Yes. As a derivation of this push scan, there is also known a method called pseudo push scan in which a scanner driver on a PC is started from an image processing apparatus and image data is taken into the PC using the scanner driver (see, for example, Patent Document 1). ).

  When performing push scan or pseudo push scan, it is necessary to designate a PC to which image data is to be sent from the operation unit on the image processing apparatus. That is, in the image processing apparatus, it is necessary to hold information regarding the transmission destination of at least one PC as the transmission destination of the image data.

  Further, in order to improve the convenience for the user, the image processing apparatus needs to detect whether or not the PC is operating and control the instruction so as not to send an image to the PC that is not operating. There is also. As one of methods for realizing such control, a method in which a notification is periodically sent from the PC to the image processing apparatus, and the PC knows the operating status of the image processing apparatus in response to a response from the image processing apparatus. There is.

  In the image processing apparatus, it is possible to know whether or not the PC is in an operating state from the reception state of periodic notifications from each PC. At this time, a method of adding information such as the name of the PC to be displayed on the image processing apparatus and the processing option name of the driver specified when performing the pseudo push scan to the notification periodically sent from the PC to the image processing apparatus Is also known (see, for example, Patent Document 1).

  By the way, image processing apparatuses tend to reduce the capacity of memory to be mounted due to lower prices, and those not equipped with a large-capacity storage device such as a hard disk are also commercially available. In addition, a simple scanning function mounted on an image processing apparatus has been sought.

Specifically, the display position on the display screen 301 shown in FIG. For example, 0x01, 0x02,... In order from the top.

  “Number of menus” in the PC name / menu information sending packet 510 indicates the number of buttons prepared by the scanner driver operating on the client computer. Specifically, a number indicating how many menus are displayed on the display screen 302 shown in FIG. This number is the same value as that set in the pull-down menu 421 shown in FIG.

  The “Menu character string” in the PC name / Menu information sending packet 510 stores a character string to be displayed on the display screen 302 shown in FIG. This character string has the same value as the character string set in the setting fields 423 to 425 shown in FIG.

  In FIG. 7, reference numeral 511 denotes a polling reception event. The polling reception event 511 is transmitted in order to notify the PC name / menu management PC 202 of the reception of the status inquiry packet 501 or the PC name / menu information transmission packet 502 which is periodically transmitted from the client computer to the composite printing apparatus 203. In the illustrated example, the least significant byte is “0x01” in an event of 16 bytes.

  512 is an event that the composite printing apparatus 203 transmits to the PC name / Menu management PC 202 when the user attempts to display a PC name that is not displayed by scrolling up the menu on the display screen 301. It is an example. When the PC names that can be secured by the composite printing apparatus 203 are only enough to be displayed on the operation unit 22 at a time, in order to display the PC names that are not displayed, it is necessary to obtain the data from the PC name / Menu management PC 202. is there. This is an event for notifying the PC name / Menu management PC 202 of the event.

  Reference numeral 513 denotes an event that the composite printing apparatus 203 transmits to the PC name / Menu management PC 202 when the user attempts to display a PC name that is not displayed by scrolling down the menu on the display screen 301. It is an example. When the PC names that can be secured by the composite printing apparatus 203 are only enough to be displayed on the operation unit 22 at a time, in order to display the PC names that are not displayed, it is necessary to obtain the data from the PC name / Menu management PC 202. is there. This is an event for notifying the PC name / Menu management PC 202 of the event.

  Reference numeral 514 denotes an example of an event transmitted from the composite printing apparatus 203 to the PC name / Menu management PC 202 before the composite printing apparatus 203 enters the sleep state. When the PC name / Menu management PC 202 receives this event, the composite printing apparatus 203 enters the sleep state, so that the PC name / Menu management PC 202 does not receive the polling reception Event 511.

  Reference numeral 515 denotes an example of an event transmitted from the composite printing apparatus 203 to the PC name / Menu management PC 202 when the composite printing apparatus 203 that has entered the sleep state returns from the sleep state. When the PC name / Menu management PC 202 receives this event, the PC name / Menu management PC 202 periodically receives the polling reception Event 511 because the composite printing apparatus 203 has returned from the sleep state.

  FIG. 8 is a diagram showing an example of the contents of the PC name / Menu management DB 601 held and managed by the PC name / Menu management PC 202.

  The PC name / Menu management DB 601 includes “IP_Address”, “PC name”, “Number of menus”, “Menu name”, “Update time”, and “Start / end position”. Each row of 602 to 609 shown is information for one client computer.

  “IP_Address” is network address information uniquely held by each client computer. “PC name” is a value set in the PC name setting field 422 shown in FIG. “Number of menus” is a value set in the pull-down menu 421 for the number of buttons shown in FIG. The “Menu name” is a value obtained by grouping the button names input in the setting fields 423 to 425 for the button names 1 to 3 shown in FIG. The “update time” is the time when the PC name / Menu management PC 202 receives the status inquiry packet 501 and the PC name / Menu information sending packet 502 received from the client computer via the composite printing apparatus 203. The value recorded at the “update time” is updated every time the packets 501 and 502 are received.

  The status inquiry packet 501 is sent to the PC name / Menu management PC 202 as response data_polling packet 1_508 via the composite printing apparatus 203. The PC name / Menu information sending packet 502 is sent to the PC name / Menu management PC 202 as response data_polling packet 2_509 via the composite printing apparatus 203.

  The PC name / Menu management PC 202 periodically monitors the “update time”, and if there is data after a certain period of time, it is determined that the client computer has entered a sleep state or turned off. Then, it is deleted from the DB 601. What is deleted from the PC name / Menu management DB 601 is information (PC name, number of menus, etc.) related to the client computer that has entered the sleep state or whose power is turned off.

  The “start / end position” indicates where in the information relating to the client computer stored in the PC name / Menu management DB 601 has been transferred to the composite printing apparatus 203. In the illustrated example, information about client computers from “PC-ABCDE” in which “Start” is stored in “Start / End Position” to “COMPUTER-A” in which “End” is stored is transferred to the composite printing apparatus 203. . As a result, the display screen displayed on the composite printing apparatus 203 is the display screen 301 shown in FIG. When only the information that can be displayed at one time by the composite printing apparatus 203 can be held as in the illustrated example, “PC-ABCDE” storing “Start” is displayed at the top of the display screen 301. . Then, “COMPUTER-A” storing “End” is displayed at the lowest position on the display screen 301.

  When the user wants to display a PC name that is not displayed by scrolling up the menu on the display screen 301, the PC name / Menu information list update request 1 Event 512 from the composite printing apparatus 203 to the PC name / Menu management PC 202. Is sent. As a result, in the PC name / Menu management PC 202, the positions of “Start” and “End” at the start / end positions on the PC name / Menu management DB 601 each move to the next lower position. Then, on the display screen 301 of the operation unit 22 of the composite printing apparatus 203, the entire column in which the PC name is displayed is shifted up by one line. Then, since the lowest line becomes empty, data with “End” newly added thereto is transmitted from the PC name / Menu management PC 202 to the composite printing apparatus 203 and displayed. As a result, the PC name can be displayed as if it was scrolled up one line.

  On the other hand, when the user wants to display a PC name that is not displayed by scrolling down the menu on the display screen 301, the PC name / Menu information list is updated from the composite printing apparatus 203 to the PC name / Menu management PC 202. Request 2 Event 513 is transmitted. As a result, in the PC name / Menu management PC 202, the positions of “Start” and “End” at the start / end positions on the PC name / Menu management DB 601 each move to the position one higher. Then, on the display screen 301 of the operation unit 22 of the composite printing apparatus 203, the entire column in which the PC name is displayed is shifted down by one line. Then, since the top line becomes empty, data with “Start” newly added thereto is transmitted from the PC name / Menu management PC 202 to the composite printing apparatus 203 and displayed. As a result, the PC name can be displayed as if it is scrolled down one line.

  Note that switches or keys for scrolling the menu up and down may be provided on the display screen 301 with a touch panel or the like, or may be provided by other methods.

  FIG. 9 is a flowchart showing scanner driver installation processing executed on the client computer. The processes described below with reference to each drawing are processes executed individually by the client computer, the composite printing apparatus, and the PC name / Menu management PC. The client computer may be any device 204-207. The flow of processing in the entire system will be described with reference to FIG.

  In FIG. 7, in step S <b> 702, the CPU 1 inquires MIB values to various devices (for example, the composite printing apparatus 203) existing on the network 201 and waits for a device that responds with a predetermined MIB value. . Next, in step S703, the CPU 1 determines whether a device responding with a predetermined MIB value determined in advance is found. If the device is found as a result of this determination, it is determined that the device is a device on which the scanner driver can be installed, and the process advances to step S704. On the other hand, if no device is found, it is determined that there is no device on which the scanner driver can be installed, and this processing is terminated.

  In step S704, the CPU 1 inquires about the IP address of the found device, creates a port of the IP address, installs the scanner driver using the port, and ends this processing.

  FIG. 10 is a flowchart showing the scanner driver polling transmission process executed on the client computer. This process is registered in an OS (not shown) at the time of installation, and is automatically executed every time the OS is restarted. Further, it is assumed that the installation process of the scanner driver shown in FIG.

  In FIG. 10, in step S802, the CPU 1 starts a polling interval timer. This is because a polling packet for periodically inquiring the status is sent from the client computer to the composite printing apparatus 203. The interval for sending out this polling packet is T seconds.

  In step S803, the CPU 1 activates a subtask that transmits a polling packet every T seconds. Since the subtask operates independently of other processes, even if the process in FIG. In step S804, the scanner driver operating on the client computer waits for some processing request. FIG. 11 shows a process executed in this process waiting state. Once this process request wait state is entered, the process does not end as it is. If you want to exit, turn off the client computer or uninstall the scanner driver.

  FIG. 11 is a flowchart showing details of the process waiting for a processing request of the scanner driver executed in step S804 of FIG.

  In step S902, the scanner driver waits for a processing request. When any processing request is accepted, it is determined whether the processing request is a pull scan request (step S903). If the request is a pull scan request, the process proceeds to step S907; otherwise, the process proceeds to step S904. The pull scan request is generated when a scanner driver is called from application software running on a client computer.

  In step S904, it is determined whether the request is an OK packet 503 for the status inquiry packet 501 or the PC name / Menu information sending packet 502. If the packet is an OK packet 503, the process proceeds to step S908. Otherwise, the process proceeds to step S905.

  In step S 905, it is determined whether or not the request is a PC name / Menu information request packet 505 for the status inquiry packet 501 or the PC name / Menu information sending packet 502. If it is the PC name / Menu information request packet 505, the process proceeds to step S909. Otherwise, the process proceeds to step S906.

  When the PC name or button name (= Menu name) is changed on the display screen 420 in FIG. 4C, the information must be transmitted to the composite printing apparatus 203. In step S906, such an update is performed. Determine whether it occurred. If an update has occurred, the process proceeds to step S909. If not, the process proceeds to step S910.

  In step S910, it is determined whether or not the request is an event occurrence packet 506 in the sense of performing a pseudo push scan (Push Scan) as a response packet to the status inquiry packet 501 or the PC name / Menu information sending packet 502. If it is the event occurrence packet 506, the process proceeds to step S911. Otherwise, the contents are not to be processed by the scanner driver, and the process returns to step S902 to receive the next request.

  In step S907, the initial screen 401 of FIG. 4A is displayed on the CRT 10 of the client computer, and a normal pull scan is performed. That is, a polling packet (not shown) is issued from the client computer to the composite printing apparatus 203, and pull scan processing is performed. After completion, the process returns to step S902 to receive the next request.

  In step S908, the fact that the OK packet is returned is stored in the RAM 2 in the client computer, and the process returns to step S902 to receive the next request.

  In step S 909, the PC name / Menu information sending packet 502 is sent to the composite printing apparatus 203. After completion, the process returns to step S902 to receive the next request.

  In step S911, a pseudo push scan process is performed as a process for the event occurrence packet for performing the pseudo push scan. The pseudo push scan means that the client computer performs a pull scan in accordance with an instruction from the composite printing apparatus 203.

  The event occurrence packet 506 stores a menu number. This number may be a value that increases by 1 each time the button on the initial screen 401 is moved to the right with the left end being 1, or may be a value that is increased by 1 each time the button is moved to the left with the right end being set to 1. . If the rules are matched between the composite printing apparatus 203 and the scanner driver, there is no problem. The process corresponding to this menu number is automatically started, and the OK button 417 is automatically pressed to perform the scanning process. It should be noted that whether or not the display screen 410 is displayed does not matter in the present invention. In either case, processing is performed so that processing corresponding to the button is activated. After completion, the process returns to step S902 to receive the next request.

  The above is the processing by the scanner driver operating on the client computer.

  FIG. 12 is a flowchart illustrating processing executed by the composite printing apparatus 203 after the power is turned on.

  When the apparatus is turned on, the CPU 12 initializes the memory, initializes the printer engine and the scan engine, and makes the apparatus usable (step S1002). In step S1003, the CPU 12 starts a sleep timer and initializes the variable ST (sets the value to 0). This sleep timer increments the value of the variable ST by 1 every time 1 second elapses.

  In step S1004, the CPU 12 sets the polling packet arrival time monitoring variable N to 60 seconds. The polling packet arrival time monitoring variable N is a variable for deleting the client computer from the PC name / Menu management DB 601 when the composite printing apparatus 203 has not received a polling packet once every N seconds. In the illustrated example, the initial value is 60 seconds. Depending on the sleep state, the value of the variable N changes at the time of return.

  In step S1005, the CPU 12 checks whether the PC name / Menu management PC 202 is in operation. As shown in FIG. 24, it is determined whether the polling transfer request 507 is received within a predetermined time in response to the polling reception event 511 transmitted from the composite printing apparatus 203, as shown in FIG. The monitoring unit or the like executes the reception of the polling transfer request 507. If the result of determination in step S1005 is that it is in operation, processing proceeds to step S1006 and the PC name / menu management PC 202 is operated to manage the PC name and menu information. On the other hand, if it is not in operation, the process advances to step S1007 to process as many PC names / Menu information as can be held on the composite printing apparatus 203.

  In step S1006, the CPU 12 sets “Yes” in the operation FLG (flag) so that the PC name / Menu management PC 202 is in operation.

  In step S1007, the CPU 12 sets “No” in the operation flag so that the PC name / Menu management PC 202 is not operating. Next, in step S1008, the CPU 12 sets “NO” in the interruption flag. This interruption flag is a flag indicating whether or not the composite printing apparatus 203 has entered the sleep state. If “Yes”, it indicates that the composite printing apparatus 203 has entered the sleep state, and if “NO”, it has not entered the sleep state. It shows that.

  In step S1009, the CPU 12 starts polling monitoring Task. Detailed processing of the polling monitoring task will be described with reference to FIG. In step S1010, the CPU 12 waits for an apparatus request. Detailed processing for waiting for a request will be described with reference to FIGS.

  The request waiting process described above continues until the apparatus is turned off.

  FIGS. 13 and 14 are flowcharts showing the request waiting process executed in step S1010 of FIG.

  In step S1102, the CPU 12 receives various requests for the apparatus. In step S1103, the CPU 12 determines whether the request is a copy or fax process using the operation unit 22 of the apparatus. If it is a copy or fax process, the process advances to step S1104. Otherwise, the process proceeds to step S1106.

  In step S1106, the CPU 12 determines whether or not the request is a pseudo push scan process using the operation unit 22 of the apparatus. In the case of pseudo push scan processing, the process proceeds to step S1107. Otherwise, the process proceeds to step S1109.

  In step S1109, the CPU 12 determines whether the request is reception of print data from the client computer or a pull scan request. If it is a print data reception or pull scan request, the process advances to step S1110. Otherwise, the process proceeds to step S1112.

  In step S1112, the CPU 12 determines whether or not the request is polling reception (reception of a status inquiry packet 501 and a PC name / Menu information sending packet 502 from the client computer). If it is polling reception, the process proceeds to step S1113. Otherwise, the process proceeds to step S1119.

  In step S 1119, the CPU 12 determines whether or not the request is a polling packet transfer request 507 from the PC name / Menu management PC 202. If it is a polling packet transfer request 507, the process proceeds to step S1120. Otherwise, the process proceeds to step S1122.

  In step S <b> 1122, the CPU 12 determines whether or not the request is reception of the PC name / Menu information sending packet 510 from the PC name / Menu management PC 202. If the PC name / Menu information sending packet 510 is received, the process advances to step S1123. Otherwise, the process proceeds to step S1125.

  In step S1125, the CPU 12 determines whether or not the request is an instruction to scroll up the menu on the display screen 301 displayed on the operation unit 22 of the apparatus. If so, the process proceeds to step S1126. Otherwise, the process proceeds to step S1125.

  In step S1130, the CPU 12 determines whether or not the request is an instruction to scroll down the menu on the display screen 301 displayed on the operation unit 22 of the apparatus. If so, the process proceeds to step S1131. Otherwise, the process proceeds to step S1135.

  In step S1135, the CPU 12 determines whether or not the request has a relationship of “ST> Sleep setting time” between the variable ST and the sleep setting time. If “ST> Sleep setting time”, the process proceeds to step S1136. Otherwise, the process returns to step S1102. As described in step S1003 of FIG. 12, the value of the variable ST increases by 1 every time 1 second elapses in the sleep timer. The sleep setting time is a variable that sets an interval until the sleep state is entered, and is managed by the composite printing apparatus 203. “ST> Sleep setting time” means that it is time to enter the sleep state because an event that prevents the transition to the sleep state has not occurred during the sleep setting time.

  In step S1104, since the request is a Copy or Fax request using the operation unit 22 of the apparatus, which is an event that hinders the transition to the sleep state, the CPU 12 initializes a variable ST that is a sleep timer ( ST ← 0). Next, in step S1105, processing such as Copy or Fax, which is a requested operation, is performed. Then, the process returns to step S1102 to enter the next request reception process.

  Here, an event that inhibits transition to the sleep state and an event that does not inhibit will be described.

  The obstructing event is an operation using the CPU 12 in the composite printing apparatus 203. On the other hand, an event that does not inhibit is an event that can be handled without using the CPU 12 in the composite printing apparatus 203. The input / output unit 18 of the composite printing apparatus 203 has a proxy response system. If the input packet has a specific pattern, the response packet with the specific pattern can be returned without the help of the CPU 12. . The reception of such a packet is not an event that hinders the transition to the sleep state.

  In step S1107, since the request is a pseudo push scan request using the operation unit 22 of the apparatus, which is an event that hinders the transition to the sleep state, the CPU 12 initializes a variable ST that is a sleep timer. . Next, in step S1108, a pseudo push scan process, which is a requested operation, is performed. Specifically, an event occurrence packet 506 is returned from the client computer as a response packet to the status inquiry packet 501 from the client computer or the PC name / Menu information sending packet 502. Then, the process returns to step S1102 to enter the next request reception process.

  In step S1110, since the request is a print data reception or pull scan request, which is an event that inhibits the transition to the sleep state, the CPU 12 initializes a variable ST that is a sleep timer. Next, in step S1111, print processing or pull scan processing of print data received from the client computer, which is a requested operation, is performed. Then, the process returns to step S1102 to enter the next request reception process. The printing process is a process of interpreting print data sent from a printer driver (not shown) installed on the client computer and printing it by the printing unit 17. In the pull scan process, a scan request is processed by a polling packet (not shown) sent from a scanner driver installed in a client computer. The scan result is returned from the composite printing apparatus 203 to the client computer in a response packet (not shown).

  In step S <b> 1113, the CPU 12 determines whether the request is a status inquiry packet 501. If it is the status inquiry packet 501, the process proceeds to step S1115. If it is the PC name / Menu information sending packet 502, the process proceeds to step S1114. Since receiving the PC name / Menu information sending packet 502 is an event that hinders the transition to the sleep state, in step S1114, the CPU 12 initializes a variable ST that is a sleep timer. In step S1115, an OK packet 503 indicating that the processing on the composite printing apparatus 203 side has been normally completed is returned. Next, in step S1116, the CPU 12 determines the state of the operation flag. If the PC name / Menu management PC 202 is operating and the operation flag is “Yes”, the process advances to step S1117. Otherwise, the process proceeds to step S1118.

  In step S <b> 1117, the CPU 12 transmits a polling reception event 511 indicating that the status inquiry packet 501 or the PC name / menu information sending packet 502 has been received to the PC name / menu management PC 202. Then, the process returns to step S1102 to enter the next request reception process.

  In step S1118, the CPU 12 performs processing in response to reception of the status inquiry packet 501 or the PC name / Menu information sending packet 502 when the PC name / Menu management PC 202 is not operating. If it is a status inquiry packet 501, nothing is done. If it is the PC name / Menu information sending packet 502, the PC name / Menu information DB 601 managed on the RAM 19 of the composite printing apparatus 203 is updated. Since there is an upper limit to the number that can be managed on the RAM 19 of the composite printing apparatus 203, information is added to the DB if the number has not been reached. If the limit is reached, simply ignore it.

  In step S1120, if the request is a polling packet transfer request from the PC name / Menu management PC 202, the CPU 12 initializes a variable ST, which is a sleep timer, because it is an event that hinders the transition to the sleep state. Next, in step S1121, the CPU 12 transfers a polling packet according to the request. If the status inquiry packet 501 has been received before this process, the response data_polling packet 1_508 is transferred to the PC name / Menu management PC 202. On the other hand, if the PC name / Menu information sending packet 502 has been received before this processing, the response data_polling packet 2_509 is transferred to the PC name / Menu management PC 202. Then, the process returns to step S1102 to enter the next request reception process.

  In step S1123, when the request is the PC name / Menu information sending packet 510 from the PC name / Menu management PC 202, the CPU 12 initializes the variable ST, which is a sleep timer, because it is an event that hinders the transition to the sleep state. Turn into. In step S1124, the CPU 12 updates the PC name / Menu information to be displayed on the display screen 301 or 302 stored in the RAM 19 of the composite printing apparatus 203 in accordance with the request.

  In step S1126, since the request is an instruction to scroll up the menu on the display screen 301, which is an event that hinders the transition to the sleep state, the CPU 12 initializes a variable ST that is a sleep timer. Next, in step S1127, the CPU 12 determines the state of the operation flag. If the PC name / Menu management PC 202 is operating and the operation flag is “Yes”, the process proceeds to step S1129. Otherwise, the process proceeds to step S1128.

  In step S1128, since the PC name / menu management PC 202 is not operating, the PC name / menu information to be displayed on the display screen 301 or 302 stored in the RAM 19 of the composite printing apparatus 203 at this time is updated. Then, the process returns to step S1102 to enter the next request reception process.

  In step S 1129, a PC name / Menu information list update request 1 Event 512 is issued to the PC name / Menu management PC 202. Then, the process returns to step S1102 to enter the next request reception process.

  In step S1131, since the request is an instruction to scroll down the menu on the display screen 301, which is an event that hinders the transition to the sleep state, the CPU 12 initializes a variable ST that is a sleep timer. Next, in step S1132, the CPU 12 determines the state of the operation flag. If the PC name / Menu management PC 202 is operating and the operation flag is “Yes”, the process proceeds to step S1134. Otherwise, the process proceeds to step S1133.

  In step S1133, since the PC name / menu management PC 202 is not operating, the PC name / menu information to be displayed on the display screen 301 or 302 stored in the RAM 19 of the composite printing apparatus 203 at this time is updated. Then, the process returns to step S1102 to enter the next request reception process.

  In step S 1134, a PC name / Menu information list update request 2 Event 513 is issued to the PC name / Menu management PC 202. Then, the process returns to step S1102 to enter the next request reception process.

  In step S1136, the CPU 12 determines the state of the operation flag. If the PC name / Menu management PC 202 is operating and the operation flag is “Yes”, the process proceeds to step S1137. Otherwise, the process proceeds to step S1138.

  In step S1137, since the PC name / Menu management PC 202 is in operation, a status monitoring interruption Event 514 is issued to the PC name / Menu management PC 202. Then, the process proceeds to step S1139.

  In step S1138, since the PC name / Menu management PC 202 is not operating, the status monitoring interruption event process shown in FIG. 19 is executed on the RAM 19 of the composite printing apparatus 203. Then, the process proceeds to step S1139.

  In step S1139, the composite printing apparatus 203 is shifted to the sleep state. After steps S1137 and S1138, the composite printing apparatus 203 transitions to the sleep state. Therefore, in both steps S1137 and S1138, processing for transitioning to the sleep state is performed. Processing in the sleep state will be described with reference to FIG. After the sleep state is released, the process returns to step S1102.

  FIG. 15 is a flowchart illustrating processing executed in the sleep state on the composite printing apparatus 203. It is assumed that the composite printing apparatus 203 has transitioned to the sleep state in advance. In this process, since the composite printing apparatus 203 is in the sleep state, the main process is performed by a proxy response system described later.

  In step S1202, the composite printing apparatus 203 is in a sleep state but receives various requests. Even during sleep, it is possible to operate the operation unit 22 of the composite printing apparatus 203 and to receive the status inquiry packet 501 and the PC name / menu information sending packet 502 from the client computer, and the sleep state is canceled depending on the contents. Will be.

  In step S1203, it is determined whether the request is reception of a status inquiry packet 501 or a PC name / Menu information sending packet 502 from the client computer. If the status inquiry packet 501 or the PC name / Menu information sending packet 502 has been received, the process advances to step S1204. Otherwise, the process proceeds to step S1207.

  In step S1204, it is determined whether the packet received from the client computer is a status inquiry packet 501 or not. If it is the status inquiry packet 501, the process proceeds to step S1205. Otherwise, the process proceeds to step S1206.

  In step S1205, an OK packet 503 is returned by the proxy response system. The proxy response system is a simple system that processes received packets during sleep, and is a system that automatically returns a specific response in the case of a specific packet pattern. Since this processing can be performed without using the CPU 12 of the composite printing apparatus 203, the composite printing apparatus 203 can be performed while maintaining a low power consumption state such as a sleep state. After replying by the proxy response system, the process returns to step S1202 again, and a request acceptance process at the next sleep is performed.

  In step S1206, the sleep state is canceled. When the PC name / Menu information sending packet 502 is received, the CPU 12 needs to be used to execute the processing corresponding to the PC name / Menu information sending packet 502. Therefore, the composite printing apparatus 203 is returned from the sleep state to the normal state.

  In step S1207, since the received packet is the PC name / Menu information sending packet 502 and cannot be contained in a specific pattern, an OK packet 503 is returned using the CPU 12 of the composite printing apparatus 203.

  In step S1208, it is determined whether any operation has been performed from the operation unit 22 of the composite printing apparatus 203. If there is an operation, the process proceeds to step S1210. If there is no operation, the process proceeds to step S1209.

  In step S1209, it is determined whether print data has not been received from the client computer. If print data has been received, it is necessary to print it, and the process advances to step S1210. On the other hand, if print data has not been received, nothing is done, so the process returns to step S1202 to perform a request acceptance process at the next sleep.

  In step S1210, the sleep state is canceled. Since any operation or print data received by the operation unit 22 of the composite printing apparatus 203 cannot be handled without using the CPU 12, the composite printing apparatus 203 is returned from the sleep state to the normal state.

  In step S1211, the CPU 12 initializes the sleep timer variable ST because the sleep state has returned to the normal state. In step S1212, it is determined using the operation flag whether the PC name / Menu management PC 202 is operating. If the operation flag is “Yes”, the PC name / Menu management PC 202 is in operation, and the process advances to step S1213. On the other hand, if the operation flag is “No”, the PC name / Menu management PC 202 is not operating, and the process advances to step S1214.

  In step S <b> 1213, since the PC name / Menu management PC 202 is operating, a state monitoring resume Event 515 is issued from the composite printing apparatus 203 to the PC name / Menu management PC 202.

  In step S1214, since the PC name / Menu management PC 202 is not operating, the state monitoring restart event process (FIG. 20 or FIG. 22) operating on the RAM 19 of the composite printing apparatus 203 is performed.

  The above is the processing by the apparatus control system operating on the composite printing apparatus 203.

  FIG. 16 is a flowchart showing a menu management system installation process executed by the PC name / menu management PC 202.

  In step S1302, the menu management system is copied to the external memory 14 in the composite printing apparatus 203. The menu management system is also treated as a kind of driver when viewed from the composite printing apparatus 203, so that it needs to be incorporated into the OS.

  In step S1303, the PC name / menu management PC 202 and the composite printing apparatus 203 are connected by the USB cable 213.

  In step S1304, a P & P occurs between the PC name / menu management PC 202 and the composite printing apparatus 203, and a communication USB port (Port) is created by the OS. The menu management system stored in the external memory 14 in the composite printing apparatus 203 is incorporated into the OS in the PC name / menu management PC 202 using the port.

  FIG. 17 is a flowchart showing processing after starting the menu management system executed by the PC name / menu management PC 202. This process is registered in an OS (not shown) at the time of installation, and is automatically executed every time the OS is restarted.

  In FIG. 17, in step S1402, the CPU 1 sets a polling packet arrival time monitoring variable N to 60 seconds. When N = 60 is set, this means that if no polling reception event is received from the composite printing apparatus 203 for 60 seconds, information regarding the corresponding client computer is deleted from the PC name / Menu information DB 601.

  In step S1403, the CPU 1 sets the interruption flag to “NO”. When the interruption flag is “YES”, it means that the composite printing apparatus 203 has transitioned to the sleep state, and when it is “NO”, it means that the composite printing apparatus 203 is operating without transitioning to the sleep state. .

  In step S1404, the CPU 1 starts polling monitoring Task. Since the polling monitoring task operates independently of other processes, the polling monitoring task remains in operation even after the process of FIG. Next, in step S1405, the CPU 1 waits for a request. A specific operation will be described with reference to FIG.

  FIG. 18 is a flowchart showing a request waiting process of the menu management system executed by the PC name / menu management PC 202.

  In step S1502, the CPU 1 receives various requests for the menu management system. In step S <b> 1503, the CPU 1 determines whether the request is a polling reception event 511 from the composite printing apparatus 203. If it is polling reception Event 511, the process proceeds to step S1507. Otherwise, the process proceeds to step S1504.

  In step S1504, the CPU 1 determines whether the request is a PC name / Menu information list update request 1 Event 512 from the composite printing apparatus 203. If it is the PC name / Menu information list update request 1 Event 512, the process advances to step S1508. Otherwise, the process proceeds to step S1505.

  In step S <b> 1505, it is determined whether the request is a PC name / Menu information list update request 2 Event 513 from the composite printing apparatus 203. If it is PC name / Menu information list update request 2 Event 513, the process advances to step S 1509. Otherwise, the process proceeds to step S1506.

  In step S <b> 1506, it is determined whether the request is a status monitoring interruption Event 514 from the composite printing apparatus 203. If it is the state monitoring interruption Event 514, the process proceeds to step S1510. Otherwise, the process proceeds to step S1511. The composite printing apparatus 203 cannot enter the sleep state if it frequently exchanges the PC name and menu character string with the external management PC 202, but interrupts the monitoring by the management PC 202 during sleep. Accordingly, an external computer can be used without preventing the composite printing apparatus 203 from entering sleep.

  In step S1511, it is determined whether the request is a state monitoring resume Event 515 from the composite printing apparatus 203. If it is the state monitoring restart Event 515, the process proceeds to step S1514. Otherwise, the process proceeds to step S1512.

  In step S1512, it is determined whether the request is response data_polling packet 1_508 which is a response to the polling packet transfer request 507 from the composite printing apparatus 203. If it is response data_polling packet 1_508, the process proceeds to step S1515; otherwise, the process proceeds to step S1513.

  In step S1513, it is determined whether the request is response data_polling packet 2_509, which is a response to the polling packet transfer request 507 from the composite printing apparatus 203. If it is response data_polling packet 2_509, the process proceeds to step S1516. If not, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1507, processing corresponding to the received polling reception Event 511 is performed. This event is issued when the composite printing apparatus 203 receives a status inquiry packet 501 and a PC name / Menu information sending packet 502 from a client computer. This step is an example of the first monitoring unit or the second monitoring unit. Each packet is transferred to the PC name / Menu management PC 202 as it is. Upon receiving this event, the PC name / Menu management PC 202 issues a polling packet transfer request 507 to the composite printing apparatus 203 in the sense of requesting the composite printing apparatus 203 to cross-flow the packet information. Then, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1508, processing corresponding to the received PC name / Menu information list update request 1Event 512 is performed. This event is issued from the composite printing apparatus 203 when an instruction is given to scroll the menu upward on the display screen 301 displayed on the operation unit 22 of the composite printing apparatus 203. When this event is received, the PC name / Menu management PC 202 refers to the PC name / Menu information DB 601 and searches for a place where “Start” and “End” are added to “Start / End Position”. If the total number of data registered in the DB 601 is equal to or less than the number that can be displayed on the display screen 301 at a time, the present process is terminated without doing anything. When the total number of data registered in the DB 601 is more than the number that can be displayed on the display screen 301 at a time, the following processing is performed.

  First, the data with “Start” and “End” are moved to the next lower data, respectively. Next, the data with the new “End” is added to the PC name / Menu information sending packet 510 and transmitted to the composite printing apparatus 203. At this time, on the composite printing apparatus 203 side, the uppermost data in the RAM 19 is erased, and the subsequent data is sequentially moved up one by one, and the standby is performed with the lowermost space left free. The data with “End” added to the received PC name / Menu information sending packet 510 is incorporated at the lowest level in the empty state, and the PC name of the data is displayed on the display screen 301. Thereafter, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1509, processing corresponding to the received PC name / Menu information list update request 2Event 513 is performed. This event is issued from the composite printing apparatus 203 when an instruction is given to scroll the menu downward on the display screen 301 displayed on the operation unit 22 in the composite printing apparatus 203. When this event is received, the PC name / Menu management PC 202 refers to the PC name / Menu information DB 601 and searches for a place where “Start” and “End” are added to “Start / End Position”. If the total number of data registered in the DB 601 is equal to or less than the number that can be displayed on the display screen 301 at a time, the present process is terminated without doing anything. When the total number of data registered in the DB 601 is more than the number that can be displayed on the display screen 301 at a time, the following processing is performed.

  First, the data with “Start” and “End” are moved to the data one level higher. Next, the data with the new “Start” is added to the PC name / Menu information sending packet 510 and transmitted to the composite printing apparatus 203. At this time, on the side of the composite printing apparatus 203, the lowest-order data in the RAM 19 is erased, and the subsequent data is sequentially lowered one by one, and the standby is made with the highest-order empty. The data with “Start” added to the received PC name / Menu information sending packet 510 is incorporated at the highest level in the empty state, and the PC name of the data is displayed on the display screen 301. Thereafter, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1510, state monitoring interruption event processing corresponding to the received state monitoring interruption Event 514 is performed. This event is issued from the composite printing apparatus 203 immediately before the composite printing apparatus 203 enters the sleep state. Details of this processing will be described with reference to FIG. After this processing, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1514, state monitoring restart event processing corresponding to the received state monitoring restart Event 515 is performed. This event is issued from the composite printing apparatus 203 immediately after the composite printing apparatus 203 returns from the sleep state to the normal state. Details of this processing will be described with reference to FIG. 20 or FIG. Both are processing corresponding to the same state monitoring restart Event 515, but the calculation logic of the polling packet arrival time monitoring variable N when returning from the sleep state is different. After step S1514, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1515, response data_polling packet 1 reception processing when response data_polling packet 1_508 is received is performed. When this packet is received, it is first matched with the PC name / Menu information DB 601. The PC name / Menu information DB 601 shown in FIG. 6 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. If there is no matching key as a result of matching with the PC name / Menu information DB 601, the key is newly added. When adding, the information is simply added to the end of the DB 601 and the information of “start / end position” is also updated. Then, the process returns to step S1502 to receive various requests to the menu management system.

  In step S1516, response data_polling packet 2 reception processing when response data_polling packet 2_509 is received is performed. When this packet is received, it is first matched with the PC name / Menu information DB 601. The PC name / Menu information DB 601 shown in FIG. 6 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. If there is no matching key as a result of matching with the PC name / Menu information DB 601, the key is newly added. When adding, the information is simply added to the end of the DB 601 and the information of “start / end position” is also updated. In most cases, an entry has been made in the PC name / Menu information DB 601 based on the processing result of the response data_polling packet 1_508, so that it is only necessary to add the missing Menu information.

  When the menu information is added and the data is completed, the “start / end position” of the PC name / Menu information DB 601 is also updated. As a result of the addition, if it is the amount of data that can be displayed on the display screen 301 at one time, “Start” is set as the highest order data, and “End” is set as the lowest order data. If there is an amount of data that can be displayed on the display screen 301 at one time before the addition, “Start” and “End” are not updated. Then, the process returns to step S1502 to receive various requests to the menu management system.

  FIG. 19 is a flowchart showing details of the state monitoring interruption event process executed in step S1510 of FIG. This processing is executed on the PC if the PC name / Menu management PC 202 is operating, and is executed on the RAM 19 of the composite printing apparatus 203 if the PC name / Menu management PC 202 is not operating. Since the status monitoring is interrupted, the processing is performed when the composite printing apparatus 203 enters the sleep state.

  In step S1602, since the composite printing apparatus 203 enters the sleep state, the interruption flag is set to “Yes”. Next, in step S1603, the time at the time of interruption is secured as interruption time ← current time, and the process ends.

  FIG. 20 is a flowchart showing details of the state monitoring restart event process executed in step S1514 of FIG. 18 or step S1214 of FIG. This processing is executed on the PC if the PC name / Menu management PC 202 is operating, and is executed on the RAM 19 of the composite printing apparatus 203 if the PC name / Menu management PC 202 is not operating. Since the state monitoring is resumed, the processing is performed when the composite printing apparatus 203 returns from the sleep state to the normal state. Note that two processes shown in FIGS. 20 and 22 are prepared for the process corresponding to the state monitoring resume Event 515, and either of them can be used. Which method is used and how it is switched does not matter in the present invention.

  In step S1702, the time at the time of resumption is secured as resumption time ← current time. In step S1703, since the composite printing apparatus 203 returns from the sleep state to the normal state, the interruption flag is set to “No”.

  In step S1704, it is determined whether resumption time−interruption time <10 minutes. This is equivalent to determining whether or not it has been asleep within 10 minutes. If it has been sleeping within 10 minutes, the process proceeds to step S1706, and if not, the process proceeds to step S1705.

  In step S1705, it is determined whether resumption time−interruption time <30 minutes. This is equivalent to determining whether or not it has been asleep within 30 minutes. If it is within 30 minutes that the user has been sleeping, the process proceeds to step S1707. Otherwise, the process proceeds to step S1708.

  In step S1706, the polling packet arrival time monitoring variable N is set to 60 seconds, and this process ends.

  In step S1707, the polling packet arrival time monitoring variable N is set to 30 seconds, and this process ends.

  In step S1708, the polling packet arrival time monitoring variable N is set to 10 seconds, and the process is terminated. The reason for the processing in steps S1706 to S1708 is that if the computer sleeps for a long time, the client computer is likely to enter the sleep state during that time. In such a case, it is determined that it is possible to delete from the display screen 301 by monitoring for a shorter period without monitoring the arrival of the polling packet for 60 seconds. Then, the value of the polling packet arrival time monitoring variable N, which is a monitoring condition, is changed according to the period during which the sleep state has been entered. The above is an example of the first changing unit that changes the monitoring condition of polling according to the time during which the transition to the sleep state has occurred.

  FIG. 21 is a flowchart showing the polling monitoring task process started in step S1009 of FIG. Since this process is a process that does not end once started, no end is arranged in the figure. This process is executed on the PC if the PC name / Menu management PC 202 is operating, and is executed on the RAM 19 of the composite printing apparatus 203 if the PC name / Menu management PC 202 is not operating.

  In step S1802, it is determined whether or not the interruption flag is “NO”. If “YES”, that is, if the composite printing apparatus 203 is not sleeping, the process advances to step S1803. If “NO”, that is, if the composite printing apparatus 203 is in sleep, the process returns to step S1802. For the purpose of preventing the CPU 12 of the composite printing apparatus 203 from being wasted in a useless processing loop, an appropriate wait may be entered before returning to step S1802, and then the process may return to step S1802.

  In step S1803, it is determined whether the polling packet arrival time monitoring variable N is 60 seconds. If it is 60 seconds, the process advances to step S1804. Otherwise, the process proceeds to step S1806. Whether or not the variable N is 60 seconds is determined by checking whether or not the variable N is set to the maximum value because N does not become longer than 60 seconds. In the present embodiment, the default and maximum values of the variable N are set to 60 seconds, but this value is not limited to 60 seconds. Any number of seconds may be used as long as the value is predetermined by the system.

  In step S1804, it is confirmed whether or not the data of update time <current time−N exists in the PC name / Menu information DB 601. In other words, the data whose last update time is N seconds or more before the current time is that the PC name / Menu information DB 601 is not updated for at least N seconds. If there is data corresponding to this condition, the process proceeds to step S1805. If there is no corresponding data, the process returns to step S1802.

  In step S1805, data for which the PC name / Menu information DB 601 has not been updated is deleted from the PC name / Menu information DB 601 for at least N seconds. At this time, if data existing while “Start” and “End” are added to the “start / end position” of the DB 601 is deleted, the information of the DB 601 updated to the composite printing apparatus 203 is stored as the PC name / Menu. The information is sent by an information sending packet 510. If the outside between “Start” and “End” is deleted in the “start / end position” of the PC name / Menu information DB 601, only the PC name / Menu information DB 601 is updated. Thereafter, the process returns to step S1802.

  In step S1806, it is determined whether current time <restart time + N. If the current time is smaller than the restart time + N, it is a time zone in which the update status of the PC name / Menu information DB 601 may not be monitored yet. In such a case, the process returns to step S1802. Otherwise, the process proceeds to step S1807.

  In step S1807, it is determined whether there is data of update time <restart time. It is clear that the current time is greater than the resume time + N when the process comes here. If the update time is smaller than the restart time in this state, the process proceeds to step S1808 because it is a deletion target. Otherwise, the process proceeds to step S1809.

  In step S1808, the corresponding data is deleted from the PC name / Menu information DB 601. At this time, if data existing while “Start” and “End” are added to the “start / end position” of the DB 601 is deleted, the information of the DB 601 updated to the composite printing apparatus 203 is stored as the PC name / Menu. The information is sent by an information sending packet 510. If the outside between “Start” and “End” is deleted in the “start / end position” of the PC name / Menu information DB 601, only the PC name / Menu information DB 601 is updated. Thereafter, the process proceeds to step S1809. In this way, even when an external computer is not operating, it is possible to hold and use as much information as can be secured in the composite printing apparatus 203.

  In step S1809, the smaller one of 60 seconds and the current time-restart time is substituted into the variable N. Since N is a value that sequentially advances from the restart time with 60 seconds as the maximum, the calculation is performed. Thereafter, the process returns to step S1802.

  FIG. 22 is a flowchart showing details of the state monitoring restart event process executed in step S1514 of FIG. 18 or step S1214 of FIG. This processing is executed on the PC if the PC name / Menu management PC 202 is operating, and is executed on the RAM 19 of the composite printing apparatus 203 if the PC name / Menu management PC 202 is not operating.

  In step S1902, the time at the time of resumption is secured as resumption time ← current time. In step S1903, the composite printing apparatus 203 returns from the sleep state to the normal state, so the interruption flag is set to “No”.

  In step S1904, using the Matrix A 1910 shown in FIG. 23, the value of the polling packet arrival time monitoring variable N is set using the sleep interruption time and the resume time from the sleep state. For example, when the sleep interruption time is 8:00, when the resume time from the sleep state is up to 19:00, the polling packet arrival time monitoring variable N is set to 60 seconds, and after returning after that, 10 seconds. And When the sleep interruption time is 17:00, when the resume time from the sleep state is after 5 o'clock the next day, the polling packet arrival time monitoring variable N when returning from the sleep state is 10 seconds. To do. This is because the former can be judged that the client computer is often in operation during general business hours, so the polling packet arrival time monitoring variable N when returning from the sleep state is set to 60 and can be easily deleted from the DB 601. This is a result of consideration not to be done.

  In the case of the latter, it is a case where it went into the sleep state from the evening to the next morning. In this case, since it can be determined that the client computer is not operating at all, the polling packet arrival time monitoring variable N when returning from the sleep state is set to 10 and is easily deleted from the PC name / Menu information DB 601. Consider. The above is an example of the second changing unit that changes the monitoring condition of polling according to the time when the sleep state is changed and the time when the state returns. Matrix A 1910 is not limited to the illustrated example.

  The above is the processing in the menu management system operating on the PC name / menu management PC 202 (part of the processing is executed on the composite printing apparatus 203 or the PC name / menu management PC 202).

  Next, the relevance and flow of processing executed on the above-described client computer, composite printing apparatus 203, and PC name / menu management PC 202 will be described.

  FIG. 24 is a diagram for explaining a flow of a series of processing until a display screen 301 is displayed on the operation unit 22 of the composite printing apparatus 203 after a new scanner driver is installed in the client computer. The PC name / Menu management PC 202 is assumed to be operating as a premise.

  In S2001, the scanner driver is installed on the client computer. At this time, it is assumed that the IP address of the client computer is “111.222.333.444”. In step S2002, when the installation of the scanner driver is completed, a status inquiry packet 501 is issued from the client computer to the composite printing apparatus 203.

  In step S2003, the composite printing apparatus 203 returns an OK packet 503 to the client computer. At the same time, polling reception Event 511 is issued to PC name / Menu management PC 202.

  In step S <b> 2004, the PC name / Menu management PC 202 issues a polling packet transfer request 507 to the composite printing apparatus 203.

  In step S2005, the composite printing apparatus 203 issues response data_polling packet 1_508 to the PC name / Menu management PC 202. When receiving the response data_polling packet 1_508, the PC name / Menu management PC 202 first matches the PC name / Menu information DB 601. The PC name / Menu information DB 601 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. If there is no matching key as a result of matching with the PC name / Menu information DB 601, the key is newly added. When adding, the information is simply added to the end of the DB 601 and the information of “start / end position” is also updated.

  In S2006, a PC name / Menu information sending packet 502 is issued from the client computer to the composite printing apparatus 203. The composite printing apparatus 203 acquires information about the client computer (PC name, number of menus, menu character string) from the received PC name / menu information sending packet 502. After installing the scanner driver, the scanner driver is set in advance so that the PC name / Menu information sending packet 502 is skipped in the next packet after skipping the status inquiry packet 501.

  In step S2007, the composite printing apparatus 203 returns an OK packet 503 to the client computer. At the same time, polling reception Event 511 is issued to PC name / Menu management PC 202. In step S <b> 2008, the PC name / Menu management PC 202 issues a polling packet transfer request 507 to the composite printing apparatus 203.

  In step S2009, the composite printing apparatus 203 issues a response data_polling packet 2_509 to the PC name / Menu management PC 202. When receiving the response data_polling packet 2_509, the PC name / Menu management PC 202 matches the PC name / Menu information DB 601. The PC name / Menu information DB 601 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. If there is no matching key as a result of matching with the PC name / Menu information DB 601, the key is newly added. When adding, the information is simply added to the end of the DB 601 and the information of “start / end position” is also updated. In most cases, the entry is completed in the PC name / Menu information DB 601 based on the processing result of the response data_polling packet 1_508, and therefore, the processing is only to add the missing Menu information. When the processing so far is completed, information relating to one client computer is completed on the PC name / Menu information DB 601.

  In step S2010, when information on one client computer is completed on the PC name / Menu information DB 601, the information is sent from the PC name / Menu management PC 202 to the composite printing apparatus 203 as a PC name / Menu information sending packet 510. To do. In step S2011, information on the scanner driver newly installed in the client computer for the first time at this time can be displayed on the composite printing apparatus 203.

  In step S2012, a status inquiry packet 501 is issued from the client computer to the composite printing apparatus 203. This is a packet meaning normal status inquiry.

  In step S2013, the composite printing apparatus 203 returns an OK packet 503 to the client computer. At the same time, polling reception Event 511 is issued to PC name / Menu management PC 202.

  In S2014, the PC name / Menu management PC 202 issues a polling packet transfer request 507 to the composite printing apparatus 203.

  In step S2015, the composite printing apparatus 203 issues a response data_polling packet 1_508 to the PC name / Menu management PC 202. When receiving the response data_polling packet 1_508, the PC name / Menu management PC 202 matches the PC name / Menu information DB 601. The PC name / Menu information DB 601 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. As a result of matching with the PC name / Menu information DB 601, there is a matching key, so the “update time” of the key is updated to the current time held in the PC name / Menu management PC 202. Thereafter, in particular, if there is nothing, S2012 to S2015 are repeated every polling interval T seconds.

  In this way, information about the client computer is transmitted to the PC name / Menu management PC 202 via the composite printing apparatus 203, and the information is managed by the PC name / Menu management PC 202, and finally displayed on the composite printing apparatus 203. Will come to be.

  FIG. 25A is a diagram for explaining a processing flow when the menu is scrolled up on the display screen 301 displayed on the operation unit 22 on the composite printing apparatus 203. FIG. 25B is a diagram for explaining the flow of processing when the menu is scrolled down on the display screen 301.

  In FIG. 25A, in S2101, an instruction to scroll up the menu on the display screen 301 of the operation unit 22 is accepted. In step S <b> 2102, the composite printing apparatus 203 issues a PC name / menu information list update request 1 Event 512 to the PC name / menu management PC 202. Receiving it, the PC name / Menu management PC 202 extracts information on the requested transmission destination from the PC name / Menu information DB 601.

  In step S <b> 2103, information about the transmission destination extracted from the PC name / Menu information DB 601 is sent from the PC name / Menu management PC 202 to the composite printing apparatus 203 by a PC name / Menu information sending packet 510. In S2104, the PC name and Menu information to be displayed when scrolled up are displayed on the display screen 301.

  In FIG. 25B, in S2111, an instruction to scroll down the menu on the display screen 301 of the operation unit 22 is accepted. In step S <b> 2112, the composite printing apparatus 203 issues a PC name / menu information list update request 1 Event 512 to the PC name / menu management PC 202. Receiving it, the PC name / Menu management PC 202 extracts information on the requested transmission destination from the PC name / Menu information DB 601.

  In step S <b> 2113, information related to the transmission destination extracted from the PC name / Menu information DB 601 is sent from the PC name / Menu management PC 202 to the composite printing apparatus 203 using a PC name / Menu information sending packet 510. In S2114, the PC name and Menu information to be displayed when scrolled down are displayed on the display screen 301.

  FIG. 26 is a diagram for explaining the flow of processing when the polling reception Event 511 does not reach the PC name / Menu management PC 202 due to the power-off of the client computer or the like. In the following example, description will be made on the assumption that polling from the client computer with the IP address: 111.222.333.444 has stopped.

  In S2201, the PC name / Menu management PC 202 detects that polling from a client computer having an IP address of “111.222.333.444” does not come. This is because the polling reception Event 511 is picked up as a client computer that has not been received by monitoring the update status of the PC name / Menu information DB 601 using the polling monitoring task shown in FIG.

  In step S2202, information on the client computer having the IP address “111.222.333.444” is deleted from the PC name / Menu information DB 601. In step S2203, data to be transferred from the PC name / menu management PC 202 to the composite printing apparatus 203 is grasped. When data existing between “Start” and “End” in the “start / end position” of the DB 601 is deleted, the operation of the composite printing apparatus 203 is performed by the PC name / Menu information sending packet 510 in S2204. Data to be displayed is sent to the section 22. On the other hand, if data other than data existing while “Start” and “End” are attached to the “start / end position” of the PC name / Menu information DB 601, the data is not sent in S 2204.

  In step S <b> 2205, the information on the client computer whose polling has stopped disappears from the display screen of the operation unit 22 of the composite printing apparatus 203. When polling from a client computer that is not displayed on the operation unit 22 of the composite printing apparatus 203 stops, the display screen of the operation unit 22 does not change anything in appearance. However, when the menu is scrolled up and down, such client computer information (PC name, etc.) is not displayed.

  FIG. 27 is a diagram for explaining the flow of processing before and after the composite printing apparatus 203 enters the sleep state.

  In S2301, since the condition of ST> Sleep setting time is satisfied, the composite printing apparatus 203 enters a state of entering sleep.

  In step S2302, a state monitoring interruption event 514 is issued from the composite printing apparatus 203 to the PC name / menu management PC 202. As a result, the polling monitoring task in FIG. 21 skips the update status monitoring processing of the PC name / Menu information DB 601.

  In step S2303, the composite printing apparatus 203 transitions to a sleep state (Deep Sleep). In step S <b> 2304, the status inquiry packet 501 is sent from the client computer to the composite printing apparatus 203.

  In step S <b> 2305, the OK packet 503 is returned to the client computer by the proxy response system of the composite printing apparatus 203.

  In step S2306, the operation unit 22 of the composite printing apparatus 203 is operated to cancel the sleep state.

  In step S2307, the composite printing apparatus 203 issues a status monitoring resume event 515 to the PC name / menu management PC 202. At this time, the PC name / Menu management PC 202 recalculates the value of the polling packet arrival monitoring variable N according to the time of sleep or the transition from the sleep state to the return from the sleep state. The PC name / Menu management PC 202 monitors the update status of the PC name / Menu information DB 601 after receiving the status monitoring resume Event 515, but deletes information related to the client computer that has not been updated in N seconds. . Although not shown here, if data that exists between “Start” and “End” in the “start / end position” of the DB 601 is deleted, the data to be displayed is stored in the packet 510. The information is sent from the PC 202 to the composite printing apparatus 203 and the display is updated.

  In step S <b> 2308, a status inquiry packet 501 is issued from the client computer to the composite printing apparatus 203. This is a packet meaning normal status inquiry. In step S2309, the composite printing apparatus 203 returns an OK packet 503 to the client computer. At the same time, the polling reception Event 511 is issued to the PC name / Menu management PC 202.

  In step S <b> 2310, the PC name / Menu management PC 202 issues a polling packet transfer request 507 to the composite printing apparatus 203. In step S2311, the composite printing apparatus 203 issues a response data_polling packet 1_508 to the PC name / Menu management PC 202. When receiving the response data_polling packet 1_508, the PC name / Menu management PC 202 matches the PC name / Menu information DB 601. The PC name / Menu information DB 601 in FIG. 6 is an example managed using an IP address as a key. However, the PC name / Menu information DB 601 is not particularly limited as long as the data can be uniquely referenced. As a result of matching with the PC name / Menu information DB 601, there is a matching key, so the update time of the key is updated to the current time. Thereafter, if there is nothing in particular, S2308 to S2311 are repeated.

  FIG. 28 is a diagram for explaining a flow of a series of processing until a display screen 301 is displayed on the operation unit 22 of the composite printing apparatus 203 after a new scanner driver is installed in the client computer. Note that the PC name / Menu management PC 202 is not operating as a premise.

  In S2401, the scanner driver is installed on the client computer. At this time, it is assumed that the IP address of the client computer is “111.222.333.444”. In step S2402, when the installation of the scanner driver is completed, a status inquiry packet 501 is issued from the client computer to the composite printing apparatus 203. In the composite printing apparatus 203, the PC name / Menu information DB 601 is managed on the RAM 19, and is managed using the IP address as a key. As a result of matching the received data with the PC name / Menu information DB 601, if there is no matching key, the key is newly added.

  In step S2403, the composite printing apparatus 203 returns an OK packet 503 to the client computer. In step S <b> 2404, a PC name / menu information sending packet 502 is issued from the client computer to the composite printing apparatus 203. After installing the scanner driver, the scanner driver is set in advance so that the PC name / Menu information sending packet 502 is skipped in the next packet after skipping the status inquiry packet 501. As a result of matching the received data with the PC name / Menu information DB 601, if there is no matching key, the key is newly added. In most cases, an entry has been made in the PC name / Menu information DB 601 based on the processing result of the status inquiry packet 501, and therefore, only the additional Menu information is added. When processing is performed so far, information for one case is completed on the PC name / Menu information DB 601.

  In step S2405, the composite printing apparatus 203 returns an OK packet 503 to the client computer. In step S2406, information about the scanner driver newly installed in the client computer for the first time at this time can be displayed on the composite printing apparatus 203.

  According to the above-described embodiment, even when a memory or an external storage device that can sufficiently store a PC name, a menu character string, or the like as destination information to which data is sent by push scan cannot be secured in the image processing apparatus, User convenience during push scan can be improved.

[Second Embodiment]
FIG. 29 is a diagram showing a schematic configuration of an image processing system including an image processing apparatus according to the second embodiment of the present invention.

  In the second embodiment of the present invention, the configuration shown in FIG. 2 is the same as that of the first embodiment, and the same parts as those in the first embodiment are described using the same reference numerals. Is omitted. Only differences from the first embodiment will be described below.

  29 correspond to 202 to 207 in FIG. 1, respectively. The second embodiment is different from the first embodiment in that a polling control system is additionally mounted on the client computer 2505 and ON / OFF control of polling packet transmission is performed. Furthermore, it differs from the first embodiment in that it responds to an operation status inquiry from the PC name / Menu management PC 2502.

  Furthermore, in the second embodiment, an operation status inquiry system is additionally mounted on the PC name / Menu management PC 2502, and the first implementation is performed in that the client computer 2505 of a specific condition is directly inquired about the operation status. Different from form.

  FIG. 30 is a flowchart showing an installation process of the polling control system executed on the client computer. Note that the client computers 2504 to 2507, the composite printing apparatus 2503, and the PC name / menu management PC 2502 are connected via the network 201 (or the USB cable 213).

  In step S2602, a polling control system installation process is performed. Next, in step S2603, the polling control system is executed and a process request waiting state is entered. Since the polling control system is a system that can operate independently of other processes, even if the process of FIG.

  FIG. 31 is a flowchart showing details of the processing request waiting process of the polling control system executed in step S2603 of FIG. This process is registered in an OS (not shown) at the time of installation, and is automatically started every time the OS is restarted.

  In step S2702, the polling control system waits for a processing request. When any processing request is accepted, it is determined whether or not the processing request is an operation status inquiry (step S2703). The operation status inquiry is performed by transferring an operation status inquiry packet (not shown) from the PC name / Menu management PC 2502 to the client computer. If the processing request is an operation status inquiry, the process proceeds to step S2706; otherwise, the process proceeds to step S2704.

  In step S 2704, it is determined whether or not the processing request is an instruction to restart sending a polling packet using the status inquiry packet 501 or the PC name / menu information sending packet 502 transmitted from the client computer to the composite printing apparatus 2503. The sending resumption instruction packet is not shown. If it is a sending restart instruction packet, the process proceeds to step S2707; otherwise, the process proceeds to step S2705.

  In step S2705, it is determined whether or not the processing request is a polling packet transmission suspension instruction by the status inquiry packet 501 or the PC name / menu information transmission packet 502 transmitted from the client computer to the composite printing apparatus 2503. The sending interruption instruction packet is not shown. If it is a sending interruption instruction packet, the process proceeds to step S2708; otherwise, the process returns to step S2702.

  In step S2706, an OK packet indicating that the client computer is operating is returned to the PC name / Menu management PC 2502. The OK packet is not shown. Since the OK packet is not returned when the client computer is not operating, the PC name / Menu management PC 2502 can determine whether or not the client computer is operating based on whether or not there is an OK packet response. . Thereafter, the process returns to step S2702.

  In step S2707, it is determined that the processing request is a polling packet transmission restart instruction by the status inquiry packet 501 or the like transmitted from the client computer to the composite printing apparatus 2503. Then, the subtask that transmits the polling packet is resumed at the suspended interval of T seconds. Thereafter, the process returns to step S2702.

  In step S2708, it is determined that the processing request is a polling packet transmission suspension instruction by the status inquiry packet 501 or the like transmitted from the client computer to the composite printing apparatus 2503. Then, the subtask that transmits the polling packet at intervals of T seconds is interrupted. Thereafter, the process returns to step S2702.

  FIG. 32 is a flowchart showing the installation process of the operation status inquiry system executed on the PC name / Menu management PC 2502. Note that the client computers 2504 to 2507, the composite printing apparatus 2503, and the PC name / menu management PC 2502 are connected via the network 201 (or the USB cable 213).

  In step S2802, operation status inquiry system installation processing is performed. In step S2803, the operating status inquiry system is executed. This system is a system that can operate independently of other processes. Details of this processing will be described with reference to FIG.

  FIG. 33 is a flowchart showing details of the activation process of the operation status inquiry system executed in step S2803 of FIG. This process is registered in an OS (not shown) at the time of installation, and is automatically started every time the OS is restarted.

  In step S2902, the CPU 1 confirms the contents of the PC name / Menu information DB 601 managed on the PC name / Menu management PC 2502, and outside the data with “Start” and “End” in the “start / end position”. It is determined whether there is data located. In the example of the PC name / Menu information DB 601 in FIG. 6, 607, 608, and 609 correspond to this. If there is such data, the process proceeds to step S2903; otherwise, the process returns to step S2902. In order to prevent the CPU 1 of the PC name / Menu management PC 2502 from being wasted in a useless processing loop, an appropriate wait may be entered before returning to step S2902, and then returning to step S2902. .

  In step S 2903, an operation status inquiry packet is transmitted to the PC outside the data having “Start” and “End” in the “start / end position” on the PC name / Menu information DB 601. In the example of the PC name / Menu information DB 601 in FIG. 6, an operation status inquiry packet is transmitted to the PCs described in 607, 608, and 609 (the operation status inquiry packet is not shown). Then wait for the reply.

  In step S2904, it is determined whether a reply packet (OK packet) to the operation status inquiry packet from the client computer 2505 has been received. If the OK packet is returned, the process proceeds to step S2905. If the OK packet does not return within a certain time, the process returns to step S2902.

  In step S2905, since a reply packet (OK packet) to the operation status inquiry packet from the client computer 2505 is returned, the update time information of the DB 601 is updated with the current time of the PC name / Menu management PC 2502. Then, the process returns to step S2902.

  In the second embodiment, the internal processing of the processing flow of FIG. 15 is slightly changed, and will be described below. There is no change in the flow of the flow. The internal processing of the following parts is different.

  In step S1508, processing corresponding to the PC name / Menu information list update request 1Event 512 is performed. This event is issued from the composite printing apparatus 2503 when the operation of the operation unit 22 is performed by the composite printing apparatus 2503 and an instruction is given to scroll the screen displayed on the display screen 301 upward. . When this event is received, the PC name / Menu management PC 2502 refers to the PC name / Menu information DB 601 and searches for a place where “Start” and “End” are added to “Start / End Position”. If the total number of data registered in the PC name / Menu information DB 601 is equal to or less than the number that can be displayed on the display screen 301 at a time, the process ends without doing anything. When the total number of data registered in the PC name / Menu information DB 601 exceeds the number that can be displayed on the display screen 301 at a time, the following processing is performed.

  First, each of the data with “Start” and “End” is moved to the next lower data. At this time, a polling OFF instruction packet (not shown) is transmitted to the client computer 2505 indicated by the data with “Start” before moving. By this transmission, the subtask that transmits the polling packet at intervals of T seconds is interrupted in the client computer receiving it.

  Next, the data with the new “End” is put on the PC name / Menu information sending packet 510 and transmitted to the composite printing apparatus 2503. At this time, a polling ON instruction packet (not shown) is transmitted to the client computer 2505 indicated by the data with the new “End”. By this transmission, the subtask that transmits the polling packet at intervals of T seconds is resumed in the client computer that has received it.

  On the composite printing apparatus 2503 side, the uppermost data in the RAM 19 is erased, and the subsequent data are sequentially moved up one by one, and kept in a standby state with the lowest order left. The data transmitted here is displayed by being incorporated at this lowest level.

  After sending the PC name / Menu information, the process returns to step S1502 to receive various requests to the Menu management system.

  In step S1509, processing corresponding to the PC name / Menu information list update request 2Event 512 is performed. This event is issued from the composite printing apparatus 2503 when the operation of the operation unit 22 is performed by the composite printing apparatus 2503 and an instruction is given to scroll the screen displayed on the display screen 301 downward. . When this event is received, the PC name / Menu management PC 2502 refers to the PC name / Menu information DB 601 and searches for a place where “Start” and “End” are added to “Start / End Position”. If the total number of data registered in the DB is less than the number that can be displayed on the display screen 301 at a time, the process ends without doing anything. When the total number of data registered in the PC name / Menu information DB 601 exceeds the number that can be displayed on the display screen 301 at a time, the following processing is performed.

  First, the data with “Start” and “End” are moved to the data one level higher. At this time, a polling OFF instruction packet (not shown) is transmitted to the client computer 2505 indicated by the data with “End” before being moved. By this transmission, the subtask that transmits the polling packet at intervals of T seconds is interrupted in the client computer receiving it.

  Next, the data with the new “Start” is added to the PC name / Menu information sending packet 510 and transmitted to the composite printing apparatus 2503. At this time, a polling ON instruction packet (not shown) is sent to the client computer 2505 indicated by the new data with “Start”. By this transmission, the subtask that transmits the polling packet at intervals of T seconds is resumed in the client computer that has received it.

  On the composite printing apparatus 2503 side, the data at the lowest position in the RAM 19 is erased, and the data below it is sequentially lowered one by one, and the standby is made with the highest order empty. The data transmitted here is incorporated and displayed at the highest level. After sending the PC name / Menu information sending packet 510, the process returns to step S1502 to receive various requests to the Menu management system.

  In step S1516, processing when response data_polling packet 2_509 is received is performed. When this packet is received, it is first matched with the PC name / Menu information DB 601. The PC name / Menu information DB 601 in FIG. 6 is an example managed using an IP address as a key. However, the data is not particularly limited as long as the data can be uniquely referred to. If there is no matching key as a result of matching with the PC name / Menu information DB 601, the key is newly added. When adding, the information is simply added to the end of the DB, and the information about the start / end position is also updated. In most cases, since the entry is completed in the PC name / Menu information DB 601 based on the processing result of the response data_polling packet 1_508, it is only necessary to add the missing Menu information.

  When the menu information is added and the data is completed, the start / end position of the PC name / menu information DB 601 is also updated. If the added data is still an amount of data that can be displayed on the display screen 301 at a time, “Start” is set as the highest order data, and “End” is set as the lowest order data. If there is an amount of data that can be displayed on the display screen 301 once or more than before the addition, “Start” and “End” are not updated. At this time, if the newly added data is outside “Start” and “End”, a polling OFF instruction packet (not shown) is sent to the client computer 2505 indicated by the data. By this transmission, the subtask that transmits the polling packet at intervals of T seconds is interrupted in the client computer receiving it. Then, the process returns to step S1502 to receive various requests to the menu management system. By changing the correction in steps S1508, S1509, and S1516 from the process described in the first embodiment to the process described in the second embodiment, the following occurs.

  First, at the start / end position of the PC name / Menu information DB 601, a subtask that transmits a polling packet at intervals of T seconds operates only on the client computer 2505 corresponding to the data sandwiched between “Start” and “End”. To do. In other words, in the client computer 2505 corresponding to data not sandwiched between “Start” and “End”, the subtask that transmits the polling packet at intervals of T seconds is interrupted.

  Secondly, a case will be described in which the operation unit 22 is operated by the composite printing apparatus 2503 and the screen displayed on the display screen 301 is scrolled up and down to be displayed. In this case, in the client computer 2505 corresponding to the data disappeared from the display, the subtask that transmits the polling packet at intervals of T seconds is interrupted.

  Thirdly, a case will be described in which the operation unit 22 is operated by the composite printing apparatus 2503 and the screen displayed on the display screen 301 is scrolled up and down to be displayed. In this case, in the client computer 2505 corresponding to the newly displayed data, the subtask that transmits the polling packet at intervals of T seconds is resumed.

  In summary, in the processing of FIG. 33, the operating status inquiry system is used to inquire the client computer 2505 corresponding to the data that is not sandwiched between “Start” and “End” of the “start / end position” of the DB 601. It is carried out.

  A polling packet is transmitted at intervals of T seconds from the client computer 2505 corresponding to the data sandwiched between “Start” and “End” of the “start / end position” of the DB 601, and based on the information, the PC name / Menu The update time of the information DB 601 is updated.

  On the other hand, the client computer 2505 corresponding to data not sandwiched between “Start” and “End” in the “start / end position” of the DB 601 is inquired of the operation status by the operation status inquiry system, and the update time of the DB 601 is updated. Updated. Then, when the operation unit 22 is operated by the composite printing apparatus 2503 and the screen displayed on the display screen 301 is scrolled up and down and displayed, the start / end of the newly updated PC name / Menu information DB 601 is displayed. Also valid for position. In the first embodiment, since status inquiry packets 501 from all client computers are concentrated and sent to one composite printing apparatus 203, there is a concern that the processing load on the status inquiry packet 501 will increase. is there.

  In the second embodiment, the status inquiry packet 501 is constantly sent to the composite printing apparatus 203 for the number of units that can be displayed on the operation unit 22 (display screen 301) of the composite printing apparatus 2503 at a maximum. It is a point that can be suppressed to the client computer.

  According to the second embodiment, it is possible to limit the amount of state inquiry packets transmitted to a device such as the composite printing apparatus 203, so that it is possible to reduce the response load on the device. .

  In the first and second embodiments, the embodiment in which the present invention is applied to a composite printing apparatus having a scanner function has been described. However, the present invention is not limited to this. It goes without saying that the effects of the present invention can be obtained even when applied to devices and the like.
