1. An image reading apparatus comprising:
a document tray;
a common transport route;
a first transport route and a second transport route branched from the common transport route;
a switching device provided at a branch point between the first transport route and the second transport route, and configured to guide the document from the common transport route, to one of the first transport route and the second transport route;
a document transport device that draws out the document placed on the document tray therefrom, transports the document through the common transport route, and delivers the document transported from the common transport route, to one of the first transport route and the second transport route, via the switching device;
a first image sensor that reads an image on a first face of the document being transported through the first transport route;
a second image sensor that reads an image on a second face of the document being transported through the common transport route;
a first discharge tray that receives the document delivered from the first transport route;
a second discharge tray that receives the document delivered from the second transport route; and
a control device including a processor, and configured to act, when the processor executes a control program, as:
a controller that executes one of a first simplex reading mode including causing the switching device to guide the document from the common transport route to the first transport route, causing the first image sensor to read the image on the first face of the document, and discharging the document to the first discharge tray, and a second simplex reading mode including causing the second image sensor to read the image on the second face of the document, causing the switching device to guide the document from the common transport route to the second transport route, and discharging the document to the second discharge tray;
decides whether the document may be discharged to the first discharge tray, and whether the document may be discharged to the second discharge tray; and
inhibits the first simplex reading mode, upon deciding that the document should not be discharged to the first discharge tray, and inhibits the second simplex reading mode, upon deciding that the document should not be discharged to the second discharge tray,
wherein the controller is configured to:
execute a duplex reading mode including causing the second image sensor to read the image on the second face of the document, causing the switching device to guide the document from the common transport route to the first transport route, causing the first image sensor to read the image on the first face of the document, and discharging the document to the first discharge tray;
inhibit the duplex reading mode, upon deciding, during execution of the duplex reading mode, that the document should not be discharge to the first discharge tray, and execute the second simplex reading mode including causing the second image sensor to read the image on the second face of the document, and discharging the document to the second discharge tray by causing the switching device to guide the document from the common transport route to the second transport route; and
again execute, when a user places the document discharged to the second discharge tray on the document tray, with front and back faces reversed, the second simplex reading mode including causing the second image sensor to read the image on the first face of the document, the front and back faces of which have been reversed, and discharging the document again to the second discharge tray, by causing the switching device to guide the document from the common transport route to the second transport route.
