Abstract
Official abstract text for this publication.
To provide a linear encoder including a scale unit and a slider that slides along the scale unit, wherein the slider includes a slider enclosure including a slider holding unit, a detection head holding unit mounted inside a scale enclosure of the scale unit, and a pillar extending between the outside and inside of the scale enclosure to connect these two holding units, and a part of the pillar closer to the detection head holding unit and a part of the detection head holding unit closer to the pillar are bored by a thickness larger than a thickness of the pillar.
First claim
Opening claim text (preview).
What is claimed is: 1 . A linear encoder having a scale unit and a slider that slides along the scale unit, wherein the slider has a slider enclosure including a slider holding unit, a detection head holding unit mounted inside a scale enclosure of the scale unit, and a pillar extending between outside and inside of the scale enclosure to connect these two holding units, and a part of the pillar closer to the detection head holding unit and a part of the detection head holding unit closer to the pillar are bored by a thickness larger than a thickness of the pillar. 2 . The linear encoder according to claim 1 , wherein boring of the pillar is applied to a part closer to the detection head holding unit than a position where a seal secured on the scale enclosure contacts the pillar when the pillar is assembled to the scale unit. 3 . The linear encoder according to claim 1 , wherein the slider enclosure is formed so as to include a through hole integrally molded between the part bored of the pillar and the slider holding unit. 4 . The linear encoder according to claim 1 , wherein the slider enclosure is given post processing for forming a through hole between the part bored of the pillar and the slider holding unit by means of milling machining. 5 . The linear encoder according to claim 2 , wherein the slider enclosure is formed so as to include a through hole integrally molded between the part bored of the pillar and the slider holding unit. 6 . The linear encoder according to claim 2 , wherein the slider enclosure is given post processing for forming a through hole between the part bored of the pillar and the slider holding unit by means of milling machining.
