Abstract

본 발명은 팩시밀리의 기록지 감지장치에 관한것으로, 종래 팩시밀리의 기록지 감지장치는 기록지잔량 감지센서와 기록지 유.무감지 센서를 각각 별도로 구성하므로 비용부담이 늘어나고, 회로구성이 콤팩트(Compact)하지 못한 단점이 있었다. 본 발명은 이러한 단점을 해결하기 위하여 1개의 센서만으로 기록지 잔량감지 및 기록지 유.무감지를 할 수 있게하여 비용부담을 줄이고, 콤팩트한 시스템을 구성할 수 있게 한 것이다.The present invention relates to a facsimile recording sheet detecting apparatus, and the conventional facsimile recording sheet detecting apparatus separately configures a recording sheet remaining amount sensor and a recording sheet presence / absence sensor, so that the cost burden increases and the circuit configuration is not compact. There was this. In order to solve this disadvantage, the present invention enables the recording paper remaining amount detection and the recording paper presence / absence detection with only one sensor to reduce the cost burden and to configure a compact system.
