Abstract
A rectilinear motion apparatus includes two shafts arranged in parallel, a driving motor and a driving pulley coupled to one of the two shafts, an idler pulley coupled to the other of the two shafts, an endless toothed belt arranged between the driving pulley and idler pulley, and a slider disposed between the driving pulley and the idler pulley. The slider includes a first moving pulley and a second moving pulley of a diameter larger than a diameter of the first moving pulley. The first and second moving pulleys are integrally fixed to one another for rotation about the same axis so as to rotate simultaneously. A first pair of guide rollers are disposed on the slider adjacent the first moving pulley to guide a lower run of the toothed belt, and a second pair of guide rollers are disposed on the slider adjacent the second moving pulley to guide an upper run of the toothed belt. Regulating devices are provided for regulating shifting of the toothed belt in a disengaging direction of the toothed belt away from the first and second moving pulleys. Each regulating device is arranged on the slider and in a vicinity of an engaging part where the toothed belt is meshed with one of the first and second moving pulleys.
