Description

  The present invention relates to a copying machine and a storage medium for storing a program for the copying machine. More specifically, the present invention relates to a copying machine having a scaling function for enlarging or reducing an original image.

  2. Description of the Related Art Conventionally, a copying machine having a scaling function for enlarging or reducing an original image has been put into practical use. In addition, as a technology for setting the scaling function, a technology for selecting a magnification from a standard size to a standard size, and a technology for displaying a magnification from a standard size to a standard size as a guide for setting the magnification by the user are known. It has been.

  For example, Patent Document 1 discloses a technique that discloses a technique related to setting of a scaling function. Japanese Patent Application Laid-Open No. 2004-228561 discloses a configuration in which a copying machine having a scaling function displays an icon that can determine the magnitude relationship between the size of an original and the size of an output sheet on a screen for setting a magnification.

Japanese Patent Laid-Open No. 11-177741

  However, the conventional technique described above has the following problems. That is, if the number of magnification options is increased in order to cope with many standard sizes, it takes time for the user to find a desired magnification. On the other hand, if the displayed options are limited to a magnification that is generally used frequently, a user may not be able to select a desired magnification, which is inconvenient.

  The present invention has been made to solve the above-described problems of the prior art. That is, the problem is to provide a technology that is a copying machine having a scaling function and that can be expected to facilitate the setting of the magnification.

  In order to solve this problem, a copying machine includes a reading unit that reads an image of a document, a printing unit that prints an image on a sheet, a tray that accommodates a sheet to be printed on the printing unit, a display unit, and a control unit. A control unit for acquiring a size of a sheet accommodated in the tray, and a magnification selection screen that is a screen for selecting a magnification, and the sheet acquired in the acquisition process. Display processing for causing the display unit to display the magnification selection screen that displays, as an option, a specific sheet magnification that is a magnification obtained from the combination of the acquired sheet size and the standard size of the document. , Enlargement / reduction of the image of the original read by the reading unit based on the magnification selected via the magnification selection screen, and printing on the printing unit It is characterized in that the run.

  The copying machine disclosed in this specification accepts the setting of the magnification on the magnification selection screen when using the scaling function. The copying machine obtains the size of the sheet stored in the tray in advance, and the magnification obtained from the combination of the obtained sheet size and the standard size that can be the document size on the magnification selection screen. The specific sheet magnification is displayed as an option. That is, the copying machine does not select a magnification that does not match the size of the sheets stored in the tray. Thereby, for example, the number of options can be reduced as compared with the case where the magnifications of all combinations of standard sizes are used as options. Even if the number of options is reduced, the magnification that the size of the sheet contained in the tray is used as the size of the sheet to be printed is used as an option. Easy to use.

  In the display process, when the number of the specific sheet magnifications is smaller than a predetermined number, the control unit includes all the specific sheet magnifications as options, and the number of the specific sheet magnifications is smaller than the predetermined number. If there is not, a classification selection screen for selecting enlargement or reduction is displayed on the display unit, and all the specific sheets corresponding to either enlargement or reduction are displayed using the selection result on the classification selection screen. The magnification may be included in the options. As the number of specific sheet magnifications increases, the number of options that can be selected on the magnification selection screen increases, and it takes time for the user to find a desired magnification. Therefore, when the number of specific sheet magnifications is large, further enlargement or reduction is selected, and a specific sheet magnification corresponding to one of them is displayed as an option according to the selection result, thereby making it easy to find a target magnification.

  Further, the copying machine disclosed in the present specification includes a size sensor that outputs a different signal according to the size of the sheet stored in the tray, and the control unit receives the signal from the size sensor in the acquisition process. The size of the sheet stored in the tray may be acquired based on the output signal. By measuring the size of the sheet, a size with higher reliability than the size obtained by user input can be obtained.

  The copying machine disclosed in this specification includes a plurality of trays, and the control unit acquires a sheet size for each tray in the acquisition process, and a plurality of trays in the acquisition process in the display process. When the size of the document is acquired, a size selection screen for selecting a size to be printed from the sizes is displayed on the display unit, and a combination of the standard size of the document and the size selected via the size selection screen is displayed. The magnification determined from the above is preferably the specific sheet magnification. When a plurality of sizes are acquired, if the magnification corresponding to all the acquired sizes is the specific sheet magnification, there are too many options and it is difficult to find a desired magnification. For this reason, the user can select the sheet size, and the increase in the number of options can be expected by setting the specific sheet magnification to a magnification suitable for the selected sheet size.

  Further, in the acquisition process, the control unit may exclude a sheet size based on a tray in which no sheet is stored, from the sheet size candidates selected on the size selection screen. Even if a sheet size corresponding to a tray that does not contain sheets is selected as an option, the possibility of being selected is low. Therefore, it is preferable to exclude it from the options.

  Further, the copying machine disclosed in this specification includes a storage unit, and when the magnification is selected via the magnification selection screen, the control unit is a document that is information regarding the size of the document based on the magnification. A storage process for storing information in the storage unit, a determination process for determining whether or not a size of a print target sheet has been changed, and a determination that the size of a print target sheet has been changed in the determination process In addition, the display unit displays the magnification selection screen that displays, as an option, a specific document magnification that is a magnification obtained from a combination of a size specified by the document information stored in the storage unit and a standard sheet size. It is recommended to execute the change display process. The document information may be the document size itself or a combination of the magnification and the sheet size. Since the copying machine acquires the sheet size, the size of the document can be estimated by selecting the magnification. For this reason, the copying machine stores document information related to the size of the document after the magnification is selected, and when the sheet size is changed after that, from the size obtained from the document information, various standard sizes of sheets and By displaying various magnifications as options on the magnification selection screen, it is highly possible that a magnification suitable for the document is displayed as an option, which is easy to use.

  Further, the copying machine disclosed in this specification includes a tray sensor that outputs a different signal depending on whether or not the tray is set in the apparatus, and the control unit uses the tray sensor in the determination process. When it is determined that the tray setting state has changed, it may be determined that the size of the sheet to be printed has been changed. When the set state of the tray changes, that is, when the tray is opened, the possibility that the user has changed the sheet is increased. Therefore, it is preferable to determine that the size of the sheet to be printed has been changed.

  Further, the copying machine disclosed in this specification includes a plurality of trays, and the control unit determines that the size of the sheet to be printed has been changed when the change of the tray to be used is received in the determination process. It is good to judge. There is a possibility that different types of sheets are accommodated in each tray, and when the tray to be used is changed, the possibility that the size of the sheet is changed increases. Therefore, it is preferable to determine that the size of the sheet to be printed has been changed.

  The control unit may display a magnification corresponding to the size acquired in the acquisition process after the size of the sheet to be printed is changed among the specific document magnifications with priority over other magnifications. Good. When the sheet size is obtained, it is most likely that a magnification that matches the size is selected. Therefore, it is preferable to display the magnification with priority over other magnifications.

  A control method for realizing the functions of the copying machine, a computer program, and a computer-readable storage medium storing the computer program are also new and useful.

  According to the present invention, it is possible to realize a technique that can be expected to facilitate the setting of a magnification, which is a copying machine having a scaling function.

In the present embodiment, the present invention is applied to a multi function peripheral (MFP) having an image reading function and an image forming function.

[MFP configuration]
As shown in FIG. 1, the MFP 100 of this embodiment includes an image forming unit 1 that prints an image on a sheet and an image reading unit 2 that reads an image of a document. The image forming method of the image forming unit 1 may be an electrophotographic method or an ink jet method. Further, even if a color image can be formed, it may be dedicated to a monochrome image. The image reading unit 2 may be capable of reading a color image or may be dedicated for monochrome reading. The image forming unit 1 is an example of a printing unit.

  The image reading unit 2 includes a main body unit 10 that reads an image and an automatic document feeder (ADF) 20 that automatically conveys a document. The ADF 20 is positioned above the main body 10 and has one side connected to the main body 10 so as to be rotatable with respect to the main body 10. Therefore, the image reading unit 2 can open and close the upper surface of the main body unit 10 by the ADF 20. That is, the ADF 20 also serves as a cover that covers the upper surface of the main body 10. FIG. 1 shows a state in which the ADF 20 is closed. The main body 10 of the image reading unit 2 is an example of a reading unit.

  The image forming unit 1 also includes paper feed trays 91 and 92 that store sheets before the image is printed by the image forming unit 1 and paper discharge that stores sheets after the image is printed by the image forming unit 1. A tray 95. Each of the paper feed trays 91 and 92 can be detached from the image forming unit 1. In this embodiment, the state in which the paper feed tray is attached to the image forming unit 1 is the state in which the paper feed tray is set, and the state in which the paper feed tray is removed from the image forming unit 1 is not set. State. Further, it is sufficient that at least one sheet feeding tray is provided, and the number is not limited to two as shown in FIG. The paper feed trays 91 and 92 are examples of trays.

  Further, MFP 100 includes an operation panel 40 including a button group 41 including various buttons such as a start key, a stop key, and a numeric keypad, and a display unit 42 including a touch panel on the front side. ing. The button group 41 and the display unit 42 allow the operation status to be displayed and the operation input by the user to be performed. The display unit 42 according to the present embodiment is a touch panel having both an input function and a display function, but may be a liquid crystal panel having no input function, for example. The display unit 42 is an example of a display unit.

  Next, an electrical configuration of the MFP 100 according to the present embodiment will be described. As shown in FIG. 2, the MFP 100 of this embodiment includes a controller 30 having a CPU 31, a ROM 32, a RAM 33, and an NVRAM (Non Volatile RAM) 34. The MFP 100 includes an image forming unit 1, an image reading unit 2, an operation panel 40, size sensors 61 and 62, tray sensors 71 and 72, and a communication interface 37, which are controlled by the CPU 31. . The controller 30 in FIG. 2 is a collective term for hardware used for controlling the MFP 100 such as the CPU 31, and does not necessarily represent a single piece of hardware that actually exists in the MFP 100.

  The ROM 32 stores firmware, which is a control program for controlling the MFP 100, various settings, initial values, and the like. The RAM 33 is used as a work area from which various control programs are read or as a storage area for temporarily storing image data. The NVRAM 34 is also used as a storage area for storing various information used in the MFP 100. The RAM 33 or NVRAM 34 is an example of a storage unit.

  The CPU 31 controls each component of the MFP 100 while storing the processing result in the RAM 33 or the NVRAM 34 according to a control program read from the ROM 32 and signals sent from various sensors. The CPU 31 is an example of a control unit. The controller 30 may be a control unit.

  The size sensor 61 is a sensor that outputs different signals depending on the size of the sheets stored in the paper feed tray 91. The MFP 100 uses the output signal of the size sensor 61 to specify the size of the sheets stored in the paper feed tray 91. The size sensor 61 may be, for example, a sensor that outputs a signal that varies depending on the position of a guide disposed in the sheet feed tray 91, or a sheet sensor that outputs a signal that varies depending on the presence or absence of a sheet. A sensor that outputs a different signal depending on the combination of the presence or absence of a sheet obtained from the output signal of each sheet sensor may be provided. The size sensor 62 is a sensor that outputs a different signal depending on the size of the sheets stored in the paper feed tray 92, and may have the same configuration as the size sensor 61.

  The tray sensor 71 is a sensor that outputs different signals depending on whether or not the paper feed tray 91 is set in the MFP 100. The MFP 100 uses the output signal of the tray sensor 71 to determine whether or not the paper feed tray 91 is set in the MFP 100 by the CPU 31. The tray sensor 72 is a sensor that outputs a different signal depending on whether or not the paper feed tray 92 is set in the MFP 100, and may have the same configuration as the tray sensor 71.

  The communication interface 37 is hardware that enables communication with an external device. Specific examples of the communication interface 37 include a wired LAN interface, a wireless LAN interface, and a serial communication interface. Further, it may be a telephone line interface for enabling facsimile communication. The MFP 100 can transmit image data of a document read by the image reading unit 2 to an external device via the communication interface 37. Further, the MFP 100 receives a print job that causes the image forming unit 1 to form an image, a reading job that causes the image reading unit 2 to read an image, or a copy job that performs both from the external device via the communication interface 37. it can.

[Control MFP]
Next, control of MFP 100 will be described. The MFP 100 has a printing function, a reading function, and a facsimile transmission / reception function, and accepts execution instructions for various processes of facsimile transmission, copying, and scanning via the operation panel 40.

  FIG. 3 shows the transition of the screen displayed on the display unit 42 of the operation panel 40. An initial screen 81 shown in FIG. 3A is a screen for receiving selection of a process to be executed. Specifically, on the initial screen 81 of this embodiment, a button 811 corresponding to facsimile transmission, a button 812 corresponding to copying, and a button 813 corresponding to scanning are displayed. The MFP 100 displays an initial screen 81 on the display unit 42 after the power is turned on.

[Copy setting process]
A copy setting process for setting a copy and instructing execution will be described below with reference to the flowchart of FIG. The copy setting process is executed by the CPU 31 when a copy is selected on the initial screen 81 shown in FIG. The selection of the copy can be determined by touching the button 812, for example.

  In the copy setting process, the MFP 100 first displays the copy screen 82 shown in FIG. 3B on the display unit 42 (S101). On the copy screen 82, a button 821 corresponding to the change of the copy setting, a button 822 corresponding to the start of copying, and a box 823 for setting the number of copies are displayed. In the copy screen 82, the setting contents of each item of the copy setting are displayed in the item display area 824. MFP 100 accepts an input from the user.

  After receiving the input from the user, the MFP 100 determines whether or not copy setting has been selected (S111). The selection of the copy setting can be determined, for example, by touching the button 821.

  When the copy setting is selected (S111: YES), the MFP 100 displays the copy setting screen 83 shown in FIG. 3C on the display unit 42 (S112). The copy setting screen 83 displays a button 831 corresponding to the quality setting, a button 832 corresponding to the sheet type, a button 833 corresponding to the magnification setting, and a button 834 corresponding to the end of the copy setting. The In addition, by scrolling the screen, buttons corresponding to other items of the copy setting are also displayed. MFP 100 accepts an input from the user.

  After receiving the input from the user, the MFP 100 determines whether or not the magnification setting has been selected (S113). The selection of the magnification setting can be determined by touching the button 833, for example.

  When the magnification setting is selected (S113: YES), the MFP 100 executes a magnification setting process for accepting the magnification setting (S114). Here, the magnification setting process of S114 will be described with reference to the flowchart of FIG.

  In the magnification setting process, the MFP 100 first acquires the size of the sheet stored in the paper feed tray 91 and the size of the sheet stored in the paper feed tray 92 (S151). Specifically, in the present embodiment, the sheet size of each of the paper feed trays 91 and 92 is acquired using the output signals of the size sensors 61 and 62. S151 is an example of an acquisition process.

  After S151, the MFP 100 determines whether or not there are sheets in the sheet feeding tray 91 and the sheet feeding tray 92, and excludes the sheet size obtained from the sheet feeding tray having no sheet from the selection targets (S152). . There is a low possibility that a sheet size corresponding to a paper feed tray that does not contain sheets is selected as an option on the size selection screen 84 described later. Therefore, the MFP 100 excludes the sheet size from the options and does not select the sheet size on the size selection screen 84.

  The presence / absence of sheets in the paper feed tray 91 is determined by, for example, arranging at least one sheet sensor in the paper feed tray 91, and the MFP 100 corresponds to the absence of sheets in all the sheet sensors arranged in the paper feed tray 91. If a signal is output, it can be determined that there is no sheet. Further, when acquisition of the sheet size by the size sensor fails, it may be determined that there is no sheet. Further, the MFP 100 stores a flag in the RAM 33 and sets the flag when sheet picking fails. In S152, the MFP 100 determines that there is no sheet when the flag is set. Good. In this case, the MFP 100 may clear the flag when detecting an operation that may replenish the sheet, such as opening the paper feed tray or turning off the power.

  After S152, the MFP 100 displays on the display unit 42 a size selection screen 84 for selecting the sheet size shown in FIG. 3D (S153). For example, on the size selection screen 84 of this embodiment, a button 841 corresponding to the sheet size accommodated in the sheet feed tray 91 and a button 842 corresponding to the sheet size accommodated in the sheet feed tray 92 are displayed. Is done. Then, MFP 100 accepts selection of the sheet size by the user.

  Note that the MFP 100 uses, as options on the size selection screen 84, a sheet size that is not excluded in S152 among the sheet sizes acquired in S151. If there is only one sheet size as an option, the MFP 100 omits S153 and proceeds to S154. If there is no sheet size as an option, the MFP 100 displays a message to supplement the sheet on the display unit 42 and ends the magnification setting process.

  After accepting the selection of the sheet size, the MFP 100 acquires a magnification according to the selected sheet size (S154). As shown in FIG. 6, the MFP 100 stores a database (hereinafter referred to as “magnification DB 321”) that stores the size of the standard size and the magnification when enlarging or reducing the standard size to the standard size. I remember it. In step S154, the MFP 100 refers to the magnification DB 321 and reads a list of magnifications corresponding to the selected sheet size. For example, when A3 is selected as the sheet size, a list of magnifications corresponding to A3 corresponding to the sheet size surrounded by the dotted frame X in FIG. 6 is read. That is, in S154, a magnification is obtained with the size after enlargement or reduction as the selected sheet size. Then, the MFP 100 uses the acquired plurality of magnifications as magnification options.

  After S154, the MFP 100 determines whether the number of magnification options is greater than a predetermined value (S155). The predetermined value is a value determined based on the size of characters displayed on the display unit 42 and the size of the display area of the display unit 42, and is stored in the ROM 32 in advance.

  If there are too many options, it is difficult for the user to find the target magnification. Therefore, when the number of magnification options is greater than the predetermined value (S155: YES), the MFP 100 limits the options to the reduction magnification or the enlargement magnification, and thus the acquired magnification is a mixture of reduction and enlargement. Whether or not (S156).

  If the acquired magnification is not a mixture of reduction and enlargement (S156: YES), the number of options does not change even if the reduction magnification or the enlargement magnification is limited. If the number of magnification options is not greater than the predetermined value (S155: NO), it is easy to find the target magnification even if all the options can be selected. Therefore, the MFP 100 causes the display unit 42 to display the magnification selection screen 85 shown in FIG. 3E, which displays all the options acquired in S154 (S161). On the magnification selection screen 85, each option, that is, a button 851 corresponding to each magnification is displayed. In the magnification selection screen 85, the number of buttons 851 that can be displayed is displayed on the display unit 42 in accordance with the display size among the magnifications to be displayed, and the screen can be scrolled to cope with other magnifications that cannot be displayed. A button 851 to be displayed is also displayed. Also, by rearranging the display of each magnification in descending or ascending order, the target magnification can be easily found. S161 is an example of display processing.

  On the other hand, when the acquired magnification is a mixture of reduction and enlargement (S156: NO), the MFP 100 displays the classification selection screen 86 shown in FIG. 3F on the display unit 42 (S171). In the classification selection screen 86, a button 861 corresponding to reduction, a button 862 corresponding to equal magnification, and a button 863 corresponding to enlargement are displayed. Then, MFP 100 accepts selection of classification by the user.

  After accepting the selection of the classification, the MFP 100 determines whether or not the same size is selected (S172). Furthermore, if the same magnification is not selected (S172: NO), it is determined whether enlargement is selected (S173).

  When enlargement is selected (S173: YES), the MFP 100 causes the display unit 42 to display a magnification selection screen 85 in which only magnifications corresponding to enlargement among the magnifications acquired in S154 are selected (S174). On the other hand, if enlargement is not selected (S173: NO), reduction is selected. Therefore, the MFP 100 selects a magnification selection screen 85 using only the magnification corresponding to reduction among the magnifications acquired in S154 as an option. Is displayed on the display unit 42 (S175). S174 and S175 are an example of display processing.

  After displaying the magnification selection screen 85 in S161, S174, or S175, the MFP 100 accepts selection of the magnification by the user. After accepting the selection of the magnification, the MFP 100 sets the selected magnification (S162). If the same size is selected on the classification selection screen 86 (S172: YES), the MFP 100 sets 100% as the magnification.

  After S162, the MFP 100 stores document information, which is information related to the size of the document based on the magnification set in S162, in the RAM 33 (S163). The manuscript information may be information that can acquire the size of the manuscript. For example, the manuscript size may be the manuscript size itself, the standard size name of the manuscript, or a combination of the magnification and the sheet size. There may be. The use of document information will be described later. S163 is an example of a storage process. After S163, the magnification setting process ends.

  Returning to the explanation of FIG. 4, after the magnification setting process in S114 is completed, the process returns to S112. If the magnification setting has not been selected (S113: NO), the MFP 100 determines whether another item of the copy setting has been selected (S121). When another item is selected (S121: YES), the MFP 100 displays a screen for setting the selected item on the display unit 42, and accepts the setting of the selected item (S122). Details of the setting of other items are omitted. After the setting in S122 is completed, the process returns to S112.

  If no other item is selected (S121: NO), the end of the setting change is selected. Therefore, returning to S101, the MFP 100 displays a copy screen 82 in which the change is reflected.

  If the copy setting is not selected (S111: NO), the MFP 100 determines whether the start of copying is selected (S131). The selection of the start of copying can be determined by touching the button 822 on the copy screen 82, for example.

  When the start of copying is selected (S131: YES), the MFP 100 starts a copying operation according to the contents of the copy setting (S132). That is, MFP 100 causes image reading unit 2 to start reading a document, and causes image forming unit 1 to start printing the image of the read document. S132 is an example of a variable magnification copy process. After S132, the copy setting process ends.

  If the start of copying is not selected (S131: NO), the number of copies is input on the copy screen 82. Therefore, the MFP 100 sets the number of copies (S141). Thereafter, the process returns to S101 to display the copy screen 82 reflecting the change in the number of copies.

  Note that after the copy is selected, when the cancel button included in the button group 41 of the operation panel 40 is pressed, the MFP 100 returns to the initial screen 81. In this case, the copy setting process is also terminated.

  According to the copy setting process of the present embodiment, when setting the copy magnification, the MFP 100 selects various magnifications suitable for the selected sheet size, that is, the size of the sheet stored in the paper feed tray. To display. Therefore, for example, the number of options can be reduced as compared with the case where the magnifications of all combinations of standard sizes included in the magnification DB 321 are selected. In addition, even if the number of options is reduced, the magnification that the size of the sheet accommodated in the paper feed tray is used as the option, and the user may select the desired magnification. High and convenient to use.

[Sheet change processing]
Next, sheet change processing, which is an operation when the sheet type is changed in a state where copy is selected, will be described with reference to the flowchart of FIG. In the sheet change process, the sheet type is changed in a state in which the copy is selected, that is, after the copy is selected on the initial screen 81 and until the copy start is instructed or canceled on the copy screen 82. This is executed by the CPU 31 when triggered. For example, when the MFP 100 detects that the setting state of the paper feed tray has changed using an output signal from the tray sensor, or receives a change of the paper feed tray to be used, the sheet type is changed. Judge that it has been changed.

  In the sheet change process, the MFP 100 first acquires the sheet size of the changed sheet (S201). The MFP 100 acquires the changed sheet size based on the output signal of the size sensor 61 or 62 as in S151.

  After S201, the MFP 100 determines whether or not the acquired sheet size is the same as the sheet size of the sheet previously fed from the sheet feed tray whose sheet has been changed (S202). S202 is an example of determination processing. If the sheet sizes are the same (S202: NO), it can be determined that the sheet type has not been changed. Therefore, the MFP 100 ends the sheet change process.

  If the sheet sizes are not the same (S202: NO), it is determined whether document information is stored (S203). The document information is information that is overwritten every time the magnification of the copy setting is set, and is stored in the RAM 33 in S163 of FIG. If the document information is not stored (S203: NO), the size of the document cannot be specified. Therefore, the MFP 100 ends the sheet change process.

  If the document information is stored (S203: YES), the MFP 100 displays a message asking whether to set the magnification on the display unit 42 (S204). Thereafter, MFP 100 accepts a selection as to whether to set a magnification. If it is selected not to set the magnification (S204: NO), since the user does not want to change the magnification, the MFP 100 ends the sheet changing process.

  When setting the magnification is selected (S204: YES), the MFP 100 reads the document information from the RAM 33 and specifies the document size (S211). Then, the MFP 100 acquires a magnification according to the specified document size (S212). In S212, the magnification DB 321 is referred to, and a list of magnifications corresponding to the specified document size is read. For example, when the document size is specified as A5, a list of magnifications corresponding to the sheet size surrounded by the dotted frame Y in FIG. 6 corresponding to A5 is read. That is, in S212, a plurality of magnifications are acquired with the size before enlargement or before reduction as the specified document size. Then, the MFP 100 uses the acquired plurality of magnifications as magnification options.

  In addition, the MFP 100 determines, as a default option (default), a magnification that matches the sheet size acquired in S201 among the plurality of acquired magnifications (S213). That is, the user tends to select the magnification assuming the sheet size, and even when the sheet is changed, there is a high possibility that the user desires a magnification that matches the changed sheet. Therefore, since the document size does not change, the magnification obtained from the combination of the document size and the changed sheet size is set as the default option so that the magnification is displayed with priority over the other options. This makes it easier for the user to select a magnification.

  As a method for preferentially displaying the magnification obtained from the combination of the document size and the changed sheet size over other magnifications, for example, a display is displayed on the upper side in the magnification selection screen 85 in addition to the default option. Yes, increase font, change character color.

  After S213, the MFP 100 causes the display unit 42 to display a magnification selection screen 85 that enables selection of all the options acquired in S212 (S214). In S214, the magnification selection screen 85 is displayed in a state where the option determined in S213 is first selected. S214 is an example of a change display process.

  After displaying the magnification selection screen 85 in S <b> 214, the MFP 100 accepts selection of the magnification by the user on the magnification selection screen 85. Then, after the magnification is selected, the MPF 100 sets the selected magnification (S215). Then, the MFP 100 returns the display on the display unit 42 to the state before switching the screen in S214 (S216). After S216, the sheet change process is terminated.

  When the copy magnification is selected, MFP 100 of this embodiment stores document information that is information regarding the size of the document. According to the above-described sheet change processing, the MFP 100 selects various magnifications from the original size obtained from the original information to various standard sizes of the sheet when the sheet size is changed after the original information is stored. Is displayed on the magnification selection screen 85.

  As described above, changing the options after the sheet is changed based on the document size is effective, for example, when the size of the document is unknown or an irregular size and printing is performed on an expensive sheet. In this case, first, trial printing is performed using an inexpensive sheet, a magnification suitable for the inexpensive sheet is selected, and original information at that time is stored in MFP 100. After that, by changing to an expensive sheet, it becomes possible to select a magnification suitable for the document size. By selecting the magnification desired by the user from these, it is possible to copy a document of unknown size or indeterminate size without wasting expensive sheets.

  Note that this embodiment is merely an example, and does not limit the present invention. Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof. For example, the present invention is not limited to the MFP and can be applied to any apparatus having a copy function.

  In the embodiment, the present invention is applied to MFP 100 having a plurality of paper feed trays, but the present invention may be applied to an apparatus having only one paper feed tray. In this case, S153 is not necessary.

  In the embodiment, the magnification DB 321 stores the size of the standard size and the magnification of the combination of the standard sizes, but only one of them may be stored. For example, even if only the standard size is stored, the MFP 100 may calculate the magnification from the standard size.

  In the embodiment, the sheet size is acquired by the size sensor, but the acquisition method is not limited to this. For example, if the user can set the sheet size of the sheet stored in each sheet feed tray and the MFP 100 stores the sheet size of each sheet feed tray input by the user in the NVRAM 34, the set sheet size is set. May be read from the NVRAM 34 and acquired.

  In the embodiment, when the number of magnification options is larger than a predetermined value, the classification of reduction, equal magnification, or enlargement is selected, and the display options are limited. Good. In the embodiment, when a plurality of sheet sizes are acquired, the sheet size is selected and the options to be displayed are limited. That is, since the magnification options are limited to the magnification according to the sheet size in S154, the number of options is small compared to the case where all magnifications are options. Therefore, even if S155 is omitted and the process proceeds to S161 after S154, even if S153 is omitted and the magnification corresponding to each sheet size is acquired in S154, the options are reduced. There is an effect.

  In the embodiment, the sheet size corresponding to the sheet feeding tray is excluded from the selection target when the sheet is not stored in the sheet feeding tray. However, the sheet size may not be excluded. That is, since the sheet may be replenished later, S152 may be omitted.

  The processing disclosed in the embodiments may be executed by a single CPU, a plurality of CPUs, hardware such as an ASIC, or a combination thereof. Further, the processing disclosed in the embodiment can be realized in various modes such as a recording medium or a method recording a program for executing the processing.
