Abstract: A communication device having a function for supplying electric power to a communication partner may include a non-contact control section configured to balanced-output transmission power, an antenna circuit configured to transmit the transmission power as an electromagnetic wave, and a matching circuit which is disposed between an output of the non-contact control section and an input of the antenna circuit and is configured to perform impedance matching. The matching circuit and the antenna circuit are respectively provided with two systems and circuit structures from the output of the non-contact control section to the antenna circuits via the matching circuits of the two systems are formed symmetrically.

Abstract: A non-contact communication module may include a substrate including an antenna including an antenna coil placed annularly in the substrate, and a ground pattern for grounding formed in the substrate; an antenna-side land that is formed on an external surface of the substrate, and is electrically connected to the antenna; and a ground-side land that is formed on the external surface of the substrate, and is electrically connected to the ground pattern. A distance between the antenna-side land and the ground-side land may be such that the antenna-side land and the ground-side land can be connected by use of a solder bridge.

Abstract: A non-contact type information processing device may include a flat plate-shaped substrate on which a communication antenna formed in a ring shape and a signal processing circuit part electrically connected with the communication antenna are mounted; and a connector member structured to electrically connect a host device on which the non-contact type information processing device is mounted with the non-contact type information processing device. The signal processing circuit part may be mounted on the substrate on an outer peripheral side relative to the communication antenna formed in the ring shape; and the connector member may be mounted on the substrate on an inner peripheral side relative to the communication antenna formed in the ring shape so that an inserting direction of a second connector member which is inserted and connected with the connector member is substantially parallel to a thickness direction of the substrate.

Abstract: A contactless IC card reader and a data reading method which are capable of improving data reading accuracy while preventing a decrease in processing speed. Specifically, in a contactless IC card reader which transmits signals composed of amplitude modulated carrier signals to a contactless IC card, the contactless IC card and reader communicate by means of an NRZ encoding method and an ASK modulating method for which the modulation depth has an arbitrary value. The contactless IC card reader is provided with a contactless control means which modulates/demodulates signals transmitted to/received from the contactless IC card, and a main control means which is electrically connected to the contactless control means and that controls the entire card reader. The modulation depth that is varied by the contactless control means based on the command sent from the main control means has multiple range widths with an arbitral value as the standard.

Abstract: A non-contact information processing device and a non-contact card medium issuing machine that can easily and quickly judge whether an electromagnetic radiation function of a non-contact communication antenna is working properly or not. Concretely to describe, provided is a card reader that includes non-contact information processing for recording and/or reproducing information through electromagnetic induction without contacting a card medium; and a transfer path for transferring the card medium. The non-contact information processing has a device-side non-contact communication antenna that is able to send and receive information to/from a medium-side non-contact communication antenna provided on the card medium. Provided is detection for detecting if the device-side non-contact communication antenna is working normally.

Abstract: A card reader may include a reader-side non-contact communication antenna, a transfer path through which a card is transferred, a transfer mechanism to transfer the card, a controller to control the transfer mechanism, and a regulator to regulate transfer of the card. The reader-side antenna may be provided proximate to the transfer path. The regulator may be positioned such that the reader-side antenna can communicate with a card-side antenna on the card. The controller may control the transfer mechanism to move the card closer to the regulator or away from the regulator after the card has stopped once, so as to enable communication between the reader-side antenna and the card-side antenna.
