摘要： A trolley is reciprocally moved along a guide. A work support, supported by the trolley, is vertically moved so that the lift mechanism can be made compact in size, or light weight and highly reliable in operation. Accordingly, the processing speed of the processing line is increased and the productivity is improved.
