摘要:
A scale comprising a regular arrangement of optically or magnetically different response characteristics such as light reflection and light diffusion portions or light reflection and absorption portions is attached to a moving object either directly or by way of an intermediate member. The scale can be attached to a motor or the like even after assembling with associated mechanical components, thereby enabling easy measurement of the mode of operation of the motor or similar movable objects. The light beam from the light emitting device is directed to the label media and the reflected light beam is received by a light receiving device to identify the individual object or product based on the label.
