Abstract
An ink cartridge is formed with an information-engraved section formed to have a predetermined shape. A cartridge-attachment section, to which the ink cartridge is attached, includes a deformable section, a stress light-emitting section which emits light depending on the shape of the information-engraved section by means of a stress received when the deformable section makes contact with the information-engraved section, and a light-receiving sensor which receives the light emitted by the stress light-emitting section to generate a recognition signal corresponding to the information-engraved section. An attachable member-recognition device is provided, which has a relatively cheap and simple structure, which is capable of setting information about an attachable member including, for example, the ink cartridge and a printing paper tray, and which is capable of recognizing the information.
