Description

  The present invention relates to a non-contact type terminal device that communicates with a value holding medium such as an IC card having an IC chip in a non-contact state, and reads and writes an IC chip.

  In recent years, with the progress of cashless and the spread of electronic money, various services and systems using IC cards as value holding media have been provided in various fields such as distribution. Among them, non-contact type IC cards are attracting attention especially in terms of ease of use. In addition, electronic value information (electronic value) of electronic money and electronic tickets (commuter pass, boarding ticket, airline ticket, etc.) is stored in an ultra-small IC chip built in the non-contact type IC card. Various payments, such as payments at ticket vending machines at stations, payments at vending machines such as beverages, payments at stores, admission to various facilities, etc. are considered.

  When such an IC card is used, wireless communication is generally performed in a non-contact state with respect to the IC card, and information recorded on the internal IC chip is read or new information is written to the IC chip. A reader / writer device as a contact type terminal device is used (for example, see Patent Document 1 and Patent Document 2).

  Such a reader / writer device includes a reading surface (reading unit) having an antenna capable of wireless communication with an IC chip. Then, the holder of the IC card can perform various payments using the electronic money described above by reading and writing the IC chip while holding the IC card close to the reading surface. Further, whether reading and writing of the IC chip is completed, that is, whether or not settlement of electronic money is completed can be easily determined by checking the contents of the display unit provided in the reader / writer device.

  In recent years, IC card functions include payments at vending machines at stations, payments at vending machines for beverages, payments at stores, admission to various facilities, etc. Has also been realized. When the processing is completed only by communication between the IC card and the reader / writer device, a processing error hardly occurs even if the time for holding the IC card is extremely short. However, for example, when various payments are made with a credit function or the like, it is necessary to communicate with a center or the like in order to authenticate an IC card or the like. For this reason, it takes time for communication with another place, and if the time for holding the IC card is extremely short, a processing error may occur.

  For this reason, it is proposed to provide a card holder in the reading unit of the reader / writer device so as to mechanically hold the IC card, or to hold the IC card for a predetermined time by using an electric force or a magnetic force. (For example, see Patent Document 3 and Patent Document 4).

However, when the IC card is mechanically held, it is not possible to take advantage of the characteristics of the non-contact type IC card such that processing can be performed simply by holding it. In addition, since non-contact type IC cards also have a degree of freedom in shape, it is expected that shapes of various designs will appear in the future, and cannot be applied to shapes that cannot be mechanically held. Such a problem will occur. Furthermore, when electrical or magnetic force is used, the non-contact IC card originally uses radio for mutual communication (action). There was a risk of occurrence.

  FIG. 1 is an external view of a contactless terminal device according to an embodiment of the present invention, FIG. 2 is a view taken along the line II-II in FIG. 1, and FIG. 4 is a schematic block diagram of the contact type terminal device, FIG. 4 is a conceptual state of the pressure generating means, FIG. 5 is a description of the holding state of the IC card, and FIGS. 6 and 7 are schematic flows for explaining the operating state of the pressure generating means. FIG. 8 shows a state in which a value holding medium of another aspect is held. 9 to 13 show schematic configurations representing other forms of pressure generating means.

  The non-contact terminal device of the present invention will be specifically described with reference to FIGS.

  As shown in FIG. 1, a non-contact type terminal device 1 has an IC chip 2 that has a readable / writable IC chip 2 and transmits information in a non-contact state to an IC card 3 as a value holding medium formed in a rectangular shape. 2 can communicate with each other.

  As shown in FIGS. 1 to 3, the non-contact type terminal device 1 includes a holding unit 10 and a terminal body unit 15. The holding unit 10 includes a reading surface 5 on which the IC card 3 is approached on the front surface, a pressure setting means 6 that is disposed on the back surface side of the reading surface 5 and generates a holding force on the reading surface 5 side of the IC card 3; And a wireless communication unit 8 having an antenna substrate 7 as an antenna unit capable of wirelessly communicating information with the IC chip 2. The terminal body unit 15 controls the operation of the wireless communication unit 8 and performs data processing and recording of the IC chip 2 via the antenna substrate 7, and the pressure setting means 6 according to the operation status of the payment module 11. The control part 12 which controls the action | operation of is provided. Although the operation of the pressure setting means 6 is controlled according to the operation of the settlement module 11, it can be controlled according to the capture of the IC chip 2 or can be controlled so that it always operates. is there.

  In the non-contact type terminal device 1 of the present embodiment, the holding unit 10 and the terminal body unit 15 are wiredly connected by a cable 16, and the holding unit 10 can be separated from the terminal body unit 15. Note that the cover unit 10 and the terminal main unit 15 can be formed integrally.

  As shown in FIG. 2, the holding unit 10 includes a plastic case 20, and the case 20 has a predetermined inclination angle (for example, 30 degrees) with respect to the lower case 21 that can be placed on the placement surface and the placement surface. The upper case 22 is fitted to the upper side of the lower case 21 with an inclination angle of 2 mm. As shown in FIGS. 1 and 2, a part of the surface of the upper case 22 is a reading surface 5.

  The reading surface 5 is formed with a light surface 23 that emits light on the surface of the reading surface 5 in a shape corresponding to the outer shape of the IC card 3, that is, a rectangular shape. The light surface 23 surrounds the periphery of the antenna substrate 7. It is formed in a slit shape. In the upper case 22, areas other than the light surface 23 are optically shielded.

  The pressure setting means 6 lowers the pressure between the antenna substrate 7 and the reading surface 5 relative to the pressure between the reading surface 5 and the IC card 3, that is, between the antenna substrate 7 and the reading surface 5. Is configured to generate a holding force to the reading surface 5 side of the IC card 3.

  Specifically, an air flow path 51 as a fluid flow path is provided between the reading surface 5 and the antenna substrate 7, and the air flow path 51 gradually changes in cross-sectional area from the right side to the left side in the drawing. It has a shape. That is, a wing-shaped flow path plate 53 swelled on the reading surface 5 side is provided, and the flow path plate 53 is provided with a side wall (not shown) so that the air in a closed cross-sectional state in which the inlet and outlet portions are open. A flow path 51 is formed.

  More specifically, in the air flow path 51, the flow path cross-sectional area gradually changes from the inlet part to the middle part corresponding to the position immediately below the IC card 3, and the flow cross-sectional area gradually changes toward the outlet part. It is like that. Thereby, the flow velocity of air gradually increases from the inlet portion toward the middle portion, the flow velocity decreases toward the outlet portion, and the place where the flow velocity is the fastest can be appropriately arranged (the generation center of the negative pressure). The clearance dimension of the air flow path 51 is set to, for example, about 5 mm at the inlet and about 15 mm at the outlet. Since the air flow channel 51 is provided with the flow channel plate 53 so as to have a wing shape, the upper surface of the flow channel becomes round, and even if the angle at which the IC card 3 is placed is slightly deviated, a negative pressure is applied and the holding can be performed reliably. .

  A fan 52 as a fluid supply means is provided in the vicinity of the air flow path 51 on the narrow cross-sectional area side (inlet side). An air flow toward the exit side is formed. The fan 52 is provided in advance as a cooling fan used for cooling the equipment in the terminal body unit 15. Note that the flow path plate 53 at the end of the air flow path 51 on the outlet side may be formed with protrusions, dimples, and the like for smooth discharge of the air flow. By forming protrusions and dimples, a vortex is generated, and the air flow is drawn out by the vortex, so that the air flow is smoothly discharged.

  Based on FIG. 4, a mechanism for generating a holding force toward the reading surface 5 side of the IC card 3 will be described.

  FIG. 4A conceptually shows the air flow path 51. As shown in the drawing, an air flow path 51 is formed by a flow path plate 53 and a side wall 54, and air is sent from an inlet side 55 which is a side having a small cross-sectional area, toward an outlet side 56 which is a side having a wide cross-sectional area. An air flow is formed. As shown in FIG. 4B, the air flow from the inlet side 55 flows from the narrow channel cross-sectional area toward the wide side, and the flow velocity gradually increases. Due to this air flow, a negative pressure is generated in the air flow path 51, and the pressure between the antenna substrate 7 and the reading surface 5 is made relatively lower than the pressure between the reading surface 5 and the IC card 3. Due to Bernoulli's law, a downward force F (holding force) acts on the IC card 3 on the reading surface 5, and the IC card 3 is sucked onto the reading surface 5 and held on the reading surface 5.

  Since the flow path plate 53 has a wing shape that swells toward the reading surface 5 side, as shown in FIG. 5A, when the IC card 3 is held close to the inlet side 55, it is shown in FIG. 5B. As described above, when the IC card 3 is held over the central portion, as shown in FIG. 5C, the reading surface 5 can be used in any case where the IC card 3 is held close to the exit side 56. A downward force F (holding force) can be effectively applied to the upper IC card 3.

  For example, when the reading surface 5 is opened on the upper surface side and the IC card 3 is placed on the reading surface 5, an air flow path 51 having a closed cross section is formed, and a negative pressure is generated between the antenna substrate 7 and the reading surface 5. It is like that. For this reason, when IC card 3 gets on, fluid flows well and it can generate negative pressure efficiently.

  The antenna substrate 7 described above is formed, for example, so that a transmission coil pattern and a reception coil pattern are adjacent to each other on the surface, and is electrically connected to the RF substrate 28 shown in FIG. 2 by wiring. . A transceiver unit 29 is mounted on the RF substrate 28, and the transceiver unit 29 and the antenna substrate 7 constitute a wireless communication unit 8.

  As shown in FIGS. 1 to 3, the holding unit 10 includes a display unit 30 that displays the contents of the IC chip 2 and a speaker 31 that outputs sound from the vicinity of the reading surface 5. The display unit 30 is provided on the surface of the upper case 22 so as to be adjacent to the light surface 23, and the display unit 30 is electrically connected to the circuit board 27 via the I / O module 26. The speaker 31 can output sound through a sound hole 32 formed on the surface of the upper case 22 so as to be adjacent to the display unit 30. Like the display unit 30, the speaker 31 is an I / O module 26. Is electrically connected to the circuit board 27 via In addition, the speaker 31 is controlled so as to output different sound according to a control signal from the control unit 12.

  As shown in FIGS. 1 and 3, the terminal body unit 15 can be placed on the placement surface and has a predetermined inclination angle (for example, an inclination angle of 30 degrees) with respect to the placement surface. 35. The settlement module 11 and the control unit 12 are provided in the case 35.

  Further, the terminal body unit 15 includes an operation key 36 including a plurality of buttons capable of inputting information such as an amount of money, and displays various information such as information input by the operation key 36 and data in the IC chip 2. A portion 37 is provided. Furthermore, a printer unit 38 capable of printing information displayed on the display unit 37 on paper and a modem unit 39 capable of connecting and transmitting information recorded in the settlement module 11 to an external organization are provided.

  The modem unit 39 is connected to an IP network via a third party in addition to connecting and communicating with a modem for communication transmission / reception installed directly in an external organization, and via communication means such as the Internet. It is also possible to send it to an external organization.

  The display unit 37, the printer unit 38, and the modem unit 39 are integrally controlled by the control unit 12 in accordance with an input from the operation key 36. The settlement module 11 is electrically connected to the RF board 28 via the cable 16, and the control unit 12 is electrically connected to the circuit board 27 via the cable 16. The control unit 12 has a function of outputting sound to the speaker 31.

  A case where electronic payment is performed by the IC card 3 using the non-contact type terminal device 1 configured as described above will be described.

  By turning on the power button from the operation key 36, a self-diagnosis (self-test) is performed to determine whether each function is normal. For example, it is confirmed whether the connection state between the cover unit 10 and the terminal body unit 15 is normal, or the payment module 11 itself diagnoses whether its function is normal. Note that the self-test is not limited to the diagnostic content, and can be set arbitrarily. Further, during the self-test, for example, “Self-diagnosis” is displayed on the display unit 37 of the terminal body unit 15.

  As a result of the self-test, when it is determined that there is an abnormality or failure, “error” is displayed on the display unit 37 of the terminal body unit 15. In response to this, the operator of the non-contact type terminal device 1 confirms the electrical connection state of the cable 1 or the like, or performs predetermined measures such as searching for a fault location. On the other hand, when it is determined that the input is normal, the state waits for input from the operation key 36. At this time, the power can be shut off by turning off the power button of the operation key 36.

  For example, when the holder of the IC card 3 purchases an item with a price of 1000 yen, the operator of the operation key 36 inputs the amount information of 1000 yen with the operation key 36. The control unit 12 determines whether the instruction from the operator is an instruction, that is, what kind of signal is the input signal from the operation key 36 and performs control according to the determination. For example, in the case described above, a signal is sent to the settlement module 11 so as to perform a settlement process of 1000 yen in response to an input signal from the operation key 36. If the input signal from the operation key 36 is a power OFF signal, the termination process is executed. If the input signal from the operation key 36 is a signal for performing various settings and management of the terminal body unit 15. Executes setting / management processing.

  When the control unit 12 determines that the payment process is to be performed, the control unit 12 displays the input amount on the display unit 37 of the terminal body unit 15. The operator confirms that an accurate input has been made with the amount displayed on the display unit 37, and then presses the confirmation button with the operation key 36. In response to this, the control unit 12 transmits money amount information to the settlement module 11. Further, a control signal is sent through the cable 16 and the circuit board 27 so that the light is turned on from the light surface 23. On the other hand, when the amount information is input, the settlement module 11 places the transmission / reception unit 29 in a standby state and waits for an input from the antenna board 7.

The holder of the IC card 3 can easily hold the IC card 3 over the reading surface 5 by guiding the blinking light through the light surface 23. When the IC card 3 is held over the reading surface 5, the transmitting / receiving unit 29 reads information recorded on the IC chip 2 of the IC card 3 via the antenna substrate 7 by wireless communication and transmits the information to the settlement module 11. The settlement module 11 performs data processing of the IC chip 2 that has been sent.
That is, the amount of 1000 yen inputted by the operation key 36 is subtracted from the saving amount recorded in the IC chip 2, and a new saving amount (balance) is calculated to perform settlement processing. After the settlement process is completed, a new saving amount is written (overwritten) in the IC chip 2 via the transmission / reception unit 29 and the antenna substrate 7. At the same time, the payment module 11 notifies the control unit 12 that the payment has been completed normally. The end can be notified by sound or light.

  On the other hand, similarly to the display unit 30 of the cover unit 10, the control unit 12 uses the purchase amount that has been settled, that is, the amount input by the operation key 36 and the new saving amount as a settlement result, and displays the display unit 37 of the terminal body unit 15. To display. After confirming the display on the display unit 37 again, the operator prints out the settlement result by the printer unit 38.

  The settlement result printout is used as a receipt for the holder as well as for the operator. Further, the control unit 12 may be set so that the settlement result is displayed on the display unit 37 and at the same time the settlement result is automatically printed out by the printer unit 38. If the payment does not end normally and, for example, a payment abnormality occurs due to some reason, for example, communication failure, the payment abnormality can be notified by sound or light.

  Further, the data of the IC chip 2 recorded in the settlement module 11 can be transmitted to the external organization periodically by the operator, for example, once every evening in the evening. That is, the modem unit 39 can communicate with a communication receiving modem (not shown) installed in an external organization and transmit data. As described above, the modem unit 39 may be connected to the IP network via the third party organization, and may be transmitted via communication means such as the Internet. For example, when a credit function is added to the IC card 3, it is possible to perform credit settlement by communicating with the center by means of communication means using the modem unit 39.

  In the non-contact type terminal device 1 described above, when air is sent to the air flow path 51 by the fan 52, a negative pressure is generated in the air flow path 51, and the antenna against the pressure between the reading surface 5 and the IC card 3 is generated. The pressure between the substrate 7 and the reading surface 5 is relatively lowered, a downward force F (holding force) acts on the IC card 3 on the reading surface 5, and the IC card 3 is attracted to the reading surface 5 to read the reading surface. Held at 5. Since the fan 52 is provided as a fan for cooling the device, air can be sent to the air flow path 51 by using the exhaust of the fan 52 that has acted as a cooling fan.

  That is, the cooling fan generally operates when the power consumption increases when the wireless circuit operates. By using the fan 52 that is used as a cooling fan, the operation of the fan 52 starts when the wireless circuit is activated, air is sent to the air flow path 51, and the IC card 3 is sucked to the reading surface 5 to be read surface 5. Is held. When the wireless circuit is deactivated, the cooling fan is stopped, the fan 52 is stopped, the air flow disappears, and the hold of the IC card 3 is released. For this reason, it is possible to perform a desired holding operation without specially preparing means for controlling the air flow.

  Specifically, as shown in FIG. 6, when the procedure is started by operating a processing key to start the procedure (S1), the fan 52 is turned on (S2). Air is sent to 51, and the IC card 3 is sucked to the reading surface 5 and held on the reading surface 5. Processing such as settlement processing is executed in a state where the IC card 3 is held (S3), and the procedure is terminated by, for example, ending the procedure by operating the processing end confirmation button (S4). At the end of the procedure, the fan 52 is turned off (S5), the air flow is lost, and the hold of the IC card 3 is released.

  It has been confirmed that the IC card 3 is held on the reading surface 5 when the flow velocity of the air flow by the fan 52 is 0.5 m / sec or more at the entrance, for example. Preferably it is 2 m / sec or more. If the flow velocity is too high, there is an influence of noise and wind on the surroundings, so 0.5 m / sec to 4 m / sec is appropriate, and more preferably 0.5 m / sec to 2 m / sec is optimal. .

  Since the IC card 3 is attracted to the reading surface 5 by flowing air, the IC card 3 can be reliably held with relatively little power without generating abnormal noise.

  The fan 52 can be operated at all times, and can be operated while the holder of the IC card 3 is detected and detected.

  Therefore, the IC card 3 can be easily held on the reading surface 5 without using mechanical holding means and without affecting communication, and communication with the outside is required to some extent. Even in the case of processing having processing time (for example, authentication processing for using the credit function), communication with the IC card 3 is reliably performed, and there is no possibility that an error or the like occurs.

  An example of another process will be described based on FIG. The example shown in FIG. 7 is based on the premise that a credit function is added as the IC card 3, and shows a case of processing to select and execute the withdrawal of the cash charged in the IC card 3 and the credit settlement. is there. That is, only when credit payment is selected, communication with the outside (online processing) is required and a certain amount of processing time is required. Therefore, the fan 52 is operated to send air to the air flow path 51, and the IC card 3 It is held on the reading surface 5. When cash withdrawal is selected, communication with the terminal body unit 15 (offline processing) is required, so extremely short processing time is required. Set to the released state.

  Specifically, as shown in FIG. 7, it is determined whether or not credit settlement is selected by operating a processing key (S11). If it is determined in S11 that credit settlement is not performed, offline processing ( In S12), the process in a state where the fan 52 is stopped is executed. If it is determined in S11 that the credit settlement is made, the fan 52 is turned on (S13), air is sent to the air flow path 51, and the IC card 3 is sucked to the reading surface 5 and held on the reading surface 5. Online processing and offline processing are executed in a state where the IC card 3 is held (S14), and the procedure ends (S15), for example, by operating the processing end confirmation button. At the end of the procedure, the fan 52 is turned off (S16), the air flow is lost, and the hold of the IC card 3 is released.

  Therefore, when a credit settlement requiring a certain amount of processing time is selected, the IC card 3 is held on the reading surface 5, and communication with the IC card 3 is surely performed with minimum power, and an error or the like may occur. Disappears.

  Even in the case of the IC card 3 to which the credit function is added, the IC card 3 may be held on the reading surface 5 even in the case of offline processing by always turning on the fan 52.

  Since the non-contact type terminal device 1 of the present invention can hold the IC card 3 reliably by flowing air, the value holding medium is not limited to a card-like one, as shown in FIG. Even the mobile phone 61 can be securely held on the reading surface 5. That is, the range of the shape of the value holding medium that can be handled can be greatly expanded.

  Another embodiment of the pressure generating means will be described with reference to FIGS. The same members as those shown in FIGS. 1 to 8 are denoted by the same reference numerals, and redundant description is omitted.

  In the pressure generating means shown in FIG. 9, the flow path plate 62 forming the air flow path 51 is formed in a flat shape and is inclined. For this reason, the air flow path 51 can be comprised by the flow-path board 62 of a simple shape.

  The pressure generating means shown in FIG. 10 has a fan 52 directly provided on the inlet side 55 of the air flow path 51. For this reason, there is almost no pressure loss, and a reliable air flow can be generated with less power.

  The pressure generating means shown in FIG. 11 is configured such that a fan 52 is provided at the lower portion of the inlet side 55 and air is sent from the inlet side 55 into the air flow path 51 via the introduction path 63. For this reason, the space near the inlet side 55 of the air flow path 51 can be used effectively, and the degree of freedom in designing the reading surface 5 side can be increased.

  The pressure generating means shown in FIG. 12 is applied to a holding unit 66 having a reading surface 65 that is nearly vertical. A wing-shaped channel plate 67 is arranged in the vertical direction, and the lower side of the air channel 69. Are provided with a fan 68. For this reason, by supplying air upward, air can be easily discharged and the IC card 3 can be held securely.

  It is also possible to arrange the fan 68 on the upper side by disposing the channel plate 67 upside down.

  The pressure generating means shown in FIG. 13 is not configured to form a pressure difference by an air flow, and air blowing ports 71 facing the upper surface of the reading surface 5 are arranged in one direction so that air is directly applied to the upper surface of the IC card 3. The pressure between the reading surface 5 and the IC card 3 (pressure on the upper surface side of the IC card 3) is made higher than the pressure between the antenna substrate 7 and the reading surface 5 by jetting. For this reason, the IC card 3 can be directly pressed against the reading surface 5 side, and the hold can be performed more reliably.

  As another pressure generating means, a suction means may be provided on the back side of the reading surface 5 so that the IC card 3 is directly sucked and held on the reading surface 5.

  In the non-contact type terminal device described above, the IC card 3 can be easily held on the reading surface side without using mechanical holding means and without affecting communication.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of a non-contact type terminal device that communicates in a non-contact state with a value holding medium such as an IC card having an IC chip, and reads and writes the IC chip.
