• a second reading mode in which a reading continuation instruction is not accepted from the user after the reading section has read the document,
• a reading target determination process for determining whether a document placed on the sheet feed tray is a reading target or a document placed on the document base is the reading target,
• a document reading process for, based on a reading start instruction from a user, causing the reading section to read the document that was determined to be the reading target in the reading target determination process, and
