An original detection apparatus includes a placing table for placing an original thereon, an openable/closable pressing member for covering the original placed on the placing table, an original detection unit, arranged below the placing table, for detecting the presence/absence of the original on the placing table, an open/closed detection unit for detecting an open/closed state of the pressing member, and a judging unit for judging whether or not the original is placed on the placing table, on the basis of an output from the original detection unit obtained when the open/closed detection unit detects that the pressing member is in an open state and an output from the original detection unit obtained when the open/closed detection unit detects that the pressing member is in a closed state.
