Abstract:
1. An attachable member-recognition device comprising: an attachable member in which an information-engraved section having a predetermined shape is formed; an attachment section to which the attachable member is detachably attached; a deformable section which is provided on the attachment section and which is configured to slide on the information-engraved section of the attachable member to deform when the attachable member is attached to the attachment section; a stress light-emitting portion which is provided with the deformable section and which receives a force, when the deformable section slides on the information-engraved section, to emit a light, an intensity of the light depending on the shape of the information-engraved section; and a light-receiving sensor which receives the light emitted by the stress light-emitting section and which generates a recognition signal corresponding to the shape of the information-engraved section, wherein the stress light-emitting portion is provided in the deformable section at a portion at which a stress is most concentrated when the deformable section is brought into contact with the information-engraved section and causes the force to be received by the stress light-emitting portion.
