摘要： A sealed linear encoder for determining the relative position of a first object and a second object. The sealed linear encoder includes a scale unit arranged in a hollow body that is mounted to a mounting structure associated with the first object and includes a slot which extends in a direction of measurement. A scanning unit for scanning the scale unit and a carrier connected to the second object, wherein the carrier extends through the slot. Sealing lips arranged at the hollow body and abutting the carrier so as to seal the carrier and a cover form-fitted to the hollow body for covering at least the slot.

摘要： A gage inspecting apparatus includes a jog dial 56A for controlling an amount of displacement of a measuring spindle 22 at a time when the position of the measuring spindle 22 is finely adjusted, and a shuttle ring 56B for controlling the driving direction and driving speed of the measuring spindle 22 at a time when the position of the measuring spindle 22 is roughly adjusted. The relationship between the amount of rotation of the jog dial 56A and the amount of displacement of the measuring spindle 22 can be set in correspondence with a scale interval of the gage.
