In a card reader, an interfering magnetic field generation mechanism 11 includes a core part 14a, a core part 14b, and a core part 15a, each of which is formed of soft magnetic material in a straight line, a coil 16 that is wound around the core part 14a, a coil 17 that is connected to the coil 16 in series and is wound around the core part 14b, a coil 18 that is wound around the core part 15a, a first drive circuit that supplies alternating current to the coils 16 and 17, and a second drive circuit that supplies alternating current to the coil 18. The core part 15a is disposed between the core part 14a and the core part 14b. The core part 15a is formed independently of the core parts 14a and 14b, and is separated from the core parts 14a and 14b.

A gate assembly can include a housing, a main body, at least one member, and an activation rib. The housing can define at least a portion of a card path of a payment interface. The main body can be coupled to the housing and can be movable between a closed position and an open position. The at least one member can extend from the main body such that, when the main body is in the closed position, the at least one member extends into the card path and can be oriented to inhibit an item from traveling through the card path. The activation rib can extend from the main body and can be located such that, when the main body is in the closed position, the activation rib extends into the card path. Related apparatus, systems, techniques, and articles are also described.

A card reader may include card insertion port; a plurality of types of pulling-out detection mechanisms; and a pulling-out prevention mechanism. The pulling-out prevention mechanism may include a lock member having a prevention part configured to contact with the card and prevent pulling-out of the card; and a moving mechanism structured to move the lock member between a contact position and a retreated position. The plurality of types of the pulling-out detection mechanisms may the abnormal pulling-out of the card by methods different from each other. The lock member is moved to the contact position from the retreated position to prevent pulling-out of the card when the abnormal pulling-out of the card from the card insertion port is detected by the plurality of types of the pulling-out detection mechanisms.

A card reader includes a front wall where a card insertion slot opens, a conveyance path extending from the insertion slot toward a back side, a conveyance mechanism configured to convey a card inserted into the insertion slot along the conveyance path, a magnetic head configured to read information from the card conveyed by the conveyance mechanism, and a recess recessed from the front wall toward the back side and configured to expose inside both sides of a rear end of the card conveyed to the back side along the conveyance path.

A card processing device may include a print unit and a card inverting unit that inverts front/rear of the card. The print unit may include a thermal head and a card conveyance mechanism. The card inverting unit may include a card holding part, a card drawing and feeding mechanism, and a rotating mechanism that rotates the card holding part. A conveyance path may be provided inside the card holding part. The conveyance path may be linear. The card drawing and feeding mechanism may include two drive rollers, and two pad rollers. A distance between a center of the drive roller and a center of the thermal head may be shorter than a length of the card. The thermal head may print on the card while the card conveyance mechanism conveys the card. The rotating mechanism may rotate the card holding part such that the conveyance path is inclined.

A card socket for mounting a SIM card and an SD card for a mobile communication terminal includes a housing and a shell. The housing includes a first terminal portion having a first terminal disposed therein, a second terminal portion having a second terminal and a third terminal disposed therein, and a switch portion. The shell includes an upper wall and a sidewall. The shell includes a sensing portion extended from the upper wall to detect insertion of a card tray into the card socket. The sensing portion has a shape which is extended downward from the upper wall in the height direction and then is extended upward in the height direction. The switch portion includes a stopper which is configured to come into contact with an upper surface of the sensing portion and to prevent the sensing portion from being lifted up in the height direction.
