1. A reading device comprising:
a plurality of transport rolls that transport a document along a transport path, include a discharge roll disposed on a most downstream side of the transport path, and rotate and do not rotate in synchronization with one another;
an opening and closing unit that exposes or covers an upstream portion of the transport path;
a plurality of detectors that are provided apart from one another along the transport path, detect a transported document, and include a discharge detector that is disposed on a most downstream side of the transport path and is disposed on an upstream side relative to the discharge roll in a document transport direction;
a reader that reads an image formed on a transported document in a downstream portion of the transport path; and
a controller that stops the plurality of transport rolls once upon occurrence of a document jam inside a device body by controlling the transport rolls and rotates the transport rolls for only a predetermined period in a case where the discharge detector is detecting no document and a length of a document is equal to or longer than a threshold length.
