1. An inspection apparatus comprising:
a conveyer configured to convey a medium having a plurality of printing areas in a conveying direction so that the plurality of printing areas are conveyed in turn in the conveying direction;
a reader configured to read images printed in the plurality of printing areas on the medium conveyed by the conveyer; and
a controller,
wherein when a plurality of images, each of which a printing position of a code in the printing area is the same as the other images, are respectively printed in the plurality of printing areas, the controller:
causes the reader to read a prescribed image printed in a prescribed printing area among the plurality of printing areas;
inspects whether the code satisfies a prescribed condition based on a read image of the prescribed image read by the reader;
acquires position information for specifying a printing position of the code from the read image of the prescribed image;
causes the reader to read an upstream image printed in an upstream printing area upstream of the prescribed image in the conveying direction;
extracts a processing range in which the code is included from a read image of the upstream image read by the reader based on the position information; and
inspects whether the code included in the processing range satisfies the prescribed condition.
