Patent ID: 8321175

Claim:
A device for measuring resilience and displacement, comprising: a shaft, mounted on a platform with linkage such that enable the shaft moving in a reciprocating manner; a displacement detection module, configured with a light sensor and a reflective panel such that one component selected from the light sensor and the reflective panel is mounted on the shaft while arranging another component at a position corresponding to the selected component such that the two components work cooperatively to measure the displacement of the shaft; and a force detection module, disposed at an end of the shaft that is opposite to the displacement detection module and configured with a detection film having a probe and a strain gauge being respectively arranged on two opposite sides thereof for enabling the strain gauge to measure a resilience according to deformation of the detection film as soon as the probe is pressing on a tested press-key; wherein, when the shaft is driven to displace for enabling the probe to press upon the tested press-key, the displacement detection module and the force detection module are enabled to measure the displacement and resilience simultaneously.
