A lower supporting pin module 22 is given a shape having a contact surface 26 a . On the occasion of position recognition for determining a position of a pin on the lower supporting pin module 22 , an image of the lower supporting pin module 22 is captured, and the image is subjected to recognition processing, to thus detect an outer shape of an upper shaft 24 B. Even when an extraneous matter on a downside surface of a substrate adheres to the contact surface 26 a , the position of the lower supporting pin module 22 can be stably recognized with superior recognition precision.

The objective of the present invention is to provide an electronic component mounting device and an image reading method used by the electronic component mounting device, such that the time required for reading images can be reduced by using image reading units having a simplified structure so as to eliminate restrictions which are caused by the array direction of line sensors and imposed upon the operations of mounting heads. The image reading units (6A, 6B) for reading images of electronic components held by the mounting heads (14A, 14B) are each configured to have a line sensor that is tilted at a placement angle with respect to a first direction; which mounting head (14A, 14B) should be assigned for a first-direction scanning operation or a second-direction scanning operation is selected on the basis of scanning operation selection conditions that have been set in advance; and in an image acquisition step for obtaining images from the image reading units (6A, 6B), image conversion processing is executed such that a two-dimensional image is generated by juxtaposing one-dimensional images which are obtained by transforming one-dimensional images output sequentially from the line sensors to the degree of the placement angle.
