This is advantageous in that it is possible to freely construct a useful system that can control the use and distribution of consumable parts safely.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram for explaining the configuration of a consumable part management system according to an embodiment of the present invention. In FIG. 1, a printer (hereinafter referred to as a printer) is used as an apparatus main body 100, and a toner cartridge is used as an example of a consumable part. This corresponds to an example of a consumable part management system according to the present invention.

  The system has a management center and a user site of a device manufacturer connected via a telephone line such as a public line or a dedicated line or a remote communication network 205 such as the Internet. In addition, a plurality of user sites are usually connected to one management center, and there can be a plurality of management centers. Here, only one management center and one user site will be described.

  The user site in the present embodiment is a user who uses an apparatus main body (for example, a printer). The management center is provided by a device manufacturer or a dealer, and is configured to manage the distribution of the apparatus main body and consumable parts.

  On the management center side shown in FIG. 1, reference numeral 205 denotes a remote communication network, which connects the computer 201 on the management center side and the apparatus main body 230 on the user site side via the gateways 202 and 204 so that they can communicate with each other.

  Note that a computer 201 for managing a database, which will be described later, is connected to the gateway 202 via a LAN as a window terminal for performing processing. In the computer 201, databases 211 and 212 described later are constructed. Further, a service module 220 is constructed in the computer 201 in order to perform processing on the management center side described later.

  In the user site 102, printers are connected to the gateways 202 and 204 connected to the remote communication network 205 via a LAN. The printer can access the remote communication network 205 via the LAN. The printer 100 also includes a device module 230 that performs processing to be described later.

  As described above, each device in the user site 102 and the management center 101 are connected at all times or as necessary, and can communicate with each other using a predetermined protocol.

  FIG. 2 is a block diagram illustrating a configuration of the computer 201 illustrated in FIG.

  In FIG. 2, a computer 201 executes various controls and procedures (for example, a service module 220 and a user module) described later by causing the CPU 301 to execute a program written in the ROM 307 or an OS or application program written in the RAM 302. Realize.

  A hard disk 303 stores areas for the databases 211 and 212 shown in FIG. 1, program files, and data files. Reference numeral 308 denotes a drive device, which is composed of, for example, a flexible disk drive or a CD-ROM drive, and loads a file stored in a storage medium such as a flexible disk or a CD-ROM into the RAM 302 and performs data processing. Further, a flexible disk or CD-ROM may function as the databases 211 and 212 shown in FIG.

  The storage medium set in the hard disk 303 or the drive device 308 functions as a file storage medium. The program file such as the service module 220 shown in FIG. 1 or the data files of the databases 211 and 212 shown in FIG. Can be remembered.

  In particular, the drive device 308 can exchange a storage medium such as a flexible disk or a CD-ROM, and can supply data and programs from the medium to the computer.

  An input device 309 includes a keyboard and a pointing device, and a user inputs various instructions and data. Reference numeral 304 denotes a display, and various screen displays and screen switching are executed under the control of the CPU 301 as a user interface described later.

  A LAN interface 306 is an interface circuit for connecting to the network LAN shown in FIG. A printer interface 305 is an interface for locally connecting a printer to the computer 201.

  A remote interface 310 is an interface circuit with a device such as a modem or a router for connecting to the remote communication network 205, and is used by the gateway 202 and the gateway 204 shown in FIG.

  Note that the remote communication network 205 is not limited to a normal telephone line, so if it is not a telephone line, an interface suitable for the communication network is used. With this configuration, the management center computer and the user site computer are connected to each other so as to communicate with each other.

  FIG. 3 is a cross-sectional view illustrating the configuration of the printing apparatus installed at the user site shown in FIG. 1, and is modulated based on image information input by an electrophotographic method, for example, by a process cartridge containing a storage chip. This is an example of a laser printer configured such that an image can be developed by forming an image of a laser beam on a photosensitive drum in a process cartridge via a scanning unit.

  In FIG. 3, paper for printing is supplied from either paper cassette 802 or 805 by paper feed rollers 803 and 806 and transport rollers 804 and 807. Which paper feed cassette is used is specified at the time of printing from a host computer or the like using this printer.

  The sheet passes through the registration roller 808 and under the toner cartridge 810, and the toner image formed on the photosensitive drum 811 is transferred to the sheet by the charge of the transfer roller 818.

  The toner image on the photosensitive drum was developed by attaching toner to an electrostatic latent image formed by a laser beam emitted from a laser scanner unit 809 and reflected by a reflecting mirror 817 and modulated by an image signal. Is. The sheet on which the toner image is transferred is heated by the fixing drum 812, and the melted toner is fixed on the sheet. The paper that has passed through the fixing roller is directed by the double-sided deflector 813 to enter the duplex unit 820 or to be discharged.

  When the sheet is discharged while being directed upward, the face-up / face-down selector 814 further moves in a predetermined direction in response to an instruction from the CPU 301, so that the discharge path is switched. When the paper is discharged face down, the paper is directed rightward in FIG. 3 and is discharged by the face down discharge roller 815 with the face printed on the face down discharge tray 816 facing down.

  On the other hand, when face-up discharge is selected, the printed surface is discharged from a face-up discharge port 819 onto a tray (not shown). The position of the face up / face down selector is detected by a sensor and output to the CPU 301 as a signal.

  On the other hand, when duplex printing is selected, the sheet that has entered duplex unit 820 is conveyed by conveyance roller 821 and is temporarily placed on duplex tray 826. The paper on which printing on one side is completed is conveyed from the double-sided tray by the feeding roller 822. The conveyed paper is once sent to the double-sided path 824, and when the trailing edge of the paper reaches the double-sided conveyance roller 823, the reversing deflector 825 whose center of rotation substantially coincides with the double-sided conveyance roller 823, Rotate until reaching path 828A. In this state, when the sheet is conveyed in the reverse direction (left side in the figure), the left end of the sheet is lifted by the deflector and is conveyed as it is by the double-sided path pickup roller 828 and reaches the registration roller 808. Thereafter, an image is formed by the same path and procedure as in normal printing.

  During duplex printing, the printing control is performed by an instruction from the printer driver of the host computer on the user site side. For example, in order to print efficiently, instead of printing and ejecting sheets one by one on both sides one by one, control is performed such that sheets are alternately supplied from the paper feed tray and the two-sided tray to the developing unit and printed alternately. There is a way.

  That is, the printing order is “first sheet table” → “second sheet table” → “first sheet back” → “third sheet table” → “second sheet sheet” → “fourth sheet table” → “3rd back” →… → “3rd back from last” → “Last 1 front” → “2nd back from last” → “Back of last 1” The front and back prints are alternately performed except that the front and back prints are continuous.

  The paper on which the front side is printed is sent to the duplex unit, and the paper on which the back side is printed is discharged as it is onto the paper discharge tray. That is, the paper on which the image is formed on the paper supplied from the paper feed tray is sent to the double-sided tray, and when the image is formed on the paper sent from the double-sided tray, the paper is discharged to the paper discharge tray. The

  The control at the time of duplex printing is not limited to this, and printing can be performed such that both sides are printed one by one and both sides are similarly printed on the next sheet. Such control can be switched by a command from the host computer.

  If multiple sheets can be placed on the double-sided tray, you can print on one side as many as the number of sheets that can be placed on the double-sided tray, and then sequentially remove the sheets from the double-sided tray and print them on the other side. . Again, if the host computer can know the capacity on the double-sided tray, the control method can be switched from the host computer.

  In response to a command from the host computer, the control unit 801 controls the entire printer. Furthermore, the duplex unit 810 is detachable, and information on whether it is attached or removed is detected by a sensor and passed to the host computer.

  Here, the housing is a cover that can be freely opened and closed on the cartridge 810, and the opening and closing of the cover can be detected by a sensor. If the cartridge is provided with a memory, means for reading and writing data is prepared for the memory.

  A sensor indicating that the remaining amount of toner in the cartridge 810 is exhausted is built in the cartridge, and the printer 100 receives a detection signal from the sensor and outputs a no-toner signal (toner LOW signal). . That is, the no-toner signal is a signal indicating that the remaining amount of toner has run out. The toner LOW signal is generated in response to a detection signal from the cartridge when the cartridge is provided with a remaining amount sensor.

  FIG. 4 is a block diagram illustrating the configuration of the control unit 801 shown in FIG. 3, and the same components as those in FIG. 3 are denoted by the same reference numerals.

  In FIG. 4, a ROM 606 stores a control program, font data, and the like for driving the printer, and the CPU 601 loads the program onto the RAM 602 and executes it, thereby realizing a printing operation. The device module 230 shown in FIG. 1 is an example of such a program file.

  The external memory 605 stores data supplied from the outside. The operation unit 607 is a panel integrated with the display unit, which displays a state and allows a user to perform a simple operation input.

  A host interface 603 is an interface for connecting a printer as a local printer such as a personal computer. The LAN interface 604 is an interface for connecting to the network LAN 2 and is connected to the Internet by a device such as a remote router connected to the LAN 2.

  The printing unit 608 is the engine mechanism itself shown in FIG. 3, and the cartridge 810 is detachably mounted at a predetermined position. The cartridge 810 includes a nonvolatile rewritable memory 810a.

  Along with the mounting of the cartridge 810, the memory 810a is electrically connected to the printer 100 or a control unit of the printer 100, and writing and reading can be performed from the CPU 601 or a CPU (not shown) locally provided in the printing unit 608.

  Data read from the memory 810a can be sent to the LAN or the host via the LAN interface 604 or the host interface 603.

  FIG. 5 is a diagram for explaining an arrangement example of the memory 810a shown in FIG. 3, which is arranged at a predetermined position of the process cartridge 810 (hereinafter simply referred to as the cartridge 810) and can be electrically connected to the wiring in the printer 100. It is configured.

  The cartridge 810 is mounted on the printer 100 as shown in FIG. A semiconductor memory 810a is attached to the cartridge 810, and is electrically connected to the printer main body when the cartridge is attached, so that reading and writing are possible.

  FIG. 6 is a diagram illustrating an example of data stored in the semiconductor memory 810a illustrated in FIG.

  As shown in FIG. 6, the semiconductor memory 810a stores a serial number 907 for identifying each cartridge (individual). The serial number 907 is written in advance at the time of manufacturing or shipping. If serial number 907 can be decompressed using a predetermined decompression program, serial number 907 may be encrypted and stored.

  In the system of this embodiment, the above data is held in the cartridge.

(Management Center)
In the database 211 provided in the computer 201 of the management center 101, by using the SCM system or the like, the shipping information of the apparatus main body that can be equipped with the consumable parts managed by this system, and the consumable parts (process cartridge) managed by this system are stored. Shipment information is managed in real time.

  FIG. 7 is a diagram for explaining an example of the consumable parts shipment management table 2111 and the consumable parts product ID table 2112 managed by the database 211 shown in FIG. 1, and the data structure of the database managed by the computer 201 of the management center 101 Corresponds to the example.

  In FIG. 7, reference numeral 2111 denotes a consumable parts shipment management table, in which the machine number ID, the product ID, and the shipping date and time are registered for each machine body of the shipped consumable parts. In addition, the date and time when the merge processing to the consumable parts usage management DB described later is executed is registered. 2112 is a consumable part product ID table. For each product ID, the type of the device main body compatible with the product and the lifetime of the product are defined.

  A database 212 (consumable parts usage management DB) provided in the computer 201 of the management center 101 manages the use of consumable parts products to be managed by this system in cooperation with the database 211.

  FIG. 8 is a view for explaining an example of the consumable part machine number ID table 2121 and the consumable part status ID table 2122 managed by the database 212 shown in FIG. 1, and data of the database managed by the computer 201 of the management center 101. This corresponds to a structural example.

  In FIG. 8, reference numeral 2121 denotes a consumable part machine number ID table, in which the machine number ID, status ID, and product ID are registered for each individual body of the consumable part. In addition, the expiration date and time calculated by the process described later is registered. A consumable part status ID table 2122 defines the status contents and whether or not a consumable part can be used in each status for each consumable part status ID.

  The above-described database 211 and database 212 are controlled by the service module 220 provided in the computer 201 of the management center 101. Hereinafter, the control process will be described.

<Consumable parts shipment status update processing at the management center>
In the present embodiment, the database 211 holds SCM real-time shipping information, but the database 212 is not. Therefore, the service module 220 needs to perform a consumable parts shipment status update process that reflects the latest information in the database 211 in the database 212.

  The interval for performing this update process is performed according to the actual period from when the consumable part is shipped until it arrives at the user site. For example, if it always takes a week or more for the delivery system to arrive from shipment, it may be performed every 6 days.

  FIG. 9 is a flowchart showing an example of a first data processing procedure in the consumable material management system according to the present invention, and corresponds to the database update processing procedure to be executed by the computer 201 of the management center shown in FIG. S1001 to S1011 indicate each step.

  When the computer 201 recognizes that it is the update request timing, this processing is started, the line number counter n is initialized to “1” (S1001), and the service module 220 reserves the consumable part product ID table 2111 secured in the database 211. (S1002), it is determined whether there is a record that is not yet reflected in the database 212 (S1003), and a record that is not reflected in the database 212 is extracted. It is determined whether or not the defined consumable part machine number ID already exists in the table 2121 (S1004), and for the existing consumable part machine number ID, the corresponding record is rewritten (S1005), and the process proceeds to step S1010.

  On the other hand, if it is determined in step S1004 that the record does not exist, a new record is created (S1006), and the contents of the consumable part machine ID field and consumable part product ID field in the record of the table 2121 are copied ( In step S1007, the expiration date / time is calculated from the shipping date / time in the database 211 and the lifetime in the table 2112, and the calculated expiration date / time is input in the expiration date / time field (S1008). (S1009), the process proceeds to step (1010).

  Then, it is determined whether or not the number n is the last row number of the table 2111 (S1010). If it is determined that the number is not the last row number, the row number counter n is incremented by “1” (S1011), and the process proceeds to step S1002. Return.

  On the other hand, if it is determined in step S1010 that it matches the last line number, the process ends.

  When the CPU 301 executes such a control procedure, the database 212 can be synchronized with a system that acquires shipping information in real time such as an SCM system.

<Transition of consumable parts management state of the device body>
On the other hand, in the printer 100 shown in FIG. 1, the device module 230 holds a consumable part status ID table as shown in FIG. 10, and determines the status of the consumable part and whether each status is in such a state. It is determined and a control method of the printing unit 608, that is, whether printing is permitted or prohibited is determined.

  FIG. 10 is a diagram for explaining the data structure of the consumable part status ID table managed by the device module 230 shown in FIG. 4, including consumable part status ID, consumable part status, and information indicating whether printing can be performed. Are managed by the device module 230.

  FIG. 11 is a diagram for explaining state transition of the status of consumable parts in the printer 100 shown in FIG.

  As shown in FIG. 11, the status ID value of the consumable part transitions to any one of “1” to “5” by the process of attaching / detaching the process cartridge by the user, and the value indicated by the ID is shown in FIG. As shown in the table, the device module 230 determines whether printing can be executed.

<Procedure for sending consumable parts availability inquiry procedure>
FIG. 12 is a flowchart showing an example of a second data processing procedure in the consumable material management system according to the present invention, and corresponds to, for example, a consumable component availability inquiry procedure on the printer 100 side shown in FIG. S1301 to S1308 indicate each step, and the control program for driving this procedure is the device module 230. The main body of the module is stored as a program in the ROM 606 shown in FIG. It is loaded into the RAM 602 and executed.

  First, after the time when the apparatus main body is activated or the consumable part is removed, such as when the power source is turned on or returned from the power saving state (S1301), a sensor in the printer 100 detects that the apparatus main body is equipped with a consumable part. (S1302), the device module 230 identifies the device number ID of the apparatus main body stored in the ROM 606 (S1303), and then determines whether or not the device number ID of the cartridge built in the semiconductor memory 810a can be identified. (S1304) If it is not identifiable (if it is not a regular cartridge), the process proceeds to step S1308, and the device module 230 displays an error on the display unit of the operation unit 607 (the CPU 601 displays the operation unit 607 in the text format shown in FIG. 13, for example).

The main body of the module is stored as a program in the hard disk 303 shown in FIG. 2, and is loaded into the RAM 302 by the CPU 301 and executed.

  First, the service module 220 searches the table 2121 on the database 212 for the consumable part machine number ID in the information sent from the apparatus main body, and determines whether there is a corresponding record (S2001). If there is no record, it is determined that there is a machine number ID error (S2007), and the corresponding ID shown in FIG. 20 is sent to the apparatus main body (printer) via the network (S2011).

  On the other hand, if it is determined in step S2001 that there is a corresponding record, the service module 220 obtains a consumable part status ID from the record, and stores a main product ID that is compatible with the consumable part having the ID in the table 2112. And is read from the apparatus main body transmission information (S2002), and it is determined whether the main body product ID is applicable (S2003). If not applicable here, it is determined that there is an incompatibility error (S2008), and the corresponding ID shown in FIG. 20 is sent to the apparatus main body (printer) via the network (S2011).

  On the other hand, if the service module 220 determines in step S2003 that it corresponds to the consumable part, the service module 220 refers to the expiration date / time field of the table 2121 and the status ID to determine whether it is before the expiration date / time (see FIG. S2004). If it is determined that the date is after the expiration date / time, it is determined that there is an expiration date error (S2009), and the corresponding ID shown in FIG. 20 is sent to the apparatus main body (printer) via the network. (S2011).

  On the other hand, if it is determined in step S2004 that the date is before the expiration date, it is determined whether the status is usable (S2005). If it is determined that the status is not usable, it is determined that the status error has occurred. Then, the corresponding ID shown in FIG. 20 is sent to the apparatus main body (printer) via the network (S2011).

  On the other hand, if it is determined in step S2005 that the status is usable, the consumable part is determined to be usable (S2006), and the corresponding ID shown in FIG. (S2011).

<Procedure for notification of availability of consumable parts to the main unit on the management server>
Next, the management server (computer 201) notifies the printer 100 of availability.

  The service module 220 holds a table as shown in FIG. 20, for example, for managing the determination result. By referring to this table, the service module 220 performs steps S2006 and 07 shown in FIG. , 08, 09, and 10 are sent to the apparatus main body via the network. Then, when either the determination result ID1 or the determination result ID = 2 to 4 shown in FIG. 20 is notified to the apparatus main body, the apparatus main body uses the consumable parts from the server device in response to an inquiry about whether or not the consumable parts can be used. The availability information is received, and the availability of the consumable part is controlled according to the received determination result ID.
