PROBLEM TO BE SOLVED: To provide a PTP sheet tablet detection device that can simply deal with a kind change of the PTP sheet tablet, does not provide a complex structure and can simply perform a maintenance. SOLUTION: A light is irradiated to raised-shape pocket parts 1A to 1N from a diagonal direction of a PTP sheet 1 in which tablets 1a to 1n are packed and the device is equipped with a projecting device 3, a CCD camera 4 for picking up an image of the PTP sheet 1 on which a light is projected by the projecting device 3, an A/D converter 5 and a limiter 6 for detecting a contract of an image picked up by the CCD camera 4 and a discrimination part 8 for judging if there are the tablets 1a to 1n packed in the PTP sheet 1 by judging if there is any shadow based on the detection signal of the limiter 6. |
