    摘要: A work or component mounting apparatus according to the present invention comprises a rotating drum arranged above a workbench and divided into upper and lower drums, a head unit detachably mounted to the lower drum of the rotating drum, a circular work head (or, in other words, a component head) attached to the head unit, a suction nozzle protruding from the outer peripheral surface of the work head toward the workbench, and a controller housed in the upper drum of the rotating drum for controlling the turning motion of the work head and the supply of suction pressure to the suction nozzle. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench.

    摘要: An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave 1 and a driving mechanism 2 is positioned between an inner wall 3a of the elevator path 3 and a space occupied by an elevator car 4 rising and falling in the elevator path 3. One end of a suspension rope 7 is fixed to the elevator car 4 in a position below a ceiling 4c of the elevator car 4. With the arrangement, the car 4 can move close to the ceiling 4c of the elevator car 4 effectively. Further, it is possible to reduce respective heights of the elevator path 3 and a building equipped with the elevator apparatus.
