Abstract

본 발명은 전화기의 후크스위치 자동전화장치에 관한 것으로, 종래에 있어서 전화기의 수화기를 잘못 놓았을 때 벨이 울리지 않는 것을 해결하기 위한 것이다. 즉, 전화기의 기계적인 후크스위치의 역할을 릴레이와 릴레이구동부를 이용한 전기적인 장치를 추가하고, 수화기의 손잡이에 스위치를 장치함으로써, 사용자의 실수로 인하여 전화기가 제대로 동작하지 않는 것을 방지하게 되고, 후크 스위치가 오프되어 있는 것이 통화중인가 아닌가를 판단할 수 있는 잇점이 있게된다.The present invention relates to a hook-switch automatic telephone apparatus of a telephone, and to solve a problem in which a bell does not ring when the telephone receiver of a telephone is misplaced in the related art. In other words, by adding an electric device using a relay and a relay driver as a mechanical hook switch of the telephone, and by installing a switch on the handle of the handset, the telephone is prevented from operating properly due to a user's mistake. There is an advantage to determining whether the switch is off or not.
