Surface potential detection apparatus |
摘要 |
A surface potential detection apparatus in which surface potential sensors are provided independently of one another. A switching circuit individually selects and outputs signals provided from the surface potential sensors with varied timing for individual surface potential sensors. A single signal processing circuit connected to the surface potential sensors via the switching circuit is shared by the surface potential sensors.
