Abstract
A digital multi function peripheral includes a scanner for reading an image in a document read position; a document retaining cover for being able to change an opening and closing state between a state in which the scanner is closed and a state in which the scanner is opened, and conveying a document to the scanner when the scanner is closed; a registration sensor for detecting a leading end portion and a rear end portion of the document conveyed by the document retaining cover; and a controller for determining the opening and closing state of the document retaining cover based on a state of the leading end portion and the rear end portion of the document in the image read by an IR module at a time when a predetermined time frame elapses since a detection state of the registration sensor changes. Therefore, the opening and closing state of the conveyance unit for conveying the document can accurately be detected.
