Description

  The present invention relates to an image processing apparatus, a power saving mode control method, and a power saving mode control program, and in particular, an image processing apparatus having a plurality of modes with different power consumption as a power saving mode, and a power saving mode for controlling the power saving mode. The present invention relates to a control method and a power saving mode control program.

  An image processing apparatus such as an MFP (Multi-Functional Peripherals) is controlled to shift to a power saving mode when there is no operation or no job for a certain period of time in the standby mode. The technology regarding the transition timing to is widely known. The power saving mode includes a mode that consumes less power than the standby mode (referred to as a sleep mode) and a mode that consumes less power than the sleep mode (referred to as a deep sleep mode). The sleep mode is a mode in which, for example, the MFP panel is turned off to reduce power consumption. The deep sleep mode is, for example, a CPU (Central Processing Unit) clock frequency is lowered or a fixing device heater is turned off. In this mode, power consumption is reduced.

  As for the power saving function of the MFP, a weekly timer (hereinafter abbreviated as WT) function is known. This WT function sets the date and time to enter the sleep mode and deep sleep mode in advance, and performs control to shift to the sleep mode and deep sleep mode when the set date and time are reached.

  As a technology related to such a power saving mode of the MFP, for example, in Patent Document 1 below, a plurality of terminal devices and one or a plurality of image forming apparatuses that switch a power state between a power saving mode and a normal mode are provided via a network. In a connected electronic conference system, information related to an event such as the start / end of an electronic conference and timing information including an elapsed time after the execution of the event is input to a predetermined terminal device in the terminal device When the event is executed and the time corresponding to the event has elapsed, the predetermined terminal device to which the timing information has been input further changes the power state of the image forming apparatus from the power saving mode to the image forming apparatus. A command for shifting to the normal mode is transmitted, and the image forming apparatus in the power saving mode that has received the command is switched to the normal mode. Configuration is disclosed in which changing.

  Patent Document 2 below discloses a control unit that controls switching between a standby mode in a state where image formation is possible and a sleep mode in which power consumption is smaller than that in the standby mode and image formation cannot be performed, User information acquisition means for acquiring information relating to a user located in the specific area set to the first, wherein the control means prioritizes user convenience over power saving in the sleep mode. Either the control mode or the second control mode that prioritizes power saving over the convenience of the user can be selected, and switching between the first control mode and the second control mode can be performed by acquiring the user information. An image forming apparatus is disclosed which is performed based on information acquired by the means.

  Japanese Patent Application Laid-Open No. 2004-259542 discloses a calculation unit that calculates the number of print instructions that have been made within a predetermined period of time after the device has shifted to the power saving mode, and whether the number of print instructions in a predetermined setting period exceeds a reference value. A determination unit for determining, and when the number of print instructions exceeds the reference value, the shift period to the power saving mode is positively corrected, and when the number is less than the reference value, the shift period to the power saving mode is negatively corrected. An image forming apparatus including a correction unit is disclosed.

  The power saving function described above controls the transition to the power saving mode based on the operation status, job processing status, preset date and time, etc., but the type of user who uses the MFP and the usage mode of the MFP (for example, , Settlement methods), places of use, and the like, and it is difficult to appropriately control the power saving mode.

  With respect to this problem, in Patent Document 1 described above, the transition timing to the power saving mode is controlled based on the timing information including the elapsed time after the start of the execution of the event. Since it is premised that the progress contents and the time allocation are already known, it cannot be used to control an MFP installed in an environment where the schedule is not fixed. Further, in Patent Document 2, since a person in a specific area is the number of people who can log in, it cannot be used to control an MFP installed in an environment where the area is not fixed. Further, in Patent Document 3, the transition period to the power saving mode is corrected based on the number of print instructions. However, this technique is control based on history information, and in an environment where various types of users are mixed. It cannot be used to control the installed MFP.

  In addition, the weekly timer function is a function that prohibits the use outside of a predetermined time, and this function can be used only by employees, such as an MFP installed in the company, and it is prohibited to use other than work. It is effective in an environment where However, MFPs that can be used by various types of users such as teachers, staff, and students, such as MFPs installed in school facilities such as universities and high schools, or installed in public facilities such as government offices and libraries As described above, the weekly timer function cannot be used in an environment where various types of users such as staff and visitors are available and use other than work is not prohibited.

  In other words, the conventional technology is effective in an environment in which the user type, usage pattern (for example, payment method) and usage location can be determined (so-called closed environment), but the user type, usage pattern, and usage location cannot be determined. In (so-called open environment), even when these technologies are used, it is not possible to appropriately control the timing of shifting to the power saving mode.

  The present invention has been made in view of the above-mentioned problems, and its main purpose is to appropriately select a power saving mode according to the type of the user who uses the apparatus, the usage form (settlement method) of the apparatus, and the usage location. It is an object to provide an image processing apparatus, a power saving mode control method, and a power saving mode control program.

  One aspect of the present invention is an image processing apparatus installed in a predetermined location that can be used by a plurality of types of users, and user information that defines a usable time zone for each user type from a predetermined storage device And an information acquisition unit that acquires, based on the user information at a predetermined time interval, a determination unit that determines, for each user type, whether the current time is a time zone that can be used by a user of the user type When the standby mode state continues for a predetermined time, the mode is shifted to the first power saving mode that consumes less power than the standby mode, and when the first power saving mode state continues for the predetermined time, the first An operation control unit that shifts to a second power saving mode that consumes less power than the power saving mode, wherein the operation control unit is configured to perform the second power saving mode based on a determination result of the determination unit. Control migration And wherein the Rukoto.

  One aspect of the present invention is a power saving mode control method in an image processing apparatus installed in a predetermined location that can be used by a plurality of types of users, and the time available for each user type from a predetermined storage device Whether the current time is a time zone that can be used by a user of the user type for each user type based on the user information at a predetermined time interval and information acquisition processing for acquiring user information that defines a zone When the state of the standby mode continues for a predetermined time, the state is shifted to the first power saving mode in which the power consumption is lower than that of the standby mode, and the state of the first power saving mode continues for the predetermined time. When shifting to the second power saving mode in which the power consumption is smaller than that of the first power saving mode, the transition of the second power saving mode is controlled based on the determination result of the determination process. An operation control process that is characterized by a run.

  One aspect of the present invention is a power saving mode control program that operates in an image processing apparatus installed in a predetermined place that can be used by a plurality of types of users, and that stores a predetermined storage in the control unit of the image processing apparatus. An information acquisition process for acquiring user information that defines a usable time zone for each user type from the device, based on the user information at a predetermined time interval, the current time of the user type A determination process for determining whether or not the user is in a usable time zone, and when the standby mode state continues for a predetermined time, the first power saving mode in which the power consumption is smaller than that in the standby mode is shifted to the first mode. When shifting to the second power saving mode in which the power consumption is lower than that in the first power saving mode when the power saving mode state continues for a predetermined time, based on the determination result of the determination processing, Operation control process of controlling the migration of the second power saving mode, characterized in that to the execution.

  According to the image processing apparatus, the power saving mode control method, and the power saving mode control program of the present invention, the power saving mode is appropriately selected according to the type of the user who uses the apparatus, the usage form (settlement method) of the apparatus, and the usage location. Can be controlled.

  The reason is that an image processing apparatus (a power saving mode control program that operates in the image processing apparatus) installed in a predetermined place where a plurality of types of users can use is used from a predetermined storage device for each user type. User information that defines the available time zone (or available time zone and available payment method, or available time zone and available usage location) is acquired, and the acquired user information at a predetermined time interval For each user type, whether the current time is a time zone that can be used by a user of the user type (or a time zone that can be used by a payment method that can be used by a user of the user type, or The first power saving that consumes less power than the standby mode when the standby mode state continues for a predetermined period of time. When the operation control is performed to shift to the second power saving mode in which the power consumption is lower than that of the first power saving mode when the mode is shifted to the mode and the state of the first power saving mode continues for a predetermined time. This is because the transition of the second power saving mode is controlled based on the result.

It is a figure explaining the solution of case 4.

As shown in the background art, an image processing apparatus such as an MFP can operate in a power saving mode (Sleep mode or standby mode) when a normal operation mode (normal mode or standby mode) continues for a certain period of time without operation or no job. By shifting to the Deep Sleep mode, power consumption is reduced, and various techniques have been proposed regarding the timing of shifting to the power saving mode.

  Here, in order to reduce the power consumption, it is only necessary to control so as to frequently shift to the power saving mode. Usually, the MFP returns from the power saving mode to the normal mode for about 30 seconds to 5 minutes. Since time is required and the user is kept waiting during that time, it is inconvenient when quick printing is required. FIG. 21 is a diagram illustrating a relationship between the state of the MFP and power consumption. As shown in FIG. 21 (a), when the MFP is processing a job or starting up, each part of the engine (exposure device, developing device, fixing device, etc.) is operated and the panel is turned on. Is a large value, but when there is no operation or no job for a certain period of time, it enters a standby state, and the power consumption can be reduced by mainly suppressing the operation of the engine. Furthermore, when the standby state continues for a certain time, it becomes a sleep state, for example, it is possible to reduce the power consumption by turning off the power of the panel, and when the sleep state continues for a certain time, it becomes the deep sleep state. The power consumption can be reduced by lowering the clock frequency of the CPU or turning off the heater of the fixing device.

  Regarding the transition of the operation mode, when shifting from the operation mode with high power consumption to the operation mode with low power consumption, basically the function and power supply of the device are simply turned off, so the transition time of the operation mode is short. (The fall in FIG. 21A is almost vertical), but when returning from an operation mode with low power consumption to an operation mode with high power consumption, not only the function and power supply of the device are turned on, but also the operation Since it is necessary to wait until it stabilizes, the transition time of the operation mode becomes long (the rising in FIG. 21A is inclined). For example, to return from the Deep Sleep mode to the normal mode, increase the CPU clock frequency, turn on the heater of the fixing device to increase the temperature, turn on the panel power, and display the operation screen on the panel. It takes time for the CPU clock frequency to stabilize, the heater of the fixing device to reach a certain temperature, and the panel to become operable. Similarly, when returning from the sleep mode to the normal mode, it is necessary to turn on the panel and display the operation screen on the panel, and it takes time until the panel becomes operable. Therefore, when controlling the power saving mode, it is necessary to consider a time lag until the normal mode or the standby mode is restored.

  The above is a method for shifting the operation mode according to the state of the MFP. However, when shifting the operation mode based on the date and time, a WT (Weekly Timer) function can also be used. FIG. 22 is a setting example of the WT function. For example, when the WT application range is set from 12:00 to 15:00, the standby mode is changed to the Deep Sleep mode at 12:00, and the Deep Sleep mode is changed to the standby mode at 15:00. Migrate to

  This WT function is a method for designating the date and time, but when an event is started, the operation mode of the MFP can be controlled in accordance with the time schedule of the event. For example, in Patent Document 1, when the normal mode transition timing management unit in the electronic conference server used in the electronic conference system receives event information, the time in the time information column of the timing information recording table corresponding to the event information is monitored. When the time elapses, a normal mode transition instruction command is transmitted to the MFP. When the power saving control unit of the MFP receives the normal mode transition instruction command, when the MFP is in the power saving mode, the power saving mode is changed to the normal mode. I try to migrate.

  The power saving mode can be controlled by using such a WT function and the technology disclosed in Patent Document 1. However, as described above, until the operation mode with low power consumption returns to the operation mode with high power consumption. Therefore, it is necessary to control the power saving mode in consideration of this time lag.

  Here, when the purpose of the participant such as an electronic conference is determined, or when the progress of the conference and the time distribution are known in advance, it is not possible to appropriately manage the power state of the MFP over time. Although it is possible, in an environment (open environment) where the purpose of use of the user is not determined, such as an MFP installed in a school facility or public facility, a timing information recording table as in Patent Document 1 is used. Therefore, it is impossible to appropriately control the power state of the MFP, that is, the transition timing to the power saving mode and the transition timing from the power saving mode. Furthermore, there is a demand for an MFP placed in an open environment to switch the power saving mode according to the time depending on the type of user who uses the apparatus, the type of use of the apparatus (for example, payment method), the place of use, and the like.

  Therefore, in an embodiment of the present invention, in an image processing apparatus having a power saving mode, user information associated with an available time zone, a payment method, a use place, and the like is managed for each user type, and the user information is stored in the user information. Based on this, it is determined whether it is time to use the image processing apparatus, thereby appropriately controlling the transition to the power saving mode. Specifically, user information that defines a usable time zone (or a usable time zone and a usable payment method, or a usable time zone and a usable place of use) for each user type from a server or the like. For each user type, whether the current time is a time zone that can be used by the user of the user type (or can be used by the user of the user type) at predetermined time intervals based on the acquired user information Whether it is a time zone that can be used with a simple settlement method, or a time zone that can be used in a place where a user of the user type can use), and based on the determination result, the second saving Control power mode transitions.

  Regarding the above control, the following four cases will be specifically described.

<Case 1: Pattern 1>
As shown in FIG. 23, since it takes time until the MFP shifts from the deep sleep mode to the standby mode, the power saving time is low when there are many users who can use the MFP or when a specific user can use the MFP. You may not want to enter the mode (Deep Sleep mode). In this case, as shown in FIG. 24, in the transition control from the sleep mode to the deep sleep mode, when the number of users is large or a specific user is usable (for example, when a student is usable), Deep Sleep The sleep mode is maintained without shifting to the mode, and the waiting time when the user uses the MFP is shortened. That is, when it is a time zone in which a user of any user type can use, control for prohibiting the transition to the deep sleep mode is performed even at the timing of transition from the sleep mode to the deep sleep mode.

<Case 1: Pattern 2>
As shown in FIG. 25, when performing control to shift to the Deep Sleep mode using the WT function or the like, the time zone of the WT application range (here from 12:00 to 14:00) depends on the number of users and the type of user. Regardless of the transition to Deep Sleep mode. In this case, as shown in FIG. 26, after the transition to the Deep Sleep mode, when the number of users is large or a specific user can use the time zone (for example, in the time zone from 14:00 to 15:00) When it can be used, the Deep Sleep mode is shifted to the Sleep mode, and the waiting time when the user uses the MFP is shortened. That is, during the Deep Sleep mode, when it becomes a time zone in which any type of user can use, control is performed to shift from the Deep Sleep mode to the Sleep mode.

<Case 2>
As shown in FIG. 27, there is a case where it is desired to reduce power consumption in a time zone where all users are prohibited from using the MFP even when the WT function is not applied. In this case, as shown in FIG. 28, during the time period when there is no user who can use the MFP, the mode shifts to the Deep Sleep mode, and the power consumption is suppressed. In other words, during a mode other than the Deep Sleep mode, when it becomes an unusable time zone for all types of users, control is performed to shift from the other mode to the Deep Sleep mode.

<Case 3>
As shown in FIG. 29, when the payment method of the MFP is fixed, the power saving mode cannot be set. In this case, as shown in FIG. 30, the MFP that is permitted to be used only for post-charging (counter charging) is shifted to the sleep mode by looking at the payment method for each user time zone, and pre-charging (coin The MFP that is permitted to be used only by the vendor) has a time for inserting a coin into the coin vendor, and therefore allows the transition to the Deep Sleep mode. In other words, during any mode other than Deep Sleep mode, if any type of user is in a time zone that can only be used for post-billing, control to prohibit the transition from other modes to Deep Sleep mode is performed. Do.

<Case 4>
As shown in FIG. 31, the power saving mode cannot be set when the use place of the MFP is fixed. In this case, as shown in FIG. 32, the MFPs that are permitted to be used only in places (for example, co-ops) that are used by an unspecified number of people are viewed up to the sleep mode by looking at the use places for each user time zone MFPs that are permitted to be used only in places (for example, laboratories) that are used by a small number of people are allowed to transition to Deep Sleep mode because MFPs are used less frequently than co-ops. . In other words, during any mode other than Deep Sleep mode, if any type of user is in a time zone that can be used at the MFP installation location, control to prohibit the transition from other modes to Deep Sleep mode I do.

  By performing such control, even in an MFP placed in an open environment that is used by various users, it is possible to appropriately control the transition to the power saving mode. Further, it becomes easier for the MFP administrator to manage the MFP, and usability can be improved. Although the above effect can be obtained in the power saving mode control of the MFP placed in an arbitrary open environment, in the following embodiment, the power saving of the MFP placed in a university where students, staff and teachers are mixed. Mode control will be described.

  In order to describe the above-described embodiment of the present invention in more detail, an image processing apparatus, a power saving mode control method, and a power saving mode control program according to an embodiment of the present invention will be described with reference to FIGS. explain. FIG. 1 is a schematic diagram illustrating a configuration of a printing system according to the present exemplary embodiment, and FIG. 2 is a block diagram illustrating a configuration of an image processing apparatus. FIG. 3 is a table showing an example of a card used for controlling the power saving mode of this embodiment, and FIG. 4 is a table showing an example of user information used for controlling the power saving mode of this embodiment. It is. FIG. 5 is a schematic diagram for explaining sharing of user information, FIG. 6 is a table showing an example of machine specific information used for controlling the power saving mode of the present embodiment, and FIG. It is a table which shows a determination matrix. 8, 9, 11, 13, 15 to 20 are flowcharts showing the processing of the image processing apparatus of the present embodiment, and FIGS. 10, 12, and 14 are the determinations of FIGS. 9, 11, and 13, respectively. It is a table which shows a result.

  As shown in FIG. 1A, the printing system according to the present exemplary embodiment includes one or a plurality of image processing apparatuses 10 such as MFPs. The plurality of image processing apparatuses 10 include Ethernet (registered trademark), token ring, They are connected via a communication network 40 such as a LAN (Local Area Network) or a WAN (Wide Area Network) defined by a standard such as FDDI (Fiber-Distributed Data Interface). In FIG. 1A, the printing system is composed of one or a plurality of image processing apparatuses 10. However, as shown in FIG. 1B, a server 30 that holds user information is provided via a communication network 40. It is good also as a structure connected.

  As shown in FIG. 2A, the image processing apparatus 10 according to this embodiment includes a controller (control unit) 11, a storage unit 15, a panel (display operation unit) 16, an image processing unit 17, and an image reading unit (scanner). 18, a printing unit (engine) 19, a post-processing unit 20, a network I / F unit 21, a USB I / F unit 22, a serial I / F unit 23, and the like.

  The controller 11 includes one or a plurality of CPUs 12 (here, a multi-core CPU including four CPUs) and a memory such as a ROM (Read Only Memory) 13 and a RAM (Random Access Memory) 14. The operation of the entire image processing apparatus 10 is controlled by developing the control program stored in the storage unit 15 in the RAM 14 and executing it.

  As shown in FIG. 2B, the controller 11 functions as an information acquisition unit 11a, a determination unit 11b, an operation control unit 11c, and the like.

  The information acquisition unit 11a serves as a master unit for information (hereinafter referred to as user information) that defines a usable time zone for each user type and a settlement method that can be used or a usable place where necessary. It is acquired from the image processing apparatus 10 or the server 30 and stored in the storage unit 15 and managed. The user type is a grouped user type. In this embodiment, the user type is a university student, a staff member, or a teacher, but this type can be arbitrarily set. When user information is added / updated / deleted, the addition / update / deletion of user information is shared between the image processing apparatuses 10 connected via the network or between the server 30 and the image processing apparatus 10. That is, when the MFP or the server 30 serving as the master unit receives a notification of addition / update / deletion of user information from any of the image processing apparatuses 10, the user added / updated / deleted to the other image processing apparatus 10 Distribute information. The user information acquisition method is not particularly limited. For example, MIB (Management Information Base) information disclosed by a network device managed by SNMP (Simple Network Management Protocol) is used to inform the outside of the user's state. Can be obtained. The information acquisition unit 11a also stores information on machine specific information (for example, installation location code, presence / absence of pre-charging device, etc.) that is not shared between the image processing apparatuses 10 or between the server 30 and the image processing apparatus 10 in the storage unit 15 or the like. Remember and manage.

  Based on the user information and machine-specific information managed by the information acquisition unit 11a, the determination unit 11b determines whether the current time is a time zone in which a user of the user type can use the user type, It is determined whether it is a time zone that can be used by a payment method that can be used by a user, or a time zone that can be used at a usage place where a user of the user type can use.

  When the state of the standby mode continues for a predetermined time, the operation control unit 11c shifts to the sleep mode (first power saving mode) in which the power consumption is lower than that of the standby mode, and the state of the sleep mode mode continues for the predetermined time Then, operation control is performed to shift to the Deep Sleep mode (second power saving mode), which consumes less power than the Sleep mode. Further, when the panel 16 is operated or a job is received in the standby mode, sleep mode, or deep sleep mode, operation control for returning to the normal mode is performed. At that time, the transition to the Deep Sleep mode is controlled based on the determination result of the determination unit 11b.

  Specifically, when it becomes a time zone that can be used by any user or a specific user type, the transition to the Deep Sleep mode is prohibited even at the timing of transition from the Sleep mode to the Deep Sleep mode. . Also, during the Deep Sleep mode, when it becomes a time zone in which any one or a specific type of user can use, the Deep Sleep mode is shifted to the Sleep mode. In addition, during a mode other than the Deep Sleep mode, when it becomes a time zone in which all types of users cannot be used, the mode is shifted from the other mode to the Deep Sleep mode. Also, during any other mode other than Deep Sleep mode, if any or a specific type of user is in a time zone that can only be used for post-billing (counter billing), switching from other modes to Deep Sleep mode Prohibit migration. In addition, during any mode other than the Deep Sleep mode, if any or a specific type of user enters a time zone in which the image processing apparatus 10 can be used, the mode is changed from the other mode to the Deep Sleep mode. Prohibit migration.

  First, the overall flow will be described with reference to FIG.

  The controller 11 (determination unit 11b) acquires the current time a of the MFP (S101). Next, the controller 11 (determination unit 11b) acquires the job status of the MFP (S102), and waits for completion of job execution. Next, the controller 11 (determination unit 11b) acquires the power state (current operation mode) of the MFP (S104), and determines whether it is a transition state from the sleep mode to the deep sleep mode (S105). If the state is not a transition state from the Sleep mode to the Deep Sleep mode (No in S105), the controller 11 (determination unit 11b) acquires the current time b of the MFP (S106). The controller 11 (determination unit 11b) determines whether the current time a is greater than the current time b (S107). If the current time a is less than or equal to the current time b (S107). No), returning to S101, the same processing is repeated. Note that the comparison of the minute of the current time a and the minute of the current time b in S107 is performed at a predetermined time interval (timing when the minute of the current time b becomes “00” minutes). For example, S101 may be omitted, and the processing after S108 may be executed when the current time acquired in S106 reaches “00” minutes.

  When it is determined that it is a transition state from the sleep mode to the deep sleep mode (Yes in S105), or when the current time a is greater than the current time b (Yes in S107), the controller 11 (determination unit) 11b) obtains the “power saving mode” information of the user information (information in the “power saving mode” column in the “user information setting value” in FIG. 7) (S108). Then, when the information of the “power saving mode” is “user only” (Yes in S109), the controller 11 (operation control unit 11c) executes the process (a) shown in the flowchart of FIG. In the case of “user + settlement method” (Yes in S110), the process of (b) shown in the flowchart of FIG. 16 is executed. In the case of “user + use place” (Yes in S111), the flowchart of FIG. (C) shown in FIG. If the information of “power saving mode” does not correspond to any of the above (No in S109, No in S110, No in S111), No. in FIG. Therefore, the controller 11 (operation control unit 11c) shifts the power state of the MFP to the Deep Sleep mode (S112), returns to S101, and repeats the same processing.

  Next, the processes (a) to (c) will be described. The “MFP usable time zone”, “Determined available payment method”, and “Usable use” are common to the processes. The “location determination” will be described first. These processes are executed by the controller 11 (determination unit 11b).
