ABSTRACT:
A signal outputting device of optical ruler is disclosed. It includes a first guide seat formed with an internal axial chamber for receiving a reflecting plate therein, a second guide seat including a slide block axially movable within the chamber and a resilient lever having a fixed end disposed on the slide block, and a sensor disposed on outer side of the slide block. An inner side of the sensor abuts against a free end of the resilient lever. The slide block is disposed with two first stopper sections spaced from each other by a certain distance. The sensor is positioned between the first stopper sections. A section of the sensor, which contacts with the free end of the resilient lever, is formed with a guide channel axially parallel to the moving direction of the slide block. In the case of change of the distance between the first and second guide seats, the accuracy of the optical ruler for measuring length will not be affected.
