  However, in the conventional transaction terminal devices including Patent Documents 1 and 2, it has been difficult to prevent erroneous operation of software keys that are important for the operator such as the above-described sales registration key and confirmation completion key. For example, if a software key having such an important meaning in transactions is easily misoperated, it will be inconvenient for both the member store and the customer in terms of the safe execution of the transaction.

  In other words, there is a possibility that an erroneous operation can be easily induced by performing an operation having an important meaning in transactions with a software key. For example, in the case of a physical key (for example, a button) instead of a software key, the operator needs to perform a two-step action of touching the physical key with a finger and then pressing the physical key. It was relatively easy to be aware that the physical key was pressed when performing an operation having an important meaning in transactions.

  However, in a transaction terminal device equipped with a touch panel, the software key displayed on the screen is simply touched by the operator's finger etc., and the software key is pressed as in the two-step operation on the physical key. Therefore, there is a possibility that the operator may easily perform an erroneous operation on a software key having an important transaction meaning (hereinafter referred to as “important key”).

  In view of the above-described conventional situation, the present invention makes it easy for the operator to clearly recognize the execution of an input operation having a transactionally important meaning through a predetermined input operation on the touch panel. It aims at providing the transaction terminal device which suppresses induction.

  The present invention provides a touch panel that displays various screens related to payment processing, an input operation detection unit that detects an input operation on the screen displayed on the touch panel, and the touch panel when no input operation is detected for a predetermined time or more. A mode control unit that shifts the display to a dark display; and after the transition to the dark display, when the input operation detection unit detects the input operation and the dark display is canceled, the dark display is switched to the dark display. It is a transaction terminal device provided with the screen switching judgment part which judges the necessity of switching of the screen displayed on the said touch panel according to the kind of screen currently displayed on the said touch panel immediately before transfer.

  In this configuration, the transaction terminal device detects an input operation on the screen when any screen related to the payment process is displayed on the touch panel, but if the input operation is not detected over a certain time on the screen, The touch panel is shifted to a dark display (for example, sleep mode). Further, the transaction terminal device shifts to a dark display (for example, sleep mode) when the dark display (for example, sleep mode) is canceled after an input operation is detected after the transition to the dark display (for example, sleep mode). Whether or not it is necessary to switch the screen displayed on the touch panel is determined according to the type of the screen displayed on the touch panel immediately before.

  As a result, the transaction terminal device pays attention to the fact that the type of the screen displayed immediately before the transition to the dark display (for example, sleep mode) differs depending on whether the operator has performed an input operation based on his / her own judgment or consciousness. For example, when canceling the dark display (for example, sleep mode) on the touch panel, the dark display (for example, sleep mode) is displayed according to the type (type) of the screen displayed immediately before the transition to the dark display (for example, sleep mode). Since the screen after the release of) is switched, display of a screen unintended by the operator can be suppressed, and the convenience of the input operation for the operator can be improved.

  Further, according to the present invention, a predetermined hierarchical relationship is assigned to the various screens displayed on the touch panel, and the screen switching determination unit displays the screen displayed on the touch panel immediately before the transition to the dark display. When the screen is assigned to a higher hierarchy than the predetermined hierarchy defined in the predetermined hierarchy relationship, the screen displayed on the touch panel immediately before the transition to the dark display is switched to the predetermined screen. It is a transaction terminal device displayed on the touch panel.

  In this configuration, the transaction terminal device is a screen in which the screen displayed on the touch panel immediately before the transition to the dark display (for example, sleep mode) is assigned to a higher hierarchy than the predetermined hierarchy defined in the predetermined hierarchy relationship. In some cases, the screen displayed on the touch panel immediately before shifting to a dark display (for example, sleep mode) is switched to a predetermined screen and displayed on the display unit of the touch panel.

  Thereby, the transaction terminal device, for example, when a screen assigned to a hierarchy higher than a predetermined hierarchy (for example, menu, the same applies below) is displayed immediately before the transition to a dark display (for example, sleep mode), Focusing on the fact that there is a high possibility that the operator has specifically selected or searched for the processing intended, the screen displayed on the touch panel after the dark display (for example, sleep mode) is canceled By switching to the screen, it is possible to easily select a process desired by the operator.

  In the present invention, the screen switching determination unit may be configured such that the screen displayed on the touch panel immediately before the transition to the dark display is a screen assigned from the predetermined hierarchy to a lower hierarchy. It is a transaction terminal device which continues the display of the screen currently displayed on the said touch panel immediately before transfer to a dark display.

  In this configuration, the transaction terminal device displays a dark display (for example, when the screen displayed on the touch panel immediately before the transition to the dark display (for example, sleep mode) is a screen assigned to a lower layer than the predetermined layer (for example, The display of the screen displayed on the touch panel immediately before the transition to the sleep mode is continued.

  Thereby, the transaction terminal device, for example, when the screen assigned to the lower hierarchy than the predetermined hierarchy is displayed immediately before the transition to the dark display (for example, sleep mode), for example, the operator is either Focusing on the high possibility that the purpose was to execute this processing, the screen to be displayed on the touch panel after the dark display (for example, sleep mode) is canceled immediately before the transition to the dark display (for example, sleep mode) By continuing the display with the displayed screen, the processing desired by the operator can be quickly executed.

  In the present invention, the various screens are a plurality of screens related to payment processing, and the predetermined screen is displayed on the touch panel immediately before the transition to the dark display among the plurality of screens related to the payment processing. This is a transaction terminal device that is a screen assigned to a higher hierarchy than the hierarchy corresponding to the previously displayed screen.

  According to this configuration, the predetermined screen is assigned to a layer higher than the layer corresponding to the screen displayed on the touch panel immediately before the transition to the dark display (for example, sleep mode) among the plurality of screens related to the payment process. Therefore, the transaction terminal device can easily select a process or menu desired by the operator as a screen to be displayed on the touch panel after the dark display (for example, sleep mode) is canceled.

  Further, the present invention is the transaction terminal device, wherein the predetermined screen is a screen assigned in advance to any one of the predetermined hierarchical relationships that is designated in advance according to a predetermined input operation.

  According to this configuration, since the predetermined screen is a screen assigned to any one of the predetermined hierarchical relationships specified in advance according to a predetermined input operation, the transaction terminal device displays a dark display (for example, As the screen to be displayed on the touch panel after the sleep mode is released, a screen assigned to a hierarchy corresponding to a predetermined input operation (for example, an instruction from the acquirer or payment processor) is displayed, so that the operator is lost in the operation. Alternatively, by displaying a menu serving as a starting point when troubled, the convenience for the operation of the operator can be improved.

  In the transaction terminal device according to the present invention, the predetermined screen is a screen assigned to a higher hierarchy than the predetermined hierarchy, wherein the display frequency on the touch panel is a predetermined value or more as a screen related to the settlement process. is there.

  According to this configuration, since the predetermined screen is a screen having a display frequency on the touch panel that is equal to or higher than a predetermined value as a screen related to the payment process, the transaction terminal device displays a dark display. Displaying a process or menu frequently used by the operator as a screen to be displayed on the touch panel after (e.g. sleep mode) is released, thereby giving the operator a sense of security and improving convenience. Can do.

  According to the present invention, through a predetermined input operation on the touch panel, it is possible to clearly make the operator aware of the execution of an input operation having an important transaction meaning, and to suppress the induction of an erroneous operation. .

  Further, according to the present invention, when at least a screen related to payment processing is displayed, even when a state where there is no input operation from the operator continues for a predetermined time or longer, the transition to the sleep mode is avoided. It is possible to complete transaction settlement processing quickly.

  Further, according to the present invention, when the sleep mode of the touch panel is released, it is possible to suppress display of a screen that is not intended by the operator, and it is possible to improve the convenience of input operation for the operator.

  In addition, according to the present invention, the total amount of current flowing into the power supply unit accommodated in the housing is reduced by temporarily suppressing or stopping some functions or processes while the printer is operating. Power consumption can be suppressed.

  Next, operation | movement of the payment terminal device 1 of this embodiment is demonstrated with reference to FIG. FIG. 3 is a flowchart for explaining a payment processing procedure of the payment terminal device 1 according to the first embodiment. In FIG. 3, for example, a case where a payment process is performed using a magnetic credit card held by a customer will be described.

  In FIG. 3, first, the CPU 21 displays a prompt (screen) for prompting the operator to read the magnetic card to start the payment processing application on the display unit 3B of the touch panel 3D (S1). . When a store clerk of a member store (for example, a store) performs a reading operation of a magnetic credit card held by a customer, the magnetic card reader unit 35 reads information recorded on the magnetic credit card. When the CPU 21 receives the information read by the magnetic card reader unit 35, the CPU 21 causes the display unit 3B of the touch panel 3D to display a transaction content input screen (see, for example, FIG. 5) that is a target of the payment processing in the payment processing application.

  Thereafter, the store clerk performs an operation of inputting information related to the transaction content to be processed for settlement on the touch panel 3D while confirming with the customer. The CPU 21 detects these input operations via the touch input detection unit 3C.

  For example, a card brand of a magnetic credit card is selected by an input operation of an operator (for example, a store clerk), and information regarding the selected card brand is input to the CPU 21 (S2). Subsequently, a payment amount is input by an input operation of an operator (for example, a store clerk), and information regarding the input payment amount is input to the CPU 21 (S3). Further, a payment method (for example, one-time payment, installment payment, etc.) is selected, the number of payments is input, and information regarding the selected payment method and the input number of payments is input to the CPU 21 (S4).

  When information such as the payment method is input, the customer inputs his / her own signature in the signature input area (not shown) of the signature PAD displayed on the display unit 3B of the touch panel 3D. CPU21 acquires the information regarding the signature input via the touch input detection part 3C (S5).

  Thereafter, the customer performs an operation for finally confirming the input content regarding the transaction content to be processed for settlement on the touch panel 3D, and a predetermined input operation indicating that the input content has been confirmed (details will be described later). I do. The CPU 21 communicates with the local wireless communication unit 22 or the wide area wireless communication unit 24 according to a predetermined operation indicating that the customer has confirmed the input content, and is input to the acquirer or the settlement processor (not shown). A settlement processing request including all input contents (for example, card information, settlement amount, payment method, number of payments) is transmitted (S6).

  When credit is given from an acquirer or a payment processor as an example of a payment destination apparatus and a determination result for permitting transaction contents is transmitted to the payment terminal apparatus 1, the CPU 21 confirms the transaction contents to be the object of payment processing. The result is displayed on the display unit 3B of the touch panel 3D (S7). Further, the CPU 21 causes the printer module 4 to print the confirmation result of the transaction content that is the object of the settlement process as a receipt (S8). Thereby, the process of the payment terminal device 1 is complete | finished. Note that the part in which the CPU 21 performs a series of processing related to the payment processing shown in FIG. 3 in accordance with the payment processing application program stored in the flash ROM 32 corresponds to the payment processing unit of the transaction terminal device according to the present invention.

  FIG. 4 is a flowchart for explaining a determination procedure for determining whether or not a predetermined input operation indicating that the customer has confirmed the input content regarding the transaction content in step S6 shown in FIG. 3 has been performed. Each process of the flowchart shown in FIG. 4 is performed, for example, in step S6 shown in FIG.

  In FIG. 4, the CPU 21 detects an input operation (touch input) by the operator in the touch input detection unit 3C of the touch panel 3D (S11). The CPU 21 determines that the touch input detected by the touch input detection unit 3C is a predetermined important key input acceptance icon 61 (see FIG. 5) as an example of a specific target on the transaction content input screen that is the target of the payment processing of the payment processing application. 5), it is determined whether or not the input operation is performed (S12). Here, in the flash ROM 32, the coordinates of the important key input reception icon 61 on the transaction content input screen to be processed by the payment processing application are registered in advance by the time the important key input reception icon 61 is displayed. Has been. The CPU 21 collates the coordinates of the important key input reception icon 61 with the touch input position (coordinates) to determine whether or not there is a touch input to the important key input reception icon 61.

  When it is determined that the input is a touch input to the important key input reception icon 61 (S12, YES), the CPU 21 determines whether or not a predetermined input operation is performed on the important key input reception icon 61 (S13). The predetermined input operation includes, for example, a selection operation of the important key input reception icon 61 shown in FIG. 5, a movement operation of the important key input reception icon 61 during the selection operation, and a selection release of the important key input reception icon 61 after the movement operation. It is an operation. More specifically, the predetermined input operation is a drag-and-drop operation. The important key input acceptance icon 61 is selected, dragged (moved) to either the YES icon 63 or the NO icon 65, and dropped at that position. The operation is (deselected).

  As a predetermined input operation on the important key input reception icon 61, for example, when the important key input reception icon 61 is dragged and dropped on the YES icon 63 (S13, YES), the CPU 21 performs the operation on the important key input reception icon 61. It is determined that a predetermined input operation (input confirmation) has been performed (input acceptance, S14). Thereby, the process of CPU21 shown in FIG. 4 is complete | finished. Further, as a predetermined input operation for the important key input reception icon 61, for example, when the important key input reception icon 61 is dragged and dropped on the NO icon 65 (S13, YES), the CPU 21 also inputs the important key. It is determined that a predetermined input operation (negative) has been performed on the reception icon 61 (input reception, S14). Thereby, the process of CPU21 shown in FIG. 4 is complete | finished.

  On the other hand, when a predetermined input operation for the important key input reception icon 61 is not performed, or when the operation for dragging and dropping the important key input reception icon 61 to the YES icon 63 is not performed after waiting for a predetermined time (S13). , NO), the CPU 21 maintains the state of the touch operation input in step S11 (S15), and the process of the CPU 21 returns to step S11.

  When the touch input detected by the touch input detection unit 3C is not determined to be a touch input to the important key input acceptance icon 61 (S12, NO), the CPU 21 detects the touch detected by the touch input detection unit 3C. If the input is a key (that is, a key other than an important key) (S16, YES), it is determined that an input operation has been performed (input acceptance, S14). If the input is not the key (S16, NO) ), The process of the CPU 21 returns to step S11. In addition, the process which CPU21 discriminate | determines input operation shown in FIG. 4 according to the program memorize | stored in flash ROM32 is equivalent to the input operation discrimination | determination part of the transaction terminal device which concerns on this invention.

  FIG. 5 is a diagram showing a screen displayed on the touch panel 3D mounted on the payment terminal device 1. On the display unit 3B of the touch panel 3D, an input screen for transaction contents to be processed for payment processing in the payment processing application is displayed, and various information 51 related to the payment processing is displayed on this input screen. The various information 51 related to the payment process displays, for example, a payment amount, a payment method, a card brand of a magnetic credit card, and items for checking the transaction details.

  Specifically, information on “Amount 12,345 yen”, “Payment once”, “Brand ***” (*** is the brand name of the credit card), “Are you sure? (Y / N)” Is displayed. In the transaction content input screen shown in FIG. 5, the touch input detection unit 3C can detect an operator's touch input to the input areas 51a, 51b, 51c, 51d corresponding to the display positions of these pieces of information. . Of the input areas 51a, 51b, 51c, 51d, for example, the input area 51d is displayed for confirming the input contents of the transaction contents, and is an important key (specific target) having an important meaning on the transaction content input screen. Equivalent to.

  A numeric keypad 53 as an example of a software keyboard is displayed below the information 51 relating to payment processing. Further, below the numeric keypad 53, an important key input acceptance icon 61, a YES icon 63, and a NO icon 65 provided for the CPU 21 to determine that a predetermined input operation for the important key has been performed are displayed. In the present embodiment, the important key is not limited to the confirmation necessity item (that is, “Y / N”) of the transaction content input corresponding to the input area 51d shown in FIG. It may be a sales registration key or a confirmation completion key.

  The contents displayed in the input areas 51a, 51b, 51c, 51d displayed on the display unit 3B of the touch panel 3D can be changed by touch-inputting any of the corresponding input areas. is there. For example, the sales amount is changed by tapping the numeric keypad 53 after tapping the input area 51a representing the amount. When the input area 51a is an important key and the sales amount is to be determined, the operator taps and selects the input area 51a, and then drags and drops the important key input acceptance icon 61 to the position of the YES icon 63. To do. Thereby, the sales amount (settlement amount) is fixed.

  In addition, the input area 51d of “Are you sure (Y / N)” that finally confirms various information 51 related to the settlement processing is described as an important key in this embodiment. When the operator displays “Are you sure? (Y / N)” or after tapping this important key to select it (see FIG. 5), the operator sets the important key input acceptance icon 61 to YES. A drag and drop operation is performed at the position of the icon 63. Thereby, the input confirmation of the transaction content is performed by the operator. On the other hand, when the operator drags and drops the important key input acceptance icon 61 to the position of the NO icon 65, the input confirmation of the transaction content is denied, so that the input item is changed again.

  As described above, when one of the various screens related to the payment processing performed with the payment destination device is displayed on the touch panel 3D, the payment terminal device 1 according to the present embodiment has a specific target on the screen. For example, an input operation on the important key input reception icon 61 is detected, whether or not the input operation on the important key input reception icon 61 is a predetermined input operation, and the input operation on the important key input reception icon 61 is predetermined. In the case of the input operation, a process corresponding to a predetermined input operation (for example, a request for a settlement process with a settlement destination apparatus after confirming the input of transaction contents) is executed.

  As a result, the settlement terminal device 1 performs an input operation on the important key input reception icon 61 displayed on the screen as a predetermined input operation as an operation having an important transaction meaning on the screen displayed on the touch panel 3D. If there is, a process corresponding to a predetermined input operation is executed, so that the operator performs an input operation having an important transaction meaning (that is, an important key input acceptance icon on the screen displayed on the touch panel 3D). (Execution of input operation on 61) can be made clear and easy to be conscious, and it is possible to suppress an erroneous operation of a software key (important key) having an important meaning in transactions.

  In addition, since the payment terminal device 1 displays a predetermined important key input acceptance icon 61 on the touch panel 3D on the screen related to payment processing, the important key is always used when performing an input operation on the important key on the screen displayed on the touch panel 3D. It is possible to make the operator clearly aware that a predetermined input operation for the input reception icon 61 is necessary.

  Further, the settlement terminal device 1 executes the settlement process for the important key when the drag and drop operation is performed on the important key input acceptance icon 61 on the screen displayed on the touch panel 3D. In view of the operation frequently used in a general-purpose PC (Personal Computer) or the like, it is possible to easily suppress an operator's erroneous operation.

  In the first embodiment described above, the important key input reception icon 61 is dragged and dropped in order to make the operator aware that the input operation is an important key, but the important key input reception icon 61 is used. The predetermined input operation is not limited to this drag and drop operation.

  For example, in the payment terminal device 1, on the screen displayed on the touch panel 3D, the important key input acceptance icon 61 is pressed and held for a predetermined time, and then one or more selection operations (for example, a double tap operation) are performed. In this case, the settlement process for the important key is executed in the same manner as when the drag and drop operation is performed on the important key input acceptance icon 61. Thereby, unlike the drag-and-drop operation, the settlement terminal device 1 does not need to move the important key input acceptance icon 61 on the screen, and further indicates an instruction medium (for example, an operator's finger or stylus) to the touch panel 3D. Since the operation range on the screen of the pen) may be small, it is possible to make the operator perform a predetermined input operation more easily. Note that a long press after one or more selection operations can be similarly performed.

(Background to the contents of the second embodiment)
First, before explaining the second embodiment, the process leading to the contents of the settlement terminal device 1 of the second embodiment will be explained.

  In the conventional transaction terminal device including the above-described Patent Document 1, when the operator does not perform any input operation for a predetermined time (for example, one minute), for example, prevention of screen burn-in and power saving in a PC. In order to achieve this, a transition has been made to a sleep mode (that is, a mode in which the power supply of the display unit of the touch panel is temporarily turned off).

  However, since the payment process may take a long time, the payment process is interrupted in the middle when the mode is shifted to the sleep mode. As a case where the payment process takes a long time, for example, the network environment between the payment terminal apparatus and the payment center is not good, and the communication process takes time. In addition, many payment terminal devices are connected to the payment center, and even if the payment terminal device transmits a request for payment processing (for example, credit inquiry), a payment processing response cannot be obtained from the payment destination device. Also mentioned. Furthermore, when the payment terminal device is configured with a thin client, the amount of data transferred through the network with the payment destination device is significantly increased compared to the conventional rich client. It is also possible to do.

  Therefore, once the payment process is interrupted, in order to resume the payment process, the operation to return from the sleep mode had to be performed. Therefore, it took time and often required time for the return process to wait for the customer. Sometimes it happened.

(Second Embodiment)
Therefore, in the second embodiment, when at least a screen related to payment processing is displayed, even when a state where there is no input operation from the operator continues for a predetermined time or more, the transition to the sleep mode is avoided. An example of a transaction terminal device that quickly completes transaction settlement processing will be described.

  Since the appearance of the settlement terminal device 1 of the second embodiment is the same as the appearance of the settlement terminal device of the first embodiment (see FIG. 1), the description thereof is omitted by using the same reference numerals. To do. Moreover, since the hardware configuration of the payment terminal device 1 in the second embodiment is also the same as that of the payment terminal device (see FIG. 2) of the first embodiment described above, the same reference numerals are used to explain the same. Is omitted. Hereinafter, an operation different from the above-described first embodiment, that is, an operation related to the control of whether or not to enter the sleep mode will be described.

  As in the first embodiment, the settlement terminal device 1 according to the present embodiment detects an operator's input operation on the screen when any screen is displayed on the touch panel 3D. When no input operation is detected for the above, the touch panel 3D is shifted to the sleep mode. In the sleep mode, the display unit 3B of the touch panel 3D turns off the screen, and the touch input detection unit 3C does not detect an input operation. In the sleep mode, the touch input detection unit 3C may detect an input operation.

  FIG. 6 is a flowchart for explaining a payment processing procedure of the payment terminal device 1 according to the second embodiment. Since each process of the flowchart shown in FIG. 6 is the same as each process of the flowchart shown in FIG. 3 in the first embodiment described above, a specific description of each process is omitted.

  However, since each process shown in FIG. 6 is a process related to a payment process, the payment terminal device 1 of the present embodiment can display the display unit 3B of the touch panel 3D even when an input operation on the screen of the display unit 3B of the touch panel 3D is not detected. Does not enter into sleep mode. More specifically, from the period indicated by the arrow f in FIG. 6 (that is, from the scan prompt display process for prompting the magnetic credit card to be read in step S1), confirmation of the transaction content that is the object of the settlement process in step S7. Until the result display processing), the settlement terminal device 1 does not shift the display unit 3B of the touch panel 3D to the sleep mode. In the receipt printing process in step S8, the settlement terminal device 1 may cause the display unit 3B of the touch panel 3D to shift to the sleep mode.

  In particular, in each process of steps S6 and S7 during communication with the payment destination apparatus, the payment terminal apparatus 1 omits the transition of the display unit 3B of the touch panel 3D to the sleep mode. Also, in each process of steps S1 to S5, it may be assumed that an operator's input operation takes time. For example, there are a case where a store clerk needs to take a seat and check a product, or a case where a customer cannot stay on the spot due to sudden business.

  Thus, considering the case where it is assumed that the operator's operation takes time, the payment terminal device 1 causes the display unit 3B of the touch panel 3D to shift to the sleep mode also in each processing of steps S1 to S5. May be.

  FIG. 7 is a flowchart for explaining the sleep mode transition processing procedure of the payment terminal device 1 according to the second embodiment.

  In FIG. 7, the CPU 21 determines whether or not the operator does not perform an input operation on the touch panel 3D according to a signal from the touch input detection unit 3C indicating whether or not the input operation is detected ( S21). For example, when any input operation is detected instead of no operation (S21, NO), the CPU 21 clears the count value (timer value) of the timer 21A to 0 (S22). Thereafter, the processing of the CPU 21 returns to step S21.

  On the other hand, when it is determined that there is no operation (S21, YES), the CPU 21 determines whether or not the timer 21A has elapsed for a predetermined time (for example, 1 minute) (S23).

  If the predetermined time has not elapsed (S23, NO), the processing of the CPU 21 returns to step S21.

  On the other hand, when the predetermined time has elapsed (S23, YES), the CPU 21 determines whether or not a settlement process is currently being performed (S24). For example, “under settlement processing” refers to a case where the above-described settlement processing application is activated and any one of steps S1 to S7 shown in FIG. 6 is being executed.

  When the payment process is in progress (S24, YES), the CPU 21 omits the transition of the display unit 3B of the touch panel 3D to the sleep mode and displays a screen related to the payment process displayed on the display unit 3B (for example, FIG. 8 (A)) is continued (S25). Thereafter, the processing of the CPU 21 returns to step S21.

  On the other hand, when the payment process is not in progress (S24, NO), the CPU 21 shifts the display unit 3B of the touch panel 3D to the sleep mode, turns off the display unit 3B (see FIG. 8B), and darkens the screen. (S26). Thereafter, the processing of the CPU 21 returns to step S21. The process in which the CPU 21 controls the transition to the sleep mode shown in FIG. 7 according to the program stored in the flash ROM 32 corresponds to the sleep mode control unit of the transaction terminal device according to the present invention.

  FIG. 8A is a diagram showing a screen related to the payment process. FIG. 8B is a diagram illustrating a screen of the display unit 3B when the mode is shifted to the sleep mode. The input reception icons MK1, YES icon MK2, and NO icon MK3 in FIG. 8A correspond to the important key input reception icon 61, the YES icon 63, and the NO icon 65 shown in FIG. 5 of the first embodiment, respectively. In FIG. 8B, the display portion 3B is turned off by making the screen white.

  As described above, when any screen is displayed on the touch panel 3D, the settlement terminal device 1 of the present embodiment detects an input operation on the screen, but the input operation is not detected for a certain time or longer on the screen. Shifts the touch panel 3D to the sleep mode. Further, the settlement terminal device 1 does not detect an input operation on the screen for a certain period of time or more while at least a screen related to the settlement process performed with the settlement destination device is displayed on the display unit 3B of the touch panel 3D. However, the transition to the sleep mode of the touch panel 3D is omitted, and the display of the content displayed on the display unit 3B of the touch panel 3D is continued.

  Thereby, the payment terminal device 1 is in a state where there is no input operation from the operator for a predetermined period of time while at least a screen related to the payment processing performed with the payment destination device is displayed on the display unit 3B of the touch panel 3D. Even if it continues for the above, since the transition to the sleep mode of the touch panel 3D can be avoided, there is no need to temporarily interrupt the payment process, and there is no need to perform an input operation to return from the sleep mode. The content settlement process can be completed quickly.

  Further, the settlement terminal device 1 shifts to the sleep mode of the display unit 3B of the touch panel 3D while communicating with the settlement processing of the transaction content (for example, credit inquiry and sales registration) with the settlement destination device. Since the display of the content displayed on the display unit 3B of the touch panel 3D is continued, it is possible to avoid interruption of communication with the settlement destination apparatus, and settlement processing with the settlement destination apparatus. Can be completed reliably.

(Background to the contents of the third embodiment)
First, before explaining the third embodiment, the background to the contents of the settlement terminal device 1 of the third embodiment will be explained.

  In the conventional transaction terminal device including the above-described Patent Document 1, if the next input operation is not detected even after a predetermined time (for example, 1 minute) has elapsed since the operator's input operation was detected, the screen burn-in occurs. In order to prevent or save power, the screen has been shifted to the sleep mode. Further, when the transaction terminal device detects some input operation of the operator during the sleep mode, the transaction terminal device cancels the sleep mode of the screen and displays the screen that was displayed immediately before the transition to the sleep mode.

  However, in a conventional transaction terminal device, when some input operation contrary to the operator's intention is detected and then the sleep mode is entered (for example, the operator touches the touch panel without noticing or the input is mistakenly recognized as input) When an operation (so-called erroneous operation) is performed and then the operator enters the sleep mode because of no operation for a certain period of time, the following situation is assumed. That is, when the operator performs some input operation on the transaction terminal device before shifting to the sleep mode, the transaction terminal device displays a screen that is not intended for the operator when the sleep mode is canceled. There was a thing.

  As a result, there is a problem that the operator is confused about the display of the screen that he / she does not intend to use, and has to spend a little time and effort before starting the input operation which was originally planned.

(Third embodiment)
Therefore, in the third embodiment, an example of a transaction terminal device that suppresses display of a screen unintended by the operator immediately after the sleep mode of the transaction terminal device is canceled and improves convenience of input operation for the operator will be described. To do.

  Since the appearance of the settlement terminal device 1 of the third embodiment is the same as the appearance of the settlement terminal device of the first embodiment (see FIG. 1), the description thereof is omitted by using the same reference numerals. To do.

  FIG. 9 is a block diagram specifically illustrating an example of a hardware configuration of the payment terminal device 1 according to the third embodiment. Further, in the hardware configuration of the payment terminal device 1, the same components as those of the payment terminal device 1 of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In addition to the timer 21A described in the first embodiment, the CPU 21 further includes a use frequency counter 21B that counts the number of displays (display frequency, use frequency) of a screen (for example, a menu screen) displayed on the display unit 3B.

  The usage frequency counter 21B counts the number of display times on the display unit 3B of the touch panel 3D of each menu screen for a plurality of menu screens to which a predetermined hierarchical relationship (hierarchical structure, for example, see FIG. 10) is assigned. For example, when the CPU 21 reads out a menu screen corresponding to the contents of various applications registered in advance in the flash ROM 32 and displays the menu screen on the display unit 3B of the touch panel 3D, the usage frequency counter 21B displays the value of the number of times the corresponding menu screen is displayed. Is incremented by “1”. The CPU 21 preferably stores the date / time information counted by the timer 21A in the usage frequency counter 21B when the usage frequency counter 21B increments the display count.

  As will be described later, this frequently used (highly displayed) menu screen has a return destination when the menu screen assigned to a lower hierarchy than the hierarchy corresponding to the menu screen is released from the sleep mode (that is, , A screen displayed on the display unit 3B of the touch panel 3D).

  FIG. 10 is a diagram illustrating a hierarchical structure of a plurality of menu screens displayed on the display unit 3B. Data representing a plurality of menu screens and their hierarchical structure is stored in the flash ROM 32 in advance. In the hierarchical structure shown in FIG. 10, for example, a menu screen belonging to an upper menu screen group (hereinafter referred to as an upper menu screen) is assigned to the left side of the boundary line of the partition line b, and is subordinate to the right side of the boundary line of the partition line b. Menu screens belonging to the menu screen group (hereinafter, lower menu screens) are assigned. In FIG. 10, for example, a lower menu screen is developed from a higher menu screen.

  In FIG. 10, for example, a root menu, a maintenance menu, and a shutdown menu screen are allocated as the top-level screen. Menu screens such as card payment, business, and general-purpose are assigned (expanded) as menu screens below the menu screen of the root menu.

  Further, menu screens of credit card payment, debit card payment, electronic money prepaid payment, and electronic money post-pay payment are assigned as menu screens lower than the card payment menu screen.

  In addition, menu screens for magnetic card settlement and IC card settlement are assigned as menu screens lower than the menu screen for credit card settlement.

  In addition, menu screens for scan prompt, brand selection, amount input, payment method / count input, PAD signature input, payment request transmission, payment result display, and receipt printing are assigned as menu screens lower than the magnetic card payment menu screen. It is done. Similarly, menu screens for scan prompt, brand selection, amount input, payment method / number of times input, PIN input, payment request transmission, payment result display, and receipt printing are assigned as menu screens below the IC card payment menu screen. It is done.

  On the other hand, menu screens for sales management and sales report reports are assigned as menu screens lower than the business menu screen. Similarly, menu screens of e-mail and network browser are assigned as menu screens lower than the general-purpose menu screen. On the other hand, software version management and user management menu screens are assigned as menu screens below the maintenance menu screen.

  In the present embodiment, in the menu screen on the left side of the partition line b shown in FIG. 10 (that is, the upper menu screen), when returning to the sleep mode after returning to the sleep mode (that is, canceling the sleep mode), the return destination Is a predetermined screen (that is, an upper menu screen (see later)).

  On the other hand, in the menu screen on the right side of the partition line b shown in FIG. 10 (that is, the lower menu screen), when returning to the sleep mode after returning to the sleep mode, the return destination is the touch panel 3D immediately before the transition to the sleep mode. The menu screen displayed on the display unit 3B is displayed.

  FIG. 11 is a flowchart illustrating a payment processing procedure of the payment terminal device 1 according to the third embodiment. Since each process of the flowchart shown in FIG. 11 is the same as each process of the flowchart shown in FIG. 3 in the first embodiment described above, a detailed description of each process is omitted.

  In the payment terminal device 1 of the third embodiment, unlike the above-described second embodiment, the CPU 21 prompts the reading of the magnetic credit card in the period indicated by the arrow g in FIG. 11 (that is, step S1). From the display process of the scan prompt to the printing process as a receipt of the confirmation result of various input items of the transaction contents in step S8), the display unit 3B of the touch panel 3D is shifted to the sleep mode, as indicated by this arrow g. During the period, when returning from the sleep mode, the screen displayed immediately before the transition to the sleep mode is displayed as the return destination screen.

  FIG. 12 is a flow chart for explaining a return processing procedure from the sleep mode of the payment terminal device 1 according to the third embodiment. The return process shown in FIG. 12 is executed when an event of some input operation (for example, key operation) by the operator occurs on the settlement terminal device 1. The event of the input operation is a power switch 3E press interruption, a touch detection interruption to the touch input detection unit 3C, or the like. The occurrence of the event may be recognized by polling.

  In FIG. 12, the CPU 21 determines the type (including the type and level of the screen immediately before) displayed on the display unit 3 </ b> B of the touch panel 3 </ b> D immediately before the transition to the sleep mode (the same applies hereinafter) (S <b> 31). . For example, the information of the immediately preceding screen can be grasped by the CPU 21 examining the type of the screen read at the latest date and time held in the usage frequency counter 21B.

  The CPU 21 identifies whether the previous screen is a menu screen higher than the partition line b shown in FIG. 10 (that is, the left menu screen) or a lower menu screen (that is, the right menu screen). (S32).

  When the immediately preceding screen is a menu screen lower than the partition line b shown in FIG. 10 (S32, NO), the CPU 21 causes the display unit 3B of the touch panel 3D to continue displaying the immediately preceding screen (S33). . For example, since the menu screen corresponding to the specific processing content related to the payment processing is a lower screen than the partition line b shown in FIG. 10, the payment terminal device 1 displays the previous screen when returning from the sleep mode. Display as it is.

  On the other hand, when the previous screen is a menu screen higher than the partition line b shown in FIG. 10 (S32, YES), the CPU 21 sets a predetermined screen on the display unit 3B of the touch panel 3D from the previous screen. The upper menu screen is also displayed (S34). After the process of step S33 or step S34, the process of the CPU 21 ends. As described above, the CPU 21 needs to switch the menu screen on the display unit 3B of the touch panel 3D after the sleep mode is canceled according to the type of the screen (menu screen) displayed immediately before the transition to the sleep mode. Determine no.

  FIG. 13A is a diagram showing a menu screen displayed immediately before the transition to the sleep mode. FIG. 13B is a diagram showing a higher-level menu screen displayed when returning from the sleep mode on the menu screen of FIG. FIG. 13C is a diagram showing a menu screen that was displayed immediately before the transition to the sleep mode. FIG. 13D is a diagram showing a menu screen as a screen immediately before being displayed when returning from the sleep mode in the menu screen of FIG. In other words, the menu screen shown in FIG. 13C is the same as the menu screen shown in FIG.

  As described above, in the third embodiment, the settlement terminal device 1 detects an input operation on the menu screen when any menu screen related to the settlement process is displayed on the display unit 3B of the touch panel 3D. When an input operation is not detected on the screen for a certain time or longer, the display unit 3B of the touch panel 3D is shifted to the sleep mode. Further, when the payment terminal device 1 shifts to the sleep mode and then the sleep mode is canceled due to the detection of an input operation, the menu displayed on the display unit 3B of the touch panel 3D immediately before the shift to the sleep mode. It is determined whether or not it is necessary to switch the menu screen displayed on the display unit 3B of the touch panel 3D according to the type of the screen.

  As a result, the payment terminal device 1 is configured so that the type of the menu screen displayed immediately before the transition to the sleep mode varies depending on whether the operator performs an input operation based on his / her own judgment or consciousness. When canceling the sleep mode of the 3D display unit 3B, the menu screen after canceling the sleep mode is switched according to the type (type) of the menu screen displayed immediately before the transition to the sleep mode. Unintended display of the menu screen can be suppressed, and the convenience of the input operation for the operator can be improved.

  Further, the settlement terminal device 1 is configured such that the menu screen displayed on the display unit 3B of the touch panel 3D immediately before the transition to the sleep mode is assigned to a higher hierarchy than a predetermined hierarchy defined in a predetermined hierarchy relationship. In this case, the menu screen displayed on the display unit 3B of the touch panel 3D immediately before shifting to the sleep mode is switched to a predetermined screen and displayed on the display unit 3B of the touch panel 3D. Thereby, when the menu screen assigned to the hierarchy higher than the predetermined hierarchy is displayed immediately before the transition to the sleep mode, the settlement terminal device 1 specifically specifies which process the operator intends to perform. If it is noticed that there is a high possibility that the user has selected or searched, the menu screen to be displayed on the display unit 3B of the touch panel 3D after the sleep mode is canceled is changed to a predetermined screen. The processing to be performed can be selected easily.

  Further, the settlement terminal device 1 enters the sleep mode when the menu screen displayed on the display unit 3B of the touch panel 3D immediately before shifting to the sleep mode is a menu screen assigned to a lower hierarchy than a predetermined hierarchy. The menu screen displayed on the display unit 3B of the touch panel 3D immediately before the transition is continued. Thereby, when the menu screen assigned to the lower hierarchy than the predetermined hierarchy is displayed immediately before the transition to the sleep mode, the settlement terminal device 1 specifically performs any process, for example. Paying attention to the high possibility that it was intended to be executed, the menu screen displayed on the display unit 3B of the touch panel 3D after the sleep mode is canceled is displayed on the menu screen displayed immediately before the transition to the sleep mode. By continuing the display as it is, processing desired by the operator can be quickly executed.

  In the present embodiment, in the menu screen on the left side of the partition line b shown in FIG. 10, the return destination when returning from the sleep mode is the upper screen as the predetermined screen. It may be. For example, the top menu screen in payment processing (that is, the card payment menu screen) may be the return destination. As a result, the predetermined screen is a screen assigned to a layer higher than the layer corresponding to the screen displayed on the touch panel immediately before the transition to the sleep mode among the plurality of screens related to the payment process. The device 1 can easily select a process or menu desired by the operator as a screen to be displayed on the display unit 3B of the touch panel 3D after the sleep mode is canceled.

  In addition, a specific menu screen designated by an acquirer, a settlement processor administrator, or the like may be the return destination. As a result, the predetermined screen is a screen assigned to any one of the predetermined hierarchical relationships designated in advance in response to a predetermined input operation by an acquirer, an administrator of the payment processor, or the like. 1 displays a screen assigned to a hierarchy corresponding to a predetermined input operation (for example, an instruction from an acquirer or a payment processor) as a screen to be displayed on the display unit 3B of the touch panel 3D after the sleep mode is canceled. By displaying the menu that is the starting point when the operator is lost or troubled by the operation, the convenience for the operation of the operator can be improved.

  Of the plurality of menu screens held by the flash ROM 32, a screen whose usage frequency counted by the usage frequency counter 21B is a predetermined value or more (that is, a screen with high usage frequency) may be the return destination. Thereby, since the predetermined screen is a screen related to the payment processing, the display frequency on the display unit 3B of the touch panel 3D is equal to or higher than the predetermined value, and the payment terminal device 1 is assigned to a higher hierarchy than the predetermined hierarchy. As a menu screen to be displayed on the display unit 3B of the touch panel 3D after the sleep mode is canceled, a process or menu frequently used by the operator is displayed, thereby providing a sense of security and convenience for the operation of the operator. Can be improved. In addition, when there are a plurality of frequently used screens, the payment terminal device 1 may use, for example, a screen higher than the previous screen as the return destination.

(Background to the contents of the fourth embodiment)
First, before explaining the fourth embodiment, the process leading to the contents of the payment terminal device 1 of the fourth embodiment will be explained.

  In the above-described small payment terminal of Patent Document 1, an information display area and an information input area are set in the display area of the touch panel display unit, and a numeric keypad image pattern is displayed in the information input area, thereby enabling an input operation on the numeric keypad image pattern. To. In addition, this small payment terminal includes a printer, prints information such as the result of payment processing on a roll paper incorporated therein in advance, and discharges a receipt on which the printed content is printed from a paper discharge port. In this small payment terminal, electric power is supplied from an external commercial power source (for example, AC 100 V) via an AC adapter housed inside the housing.

  However, in the configuration of Patent Document 1, a large amount of power is consumed to drive the paper feed mechanism of the small settlement terminal and drive the print head for printing on the print paper while the printer is operating. For this reason, while the printer is operating (that is, during printing), a large amount of electric power is consumed inside the small payment terminal, and the temperature inside the small payment terminal thus rapidly increases. Therefore, when the temperature inside the small payment terminal rises, there is a possibility that an electronic component or the like mounted on the internal circuit board may be affected by malfunction or deterioration. For this reason, there has been a demand for suppressing the power consumption of the small payment terminal and suppressing the total amount of current flowing through the AC adapter. In addition, it is necessary to use parts with large volume and weight that can supply high power and large current for the AC adapter, and in order to install in stores where the installation space is not widely secured, There was a demand to reduce the size of the adapter.

(Fourth embodiment)
Therefore, in the fourth embodiment, by temporarily suppressing or stopping some functions or processes while the printer is operating, the total amount of current flowing into the power supply unit housed in the housing is reduced. The example of the transaction terminal device which reduces and suppresses power consumption is demonstrated.

  The external appearance of the payment terminal device 1 of the fourth embodiment is the same as the external appearance (see FIG. 1) of the payment terminal device of the first embodiment described above. To do.

  FIG. 14 is a block diagram specifically illustrating an example of a hardware configuration of the payment terminal device 1 according to the fourth embodiment. Further, in the hardware configuration of the payment terminal device 1, the same components as those of the payment terminal device 1 of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In addition to the configuration of the payment terminal device 1 shown in FIG. 1, the payment terminal device 1 shown in FIG. 14 includes a backlight 46 as an example of an illumination unit that lights up and illuminates the display unit 3B that displays a screen related to payment processing. It further has a backlight control unit 47 that performs various controls of turning on, dimming (lighting), and turning off the backlight 46. The backlight control unit 47 is connected to the CPU 21.

  The backlight control unit 47 performs various controls such as turning on, dimming, and turning off the backlight 46 in accordance with an instruction from the CPU 21. For example, the backlight 46 is turned off or gradually reduced so that the backlight 46 is turned off. Is turned off or dimmed. Note that the backlight control unit 47 may have a light control function capable of continuously changing the light emission amount of the backlight 46.

  The payment terminal device 1 shown in FIG. 14 includes a power supply unit 48 for supplying power as a power source to each unit included in the information processing unit 20. The power supply unit 48 is accommodated in the housing of the settlement terminal device 1 and can be realized using, for example, a relatively small capacity AC adapter.

  The flow of the payment process in the payment terminal device 1 of the present embodiment is the same as the operation procedure (see FIG. 3) in the payment terminal device 1 of the first embodiment described above. The operation will be described.

  FIG. 15 is a flowchart for explaining the operation procedure of receipt printing in step S8 shown in FIG. 3 of the payment terminal device 1 of the fourth embodiment.

  In FIG. 15, the CPU 21 starts a process of printing (printing) the confirmation result of the transaction content that is the object of the settlement process as a receipt (S41). For example, at the same time as starting the printing in step S41, the CPU 21 gives an instruction to the backlight control unit 47, and turns off or dims the backlight 46 (S42). From the viewpoint of suppressing power consumption, the CPU 21 preferably turns off the backlight 46. The operation of turning off or dimming the backlight 46 is performed before the printing operation is actually started or after the printing operation is started after the printing process is started in step S41. From the viewpoint of suppressing power consumption, before starting the printing operation such as the operation of the print head and motor of the printer module 4 (both not shown) and the print data transfer processing from the printer I / F 41 to the printer module 4. In addition, it is desirable to turn off or dimm the backlight.

  The CPU 21 determines whether printing has been completed (S43). If printing has not ended (S43, NO), the processing of the CPU 21 returns to step S42.

  On the other hand, when printing is completed (S43, YES), the CPU 21 gives an instruction to the backlight control unit 47, and turns on the backlight 46 that has been turned off or dimmed (S44). Thereafter, the process of the CPU 21 returns to the time point of the process of step S8 shown in FIG. That is, the operation of the payment terminal device 1 ends.

  The CPU 21 starts printing in step S41 and simultaneously detects the input operation of the touch panel 3D (that is, the screen UI (User Interface)) in parallel with the turning-off / darkening control of the backlight 46 in step S42. Processing for stopping processing and display processing such as graphic processing and liquid crystal display panel driver display (S42A) may be performed. In other words, the CPU 21 stops the detection of the touch input operation by the touch input detection unit 3C in the screen UI stop process (that is, the touch panel 3D stop process), and the screen by the display unit 3B (for example, a screen related to the settlement process). ) Is stopped. Thereafter, the processing of the CPU 21 proceeds to step S43.

  When printing is completed in step S43, the CPU 21 turns on the backlight 46 in step S44 and performs a process of canceling the stop of the screen UI (touch panel 3D) (S44A). Thereafter, the process of the CPU 21 ends, and the process returns to the time point of the process of step S8 shown in FIG. That is, the operation of the payment terminal device 1 ends.

  As described above, the payment terminal device 1 according to the fourth embodiment illuminates the display unit 3B of the touch panel 3D that displays a screen related to payment processing, for example, while information related to payment processing is printed in the printer module 4. Is dimmed or turned off.

  As a result, the settlement terminal device 1 temporarily and temporarily reduces the backlight 46 that controls the illumination on the display unit 3B of the touch panel 3D as a part of functions or processing while the printer module 4 is operating. Since (suppressed) or extinguished (stopped), the total amount of current flowing into the power supply unit 48 (for example, AC adapter) accommodated in the housing of the settlement terminal device 1 can be reduced, and further, the settlement terminal device The power consumption in 1 can be suppressed.

  Further, since the payment terminal device 1 turns on the backlight 46 that has been dimmed or turned off after the printer module 4 finishes printing the information related to the payment processing, the back-up device 1 is turned off during periods other than during printing where power consumption increases. Even if the lighting of the light 46 is continued, an increase in the total amount of current flowing into the power supply unit 48 accommodated in the housing of the payment terminal device 1 can be suppressed.

  Further, the payment terminal device 1 detects an input operation on the screen related to the payment process in addition to the preferential dimming or extinguishing of the backlight 46 while the information related to the payment process is printed by the printer module 4. Since the function of the touch panel 3D including the touch input detection unit 3C is temporarily stopped, an increase in the total amount of current flowing into the power supply unit 48 accommodated in the housing of the payment terminal device 1 can be further suppressed. .

  In addition, since the payment terminal device 1 cancels the stop of the detection of the input operation in the touch input detection unit 3C of the touch panel 3D after the printer module 4 finishes printing the information related to the payment process, the printing with an increase in power consumption is being performed. In the excluded period, even if the input operation detection process is continued in addition to the lighting of the backlight 46, an increase in the total amount of current flowing into the power supply unit 48 housed in the housing of the settlement terminal device 1 is suppressed. be able to.

  Further, the payment terminal device 1 temporarily performs a process of supplying power to the display unit 3B of the touch panel 3D in addition to dimming or turning off the backlight 46 while the information related to the payment process is printed by the printer module 4. Therefore, the increase in the total amount of current flowing into the power supply unit 48 accommodated in the housing of the payment terminal device 1 can be further suppressed.

  Moreover, since the payment terminal device 1 cancels the stop of the power supply to the display unit 3B of the touch panel 3D after the printer module 4 finishes printing the information related to the payment process, the payment terminal device 1 is in a period other than during the time when the power consumption increases. Even if the power supply to the display unit 3B of the touch panel 3D is continued in addition to the lighting of the backlight 46, the total amount of current flowing into the power source unit 48 housed in the housing of the settlement terminal device 1 is increased. Can be suppressed.

  While various embodiments have been described above with reference to the drawings, it goes without saying that the present invention is not limited to such examples. 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 invention.
