FUNCTIONAL DEVICE, ACCESS APPARATUS, ACCESS SYSTEM, AND COMMUNICATION ESTABLISHING METHOD
First Claim
1. A functional device capable of communicating with an access apparatus, the functional device comprising:
- an access controller that controls an additional device and obtains characteristic information of the additional device at an initialization process of the additional device;
a memory that stores the obtained characteristic information;
a communication unit that transmits and receives data to and from the access apparatus; and
a communication controller that transmits the characteristic information stored in the memory to the access apparatus, when receiving a request for the initialization process from the access apparatus through the communication unit after transferring an exclusive right to the access apparatus, the exclusive right being a right to exclusively control the additional device.

8. A communication establishing method in which a functional device capable of communicating with an access apparatus establishes communication between the access apparatus and the functional device, the method comprising:
-
controlling an additional device to obtain characteristic information of the additional device at an initialization process of the additional device; storing the obtained characteristic information; transmitting and receiving data to and from the access apparatus; and transmitting the stored characteristic information to the access apparatus, when receiving a request for the initialization process from the access apparatus after transferring an exclusive right to the access apparatus.
