PURPOSE:To simplify a detector such as an input port by synthesizing the detecting outputs of a plurality of sensors and processing data. CONSTITUTION:A plurality of sensors (21, 22, 23,... 2N, a photosensor 210, a leaf switch 220), a signal synthesizing means (a signal synthesizing section 4) synthesizing the detecting outputs of each sensor, and an analog-digital conversion means (an analog-digital converter 8) converting a signal synthesized by the signal synthesizing means into a digital signal are provided. A data processing means (one-chip micro-processor unit 10) reading a digital value obtained by the analog-digital conversion means through a data bus and recognizing the detecting outputs of each sensor by the digital value is provided. |
