Abstract: A substrate conveyance mechanism that includes conveyance units and a working area length change part to easily change the types of substrates to allow substrates of different lengths to be selected to mount electronic components onto the substrate. The conveyance units include a working area for substrates having different length that are conveyed from a stand-by area, an area length of the working area that is variable in accordance with the length of the substrate, and a stand-by unit corresponding to a stand-by area for the substrate to be carried in to the working area. The working area length change part changes an interval between a commonly used first pulley and one of a plurality of second pulleys selectively used in accordance with the area length of the working area by changing a belt winding path of a conveyance belt wound on the pulleys in the working unit.
