The information processing unit 20 of the payment terminal device 1 includes a CPU (Central Processing Unit) 21 that generally manages the processing of each unit of the payment terminal device 1 shown in FIGS. 1 and 2. In FIG. 2, each unit of the payment terminal device 1 is connected to the CPU 21.

  The local wireless communication unit 22 is connected to the local wireless communication antenna 23, and performs wireless communication by, for example, a wireless LAN (Local Area Network) via a local wireless communication path (not shown). Local wireless communication is not limited to, for example, a wireless LAN, but may be Bluetooth (registered trademark) or the like. The wide area wireless communication unit 24 is connected to the wide area wireless communication antenna 25 and performs wide area wireless communication via a wide area wireless communication path (WAN: Wide Area Network) (not shown). Wide-area wireless communication is, for example, W-CDMA (Wideband Code Multiple Access), UMTS (Universal Mobile Telecommunication Systems), CDMA (Code Division Multiple Access), or CDMA (Code Division Multiple Access) E (LTE) mobile communication. Can do.

  The settlement terminal device 1 of the present embodiment is equipped with two wireless communication units, that is, the local wireless communication unit 22 and the wide area wireless communication unit 24 as a communication function, but either one may be mounted. Alternatively, instead of the wireless communication unit, a wired communication unit such as a wired LAN such as IEEE802.3, a public telephone line, or a dedicated telephone line may be provided.

  The display unit 3B is configured using, for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence), and displays information or data instructed by the CPU 21 to be displayed. The touch input detection unit 3C detects a touch input of a user (for example, a clerk at a registered member store of a credit card or a customer who has purchased a product) on the touch panel display unit 3D.

  A flash ROM (Read Only Memory) 32 stores various data. The stored data may be, for example, business-related data or a program for controlling the operation of the payment terminal device 1 (mainly the information processing unit 20). Further, the program includes various programs related to the operation of the payment terminal device 1 such as an application (software) for payment processing. For this reason, the flash ROM 32 has a function as a recording medium for recording a program.

  A DRAM (Dynamic Random Access Memory) 33 is used for temporarily storing processing data generated in the middle of arithmetic processing associated with the operation of the payment terminal device 1 (mainly the information processing unit 20). Work memory used.

  The keypad unit 34 includes a power switch 3E and a “return” key 3F shown in FIG.

  The magnetic card reader unit 35 is provided on the side of the main body side surface 2J opposite to the main body side surface 2H provided with the lock release button 5A in FIG. 1 together with a slit (not shown) for sliding the magnetic card.

An open state detection switch 2B (see FIG. 2) that is provided on the main body 2 and detects that the lid 3 has been opened (that is, the end opposite to the hinge 3G of the lid 3 is separated from the main body 2). Is also connected to the CPU 21 via the open state detector 42. Accordingly, the CPU 21 receives a signal indicating whether the lid 3 is opened or closed.

  In addition, a power supply unit (not shown) for supplying power to each unit of the settlement terminal device 1 including the information processing unit 20 is provided. A CPU 21, a tamper control unit 36, which will be described later, and an SRAM (Static Random Access Memory) 37 are connected to a backup battery 38. When the supply of power from a power supply unit (not shown) is stopped, the backup battery Power is supplied from 38. The tamper control unit 36 is for ensuring tamper resistance of the settlement terminal device 1. “Tamper resistance” refers to resistance to an unauthorized analysis or modification of software or hardware inside the apparatus, or an unauthorized take, modification, or use of information inside the apparatus. That is, tamper resistance is, for example, the difficulty of analyzing internal structures provided in software or hardware or stored data. By providing tamper resistance, for example, information of a service user (for example, a customer) can be protected and transactions can be performed safely. The information of the service beneficiary is stored in, for example, the SRAM 37, and the tamper control unit 36 deletes the information stored in the SRAM 37 when detecting the unauthorized analysis, modification, attack, information take-off or the sign described above.

The card information read by the non-contact type IC card reader / writer unit or the contact type IC card reader unit is input to the CPU 21.

  FIG. 4 is a control flowchart of the touch panel operation by detecting the open state of the lid 3. The features of the payment terminal device 1 in this embodiment will be described with reference to FIG. 4 and FIGS. 1 to 3 described above.

  In the flowchart of the touch panel operation illustrated in FIG. 4, the information processing unit 20 of the payment terminal device 1 detects whether the lid unit 3 is in the open state or the closed state by the open state detection unit 42 connected to the open state detection switch 2B. (Step S401). When detecting that it is in the “open state”, the information processing unit 20 of the settlement terminal device 1 responds even if a touch on the touch screen of the touch panel display unit 3D is detected by the touch screen (touch input detection unit 3C). The operation is not performed (step S402). As a specific example, the display screen of the touch panel display unit 3D is not changed in response to the touch on the touch screen of the touch panel display unit 3D. That is, the information processing unit 20 of the payment terminal device 1 displays the display screen displayed immediately before touching the touch screen of the touch panel display unit 3D on the touch panel display unit 3D even after touching the touch screen.

  Alternatively, the information processing unit 20 of the payment terminal device 1 displays a display screen different from the display screen immediately before touching the touch screen for a preset period after the touch, and then immediately before touching the touch screen. The display screen may be displayed again. The display screen that is different from the display screen immediately before the touch is, for example, the touched display element (for example, software key) among the display elements constituting the display screen is changed to highlighted display, and the other display is the same as that immediately before the touch. An element may be provided. The display screen of the touch panel display unit 3D returns to the non-emphasized display immediately before the touch after passing through the highlighted display of the touched display element once. Accordingly, the settlement terminal device 1 can more clearly present to the operator that the operation corresponding to the touch input is not performed when the lid 3 is in the opened state.

  As described above, when the lid 3 is opened, the information processing unit 20 of the payment terminal device 1 changes the display screen displayed immediately before touching the touch screen of the touch panel display unit 3D to the touch screen. Even after the touch, is displayed on the touch panel display 3D. When the lid 3 is in a closed state, the display screen of the touch panel display unit 3D transitions in response to a touch on the touch screen of the touch panel display unit 3D. That is, the information processing unit 20 of the payment terminal device 1 displays a display screen different from the display screen immediately before the touch input on the touch panel display unit 3D according to the touch input to the touch screen. Occurrence of processing unintended by the operator is reduced, and the labor, inconvenience, and discomfort of the operator and the customer are reduced.

  For example, when the information processing unit 20 of the payment terminal device 1 is executing the payment process, when trying to print a receipt indicating payment contents, the remaining roll paper 2D for printing the receipt is in a small state. Or jam may occur during printing. The operator of the settlement terminal device 1 changes the roll paper 2D or cancels the jammed state of the drawer 2F by changing the cover 3 from the closed state to the open state. During these operations, the operator may unintentionally touch the touch screen of the large-screen touch panel display unit 3D that occupies a considerable area of the upper surface 3A of the lid 3. In this case, the operator intends that the information processing unit 20 of the payment terminal device 1 is in a state in which an operation corresponding to the touch on the touch screen of the touch panel display unit 3D can be executed (a state in which the display screen can be changed). Processing that does not occur. For example, it is conceivable that the operator erroneously ends the settlement process in the middle. Alternatively, it is conceivable that an operator rewrites or erases input information by mistake. Alternatively, it is conceivable that the display content on the display unit of the touch panel display unit 3D is changed to another display content not intended by the operator and displayed.

  In order to solve this problem, the information processing unit 20 of the payment terminal device 1 according to the first embodiment displays the touch panel display unit 3D immediately before touching the touch screen when the lid unit 3 is opened. The display screen to be displayed is displayed on the touch panel display unit 3D. When the lid 3 is in the closed state, the information processing unit 20 of the settlement terminal device 1 displays a display screen different from the display screen immediately before the touch input according to the touch input to the touch screen 3D. To display. Therefore, the occurrence of processing not intended by the operator is reduced, and the labor, inconvenience, and discomfort of the operator and customer are reduced. The above effects are the same in other business processes using the settlement terminal device 1.

  In step S402, when the lid 3 is in an open state, a number of display screens that are displayed immediately before touching the touch screen of the touch panel display 3D are displayed on the touch panel display 3D. There is a way. In the first method, the payment terminal device (information processing device) does not detect a touch, that is, the detection signal from the touch input detection unit 3C corresponding to the touch on the touch screen of the touch panel display unit 3D is not output. It is. This is realized, for example, when the information processing unit 20 sets the touch screen in the insensitive state or interrupts the supply of operating power to the touch screen. The second method is to treat the payment terminal device (information processing device) as detecting the touch but not detecting it. For example, the detection signal from the touch screen is output, but the information processing unit 20 blocks the input of the detection signal from the touch screen to the CPU 21. Alternatively, the detection signal from the touch screen is input to the CPU 21, but the information processing unit 20 does not sense the input of the detection signal or does not input the operation program corresponding to the detection signal. The third method is that the settlement terminal device (information processing device) does not execute the operation according to the touch input. That is, a detection signal from the touch screen is output and the detection signal is input to the CPU 21, but the information processing unit 20 does not execute the software program corresponding to the touch input to the touch screen. . Whichever method is used, the display screen of the touch panel display unit 3D does not transition to a different display screen in response to a touch on the touch screen of the touch panel display unit 3D when the lid 3 is in an open state. That is, the information processing unit 20 of the payment terminal device 1 displays the display screen displayed immediately before touching the touch screen of the touch panel display unit 3D on the touch panel display unit 3D even after touching the touch screen.

  Furthermore, when the lid 3 is in the open state, the information processing unit 20 of the payment terminal device 1 may turn off the display on the touch panel display unit 3D (step S403). That is, the information processing unit 20 of the payment terminal device 1 may hide the display screen of the touch panel display unit 3D when the lid unit 3 is in the opened state. The information processing unit 20 of the settlement terminal device 1 turns off the backlight (not shown) or turns off the display screen signal output to the touch panel display unit 3D in order to hide the display screen of the touch panel display unit 3D. To.

  The operator of the store where the payment terminal device 1 is installed looks at the touch panel display unit 3D from the drawer 2F side of the roll paper 2D and operates the payment terminal device 1. During the operation, if the lid 3 is changed from the closed state to the open state, the content displayed on the touch panel display unit 3D may be seen by a third party other than the operator. Among the contents displayed on the touch panel display unit 3D, there is information that is not desired to be seen by a third party, such as customer card information, personal identification number, store secret information, and operator personal information. If the information processing unit 20 of the payment terminal device 1 turns off the display on the touch panel display unit 3D when the lid 3 is in the open state, such information that is not desired to be seen by a third party is not displayed. Therefore, information of a service recipient (for example, a customer) in transaction and business processing is protected.

  The information processing unit 20 of the payment terminal device 1 repeats steps S401 to S403 described above while the lid 3 is in the open state. At this time, if the power switch 3E or the “return” key 3F is pressed, the information processing unit 20 of the settlement terminal device 1 enables an operation corresponding to the touch input to the touch screen of the touch panel display unit 3D. Good. Alternatively, the information processing unit 20 of the payment terminal device 1 may perform display on the touch panel display unit 3D. When the lid 3 is in the open state, when the operator needs some operation or confirmation of the display on the payment terminal device 1 (for example, escape from the operation error or confirmation of the operation error), the information processing unit 20 enables the operation or display. Accordingly, the settlement terminal device 1 becomes easier to use.

  When the closed state of the lid 3 is detected in step S401, the information processing unit 20 of the settlement terminal device 1 detects the touch on the touch screen of the touch panel display unit 3D by the touch input detection unit 3C, and receives the touch input. The corresponding operation is performed (step S404). At the same time, the information processing unit 20 of the payment terminal device 1 performs display on the touch panel display unit 3D (step S405).

  As described above, according to the settlement terminal device of the present embodiment, when the lid 3 is in the open state, occurrence of processing unintended by the operator in settlement or other business processing is reduced, and the operator and Customer trouble, inconvenience, and discomfort are alleviated, and information of service recipients (eg, customers) in transaction and business processing is protected. That is, the possibility that the payment process unintended by the operator is executed or the payment process unintentionally canceled is reduced. Therefore, an operator (for example, a store clerk) of the information processing apparatus does not have to receive the card from the customer again and make another payment from the beginning.

  As mentioned above, although various embodiment was described with reference to drawings, it cannot be overemphasized that this indication is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present disclosure. Understood. The information processing apparatus and payment terminal apparatus of the present invention are not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
