An embodiment described here generally relates to an image reading apparatus and an image forming apparatus.
Conventionally, image reading apparatuses such as scanners mounted on digital multifunction peripherals operate at a scan speed and a processing speed that are set in factories or at the time of setting up. In the conventional image reading apparatuses, the scan speed and the processing speed that have been set before users use them cannot be changed. Normally, the scan speed and the processing speed are often reflected to the price of the image forming apparatus. Therefore, users who focus on the costs have to buy low-speed machines and users who focus on the processing speed have to buy high-speed machines.
However, in actual operation, image reading apparatuses such as scanners provided in digital multifunction peripherals can be used with no problem in low-speed processing focusing on the costs, but high-speed processing is sometimes required. Conventional image reading apparatuses cannot realize operation to perform low-speed scan processing in default settings so as to reduce the costs and to temporarily increase the costs so as to perform high-speed scan processing. In recent years, improvement of the productivity of the scan processing of the image reading apparatus such as the scanner provided in the digital multifunction peripheral has been focused along with increasing paperless demands. Therefore, it is desirable to provide an image reading apparatus and a system that are capable of performing scan processing according to a user’s request and improving the productivity of a scanner.
In accordance with one embodiment, an image reading apparatus includes a scanner, an operation panel, a storage device, and a processor. The scanner reads an image of a document at a set scan speed. The operation panel inputs an operating speed of a scan job using the scanner. The storage device includes a scan counter that stores, for each scan speed, a count value of the number of pages of the image read by using the scanner. The processor sets a scan speed corresponding to the operating speed input by the operation panel. The processor executes the scan job at the set scan speed. In addition, the processor updates the scan counter in accordance with the number of pages of the image read at the set scan speed.
Hereinafter, this embodiment will be described with reference to the drawings. In the drawings, the same reference signs denote the same or similar portions. First of all, a configuration of a digital multifunction peripheral (MFP) 1 serving as an image forming apparatus according to the embodiment will be described.
As shown in
The scanner 2 has a carriage 12, a photoelectric conversion device 13, and the like. The carriage 12, the photoelectric conversion device 13, and the like are installed below the document table glass 11. The carriage 12 includes an optical system such as an illumination device 62 (see
Moreover, the carriage 12 is moved in a sub-scanning direction below the document table glass 11 through a moving mechanism 63 (see
The photoelectric conversion device 13 has a lens, a photoelectric conversion sensor, a cover, and the like. The lens collects light guided by the optical system of the carriage 12 and guides the light to the photoelectric conversion sensor. The photoelectric conversion sensor includes photoelectric conversion elements. The photoelectric conversion sensor is, for example, a line sensor in which CCDs or CISs serving as the photoelectric conversion elements are arranged in a line form. The line sensor serving as the photoelectric conversion sensor converts an image for one line (reflected light on the document surface) in the main scanning direction into pixel data for one line.
The carriage 12 moved by the moving mechanism 63 moves the reading position on the document table glass 11 in the sub-scanning direction. The scanner 2 reads the entire image of the document by acquiring image data in the main scanning direction through the photoelectric conversion device 13 while moving the carriage 12 in the sub-scanning direction. The scanner 2 controls the reading speed of the image in the sub-scanning direction by controlling the movement of the carriage 12. Moreover, in accordance with the movement speed of the carriage 12, the scanner 2 controls the timing for acquiring the pixel data for one line in the main scanning direction from the line sensor. Accordingly, the scanner 2 controls the reading speed (scan speed) of the entire image of the document set on the document table glass 11.
The scanner 2 has an auto document feeder (ADF) 14. Hereinafter, the auto document feeder 14 will be abbreviated as the ADF 14. The ADF 14 also functions as a document table cover and is installed on a document table 10 so as to be capable of being opened and closed. When the ADF 14 is closed, the ADF 14 covers the entire document reading region on the document table glass 11. Moreover, the ADF 14 includes a sheet feeding tray, a transport system, and the like. The sheet feeding tray of the ADF 14 retains a document that is a reading target. The transport system of the ADF 14 takes out a document set on the sheet feeding tray one by one and conveys the document so that a reading surface of the taken-out document passes through a predetermined reading position.
The scanner 2 controls the reading speed of the image in the sub-scanning direction by controlling the transport speed at which the ADF 14 transports the document. Moreover, in accordance with the document transport speed of the ADF 14, the scanner 2 controls the timing for acquiring the pixel data for one line in the main scanning direction from the line sensor. Accordingly, the scanner 2 controls the reading speed (scan speed) of the entire image of the document set in the ADF 14.
The printer 3 has a sheet feeding mechanism 20. The sheet feeding mechanism 20 includes sheet feeding cassettes 21A, 21B, 21C and sheet feeding rollers 22A, 22B, 22C. The sheet feeding cassettes 21A, 21B, 21C house paper sheets serving as image-formed media on which images are to be printed. For example, each of the sheet feeding cassettes 21A, 21B, 21C is capable of being attached and detached to/from a lower portion of the main body of the digital multifunction peripheral. The sheet feeding cassettes 21A, 21B, 21C have the sheet feeding rollers 22A, 22B, 22C, respectively. The sheet feeding rollers 22A, 22B, 22C are provided in association with the sheet feeding cassettes 21A, 21B, 21C, respectively. The paper sheets are taken out from each of the sheet feeding cassettes 21A, 21B, 21C one by one.
A conveying mechanism 23 conveys the paper sheets in the printer 3. The conveying mechanism 23 includes a plurality of transport rollers 23a to 23d, a resistance roller 24, and the like. The conveying mechanism 23 conveys a paper sheet taken out by each of the sheet feeding rollers 22A, 22B, 22C to the resistance roller 24. The resistance roller 24 conveys the paper sheet to a secondary transfer position to be described later at an image transfer timing.
A plurality of image forming devices 25 (25Y, 25M, 25C, 25K) forms images in colors (yellow, magenta, cyan, black) respectively. The light exposure device 26 forms electrostatic latent images serving as images developed in the colors on image carriers in the image forming devices 25 (25Y, 25M, 25C, 25K) respectively. The light exposure device 26 forms the electrostatic latent images on the image carriers by scanning the image carriers with light emitted in accordance with the image data. For example, the light exposure device 26 emits light emitted from a light-emitting portion to photosensitive drums serving as the image carriers via rotated polygon mirrors, thereby scanning them in the main scanning direction. Moreover, rotation of the photosensitive drums moves the position to which the light exposure device 26 emits light in the sub-scanning direction. That is, the positions and scales of images formed by the image forming devices 25 are adjusted by controlling the light exposure device 26.
The image forming devices 25 (25Y, 25M, 25C, 25K) develop electrostatic latent images on the image carriers with toners in colors (yellow, magenta, cyan, black), respectively. An intermediate transfer belt 27 is an intermediate transfer member. The image forming devices 25 transfer (primarily transfer) toner images in the respective colors developed with the respective color toners in the image carriers to the intermediate transfer belt 27.
The intermediate transfer belt 27 retains the transferred toner images and transports the transfer toner images to the secondary transfer position. The secondary transfer position is a position where the toner images on the intermediate transfer belt 27 are transferred to a paper sheet. The secondary transfer position is a position where a support roller 28a and a secondary transfer roller 28b face each other. The support roller 28a and the secondary transfer roller 28b constitute a transfer device 28. The resistance roller 24 conveys the paper sheet to the secondary transfer position in synchronization with the toner image on the intermediate transfer belt 27. The transfer device 28 transfers the toner images retained on the intermediate transfer belt 27 to the paper sheet at the secondary transfer position.
For example, for forming a color image, the image forming devices 25Y, 25M, 25C, and 25K transfer toner images developed with toners in colors (yellow, magenta, cyan, black) respectively, superimposed on the intermediate transfer belt 27. The intermediate transfer belt 27 retains the color image in which the color toner images overlap. The transfer device 28 transfers the color image with the multicolor toners on the intermediate transfer belt 27 to the paper sheet at the secondary transfer position. The resistance roller 24 conveys the paper sheet to the secondary transfer position in synchronization with the toner image on the intermediate transfer belt 27. Accordingly, the color image is transferred to the paper sheet.
The transfer device 28 supplies a fixing device 29 with the paper sheet to which the toner images are transferred. The fixing device 29 fixes the toner images on the paper sheet. The fixing device 29 has a heater 29a, a heat roller 29b, and a press roller 29c. The heater 29a heats the heat roller 29b. The heat roller 29b and the press roller 29c perform fixation in which the paper sheet to which the toner images are transferred by the transfer device 28 is heated in a pressed state. The heat roller 29b and the press roller 29c in the fixing device 29 transports the fixed paper sheet to a transport roller 23d. The transport roller 23d conveys the paper sheet from the fixing device 29 to a sheet delivery portion 30.
The operation panel 4 is a user interface. The operation panel 4 displays a guide and receives an input via an operation button or icon. For example, a user inputs setting information in the operation panel 4. The operation panel 4 has a display device (display) 41, a touch panel 42, and a plurality of operation buttons 43. For example, the touch panel 42 is provided on a display screen of a display device 41. The touch panel 42 detects a point on the display screen of the display device 41, which is touched by the user.

Moreover, the image processing device 53 includes a processor for image processing. It is assumed that the operating frequency (operating speed) of the processor for image processing in the image processing device 53 is variable. The image processing device 53 changes the processing time related to the image processing by changing the operating frequency of the processor.

In accordance with an operation instruction from the processor 50, the processor 60 changes the movement speed of the carriage 12 by the moving mechanism 63. For example, in a case where a scan speed 1.5 times a default setting value is designated, the moving mechanism 63 moves the carriage 12 at the speed 1.5 times the default value.

In a case where the instruction to execute the scan processing has been made (YES in ACT12), the processing of the processor 50 shifts to ACT13. In ACT13, the processor 50 determines whether or not the instruction to change the operating speed has been made. In a case where the instruction to change the operating speed has been made (YES in ACT13), the processing of the processor 50 shifts to ACT14. In ACT14, the processor 50 sets the scan speed to the designated operating speed.
For example, when the “scan” button 422 is operated, in a state in which the “1.5 X” button 425 is operated for instruction, the processor 50 sets the operating speed (scan speed) to be 1.5 times the default value (1.5 X speed). Moreover, when the “scan” button 422 is operated in a state in which the “2 X” button 426 has been operated, the processor 50 sets the scan speed to be twice the default value (2 X speed) .
For example, for reading a document set on the ADF, the processor 50 changes the ADF’s paper feeding speed of the document, a pixel data acquiring timing of the photoelectric conversion device 13, and the like in accordance with the designated scan speed. Moreover, for reading the document on the document table, the processor 50 changes a carriage moving speed of the moving mechanism 63, the pixel data acquiring timing of the photoelectric conversion device 13, and the like in accordance with the designated scan speed.
After the operating speed is changed, in ACT15, the processor 50 executes the scan processing (scan job) of the document using the scanner 2 at the set operating speed. In ACT16, every time an image of a document is read for one page during execution of the scan job, the processor 50 updates (counts up) the scan counter associated with the scan mode of the set (changed) scan speed (any one counter of the counters 5414 to 5419). For example, in a case where the color (full color) image has been scanned at 1.5 X speed, the processor 50 counts up the counter 5414 associated with the 1.5 X full color scan. Moreover, in a case where a black and white (black) image has been scanned at 2 X speed, the processor 50 counts up the counter 5419 associated with the 2 X black scan.
When the scan job ends, in ACT17, the processor 50 changes setting of the operating speed to be the default value. Accordingly, after the scan job has been executed at the operating speed designated by the user, the digital multifunction peripheral 1 is capable of returning the operating speed to the default value. It should be noted that in a case where a predetermined time has elapsed after the scan job ends, the processor 50 may change setting of the operating speed to the default value.
Moreover, in a case where the instruction to change the operating speed has not been made (NO in ACT13), the processing of the processor 50 shifts to ACT18. In ACT18, the processor 50 does not change the default setting value and performs the scan processing. In ACT19, for executing the scan processing with the default value, the processor 50 counts up the scan counter associated with the scan mode that is the default value (any one counter of the counters 5411 to 5413) every time an image of a document is read for one page.
As described above, the digital multifunction peripheral serving as the image reading apparatus according to the embodiment receives an instruction to change the scan speed before scanning. In a case where an instruction to change the scan speed has been made, the digital multifunction peripheral changes the scan speed in accordance with the designated operating speed. The digital multifunction peripheral counts the number of scans for each scan speed during execution of the scan job.
Accordingly, the digital multifunction peripheral serving as the image reading apparatus is capable of changing the scan speed in accordance with the user’s instruction and managing the number of scans at each operating speed. As a result, in the digital multifunction peripheral serving as the image reading apparatus, an operation to charge a price for the use depending on the scan speed and the number of scans can be performed.
Although the above-mentioned operation example has been described assuming the scan operation, the digital multifunction peripheral 1 may make the operating speed variable (accelerate) also for scan operations in fax sending and the like. Also in this case, the digital multifunction peripheral counts the number of scans for each operating speed through the scan counter. Accordingly, the scan speed in fax processing can also be changed, and the number of scans can be counted for each scan speed. Moreover, in a case where an instruction to accelerate the fax processing has been made, the digital multifunction peripheral 1 may accelerate the data processing for conversion into fax data. For example, the digital multifunction peripheral may accelerate the data processing by increasing the operating frequency of the processor that executes the data processing of converting a scan image into fax data.
Next, a copy operation in the digital multifunction peripheral 1 serving as the image forming apparatus according to the embodiment will be described.
In ACT32, the processor 50 determines whether or not an instruction to execute the copy processing has been made. In a case where the instruction to execute the copy processing has been made (YES in ACT32), the processing of the processor 50 shifts to ACT33. In ACT33, the processor 50 determines whether or not an instruction to change the operating speed has been made. In a case where the instruction to change the operating speed has been made (YES in ACT33), the processing of the processor 50 shifts to ACT34. In ACT34, the processor 50 sets the scan speed and the print speed (copy speed) to be the designated operating speed. Here, it is assumed that the copy operating speed (copy speed) is realized by changing the scan speed and the print speed from the default value.
For example, when the “copy” button 421 is operated in a state in which the “1.5 X” button 425 has been operated, the processor 50 sets the scan speed and the print speed to be 1.5 times the default value (1.5 X speed). Moreover, when the “copy” button 421 is operated in a state in which the “2 X” button 426 has been operated, the processor 50 sets the scan speed and the print speed to be twice the default value (2 X speed). Moreover, in the copy, image processing and the like of converting images read by the scanner 2 into image data for printing are also performed. In order to reduce the time required for image processing in the copy, the processor 50 may set (change) the operating frequency of the processor that performs the image processing in accordance with the designated operating speed.
After the operating speed is changed, in ACT35, the processor 50 executes the copy processing (copy job) at the set operating speed. During execution of the copy job, every time an image of a document is read for one page, in ACT36, the processor 50 updates (counts up) the scan counter (any one counter of the counters 5414 to 5419) at the set (changed) scan speed corresponding to the scan mode. Moreover, in ACT37, every time an image for one page is printed on a paper sheet during execution of the copy job, the processor 50 counts up updates the print counter (any one counter of the counters 5424 to 5429) at the set print speed corresponding to the print mode.
For example, for executing the color (full color) copy at 1.5 X speed, the processor 50 counts up the scan counter 5414 associated with the 1.5 X full color scan. Moreover, for executing the color copy at 1.5 X speed, the processor 50 counts up the print counter 5424 associated with the 1.5 X full color print. Moreover, for executing the black and white (black) copy at 2 X speed, the processor 50 counts up the scan counter 5419 associated with the 2 X black scan and counts up the print counter 5429 associated with the 2 X black print.
When the copy job ends, in ACT37, the processor 50 changes setting of the operating speed to be the default value. Accordingly, when the copy job at the operating speed designated by the user ends, the digital multifunction peripheral 1 is capable of returning the setting value of the operating speed to the default setting value. It should be noted that in a case where a predetermined time has elapsed after the copy job ends, the processor 50 may change (return) setting of the operating speed to the default value.
Moreover, in a case where the instruction to change the operating speed has not been made (NO in ACT33), the processing of the processor 50 shifts to ACT39. In ACT39, the processor 50 does not change the default setting value and performs the scan processing. In a case of performing the copy processing with the default value, in ACT40, the processor 50 counts up the scan counter associated with the scan mode that is the default value (any one counter of the counters 5411 to 5413) every time an image of a document is read for one page. In addition, the processor 50 updates the print counter (any one counter of the counters 5421 to 5423) associated with the print mode that is the default value every time an image of a document for one page is printed on a paper sheet.
As described above, the digital multifunction peripheral serving as serving as the image forming apparatus according to the embodiment receives an instruction to change the copy speed before the copy is executed. In a case where the instruction to change the copy speed has been made, the digital multifunction peripheral changes the operating speed including the scan speed and the print speed in accordance with the designated operating speed. For executing the copy, the digital multifunction peripheral counts the number of scans and the number of prints at each operating speed.
Accordingly, a digital multifunction peripheral serving as the image forming apparatus is capable of changing the copy speed in accordance with the user’s instruction and managing the number of scans and the number of prints at each operating speed. As a result, in the digital multifunction peripheral serving as the image forming apparatus, an operation to charge a price for the use depending on the operating speed for the number of scans and the number of prints can be performed.
It should be noted that for the digital multifunction peripheral according to the embodiment, an administrator may set the operating speed. In this case, the digital multifunction peripheral during operation (after shipment) is capable of setting the operating speed (scan speed, print speed) for the scan speed and the print speed in accordance with the administrator’s instruction. For example, in a case where the administrator has instructed to set the operating speed (scan speed, print speed) to be N times the operating speed, the digital multifunction peripheral sets the operating speed to be N times the default value as the administrator has instructed. In this case, the digital multifunction peripheral may keep the operating speed N times the default value until the digital multifunction peripheral receives an instruction to return the operation setting to the default value from the administrator.
