１項記載のセンサー装置。[Claims for Utility Model Registration] (1) An analog sensor that outputs an analog voltage signal of a predetermined width depending on the state of the object to be measured, and a first input that can switch between a first input state and a second input state and output the signal. The output of the analog sensor is input as a state, and a voltage signal having a voltage value different from the output voltage width of the analog sensor is input as a second input state.
A sensor device comprising: input switching means; and detection means to which the output voltage of the two-input switching means is input and detects a change in the state of the input based on the input voltage. (2) The two-input switching means is a thermal transfer mode/thermal mode switching switch of a recording device for both thermal transfer and thermal recording, and the analog sensor is a photo sensor that detects the presence or absence of an ink ribbon in the recording device. A sensor device according to claim 1 of the utility model registration claim.
