1. Field of the Invention
The present invention relates to an image forming apparatus having a Web (World Wide Web) browser installed thereon, which is capable of printing out image data obtained by the Web browser from Websites via the Internet or etc. and other image data; a billing method of the image forming apparatus; and a computer readable recording medium having a billing program recorded therein to make a computer execute processing.
2. Description of the Related Art
The following description sets forth the inventor's knowledge of related art and problems therein and should not be construed as an admission of knowledge in the prior art.
Among the image forming apparatuses such as MFPs (Multi Function Peripherals) that are multifunctional digital machines collectively having a plurality of functions, for example the copy function, the print function and the facsimile function, there exist some image forming apparatuses having a Web browser installed thereon, which is software to view Web pages and obtain image data from Websites.
Such image forming apparatuses generally have a counter that counts the number of printed sheets and bills a print fee according to the counter. Installation of the Web browser as mentioned above serves to print out image data obtained from Websites via the Internet or etc. and eventually create more opportunities for printing and promote print practice, which is one of the intentions thereof.
However, such a configuration also allows using the Web browser without using print services, which hardly provides the effect of promoting print practice.
Consequently, a function is added on the image forming apparatuses to bill to users, a usage fee for using a Web browser in addition to a print fee, in order to make a return on the cost for the Web browser and prevent unlimited use of the Web browser.
As disclosed in Japanese Unexamined Laid-open Patent Publication No. 2002-366471, there exists a technology to print Internet advertisement information together with personally-identifying information owned by a portable electronic device such as a cell-phone, and printer's environmental information, onto a print result of information owned by the portable electronic device. And thereby, an amount billed is reduced if such advertisement information is printed out.
And as disclosed in Japanese Unexamined Laid-open Patent Publication No. 2002-108578, there exists a technology to print an advertisement together with print data obtained from a user's owning terminal. And thereby, the user receives print services for free.
However, such a configuration to bill a usage fee for using a Web browser in addition to a print fee, requires users who intentionally use the Web browser for print services, to pay both a usage fee for using a Web browser and a print fee without discount benefits. Thus, installation of a Web browser produces the opposite effect against promoting print practice and it does not provide benefits for users who use the Web browser to use print services.
Furthermore, the technologies disclosed in the two publications described above do not provide a complete resolution against these inconveniences.
The description herein of advantages and disadvantages of various features, embodiments, methods, and apparatus disclosed in other publications is in no way intended to limit the present invention.

Like the billing processor 109, this Web browser portion 110 is also configured as a part of the function of the CPU 101.
Hereinafter, a billing procedure executed in the image forming apparatus 1 of
This billing procedure and the other billing procedures executed in the embodiments of the present invention to be described later, are executed by the CPU 101, according to an operation program recorded in the ROM 102 or another recording medium.
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee Per Unit Time: 10 yen for every 60 seconds).
In Step S01, the routine waits until use of the Web browser is started. If use of the Web browser is started (YES in Step S01), measurement of a time of using the Web browser is started in Step S02.
In Step S03, it is judged whether or not image data obtained by the Web browser via the IP network 3 is printed out. If it is not printed out (NO in Step S03), the routine proceeds to Step S05. If it is printed out (YES in Step S03), the print flag is turned to “ON” in Step S04, then the routine proceeds to Step S05.
In Step S05, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S05), the routine goes back to Step S03 and repeats Steps S03 through S05 until it is finished.
If use of the Web browser is finished (NO in Step S05), measurement of a time of using the Web browser is finished in Step S06, and it is judged in Step S07, whether or not the print flag indicates “ON”.
If the print flag does not indicate “ON” (NO in Step S07), since it means that image data obtained by the Web browser is not printed out, the routine proceeds to Step S08, in which a usage fee for using the Web browser for the measured time is calculated based on the usage fee per unit time set in advance. This calculated usage fee for using the Web browser is billed to a user who used the Web browser.
Meanwhile, if the print flag indicates “ON” (YES in Step S07), since it means that image data obtained by the Web browser is printed out, the routine proceeds to Step S09, in which a usage fee for using the Web browser is determined as “0”.
As described above, in this embodiment, a usage fee for using a Web browser, which is calculated based on a time of using the Web browser, is billed to a user. Meanwhile, if image data obtained by the Web browser is printed out, a usage fee for using the Web browser is not billed but only a print fee is billed. Thus, that could strongly encourage users to print image data obtained by a Web browser, and installation of a Web browser could enhance the effect of promoting print practice.
In the embodiment explained with
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee Per Unit Time: 10 yen for every 60 seconds). And also, a discount subject time of using the Web browser to print one sheet, should be set in advance thereon (for example, Discount Subject Time to Print One Sheet: 20 seconds).
In Step S11, the routine waits until use of the Web browser is started. If use of the Web browser is started (YES in Step S11), measurement of a time of using the Web browser is started in Step S12.
In Step S13, it is judged whether or not image data obtained by the Web browser via the IP network 3 is printed out. If it is not printed out (NO in Step S13), the routine proceeds to Step S15. If it is printed out (YES in Step S13), the number of the printed sheets is added to the value of the print counter in Step S14, then the routine proceeds to Step S15.
In Step S15, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S15), the routine goes back to Step S13 and repeats Steps S13 through S15 until it is finished.
If user of the Web browser is finished (NO in Step S15), measurement of a time of using the Web browser is finished in Step S16, and a billing subject time of using the Web browser, in other words, a total billing subject time is calculated in Step S17. In this example, the discount subject time of using the Web browser to print one sheet, is set in advance. Based on this time, a billing subject time of using the Web browser is calculated according to the following formula.
Billing Subject Time of Using Web Browser=Time of Using Web Browser−(Number of Printed Sheets×Discount Subject Time to Print One Sheet)
Subsequently, in Step S18, a usage fee for using the Web browser for the billing subject time is calculated based on the usage fee for using the Web browser per unit time, which is set in advance. As well as a print fee, this calculated usage fee for using the Web browser is billed to the user who used the Web browser.
As described above, in this embodiment, if image data obtained by a Web browser is printed out, a usage fee for using the Web browser is discounted depending on the number of printed sheets. Thus, installation of a Web browser could enhance the effect of promoting print practice.
In the embodiment explained with
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee per Unit Time: 10 yen for every 60 seconds). And also, a discount subject time of using the Web browser to print one sheet should be set in advance thereon for full-color printing and monochrome printing, respectively (for example, Discount Subject Time to Print One Sheet in Full-color: 20 seconds, Discount Subject Time to Print One Sheet in Monochrome: 10 seconds)
In Step S21, the routine waits until use of the Web browser is started. If use of the Web browser is started (YES in Step S21), measurement of a time of using the Web browser is started in Step S22.
In Step S23, it is judged whether or not image data obtained by the Web browser via the IP network 3 is printed out. If it is not printed out (NO in Step S23), the routine proceeds to Step S26. If it is printed out (YES in Step S23), the number of the sheets printed in full-color, is added to the value of the full-color print counter in Step S24, and the number of the sheets printed in monochrome, is added to the value of the monochrome print counter in Step S25. After that, the routine proceeds to Step S26.
In Step S26, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S26), the routine goes back to Step S23 and repeats Steps S23 through S26 until it is finished.
If use of the Web browser is finished (NO in Step S26), measurement of a time of using the Web browser is finished in Step S27, and a billing subject time of using the Web browser is calculated in Step S28. In this example, the discount subject time of using the Web browser to print one sheet is set in advance for full-color printing and monochrome printing, respectively. Based on these times, a billing subject time of using the Web browser is calculated according to the following formula.
Billing Subject Time of Using Web Browser=Time of Using Web Browser−(Number of Sheets Printed in Full-color×Discount Subject Time to Print One Sheet in Full-color)−(Number of Sheets Printed in Monochrome×Discount Subject Time to Print One Sheet in Monochrome)
Subsequently, in Step S29, a usage fee for using the Web browser for the billing subject time is calculated based on the fee for using the Web browser per unit time, which is set in advance.
As described above, in this embodiment, if image data obtained by a Web browser is printed out, a usage fee for using the Web browser is discounted depending on the number of sheets printed in full-color or the number of sheets printed in monochrome. Thus, installation of a Web browser could enhance the effect of promoting print practice.
In the embodiments explained with
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee per Unit Time: 10 yen for every 60 seconds). And also, a discount subject time of using the Web browser to print one sheet should be set in advance thereon for each sheet size (for example, Discount Subject Time to Print One A3 Sheet: 20 seconds, Discount Subject Time to Print One A4 Sheet: 10 seconds. Sheets are not limited to these sizes).
In Step S31, the routine waits until use of the Web browser is started. If use of the Web browser is started (YES in Step S31), measurement of a time of using the Web browser is started in Step S32.
In Step S33, it is judged whether or not image data obtained by the Web browser via the IP network 3 is printed out. If it is not printed out (NO in Step S33), the routine proceeds to Step S36. If it is printed out (YES in Step S33), the number of printed A3 sheets is added to the value of the A3 sheet print counter in Step S34, and the number of printed A4 sheets is added to the value of the A4 sheet print counter in Step S35. After that, the routine proceeds to Step S36.
In Step S36, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S36), the routine goes back to Step S33 and repeats Steps S33 through S36 until it is finished.
If use of the Web browser is finished (NO in Step S36), measurement of a time of using the Web browser is finished in Step S37, and a billing subject time of using the Web browser is calculated in Step S38. In this example, the discount subject time of using the Web browser is set in advance for A3 sheets and A4 sheets, respectively. Based on these times, a billing subject time of using the Web browser is calculated according to the following formula.
Billing Subject Time of Using Web Browser=Time of Using Web Browser−(Number of Printed A3 Sheets×Discount Subject Time to Print One A3 Sheet)−(Number of Printed A4 Sheets×Discount Subject Time to Print One A4 Sheet)
Subsequently, in Step S39, a usage fee for using the Web browser for the billing subject time is calculated based on the usage fee for using the Web browser per unit time, which is set in advance.
As described above, in this embodiment, if image data obtained by a Web browser is printed out, a usage fee for using the Web browser is discounted depending on a print sheet size. Thus, installation of a Web browser could enhance the effect of promoting print practice.
In this embodiment, if an error disabling use of a Web browser happens to occur during use of the Web browser, a usage fee for using the Web browser for the period of time elapsing from start of occurrence of the error until end thereof, is not billed.
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee per Unit Time: 10 yen for every 60 seconds).
In Step S41, the routine waits until use of the Web browser is started. If use of the Web browser is started (YES in Step S41), measurement of a time of using the Web browser is started in Step S42.
In Step S43, it is judged whether or not an error disabling use of the Web browser occurs during use of the Web browser. For example, such an error may be occurrence of a jam, in which an alert message is displayed and use of the Web browser is disabled until the error is resolved.
If such an error does not occur (NO in Step S43), the routine proceeds to Step S47. If such an error occurs (YES in Step S43), measurement of a time of using the Web browser is temporarily stopped in Step S44, and it is judged in Step S45, whether or not this error is resolved.
If this error is not resolved (NO in Step S45), the routine waits until it is resolved. If this error is resolved and use of the Web browser is enabled again (YES in Step S45), measurement of a time of using the Web browser is resumed in Step S46, then the routine proceeds to Step S47.
In Step S47, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S47), the routine proceeds to Step S43 and repeats from Steps S43 through S47 until it is finished.
If use of the Web browser is finished (NO in Step S47), measurement of a time of using the Web browser is finished in Step S48. Then in Step S49, a usage fee for using the Web browser for the billing subject time is calculated based on the usage fee for using the Web browser per unit time, which is set in advance.
Ad described above, in this embodiment, if an error disabling use of a Web browser happens to occur during use of the Web browser, a usage fee for using the Web browser for the period of time elapsing from start of occurrence of the error until end thereof, is not billed. Thus, that could eliminate user inconveniences caused due to occurrence of an error.
In this embodiment, a usage fee for using a Web browser is billed at a predetermined interval, and a usage fee to be billed is discounted depending on the number of times that a jam occurs for the predetermined interval.
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee per Unit Time: 10 yen for every 60 seconds).
Furthermore, a jam counter that counts the number of times that a jam occurs during a print operation should be provided in advance in the image forming apparatus 1. And also, a discount subject time per occurrence of a jam should be set in advance thereon (for example, Discount Subject Time per Occurrence of Jam: 10 seconds).
In Step S51 of
In Step S53, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S53), the routine waits until it is finished. If use of the Web browser is finished (NO in Step S53), measurement of a time of using the Web browser is finished in Step S54, and this measured time is added to the time of using the Web browser, which is previously measured, in Step S55. Then the routine proceeds to Step S56.
In this embodiment, a fee is billed at a predetermined interval, for example every month. Thus, it is judged in Step S56, whether or not a billing timing comes around. If a billing timing does not come around yet (NO in Step S56), the routine goes back to Step S51 and waits until use of the Web browser is started again.
If a billing timing comes around (YES in Step S56), a billing subject time of using the Web browser is calculated in Step S57.
In this embodiment, a fee to be billed is discounted depending on the number of times that a jam occurs for a predetermined time (for example, one month) that is subject to billing. The number of times of occurrence of a jam is counted by the jam counter as shown in the flowchart of
Billing SubjectTime of Using Web Browser=Total Time of Using Web Browser−(Number of Times of Occurrence of Jam×Discount Subject Time per Occurrence of Jam)
Subsequently, in Step S58, a usage fee for using the Web browser for the billing subject time is calculated based on the usage fee for using the Web browser per unit time, which is set in advance. After that, the value of the total time of using the Web browser is cleared in Step S59.
b) is a flowchart representing a count procedure to count the number of times of occurrence of a jam.
In Step S61, the value of the jam counter is cleared. Then, it is judged in Step S62, whether or not a jam occurs. If no jam occurs (NO in Step S62), the routine waits until it occurs. If a jam occurs (YES in Step S62), “1” is added to the value of the jam counter in Step S63, and it is judged in Step S64, whether or not to finish jam counting. Jam counting is finished if a billing timing comes around in Step S56 of
If the jam counter does not finish counting (NO in Step S64), the routine goes back to Step S62. If the jam counter finishes counting (YES in Step S64), the routine immediately terminates.
As described above, in this embodiment, a usage fee for using the Web browser is discounted depending on the number of times of occurrence of a jam, which would provide satisfactory services to users.
In this embodiment, if image data (also referred to as “file”) obtained by a Web browser then recorded in the memory 104 is printed out, a usage fee for using the Web browser is discounted.
A usage fee for using a Web browser per unit time should be set in advance on the image forming apparatus 1 (for example, it is set as “¥10/60” for the case of Usage Fee per Unit Time: 10 yen for every 60 seconds).
And also, a discount subject time to print such image data should be set in advance on the image forming apparatus 1 (for example, Discount Subject Time to Print File: 20 seconds).
In Step S71 of
In Step S73, it is judged whether or not use of the Web browser is still continued. If it is still continued (YES in Step S73), the routine waits until it is finished. If use of the Web browser is finished (NO in Step S73), measurement of a time of using the Web browser is finished in Step S74, and this measured time is added to the billing subject time of using the Web browser, in Step S75.
In Step S81 of
Subsequently, in Step S84, a usage fee for using the Web browser for the billing subject time is calculated based on the usage fee of using the Web browser per unit time, which is set in advance.
As described above, in this embodiment, if image data obtained by a Web browser then recorded in the memory 104 is printed out, a usage fee for using the Web browser is discounted. Thus, even if a user intends to print out image data obtained by a Web browser, after using the Web browser, he/she can receive a discount.
In this embodiment, if image data other than the one obtained by a Web browser among the image data (files) recorded in the memory 104 is printed out, a print fee is simply billed. Meanwhile, if image data obtained by the Web browser then recorded in the memory 104 is printed out, a print fee to be billed is discounted.
A unit value for printing one sheet should be set in advance on the image forming apparatus 1. And also, a discount rate (for example, 10%) for printing image data obtained by a Web browser should be set in advance thereon.
In Step S91, image data recorded in the memory 104 is printed out, according to user instruction. Then it is judged in Step S92, whether or not the printed image data is the one downloaded by the Web browser. For example, when image data downloaded by the Web browser from the Web server 2 is recorded in the memory 104, the obtained-by-Web browser flag is turned to “ON” and included in storage information of the image data. Thus, the above-mentioned judgment can be made easily only by checking this flag, when the image data is printed out.
If the printed image data is the one downloaded by the Web browser (YES in Step S92), the 10% print discount rate is applied for the case in Step S93, then the routine proceeds to Step S95. If the printed image data is not the one downloaded by the Web browser (NO in Step S92), the print discount rate is not applied for the case in Step S94, then the routine proceeds to Step S95.
In Step S95, a print fee is calculated according to the following formula.
Print Fee=Number of Printed Sheets×Unit Value×(100−Print Discount Rate)/100
As described above, in this embodiment, if image data other than the one obtained by a Web browser among the image data recorded in the memory 104 is printed out, a print fee is simply billed. Meanwhile, if image data obtained by the Web browser then recorded in the memory 104 is printed out, a print fee to be billed is discounted. Thus, that could encourage users to use a Web browser, and installation of a Web browser could enhance the effect of promoting print practice.
Each of the above-described examples is one embodiment of the present invention. However, the present invention is not limited thereto. For example, in the embodiments, a usage fee for using a Web browser is calculated based on a time of using the Web browser. Alternatively, it can be calculated based on volume of data obtained by the Web browser via the IP network 3, or based on both a time of using the Web browser and volume of data obtained by the Web browser.
