A card reader may include a conveyance passage; an optical sensor; a first circuit board; a second circuit board; a first cover member; a second cover member; a first frame; and a second frame comprising a conveyance face on a second direction side of the card conveyance passage. The first frame may include a first transmission hole, and the first frame may be attached with one of the first circuit board and the second circuit board. The second frame may include a second transmission hole, and the second frame may be attached with the other of the first circuit board and the second circuit board. The first cover member may be fixed to the first circuit board so as to cover the entire light emitting element; and the second cover member may be fixed to the second circuit board so as to cover the entire light receiving element.

A stem ejectable component assembly for electronic devices does not use a pin or needle to eject the tray holder. The assembly includes a receiving housing coupled to a SIM/MMC tray, a front plate, and a stem. The front plate incorporates slider pins that slide out to engage with recesses in the support frame of the electronic device to lock the assembly. The slider pins have inner ends that abut the stem and hold the stem in a pushed-in position. The slider pins also incorporate profiled protrusions that engage with ball pins fixed to the receiving housing. When the front plate is pushed inward, the profiled protrusions cause the slider pins to move outwards and release the stem to project out of the front plate. Pulling the stem causes the slider pins to slide in and disengage from the recesses in the support frame to enable withdrawal of the assembly.

A player tracking reader that accepts traditional magnetic strip cards and contactless chip cards, that can also accept smart cell phones in lieu of a player tracking card is disclosed. The reader can positively verify that a player with a cell phone is physically present at a particular slot machine and has further means to verify the continued presence of the player. The reader communicates with existing slot machines by mimicking the communication protocol of a legacy card read while actually interfacing to a smart cell phone possessing a player ID number.

A card processing device may include a moving part having a support member and a presser member, the moving part being structured to move in the thickness direction of the card; a holding member; an abutting member; a first urging member urging the abutting member in the ejecting direction; a second urging member urging the moving part; and a drive source to move the moving part. In inserting the card, the holding member may slide from a hold position to a retreated position, and the moving part may move from an insertable and ejectable position to an insertion completion position. In ejecting the card, the moving part may move from the insertion completion position to the insertable and ejectable position, and the abutting member may push the card in the ejecting direction of the card.

A card reader may include a card insertion slot into which the card is inserted; a metal detecting mechanism structured to detect the external connection terminal of the card inserted into the card insertion slot; a jamming magnetic field generation mechanism structured to generate a magnetic field for prevention of fraudulently reading a magnetic datum recorded in the magnetic stripe; and a control unit. The metal detecting mechanism may include an exciting coil and a detecting coil. The jamming magnetic field generation mechanism may include a jamming magnetic field generating coil. The control unit may be structured to alternately switch between a current supply to the exciting coil and a current supply to the jamming magnetic field generation coil, and detect the external connection terminal on the basis of an output from the detecting coil at a time when the exciting coil is supplied with a current.

A card processing apparatus detects an insertion/non-insertion of a card and a position of an inserted card regardless of any existence/non-existence of an opaque part on any position of the card. A first card detector is disposed at a first position in a conveying path, a second card detector is disposed at a second position after the first card detector, and a third card detector is disposed at a third position in the conveying path. A conveying mechanism is controlled by detection signals outputted from the first to third card detectors. Each of the card detectors include an operating member movable from a standby position to a shifted position due to contact with the card. A sensor detects any displacement of the operating member, wherein one of the detection signals provides a detection/non-detection of a card, an insertion or non-insertion of a card and an inserted card position.
