Description

  The present invention relates to an electronic device that can communicate with a time information supply device that supplies time information, a control method for the electronic device, a program, and a storage medium.

  Built-in functions to adjust the time of the internal clock using a time service using the Internet, a time service using radio waves, and a time service using a broadcast time signal (using time information supplied from outside) An apparatus has been proposed (see, for example, Patent Documents 1 and 2 below).

  There are many devices that use such a time service, but there are only a few devices that actively use the set time simply by incorporating a function for setting the time.

  In addition, as various information is digitized, detailed information management such as creation time and modification time of digitized data is required. For example, when there are multiple pieces of the same digital data, Such date and time information is important information for judgment.

JP-A-8-16528 JP 2000-131471 A

  A device that automatically calibrates the built-in timekeeping function using the time service as described above can reduce the burden of time adjustment on the device user. I think there are some problems regarding whether it can be maintained.

  For example, a device that can use a time service as described above may or may not have a function for an operator to manually set the date and time for the device. However, if such a function is installed in the device as described above, the time service function will function correctly if the operator makes an input error or intentionally changes the date and time. There may be a problem such as an uncertain time setting state in which correct date information cannot be guaranteed until the date is set.

  In addition, when the time service cannot be used for a long time for some reason, the date and time may be unreliable depending on the accuracy of the built-in clock function.

  In addition, the conventional proposal focuses only on enabling operation based on accurate time information using a time service. For example, when a user who is not familiar with the operation of such a device uses it. However, there is a situation where the time service cannot be used due to some circumstances (or a situation where the time service can be used but not actually used) if it can be properly dealt with. How do you do not have to deal with anything when it happens (or can happen), whether you want to prohibit the use of the device itself, or make it operable with some restrictions? What should be addressed, what is the best way for the user of the device, how to improve usability, etc. It has not been fully addressed.

  Even if a device can use a time service, the processing that can be executed for each device and the functions that the device has are considered to be diverse. When the time service function is installed, such as when it is applied to a forming device, it is more convenient to consider a device that is specific to the device's capabilities and usage environment than to simply install the time service. In addition, take into account the features of the device, usage status, usage environment, etc., such as what functions the device has, what kind of processing is possible, and how it is used by users. Thinking about the design / specification can provide a user-friendly device / system that is more user-friendly and will also lead to practical application.

  As described above, there are still many situations and problems to be considered when trying to actually put into practical use a device / system that makes it possible to use time information supplied from outside such as the time service described above. It would be desirable to have something that has been carefully examined and dealt with.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to solve the above-described problem occurrence and to use time information supplied from the outside such as a time service. An electronic device that can deal with situations and problems that are likely to occur when the device is actually put into practical use, and can be further improved in usability from the standpoint of the user, and an electronic device control method and The purpose is to provide a program.

  Further, in addition to the above-mentioned object, the present invention also makes it possible to record the state of the set time in an identifiable manner when leaving a record of the operation, so that the time is reliable and the case where it is not is determined later. It is an object of the present invention to provide an electronic device that can be enabled and a control method and program for the electronic device.

  The present invention has the following characteristic configuration.

  An electronic device that executes data processing, a communication unit that communicates with a time information supply device that supplies time information, and a first setting that sets time according to first time information supplied from the time information supply device Means, second setting means for setting time according to second time information set by a user without using the time information supply device, and time by the first setting means when data processing is executed. Holding means for holding log information of the data processing executed by the electronic device so that it can be identified whether the time is set by the second setting means or the time is set by the second setting means It is characterized by having.

  A method for controlling an electronic device that executes data processing, comprising: a first setting step for setting time according to first time information supplied from a time information supply device that supplies time information; and the time information supply device. A second setting step for setting the time according to the second time information set by the user without using it, and whether the time is set by the first setting means when the data processing is executed A holding step of holding in the holding unit log information of the data processing executed by the electronic device so that it can be identified whether the time is set by the second setting unit. And

  A program that causes a computer to execute the above control method.

  A storage medium that stores the above-described program.

  According to the present invention, when a device that can use time information supplied from the outside such as a time service is actually put into practical use, the situation / problem that is likely to occur in reality is addressed by the user. It is possible to improve usability from the standpoint.

  When leaving a record of the operation, the state of the set time is recorded so as to be identifiable, so that the state in which the time is reliable and the case where it is not can be distinguished later.

  Hereinafter, in the present embodiment, an electronic device that performs Internet facsimile communication as an electronic device having a built-in time setting service function (note that an electronic device is sometimes also referred to as an information processing device or an image forming device, and is simply referred to as a device). Will be described as an example.

  In the present embodiment, the time setting service uses a service via the Internet. The time setting service via the Internet can synchronize all the information of the year, month, day, time, and is suitable as an embodiment of the present invention.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of an Internet facsimile machine to which an electronic apparatus showing a first embodiment of the present invention is applied.

  In FIG. 1, reference numeral 11 denotes an Internet facsimile body (Internet facsimile), which is connected by a CPU bus 12, and includes a CPU 21, RAM 22, a hard disk drive (hereinafter referred to as HDD) 23, a network card 24, a display unit 25, a key operation unit 26, and a document. A scanner unit 27 that performs reading, a printer unit 28 that performs printing, and the like.

  The CPU 21 measures time by counting clocks generated by the internal oscillator. The timing information is stored in the RAM 22 and displayed on the display unit 25 as necessary.

  The Internet facsimile machine 11 of this embodiment is connected to the Internet 13 via a network card 24. The Internet facsimile main body 310 (another Internet facsimile apparatus capable of data communication of its own device, also simply called a partner) is a device that performs a communication operation with the Internet facsimile main body 11, and has the same configuration and function as the apparatus of the present embodiment. The communication operation flow of both devices will be described later.

  Further, the Internet facsimile machine 11 has a built-in function capable of synchronizing the time by connecting to the time service server 14 such as “time.nist.gov” and “time.windows (registered trademark) .com”.

  The time service server 14 via the Internet incorporates an accurate clock and supplies date and time information via the Internet facsimile main body 11 and the Internet. The Internet facsimile 11 can obtain accurate date and time information in units of seconds each time a communication delay via the Internet is measured and corrected. The principle of such a time service server is widely known and will not be described in detail in this embodiment.

  The present invention can be applied to a time setting service using radio waves or telephones, but if it is simply synchronized with a time signal, it can be corrected when the manually set date is incorrect. There is inconvenience that there is not. In such a case, it is only necessary to change the setting of the apparatus so that a device that cannot be completely guaranteed, such as a manually set date, is assumed to be correct. The present embodiment does not limit the present invention according to the type of time setting service.

  As described above, the present embodiment is an apparatus (or system or the like) that can manually set time information by an operator, for example, via the operation unit, regardless of what communication medium or service is used, and The time information can be communicated with an external device capable of generating time information, and the time information supplied from the external device (or actively acquired from the external device) as the time information generation source is automatically and manually It can be applied to a device that can be selectively set in the apparatus.

  If the time information manually set by the user of the apparatus through the operation unit or the like is used as the first type time data, the aging obtained from the outside of the time information generation source is used. The information is second type time data. On the contrary, if the aging information acquired from the outside as the time information generation source is the first type time data, the time information manually set by the user of the apparatus through the operation unit or the like in the own apparatus. Is the second type time data. It may be applied to either case.

  In the present embodiment, the time information includes a plurality of types such as year data specifying the year of the year, date data specifying the month and date, time data specifying the hour, minute, and second. A case where a time element is included will be described as an example. However, the present embodiment is not limited to this, and other time elements (day of the week data specifying the day of the week) may be included. Only a part of the time elements (for example, only three types of time elements of year data, date data, and time data) may be included.

  Of these various time elements, some (eg, year data and date data) use time information set by the device, and another part (eg, time data) generates external time information. You may comprise so that the information acquired from the source may be utilized.

  And this embodiment presupposes the above-mentioned composition, while being able to execute processing and functions based on time information (first type time data) set via the operation unit of its own device, Processing / function based on time information (second type time data) acquired from an external time information generation source can be executed, and any type of time data is not registered and set in the own device. However, it can be applied to an apparatus / system having an executable process or function (time data not yet set).

  As described above, the apparatus (system) of the present embodiment can operate according to the manually set time data, can operate according to the automatically set time data, and can be operated manually or automatically. Operation is possible even when information is not set. Under such a configuration, the state of the apparatus (whether the first type time data is set or the second type time data is set) Related information is stored and retained in the memory so that it can be distinguished whether the first time data or the second time data is not set), and according to the information (time data setting status) In addition, it is configured to be controllable so as to dynamically switch the display contents of the operation screen of the operation unit serving as the user interface with the user, and the function / process for permitting / prohibiting execution.

  FIG. 2 is a flowchart showing an example of a first data processing procedure in the electronic apparatus according to the present invention, and corresponds to an operation procedure related to date / time information setting of the Internet facsimile 11, for example. SP1 to SP14 indicate each step.

  The processing of various flowcharts described in this embodiment including this flowchart is performed by a desired program from a memory (not shown) in which the CPU 21 of this apparatus stores a program for executing the processing of each flowchart of this embodiment. However, the present embodiment can be applied even if any unit of any device functions as a control unit for executing the processing of the present embodiment.

  When the Internet facsimile 11 is turned on, in step SP1, the CPU 21 initializes the internal parameters STS and MD stored in the RAM 22 to “0”.

  The parameter STS is a parameter that holds the date / time setting state in the apparatus. When STS = 0, this indicates a state in which the date and time are not set when the apparatus is turned on. When STS = 1, this indicates the state where the date / time information has been manually set (in this case, there is a possibility of an input error). When STS = 2, the connection to the time service server 14 was successfully completed. Indicates the state.

  When STS = 3, the time service server 14 cannot calibrate the date and time for a predetermined time interval or longer for some reason.

  In this embodiment, a plurality of types of status situations related to time information in this apparatus are prepared as described above, and the CPU 21 uses the STS parameter as information indicating the status of the time information in this apparatus, for example, as follows. Management control.

  For example, when it is determined by the detection signal from the operation unit that the time information (first type time data) is not set by the user via the operation unit of the apparatus, and the device and the data When it is determined by a detection signal from a predetermined unit such as the network card 24 that the time information (second type time data) output from a communicable external source is not income / set (calibrated) The CPU 21 regards the date / time information as unset / uncalibrated (time data not set) regardless of whether it is manual or automatic, and controls the value of the parameter STS in the memory to be “0”.

  When the CPU 21 determines from the detection signal from the operation unit that the time data (first type time data) has been set by the user via the operation unit of the apparatus, the CPU 21 notifies the apparatus of the date and time information. Is manually set (time data is manually set), and the data in the memory is updated so that the parameter STS is set to “1”.

  The automatic acquisition and automatic calibration processing of time data (second type time data) from an external time information generation source capable of data communication with this apparatus is judged by a detection signal from a predetermined unit such as the network card 24. In this case, the CPU 21 considers that the date and time information is automatically set (the time data is calibrated), and controls to rewrite the data in the memory so that the parameter STS is “2”.

  The network card 24 or the like is informed that there is a situation in which time data (second type time data) from an external time information source capable of data communication with this device cannot be automatically automatically acquired and calibrated. If it is determined based on a network communication error signal from the unit, the CPU 21 regards it as a date / time information calibration error (time data calibration required state) and rewrites the data in the memory so that the parameter STS is set to “3”. .

  Note that the status information (parameter STS value) related to the time setting in these apparatuses is used when the CPU 21 determines the display contents of an operation screen described later, whether to perform the following function restrictions, and the function restrictions. This is used when deciding which functions to restrict.

  The parameter MD is a parameter used when the Internet fax operation is restricted by the value of the parameter STS.

  The apparatus according to the present embodiment has a plurality of functions and operation modes such as an operation for transmitting job data input via the scanner unit to another apparatus and an operation for performing print processing on job data received from another apparatus by a printer unit. It has. In the present embodiment, in an apparatus having a plurality of functions / operation modes as described above, more accurate (high accuracy) time information is set for the apparatus in the plurality of modes. (Calibrated) In addition, if there is a function that can be expected to be more useful and effective if it is operated using this time information, high-accuracy time information is not necessary, but accurate time information to some extent There are functions that can be expected to be more user-friendly and effective, and there are functions that can fully demonstrate the effect without the need for time information itself. We focus on being.

  In view of such a situation, the present embodiment uses the parameter MD that can be set based on the value of the parameter STS to control the various functional operations of the apparatus to be executable. In this embodiment, for example, the following settings are used.

  When MD = 0, regardless of the value of the parameter STS (that is, regardless of the current setting status regarding the time data in the apparatus), the operation of a plurality of operation modes (also called functions) included in the apparatus is performed. Indicates that the operation mode without restriction is selected.

  In this situation (when MD = 0), regardless of the value of the STS, the CPU 21 performs a plurality of operation modes (external reception print for printing received job data) provided in the apparatus. Mode, multiple operation modes including external transmission mode for transmitting input job data to the outside), and control so that any operation mode can be selected by the user and execution of any mode is permitted. .

  When MD = 1, it is determined that the operation mode in which only the data reception operation is permitted is selected even when the value of the parameter STS is not “2” (in other words, when the value of the parameter STS is 0, 1 or 3). Show. In other words, even if the value of the parameter STS is 0, 1, 2, or 3, the execution of the data reception operation is permitted (other operation modes are prohibited), but the value of the parameter STS is “2”. "" Means that there is a mode (for example, a data transmission processing mode to another device) that permits execution in an operation mode other than the data reception operation, in addition to the data reception operation mode.

  In the case of this setting status (when MD = 1), for example, when the current operation status of the apparatus is in a state in which an operation based on time data (first time data) manually set from the operation unit is possible (When STS = 1), when neither manual / automatic time data is set (when STS = 0), or when calibration processing of time data from the outside is not executable (when STS = 0) In any one of the three operation situations (when STS = 3), the CPU 21 executes an operation (external reception print mode) in which job data output from the outside and received is printed by the printer unit. Control is performed so that execution of an operation mode other than the external reception print mode (for example, external transmission mode) is prohibited. In addition, in the case of this setting status (MD = 1), for example, when the current operation status of the apparatus is in a state in which an operation based on time data (second time data) from an external device is possible (STS) In the case of = 2), the CPU 21 permits the execution of the external reception print mode and prohibits the operation mode (for example, the external transmission mode) that has been prohibited in other operation situations (when STS = 0, 1 or 3). ) Is also permitted to be executed.

  When MD = 2, it indicates that an operation mode in which only the data transmission operation is permitted is selected even when the value of the parameter STS is not “2”. In other words, even if the value of the parameter STS is 0, 1, 2, or 3, execution of the data transmission operation is permitted (other operation modes are prohibited), but the value of the parameter STS is “2”. "Means that there is a mode (for example, an external reception print mode) that permits execution in an operation mode other than the data transmission operation, in addition to the data transmission operation mode.

  In the case of this setting status (when MD = 2), for example, when the current operation status of the apparatus is in a state in which an operation based on time data (first time data) manually set from the operation unit is possible (When STS = 1), when neither manual / automatic time data is set (when STS = 0), or when calibration processing of time data from the outside is not executable In any case (when STS = 3), the CPU 21 permits execution of the external transmission mode, and other operation modes other than the external transmission mode (for example, external reception print mode). Control to prohibit execution.

  In addition, in the case of this setting status (MD = 2), for example, when the current operating status of the apparatus is in a state in which an operation based on time data (second time data) from an external device is possible (STS) In the case of = 2), the CPU 21 permits the execution of the external transmission mode, and prohibits the operation mode (for example, the external reception print mode, for example) in other operation situations (when STS = 0, 1 or 3). ) Is also permitted to be executed.

  Such a summary of various situations / conditions / rules used as a judgment material when the CPU 21 executes various controls is stored in a memory (not shown) in a table format as shown in FIG. 13, for example. The information may be stored and held as management information, and the CPU 21 may appropriately read and execute the information according to the table information. Further, the value of the parameter MD may be configured to be set by an operator at the operation unit of the apparatus, or may be configured to be automatically set by the CPU 21 based on the value of the parameter STS managed by the CPU 21. good. In this case, based on the management information of the management table data 1300 in FIG. 13, the value of the parameter MD set and registered in the memory, and the value of the parameter STS, the CPU 21 operates as described above or in the operation mode of the present apparatus described later. Control is performed so as to determine whether execution is possible and restrictions on operation modes. Note that the restriction contents of the operation mode (the contents in the rightmost column in FIG. 13) may be appropriately changed by the user. Further, when a new function is added to the apparatus, a condition for the additional function may be set, and control may be performed so that the contents of the management table data 1300 are appropriately updated as management data reflecting the condition.

  As other setting examples and control examples, for example, the document 21 is permitted to be read during the data transmission operation, but the actual transmission is permitted when STS = 2, or the reception data is transferred to the HDD 23 during the reception operation. The temporary time is stored in advance, and when STS = 2, the difference between the corrected date and time is calculated, the time information of the received data is rewritten, and the received data is printed. May be controlled by the CPU 21. In this way, it may be configured to allow finer control.

  Thereby, even when only the date and time setting is not normal, it is possible to use the apparatus to some extent, and the effect of improving the operating rate of the apparatus is obtained in addition to the other effects according to the present embodiment.

  Here, FIGS. 3 to 6 show examples of the display unit 25 and the key operation unit 26 of FIG. 1 included in the apparatus of the present embodiment.

  3 to 6 are plan views showing an example of an operation panel unit including the display unit 25 and the key operation unit 26 shown in FIG. 1, and the same components as those in FIG. .

  The configuration of the operation panel of the present embodiment will be mainly described in the case where a soft key is provided on the display screen of the display unit 25 and the other (keys 31 to 38) are configured as mechanical hard keys. All the keys may be provided on the operation screen (all soft keys), or some of the hard keys (keys 31 to 33, etc.) shown in FIG. 3 may be installed as soft keys in the display screen. It may be configured. The present embodiment can be applied to any operation unit configuration.

  The display unit 25 shown in each drawing of FIGS. 3 to 6 is display-controlled by the CPU 21 described above, and the CPU 21 stores the value of the STS held in the memory according to various processes including the process of the flowchart of FIG. The display content to be displayed on the display unit 25 is determined on the basis of various parameters such as the value of MD and MD, and control is performed so that an operation screen having the determined display content is displayed on the display unit 25. Accordingly, each key described later may be either a hard key or a soft key provided in the operation screen.

  FIG. 3 is an example of the display unit 25 and the key operation unit 26 when the power is turned on.

  In these drawings, the display unit 25 uses, for example, a liquid crystal screen and is used for date / time setting status and date / time information as shown in the lower part of the figure.

  The state shown in FIG. 3 indicates that the operation status of the apparatus is not set by the operator with time information (first type time data), and the time information from an external time information generation source. This is a display screen example corresponding to a case where (second type time data) is not set (when STS = 0), and in such a situation, the CPU 21 displays a display like the display example of FIG. Control is performed so that the operation screen having the contents is displayed on the display unit 25.

  In the key operation unit 26, reference numeral 31 denotes a date / time manual setting key, which is used when manually setting the date / time. In response to the user pressing the key 31, the CPU 21 displays a time information manual setting screen (not shown) on the display unit 25 for setting the date and time (setting the first type of time data) by the user of the apparatus. ) Is displayed. Through the screen and detailed description will be omitted, the numeric keypad 38 for inputting numerical values, the clear key 36 for clearing input, and the enter key 37 for instructing input are used. Date and time information (year, month, day, hour, minute, second, etc.) can be manually set by the operator.

  When manual setting of time information (setting of first type time data) is performed by the operator via the above-described time information manual setting screen (corresponding to step SP4 in the flow of FIG. 2), the CPU 21 sets the STS parameter. The value is updated to “1” (corresponding to step SP5), and the manually set time data is registered in the memory, based on the time measurement process based on the registered time data and the time process result. As shown in FIG. 4 to be described later, the display unit 25 is made to display (that the time information is set for the apparatus and that the time information is manually set by the operator of the apparatus). The operation screen having display data for enabling identification by the user of the apparatus is displayed on the display unit 25) (corresponding to step SP6).

  Thereby, it is possible to make it possible for the user to grasp that the time information is set in the apparatus and that the time information is manually set by the operator via the operation unit.

  Reference numeral 32 denotes a date / time automatic setting key for setting a time interval or the like when forcibly performing date / time setting using the time service server 14 or periodically performing date / time setting using the time service server 14. use. The clear key 36, enter key 37, and numeric keypad 38 are used for setting the time interval and the like.

  Through the key 32 described above, the operator can input an instruction to automatically set time information. When the key 32 is pressed by the user, the CPU 21 receives the instruction, enters the time service use mode, and acquires time information from an external time information generation source such as the time service server 14 capable of data communication with the apparatus. Then, the display unit 25 is caused to execute time measurement processing based on the acquired time information (second type time data) and time display as shown in FIG. The use of this device indicates that time information is set for the time, that the time information is automatically acquired and set from an external time information source, and that the time information has been calibrated. Control so that an operation screen having display data for enabling identification by a person is displayed on the display unit 25). In addition to the series of processes, the CPU 21 controls to update the STS parameter value to “2” (corresponding to the processes in steps SP7 to SP10 in FIG. 2). As a result, time information is set in this apparatus, and the time information is automatically set based on time information from an external time information source, and the time information has already been calibrated. Things can be grasped by the user via the operation unit.

  When the key 32 is pressed, the process shifts to the automatic setting mode, the time information acquisition process from the external time information generation source, the time information setting process acquired from the outside, and the time acquired from the outside The CPU 21 controls to execute the calibration process (time adjustment process) of the time information of the apparatus according to information. These acquisition process, setting process, and calibration process are performed in real time immediately after the user presses the key 32. Or may be controlled to execute after a predetermined time has elapsed since the user pressed the key 32 (for example, one hour later), or the user may press the key 32. It may be controlled to automatically execute every predetermined time (for example, every 4 hours). As described above, the timing for executing the automatic setting process may be appropriately determined in accordance with the use environment of the apparatus, and thus management, operation, and control using time information acquired from an external time information generation source. The present embodiment can be applied to any configuration capable of achieving the above.

  In response to pressing of the key 33, the CPU 21 displays an MD value setting screen (not shown) for enabling parameter MD value setting processing and change processing by the operator. An MD value setting key for inputting an instruction to be displayed on the unit 25, and an upper limit value setting screen for setting an upper limit value of a time interval during which the time service server 14 cannot be used after the time service server 14 is used once. Control is performed so that a detailed setting screen (not shown) having various setting keys such as an upper limit value setting key for inputting an instruction to be displayed on the display unit 25 is displayed on the display unit 25.

  For example, when the MD value setting key (not shown) on the detailed setting screen (not shown) displayed on the display unit 25 in response to the user pressing the key 33 is pressed by the user, the CPU 25 displays the display unit 25. Is switched to the above-described MD value setting screen (not shown), and the value of the parameter MD is controlled to be set and changed by the operator via the screen. The MD value set via this screen is stored as registration information in the memory, and this value is used when the above-described various operation modes are restricted (corresponding to steps SP21 and SP22 in FIG. 7 described later).

  Similarly, a clear key 36, an enter key 37, and a ten key 38 are used for setting an upper limit value. The upper limit value may be a fixed value based on the accuracy of the time measurement function of the apparatus and the guaranteed value of the time accuracy, but in this embodiment, the user can arbitrarily set the initial value from the initial value.

  For example, when the upper limit value setting key (not shown) on the detailed setting screen (not shown) displayed on the display unit 25 in response to the user pressing the key 33 is pressed by the user, the CPU 25 displays the display unit 25. Is controlled to switch to the upper limit setting screen (not shown).

  Via this upper limit setting screen, the user controls to be able to set a time interval for automatically acquiring, setting, and calibrating time information from an external time information generation source such as the time service server 14 under the above-described automatic setting mode. . Thus, for example, when “4 hours” is set as a time interval by the user via the screen, this information is held as management information, and the CPU 21 stores the time service server 14 every time 4 hours elapse. To control the time information to be automatically acquired, set and calibrated.

  Further, in the present embodiment, under the control of the CPU 21, for example, a period in which there is no response from the time service server 14 from the time when an access request is made to the time service server 14 is defined as a no-response period, Is determined to be a calibration error, the value of the STS parameter is set to “3”. For example, as shown in the display example of FIG. Display data to make it possible for the user of this device to identify that it is necessary to adjust the time difference when the time information used is different from the real time information. Is controlled so that it can be displayed on the display unit 25 (corresponding to steps SP13 and SP14 in the flow of FIG. 2).

  In this process, the predetermined period itself used in the process of determining whether or not the non-response period has passed the predetermined period can be set by the user via the above-described upper limit setting screen. .

  For example, when “15 minutes” is set by the user on the upper limit setting screen, the CPU 21 does not receive any response from the time service server 14 even if 15 minutes have elapsed since the time when the time service server 14 was accessed. In response to the determination, the CPU 21 sets the current status related to the time setting of this apparatus to the calibration required state (sets to STS = 3), and notifies that via the display unit 25 as shown in FIG. To notify users.

  Accordingly, the user can also grasp that the time information displayed on the operation unit 25 needs to be calibrated by using the automatic setting mode.

  Reference numeral 34 denotes a start key, which is used to make various settings for the document to be transmitted (image processing settings, destination settings, etc.), and when the user presses the key 34, the CPU 21 receives the key 34 and receives it. To execute the job data transmission operation. A stop key 35 is used as a key for instructing to stop the data transmission and data reception operations.

  Note that the apparatus of this embodiment has a memory that can store a plurality of jobs, such as a hard disk, and can store images in the memory, and printed images can be printed again from the memory. It is configured. Therefore, even when reprinting is performed in this way, the reprint of the received data can be executed by pressing the start key 34 after setting the reprint.

  Based on the configuration of the present embodiment as described above, the description returns to the flowchart of FIG. 2 again. In step SP2, since the apparatus is currently powered on and the parameter STS = 0, the CPU 21 controls the display unit 25 to display “unset” indicating that the date and time are not set. An example of this display is shown in FIG. In this example, “unset” is displayed by characters. In this case, since the date / time information is all 0, the date / time information “0000 00:00:00” may be blinked.

  If the display unit 25 can perform color display, the user may be warned by setting the color or background of the date / time information to, for example, red.

  As described above, according to the present embodiment, as the current operation status of the apparatus, the time information is not set manually or automatically, and the apparatus is operating in a situation where the time information is not set. In this case, the CPU 21 controls to notify the user of information to that effect.

  In the present embodiment, the display unit 25 is employed as an example of the notification unit. However, the form of the notification method is not limited to this, and a notification unit such as a sound unit that outputs sound or a display lamp may be used. For example, a configuration may be used in which information for notifying the user of the above is notified to the user by sound output from the sound unit.

  Next, in step SP3, when the date / time manual setting key 31 of the key operation unit 26 is pressed, when the date / time automatic setting key 32 is pressed, or the time service server 14 set at a predetermined time interval is used. If it is determined whether a periodic service for setting the date and time is necessary and it is determined that none of the conditions is satisfied, the process proceeds to step SP11.

  In the present embodiment, in order to calibrate the date and time information by the time service server 14 (time adjustment processing for adjusting to accurate time, etc.), a predetermined time interval (this time interval is the key 33 as described above). It is assumed that the time service is accessed by the user via the above-described setting screen displayed on the display unit 25 by pressing down, or the time service is accessed by key operation of the key operation unit 26. As described above, in the present embodiment, in response to a key operation from the operation unit as a timing for executing a series of processes including a process of acquiring time data from the time service and a time adjustment process based on the acquired time data. The CPU 21 controls the CPU 21 so that the above processing can be appropriately executed at both timings or at any one timing, when executing in real time at that timing and when executing at predetermined time intervals. doing.

  On the other hand, if it is determined in step SP3 that the date / time manual setting key 31 of the key operation unit 26 is pressed, based on the program executed when it is determined in step SP4 that the date / time manual setting key 31 is pressed. As described above, the date and time are set using the numeric keypad 38 or the like.

  When the date and time are normally input, the process proceeds to step SP5, and the CPU 21 updates the data so that the value of the STS parameter in the memory is the parameter STS = 1.

  Next, the process proceeds to step SP6, and “manual completion” is displayed on the display unit 25 as shown in FIG.

  If the display unit 25 can perform color display, the user may be warned that “the setting has been made but it cannot be guaranteed whether it is really accurate” by setting the color or background of the date / time information to orange, for example. . Then, after step SP6 ends, the process proceeds to step SP11.

  As described above, according to the present embodiment, when the current operation state of the apparatus is a status (setting by the first type time data) in which time information is manually set by the operator via the operation unit. , To that effect (currently, the time information is set for the device, the set time information is manually set by the user via the operation unit, and the time information is manually set by the user) The CPU 21 controls the display unit 25 to display an operation screen including display data for notifying the user that the apparatus is operating under the set conditions.

  On the other hand, when the date / time automatic setting key 32 is pressed in step SP3, or when it is determined that a periodic service for setting the date and time using the time service server 14 set at a predetermined time interval is necessary, the process goes to step SP7. The indicated time service process is executed.

  Specifically, the date and time setting process using the time service server 14 is performed, the process proceeds to step SP8, and it is determined whether or not the date and time setting process in step SP7 has been normally performed. If it is determined in step SP9 that there is an abnormality, the process proceeds to step SP11.

  If it is determined in step SP8 that there is an abnormality, the service of the time service server 14 is stopped, the connection to the Internet 13 cannot be established for some reason, the network card 24 has some trouble, and the time service server 14 There are various factors, such as when you cannot access

  If it is determined that there is an abnormality, it is displayed that there is an abnormality, and if a detailed cause can be specified, it may be displayed on the display unit 25 together.

  When the date and time setting process using the time service server 14 is normally completed in step SP8, the parameter STS = 2 is set in step SP9, and “calibrated” is displayed in step SP10 as shown in FIG. Display. If the display unit 25 can perform color display, the color or background of the date / time information may be set to black or green, for example, so as to clearly indicate to the user that the date / time information can be guaranteed.

  As described above, in the present embodiment, time information acquired from an external time information generation source is set for the present apparatus as the current operation status of the present apparatus (setting by time data of the second type), and the external If the device is operating according to the time information obtained from the above, the fact that the time information is currently set for the device and the set time information is generated by external time information Display the operation screen with display data for notifying the user of the time information acquired from the source and that the device is currently operating according to the time information acquired from the outside. The CPU 21 controls to display on the unit 25.

  On the other hand, in step SP11, the upper limit value of the time interval during which the time service server 14 cannot be used is compared with the current time interval value since the previous time service server 14 was used. In step SP12, it is determined whether the current time is within the predetermined range. If it is determined that the current time is within the range, the process proceeds to step SP3. If it is determined that the current time is out of the range, the process proceeds to step SP13.

  In step SP13, “requires calibration” is displayed on the display unit 25 as shown in FIG. Next, in step SP14, the parameter STS is set to “3” and the process returns to step SP3.

  In step SP13, if the display unit 25 can perform color display, the color or background of the date / time information may be blue, for example, to clearly indicate to the user that the date / time information cannot be guaranteed. .

  As described above, the present embodiment adjusts (calibrates) the time information of the present apparatus using the time information (second type time data) acquired from the external time information generation source as the current operation state of the apparatus. However, if the calibration process has not been properly performed, the fact that the time calibration process based on the time information acquired from the outside is set. The CPU 21 controls the display unit 25 to display an operation screen having display data for notifying the user that the calibration process has not been completed.

  FIG. 7 is a flowchart showing an example of the second data processing procedure in the electronic apparatus according to the present invention, and corresponds to the operation procedure when the various setting keys 33 shown in FIG. 3 are pressed. SP21 to SP24 indicate each step.

  When the various setting keys 33 shown in FIG. 3 are pressed, step SP21 is first executed. In step SP21, it is determined whether or not to set an operation mode such as changing the value of the parameter MD (for example, a detailed setting screen (not shown) displayed on the display unit 25 in response to pressing of the key 33). If it is YES, the process proceeds to step SP22, where an MD value setting screen (not shown) is displayed on the display unit 25, and the MD value setting key (not shown) is pressed by the user. The value of the parameter MD is changed by the user via the screen. Note that the value of the parameter MD is “0” to “2” in the present embodiment, and the step SP22 changes the numerical value within the range of this value. As a result, the CPU 21 controls to update the data of the parameter MD as appropriate.

  In step SP23, it is determined whether it is necessary to change the upper limit of the time interval during which the time service server 14 cannot be used (for example, detailed setting (not shown) displayed on the display unit 25 in response to pressing of the key 33). It is determined whether or not an upper limit value setting key (not shown) on the screen has been pressed by the user). If NO, the process is terminated as it is. If YES, the process proceeds to step SP24, and an upper limit value not shown. The setting screen is displayed on the display unit 25, the upper limit value is changed by the user via the screen, and information on the upper limit value (the process of acquiring time information from the outside and the time using the acquired time information) When a series of calibration processes including an adjustment process are periodically executed every time a predetermined period elapses, setting data indicating how long the predetermined period is set, and time from the time service server 14 In order to acquire information, the time service server 14 is accessed to indicate a time information acquisition request, but when there is no response from the time service server 14, the display unit 25 needs to be calibrated as an error for how long. The setting data relating to the non-response period for determining whether to display the screen is held in the memory, and the process is terminated.

  FIG. 8 is a flowchart showing an example of a third data processing procedure in the electronic apparatus according to the present invention, and corresponds to an Internet facsimile transmission / reception operation procedure based on the parameter MD value. SP31 to SP36 indicate each step. In performing this processing, the CPU 21 reads out the STS parameter value, the MD parameter value, and the information of the management table data 1300 shown in FIG. 13 from the memory, and refers to these information. Control to execute the process.

  This process is executed when the start key 34 shown in FIG. 3 is pressed or when there is a request for automatic reception or manual reception of Internet facsimile.

  First, in step SP31, it is determined whether or not the value of the parameter STS is “2”. If YES, the process proceeds to step SP32 to perform data transmission or data reception operation, and the process is terminated.

  On the other hand, if it is determined in step SP31 that the value of the parameter STS is not “2”, it is determined in step SP33 whether or not the value of the parameter MD is “1”. If YES, the process proceeds to step SP34. The process proceeds to determine whether the request is a reception request. If the request is a reception request, the reception operation is performed. If the request is a transmission request, the process is terminated by skipping nothing.

  On the other hand, if it is determined in step SP33 that the value of the parameter MD is not “1”, it is determined in step SP35 whether the value of the parameter MD is “2”. If YES, the process proceeds to step SP36. The process proceeds to determine whether the request is a transmission request. If the request is a transmission request, the transmission operation is performed. If the request is a reception request, the process is terminated without performing anything.

  On the other hand, if it is determined in step SP35 that the value of the parameter MD is not “2”, this process is terminated.

  Although a detailed operation flow of transmission and reception is omitted, an operation log is left in the HDD 23 at the time of execution. At this time, the STS value is recorded together with the time.

  As described above, according to the flowchart shown in FIG. 8, the limitation of the operation described above is realized by the value of the parameter STS and the value of the parameter MD.

  FIG. 9 is a diagram illustrating a display example of log information related to transmission / reception in the electronic device illustrated in FIG. 1. The log information is controlled by the CPU 21 to be stored and held in a memory (not shown). For example, the log information is appropriately displayed on the display unit 25 in response to an instruction from the user.

  In FIG. 9, a column written as JobID is an ID indicating an operation order when a transmission / reception operation is performed. A column written as “Send / Receive” indicates reception and transmission operations. A column written as STS indicates an STS value when transmission / reception is performed. The column of Date & Time indicates the date, time, minute, and second when transmission / reception is performed.

  In the example of FIG. 9, a transmission operation is performed once when STS = 0 immediately after the power is turned on. It can be seen from the value of the parameter STS that the date and time is manually set before the second transmission, and that the date and time setting using the time service server 14 is performed before JobID = 4.

  The reason why STS = 3 at JobID = 9 is that the upper limit of the time interval during which the time service server 14 cannot be used is set to 96 hours. For some reason, this upper limit is changed from JobID = 8. This indicates that the job ID has been exceeded with JobID = 9.

  Then, before JobID = 10, it can be seen that the time service server 14 can be used normally and has returned to the state of STS = 2.

  The example in FIG. 9 is a data transmission / reception log, and thus records and displays of operations related to time setting are excluded. However, if necessary, a log that has been manually set and automatically calibrated is displayed and printed. Anyway.

  Further, in FIG. 9, only the adopted parameter STS and Date & Time information are recorded, but the parameter STS and Date & Time information of the own device and the partner device before adoption may be recorded and displayed.

  In this case, it is possible to determine an abnormal operation, and it is possible to grasp a more accurate operation situation.

  As described above, in this embodiment, the CPU 21 performs control so as to store and manage the history information of the job processed by this apparatus. As the history information, the job processing mode can be identified for each job. (It is possible to distinguish whether the job is an external transmission mode job or an external reception print mode job), and whether the status of the apparatus when processing the job is STS = 0, STS History data so that it can be distinguished whether the situation is STS = 2, STS = 2, or STS = 3, and the time when the process is executed can be specified. In response to a log information display instruction from the user from the operation unit, the history data is displayed on the display unit 25 in a display screen format like the display example of FIG. Yo are controlled by the CPU21.

  As described above, according to the present embodiment, in the device using the time service server 14, the date and time when the device was operated by recording and using the certainty of the date and time setting information of the device as the value of the parameter STS. Users now know the accuracy of the information.

  In addition, when it is not desired to use the device when the date and time information is inaccurate, the operation can be restricted by an instruction to the user.

  Hereinafter, an example of an operation flow related to information exchange regarding more specific STS information and date / time information will be described with reference to FIGS.

  FIG. 10 is a diagram for explaining a communication session (communication procedure) between the Internet facsimile machine 11 and the Internet facsimile machine 310 shown in FIG.

  FIG. 11 is a flowchart showing an example of a fourth data processing procedure in the electronic apparatus according to the present invention, and corresponds to the transmission processing procedure of steps SP32 and SP36 shown in FIG. In addition, SP41-SP46 show each step.

  First, in step SP41, processing corresponding to the connection shown in FIG. 10 is performed. Then, in step SP42, the processing corresponding to the transmission of the own device time information and the reception of the other device time information shown in FIG. 10 is performed, and the communication delay time is corrected as described above. I do.

  In the present embodiment, the process of step SP43 is added assuming that the counterpart device does not have a built-in time automatic setting function.

  In step SP43, it is determined whether or not the other party has a built-in time automatic setting function. If it is determined that the other party does not have a built-in function, the process proceeds to step SP45. I do.

  In step SP44, the value of the parameter STS of the own device and the value of the parameter STS of the counterpart device are compared, and an optimum time information selection process (for example, the following time information adoption examples 1 to 10) is performed.

[Time information adoption example 1]
For example, when the parameter STS of the own device is 0 (the state is not set) and the parameter STS of the counterpart device is 0, the common parameter STS is “0”, and the mutual information is held as date / time information. Fit.

[Time information adoption example 2]
When the parameter STS of the own device is other than the parameter STS of the partner device, the common parameter STS is the value of the parameter STS of the partner device, and the date and time information of the partner device is adopted as the date and time information.

[Time information adoption example 3]
Further, when the parameter STS of the own device = 1 (manual setting state) and the parameter STS = 0 of the counterpart device, the value of the common parameter STS is “1”, and the date / time information of the own device is used as date / time information. Adopt information.

[Time information adoption example 4]
Further, when the parameter STS of the own device is 1 (manual setting state) and the parameter STS of the counterpart device is 1, the common parameter STS is “1”, and the date and time information includes the date and time information of each device. There is no change.

[Time information adoption example 5]
Further, when the parameter STS of the own device is 1 and the parameter STS of the counterpart device is 2 or 3, the common parameter STS is the value of the STS of the counterpart device, and the date and time information of the counterpart device is adopted as the date and time information. To do.

[Time information adoption example 6]
Further, when the parameter STS of the own device is 2 and the parameter STS of the counterpart device is 2, the common parameter STS is “2”, and the date and time information holds each other's information.

[Time information adoption example 7]
When the parameter STS of the own device is not 2 and the parameter STS = 2 of the counterpart device, the common parameter STS is “2”, and the date and time information of the own device is adopted.

[Time information adoption example 8]
Further, when the parameter STS of the own device is 3 and the parameter STS of the counterpart device is 2, the common parameter STS is “2”, and the date and time information of the counterpart device is adopted.

[Time information adoption example 9]
Further, when the parameter STS of the own device is 3 and the parameter STS of the counterpart device is 3, the common parameter STS is “3”, and the date and time information holds each other's information.

[Time information adoption example 10]
Further, when the parameter STS of the own device is 3 and the parameter STS of the counterpart device is 0 or 1, the common parameter STS is “3”, and the date and time information of the own device is adopted.

  In this example, the determination is made by comparing only the parameter STS values of the own device and the counterpart device, but the comparison of date and time information may be taken into consideration. In that case, abnormality detection is performed when the date and time information is greatly different despite the mutual parameter STS = 2, and the original parameter STS values of the own device and the counterpart device are taken together with the adopted parameter STS value and date and time information. The date information may be recorded so that it can be referred to later.

  In step SP45, when the process in step SP44 is performed, the value of the parameter STS and date / time information of the own apparatus are changed based on the determination.

  Next, in step SP46, Internet fax transmission processing is performed using the corrected parameter STS value and date / time information, and the processing ends.

  FIG. 12 is a flowchart showing an example of a fifth data processing procedure in the electronic apparatus according to the present invention, and corresponds to the reception processing procedure of steps SP32 and SP34 shown in FIG.

  Note that the processing from step SP51 to step SP56 corresponds to step SP41 to step SP46 in FIG.

  The electronic devices include a printer device, a scanner device, a composite image processing device having both a scanner function and a printer function, a portable terminal device (for example, a mobile phone, a digital camera), and the like. An example will be described below.

  In the above-described embodiment, the facsimile apparatus is described as an example of the electronic apparatus. However, the apparatus is another device that performs predetermined data processing with time designation processing, such as a scanner apparatus, a printer apparatus, and a scanner function. The present invention can also be applied to a composite image processing apparatus that performs communication between the printer function and the printer function. The present invention can also be applied to an image processing system in which these devices are connected on a plurality of networks.

[Specific Example 1]
During the process of accessing a homepage on the Internet with a time designation and downloading and printing the latest homepage, the time setting status is judged and access to the homepage is restricted or executed. If the time setting is not accurate even if the printing process is a color page, monochrome printing is performed instead of color printing, and received page information is stored on the hard disk. May be configured as a restriction table so that execution of print processing of the home page can be finely controlled.

[Specific Example 2]
When a plurality of devices can communicate with each other on a network, the use of a composite function or a single function of a composite image processing apparatus that can process on the network may be limited in each time setting state.

[Specific Example 3]
Also, for example, in a composite image processing apparatus, when time-designated print information is added when a print job is received and the time setting is not accurate, monochrome printing is performed instead of a color print request or received. It may be configured to manage the print job processing on the hard disk as a restriction table so that the processing execution of the print job can be finely controlled.

  As described above, according to this embodiment, it is possible to analyze the details of the time setting state in the device using the time service, hold the state, and recognize the user via the operation unit or the like.

  In addition, when reliable date and time information cannot be guaranteed, functional processing that restricts the operation can be easily performed.

  If the operation is not limited, the above time setting state can be recorded simultaneously when the operation state is recorded.

  In addition, processing that can be executed by the device corresponding to the time service function (in this example, an Internet facsimile machine), the above-described various display controls and operation restrictions in consideration of the functions and usage environment can be realized, and appropriate management is performed. It can be operated and the operability can be improved according to the characteristics of the device.

  The control unit 1501 performs overall control of various units (1502 to 1508 and the like) included in the image forming apparatus 1401, and controls each unit to execute appropriate processing.

  Although an example in which the image forming apparatus 1401 includes all these units will be described in this manner, the present embodiment is not limited to this, and a configuration in which some of these units are provided outside (for example, a hard disk) A system in which a storage unit such as 1508 is provided in an external device), a configuration provided in the same casing, or a configuration stored in separate casings (for example, the scanner unit 1502 and the printer unit 1507 are respectively separate casings). The present embodiment can be applied to various apparatus configurations.

  In addition, the control unit 1501 is configured to issue inquiry data to each unit and receive the response result data in order to grasp the operation status of each unit, and grasp the status status of each unit. I can do it.

  For example, based on the status information from the scanner unit 1502, the control unit 1501 confirms information regarding whether or not a document is being read by the scanner 1502 and information on whether or not a document jam has occurred, and the like from the hard disk 1508. Based on the status information, information such as whether the job data is being written or read is checked on the hard disk 1508, and an error occurs whether or not the printer unit 1507 is printing based on the information from the printer unit 1507. Various status information such as confirming whether the external data is being received or being transferred to the external device based on the information from the external communication unit 1505. It is configured so that it can be acquired.

  The image forming apparatus 1401 is configured to be able to use a time service, as in the above example, and can set time information manually from the operation unit of the apparatus (setting of first type time data). At the same time, it is possible to set time information from an external time information generation source (for example, 1402 shown in FIG. 14) capable of data communication with this apparatus (setting of second type time data), and various controls related thereto ( The control unit 1501 executes operation screen display control and operation mode restriction control.

  In response to a user instruction from the operation unit, the control unit 1501 sends time data acquisition request command data to an external device 1402 (also referred to as a time server) serving as an external time information generation source via the network 1400, for example. In response to this, the external device 1402 returns accurate time data to the image forming apparatus 1401, and the image forming apparatus 1401 can appropriately set the aging data acquired from the outside.

  In this embodiment, the control unit 1501 of the image forming apparatus 1401 actively issues a time data acquisition request to the external time information generation source in this way, so that the external time is The time data may be acquired from the information generation source. However, the time data is periodically received from the external apparatus 1402 without outputting the time data acquisition request command from the image forming apparatus 1401 to the external apparatus 1402. The configuration may be such that the control unit 1501 acquires the time data by being distributed.

  However, if at least the operator of the image forming apparatus 1401 inputs that the external time data is desired, for example, as an external time data acquisition request instruction via the user interface such as the operation unit 1503, the external apparatus Time data can be acquired from 1402. The control unit 1501 can execute various display controls for the operation unit 1503 based on the acquired time data from the outside, and operation restriction control of functions and operation modes of the image forming apparatus.

  The control unit 1501 includes a timer unit. For example, when time data is manually set from the operation unit, the timer is counted every second based on the manually set time data. It is reflected as time information (for example, used when displaying the current date and time on the operation unit 1503). Similarly, when the time data from the outside is set, the timer is counted every second based on the time data acquired from the outside, and this is reflected as time information.

  Next, the operation unit 1503 controlled by the control unit 1501 will be described with reference to FIG.

Also, job data output from the scanner unit 1502 and job data output from an external device (1403 to 1406, etc.) are stored and held in a predetermined storage area (also referred to as a box area) inside the hard disk 1508, and the box is stored. There is also a box mode in which desired job data can be selected from the operation unit 1503 after the job data is stored, and can be printed by the printer unit 1507 or transmitted to an external device by the external communication unit 1505 at that time. The As described above, the image forming apparatus according to the present embodiment includes a plurality of operation modes including at least two operation modes. However, the present embodiment is not limited to this, and the image forming apparatus has only one of the operation modes. It may be a functional image forming apparatus.

  The image forming apparatus 1401 is configured to be able to display time information on the display unit 1601 under the control of the control unit 1501, and whether or not the time information is set for the image forming apparatus 1401. If the time information is set, it is time information based on time data (first type time data) manually set by the user via the operation unit 1503 of the user apparatus, or The user can distinguish whether it is time information based on time data (second type time data) supplied from an external time information source (for example, time server 1402 etc.) separately from other states. The control unit 1501 controls the notification data to be notified through the display unit 1601. Note that the display unit 1601 is merely an example of a notification unit, and the present embodiment is not limited thereto. For example, the notification unit 1601 notifies the notification data by a notification unit such as a voice unit capable of outputting sound. Of course, a configuration for notifying the user is also possible. Display control for the operation unit 1503 by the control unit 1501 will be described using an example of an operation screen shown in FIGS.

  The control unit 1501 according to the present embodiment includes user setting information related to time data from the operation unit 1503, registration information related to time data from the memory 1504, and an external time information generation source from the external communication unit 1505 (the time server in FIG. 14). 1402) and the like, as one element of the current status information (current status information) of the image forming apparatus 1401, for example, the following types of status information related to time information are distinguished: It is grasped and managed, and this is reflected on the display screen of the display unit 1601 and used for operation mode restriction.

(1) At present, the image forming apparatus 1401 is not set by the user manually for the time data, and is not set for the automatic acquisition of the time data from the time server, and the time information is not set. (That is, the image forming apparatus 1401 currently uses neither the first type time data nor the second type time data). 1 state (first time information status state).

(2) Currently, the image forming apparatus 1401 has time information already set, and the time information includes time data (first type time data set manually by the user via the operation unit 1503 of the own apparatus). ), And the image forming apparatus 1401 is currently in an operating environment according to the time information (that is, the image forming apparatus 1401 is time information based on the first type time data). The second state (second time information status state) meaning that the user is currently using.

(4) At present, the image forming apparatus 1401 has time information already set, but the time information is time information that is not the most accurate, and calibration processing (current actual time) is performed on the time information. The image forming apparatus 1401 is currently in an operating environment in which the time information needs to be calibrated (that is, the image forming apparatus 1401 is currently using it). The fourth state (fourth time information status state) means that the time information is required to be calibrated such as time adjustment).

  As described above, the image forming apparatus 1401 according to the present embodiment handles a plurality of types of status information related to time information under the control of the control unit 1501.

  When the control unit 1501 determines that the current status (current status) related to time information in the image forming apparatus 1401 corresponds to the first state, the control unit 1501 can identify that the user is in the first state. Display control (for example, an operation screen 1700b having a status display unit 1703b as shown in FIG. 18) on the display unit 1601 is displayed. .

  When it is determined that the current operation state related to the time information in the image forming apparatus 1401 corresponds to the second state, the control unit 1501 enables the user to identify that the second state is the second state. Display control is performed so that a display screen (for example, an operation screen 1700c including a status display unit 1703c as illustrated in FIG. 19) including a status display unit that displays notification data is displayed on the display unit 1601.

  When the control unit 1501 determines that the current status related to the time information in the image forming apparatus 1401 corresponds to the third state, the control unit 1501 notifies the user that the third state can be identified. Display control is performed such that a display screen having a status display unit for displaying data (for example, an operation screen 1700d having a status display unit 1703d as shown in FIG. 20) is displayed on the display unit 1601.

  When the control unit 1501 determines that the status status of the current time information of the image forming apparatus 1401 corresponds to the above-described fourth state, notification data for enabling the user to identify that the state is the fourth state. Display control is performed so that a display screen (for example, an operation screen 1700e including a status display unit 1703e as shown in FIG. 21) is displayed on the display unit 1601.

  In this way, the control unit 1501 gives the user current status information related to time information in the image forming apparatus 1401 among statuses (operational conditions) related to a plurality of types of time information that can occur in the image forming apparatus 1401. The notification data for enabling confirmation is made distinguishable from the status status of other time information, and is generated by the notification unit and controlled to notify the user.

  In addition, as described above, the present embodiment has a plurality of operation modes (a plurality of functions) such as a copy mode and a box mode, and an operation screen corresponding to the selected mode is provided in order to improve operability. The control unit 1501 controls the display unit 1601 to display on the display unit 1601 an operation screen that is easy to understand for each user and is distinguished for each mode.

  In view of this, the present embodiment considers the display screen design that realizes such improved operability, while maintaining the effect of providing an easy-to-use operation screen in an apparatus having such a plurality of operation modes. Status information related to the time information is controlled by the control unit 1501 so that it can be notified to the user, and further operability improvement can be realized in consideration of the user's position, the characteristics of the device, and the usage environment. Below, it demonstrates with the specific example.

  In this embodiment, as described above, a plurality of image forming modes are provided, and a mode selection key group (in FIG. A copy mode key, a send / facsimile key, a box key, and an expansion key), and when one of the mode keys is pressed on the screen, an operation screen corresponding to the selected mode key is displayed. The control unit 1501 controls the display content of the display unit 1601 to be switched. Note that the mode screen to be set as the initial screen can be set in advance by the user via the operation unit 1503 (in this example, the setting mode registration screen is set by the user so that the copy mode setting screen becomes the basic screen). Will be described in the example).

  The control unit 1501 performs display control so as to realize status display control related to the previous time information while maintaining the above-described display control.

  For example, if the current status status regarding the time information of the image forming apparatus 1401 corresponds to the second state, and the copy mode is set in advance as the basic screen, the control unit 1501 displays as shown in FIG. The display unit 1601 causes the display unit 1601 to display the mode selection unit 1701c, the copy mode processing condition setting unit 1702c, and the status display unit 1703c including notification data indicating the second state. 1601 is controlled.

  In this display state, for example, when the transmission / facsimile mode key is pressed by the user in the mode selection unit 1701c on the screen 1700c, the control unit 1501 responds to the mode selection instruction from the user, and transmits / Control is performed to cause the display unit 1601 to display an operation screen corresponding to the facsimile mode, and the status status related to the current time information of the image forming apparatus 1401 corresponds to the second state, and thus indicates the second state. The display unit 1601 is controlled to display the notification data. For example, in this case, as shown in FIG. 22, the control unit 1501 includes a display of the mode selection unit 1701f, a display of the processing condition setting unit 1702f of the transmission / facsimile mode, and notification data indicating the second state. The display unit 1601 is controlled so that the display of the status display unit 1703f is executed together on the display unit 1601.

  Then, the control unit 1501 transmits the user via the operation screen 1700f illustrated in FIG. 22 in a state in which the user understands that the current status state regarding the time state of the image forming apparatus 1401 is the second state. / Various desired processing conditions for job data (image data) to be transmitted under the facsimile mode (destination setting, transmission mode setting, document reading setting, file format setting, stamp setting, job end Various transmission setting parameters such as settings relating to notification) can be set via the processing condition setting unit 1702. When the transmission setting by the user is confirmed and the start key 1604 is pressed, job data transmission processing is executed by the external communication unit 1505 under desired processing conditions from the user.

  Next, another display control example will be described. For example, if the status status regarding the time information of the current image forming apparatus 1401 corresponds to the third state, and the copy mode is set as the basic screen in advance, the control unit 1501 displays, as shown in FIG. The operation unit is configured to cause the display unit 1601 to execute the display of the mode selection unit 1701d, the display of the processing condition setting unit 1702d of the copy mode, and the display of the status display unit 1703d including the notification data indicating the third state. 1503 is controlled.

  In this display state, for example, when the box mode key is pressed by the user in the mode selection unit 1701d on the screen 1700d, the control unit 1501 responds to the mode selection instruction from the user and corresponds to the box mode. In addition to controlling the display unit 1601 to display the operation screen, the status status related to the current time information of the image forming apparatus 1401 corresponds to the third state, so that the notification data indicating the third state is displayed. The display unit 1601 is controlled to execute.

  For example, in this case, as shown in FIG. 23, the control unit 1501 displays the mode selection unit 1701g, the box mode processing condition setting unit 1702g, and the status display including notification data indicating the third state. The display unit 1601 is controlled so that the display of the unit 1703g is executed together on the display unit 1601.

  In the box mode, at least a part of the storage area in the hard disk 1508 included in the image forming apparatus 1401 is set as a box area, the box area is divided into a plurality of boxes in advance, and a box is assigned to each user. In addition, a plurality of job data (a series of image data) can be stored for each box, and job data from the scanner unit 1502 and job data from external devices (1402 to 1406) are stored in the selected box. When the job data stored in the box is output, the user can select a desired box from a plurality of boxes on the operation unit 1503 by the user when outputting the job data stored in the box. Select the desired job data from the list, and apply the processing conditions for the selected job data. The job data selected by the user is read from the box area selected by the user through the output operation in the box mode in the operation unit 1503, and output processing such as external transmission processing or printer processing is performed. Is executed in accordance with the processing conditions set for the job by the user (output processing from the box).

  The control unit 1501 allows the user to grasp that the current status status related to the time status of the image forming apparatus 1401 is the third status via the operation screen 1700g shown in FIG. 23 for the box mode. Various box settings such as various desired processing conditions for the job data (image data) to be output under the box mode (box selection, job selection from the selected box, output processing conditions for the selected job, etc.) Parameter) can be set via the processing condition setting unit 1702.

  In the case of storing job data in a box (reading process to a box) in the box mode, for example, the user selects a desired box from a plurality of boxes (for example, 100 boxes) in the hard disk 1508. The user makes a selection via the box key in the section 1704g (here, it is assumed that the box with box number 1 is selected). In response to this, the control unit 1501 displays on the display unit 1601 a job selection screen 1700h for enabling selection of a job in the selected box as shown in FIG.

  In this example, since the current status related to the time information in the time server 1402 is the third state, the display of the notification data for notifying the user of the third state is maintained in the state where the display is continued. The display unit 1601 is controlled to display the box mode job selection screen 1700h.

  The job selection screen 1700h has a display function for displaying information (job name, paper size, number of pages, storage date, etc.) of a job stored in the box and an operation for selecting a desired job from the box. A list display portion 1709h that also functions is provided.

  In the example shown in FIG. 24, two jobs (two series of image data) have already been stored in this box. These are a job consisting of 12 pages and a job starting from one page. The storage date and time information for specifying when these jobs are stored in this box can be known. In this way, display control is performed so that the job information in the box can be confirmed on the screen. When the document reading key 1707h is pressed by the user, the control unit 1501 starts reading processing, and stores job data from the scanner unit 1502, for example, input according to the instruction, in the box. Control. When the reading process is completed, in this case, the information of the new job data is displayed in a list under the already stored second job.

  When the job output process from the box is executed, a box selection operation is performed via the screen 1700g shown in FIG. 23 as in the previous case (here, the box of box number 1 is the same as the previous one). And the job selection screen 1705h of the selected user box is displayed.

  Then, the user selects a desired job via the list display unit 1709h. In this example, it means that the second job is selected. For example, when the print key 1706h is pressed by the user after the selection of the job, the selected job (document 2) is subjected to the print processing conditions set for the selected job. Accordingly, the control unit 1501 controls the printer unit 1507 to perform printing. On the other hand, when the transmission key 1708h is pressed by the user after the job is selected, this job (document 2) is sent to the external communication unit with the transmission processing conditions set for the selected job. The control unit 1501 controls the external transmission by 1505. As a method for setting the output setting conditions for a job, set the output conditions in advance when reading the job into the box, register it in the box, and select the selected job at the time of output. Via a method to enable output with the output processing conditions set in advance for the selected job, and a setting change screen for changing the output processing conditions for the selected job on a screen (not shown) And a method for enabling new processing conditions to be set.

  As can be seen from the various display transition control examples described above, the control unit 1501 responds to a user operation even when switching from one operation mode to another operation mode (in an image forming mode). Even when the display content of the display unit 1601 is switched from the operation screen to another image formation mode operation screen), the current status information regarding the time information in the image forming apparatus 1401 is grasped in real time when the user wants to know. For example, the status display unit 1703 performs display control such that the status display unit 1703 is always displayed on the display unit 1601, and controls the current status status related to time information so that the user can be notified in real time via the notification unit. (The status status of the current time information on the display unit 1601 described above is under the second state. 19, refer to a display transition control example by the control unit 1501 from the copy mode operation screen 1700c to the transmission / facsimile mode operation screen 1700f shown in Fig. 19. And, the status status of the current time information is in the third state in Fig. 20. FIG. 23 shows a display transition control example by the control unit 1501 from the copy mode operation screen 1700d shown in FIG. 23 to the box mode operation screen 1700g shown in FIG.

  In addition, the control unit 1501 considers that the user performs setting across a plurality of operation screens even under the same operation mode, and from one operation screen to another operation screen under the same image formation mode. Even if the display contents of the display unit 1601 are switched, for example, the status display unit 1703 displays so that the current status information related to the time information in the image forming apparatus 1401 can be grasped in real time when the user wants to know. Display control that is always displayed on the unit 1601 is performed so that the current status situation regarding the time information can be notified to the user via the notification unit in real time (the current unit in the display unit 1601 described above Box selection screen in the box mode shown in FIG. 23 when the status status of the time information is in the third state. Referring display transition control example by the control unit 1501 to the job selection screen 1705h in box mode shown in FIG. 24 from 1700 g).

  In addition, regarding the box mode of this embodiment, authentication data such as a password and an IC card can be set for each box. For example, a box with a password setting and a box without a password setting are controlled to be distinguishable. ing. Then, when accessing a box (when reading or outputting), if the box requires authentication data to be used (for example, a box with a password), the authentication data corresponding to that box Is allowed to be entered via the user's operation to allow processing for that box (job storage in the box or job output from the box), while no authentication data is required to use the box. If the user box is a user box (for example, a user box without a password), control is performed to permit processing (storage of a job in the user box or job output from the user box) for the user box without inputting authentication data by a user operation.

  As described above, according to the present embodiment, the status status regarding the current time information of the device can be displayed to the user separately from other status statuses, and the time service can be supplied. The device itself has a plurality of operation modes, and is designed so that it can be processed by the user via a different operation screen for each mode as a design that considers usability, and the same mode However, the status information can be notified to the user in a notification form that takes into account the features, capabilities, functions, configuration, operability, etc. of the device, such as being configured to be able to be set across multiple operation screens. By making it possible, the operability can be further improved, and even with such a device, the time service can be utilized smoothly and maximally. Also it becomes possible to contribute to the practical application of mounting the multifunction apparatus bis function.

  Regarding the screen display configuration of the present embodiment, the mode selection unit 1701 and the processing condition setting unit 1702 are configured as one display screen, and the status display unit 1703 is configured as one display unit. (Display configuration in a separate screen format). However, the present embodiment is not limited to this, and a display configuration in which these three display components form one operation screen may be used, or each may be a separate display screen. In any case, even when the operation screen is switched from one operation screen to another, for example, when the copy mode setting screen is changed to the facsimile mode setting screen, the notification unit such as the display unit 1601 is used. Any configuration may be used as long as the current status status related to the time information of the image forming apparatus 1401 can be confirmed in real time when the user desires.

  User operations for setting the first type of time data for the image forming apparatus 1401 and user operations for setting the second type of time data will be described with reference to FIGS.

  When the user mode key 1606 on the operation unit 1503 shown in FIG. 16 is pressed by the user, the control unit 1501 displays a user mode setting screen 1800a as shown in FIG. The user can make various common settings via the screen.

  Here, when the timer setting key 1801a on the screen 1800a is pressed by the user, the control unit 1501 responds to this and causes the display unit 1601 to display a timer setting screen 1800b as shown in FIG.

  When displaying the screen 1800b on the display unit 1601, the control unit 1501 displays the date / time setting key 1802b and also displays notification data indicating the current status regarding the time information of the image forming apparatus 1401. (Here, the user is confirmed to be in the first state). When the key 1802b on the screen is pressed, the control unit 1501 causes the display unit 1601 to display a date / time setting screen 1800c having various keys such as keys 1803c to 1805c as shown in FIG. With respect to the time data via the screen, the user selects whether to set the time manually by the user or to automatically set the time data from an external time source.

  When the user selects the key 1803 on the screen 1800c and then presses the OK key 1807c, the control unit 1501 determines that automatic acquisition of time data from the outside is selected by the user, and external time information is generated. Time data is acquired from the source (for example, 1402 in FIG. 14) via the network 1400 (if acquired, the time data from the outside may be displayed on the display unit 1806c), and then the time data is followed. Control is performed so that the image forming apparatus 1401 performs time display, operation control, and the like. When the user presses the key 1804c and then presses the OK key 1807c, the control unit 1501 controls to prohibit the external time data acquisition operation in the image forming apparatus 1401.

  When the key 1805c is pressed by the user, it is determined that the time data has been manually set, the time data is manually set by the user via the display unit 1806c for time setting and the numeric keypad 1605, and the OK key 1807c. After that, the image forming apparatus 1401 is controlled to perform time display, operation control, etc. according to the time data. If any key such as keys 1803c to 1805c is not pressed by the user, it is determined that the time data is not set.

  The control unit 1501 performs control so that setting information from the user on the screen is stored and held in the memory 1504 as initial setting registration information.

  If no key is operated by the user via the screen and it is determined that neither time data of the first type nor the second type is registered, the time in the image forming apparatus 1401 is determined. It is determined that the status state related to the information is the first state. When the time data is manually set by the user via the key 1805c, the control unit 1501 determines that the status state related to the time information in the image forming apparatus 1401 is the second state.

  When automatic acquisition of time data from the outside is selected by the user via the key 1803c, and time data can be appropriately acquired from an external time generation source according to the instruction from the user, and the acquisition If the controller 1501 determines that the image forming apparatus 1401 is operating properly by taking over the acquired time data, the status state related to the time information in the image forming apparatus 1401 is the third state. It is judged that.

  The control unit 1501 is in a situation where the key 1803c is pressed and an automatic acquisition request is made by the user, but time data cannot be properly acquired from an external time source, or time adjustment (calibration) is not possible. Is determined, the status state related to the time information in the image forming apparatus 1401 is determined to be the fourth state.

  The control unit 1501 controls to use these determination results for the above-described display control (operation screen 1700b to screen 1700h in FIG. 17) or for the following operation mode restriction control in the image forming apparatus 1401. Yes.

  The operation mode restriction control by the control unit 1501 in the image forming apparatus 1401 will be described below. As described above, the image forming apparatus 1401 includes a plurality of operation modes (a plurality of functions) including at least one of a copy mode, a transmission / facsimile mode, a printer mode, and a box mode. In each mode, for example, processing condition parameters as a plurality of setting items for one job data (for example, duplex printing is set for job data in copy mode, and a stapling mode is also set. , Nin1 mode is also set).

  In such a configuration, when a job processing request is received according to an instruction from the user and the job data desired by the user is processed, the control unit 1501 determines that the job of interest is the above-described plurality of operation modes (for example, copy Mode, transmission / facsimile mode, printer mode, and box mode), an operation mode determination process is performed to determine which image forming mode the job is. In addition, processing condition determination processing is performed to determine what setting items are included in the processing conditions set for the job data.

  In addition, a time information current status determination process or the like is performed to determine whether the current status status related to time information in the image forming apparatus 1401 is any of the first state to the fourth state. The control unit 1501 defines these determination results obtained by the plurality of determination processes, and rules / rules for limiting the operation mode held as management data in the memory 1504 as shown in FIG. Based on the prohibition data, control is performed so as to determine whether or not the job data can be processed.

  FIG. 28 determines an image forming mode that is allowed to be executed and an image forming mode that is prohibited from being executed for each state from the first state to the fourth state, and is allowed to be executed for each state. The setting item (processing condition parameter) to be executed and the setting item to be executed are determined. The prohibition data as the management data is managed and held in the memory 1504 in a table data format as shown in FIG. 28, for example, and can be referred to by the control unit 1501 together with the above determination result.

  Note that the prohibition data in FIG. 28 is configured to be appropriately modifiable, and can be arbitrarily operated and reconfigured by a user such as an administrator.

  Accordingly, regarding the plurality of operation modes included in the image forming apparatus 1401 of the present embodiment, for example, when the current status state regarding the time information of the image forming apparatus 1401 is the third state, all of the plurality of operation modes are included. In the second state, the execution of the first operation mode and the execution of the second operation mode among the plurality of operation modes are permitted and the execution of the third operation mode is performed. Is prohibited, execution of the first operation mode is permitted in the first state, execution of the second and third operation modes is prohibited, and in the fourth state, the first and second operations are prohibited. The control unit 1501 can perform control so as to prohibit all executions of the third operation mode.

  In addition, for example, even in the same operation mode, control is performed so that execution can be permitted or prohibited depending on processing conditions (setting items) set by the user for job data. As described above, the control unit 1501 is configured to be able to control the control for each state of the first to fourth states.

  This makes it possible to implement fine control in accordance with the characteristics of the image forming apparatus, the capabilities, modes, functions, etc. of the image forming apparatus using the current status information regarding the time information in the image forming apparatus 1401. .

  Hereinafter, an example of a job processing control method by the control unit 1501 according to the prohibition example of FIG. 28 will be described. Note that the following is only an example of the control of the present embodiment, and it is of course possible to apply other than this.

  For example, when the job data to be processed (also called a series of image data) requested to be output by the user is copy mode job data, regardless of the processing conditions (setting items) set in the job data In addition, control is performed so that execution of the job data is permitted even if the current status state regarding the time information in the image forming apparatus 1401 is any of the first to fourth states (table data 1900 in FIG. 28). See copy mode prohibition table).

  For example, when the job data to be processed (also referred to as a series of image data) requested for output by the user is job data in the transmission / facsimile mode, the current status state regarding the time information in the image forming apparatus 1401 is the first. In the case of the 1 state (hereinafter referred to as the first situation), the setting for performing normal facsimile transmission, the setting for performing file transmission, and the box storage are included in the processing conditions set for the job data. When at least one of the setting to be performed and the setting to perform normal reception is included, control is performed to permit execution of processing of the job data.

  In the first situation, the processing conditions of the job data include a setting for performing advanced facsimile transmission, a setting for transmitting e-mail, a setting for performing Internet facsimile transmission, and a setting for performing advanced reception. If at least one of the settings is included, it is not prohibited to decline the processing execution of the job data, but a warning notification is sent to the user such as the display unit 1601 before the processing is executed. And control to execute the process after confirmation by the user.

  In addition, when the job data processing conditions include a setting for performing timer transmission and a setting for performing timer reception under the first situation, the processing execution of the job data is prohibited. (Refer to the prohibition table in the first state of the transmission / facsimile mode of the table data 1900 in FIG. 28).

  The control unit 1501 controls such that such control is performed for each state, for each mode, and for each setting item. Hereinafter, in order to simplify and clarify the description, each state will be described together.

(1) When the control unit 1501 determines that the current status relating to time information in the image forming apparatus 1401 is the first state, for example,
・ Copy mode jobs (all),
A job in a transmission / facsimile mode and set to either normal facsimile transmission setting, storage in a box, direct transmission setting, or normal reception setting,
-Printer mode jobs and single / duplex printing settings, sort mode settings, stapling mode settings, reduced layout mode settings, enlarged layout mode settings, edit mode settings, watermarks A job with any of the settings
・ Settings to store in a passwordless box for a box mode job, or settings to store in a password-protected box, settings to output from a passwordless box, single-sided / double-sided printing setting, sort mode When processing a job such as a job for which any one of the setting and the stapling mode is set, the control unit 1501 controls to allow the processing according to the processing condition set for the job. To do.
In addition, for example, a job in a transmission / facsimile mode, in which any one of a setting for performing advanced facsimile transmission, a setting for transmitting e-mail, a setting for performing Internet facsimile transmission, and a setting for performing advanced reception is made,
A job that is a printer mode job and has been set to perform a hold job (a process that is not printed immediately after being input but is temporarily stored in the hard disk 1508 and printed by the printer unit 1507 only in response to an instruction from the operation unit 1503) ,
When processing a job in a box mode and a job such as a job set to output from a box with a password, the job is executed after a warning notification by the notification unit such as the display unit 1601 is executed. The control unit 1501 controls to allow processing according to the processing conditions set for the user (note that after confirming the warning display, the operation unit 1503 determines whether or not to execute the job processing by the user. For example, in a transmission / facsimile mode job, a setting for performing timer transmission, a setting for notifying job completion, a setting for receiving a timer, or a communication management report A job with any of the settings to perform output,
Setting for performing secure printing as a print mode job (when job data is input, the printer unit 1507 does not print immediately, but holds it in the hard disk 1508, and authentication corresponding to the job via the operation unit 1503) A job for which printing by the printer unit 1507 is performed on the condition that data input is performed by the user,
-Box mode jobs and automatic deletion function (processing that automatically deletes job data from the box on the condition that a predetermined time has elapsed since the job data was stored in the box, and prints job data from the box When processing a job such as a job set to perform a function for automatically deleting the job data from the box on the condition that a predetermined time has elapsed from the time when the job was performed, or job history When performing a display process (a process for displaying history information of a plurality of types of job data stored in the hard disk 1508 on the display unit 1601) or the like, the control unit 1501 controls to prohibit the execution of the process.

(2) When the control unit 1501 determines that the current status regarding the time information in the device 1401 is the second state, for example,
When processing a job in a transmission / facsimile mode and setting to send an e-mail or output a communication management report,
as well as,
When performing job history display, for example, the control unit 1501 is configured to allow the notification unit such as the display unit 1601 to perform warning notification and to perform processing according to the processing conditions set for the job. Control by.
In addition, when processing other than the above case is performed, the control unit 1501 controls to permit the execution of the processing.

(3) When the control unit 1501 determines that the current status regarding the time information in the image forming apparatus 1401 is in the third state, for example, the control unit 1501 performs control so as to permit execution of all the processes described above. .

(4) When the control unit 1501 determines that the current status regarding the time information in the image forming apparatus 1401 is the fourth state, for example,
-Jobs in the transmission / facsimile mode that are set to either normal facsimile transmission, e-mail settings, Internet facsimile transmission settings, box storage settings, or direct transmission settings Processing, and
・ When displaying the job history,
For example, the control unit 1501 controls the control unit 1501 to allow the notification unit such as the display unit 1601 to perform warning notification and to process the job according to the processing conditions set.
Also, for example, a job in a transmission / facsimile mode and a setting to perform progress facsimile transmission, a setting to perform timer transmission, a setting to perform job end notification, a setting to perform progress reception, or a timer reception A job with any setting such as setting or setting to output a communication management report,
A job that is a printer mode job and has either a secure print job setting or a hold job setting,
-Jobs in box mode that are set to output from a password-protected box or set to the automatic deletion function,
Etc., the control unit 1501 controls to prohibit the execution of the processing,
Further, for example, when processing other than the above-described processing is performed, the control unit 1501 controls the execution of the processing.

  The operation mode restriction process according to the prohibition data in FIG. 28 as described above is executed under the control of the control unit 1501.

  As can be seen from the above control example, in the present embodiment, among a plurality of operation modes and processing conditions, operation modes and processing conditions that particularly require time information (timers in the transmission / facsimile mode). With regard to transmission, timer reception, communication management report, automatic deletion function in box mode, etc., control is performed to permit the execution in the second state or the third state (preferably the third state) (the above state) The setting of these modes and processing conditions is prohibited in a state other than the above), and among the plurality of operation modes and processing conditions, those that can be processed without particularly needing time information are the first state and the fourth. Control is possible by the control unit 1501 to permit execution even in the state.

  This makes it possible to use and execute the operation mode and processing using time information with peace of mind in situations where the time information is more accurate (closer to the original accurate time). Can provide a more secure and satisfying device for the user. In addition, for example, in a situation where the accuracy of time information is low, it is possible to restrict the user to use the operation mode and processing using the time information. In reality, it is not accurate (low accuracy). Nevertheless, the actual process is executed when the user uses an operation mode or process that uses time information without noticing it. It is also possible to prevent the occurrence of problems such as the exposure of the user and the inconvenience to the user. In addition, the display control can make the user himself / herself actively notify and confirm the information of the time information, so that the effect can be further enhanced.

  In this embodiment, among the plurality of operation modes and processing conditions, operation modes and processing conditions having higher importance / security levels (secure print setting in the print mode, reading and printing for the password-protected box in the box mode) Etc.), control is made to allow the execution in the second state or the third state (preferably the third state) (in other states, these modes and processing conditions are set) Prohibition) Among the plurality of operation modes and processing conditions, those having a particularly low importance / security level can be controlled by the control unit 1501 that permits execution even in the first state and the fourth state.

  In any case, it is only necessary to create prohibition data as shown in FIG. 28 as appropriate, taking into account the features, capabilities, and the like of the image forming apparatus 1401, and to perform management operations based on the prohibition data.

  Referring to the prohibition table in FIG. 28, for example, when a plurality of processing conditions are set for one job data in a certain operation mode, items that are prohibited from being executed (× in FIG. 19). For job data that includes a combination of items that allow execution (items with a circle in FIG. 28) and items that allow execution but warn (items with a triangle in FIG. 28). , X items may be given top priority, for example, all processing of the job itself may be prohibited, or only processing corresponding to x items may not be executed, and items marked with ○ or Processing corresponding to the item may be performed.

  For example, in the first state, for the job in the box mode, the setting of the output from the passwordless box (corresponding to the item of ○ mark in FIG. 28) and the setting of the automatic deletion function (in FIG. 28, the mark of × mark). If the control unit 1501 executes the process of reading out the job from the box and printing it, the control unit 1501 permits the execution of the process itself but does not automatically delete the job. Alternatively, the printer unit 1507 and the hard disk 1508 may be controlled so that the output of the job is not permitted and automatic deletion is not performed. Regardless of which configuration is adopted, the control unit 1501 controls the corresponding unit so that the execution of the process corresponding to the item marked with x can be prohibited.

  As a method for prohibiting the processing, a processing condition corresponding to the processing is set by the user via the operation unit 1503 or the like, the setting is ignored, and the related unit (for example, the scanner unit 1502) is set. Or the data processing unit 1506, the external communication unit 1505, the printer unit 1507, the hard disk 1508, etc., which directly affects the job data to be processed) by controlling the unit so that the processing is executed. The operation method (for example, touch panel type soft key) for instructing the processing conditions related to the processing or the method to be prohibited is erased from the operation screen, or the operation is performed by shading or graying out in advance. The operation unit is controlled so that the key operation of the key itself cannot be performed by the operator (key operation disabled state). By, there is a method such as to prohibit the execution of the process, can be applied to this embodiment in any way, the present embodiment if configured to actually prohibits the processing should be prohibited is applicable.

  As described above, according to the present embodiment, in conjunction with the above-described display control, the apparatus itself is configured to be able to supply the time service by making the best use of the status status regarding the current time information of the apparatus. Can have a plurality of operation modes, and can control the operation mode of the device while considering their features and usability, and can further improve the operability. Even with such a device, the time service can be utilized smoothly and maximally. For example, it can contribute to the practical use of a multi-function device equipped with a time service function.

  In the above-described embodiment, the display control and the operation mode restriction control by the control unit 1501 on the image forming apparatus 1401 side are mainly described. However, the present embodiment is not limited to this, and for example, the client computers 1403 and 1404 and the like. The same display control and operation mode restriction control as described above can be realized on the external device side such as another digital multifunction peripheral 1405, and the image forming apparatus 1401 can be used from a remote place with the same effect as above. It is configured to be applicable even in cases.

  Hereinafter, as an example of an external apparatus (also referred to as an information processing apparatus), the above-described display control and operation mode restriction control are performed on the client computer 1403 side using a control unit, a printer driver, a status monitor function, and the like included in the client computer 1403. An example of making it executable will be described.

  For example, a client computer 1403 displays a printer driver setting screen for the image forming apparatus 1401 on a display unit of the client computer by a user operation, or a client for knowing the status of the image forming apparatus 1401 When the status monitor function of the computer 1403 is activated, the status request command of the image forming apparatus 1401 is sent from the client computer 1403 to the image forming apparatus 1401 via a communication medium such as the network 1400 in FIG. Send data.

  Upon receiving the command data, the main image forming apparatus 1401 responds to the request and includes the current status information (this status information) in the main image forming apparatus 1401 including the current status data related to the time information of the image forming apparatus 1401. The status information on the operation status such as whether the image forming apparatus is printing, idle or in error, and the remaining amount detection information of the sheet such as the presence / absence of sheets in the paper feed unit and paper discharge unit Status information related to consumables such as running out of toner, no paper, and the like. In addition to the status information related to the time information, such status information is included in the status data to the computer. So that only status information related to time information is sent to the computer It was may be), to reply to the client computer 1403.

  In the client computer 1403, the current status information of the image forming apparatus 1401 acquired from the image forming apparatus 1401 is displayed on the display unit of the computer 1403, for example, in the display examples of FIGS. Control is performed to display notification data such as status display sections 1703b to 1703e.

  Note that the current status information related to the time information of the image forming apparatus 1401 is displayed on the client computer 1403 by, for example, at least the current status information related to the time information of the image forming apparatus 1401 as shown in FIG. A printer driver screen 2000a for the image forming apparatus 1401 having a device status display unit 2001a and a print setting instruction unit for displaying device status information is displayed on the display unit of the client computer 1403 by the control unit of the client computer 1403. Control to display. As another example, for example, a device for displaying status information of a device having at least current status information related to time information of the image forming apparatus 1401 as shown in FIG. The status monitor screen 2000b including the status display unit 2001b may be controlled to be displayed on the display unit of the client computer 1403 by the control unit of the client computer 1403.

  As described above, various display formats are conceivable. At least as the status status regarding the current time information of the image forming apparatus 1401, the image forming apparatus 1401 is currently in the first state to the fourth state. In a notification form that the user can grasp on the client computer 1403 side, which state is different from other states, a notification unit such as a display unit of the client computer 1403 (in addition to the client computer 1403 The notification process may be executed by a notification unit such as a voice output unit included in

  Then, regarding the operation restriction of the job data output from the client computer 1403, the execution is permitted, prohibited, or a warning is displayed according to the prohibited data described for the printer mode in the table data 1900 of FIG. It is sufficient to perform the same control as described above so that it can be selectively executed.

  As a result, the above-described display control and operation restriction control can be executed on the external apparatus side, and the above-described effects according to the present embodiment can be obtained not only on the image forming apparatus side but also on the external apparatus side. The above effects can be provided to the user.

  Regarding the above two types of control (display control, operation restriction control), both of these two controls can be executed on the external device side such as the client computer 1403 using a printer driver, a status monitor, or the like. Alternatively, only one control (for example, only display control) may be executed on the external apparatus side, and the other control (operation restriction control) may be performed by the control unit 1501 of the image forming apparatus 1401. May be configured to be executable.

  The above-described embodiment is not limited to an apparatus such as the image forming apparatus 1401, but is an apparatus that can use time information, such as a printer apparatus, a scanner apparatus, a mobile phone, a digital camera, and preferably a plurality of operation modes and a plurality of processes. The present embodiment (mainly including display control, operation mode restriction control, etc.) can be applied to any apparatus capable of executing the above.

  The configuration of the data processing program that can be read by the electronic apparatus according to the present invention will be described below with reference to the memory map shown in FIG.

  FIG. 31 is a storage medium for storing various data processing programs (including a program for executing the processing of each flowchart and a program for executing display control of each display screen) readable by the electronic apparatus according to the present invention. It is a figure explaining the memory map of.

Icons may also be stored.

  Further, data depending on various programs is also managed in the directory. In addition, a program for installing various programs in the computer, and a program for decompressing when the program to be installed is compressed may be stored.

  The functions shown in FIGS. 2, 7, 8, 11, and 12 and various display control functions in this embodiment may be performed by a host computer by a program installed from the outside. In this case, the present invention is applied even when an information group including a program is supplied to the output device from a storage medium such as a CD-ROM, a flash memory, or an FD, or from an external storage medium via a network. Is.

  As described above, a storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to the system or apparatus, and the computer (or CPU or MPU) of the system or apparatus stores the storage medium in the storage medium. It goes without saying that the object of the present invention can also be achieved by reading and executing the programmed program code.

  In this case, the program code itself read from the storage medium realizes the novel function of the present invention, and the storage medium storing the program code constitutes the present invention.

  As a storage medium for supplying the program code, for example, a flexible disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, a ROM, an EEPROM, or the like is used. it can.

  Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also an OS (operating system) or the like running on the computer based on the instruction of the program code. It goes without saying that a case where the function of the above-described embodiment is realized by performing part or all of the actual processing and the processing is included.

It goes without saying that the case where the CPU or the like provided in the board or the function expansion unit performs part or all of the actual processing and the functions of the above-described embodiments are realized by the processing.

  The present invention is not limited to the above embodiments, and various modifications (including organic combinations of the embodiments) are possible based on the spirit of the present invention, and these are excluded from the scope of the present invention. is not.

  Although various examples and embodiments of the present invention have been shown and described, the spirit and scope of the present invention are not limited to the specific descriptions in the present specification by those skilled in the art.

  As described above, by applying it to an electronic device with a built-in time service, the operator can always know whether or not the date and time currently set is reliable, and when the date and time setting state is a desired state, By enabling operation, it is possible to avoid using the device in an unreliable state.

  Even when the use of the device is not restricted, the date and time setting state in which the device was used is recorded, so that more accurate date and time management is possible.

  Although it can be applied to time setting services using radio waves or telephones, it cannot be corrected when the manually set date is incorrect if it is simply synchronized with time information. There is an inconvenience. In such a case, it is only necessary to change the setting of the apparatus so that a device that cannot be completely guaranteed, such as a manually set date, is assumed to be correct. The present embodiment does not limit the present invention according to the type of time setting service.

  Further, in the device using the time service server 14, the accuracy of the date and time setting information of the device is recorded and used as the value of the parameter STS so that the user can know the accuracy of the date and time information on which the device has operated. became.

  In addition, by exchanging information on the parameter STS with other devices and adopting and recording more reliable information, an operation based on correct date and time information can be performed.

  Furthermore, if the user does not want to use the device when the date / time information is inaccurate, the operation can be restricted by an instruction to the user.

  In addition to these effects, the effects described in the embodiments can be achieved.

  Further, in the above-described embodiment, the operator can identify which of the first state to the fourth state the current status state related to the time information of the device is distinguished from other states. As an example of the notification unit for executing the notification processing of the notification data to be performed, the display unit, the voice unit, the display lamp, and the like have been described. However, the present embodiment is not limited to this. For example, the printer unit 1507 may be configured to print the status information on recording paper. In this case, the printer unit 1507 itself serves as a notification unit. . That is, any notification unit can be applied as long as the user of the apparatus can grasp and check the current status state regarding the time information in the apparatus. Whether the time information to be notified to the user is the time information based on the first type time data or the time information based on the second type time data, as in each of the display screen examples described above. Can be identified by the user that the notification information (information indicating manual completion, information indicating calibration completed), the time information itself is not set, or that calibration is required. The notification information (information indicating non-setting, information indicating calibration required) may be controlled so as to be output so that the user can be notified of this.

  As described above, according to the present embodiment, the time setting in the electronic device capable of measuring the time according to the first time information acquired by the time service or the second time information set by the user is set. The reliability of the current time according to the history is evaluated and displayed on the display unit, and the execution of data processing that can be executed is controlled according to the setting state of the displayed time. The user can confirm the status and easily confirm the accuracy of the display time, and the user can freely determine whether to execute the data processing set by the user according to the setting.

  In addition, according to the present embodiment, the time information acquired when communication is performed between devices having a built-in time setting function that applies a time service is compared with the state of time information that is self-managed. Since the time information is updated and managed based on more reliable time information, whether the current time information is reliable every time the self-managed time information communicates with each other It is possible to objectively determine whether or not to achieve data processing according to time information that is always highly accurate.

  In addition, according to the present embodiment, the status status regarding the current time information of the device can be notified to the user separately from the other status statuses, as well as the time service can be provided.
