Abstract
PURPOSE: To maintain the signal transmission although the handset is hooked on by retrieving the state of connection of the information center after calling and then holding the connection state.
CONSTITUTION: When the information is called out via the telephone set for connection, the change of the voltage occurred at telephone circuit 3 is detected by talking state detector 14. And relay switch 10 is closed, and signal conversion part 7 is connected to cirlcuit 3. Under these conditions, the signal transmission can be maintained between the information center and part 7 although the handset is hooked on. At the same time, part 7 supplies the character/picture information sent from circuit 3 to TV picture receiver 9. And when the necessary reception is over, the information end signal transmitted from the information center is detected through information end signal detector 12, and the connection is released between part 7 and circuit 3.
