Title:
LINEAR ENCODER, GUIDE MECHANISM, AND METHOD FOR ATTACHING LINEAR ENCODER
Document Type and Number:
WIPO Patent Application WO/2023/085250
Kind Code:
A1
Abstract:
The present invention improves the workability of work for attaching a linear encoder while enhancing the precision of detecting the linear encoder. A base (12) is provided with a linear scale (26) extending in a first direction (D1), and a table (14) is provided with a reading head (34) for reading the gradations of the linear scale (26), the reading head (34) being provided facing the linear scale (26). A scale attachment surface (12d) for attaching the linear scale (26) to the base (12) is positioned on the same plane as a first rail attachment surface (12a) for attaching a guide rail (16L) to the base (12). A side-end surface (26s) of the linear scale (26) comes into contact with a side surface (16s) of the guide rail (16L).
