を目的としている。In the above-mentioned complicated conventional measurement input device, each flying capacitor relay operates in synchronization with each scanning signal sent out with a time difference, so the timing of reading multiple measurement input information is different, and the timing of reading multiple measurement input information is instantaneously simultaneous. There are problems with the accuracy of measurement data because multiple pieces of measurement input information cannot be collected at the same time as the process progresses, and there are also disadvantages such as the need to provide a flying capacitor relay for each AIC. This was done in order to eliminate the drawbacks of the conventional one, by placing the flying capacitor relay inside and putting the nine measurement input circuit in front of the AIC.The flying capacitor relay can be removed from the Arc, and multiple measurements can be performed. The purpose of the present invention is to provide a measurement input device that can simultaneously read input information at the same timing.
