摘要：
A transport device which accomplishes transport well by means of a linear motor mechanism well even if a chain is elongated. The transport uses the chain in a first transport section, and the linear motor mechanism in a second transport section. A coupling pin of the chain is disengaged from a chain coupling portion of a table when the table is transferred to the second transport section and the coupling pin is brought into engagement with the chain coupling portion again when the table is transferred to the first transport section. A driving speed at which a pair of rotary members are driven by the chain driving mechanism is corrected in accordance with the elongated condition of the chain, based on a count of driving pulses in the chain driving mechanism during the passage of the coupling pin through the second transport section.
