Position detector and linear conveyance system

A linear conveyance system comprising:

• a conveyance path including a stator;
• a mover to move along the conveyance path, the mover forming a linear servomotor with the stator;
• a position detection-specific magnet installed on the mover;
• a position detection sensor installed on the conveyance path to detect a magnetic field generated by the position detection-specific magnet;
• a plurality of magnetic shielding members arranged and installed with a gap in a first direction that is a direction of movement of the mover along the conveyance path, the plurality of magnetic shielding members being capable of providing a shield against magnetic flux heading from a moving magnet of the mover and coils of the stator to the position detection sensor;
• and
• a gap-specific magnetic shielding member closing the gap between adjacent ones of the magnetic shielding members, the gap-specific magnetic shielding member being capable of providing a shield against the magnetic flux.
