(EN) A support pin arrangement determination assisting apparatus includes: a display unit which displays a board image indicating an already mounted component on an already mounted surface; a position input unit through which an arrangement position of a support pin is input to the displayed image; a pin image display processing unit which causes the display unit to display a composite image which is formed by overlapping a pin arrangement image with an input arrangement position on a substrate image; and an interference judging unit, which judges whether any one of lower receiving pins with inputarrangement positions has interfered an installed part or not based on the three dimensional shape data of the electric part and the three dimensional shape data of the top of the upper end of the vertically arranged shaft of a substrate holding part. In the pin arrangement image, the flat image of the lower receiving pin comprises a top image and the image of the abut part, which supports the lower surface of the substrate, wherein the cross section of the substrate is smaller than that of the top.
(ZH) 本发明的下支撑销的配置确定辅助装置包括：显示装置，显示包含了表示已安装面中的已安装零件的形状和配置的基板图像的图像；位置输入单元，在显示的图像上输入下支撑销的配置位置；销图像显示处理单元，使显示装置显示将输入了配置位置的销配置图像重叠在基板图像上的合成图像；以及干扰判定单元，基于电子零件的三维形状数据和在基板保持部中竖立设置的轴部的上端设置的顶部的三维形状数据，判定输入了配置位置的下支撑销中的任何一个是否干扰了已安装零件，销配置图像中的下支撑销的平面图像包含顶部的图像、以及抵接到断面形状小于顶部即基板的下面进行下支撑的抵接部的图像。
