Japanese Patent No. 3637821

  By the way, in the above portable terminal (non-contact communication terminal), when performing non-contact communication with a non-contact communication medium such as an IC card, non-contact communication is performed with respect to the portable terminal depending on the application. There are assumed a case where communication should be performed with a medium on the side and a case where communication should be performed close to a non-contact communication medium from the mobile terminal side. For example, in payment applications that pay for products, etc., the customer side is the main player for handling electronic money and credit cards with a large monetary value, and the IC card is placed on a display device provided on a portable terminal. In many cases, hesitates to communicate. On the other hand, in the confirmation of lift tickets performed at the lift platform of ski resorts and the use of rigging performed in facilities such as movie theaters, it is important to complete the confirmation work smoothly and quickly, so the confirmer (terminal operator) In many cases, the mobile terminal communicates close to a non-contact communication medium to be communicated. Thus, since a communication aspect changes with uses, the portable terminal which can respond to these various uses is desired.

  In order to meet such needs, for example, it may be possible to individually design a mobile terminal suitable for each application, but such a method increases the cost of design and development. There is. In addition, when a plurality of uses are assumed as described above, there is a problem that a mobile terminal designed for each use must be prepared.

  For example, in the device of Patent Document 1, since the antenna unit is provided on the side opposite to the surface on which the display device is provided, the terminal itself is brought close to the reading object (lift ticket, ticket, etc.) as in the case of rigging. Since the antenna on the opposite side can be brought closer to the object to be read without changing the device posture from the normal posture where the display device is facing upward, it is not necessary to change the way it is held, making it suitable for the above-mentioned cutting applications. It can be said that. However, this configuration has a problem that it is difficult to communicate with an IC card or the like from the display device side, and is not suitable for a settlement application. In particular, in payment applications, because the use of non-contact communication media (such as IC cards with electronic money function) having a monetary function, the device operator does not read the device close to the non-contact communication medium. It is necessary for the customer side to voluntarily and easily deceive the non-contact communication medium with the intention of the customer side.

  Therefore, in the portable terminal provided with the antenna unit on the opposite side of the display device as described above, when reading the non-contact communication medium, the device is turned over from the normal posture (the device posture with the display device side facing upward). The operability will be very poor. In addition, if reading is performed by turning it upside down in this manner, the display screen will be arranged downward this time, so that the customer or user cannot check the display device at the time of reading. Therefore, it is difficult to use the above-described configuration for a settlement application that requires immediate confirmation of the settlement amount and settlement processing at the time of settlement. For these reasons, conventionally, in order to smoothly perform the payment application, it has been necessary to separately prepare a terminal suitable for the application.

  As another method, a large number of antennas for communicating with a non-contact communication medium may be arranged at various locations in the terminal. In this way, the degree of freedom of arrangement of the non-contact communication medium is increased, so that applicability to a plurality of uses is increased. However, with this configuration, disadvantages due to an increase in the antenna arrangement area are unavoidable, and this is particularly disadvantageous in terms of cost.

  The present invention has been made in order to solve the above-described problems, and in a portable terminal having a non-contact communication function, even when a non-contact communication medium is placed on the terminal side and communication is performed, the terminal is in non-contact communication.

This is the same as the embodiment. Hereinafter, other differences from the second embodiment will be mainly described. In addition, the same code | symbol is attached | subjected to the component substantially the same as the said 2nd Embodiment, and the description is abbreviate | omitted.

  FIG. 4A is a perspective view schematically illustrating a mobile terminal according to the third embodiment, and FIG. 4B is an explanatory diagram illustrating an electrical configuration of a case upper side terminal and a case lower side terminal. It is. FIG. 5A is an explanatory view schematically illustrating the configuration of the antenna side terminal, the case upper side terminal, and the case lower side terminal, and FIG. 5B shows the state where the antenna unit is mounted on the case. It is explanatory drawing shown.

  In the third embodiment, as shown in FIG. 4A, case upper terminals 35a, 35b, 35c, and 35d are provided above the groove 34 on one side in the width direction (−Z-axis direction) provided in the case 302. Case lower terminals 36a, 36b, 36c, 36d are provided below the groove 34. As shown in FIG. The case upper side terminal 35d and the case lower side terminal 36a are connected to the detection unit 7 so that a conduction state with a terminal (antenna side terminal 57d) provided on the antenna unit 350 side is output to the detection unit 7. It has become. The case upper side terminal 35a and the case lower side terminal 36d are connected, and the case upper side terminal 35b and the case lower side terminal 36c are connected, and are connected to the non-contact communication unit 20, respectively. A signal from the non-contact communication unit 20 is output to the antenna unit 350 side. The case upper side terminal 35c and the case lower side terminal 36b are grounded. The case upper terminals 35a to 35d and the case lower terminals 36a to 36d correspond to an example of “case side terminals”.

  In addition, antenna-side terminals 57a, 57b, 57c, and 57d that can be electrically connected to the case upper terminals 35a to 35d and the case lower terminals 36a to 36d are provided in the vicinity of the convex portion 56a of the antenna unit 350. . The antenna side terminals 57 a and 57 b are connected to the antenna 51. The antenna side terminals 57c and 57d are short-circuited with each other. As shown in FIG. 5, the antenna-side terminal 57 (57a to 57d) is attached to the attachment portion 55a via a spring 58. Further, when the antenna unit 350 is attached to the case 302, the protruding state of the antenna side terminal 57 changes due to elastic deformation of the spring 58, and the case upper side terminal 35 (35a to 35d) or the case lower side terminal 36 ( 36a-36d).

  In the antenna unit 350 configured as described above, an H level signal is input to both P1 and P2 of the detection unit 7 when the antenna unit is not attached. Thereafter, as shown in FIG. 4A, in a state where the antenna fixing portion 54 is arranged on the upper side of the case 302, the pair of mounting portions 55a and 55b are slid into the pair of groove portions 34 so that the antenna unit 350 is When held at the upper surface position, the antenna side terminal 57a contacts the case upper side terminal 35a, the antenna side terminal 57b contacts the case upper side terminal 35b, and the antenna side terminal 57c contacts the case upper side terminal 35c. The antenna side terminal 57d is in contact with the case upper side terminal 35d. The state where the antenna side terminals 57a to 57d and the case upper side terminals 35a to 35d are connected in this way is referred to as a first connection state. At this time, the case upper side terminals 35c and 35d connected to the antenna side terminals 57c and 57d are short-circuited, so that the signal input to P1 of the detection unit 7 changes from the H level to the L level. On the other hand, the signal input to P2 remains at the H level. At this time, the detection unit 7 outputs a signal (first signal) that can specify that P1 is at the L level and P2 is at the H level to the control unit 6, and the control unit 6 outputs this signal (the first signal). ), It is determined that the antenna unit 350 is being held at the upper surface position (first connection state).

  Further, when the antenna fixing portion 54 is arranged on the lower side of the case 302, the pair of mounting portions 55a and 55b are slid into the pair of groove portions 34 and the antenna unit 350 is held at the lower surface position. The terminal 57a is in contact with the case lower side terminal 36d, the antenna side terminal 57b is in contact with the case lower side terminal 36c, the antenna side terminal 57c is in contact with the case lower side terminal 36b, and the antenna side terminal 57d is in the case lower side terminal 36a. Contact with. The state where the antenna side terminals 57a to 57d and the case lower side terminals 36a to 36d are connected in this way is referred to as a second connection state. At this time, since the case lower side terminals 36a and 36b connected to the antenna side terminals 57c and 57d are short-circuited, the signal input to P2 of the detection unit 7 changes from the H level to the L level. On the other hand, the signal input to P2 becomes H level. At this time, the detection unit 7 outputs a signal (second signal) that can specify that P1 is H level and P2 is L level to the control unit 6, and the control unit 6 receives this signal. In addition, it is determined that the antenna unit 350 is in a state of being held at the lower surface position (second connection state). The detection unit 7 and the control unit 6 that determine which state is the first connection state or the second connection state based on the state of the case upper terminals 35a to 35d and the case lower terminals 36a to 36d, This corresponds to an example of “determination means”. Note that the detection unit 7 is omitted, and P1 and P2 input signals are directly input to the control unit 6, and the control unit 6 determines whether the first connection state, the second connection state, or the non-connection depending on the state of these signals. Any one of the states may be determined.

  Next, non-contact communication processing in the mobile terminal 301 configured as described above will be described with reference to FIG. FIG. 6 is a flowchart illustrating the flow of non-contact communication processing performed by the mobile terminal according to the third embodiment.

  First, when the antenna unit 350 is attached to the case 302, it is determined in step S101 whether the antenna unit 350 is in the holding position or the upper surface position. Here, when it is determined Yes in step S101, a transmission / reception setting suitable for performing communication by placing the non-contact communication medium C on the display device 3 side (upper surface side) of the portable terminal 301 is set in step S102. Done. In the screen reading transmission / reception setting process in step S102, the non-contact communication unit 20 sets the output state of the radio wave from the antenna 51 to a low output mode in which the output state is a predetermined low output state based on the signal from the control unit 6. The method for increasing / decreasing the radio wave output can use various known methods. For example, it may be a method of adjusting the amplitude level of the modulated signal, and when the amplified signal is amplified and output. A method of changing the degree of amplification in the amplifier may be used. Further, in the demodulator 23, a reception filter corresponding to the type (for example, IC card) of the non-contact communication medium C that performs communication in the non-contact communication process is selected. In this way, by setting in step S102, the non-contact communication medium C is likely to be tricked closer when the antenna unit 350 is at the upper surface position (for example, the IC card is inserted into the portable terminal 301 at the upper surface position). By setting the output from the antenna 51 to be low in a settlement application such as being on the upper surface side, power can be reduced.

  Next, in step S <b> 103, operation settings suitable for performing communication by placing the non-contact communication medium C on the upper surface side of the portable terminal 301 are performed. In the decoy reading operation setting process in step S103, an operation setting suitable for a case where the non-contact communication medium C is communicated in an application in which the antenna unit 350 is in the upper surface position is easily tampered closer is performed. Specifically, in the case of a payment application in which the IC card is placed on the upper surface side of the mobile terminal 301, the display of the display device 3 is set to a payment screen (a screen on which payment amount or the like can be displayed). In addition, sound settings suitable for settlement use are performed. In this sound setting, for example, sound such as “Take me card” or “Thank you” and payment sound (such as “Chareen”) according to the type of IC card is set to flow according to the processing. Is done. Note that the mobile terminal 301 has a built-in speaker (not shown) for generating the sound. In addition, the key operation unit 4 is set in accordance with, for example, a payment application (the payment key is lit). The settlement screen displayed on the display device 3 corresponds to an example of “first information”. The display device 3 and the speaker correspond to an example of “notification means”.

  On the other hand, if it is determined No in step S101, the non-contact communication medium C may be read at a position some distance away (for example, a moire application in which the mobile terminal 301 itself is brought close to the non-contact communication medium C, etc. Here, for convenience of explanation, transmission / reception settings suitable for “reading” are performed in step S104. In the tear-off transmission / reception setting process in step S104, the non-contact communication unit 20 sets a high output mode in which the output state of the radio wave from the antenna 51 is set to a predetermined high output state based on the signal from the control unit 6. Further, in the demodulator 23, a reception filter corresponding to the type (for example, RFID tag) of the non-contact communication medium C that performs communication in the non-contact communication process is selected. Thus, by setting in step S104, when the antenna unit 350 is at the lower surface position, the output from the antenna 51 is increased in an application where the non-contact communication medium C may be read at a certain distance. It can be set to improve reading performance. The control unit 6 and non-contact communication that can be changed between a high output mode in which the output state of the radio wave from the antenna 51 is a predetermined high output state and a low output mode in which the output state is lower than in the high output mode. The unit 20 corresponds to an example of “output changing unit”.

  Next, in step S105, operation settings suitable for an application (grid reading) in which the non-contact communication medium C may be read at a position some distance away are performed. In the tear-reading operation setting process in step S105, the display on the display device 3 is set to a tear-reading screen (a screen that can display a reading result of a reading object such as a lift ticket or a ticket). In addition, sound settings suitable for the purpose of reading through are performed. In this sound setting, for example, a high tone such as “beep”, a low tone such as “boo”, a beep sound, and an alarm sound flow according to the reading result. Further, the key operation unit 4 is set in accordance with, for example, the reading operation (the reading key is lit). Note that the screen for reading on the screen displayed on the display device 3 corresponds to an example of “second information”.

  Then, when the decoy reading setting or the triangulation reading setting is made in the processes of steps S102 to S105 as described above, a setting confirmation process is performed in step S106. In this process, for example, each setting is confirmed when the user of the mobile terminal 301 operates the key operation unit 4. If the setting confirmation process is performed in step S106, the processes after step S107 are repeated until the holding position of the antenna unit 350 is changed.

  First, in step S107, it is determined whether or not an instruction to read the non-contact communication medium C has been issued. In this step S107, it is determined whether or not a trigger key for reading the non-contact communication medium C has been pressed by the user or the like. Until a reading instruction is given, the determination of No is repeated in step S107.

  If it is determined in step S107 that a reading instruction has been issued (Yes in S107), it is determined in step S108 whether or not the non-contact communication medium C has been detected. In step S108, the determination of No is repeated until the non-contact communication medium C is detected. And if it determines with Yes in step S108, the predetermined process (For example, the process of subtracting the amount of goods from the remaining amount memorize | stored in the IC card etc.) in the non-contact communication medium C will be performed in step S109. In step S110, the control unit 6 performs predetermined data processing. Then, as described above, the processing from step S107 is repeated until the holding position of the antenna unit 350 is changed.

As described above, in the mobile terminal 301 according to the third embodiment, the case upper side terminals 35a to 35d and the case lower side terminals 36a to 36d are provided on the case 302 side, and the antenna unit 350 includes the case upper side. Antenna side terminals 57a to 57d that can be electrically connected to the side terminals 35a to 35d and the case lower side terminals 36a to 36d are provided. When the holding position of the antenna unit 350 becomes the upper surface position, the connection between the antenna side terminals 57a to 57d and the case upper side terminals 35a to 35d is in the first connection state, and the holding position of the antenna unit 350 is the lower surface. When the position is reached, the connection between the antenna side terminals 57a to 57d and the case lower side terminals 36a to 36d is configured to be in the second connection state. In this configuration, the connection state between the terminals when the antenna unit 350 is at the upper surface position is clearly different from the connection state between the terminals when the antenna unit 350 is at the lower surface position, and a separate electrical state corresponding to each is ensured. Can be generated.
Furthermore, based on the state of the case upper side terminals 35a to 35d and the case lower side terminals 36a to 36d, the detection unit 7 and the control unit 6 (which determine whether the state is the first connection state or the second connection state) Determination means) is provided. According to this configuration, it is possible to accurately determine the position of the antenna unit 350 with a simple configuration based on the electrical signal that is clearly distinguished between the upper surface position and the lower surface position.

Further, the control unit 6 and the non-contact that can be changed at least to a high output mode in which the output state of the radio wave from the antenna 51 is a predetermined high output state and a low output mode in which the output state is lower than in the high output mode. A communication unit 20 (output changing means) is provided. The control unit 6 and the non-contact communication unit 20 are set to the low output mode when it is determined in step S101 that they are in the upper surface position (the first connection state), and are in the lower surface position (second connection). If it is determined that the high power mode is selected, the high power mode is set.
In this configuration, the non-contact communication medium C is likely to be trapped closer when the antenna unit 350 is at the upper surface position (for example, settlement such that the IC card is held on the upper surface side of the portable terminal 301 when the antenna unit 350 is at the upper surface position. In the application, etc., the output from the antenna 51 can be set low to reduce the power consumption. On the other hand, when the antenna unit 350 is in the lower surface position, the non-contact communication medium C may be read at a position somewhat distant (for example, the mobile terminal 301 itself is brought closer to the non-contact communication medium C when the antenna unit 350 is in the lower surface position. For example, the output from the antenna 51 can be set higher in the case of use for cutting, etc., and the reading performance can be improved.

  Further, when it is determined in step S101 that the antenna unit 350 is at the upper surface position, the first information corresponding to the upper surface position is notified, and when it is determined that the antenna unit 350 is the lower surface position, the first information corresponding to the lower surface position is notified. (2) A display device 3 for notifying information and a speaker are provided. According to this configuration, the user or the like can easily recognize whether the antenna unit 350 is at the upper surface position or the lower surface position, and the recognized person can easily take a response according to the position of the antenna unit 350. .

[Fourth embodiment]
Next, the portable terminal 401 which concerns on 4th Embodiment of this invention is demonstrated with reference to FIG. As shown in FIG. 7, the fourth embodiment is the same as the first embodiment except that the configuration of the position changing unit that changes the holding position of the antenna unit 450 is different. Hereinafter, other points different from the first embodiment will be mainly described. In addition, the same code | symbol is attached | subjected to the component substantially the same as the said 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 7A is an explanatory view showing a state where the antenna unit is mounted on the upper surface side of the case in the mobile terminal according to the fourth embodiment, and FIG. 7B is an intermediate position of the antenna unit of the case. FIG. 7C is an explanatory diagram illustrating a state in which the antenna unit is mounted on the lower surface side of the case.

  In the first embodiment described above, as the configuration of the position changing means, the protrusions 53a and 53b provided on the antenna unit 50 are replaced with the first engagement parts 31a and 31b and the second engagement parts 32a and 32b provided on the case 2. The antenna unit 50 is attached to the case 2 by being fitted, but in the fourth embodiment, instead of this configuration, a slide mechanism is provided in the portable terminal 401, and the antenna unit 450 is provided by this slide mechanism. The holding position is continuously changed.

  More specifically, as shown in FIG. 7, the front side of the case 402 is formed in a curved shape with chamfered corners. A pair of U-shaped grooves 38 are provided in a region on the front side of the case 402 in the pair of case side wall portions 33 disposed on both sides in the width direction of the case 402. The antenna unit 450 is slidable along the U-shaped groove 38 from the upper surface side (see FIG. 7A) to the lower surface side (see FIG. 7B). Further, on the upper surface position side and the lower surface position side in the vicinity of the U-shaped groove 38, a case upper side terminal 35 and a case lower side terminal 36 having the same configuration as in the third embodiment described above are provided. A case intermediate terminal 37 having the same configuration as the case upper terminal 35 and the case lower terminal 36 is provided at an intermediate position between the upper surface position and the lower surface position in the vertical direction.

  The holding member 452 of the antenna unit 450 includes an antenna fixing portion 54 to which the antenna 51 is fixed, and a pair of mounting portions 455 that can slidably attach the antenna fixing portion 54 to the U-shaped groove 38 of the case 402. Is provided. The pair of attachment portions 455 are provided on one side in the width direction and the other side in the width direction of the antenna fixing portion 54, respectively. Further, the mounting portion 455 is provided with a plurality of antenna-side terminals 57 as in the third embodiment described above.

  As shown in FIG. 7A, the antenna unit 450 configured as described above slides along the U-shaped groove 38 in a state in which the antenna fixing portion 54 is arranged on the upper surface position on the upper side of the case 402. Then, as shown in FIG. 7B, it can be displaced to an intermediate position between the upper surface position and the lower surface position in the vertical direction. Further, when the antenna unit 450 is further slid from the upper surface position shown in FIG. 7A through the intermediate position along the U-shaped groove 38, the antenna unit 450 can be displaced to the lower surface position on the lower side of the case 402. . As described above, the holding position of the antenna unit 450 can be displaced between the upper surface position, the intermediate position, and the lower surface position without removing the antenna unit 450 from the case 402. The U-shaped groove 38 and the attachment portion 455 correspond to an example of a “displacement mechanism”.

As described above, in the fourth embodiment, the antenna unit 450 is positioned at the upper position on the upper side of the case 402, the intermediate position between the upper surface position and the lower surface position in the vertical direction (the intermediate position on the outer side of one end in the longitudinal direction of the case Position), a U-shaped groove 38 and a mounting portion 455 that can be changed are provided at the lower surface position on the lower side of the case 402, respectively.
As described above, in the configuration in which the antenna unit 450 is displaced by the displacement mechanism, there is a low possibility that the antenna unit will be lost, and the management of parts of the antenna unit 450 can also be saved. Furthermore, in the above configuration, the antenna unit 450 can be changed not only in the upper surface position and the lower surface position, but also in the middle thereof, so that the arrangement relationship between the portable terminal 501 and the non-contact communication medium C is more easily communicated. As a result, the mobile terminal 501 can be easily adapted to a wider range of uses.

  Next, the portable terminal 501 which concerns on the 1st modification in 4th Embodiment of this invention is demonstrated with reference to FIG. As shown in FIG. 8, the first modification of the fourth embodiment is the same as the fourth embodiment except that the configuration of the position changing means for changing the holding position of the antenna unit 550 is different. Hereinafter, other differences from the fourth embodiment will be mainly described. In addition, the same code | symbol is attached | subjected to the component substantially the same as the said 4th Embodiment, and the description is abbreviate | omitted.

  FIG. 8A is an explanatory diagram showing a state where the antenna unit is mounted on the upper surface side of the case in the mobile terminal according to the first modification of the fourth embodiment, and FIG. 8B is the antenna unit. FIG. 8C is an explanatory view showing a state where the antenna unit is attached to an intermediate position of the case, and FIG. 8C is an explanatory view showing a state where the antenna unit is attached to the lower surface side of the case.

  In the above-described fourth embodiment, the mobile terminal 401 is provided with a slide mechanism, and the holding position of the antenna unit 450 is continuously changed by the slide mechanism. However, in the first modification, this configuration is replaced. The holding position is continuously changed by rotating the antenna unit 550 around the shaft.

  More specifically, as shown in FIG. 8, the front side of the case 502 is formed in a curved shape with chamfered corners. Further, in the pair of case side wall portions 33 disposed on both sides in the width direction of the case 502, the rotation shaft portions 39 are provided on one side in the width direction and the other side in the width direction of the antenna fixing portion 54. The rotating shaft 39 is pivotally supported by the case side wall 33 on the front side of the case 502.

As shown in (B), it can be displaced to an intermediate position between the upper surface position and the lower surface position in the vertical direction. Further, when the antenna unit 550 is further rotated from the upper surface position shown in FIG. 8A, the antenna unit 550 can be displaced to the lower surface position on the lower side of the case 502 as shown in FIG. 8C. Thus, also in the configuration of the first modification, the same effect as that of the above-described fourth embodiment can be obtained.
