The cashless payments performed by the second payment processing unit 98 may include cashless payments other than those that can be executed by the first payment processing unit 80 of the extension device 7. For example, the second payment processing unit 98 executes processing related to the two-dimensional barcode payment by displaying a two-dimensional barcode for the two-dimensional barcode payment on the display unit 95 and using the connection unit 99 to communicate with a server of a payment agency or two-dimensional barcode payment institution via the extension device 7 (connection unit 81) and / or the image forming device 3 (connection unit 45, communication unit 43). Examples of two-dimensional barcode payments include PayPay from PayPay Corporation, Rakuten Pay from Rakuten Payment Co., Ltd., LINE Pay from LINE Corporation, and d Pay from NTT Docomo, Inc. Note that communication with the server of the payment agency or two-dimensional barcode payment institution may be performed via a communication unit (not shown) provided in the extension device 7 or the payment terminal 9.

[0036] The connection unit 99 connects the payment terminal 9 to other devices. The connection unit 99 particularly connects the payment terminal 9 to the expansion device 7, but may also be connected to the image forming device 3. For example, the connection unit 99 is a USB interface to which a USB memory or the like is connected. The connection unit 99 may also be an interface other than a USB interface, such as HDMI (registered trademark). Note that in FIG. 2, the connection units 45, 81, and 99 are connected in a so-called daisy chain configuration in which the connection units 45, 81, and 99 are connected in a straight line, but the present disclosure does not particularly limit the connection configuration, and the connection units 45, 81, and 99 may also be connected in a so-called star configuration with the connection unit 45 at the center.

[0037] [1.2 Operation of Payment System 1] The operation of the payment system 1 will be explained, focusing on the expansion device 7. The payment system 1 handles three types of payment processes (first payment process, second payment process, and cash payment process). Both the first payment process and the second payment process are cashless payments. The first payment process is executed by a first payment processing unit 80 provided (built-in) in the expansion device 7. The second payment process is executed by a second payment processing unit 98 of the payment terminal 9 connected (externally attached) to the expansion device 7. The cash payment process is executed by a cash payment processing unit 78 provided in the expansion device 7.

[0038] The payment system 1 executes either a first payment process or a second payment process, which are cashless payments. The decision as to which process to execute may be made, for example, by setting the operation settings of the extension device 7 on an operation settings screen (not shown) of the extension device 7 to indicate whether or not to execute each of the first and second payment processes. Alternatively, for example, the extension device 7 may detect whether or not a payment terminal 9 is connected to the connection unit 81, and may execute either the first or second payment process depending on the detection result. In this case, the extension device 7 executes the first payment process if connection of the payment terminal 9 to the connection unit 81 is not detected, and executes the second payment process if connection of the payment terminal 9 to the connection unit 81 is detected.

[0039] [1.2.1 Operation of payment system 1 (when first payment processing is executable)] FIG. 3 is a flowchart for explaining the operation of the extension device 7 of the payment system 1 according to the first embodiment of the present disclosure.

[0040] The control unit 71 accepts job settings via the operation unit 77 (step S1). Next, the control unit 71 displays a payment method selection screen on the display unit 75 (step S3). An example of the payment method selection screen is shown in FIG. 5(a). Details will be described later. When electronic money is selected on the payment method selection screen via the operation unit 77 (step S5, Yes), the control unit 71 displays an electronic money type selection screen on the display unit 75 (step S7). An example of the electronic money type selection screen is shown in FIG. 5(b). Details will be described later. The control unit 71 continues to display the electronic money type selection screen until the type of electronic money is selected on the electronic money type selection screen and the OK button is pressed (step S9, No). When the type (brand) of electronic money is selected on the electronic money type selection screen via the operation unit 77 and the OK button is pressed (step S9, Yes), the control unit 71 waits for the [Start] button on the payment method selection screen to be pressed (step S10, No). When the "Start" button on the payment method selection screen is operated via the operation unit 77 (step S10, Yes), the control unit 71 causes the first payment processing unit 80 to execute the payment process. The first payment processing unit 80 displays a payment screen on the display unit 75 and executes the payment process (step S11). An example of the payment screen is shown in FIG. 6(a). Details will be described later. If the payment process is successful (step S13, Yes), the control unit 71 displays a payment completion screen on the display unit 75 (step S15). An example of the payment completion screen is shown in FIG. 6(b). Details will be described later. After displaying the payment completion screen, the control unit 71 displays a job execution screen on the display unit 75 and requests the image forming apparatus 3 via the connection unit 81 to start a job in accordance with the settings accepted in step S1 (step S17). An example of the job execution screen is shown in FIG. 7(a). Details will be described later. In the image forming device 3, when a job start request is received from the extension device 7 via the connection unit 45, the control unit 31 executes the requested job. If the payment process fails (step S13, No), the control unit 71 returns the process to step S3.If electronic money is not selected in step S5 (cash payment is selected) (step S5, No), the control unit 71 causes the cash payment processing unit 78 to execute cash payment processing (step S19). After cash payment, the control unit 71 waits for the [Start] button on the payment method selection screen to be operated (step S21, No). When the [Start] button on the payment method selection screen is operated via the operation unit 77 (step S21, Yes), the control unit 71 requests the image forming device 3 via the connection unit 81 to start a job according to the settings accepted in step S1 (step S17). When the image forming device 3 receives a job start request from the extension device 7 via the connection unit 45, the control unit 31 executes the requested job.

[0042] The control unit 71 accepts job settings via the operation unit 77 (step S31). Next, the control unit 71 displays a payment method selection screen on the display unit 75 (step S33). An example of the payment method selection screen is illustrated in FIG. 7(b). Details will be described later. When cashless payment is selected on the payment method selection screen via the operation unit 77 (step S35, Yes), the control unit 71 waits for the "Start" button to be operated via the operation unit 77 (step S37, No). When the "Start" button is operated via the operation unit 77 (step S37, Yes), the control unit 71 displays a payment start screen on the display unit 75 (step S39). An example of the payment start screen is illustrated in FIG. 8(a). Details will be described later. When the "Yes" button is operated on the payment start screen via the operation unit 77, the control unit 71 displays a payment terminal guidance animation screen on the display unit 75 (step S41). An example of the payment terminal guidance animation screen is illustrated in FIG. 8(b). At this time, the control unit 71 also transmits a payment request to the payment terminal 9 via the connection unit 81, requesting that the payment process be executed.

[0043] When the payment terminal 9 receives the payment request via the connection unit 99, the control unit 91 causes the second payment processing unit 98 to execute the second payment processing. The control unit 91 then transmits a payment request response indicating the success or failure of the payment processing to the extension device 7 via the connection unit 99.

[0044] When a payment request response indicating successful payment is received from the payment terminal 9 via the connection unit 81 (step S43, Yes), the control unit 71 displays a job execution screen on the display unit 75 and requests the image forming device 3 via the connection unit 81 to start a job according to the settings accepted in step S31 (step S45). When the image forming device 3 receives a job start request from the extension device 7 via the connection unit 45, the control unit 31 executes the requested job. An example of the job execution screen is shown in FIG. 7(a). Details will be described later.

[0045] If cashless payment is not selected in step S35 (cash payment is selected) (step S35, No), the control unit 71 performs payment by cash (step S49). After cash payment, the control unit 71 waits for the [Start] button on the payment method selection screen to be operated (step S49, No). When the [Start] button on the payment method selection screen is operated via the operation unit 77 (step S49, Yes), the control unit 71 requests the image forming device 3 via the connection unit 81 to start a job according to the settings accepted in step S31 (step S45). When the image forming device 3 receives a job start request from the extension device 7 via the connection unit 45, the control unit 31 executes the requested job.

[0046] [1.3 Screen example] Figures 5(a), 5(b), 6(a), and 6(b), which will be described below, are examples of screens that are displayed on the display unit 75 when the first payment process shown in Figure 3 is executed.

[0080] [1.3.8 Payment terminal guidance animation screen 281] Payment terminal guidance animation screen 281 in FIG. 8(b) is an example of a payment terminal guidance animation screen. Payment terminal guidance animation screen 281 is a screen for guiding a user who is operating operation unit 77 while looking at display unit 75 of extension device 7 to payment terminal 9. Payment terminal guidance animation screen 281 is a moving image that is displayed repeatedly to attract the user's attention and more reliably guide the user to payment terminal 9. Payment terminal guidance animation screen 281 may be any moving image as long as it can achieve the purpose of guiding the user to payment terminal 9. The following explanation is merely an example of payment terminal guidance animation screen 281.

[0081] Payment terminal guidance animation screen 281 has an extension device image 283, a payment terminal image 285, and a message display 287. In payment terminal guidance animation screen 281, the portion of payment terminal image 285 that corresponds to display unit 95 of payment terminal 9 blinks repeatedly to guide the user to payment terminal 9. Alternatively, an arrow image (not shown) pointing to payment terminal image 285 may be displayed in payment terminal guidance animation screen 281, and the arrow image may be blinked repeatedly. Message display 287 is a message display that guides the user to perform an operation on payment terminal 9. Message display 287 displays the message, "Please continue the operation at the payment terminal on the left side of the main unit."

[0082] [1.4 Effects] According to the first embodiment, the payment processing is performed by a payment processing unit provided in the extended device, so in the first payment processing, which does not require the user to be guided to the payment terminal, the payment terminal guidance animation screen is not displayed, but in the second payment processing, which requires the user to be guided to the payment terminal, the payment processing is performed by a payment processing unit provided in an external payment terminal, so when the situation arises where payment is to be made using the payment terminal, the payment terminal guidance animation screen is displayed on the display unit of the extended device, so that regardless of which payment processing is performed, the user can perform operations related to the payment processing smoothly and without confusion.

[0083] [2. Second Embodiment] The second embodiment will be described. Compared to the first embodiment, the second embodiment differs from the first embodiment in the processing performed when the second payment process is performed, after the payment terminal guidance animation screen is displayed on the display unit 75 of the extension device 7. Steps S31 to S49 in FIG. 4 are the same as those in the first embodiment, and therefore will not be described here.

[0084] Fig. 9 is the first half of a flowchart for explaining the operation of the extension device 7 of the payment system 1 according to the second embodiment of the present disclosure. Fig. 10 is the second half of a flowchart for explaining the operation of the extension device 7 of the payment system 1 according to the second embodiment of the present disclosure.

[0085] In step S41, the control unit 71 displays a payment terminal guidance animation screen on the display unit 75 and instructs the payment terminal 9 to execute the payment process, and then sends a brightness change request to the payment terminal 9 via the connection unit 81, requesting that the brightness of the display unit 95 be increased (step S51).

[0086] When the payment terminal 9 receives a brightness change request via the connection unit 99, the control unit 91 increases the brightness of the display unit 95, and returns the brightness of the display unit 95 to its original state when an operation is received via the operation unit 97. In this way, increasing the brightness of the display unit 95 of the payment terminal 9 more reliably guides the user to the payment terminal 9. Thereafter, the control unit 91 executes the payment process based on input and output using the display unit 95 and the operation unit 97. Regardless of the success or failure of the payment process, the control unit 91 transmits a payment result notification to the expansion device 7 via the connection unit 99 to notify the expansion device 7 of the success or failure of the payment.

[0087] Returning to the extension device 7, the control unit 71 waits to receive a payment result notification from the payment terminal 9 (step S53, No), and upon receiving the payment result notification via the connection unit 81 (step S53, Yes), the control unit 71 increases the brightness of the display unit 75 (step S57). This guides the user who has been operating the payment terminal 9 to make a payment to the extension device 7.

[0088] The control unit 71 waits until some operation is performed on the operation unit 77 (step S59, No), and when some operation is detected (step S59, Yes), it returns the brightness of the display unit 75 to the original level (step S61).

[0089] 11A and 11B are schematic diagrams illustrating the operation of the payment system 1 according to the second embodiment of the present disclosure, and Fig. 11A is a schematic diagram illustrating the control of the light-emitting state of the display unit of the payment terminal. Fig. 11A shows a schematic diagram of the state in which the control unit 91 increases the brightness of the display unit 95 in the payment terminal 9 after receiving a brightness change request from the extension device 7 in step S51, as brightness increase 301.

[0090] 11(b) is a schematic diagram illustrating the control of the light-emitting state of the display unit of the expansion device. In FIG. 11(b), the control unit 71 of the expansion device 7, which has received a payment result notification from the payment terminal 9, increases the brightness of the display unit 75 in step S57, as shown as brightness increase 303.

[0091] 2.1 Modification of the second embodiment In the second embodiment described above, the user is guided by increasing the brightness of the display unit 95 of the payment terminal 9 and the display unit 75 of the expansion device 7, but instead of increasing the brightness of the display units 75, 95, the display units 75, 95 may be made to blink.

[0092] In the second embodiment, the user is guided by increasing the brightness of the display units 75, 95, and in the modified second embodiment, the display units 75, 95 are blinking, but the user may also be guided by using the light-emitting state of the display units 75, 95 in a manner other than increasing the brightness or blinking. For example, the light-emitting state of the display units 75, 95 may be repeatedly changed between zero brightness and maximum brightness by combining a change in brightness and blinking.

[0093] [2.2 Effects of the second embodiment and its modifications] According to the second embodiment and its variations, when an operation on the payment terminal becomes necessary, the brightness of the display unit of the payment terminal is increased or the display unit is made to blink, thereby guiding the user to the payment terminal, and conversely, when an operation on the expansion device becomes necessary, the brightness of the display unit of the expansion device is increased or the display unit is made to blink, thereby guiding the user to the expansion device. Therefore, according to the second embodiment, it is possible to more effectively guide the user to the device that requires operation at the necessary timing.

[0094] 3. Third Embodiment A third embodiment will now be described. Compared to the first embodiment, in the third embodiment, an extension device 7A is used instead of the extension device 7, and a payment terminal 9A is used instead of the payment terminal 9. In the second embodiment, the light emission state of the display units 75 and 95 was changed to guide the user, but in the third embodiment, a voice message is output from the voice output units 315 and 319 to guide the user.

[0095] 12 is a functional block diagram of a payment system 1A according to a third embodiment of the present disclosure. In payment system 1A, extension device 7A and payment terminal 9A are equipped with audio output units 315 and 319, respectively. Audio output units 315 and 319 may be built into extension device 7A and payment terminal 9A, respectively, or may be external devices attached via connectors 81 and 99 of extension device 7A and payment terminal 9A, respectively.

[0096] Fig. 13 is the first half of a flowchart for explaining the operation of the extension device 7A of the payment system 1A according to the third embodiment of the present disclosure. Fig. 14 is the second half of a flowchart for explaining the operation of the extension device 7A of the payment system 1A according to the third embodiment of the present disclosure. Steps S31 to S49 are the same as those in the first embodiment, so their explanation will be omitted.

[0097] In step S41, the control unit 71 displays a payment terminal guidance animation screen on the display unit 75, transmits a payment request to the payment terminal 9A, and then outputs a voice message from the voice output unit 315 (S71). This voice message is intended to guide the user from the extension device 7A to the payment terminal 9A.

[0098] The control unit 71 waits until it receives an input notification from the payment terminal 9A via the connection unit 81 (step S73, No). Here, the input notification from the payment terminal 9A is a signal that the control unit 91 transmits to the expansion device 7A via the connection unit 99 in accordance with the content of the operation when the operation unit 97 accepts some operation. When the control unit 71 receives the input notification from the payment terminal 9A (step S73, Yes), it stops outputting the voice message from the voice output unit 315 (S75).

[0099] Next, the control unit 71 waits until it receives a payment result notification via the connection unit 81 (step S76, No). The payment result notification is a notification regarding the result of the payment process executed by the control unit 91 based on the user's operation on the operation unit 97 in the payment terminal 9A, which has received a payment request from the expansion device 7A via the connection unit 99. Upon receiving the payment result notification (step S76, Yes), the control unit 71 sends a voice message output request to the payment terminal 9A (step S77). Upon receiving the voice message output request via the connection unit 99, the payment terminal 9A outputs a voice message from the voice output unit 319 in response to the voice message output request. This voice message is intended to guide the user from the payment terminal 9A to the expansion device 7A.

[0100] After step S77, control unit 71 waits to receive a notification regarding the operation performed by the user on operation unit 77 via connection unit 81 (step S79, No), and upon receiving the notification (step S79, Yes), transmits a voice message output stop request to payment terminal 9A via connection unit 81 to request that the output of the voice message be stopped (step S81). Upon receiving the voice message output stop request via connection unit 99, control unit 91 in payment terminal 9A stops the output of the voice message from voice output unit 319.

[0101] 15A and 15B are schematic diagrams illustrating the operation of payment system 1A according to the third embodiment of the present disclosure, and Fig. 15A is a schematic diagram illustrating the manner in which extension device 7A outputs a voice message guiding payment terminal 9A. Fig. 15A illustrates the manner in which control unit 71 outputs voice message 331 from voice output unit 315 of extension device 7A in step S71.

[0102] Fig. 15(b) is a schematic diagram illustrating how the payment terminal 9A outputs a voice message guiding the extension device 7A. Fig. 15(b) is a schematic diagram illustrating how the control unit 91 of the payment terminal 9A outputs a voice message from the voice output unit 319 in response to the voice message output request sent by the control unit 71 in step S77.

[0103] As described above, according to the third embodiment, when an operation on the payment terminal 9A becomes necessary, a voice message is output from the voice output unit 315 of the extension device 7A to guide the user to the payment terminal 9A. Also, when an operation on the extension device 7A becomes necessary, a voice message is output from the voice output unit 319 of the payment terminal 9A to guide the user to the extension device 7A. Therefore, according to the third embodiment, the user can be more effectively guided to a device that requires operation at the necessary timing.

[0104] [4. Fourth Embodiment] A fourth embodiment will now be described. In the first embodiment, in step S41, a payment terminal guidance animation screen is displayed on the display unit 75 to guide the user to the payment terminal 9. In the fourth embodiment, if an operation unit other than the operation unit of a device that requires operation is operated among the multiple operation units 37, 77, 97 provided in the payment system 1, a message is displayed on the display unit corresponding to the operation unit that was operated by mistake. This message is intended to guide the user to the device that requires operation.

[0105] Specifically, suppose that the operation unit 37, 77 of the image forming device 3 or the expansion device 7 is operated in a situation where operation is required on the operation unit 97 of the payment terminal 9. In this case, for example, a message saying "Please operate using the operation panel on the left (leftmost)" is displayed on the display unit 35, 75 of the image forming device 3 or the expansion device 7. Also, suppose that the operation unit 37, 97 of the image forming device 3 or the payment terminal 9 is operated in a situation where operation is required on the operation unit 77 of the expansion device 7. In this case, for example, a message saying "Please operate using the center operation panel" is displayed on the display unit 35, 95 of the image forming device 3 or the payment terminal 9. Note that in this embodiment, operation on the image forming device 3 is not required, and therefore a situation where operation on the operation unit 37 is required does not occur.

[0106] FIG. 16 is a schematic diagram illustrating the operation of payment system 1 according to the fourth embodiment of the present disclosure, and FIG. 16(a) is a schematic diagram illustrating the image forming device 3 and the extension device 7 displaying messages 351 and 353 guiding the user to payment terminal 9. In step S41 of FIG. 4, control unit 31 displays message 351 on display unit 75 and message 353 on display unit 35 instead of the payment terminal guidance animation screen. Messages 351 and 353 are text messages saying, "Please operate using the panel on the left." Here, the "left panel" refers to the display unit on the left side as seen by the user, i.e., display unit 95.

[0107] FIG. 16(b) is a schematic diagram illustrating how the payment terminal and image forming apparatus display messages 357 and 359 to guide the user to the expansion device. In step S45 of FIG. 4, control unit 31 displays a job execution screen on display unit 75 and starts the job, and also displays message 359 on display unit 35. In the same step, control unit 31 also transmits a message display request to payment terminal 9 via connection unit 45, requesting the display of a message. In payment terminal 9, when connection unit 99 receives the message display request, control unit 91 displays message 357 on display unit 95. Messages 357 and 359 are text messages saying, "Please operate on the center panel." Here, the "center panel" refers to the display unit in the middle of the three display units 35, 75, and 95 as seen from the user, i.e., display unit 75.

[0108] Although messages 351, 353, 357, and 359 have been described as text messages, the form of these messages does not have to be text messages. For example, animated screens such as animated screens guiding the payment terminal may be used. Still images such as illustrations or photographs representing the destination devices may also be used.

[0109] According to the fourth embodiment, a message guiding the user is displayed on the display unit 75 of the extension device 7A, the display unit 95 of the payment terminal 9A, and also on the display unit 35 of the image forming device 3. Therefore, according to the fifth embodiment, the user can be reliably guided to a device that requires operation at the required timing.

[0110] [5. Fifth Embodiment] A fifth embodiment will now be described. In the fifth embodiment, after the execution of a job is completed, specifically after step S17 in Fig. 3 or step S45 in Fig. 4, Fig. 10, or Fig. 14 is executed, a lost item prevention screen is displayed on the display unit 75. In the fifth embodiment, the type of job executed in step S17 or S45 is determined, and a lost item prevention screen corresponding to that type is displayed.

[0111] A user may obtain a copy of a resident registration certificate or a seal registration certificate by using a government service through the payment system 1. Items that a user who has used a government service may leave behind at the payment system 1 include the My Number card used to use the government service, various documents obtained by using the government service, change from a cash payment, various cards and smartphones used in a cashless payment, etc. When using a government service, there is no original document that the user needs to prepare, such as a photocopy.

[0112] Therefore, when a job related to an administrative service is executed in step S17 or S45, the control unit 71 displays a lost property prevention screen 371 on the display unit 75.

[0113] 17A and 17B show examples of screens displayed on the extension device 7 of the payment system 1 according to the fifth embodiment of the present disclosure, and the lost property prevention screen 371 in Fig. 17A is an example of a screen displayed after using a government service. The lost property prevention screen 371 includes a message 373 and illustrations 375, 377, 379, and 381.

[0114] Message 373 is a message that warns the user not to leave anything behind, and here it says "Please be careful not to leave anything behind." Illustration 375 shows a receipt. Illustration 377 shows cards such as a My Number card. Illustration 379 shows change. Illustration 381 shows printed matter, here a copy of a resident registration card, a seal registration certificate, etc.

[0115] On the other hand, there are cases where a user uses a copy service in the payment system 1. In this case, items that the user leaves behind at the payment system 1 include receipts, change, manuscripts, printed materials, various cards used in cashless payments, smartphones, etc.

[0116] Therefore, when a job related to the copy service is executed in step S17 or S45, the control unit 71 displays a lost item prevention screen 391 on the display unit 75. The lost item prevention screen 391 in Fig. 17(b) is an example of a screen displayed after using the copy service. The lost item prevention screen 391 includes illustrations 375, 379, 381, and 385. Illustration 385 shows a document.

[0117] When using a copy service, there is a possibility that the original to be copied will be left behind. For this reason, the loss prevention screen 391 includes illustration 385 showing the original. Also, since My Number cards are not usually used in copy services, there is no risk of the My Number card being left behind. For this reason, the loss prevention screen 391 does not include illustration 377 showing cards. Note that when cashless payment is made, an IC card is used, so it is preferable that the loss prevention screen 391 also includes illustration 377 showing cards. In this case, no change is given, so it is preferable that the loss prevention screen 391 be displayed without illustration 379 showing change.

[0118] According to the fifth embodiment, a different forgetting prevention screen is displayed depending on the type of job executed, so that it is possible to call attention to prevent forgetting depending on the type of job executed.

[0119] [6. Sixth Embodiment] A sixth embodiment will now be described. As in the fifth embodiment, in the sixth embodiment, after the execution of a job is completed, specifically after step S17 in Fig. 3 and step S45 in Figs. 4, 10, and 14 are executed, a lost item prevention screen is displayed on the display unit 75. In the fifth embodiment, a lost item prevention screen corresponding to the type of job is displayed, but in the sixth embodiment, a lost item prevention screen corresponding to the payment method used is displayed.

[0120] When paying in cash, there is a risk of forgetting to give change. On the other hand, when paying in cashless mode, there is no risk of forgetting to give change, but there is a risk of forgetting the credit card or smartphone used for the cashless payment. In consideration of this, in the sixth embodiment, a forget prevention screen is displayed according to the payment method.

[0121] 18A and 18B show examples of screens displayed on the extension device 7 of the payment system 1 according to the sixth embodiment of the present disclosure, and the lost item prevention screen 401 in FIG. 18A is an example of a screen displayed when payment is made by cash. In the first payment process of FIG. 3, if cash payment is selected in step S5, the control unit 71 displays the lost item prevention screen 401 on the display unit 75 after the job started in step S17 is completed. Also, in the second payment process of FIG. 4, if cash payment is selected in step S35, the lost item prevention screen 401 is displayed.

[0122] The lost item prevention screen 401 includes a message 373 and illustrations 375, 379, and 381. When paying in cash, change may be required, so the lost item prevention screen 401 includes an illustration 379 showing change.

[0123] The lost item prevention screen 411 in Figure 18(b) is an example of a screen that is displayed when a cashless payment is made. In the second payment process of Figures 4, 9, and 13, if cashless payment (electronic money payment) is selected in step S35, the control unit 71 displays the lost item prevention screen 411 after the job started in step S45 is completed. Also, in the first payment process of Figure 3, if electronic money payment is selected in step S5, the lost item prevention screen 411 is displayed.

[0124] Lost item prevention screen 411 includes message 373, illustrations 375, 377, 381, and message 413. Because cashless payment (electronic money payment) does not require change, lost item prevention screen 411 does not include illustration 379 showing change. Instead, cashless payment (electronic money payment) may require the use of a credit card or smartphone. For this reason, lost item prevention screen 411 includes illustration 377 showing cards and message 413 warning the user not to forget their smartphone.

[0125] According to the sixth embodiment, a different forgetting prevention screen is displayed depending on the payment method used, so that it is possible to call attention to preventing forgetting according to the payment method.

[0126] [7. Variations] The present disclosure is not limited to the above-described embodiments and variations, and various modifications are possible. In other words, embodiments obtained by combining appropriately modified technical means within the scope of the gist of the present disclosure are also included in the technical scope of the present disclosure.

[0127] It will be clear to those skilled in the art that the first to sixth embodiments described above can be combined and implemented. For example, in the second embodiment, the user is guided by changing the brightness of the display unit of the payment terminal, and in the third embodiment, the user is guided by outputting a voice message. However, it is possible to perform both of these user guidance methods. Furthermore, while the fifth and sixth embodiments have been described as displaying a lost item prevention screen based on the first embodiment, it is also possible to display a lost item prevention screen based on the second, third, or fourth embodiment.

[0128] In addition to displaying the payment terminal guidance screen, in the second embodiment and its variations, the user is guided by changing the brightness or blinking of the display unit. In the third embodiment, the user is guided by outputting a voice message. The execution of such output to guide the user to the payment terminal does not necessarily have to be performed after the display of the payment terminal guidance screen. The change in brightness or blinking of the display unit or the output of the voice message may be performed simultaneously with the display of the payment terminal guidance screen, or may be performed after the display of the payment terminal guidance screen.

[0129] In the first embodiment, electronic money payment is used as a payment method other than cash. However, the present invention is not limited to this, and cashless payment other than electronic money payment may also be used. For example, smartphone payment, credit card payment, or debit card payment may be used. Smartphone payment is a payment method in which payment is made using a dedicated payment app downloaded to a smartphone. Credit card payment is a payment method in which payment is made by inserting or holding a credit card over a dedicated terminal at a store's cash register, or by entering the credit card number, expiration date, etc. on a payment screen on a website. Debit card payment is a payment method in which payment is made using a card, similar to a credit card, and the amount used is immediately debited from a bank account after payment.

[0130] In the fifth embodiment, the description has been given assuming that the lost-item prevention screens 371 and 391 in FIGS. 17(a) and 17(b) are displayed. However, other lost-item prevention screens may be displayed depending on the service usage status (user operations and operations of the image forming device 3, the extension device 7, and the payment terminal 9) in the payment system 1. For example, if the user does not perform an operation to print a receipt, the lost-item prevention screens 371 and 391 may be displayed without the illustration 375 depicting the receipt. Furthermore, if cash payment is selected, the lost-item prevention screens 371 and 391 may be displayed as they are, whereas if cashless payment is selected, the lost-item prevention screens 371 and 391 may be displayed without the illustration 379 depicting the change.

[0131] In the sixth embodiment, the description has been given assuming that the lost item prevention screens 401 and 411 in Figures 18(a) and 18(b) are displayed, but other lost item prevention screens may be displayed depending on the usage status of the services in the payment system 1 (user operations and the operations of the image forming device 3, the extension device 7, and the payment terminal 9). For example, if the user does not perform an operation to print a receipt, the lost item prevention screens 401 and 411 may be displayed excluding the illustration 375 showing the receipt.

[0132] In the above embodiment, the image forming device 3 and the extension device 7 are described as separate devices, but the image forming device 3 may be configured as an integrated unit with the extension device 7. In this case, the image forming device 3 further includes a cash payment processing unit 78, an IC card reading and writing unit 79, and a first payment processing unit 80. In addition, the control unit 31, memory unit 33, display unit 35, operation unit 37, and connection unit 45 of the image forming device 3 also operate as the control unit 71, memory unit 73, display unit 75, operation unit 77, and connection unit 81 of the extension device 7, respectively.

[0133] In the first embodiment, the payment system 1 is described as being capable of executing only one of the first and second cashless payment processes. However, both may be executable. For example, the title "Electronic Money" in the upper left corner of the electronic money selection screen 151 in FIG. 5(b) is changed to "Cashless Payment," and the button 155 is changed to a "Two-dimensional Code Payment" button. In response to an operation to select the button 155, the second payment processing unit 98 displays available two-dimensional code payment methods (e.g., PayPay from PayPay Corporation, Rakuten Pay from Rakuten Payment Co., Ltd., LINE Pay from LINE Corporation, d Pay from NTT Docomo, Inc., etc.) in the display field 160. When the button 155 is selected and the OK button 167 is operated after the type of two-dimensional code payment to be used is selected, steps S39, S41, S43, and S45 in FIG. 4 are executed.
