Electronic part packaging body side face photographing device

The invention provides an electronic part packaging body side face photographing device which is simple in structure and which can check electronic part packaging bodies such as a QFN packaging body at a high speed. Two reflecting prisms are disposed at the periphery (four edges) of the oblique lower part of the outer side of a side face of the QFN packaging body of a photographing position P existing in a horizontal-conveying conveying path, and a CCD camera is configured below the two reflecting prisms through a telecentric lens. When the QFN packaging body comes at the photographing position P, light of the side face of the QFN packaging body is reflected for two times on the two reflecting prisms and goes downwards to photograph through the CCD camera. The QFN packaging body can stop at the photographing position of the QFN packaging body and can also pass through the photographing position without stop. For a condition that the QFN packaging body stops at the photographing position and then passes through the photographing position, photographing time of a photographing device is better to be set as short time which enables a photographing image to not generate a shake. Because the two reflecting prisms are configured at a position lower than the conveyed QFN packaging body, the QFN packaging body can perform photographing in a transfer path and does not need to move in the vertical direction.
