1. A position detecting system comprising:
- a moving machine capable of moving along a predetermined path;
plural storage media configured to store position information and arranged in parallel along the path;
and a reading unit provided on the moving machine side and configured to read the position information of the storage media arranged in a reading range corresponding to the reading unit, whereinarray information corresponding to positions of the plural storage media is stored in the storage media as the position information,the system includes, as the reading unit, a first reading unit and a second reading unit having a reading range wider than that of the first reading unit,the system changes the reading range according to moving speed of the moving machine to read the position information of the storage media with the first reading unit when the moving speed of the moving machine is in a low-speed state and reads the position information of the storage media with the second reading unit when the moving speed of the moving machine is in a high-speed state, andthe system excludes, in the reading by the second reading unit, a part of the position information obtained from the plural storage media arranged in the reading range based on an order set in advance.
