Determine if it exists outside. In this case, the communication capability determination unit 141 determines whether or not the radio communication antenna 103 is within the communicable range RC by determining whether or not sufficient electromagnetic waves for performing radio communication have arrived from the close proximity wireless antenna sheet 3. Determine. Here, whether or not the wireless communication antenna 103 is within the communicable range RC is switched depending on the angle or the like at which the terminal device 1 is held by the terminal stand 2. This will be described in detail in the section [Changes in communication availability based on tilt angle]. Then, the communicability determining unit 141 supplies the display control unit 142 with a determination result as to whether or not the wireless communication antenna 103 is within the communicable range RC.

  The display control unit 142 displays a predetermined screen on the display 101 based on the display information received from the server 6 via the wireless communication antenna 103. Specifically, when the wireless communication antenna 103 is within the communicable range RC, the display control unit 142 displays a personal information input screen on the display 101 based on the display information received from the server 6. Then, when the wireless communication antenna 103 is out of the communicable range RC, the display control unit 142 displays a display screen (“ "Peep prevention screen") is displayed on the display 101.

(Stand for terminal)
Next, the terminal stand (installation stand) 2 will be described. FIG. 4 is a side view of the terminal stand 2. As shown in FIG. 4, the terminal stand 2 includes a terminal holding unit 20, a substantially disk-shaped base unit 21, first to third arms 22 </ b> A to 22 </ b> C, first and second rotation support units 23 </ b> A, 23B.

  The terminal holding unit 20 supports the terminal device 1 from the back surface and the bottom surface when the terminal device 1 is placed. The first arm 22A extends substantially vertically from the base portion 21, and a first rotation support portion 23A is provided at the extended end portion. 23 A of 1st rotation support parts support the 2nd arm 22B so that rotation in the direction which an arrow shows is possible. A second rotation support portion 23B is provided at the end of the second arm 22B on the side not supported by the first rotation support portion 23A. The second rotation support part 23B supports the third arm 22C so as to be rotatable in the direction indicated by the arrow. The third arm 22 </ b> C is connected to the terminal holding unit 20 substantially vertically.

  As described above, the terminal stand 2 is configured such that the angle of the second arm 22B with respect to the first arm 22A at the first rotation support portion 23A and the third arm 22C with respect to the second arm 22B at the second rotation support portion 23B. Each angle is configured to be adjustable. Thereby, the terminal stand 2 can change the angle and height of the terminal holding part 20. This will be described with reference to FIG.

  FIG. 5A shows the terminal stand 2 when the angle formed by the terminal holding unit 20 with respect to the base portion 21 (also simply referred to as “inclination angle θ”) is set, and FIG. The terminal stand 2 when the inclination angle θ is set small is shown.

  As shown in FIG. 5A, when the first arm 22A and the second arm 22B are substantially on the same straight line and the third arm 22C is substantially perpendicular to the second arm 22B, the inclination angle θ is growing. On the other hand, when the second arm 22B is rotated clockwise with respect to the first arm 22A from the state of FIG. 5A, the terminal stand 2 is in the state of FIG. Get smaller. When the second arm 22B is further rotated clockwise and the third arm 22C is rotated counterclockwise from the state of FIG. 5B, the terminal holding unit 20 increases the inclination angle θ. The height with respect to the base part 21 becomes low with keeping. Thus, the terminal stand 2 can suitably change the inclination angle θ and the height of the terminal device 1 with respect to the base portion 21 while holding the terminal device 1.

(server)
Next, the server 6 will be described. The server 6 includes, as hardware, a communication device capable of data communication, a processor such as a CPU, and a memory such as a ROM and a RAM. FIG. 6 is a functional block diagram of the server 6. As shown in FIG. 6, the server 6 is functionally composed of a communication unit 62, a storage unit 63, a processing unit 64, and the like.

The storage unit 63 includes a memory such as a ROM or a RAM, and stores display information of each screen to be displayed on the terminal device 1. The storage unit 63 stores the input information on the personal information input screen transmitted from the terminal device 1 based on the control of the processing unit 64.

  The processing unit 64 includes a transmission control unit 641 and a storage control unit 642. The transmission control unit 641 transmits display information of each screen such as a personal information input screen to the terminal device 1 through the communication unit 62 in response to a request from the terminal device 1. The storage control unit 642 causes the storage unit 63 to store the input information when the communication unit 62 receives the input information input on the personal information input screen.

[Change in communication availability based on tilt angle]
Next, a change in availability of communication of the wireless communication antenna 103 based on a change in the tilt angle θ will be described with reference to FIGS. In general, the wireless communication antenna 103 is outside the communicable range RC when the display 101 is easily viewed by others, and the wireless communication antenna 103 is displayed when the display 101 is not easily viewed by others. 103 is within the communicable range RC.

  FIG. 7 shows the terminal stand 2 that holds the terminal device 1 with the inclination angle θ set large. FIG. 8 shows the terminal stand 2 that holds the terminal device 1 with the inclination angle θ set to be small. 7 and 8 show the communicable range RC.

  The communicable range RC shown in FIG. 7 and FIG. 8 is formed in the vicinity of the close proximity wireless antenna sheet 3, and the wireless communication antenna 103 is within the communicable range RC or outside the communicable range RC depending on the inclination angle θ. Exists in range. For example, the communicable range RC is a range in which the wireless communication antenna 103 is outside the communicable range RC when the tilt angle θ is equal to or greater than a predetermined angle (also referred to as “angle θth”). Here, the angle θth described above is such that the tilt angle θ is equal to or greater than the angle θth when the display 101 is easily peeped by a person other than the input person, and the tilt angle θ is less than the angle θth when the display 101 is difficult to peep. Is set to be In this case, adjustment of the communicable range RC by adjusting the output of the close proximity wireless antenna sheet 3, adjustment of the installation position of the terminal stand 2, and the terminal device 1 are performed by the terminal holding unit 20 so that the above-described condition regarding the angle θth is satisfied. Adjustment of the height held by the is performed.

  In the example of FIG. 7, the terminal device 1 is held in a state of being nearly perpendicular to the close proximity wireless antenna sheet 3 and is in a state in which the display screen of the display 101 is easily peeped by a person other than the input person. In this case, the inclination angle θ is equal to or greater than the angle θth, and the wireless communication antenna 103 exists outside the communicable range RC. Therefore, in this case, since the communication capability determination unit 141 of the terminal device 1 does not reach the radio communication antenna 103 with sufficient electromagnetic waves necessary for communication, the radio communication antenna 103 exists outside the communicable range RC. Is determined. Then, the display control unit 142 of the terminal device 1 displays a peep prevention screen on the display 101 as described later.

  On the other hand, in the example of FIG. 8, the terminal device 1 is held in a nearly horizontal state, and it is difficult for a person other than the operator to look into the display screen of the display 101. In this case, the inclination angle θ is less than the angle θth, and the wireless communication antenna 103 is within the communicable range RC. In this case, the communication capability determination unit 141 of the terminal device 1 determines that the radio communication antenna 103 exists within the communicable range RC because sufficient electromagnetic waves necessary for communication have reached the radio communication antenna 103. To do. The display control unit 142 displays a personal information input screen on the display 101 as will be described later.

[Switch display screen]
Next, the display screen switching control of the display 101 executed by the display control unit 142 will be described.

(1) Initial Screen FIG. 9 is a front view of the terminal device 1 that displays a screen (also referred to as “initial screen”) that is displayed when the terminal device 1 is not operated. As shown in FIG. 9, in the initial state, the display control means 142 displays an advertisement screen indicating that the application for the point card is accepted regardless of whether the wireless communication antenna 103 is outside the communicable range RC or within the communicable range RC. Is displayed on the display 101 as an initial screen. In this case, the inclination angle θ is preferably set to be equal to or larger than the angle θth. Thereby, the terminal device 1 can display in a mode that it is easy for a passer-by to see that the point card is accepted. When the display control unit 142 displays the initial screen on the display 101, the display control unit 142 may acquire the display information from the storage unit 13 in which the display information of the initial screen is stored in advance. Display information may be received.

(2) Personal Information Input Screen FIG. 10 shows a front view of the terminal device 1 on which the personal information input screen is displayed. The display control unit 142 switches the display of the display 101 from the initial screen to the personal information input screen when detecting a predetermined operation such as pressing the touch panel 105 in the state where the initial screen shown in FIG. 9 is displayed. When the display control unit 142 displays the personal information input screen on the display 101, the display control unit 142 may acquire the display information from the storage unit 13 that stores the display information of the personal information input screen in advance, and the switching timing described above. Display information may be received from the server 6.

  The personal information input screen shown in FIG. 10 includes a range mark 41 indicating that the wireless communication antenna 103 is within the communicable range RC, input fields 42 to 44 for inputting personal information, and a cancel button. 45 and a registration button 46 are displayed.

  As described above, when the personal information input screen in which the wireless communication antenna 103 is within the communicable range RC is displayed, the display control unit 142 displays the area mark 41 indicating that the radio communication antenna 103 is within the communicable range RC on the upper right side of the screen. Thereby, the display control means 142 makes an operator visually recognize suitably that the terminal device 1 is a communicable state.

  In addition, when the input fields 42 to 44 are selected by operating the touch panel 105 with a fingertip or a stylus, the display control unit 142 displays a software keyboard or the like and accepts an input to the selected input field. In FIG. 10, the operator has already input “Dainippon” in the input field 42 and “Taro” in the input field 43. Then, the display control unit 142 causes the storage unit 13 to store input information generated by input to the input fields 42 to 44.

  When the cancel button 45 is selected, the display control unit 142 discards the input information indicating the input to the input fields 42 to 44 and cancels the point card application procedure. In this case, the display control means 142 transmits information to the effect that the point card application procedure is canceled to the server 6. On the other hand, when the registration button 46 is selected, the display control unit 142 transmits the input information indicating the input to the input fields 42 to 44 to the server 6 and completes the point card application.

  Here, after the transition from the initial screen to the personal information input screen, the communicable determination unit 141 continues to determine whether or not the wireless communication antenna 103 is within the communicable range RC. Then, the display control unit 142 displays the personal information input screen shown in FIG. 10 on the display 101 only when the wireless communication antenna 103 exists within the communicable range RC. In this case, as shown in FIG. 8, since the inclination angle θ is less than the angle θth, the terminal device 1 is held by the terminal stand 2 in a state where the display 101 is difficult to look into. Accordingly, the display control unit 142 can safely display the personal information input screen and accept input only under a situation where it is difficult for others to look into the display 101.

(3) Peep Prevention Screen FIG. 11 shows a front view of the terminal device 1 on which the peep prevention screen is displayed. When the communication control unit 141 determines that the wireless communication antenna 103 is outside the communicable range RC, the display control unit 142 displays the peep prevention screen shown in FIG. For example, the display control unit 142 displays the peeping prevention screen shown in FIG. 11 on the display 101 based on the display information stored in the storage unit 13 in advance.

  As shown in FIG. 11, the display control unit 142 causes the display 101 to display a warning message for peeping prevention on the peeping prevention screen. Thereby, the display control means 142 urges the user to perform an operation of tilting the terminal device 1 to lie down and reducing the tilt angle θ.

  Further, the display control unit 142 displays an out-of-service mark 47 indicating that the wireless communication antenna 103 is outside the communicable range RC on the upper right side of the screen. Thereby, the display control means 142 makes an operator visually recognize suitably that the terminal device 1 is not in the state which can communicate.

  Further, the display control unit 142 causes the display 101 to display a button 48 for canceling the application. When the application stop button 48 is selected, the display control unit 142 cancels the point card application procedure by discarding the input contents on the personal information input screen. In this case, the display control unit 142 transmits information indicating that the point card application procedure is canceled to the server 6 when the wireless communication antenna 103 is next within the communicable range RC.

  As described above, when the wireless communication antenna 103 is outside the communicable range RC, the display control unit 142 may cause the tilt angle θ to be equal to or greater than the angle θth and cause the display 101 to be peeped by others. , Do not display the personal information input screen. Thereby, the display control means 142 can prevent an operator's input content being seen by others, and can protect operator's information suitably.

[Processing flow]
Next, a processing flow executed by the terminal device 1 will be described. FIG. 12 is a flowchart illustrating a processing procedure executed by the terminal device 1. The terminal device 1 executes the processing flow shown in FIG. 12 when, for example, a predetermined operation is detected while the initial screen shown in FIG. 9 is displayed.

  First, when a predetermined operation is detected while the initial screen shown in FIG. 9 is being displayed, the display control unit 142 of the terminal device 1 displays a personal information input screen and accepts input (step S101). Specifically, in this case, the display control unit 142 causes the display 101 to display a personal information input screen including input fields 42 to 44 necessary for application for the point card shown in FIG. Further, the display control unit 142 causes the storage unit 13 to store the input information input in the input fields 42 to 44 in association with the entry fields 42 to 44.

  Next, the display control means 142 determines whether or not the registration button 46 on the personal information input screen has been selected (step S102). When the registration button 46 is selected (step S102; Yes), the display control unit 142 transmits the input information input in the input fields 42 to 44 to the server 6 (step S103). Then, the storage control unit 642 of the server 6 causes the storage unit 63 to store the input information received by the communication unit 62. Thereafter, the display control unit 142 of the terminal device 1 displays, for example, an initial screen shown in FIG.

  On the other hand, when the registration button 46 is not selected (step S102; No), the display control unit 142 determines whether or not the cancel button 45 is selected (step S104). When the cancel button 45 is selected (step S104; Yes), the display control unit 142 notifies the server 6 that the cancellation has been made and deletes the input information stored in the storage unit 13 (step S105). ). Thereafter, the display control unit 142 of the terminal device 1 displays, for example, an initial screen shown in FIG.

  On the other hand, when the cancel button 45 is not selected (step S104; No), the communication possible determination unit 141 determines whether or not the wireless communication antenna 103 of the terminal device 1 exists outside the communicable range RC ( Step S106). Specifically, the communication possibility determination unit 141 determines whether or not sufficient electromagnetic waves for communication reach the wireless communication antenna 103 from the close proximity wireless antenna sheet 3. When the wireless communication antenna 103 is present within the communicable range RC (step S106; No), the display control unit 142 continues to display the personal information input screen reflecting the input information input so far. The input to the input fields 42 to 44 is accepted (step S110).

  On the other hand, when the wireless communication antenna 103 exists outside the communicable range RC (step S106; Yes), the display control unit 142 displays the peep prevention screen shown in FIG. 11 on the display 101 (step S107). As a result, the display control unit 142 suppresses peeping of the input content on the personal information input screen and prompts the user to change the inclination angle θ of the terminal device 1.

  Next, the display control unit 142 determines whether or not the application stop button 48 has been selected (step S108). When the application stop button 48 is selected (step S108; Yes), the processing means 14 notifies the server 6 that the application has been canceled when the wireless communication antenna 103 is within the communicable range RC. Then, the input information relating to the canceled application is deleted from the storage means 13 (step S109). In this case, the storage control unit 642 of the server 6 deletes the input information from the storage unit 63 when the input information received from the terminal device 1 already exists for the canceled application.

  On the other hand, when the application stop button 48 has not been selected (step S108; No), the communicable determination unit 141 determines whether or not the wireless communication antenna 103 of the terminal device 1 exists outside the communicable range RC ( Step S106). When the wireless communication antenna 103 is within the communicable range RC (step S106; No), the display control unit 142 displays a personal information input screen that reflects the input information stored in the storage unit 13 and performs input. The input to the columns 42 to 44 is accepted (step S110). That is, the display control unit 142 redisplays the personal information input screen immediately before switching to the peep prevention screen in step S107 based on the input information stored in the storage unit 13. In this case, the user does not need to input the contents entered before switching to the peep prevention screen on the personal information input screen again.

[Operational effects of the application system of this embodiment]
According to the application system of the present embodiment, the terminal device 1 is held by the terminal stand 2 on the close proximity wireless antenna sheet 3 and displays a personal information input screen outside the communicable range RC of the close proximity wireless antenna sheet 3. Without displaying a peep prevention screen. Thereby, the terminal device 1 can suppress displaying the input information at a position that can be seen by others, and can suitably protect the information of the input person.

  Further, when the inclination angle θ at which the display of the terminal device 1 is difficult to be seen by a person other than the input person is less than the angle θth, the wireless communication antenna 103 is within the communicable range RC of the close proximity wireless antenna sheet 3. On the other hand, when the inclination angle θ at which the display of the terminal device 1 is easily seen by a person other than the input person is equal to or larger than the angle θth, the wireless communication antenna 103 is outside the communicable range RC of the close proximity wireless antenna sheet 3. Thereby, when the display of the terminal device 1 is easy to be seen by persons other than the input person, the application system can suitably limit the display of the input information and can suitably protect the information of the input person.

  Further, when the wireless communication antenna 103 is within the communicable range RC, the display control means 142 of the terminal device 1 displays the in-range mark 41 indicating that the radio communication antenna 103 is within the communicable range RC on the display 101, thereby performing wireless communication. When the antenna 103 is outside the communicable range RC, an out-of-service mark 47 indicating that the antenna 103 exists outside the communicable range RC is displayed on the display 101. By this aspect, the terminal device can make a user recognize suitably whether it exists in the communicable range RC.

[Modification]
Next, a modification of this embodiment will be described. The following modifications may be applied in any combination to the above-described embodiment.

(Modification 1)
The server 6 transmits display information of a peep prevention screen to be displayed when the terminal device 1 is out of the communicable range RC to the terminal device 1 in advance when the terminal device 1 exists in the communicable range RC. May be. Thereby, the server 6 suitably displays an advertisement or the like to be notified to the user when the terminal device 1 is outside the communicable range RC and is easily peeped.

  FIG. 13 is a front view of the terminal device 1 on which a peep prevention screen is displayed when the terminal device 1 is outside the communicable range RC. In the peep prevention screen shown in FIG. 13, in addition to the out-of-service mark 47, privilege information by admission that is an advertisement related to a point card is displayed. In this case, when the terminal device 1 is within the communicable range RC, the terminal device 1 receives display information of the peep prevention screen from the server 6 in advance. For example, the terminal device 1 may receive the display information of the peep prevention screen shown in FIG. 13 together with the display information of the initial screen from the server 6 and prevent the peep when the transition is made from the initial screen to the personal information input screen. Screen display information may be received from the server 6. In this case, the storage unit 63 of the server 6 stores the display information of the peep prevention screen shown in FIG. 13 in advance, and the transmission control unit 641 displays the peep prevention screen on the request of the terminal device 1. The display information is transmitted to the communication means 62.

  By doing in this way, when the terminal device 1 is in a state where the terminal device 1 is easily peeped, the server 6 positively displays the point card advertisement on the terminal device 1, and the operator and a passerby behind the operator. Can be admitted to a point card.

(Modification 2)
The display control unit 142 of the terminal device 1 may cause the display 101 to display a screen in which the display of the personal information input screen is partially changed as a peeping prevention screen displayed when the wireless communication antenna 103 is outside the communicable range RC. Good. This will be described with reference to FIG.

  FIG. 14 is a front view of the terminal device 1 on which the peep prevention screen in the present modification is displayed. In FIG. 14, the display control unit 142 fills and displays the input fields 42 to 44 displayed on the personal information input screen shown in FIG. In addition, the display control unit 142 displays the out-of-service mark 47 and the application stop button 48 as in the peep prevention screen shown in FIG.

  As described above, in this modification, the display control unit 142 inputs the input fields 42 to 44 while maintaining the display of the personal information input screen in principle when the wireless communication antenna 103 is outside the communicable range RC. Is displayed in an invisible manner. Even in this case, personal information can be suitably prevented from being peeped.

  In place of the display example shown in FIG. 14, the display control means 142 displays only the input fields 42 and 43 that have already been input on the personal information input screen in a manner that the input content cannot be visually recognized. The input field 44 that has not been made may be displayed as in FIG.

(Modification 3)
In the flowchart of FIG. 12, the display control unit 142 switches from the initial screen to the personal information input screen in step S101, and then displays the peep prevention screen in the case of outside the communicable range RC in step S106.

  Instead, for example, when the display control unit 142 determines that the wireless communication antenna 103 exists outside the communicable range RC immediately before switching from the initial screen to the personal information input screen, the personal information input is performed. The peep prevention screen may be displayed without displaying the screen.

  In another example, if no input is made in the input fields 42 to 44, the display control unit 142 continues to display the personal information input screen regardless of whether the communication is within the communicable range RC or outside the communicable range RC. May be. In this case, the display control means 142 determines whether or not the wireless communication antenna 103 exists outside the communicable range RC when detecting the input to the input fields 42 to 44, and out of the communicable range RC. If the screen is present, a peep prevention screen is displayed on the display 101.

  Even in these cases, the display control unit 142 can preferably suppress peeping of the input content on the personal information input screen.

(Modification 4)
The storage unit 13 of the terminal device 1 may store in advance each display information of the initial screen, the personal information input screen, and the peep prevention screen. In this case, the display control unit 142 of the terminal device 1 displays the above-described initial screen, personal information input screen, and peep prevention screen based on the display information stored in the storage unit 13 without communicating with the server 6. It is displayed on the means 16.

(Modification 5)
The input operation to the terminal device 1 is not limited to the operation to the touch panel 105, and may be a mouse click operation when the terminal device 1 has a mouse.

(Modification 6)
In the personal information input screen shown in FIG. 10, input fields 42 to 44 for inputting personal information such as the name of the input person are provided. However, the input screen to which the present invention can be applied is not limited to this, and input other than personal information may be accepted. Even in this case, the terminal device 1 preferably displays the input screen only when the wireless communication antenna 103 is within the communicable range RC, so that the input content is preferably peeped by others. Can be suppressed.
