A card-type storage device and a slot device, which are capable of preventing lowering of the reliability due to repeated insertion and removal of the storage device. A card medium includes card thermal contacts each having a contact surface which intersects with a thickness direction of the card medium. A first card upper guide surface restricts the position of the card medium in the thickness direction to a first position. An escape portion restricts the position of the card medium in the thickness direction to a different position from the first position. A second card upper guide surface links the first card upper guide surface and the escape portion.

Disclosed are a two-dimensional code card grabbing and storage device and method. The two-dimensional code card grabbing and storage device includes a horizontal base plate. First side plates and second side plates are sequentially disposed on the front side and the rear side of the horizontal base plate separately in the horizontal direction and perpendicularly fixed to the upper surface of the horizontal base plate. First baffles extending inwards are oppositely and perpendicularly disposed on the outer sides of the two first side plates, and second baffles extending inwards are oppositely and perpendicularly disposed on the inner sides of the two second side plates. A first guide plate used for storing tested two-dimensional code cards is obliquely disposed upward between the two first side plates, and a second guide plate used for storing to-be-tested two-dimensional code cards is obliquely disposed upward between the two second side plates. The two-dimensional code card grabbing and storage device further comprises a grabbing plate with one side attached with a nano micro-suction material and the other side fixedly connected with a mechanical claw controlled by a mechanical claw driving mechanism. The present invention has the beneficial effect of sequentially grabbing, discharging, sorting and storing two-dimensional code cards.
