It is a figure which shows an example of the screen displayed on the display part for operators and the display part for customers in the clone mode of the POS terminal shown in FIG. 1, (a) shows an example of the screen displayed on the display part for operators. FIG. 4B is a diagram illustrating an example of a screen displayed on the customer display unit. It is a figure which shows an example of the password input screen in the POS terminal shown in FIG. 3 is a flowchart for explaining an operation in a clone mode of the POS terminal shown in FIG. 1. It is a figure which shows an example of the external appearance of a POS terminal.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of an embodiment of a POS terminal to which an input control device of the present invention is applied.

  As shown in FIG. 1, the POS terminal 1 of the present embodiment is a control unit 10 having a POS application for controlling the POS terminal 1, an image control unit 20, and a first display unit that accepts input by a touch panel method. There is provided an operator display unit 30 and a customer display unit 40 which is a second display unit that accepts input by a touch panel method.

  In the present embodiment, the operator display unit 30 and the customer display unit 40 adopt a touch panel method as a method of receiving an input, but the present invention is not limited to this, and for example, an input is received by a mouse, a keyboard, or the like. You may do it.

  The screens displayed on the operator display unit 30 and the customer display unit 40 include various buttons (not shown) that are selected by pressing by a store clerk or a customer. These various buttons are images generated using a POS application, and are associated with different processes.

  The POS application includes a clerk POS application for controlling the operator display unit 30 and a customer POS application for controlling the customer display unit 40.

  Here, the screens displayed on the operator display unit 30 and the customer display unit 40 differ depending on the display mode. Below, the display mode in the POS terminal 1 shown in FIG. 1 will be described.

  There are two types of display modes in the POS terminal 1 shown in FIG. 1; an expansion mode and a clone mode.

  In the extended mode, the operator display unit 30 displays a screen that is generated using the clerk POS application and is operated by the clerk. On the other hand, the customer display unit 40 displays a screen generated by the customer POS application and used by the customer to operate. That is, in the extended mode, the screen displayed on the operator display unit 30 and the screen displayed on the customer display unit 40 are different.

  In the expansion mode, both the operator display unit 30 and the customer display unit 40 accept mouse input. In mouse input, the pressed button is recognized, and selected image information that is information indicating the recognized button is output.

  On the other hand, in the clone mode, the same screen generated using the POS application is displayed on the operator display unit 30 and the customer display unit 40.

  In the clone mode, the operator display unit 30 accepts mouse input, and the customer display unit 40 accepts OCX (OLE Custom Control) input. In the OCX input, the position of the pressed button is recognized, and selected position information that is information indicating the recognized position is output. The OCX will be described later.

  Here, when the OCX input is accepted, the mouse input cannot be accepted. This is because the pressed button is recognized by the mouse input, whereas the position of the pressed button is recognized by the OCX input.

  Accordingly, in the clone mode, the position of the button that can be selected on the customer display unit 40 is associated with the process associated with the button. On the other hand, the position of a button other than the buttons that can be selected on the customer display unit 40 is not associated with the process associated with the button. Thereby, the button which can be selected in the display part 40 for customers can be limited.

  Further, in the clone mode, OCX, which is an image having the same shape as the button, is pasted on a button that can be selected on the customer display unit 40. In other words, the OCX having the same shape as the button is displayed on the button in an overlapping manner.

  OCX is a program part for Windows (registered trademark) created using OLE (Object Linking and Embedding). OCX can be created independently by the user. OLE is a mechanism for transferring and sharing data between applications in Windows (registered trademark). By using OLE, information created by another application can be embedded in an image or text created by a certain application.

  2 is a diagram showing an example of a screen displayed on the operator display unit 30 and the customer display unit 40 in the clone mode of the POS terminal 1 shown in FIG. FIG. 5B is a diagram showing an example of the displayed screen, and FIG. 5B is a diagram showing an example of the screen displayed on the customer display unit 40.

  In FIG. 2, buttons A to D are buttons that can be selected on the customer display unit 40. On the other hand, the buttons E and F cannot be selected on the customer display unit 40.

  In the clone mode, as shown in FIG. 2, the screen displayed on the operator display unit 30 and the screen displayed on the customer display unit 40 are the same. However, the part shown with the broken line in the figure of FIG.2 (b) is a part by which OCX was affixed.

  Here, the reason why the OCX is pasted on the buttons that can be selected on the customer display unit 40 will be described.

  By using OCX, an OCX event can be set. An OCX event is a process executed when OCX is selected, and includes, for example, an OCX touch event and an OCX release event. The OCX touch event is a process executed when the part where the OCX is pasted is pressed, and the OCX release event is the part where the OCX is pasted after the part where the OCX is pasted is pressed. It is a process that is executed when a given part is released.

  Normally, in the case of OCX input, the shape of the OCX does not change even if the portion where the OCX is pasted is selected. In this case, the person who has pressed the OCX cannot determine whether or not it has been selected. In order to avoid this, for example, when a portion to which the OCX is pasted is selected, an OCX touch event that changes the shape of the OCX to the shape of pressing the button may be set. Thereafter, when the portion where the OCX is pasted is released, an OCX release event for returning the shape of the OCX to a shape where the button is not pressed may be set.

  Referring to FIG. 1 again, the control unit 10 uses the POS application to generate a plurality of buttons associated with different processes. At this time, the control unit 10 determines whether to set the display mode to the expansion mode or the clone mode according to the type of screen to be displayed. When the clone mode is determined, the control unit 10 causes the operator display unit 30 and the customer display unit 40 to display a screen including a plurality of generated buttons. When it is determined that the clone mode is set, the control unit 10 outputs a switching signal to the customer display unit 40. When the customer display unit 40 receives the switching signal, the customer display unit 40 receives an OCX input. In addition, when it is determined that the clone mode is set, the control unit 10 determines a position at which a button that can be selected on the customer display unit 40 among the plurality of generated buttons is displayed on the customer display unit 40. The image position information shown is associated with the process associated with the button. The buttons that can be selected on the customer display unit 40 are determined in advance according to the type of screen. Moreover, the control part 10 receives the selection image information output from the display part 30 for operators, and performs the process matched with the button which the received selection image information shows. In addition, the control unit 10 receives the selection position information output from the customer display unit 40 and executes a process associated with the image position information that matches the received selection position information.

  The image control unit 20 has the same shape as a button that can be selected on the customer display unit 40 among the plurality of buttons generated by the control unit 10 in the clone mode, and a predetermined OCX event is set. Generated OCX. Then, the image control unit 20 causes the customer display unit 40 to display the generated OCX on a button that can be selected on the customer display unit 40. In addition, the image control unit 20 associates the generated OCX with the above-described image position information. Then, the image control unit 20 receives the selected position information output from the customer display unit 40, and executes the OCX event set in the OCX associated with the image position information that matches the received selected position information. This OCX event is, for example, the OCX touch event or the OCX release event as described above.

  Hereinafter, an operation in the clone mode of the POS terminal 1 configured as described above will be described. Here, a case where a customer inputs a password from the customer display unit 40 will be described. Note that the password input screen for inputting the password is displayed in the clone mode.

  FIG. 3 is a diagram showing an example of a password input screen in the POS terminal 1 shown in FIG.

  As shown in FIG. 3, the password input screen includes numeric buttons 51 to 9 for inputting a password, a confirm button 52 for confirming the input password, and a cancel button 53 for interrupting the password input. Is arranged. In addition, as shown in FIG. 3, an input display box 54 is displayed on the password input screen to display the input password as “*” and indicate the number of digits of the input password. Here, the numeric buttons 51 and the confirm button 52 are buttons that can be selected on the customer display unit 40.

  FIG. 4 is a flowchart for explaining the operation in the clone mode of the POS terminal 1 shown in FIG.

  First, the store clerk selects a password input screen display by pressing a button displayed on the operator display unit 30.

  The operator display unit 30 that has received the selection from the store clerk outputs a signal for instructing the display of the password input screen to the control unit 10.

  The control unit 10 receives a signal output from the operator display unit 30. Here, the received signal instructs the display of the password input screen for displaying in the clone mode. Therefore, the control unit 10 outputs a switching signal to the customer display unit 40. As a result, the customer display unit 40 does not accept mouse input and accepts OCX input (step S1).

  Next, the control unit 10 generates a plurality of buttons as shown in FIG. 3 using a POS application, and displays a password input screen including the generated plurality of buttons as an operator display unit 30 and a customer display unit 40. (Step S2).

  And the control part 10 respond | corresponds to the image position information which shows the position where the button which can be selected in the display part 40 for customers among the several produced | generated buttons is displayed in the display part 40 for customers, and the button The attached process is associated (step S3). Here, for example, it is assumed that the image position information indicating the position where the numeric button 51 is displayed on the customer display unit 40 and the process of displaying “*” in the input display box 54 are associated with each other.

  The image control unit 20 generates an OCX having the same shape as a button that can be selected on the customer display unit 40 among the plurality of buttons generated by the control unit 10 and in which a predetermined OCX event is set. To do. Here, it is assumed that when OCX is selected, an OCX touch event that changes the shape of the OCX to the shape of pressing the button is set. Further, it is assumed that an OCX release event is set to return the shape of the OCX to a shape where the button is not pressed when the portion to which the OCX is pasted is released.

  Next, the image control unit 20 displays the generated OCX on the button that can be selected on the customer display unit 40 in the customer display unit 40 (step S4). Here, the generated OCX is displayed on the numeric buttons 51 and the confirmation button 52.

  Then, the image control unit 20 associates the generated OCX with the image position information (step S5).

  The customer inputs the password by pressing the OCX displayed as the numeric button 51 displayed on the customer display unit 40.

  The customer display unit 40 recognizes the position where the button pressed by the customer is displayed (step S6), and outputs selected position information indicating the recognized position.

  The image control unit 20 that has received the selected position information output from the customer display unit 40 executes an OCX event set in the OCX associated with the image position information that matches the received selected position information (step S7). ). Here, the image control unit 20 changes the shape of the OCX to a shape where the button is pressed, and then returns the shape of the OCX to a shape where the button is not pressed.

  The control unit 10 that has received the selected position information output from the customer display unit 40 executes a process associated with the image position information that matches the received selected position information (step S8). Here, the control unit 10 displays “*” in the input display box 54.

  When the store clerk presses a button displayed on the operator display unit 30, the operator display unit 30 outputs selected image information indicating the pressed button. Then, the control unit 10 that has received the image selection signal output from the operator display unit 30 executes processing associated with the button indicated by the received image selection signal.

  In this case, for example, when the store clerk selects the numeric button 51 displayed on the operator display unit 30, the control unit 10 receives image selection information indicating the numeric button 51. Therefore, a process associated with the numeric button 51, that is, a process of displaying “*” in the input display box 54 is executed. In order to avoid this, in the clone mode, the process associated with the button that can be selected on the customer display unit 40 is not executed even when the control unit 10 receives selected image information indicating the button. Just keep it.

  As described above, in the present embodiment, a plurality of buttons associated with different processes are generated, and the generated buttons are displayed on the operator display unit 30 and the customer display unit 40. Then, among the plurality of generated buttons, the image position information indicating the position where the predetermined button is displayed on the customer display unit 40 is associated with the process associated with the predetermined button. It is done.

  Further, when receiving the selection of the displayed button, the operator display unit 30 outputs selected image information indicating the selected button, and when the customer display unit 40 receives the selection of the displayed button, the selection is performed. The selected position information indicating the position where the displayed button is displayed is output.

  When the selected image information is output from the operator display unit 30, a process associated with the button indicated by the selected image information is executed. When the selected position information is output from the customer display unit 40, A process associated with the image position information that matches the selected position information is executed.

  Thereby, it is possible to display the same content on the two display units of the operator display unit 30 and the customer display unit 40 while avoiding a decrease in operability.

  In the present invention, the processing in the input control device is recorded on a recording medium readable by the input control device, in addition to the processing realized by the dedicated hardware described above. The program recorded on the recording medium may be read by the input control device and executed. The recording medium readable by the input control device refers to a HDD incorporated in the input control device in addition to a transferable recording medium such as a flexible disk, a magneto-optical disk, a DVD, and a CD.
