Patent ID: 7350706

Claim:
A transmission and reception apparatus for transmitting and receiving a command to and from a first non-contact-type data communication apparatus and a second non-contact-type data communication apparatus and a contact-type data communication apparatus, the transmission and reception apparatus comprising: a transmission path for transmitting an electrical signal, to which one or more of the contact-type data communication apparatuses are connected electrically; generation means for generating a first transmission command for controlling the contact-type data communication apparatus; first relay means for relaying a first transmission command from the generation means and a first reply command from the contact-type data communication apparatus and from the first non-contact-type data communication apparatus with respect to the first transmission command between at least one of the contact-type data communication apparatus and the first non-contact-type data communication apparatus, and the generation means via the transmission path, wherein the first relay means relays the first transmission command and the first reply command by transmitting and receiving a coded signal, such that the first transmission command and the first reply command are coded by a coding method, the coding method being associated with the first non-contact-type data communication apparatus, to and from the contact-type data communication apparatus via the transmission path; and second relay means for relaying a second transmission command for the contact-type data communication apparatus, which is transmitted in the form of radio waves from the second non-contact-type communication apparatus, and a second reply command with respect to the second transmission command from the contact-type data communication apparatus between the other data communication apparatus and the contact-type data communication apparatus via the transmission path, wherein the second relay means relays the second transmission command and the second reply command by transmitting and receiving a coded signal, such that the second transmission command and the second reply command are coded by a coding method, the coding method being associated with the second non-contact-type data communication apparatus, to and from the contact-type data communication apparatus via the transmission path.
