[0003] A search of the Chinese patent publication number CN 116212357 A discloses an intelligent automatic card dealing machine, which addresses the problem of most current card dealing machines being difficult to remove from a card compartment when only a small number of playing cards are present due to their light weight. This patent addresses the problem of the intelligent automatic card dealing machine being difficult to remove from a card compartment when only a small number of playing cards are present. This patent provides a first card-feeding roller assembly corresponding to the front end of the playing cards and a second card-feeding roller assembly corresponding to the rear end of the playing cards. This design increases the friction between the first and second card-feeding roller assemblies and the playing cards during operation, allowing the playing cards to be removed from the card outlet without requiring a card-pressing lever. This increases the usable space, making it easier for users to access the playing cards and facilitates assembly and disassembly. However, the aforementioned device, driven by a pulley, has low precision, making it prone to multiple cards being released and stacked at the card inlet, causing card jams.
