To operate a carrier through simple control.

A conveyor includes a carrier 12 which runs along a predetermined path while carrying the subject W to be conveyed; a plurality of drive wheels 41 positioned with predetermined pitches along the path of travel of the carrier for frictionally engaging an engaged part C of the carrier 12 to propel the carrier 12; a sensor LS provided on each drive wheel 41 for outputting an ON signal when the engaged part C of the carrier 12 is engaged with the drive wheel 41 and for outputting an OFF signal when the engaged part C of the carrier 12 is disengaged from the drive wheel 41; and a control means which outputs a drive signal for the drive wheel 41 when the sensor LS outputs the ON signal and which outputs a drive stop signal for the drive wheel 41 when the sensor LS outputs the OFF signal. The overall length L of the engaged part C of the carrier 12 is equal to the pitch P with which the drive wheels 41 are arranged.
