Description

[Technical field]

[0001] The present invention relates to an information display device, an information display method, and a program. [Background technology]

[0002] Conventionally, in order to protect the print head from shaking and shock during delivery, printers such as inkjet printers are fitted with packaging material near the print head when shipped. When a printer is purchased, the user performs initial settings after turning the printer on for the first time, and the initial settings include adjusting the position of the print head as part of the printing preparation process. If the printer is turned on without removing the packaging material and the print head position is adjusted, the unnecessary packaging material will interfere with the operation of the print head, causing an error related to the print head. In this way, printers can sometimes cause errors during initial settings.

[0003] Patent Document 1 discloses a technology that switches the error content displayed on the operation panel of an inkjet printer depending on whether an error occurs with the print head, depending on whether the printer is initially set up or not. With this technology, if the printer is initially set up, error information is displayed that prompts the user to remove the packaging material, and if the printer is not initially set up, error information is displayed that prompts the user to notify an external service station.

[0004] [Patent Document 1] JP 2000-335052 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, as devices in which errors may occur during initial setup become more widespread, there is a demand for appropriate control of the screen that is displayed when an error occurs during initial setup.

[0006] In view of the above-mentioned problems, an object of the present invention is to make it possible to appropriately control the screen displayed when an error occurs during initial setup. [Means for solving the problem]

[0007] The information display device of the present invention is an information display device that displays information related to initial settings, and is characterized in having a detection means for detecting the presence or absence of an object that may hinder the initial settings, a detection means for detecting the opening and closing of a cover of the information display device, and a display control means for displaying guide information for performing the initial settings on the display unit when the object is detected by the detection means without the detection means detecting the opening and closing of the cover, and for displaying error information related to the initial settings on the display unit when the object is detected by the detection means after the detection means detects the opening and closing of the cover.

[0010] Hereinafter, an embodiment of the present invention will be described by way of example with reference to the drawings. However, the components described in the present embodiment are merely exemplary embodiments of the present invention, and the scope of the present invention is not limited to these components.

[0011] (First embodiment) 1 is a diagram showing an example of the external configuration of a printing device 100 according to this embodiment. In this embodiment, the printing device 100 will be described as a multifunction printing device (MFP) that has a scanner function and a communication function in addition to a printing function.

[0012] In Fig. 1, operation panel 101 is a display unit equipped with a touch panel, and displays a screen for displaying the status of printing device 100 and a UI screen for performing various settings. Access cover 102 is a cover that is opened when replacing ink or print head. Print paper insertion port 103 is an insertion port for setting paper of various sizes. Paper set here is transported one sheet at a time to the printing unit, where the desired printing is performed and the paper is discharged from print paper discharge port 104. Print head 105 prints by ejecting ink onto the paper carried in from print paper insertion port 103.

[0013] 2 is a block diagram showing an example of the internal configuration of the printing device 100 according to this embodiment. As shown in FIG. 2, the printing device 100 includes a control unit 110, an operation unit 120, a printing unit 130, a scanner unit 140, and a communication unit 150. The control unit 110 includes a CPU 111 and a data storage unit 112, and controls the entire printing device 100. The data storage unit 112 is composed of a ROM, a RAM, etc., and stores image data, control data, etc. in addition to various programs executed by the CPU 111. The control unit 110 also controls the display of various information on the operation panel.

[0014] The operation unit 120 is composed of the above-mentioned operation panel 101, and accepts operations by the user and displays various screens. The printing unit 130 includes the above-mentioned access cover 102 and print head 105, and further includes an access cover opening / closing sensor 131. The access cover opening / closing sensor 131 is a sensor for detecting the opening / closing of the access cover 102. When the access cover opening / closing sensor 131 detects the opening / closing of the access cover 102, the CPU 111 generates history data and stores it in the data storage unit 112. The scanner unit 140 reads an image using a scanning mechanism with an optical sensor. Then, the CPU 111 stores the read image as image data in the data storage unit 112. The communication unit 150 exchanges data with an external device via a wireless LAN or a USB cable.

[0015] FIG. 3 is a flowchart showing an example of a packing material removal confirmation process in this embodiment. Note that this flowchart is realized by the CPU 111 loading a control program stored in the ROM of the data storage unit 112 into the RAM of the data storage unit 112 and executing the control program. This flowchart starts when the user turns on the printing device 100. Note that this flowchart may be executed only when the printing device 100 is turned on for initial setting, and may not be executed when the printing device 100 is turned on after the initial setting is completed. The initial setting is a process executed when the printing device 100 is turned on for the first time after arrival. In this embodiment, the initial setting includes a language setting process, a usage environment setting process, a date and time setting process, a packing material removal confirmation process, a firmware confirmation process, an ink cartridge detection process, a registration adjustment process, and a cleaning process. Also, in the initial setting, each process is executed in the following order: language setting process, usage environment setting process, date and time setting process, packing material removal confirmation process, firmware confirmation process, ink cartridge detection process, registration adjustment process, and cleaning process. Therefore, it is assumed that a language setting process, a usage environment setting process, and a date and time setting process are executed before this flowchart. The language setting process is a process that accepts a user operation for setting a language used by the printing device 100 for display. The usage environment setting process is a process that accepts a user operation for setting a country or region in which the printing device 100 is used. The date and time setting process is a process that accepts a user operation for setting the current date and time. The packing material removal confirmation process is a process that will be described using this flowchart, and is a process that confirms whether the packing material has been removed from the printing device 100. Note that the packing material is a material that packs the printing device 100 for arrival, and specifically, for example, a fixing material that fixes the print head so that the print head does not move during transportation. Therefore, the packing material is, in other words, a fixing material. Specifically, the fixing material is a tape or a plastic material. The firmware confirmation process is a process that confirms whether the firmware of the printing device 100 is the latest version.If it is confirmed that the firmware of the printing device 100 is not the latest version, the firmware confirmation process may include a process of updating the firmware of the printing device 100 to the latest version. The ink cartridge detection process is a process of detecting whether or not an ink cartridge is installed in the printing device 100. If it is detected that an ink cartridge is not installed in the printing device 100, the ink cartridge detection process may include a process of displaying a guide screen that prompts the user to install an ink cartridge in the printing device 100, or an error screen that includes guide information indicating that an ink cartridge is not installed in the printing device 100. The registration adjustment process is a process of adjusting the landing position of ink ejected from the print head. The cleaning process is a process of cleaning the print head. Note that the processes and the order of the processes included in the initial setting are not limited to the above-mentioned form. Therefore, a process different from the above-mentioned may be executed before or after the packaging material removal confirmation process.

[0016] First, in S201, the control unit 110 detects the state of the print head 105 by moving the print head 105, and judges whether an error related to the print head has been detected. If an object such as a packing material is present in the movement path of the print head 105, the object becomes an obstacle and the print head 105 does not move normally, and an error is detected. On the other hand, if there is no object such as a packing material in the movement path of the print head 105, the print head 105 moves normally, and an error is not detected. If the print head 105 can move from the standby position to the printing position where the print head 105 ejects ink and executes printing, the print head 105 is deemed to have moved normally, and if it cannot move, the print head 105 is deemed to have not moved normally. If an error is detected by this judgment, the process proceeds to S202 to prompt the removal of the packing material. On the other hand, if no error is detected and the print head 105 moves normally, the packing material is deemed to have been removed, and this flow ends. After this flow ends, each process included in the initial setting may be executed.

[0017] Next, in S202, the control unit 110 determines whether the access cover 102 has been opened or closed after the power is turned on. In this process, the control unit 110 determines whether the access cover 102 has been opened or closed by referring to the history data of the detection by the access cover opening / closing sensor 131. If it is determined that the access cover 102 has been opened or closed after the power is turned on, it is assumed that the access cover 102 has been opened in order for the user to perform an operation to remove the packaging material, and the process proceeds to S203. Note that the determination in S202 in the case where it is determined that the access cover 102 has been opened or closed after the power is turned on is the second determination in S202 after the power is turned on, and is a determination after the guide screen 501 is displayed based on the first determination result after the power is turned on. In other words, the determination in S202 in this case is a determination performed when an error related to the print head is detected again due to the user's failure to remove the packaging material despite the guide screen 501 being displayed. On the other hand, if it is determined that the access cover 102 has not been opened or closed after power-on, it is assumed that the user has not yet performed the operation to remove the packaging material, and the process proceeds to S204. Note that this determination in S202 when it is determined that the access cover 102 has not been opened or closed after power-on is the first determination in S202 after power-on, and is a determination made in a state where neither the guide screen 501 nor the error screen 502 has been displayed yet after power-on.

[0018] FIG. 6 is a diagram showing an example of a screen displayed on the operation panel 101. In S203, the control unit 110 displays, for example, an error screen 502 shown in FIG. 6(b) on the operation panel 101. The error screen displayed in S203 is a screen for urging the user to open the access cover 102 and remove the packaging material. In other words, the error screen 502 is a first notification screen for notifying the user that the packaging material has not been removed. The error screen is error information that indicates an operation error by the user, and includes a message that can clearly inform the user that the user's operation was incorrect. After the error screen 502 is displayed, when the user removes the packaging material and the access cover opening / closing sensor 131 detects that the access cover 102 is closed, the process returns to S201.

[0019] On the other hand, in S204, the control unit 110 displays a guide screen 501 shown in FIG. 6A on the operation panel 101. The guide screen 501 displayed in S204 is a screen for urging the user to open the access cover 102 and remove the packaging material. Therefore, the guide screen 501 includes a message for urging the user to open the access cover 102 and remove the packaging material, and an image for explaining to the user the procedure and method of removing the packaging material. In other words, the guide screen 501 is a second notification screen for notifying the user that the packaging material has not been removed. For example, the guide screen 501 may display a URL for displaying a WEB manual for explaining to the user the procedure and method of removing the packaging material, or a QR code (registered trademark) for displaying the WEB manual using the URL. The WEB manual can be displayed on the terminal device by inputting the URL into a WEB browser of a terminal device such as a smartphone, or by reading the QR code using the terminal device. After guide screen 501 is displayed, the user opens access cover 102 to remove the packaging material, and when access cover opening / closing sensor 131 detects that access cover 102 has been closed, the process returns to S201.

[0020] In the above description, the message displayed on error screen 502 and the message displayed on guide screen 501 are different. Also, error screen 502 does not include an image for explaining to the user the procedure and method for removing packaging material, and guide screen 501 includes an image for explaining to the user the procedure and method for removing packaging material. However, the difference between error screen 502 and guide screen 501 is not limited to this form, and it is sufficient that at least a part of the area on the screen is different. Specifically, for example, the difference between error screen 502 and guide screen 501 may be that the icons or images displayed on the screen are different.

[0021] After the process of the flowchart in FIG. 3 is completed, the control unit 110 executes one or more setting processes (hereinafter, later-stage processes) that are processes included in the initial setting and are subsequent to the packing material removal confirmation process. Specifically, in this embodiment, the control unit 110 executes a firmware confirmation process, an ink cartridge detection process, a registration adjustment process, and a cleaning process as subsequent-stage processes. Therefore, in this embodiment, if an error occurs regarding the first print head before the subsequent-stage processes are performed, a guide screen 501 is displayed. Then, if an error occurs regarding the second or subsequent print heads before the subsequent-stage processes are performed, an error screen 502 is displayed. Also, in this embodiment, if an error occurs regarding the first print head before all processes included in the initial setting are completed, a guide screen 501 is displayed. Then, if an error occurs regarding the second or subsequent print heads before all processes included in the initial setting are completed, an error screen 502 is displayed. Note that, when all processes included in the initial setting are completed, the control unit 110 displays a home screen, and various functions of the printing device 100 can be executed. Note that an error regarding the print head may occur even after all processes included in the initial setting are completed. Therefore, even after all the processes included in the initial setting are completed, a detection process may be executed to detect whether an error related to the print head has occurred, which is the same process as the packaging material removal confirmation process. Specifically, for example, when printing is instructed in the printing device 100, the detection process may be executed before printing based on the instruction is executed. If an error related to the print head is detected in this detection process, regardless of whether it is the first or second error, the guide screen 501 may not be displayed and the error screen 502 may be displayed. In other words, in this embodiment, before the initial setting is completed, the screen displayed when an error related to the print head is detected for the first time is different from the screen displayed when an error related to the print head is detected for the second or subsequent times.On the other hand, after the initial settings are complete, the screen displayed when an error related to the print head is detected for the first time will not be different from the screen displayed when an error related to the print head is detected for the second or subsequent times.

[0022] As described above, according to the present embodiment, when the user has not completely removed the packaging material, the screen displayed on the operation panel 101 is switched from the guide screen to the error screen. This allows the user to clearly recognize the cause of the failure. Specifically, for example, even though an error occurs in the printing device 100 and the user performs an operation to clear the error, the operation may be incorrect and cause another error to occur. In this case, in a form in which the guide screen is displayed uniformly regardless of the number of errors that have occurred, or in a form in which the error screen is displayed uniformly regardless of the number of errors that have occurred, there is a problem that it is difficult for the user to know whether the operation was incorrect and caused another error, or whether the operation was correctly cleared but the printing device 100 did not recognize this and the screen based on the first error remains displayed. Therefore, in this embodiment, by switching the display between the first error and the second error, it is possible to make the user easily recognize that a second error has occurred when a second error occurs. In addition, when a second error occurs, the display can be switched from the guide screen to the error screen to prompt the user to perform the second error clearing operation more carefully.

[0023] Second embodiment In the first embodiment, a configuration was described in which the content displayed on the operation panel 101 is switched depending on whether the access cover 102 has been opened or closed. In contrast, in the present embodiment, an example is described in which the opening and closing time of the access cover 102 is also taken into consideration when an error is detected in the state of the print head. For example, if the user touches the access cover 102 and opens it for a moment and then closes it immediately after the guide screen 501 is displayed on the operation panel 101, the screen displayed on the operation panel 101 is switched from the guide screen 501 to the error screen 502 in the processing procedure of FIG. 3. If the screen transitions to the error screen, the user will not be able to accurately remove the packaging material while looking at the guide screen 501, and such a screen transition is not desirable for the user. Therefore, in the present embodiment, an example is described in which the screen is not updated when the opening and closing time of the access cover 102 is extremely short. Note that the external appearance and internal configuration example of the printing device according to this embodiment are the same as those of FIG. 1 and FIG. 2, respectively, and therefore the description will be omitted. Only the differences from the first embodiment will be described below.

[0024] In this embodiment, control unit 110 measures the time from when access cover opening / closing sensor 131 detects that access cover 102 is open to when it detects that access cover 102 is closed. Then, when access cover opening / closing sensor 131 detects that access cover 102 is open or closed, information on the measured open time is included in the history data.

[0025] 4 is a flowchart showing an example of a process procedure for displaying information when an error is detected in the print head in this embodiment. S301 and S302 are the same as S201 and S202 in Fig. 3. If the result of the determination in S302 is that the access cover 102 has been opened or closed, the process proceeds to S303, which will be described below.

[0026] In S303, control unit 110 determines whether the open time of access cover 102 most recently opened and closed was equal to or longer than a predetermined value. If control unit 110 refers to the history data and finds that the open time of access cover 102 most recently opened and closed was equal to or longer than a predetermined value, control proceeds to S304. The process of S304 is the same as S203 in FIG. 3.

[0027] On the other hand, if the result of the determination in S304 is that the open time of the access cover 102 that was opened most recently is less than the predetermined value, the process proceeds to S305. In S305, the control unit 110 causes the display content of the operation panel 101 to continue. For example, even if a guide screen is displayed on the operation panel 101 and the user touches the access cover 102 before intentionally opening it, and the access cover 102 is opened for a moment and then closed, the guide screen is caused to continue to be displayed. Also, even if an error screen is displayed after the user opens the access cover 102 and removes the packaging material, and then the user touches the access cover 102, opens it for a moment, and then closes it, the error screen is caused to continue to be displayed. When the access cover opening / closing sensor 131 detects that the access cover 102 is closed, the process returns to S201. The process in S306 is the same as S204 in FIG. 2.

[0028] As described above, according to this embodiment, if the user unintentionally opens the access cover 102 for just an instant, the printing device 100 is configured not to update the display screen of the operation panel 101. This allows the user to continue removing the packaging material while viewing the guide screen.

[0029] (Third embodiment) In the first embodiment, a configuration in which the content displayed on the operation panel 101 is switched depending on whether the access cover 102 is opened or closed is described. In contrast, in the present embodiment, a configuration in which multiple types of error screens are prepared to be displayed on the operation panel 101 and an appropriate error screen is switched will be described. In the processing procedure of FIG. 3, if the user does not sufficiently remove the packaging material after the error screen 502 is displayed on the operation panel 101, the same error screen 502 is displayed on the operation panel 101 again. Since there is no change in the information that the user reads from the content displayed on the operation panel 101, the user may not be able to understand the cause of the failure in removing the packaging material. In order to solve such a problem, in the present embodiment, a configuration in which the screen displayed on the operation panel 101 is switched depending on the number of errors is described. Note that the external appearance and internal configuration example of the printing device according to this embodiment are the same as those of FIG. 1 and FIG. 2, respectively, and therefore the description will be omitted. Only the differences from the first embodiment will be described below.

[0030] Fig. 5 is a flowchart showing an example of a process procedure for displaying information when an error is detected in the print head in this embodiment. S401 and S402 are the same as S201 and S202 in Fig. 3. If the result of the determination in S402 is that the access cover 102 has been opened or closed, the process proceeds to S403, which will be described below.

[0031] In S403, control unit 110 determines whether the error detected after access cover 102 is opened or closed is the first one. In this embodiment, control unit 110 counts the number of times an error is detected and stores the number in the RAM of data storage unit 112. If the result of this determination is that the error is the first one, the process proceeds to S404. S404 is the same as S204 in FIG.

[0032] On the other hand, if the result of the determination in S403 is that it is the second or more times, the process proceeds to S405. Then, in S405, in order to present the support number to the user, the control unit 110 displays, for example, an error screen 503 shown in FIG. 6(c) on the operation panel 101. Here, the control unit 110 detects the reason why the print head 105 does not move, and displays a support number according to the reason on the error screen 503. Note that the printing device 100 according to this embodiment holds in advance a table in which the reason of the error is associated with the support number, and the table is stored in the ROM of the data storage unit 112. S405 in FIG. 5 is the same as S204 in FIG. 3. Note that, in this embodiment, the support number is not displayed on the guide screen displayed in S405, but the support number may also be displayed on the guide screen to provide the user with more detailed instructions on how to remove the packaging material based on the support number.

[0033] As described above, according to this embodiment, a screen showing the details of an error according to the number of times an error has been detected is displayed on the operation panel 101, so that the user can properly remove the packaging material.

[0034] (Other embodiments) In the first embodiment described above, when access cover opening / closing sensor 131 detects in S203 and S204 that access cover 102 is closed, the process returns to S201. Alternatively, the process may be returned to S201 when the user presses the OK button on the screen shown in Fig. 6. This allows guide screen 501 to remain displayed, for example, even if the user touches access cover 102 immediately after guide screen 501 is displayed on operation panel 101, causing it to open for a moment and then close.

[0035] Similarly, in the third embodiment described above, in S404 to S406, the process may be returned to S201 by the user pressing the OK button on the screen shown in Fig. 6. For example, even if the user touches the access cover 102 immediately after the error screen 502 is displayed on the operation panel 101 and opens it for a moment and then closes it, it is possible to prevent the screen from switching to the error screen 503.

[0036] In the third embodiment described above, the screen displayed is changed depending on whether an error has been detected once or twice or more times after the access cover 102 has been opened and closed, but the screen displayed may be changed in multiple stages. For example, if an error has been detected twice, an error screen 503 as shown in Fig. 6(c) may be displayed, and if an error has been detected three or more times, a screen with more emphasis may be displayed. In this case, the screen with emphasis may be any screen, such as one that uses easy-to-understand illustrations or text.

[0037] Furthermore, the second and third embodiments described above may be combined. For example, if the open time of access cover 102 is less than a predetermined value when opening and closing after error screen 502 is displayed on operation panel 101, the error may not be counted as the number of times an error has been detected, and error screen 502 may continue to be displayed. This allows an appropriate error screen to be displayed even if the user touches access cover 102, opens it for a moment, and then closes it.

[0038] In the above description, in S202, it is determined whether the access cover 102 is opened or closed after the power is turned on, but the present invention is not limited to this embodiment. In the above embodiment, if the access cover 102 is not opened or closed after the power is turned on, it is considered that the error that occurred is the first one. However, if the access cover 102 is opened or closed while a process such as a language setting process, a usage environment setting process, or a date and time setting process, which is a process included in the initial setting and is a process preceding the packing material removal confirmation process, is being executed, the access cover 102 is opened or closed after the power is turned on, even though the error that occurred is the first one. Therefore, in the above embodiment, even though the error that occurred is the first one, an error screen is displayed. Therefore, for example, S202 may be a process of determining whether the error related to the print head detected in S201 is a second or subsequent error. In this embodiment, when an error related to the print head is detected, the printing device 100 manages how many errors the detected error is. Also, for example, when an error related to the print head is detected, the printing device 100 manages whether the detected error is a first error or a second or subsequent error. Also, for example, S202 may be a process of determining whether or not the access cover 102 has been opened or closed after the process preceding the packing material removal confirmation process has been completed.

[0039] Also, in the above description, a form has been described in which the screen displayed when an error related to the print head is detected for the first time before the initial settings are completed is different from the screen displayed when an error related to the print head is detected for the second or subsequent times. However, this is not limited to this form. For example, a form may be different between the screen displayed when an error related to the print head is detected for the second or subsequent times before the initial settings are completed and the screen displayed when an error related to the print head is detected for the third or subsequent times. In other words, it is sufficient that the screen displayed when an error related to the print head occurs is different depending on the number of times, and the threshold value of the number of times for switching the screen to be displayed may be any value.

[0040] In the above description, the display of the guide screen or the error screen when an error related to the print head occurs is switched depending on the number of times the error occurs. However, the present invention is not limited to this. For example, the display of the guide screen or the error screen when an error other than an error related to the print head occurs may be switched depending on the number of times the error occurs. An error other than an error related to the print head is, for example, an error in which an ink cartridge is not installed in the printing device 100, which is an error that can be detected in the ink cartridge detection process. For example, when a cover open error occurs, the guide screen or the error screen may be displayed uniformly regardless of the number of times the error occurs. A cover open error is an error in which the cover of the printing device 100 is opened by the user during the initial setting and at a timing other than the timing during the packing material removal confirmation process and the ink cartridge detection process. When the cover is opened, the printing device 100 moves the print head from the standby position to the printing position. The user may intentionally open the cover frequently to check whether the packing material has been removed or whether the ink cartridge has been installed in the printer head. In other words, the occurrence of multiple cover open errors may be intentional on the part of the user. Therefore, in this embodiment, control is performed so that a guide screen is displayed uniformly for cover open errors, regardless of the number of times the error has occurred.

[0041] The states expressed as errors above can also be expressed as simple states that are not errors.
