Claims

[Scope of utility model registration request]

By reading the signals generated when the main scale attached to the movable part (or fixed part) of a machine tool, etc. and the reading head attached to the fixed part (or movable part) move relative to each other, the movable part can be detected. In a linear scale measuring device for measuring the amount of movement, a pivot bearing attached to the lower end surface of the reading head and a stand bolt installed in a fixed part of the machine tool are movable up and down and the angle can be changed. a connecting arm that can be fixed to the connecting arm; a pivot bearing mounted on the upper part of the connecting arm so as to face the pivot bearing mounted on the lower side end surface of the reading head; and a pivot sandwiched between the two pivot bearings. A linear linear system comprising a shaft, a cap nut that covers the pivot shaft and engages with each of the pivot bearings, and an elastic member that is housed in the cap nut and has a pressing force stronger than the sliding resistance when the reading head moves from side to side. Mounting device for scale measuring device.
