An image input/output apparatus is capable of image printing and reading with simple controls, and a cartridge reads an original with a simple control. When a removable printhead or image reading head is attached to a common carriage to print an image on a print medium or read an original, a flip-flop in an image processing IC inputs a printing period signal, and generates a reading period signal to control a reading operation in synchronization with an internal clock of a scanner unit. A line sensor is controlled based on the generated reading period control signal.
