Document conveyance apparatus and image forming apparatus

A document conveyance apparatus comprising:

• a document conveyance section configured to feed a document to a document conveyance path and convey the document along the document conveyance path;
• a cover attached to an apparatus body so as to be openable and closable and configured to cause, when being opened, an inner side of the document conveyance path to be exposed;
• an opening and closing detection sensor configured to cause an output value to change in accordance with opening and closing of the cover;
• a document detection sensor that is a sensor that detects reaching of the front end of the document and passing of the rear end thereof in the predetermined position of the document conveyance path and that is configured to cause an output value to change in accordance with whether or not there is the document in a predetermined detection position on the document conveyance path and that is a sensor configured to output, when the cover is not completely closed, a value indicating that there is the document;
• a control section configured to detect opening and closing of the cover on the basis of the output value of the opening and closing detection sensor and detect whether or not there is the document in the predetermined detection position on the basis of the output value of the document detection sensor, and
• a report section configured to report an apparatus state,
• wherein, if, when the output value of the opening and closing detection sensor has changed from a value indicating an opened state of the cover to a value indicating a closed state thereof, the output value of the document detection sensor is a value indicating that there is the document, the control section detects a half-closed state where the cover is not completely closed,
• in a case where the cover is opened because of the occurrence of a jam, if, when the output value of the opening and closing detection sensor has changed from a value indicating an opened state of the cover to a value indicating a closed state thereof after the occurrence of the jam, the output value of the document detection sensor is a value indicating that there is the document, the control section causes the report section to report that there is a probability that the document remains in the document conveyance path, and
• the report section reports that the cover is in a half-closed state at the same time as reporting that there is a probability that the document remains on the document conveyance path.
