Description

The present invention relates to an image adjustment device, an image forming device, an image adjustment method, and an image adjustment program.

Some image forming devices have a front-back adjustment function that adjusts the shift amount (amount of movement from the current position) and magnification of the print image formed on the front and back of the paper (recording medium). The front-back adjustment function allows manual adjustment, in which case, when the user inputs the shift amount, magnification, etc., the print image is formed based on the input shift amount, magnification, etc. (manual adjustment function).

The front/back adjustment function also allows for automatic adjustment, in which case the position of an adjustment mark formed on the paper is detected, and the shift amount, magnification, etc. are automatically adjusted based on the detected position to form an image to be printed (automatic adjustment function). For example, in Patent Document 1, the position of an adjustment mark is detected, and the shift amount, magnification, etc. are automatically adjusted using the amount of deviation between the detected position and the design position of the adjustment mark.

If the user wishes to change the position at which the image to be printed is formed to a desired position, the user can use the manual adjustment function described above to set the shift amount of the image to be printed to the desired shift amount.

Depending on the type of paper, it may shrink during image formation, or there may be size errors for each type of paper. In such cases, the user will use the manual adjustment function described above to set the magnification of the image to be printed to the desired magnification in order to form an image to be printed of a specific size without being affected by shrinkage of the paper during image formation or errors in paper size.

JP 2017-32922 A

Even when using the automatic adjustment function, there are cases where the user wishes to use the shift amount set by the user using the manual adjustment function. However, in the past, even if the user set a desired shift amount using the manual adjustment function, if the automatic adjustment function was used after the setting, the shift amount would be automatically adjusted based on the position of the detected adjustment mark, and would be changed from the shift amount set by the user.

In addition, even if a user sets a desired magnification using the manual adjustment function, if the automatic adjustment function is then used after that setting, the magnification is automatically adjusted based on the position of the detected adjustment mark, and is changed from the magnification set by the user. In other words, the magnification is automatically adjusted to match the actual paper size (taking into account paper shrinkage and paper size errors).

As described above, when using the automatic adjustment function, the shift amount, magnification, etc. are automatically adjusted regardless of the settings entered by the user, so there are cases where the form of the print image (shift amount, magnification, etc.) cannot be formed as intended by the user.

The following describes in detail the embodiments of the present invention with reference to the drawings.

Figure 1 is a diagram showing the overall configuration of an image forming apparatus 100 according to this embodiment. Figure 2 is a diagram showing the main parts of the control system of the image forming apparatus 100 according to this embodiment. Note that the configuration and specifications of the image forming apparatus 100 described below are an example of this embodiment, and are not limited to the following description, and can be modified as appropriate by arbitrarily selecting similar well-known technologies.

The image forming device 100 is capable of forming an image on paper (recording medium). As shown in FIG. 1, the image forming device 100 includes an image forming device main body 110, a reading device 120 (detection unit), and the like.

[Image forming apparatus body]
The image forming apparatus main body 110 is a color image forming apparatus of an intermediate transfer type that utilizes electrophotographic process technology. That is, the image forming apparatus main body 110 primarily transfers each color toner image of CMYK formed on a photoconductor to an intermediate transfer body, superimposes the four color toner images on the intermediate transfer body, and then secondarily transfers them onto paper to form an image to be printed. CMYK stands for C (cyan), M (magenta), Y (yellow), and K (black).

The image forming device main body 110 also uses a tandem system in which photoconductors corresponding to the four colors CMYK are arranged in series in the running direction of the intermediate transfer body, and each color toner image is transferred sequentially to the intermediate transfer body in a single step.

As shown in FIG. 1, the image forming device main body 110 includes an image reading unit 10, an operation display unit 20, an image processing unit 30, an image forming unit 40, a paper transport unit 50, and a fixing unit 60.

The image reading unit 10 includes an automatic document feeder 11, also known as an ADF (Auto Document Feeder), and a document image scanning device 12 (scanner).

The automatic document feeder 11 transports documents placed on a document tray using a transport mechanism and sends them to the document image scanning device 12. The automatic document feeder 11 can continuously read the images (including both sides) of multiple documents placed on the document tray all at once.

The document image scanning device 12 optically scans the document transported from the automatic document feeder 11 onto the contact glass or the document placed on the contact glass, and forms an image of the reflected light from the document on a CCD (Charge Coupled Device) sensor to read the document image. The image reading unit 10 generates input image data based on the results of the reading by the document image scanning device 12. This input image data is subjected to a predetermined image processing in the image processing unit 30.

The operation display unit 20 is, for example, a liquid crystal display (LCD) with a touch panel, and functions as a display unit 21 and an operation unit 22. The display unit 21 displays various operation screens, image status displays, and the operating status of each function according to a display control signal input from the control unit 70 (see FIG. 2). The operation unit 22 has various operation keys such as a numeric keypad and a start key, accepts various input operations by the user, and outputs operation signals to the control unit 70.

The image processing unit 30 includes a circuit that performs image processing on input image data according to initial settings or user settings. The image forming unit 40 is controlled based on the image data that has been subjected to image processing.

The image forming section 40 includes image forming units 41Y, 41M, 41C, and 41K, and an intermediate transfer unit 42 for forming images using color toners of the Y, M, C, and K components based on image data from the image processing section 30.

The image forming units 41Y, 41M, 41C, and 41K for the Y, M, C, and K components have the same configuration. Therefore, in FIG. 1, only the components of the image forming unit 41Y for the Y component are labeled, and the components of the other image forming units 41M, 41C, and 41K are not labeled.

The image forming unit 41 includes an exposure device 411, a developing device 412, a photosensitive drum 413, a charging device 414, a drum cleaning unit 415, etc.

The exposure device 411 is composed of, for example, a semiconductor laser, and irradiates the photoconductor drum 413 with laser light corresponding to an image of each color component. Positive charges are generated in the charge generation layer of the photoconductor drum 413 by irradiation with the laser light, and when the charges are transported to the surface of the charge transport layer, the surface charge (negative charge) of the photoconductor drum 413 is neutralized. As a result, an electrostatic latent image of each color component is formed on the surface of the photoconductor drum 413 due to the potential difference with the surroundings.

The developing device 412 is, for example, a two-component developing device having a developing sleeve. The developing device 412 visualizes the electrostatic latent image and forms a toner image by depositing toner of each color component from the developing sleeve onto the surface of the photoconductor drum 413.

The photoconductor drum 413 includes, for example, an aluminum conductive cylinder (aluminum tube), an undercoat layer (UCL), a charge generation layer (CGL), and a charge transport layer (CTL). The photoconductor drum 413 is a photoconductor having photoconductivity, which is configured by sequentially laminating an undercoat layer, a charge generation layer, and a charge transport layer on the circumferential surface of a conductive cylinder. The photoconductor drum 413 is, for example, a negatively charged organic photoconductor (OPC). The photoconductor drum 413 is rotated at a constant peripheral speed (linear speed) by the control unit 70 (see FIG. 2) controlling the drive current supplied to the drive motor (not shown).

The charging device 414 uniformly charges the surface of the photoconductive photoconductor drum 413 to a negative polarity.

The drum cleaning unit 415 uses a cleaning blade to clean residual toner remaining on the surface of the photosensitive drum 413. The drum cleaning unit 415 may also include a lubricant supplying device that supplies a lubricant (gliding agent) onto the photosensitive drum 413 to reduce the adhesion of the toner to the photosensitive drum 413.

The intermediate transfer unit 42 includes an intermediate transfer belt 421, a primary transfer roller 422, a plurality of support rollers 423 including a backup roller 423A, and a secondary transfer roller 424. The intermediate transfer unit 42 may also include a belt cleaning device that removes residual toner remaining on the surface of the intermediate transfer belt 421 after the secondary transfer, for example, by a belt cleaning blade that is in sliding contact with the surface of the intermediate transfer belt 421.

The intermediate transfer belt 421 is stretched in a loop around a number of support rollers 423, and as the support rollers 423 rotate, the intermediate transfer belt 421 travels at a constant speed in the direction of arrow A. The primary transfer roller 422 presses the intermediate transfer belt 421 against the photosensitive drum 413. This transfers the toner image from the photosensitive drum 413 to the intermediate transfer belt 421. The secondary transfer roller 424 is pressed against the backup roller 423A, sandwiching the intermediate transfer belt 421 between them. This transfers the toner image from the intermediate transfer belt 421 to the paper. The paper to which the toner image has been transferred is transported toward the fixing unit 60. Note that instead of the secondary transfer roller 424, a belt-type secondary transfer unit in which the secondary transfer belt is stretched in a loop around a number of support rollers may be used.

The paper transport section 50 includes a paper feed section 51, a paper discharge section 52, a transport path section 53, and a reversing mechanism section 54. The three paper feed tray units 51a to 51c that make up the paper feed section 51 store paper (standard paper, special paper) identified based on basis weight, size, etc., by preset type. The transport path section 53 has multiple transport roller pairs, such as registration roller pairs.

The sheets of paper stored in the paper feed tray units 51a to 51c are sent out one by one from the top and transported to the image forming unit 40 by the transport path section 53. At this time, the tilt of the fed paper is corrected and the transport timing is adjusted by the registration roller section, which has a pair of registration rollers. The paper on which an image has been formed through the image forming unit 40 and the fixing unit 60 is then discharged outside the machine by the paper discharge section 52. When forming images for printing on both sides of the paper, the paper surface is reversed by the reversing mechanism section 54, and the paper is transported again to the image forming unit 40 (secondary transfer roller 424).

The fixing unit 60 heats and presses the paper, which has been transported after the secondary transfer of the toner image, in a fixing nip, thereby fixing the toner image to the paper. The fixing unit 60 includes a fixing roller 61 and a pressure roller 62. The fixing roller 61 and the pressure roller 62 form a fixing nip that holds and transports the paper between them. Note that instead of the fixing roller 61, a belt-type fixing unit in which a fixing belt is stretched in a loop around multiple support rollers may be used.

The image forming device main body 110 forms a print image on the front and back of the paper using the above-mentioned configuration. The image forming device main body 110 also forms a plurality of adjustment marks (adjustment images) in the margin areas on the front and back of the paper using the above-mentioned configuration. For example, in the margin areas on the front and back of the paper, cross-shaped adjustment marks (register marks) are image-formed near each of the four corners of the paper. At this time, the adjustment marks are formed so that they are positioned a predetermined distance away from the edge of the paper, with the edge being used as the reference. Note that the adjustment marks may be formed anywhere in the margin areas of the paper.

[Reading device]
As shown in Fig. 1, the reading device 120 is disposed downstream of the image forming device main body 110 in the paper conveying direction in the image forming device 100, and includes a first sensor 121, a second sensor 122, etc. When adjustment marks are formed on both sides of a paper by the image forming device main body 110, the reading device 120 is configured to be able to detect the adjustment marks by scanning (reading) both sides of the paper with the first sensor 121 and the second sensor 122. The reading device 120 is also able to detect the paper edge (paper size) with the first sensor 121 and the second sensor 122. The detection results (reading results) of the adjustment marks and the paper edge by the reading device 120 are stored in the memory unit 82 described later and are used by the control unit 70.

The first sensor 121 is disposed upstream in the paper transport direction within the reading device 120, and reads the paper passing by from below. The first sensor 121 is an optical sensor that can read at a relatively high speed, such as a line scanner. Therefore, it can detect adjustment marks formed on the edge of the paper, etc., at a relatively high speed and output the detection result. The first sensor 121 is also an optical sensor with a length that spans the entire width of the paper. Therefore, it can read the entire width of the paper.

The second sensor 122 is disposed downstream in the paper transport direction within the reading device 120 and reads the paper passing through from above. The second sensor 122 is configured in the same manner as the first sensor 121.

The positional relationship between the first sensor 121 and the second sensor 122 may be reversed, and within the reading device 120, the second sensor 122 may be disposed upstream in the paper transport direction, and the first sensor 121 may be disposed downstream in the paper transport direction.

In addition, here, two sensors, a first sensor 121 and a second sensor 122, are provided, but if a mechanism equivalent to the above-mentioned reversing mechanism unit 54 is provided in the reading device 120, it is sufficient to provide either one of these sensors.

In addition, here, the reading device 120 is an independent device separate from the image forming device main body 110, but it may be provided inside the image forming device main body 110. In that case, the reading device 120 is disposed downstream of the fixing unit 60 in the paper transport direction in the image forming device main body 110.

[Control unit]
As shown in FIG. 2, the image forming apparatus 100 includes a control unit 70 .

The control unit 70 functions as a computer and includes a CPU (Central Processing Unit) 71, a ROM (Read Only Memory) 72, and a RAM (Random Access Memory) 73. The CPU 71 reads a program corresponding to the processing contents from the ROM 72, loads it into the RAM 73, and centrally controls the operation of each block of the image forming device 100 in cooperation with the loaded program. At this time, various data such as a LUT (Look Up Table) stored in the memory unit 82 is referenced. The memory unit 82 is composed of, for example, a non-volatile semiconductor memory (so-called flash memory) or a hard disk drive.

The control unit 70 transmits and receives various data to and from an external device (e.g., a personal computer) connected to a communication network such as a LAN (Local Area Network) or a WAN (Wide Area Network) via the communication unit 81. The control unit 70 receives, for example, image data transmitted from an external device, and forms an image to be printed on paper based on this image data (input image data). The communication unit 81 is, for example, composed of a communication control card such as a LAN card.

The image reading unit 10, operation display unit 20, image processing unit 30, image forming unit 40, paper transport unit 50, and fixing unit 60 are each connected to the control unit 70. The reading device 120 is also connected to the control unit 70. These perform predetermined processing based on instructions from the control unit 70.

[Adjustment section]
In the image forming apparatus 100, an adjustment unit is configured that automatically adjusts the image adjustment values of the adjustment items constituting the formation mode of the image to be printed, by using the image forming apparatus main body 110 and the reading device 120 described above, to automatically adjust the formation mode of the image to be printed. In this way, the adjustment unit has an automatic adjustment function that automatically adjusts the image adjustment values of the adjustment items. The image adjustment values of the adjustment items that are automatically adjusted by the adjustment unit include the amount of movement (shift amount) for moving the position of the image to be printed, the magnification of the image to be printed, the rotation of the image to be printed, the distortion of the image to be printed, the inclination of the image to be printed, or the curvature of the image to be printed.

Specifically, the adjustment unit detects the adjustment mark formed on the paper using the first sensor 121 and the second sensor 122 of the reading device 120. When automatically adjusting the shift amount, for example, the control unit 70 calculates the distance from the edge of the paper based on the position of the detected adjustment mark, and automatically adjusts the shift amount based on the difference between the calculated distance and a predetermined distance from the edge of the paper to the adjustment mark. The image forming device main body 110 then forms an image to be printed on the paper using the automatically adjusted shift amount.

In this way, the adjustment unit automatically adjusts the image adjustment values of the adjustment items of the image to be printed, but there are cases where the user wishes to set the image adjustment values of the adjustment items of the image to be printed to desired values. In such cases, the shift amount, magnification, etc. of the image to be printed can be set to desired values using the input reception screens Sc1 and Sc2 shown in Figures 3 and 4, which will be described later (manual adjustment function).

However, in the past, even if a user used the manual adjustment function to set a desired shift amount or magnification, if the adjustment unit was used after the setting, the shift amount or magnification would be automatically adjusted based on the position of the detected adjustment mark. In other words, the shift amount or magnification set by the user was changed against the user's will.

As described above, when using the adjustment unit, the shift amount, magnification, etc. are automatically adjusted regardless of the settings input by the user, so there are cases where the printing image cannot be formed as intended by the user.

In this embodiment, the image forming apparatus 100 is provided with an image adjustment device having an input receiving unit and an adjustment unit, which will be described below. The image adjustment device executes an image adjustment method (image adjustment program) which will be described later with reference to Figures 7 to 9.

The input reception unit receives input of image adjustment values by the user (input reception process). The input reception unit will be described later with reference to Figures 3 and 4.

The adjustment unit is further configured, when input of image adjustment values is accepted, to adjust the formation mode of the print image on the paper by using the image adjustment values input by the user in priority over the results of reading the adjustment marks formed on the paper (adjustment process).

Such an input receiving unit and adjustment unit are provided as one function of the control unit 70. For example, the input receiving unit and adjustment unit are provided as a program executed by the control unit 70.

[Input Reception Unit and Manual Adjustment]
The control unit 70 (input receiving unit) will be described below with reference to Fig. 3 and Fig. 4. Fig. 3 is a diagram for explaining manual adjustment of front and back adjustment performed in the image forming apparatus 100, and is a diagram showing an operation screen for magnification and shift. Fig. 4 is a diagram for explaining manual adjustment of front and back adjustment performed in the image forming apparatus 100, and is a diagram showing an operation screen for adjustment items related to distortion. Note that in Figs. 3 and 4, image adjustment values are displayed as front and back adjustment values.

When the user inputs a shift amount or magnification as an image adjustment value, the control unit 70 (input reception unit) displays the operation screen Sc1 shown in FIG. 3 on the operation display unit 20, which is a touch panel.

In the operation screen Sc1, it is possible to set the tray. For example, when the user touches the operation area B11 that displays "Tray 1," tray 1 is selected as the tray for which image adjustment values can be input. When the user touches the operation area B12 that displays "Tray 2," tray 2 is selected as the tray for which image adjustment values can be input. When the user touches the operation area B13 that displays "Tray 3," tray 3 is selected as the tray for which image adjustment values can be input.

In FIG. 3, operation area B11 is selected, and operation areas B12 and B13 are not selected. To indicate this selected state, in FIG. 3, operation area B11 is displayed in white on a black background, and operation areas B12 and B13 are displayed in black on a white background.

In the operation screen Sc1, the user has touched the operation area B21 that is displayed as "Front," so it is possible to set the shift amount and magnification of the front side, which is the first side of the paper, as image adjustment values. Again, to indicate that the operation area B21 is selected, in FIG. 3, the operation area B21 is displayed in white on a black background.

When the user touches the operation area B22 that displays "Back," the shift amount and magnification of the back side, which is the second side of the paper, can be set as image adjustment values. The operation screen in this case is the same as the operation screen Sc1 shown in FIG. 3, except that the operation area B21 is displayed in black letters on a white background, and the operation area B22 is displayed in white letters on a black background.

Furthermore, when the user touches the operation area B23 labeled "Distortion," it is possible to set adjustment items related to distortion as image adjustment values. This will be explained with reference to FIG. 4. When the user touches the operation area B24 labeled "Front/Back Difference," it is possible to set the front/back difference in image adjustment values such as the shift amount and magnification. When the user touches the operation area B25 labeled "Auto Measurement," it is possible to perform automatic measurement for automatically adjusting the adjustment items of the image to be printed. This will be explained with reference to FIG. 5, which will be described later.

When the user touches operation area B31 marked "Vertical magnification" on operation screen Sc1, the vertical magnification of the image to be printed can be input as an image adjustment value. When the user touches operation area B32 marked "Horizontal magnification" the horizontal magnification of the image to be printed can be input as an image adjustment value. When the user touches operation area B33 marked "Top/Bottom," the amount of shift in the vertical direction (paper feed direction) of the image to be printed can be input as an image adjustment value. When the user touches operation area B34 marked "Left/Right," the amount of shift in the left/right direction (width direction) of the image to be printed can be input as an image adjustment value.

In FIG. 3, operation area B31 is selected, and operation areas B32 to B34 are not selected. To indicate this selected state, in FIG. 3, operation area B31 is displayed in white letters on a black background, and operation areas B32 to B34 are displayed in black letters on a white background.

The vertical magnification, horizontal magnification, vertical shift amount, and horizontal shift amount of the above-mentioned print image can be input by the user touching the areas showing numerical values or the areas showing up and down arrows displayed in the numerical input area B35 on the operation screen Sc1.

When the user touches the operation area B14 that displays "Close," the vertical magnification, horizontal magnification, vertical shift amount, and horizontal shift amount of the image to be printed input by the user are set. In other words, the vertical magnification, horizontal magnification, vertical shift amount, and horizontal shift amount of the image to be printed are set by manual input by the user (manual adjustment).

After this setting, when the user causes the image forming device 100 to execute an image forming process, the image forming device main body 110 executes the image forming process using the manually input image adjustment values. For example, the image forming section 40 of the image forming device main body 110 can shift (move) the image to be printed based on the manually input shift amount, thereby forming the image to be printed as intended by the user.

When the user inputs an adjustment item related to distortion as an image adjustment value, the control unit 70 (input reception unit) displays the operation screen Sc2 shown in FIG. 4 on the operation display unit 20.

Tray settings can also be made on operation screen Sc2, which is the same as operation screen Sc1 described above, so duplicate explanations will be omitted.

In operation screen Sc2, the user touched operation area B23, which is displayed as "Distortion," so it is possible to set an adjustment item related to distortion as an image adjustment value. Again, to indicate that operation area B23 is selected, in FIG. 4, operation area B23 is displayed in white on a black background.

On the operation screen Sc2, when the user touches the operation area B41 marked "Front," the user can set an adjustment item related to the distortion on the front side of the paper as an image adjustment value. Also, when the user touches the operation area B42 marked "Back," the user can set an adjustment item related to the distortion on the back side of the paper as an image adjustment value.

In FIG. 4, operation area B41 is selected, and operation area B42 is not selected. To indicate this selected state, operation area B41 is displayed in white on a black background, and operation area B42 is displayed in black on a white background in FIG. 4.

In addition, on the operation screen Sc2, when the user touches the operation area B43 marked "Rotation", the image adjustment value for the rotation of the image to be printed can be input. When the user touches the operation area B44 marked "Skew", the image adjustment value for the tilt of the image to be printed can be input. When the user touches the operation area B45 marked "Vertical Trapezoid", the image adjustment value for the vertical trapezoid of the image to be printed can be input. When the user touches the operation area B46 marked "Horizontal Trapezoid", the image adjustment value for the horizontal trapezoid of the image to be printed can be input. When the user touches the operation area B47 marked "Bend", the image adjustment value for the bend of the image to be printed can be input. When the user touches the operation area B48 marked "Bend Position", the image adjustment value for the bend position of the image to be printed can be input.

In FIG. 4, operation area B43 is selected, and operation areas B44 to B48 are not selected. To indicate this selected state, in FIG. 4, operation area B43 is displayed in white on a black background, and operation areas B44 to B48 are displayed in black on a white background.

The numeric input field B49 in the operation screen Sc2 is the same as the numeric input field B35 in the operation screen Sc1 shown in FIG. 3. Therefore, the user can input a numeric value into the image adjustment value described above by touching the area showing the numeric value or the area showing the up arrow or down arrow displayed in the numeric input field B49.

When the user touches the operation area B14 that displays "Close," the image adjustment values for rotation, tilt, vertical trapezoid, horizontal trapezoid, bend, and bend position input by the user are set. In other words, the image adjustment values for rotation, tilt, vertical trapezoid, horizontal trapezoid, bend, and bend position of the image to be printed are set by manual input by the user (manual adjustment).

After this setting, when the user causes the image forming device 100 to execute an image forming process, the image forming device main body 110 executes the image forming process using the manually input image adjustment values. For example, the image forming section 40 of the image forming device main body 110 can form the print image as intended by the user by rotating the print image based on the manually input image adjustment value for rotation.

[Adjustment section and automatic adjustment]
The control unit 70 (adjustment unit) will be described below with reference to Fig. 5 and Fig. 6. Fig. 5 is a diagram showing an operation screen for front and back adjustment performed in the image forming apparatus 100, showing a case where image adjustment values of all adjustment items are automatically adjusted. Fig. 6 is a diagram showing an operation screen for front and back adjustment performed in the image forming apparatus 100, showing a case where some image adjustment values of adjustment items are manually input and the rest are automatically adjusted. Note that the image adjustment values are also displayed as front and back adjustment values in Figs. 5 and 6.

The control unit 70 (adjustment unit) basically uses the results of reading the adjustment marks to automatically adjust the image adjustment values of the adjustment items of the image to be printed, and adjusts the manner in which the image to be printed is formed on the paper (see FIG. 5). Furthermore, in this embodiment, when the input of the image adjustment values is accepted, the control unit 70 (adjustment unit) is configured to adjust the manner in which the image to be printed is formed on the paper by using the manually input image adjustment values in preference to the results of reading the adjustment marks (see FIG. 6).

The following describes how to automatically adjust the image adjustment values of the adjustment items of the image to be printed using the results of reading the adjustment marks formed on the paper, with reference to Figure 5.

If the user does not input image adjustment values, when the user touches the operation area B25 displaying "Automatic Measurement", the control unit 70 (adjustment unit) displays the operation screen Sc3 shown in FIG. 5 on the operation display unit 20. For example, if the user does not input image adjustment values using the operation screens Sc1 and Sc2 shown in FIGS. 3 and 4, the control unit 70 (adjustment unit) displays the operation screen Sc3. Note that here too, to indicate that the operation area B25 is selected, the operation area B25 is displayed in white on a black background in FIG. 5.

In operation screen Sc3, adjustment item display area B51 displays the adjustment item, the front side image adjustment value, and the back side image adjustment value. In the case of operation screen Sc3, since the user did not input an image adjustment value, adjustment item display area B51 displays, for example, the initial values preset in image forming device 100 in black on a white background as the front side image adjustment value and back side image adjustment value for each adjustment item.

When the user touches the operation area B15 that displays "Go to print mode", the image forming device 100 forms adjustment marks on both sides of the paper, and the reading device 120 detects the adjustment marks on both sides of the paper using the first sensor 121 and the second sensor 122. The control unit 70 automatically adjusts the image adjustment values of the adjustment items based on the positions of the detected adjustment marks, and updates the image adjustment values in the adjustment item display area B51. When the user touches the operation area B14 that displays "Close", the image adjustment values of the adjustment items updated by automatic measurement are set (automatic adjustment).

After this setting, when the user causes the image forming device 100 to execute an image forming process, the image forming device main body 110 executes the image forming process using the image adjustment values of the adjustment items updated by the automatic measurement. For example, the image forming unit 40 of the image forming device main body 110 forms an image to be printed by shifting (moving) the image to be printed based on the shift amount updated by the automatic measurement.

Tray settings can also be made on operation screen Sc3, which is basically the same as operation screen Sc1 described above, but on operation screen Sc3, the user can select multiple trays. For example, on operation screen Sc3, when the user touches operation area B1 that displays "All Trays," all trays are selected, and when the user touches operation area B2 that displays "Multiple Trays," multiple trays are selected.

As an example, on the operation screen Sc3, the user touches the operation area B2 that displays "Multiple Trays," and then touches the operation area B11 that displays "Tray 1," and the operation area B12 that displays "Tray 2." To indicate that these are selected, the operation areas B2, B11, and B12 are displayed in white on a black background in FIG. 5.

With reference to Figure 6, we will explain how to adjust the formation of an image to be printed on paper by using manually input image adjustment values in preference to the results of reading adjustment marks formed on the paper.

After the user inputs the image adjustment values, when the user touches the operation area B25 displaying "Automatic Measurement", the control unit 70 (adjustment unit) displays the operation screen Sc4 shown in FIG. 6 on the operation display unit 20. For example, when the user inputs image adjustment values using the operation screens Sc1 and Sc2 shown in FIGS. 3 and 4, the control unit 70 (adjustment unit) displays the operation screen Sc4. Note that here too, to indicate that the operation area B25 is selected, the operation area B25 is displayed in white on a black background in FIG. 6.

In operation screen Sc4, the adjustment item display area B51 displays the adjustment item, the image adjustment value for the front side, and the image adjustment value for the back side. In the case of operation screen Sc4, the user inputs the image adjustment value before moving to this operation screen Sc4. For example, as shown in FIG. 3, assume that the user inputs the vertical magnification as "+1.00%" in operation screen Sc1. Then, the adjustment item for the vertical magnification and the image adjustment value are shown in white on a black background, for example, to indicate that they were input by the user. In other words, the control unit 70 uses the operation display unit 20, which functions as a notification unit, to notify the user that this image adjustment value will be used preferentially.

Note that here, the control unit 70 uses the operation display unit 20 to display the adjustment items and image adjustment values to be used with priority in white letters on a black background, but this is not limited to the above, and the control unit 70 may notify the user by changing the area or letters to another color or by making them blink. Furthermore, the control unit 70 may notify the user of the adjustment items and image adjustment values to be used with priority by voice, for example, using a speaker (not shown) as a notification unit.

For items for which the user has not input image adjustment values, the adjustment item display area B51 shows, for example, the initial values preset in the image forming device 100 in black on a white background as the front side image adjustment values and back side image adjustment values for each adjustment item.

When the user touches the operation area B15 that displays "Go to print mode", the image forming device 100 forms adjustment marks on both sides of the paper, and the reading device 120 detects the adjustment marks on both sides of the paper using the first sensor 121 and the second sensor 122. The control unit 70 automatically adjusts the image adjustment values for adjustment items other than the adjustment item input by the user based on the positions of the detected adjustment marks, and updates the image adjustment values in the adjustment item display area B51. When the user touches the operation area B14 that displays "Close", the image adjustment values of the adjustment items input by the user and the image adjustment values of the adjustment items updated by automatic measurement are set (partial automatic adjustment).

When the user causes the image forming device 100 to execute an image forming process after this setting, the image forming device main body 110 executes the image forming process using the image adjustment values of the adjustment items input by the user and the image adjustment values of the adjustment items updated by automatic measurement. For example, the image forming section 40 of the image forming device main body 110 shifts (moves) the image to be printed based on the shift amount input by the user, and rotates the image to be printed based on the image adjustment value of rotation updated by automatic measurement, thereby forming the image to be printed as intended by the user.

Conventionally, even if a user sets a desired shift amount or magnification using the manual adjustment function described above, if the automatic adjustment function is used after the setting, the shift amount or magnification is automatically adjusted based on the position of the detected adjustment mark. In contrast, in this embodiment, as described with reference to FIG. 6, the image adjustment value input by the user is given priority, so that the formation mode of the print image can be adjusted as the user intends.

[Image Adjustment Method During Image Formation Processing]
In the above description, the formation mode of the image to be printed is adjusted before the image forming process by the image forming apparatus 100, but the formation mode of the image to be printed may be adjusted during the image forming process. A method of adjusting the image during the image forming process will be described with reference to FIGS.

Here, FIG. 7 is a flowchart explaining an image adjustment method executed during image formation processing in image forming apparatus 100. FIG. 8 is a flowchart explaining a subroutine executed in step S15 of the flowchart shown in FIG. 7. FIG. 9 is a flowchart explaining a subroutine executed in step S16 of the flowchart shown in FIG. 7.

When a user performs an operation to start an image formation process in the image forming device 100, the control unit 70 executes the following procedure. The procedure described below is stored in the memory unit 82 as an image adjustment program executed by the control unit 70.

(Step S11)
The control unit 70 checks whether the adjustment stop mode is selected. If the adjustment stop mode is not selected (NO), the process proceeds to step S12. If the adjustment stop mode is selected (YES), the process proceeds to step S19.

Although not shown in the figure, the adjustment stop mode is instructed, for example, by the user selecting an operation area on the operation screen that displays "adjustment stop mode." This adjustment stop mode is a mode in which the control unit 70 (adjustment stop unit) stops automatic adjustment by the adjustment unit for all adjustment items. In this adjustment stop mode, the image adjustment values input for each adjustment item are used, as will be explained in step S19 below.

(Step S12)
The control unit 70 causes the image forming apparatus main body 110 to form image adjustment marks for the paper on which the image to be printed is formed. The image forming apparatus main body 110 forms image adjustment marks, for example, in the margins at the edges of the paper on both sides of the paper on which the image to be printed is formed. Note that the image adjustment marks may be formed not on the paper on which the image to be printed is formed, but on paper for image adjustment on which the image to be printed is not formed.

(Step S13)
The control unit 70 causes the reading device 120 to read the paper on which the image adjustment marks are formed. At this time, the first sensor 121 and the second sensor 122 of the reading device 120 detect not only the image adjustment marks formed on the paper, but also the edges of the paper.

(Step S14)
The control unit 70 determines the paper size of the paper on which the image adjustment marks are formed, based on the reading results of the reading device 120 (the first sensor 121 and the second sensor 122).

(Step S15)
The control unit 70 executes a subroutine for setting the shift amount. The subroutine for setting the shift amount will be described with reference to FIG.

(Step S151)
The control unit 70 checks whether a shift amount has been input. For example, when the user touches the operation area B33 marked "up and down" on the operation screen Sc1 shown in Fig. 3 and inputs a shift amount in the up and down direction, it is determined that a shift amount has been input. Also, when the user touches the operation area B34 marked "left and right" on the operation screen Sc1 shown in Fig. 3 and inputs a shift amount in the left and right direction, it is determined that a shift amount has been input. If a shift amount has been input (YES), the process proceeds to step S152, and if a shift amount has not been input (NO), the process proceeds to step S155.

(Step S152)
The control unit 70 checks whether the shift amount has been input for only one side. For example, when the user performs the following operation, it is determined that the shift amount has been input for only one side.

For example, this is the case when the user touches the operation area B21 displayed as "Front" or the operation area B22 displayed as "Back" and the operation area B33 displayed as "Up/Down" and inputs a vertical shift amount to either the front or back surface. Also, this is the case when the user touches the operation area B21 displayed as "Front" or the operation area B22 displayed as "Back" and the operation area B34 displayed as "Left/Right" and inputs a horizontal shift amount to either the front or back surface.

If it is determined that the shift amount has been input for only one side (step S152, YES), the process proceeds to step S153. On the other hand, if it is not determined that the shift amount has been input for only one side (step S152, NO), that is, if it is determined that the shift amount has been input for both sides, the process proceeds to step S154.

(Step S153)
If it is determined in step S152 that the shift amount has been input only for one side, the control unit 70 uses the input shift amount for one side as the shift amount for both sides of the paper. At this time, the control unit 70 may display the input shift amount for one side on the operation display unit 20 (notification unit) to notify the user.

(Step S154)
In step S152, if it is not determined that the shift amount has been input for only one side, that is, if it is determined that the shift amount has been input for both sides, the control unit 70 uses the shift amount input for each of the two sides of the paper as the shift amount for both sides of the paper. At this time, the control unit 70 may display the input shift amount for both sides on the operation display unit 20 (notification unit) to notify the user.

(Step S155)
If it is determined in step S<b>151 that the shift amount has not been input, the control unit 70 automatically adjusts the shift amount on both sides of the paper based on the reading result of the reading device 120 .

(Step S16)
The control unit 70 executes a subroutine for setting the magnification ratio. The subroutine for setting the magnification ratio will be described with reference to FIG.

(Step S161)
The control unit 70 checks whether a magnification has been input. For example, when the user touches the operation area B31 displayed as "Vertical magnification" on the operation screen Sc1 shown in Fig. 3 and inputs a vertical magnification, it is determined that a magnification has been input. Also, when the user touches the operation area B32 displayed as "Horizontal magnification" on the operation screen Sc1 shown in Fig. 3 and inputs a horizontal magnification, it is determined that a magnification has been input. If a magnification has been input (YES), the process proceeds to step S162, and if a magnification has not been input (NO), the process proceeds to step S166.

(Step S162)
The control unit 70 compares the paper size set by the user with the paper size determined based on the reading result of the reading device 120, and checks whether these paper sizes match. If the paper sizes do not match (NO), the process proceeds to step S163, and if the paper sizes match (YES), the process proceeds to step S166. The paper size set by the user is input using the operation display unit 20 before the image forming process. If the paper sizes do not match as a result of this determination process, the magnification input by the user is used preferentially, as described below.

(Step S163)
The control unit 70 checks whether the magnification has been input for only one side. For example, if the user performs the following operation, it is determined that the magnification has been input for only one side.

For example, this is the case when the user touches the operation area B21 displayed as "Front" or the operation area B22 displayed as "Back" and the operation area B31 displayed as "Vertical magnification", and the vertical magnification is input to either the front or back surface. Also, this is the case when the user touches the operation area B21 displayed as "Front" or the operation area B22 displayed as "Back" and the operation area B32 displayed as "Horizontal magnification", and the horizontal magnification is input to either the front or back surface.

If it is determined that the magnification has been input for only one side (step S163, YES), the process proceeds to step S164. On the other hand, if it is not determined that the magnification has been input for only one side (step S163, NO), that is, if it is determined that the magnification has been input for both sides, the process proceeds to step S165.

(Step S164)
If it is determined in step S163 that the magnification has been input only for one side, the control unit 70 uses the input magnification for one side as the magnification for both sides of the paper. At this time, the control unit 70 may display the input magnification for one side on the operation display unit 20 (notification unit) to notify the user.

(Step S165)
In step S163, if it is not determined that the magnification has been input for only one side, that is, if it is determined that the magnification has been input for both sides, the control unit 70 uses the magnifications input for both sides of the paper as the magnifications for both sides of the paper. At this time, the control unit 70 may display the input magnifications for both sides on the operation display unit 20 (notification unit) to notify the user.

(Step S166)
If it is determined in step S161 that no magnification has been input, and if it is determined in step S162 that the paper size matches, the control unit 70 automatically adjusts the magnification on both sides of the paper based on the reading results of the reading device 120.

In the subroutine shown in FIG. 9, if paper sizes are not compared, step S162 may be omitted. In that case, step S14 shown in FIG. 7 may also be omitted.

In addition, if the user sets paper characteristics included in the paper profile as paper-related items, the control unit 70 may be able to determine that the paper size will change (shrink) as a result of the image formation process based on the set paper characteristics. In that case, for example, the determination process described below may be executed between step S162 and step S163 shown in FIG. 9.

The control unit 70 determines whether the paper will shrink as a result of the image formation process based on the set paper characteristics. If it is determined that the paper will shrink, the process proceeds to step S163. If it is not determined that the paper will shrink, the process proceeds to step S166. The paper characteristics set by the user are input using the operation display unit 20 before the image formation process. If this determination process results in the paper shrinking as a result of the image formation process, the adjustment items input by the user are used with priority.

Returning to the flowchart shown in Figure 7, we will now explain steps S17 to S19.

(Step S17)
The control unit 70 uses image adjustment values input by the user and image adjustment values automatically adjusted based on the reading results of the reading device 120 to calculate the correction amounts for rotation, skew, trapezoid, and curvature of the image to be printed.

(Step S18)
The control unit 70 automatically adjusts the image adjustment values of the adjustment items that require adjustment. For example, if the rotation of the image to be printed needs to be adjusted due to the image adjustment values input by the user or the image adjustment values that are automatically adjusted based on the reading result of the reading device 120, the image adjustment values for the rotation of the image to be printed are adjusted and updated using the correction amount calculated in step S17. The same applies to other skew, trapezoid, and curvature.

(Step S19)
In step S11, if it is determined that the adjustment stop mode has been selected (YES), the control unit 70 does not automatically adjust the image adjustment values of each adjustment item, but sets the formation mode of the image to be printed using the image adjustment values input for each adjustment item.

The image adjustment method for adjusting the formation mode of the image to be printed is completed by the above steps. This image adjustment method may be performed for each sheet of paper during the image formation process when image adjustment values that require adjustment are automatically adjusted in real time. In addition, the method is not limited to this, and may be performed, for example, every time a certain number of sheets of paper are processed, or may be performed only immediately after the start of the image formation process.

During the image formation process, the image forming device main body 110 executes image formation processing of the image to be printed on paper using image adjustment values input by the user and automatically adjusted image adjustment values. For example, the image forming section 40 of the image forming device main body 110 shifts (moves) the image to be printed based on the shift amount input by the user, and rotates the image to be printed based on the image adjustment value for rotation updated by automatic measurement, thereby forming the image to be printed as intended by the user.

As explained above, during image formation processing, for adjustment items that were input by the user before the processing, the input image adjustment values are used preferentially, and the image adjustment values for other adjustment items are updated through automatic measurement. Therefore, the formation mode of the image to be printed can be adjusted as intended by the user.

The above embodiments are merely examples of the implementation of the present invention, and the technical scope of the present invention should not be interpreted in a limiting manner based on them. In other words, the present invention can be implemented in various forms without departing from its gist or main features.
