PROBLEM TO BE SOLVED: To reduce the capacity of a drive source (a motor or the like), to mitigate interference with a press machine, to realize the simple control, and to simplify a constitution of a driven mechanism. SOLUTION: An elevating/lowering feed mechanism 12 comprises an elevating/lowering lift frame 16, a carrier 18 to be horizontally moved in the feeding direction with respect to the lift frame 16, a sub carrier 20 to be horizontally moved straight in the feeding direction with respect to the carrier 18, and a driven mechanism 30 for moving the sub carrier 20 interlockingly with the movement of the carrier 18. The driven mechanism 30 has a pair of rotating bodies 31 to be rotatably supported by the carrier 18 with a spacing longitudinally in the feeding direction, and an endless rope body 3 stretched around the pair of rotating bodies 31. The endless rope body 33 is connected and fixed to the lift frame 16 on a part thereof. The sub carrier is connected at the position once via the rotating bodies with the connection position to the lift frame being a base point in the endless rope body 33. COPYRIGHT: (C)2009,JPO&INPIT
