A table game system is provided capable of identifying shuffled playing cards used at the time of the occurrence of a problem in a card shoe apparatus, thereby enabling an investigation of the cause thereof or the taking of countermeasures therefor. A card shoe apparatus of the table game system of the present invention includes a barcode reader that reads a barcode provided in a shuffled playing card set, thereby reading a shuffled card ID that uniquely identifies the shuffled playing card set. A sensor for detecting the opening/closing of the lid is provided under the lid to detect the opening/closing of the lid, thereby detecting replacement of the shuffled playing card set. A control unit further includes a function of storing security items in connection with a shuffled card ID.
