeding mode and a second feeding mode, the first feeding mode is a mode in which a state of the separating roller is set to the non-separation state and the original document is fed, the second feeding mode is a mode in which the state of the separating roller is set to the separation state and the original document is fed,
wherein the controller does not detect the double-feeding by the double-feeding detecting portion in the first feeding mode and detects the double-feeding by the double-feeding detecting portion in the first feeding mode,
wherein the first feeding mode is a feeding mode in which only one sheet of the original documents set in the original document placing portion is fed and a feeding standby state is set until a next sheet of the original documents is set,
wherein the second feeding mode is a feeding mode in which a plurality of original documents set in the original document placing portion is separated by the separating roller and is continuously fed,
wherein the controller displays a guide of reading at the touch panel when the feeding and reading of original documents is started in the second feeding mode and does not display the guide of reading at the touch panel when a reading of original documents is finished in the second feeding mode, and
wherein the controller displays a guide for setting of next original documents in position for reading at the touch panel when the reading and feeding of original documents is finished after starting the feeding of original documents in the first feeding mode.
