According to various embodiments, an electronic device may include: a housing including an opening connected to an internal space of the electronic device; a tray socket connected to outside the electronic device through the opening in the internal space and including a tray reception space; a tray configured to be inserted into the tray reception space, wherein the tray includes a tray body including at least one space configured to receive at least one external component; and a tray cover including a pin insertion hole configured to guide a tray ejecting pin to the opening; an eject bar movably disposed in a tray mounting direction or ejecting direction in the tray reception space and facing the pin insertion hole; and a rotation lever configured to press the tray in the ejection direction based on pressing of the eject bar in the tray reception space, wherein the eject bar is disposed at a position at least partially overlapping the tray body when viewed from above the tray socket.

Some embodiments include a smart card reader system that includes a card reader cavity that is impervious to liquid. The card reader cavity includes a secure card reader (SCR) holder bonded to a printed circuit board (PCB), to provide a liquid barrier between the SCR holder and the PCB. The PCB includes an SCR spring contact connector. The card reader cavity can receive a smart card including an integrated circuit (IC), where the IC is coupled to the SCR spring contact connector. A processor coupled to the SCR spring contact connector, can receive an input regarding a transaction using data of the smart card, and execute the transaction. In some embodiments a roller system seals the card reader cavity when the smart card reader system is not in use.

To enable compatibility with smaller, thinner, and multi-polarized cards, to enable miniaturization, flattening, and multi-polarization and increase reliability. Therefore, provided are: a tray housing including a recessed part capable of housing a card, a bottom wall part that defines the bottom surface of the recessed part, and a tray terminal housing recess formed on the bottom wall part; and tray terminals that are arranged on the bottom wall part which includes a main body at least part of which is retained by the bottom wall part, a first contact part and a second contact part that are connected to both ends of the main body part respectively, of which the first contact part is contactable to the connector terminal and the second contact part is contactable to the electrode pad; where the first contact part is fixed and exposed on the opposite side to the bottom surface of the recessed part of the bottom wall part, and the second contact part is housed in an elastically deformable manner in the tray terminal housing recess in a state where at least the point of contact thereof protrudes from the bottom surface of the recessed part.

An electronic device is provided that includes a housing having a first side with an insertion hole. The electronic device also includes a first tray configured to accommodate at least a subscriber identity module (SIM). The first tray is inserted into the housing through the insertion hole and is removably accommodated within the housing. The electronic device further includes a second tray configured to accommodate at least a memory card. The second tray is inserted into the housing through the insertion hole and is removably accommodated within the housing. In a state of being accommodated within the housing, the first tray and the second tray are at least partially disposed on the same plane, and at least a portion of the second tray is exposed to an outer surface of the housing while closing the insertion hole.
