Abstract

PURPOSE:To provide a cordless telephone set with both a secret talk function and three-party calling function, by providing a means of disconnecting another station when its station is engaged with line wires and another means of disabling the means to operate at its station. CONSTITUTION:A master station is provided with transmitter-receiver 1 and connected to a subordinate station by radio. When the master station is connected to line wires L1 and L2, lifting its receiver excits relay RY-6 to disconnect the circuit from the subordinate station. When the subordinate station is connected to the line wires, answer signal f2 is transmitted through the operation of an answer switch and relay RY-6 of the master station is changed over to disconnect the circuit from the master station, enabling secret talk communication. For the three-party communication of the master and subordinate stations with the line wires, tone signal f3 is sent out through the closure of the interphone switch of subordinate station to perform the communication without opening gate A1 of the master station. After transfer switch 26 of the master station is operated twice to release the holding state, FF is set and relay RY-7 is excited to disable to RY-6 to operate, so that the three- party communication.
