Abstract
An area setting device for setting coordinates of two points in a diagonal direction in one or more areas to be copied by a photocopier utilizing key operation in sequence, in which different colors are used for coordinate display in each direction. The same colors as the coordinate displays are used for coordinate input indicators. All the points are memorized as to whether coordinates have been applied. A key input is accepted for the first point not having coordinates applied, and this converts the memorized condition. Key input acceptance and memory state conversion are repeated for all the points required.
