Zusammenfassung:To provide a conveyor capable of fixing a substrate to a mask without generating a chip in a substrate, and without generating dust; and to provide a vacuum device having the same.SOLUTION: In the state where a magnetic field formed between the tip of a magnetic core 36 and the tip of a yoke part 35 by a permanent magnet part 17 of an adsorption part 321 provided on a frame body 31 for a mask is weakened by a magnetic field induced by sending a release current in an electromagnet part 14, the frame body 31 for the mask and a frame body 41 for a substrate are brought close to each other, to thereby achieve positioning between the mask 15 and the substrate 16. After positioning, the release current is stopped, and the frame body 41 for the substrate is magnetically adsorbed to the frame body 31 for the mask by the magnetic field of the electromagnet part 14, and both are moved together.SELECTED DRAWING: Figure 11 【課題】基板に欠けが生じず、ダストを発生させずに基板とマスクとを固定することが可能な運搬装置、及びそれを有する真空装置を提供する。【解決手段】マスク用枠体31に設けられた吸着部321の永久磁石部17が磁芯36の先端とヨーク部35の先端との間に形成する磁界を、電磁石部14に解除電流を流して誘起された磁界によって弱めた状態で、マスク用枠体31と基板用枠体41とを近接させ、マスク15と基板16との位置合わせを行う。位置合わせ後解除電流を停止し、電磁石部14の磁界で基板用枠体41をマスク用枠体31に磁気吸着させ、一緒に移動する。【選択図】図11
