The sensor unit 18 includes two sensors 18 b provided on the surface of the document table 12. Each sensor 18 b passes a signal indicating whether or not the paper document 100 is covered to the control unit 2. The width of the paper document 100 in the Y direction can be determined depending on which sensor 18b is covered with the paper document 100.

[Image forming equipment]
As shown in FIGS. 1 and 2, the printing apparatus 1 includes an image forming apparatus 20. The image forming apparatus 20 prints an image to be printed on printing paper.

  In the present embodiment, as shown in FIG. 1, the image forming apparatus 20 includes five paper feed trays 22 (paper feed tray (1) to paper feed tray (5)) that store printing paper. . Each paper feed tray 22 corresponds to a “paper storage unit”.

  The paper size of the printing paper that can be stored in each paper feed tray 22 is determined in advance. The storage unit 4 stores a paper size table indicating the paper sizes of printing papers that can be stored in each paper feed tray 22. FIG. 4 is a diagram illustrating an example of a paper size table. The paper size table includes a paper feed tray field and a paper size field. In the paper feed tray field, the tray number of each paper feed tray 22 is stored. The paper size field stores the ID of the paper size that can be stored in the paper feed tray 22 of the tray number in association with the tray number stored in the paper feed tray field. For example, according to FIG. 4, the paper feed tray (1) can accommodate standard size printing paper such as A3 size, A4 size, B4 size, and B3 size. In addition, the paper feed tray (5) can accommodate irregular-size printing paper. In other words, the paper feed tray (5) can accommodate printing paper of any size except for extremely small sizes and extremely large sizes.

  In addition, the storage unit 4 stores an attribute table indicating attributes of each paper feed tray 22. FIG. 5 is a diagram illustrating an example of the attribute table. The attribute table indicates whether each paper feed tray 22 is in failure. That is, the attribute table includes a paper feed tray field and a status field. In the paper feed tray field, the tray number of each paper feed tray 22 is stored. In the status field, a status flag indicating whether or not the paper feed tray 22 of the tray number is in failure is stored in association with the tray number stored in the paper feed tray field. “Failure” indicates that the paper feed tray 22 is in failure, and “Normal” indicates that the paper feed tray 22 is not in failure.

  The attribute table also indicates the quality of the printing paper stored in each paper feed tray 22. That is, the attribute table also includes a paper quality field. In the paper quality field, information indicating the paper quality of the printing paper stored in the paper feed tray 22 of the tray number is stored in association with the tray number stored in the paper feed tray field. In the case of this embodiment, information stored in the paper quality field is input by the user. Note that “thick paper” is not used for duplex printing.

  The attribute table also indicates the paper size of the printing paper stored in each paper feed tray 22. That is, the attribute table also includes a paper size field. In the paper size field, the paper size ID of the printing paper stored in the paper feed tray 22 of the tray number is stored in association with the tray number stored in the paper feed tray field. However, when the paper size of the stored printing paper is not a standard size such as “A4” size, “A3” size, and “B4” size, the width of the printing paper in the main scanning direction and the width in the sub-scanning direction itself Is stored. In the present embodiment, information stored in the paper size field is input by the user. When a sensor for detecting the paper size of the printing paper is provided in each paper feed tray, the paper size detected by each sensor may be stored in the paper size field.

  The attribute table also indicates whether or not each APS (Auto Paper Selection) function is set to be excluded from the application target. That is, the attribute table also includes an application target field. In the application target field, there is an application target flag that indicates whether or not the ATS function is not applied to the paper feed tray 22 of the tray number in association with the tray number stored in the paper feed tray field. Stored. “Not applicable” indicates that a setting that is not applicable to the APS function is made, and “Applicable” indicates that a setting that is not applicable to the APS function is not made. The user operates the operation input unit 6 to appropriately set a desired paper feed tray 22 to be excluded from the application of the APS function, or cancel the setting made on the paper feed tray 22. Or

  As shown in FIGS. 1 and 2, the image forming apparatus 20 includes a plurality of conveyance rollers 24 installed along the sheet conveyance path 25. The conveyance roller 24 is driven in accordance with a command from the control unit 2 and conveys printing paper stored in one of the paper feed trays 22 to an image forming unit 26 described later.

  As shown in FIGS. 1 and 2, the image forming apparatus 20 includes an image forming unit 26 (printing unit). The image forming unit 26 prints the image to be printed on the printing paper conveyed from the conveyance roller 24 in accordance with the instruction of the control unit 2. In the case of the present embodiment, the image forming unit 26 includes a photosensitive drum, a transfer roller, a fixing device, and the like, and a toner image formed on the charged photosensitive drum is transferred to a printing sheet by the transfer roller and fixed. Fix the toner image transferred by the machine. The image forming unit 26 prints the image to be printed on one side of the printing paper when the normal copy execution operation is performed, and prints the image to be printed when the special copy execution operation is performed. Two are printed on both sides of the printing paper. The printing paper is discharged to a discharge tray 28 (see FIG. 1).

[processing]
Next, processing executed by the control unit 2 in accordance with the above program when a copy execution operation is performed will be described. FIG. 6 is a flowchart showing processing executed by the control unit 2 when a copy execution operation is performed.

  First, the control unit 2 specifies the document size of the paper document 100 placed on the document table 12 based on a signal from the sensor unit 18, and specifies the specified document size, the print magnification input by the user, Based on the above, the image size of the image to be printed is calculated in advance (S101). In the present embodiment, the control unit 2 calculates the width in the main scanning direction and the width in the sub-scanning direction of the image to be printed according to a predetermined calculation algorithm.

  Then, based on the calculated image size, the control unit 2 specifies a paper size corresponding to the image size as a recommended size (S102). That is, the control unit 2 specifies the paper size of the printing paper on which the image to be printed is to be printed as a recommended size according to a predetermined algorithm. For example, when the document size of the paper document 100 is “A4” and the print magnification is “100%”, the “A4” size is specified as the recommended size. In S102, the standard size is specified as the recommended size in principle. However, depending on the document size of the paper document 100 (for example, when the paper document 100 is an irregular paper document), the standard size is not specified as the recommended size, and the irregular size is specified as the recommended size. That is, the width in the main scanning direction and the width in the sub scanning direction are specified as the recommended size.

  Then, the control unit 2 (identifying means) reads the paper size table (see FIG. 4) from the storage unit 4 (S103). Then, the control unit 2 (identifying means) refers to the paper size table and selects a paper feed tray 22 that can accommodate printing paper of the recommended size among the paper feed trays (1) to (5). Specify (S104). In the case of the present embodiment, the paper feed tray 22 whose paper size that can be accommodated is “indeterminate” (see FIG. 4) is necessarily specified in S104. When the width in the main scanning direction and the width in the sub-scanning direction are specified as the recommended sizes, only the paper feed tray 22 whose accommodable paper size is “irregular” (see FIG. 4) is specified in S104. Is done.

  And the control part 2 (identification means) reads the attribute table (refer FIG. 5) from the memory | storage part 4 (S105). Then, the control unit 2 (identifying means) refers to the attribute table and identifies the APS target tray (corresponding to the selection candidate accommodating unit) to which the APS function is to be applied among the paper feed trays 22 identified in S104. (S106). That is, when the normal copy execution operation is performed, the control unit 2 executes the process shown in FIG. 7A in S106, and when the special copy execution operation is performed, the control unit 2 performs the process shown in FIG. 7B in S106. Execute.

  First, FIG. 7A will be described. The control unit 2 sorts the paper feed trays 22 identified in S104 in ascending order of tray numbers (S106A). Then, the control unit 2 executes steps S106B, S106C, and S106D in order from the first paper feed tray [1] in the sort order. That is, the control unit 2 refers to the attribute table to determine whether or not the paper feed tray [i] is out of order (S106B). In addition, when the paper feed tray [i] is not out of order (N in S106B), the control unit 2 refers to the attribute table and the paper feed tray [i] is set to be excluded from the application of the APS function. It is determined whether or not (S106C). If the setting for excluding the APS function from being applied to the paper feed tray [i] is made (N in S106C), the control unit 2 sets the tray number of the paper feed tray [i] to the tray of the APS target tray. The number is stored in the storage unit 4 (S106D).

  Note that if the paper feed tray [i] is out of order (Y in S106B), or if the paper feed tray [i] is set to be excluded from the application of the APS function (Y in S106C), control is performed. The unit 2 executes steps subsequent to S106B for the next paper feed tray.

  Next, FIG. 7B will be described. As shown in FIG. 7B, when a special copy execution operation is performed, S106A, S106B, S106C, and S106D are executed in the same manner as when the normal copy execution operation is performed (see FIG. 7A). However, in this case, in addition to these steps, the step of S106a is executed. In S106a, the control unit 2 refers to the attribute table, and the quality of the printing paper stored in the paper feed tray [i] is “thick paper”. It is determined whether or not (S106a). This is because thick paper is not used for duplex printing. The paper feed tray [i] is not in failure (N in S106B), the thick paper is not stored in the paper feed tray [i] (N in S106a), and the paper feed tray [i] If the setting for excluding the application of the APS function is not made (N in S106C), the control unit 2 stores the tray number of the paper feed tray [i] in the storage unit 4 as the tray number of the APS target tray in S106D. To do.

  In this way, the APS target tray is specified. Subsequently, the steps after S107 are executed.

  That is, the control unit 2 reads the tray numbers of all APS target trays stored in the storage unit 4, and sorts the APS target trays in ascending order of the tray numbers (S107). Then, the control unit 2 executes step S108 in order from the first APS target tray [1] in the sort order. That is, in S108, the control unit 2 refers to the attribute table and determines whether or not the paper size of the printing paper stored in the APS target tray [j] matches the recommended size (S108).

  When the paper size of the printing paper stored in the APS target tray [j] does not match the recommended size (N in S108), the control unit 2 executes the step of S108 for the next APS target tray. When there is no APS target tray that accommodates printing paper of the recommended size, step S110 is executed after step S108 is executed for all APS target trays.

  On the other hand, when the paper size of the print paper stored in the APS target tray [j] matches the recommended size (Y in S108), that is, when there is an APS target tray containing the recommended size print paper, The control unit 2 executes step S109 without executing step S110.

  In S109, the control unit 2 executes a copy of the paper document 100 placed on the document table 12 (S109). That is, in step S <b> 109, the control unit 2 drives the ADF unit 14 and sequentially conveys each paper document 100 set on the document table 12 to the image reading unit 16. In step S109, the control unit 2 processes the image signal supplied from the image reading unit 16 based on the print magnification, thereby generating image data for each image to be printed. In step S109, the control unit 2 (printing control unit) drives the conveyance roller 24 to convey the printing paper stored in the APS target tray [j] to the image forming unit 26, and based on the generated image data. Then, the image forming unit 26 is caused to print the image to be printed on the printing paper conveyed from the APS target tray [j]. Here, when the normal copy execution operation is performed, the control unit 2 causes the image forming unit 26 to perform single-sided printing of the image to be printed, and when the special copy execution operation is performed, both sides of the image to be printed are printed. Printing is performed by the image forming unit 26.

  On the other hand, in S110, the control unit 2 (display control means) displays the recommended size and the tray numbers of all APS target trays on the display unit 8 (S110). FIG. 8 is a diagram illustrating an example of the display content of the display unit 8 in S110. The figure described above shows an example of display contents when the recommended size is a standard size, and shows an example of display contents when the recommended size is not a standard size below. As shown in the figure, the recommended size 30 and tray numbers 32 of all APS target trays are displayed on the display unit 8. In the upper diagram, since the recommended size 30 is the standard size, the ID of the recommended size 30 is displayed. In the lower diagram, the recommended size 30 is not the standard size, so the width in the main scanning direction and the width in the sub-scanning direction are It is displayed. The user who refers to the display unit 8 knows that the printing paper of the paper size displayed on the display unit 8 should be stored in the paper feed tray 22 of the tray number displayed on the display unit 8. In the case of this embodiment, the number of lines on the display unit 8 is limited to only four lines. Therefore, the recommended size 30 and the tray number 32 are displayed in one line.

  When a special copy execution operation is performed (when duplex printing is performed), in S110, the control unit 2 determines not only the recommended size and the tray number of all APS target trays, but also paper quality (not used in duplex printing). That is, information indicating “thick paper”) is also displayed on the display unit 8. FIG. 9 is a diagram illustrating an example of display contents of the display unit 8 in S110 when a special copy execution operation is performed. As shown in the figure, the display unit 8 displays a character string 34 indicating thick paper. The user who refers to the display unit 8 knows that printing paper other than the thick paper having the paper size displayed on the display unit 8 should be accommodated in the paper feed tray 22 having the tray number displayed on the display unit 8.

  In addition, embodiment of this invention is not restricted only to the said embodiment.

  For example, as long as it has a function of optically reading the surface of a paper document, any document reading device (for example, a document reading device that does not include the ADF unit 14) is used as the document reading device 10. May be provided.

  For example, the image to be printed is not limited to the image read by the document reading device 10. That is, the present invention is also applicable to printing an image represented by print data (for example, PDL (page description language) data) received from a client device (not shown) or an image stored in advance in the storage unit 4. . In addition, when the printing apparatus 1 includes a FAX receiving device, the present invention can also be applied to printing an image represented by an image signal received by FAX. In this case, an image represented by the print data, an image read from the storage unit 4, and an image represented by the image signal received by FAX correspond to an image to be printed. In this case, the control unit 2 only needs to specify the recommended size from the image to be printed in step S101 (see FIG. 6) and only print the image to be printed in step S109. In this case, the document reader 10 may not necessarily be provided in the printing apparatus 1.

  Further, for example, in S110 (see FIG. 6), the control unit 2 may further display information indicating the print paper storage direction on the display unit 8, thereby guiding the user of the print paper storage direction.

  Further, for example, when there is no paper feed tray 22 that can accommodate printing paper of the recommended size, the control unit 2 displays predetermined error information on the display unit 8 without executing the steps after S105. Also good.

  Further, for example, when there is no paper feed tray 22 serving as the APS target tray, that is, when no tray number of the APS target tray is stored in the storage unit 4, the control unit 2 executes the steps after S 107. Instead, the processing described below may be executed. That is, instead of executing the steps from S107 onward, the control unit 2 determines that the APS target tray is not set as the application target of the APS function among the paper feed trays 22 specified in S104. The tray number of the paper feed tray 22 that has not been displayed may be displayed on the display unit 8. In this case, when the normal copy execution operation is performed, the control unit 2 determines the tray of the paper feed tray [i], for example, when it is determined in S106B of FIG. 7A that the paper feed tray [i] is not in failure. The number is stored in the storage unit 4 as an error display tray number, and the process proceeds to step S106C. When the special copy execution operation is performed, for example, when it is determined in S106a of FIG. 7B that thick paper is stored in the paper feed tray [i], the tray number of the paper feed tray [i] is The error display tray number is stored in the storage unit 4, and the process proceeds to step S106C. If there is no paper feed tray 22 serving as an APS target tray, the control unit 2 displays the error display tray number stored in the storage unit 4 on the display unit 8 instead of executing the steps after S107.
