琴曲摘要：A conveyer machine which has a forward conveyer part and a backward conveyer part continuous therewith, and which is simple in construction, small in size, and light in weight, and which can be applied to various fields. A reciprocal escalator rving as the conveyer machine compris a plurality of steps which are cloly dispod on looped guide rails dispod along a travel motion path including a forward ction and a backward ction which are continuous with each other through turning ctions. Adjacent steps are coupled to each other by a parallel link mechanism having coupling nodes each of which has opposite ends thereof lockably coupled to pin node points provided at columns of the steps and each of which is bendable around a pin dispod at the middle of the coupling node, so that the steps are enabled to smoothly travel around the travel motion part which includes ascent and descent ctions and curved ctions. The conveyor machine, which permits reciprocal transfer, which has freedom in tting the travel motion path, and which is simple, light and compact, is free from limitations in installation and execution, and hence can be applied to various fields.
