The present invention relates to an apparatus to count a plurality of semiconductor chips attached to a reel; a housing; an X-ray tube which is placed in the housing to irradiate X-ray; a detector which is placed in the housing at a position which corresponds to the X-ray tube; and a reel mounting unit which is placed between the X-ray tube and the detector in order for the X-ray to be irradiated and is mounted while the reel, which is attached to a plurality of semiconductor chips, is wound. The detector has a greater area than the size of the reel in order to obtain an X-ray image of the reel by one-time shooting. The reel mounting unit selectively sets a test position of the reel in accordance with the diameter of the reel, which is an object to be tested. The present invention is to provide a chip counting apparatus which can count a plurality of semiconductor chips attached to a reel in a short period of time by shooting the wound reel once and selectively set the test position in ...
