The circuit 2 is branched into a market price information circuit 2' by a distribution device 3. The circuit 2' is extended in a nationwide network. A user can leads the circuit 2' into his/her room and connects it to a local information terminal control device 7 which is connected to a local information terminal 10 via a network controller 8 and a subscriber telephone network 9. A single device 7 can control plural terminals 10. Then the device 7 receives all market price information sent from the device 1 to store them and at the same time prepares for the service requests given from the terminals 10.
