Abstract
To provide a substrate transport device and a transport teaching system which can automatically perform a teaching processing in order to reduce the burden of an operator and to eliminate a positional shift accurately and efficiently in a short time. Optical connectors 251, 252, 253 and 254 of a jig 200 and optical connectors 256, 257, 258 and 259 fixedly provided on a substrate transport device are opposed to each other and optical axes are coincident with each other. A lens having a high condensation ratio is provided in each optical connector. A light signal is output from optical sensor heads 231 and 241 through an optical fiber F2, each optical connector and an optical fiber F1, and a light signal input to optical sensor heads 232 and 242 is guided into the substrate transport device. Then, an arm 31b is automatically moved in a three-axis direction. Thus, an edge position of a detected portion 122 is detected to acquire positional information so that teaching information is obtained.
