A card connector assembly includes: an electrical connector including an insulative housing, a plurality of terminals secured to the insulative housing, a shell covering the insulative housing to form a receiving cavity, and an ejector having a pivot; and a card tray removably received in the receiving cavity, the card tray having a front surface, wherein the card tray has a protrusion at the front surface, and the pivot has an engaging portion for ejecting the card tray, the engaging portion having a recess for receiving the protrusion and an ejecting end for riding onto the protrusion.

A card reader may include a main body part including a card conveyance path; a shutter member structured to move between a closed position and an open position; a first capacitance sensor provided in the main body part; and a control unit. The control unit may be structured to calculate a first output difference between an output of the first capacitance sensor in a first state and an output of the first capacitance sensor in a second state; calculate a second output difference between a maximum output of the first capacitance sensor in a period from the first state to the second state and the output of the first capacitance sensor in the second state; and determine that an object is installed when the first output difference is greater than a predetermined first threshold and the second output difference is less than a predetermined second threshold.

A card reader may include a main body part having a conveyance path; a first card detection mechanism disposed upstream of the main body part; a second card detection mechanism disposed in the main body part at a distance less than a length of the card from the first card detection mechanism; a shutter member disposed between the first and second card detection mechanisms; a shutter state detector; and a control unit. The control unit may be structured to close the shutter member when an object is detected by the second card detection mechanism after being detected by the first card detection mechanism, and then the inserted object is not detected by the second card detection mechanism while the inserted object is not detected by the first card detection mechanism; and detect that an object other than the card has been inserted when the shutter member close after the control.

A card reader for use with a card, the card reader may include a magnetic detector to detect magnetism from the card inserted into an insertion port; a main body part including a card conveyance path; and a card detection sensor structured to detect a tip end of the card. The magnetic detector and the card detection sensor may be disposed at a distance less than a length of the card in the insertion direction. The card reader may further include a control unit that monitors magnetism detected by the magnetic detector when the card detection sensor detects a tip end of an insert inserted into the insertion port, and detects that an object other than the card has been inserted when a movement distance of the insert in a period in which the magnetism is undetected by the magnetic detector is a predetermined value or more.

Various embodiments are generally directed to techniques to enable use of a transaction card of a user device to perform transactions. Embodiments may include method, techniques, and circuitry to cause a transaction card to extend from a user device to be used to perform the transactions. Further, the transaction card may retract into the housing the user device when not in use.

A mechanism for releasing a SIM card locked into an electronic device by a spring-loaded mechanical restraint (4, 5) includes a SIM card holder comprising a rectangular frame (1), a SMA wire actuator (10) mounted on said frame (1) so as to deform it upon activation in order to release said mechanical restraint (4, 5), and springs (8) for the ejection of the SIM card holder upon release of the mechanical restraint.

An embodiment of the present invention provides a card issuing device, which includes a card storing mechanism, a transport mechanism, and a base. The transport mechanism is arranged in the base. The card storing mechanism is arranged above the transport mechanism. The card storing mechanism comprises a pressing block and a buckle. The transport mechanism comprises a guide rail and a card hook. The transport mechanism transports a card by cooperating of the guide rail and the card hook. The card storing mechanism fixes the card via the pressing block and the buckle. The base is configured to fix the card storing mechanism and the transport mechanism. According to the present invention, a card issuing box and a card receiving box are integrated into one body to reduce structural complexity, reduce costs, and improve space utilization rate.

A card reader use in a higher-level device may include a card transfer path; a card insertion detecting mechanism; a transfer roller; a turn detecting mechanism structured to detect a turn of the transfer roller; a card detecting mechanism; and a control unit. The control unit structured such that, if the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism, the control unit of the card reader sends a control unit of the higher-level device an alarm signal for notifying that a skimming device has been inserted through the insertion slot.

A card reader may include a card holder and a card ejection mechanism for moving the card holder. The card ejection mechanism includes a connection arm connecting the main body frame with the card holder, a solenoid for bending the connection arm, and an arm urging member urging the connection arm. When the solenoid is switched to a non-energized state, the solenoid pushes the connection arm and the connection arm is changed from an extended posture to a bent posture. The connection arm in the extended posture is restricted from bending to an opposite side to the bent posture side and, in a state that the connection arm is in the extended posture, the arm urging member applies an urging force to the connection arm so that the connection arm is bent to an opposite side to the side of the bent posture.
