  • Patent number: 7740174
    Abstract: A technology that is applicable generally to manual noncontact card readers regardless of whether they are of insertion or swipe type, and realizes stable communication even with antennas of small size is provided. A pair of loop antennas is located in opposition to either side of a transport path, in proximity to a card insertion slot of the transport path. A magnetic circuit which connects the loop antennas together is located so as to not lie exposed in the transport path, so that, of the magnetic fluxes produced in two directions with respect to the noncontact card from the loop antennas, one of these will be diverted through the magnetic circuit without interlinking to the card.

  • Publication number: 20100031154
    Abstract: A plurality of servers each transmit data of an initial screen to be displayed on a display screen of radio equipment at a predetermined time interval. The radio equipment is in a reception waiting mode until it is connected to any one of the servers, and is performing channel scanning. Once the data of the initial screen transmitted from any one of the servers is received by the radio equipment, the radio equipment displays the initial screen on the display screen based on the received data. When an operation of a connection instruction is performed on the initial screen, the radio equipment is connected to the server corresponding to the initial screen.

  • Patent number: 7506814
    Abstract: A card reader which makes it possible to read card data from a non-contact IC card, discharge a foreign substance inserted from a card insertion slit, sufficiently ensure the degree of freedom in design, and sufficiently prevent the size of the apparatus main body from becoming large. A coil-shaped circuit pattern is formed on an antenna substrate used as an antenna for radio communication with a non-contact IC card. A part located inside the coil-shaped circuit pattern is cut out to form an opening. Even if the antenna substrate is disposed below the card reader main body, therefore, a foreign substance such as a coin inserted from an insertion slit may be discharged from the opening of the antenna substrate.

  • Patent number: 7377434
    Abstract: A card processor which can substantially reliably prevent magnetic data recorded in a magnetic card and can remarkably enhance security. In the card processor, two radiation sources radiate disturbing magnetic fields outside of an insertion slot. A disturbing magnetic field radiated from one radiation source and a disturbing magnetic field radiated from the other radiation source have different frequencies and intensities. Accordingly, even when a differential head is located at such a position as to be influenced by the disturbing magnetic fields, it is substantially impossible to attain such balance adjustment as to eliminate the influences of the disturbing magnetic fields.

  • Patent number: 7173573
    Abstract: An insertion-port loop antenna has a wide communication region for a non-contact type IC card inserted into an insertion port of a card reader, etc. An insertion-port loop antenna is mounted in the vicinity of an insertion port, through which a non-contact type communication medium is inserted. The insertion-port loop antenna comprises two loops. An upper loop is arranged above a long side of the insertion port. A lower loop is arranged below the long side of the insertion port. The two loops are opposite to each other in a direction of winding. Thereby, magnetic flux is generated between the upper loop and the lower loop. The magnetic flux is generated in front of the insertion port. Therefore, it is possible to begin communication before the non-contact type IC card is inserted into the insertion port.

  • Patent number: 6952167
    Abstract: An output of a resonant circuit 60 which electromagnetically couples with an external communications apparatus is rectified and taken out, and a resultant output voltage V is monitored by a switch control circuit 61. After the output voltage V has risen to or beyond a threshold Vth1, a switch element SW is turned on and off, and a state of the switch element SW in which the output voltage V becomes higher is determined. While holding the switch element SW in the state thus determined, a power supply switch element PSW is turned on when the output voltage V has further risen. As a result, even when a plurality of noncontact IC cards 6 overlaid with one another are brought close to the communications apparatus, the individual noncontact IC cards 6 can carry out data communication.

  • Patent number: 5960335
    Abstract: A radio communication apparatus according to the present invention is provided with first and second correction tables for correcting the measurement values of RSSI information by reception condition. The apparatus measures not only the RSSI information of the radio channel in a reception period of the radio channel assigned to itself by a TDMA scheme but also the reception period of the other radio channels in an idle period, and then corrects the RSSI information measurement values on the basis of the first and second correction tables. The corrected RSSI information measurement data is reported to the base station for MAHO.

  • Patent number: 5802039
    Abstract: Disclosed is a mobile radio communication apparatus having a sync restoring control function equipped in a controller. When disconnection of reception is detected during communication, the sync restoring control function sends a sync acknowledge indicate signal to a digital demodulator within a cutoff allowance period to re-establish synchronized reception. The bit error rate is detected during communication, and a BER code indicating this bit error rate is displayed on a display.

  • Patent number: 5794222
    Abstract: A mail processing system includes mail processing devices such as postage meters, a sorting machine and a host computer. Each mail processing device provides to each outgoing mail not only its mailing charge but also an indicator which identifies the device itself, storing such provided data in its memory device. The sorting machine reads from each received mail the data provided to it and stores such data in its memory device according to the device-identifying indicator. The computer serves to retrieve data from these memory devices to make comparisons. If the discrepancy is greater than a specified value, a warning signal is outputted as a fraud has been committed.

  • Patent number: 5710986
    Abstract: A radio communication apparatus of this invention includes a mode designation switch for selectively designating and inputting a desired mode from an analog mode and a digital mode, and a mode storage circuit for storing the desired mode designated and input by the mode designation switch and has a mode setting control function, a mode comparison function, and a mode change control function. In order to establish a radio link, control is performed to set a mode for transmitting a communication signal in accordance with the desired mode stored in the mode storage circuit. After the start of transmission of the communication signal, the mode comparison function compares the mode set by the mode setting control function with the desired mode stored in the mode storage circuit.
