Title:
【発明の名称】直線値測定用電子光学センサー
Document Type and Number:
Japanese Patent JP2874813
Kind Code:
B2
Abstract:
The sensor has at least one sensor unit arranged opposite an incremental measurement scale (1) with reflecting graduation (2). The sensor unit comprises a photoemitter (3) and an adjacent photoreceiver (4), located in a printed circuit (6), with optical axes (xx') parallel to each other and perpendicular to the plane of the scale (1), and an optical group (9) with two focusing lenses (10, 12) and two deflection faces (11, 13) integrated by molding in a support of transparent synthetic material. In the optical group, one of the two lenses and one of the two deflection faces are aligned on each of the two said optical axes (x, x') in order to direct and deviate the light rays coming from the photoemitter (3) and to recover them on the photoreceiver (4) after their passage through a graduated sensing graticule (14).
