Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an electronic apparatus, in which a refill cartridge (consumable goods) or a replacement part that is accorded a right to emit greenhouse gas (GHG) is used for global environmental concerns. 
         [0003]    2. Description of the Related Art 
         [0004]    Today, global environmental conservation is demanded worldwide, and the global warming conference takes initiative in putting into force the emissions control on greenhouse gas such as carbon dioxide (CO 2 ). Under this circumstance, efforts are made to deal with reductions of CO 2  from general electronic apparatuses including printers, and pertinent patent applications are filed. 
         [0005]    For example, Unexamined Japanese Patent Application KOKAI Publication No. 2007-249563 is an example invention of an information processing apparatus including a printer, which allows setting of a target value of its consumption of a resource such as sheets of paper, forecasts a future amount of its resource consumption based on the current status of its resource consumption, stops consuming the resource if it is impossible to attain the target and issues a report for the target to be accomplished. 
         [0006]    Unexamined Japanese Patent Application KOKAI Publication No. 2002-006696 is an example invention that translates an amount of power consumed during a certain period of time of use of an image forming apparatus and an amount of a refill cartridge consumed by the image forming apparatus during the same period of time into CO 2 , encourages a recommendable mode for reducing CO 2  emissions, and forecasts improvement in CO 2  emissions. 
         [0007]    However, the examples described above, each of which either outputs a report for reduction of resource consumption or forecasts improvement in CO 2  emissions, can merely guide the user of the apparatus toward accomplishing the goal of tightening resource consumption by notifying the power consumption status, etc. to the user, or can merely notify a carbon dioxide emissions status corresponding to the use of the apparatus to the user to remind the user of a mode of use of the apparatus that will lead to reductions of emissions. That is, these examples do not propose an electronic apparatus according to the present invention, which can use a refill cartridge or a replacement part that is sold with a right to emit greenhouse gas attached (by the manufacturer), recognizes that a cartridge or a replacement part with such an emission right is mounted thereon, and displays the degree of its eco (ecology (global environmental protection)) accomplishment and guidance or navigation about greenhouse gas. 
       SUMMARY OF THE INVENTION 
       [0008]    The present invention provides a system for a manufacturer or a distributor of an electronic apparatus that emits greenhouse gas to share the expenses spent in contributing to carbon offset activities (including expenses for purchasing offset credits) with a user who purchases and uses the electronic apparatus, so that not only the manufacturer/distributor but the purchaser/user of the electronic apparatus may automatically participate in carbon offset activities and make cooperation and contribution to the global environmental protection. 
         [0009]    Here, carbon offsetting is a global environmental protection activity that aims for bringing carbon dioxide (CO 2 ) generation substantially to zero by offsetting CO 2  that is unavoidably generated from living and business activities by carrying out activities such as tree plantation, forest protection, clean energy projects, etc. that aim for CO 2  reduction or absorption

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0059]    The embodiments of the present invention will be explained below with reference to the drawings. 
       Embodiment 1 
       [0060]      FIG. 1  is a configuration diagram of a computer system including a printer according to the present embodiment. In  FIG. 1 , the printer  1  is connected to a plurality of personal computers (PC 1 , PC 2 , etc.) via a Local Area Network (LAN), and to a management center  2  via the Internet. The printer  1  is locally connected to a personal computer (PC 3 ) via a Universal Serial Bus (USB). The printer  1  receives print data from the personal computers (PC 1  to PC 3 , etc.) described above, which are host apparatuses. 
         [0061]    The printer  1  includes a controller unit  3 , an engine control unit  4 , an operation panel unit  5 , a high-pressure unit  6 , a motor control unit  7 , and various mechanisms. Such mechanisms include a drive unit  8 , a paper feed unit  9 , a head  10 , a double-side printing unit  11 , a belt unit  12 , a fixing unit  13 , a paper discharge unit  14 , a TC/DS  15 , a reader/sensor  16 , and a nonvolatile memory  17 . The printer  1  includes a power unit  18 , which is supplied with commercial power (AC 100V). 
         [0062]    The controller unit  3  receives print data supplied by a host apparatus (any of the personal computers (PC 1  to PC 3 ), etc.), converts the received print data into bitmap data, and sends it to the engine control unit  4 . The controller unit  3  controls the driving of each of the mechanisms described above to print out the bitmap data. The nonvolatile memory  17  records information about the number of times eco TCs have been continuously used (count data by which it is discriminated whether eco TCs are repetitively purchased and used), and a calculation of eco points, which serve as the basis by which an eco use degree described later is evaluated. Note that an “eco TC” is a toner cartridge  15   a , which is sold with a greenhouse gas emission right attached. 
         [0063]    The TC/DS  15  represents a toner cartridge  15   a  and a drum set  15   b . The toner cartridge  15   a  is a toner refill cartridge that includes a developer in which toner is stored and that is attachable and detachable to/from the printer  1 . The drum set  15   b  is a cartridge that includes a photoconductive drum and is attachable and detachable to/from the printer  1  (for replacement). The reader/sensor  16  is provided near the TC/DS  15  to sense whether the toner cartridge  15   a  and the drum set  15   b  are attached or detached (to sense their presence or absence and the presence or absence of an identification sign) and detect identification information about a greenhouse gas emission right (about whether they are the cartridges accorded a greenhouse gas emission right). 
         [0064]      FIG. 2  is a perspective diagram of the toner cartridge  15   a  and the drum set  15   b , when they are attached or detached to/from the printer  1 . The reference numerals used in  FIG. 2  indicate the positions at which the units explained in  FIG. 1  are disposed. The toner cartridge  15   a  and the drum set  15   b  are sold with a greenhouse gas emission right attached. This emission right is provided to a purchaser of the toner cartridge  15   a , etc. by a manufacturer/distributor of the toner cartridge  15   a , etc., who has bought, as Certified Emission Reduction (CER), on behalf of the user, the (emission) right that amounts to greenhouse gas that is generated when the power, which is to be consumed by the printer  1  during a period in which the printer  1  operates using a cartridge attached by the user, is generated (by a power plant). The printer  1  includes an identifying unit that identifies that the article attached to the printer  1  is the toner cartridge  15   a  or the drum set  15   b  with an emission right. The printer  1  confirms the number of times replacements of refill cartridges have been done, which is identified by the identifying unit, (based on use management information recorded in a nonvolatile storage unit such as an HD), displays an evaluation of an eco use degree (whether eco refills are frequently/continuously used), and displays advice or navigation about ecology. 
         [0065]    Certified Emission Reduction (CER) mentioned above is an emission quota (credit) earned in the framework of the Clean Development Mechanism (CDM), and issued for an amount of emission reduction achieved by a CDM project, which amount is determined by a designated institution of the United Nations and verified by the CDM board of directors. 
         [0066]    The identification information about accordance of an emission right to the toner cartridge  15   a , etc. is in the form of pasting of a barcode label or a QR code™ label, mounting of a memory IC, attaching of a Radio Frequency Identification (RFID) tag, or the like. Hence, different types of identification information to be provided to the toner cartridge  15   a , etc. require different configurations of the reader/sensor  16 . For example, in a case where a barcode label or a QR code label is pasted on the toner cartridge  15   a , etc. as a means to provide identification information indicating that the toner cartridge  15   a , etc. are accorded a GHG emission right, a known label sensor (reader) is used. In a case where a memory IC is mounted as a means to provide identification information indicating that the toner cartridge  15   a , etc. are accorded a GHG emission right, a reader (control circuit) that reads out data from the memory IC (via a connector that, when the cartridge is attached, connects the printer body (or the controller in the printer body) to the memory IC in the cartridge in a manner that enables data to be send and received therebetween) is used. 
         [0067]    In a case where an RFID tag is used as a means to provide the toner cartridge  15   a , etc. with identification information indicating that the toner cartridge  15   a , etc. are accorded an GHG emission right, an RFID tag (RFID sheet) that emits recognition information is pasted on the toner cartridge  15   a , etc. The RFID sheet is pasted at a position that will be at a predetermined (communicable) distance from an antenna on a printer control board mounted in the printer  1  when the toner cartridge  15   a , etc. are attached to the printer  1 . The RFID sheet (RFID tag) and the reader/sensor  16  (receiver), which is disposed on the printer control board, contactlessly communicate with each other via the antenna. 
         [0068]    A process operation of the present example having the above-described configuration will be explained below. 
         [0069]      FIG. 3  is a flowchart that explains the process operation of the present example. In  FIG. 3 , it is first determined whether attachment of a cartridge or replacement of cartridges has been performed (step (hereinafter “S”)  1 ). In this determination, it is determined whether the user has replaced the toner cartridge  15   a  with a new one in a case where, for example, the printer  1  has been used to perform printing operations according to print data sent from the host apparatuses (the personal computers (PC 1  and the like)), and consequently the toner stored in the toner cartridge  15   a  has been consumed and become short. 
         [0070]    Hence, in a case where attachment of the toner cartridge  15   a  or replacement of cartridges has not been performed (S 1 ; NO), the process operation of the present example will not be performed. On the other hand, in a case where attachment of the toner cartridge  15   a  or replacement of cartridges has been performed (S 1 ; YES), it is determined whether the attached or replaced new toner cartridge  15   a  is a cartridge accorded a greenhouse gas emission right described above (S 2 ). This determination is to confirm, by using the reader/sensor  16 , that the identification information described above is provided on the toner cartridge  15   a.    
         [0071]    In a case where the toner cartridge is not the toner cartridge  15   a  accorded a greenhouse gas emission right (S 2 ; NO), an eco point P is decremented (S 3 ). The eco point P is the basis of evaluating the degree of cooperation in reducing greenhouse gas, and greenhouse gas reduction is evaluated based on the eco point P in a way described later. 
         [0072]    On the other hand, in a case the determination (S 2 ) finds that the attached or replaced new toner cartridge  15   a  is a product with a greenhouse gas emission right (S 2 ; YES), it is further determined whether the cartridge is an unused product or not (S 4 ). In a case where the attached cartridge is not an unused product (S 4 ; NO), the eco point P is incremented (S 5 ). On the other hand, in a case where the attached cartridge is an unused product (S 4 ; YES), the number of times N eco TCs have been continuously used, which is stored in the nonvolatile memory  17 , is read out (S 6 ), and N×P, which is a continuous use eco point, is added (S 7 ). That is, the eco point P is multiplied by the number of times N, and the product N×P is added to the eco point. After this, the number of times N eco TCs have been continuously used is incremented to N+1 (S 8 ). 
         [0073]    Next, evaluation of an eco use degree is performed (S 9 ). The evaluation of the eco use degree is performed according to the result of calculation of the eco point. In a case where toner cartridges  15   a  with an emission right have been continuously used, the evaluation point will be high as can be understood from the above calculation manner, and in a case where not many toner cartridges  15   a  with an emission right have been used, the evaluation point will be low. Hence, the frequency of use of toner cartridges  15   a  with an emission right determines the evaluation of the eco use degree. The eco point calculation manner described above is an example, and any calculation manner may be used as long as it can evaluate the frequency of use of eco TCs. 
         [0074]    Next, according to the evaluation result, the evaluated eco use degree is displayed on a display device provided to the operation panel unit  5 , and navigational guidance is displayed (S 10 ).  FIG. 4  is a diagram showing a display example on the display device of the operation panel unit  5 , which is an example of when the evaluation of the eco use degree is high, and indicates, for example, that “Thank you for your great contribution to green house gas reduction.” On the other hand, when the evaluation of the eco use degree is low, for example, a message that “You are not cooperative to greenhouse gas reduction. We would strongly appreciate your cooperation to global environmental improvement based on eco product use” is displayed. 
         [0075]    Next, the evaluation result of the eco use degree is sent to the personal computer (PC 1 ), the host apparatus, via, for example, a LAN, so that the evaluation result may be summed (S 11 ). 
         [0076]      FIG. 5  is a diagram that explains the summing process. The personal computer (PC 1 ) siphons eco use mode logs from the printer  1  and displays them on the display. For example, in the example of  FIG. 5 , an eco status tab is displayed, under which the current year&#39;s achievements of each printer are displayed as a cumulative amount of power, its equivalent translated into a CO 2  amount, a number of sheets printed, a rate of double-side printing use, a rate of multipage printing use, and a rate of toner saving use. Note that the personal computer (PC 1 ) manages sheets of paper not only in the eco use mode described above, but in an ordinary manner. 
         [0077]    The operation panel unit  5  of the printer  1  of the present example has a power saving button  20  by which the printer  1  is switched to a power saving mode operation. For example, by an operator giving a long press to the power saving button  20 , a plurality of eco mode terms can be changed simultaneously by one operation to predetermined settings that are the most preferable, and the printer driver of the personal computers (PC 1 , PC 2 , etc.) that are connected to the printer  1  via the LAN is notified of the simultaneous eco mode setting. That is, the printer of the present invention has a plurality of terms by which an eco mode is set, including, for example, a batch printing feature, a double-side printing feature, a multipage printing (2-in-1 printing, N-in-1 printing) feature, a toner saving feature, etc., and these terms are not set ready one by one. Instead, only one long press of the power saving button  20  enables the plurality of terms related to the eco mode of the printer driver to be forcibly set simultaneously. 
         [0078]    In the example described above, the evaluation result of the eco use degree is sent to the personal computer (PC 1 ), but it may be sent to the management center  2  via the Internet, so that the management center  2  may sum the eco achievements of the printer that exists on the net. 
         [0079]    In the example described above, the evaluation of the eco use degree is displayed on the operation panel unit  5 , but it may be printed out as a printed output (sheet  19 ) as shown in  FIG. 6 . Further, as shown in  FIG. 7 , a young leaf mark may be printed. In a case where the evaluation of the eco use degree is high, many young leaf marks may be printed, with a special mark  19   a  printed on part of the young leaf marks to indicate that the evaluation of the eco use degree is high (that an eco product with an emission right has been used to perform this printing). 
         [0080]    In the description of the present embodiment, the toner cartridge  15   a  that is sold with a greenhouse gas emission right accorded has been explained as a refill product that the user of the printer has to purchase after a certain period of time of use. However, not only a refill product but a replacement part such as the drum set  15   b , which the user will purchase and attach to the printer after a predetermined period of time elapses may be sold with a greenhouse gas emission right accorded, and an ecology contribution display may be output on the operation panel unit  5  based on the number of times such replacement parts have been replaced, i.e., the use of the drum set  15   b . That is, replacement parts with an emission right may be the structural parts in the printer that require regular replacement, for example, the belt unit, the fixing unit, the print head unit, etc., and may be anything as long as it is purchased by the user at his/her cost for using the printer. 
         [0081]    As described above, the present example aims for making the user more conscious of greenhouse gas reduction, by using the toner cartridge  15   a  and the drum set  15   b  with an emission right as refill cartridges (refill units), evaluating greenhouse gas emissions based on the use status of these cartridges, displaying the evaluation on the operation panel unit  5 , and printing the evaluation on a sheet of paper. 
         [0082]    The printer used in the present example is not limited to the electrophotographic type described above, but may be an inkjet type, a thermal transfer type, etc. The objective refill cartridge may not necessarily be the toner cartridge  15   a  or the drum set  15   b , but may be an ink ribbon, a receptacle cartridge for sheets of paper, etc. 
         [0083]      FIG. 8  is an example in which the present invention is applied to a thermal transfer type printer. In this configuration, a thermal ribbon  30  is attachable and detachable to/from the printer  31 , and when the thermal ribbon  30 , which is accorded an emission right, is attached to an attachment section  32  of the printer  31 , an unillustrated reader/sensor provided in the printer  31  detects that the thermal ribbon  30  with an emission right is attached on the printer. In this case, the printer  31  performs printing operations, measures the number of times of replacements each time the thermal ribbon  30  with an emission right is replaced with a new one, displays an evaluation of an eco use degree on a display unit  33 , and displays guidance or navigation about ecology. 
         [0084]      FIG. 9  is an example in which the present invention is applied to an inkjet type printer. In this configuration, an ink bottle cartridge (ink refill)  34  is attachable and detachable to/from the printer  35 , when the ink bottle cartridge (ink refill)  34 , which is accorded an emission right, is attached to an attachment section of the printer  35 , a reader/sensor provided in the printer  35  detects the emission right. In this case, the printer  35  performs printing operations, measures the number of times of replacements each time the ink bottle cartridge  34  with an emission right is replaced with a new one, likewise displays an evaluation of an eco use degree on a display unit  36 , and displays guidance or navigation about ecology. 
         [0085]    In a case where replenishment sheets are sold in the form of a cartridge, the replenishment sheet cartridge may be sold with an emission right. Such a cartridge may be attached to the paper feed section of a printer and the printer may measure the number of times such cartridges are attached. This enables the printer to display an evaluation of an eco use degree and guidance or navigation about ecology on its display unit. 
         [0086]    Note that the objective electronic apparatus may not necessarily be a printer described above, but the present invention can be applied to OA apparatuses such as a facsimile apparatus, etc. that use a refill cartridge, and to a wide variety of industrial instruments. 
         [0087]    Further, the present invention may be embodied in a mode that a battery for an electronic apparatus that runs on a battery is sold with an emission right and the electronic apparatus discriminates use of a battery with an emission right and displays an ecology contribution degree. 
         [0088]    For example, a battery for an electronic apparatus that runs on a battery, such as a cellular phone, a digital camera, a portable electronic apparatus, etc. may be sold with a greenhouse gas emission right accorded as in the embodiment described above, and a function for identifying that a battery is accorded a greenhouse gas emission right may be provided to the electronic apparatus as in the embodiment described above. For example, the manner to accord may be printing a barcode label on the battery or pasting an RFID label on the battery. Correspondingly, a reader that reads the identification information may be provided at the battery attachment portion of the electronic apparatus body. When the reader reads information that indicates that the attached battery is a battery accorded a greenhouse gas emission right, the electronic apparatus may present the user with a display of a degree of contribution to cooperation in a global environmental enhancement activity or a display of an acknowledging message by using a display device or the like or present the user with such information by audio and manage accumulation of eco cooperation points according to the features of the electronic apparatus. In this way, the user of an objective apparatus can receive various advantages, such as benefits according to the quantity of eco points, including a discount of the sales price of a replacement/refill product, free-of-charge pickup of a used-up refill product, etc., and can help the global environmental protection activity. 
         [0089]    The electronic apparatus is not limited to a printer, a copying machine, etc., or to portable electronic apparatuses. Needless to say, the present invention can also be applied to a vehicle that requires a refill product or a replacement part, and emits greenhouse gas (the relationship between an electric vehicle and a battery, etc.) 
         [0090]    That is, the present invention may be embodied in a mode that a replaceable fuel cartridge for an apparatus that runs on a fuel is sold with an emission right accorded, and the apparatus identifies a fuel cartridge with an emission right and displays an ecology cooperation degree. 
         [0091]    The refill cartridge may be a product that requires regular replacement as described above, and the eco use status of each user may be managed and evaluated, so that an excellent user may receive benefits such as discount sales of a refill cartridge or a product that requires regular replacement, etc. 
         [0092]    By utilizing such a system that contributes global environmental enhancement according to the present invention, a user of an electronic apparatus or a refill product/replacement product can greatly contribute to greenhouse gas reduction and hence to global environmental enhancement without participating in a special cooperation activity or shouldering a huge financial burden. 
       Embodiment 2 
       [0093]    Next, the Embodiment 2 of the present invention will be explained. 
         [0094]    According to the present embodiment, a printer having global environmental enhancement features displays a degree of accomplishment of a greenhouse gas reduction goal according to the use status of these features on a display of an operation panel, and gives navigation that helps the operator accomplish the reduction goal by means of display on the operation panel. A detailed explanation will now be given. In the present example too, explanation about a case in which the electronic apparatus to be used is the printer shown in  FIG. 1  will be given. The global environmental enhancement features are a “power saving” feature, a “paper saving” feature, and a “toner saving” feature, which are to be described later. 
         [0095]    In the present example, first, an eco goal level that can be accomplished with the use of the global environmental enhancement features possessed by the printer according to the present invention is entered from the operation panel unit  5 .  FIG. 10  is a diagram that shows an example of terms to which eco goal levels are set. The terms include a relative evaluation mode and an absolute evaluation mode, to each of which an eco goal level is set. The relative evaluation mode is a mode that is independent of the number of sheets of paper printed by the printer  1 , and in which mode, the degree of how an eco activity is accomplished is visibly indicated based on, for example, a result of evaluation of execution of a use mode (global environmental enhancement feature  1 ) of the printer in which the printer performs a printing operation by saving power required to print a sheet, a use mode (global environmental enhancement feature  2 ) of the printer in which the printer performs a printing operation by saving sheets of paper, and a use mode (global environmental enhancement feature  3 ) of the printer in which the printer performs a printing operation by saving toner. Meanwhile, the absolute evaluation mode is a mode that is dependent only on the number of sheets of paper printed, and in which mode, a degree of accomplishment of an eco activity, which is to save the absolute amount of use of the printer, is evaluated and displayed. 
         [0096]      FIG. 10  shows how eco goal levels are set for the absolute evaluation mode. Specifically, the apparatus user sets beforehand a standard number of sheets used (for example, it is supposed here that 10,000 sheets per month is the normal amount of use). Based on this, the lowest goal level is set to “the set value—10%” (i.e., a use of 9,000 sheets per month), the middle goal level is set to “the set value—20%” (i.e., a use of 8,000 sheets per month), and the highest goal level is set to “the set value—30%” (i.e., a use of 7,000 sheets per month) as the values of the reduction goal. 
         [0097]      FIG. 11  shows an example of terms to which an eco goal level (degree of accomplishment) is set in the relative evaluation mode.  FIG. 11  shows an example setting of each goal level for eco mode use with respect to a predefined standard, about three factors for CO 2  reduction, namely “power saving”, which is a global environmental enhancement feature  1 , “paper saving”, which is a global environmental enhancement feature  2 , and “toner saving”, which is a global environmental enhancement feature  3 . In the global environmental enhancement feature  1 , a batch printing manner is used to buffer a plurality of print jobs that are entered at random intervals to process the jobs simultaneously and thereby to reduce the power consumed by the printer, which leads to GHG emissions reduction. In the global environmental enhancement feature  2 , an N-in-1 printing manner, by which the contents of N pages are printed collectively in one page, is used to reduce the amount of sheets used and thereby to reduce the power required to fabricate sheets, which leads to GHG emissions reduction. In the global environmental enhancement feature  3 , a toner saving mode, in which the printing darkness is reduced, is used to reduce the amount of toner used and to reduce the power required to fabricate toner, which leads to GHG emissions reduction. For example, as regards the “power saving” factor (eco by batch printing), an eco level is set based on the number of sheets that are to be printed simultaneously in a batch, and based on a standard case in which the number of sheets to be printed simultaneously in a batch is one (1PJ), a case in which the number of sheets to be printed simultaneously in a batch is three (3PJ) is set as “level 1”, and a case in which the number of sheets to be printed simultaneously in a batch is five (5PJ) is set as “level 2”, and a case in which the number of sheets to be printed simultaneously in a batch is ten (10PJ) is set as “level 3”. Here, “*PJ” indicates the batching degree of the batch printing mode, which indicates how many printing jobs that occur in the sequential order of page numbers are batched for each printing operation (batch printing can widen the interval between the batch jobs and lengthen the sleep period of the printer and thereby can reduce the power consumed by the printer). The value*indicates the number of sheets that are to be printed in a batch. That is, normally, when print data is entered and even if the print data contains only one page, a printing operation is performed for that entered one page (which is 1PJ). Meanwhile, nPJ is a power saving mode in which a printing operation is not started until print data that are entered pile up to n pages. (The standard value is 1PJ, which is a mode in which power is not saved (restriction on CO 2  emissions is low.) (n is a positive integer.) 
         [0098]    To further detail  FIG. 11 , the printer of the present example is supposed to consume 200 Wh power for printing 100 sheets, if the printing operation is performed in the 1PJ printing mode that is set as the standard. When calculating the amount of CO 2  to be emitted per sheet to be printed based on these values, since the power required to print one sheet is about 2 Wh, the answer (i.e., CO 2  emission amount, which is to be used as a standard value) is 2 Wh×a (where a indicates the amount of CO 2  emitted per 1 Wh power). Accordingly, with reference to this standard value, in a case where the “power saving” factor is set to “level 1” in which the printing mode is 3PJ, the amount of CO 2  emitted per sheet to be printed is (1.7 Wh×a)g. Likewise, in the case of “level 2” in which the printing mode is 5PJ, the amount of CO 2  emitted per sheet to be printed is (1.5 Wh×a)g. In the case of “level 3” in which the printing mode is 10PJ, the amount of CO 2  emitted per sheet to be printed is (1.0 Wh×a)g. Further, supposing that the amount of CO 2  reduction in the standard mode in which nothing special is done is 0.00, the amount of CO 2  reduction in each case is (0.3 Wh×a)g in the case of “level 1”, (0.5 Wh×a)g in the case of “level 2”, and (1.0 Wh×a)g in the case of “level 3”, which are translated to a reduction rate of 15% in the case of “level 1”, 25% in the case of “level 2”, and 50% in the case of “level 3”, as can be seen from  FIG. 11 . 
         [0099]      FIG. 11  tells similar things about the “paper saving” factor (eco by N-in-1 printing by which the contents of N pages are printed collectively in one page). The printing modes of this factor include a standard mode, a “level 1” mode, a “level 2” mode and a “level 3” mode. In the standard mode, one page data is printed on only one side of a sheet and the back side is left unprinted (no saving is accomplished). In the “level 1” mode, one page data is printed on each side of a sheet, so data is printed on both sides of a sheet, thereby two page data is printed on one sheet (consumption of one sheet is saved with respect to the standard). In the “level 2” mode, two page data is multi-printed on only one side of a sheet and the back side is left unprinted (consumption of one sheet is saved with respect to the standard). In the “level 3” mode, two page data is multi-printed on each side of a sheet (consumption of three sheets is saved with respect to the standard). Supposing that the amount of CO 2  emitted per sheet for its fabrication is b gram, by saving the amount of sheets consumed, the “level 1” mode and the “level 2” mode reduce CO 2  emissions by b gram, which corresponds to saving of one sheet, and the “level 3” mode reduces CO 2  emissions by 3×b gram, which corresponds to saving of three sheets. To translate the reduction amounts into a reduction rate, the “level 1” mode and the “level 2” mode reduce CO 2  that is generated when a sheet is fabricated by 50%, and the “level 3” mode reduces CO 2  by 75%, as is explained in  FIG. 11 . 
         [0100]      FIG. 11  also tells similar things about the “toner saving” factor (eco by a printing operation that uses a toner saving mode). With respect to a standard printing mode that does not employ toner saving (toner saving printing), “level 1” is set as a 15% toner saving mode (a mode in which printing is performed at a printing darkness that is 15% less than the standard to save toner), “level 2” is set as a 30% toner saving mode (a mode in which printing is performed at a printing darkness that is 30% less than the standard to save toner), and “level 3” is set as a 50% toner saving mode (a mode in which printing is performed at a printing darkness that is 50% less than the standard to save toner). Supposing that d gram of toner is consumed per sheet when the sheet is printed at the standard darkness and that c gram of CO 2  is generated during a toner fabrication process for fabrication of 1 gram of toner, a standard printing operation that does not employ a toner saving mode generates c×d gram of CO 2 , while a “level 1” mode operation can prevent 15% of that amount, i.e., c×d×0.15 gram of CO 2  from being generated, a “level 2” mode operation can prevent 30% of that amount, i.e., c×d×0.3 gram of CO 2  from being generated, and a “level 3” mode operation can prevent 50% of that amount, i.e., c×d×0.5 gram of CO 2  from being generated, as is explained in  FIG. 11 . 
         [0101]    Hence, the invention of the Embodiment 2 is to evaluate the user&#39;s manner of using the printer in terms of whether the user uses the printer in eco-conscious manner based on the above-described three features (power saving, paper saving, toner saving) of the printer that will lead to GHG emissions reduction, and to show the user by display etc. what degree the user has accomplished of the eco level that the user has beforehand selected and set as the goal and what are preferred as steps to take according to the accomplishment status. 
         [0102]    Then, in the present example, the eco level goal is divided into three stages, namely “level 1” to “level 3”, and the user can freely select a goal. Based on the goal level that is selected beforehand, an eco use degree (a contribution degree that indicates the level of use of the printer with an eco-cooperative action) is evaluated in the subsequent printing operations. 
         [0103]      FIG. 12  is a flowchart that explains the process of the present example, and the process is performed on the basis that the eco level set by the user is the default status. Starting with this status, if no change is made to the set eco level (step (hereinafter, “ST”)  1 ; YES, ST 2 ; NO, and ST 4 ; NO), and if the print job is not an urgent one (that cannot take batch operation) (ST 6 ; NO), the PJ value that indicates the number of sheets to be batched for batch printing is checked. If print jobs have not piled up to the set PJ value, data indicating the number of sheets to be printed is written into an unillustrated nonvolatile memory such as a hard disk (HD) (ST 7 ; NO, ST 8 ). If print jobs have piled up to the set PJ value, corresponding print data are read out from the nonvolatile memory such as a hard disk (HD) and a printing operation is performed (ST 7 ; YES, ST 9 , ST 10 ). 
         [0104]    On the other hand, in case of emergency or in a case where an important document needs to be generated, a printing operation is performed upon change of the above default status. For example, in a case where it is necessary to print an important document and distribute it in the workplace, the paper setting is changed (ST 2 ; YES, ST 3 ), the toner setting is changed (ST 4 ; YES, ST 5 ), urgent printing is selected (ST 6 ), and then a printing operation is performed (ST 10 ). Further, in a case where it is necessary to distribute a makeshift document in the workplace urgently, a printing operation is performed (ST 10 ) with urgent printing selected (ST 6 ) and with the paper setting, etc. unchanged. 
         [0105]      FIG. 13  shows a case in which printing operations have been performed according to the process described above while the eco goal level is set to “level 1”, but the achievements resulting from the actual uses reveal that the user has used the intended manner at only 50% of the printing occasions as regards the “power saving” factor, likewise the user has used the intended manner at only 50% of the printing occasions as regards the “paper saving” factor, and the user has used the intended mode at only 60% of the printing occasions as regards the “toner saving” factor, and hence the total accomplishment degree is 53%.  FIG. 13  shows one example, and the eco accomplishment degree of 53% is a value obtained by dividing by 3 the total sum of the power saving accomplishment degree, the paper saving accomplishment degree, and the toner saving accomplishment degree shown in  FIG. 13  (average value). 
         [0106]      FIG. 14  is an example of the above calculation result being displayed on the display device of the operation panel unit  5 . The symbol as shown in  FIG. 14  points to a display corresponding to the relative evaluation mode and the symbol b shown in  FIG. 14  points to an example display corresponding to the absolute evaluation mode. In each case, the display shows a young leaf mark that is made incomplete according to the actual accomplishment degree, and the user can visually recognize the eco accomplishment degree of the printer  1 . 
         [0107]    Likewise as described above, young leaf marks may be printed out. In a case where the evaluation of the eco use degree is high, many young leaf marks may be printed and a special mark may be printed on part of the young leaf marks. 
         [0108]      FIG. 15  shows examples in which a diagnosis and advice are given for each of the factors described above. For example, in the example shown in  FIG. 15A , the evaluations displayed in the relative evaluation mode show that “the accomplishment degree (rate) is 60%” as the evaluation of the “power saving” factor and that “you have used 1PJ mode (1PJ printing) many times”, etc., and the evaluations displayed in the absolute evaluation mode, which considers only the number of sheets printed, show that “you have used (consumed) many sheets”, etc. As regards paper, toner, etc. too, a display corresponding to the accomplishment degree is given as shown in  FIG. 15A . 
         [0109]    The ecology navigation feature shown in  FIG. 15B  is to display guidance about in what way the goal can be accomplished with respect to the above evaluations given for the relative evaluation mode and the absolute evaluation mode. For example, in a case where the evaluation on “power saving” is that “you have used 1PJ printing many times”, the navigation to be displayed may be that “you are encouraged to print at 2PJ or higher power saving setting (you are encouraged to print at 2PJ or higher power setting)”. As regards other factors too, a corresponding display can be given. 
         [0110]    The eco diagnosis shown in  FIG. 15C  is to give a diagnosis on an individual basis and on a group basis separately, and a display corresponding to the accomplishment degree is given for the relative evaluation mode and the absolute evaluation mode. 
         [0111]    It is desired that the goal accomplishment status display and the navigation described in the Embodiment 2 be given under a state in which it is recognized that the refill product/replacement part or the like according to the Embodiment 1 (to which a greenhouse gas emission right is accorded) is attached on the printer body. 
         [0112]    In the explanation of the embodiments described above, CO 2  has been the example of greenhouse gas. However, the present invention is applicable to any other greenhouse gas, for example, methane (CH 4 ), nitrous oxide (N 2 O) (=dinitrogen monoxide), hydrofluorocarbon series (HFCs), perfluorocarbon series (PFCs), and sulfur hexafluoride (SF6). 
         [0113]    Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. The above-described embodiments are intended to illustrate the present invention, not to limit the scope of the present invention. The scope of the present invention is shown by the attached claims rather than the embodiments. Various modifications made within the meaning of an equivalent of the claims of the invention and within the claims are to be regarded to be in the scope of the present invention. 
         [0114]    This application is based on Japanese Patent Application No. 2008-158730 filed on Jun. 18, 2008 and including specification, claims, drawings and summary. The disclosure of the above Japanese Patent Application is incorporated herein by reference in its entirety.
