Medium handling device, medium handling program, and medium recognition reference information creation system

A medium handling device comprising:

• a storage means that stores a single or a plurality of medium recognition reference information;
• a recognition means that uses the medium recognition reference information to recognize a state of a target medium;
• and
• a setting means that, when medium recognition reference information that is new is stored in the storage means, sets use of the new medium recognition reference information as either valid or invalid, wherein
• when the setting means has set valid, the recognition means uses the corresponding new medium recognition reference information to recognize a state of the medium.

A medium recognition reference information creation system comprising:

• a first system including a first medium handling device and a reference information generation device;
• and
• a second system that is separate to the first system and that includes a second medium handling device and an authentication device, wherein:
• the reference information generation device of the first system detects characteristic information about introduced medium and generates medium recognition reference information for the medium;
• and
• the second medium handling device of the second system uses the medium recognition reference information generated by the reference information generation device and the medium characteristic information to evaluate a quality of the medium recognition reference information;
• the authentication device of the second system generates authentication information corresponding to the medium recognition reference information evaluated by the second medium handling device;
• and
• the first medium handling device of the first system includes
• a storage means that stores a single or a plurality of medium recognition reference information,
• a recognition means that uses the medium recognition reference information to recognize a state of a target medium, and
• a setting means that, when new medium recognition reference information that has been evaluated by the second medium handling device and authentication information corresponding to the new medium recognition reference information are stored in the storage means, sets use of the new medium recognition reference information as either valid or invalid, wherein
• when the setting means has set valid, the recognition means uses the corresponding new medium recognition reference information to recognize a state of the medium.
