Description

[Technical Field]

[0001] The present invention relates to an image recording apparatus and a consumables ordering processing program. [Background technology]

[0002] Conventionally, an automatic ordering system for consumables, such as that described in Patent Document 1, is known. In this conventional technology, the degree of consumption of consumables such as ink and recording media is transmitted from the image recording device to a management server. When the consumption state amount, which indicates the degree of consumption, reaches a predetermined threshold, the management server transmits an order request to a retail store server, and the retail store server that receives the order request dispatches the consumables to the user.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-136638 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional technology described in Patent Document 1, consumables are delivered to the user one after another each time the consumption state amount of each consumable item held by the image recording device reaches the corresponding threshold, which makes it time-consuming and burdensome for the user to receive and manage the items.

[0005] An object of the present invention is to provide an image recording device and a consumables ordering processing program that can reduce the burden on the user by enabling multiple consumables to be ordered simultaneously. [Means for solving the problem]

[0006] In order to achieve the above object, an image recording device of the present invention includes an image recording unit that records an image on a recording medium, at least two consumables including a first consumable and a second consumable, and a control unit, wherein the control unit performs a first determination process to determine whether a degree of consumption of the first consumable falls into one of a first state, a second state that is more consumed than the first state, and a third state that is more consumed than the second state, a second determination process to determine whether a degree of consumption of the second consumable falls into one of a fourth state, a fifth state that is more consumed than the fourth state, and a sixth state that is more consumed than the fifth state, and a control unit to execute a first determination process to execute a second determination process to execute a sixth ... and an order selection process for selectively performing an ordering process or a non-ordering process for the first consumable and the second consumable when the first consumable reaches the third state before the second consumable reaches the sixth state based on the judgment results of the second judgment process and the second judgment process, wherein the order selection process includes a first process for performing the ordering process for the first consumable and the non-ordering process for the second consumable when the second consumable is in the fourth state, and a second process for performing the ordering process for the first consumable and the ordering process for the second consumable when the second consumable is in the fifth state.

[0007] In the image recording device of the present invention, when a consumable item is consumed and needs to be ordered, the control unit executes a first determination process and a second determination process so that multiple consumable items that are nearly consumed to a certain extent are ordered at the same time.

[0008] In the first determination process, in order to distinguish the progress of consumption of the first consumable item by dividing it into three states, it is determined whether the degree of consumption of the first consumable item corresponds to a first state, a second state, or a third state. In the second determination process, in order to distinguish the progress of consumption of the second consumable item by dividing it into three states, it is determined whether the degree of consumption of the second consumable item corresponds to a fourth state, a fifth state, or a sixth state.

[0009] As the first consumable is consumed, it changes state in the order of first state → second state → third state, and as the second consumable is consumed, it changes state in the order of fourth state → fifth state → sixth state. If the first consumable is consumed faster than the second consumable and the first consumable reaches the third state before the second consumable reaches the sixth state, the control unit executes an order selection process.

[0010] In the order selection process, ordering or non-ordering is selectively performed for the first consumable and the second consumable. If the second consumable is still in the fourth state when the first consumable reaches the third state, ordering is performed only for the first consumable in the first process, and non-ordering is performed for the second consumable. If the second consumable has reached the fifth state when the first consumable reaches the third state, ordering is performed for the first consumable in the second process, and ordering is also performed for the second consumable.

[0011] According to the present invention, even if the degrees of consumption of the first consumable and the second consumable do not match, if the second consumable has also been consumed to a certain extent by the time the first consumable becomes heavily consumed and ordering processing is performed, ordering processing for the second consumable is also performed. Since the first consumable and the second consumable can be ordered and delivered at the same time, the burden on the user can be reduced compared to when the second consumable is delivered at a different time after the first consumable is delivered.

[0012] In order to achieve the above object, an image recording device of the present invention includes an image recording unit that records an image on a recording medium, at least two consumables including a first consumable and a second consumable, a display, and a control unit, wherein the control unit performs a first determination process that determines whether a degree of consumption of the first consumable falls into one of a first state, a second state that is more consumed than the first state, and a third state that is more consumed than the second state, a second determination process that determines whether a degree of consumption of the second consumable falls into one of a fourth state, a fifth state that is more consumed than the fourth state, and a sixth state that is more consumed than the fifth state, and a control unit that performs a first determination process and a second determination process. and a first display selection process is executed to selectively perform a display process or a non-display process on the order screen of the display for the first consumable and the second consumable when the first consumable reaches the third state before the second consumable reaches the sixth state based on the judgment result of the second judgment process, and the first display selection process includes a third process to perform the display process for the first consumable and the non-display process for the second consumable when the second consumable is in the fourth state, and a fourth process to perform the display process for the first consumable and the display process for the second consumable when the second consumable is in the fifth state.

[0013] Furthermore, in order to achieve the above object, the image recording device of the present invention comprises an image recording unit that records an image on a recording medium, at least two consumables including a first consumable that is a cartridge and a second consumable other than a cartridge, a display, and a control unit, wherein the control unit performs a first determination process that determines whether the degree of consumption of the first consumable falls into one of a first state, a second state that is more consumed than the first state, and a third state that is more consumed than the second state, a third determination process that determines whether the degree of consumption of the second consumable falls into one of a fourth state and a fifth state that is more consumed than the fourth state, and a second display selection process that displays an order screen on the display when the first consumable falls into the third state based on the determination results of the first determination process and the third determination process, and selectively performs a display process or a non-display process for the first consumable and the second consumable on the order screen. The second display selection process includes a fifth process of performing the display process related to the first consumable, including displaying identification information of the first consumable and a first object indicating the consumption state of the first consumable, and a sixth process of performing the display process related to the second consumable, including displaying identification information of the second consumable and a second object indicating the consumption state of the second consumable. [Effects of the Invention]

[0014] According to the present invention, the burden on the user can be reduced by making it possible to order multiple consumables at the same time. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] A print processing system according to one embodiment of the present invention is shown in Fig. 1. This embodiment is an embodiment of a print processing system 1 that can provide a delivery service based on an ordering contract in which replacement consumables are automatically ordered when consumables used in a multifunction peripheral 200 have been consumed to a certain extent.

[0017] <Outline of the printing processing system> 1, the print processing system 1 includes an information management server 100, a multifunction peripheral 200, a mobile terminal 300, and a delivery management server 400. The information management server 100, the multifunction peripheral 200, the mobile terminal 300, and the delivery management server 400 are connected to a network NT and can communicate with each other. The multifunction peripheral 200 is an example of an image recording device.

[0018] <Information management server> The information management server 100 is a server installed and managed by, for example, the manufacturer of the multifunction peripheral 200, and includes a processor 110, a storage device 115, and an interface 190. The processor 110, the storage device 115, and the interface 190 are connected to one another via a bus 105.

[0019] The storage device 115 includes a volatile storage device 120 and a nonvolatile storage device 130. The volatile storage device 120 is, for example, a DRAM, and temporarily stores various types of data. The nonvolatile storage device 130 is, for example, a hard disk drive or a solid state drive, and includes a program storage area 131 and a data storage area (not shown).

[0020] The processor 110 is a device that performs data processing, such as a CPU. The processor 110 executes programs stored in the program storage area 131 to perform various processes, including data communication with the mobile terminal 300, the multifunction peripheral 200, and the delivery management server 400 connected to the network NT.

[0021] The interface 190 is a wired LAN interface or a wireless interface for communicating with other devices, and is connected to the network NT.

[0022] <Delivery management server> The delivery management server 400 is installed in, for example, a company that provides delivery services for various items, and has a processor, a storage device, and an interface for connecting to the network NT (not shown).

[0023] <Multifunction device> The multifunction device 200 is owned, for example, by a business that provides the printing service. The multifunction device 200 may also be personally owned by the user. The multifunction device 200 includes an interface 270, a processor 210, a printing unit 290, a consumption detection sensor 285, a scanner unit 280, a cartridge holder 51, an ink level sensor 52, a storage device 215, a display unit 240, and an operation unit 250. The interface 270, processor 210, printing unit 290, consumption detection sensor 285, scanner unit 280, ink level sensor 52, storage device 215, display unit 240, and operation unit 250 are connected to one another via a bus 205.

[0024] The storage device 215 includes a volatile storage device 220 and a nonvolatile storage device 230. The volatile storage device 220 is, for example, a DRAM, and temporarily stores various data. The nonvolatile storage device 230 is, for example, a flash memory. The nonvolatile storage device 230 includes a replacement consumables list 231, an ordered consumables list 232, and a program storage area 233. The program storage area 233 stores various programs, including a consumables ordering processing program of this embodiment that is involved in executing flowcharts such as those shown in Figures 4 and 7, which will be described later. This consumables ordering processing program is stored in advance in the program storage area 233 as firmware, for example. The nonvolatile storage device 230 also stores a wear level determination table (not shown). This wear level determination table, the replacement consumables list 231, and the ordered consumables list 232 will be described later.

[0025] The processor 210 is a device that performs various processes, and is, for example, a CPU. The processor 210 is an example of a control unit. The processor 210 executes the consumables order processing program stored in the program storage area 233.

[0026] The display unit 240 is, for example, a liquid crystal display. The operation unit 250 is a device that accepts operations by the user. The user can input various instructions to the multifunction device 200 by operating the operation unit 250. The communication interface 270 is a wired or wireless network interface for communicating with other devices, and is connected to the network NT.

[0027] The scanner unit 280 optically reads an original document, which is an object to be read, using a photoelectric conversion element such as a CCD or CMOS, and generates scan data representing the read image.

[0028] The printing unit 290 prints an image on the transported paper using a predetermined method while removing and transporting paper from a paper feed tray using a transport mechanism (not shown). The following description will be given taking an example of inkjet printing. Specifically, the printing unit 290 forms an image on paper using ink from ink cartridges 50 removably mounted in a cartridge holder 51. Paper is an example of a recording medium. The ink cartridges 50 include ink cartridges 50 for yellow ink (Y), magenta ink (M), cyan ink (C), and black ink (BK). For convenience, however, the following description will refer to them simply as "ink cartridges 50" without distinguishing between them unless otherwise specified. The remaining ink level sensor 52 is a sensor that individually detects the remaining ink in each of the multiple ink cartridges 50, which are consumables.

[0029] The printing unit 290 includes consumables among its constituent parts that, like the ink cartridge 50, wear out as a result of repeated image printing or deteriorate over time and require replacement. In the case of the inkjet printing unit 290 in this example, there are, for example, a waste liquid tank that stores used ink, a recording head made up of an ink head that sprays ink onto paper when printing, and a cutter that cuts the paper (not shown). The paper itself is also a type of consumable. The consumption detection sensor 285 provided in this embodiment is a collection of sensors that individually detect the consumption state of each of these various consumables for the printing unit 290. The printing unit 290 is an example of an image recording unit.

[0030] <Mobile device> The mobile terminal 300 is a mobile terminal such as a smartphone owned by a user, and is connected to the network NT via wireless communication. The mobile terminal 300 has a processor, a storage device, and an interface for connecting to the network NT (not shown). Various programs are stored in a program storage area provided in the storage device. Note that instead of the mobile terminal 300, other information terminals such as a personal computer or a tablet computer may be used.

[0031] <Regarding ordering consumables for multifunction printers> In the print processing system 1 configured as above, the present embodiment is characterized by a process of automatically ordering replacement consumables when consumables in the multifunction peripheral 200 are used up and need to be replaced.

[0032] Therefore, the multifunction device 200 uses the remaining ink sensor 52 and wear detection sensor 285 to sequentially detect and monitor the wear level of each of the consumables in this example, the ink cartridges 50 of each color, the waste liquid tank, the recording head, the cutter, and the paper. At this time, the need to replace each consumable is determined by referring to a wear level determination table such as that shown in Figure 2. In the example shown in Figure 2, the wear level determination table records the name of the consumable and an index of wear level, which is divided into three levels, in association with each identification number of all consumables (No. 1 to 7 in the example shown).

[0033] The indicators of the degree of wear are first normalized by dividing the detection value (signal value) of each sensor, namely the ink remaining sensor 52 and the wear detection sensor 285, into ten equal parts, based on the sensor detection value range from a brand new state immediately after replacement to the maximum wear state according to specifications. The indicators are then divided into three stages, each divided into ten equal parts: a low wear state, which is considered to be in a state close to new; a high wear state, which is considered to require replacement; and a medium wear state, which is considered to be in between. Because the rate at which consumables are consumed varies greatly depending on the type of consumable, different ten-part unit ranges correspond to each level of wear. In other words, consumables that are consumed quickly, such as the ink cartridge 50, are considered to be at a high wear state, requiring replacement, even when they are at a relatively low wear state. Consumables that are consumed slowly, such as the print head, are considered to be at a medium wear state, even when they are at a relatively high wear state. Specifically, for each type of consumable, a small-medium threshold corresponding to the boundary between low and medium levels of consumption and a medium-large threshold corresponding to the boundary between medium and high levels of consumption are recorded in advance, using the sensor detection value corresponding to the corresponding type of consumable as a reference, and the level of consumption is determined by comparing the actually detected sensor detection value with each threshold.

[0034] As described above, it would be extremely convenient for the user if the multifunction device 200 itself could determine the wear level of each consumable item stored therein and automatically order replacement consumable items when it determines that replacement is necessary. However, since the multifunction device 200 has a large number of consumable items, if an order were to be placed each time a replacement was determined to be necessary, consumable items would be delivered to the user one after another, which would be time-consuming and burdensome for the user to receive and manage.

[0035] In contrast, in the multifunction device 200 of this embodiment, when consumables become depleted and need to be reordered, ordering processes are performed at the same time for multiple consumables that are nearly identical in degree of depletion. For example, as shown in Figure 3(a), which considers only two ink cartridges 1 and 2 for ease of understanding, if one ink cartridge 1 reaches a high depletion state while the other ink cartridge 2 is still in a low depletion state, only ink cartridge 1 is ordered. However, as shown in Figure 3(b), if one ink cartridge 1 reaches a high depletion state while the other ink cartridge 2 is in a medium depletion state, both ink cartridges 1 and 2 are ordered.

[0036] In this way, even if the degrees of consumption of two consumables do not match, if one consumable has become significantly consumed and the other consumable has also become somewhat consumed by the time the ordering process is performed, the ordering process for the other consumable will also be performed. This allows multiple consumables with relatively similar degrees of consumption to be ordered and delivered at the same time, reducing the burden on the user compared to when they are delivered at different times.

[0037] Even if a specific consumable is still in a low-level of wear and tear state, like new, and a replacement is ordered and delivered early, the user will have to take the time and effort to manage the replacement consumable for a long time until it is actually replaced, which will be a significant burden. Therefore, the above-mentioned low-medium threshold, which corresponds to the boundary between low and medium levels of wear and tear, must also be set appropriately, taking into account the wear rate of the consumable.

[0038] In this embodiment, in order to prevent duplicate ordering of consumables that have already been ordered, consumables determined to need replacement and consumables that have already been ordered are managed separately. Specifically, consumables with a high level of consumption determined to need immediate ordering based on the most recently detected sensor detection value and consumables with a medium level of consumption determined to be ordered at the same time are all recorded in a replacement consumables list 231. Furthermore, consumables that have already been ordered but have not yet been replaced at that time are recorded in an ordered consumables list 232 based on past order and replacement histories. Among the consumables recorded in the replacement consumables list 231, consumables recorded in the ordered consumables list 232 that are also recorded are deleted from the replacement consumables list 231 as having already been ordered, and only the remaining consumables are actually ordered, thereby preventing duplicate ordering. This is particularly useful when it takes a considerable amount of time from when a consumable is actually ordered until it is delivered to the user and becomes available for replacement.

[0039] In the above example, ink cartridge 1 is an example of the first consumable item, ink cartridge 2 is an example of the second consumable item, the low depletion state, medium depletion state, and high depletion state of ink cartridge 1 are examples of the first state, second state, and third state, respectively, the low depletion state, medium depletion state, and high depletion state of ink cartridge 2 are examples of the fourth state, fifth state, and sixth state, respectively, the range of sensor detection values ​​from the new state to the maximum depletion state of each ink cartridge 1, 2 is an example of an expected lifespan, the corresponding sensor detection values ​​are examples of the first depletion state quantity and the second depletion state quantity, the medium-large threshold of ink cartridge 1 is an example of the first threshold, and the medium-large threshold of ink cartridge 2 is an example of the second threshold.

[0040] <Control procedure> An example of the control procedure for the consumables ordering process executed by the processor 210 of the multifunction device 200 to realize the above-described method in this embodiment will be described with reference to the flowchart in Fig. 4. First, the multifunction device 200 starts the following procedure after performing an operation to consume consumables, such as printing or regular maintenance of the recording head.

[0041] In S5, it is determined whether or not there are any consumables in a highly consumed state that require replacement among all consumables provided in the multifunction device 200. Specifically, the level of consumption of each consumable is determined by comparing the detection value from the corresponding detection sensor with the above-mentioned consumption level determination table, and it is determined which consumables are in a highly consumed state.

[0042] Next, in S10, it is determined whether or not there is at least one consumable in a highly consumed state. If there is no consumable in a highly consumed state, the determination is NO, and this flow ends. On the other hand, if there is at least one consumable in a highly consumed state, the determination is YES, and the flow proceeds to S15.

[0043] In S15, consumables in a high consumption state are additionally registered in the replacement consumables list 231. In the next S20, it is checked whether there are any consumables in a medium consumption state. The specific method for checking the consumption level is the same as in S5 above. Then, in S25, it is determined whether there are any consumables in a medium consumption state. If there are no consumables in a medium consumption state, a NO determination is made and the process proceeds to S35. On the other hand, if there is any consumable in a medium consumption state, a YES determination is made and the process proceeds to S30. In S30, consumables in a medium consumption state are additionally registered in the replacement consumables list 231, and the process proceeds to S35.

[0044] In S35, it is checked whether any of the consumables currently listed in the replacement consumables list 231 are also listed in the ordered consumables list 232. Then, in S40, it is determined whether any consumables with duplicate listings exist. If there are no consumables with duplicate listings, the result is NO, and the process proceeds to S50. On the other hand, if there is at least one consumable with duplicate listings, the result is YES, and the process proceeds to S45. In S45, the duplicate consumables are deleted from the replacement consumables list 231, and the process proceeds to S50.

[0045] In S50, all consumables currently listed in the replacement consumables list 231 are ordered together. Specifically, the names of the consumables listed in the replacement consumables list 231 and a command requesting their ordering are sent to the information management server 100, causing the ordering process to be performed in cooperation with the delivery management server 400. At this point, the multifunction peripheral 200 of this embodiment notifies the user that the consumables have been automatically ordered and the details of the order by displaying a message window W1, such as that shown in FIG. 5, on the display unit 240. The illustrated message window W1 indicates that, upon detecting that the black (BK) ink cartridge has a low ink level, i.e., a high level of ink consumption, a yellow (Y) ink cartridge, which has a medium ink level, i.e., a medium level of ink consumption, has also been ordered. If, for example, the yellow ink cartridge had already been ordered and was listed in the ordered consumables list 232 at this point, only the black ink cartridge would be ordered and notified. Conversely, or if both ink cartridges have already been ordered, no ordering or notification would be performed at this time. Then, when the ordering process for the consumables listed in the replacement consumables list 231 is completed, the name of the ordered consumables is added to the ordered consumables list 232, and all entries in the replacement consumables list 231 are deleted (not shown). Then, this flow ends.

[0046] In the above, the procedure of S5 is an example of a first judgment process and a second judgment process, the procedures of S15 to S50 are an example of an order selection process, the procedure in the case of a NO judgment at S25 is an example of a first process, and the procedure of S30 in the case of a YES judgment at S25 is an example of a second process.

[0047] <Effects of the embodiment> As described above, in this embodiment, when a consumable item is consumed and an order becomes necessary, multiple consumable items that are nearly consumed to a certain extent are ordered at the same time. To this end, the processor 210 of the multifunction device 200 executes the procedure of S5.

[0048] In step S5, in order to distinguish between three states for the degree of consumption of ink cartridge 1 in the above example, it is determined whether the degree of consumption of ink cartridge 1 falls into a low, medium, or high state. Similarly, in step S5, in order to distinguish between three states for the degree of consumption of ink cartridge 2, which is different from ink cartridge 1 in the above example, it is determined whether the degree of consumption of ink cartridge 2 falls into a low, medium, or high state.

[0049] As ink cartridge 1 and ink cartridge 2 are consumed, their states change in the order of low consumption state → medium consumption state → high consumption state. If ink cartridge 1 consumes faster than ink cartridge 2 and ink cartridge 1 reaches the high consumption state before ink cartridge 2 does, processor 210 will execute steps S15 to S50.

[0050] In the steps S15 to S50, ordering or non-ordering is selectively performed for ink cartridge 1 and ink cartridge 2. If ink cartridge 2 is still in a low-consumed state when ink cartridge 1 reaches a high-consumed state requiring replacement, a NO determination is made in S25, and ordering is performed for ink cartridge 1 only, and non-ordering is performed for ink cartridge 2. If ink cartridge 2 has reached a medium-consumed state when ink cartridge 1 reaches a high-consumed state, a YES determination is made in S25, and ordering is performed for ink cartridge 1 in the steps of S30, and ordering is also performed for ink cartridge 2.

[0051] According to this embodiment, even if the degrees of consumption of ink cartridge 1 and ink cartridge 2 do not match, if ink cartridge 2 has also been consumed to a certain extent by the time ink cartridge 1 reaches a state of significant consumption and ordering processing is performed, ordering processing will also be performed for ink cartridge 2. Because ink cartridge 1 and ink cartridge 2 can be ordered and delivered at the same time, the burden on the user can be reduced compared to when ink cartridge 2 is delivered at a different time after ink cartridge 1 is delivered.

[0052] The above effects are not limited to the same type of consumables, such as the two ink cartridges 1 and 2 in the above example, but can be obtained with different types of consumables as well. The number of consumables is also not limited to two, but can be obtained with three or more consumables.

[0053] Furthermore, in this embodiment, as an exception to the above-described method, even if ink cartridge 2 is in a medium consumption state when ink cartridge 1 is in a high consumption state, if an order has already been placed for that ink cartridge 2, a NO determination is made in S25, and a non-order process is performed for ink cartridge 2, and no order is placed. This embodiment makes it possible to prevent ink cartridge 2 from being repeatedly ordered in duplicate.

[0054] In particular, in this embodiment, there may be cases where ink cartridge 1 has already been ordered when ink cartridge 1 reaches a high level of consumption. In this case, ink cartridge 1 is not ordered. Furthermore, because ink cartridge 1 and ink cartridge 2 cannot be ordered at the same time, an order is not made even if ink cartridge 2 reaches a medium level of consumption. This embodiment makes it possible to prevent only ink cartridge 2 that has not yet reached a high level of consumption from being ordered.

[0055] Furthermore, in this embodiment in particular, a medium-high threshold is set corresponding to the boundary between the medium level of consumption and the high level of consumption for the sensor detection value (remaining ink amount) indicating the level of consumption of ink cartridge 1, and a medium-high threshold is set corresponding to the boundary between the medium level of consumption and the high level of consumption for the sensor detection value (remaining ink amount) indicating the level of consumption of ink cartridge 2. According to this embodiment, it is possible to accurately determine that ink cartridge 1 has transitioned from the medium level of consumption state to the high level of consumption state when the sensor detection value of ink cartridge 1 has reached the corresponding medium-high threshold, and it is possible to accurately determine that ink cartridge 2 has transitioned from the medium level of consumption state to the high level of consumption state when the sensor detection value of ink cartridge 2 has reached the corresponding medium-high threshold.

[0056] Furthermore, in this embodiment, the state of consumption is determined by the sensor detection value indicating the degree of consumption of ink cartridge 1 and the sensor detection value indicating the degree of consumption of ink cartridge 2, but this method is not limited to the above. For example, the state of consumption of ink may be estimated by counting consumption from usage data such as the number of pages printed or the number of times the print head has recorded. For example, in the case of a cutter, the state of consumption may be estimated using an indicator such as the number of cuts. These methods make it possible to determine the state of consumption even when there is no sensor to detect the state of consumption.

[0057] 4 may be performed at a timing other than when a consumable item is consumed, such as when the power is turned on or when the device is connected to the network NT, as long as the timing is appropriate to prompt the user to place an order.

[0058] 4 may be executed periodically, for example, every hour, every day, etc. In this case, the notification in S50 may be displayed when a user operation is performed.

[0059] In particular, in this embodiment, the consumables include any one of an ink cartridge, a waste tank for storing used ink, a recording head, a cutter for cutting the recording medium, and the recording medium. According to this embodiment, when the multifunction device 200 is a so-called inkjet printer, the corresponding multiple consumables can be delivered at the same time, thereby reducing the burden on the user. Note that when the multifunction device 200 is, for example, a laser printer, the consumables include any one of a toner cartridge, a waste toner box for storing used toner, a developing cartridge, a process cartridge, a drum unit, a belt unit, and the recording medium. In this way, when the multifunction device 200 is a so-called laser printer, the corresponding multiple consumables can be delivered at the same time, thereby reducing the burden on the user.

[0060] In the above embodiment, the automatic ordering process according to the consumption state of the consumables in the multifunction device 200 is executed by the processor 210 of the multifunction device 200, but this is not limited to this. Alternatively, the information management server 100 may store, for example, in the nonvolatile storage device 130, a replacement consumables list 231 and an ordered consumables list 232 that individually correspond to each multifunction device 200, and the processor 110 may receive information on the consumption state of each consumable from each multifunction device 200 one by one to execute the automatic ordering process. In this case, the information management server 100 is an example of an external device, the processor 110 is an example of a control unit, the information regarding the consumption state of each consumable is an example of first information and second information, the procedures for acquiring this first information and second information are an example of a first acquisition step and a second acquisition step, the procedure for selectively performing ordering processing or non-ordering processing for which consumable is an example of an order selection step, the procedure for ordering only consumables in a high consumption state is an example of a first step, the procedure for ordering both consumables in a high consumption state and consumables in a medium consumption state is an example of a second step, and information regarding whether the consumption state of the consumable falls into a low consumption state or a medium consumption state is an example of third information. Also, a mobile terminal 300 or an operation terminal configured by a general-purpose personal computer (not shown) may perform the automatic ordering process instead of the multifunction device 200.

[0061] <Modification> The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the spirit and technical concept of the present invention. Such modifications will be described below in order.

[0062] (1) When displaying a confirmation before ordering In the above embodiment, after all consumables listed in the replacement consumables list 231 have been actually ordered, the order details and the execution of the order are displayed in the message window W1 (see FIG. 5 ) to notify the user. However, this is not limited to this. For example, before actually executing the ordering process, a message window W2 shown in FIG. 6 may be displayed to indicate the detection of a high level of consumption for a specific consumable (the “ink cartridge (BK)” in the illustrated example) and the necessity of ordering the consumable, and the user may ultimately select whether or not to place the order. At this time, if another consumable (the “ink cartridge (Y)” in the illustrated example) is listed in the replacement consumables list 231, the message window W2 also displays the same. Furthermore, as in the above embodiment, consumables that have already been ordered are deleted from the replacement consumables list 231 and are not displayed in the message window W2. Note that the names of the consumables displayed in the message window W2 are examples of identification information, and the “Order” button B1 and the “Do not order” button B2 are examples of a confirmation operation unit.

[0063] In this case, as shown in the flowchart in Figure 7, after confirming the elimination of duplicate entries between the replacement consumables list 231 and the ordered consumables list 232, that is, after S40 and S45, a pre-order confirmation display is performed in the procedure of S46. Specifically, the names and consumption states of the consumables listed in the replacement consumables list 231 are displayed in a message window W2 as shown in Figure 6 above, and the user is asked to press either the "Order" button B1 or the "Do not order" button B2. If the "Do not order" button B2 is pressed, the next S48 results in a NO judgment, and the flow ends. On the other hand, if the "Order" button B1 is pressed, the next S48 results in a YES judgment, and the flow proceeds to S50, where the ordering process is executed.

[0064] In the above, the display unit 240 is an example of a display, the message window W2 is an example of an order screen, the steps of S15 to S50 are an example of a first display selection process, the step of S46 in the case where a NO judgment is made in S25 is an example of a third process, and the steps of S30 and S46 in the case where a YES judgment is made in S25 is an example of a fourth process.

[0065] As explained above, in this modified example, even if the levels of consumption of ink cartridge 1 and ink cartridge 2 in the above example do not match, if ink cartridge 2 has also been consumed to a certain extent by the time ink cartridge 1 is significantly consumed, a message window W2 will also be displayed on the display unit 240 for ink cartridge 2. Because both ink cartridge 1 and ink cartridge 2 are displayed in message window W2, ink cartridge 1 and ink cartridge 2 can be ordered and delivered at the same time. This reduces the burden on the user compared to when ink cartridge 2 is delivered at a later time after ink cartridge 1 is delivered. Note that the user may simply be notified of the automatic ordering process in advance, without the need to press the "Order" button B1 or the "Do not order" button B2, or the user may be able to perform the ordering process by performing a separate appropriate operation.

[0066] Furthermore, in this modified example, as an exception to the method described above, even if ink cartridge 2 is in a medium level of consumption when ink cartridge 1 is in a high level of consumption, if an order has already been placed for that ink cartridge 2, no message will be displayed in message window W2. According to this modified example, if the determination is NO in S25, ink cartridges 2 that have already been ordered will not be displayed in the procedure of S46, making it possible to prevent duplicate orders for such ink cartridges 2.

[0067] Furthermore, in this modified example, there are cases where ink cartridge 1 has already been ordered when ink cartridge 1 reaches a high consumption state. In this case, ink cartridge 1 is not displayed in message window W2. Furthermore, because ink cartridge 1 and ink cartridge 2 cannot be ordered at the same time, ink cartridge 2 is not displayed in message window W2. This modified example makes it possible to prevent only ink cartridge 2, which has not yet reached a high consumption state, from being displayed. In this case, since there is nothing to order, message window W2 itself is not displayed.

[0068] In particular, in this modification, an "Order" button B1 and a "Do not order" button B2 are displayed in the message window W2 under the control of the processor 210. According to this modification, the operator can see the names of the consumables displayed in the message window W2 and decide whether or not to order them all at once.

[0069] In this modification, an "Order" button B1 and a "Do Not Order" button B2 may be provided for each consumable item in the message window W2, allowing the user to decide whether or not to order each consumable item individually. For example, a user may obtain consumable items by other means (such as purchasing them at a store) without using the ordering system described above. In this case, the user may already have consumable items that the printer does not recognize. Therefore, by providing a means for the user to individually order items, the user can selectively decide whether to order them all at once or individually, improving convenience.

[0070] (2) When displaying all consumables in the pre-order confirmation display In the first modified example, only consumables in either a high or medium consumption state are displayed in the message window W2 that displays the pre-order confirmation, but this is not limited to this. For example, when one consumable enters a high consumption state, a message window W3 shown in Fig. 8 may be displayed that lists the names of all consumables provided in the multifunction peripheral 200, their consumption states, and their order statuses, allowing the user to order a consumable of their choice from among them.

[0071] The message window W3 shows the display state when the "Ink Cartridge (BK)" is in a "Low Remaining Amount" state, which indicates a high level of depletion. The message window W3 displays a check box CB corresponding to each consumable item, allowing the user to decide whether or not to order the item by checking or unchecking the check box CB. These check boxes CB are initially displayed in a checked, selected state when the corresponding consumable item is in a high or medium level of depletion, and initially displayed in an unchecked, unselected state when the corresponding consumable item is in a low level of depletion.

[0072] The user can change any of the check boxes CB for consumables from their initial display state as desired, and when the "Order" button B1 is finally pressed, all of the consumables corresponding to the checked check boxes CB at that time will be ordered. When the "Do not order" button B2 is finally pressed, the process ends without placing any orders, regardless of the filled-in state of any of the check boxes CB.

[0073] In this modified example, the processor 210 of the multifunction device 200 executes the consumables ordering process shown in the flowchart of Fig. 9. First, in S5A, the current consumption state of each of all consumables provided in the multifunction device 200 is confirmed.

[0074] Next, in S10, it is determined whether or not there is at least one consumable item in a highly consumed state. If there is no consumable item in a highly consumed state, the determination is NO, and this flow ends. On the other hand, if there is at least one consumable item in a highly consumed state, the determination is YES, and the flow proceeds to S55.

[0075] In S55, the order status of the consumables that have been ordered is confirmed by referring to the contents of the currently ordered consumables list 232. Next, in S60, a message window W3 that lists the names, consumption levels, order statuses, and check boxes CB for selecting the display modes that initially correspond to the consumption levels for all consumables is displayed on the display unit 240, and operations from the user are accepted.

[0076] If the "Do not order" button B2 is pressed, the next S65 will result in a NO judgment, and the flow will end. On the other hand, if the "Order" button B1 is pressed, the next S65 will result in a YES judgment, and the flow will move to S50, where the selected consumables are ordered together and their names are registered in the list of ordered consumables. Then, the flow will end.

[0077] Note that the procedure of S5A is an example of a third judgment process, the check box CB is an example of a selection operation unit, the procedures of S55 to S70 are an example of a second display selection process, the procedure of S60 is an example of a fifth process and a sixth process, the display contents of "Ink Cartridge (BK)" and "Remaining Amount (Low)" are an example of a first object, the display contents of "Ink Cartridge (Y)" and "Remaining Amount (Medium)" are an example of a second object, and the display of the contents indicating whether or not an order has already been placed is an example of a third object.

[0078] As explained above, in this modified example, even if the degrees of consumption of ink cartridge 1 and ink cartridge 2 in the above example do not match, when ink cartridge 1 is significantly consumed, a display process is performed to indicate that ink cartridge 1 is in a highly consumed state, and a display process is also performed for ink cartridge 2 to indicate that ink cartridge 2 is in a medium consumed state. Therefore, ink cartridge 1 and ink cartridge 2 can be ordered and delivered at the same time, which reduces the burden on the user compared to when ink cartridge 2 is delivered at a different time after ink cartridge 1 is delivered.

[0079] In particular, in this modification, a check box CB corresponding to each consumable item is displayed in the message window W3 under the control of the processor 210. According to this modification, the operator can select whether or not to include the consumable item, whose name is displayed in the message window W3, in a bulk order.

[0080] In particular, in this modified example, when one consumable item is in a high consumption state and the message window W3 is displayed, if the other consumable items are in a low consumption state, the consumption has not progressed very far and there is little need to order them at that point. In response to this, in this modified example, for consumable items in a low consumption state, the check box CB is displayed in the message window W3 as a default state in which no selection has been made to order (no check mark).

[0081] In addition, when a consumable other than a highly consumed consumable is in a medium consumed state, unlike the above, the consumption has progressed to a certain extent, and there is a high possibility that an order will be placed at that point. In this modified example, to accommodate this, the check box CB is displayed on the order screen with the state in which the selection to be determined has been made (checked state) as the default.

[0082] According to this modified example, a suitable default screen format is realized depending on the situation indicated by the degree of wear of ink cartridge 1 and ink cartridge 2, thereby improving convenience for the operator.

[0083] In particular, in this modification, the order status of all consumables is displayed in the message window W3 under the control of the processor 210. According to this modification, the operator can know whether or not all consumables whose names are displayed in the message window W3 have already been ordered. Furthermore, even for consumables that have already been ordered, the operator can select to order additional consumables.

[0084] Depending on the combination of consumable types, there are combinations that can be delivered simultaneously from the delivery center and combinations that cannot be delivered simultaneously. In response to this, in the display of the message window W3, if ink cartridge 2 in the above example can be delivered simultaneously with ink cartridge 1, the name and state of wear of ink cartridge 2 may be displayed, but if ink cartridge 2 cannot be delivered simultaneously with ink cartridge 1, the name and state of wear of ink cartridge 2 may not be displayed (not shown).

[0085] According to this, as an exception to the above method, even if the name and state of wear of ink cartridge 1 are displayed when it has become significantly worn out, the name and state of wear of ink cartridge 2 will not be displayed if it cannot be delivered at the same time as ink cartridge 1. This makes it possible to prevent ink cartridge 1 and ink cartridge 2 from being mistakenly ordered at the same time in cases where, for example, it is physically impossible to deliver ink cartridge 1 and ink cartridge 2 at the same time due to circumstances on the part of the delivery company.

[0086] As an alternative to the above modification, consumables that can be delivered simultaneously may be displayed together in an upper and lower row, with a display indicating that the deliveries will be separate. This makes it easy for the operator to select and order only the consumables that can be delivered simultaneously (not shown).

[0087] Furthermore, the present invention is not limited to the procedures shown in the flows of FIGS. 4 and 7, and steps may be added or deleted, or the order may be changed.

[0088] In addition to the above, the methods according to the above embodiments and modifications may be used in appropriate combination. [Explanation of symbols]
