[0004]
Since the conventional digital copying machine shown is capable of performing color printing, the developing unit 106 contains four color toners of CMYK (cyan, magenta, yellow, and black).
[0005]
Next, the operation of the above configuration will be described. Here, in order to simplify the description of the operation, a case of monochrome printing will be described as an example.
[0006]
When the user places a document on the contact glass 127 and presses a copy button (not shown) provided on the digital copying machine, a lamp (not shown) provided on the first carriage 104 is turned on to copy the document. Expose.
[0007]
Subsequently, the exposed light is reflected by the document, and the reflected light is guided to the CCD 116 via the second carriage 105 and the lens 115. Note that the first carriage 104 moves in the sub-scanning direction in order to be able to read all the originals placed on the contact glass 127.
[0008]
Subsequently, the reflected light that has reached the CCD 116 is photoelectrically converted to electrical digital data (image data). Image data obtained by photoelectric conversion is subjected to various image processing such as color correction processing, γ correction processing, MTF correction processing, and area separation processing, and is then converted again into light by the LD to emit light.
[0009]
The light emitted from the LD is guided through the respective devices of the polygon mirror 110, the Fθ lenses 111 and 112, the BTL lens 113, the writing mirror 107, and the dustproof glass 108, and exposes the photosensitive drum 109. The surface of the photosensitive drum 109 is charged in advance with a certain charge by the charging charger 114, and the charge is changed by exposure from the LD to form an electrostatic latent image.
[0010]
Here, the charge on the surface of the photosensitive drum 109 will be described. For example, the exposure is turned on for the portion where the toner is to be placed, and the charge on the surface of the photosensitive drum 109 is charged to + (plus). In this case, although + is charged here, it goes without saying that-(minus) charge may be used. An image electrically created by changing the charge on the surface of the photosensitive drum 109 in this manner is an electrostatic latent image.
[0011]
When the copying operation is started, the photosensitive drum 109 starts rotating in the direction of the arrow shown in FIG. 10, and when the portion charged to + by the exposure from the LD reaches the developing device 106, the photosensitive drum 109 is previously stored in the developing device 106. The toner (in this case, a negatively charged toner) that has been mounted and has a charge opposite to that of the exposed charge adheres to the exposed and charged portion by electrostatic force.
[0012]
When the photosensitive drum 109 further rotates and reaches the intermediate transfer belt 119, the intermediate transfer belt 119 is charged by the intermediate transfer charger 123 with + charge larger than the + charge charged on the photosensitive drum 109. Then, the toner (that is, toner image) adhered on the photosensitive drum 109 is transferred onto the intermediate transfer belt 119. The residual toner (toner that has not been completely transferred) is removed from the photosensitive drum 109 after the transfer by the drum cleaning unit 117 and is ready for the next printing operation.
[0013]
Subsequently, the recording paper onto which the toner image has been transferred is conveyed to a fixing unit including the fixing roller 103 and the pressure roller 102 by the conveyance belt 126, and high temperature and high pressure are applied by the fixing roller 103 and the pressure roller 102. Then, the toner image is fused to the recording sheet, and the sheet is ejected to complete one copy operation.
[0014]
In the case of color printing, since four colors of CMYK are required for printing, the scanner is read four times in accordance with the four colors of CMYK, and the developing device 106 and the toner are prepared for the four colors. The development of four colors is performed by rotating the 106 by 90 degrees for each color.
[0015]
In the case of color printing, the same operation as in the case of monochrome printing is performed four times on the photosensitive drum 109, and four colors of toner are applied on the intermediate transfer belt 119 to transfer the fourth color. After that, the image is transferred to a recording sheet to realize color printing. Therefore, the cleaning operation of the photosensitive drum 109 is performed for each color, and the cleaning operation of the intermediate transfer belt 119 is performed after the transfer of the recording paper after the transfer of the fourth color.
[0016]
Next, a method of counting the number of copy operations of the digital copying machine will be described. First, the counter of the digital copying machine will be described. The counter of the digital copying machine can be roughly classified into a counter indicating how many times the copying operation has been performed by one digital copying machine and a counter for restricting the copying operation to the user.
[0017]
First, the total number of copying operations performed by the digital copying machine includes a mechanical counter that is incremented at the end of printing and an electrical counter that is stored in NVRAM or the like. When the printing is restored and one printing operation is completed, the counter value is incremented by one. These applications are used for estimating the scheduled time of a periodic inspection by a serviceman based on the total number of counters, and for managing charging based on the counted value.
[0018]
Further, for the paper size, the count-up is performed twice for the copy operation. In the case of the color print operation, two counts are performed depending on the price of one print in the case of color print. In some cases, two methods are used: a method of counting up four times from, and a counter for monochrome printing and a counter for color printing. Further, the total counter includes a counter called a jam counter for counting the number of paper jams, which is mainly used by a service person to diagnose a machine failure.
[0019]
The processing of the total counter will be described with reference to FIG. FIG. 11 is a flowchart showing the processing of a conventional total counter. Note that FIG. 11 illustrates a method of counting up in the case of a color printing operation.
[0020]
First, the digital color copying machine determines whether the user sets full-color printing, that is, whether or not to perform full-color printing (S1101). If it is determined that the printing is not full-color printing, the digital color copying machine waits for a copy ready state (ready state). (S1102) When the preparation is completed, the total counter is incremented (S1103), and the process ends.
[0021]
On the other hand, if it is determined in step S1101 that full-color printing is to be performed, the process waits for the end of the document reading operation (S1104), and after completion, determines whether there is a full-color printing counter (S1105). If it is determined, the full-color printing counter is incremented (S1106). If it is not determined, the total counter is incremented by a preset frequency so as to count up (S1107), and the process ends.
[0022]
Next, a counter that limits the copy operation to the user will be described. Counters that limit the copying operation to the user include a key counter, a key card, and a coin rack. These counters all store how many copying machines each user has used and use the copying machine for the usage. This is used when charging a fee.
[0023]
Next, the flow of processing of the counter for limiting the copying operation to the user will be described with reference to the drawings. 12 to 14 are flowcharts showing a conventional counter process for restricting a user from performing a copy operation. First, the case of the key counter shown in FIG. 12 will be described.
[0024]
The digital copying machine waits until the key counter is entered (S1201). Subsequently, it is determined whether or not the original reading operation has been completed (S1202). After the operation is completed, it is determined whether or not the copy is full-color printing (S1203). The key counter is incremented by the value of (S1204). If the printing is not full-color printing, the key counter is incremented (S1205), and the process is terminated.
[0025]
Next, the case of the key card shown in FIG. 13 will be described. The digital color copying machine waits until a key card is inserted (S1301). Subsequently, it is determined whether or not the original reading operation has been completed (S1302). After the completion, it is determined whether or not the copy is full-color printing (S1303). The key card is incremented by the value (S1304). If the printing is not full color printing, the key card is incremented (S1305), and the process is terminated.
[0026]
Next, the case of the coin rack shown in FIG. 14 will be described. The digital color copier determines whether or not the fee deposited in the coin rack is sufficient (S1401). If it is determined that the fee is not sufficient, the digital color copier uses a display unit (not shown) provided in the digital color copier. An alert process is performed (S1402), and the process returns to step S1401.
[0027]
On the other hand, if it is determined in step S1401 that the fee is sufficient, it is determined whether the original reading operation has been completed (S1403). After the operation is completed, it is determined whether the copy is full-color printing (S1404). In the case of full-color printing, a preset charge value for full-color printing is decremented from the display of the coin rack (S1405), and if not, the charge value for monochrome printing is decremented from the display of the coin rack (S1406). , End the process.
[0028]
Next, the facsimile function of the digital copying machine will be described. First, a description will be given, with reference to FIG. 15, of the processing of the counter and the management of charging when the facsimile function is performed. FIG. 15 is a block diagram showing a control unit of a conventional digital copying machine.
[0029]
A conventional digital copying machine includes a CPU 201 for controlling the digital copying machine, a ROM 202 for storing a control program and the like performed by the CPU 201, a RAM 203 for storing values and image data set by a user, and a color correction process. , .Gamma. Correction processing, MTF correction processing, area separation processing, etc., an image processing circuit 204, and a FontROM 205 storing fonts corresponding to data sent from a connected computer (not shown). And an encoding / decoding circuit 206 for performing encoding or decoding for facsimile transmission and reception of various data, and a facsimile for connecting various data which are connected or connected to a public line and encoded or decoded by the encoding / decoding circuit 206. MODEM 207 for transmission / reception, developing unit 106, photosensitive drum 109, LD, polygon An electrophotographic engine 208 and the like over 110, and an engine interface (engine I / F) 209 Metropolitan an interface for an electrophotographic engine 208.
[0030]
Next, the operation of the above configuration will be described. First, when facsimile transmission is performed, an image is read by the scanner unit 150 shown in FIG. 10, converted into a digital signal by the CCD 116, and then encoded according to the level (G3, G4, etc.) of the receiving party. The encoding / decoding circuit 206 performs encoding of MH, MMH, and the like, and performs transmission according to a protocol determined for a public line or a dedicated line via the MODEM 207 as shown in the block diagram of FIG. At this time, since no printing is performed by the digital copying machine, all the counters do not perform the increment as described above.
[0031]
The above operation will be described with reference to FIG. FIG. 16 is a flowchart showing facsimile transmission in a conventional digital copying machine. First, the CPU 201 dials the telephone number designated by the user via the operation unit (not shown) (S1601), and waits for connection with the other party (S1602).
[0032]
Subsequently, after being connected to the other party, the image (data) read by the scanner unit 150 is encoded by the encoding / decoding circuit 206 such as MH and MMH (S1603), and is transmitted by facsimile (S1604).
[0033]
Subsequently, the CPU 201 determines whether or not there is a next document (S1605). If it is determined that there is, the scanner unit 150 reads the document again (S1606), and returns to step S1603. The process ends.
[0034]
When a facsimile is received by the facsimile function, it is determined whether or not the electrophotographic engine 208 of the digital copying machine is currently being used for a copying operation from another user at the time of receiving data from a transmission partner. If the ready state is determined, that is, if it is determined that the data can be used, decoding is performed by the encoding / decoding circuit 206 according to a procedure reverse to that of facsimile transmission, and the data is converted back to bitmap image data. Perform printing. At this time, when the printing operation is completed without an error such as a paper jam, the value of each counter is incremented and the process is terminated.
[0035]
If the electrophotographic engine 208 of the digital copier is busy when the received data is received, that is, it is determined that the data cannot be used, and if there is an alternative reception method such as memory reception, the memory prepared in advance is used. (The RAM 203) is temporarily stored and then printed. If there is no alternative receiving method, the facsimile transmission partner is set to a standby state (wait), and the electrophotographic engine 208 of the digital copying machine enters a ready state. Before printing.
[0036]
The above operation will be described with reference to FIG. FIG. 17 is a flowchart showing facsimile reception in a conventional digital copying machine. In FIG. 17, the processing is shown assuming that the alternative reception is performed by the RAM 203. First, when facsimile reception occurs (S1701), the CPU 201 determines whether the electrophotographic engine 208 is in a ready state (S1702).
[0037]
Subsequently, if it is determined in step S1702 that the electrophotographic engine 208 is in the ready state, facsimile reception is performed (S1703), and the received facsimile data is decoded by the encoding / decoding circuit 206 (S1704). The decrypted image data is printed by the electrophotographic engine 208 (S1705).
[0038]
Subsequently, after printing, the counter is incremented (S1706), and it is determined whether or not facsimile data of the next page is present (S1707). If so, the process ends.
[0039]
On the other hand, if it is determined in step S1702 that the electrophotographic engine 208 is not in the ready state, reception (memory reception) is performed in the RAM 203 as alternative reception (S1708), and the process waits until the electrophotographic engine 208 becomes ready (S1709). When the ready state is entered, the facsimile data stored in the RAM 203 (substitute reception) is decoded by the encoding / decoding circuit 206 (S1710), and the decoded image data is printed by the electrophotographic engine 208 (S1711). .
[0040]
Subsequently, after printing is performed, the counter is incremented (S1712), and it is determined whether or not there is facsimile data of the next page (S1713). If so, the process ends.
[0041]
[Problems to be solved by the invention]
However, according to the conventional accounting management using a key counter, a key card, a coin rack, and the like of a digital copying machine, it only counts the copying operation of the digital copying machine. It is used to count the number of times it has been used, and is incremented once at the time the copy operation is performed. Therefore, it is possible to manage the charge for the copy operation by the introducing company or organization. However, there is a problem that charging management for the public line usage fee when performing the facsimile function cannot be performed.
[0042]
In addition, companies that provide copy services, such as convenience stores, can only manage charges for the copying operation of digital copiers, so even if they have a facsimile function, they cannot be used by customers, There is a problem that the facsimile function of the copying machine cannot be introduced.
[0043]
The present invention has been made in view of the above, and an object of the present invention is to enable not only a copy function but also a facsimile function to perform charge management.

[0054]
Since the digital copying machine according to the first embodiment is capable of performing color printing, the developing device 106 contains four color toners of CMYK (cyan, magenta, yellow, and black).
[0055]
Next, the basic operation of the above configuration will be described. To simplify the description of the basic operation, a case of monochrome printing will be described as an example.
[0056]
When the user places a document on the contact glass 127 and presses a copy button (not shown) provided on the digital copying machine, a lamp (not shown) provided on the first carriage 104 is turned on to copy the document. Expose.
[0057]
Subsequently, the exposed light is reflected by the document, and the reflected light is guided to the CCD 116 via the second carriage 105 and the lens 115. Note that the first carriage 104 moves in the sub-scanning direction in order to be able to read all the originals placed on the contact glass 127.
[0058]
Subsequently, the reflected light that has reached the CCD 116 is photoelectrically converted to electrical digital data (image data). Image data obtained by photoelectric conversion is subjected to various image processing such as color correction processing, γ correction processing, MTF correction processing, and area separation processing, and is then converted again into light by the LD to emit light.
[0059]
The light emitted from the LD is guided through the respective devices of the polygon mirror 110, the Fθ lenses 111 and 112, the BTL lens 113, the writing mirror 107, and the dustproof glass 108, and exposes the photosensitive drum 109. The surface of the photosensitive drum 109 is charged in advance with a certain charge by the charging charger 114, and the charge is changed by exposure from the LD to form an electrostatic latent image.
[0060]
Here, the charge on the surface of the photosensitive drum 109 will be described. For example, the exposure is turned on for the portion where the toner is to be placed, and the charge on the surface of the photosensitive drum 109 is charged to + (plus). In this case, although + is charged here, it goes without saying that-(minus) charge may be used. An image electrically created by changing the charge on the surface of the photosensitive drum 109 in this manner is an electrostatic latent image.
[0061]
When the copying operation is started, the photosensitive drum 109 starts rotating in the direction of the arrow shown in FIG. 10, and when the portion charged to + by the exposure from the LD reaches the developing device 106, the photosensitive drum 109 is previously stored in the developing device 106. The toner (in this case, a negatively charged toner) that has been mounted and has a charge opposite to that of the exposed charge adheres to the exposed and charged portion by electrostatic force.
[0062]
When the photosensitive drum 109 further rotates and reaches the intermediate transfer belt 119, the intermediate transfer belt 119 is charged by the intermediate transfer charger 123 with + charge larger than the + charge charged on the photosensitive drum 109. Then, the toner (that is, toner image) adhered on the photosensitive drum 109 is transferred onto the intermediate transfer belt 119. The residual toner (toner that has not been completely transferred) is removed from the photosensitive drum 109 after the transfer by the drum cleaning unit 117 and is ready for the next printing operation.
[0063]
Subsequently, the recording paper onto which the toner image has been transferred is conveyed to a fixing unit including the fixing roller 103 and the pressure roller 102 by the conveyance belt 126, and high temperature and high pressure are applied by the fixing roller 103 and the pressure roller 102. Then, the toner image is fused to the recording sheet, and the sheet is ejected to complete one copy operation.
[0064]
In the case of color printing, since four colors of CMYK are required for printing, the scanner is read four times in accordance with the four colors of CMYK, and the developing device 106 and the toner are prepared for the four colors. The development of four colors is performed by rotating the 106 by 90 degrees for each color.
[0065]
In the case of color printing, the same operation as in the case of monochrome printing is performed four times on the photosensitive drum 109, and four colors of toner are applied on the intermediate transfer belt 119 to transfer the fourth color. After that, the image is transferred to a recording sheet to realize color printing. Therefore, the cleaning operation of the photosensitive drum 109 is performed for each color, and the cleaning operation of the intermediate transfer belt 119 is performed after the transfer of the recording paper after the transfer of the fourth color.
[0066]
Next, a description will be given of a charging management method for a copying operation in the digital copying machine according to the first embodiment. FIG. 2 is a block diagram illustrating a control unit of the digital copying machine according to the first embodiment. The digital copying machine according to the first embodiment includes a CPU 201 that controls the digital copying machine, a ROM 202 that stores a control program and the like performed by the CPU 201, a RAM 203 that stores values set by a user, image data, and the like.

The facsimile charging table storage unit 210 plays the role of the facsimile charging table storage unit of the present invention, and the charging counter 211 plays the role of the charging management unit of the present invention.
[0068]
Next, control relating to a copy operation in the above configuration will be described. In the control relating to the copy operation, the frequency of the accounting counter 211 is increased by a preset frequency (3 in the first embodiment) for one copy operation. As a process of increasing the frequency of the charging counter 211, a sensor (not shown) is used for a portion where the recording paper is conveyed by the paper feed cassette 101, the registration roller 121, the conveyance belt 126, and the fixing roller 103 shown in FIG. The CPU 201 determines whether the attached recording paper is passing for a predetermined time set in advance, and as a result of the determination, if the recording paper is passing for a predetermined time, the frequency of the charging counter 211 is increased. .
[0069]
Also, if the recording paper is not conveyed even after the preset specified time, or if it is determined that the recording paper is present beyond the specified time, that is, if it is determined that a paper jam has occurred on the recording paper Then, the operation of the electrophotographic engine 208 is stopped, an alert process is performed to indicate that a paper jam has occurred, and at the same time, a jam counter (not shown) provided in advance at each location where the paper jam has occurred is incremented by one.
[0070]
The jam counter and a total counter (not shown) provided in advance are stored in a configuration as shown in FIG. FIG. 3 is an explanatory diagram showing a configuration in which the jam counter and the total counter store. Although the electronic counter is used as the counter in the first embodiment, it is possible to use a mechanical counter that counts with a driving force based on the operation of the copying function at the same time as the operation of the copying function is performed. Of course.
[0071]
Next, the processing of the accounting counter 211 when performing the facsimile function will be described. First, when facsimile transmission is performed, an image is read by the scanner unit 150 shown in FIG. 1, converted into a digital signal by the CCD 116, and then encoded according to the level (G3, G4, etc.) of the receiving party. The coding / decoding circuit 206 performs coding of MH, MMH, etc., and performs transmission according to a protocol determined by a public line via the MODEM 207 as shown in the block diagram of FIG.
[0072]
Next, in the case of facsimile reception, it is determined whether or not the electrophotographic engine 208 of the digital copying machine is currently being used by a copying operation from another user when receiving data comes from a transmission partner. As a result of the determination, if the electrophotographic engine 208 is not currently used, that is, if the electrophotographic engine 208 is in a ready state, the received data is decoded by the encoding / decoding circuit 206 according to a procedure reverse to that of facsimile transmission. Further, the data is converted into bitmap image data and printed. As for the charge for the printed operation, the frequency of the charge counter 211 is increased three times as in the case of the copy function.
[0073]
Also, when the electrophotographic engine 208 of the digital copying machine is in a busy state, that is, when it is determined that the data cannot be used when there is received data, and when there is an alternative reception method such as memory reception, a memory prepared in advance is used. In the first embodiment, the data is temporarily stored in the RAM 203) and then printed. If there is no alternative receiving method, the facsimile transmission partner is set to a standby state (wait), and the electrophotographic engine 208 of the digital copying machine is ready. Printing is performed after the state.
[0074]
Next, charging processing when the facsimile function of the first embodiment is used will be described. First, the CPU 201 determines whether facsimile transmission or facsimile reception is performed, and as a result of the determination by the CPU 201, when facsimile reception is performed, a fee is charged based on permission for use in a collect call, and otherwise, , Do not charge.
[0075]
In order to charge when using the facsimile function, the clock function provided inside the digital copying machine is operated at the same time when the communication line is connected via the MODEM 207, and the time when the line is cut off is checked. Measure the time involved. The measured time is set in a table as shown in FIG. 4 in advance as a charging target table stored in the facsimile charging table storage unit 210, the time obtained by the clock function, and the communication destination The public line usage fee is calculated based on which station number corresponds to which area. FIG. 4 is an explanatory diagram showing table data to be charged which is stored in the facsimile charging table storage unit 210.
[0076]
In the charge management of the digital copying machine, the charge data for the copy operation is set in advance to a fixed charge for one copy operation, while the charge data for the facsimile function (that is, the public line In general, the fee is charged in units of 10 yen in Japan, so table data is prepared in the facsimile charging table storage unit 210 as shown in FIG. .
[0077]
After calculating the public line usage fee, the frequency of the charging counter 211 is increased by the public line usage fee (10 yen = two times in the first embodiment). In the first embodiment, the frequency of the billing counter 211 is set to 5 yen and one charge performed by the copying function is set to 15 yen. However, other values may be used. Is, of course.
[0078]
As described above, according to the first embodiment, the frequency of the charging counter 211 is increased each time the copying function is performed, and the frequency of the charging counter 211 is also increased when facsimile transmission / reception is performed using the facsimile charging table storage unit 210. First, since the charge management is performed based on the frequency of the charge counter 211, the charge management can also be performed for the facsimile function of the digital copying machine.
[0079]
[Embodiment 2]
In the second embodiment, the description will be made assuming that the charging counter 211 is replaced with the NVRAM 501. The second embodiment is basically the same as the first embodiment, and therefore only different points will be described with reference to the drawings.
[0080]
FIG. 5 is a block diagram showing a control unit of the digital copying machine according to the second embodiment. The digital copying machine according to the second embodiment includes a CPU 201 that controls the digital copying machine, a ROM 202 that stores a control program and the like performed by the CPU 201, a RAM 203 that stores values set by a user, image data, and the like. An image processing circuit 204 that performs various types of image processing such as color correction processing, γ correction processing, MTF correction processing, and area separation processing, and stores fonts corresponding to data sent from a connected computer (not shown). FontROM 205, an encoding / decoding circuit 206 for performing encoding or decoding for facsimile transmission / reception of various data, and various types of encoding / decoding performed by the encoding / decoding circuit 206 connected to a public line. MODEM 207 for facsimile data transmission / reception, developing unit 106, photosensitive drum 109, LD, A facsimile billing table storage for storing table data to be charged when facsimile transmission / reception is performed, with an electrophotographic engine 208 including a GON mirror 110 and an engine I / F 209 which is an interface for the electrophotographic engine 208; A unit 210, an NVRAM 501 for storing the fee charged and the department used in advance when the copying function and the facsimile function are performed, and a timer 502 for measuring the time during which facsimile transmission / reception is used. .
[0081]
Note that the NVRAM 501 plays a role of a department charge management unit of the present invention.
[0082]
The operation of the above configuration will be described. When the copying function is used, the copying operation is performed in the same manner as in the first embodiment, and no trouble such as paper jam occurs. The charge at the time of copying by multiplying by the number of sheets and the department used further are stored in the NVRAM 501 together.
[0083]
Next, charging when the facsimile function is used will be described. At the time of facsimile transmission, an image is read by the scanner unit 150 shown in FIG. 1, converted into a digital signal by the CCD 116, and then encoded / decoded according to the level (G3, G4, etc.) of the receiving party. The data is encoded by the circuit 206 and temporarily stored in the RAM 203.
[0084]
At the same time as the processing, the CPU 201 performs a process of dialing the telephone number input by the user and connecting to the destination of facsimile transmission, and at the time of connection with the destination of facsimile transmission, the level is determined by the level of the receiving partner. According to the protocol, the facsimile data stored in the RAM 203 is output to the other party via the MODEM 207 and the public line.
[0085]
Further, the CPU 201 starts the timer 502 at the same time as the connection to the public line. When all the facsimile data in the RAM 203 is output to the other party, the communication is terminated, the line is disconnected, and the timer 502 is stopped at the same time. In the second embodiment, the timer 502 is used to measure the charging of the facsimile function. However, similarly to the first embodiment, the timer provided in the digital copying machine can be used without using the timer 502. It goes without saying that the measurement for the facsimile function charge may be performed using the function.
[0086]
When the timer 502 stops, the CPU 201 refers to the table data stored in the facsimile billing table storage unit 210 from the station number of the telephone number input by the user and the time measured by the timer 502, and uses the facsimile function. The used public line charge is calculated, and the public line charge is stored in the NVRAM 501 together with the department used.
[0087]
At this time, the NVRAM 501 is configured as table data as shown in FIG. 6, and records the name of each department registered in advance by the user and the public line usage fee for facsimile use used in that department. Have been. FIG. 6 is an explanatory diagram showing the contents stored in the NVRAM 501. Also, the NVRAM 501 can clear the amount of money to 0 according to the user's designation, and can be used when monthly charge management is performed.
[0088]
Next, in the case of facsimile reception, when a notification of facsimile reception is notified via a public line, image data is received via the MODEM 207, and decoding is performed by the encoding / decoding circuit 206. After being converted to a bitmap image, it is temporarily stored in the RAM 203. Subsequently, when one page of image data is stored in the RAM 203, the CPU 201 determines whether or not the electrophotographic engine 208 is in use by another user's operation. The image data is output to the electrophotographic engine 208 via the engine I / F 209, and printing is performed by the electrophotographic method. Note that the charge for the printed operation is stored in the NVRAM 501 as in the case of the above-described copy function.
[0089]
When receiving a facsimile, if the receiving side, such as a collect call, pays the communication line usage fee, the timer 502 is started at the same time as the transmission when the facsimile reception starts, and the facsimile reception is terminated and the line is terminated. At the time of disconnection, the timer 502 is stopped and the time for using the line is measured. The measured time is stored in the NVRAM 501 together with the department that calculated and used the public line usage fee with reference to the table data stored in the facsimile charging table storage unit 210 as in the transmission. At this time, if there is no particular designation from the user, the information is stored as used by a predetermined default department.
[0090]
As described above, according to the second embodiment, the charge used when the copying function and the facsimile function are used is stored in the NVRAM 501 together with the department that used the billing function. In addition to the management of the number of prints only for the operation, the charge management of the public line usage fee used by the facsimile function can be performed, and the management of departments such as departments and sections can be performed.
[0091]
[Embodiment 3]
In the third embodiment, the description will be made on the assumption that the charge management of the copying function and the facsimile function of the digital copying machine are separately performed. Since the third embodiment is basically the same as the first embodiment, only different points will be described with reference to the drawings.
[0092]
FIG. 7 is a block diagram illustrating a control unit of the digital copying machine according to the third embodiment. The digital copying machine according to the third embodiment includes a CPU 201 that controls the digital copying machine, a ROM 202 that stores a control program and the like performed by the CPU 201, a RAM 203 that stores values set by a user, image data, and the like. An image processing circuit 204 that performs various types of image processing such as color correction processing, γ correction processing, MTF correction processing, and area separation processing, and stores fonts corresponding to data sent from a connected computer (not shown). FontROM 205, an encoding / decoding circuit 206 for performing encoding or decoding for facsimile transmission / reception of various data, and various types of encoding / decoding performed by the encoding / decoding circuit 206 connected to a public line. MODEM 207 for facsimile data transmission / reception, developing unit 106, photosensitive drum 109, LD, A facsimile billing table storage for storing table data to be charged when facsimile transmission / reception is performed, with an electrophotographic engine 208 including a GON mirror 110 and an engine I / F 209 which is an interface for the electrophotographic engine 208; A copy / print function counter 701 that counts a preset number of charges when performing a copy function and a print function; and a facsimile counter 702 that counts a preset number of charges when a facsimile function is performed. It is composed of
[0093]
The copy print function counter 701 plays the role of the copy print function counting means of the present invention, and the facsimile counter 702 plays the role of the facsimile function count means of the present invention.
[0094]
Next, control relating to a copy operation in the above configuration will be described. In the control relating to the copy operation, the frequency of the copy / print function counter 701 is increased by a preset frequency (three in the third embodiment) for one copy operation. As in the first embodiment, the process of increasing the frequency of the copy / print function counter 701 includes a portion where the recording paper is conveyed by the paper feed cassette 101, the registration roller 121, the conveyance belt 126, and the fixing roller 103 shown in FIG. A sensor (not shown) is attached to the CPU 201, and the CPU 201 determines whether or not the fed recording paper has passed for a predetermined time, and as a result of the determination, the recording paper has passed for a predetermined time. If so, the frequency of the copy / print function counter 701 is increased.
[0095]
Next, processing for performing the facsimile function will be described. First, when facsimile transmission is performed, an image is read by the scanner unit 150 shown in FIG. 1, converted into a digital signal by the CCD 116, and then encoded according to the level (G3, G4, etc.) of the receiving party. The decoding of the MH, MMH, and the like is performed by the / decoding circuit 206, and transmission is performed via the MODEM 207 according to the protocol determined for the public line or the dedicated line as shown in the block diagram of FIG.
[0096]
Next, in the case of facsimile reception, it is determined whether or not the electrophotographic engine 208 of the digital copying machine is currently being used by a copying operation from another user when receiving data comes from a transmission partner. As a result of the determination, if the electrophotographic engine 208 is not currently used, that is, if the electrophotographic engine 208 is in a ready state, the received data is decoded by the encoding / decoding circuit 206 according to a procedure reverse to that of facsimile transmission. Further, the data is converted into bitmap image data and printed. The charge for the printed operation increases the frequency of the copy / print function counter 701 as in the case of the copy function.
[0097]
If the electrophotographic engine 208 of the digital copying machine is busy when the received data is present, that is, if it is determined that the data cannot be used, and if there is an alternative receiving method such as memory receiving, a memory (RAM 203) prepared in advance is used. ) Is stored and then printed, and if there is no alternative receiving method, the facsimile transmission partner is put into a standby state (wait), and the digital photocopier's electrophotographic engine 208 becomes ready. Perform printing.
[0098]
Next, charging processing when the facsimile function of the third embodiment is used will be described. First, the CPU 201 determines whether or not to charge for facsimile, and if it is determined to be performed, subsequently, determines whether to transmit or receive facsimile. As a result of the determination by the CPU 201, when receiving a facsimile, a fee is charged for permitting use in a collect call, and otherwise, no fee is charged.
[0099]
In order to charge when using the facsimile function, the clock function provided inside the digital copying machine is operated at the same time when the communication line is connected via the MODEM 207, and the time when the line is cut off is checked. Measure the time involved. The measured time is set in advance to the table data to be charged in the facsimile charging table storage unit 210 as shown in FIG. 4, and the time obtained by the clock function and the communication destination are determined. The public line usage fee is calculated based on which station number corresponds to the area.
[0100]
After calculating the public line charge, the frequency of the facsimile counter 702 is increased by the public line charge (in the third embodiment, 10 yen = 2 times). In the third embodiment, the frequency of the copy / print function counter 701 and the facsimile counter 702 is set to 5 yen per time, and the charge for one time performed by the copy function is set to 15 yen. Of course, it may be.
[0101]
As described above, according to the third embodiment, since the copy print function counter 701 is provided for charging the copy function and the facsimile counter 702 is provided for charging the facsimile function, the charge for the copy function or the facsimile function is provided. Can be individually issued, so that billing management can be performed more easily and more accurately than in the first and second embodiments.
[0102]
Further, when the copy print function counter 701 and the facsimile counter 702 are configured so as to be able to perform charge management in a plurality of groups such as departments, one digital copying machine is shared and used by a plurality of departments. Accurate billing can be performed at times.
[0103]
[Embodiment 4]
In the fourth embodiment, a description will be given assuming that the printing function used in the digital copying machine is color, and when the copying function and the facsimile function are used, printing is performed in color. Since the fourth embodiment is basically the same as the second embodiment, only different points will be described with reference to the drawings.
[0104]
First, the concept of charge management for color printing used in the fourth embodiment will be described. If the digital copier used can perform color printing, charging, exposure, development, and cleaning of the transfer drum related to the electrophotographic method must be performed four times each, and accordingly, developing materials, toner, etc. Since the consumables of each color need four colors, they are more expensive than monochrome printing. Therefore, if the same charge is set for the monochrome printing operation, accurate charging cannot be performed. Therefore, in the fourth embodiment, the contents stored in the NVRAM 501 correspond to color printing.
[0105]
In the operation of the digital copier for color printing, mono-color printing (R (red), G (green), B (blue), C (cyan), M (magenta), Y (yellow), K (black) Normally, single-color printing) and full-color printing have different charges for one copy operation. Therefore, as shown in FIG. The unit price and the unit price for one full-color print are stored. If monocolor printing is performed by the user's operation, normal color electrophotographic printing is performed, and at the same time, the charge related to the copying operation is performed. Is added to the total charge of the charging department from the table data of the monochrome printing shown in FIG. 8 and stored in the NVRAM 501. FIG. 8 is an explanatory diagram showing the contents stored in the NVRAM 501. Also, the NVRAM 501 can clear the amount of money to 0 according to the user's designation, and can be used when monthly charge management is performed.
[0106]
At the same time, the total count of mono-color printing is added for the number of copies, and this value is separately used by a field service person or the like as a reference value for maintenance or the like. In the case of full-color printing, as in the case of mono-color printing, the charge is added using the charge of full-color printing in FIG. 8, and the value of the total number of full-color prints is added. Remember.
[0107]
Next, the charge management when the facsimile function is performed is measured by the timer 502 in the same manner as in the second embodiment irrespective of mono-color or full-color because the electronic photograph engine is not used for transmission. The public line usage fee is calculated based on the time and the table stored in the facsimile charging table storage unit 210, added to the value of the corresponding department in the NVRAM 501, and stored in the NVRAM 501.
[0108]
Next, since a communication fee is not charged when a mono-color print facsimile is received, if a mono-color print is received, only the charge per mono-color print shown in FIG. If it is added and received in full-color printing, only the fee per full-color printing shown in FIG. 8 is added to the corresponding department.
[0109]
As described above, according to the fourth embodiment, based on the table data stored in the NVRAM 501, in either case of mono-color printing or full-color printing, accounting corresponding to each is performed. In addition, even a digital copying machine that supports color printing can easily manage the charge.
[0110]
Furthermore, since the total number of mono-color printing and full-color printing is also stored in the NVRAM 501, for example, a field service person or the like can use it as a reference value for maintenance and the like, and the maintenance of the digital copying machine can be easily performed. Can be.
[0111]
[Embodiment 5]
In the fifth embodiment, a description will be given assuming that charging for monochrome printing and color printing is performed separately when the digital copying machine supports color printing. Since the fifth embodiment is basically the same as the fourth embodiment, only different points will be described with reference to the drawings.
[0112]
FIG. 9 is a block diagram showing a control unit of the digital copying machine according to the fifth embodiment. The digital copying machine according to the fifth embodiment includes a CPU 201 that controls the digital copying machine, a ROM 202 that stores a control program and the like performed by the CPU 201, a RAM 203 that stores values set by a user, image data, and the like. An image processing circuit 204 that performs various types of image processing such as color correction processing, γ correction processing, MTF correction processing, and area separation processing, and stores fonts corresponding to data sent from a connected computer (not shown). FontROM 205, an encoding / decoding circuit 206 for performing encoding or decoding for facsimile transmission / reception of various data, and various types of encoding / decoding performed by the encoding / decoding circuit 206 connected to a public line. MODEM 207 for facsimile data transmission / reception, developing unit 106, photosensitive drum 109, LD, An electrophotographic engine 208 including the Gonmirror 110 and the like, an engine interface (engine I / F) 209 as an interface for the electrophotographic engine 208, and table data to be charged when facsimile transmission / reception is performed. Facsimile charging table storage unit 210, a monochrome charging counter 901 that counts a preset frequency when using monochrome printing with the copy function, and a preset when using color printing, And a color charging counter 902 that counts the number of times that the data has been collected.
[0113]
The monochrome charge counter 901 plays the role of the first charge management means of the present invention, and the color charge counter 902 plays the role of the second charge management means of the present invention.
[0114]
Next, control relating to a copy operation in the above configuration will be described. The control related to the copy operation first determines whether the copy operation is designated for color printing or monochrome printing. In the case of color printing, the frequency of the color charging counter 902 is set to a preset frequency (implementation) for one copy operation. In the fifth embodiment, the number is 25). In the case of monochrome printing, as in the case of color printing, the frequency of the monochrome charging counter 901 is increased by a preset frequency (7 in the fifth embodiment) for one copy operation.
[0115]
As in the first embodiment, the processing for increasing the frequency of the monochrome charging counter 901 and the color charging counter 902 is performed by using the sheet cassette 101, the registration roller 121, the conveyance belt 126, and the fixing roller 103 shown in FIG. A sensor (not shown) is attached to a portion to be conveyed, and the CPU 201 determines whether or not the fed recording paper has passed for a predetermined time set in advance. In the case of passing, the frequency of the monochrome charging counter 901 and the color charging counter 902 are increased.
[0116]
Next, processing for performing the facsimile function will be described. First, when facsimile transmission is performed, an image is read by the scanner unit 150 shown in FIG. 1, converted into a digital signal by the CCD 116, and then encoded according to the level (G3, G4, etc.) of the receiving party. The coding / decoding circuit 206 performs coding of MH, MMH, and the like, and performs transmission according to a protocol determined for a public line or a dedicated line via the MODEM 207 as shown in the block diagram of FIG.
[0117]
Next, in the case of facsimile reception, it is determined whether or not the electrophotographic engine 208 of the digital copying machine is currently being used by a copying operation from another user when the reception data comes from the transmission partner. As a result of the determination, if the electrophotographic engine 208 is not currently used, that is, if the electrophotographic engine 208 is in a ready state, the received data is decoded by the encoding / decoding circuit 206 according to a procedure reverse to that of facsimile transmission. Further, the data is converted into bitmap image data and printed. The charge for the printed operation is determined in the same manner as in the case of the copy function by determining whether the copy operation is designated for color printing or monochrome printing. In the case of color printing, the frequency of the color charging counter 902 is determined. In this case, the frequency of the monochrome charging counter 901 is increased.
[0118]
If the electrophotographic engine 208 of the digital copying machine is busy when the received data is present, that is, if it is determined that the data cannot be used, and if there is an alternative receiving method such as memory receiving, a memory (RAM 203) prepared in advance is used. ) Is stored and then printed, and if there is no alternative receiving method, the facsimile transmission partner is put into a standby state (wait), and the digital photocopier's electrophotographic engine 208 becomes ready. Perform printing.
[0119]
Next, charging processing when the facsimile function of the fifth embodiment is used will be described. First, the CPU 201 determines whether or not to charge for facsimile, and if it is determined to be performed, subsequently, determines whether to transmit or receive facsimile. As a result of the determination by the CPU 201, when receiving a facsimile, a fee is charged for permitting use in a collect call, and otherwise, no fee is charged.
[0120]
In order to charge when using the facsimile function, the clock function provided inside the digital copying machine is operated at the same time when the communication line is connected via the MODEM 207, and the time when the line is cut off is checked. Measure the time involved. For the measured time, the table data to be charged in the facsimile charging table storage unit 210 is set in advance, and the time obtained by measuring with the clock function and the station number to which the other party communicated correspond to Based on, calculate the public line usage fee.
[0121]
After calculating the public line charge, the frequency of the monochrome charging counter 901 is increased by the public line charge (10 yen = 10 frequencies in the fifth embodiment). In the fifth embodiment, the frequency of the monochrome charging counter 901 and the color charging counter 902 is set to 1 yen = 1 yen, one charge for the monochrome printing copy operation is set to 7 yen, and furthermore, the color printing is performed. In the above description, one charge performed in the copying operation is set at 25 yen, but it is needless to say that other charges may be used. Further, it is a matter of course that the frequency of the monochrome charging counter 901 and the frequency of the color charging counter 902 may not be the same, and for example, only 1 frequency = 25 yen in the case of the color charging counter 902.
[0122]
As described above, according to the fifth embodiment, the monochrome charging counter 901 that manages the charging related to the public line usage fee of the monochrome printing and facsimile functions, and the color charging counter 902 that manages the charging related to the color printing. Since two counters are used, accounting management for monochrome printing or color printing can be easily performed, and accurate accounting management can be performed.
[0123]
Furthermore, when color printing is designated from the transmission side during facsimile reception, the charging related to the printing operation is performed by the color charging counter 902, so that more accurate charging management can be performed.
[0128]
