Claim Text:
1. A linear conveyor, comprising: a linear motor stator including a plurality of electromagnets arranged along a predetermined conveyor path, and operable to individually undergo electric current supply control with respect to each of predetermined zones; a plurality of conveyor carriages each provided with a linear motor rotor and with a unique information storing device configured to store predetermined unique information, the linear motor rotor being constituted of a permanent magnet and constituting a linear motor in cooperation with the linear motor stator, the conveyor carriages being disposed to be movable along the conveyor path; a plurality of motor control devices provided in the respective corresponding zones of the linear motor stator, and configured to individually perform electric current supply control for the electromagnets with respect to each of the zones; and a reading device configured to read the unique information stored in the unique information storing device, the unique information storing device being configured to store, as the unique information, position correction data for use in correcting a movement error unique to the conveyor carriage, and each of the motor control devices being configured to determine, as control data, either the position correction data read by the reading device or process data processed with use of the position correction data for performing electric current supply control for the electromagnets with use of the control data so as to stop the conveyor carriage at a target stop position.
