US Patent:

20030094568, May 22, 2003

Filed:

Nov 16, 2001

Appl. No.:

09/991441

Inventors:

John Meschko - Sandpoint ID, US

International Classification:

G01D005/34

US Classification:

250/231130

Abstract:

An encoder detects angular movement between a shaft and support about a rotational axis. A base mounts a signal emitter and sensor. A fitting is mountable to the shaft, coaxial with the rotational axis. A signal interrupting disk on the fitting is positioned in spaced relation to the emitter and sensor. An alignment bracket may be mounted to the base for relative axial movement. A yieldable member axially biases the base and alignment bracket to a pre-mounting relationship. A fastener secures at least one of the base or alignment bracket to the support, deflecting the yieldable member and positioning the emitter sensor, in a prescribed operative position on the support. The yieldable member will return the base and alignment bracket to the pre-mounting relationship when the encoder is removed from the support.

Abstract:

An optical encoder is disclosed, the optical encoder generally including an encoder framework, a light source for emitting light, said light source mounted to the encoder framework, a light detector attached to the encoder framework and disposed to receive light emitted from the light source, a light interruption screen with opaque regions and transparent regions, the opaque regions and transparent regions being movably positioned between the light source and the light detector such that movement of the opaque regions interrupts the light emitted from the light source to the light detector, and further wherein the light source is mounted to the encoder framework transverse such that the light is emitted at an angle from the axis of the rotating member.
