Abstract: PURPOSE:To prevent misoperations, by causing an on-hook dial state to be set when another switch is operated in case where no detection output is obtained at a detection circuit. CONSTITUTION:When a switch 52A is again depressed while calling the tele phone of a caller a contact point 22 is set to its off state and a waiting state is set thereafter and, if the caller is absent, the call can be cancelled by depress ing the switch 52A again. Since the switch 52A can also be used as an answering switch when responding to a call with an answering message at the time of the call and an on-hook dial switch, the control panel of this system can be simplified and margins can be obtained in the arrangement, size, design, etc., of each kind of operation switch. Moreover, everything goes through when handsets 13 and 24 are lifted up when the caller can be confirmed by depressing the switch 52A, even if the switch 52A is used as the answering switch or on- hook dial switch. Therefore, the operability of this telephone equipment is improved and misoperations can be prevented.

Abstract: PURPOSE:To increase the function of a communication device, by transmitting and receiving the synthetic voice corresponding to each time supplied from a timepiece device via a radio device. CONSTITUTION:When switches 22 and 23 are turned on, the synthetic voice corresponding to each time given from a timepiece device 2 is delivered from a speaker via a mike amplifying circuit 16 and a low-frequency amplifying circuit 10 in the reception time and then transmitted from an antenna 5 via a transmitter 18 in the transmission time, respectively. At the same time, a desired time is set previously by means of a timer of the device 2. A power supply switch 4 is automatically turned on by a control signal given from the device 2, and the power supply is applied to a radio device. At the same time, switch 24 is turned on to deliver the synthetic voice given from the device 2 from the speaker 11 via the circuit 10.
