PROBLEM TO BE SOLVED: To securely change over a hook switch when a handset is returned to a main body by connecting the rotary support of a handset receiver, which operates by the dead weight of the handset, and a rotary support loaded on a substrate with a connection arm and operating the hook switch with the rotary operation of the handset receiver. SOLUTION: A handset receiver 7 has a rotary support 73 on a substrate 6 and a rotary support 72 at the other end of a connection arm 71 and it is connected to a reception face receiver 75 and a transmission face receiver 76. When a handset 3 is mounted on the handset receiver 7, the connection arm 71 turns with the rotary support 72 and the rotary support 73 as supports by the dead weight of the handset 3, the reception face receiver 75 and the transmission face receiver 76 move and depress the handset 3 and a hook switch presser 74 depresses a hook switch 5 on the substrate 6. Thus, the hook switch 5 is changed over. Since the form of the reception face receiver 75 and the transmission face receiver 76 of the handset receiver 7 can freely be constituted, they can be made into the arbitrary forms by which the handset 3 can easily be received and it can easily taken up.
