A card storing case includes a left plate and a right plate arranged opposite to one another. An inner side of the left plate and an inner side of the right plate are respectively provided with a plurality of guide grooves. The card storing case further includes a card bracket slidably arranged in the guide groove. When a card is transferred into the card bracket, the card bracket slides along the guide groove, such that the card is moved and stored in the guide groove. A card bracket and a guide groove are arranged in the card storing case, such that a card is moved and stored in the guide groove via the card bracket, which not only shortens a transfer path of the card in a process of storing or withdrawing the card, but also reduces operation time in storing or withdrawing the card.
