To provide a card handling device which has a card rotation mechanism having a plurality of card conveyance passages to deliver a card between the card conveyance passages and capable of being miniaturized by reducing size of the card rotation mechanism.

This card handling device is provided with a sensor for detecting a card position in the card rotation mechanism to shorten length of the card conveyance passage in the card rotation mechanism by compensating deviation of card position caused during rotation of card in the card rotation mechanism and stabilizing the card position after rotation, reduce size of the card rotation mechanism, and miniaturize the card handling device.
