{Components of a digital multifunction device}
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing components of the digital multifunction device 1. The digital multi-function peripheral 1 is used for various purposes such as copying, faxing, and scanning. The digital multi-function peripheral 1 includes a setting unit 11, a reading unit 12, a printing unit 13, a reading sheet counter 14, a printing sheet counter 15, a display unit 16, and the like.

  The setting unit 11 is a functional unit for the user to perform settings such as copying, faxing, and scanning. The user sets the read original size, the print paper size, the enlargement / reduction ratio in the enlarged copy or reduced copy, and the like according to the use such as copy, fax, and scan. When the digital multi-function peripheral 1 is connected to a network (not shown), the setting unit 11 is notified of setting contents from a user terminal (not shown).

  The reading unit 12 is a functional unit that reads data from a read document when the user performs copying, fax transmission, scanning, or the like. The reading unit 12 receives a notification about setting contents from the setting unit 11. When the reading unit 12 completes the reading of one read original, the reading unit 12 notifies the read number counter 14 described later of the size of the read range in which the reading is completed.

  Here, the reading range size is a size obtained by dividing the printing paper size by the enlargement / reduction ratio. Therefore, depending on the enlargement / reduction magnification notified by the reading unit 12 from the setting unit 11, the reading range size and the read document size may not necessarily match.

  The printing unit 13 is a functional unit that prints data on printing paper when the user performs copying, fax reception, or the like. The printing unit 13 receives a notification about the setting contents from the setting unit 11. Then, when printing for one sheet of printing paper is completed, the printing unit 13 notifies the printing sheet counter 15 described later about the size of the printing paper for which printing has been completed.

  The reading sheet counter 14 is a functional unit that counts the number of sheets read by the reading unit 12. The reading number counter 14 includes a billing counter 141 and a physical counter 142, thereby counting the number of readings by two kinds of methods.

  The accounting counter 141 counts one sheet as usual when the reading range size notified from the reading unit 12 is less than the predetermined size. However, the billing counter 141 counts a plurality of sheets when the reading range size notified from the reading unit 12 is a predetermined size or more.

  The physical counter 142 counts one sheet as usual regardless of whether the reading range size notified from the reading unit 12 is less than the predetermined size or larger than the predetermined size.

  The printed sheet counter 15 is a functional unit that counts the number of sheets printed by the printing unit 13. The printing number counter 15 includes a billing counter 151 and a physical counter 152, thereby counting the number of printings by two types of methods.

  When the printing paper size notified from the printing unit 13 is less than the predetermined paper size, the billing counter 151 counts one sheet as usual. However, the billing counter 151 counts a plurality of sheets when the printing paper size notified from the printing unit 13 is equal to or larger than the predetermined paper size.

  The physical counter 152 counts one sheet as usual even when the printing paper size notified from the printing unit 13 is smaller than the predetermined paper size or larger than the predetermined paper size.

  The display unit 16 is a functional unit that allows the user to display the number of read sheets and the number of printed sheets. The display unit 16 displays the charge count result by displaying the charge counts by the charge counters 141 and 151. The display unit 16 displays the physical counts by the physical counters 142 and 152, thereby displaying the replacement time of consumables such as feed rollers.

{Counting process for the number of scanned and printed sheets}
Next, a flow of processing in which the digital multi-function peripheral 1 counts the number of read sheets and the number of printed sheets will be described. FIG. 2 is a flowchart showing the flow of count processing in the digital multi-function peripheral 1. The processing flow in the read number counter 14 and the printed number counter 15 is the same. Therefore, the flow of processing in the read number counter 14 will be described.

  The reading unit 12 receives a notification about setting contents from the setting unit 11. Then, when the reading unit 12 completes reading of one read original, the reading unit 12 notifies the read number counter 14 of the size of the read range in which the reading has been completed (step S1).

  First, a method in which the physical counter 142 counts the number of read sheets will be described. The physical counter 142 counts one sheet as usual regardless of the reading range size received from the reading unit 12 (step S2).

  Next, a method in which the billing counter 141 counts the number of read sheets will be described. When the reading range size received from the reading unit 12 is A3 size or larger (YES in step S3), billing counter 141 counts two sheets (step S4).

  When the reading range size received from the reading unit 12 is less than the A3 size (NO in step S3), the billing counter 141 counts one sheet as usual (step S5).

  When the reading unit 12 has finished executing the setting contents notified from the setting unit 11 (YES in step S6), the reading operation is terminated. In addition, the reading unit 12 finishes notifying the reading number counter 14 of the reading range size.

  When the setting content received from the setting unit 11 has not been executed (NO in step S6), the reading unit 12 continues the reading operation. Further, the reading unit 12 continues to notify the reading number counter 14 of the reading range size (step S1).

  FIG. 3 is a diagram illustrating a usage state and a count in the digital multi-function peripheral 1. 4 to 8 are diagrams showing reading processing and printing processing in the digital multi-function peripheral 1.

  In the left block of FIG. 3, the number of copies is described. In the central block of FIG. 3, the read original size, the print paper size, and the enlargement / reduction ratio in each copy are described. The right side block of FIG. 3 describes the charge count for the number of read sheets and the number of printed sheets for each copy. In each copy, there is one read document processed by the reading unit 12 and one print sheet processed by the printing unit 13. The size of the maximum reading range read by the reading unit 12 is A3 size because of the performance of the digital multi-function peripheral 1.

  In the first copy, an A4 size read original is copied on an A3 size printing paper at an equal magnification with an enlargement / reduction ratio of 100%. The reading process and the printing process in the first copy are shown in FIG.

  The size of the printing paper 131 is A3 size. The enlargement / reduction ratio is 100%. Therefore, the size of the reading range 121 is an A3 size obtained by dividing the size of the printing paper 131 by the enlargement / reduction ratio.

  The size of the reading range 121 is larger than the A4 size that is the size of the read document 120. Therefore, not only the area of the read original 120 but also the area of the reading range 121 is read by the reading unit 12 (step S1).

  Since the reading range size is A3 size, the charge count of the number of read sheets is 2 (YES in step S3, step S4). However, the physical count of the number of read sheets is 1 (step S2). Since the printing paper size is A3 size, the charge count of the number of printed sheets is 2 (YES in step S3, step S4). However, the physical count of the number of printed sheets is 1 (step S2).

  In the second copy, an A3 size read document is copied on an A4 size printing paper at an equal magnification with an enlargement / reduction ratio of 100%. The reading process and the printing process in the second copy are shown in FIG.

  The size of the printing paper 133 is A4 size. The enlargement / reduction ratio is 100%. Therefore, the size of the reading range 123 is an A4 size obtained by dividing the size of the printing paper 133 by the enlargement / reduction magnification.

  The size of the reading range 123 is smaller than the A3 size that is the size of the read document 122. Therefore, the entire area of the read original 122 is not read by the reading unit 12. The area of the reading range 123 is read by the reading unit 12 (step S1).

  Since the reading range size is A4 size, the charge count of the number of read sheets is 1 (NO in step S3, step S5). The physical count of the number of read sheets is 1 (step S2). Since the printing paper size is A4 size, the charge count of the number of printed sheets is 1 (NO in step S3, step S5). Further, the physical count of the number of printed sheets is 1 (step S2).

  In the third copy, an enlarged copy with an enlargement / reduction ratio of 115% is performed on an A3 size print sheet for an A3 size read original. The reading process and the printing process in the third copy are shown in FIG.

  The size of the printing paper 135 is A3 size. The enlargement / reduction ratio is 115%. Therefore, the size of the reading range 125 is a B4 size obtained by dividing the size of the printing paper 135 by the enlargement / reduction ratio.

  The size of the reading range 125 is smaller than the A3 size that is the size of the read document 124. Therefore, the entire area of the read original 124 is not read by the reading unit 12. The area of the reading range 125 is read by the reading unit 12.

  Since the reading range size is B4 size, the charge count of the number of read sheets is 1. Further, the physical count of the number of read sheets is 1. Since the printing paper size is A3 size, the charging count of the number of printed sheets is 2. However, the physical count of the number of printed sheets is 1.

  In the fourth copy, a reduced copy with an enlargement / reduction ratio of 86% is performed on a B4 size print sheet on a B4 size read original. The reading process and the printing process in the fourth copy are shown in FIG.

  The size of the printing paper 137 is B4 size. The enlargement / reduction ratio is 86%. Therefore, the size of the reading range 127 is an A3 size obtained by dividing the size of the printing paper 137 by the enlargement / reduction ratio.

  The size of the reading range 127 is larger than the B4 size that is the size of the read document 126. Therefore, not only the area of the read original 126 but also the area of the reading range 127 is read by the reading unit 12.

  Since the reading range size is A3 size, the charge count of the number of read sheets is 2. However, the physical count of the number of read sheets is 1. Since the printing paper size is B4 size, the charge count of the number of printed sheets is 1. The physical count of the number of printed sheets is 1.

  In the fifth copy, an A3 size read document is subjected to reduced copy with an enlargement / reduction ratio of 86% on A3 size printing paper. The reading process and the printing process in the fifth copy are shown in FIG.

  The size of the printing paper 139 is A3 size. The enlargement / reduction ratio is 86%. Therefore, the size of the reading range 129 is a size obtained by dividing the size of the printing paper 139 by the enlargement / reduction ratio. That is, the size of the reading range 129 is larger than the A3 size and is not a standard size.

  The size of the reading range 129 is larger than the A3 size that is the size of the maximum reading range read by the reading unit 12. For this reason, the reading unit 12 reads the area of the maximum reading range.

  Since the reading range size is A3 size, the charge count of the number of read sheets is 2. However, the physical count of the number of read sheets is 1. Since the printing paper size is A3 size, the charging count of the number of printed sheets is 2. However, the physical count of the number of printed sheets is 1.

  In the sixth copy, a reduced copy in which the enlargement / reduction ratio is automatically set is performed on the A4 size printing paper for the A3 size read document. The automatically set enlargement / reduction ratio is 70%. The reading range size is equal to the reading document size. Then, the reading range area is read by the reading unit 12.

  Since the reading range size is A3 size, the charge count of the number of read sheets is 2. However, the physical count of the number of read sheets is 1. Since the printing paper size is A4 size, the charge count of the number of printed sheets is 1. The physical count of the number of printed sheets is 1.

  In the seventh copy, an enlarged copy in which an enlargement / reduction ratio is automatically set is performed on an A3 size printing paper for an A4 size read original. The enlargement / reduction ratio automatically set is 141%. The reading range size is equal to the reading document size. Then, the reading range area is read by the reading unit 12.

  Since the reading range size is A4 size, the charge count of the number of read sheets is 1. Further, the physical count of the number of read sheets is 1. Since the printing paper size is A3 size, the charging count of the number of printed sheets is 2. However, the physical count of the number of printed sheets is 1.

  In the eighth copy, an enlarged copy with an enlargement / reduction ratio of 120% is performed on an A3 size print sheet for an A3 size read original. That is, when the eighth copy and the third copy described with reference to FIG. 6 are compared, the enlargement / reduction magnification is different.

  The printing paper size is A3 size. The enlargement / reduction ratio is 120%. Therefore, the reading range size is a size obtained by dividing the printing paper size by the enlargement / reduction ratio. That is, the reading range size is a size smaller than the B4 size and larger than the A4 size, and is not a standard size.

  The reading range size is smaller than the A3 size which is the reading document size. Therefore, the entire area of the read original is not read by the reading unit 12. The area of the reading range is read by the reading unit 12.

  The reading range size is not a standard size. At this time, billing counter 141 does not count billing based on the read range size. Rather, the charging counter 141 performs charging counting based on a fixed size that is larger than the reading range size and closest to the reading range size. That is, the accounting counter 141 performs accounting counting after regarding that the reading range size is B4 size.

  Since the reading range size is regarded as the B4 size, the charge count of the number of read sheets is 1. Further, the physical count of the number of read sheets is 1. Since the printing paper size is A3 size, the charging count of the number of printed sheets is 2. However, the physical count of the number of printed sheets is 1.

  In the ninth copy, a B4 size read document is subjected to a reduction copy with an enlargement / reduction ratio of 90% on a B4 size printing paper. That is, when the ninth copy and the fourth copy described with reference to FIG. 7 are compared, the enlargement / reduction ratios are different.

  The printing paper size is B4 size. The enlargement / reduction ratio is 90%. Therefore, the reading range size is a size obtained by dividing the printing paper size by the enlargement / reduction ratio. That is, the reading range size is a size that is smaller than the A3 size and larger than the B4 size, and is not a standard size.

  The reading range size is larger than the B4 size that is the reading document size. For this reason, the reading unit 12 reads not only the read document area but also the read range area.

  The reading range size is not a standard size. At this time, the billing counter 141 performs billing counting as in the eighth copy. That is, the accounting counter 141 performs accounting counting after regarding that the reading range size is A3 size.

  Since the reading range size is regarded as A3 size, the charging count of the number of read sheets is 2. However, the physical count of the number of read sheets is 1. Since the printing paper size is B4 size, the charge count of the number of printed sheets is 1. The physical count of the number of printed sheets is 1.

{Display screen of charge summary result and consumable replacement time}
Next, a description will be given of a method in which the digital multi-function peripheral 1 displays the charge summary result and the replacement time of consumables such as a feed roller. FIG. 9 is a diagram showing a screen for displaying the charge total result. FIG. 10 is a diagram showing a screen displaying the feed roller replacement time. The digital multi-function peripheral 1 may print a list that displays the charge summary results and the replacement time of consumables such as feed rollers in the printing unit 13.

  First, a screen for displaying the charge summary result will be described. The user operates the digital multi-function peripheral 1 so that the charge summary result is displayed on the display unit 16. The display screen 161 for displaying the charge total result shown in FIG. 9 includes a display area 162 for displaying the reading fee, a display area 163 for displaying the printing fee, a display area 164 for displaying the total fee of the reading fee and the printing fee, and the like. Composed.

  The number of read sheets displayed in the display area 162 is 14, which is the total of the charge count of the number of read sheets by the charge counter 141. That is, the digital multi-function peripheral 1 tallies the reading charges in consideration of the size of the reading range size. The accounting coefficient is a coefficient that determines a reading fee for one sheet. The charging coefficient displayed in the display area 162 is 2 yen for each read number. Therefore, the reading fee displayed in the display area 162 is 28 yen (= 14 sheets × 2 yen / 1 sheet).

  The number of printed sheets displayed in the display area 163 is 14, which is the total of the billing count of the number of printed sheets by the billing counter 151. That is, the digital multi-function peripheral 1 totals the printing charges in consideration of the size of the printing paper size. The charging coefficient is a coefficient that determines a printing fee for one printed sheet. The accounting coefficient displayed in the display area 163 is 5 yen per printed sheet. Therefore, the printing fee displayed in the display area 163 is 70 yen (= 14 sheets × 5 yen / 1 sheet).

  Based on the reading fee displayed in the display area 162 and the printing fee displayed in the display area 163, the total fee displayed in the display area 164 is tabulated as 98 yen (= 28 yen + 70 yen). The user may pay the usage fee to the administrator of the digital multi-function peripheral 1 based on the total fee displayed in the display area 164.

  Next, a screen for displaying the feed roller replacement time will be described. The user or the administrator operates the digital multifunction peripheral 1 so that the feed roller replacement time is displayed on the display unit 16. The display screen 165 for displaying the feed roller replacement time shown in FIG. 10 includes a display area 166 for displaying the feed roller replacement time for the reading unit 12, a display area 167 for displaying the feed roller replacement time for the printing unit 13, and the like. The

  The number of read sheets displayed in the display area 166 is 9, which is the total of the physical count of the number of read sheets by the physical counter 142. That is, the digital multi-function peripheral 1 determines whether or not the feeding roller of the reading unit 12 should be replaced without considering the size of the reading range. The replacement guide number is a guideline indicating how many read originals are delivered by the feed roller of the reading unit 12 and the feed roller of the reading unit 12 should be replaced.

  The reference number of replacements displayed in the display area 166 is 200 sheets. Therefore, the message “No exchange is necessary” is displayed in the display area 166. When the number of read sheets displayed in the display area 166 approaches 200, a warning “soon to replace” is displayed in the display area 166. The user or administrator may replace the feed roller of the reading unit 12 based on the warning displayed in the display area 166.

  The number of printed sheets displayed in the display area 167 is 9, which is the total of the physical count of the number of printed sheets by the physical counter 152. That is, the digital multi-function peripheral 1 determines whether or not the feed roller of the printing unit 13 should be replaced without considering the size of the printing paper. The reference number of replacements is a guideline indicating how many sheets of printing paper the delivery roller of the printing unit 13 delivers should be replaced.

  The reference number of replacements displayed in the display area 167 is 200 sheets. Therefore, a message “No exchange is necessary” is displayed in the display area 167. When the number of printed sheets displayed in the display area 167 approaches 200, a warning “soon to replace” is displayed in the display area 167. The user or administrator may replace the feed roller of the printing unit 13 based on the warning displayed in the display area 167.

  Finally, the effects of the present invention will be summarized. The digital multi-function peripheral 1 calculates the reading range size by dividing the printing paper size by the enlargement / reduction ratio. The digital multi-function peripheral 1 increases the charging count by the charging counter 141 when the reading range size is equal to or larger than the predetermined size than when the reading range size is less than the predetermined size. In addition, when the print paper size is equal to or larger than the predetermined paper size, the digital multifunction peripheral 1 increases the charge count by the charge counter 151 compared to when the print paper size is less than the predetermined paper size. Therefore, the digital multi-function peripheral 1 can calculate the usage fee in accordance with the usage situation in consideration of the reading range size and the printing paper size in the enlarged copy or reduced copy.

  The digital multi-function peripheral 1 determines whether or not a consumable item such as a feed roller of the reading unit 12 should be replaced based on the physical count by the physical counter 142. Further, the digital multi-function peripheral 1 determines whether consumables such as a feed roller of the printing unit 13 should be replaced based on the physical count by the physical counter 152. Therefore, the digital multi-function peripheral 1 can independently determine the replacement timing of consumables such as the feed roller of the reading unit 12 and the printing unit 13.

{Modification 1}
In the eighth and ninth copies described with reference to FIG. 3, the reading range size is not a standard size. In the above-described embodiment, the charging counter 141 performs charging counting based on a fixed size that is larger than the reading range size and closest to the reading range size. However, the charging counter 141 may perform charging counting based on a standard size that is smaller than the reading range size and closest to the reading range size.

  In the eighth copy, the reading range size is a size smaller than the B4 size and larger than the A4 size, and is not a standard size. In this modification, the accounting counter 141 performs accounting counting after assuming that the reading range size is A4 size. Therefore, as in the above-described embodiment, the charge count for the number of read sheets is 1.

  In the ninth copy, the reading range size is a size smaller than the A3 size and larger than the B4 size, and is not a standard size. In this modification, the accounting counter 141 performs accounting counting after regarding that the reading range size is B4 size. Therefore, unlike the above-described embodiment, the charge count for the number of read sheets is 1.

  In the present modification, the number of readings displayed in the display area 162 is smaller than the number of readings displayed in the display area 162 in the above-described embodiment. That is, the reading fee displayed in the display area 162 in the present modification is lower than the reading fee displayed in the display area 162 in the above-described embodiment. Therefore, the present modification is more effective when the reading fee is set lower than the above-described embodiment.

{Modification 2}
In the embodiment described above, the A3 size is set as the threshold value of the reading range size for determining whether the billing counter 141 counts two sheets or counts one sheet as usual. . However, a reading range size other than the A3 size may be set as the reading range size threshold. The printing paper size threshold value may be set in the same manner as the reading range size threshold value setting.

  A plurality of reading range size threshold values may be set as the reading range size threshold value. For example, when the reading range size is A3 size or larger, the count for three sheets is counted, when the reading range size is equal to or larger than A5 size and smaller than A3 size, the count for two sheets is counted, and when the reading range size is smaller than A5 size, 1 is counted. Counting of sheets may be performed. The printing paper size threshold value may be set in the same manner as the reading range size threshold value setting.
