An embodiment of the present invention will be described with reference to the drawings.
(Internal structure of MFP)
FIG. 1 is a schematic diagram illustrating an internal configuration of a multifunction machine 1 (an example of an image forming apparatus with a scanner). The multifunction device 1 has a configuration in which an image forming apparatus main body 3 (an example of an image forming apparatus) and a scanner unit 5 are connected to be communicable by wire or wirelessly.

(1) Image Forming Apparatus Main Body The bottom of the image forming apparatus main body 3 is provided with a plurality of (for example, four) trays T (an example of a storage unit) for storing sheets 7 (for example, paper) for image formation. It has been. Hereinafter, the first tray T1, the second tray T2, the third tray T3, and the fourth tray T4 are referred to in order from the top.

  The sheets 7 stored in the tray T are taken out one by one by the pickup roller 9 and conveyed to the registration roller 11. The conveyed sheet 7 is sent out onto the conveying belt 13 at a predetermined timing while the posture is adjusted by the registration roller 11. The fed sheet 7 is conveyed by the conveying belt 13 and an image (monochrome image, color image) based on the document image data read by the scanner unit 5 is formed by the image forming unit 15.

  The sheet 7 on which the image is formed is heat-fixed while being sandwiched between the heating roller 19 and the pressing roller 21 of the fixing device 17 and is discharged onto the discharge tray 23. Each tray T is provided with a detection sensor 25, and each detection sensor 25 outputs a detection signal corresponding to the size of the sheet 7 stored in the corresponding tray T. The size of the sheet 7 here refers to the width (dimension in the direction orthogonal to the conveyance direction of the sheet 7) and the length (dimension in the conveyance direction of the sheet 7).

  An example of a method for detecting the size of the sheet 7 is as follows. For example, a guide plate (not shown) is provided on the tray T so as to be movable in the width (length) direction of the sheet 7, and the detection sensor 25 outputs a detection signal corresponding to the position of the guide plate. To do. A sheet 7 having a size on the tray T is arranged, and the guide plate is moved to a position where the sheet 7 comes into contact with the sheet 7. Accordingly, the size of the sheet 7 stored in the tray T can be grasped based on the detection signal output from the detection sensor 25.

(2) Scanner Unit The scanner unit 5 reads an image (original image) of the original 31 and outputs original image data, and is provided above the discharge tray 23. The scanner unit 5 is provided with a document cover 35 that can be opened and closed on a document table 33, and a document tray 37 and a feed mechanism 39 are provided on the document cover 35.

  As a method of reading a document image by the scanner unit 5, document placement reading and document feed reading are possible. In the case of document placement reading, when the user places the document 31 on the document table 33, closes the document cover 35, and instructs to read the document, the scanner head 41 moves to read the document image of the document 31 and move the document image. Data is generated and transmitted to the image forming apparatus main body 3. In the case of document feed reading, when the user sets the document 31 on the document tray 37 and instructs to scan the document, the document 31 is conveyed one page at a time into the reading area of the scanner head 41 by the feed mechanism 39, and then the document is discharged. It is discharged to the tray 43. The scanner head 41 reads a document image from the document 31 being conveyed, generates document image data, and transmits it to the image forming apparatus main body 3.

  Here, the scanner unit 5 of the present embodiment does not include a means for uniquely detecting the width of the document 31 set on the document tray 37 (the dimension in the direction orthogonal to the conveyance direction of the document 31). For this reason, the scanner unit 5 itself cannot determine the reading width of the document 31 (the width at which the image reading should be validated by the scanner head 41), and it is necessary to have the reading width specified from the outside. In the present embodiment, as will be described later, the image forming apparatus main body is configured to designate the reading width.

(Electric configuration of the multifunction device)
FIG. 2 is a block diagram illustrating an electrical configuration of the multifunction machine 1. The multi-function device 1 includes a CPU 51 (an example of an acquisition unit, a specification unit, a selection unit, a storage unit specification reception unit, a sheet width specification reception unit), a ROM 53, a RAM 55, an NVRAM 57 (nonvolatile memory), an operation unit 59, a display unit 61, An image forming unit 15, a scanner unit 5, a detection sensor 25, a network interface 63, and a facsimile interface 65 are provided.

  The ROM 53 stores a program for executing various operations of the multi function device 1 such as copy processing described later. The CPU 51 stores the processing result in an internal memory (RAM 55 or NVRAM 57) according to the program read from the ROM 53. ), Each part is controlled.

  The operation unit 59 includes a plurality of buttons, and various input operations can be performed by the user. The display unit 61 includes a liquid crystal display, a lamp, and the like, and can display various setting screens and operation states of the apparatus. The network interface 63 is connected to an external computer (not shown) or the like via a network line, thereby enabling mutual data communication. The facsimile interface 65 is connected to another external device (not shown) having a facsimile function via a public telephone network, thereby enabling mutual facsimile communication.

(Tray and size information)
3A and 3B are a first example of a tray setting table and a sheet width table, and FIGS. 4A and 4B are a second example of a tray setting table and a sheet width table. The first example is a case where the letter size sheet 7 is stored in the first tray T1 and the second tray T2, and the legal size sheet 7 is stored in the third tray T3 and the fourth tray T4. In the second example, the letter size sheet 7 is stored in the first tray T1, the legal size sheet 7 is stored in the second tray T2, the regular A4 size sheet 7 is stored in the third tray T3, A regular A5 size sheet 7 is horizontally stored in the tray T4. Here, “laterally” means a storing direction in which the short direction of the sheet 7 is along the conveying direction.

  When the sheet 7 is set in each tray T and the multifunction device 1 is turned on, the CPU 51 receives the detection signal from each detection sensor 25 described above, and obtains size information of the sheet 7 stored in each tray T. get. At this time, the CPU 51 functions as an “acquisition unit”.

  When acquiring the size information, the CPU 51 generates a tray setting table and stores it in the internal memory. The tray setting table includes information indicating the correspondence between each tray T, size information, and sheet width (see FIGS. 3A and 4A). Next, the CPU 51 refers to the tray setting table, groups the four trays T for each sheet width, generates a sheet width table, and stores it in the internal memory. The sheet width table includes information indicating the correspondence between the group, the tray T, and the sheet width (FIGS. 3B and 4B).

  In the first example, since the sheet widths of the trays T match, all the trays T belong to the group 1. In the second example, since the sheet widths do not match between the trays T, the first tray T1 and the second tray T2 belong to the group 1, and the third tray T3 and the fourth tray T4 belong to the group 2. For example, when the user changes the size or the storage direction of the sheet 7 stored in a certain tray T and, as a result, the sheet width changes, the CPU 51 determines the contents of the tray setting table based on the new sheet width. And the contents of the sheet width table are updated accordingly.

  The internal memory stores a priority table indicating the priority order of the four trays. The CPU 51 generates or updates the priority order table based on, for example, an input operation on the operation unit 59 by the user. Further, for example, the priority order may be updated at any time according to the usage frequency of each tray T. For example, the higher the usage frequency, the higher the priority.

(Copy process)
Next, a copy process executed by the CPU 51 will be described.
(1) Copy Mode Selection The multi-function device 1 can execute “copy mode”, “facsimile mode”, “PC printing mode”, “network transmission mode”, and the like. The copy mode is for copying the original image read by the scanner unit 5 onto the sheet 7, and the facsimile mode is for exchanging facsimile data with the external device. The PC print mode forms an image on the sheet 7 based on the print data received from the external computer, and the network transmission mode sends the document image data generated by the scanner unit 5 to the external device via the network line. To send to. In this network transmission mode, the document image data may be attached to a mail or the like and transmitted to an external device. The user can instruct execution by selecting one of the plurality of modes by operating the operation unit 59.

  The CPU 51 executes the following copy process only when the copy mode is selected from the plurality of modes, and does not execute any mode other than the copy mode (when the non-copy mode is selected).

(2) Tray Selection FIG. 5 is a simplified diagram showing a tray selection screen in the first example, and FIG. 6 is a simplified diagram showing a tray selection screen in the second example. When the copy mode is selected, the CPU 51 causes the display unit 61 to display a tray selection screen as one of various setting screens. On the tray selection screen, it is possible to select from “no width limitation mode”, “width limitation mode”, and “user designation mode”. At this time, the CPU 51 functions as a “storage unit designation receiving unit, sheet width designation receiving unit”. These mode designations may be performed by, for example, the external computer, and the CPU 51 may accept the designation information.

  The no width limitation mode determines the reading width without being limited to the selection of the sheet width by the user, and can be selected by designating a “no width limitation mode” button on the tray selection screen. The width limitation mode is for determining the reading width based on the sheet width (group) selected by the user, and can be selected by designating a “group” button on the tray selection screen. The width no-designation mode is a mode that can be suitably used when a plurality of documents 31 having a fixed document width and different document lengths are mixedly loaded on the document tray 37 and copied. In the user designation mode, the reading width is determined based on the sheet width corresponding to the tray selected by the user, and can be selected by designating a “tray” button on the tray selection screen. In FIGS. 5 and 6, the mode of the button that is blacked out means a mode that is currently selected, and in this embodiment, the mode with no width limitation is selected as a default.

(3) Document Reading Process and Reading Width Determination Process FIG. 7 is a flowchart showing the document reading process, and FIG. 8 is a flowchart showing the reading width determination process. When the user selects one of the modes on the tray selection screen and performs a copy mode execution confirmation operation, the CPU 51 executes a document reading process. At this time, the CPU 51 functions as a “designating unit”.

  First, a reading width determination process is executed (S101). In the reading width determination process, the processing contents differ depending on whether the width limitation mode, the width limitation mode, or the user designation mode is selected on the tray selection screen. Hereinafter, the case where each is selected is demonstrated individually.

(3-1) When No Width Restriction Mode is Selected When the no width limitation mode is selected (S201: YES), the CPU 51 refers to the sheet width table and there are a plurality of the groups of the tray T. Whether or not (S203). If there is only one group (in the case of the first example) (S203: NO), the reading width (for example, substantially the same as the sheet width) is determined based on the sheet width corresponding to the one group ( S205).

  Specifically, the reading width is determined based on the sheet width and the reading magnification designated when the copy mode execution instruction is given. For example, in the first example, if the reading magnification is 1, the sheet width (8.5 inches) of the first group is determined as the reading width. If the reading magnification is double, a width approximately half of the sheet width is determined as a reading width (in short, a value obtained by dividing the sheet width by the reading magnification). Then, the reading width determination process ends, and the process proceeds to S103 in FIG.

  On the other hand, when there are a plurality of groups (in the case of the second example) (S203: YES), for example, a designation method selection screen (not shown) is displayed on the display unit. On the designation method selection screen, any of the designation methods of “majority designation”, “priority designation”, and “no designation” can be selected by the user's operation on the operation unit 59. Note that the user may select a designation method in advance when selecting the tray.

  The majority decision is a method of determining the reading width based on the sheet width that matches the most trays T, in other words, the sheet width corresponding to the group to which the most trays T belong (hereinafter referred to as the maximum group). . If the majority decision is selected (S207: YES), it is determined whether a majority decision is possible with reference to the sheet width table (S209).

  When only one maximum group can be specified from a plurality of groups, it is determined that majority determination is possible (S209: YES), and the reading width is determined based on the sheet width corresponding to the maximum group (S211), The reading width determination process ends, and the process proceeds to S103 in FIG. If the reading width is determined in this way, the possibility that the original image formed on the sheet 7 is missing can be reduced.

  On the other hand, if only one maximum group cannot be specified, it is determined that the majority decision is impossible (S209: NO), and the same processing as that in the case of specifying no designation described later is performed (S213). For example, in the second example, since the number of trays T belonging to each of the first group and the second group is the same, it is determined that the majority decision is impossible. In addition, when majority decision is impossible, the structure which transfers to the priority designation | designated described below may be sufficient.

  If priority order designation is selected (S207: NO and S215: YES), the reading width is determined based on the sheet width corresponding to the uppermost tray T with reference to the priority order table (see FIG. S217). Then, the reading width determination process ends, and the process proceeds to S103 in FIG.

  When “None” is selected (S207: NO and S215: NO), the maximum sheet width (hereinafter referred to as “sheet width”) among all the sheet widths corresponding to the tray T is referred to the priority order table. The maximum sheet width is extracted, and the reading width is determined based on the maximum sheet width (S213). Then, the reading width determination process ends, and the process proceeds to S103 in FIG. If the reading width is determined based on the maximum sheet width in this way, at least the problem that the original image formed on the sheet 7 is missing during reading can be suppressed.

(3-2) When the mode with width limitation is selected When the mode with width limitation is selected (S201: NO and S219: YES), the CPU 51 refers to the sheet width table, and the tray The reading width is determined based on the sheet width corresponding to the group selected on the selection screen (S221). Then, the reading width determination process ends, and the process proceeds to S103 in FIG.

(3-3) When the User Designation Mode is Selected When the user designation mode is selected (S201: NO and S219: NO), the CPU 51 refers to the tray setting table and displays the tray selection screen. The reading width is determined based on the sheet width corresponding to the tray T selected in (S223). Then, the reading width determination process ends, and the process proceeds to S103 in FIG.

  In S <b> 103 of FIG. 7, the CPU 51 designates the reading width determined in the reading width determination process to the scanner unit 5. As a result, the scanner unit 5 can read a document. If the internal memory has a free space of a predetermined amount or more (S105: YES), the CPU 51 instructs the scanner unit 5 to read a document (S107). Then, the scanner unit 5 reads the document image within the specified reading width, generates document image data, and transmits it to the image forming apparatus main body 3.

  Then, the CPU 51 receives the document image data and temporarily stores it in the internal memory together with the reading width and the number of reading lines (S109). The number of lines actually read by the scanner unit 5 in the image reading process is transmitted to the image forming apparatus body 3, and the CPU 51 acquires the number of transmitted lines as the number of read lines. Further, the CPU 51 may obtain the reading width from the size information of the selected group or tray T.

  For example, if there is a document on the next page in the document feed reading (S111: YES), the process returns to S105, and the processing from S105 to S109 is repeated for the document on the next page. On the other hand, if there is no document on the next page (S111: NO), a final page flag is added to the last received document image data (S113), and the document reading process is terminated.

(4) Image Forming Process FIG. 9 is a flowchart showing the image forming process. When the original image data is stored in the internal memory (S301: YES), the CPU 51 obtains an image size (size obtained by multiplying the original image by the reading magnification) based on the reading width and the number of reading lines. Then, referring to the tray setting table, the tray T (appropriate tray T) that stores the sheet 7 suitable for the image size (in other words, the sheet 7 having a size close to the image size) is selected (S303). At this time, the CPU 51 functions as a “selection unit”. Note that the CPU 51 may select the tray T only from the number of reading lines.

  Here, if there is one appropriate tray T (S305: NO), that one tray T is selected and the process proceeds to S309. However, for example, as in the first example, when there are a plurality of trays T storing sheets of the same size (S305: YES), the order is selected from a plurality of appropriate trays T with reference to the priority table. Selects the upper tray T and proceeds to S309.

  Then, the CPU 51 instructs the image forming unit 15 to execute image formation on the sheet 7 based on the document image data (S309), and thereafter deletes the document image data from the internal memory (S311). If the last page flag is not added to the document image data that has undergone the last image formation processing (S313: NO), the process returns to S301, and if the last page flag is added (S313: YES), the main image formation is performed. End the process.

(Effect of this embodiment)
According to the present embodiment, the reading width of the document 31 in the scanner unit 5 is determined based on the size information of the sheet 7 stored in the tray T. Since the image of the document 31 is finally formed on the sheet 7 from the tray T, the document size often corresponds (proportional) to the size of the sheet 7 stored in the tray T. Therefore, by specifying the determined reading width to the scanner unit 5, the scanner unit 5 can read the document 31 while suppressing problems such as extra image reading and missing document images.

  Further, an appropriate tray T can be automatically selected based on the reading width and the number of reading lines. In addition, since the number of reading lines is taken into account, for example, even when letter size and legal size documents 31 are mixedly loaded on the document tray 37 and document feeding reading is executed, an appropriate tray T is individually provided for each document image. It is possible to select automatically.

  In addition, the automatic mode (the mode without width limitation, the mode with a width limitation) and the manual mode (user specified mode) can be selectively executed according to various situations.

  In this embodiment, the reading width determination process is performed when the copy mode is executed, and is not performed when the non-copy mode is executed. Accordingly, unnecessary determination processing can be suppressed by performing the determination processing in the copy mode in which the reading width is often not designated in advance.
