PURPOSE: To transfer a plate-like body calmly and safely by offsetting a fall difference between both ends of an arc motion, moving a forward end of a link mechanism horizontally, and moving the forward end of the link mechanism horizontally at a one-stage higher position only in its first half way

CONSTITUTION: A U-shaped cam 10 and a pinion 8 are rotated by a drive pulley 5 directly connected to a motor 11 through a shaft 7 of a follower pulley 6. The pinion 8 actuates a link mechanism by a gear 9 and a link 12b, and a slide unit 3 supporting these is slidably engaged with a rail 2 to compose a first support means 1a. The slide unit 4 is slidably engaged with the rail 2 similarly to support the first support means 1a through a roller 15, and a slide unit 4 is supported through a cam 16 which is in shaft-contact with a motor 17 to compose a second support means 1b.
