A connector electrically connecting a module substrate and a main substrate includes: a housing mounted on the main substrate; contacts held on the housing and including contact parts and connection parts connected to the main substrate; a frame including side board parts sandwiching a flat board part and the main substrate, the side board parts forming one of a cam groove and a projection; and a slider having opposite side portions forming the other of the cam groove and the projection, forming an insertion space between the slider and the housing upon the projection's insertion into the cam groove and the slider's attachment to the frame, pressing the module substrate against the contact parts upon the slider sliding in the module substrate's insertion direction, sandwiching main substrate, the housing and the module substrate between the slider and the flat board part.

A card reader includes a card lock mechanism preventing pulling-out of a card jammed in a card conveyance passage, and an operation part for manually releasing lock of the card caused by the card lock mechanism. The card lock mechanism includes a motor, and a lock member which is provided with a blocking pawl for preventing pulling-out of the card and is moved between a contact position where the blocking pawl contacts the card and a retreated position where the blocking pawl is retreated from the card conveyance passage. The operation part includes a rotation member in a tube shape having an inner circumference wall surrounding an output shaft of the motor, and an engaging member provided on the inner circumference wall and extended along a circumferential direction of the output shaft and engageable with an outer peripheral face of the output shaft. The engaging member is elastically deformable.

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 card reader may include a card passage where a card passed; a contact block including IC contact springs; a card insertion detection mechanism; a lock member; a lock member drive mechanism that moves the lock member between a pulling-out prevention position and a pulling-out feasible position; a lock member detection mechanism; and a control unit structured to control the card reader. The lock member may include a pulling-out prevention part. A distance between the front end of the IC card and the pulling-out prevention part may be shorter than a length of the IC card in the moving direction of the IC card. The control unit detects that insertion of the IC card has been completed the IC card has been inserted to the contact position and the lock member is located at the pulling-out prevention position.

A card processing device may include a card reader and a printer. The printer may include an ink ribbon cartridge; a thermal head; and a cover member. The ink ribbon cartridge may include a supply roll and a take-up roll. The thermal head may heat the ink ribbon and transfer ink to the card. The card reader may be on a front side of the thermal head, and a part of the card reader may be on a lower side of the supply roll or the take-up roll. The cover member may pivot between a closed position and open position. A conveyance path may be provided inside the card reader and the printer. A part of the conveyance path inside the card reader may be a first conveyance path. The card reader may include an upper frame. The upper frame may pivot between a closed position and open position.

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.

An electronic payment terminal has a casing which is formed by assembling an upper half-shell and a lower half-shell. The lower half-shell includes a magnetic-card-reading single-piece element that has a groove for the movement of a magnetic card so as to enable reading of a magnetic stripe of the magnetic card. The magnetic-card reading single-piece element has a metal sliding blade positioned at the bottom of the groove for movement of the magnetic card.

Provided is a system for identification of an item, wherein the system includes a conveyor belt, a positioning device and a reader operable to receive at least one reading, wherein the positioning-device is configured to retrieve a first position of the item) at a first time instant before the first antenna and a second position of the item at a second time instant after the first antenna, the first and second time instants defining a time window, wherein the reader is configured to extract from each reading retrieved by the first antenna a measurement of the phase of the signal transmitted by the tag and perform a data processing of the phase measurements, whereby the identification of the item is accomplished.
