Description

The present invention relates to an image processing apparatus that makes an image formed on a recording medium invisible.

  2. Description of the Related Art An image processing apparatus (so-called image forming apparatus) that forms an image on a recording medium such as paper using a developer that can be made invisible by erasing is known. The developer used in this image processing apparatus develops a color at a temperature lower than a predetermined value and becomes visible, and loses a color at a temperature equal to or higher than a predetermined value and becomes invisible.

  In addition, an image processing apparatus (so-called image erasure) dedicated to decolorization that heats a sheet on which an image has been formed by the image processing apparatus at a temperature equal to or higher than the predetermined value and decolorizes the image on the sheet by this heating to make it invisible. Device) is known. The paper that has been decolored and rendered invisible can be reused as an image forming paper.

  There is also known a hybrid type image processing apparatus having an invisible function together with an image forming function.

  In such an image processing apparatus, when it is desired to erase (invisible) a set number of sheets, for example, 10 sheets of image-formed sheets, the user sets 10 sheets of image-formed sheets in the sheet feeding cassette or manual feed tray of the apparatus. To do. Then, the user sets the erasing mode and the erasing number “10” on the control panel of the image processing apparatus, and presses the start key in the control panel to start the erasing process by the apparatus.

JP 2012-78808 A

  In an image processing apparatus that performs image processing while transporting paper, a jam often occurs because the paper being transported becomes jammed. When a jam occurs, the image processing apparatus interrupts the processing. Then, the image processing apparatus restarts the process when the jammed paper is removed by the user. The removed paper is often discarded by the user.

  The image processing apparatus continues the processing from the state immediately before the occurrence of the jam, without counting the number of removed papers when the processing associated with the removal of the jammed paper is resumed. For example, if the set number is “10” and the erasing process progresses to 3 sheets and the 4th sheet is jammed and removed, the remaining 7 sheets are fed without counting the 4th sheet. Paper and process it.

  In this case, the number of sheets to be discharged after the erasing process is the same as the set number of sheets, but the number of sheets fed from the paper feed cassette or the manual feed tray is 11 sheets, which is larger than the set number. .

  The fact that a larger number of sheets than the set number is fed means that a sheet different from the first set of image-formed sheets originally exists in the sheet feeding cassette and the manual feed tray.

  When an image forming sheet that does not need to be erased, that is, a blank sheet, is originally present in the paper feed cassette or the manual feed tray, the decoloring of the sheet is a wasteful process and wastes power.

  Even if the paper originally present in the paper feed cassette and the manual feed tray is an image-formed paper, some users may not want to feed more paper than the set number.

  An object of the embodiment is to provide an image processing method capable of avoiding useless sheet feeding after a jam of a recording medium is released.

An image processing apparatus according to a first aspect includes a non-visualization unit, a storage unit, a setting unit, a designation unit, and a control unit. The non-visualization unit performs a non-visualization process on the image on the transported recording medium. The storage unit stores the recording medium conveyed to the non-visualization unit. The counting unit counts the number of recording media conveyed from the storage unit to the non-visualizing unit, including the number of recording media on which a jam has occurred . The setting unit sets the number of recording media on which the de-visualization process is performed. The designation unit accepts a designation for making all the recording media accommodated in the accommodation unit the target of the invisible process. When the number is set by the setting unit, the control unit controls the recording medium to be invisible until the count value in the counting unit reaches the number set by the setting unit. When the designation is performed by the recording unit, the control unit performs control so that all the recording media stored in the storage unit are invisible.

A carriage 4 is disposed on the lower surface side of the document table 2, and an exposure lamp 5 is disposed on the carriage 4.

  The carriage 4 reciprocates along the lower surface of the document table 2. The exposure lamp 5 exposes the document on the document table 2 as the carriage 4 moves forward. A reflected light image generated by this exposure is received by a CCD (Charge Coupled Device) 10 through the reflection mirrors 6, 7, 8 and the zoom lens block 9. The CCD 10 outputs an image signal at a level corresponding to the reflected light image from the original.

  A control panel 11 for setting operating conditions is arranged in the vicinity of the document table 2. The control panel 11 includes a touch panel type liquid crystal display unit 12.

  The exposure unit 20 receives an image signal output from the CCD 10. The exposure unit 20 includes a laser beam B1 corresponding to a yellow image signal, a laser beam B2 corresponding to a magenta image signal, a laser beam B3 corresponding to a cyan image signal, and a laser beam corresponding to a black image signal. B4 is a photosensitive drum 21 that is an image carrier for yellow, a photosensitive drum 22 that is a magenta image carrier, a photosensitive drum 23 that is a cyan image carrier, and a black image carrier. Are emitted toward the photosensitive drum 24.

  The photosensitive drums 21, 22, 23, and 24 are arranged in a substantially horizontal direction at regular intervals. A transfer belt 30 serving as an image carrier is disposed above the photosensitive drums 21, 22, 23, and 24. The transfer belt 30 is wound around a drive roller 31 and a driven roller 32. The transfer belt 30 receives power from the drive roller 31 and rotates counterclockwise.

  Primary transfer rollers 41, 42, 43, and 44 are arranged so as to be vertically movable at positions facing the photosensitive drums 21, 22, 23, and 24, respectively. The primary transfer rollers 41, 42, 43, 44 rotate on the photosensitive drums 21, 22, 23, 24 by rotating the transfer belt 30 against the peripheral surfaces of the photosensitive drums 21, 22, 23, 24. The image is transferred onto the transfer belt 30.

The configuration of the photosensitive drum 21 and its peripheral part is shown in FIG.
Around the photosensitive drum 21, a cleaner 21a, a charge eliminating lamp 21b, a charging unit 21c, and a developing unit 21d are sequentially arranged as developing means. The cleaner 21 a removes the developer remaining on the surface of the photosensitive drum 21. The static elimination lamp 21b removes the charge remaining on the surface of the photosensitive drum 21. The charging unit 21 c charges an electrostatic charge on the surface of the photosensitive drum 21.

  The surface of the photosensitive drum 21 charged by the charging unit 21c receives the laser beam B1 emitted from the exposure unit 20. The laser beam B1 forms an electrostatic latent image on the surface of the photosensitive drum 21. The developing unit 21 d develops the electrostatic latent image on the surface of the photosensitive drum 21 by supplying yellow developer D to the surface of the photosensitive drum 21.

  The peripheral parts of the other photosensitive drums 22, 23, 24 have the same configuration. Therefore, the description is omitted. Magenta, cyan, and black developer D are supplied to the photosensitive drums 22, 23, and 24, respectively.

  Each color developer D develops a visible state at a temperature lower than a predetermined value and becomes invisible when the temperature is higher than a predetermined value. The developer D is a mixture of a decolorable toner and a magnetic carrier. is there. The decolorable toner contains a pigment and a color former. The dye and the color former bind to each other when the environmental temperature is lower than a predetermined value, for example, 120 ° C. By this connection, the color of the pigment becomes visible. Moreover, the said pigment | dye and the said color former cancel a mutual bond, when environmental temperature is more than the said predetermined value. Due to the elimination of this connection, the color of the pigment becomes invisible.

  A plurality of paper feed cassettes 50 are arranged below the exposure unit 20. These paper feed cassettes 50 contain a large number of sheets P, which are recording media of different sizes. Among these paper feed cassettes 50, for example, the uppermost paper feed cassette 50 is also used as a decoloring paper feed cassette for setting the paper Px to be invisible when the invisible mode described later is set.

  Pickup rollers 51 and paper feed rollers 52 are arranged at positions corresponding to these paper feed cassettes 50. Each pickup roller 51 takes out the sheets P and Px in each sheet feeding cassette 50 one by one.

The conveyance path 53 extends to the upper discharge port 56 via the registration roller 54, the driven roller 32, the fixing unit 60, and the discharge roller 55. The paper discharge port 56 faces the paper discharge tray 57.

  A secondary transfer roller 33 is disposed at a position facing the driven roller 32 across the transfer belt 30 and the conveyance path 53. The secondary transfer roller 33 transfers the image transferred to the transfer belt 30 to the paper P fed from the registration roller 54. That is, the secondary transfer roller 33 constitutes a transfer unit together with the transfer belt 30, the drive roller 31, the driven roller 32, and the primary transfer rollers 41, 42, 43, and 44.

  From the end of the conveyance path 53 to the upstream position of the registration roller 54, a conveyance path 70 that reverses the front and back of the sheets P and Px and returns to the conveyance path 53 is disposed. The conveyance path 70 includes paper feed rollers 71, 72, and 73.

  A manual feed tray 74 is detachably disposed on the side wall of the main body 1. A conveyance path 75 is disposed from the manual feed tray 74 to a position upstream of the registration rollers 54 in the conveyance path 53. A pickup roller 76 and a paper feed roller 77 are arranged at a position corresponding to the transport path 75. The pickup roller 76 takes out the sheets on the manual feed tray 74 one by one. The paper feed roller 77 supplies the paper taken out by the pickup roller 76 to the registration roller 54.

  The fixing unit 60 includes a heat roller 61 and a pressure roller 62. The fixing unit 60 heats the conveyed paper P with a heat roller 61 at a first temperature lower than a predetermined value (= 120 ° C.), for example, 100 ° C., so that the image transferred onto the paper P is visible on the paper P. It functions as a fixing means for fixing in a state. Further, the fixing unit 60 heats the conveyed paper Px to be invisible at a second temperature that is equal to or higher than a predetermined value by the heat roller 61, for example, 130 ° C., thereby making the image on the paper Px invisible. It also functions as a decoloring means).

A control circuit of the main body 1 is shown in FIG.
A control panel 11, ROM 81, RAM 82, hard disk drive (HDD) 83, scanning unit 84, image processing unit 85, and process unit 86 are connected to the CPU 80 of the computer.

  As shown in FIG. 4, in addition to the touch panel type liquid crystal display unit 12, the control panel 11 includes a numeric keypad 13, a start key 14, a copy key 15 for setting an image forming mode, a scan key 16 for setting an image reading mode, A decoloring key 17 for setting a non-visualization mode (for decoloring mode setting) is provided.

  The ROM 81 stores various programs for control. The RAM 82 is for storing various data. The hard disk drive 83 is for storing image data. The scanning unit 84 includes the carriage 4, the exposure lamp 5, the reflection mirrors 6, 7 and 8, the zoom lens block 9, and the CCD 10, and optically scans and reads an image of the document on the document table 2. The image processing unit 85 appropriately processes the image read by the scanning unit 84.

  The process unit 86 includes the exposure unit 20, the photosensitive drums 21, 22, 23, and 24, the configuration shown in FIG. 2 around each photosensitive drum, the transfer belt 30, the drive roller 31, the driven roller 32, and the primary transfer rollers 41 and 42. , 43, 44, the secondary transfer roller 33, the conveyance path 53, the fixing unit 60, the conveyance path 70, and the like, and the image processed by the image processing unit 85 is formed on the paper P.

The CPU 80 has the following means (1) to (8) as main functions based on the program in the ROM 81.
(1) A setting unit that sets an image forming mode in which the fixing unit operates according to a pressing operation of the copy key 15 of the control panel 11.

  (2) Setting means for setting a non-visualization mode (hereinafter referred to as a decoloring mode) in which the above-described non-visualizing means is operated according to a pressing operation of the decoloring key 17 of the control panel 11.

  (3) When the paper P or Px being conveyed is jammed, the liquid crystal display unit 12 of the control panel 11 displays a first guidance screen for notifying the occurrence of the jam and notifying the measures necessary for releasing the jam. Jam notification means to do.

  (4) A first control unit that interrupts the operations of the fixing unit and the non-visualizing unit when the paper P and Px being conveyed are jammed, and resumes the interrupted operation as the jam is released.

  (5) In the erasing mode, the number of fed paper sheets Px is counted including the number of jammed sheets, and the operation of the invisible means is performed until the counted value reaches the set number (set number) on the control panel 11. 2nd control means to continue.

  (6) In the color erasing mode, the number of fed paper sheets Px is counted without including the number of jammed sheets, and the operation of the invisible means is continued until the counted value reaches the set number on the control panel 11. 3 control means.

  (7) Fourth control means for displaying a second guidance screen for allowing the user to specify whether or not to include the number of jammed sheets Px in the count when the jam is canceled in the erasing mode.

  (8) Fifth control means for selecting either the control of the second control means or the control of the third control means according to the designation on the second guidance screen.

Next, the control executed by the CPU 80 will be described with reference to the flowchart of FIG.

When the user wants to erase, for example, 10 sheets of paper Px on which images have been formed (also called copied), the 10 sheets of paper Px are set in the uppermost sheet cassette 50. Subsequently, the user presses the erasing key 17 on the control panel 11 to set the erasing mode, and sets the set number “10” corresponding to the number of sheets Px set by the ten key 13 on the control panel 11. Set.

  In the erasing mode, when the start key 14 of the control panel 11 is pressed (YES in step 101), the CPU 80 transfers the sheet Px set in the uppermost sheet cassette 50 to the transport path 53. (Step 102).

  The CPU 80 monitors the transport positions and jams of the papers P and Px in the transport paths 53, 70, and 75 through a number of paper sensors arranged in the transport paths 53, 70, and 75.

  When the CPU 80 detects a jam of the paper Px (YES in Step 103), the CPU 80 displays the first guidance screen shown in FIG. 4 on the liquid crystal display unit 12 of the control panel 11 (Step 104).

  The first guidance screen is necessary to notify the occurrence of a jam “jam occurrence” 12a, similarly to notify the occurrence of a jam “paper jam has occurred” 12b, and to clear the jam. A guide character 12c for “please remove the paper according to the guidance” and an image pattern 12d for notifying where the occurrence position of the jam is indicated by the mark M.

  By viewing this first guidance screen, the user can know that the paper Px to be erased has jammed, how to clear the jam, and the position of the jam. In this case, the paper Px removed by the user is often discarded by the user unless it is very clean.

  When the jam of the paper Px is released by the user's action (YES in Step 105), the CPU 80 displays the second guidance screen shown in FIG. 6 on the liquid crystal display unit 12 of the control panel 11 (Step 106).

  The second guide screen displays the guide character 12e “Jam release” to notify the release of the jam, and inquires whether or not to include the paper Px removed by the user in the count “Include the removed paper in the set number of counts” ? ”,“ Include ”key 12g, and“ not include ”key 12h.

  When the user wants to include the jammed paper Px in the count, the user touches the “include” key 12g. If the user does not want to include the jammed paper Px in the count, the user touches the “not include” key 12h.

  When the “include” key 12g is touched (YES in step 107), the CPU 80 displays the third guidance screen shown in FIG. 7 on the liquid crystal display unit 12 of the control panel 11 (step 108).

  The 3rd guidance screen asks whether or not to continue the erasing job that is the operation of the erasing mode in the guidance character 12e “Jam erasing” to notify the cancellation of the jam “Do you want to continue the erasing job? ? ”,“ YES ”key 12j for designating continuation, and“ NO ”key 12k for designating no continuation.

  When the user wants to continue the decoloring job, the user touches the “YES” key 12j. If the user does not want to continue the decoloring job, the user touches the “NO” key 12k with a finger.

  When the “YES” key 12j is touched (YES in Step 109), the CPU 80 includes the number “1” of the jammed paper Px in the count (Step 110). Subsequently, the CPU 80 determines whether or not the count value has reached the set number “10” (step 111).

  If the count value has not reached the set number (NO in step 111), the CPU 80 resumes feeding the next sheet Px (step 102).

  If the count value has reached the set number “10” (YES in step 111), the CPU 80 displays the fourth guidance screen shown in FIG. 8 on the liquid crystal display unit 12 of the control panel 11 (step 112) and erases the color. End the job.

  The fourth guide screen is a guide character 12m for “decoloring job end” for notifying the end of the decoloring job, a set number display field 12n, a deleted number display field 12o by jam, and a decolored number display field 12p. including. The number of sheets deleted due to jam is the number of sheets Px removed by jamming. The number of sheets that have been decolored is the number of sheets of paper Px that have been decolored and become invisible.

  By viewing this fourth screen, the user can know the set number, the number of deletions due to jamming, and the number of completed erasing.

  In this way, by including the number of jammed sheets Px in the count of the number of erasing processed sheets, only ten sheets Px set in the uppermost sheet cassette 50 can be fed. That is, for example, the image forming paper P existing under the paper Px is not unnecessarily erased. The image forming paper P existing under the paper Px is a white paper that does not need to be erased in the first place.

  Thus, wasteful paper feeding after the jam is released can be avoided, so that power is not consumed wastefully.

  By the way, when the “NO” key 12k on the third guidance screen is touched when inquiring to continue the decoloring job on the third guidance screen (NO in step 109), the CPU 80 does not depend on the count value so far. The erasing job is immediately terminated (step 114). Subsequently, the CPU 80 displays the fourth guidance screen of FIG. 8 on the liquid crystal display unit 12 of the control panel 11 (step 112), and ends the erasing job.

  Further, when the “not include” key 12h on the second guidance screen is touched when making an inquiry on the second guidance screen (NO in step 107), the CPU 80 counts the number of jammed paper Px “1”. Not included (step 116). Subsequently, the CPU 80 determines whether or not the count value has reached the set number “10” (step 111). If the count value has not reached the set number (NO in step 111), the CPU 80 resumes feeding the next sheet Px (step 102).

  Thus, by not including the number of jammed sheets Px in the count of the number of erased sheets, the number of erased sheets becomes the same as the set number.

  Note that when the user wants to erase all the sheets in the uppermost sheet cassette 50, the user designates all sheets in the sheet cassette 50 as objects to be erased by the control panel 11. In this case, the CPU 80 executes a decoloring job for all the sheets in the uppermost sheet cassette 50.

[2] A second embodiment will be described.
The CPU 80 has the following means (11) and (12) instead of (5) and (6) of the first embodiment.
(11) In the erasing mode, on the condition that the position of the jam of the paper Px is a predetermined area, the number of the paper Px to be fed is counted including the number of the jam. Second control means for continuing the operation of the invisible means until the set number of sheets is reached.

(12) In the erasing mode, the number of sheets of paper Px to be fed is counted excluding the number of jams on the condition that the position of the jam of the paper Px is not the predetermined area. Third control means for continuing the operation of the invisible means until the set number of sheets is reached.
Other configurations are the same as those of the first embodiment. Therefore, the description is omitted.

The control executed by the CPU 80 will be described with reference to the flowchart of FIG. Here, control different from that of the first embodiment and related portions will be described.
When the “include” key 12g is touched (YES in step 107), the CPU 80 determines whether or not the position of the jammed paper Px is within a predetermined area (step 201).

  The predetermined area is, for example, the area from the registration roller 54 to the paper discharge outlet 56 in the conveyance path 53 and the entire area of the conveyance path 70 for reversal. These areas are areas where there are many bent paths or a large number of rollers, so that the jammed paper is likely to be relatively damaged.

  When the jam position of the paper Px is in the predetermined area (YES in Step 201), the CPU 80 displays the third guidance screen of FIG. 7 on the liquid crystal display unit 12 of the control panel 11 (Step 108).

  When the “YES” key 12j on the third guidance screen is touched (YES in Step 109), the CPU 80 includes the number of jammed paper Px “1” in the count (Step 110). Subsequently, the CPU 80 determines whether or not the count value has reached the set number “10” (step 111). If the count value has not reached the set number (NO in step 111), the CPU 80 resumes feeding the next sheet Px (step 102).

  When the jam position of the paper Px is not the predetermined area (NO in Step 201), the CPU 80 displays the fifth guide screen shown in FIG. 10 on the liquid crystal display unit 12 of the control panel 11 (Step 202) and jammed paper. The number “1” of Px is not included in the count (step 203).

  The fifth guide screen is a guide character 12e “Jam release” for notifying the release of the jam, and “Removed paper is reset and used for notifying that the removed paper may be reused” It includes the guide character 12q.

  By viewing the fifth guide screen, the user knows that the removed paper Px may be reused, and if the removed paper Px is confirmed and there is no major damage, the user can feed the paper Px in the uppermost stage. Re-set to paper cassette 50. After this resetting, the user presses the start key 14 of the control panel 11.

  When the start key 14 is pressed (YES in step 204), the CPU 80 determines whether or not the count value has reached the set number “10” (step 111). If the count value has not reached the set number (NO in step 111), the CPU 80 resumes feeding the next sheet Px (step 102).

  In this way, whether the jammed paper Px is seriously damaged is judged from the jam position, and in a situation where the damage is not so great, the jammed paper Px is not included in the count, and is reset again, so The usable paper Px can be used effectively. This promotion of reuse can greatly contribute to resource saving.

[3] Modification
The case where the paper Px on which the image has been formed is set in the uppermost sheet cassette 50 and fed is described as an example. However, the setting position and the sheet feeding position are not limited to the uppermost sheet cassette 50. The lower paper feed cassette 50 or the manual feed tray 74 may be used.

  Whether or not to include the jammed paper Px in the count is configured to allow the user to specify on the second guidance screen after the jam release, but the main body 1 has either a mode in which the jammed paper Px is included in the count or a mode in which the jammed paper Px is not included in the count. It is also possible to make initial settings.

  The contents of the guide characters and image patterns displayed on the liquid crystal display unit 12 of the control panel 11 are not limited to the guide characters 12a, 12b... And the image patterns 12d, and various modifications can be made. What is necessary is just to select the content of a guide character or an image pattern suitably according to the culture, language, etc. of the area | region where the main body 1 is installed.

In addition, the said embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment can be implemented in various other forms, and various omissions, rewrites, and changes can be made without departing from the spirit of the invention.
