Support pin arrangement determination assisting apparatus

A support pin arrangement determination assisting apparatus which assists determination of an arrangement of a support pin that supports a lower surface opposing a component mounting surface of a board in a board holding unit of an electronic component mounting machine, the support pin arrangement determination assisting apparatus comprising:

• a display unit which displays an image including a board image, the board image indicating a shape and an arrangement of a component on the board;
• a position input unit through which an arrangement position of the support pin is input;
• a display processing unit which causes the display unit to display a figure to be superimposed on the board image, the figure corresponding to the support pin of which the arrangement position is input, wherein the figure comprises a first figure and a second figure surrounding the first figure;
• and
• a display switching unit switching a display on the display unit to display one of a first composite image based on a first board image and a second composite image based on a second board image,
• wherein the first board image is of the component mounting surface of the board and the second board image is of the lower surface opposing the component mounting surface of the board,
• wherein the first composite image comprises the shape and the arrangement of the component superimposed with the first board image, and
• wherein the second composite image comprises the shape and the arrangement of the component superimposed with the second board image.
