  The main display screen 400 monitors and displays the power usage of the device based on the setting in the monitored device display unit 401. When the current check box 402 is selected, the current power consumption can be displayed in real time. Further, when the total check box 403 is selected, individual devices in the past network 102 and the total power consumption of the machine can be confirmed by graph display.

  In addition, the display type selection unit 404 selects one of “1 hour”, “1 day”, “1 week”, “1 month”, “half year”, and “1 year” for the graph display type based on the graph width. Can do. In this figure, “1 day” is selected. Further, the display period designation unit 405 can set the period of the graph to be displayed.

  The electricity rate display unit 406 at the top of the graph displays the total “electricity rate” obtained by converting the amount of power used, and the CO 2 emission amount display unit 407 displays “CO 2 emission amount”. Electricity charges and CO2 emissions can be calculated based on power consumption. In addition, it is possible to select display or non-display of “electricity charge” and “CO2 emission amount” for each device by checking a registered device check box 408 below the graph. The line color of the graph is the color of the line color part 409. In addition, in this figure, “Electricity charge” and “CO2 emission amount” are displayed, but it is also possible to display power consumption and CO2 emission amount charge.

  The display format (graph) switching unit 410 can set the type of graph, for example, a line graph or a bar graph. In addition, the display (graph) switching unit 411 is configured to be able to perform comparison with the same month in the previous year, comparison with the previous month, and comparison with the previous year (see FIG. 4-4).

Moreover, the structure which can perform the input setting of the conversion value (coefficient) or CO2 conversion value (coefficient) which converts an electric power charge by operation from this main display screen 400 may be sufficient (refer FIG. 4-5).

  Next, the various settings described above will be described. For example, the setting is configured such that the user can input by operating a mouse or the like. FIG. 4-2 is a diagram illustrating a screen for selecting addition / deletion of a monitoring target device and power supply state switching in the monitoring target device display unit according to the embodiment of the present invention. The selection screen 420 is displayed when the cursor is moved within the frame of the monitoring target device display unit 401 and the mouse is “right-clicked”. On the selection screen 420, the cursor can be moved to select any one of addition and deletion of monitoring target devices and power supply state switching. For example, when “Add” is selected, a screen for inputting an IP address can be displayed (see FIG. 4-3). When “Delete” is selected, the monitoring target device selected by “Right click” can be deleted. Further, when “switch power state” is selected, the power state of the monitoring target device selected by “right click” can be switched.

The line color setting unit 432 can specify and register the color of the graph display of the monitoring target device. This difference in line color enables discrimination from other devices.

  Further, the interval (polling time) for obtaining device information in the network 102 is registered as 1 minute by default, but this polling time can be changed from the operation unit of the monitoring apparatus. If the interval is short and frequent, the network load increases, and if the interval is long, the data accuracy decreases.

  Note that the power monitoring method of the present embodiment is configured such that monitoring can be performed using a general-purpose MIB (Management Information Base), an A protocol developed exclusively for use, or a B protocol developed exclusively for equipment. A device compatible with a dedicated protocol performs monitoring by checking the protocol check box 433 of the A protocol or the B protocol. The model name is obtained by displaying the model name initially set in the device via the network 102 by registering the IP address.

  When “switch power state” is selected, the power monitoring apparatus 108 remotely shifts the registered monitoring target device to the energy saving operation mode or cancels the energy saving operation mode to enter a standby state. When “switch power state” is selected, when the state of the monitoring target device at the time of selection is the energy saving operation mode, the normal operation mode is selected, and when the state is the normal operation mode, the energy saving operation mode is switched. In the case where the copying operation is being performed, after the copying operation is completed, the energy saving operation mode is entered. For example, the usage method of this function can shift to the energy saving operation mode from the power monitoring apparatus 108 side when the device is not used during a break time or the like. Moreover, since the energy saving operation mode can be confirmed by displaying the power consumption of the device in real time, the energy saving operation mode can also be canceled remotely at the time of going to office or as necessary.

In this conversion value input setting screen 450, the coefficient for calculating the electricity bill and the coefficient for calculating the CO2 emission amount can be set together with the screen update interval, background inversion, and the thickness of the line displayed on the graph. .

  In the present embodiment, the electricity rate is set to 23 yen / kWh based on the power consumption. However, it differs depending on the setting of each electric power company, use at midnight, and the like. Moreover, when calculating an electricity bill and displaying it on the electricity bill display unit 406, a mechanism for adding a basic fee may be provided.

  The CO2 equivalent value is 0.377 kg / kWh for general business operators based on the “FY2003 Greenhouse Gas Emission Calculation Method Study Group” published by the Ministry of the Environment. For example, a coefficient based on resource consumption may be set.

  Next, a format for storing the power consumption calculation result will be described. FIG. 5 is a diagram showing an example of the storage format of the power consumption calculation result according to the embodiment of the present invention. The power consumption calculation result format 500 according to the embodiment of the present invention represents the cumulative power consumption in fiscal 2005.

(Explanation of power monitoring device operation)
Next, the operation of the power monitoring apparatus 108 according to the embodiment of the present invention will be described. FIG. 6A is a flowchart illustrating a processing procedure for acquiring a model name from an IP address. In FIG. 6A, waiting for an IP address to be input (step S611: No), and if an IP address is input (step S611: Yes), the IP address is transmitted to the target image forming apparatus ( Step S612). Next, it is determined whether communication with the image forming apparatus is possible (step S613). As a monitoring protocol at this time, communication is performed by a standard protocol provided in any communication device such as MIB. If communication is not possible (step S613: No), a message that device information cannot be acquired is displayed (step S614). As a result, the series of processes is completed. On the other hand, if communication with the image forming apparatus is possible (step S613: Yes), the model name of the image forming apparatus is acquired (step S615). Then, the model name of the image forming apparatus is displayed (step S616). As a result, the series of processes is completed.

  FIG. 6B is a flowchart of a processing procedure for setting a communication interval (polling time). 6B, first, it is determined whether or not the power consumption accuracy priority display screen has been selected (step S621). If selected (step S621: Yes), the communication interval is set the fastest (step S622). As a result, the series of processes is completed. If no selection is made in step S621 (step S621: No), it is determined whether a network load reduction display screen is selected (step S623). If selected (step S623: Yes), the communication interval is set late (step S624). As a result, the series of processes is completed. In step S623, when not selected (step S623: No), the communication interval is set to the standard (step S625). As a result, the series of processes is completed. Here, in step S623, the case where it is not selected indicates that the display screen is not selected.

  FIG. 6-3 is a flowchart illustrating a processing procedure for setting a conversion value for converting the CO2 emission amount. In FIG. 6C, first, it is determined whether or not a setting input of an electricity bill converted value has been made (step S631). If there is a setting input (step S631: Yes), the power charge currently displayed is recalculated and displayed (step S632). As a result, the series of processes is completed. In step S631, if there is no input setting for the converted electricity bill (step S631: No), it is determined whether there is a setting input for the CO2 converted value (step S633).

  When there is a setting input (step S633: Yes), the currently displayed CO2 emission amount is recalculated and displayed (step S634). As a result, the series of processes is completed. Moreover, when there is no setting input of a CO2 conversion value in step S633 (step S633: No), an electricity bill conversion value and a CO2 emission conversion value are set to a standard value (step S635). As a result, the series of processes is completed. Here, the setting in step S635 may be a case where both the electricity rate conversion value and the CO2 emission conversion value are set to the standard value, or one of them is set to the standard value.

  FIGS. 7A and 7B are flowcharts showing a processing procedure for generating an operation mode corresponding to the A protocol machine. 7A, first, it is determined whether or not communication with the image forming apparatus is possible (step S701). If communication is not possible (step S701: No), a power OFF mode flag is set (step S702). Here, “when communication is not possible” indicates a state in which the main power supply of the image forming apparatus is OFF. “Setting the power OFF mode flag” means that the main power is turned on. Next, all mode flags other than the power OFF mode flag are reset (step S703). This completes a series of processing. In step S701, if communication with the image forming apparatus is possible (step S701: Yes), it is determined whether the power OFF mode flag = 1 (step S704). Here, “power OFF mode flag = 1” means a state in which the power OFF mode flag is set. When the power OFF mode flag is not 1 (step S704: No), the process proceeds to step S708.

  On the other hand, when the power OFF mode flag = 1 (step S704: Yes), the warm-up time timer is started (step S705). Next, a warm-up flag is set (step S706), and the power OFF mode flag is reset (step S707). Then, it is determined whether it is in the standby mode state (step S708). In the case of the standby mode state (step S708: Yes), the copy mode flag is reset because there is a case where the copy mode is shifted to the standby mode (step S709). Next, a standby mode flag is set (step S710). Since there is a possibility of returning from the sleep mode or returning from the warm-up, it is determined whether the returning flag = 1 (step S711). If the returning flag = 1 (step S711: Yes), the return time timer is stopped because the return operation is completed (step S712). Next, the returning flag is reset (step S713), and the return completion flag is set (step S714). As a result, the series of processes is completed.

  In step S711, if the returning flag is not 1 (step S711: No), it is determined whether the warm-up flag is 1 (step S715). If the warm-up flag is not 1 (step S715: No), the series of processes is terminated. On the other hand, when the warm-up flag is 1 (step S715: Yes), the warm-up operation is finished, so the warm-up time timer is stopped (step S716). Next, the warm-up flag is reset (step S717), and the warm-up completion flag is set (step S718). As a result, the series of processes is completed.

  In step S708, if the standby mode state is not set (step S708: No), it is determined whether the standby mode flag = 1 (step S719). If the standby mode flag = 1 (step S719: Yes), the standby mode flag is reset (step S720). As a result, the series of processes is completed. On the other hand, if the standby mode flag is not 1 in step S719 (step S719: No), it is determined whether the copy mode is set (step S721). In the copy mode (step S721: Yes), the standby mode flag is reset (step S722). Next, a copy mode flag is set (step S723). As a result, the series of processes is completed.

  If the copy mode is not set in step S721 (step S721: No), it is determined whether the copy mode flag is 1 (step S724). When the copy mode flag is 1 (step S724: Yes), the copy mode flag is reset (step S725). As a result, the series of processes is completed. In step S724, if the copy mode flag is not 1 (step S724: No), it is determined whether the mode is the sleep mode (step S726). In the sleep mode (step S726: Yes), the standby mode flag is reset (step S727). Next, a flag during sleep mode is set (step S728). As a result, the series of processes is completed.

  In step S726, if the sleep mode is not set (step S726: No), it is determined whether the sleep mode flag = 1 (step S729). When the sleep mode flag is not 1 (step S729: No), the series of processing ends. On the other hand, if the sleep mode flag = 1 (step S729: Yes), the sleep mode has been cancelled, and thus the return time timer is started (step S730). Next, a returning flag is set (step S731), and the sleep mode flag is reset (step S732). As a result, the series of processes is completed.

  FIG. 8A and FIG. 8B are flowcharts showing a processing procedure for generating an operation mode corresponding to the MIB machine. In FIG. 8A, it is determined whether or not communication with the image forming apparatus is possible (step S801). If communication is not possible (step S801: No), a power OFF mode flag is set (step S802). Next, all mode flags other than the power OFF mode flag are reset (step S803). This completes a series of processing. In step S801, if communication with the image forming apparatus is possible (step S801: Yes), it is determined whether the power OFF mode flag = 1 (step S804). When the power OFF mode flag is not 1 (step S804: No), the process proceeds to step S808.

  On the other hand, when the power OFF mode flag = 1 (step S804: Yes), the warm-up time timer is started (step S805). Next, a warm-up flag is set (step S806), and the power OFF mode flag is reset (step S807). Then, it is determined whether there is a copy carry-out number (step S808). Here, the number of copies carried out is confirmed by checking the accumulated number stored in the NV-RAM of the image forming apparatus and by the difference from the previous accumulated number. In addition, for a device in which the recovery time and copy time are short relative to the polling time and the mode time cannot be confirmed, it is also possible to confirm and correct the copy discharge number. If there is a copy carry-out number (step S808: Yes), the standby mode flag is reset (step S809).

  Next, a copy mode flag is set (step S810), and it is determined whether the returning flag = 1 (step S811). If the returning flag = 1 (step S811: Yes), the return time timer is stopped (step S812). Next, the returning flag is reset (step S813), and the return completion flag is set (step S814). As a result, the series of processes is completed. In step S811, if the returning flag is not 1 (step S811: No), it is determined whether the warm-up flag is 1 (step S815). If the warm-up flag is not 1 (step S815: No), the series of processes is terminated.

  On the other hand, when the warm-up flag = 1 (step S815: Yes), the warm-up time timer is stopped (step S816). Next, the warm-up flag is reset (step S817), and the warm-up completion flag is set (step S818). As a result, the series of processes is completed. In step S808, if there is no copy carry-out number (step S808: No), it is determined whether the copy mode flag = 1 (step S819). If the copy mode flag is 1 (step S819: YES), the copy mode flag is reset (step S820). As a result, the series of processes is completed.

  In step S819, if the copy mode flag is not 1 (step S819: No), it is determined whether the warm-up completion flag is 1 (step S821). If the warm-up completion flag = 1 (step S821: Yes), the standby mode flag is set (step S822). Next, the copy mode flag is reset (step S823). As a result, the series of processes is completed. If it is determined in step S821 that the warm-up completion flag is not 1 (step S821: No), it is determined whether the return completion flag is 1 (step S824). When the return completion flag = 1 (step S824: Yes), the standby mode flag is set (step S825).

  Next, the in-copy mode flag is reset (step S826). As a result, the series of processes is completed. In step S824, when the return completion flag is not 1 (step S824: No), it is determined whether the sleep mode is set (step S827). In the sleep mode (step S827: Yes), the standby mode flag is reset (step S828). Next, a flag during sleep mode is set (step S829). As a result, the series of processes is completed.

  In step S827, if the sleep mode is not set (step S827: No), it is determined whether the sleep mode flag = 1 (step S830). When the sleep mode flag is not 1 (step S830: No), the series of processing ends. On the other hand, when the sleep mode flag = 1 (step S830: Yes), the return time timer is started (step S831). Next, the returning flag is set (step S832), and the sleep mode flag is reset (step S833). As a result, the series of processes is completed.

  Next, a processing procedure for measuring the warm-up time and the return time will be described. FIG. 9 is a flowchart showing a processing procedure for measuring the warm-up time and the return time. In the processing procedure shown in FIG. 9, when information on the standby mode is not obtained, the warm-up time and the return time are set in advance, and when the set time is reached, the warm-up operation is completed or the return operation is completed. . In FIG. 9, first, it is determined whether the warm-up flag = 1 (step S901). When the warm-up flag = 1 (step S901: Yes), the warm-up time timer is counted (step S902). Next, it is determined whether the warm-up time timer = N (step S903). Here, in step S903, “Warm-up time timer = N” means whether the value counted by the timer has reached a preset value (N). When the warm-up time timer is not N (step S903: No), the series of processes is terminated.

  On the other hand, if the warm-up time timer = N (step S903: Yes), the warm-up flag is reset (step S904). Next, a warm-up completion flag is set (step S905).

If the returning flag is not 1 (step S906: No), the series of processes is terminated.

  On the other hand, when the returning flag = 1 (step S906: Yes), the return time timer is counted (step S907). Next, it is determined whether the return time timer = N (step S908). If the return time timer is not N (step S908: No), the series of processes is terminated. On the other hand, when the return timer = N (step S908: Yes), the returning flag is reset (step S909). Next, a return completion flag is set (step S910). As a result, the series of processes is completed.

  Next, a processing procedure for calculating power consumption for each operation mode will be described. 10A and 10B are flowcharts illustrating an example of a processing procedure for calculating the power consumption for each operation. In FIG. 10A, first, it is determined whether the power OFF mode flag = 1 (step S1001). If the power OFF mode flag = 1 (step S1001: Yes), it is determined whether the 30-second timer = 1 (step S1002). If the 30-second timer is not 1 (step S1002: No), the series of processes is terminated. On the other hand, if the 30-second timer = 1 (step S1002: Yes), the 30-second timer is reset (step S1003).

  Next, the power consumption for 30 seconds of the OFF time is added to the cumulative power consumption for each minute of the date time (step S1004), and the power consumption for 1 minute of the OFF time is added to the cumulative power consumption for each time of the date. (Step S1005). Then, the power consumption for one minute during the OFF time is added to the cumulative power consumption for each date (step S1006), and the power consumption for one minute during the OFF time is added to the cumulative power consumption for each week of the month (step S1007). Next, the power consumption for one minute during the OFF time is added to the cumulative power consumption for each month (step S1008), and the power consumption for one minute during the OFF time is added to the cumulative power consumption for every six months (step S1009). Then, the power consumption for one minute of the OFF time is added to the cumulative power consumption every year (step S1010). As a result, the series of processes is completed.

  If the power OFF mode flag is not 1 in step S1001 (step S1001: No), it is determined whether the warm-up completion flag is 1 (step S1011). When the warm-up completion flag = 1 (step S1011: Yes), the warm-up time × the 10-second power consumption during the warm-up is calculated (step S1012). Next, the warm-up power consumption is added to the cumulative power consumption per minute of the date time (step S1013), and the warm-up power consumption is added to the cumulative power consumption of the date time (step S1014). Then, the warm-up power consumption is added to the cumulative power consumption for each date (step S1015), and the warm-up power consumption is added to the cumulative power consumption for each week of the month (step S1016).

  Next, the warm-up power consumption is added to the cumulative power consumption for each month (step S1017), and the warm-up power consumption is added to the cumulative power consumption for every six months (step S1018). Then, the warm-up power consumption is added to the accumulated power consumption every year (step S1019), and the warm-up completion flag is reset (step S1020). As a result, the series of processes is completed. In step S1011, when the warm-up completion flag is not 1 (step S1011: No), it is determined whether the return completion flag is 1 (step S1021).

FIGS. 11A to 11C are flowcharts illustrating an example of a processing procedure for controlling the display of the calculated power consumption. In FIG. 11A, first, it is determined whether there is an instruction for current display (step S1101). When there is an instruction for current display (step S1101: Yes), the power consumption for each operation mode for each minute of each device is calculated (step S1102). Next, the calculated power consumption is stored every minute (step S1103), and the stored contents for every minute are displayed (step S1104). As a result, the series of processes is completed.

When there is an instruction to display the bar graph (step S1114: Yes), the daily power consumption of each device is displayed as a bar graph (step S1115). As a result, the series of processes is completed. In step S1114, if there is no instruction for bar graph display (step S1114: No), the power consumption for one hour of each device is displayed for 24 hours (step S1116). Next, the power consumption for one hour of all the target models is displayed for 24 hours (step S1117). As a result, the series of processes is completed.

  In step S1106, when there is no instruction for displaying one day (step S1106: No), it is determined whether there is a display instruction for one month (step S1131). When there is a display instruction for one month (step S1131: Yes), a monthly power consumption charge for each device is calculated (step S1132). Next, the CO2 emission amount is converted from the monthly power consumption of each device (step S1133), and the monthly CO2 emission amount of each device is calculated (step S1134). Then, the monthly CO2 emission fee for each device is calculated (step S1135).

  Next, it is determined whether there is an instruction for a display model (step S1136). If there is no indication of the display model (step S1136: No), the total electricity charge, CO2 emission amount, and CO2 emission charge of the target model are displayed (step S1137), and the process proceeds to step S1139. On the other hand, if there is an instruction for the display model in step S1136 (step S1136: Yes), the electricity rate, CO2 emission amount, and CO2 emission fee of the specified model are displayed (step S1138).

As a result, the series of processes is completed.

  Next, a processing procedure for setting the power consumption (Wh) per minute or hour during standby will be described. FIG. 12-2 is a flowchart illustrating an example of a processing procedure for setting the power consumption (Wh) per minute or one hour during standby. In FIG. 12B, first, it is confirmed whether there is an option connection (step S1221). If there is an option connection (step S1221: Yes), the option connection state of each image forming apparatus is confirmed (step S1222). Next, an optional power consumption for one minute or one hour is calculated (step S1223). Then, the power consumption for one minute or one hour is set according to the standard power consumption and the optional power consumption (step S1224). As a result, the series of processes is completed. In step S1221, if there is no option connection (step S1221: No), the standard power consumption is set for 1 minute or 1 hour (step S1225). As a result, the series of processes is completed.

  Next, a method for setting the power consumption (Wh) per minute or hour in the sleep mode will be described. In the sleep mode, power consumption differs depending on where in the circuit or unit of the device power is supplied. The power consumption in the sleep mode varies depending on the connection state of the network such as USB or TCP / IP. For the power consumption setting in the sleep mode, the network connection state and device information are confirmed in advance, and the power consumption for one minute or one hour in the sleep mode is set.

  Next, a procedure for setting the power consumption per minute or hour in the copy mode will be described. FIG. 12C is a flowchart of the power consumption setting process procedure for one minute or one hour in the copy mode. In FIG. 12C, first, it is determined whether or not information about the recording medium can be acquired (step S1241). When acquisition of information regarding the recording medium is possible (step S1242: Yes), information regarding the recording medium is acquired (step S1242).

  On the other hand, when the information regarding the recording medium can be acquired (step S1241: No), it is determined whether the information regarding the image forming mode can be acquired (step S1243). When acquisition of information regarding the image formation mode is possible (step S1243: Yes), information regarding the image formation mode is acquired (step S1244). Next, the standard power consumption is corrected and the power consumption for 1 minute is set (step S1245). As a result, the series of processes is completed. In step S1243, if it is not possible to acquire information related to the image forming mode (step S1243: No), the power consumption for one minute of the standard power consumption during copying is set (step S1246). As a result, the series of processes is completed.

  Next, the power consumption calculation processing procedure during copying will be described. FIG. 12-4 is a flowchart illustrating an example of a calculation processing procedure during copying. In FIG. 12-4, first, it is determined whether or not information on the number of copies discharged can be acquired (step S1251). If acquisition of information on the number of copies to be ejected is not possible (step S1251: No), a series of processing ends. On the other hand, if the information on the number of copies to be ejected can be acquired (step S1251: Yes), it is determined whether the information on the paper size can be acquired (step S1252).

  If the paper size information can be acquired (step S1252: Yes), the standard power consumption per copy sheet is corrected (step S1253). Here, as an example of correction, correction is performed using 0.36 Wh / sheet (standard) × 1.05. Next, power consumption is calculated by (corrected power consumption of one sheet × number of copies) (step S1254). As a result, the series of processes is completed. If it is not possible to acquire the paper size information in step S1252 (step S1252: No), the power consumption is calculated from (one power consumption × the number of copies) (step S1255). As a result, the series of processes is completed. Note that the above-described processing is effective for a device having a high copy speed or for reducing the network load.

  Next, a procedure for calculating the power during warm-up will be described. FIG. 12-5 is a flowchart illustrating an example of a power calculation process procedure during warm-up. Here, a case where the fixing temperature is detected and the power is calculated will be described as an example. 12-5, first, it is confirmed whether there is a warm-up flag (step S1261). If there is no warm-up flag (step S1261: No), the series of processes is terminated.

  On the other hand, when there is a warm-up flag (step S1261: Yes), information regarding the temperature of the fixing device stored in the NV-RAM of the image forming apparatus 350 is acquired when the main power is turned on or the energy saving mode is canceled (step S1262). . Next, referring to a preset table, the power consumption corresponding to the temperature of the fixing device is converted (step S1263). As a result, the series of processes is completed.

  Next, a procedure for calculating the CO2 emission amount from the consumption amount of consumables will be described. FIG. 13A is a flowchart illustrating an example of a processing procedure for calculating the CO2 emission amount from the consumption amount of consumables. In FIG. 13A, first, it is determined whether information on the number of copies has been acquired (step S1301). If the information on the number of copies has not been acquired (step S1301: No), a series of processing ends. On the other hand, when information on the number of copies is acquired (step S1301: Yes), the number of copies for the acquired time is stored (step S1302). Next, the number of copies for the acquired time is converted into a CO2 emission amount (step S1303). As a result, the series of processes is completed. The number of copies is calculated based on the difference from the acquired time.

  Next, a processing procedure for converting the CO2 emission amount based on the toner discharge amount will be described. FIG. 13B is a flowchart illustrating an example of a processing procedure for converting the CO2 emission amount based on the toner discharge amount. In FIG. 13B, first, it is determined whether toner END information or toner replacement information has been acquired (step S1311). If it has not been acquired (step S1311: No), a series of processing ends. On the other hand, if it is acquired (step S1311: Yes), the number of times of toner END or the number of toner bottle replacements for the acquired time is stored (step S1312). Next, the amount of toner used is calculated from the number of times of toner END or toner bottle replacement during the acquired time (step S1313), and this amount of toner used is converted into a CO2 emission amount (step S1314). As a result, the series of processes is completed.

  Next, a flowchart for automatically setting a communication interval will be described. FIG. 14A is a flowchart illustrating an example of a processing procedure for setting a communication interval (polling time) based on the copy speed. 14A, first, usage information of the image forming apparatus 350 is acquired (step S1411), and it is determined whether the device has a high copy speed (step S1412). In the case of a device with a high copy speed (step S1412: Yes), in the case of a device with a high copy speed, information may not be acquired unless the communication interval is set fast, so the communication interval is set the fastest (step S1413). As a result, the series of processes is completed.

  If it is determined in step S1412 that the copy speed is not high (step S1412: No), it is determined whether the copy speed is medium (step S1414). If the copy speed is medium (step S1414: Yes), the communication interval is set to medium (step S1415). As a result, the series of processes is completed. In step S1414, if the copy speed is not an intermediate device (step S1414: No), the communication interval is set to the slowest (step S1416). As a result, the series of processes is completed.

  FIG. 14B is a flowchart illustrating an example of a processing procedure for setting a communication interval according to a communication state (response). In FIG. 14B, first, the device usage information of the image forming apparatus is acquired (step S1421), and it is determined whether the communication response is fast (step S1422). If the communication response is fast (step S1422: Yes), the network load is light, so the communication interval is set fast (step S1423). And the time zone with an early response is memorize | stored (step S1424). As a result, the series of processes is completed.

  In step S1422, if the communication response is not fast (step S1422: No), it is determined whether the communication response is normal (step S1425). When the communication response is normal (step S1425: Yes), the communication interval is set to the middle (step S1426). Then, the time zone in which the response is middle is stored (step S1427). As a result, the series of processes is completed. If the communication response is not normal in step S1425 (step S1425: No), the communication interval is set late (step S1428). And the time slot | zone with a late response is memorize | stored (step S1429). As a result, the series of processes is completed.

  FIG. 14C is a flowchart illustrating an example of a processing procedure for automatically setting a communication interval according to a holiday or a time zone. 14C, first, it is determined whether or not the current time (when the information related to the date and time is acquired) is a holiday from the information related to the date and time (step S1431). If it is not a holiday (step S1431: YES), it is determined whether the current time is a working time zone (step S1432). In the case of the office time zone (step S1432: Yes), since the network load is heavy during the time zone where employees work, the communication interval is set to be the latest (step S1433). As a result, the series of processes is completed. In step S1431, in the case of a holiday (step S1431: No), the network load is light and the image forming apparatus is rarely used, so the communication interval is set to the middle (step S1434). As a result, the series of processes is completed.

  In step S1432, if it is not the office time zone (step S1432: No), it is determined whether it is currently a break time (step S1435). In the case of a break time (step S1435: Yes), since the image forming apparatus is rarely used, the communication interval is set late (step S1436). As a result, the series of processes is completed. In step S1435, if it is not a break time (step S1435: No), the communication interval is set to the middle (step S1437). As a result, the series of processes is completed.

  Next, processing for changing the communication interval according to the operation mode will be described. FIG. 14-4 is a flowchart illustrating an example of a processing procedure for changing the communication interval according to the operation mode. In FIG. 14-4, it is determined whether the power OFF mode is in effect (step S1441). In the case of the power-off mode (step S1441: Yes), since there is no information to be acquired, the communication interval is set to the latest (step S1442). As a result, the series of processes is completed.

  In step S1441, if it is not in the power-off mode (step S1441: No), it is determined whether it is in the standby mode (step S1443). When in the standby mode (step S1443: Yes), the communication interval is set to the middle (step S1444). As a result, the series of processes is completed. If it is determined in step S1443 that the standby mode is not in effect (step S1443: No), it is determined whether the copy mode is in effect (step S1445). If not in the copy mode (step S1445: No), the series of processing is terminated. On the other hand, when the copy mode is in progress (step S1445: YES), the communication interval is set the fastest (step S1446). As a result, the series of processes is completed.
