Title: Detecting device for physical body
Inventor: TANI MASATO
IPC: G01V9/00
Filed: 1986-03-17
Abstract: PURPOSE:To reduce the size and cost of a device by utilizing an electric reacting means which varies in electronic characteristics according to mechanical variation based upon whether a physical body to be detected is present or not and detecting whether the physical body to be detected is present or not from its electric variation. CONSTITUTION:A mechanical detecting means 113 contacts the physical body 111 to be detected mechanically to cause mechanical variation based upon whether the physical body 111 to be detected is present or not. Then, the electric reacting means 115 varies in electric characteristics according to the mechanical variation. Then, an electric characteristic detecting means 117 detects variation in the electric characteristics of the electric reacting means 115 to judge whether the physical body 111 to be detected is present or not. Therefore, the electric characteristics of the electric reacting means 115 are varied by the mechanical detecting means 113, so the constitution of the device is simplified according to the size reduction of the electric reacting means 115.
