Claims

[Claims for Utility Model Registration] 1(a) A housing having a guide rail, a slider that moves along the guide rail in conjunction with an object to be measured within the housing, and a rotary encoder mounted on the slider. and a cable stretched inside the housing and in contact with a drive pulley of the rotary decoder, and converts relative linear displacement between the encoder and the cable into a rotational displacement to a predetermined rotational displacement. (b) a scale body that outputs a pulse signal for each amount of displacement; (b) a display unit that counts output pulses from the rotary encoder and digitally displays the amount of linear displacement of the object to be measured; A linear scale characterized by consisting of. 2 Utility Model Registration Scope of Claims The slider according to claim 1 comprises a first slider section that moves in conjunction with the object to be measured, and a second slider section that mounts the rotor encoder and moves along the guide rail, A linear scale characterized in that both slider parts are engaged in the direction of movement via bearings.
