Abstract

본 발명은 자동수신 전화기에 관한 것으로, 국선에 링신호가 인가되면 링신호 검출부에서 링신호를 검출하여 CPU로 입력하고 CPU에서는 이 링신호를 확인한후 수신모드선택스위치의 온/오프 상태를 읽어서 자동수신 모드로 선택된 경우에는 링신호가 울린 후 일정시간이 경과하게 되면 CPU에서 발생된 제어신호에 따라 훅스위치를 온시켜 국선을 점유하고 퉁화로 선택스위치를 스피커폰회로로 연결함으로써 사용자가 수화기를 들거나 온/오프버튼을 눌러서 통화할 필요없이 자동으로 스피커폰을 통하여 통화가능한 자동수신전화기이다.The present invention relates to an automatic receiving telephone. When a ring signal is applied to a trunk line, the ring signal detecting unit detects the ring signal and inputs it to the CPU. The CPU checks the ring signal and then reads the on / off state of the reception mode selection switch. If the reception mode is selected, when a certain time elapses after the ring signal is sounded, the hook switch is turned on according to the control signal generated by the CPU to occupy the trunk line, and the selection switch is connected to the speakerphone circuit by the speaker. It is an automatic receiving phone that can call through speakerphone automatically without pressing / off button.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 의한 자동 수신 전화기의 구성도.1 is a block diagram of an automatic receiving telephone according to the present invention.

제2도는 제1도에 의한 자동 수신 전화기의 동작 흐름도.2 is an operational flowchart of the automatic receiving telephone according to FIG.

Claims

In the telephone, a CPU (2) for controlling the operation of the entire system, and a ring signal detection unit for detecting a ring signal connected to the trunk line and the CPU (2) and inputting information thereof to the CPU ( 1), a hookswitch circuit 3 for detecting an on / off state of the handset under control of the CPU 2, and a speech network 4 for transmitting a user's voice through a call when the handset is in an off state; A voice selection switch (5) for transferring the voice stored in the speech network (4) to the speakerphone or the handset under the control of the CPU, a speakerphone circuit (6) connected to the microphone and outputting the voice of the caller, and the user The reception mode selection switch 7 in the CPU 2, having a reception mode selection switch 7 for selecting whether to select an automatic reception function or a function to perform the same operation as a normal telephone. When the switch is in the off state by determining the on / off state, the call is made by talking to the handset. When the switch is in the on state, the ring signal is stopped when a certain time has elapsed after the ring signal is generated. Hump the switch to occupy the trunk line and the telephone line selection switch (5) connected to the speakerphone circuit (6) to automatically make a call through the speaker phone, characterized in that the automatic telephone.
