Description

  The present invention can create a recorded matter by inserting a specific sheet such as a tab sheet in which the order to be conveyed for each sheet is predetermined on a predetermined page set in a plurality of image-recorded sheets. The present invention relates to an image recording apparatus.

  As an image recording device such as a copying machine or a printer, image recording is continuously performed on a plurality of sheets of paper, and an interleaf such as colored paper is automatically applied to a predetermined page of a recorded matter composed of a plurality of sheets of recorded images Some have the ability to insert. In addition, a tab sheet insertion function that feeds tab sheets with tabs protruding from a part of one side of a standard size as a slip sheet from a sheet feed tray different from the sheet feed tray containing plain paper without tabs. Some are provided (for example, see Patent Document 1 or 2).

  The tab sheets are stored in the sheet feeding tray in a state in which a plurality of sets are stacked with a predetermined number (for example, five sheets) obtained by sequentially protruding tabs from a plurality of different positions on one side. In some image recording apparatuses that handle tab sheets as described above, an image such as a headline character is formed on the tab portion of the tab sheet.

  On the other hand, in the conventional image recording apparatus, due to a demand for speeding up of the image recording process, when continuous image recording is performed on a plurality of sheets, there are a plurality of sheets simultaneously in the sheet conveyance path in the apparatus. If any of a plurality of sheets in the sheet conveyance path has a conveyance failure such as a jam, the apparatus displays the occurrence of the conveyance failure and temporarily stops the operation related to the image recording process, and the conveyance of the sheet is also performed. Stopped. When an operator who recognizes the occurrence of conveyance failure removes all the paper existing in the paper conveyance path and instructs the restart of the image recording process by operating the start key or the like, the device exists in the paper conveyance path. The image to be recorded on the first sheet of the plurality of sheets that has been printed is restarted from the image recording process.

For example, as shown in FIG. 8A, consider a case where five sheets P1 to P5 on which images of pages 11 to 15 are to be recorded are simultaneously present in the sheet conveyance path. The first sheet P1 is between the fixing position, the second sheet P2 is between the transfer position and the fixing position, the third sheet P3 is between the transfer position, and the fourth sheet P4 is between the feeding position and the transfer position. When the fifth sheet P5 is in the sheet feeding position, the image recording process is resumed from the process of recording the image of the 11th page on the newly fed sheet. In this way, the image recording apparatus is to perform image recording processing (paper feeding process, transfer process) that should have been performed on a plurality of sheets that existed in the apparatus after the apparatus stopped due to a conveyance failure. , A fixing step and a paper discharge step) are performed on the newly fed paper. This is called jam recovery processing. Therefore, in the example shown in FIG. 8A, the image recording process is performed again for the images that have already been transferred to the sheets P1 and P2 and the image that is being transferred to the sheet P3.
Japanese Patent Application Laid-Open No. 08-245047 JP 2001-302022 A

  Normally, each plain paper is independent of the image to be recorded and the number of pages in the recorded material, and any image can be recorded on each plain paper and can be assigned to any page. For this reason, if only plain paper is present in the apparatus when a conveyance failure occurs, new paper may be sequentially fed in the jam recovery process.

  However, some special papers other than plain paper, such as tab papers, have predetermined images to be recorded on individual papers or pages to be assigned. For example, when a tab sheet is inserted into a plurality of insertion pages in a recorded matter composed of a plurality of pages, the protruding position of the tab on the tab sheet to be inserted into each insertion page is determined in advance.

  For this reason, if there is a tab sheet in the apparatus when the conveyance failure occurs, the tab sheet stored in the sheet feeding unit is sequentially fed in the jam recovery process. There is a problem that a tab sheet to be inserted into the next insertion page is inserted into the insertion page of the tab sheet existing therein, and the recorded matter cannot be properly created.

  For example, as shown in FIG. 8B, among the five sheets P1 to P5 existing in the apparatus when the conveyance failure occurs, the third sheet P3 is the third insertion page in the recorded matter. If it is a tab sheet to be inserted, if jam recovery processing is performed without taking any measures, as shown in FIG. 8C, the third insertion page of the recorded material is inserted into the fourth insertion page. The tab sheet that should be inserted is inserted. For this reason, a tab sheet different from the tab sheet to be originally inserted is inserted into the third and subsequent insertion pages in the recorded matter.

  Such a problem occurs not only when there is a tab sheet in the apparatus at the time of conveyance failure, but also an image to be recorded on each sheet or a page to be allocated is determined in advance and should be conveyed for each sheet. The same occurs when a specific sheet having a predetermined order exists in the apparatus when a conveyance failure occurs. In particular, when the specific paper other than the tab paper is the same size as the other papers constituting the recorded material, the inserted page cannot be distinguished, so that it is difficult to later restore the recorded material to an appropriate state. .

  In addition, when a conveyance failure occurs during image recording processing that continuously records different images on only a plurality of specific papers, if normal jam recovery processing is performed without any treatment, the paper will be An image different from the image to be recorded is formed from the page of the first specific sheet among the specific sheets existing in the conveyance path.

  An object of the present invention is to provide a substitute sheet different from a specific sheet at a timing when the specific sheet should be fed in a subsequent jam recovery process when a specific sheet such as a tab sheet exists in the apparatus when a conveyance failure occurs. It is an object of the present invention to provide an image recording apparatus that can easily produce a recorded matter in an appropriate state even when a conveyance failure occurs.

  The present invention has the following configuration as means for solving the above-described problems.

(1) An image is recorded on a sheet conveyed through a sheet conveyance path formed between the sheet feeding unit via the image recording unit and the sheet discharge unit, and the sheet conveyance failure in the sheet conveyance path In the image recording apparatus that performs a jam recovery process that restarts from the image recording process for the image that should be recorded on the first sheet among the sheets existing in the sheet conveyance path,
In the jam recovery process, when a specific sheet having a predetermined order to be conveyed for each sheet exists in the sheet conveyance path when the conveyance failure occurs, the specific sheet is conveyed during the conveyance of the specific sheet. Instead of this, a different type of substitute paper from the specific paper is conveyed.

  In this configuration, a jam recovery process is performed when a sheet conveyance failure occurs in the sheet conveyance path in a state where a specific sheet having a predetermined order of conveyance for each sheet exists in the sheet conveyance path. At the time of transporting the specific paper, a different type of alternative paper than the specific paper is transported instead of the specific paper. Therefore, in the image recording process after the jam recovery process, the transport order of the specific paper does not change, and the recorded matter is restored to the proper state simply by replacing the substitute paper transported during the jam recovery process with an appropriate specific paper. Is done.

  (2) The jam recovery process is performed when a sheet conveyance failure occurs during continuous image recording processing for only a plurality of the specific sheets.

  In this configuration, a conveyance failure occurs during continuous image recording processing for only a plurality of specific sheets, such as image recording processing in which images of different headline characters are continuously recorded on each tab of a plurality of tab sheets. If this occurs, a plurality of alternative sheets are continuously conveyed in the jam recovery process.

  (3) The jam recovery process is characterized in that the substitute sheet is discharged to a discharge unit in a state where the occupation range in a plan view is not aligned with other sheets.

  In this configuration, the substitute sheet conveyed in place of the specific sheet is aligned with the other sheets in the occupation range in a plan view via, for example, a shift mechanism that changes the discharge position in the direction orthogonal to the conveyance direction. It is discharged to the discharge part in the state that does not. Therefore, the substitute sheet is easily distinguished visually from other sheets in the paper discharge unit.

  (4) The jam recovery process is characterized in that a sheet discharged to the discharge unit in a state where the occupation range in plan view is not aligned with other sheets is fed from the sheet feeding unit as the substitute sheet.

  In this configuration, for example, a sheet discharged to the discharge unit in a state where the storage direction and the sheet size are different and the occupation range in plan view is not aligned with other sheets is conveyed as a substitute sheet. Therefore, the substitute sheet is easily distinguished visually from other sheets in the paper discharge unit.

  (5) In the jam recovery process, an image indicating that the paper is a substitute sheet is recorded on the substitute sheet.

  In this configuration, a substitute sheet on which an image indicating that it is a substitute sheet is recorded is discharged instead of the specific sheet. Therefore, after the image recording process is completed, the work necessary for restoring the recorded matter to an appropriate state is correctly recognized by the display on the substitute sheet.

  (6) The specific sheet is a tab sheet that is stored in the sheet feeding unit in a state where tabs are sequentially projected from each of a plurality of different positions on one side and a predetermined number of sheets are stacked as one set. Features.

  In this configuration, during the image recording process of the recorded matter composed of the sheet including the tab sheet, the tab sheet is replaced in the jam recovery process after the conveyance failure occurs in the state where the tab sheet exists in the sheet conveyance path. The substitute sheet is conveyed. Accordingly, an appropriate tab sheet is inserted after the insertion page after the insertion page into which the tab sheet existing in the sheet conveyance path when the conveyance failure occurs is to be inserted.

  With the above configuration, according to the present invention, the following effects can be obtained.

  (1) A specific sheet in the jam recovery process when a sheet conveyance failure occurs in the sheet conveyance path in a state where the specific sheet having a predetermined order of conveyance for each sheet exists in the sheet conveyance path By transporting an alternative sheet of a different type from the specific sheet instead of the specific sheet at the time of the conveyance, it is possible to prevent the variation of the specific sheet conveyance order in the image recording process after the jam recovery process. As a result, the recorded matter can be easily restored to an appropriate state only by replacing the substitute sheet conveyed during the jam recovery process with an appropriate specific sheet.

  (2) A conveyance failure occurs during continuous image recording processing for only a plurality of specific sheets, such as image recording processing for continuously recording images of different heading characters on each tab of a plurality of tab sheets. In this case, by continuously transporting a plurality of alternative sheets in the jam recovery process, it is possible to prevent a change in the transport order of the specific sheets in the image recording process after the jam recovery process. As a result, the recorded matter can be easily restored to an appropriate state only by replacing the substitute sheet conveyed during the jam recovery process with an appropriate specific sheet.

  (3) The alternative sheet conveyed instead of the specific sheet is in a state where the occupation range in plan view is not aligned with other sheets, for example, via a shift mechanism that changes the discharge position in the direction orthogonal to the conveyance direction. By discharging to the discharge unit, the substitute sheet can be easily distinguished visually from other sheets by the discharge unit. As a result, it is possible to easily perform the work of restoring the recorded matter to an appropriate state.

  (4) For example, in the paper discharge unit, the paper discharged to the discharge unit in a state where the storage direction and the paper size are different and the occupation range in plan view is not aligned with other papers is transferred as a substitute paper. The paper can be easily distinguished from other papers visually. As a result, it is possible to easily perform the work of restoring the recorded matter to an appropriate state.

  (5) By substituting an alternative sheet on which an image indicating that it is an alternative sheet is recorded instead of a specific sheet, after the image recording process is completed, the recorded matter is brought into an appropriate state by displaying on the alternative sheet. The work necessary for the restoration can be recognized accurately, and the work for restoring the recorded matter to an appropriate state can be easily performed.

  (6) Substitute instead of tab paper in jam recovery processing after a conveyance failure occurs in the state where tab paper is present in the paper conveyance path during image recording processing of a recording material composed of paper including tab paper By transporting the paper, it is possible to insert an appropriate tab paper after the insertion page after the insertion page where the tab paper that was present in the paper transport path at the time of the occurrence of transport failure is to be inserted, The recorded matter can be discharged in a state where it can be easily restored.

  FIG. 1 is a diagram showing the configuration of an image recording apparatus according to an embodiment of the present invention. The image recording apparatus 100 includes an image reading unit 110, a paper discharge unit 120, an image recording unit 130, and a paper feed unit 140. The image reading unit 110 reads an image of a document via the exposure units 111a and 111b, the lens 112, and the solid-state image sensor (CCD) 113. The document is conveyed to the upper surface of the document table 115 via the automatic document feeder 114 or manually placed on the upper surface of the document table 116 by rotating the automatic document feeder 114. The CCD 113 outputs a light reception signal of reflected light on the image surface of the document. The received light signal is converted into digital data and supplied to the image recording unit 130 as image data.

  The image recording unit 130 includes a charger 132, a developing unit 133, and a transfer unit 134 around the photosensitive drum 131, and includes an exposure unit 135 and a fixing unit 136, and performs electrophotographic image recording. The image recording unit 130 performs predetermined image processing on the image data supplied from the image reading unit 110 in a control unit (not shown), and the photosensitive drum is driven by image light emitted from the exposure unit 135 based on the image data. The surface of 131 is scanned. The electrostatic latent image formed on the surface of the photosensitive drum 131 by the scanning of the image light is visualized as a developer image by the developer supplied from the developing unit 133. The developer image is transferred onto the sheet fed from the sheet feeding unit 140 by the transfer unit 134. The sheet on which the developer image has been transferred is heated and pressurized in the fixing unit 136, and the developer is melted and fixed on the sheet.

  The paper feed unit 140 includes paper feed trays 141 to 144 and a manual feed tray 145. Each tray 141 to 145 stores a single type and a single size of paper. In the paper feeding unit 140, a paper feeding / conveying path 146 is formed from each of the trays 141 to 145 into the image recording unit 130. Sheets fed one by one from one of the trays 141 to 145 are fed. Paper is fed into the image recording unit 130.

  The paper feed trays 141 and 142 generally store relatively small and frequently used plain paper such as A4 size and B5 size. The paper feed trays 143 and 144 generally store relatively large and low-use plain papers such as A3 size and B4 size. The paper feed tray 143 may store special paper such as matte paper including tab paper. The manual feed tray 145 stores special paper such as paper of a size other than the paper stored in the paper feed trays 141 to 144 and slip sheets including tab sheets.

  The reason why the interleaving paper including the tab sheet is stored in the paper feed tray 143 or the manual feed tray 145 is that a large amount of plain paper frequently used should be stored in the large capacity paper feed trays 141 and 142. Usually, the interleaf sheets fed during the image recording process for a plurality of sheets stored in the paper feed trays 141 and 142 are transported to the image recording unit 130 in response to a request for shortening the image recording process. This is because it should not be stored in the long paper feed tray 144.

  In the image recording unit 130, a main transport path 137, a reverse transport path 138, and a paper discharge transport path 139 are formed. The main transport path 137 extends from the paper feed transport path 146 to the paper discharge transport path 139 between the photosensitive drum 131 and the transfer unit 134 and the fixing unit 136. A paper discharge roller 121 that discharges the paper onto the paper discharge tray 122 of the paper discharge unit 120 is disposed in the paper discharge conveyance path 139. The reverse conveyance path 138 communicates between the paper discharge conveyance path 139 and the paper feed conveyance path 146 of the paper feed unit 140.

  A post-processing device 500 is mounted on one side surface of the image recording apparatus 100. The post-processing apparatus 500 includes a post-processing unit 501 that performs post-processing such as punch hole punching processing and stapling processing on image-recorded paper, and is provided with paper discharge trays 502 and 503.

  The image recording apparatus 100 has a paper reversing function for reversing the front and back surfaces of the paper being conveyed, and a double-sided image recording function for recording images on both sides of the paper using the paper reversing function. The paper discharge roller 121 disposed in the paper discharge conveyance path 139 is rotatable in both forward and reverse directions. The paper discharge roller 121 rotates forward so that the paper can be discharged to the paper discharge tray 122 when the paper is transported to the paper discharge transport path 139 via the main transport path 137. When discharging to 122, normal rotation is continued. When the front and back surfaces of the paper are reversed by the paper reversing function, the paper discharge roller 121 temporarily stops rotating while holding the rear end portion in the conveyance direction of the paper conveyed to the paper discharge conveyance path 139 and then reverses. Rotation is started, and the front and rear ends in the paper transport direction are reversed and guided into the reverse transport path 138.

  During a single-sided image recording process for recording an image on one side of a sheet, the sheet fed from the sheet feeding unit 140 is imaged on one side by the image recording unit 130 while passing through the sheet feeding conveyance path 146 and the main conveyance path 137. After recording, the sheet is discharged to the discharge tray 122 via the discharge conveyance path 139 with the image recording surface facing downward.

  During the double-sided image recording process for recording images on both sides of the paper, the paper fed from the paper feed unit 140 passes through the paper feed conveyance path 146 and the main conveyance path 137 to the first side by the image recording unit 130. After the image is recorded, the front and rear ends in the transport direction are reversed and guided to the reverse transport path 138 by the paper discharge roller 121 that rotates in the reverse direction with the rear end portion in the transport direction of the paper sandwiched. The sheet guided to the reverse conveyance path 138 is opposed to the photosensitive drum 131 with the front and back surfaces reversed while passing through the paper feed conveyance path 146 and the main conveyance path 137, and an image is recorded on the second surface. Thereafter, the paper is discharged to the paper discharge tray 122 via the paper discharge conveyance path 139.

  When post-processing is performed on the image-recorded paper, the paper fed from the paper feed unit 140 or the paper that has passed through the reverse transport path 138 passes through the paper feed transport path 146 and the main transport path 137. After the image is recorded by the image recording unit 130, the front and rear ends in the transport direction are reversed by the paper discharge roller 121 that rotates reversely with the rear end portion in the paper transport direction being sandwiched, and is guided to the post-processing device 180. It is burned.

  In the single-sided image recording process, the paper feed conveyance path 146, the main conveyance path 137, and the paper discharge conveyance path 139 correspond to the paper conveyance path of the present invention. In the double-sided image recording process, the paper feed conveyance path 146, the main conveyance path 137, the reverse conveyance path 138, and the paper discharge conveyance path 139 correspond to the paper conveyance path of the present invention.

  FIG. 2 is a block diagram showing the configuration of the control unit of the image recording apparatus. The control unit 150 of the image recording apparatus 100 includes a document transport system drive circuit 154, an image reading system drive circuit 155, an image recording system drive circuit 156, a paper transport system drive circuit 157, and an image processing circuit. 158 and an operation panel controller 159 are connected.

  The document conveyance system drive circuit 154 drives a document conveyance motor, a clutch, and the like provided in the automatic document feeder 114. The image reading system driving circuit 155 drives a motor, a clutch, and the like for moving the scanning units 111 a and 111 b provided in the image reading unit 110. The image recording system driving circuit 156 drives an image recording motor, a clutch, a high voltage power source, and the like provided in the image recording unit 130. The paper transport system drive circuit 157 drives a motor, a clutch, and the like that are used to rotate a member such as a roller that feeds and transports the paper in the transport paths 137 to 139 and 146. The image processing circuit 158 performs predetermined image processing on the image data read by the image reading unit 110. The operation panel controller 159 detects the operation state of the key 161 provided on the operation panel 160 and displays the setting state of the image recording condition and the operation state of the apparatus on the display 162.

  The CPU 151 operates each of the driving units 154 to 157 and the image processing circuit 158 according to a program written in advance in the ROM 152 in accordance with the setting contents of the image recording condition input from the operation panel controller 159. Data input / output during this time is temporarily stored in the RAM 153. The memory area MA1 of the RAM 153 is assigned to a flag F described later.

  The image recording apparatus 100 includes a tab sheet insertion function for inserting tab sheets into predetermined pages set in advance on a plurality of image-recorded sheets. When the recorded image is created using the tab sheet insertion function, the image recording apparatus 100 uses the operation panel 160 to set a predetermined page on which the tab sheet should be inserted before starting the image recording process, and to set the tab sheet. Accepts selection of a tray to be fed. For example, as shown in FIG. 3A, the tab sheet 200 includes a plurality of sets of five tab sheets 200 (201 to 205) in which tabs are sequentially projected from five different locations on one side. It is stored in the manual feed tray 145 in a stacked state.

  At the time of image recording processing in which the plain paper 300 stored in the state shown in FIG. 3B is fed to the paper feed tray 141 one by one in the direction indicated by the arrow, the manual feed tray 145 is set to a predetermined page position. From FIG. 3A, the tab sheet 200 is fed in the direction indicated by the arrow. As a result, a single or multiple copies of the recorded material 400 in the state shown in FIG.

  As described above, the tab sheet is configured as a set of a predetermined number of tabs protruding from each of a plurality of different positions, each of which is divided by a predetermined number of sides, and is recorded on each tab sheet. The image to be assigned and the page to be assigned are determined in advance.

  FIG. 4 is a flowchart showing the processing procedure of the control unit during the image recording process using the tab sheet insertion function in the image recording apparatus. The control unit 150 of the image recording apparatus 100 resets the flag F assigned to the memory area MA1 of the RAM 153 in the initial setting after power-on (S1), and records an image by operating the start key on the operation panel 160. Waiting for an instruction to start processing (S2).

  The flag F stores a state as to whether or not the paper refeeding process (jam recovery area) of the paper existing in the paper transport path when the paper feeding failure has occurred.

  When the start key is operated, the CPU 151 starts image recording processing (S 2 → S 3) and feeds paper from the paper feed unit 140. At this time, the CPU 151 determines whether or not the sheet to be fed is a tab sheet (S4). If the sheet to be fed is not a tab sheet, the CPU 151 determines from any of the sheet feed trays 141 to 144. Plain paper is fed (S5).

  If the sheet to be fed is a tab sheet, the CPU 151 determines whether or not the flag F is set (S6). If F is in the reset state, tab sheets are fed from a predetermined tray such as the manual feed tray 145 (S7).

  Thereafter, the CPU 151 determines whether or not the paper feed process is in the jam recovery area (S8), determines whether or not a conveyance failure (jam) has occurred (S9), and whether there is next image data. A determination is made as to whether or not (S10), and unless there is a conveyance failure, the processing of S3 to S10 is repeatedly executed until there is no image data, thereby creating a recorded matter in which tab sheets are inserted on predetermined pages of a plurality of plain papers. To do.

  When it is detected that any of the sheets being conveyed has a conveyance failure, the CPU 151 immediately stops the sheet feeding operation, the image recording operation, and the sheet conveying operation (S9 → S13). The CPU 151 determines whether there is a tab sheet among the plurality of sheets stopped in the sheet conveyance path (S14). If a tab sheet exists in the sheet conveyance path, F is set (S15).

  The CPU 151 sequentially updates and stores the type and the current transport position of at least the paper being transported in the paper transport path, and refers to the stored contents to transport the paper when a transport failure occurs. It can be confirmed whether or not a tab sheet exists in the road.

  Thereafter, the CPU 151 waits for completion of the jam clearing work by the worker (S16). For example, when the CPU 151 determines that the jam clearing operation is completed by detecting that the front cover of the image recording apparatus 100 is once opened and then closed, there is no stopped paper in the paper conveyance path. Detection (jam check) is performed (S17), and when there is no stopped paper in the paper conveyance path, the image recording process is resumed (S18 → S3).

  In the image recording process restarted after the occurrence of the conveyance failure, if the flag F is set at the timing of feeding the tab paper, the CPU 151 feeds the substitute paper without feeding the tab paper (S4 → S6). → S11). In other words, the CPU 151 feeds alternative sheets instead of tab sheets when refeeding tab sheets existing in the sheet conveyance path when a conveyance failure occurs. The CPU 151 resets the flag F when the paper re-feeding for the paper existing in the paper transport path when the transport failure occurs is completed (S12).

  Through the above processing, at the time of the image recording process for creating the recorded matter illustrated in FIG. 3, five sheets P1 to P1 including the third tab sheet 203 in the sheet conveyance path of the image recording apparatus 100 as shown in FIG. When a paper conveyance failure occurs in the presence of P5, a substitute sheet is fed instead of the tab sheet when the sheet P3, which is the tab sheet 200, is fed again. For this reason, the fourth tab sheet 204 is not inserted into the third insertion page in the recorded matter, and an appropriate tab sheet 200 (204, 205,... Is inserted into the fourth and subsequent insertion pages in the recorded matter. ) Is inserted.

  As an example, as illustrated in FIG. 6, an alternative sheet 500 that is fed instead of the tab sheet 200 is a sheet that is fed as the plain sheet 300 during the image recording process among the trays 141 to 145 of the sheet feeding unit 140. Paper is fed from a tray other than the paper feed tray stored and the manual feed tray 145 storing the tab paper 200. For example, when the recorded matter 400 created in the image recording process is composed of the vertically long A4 size plain paper 300 and the tab paper 200, the horizontally long A4R size plain paper is used as the substitute paper 500 as shown in FIG. Paper is fed.

  As a result, the substitute sheet 500 is discharged to the paper discharge tray 122 in a state in which the occupation range in plan view is not aligned with other sheets, so that the operator can replace the substitute paper 500 in the recorded matter 400 discharged to the paper discharge tray 122. The insertion and the insertion position of the substitute paper 500 can be easily recognized, and the repair work of the recorded matter 400 by exchanging with the appropriate tab paper 200 can be easily performed.

  Note that, as shown in FIG. 7, an image of a message indicating that a sheet different from an appropriate sheet has been conveyed due to the occurrence of conveyance failure can be recorded on the substitute sheet 500 and discharged. As a result, the operator can accurately recognize the necessity of the work of repairing the recorded matter 400. In the example illustrated in FIG. 7, an image indicating the model name and the use date and time of the alternative paper 500 is recorded in addition to the above message.

  In the above example, as the substitute paper 500, a paper having the same size as that of the paper constituting the recorded matter 400 and conveyed in the longitudinal direction is used. However, a paper having a size larger than that of the paper constituting the recorded matter 400 is used. It can also be used. In addition, the substitute paper 500 that is transported in the same direction in the same size as the paper constituting the recorded matter 400 is displaced to a position perpendicular to the transport direction with respect to the discharge position of the paper constituting the recorded matter 400. You may make it discharge | emit.

  Further, in the image recording apparatus 100, there may be an image recording process in which only a plurality of tab sheets 200 are continuously fed and different images such as heading characters are recorded on each tab sheet 200 in some cases. The present invention can be similarly carried out during the image recording process for only a plurality of specific sheets.

  Furthermore, the present invention can be similarly applied to an image recording apparatus that performs an image recording process for a recorded matter including a specific sheet other than a tab sheet.
