Abstract

To allow for quickly and easily performing printing without carrying a printer by inputting a print instruction and a print schedule from a mobile terminal.SOLUTION: A smartwatch displays a calendar on a display part (S11). A user taps a desired date in the calendar to designate a print date (S12). When the print date is designated, the smartwatch displays a print timing selection screen on the display part (S13). As the print timing, the user can select either "printing on arrival," in which printing starts upon the user's arrival at a designated image forming apparatus, or "printing date and time designation," in which a printing time is designated in addition to the print date. If the user selects "printing on arrival" (S14: printing on arrival), the smartwatch proceeds to processing for printing on arrival (S15). If the user selects "printing date and time designation" (S14: printing date and time designation), a control unit of the smartwatch proceeds to processing for printing date and time designation (S16).SELECTED DRAWING: Figure 3

[0014] 2 is an external view of a smart watch 9, which is an example of the mobile terminal 1. A touch panel, which is the input receiving unit 12, and a display unit 121 are disposed so as to overlap each other.

[0015] Returning to FIG. 1, the server 2 provides data and services in response to requests from the mobile terminal 1, the image forming device 3, etc. The server 2 comprises a control unit 21, a storage unit 22, a communication unit 23, etc. The control unit 21 comprises a processor, RAM, ROM, etc. The processor is a CPU, MPU, ASIC, etc.

[0016] The control unit 21 functions as a control unit 211 by the processor executing a control program stored in a ROM or the like. Each of the above-mentioned parts of the control unit 21 may be configured by a hardware circuit, without relying on the operation based on the control program. The control unit 211 is responsible for the overall operational control of the server 2.

[0017] The storage unit 22 is a large-capacity storage device consisting of an SSD or HDD (Hard Disk Drive) that stores various programs, etc., and stores various data, programs, etc. The communication unit 23 is composed of a communication module, etc., and transmits and receives various data to and from external devices via the network N.

[0018] The image forming device 3 is a printer or a multifunction device having at least a printing function, etc. The image forming device 3 is configured with a control unit 31, an input receiving unit 32, an image reading unit 33, an image forming unit 34, a storage unit 35, a communication unit 36, etc.

[0019] The control unit 31 functions as a control unit 311 by the processor executing a control program stored in a ROM or the like. Each of the above-mentioned parts of the control unit 31 may be configured by a hardware circuit, without relying on the operation based on the control program. The control unit 311 is responsible for the overall operational control of the image forming apparatus 3.

[0020] The input reception unit 32 includes hardware keys such as a decision key for confirming various operations and settings, a start key, and a display unit 321. The display unit 321 displays operation screens, messages, and the like, and may be integrated with a touch panel. The input reception unit 32 displays the following in response to the user's operation of each key or the touch panel: Accepts various instructions.

[0021] The image reading unit 33 includes a scanner and the like, and reads an image of a document to obtain the document image. The image forming unit 34 is an electrophotographic image forming mechanism including a photosensitive drum, a static electricity-resistant device, an exposure device, a developing device, and a transfer device.

The memory unit 35 is a large-capacity storage device consisting of an SSD or HDD that stores image data, various programs, data tables, etc. The communication unit 36 ​​is composed of a communication module and the like, and transmits and receives various data to and from external devices via the network N.

[0022] Next, a printing process when a print instruction is given from the smartwatch 9 to the image forming device 3 will be described. FIG. 3 is a flowchart for explaining the flow of the printing process. For example, the user wears the smartwatch 9 on his / her wrist. The user operates the touch panel of the smartwatch 9 to select a document or image to be printed, and the control unit 111 causes the display unit 121 to display the selected document or image and an ellipsis 91. FIG. 6 is a diagram showing an example of the display unit 121 of the smartwatch 9 at this time. Here, a file such as a document to be printed is stored in the memory unit 13 of the smartwatch 9, or is stored in a cloud storage. The control unit 111 reads out the specified file from the memory unit 22 according to a file designation instruction from the user inputted to the input receiving unit 12, or accesses the cloud storage from the communication unit 14 and transmits the specified file from the storage to be received by the communication unit 14. The control unit 111 causes the display unit 121 to display the read file or the received file as a document or image to be printed.

[0023] When the user touches the three dots 91 during this display, a menu display instruction is received by the touch panel, and the control unit 111 displays the print setting menu 92 on the display unit 121 in accordance with the menu display instruction. Fig. 7 is a diagram showing an example of the display on the display unit 121 of the smart watch 9 at this time. When the user touches the "Print reservation" button 921 on the print setting menu 92 at this time, a calendar display instruction is received by the touch panel.

[0024] In accordance with the calendar display instruction, the control unit 111 causes the display unit 121 to display a calendar for selecting a printing date (S11). Fig. 8 is a diagram showing an example of the display on the display unit 121 at this time.

[0025] When the user taps a desired date on the calendar, the touch panel accepts the tapped date as the designated print date (S12). FIG. 8 shows a display state when May 12, 2023 is accepted as the print date. When the print date is accepted, the control unit 111 causes the display unit 121 to display a print timing selection screen (S13). FIG. 9 is a diagram showing an example of the print timing setting screen G1 displayed on the display unit 121 at this time.

[0026] The printing timing includes "arrival printing", which starts printing when the document arrives at the image forming device 3 specified by the user, and "printing date and time specification", which specifies the printing time in addition to the printing date. The printing timing setting screen G1 displays a button 93 for accepting an instruction to specify "arrival printing", and a button 94 for accepting an instruction to specify "printing date and time specification". When the user touches the "arrival printing" button 93 (S14; arrival printing), the arrival printing specification instruction is accepted on the touch panel, and the control unit 111 shifts the process to arrival printing processing (S15). When the user touches the "printing date and time specification" button 94 (S14; printing date and time specification), the print date and time specification instruction is accepted on the touch panel, and the control unit 111 shifts the process to print date and time specification processing (S16).

[0027] 4 is a flowchart showing the flow of the arrival printing process. In the arrival printing process, the control unit 111 of the smart watch 9 causes the communication unit 14 to transmit a request for a list of printable image forming devices 3 and the terminal identification information of the own device to the server 2 (S31). The printable image forming devices 3 are image forming devices that are in a state where they can print the print file transmitted from the server 2, and information indicating the image forming devices in a state where they can print is stored in a non-volatile memory or the like built into the control unit 11 of the server 2.

[0028] The terminal identification information is information for identifying the type of the mobile terminal 1. The type is, for example, type information indicating a wearable terminal, a smartphone, a smart watch, or a tablet terminal. In the case of a smart watch 9, the terminal identification information indicating that the mobile terminal itself is a smart watch is transmitted to the server 2. The terminal identification information may be, for example, a product number, and in this case, the server 2 obtains information indicating the type of the mobile terminal 1 by searching the product number transmitted from the mobile terminal 1 using the Internet N or the like.

[0029] Then, the control unit 211 of the server 2 creates a list of image forming devices 3 that are ready for printing, and transmits the list to the smartwatch 9 from the communication unit 23 (S42). When the communication unit 14 receives the list transmitted from the server 2, the control unit 111 of the smartwatch 9 causes the display unit 121 to display the list (S32). Fig. 10 is a diagram showing an example of the display on the display unit 121 at this time.

[0030] In the server 2, the control unit 211 creates a list in which the amount of model information and status information of the image forming device 3 is changed according to the type of the mobile terminal 1 indicated by the terminal identification information. When the terminal identification information received by the communication unit 23 from the mobile terminal 1 indicates a predetermined small terminal type (e.g., a smart watch), the control unit 211 creates a list of the image forming devices 3 that are in a printable state, simplified for display on a terminal of the small terminal type, and causes the communication unit 23 to transmit the simplified list to the mobile terminal 1 of the small terminal type.

[0031] For example, if the terminal identification information indicates a smartwatch 9, the display unit 121 of the smartwatch 9 is small and therefore cannot display much information about the image forming devices 3. Therefore, the control unit 211 of the server 2 creates a list including only the minimum information, such as the device names (names) of the image forming devices 3 capable of printing and distance information from the smartwatch 9 to each image forming device 3, and transmits the list to the smartwatch 9.

[0032] On the other hand, if the mobile terminal 1 is a smartphone or a tablet terminal, etc., information about the image forming device 3 can be sufficiently displayed on the display unit 121. Therefore, the control unit 211 of the server 2 creates a list including the device names (names) of the image forming devices capable of printing and distance information from the mobile terminal 1 to each image forming device 3, as well as status information of each image forming device (online availability, toner status, paper storage status, number of print jobs, etc.), and transmits the list to the mobile terminal 1 from the communication unit 23.

[0033] When the mobile terminal 1 indicated by the terminal identification information is a smartphone or a tablet terminal, that is, when it is not a predetermined small terminal such as a smartwatch 9, the control unit 211 of the server 2 requests a status from the image forming device 3 capable of printing via the communication unit 23 (S41). When the image forming device 3 receives the request via the communication unit 36, the control unit 311 transmits its own status information from the communication unit 36 ​​to the server 2 (S51). The server 2 creates the above-mentioned list using the status information received from the image forming device 3 via the communication unit 23, and transmits the created list from the communication unit 23 to the mobile terminal 1 (S42). The control unit 111 of the mobile terminal 1 causes the display unit 121 to display the list received via the communication unit 14 (S32).

[0034] 11 is a diagram showing an example of the list displayed on the display unit 121M when the mobile terminal 1 is a smartphone. In this way, the control unit 211 of the server 2 creates a list by varying the amount of information about the image forming device 3 depending on the type of mobile terminal 1, thereby making it possible to display an amount of information suitable for the size of the display unit 121 of the mobile terminal 1.

[0035] In the following, the mobile terminal 1 will be described as a smart watch 9 again. Return to FIG. 4. When the user performs an operation to select the image forming device 3 from the displayed list and an instruction to select the image forming device 3 based on the operation is received by the touch panel, the control unit 111 of the smart watch 9 transmits information indicating that the selected image forming device 3 is the print destination from the communication unit 14 to the server 2 (S33). At this time, together with the selection of the image forming device 3, a predetermined default print setting is received by the touch panel as the print setting by the image forming device 3. The smart watch 9 is a small terminal that is predetermined to have a small display unit. In this case, the input receiving unit 12 of the smart watch 9 receives the print setting of the image forming device 3 with simple contents (default setting). At this time, the control unit 111 causes the display unit 121 to display a message indicating that the arrival print setting has been completed. FIG. 12 is a diagram showing an example of the display of the display unit 121 of the smart watch 9 at this time.

[0036] In the server 2, when the control unit 211 receives information indicating the image forming device 3 to be the printing destination from the smartwatch 9 via the communication unit 23, the control unit 211 transmits the location information of the image forming device 3 from the communication unit 23 to the smartwatch 9 (S43). The location information of the image forming device 3 may be stored in advance in the storage unit 22 of the server 2, or the control unit 211 of the server 2 may request the location information of the image forming device 3 from the communication unit 23, receive the location information of the image forming device 3 itself from the image forming device 3, and transfer the corresponding location information stored in the storage unit 22 or the received location information from the communication unit 23 to the smartwatch 9.

[0037] The control unit 111 of the smartwatch 9 compares the location information of the image forming device 3 as the printing destination with the location information acquired from the GPS 15 to determine whether the smartwatch 9 has arrived at the location of the image forming device 3 (S34). If the control unit 111 determines that the smartwatch 9 has arrived at the image forming device 3 (S34; YES), it transmits the print file selected as the print target (the document or image to be printed described above) from the communication unit 14 to the server 2 (S35).

[0038] The control unit 211 of the server 2 transfers the print file received from the smartwatch 9 via the communication unit 23 from the communication unit 23 to the image forming device 3 as the print destination (S44), and the control unit 311 of the image forming device 3 causes the image forming unit 34 to print on paper an image indicated by the print file received via the communication unit 36 ​​(S52). After completing the printing, the control unit 311 transmits a notification signal of the printing completion from the communication unit 36 ​​to the server 2 (S53). The control unit 211 of the server 2 causes the communication unit 23 to further transfer the notification signal of the printing completion received from the image forming device 3 via the communication unit 23 to the smartwatch 9 (S45).

[0039] When the smartwatch 9 receives a printing completion notification signal from the server 2 via the communication unit 14, the control unit 111 causes the display unit 121 to display a printing completion message (S36). Fig. 14 is a diagram showing an example of the display on the display unit 121 of the smartwatch 9 at this time. In this way, by being able to configure settings for arrival printing processing from the smartwatch 9, printing can be performed quickly and easily without the need to carry a printer.

[0040] Next, the flow of the print date and time designation process in this embodiment will be described. Fig. 5 is a flowchart showing the flow of the print date and time designation process. Note that the description of the print date and time designation process that is the same as the arrival printing process will be simplified. First, the control unit 111 of the smart watch 9 causes the communication unit 23 to transmit the terminal identification information of the smart watch 9 to the server 2 together with a request for a list of image forming devices 3 that can print (S61).

[0041] When the communication unit 23 of the server 2 receives the list request and its own terminal identification information from the smartwatch 9, the control unit 211 sends a list of printable image forming devices 3 from the communication unit 23 to the smartwatch 9 (S72). The control unit 111 of the smartwatch 9 causes the display unit 121 to display the list received via the communication unit 14 (S62). Fig. 10 is a diagram showing an example of the display on the display unit 121 at this time.

[0042] On the other hand, when the communication unit 23 of the server 2 receives the list request and the terminal identification information of the own machine from the mobile terminal 1, if the mobile terminal 1 is a smartphone or a tablet terminal, the control unit 211 requests the status of each printable image forming device 3 via the communication unit 23 (S71). The image forming device 3 that receives the request via the communication unit 36 ​​causes the control unit 311 to transmit the status information of the own machine to the server 2 from the communication unit 36 ​​(S81). The control unit 211 of the server 2 creates the list using the status information received from the image forming device 3 via the communication unit 23, and transmits the created list from the communication unit 23 to the mobile terminal 1 (S72). The control unit 111 of the mobile terminal 1 causes the display unit 121 to display the list received via the communication unit 14 as shown in FIG. 11 (S62).

[0043] Here, the user performs an operation to select the image forming device 3 from the displayed list, and an instruction to select the image forming device 3 based on the operation is received by the touch panel. Furthermore, the user operates a change button 99 for instructing to change the details of the print settings for the image forming device 3 from the displayed list, and an instruction to change the displayed details (here, the paper size is shown as an example) is received by the touch panel. The control unit 111 of the mobile terminal 1 transmits the print settings including the information that the selected image forming device 3 is the print destination and the changed details from the communication unit 14 to the server 2 (S63). The smartphone, tablet terminal, etc. are large terminals that are predetermined to have a large display unit. In this case, the input receiving unit 12 of the smartphone, tablet terminal, etc. receives the print settings of the image forming device 3 in detail (the above-mentioned details).

[0044] In the following, the mobile terminal 1 will again be described as a smart watch 9. Returning to FIG. 5, when the user performs an operation to select an image forming device 3 from the displayed list and an instruction to select an image forming device 3 based on the operation is received by the touch panel, the control unit 111 of the smart watch 9 transmits information specifying the selected image forming device 3 as the printing destination from the communication unit 14 to the server 2 (S63). The control unit 111 causes the display unit 121 to display a print time selection screen G2. FIG. 13 is a diagram showing an example of the print time selection screen G2 displayed on the display unit 121 of the smart watch 9 at this time.

[0045] During this display, a print date designation instruction is accepted on the touch panel in response to a user's operation of the print date setting button 96. Also, a print time designation instruction is accepted on the touch panel in response to a user's operation of the time setting button 97 displayed on the print time selection screen G2. Furthermore, when a print time confirmation instruction is accepted on the touch panel in response to a user's operation of the confirm button 95, the control unit 111 transmits print date and time information consisting of the print date and print time that have been set, and the print file selected as the print target to the server 2 (S64). When the time reaches the print date and time indicated by the print date and time information received by the communication unit 23 (S73; YES), the control unit 211 of the server 2 transfers the print file received by the communication unit 23 to the image forming device 3 selected as the print destination via the communication unit 23 (S74). In the image forming device 3, the control unit 311 causes the image forming unit 34 to print the image indicated by the print file received via the communication unit 36 ​​on paper (S82). When the printing is completed, the control unit 311 transmits a printing completion notification signal from the communication unit 36 ​​to the server 2 (S83). When the control unit 211 of the server 2 receives the printing completion notification signal via the communication unit 23, the control unit 211 causes the communication unit 23 to transfer the printing completion notification signal to the smartwatch 9 (S75).

[0046] When the control unit 111 of the smart watch 9 receives a notification signal of the printing completion from the server 2 via the communication unit 14, it causes the display unit 121 to display a message of the printing completion (S65). Fig. 14 is a diagram showing an example of the display on the display unit 121 of the smart watch 9 at this time.

[0047] As explained above, arrival printing and printing date and time settings can be performed from the smartwatch 9, so users can easily issue print instructions even if they do not have a smartphone or tablet device at hand.

[0048] In addition, the server 2 can change the amount of information displayed in the list of image forming devices 3 capable of printing depending on whether the mobile terminal 1 is a smartwatch or a smartphone or tablet terminal, thereby enabling the display to be suited to the size of the display unit 121 of the mobile terminal 1, and providing the user with an appropriate amount of information. Therefore, according to this embodiment, printing instructions and a printing schedule can be input from the mobile terminal 1, and printing can be performed quickly and easily without the need to carry a printer.

[0049] The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. In addition, in the above embodiment, the configuration and processing shown in the above embodiment using Figures 1 to 14 are merely one embodiment of the present invention, and the present invention is not limited to the configuration and processing.
