In a determination necessary state in which setting of the document is not detected while an object on the document tray is detected, it is determined to execute feed reading, or to execute place reading, or to be disabled to confirm to execute the place reading or the feed reading, based on whether or not there is a document on the place-reading contact glass and based on history information. |
