  Hereinafter, an embodiment of the present invention will be described using the drawings.

  First, the configuration of a system according to the present embodiment will be described.

  FIG. 1 is a block diagram of a system 10 according to the present embodiment.

  As shown in FIG. 1, the system 10 includes an MFP (Multifunction Peripheral) 20 as an image forming apparatus, a computer 30 such as a PC (Personal Computer) for transmitting print data to the MFP 20, and an image based on the print data. And a storage medium 40 such as a Universal Serial Bus (USB) memory storing overlay data for an image to be superimposed on the image.

  The system 10 can be used, for example, when printing documents such as general office documents, contracts, special documents of transaction business, and the like. The user is, for example, a person in charge of the operation of the transaction window, which handles one customer for each customer.

  The MFP 20 and the computer 30 can communicate with each other via a network 11 such as a LAN (Local Area Network) or the Internet. The MFP 20 and the computer 30 may directly communicate with each other in a wired or wireless manner without passing through the network 11.

  The MFP 20 can be connected directly to the storage medium 40 by wire without passing through the network 11. The MFP 20 may be directly connectable to the storage medium 40 wirelessly without passing through the network 11 or may be connectable to the storage medium 40 via the network 11.

  The print data transmitted to the MFP 20 by the computer 30 is generated by, for example, an application of the computer 30 to include text and an image in page units. When printing based on overlay data is performed by MFP 20, the print data transmitted by computer 30 to MFP 20 does not include the form overlay function and the watermark function to avoid overlapping with the overlay based on the overlay data. Is preferred.

  The overlay data stored in storage medium 40 is a file format that does not depend on the resolution of MFP 20, such as PDF (Portable Document Format) format, so that it can be adjusted to the resolution of the image based on the print data. It is good. The overlay data may be data for one page so that it can be combined with an image based on print data in units of one page. Thus, overlay data may be created with a dedicated tool for creating overlay data.

  The overlay data is, for example, form data such as letterhead, watermark, ruled lines, company logo, and the like.

  The system 10 can include many MFPs similar to the MFP 20. Similarly, the system 10 can include a large number of computers similar to the computer 30, and a large number of storage media similar to the storage medium 40, respectively.

  FIG. 2 is a front view of the MFP 20. As shown in FIG. FIG. 3 is a block diagram of the MFP 20. As shown in FIG.

  As shown in FIGS. 2 and 3, the MFP 20 is a display device such as an LCD (Liquid Crystal Display) that displays various information, and an operation unit 21 that is an input device such as a button to which various operations are input. The display unit 22, a scanner 23 as a reading device for reading an image from an original, a printer 24 as a printing device for printing an image on a recording medium such as paper, an external facsimile machine (not shown) and a public telephone line Communicate with external devices directly via fax communication unit 25, which is a fax device that performs fax communication via a communication line, and via network 11 (see FIG. 1), or without passing via network 11, in a wired or wireless manner.

  The printer 24 is a printing unit 24 a that executes printing on the recording medium, and when the recording medium is set, the printing unit 24 a is a supply source of the recording medium to the printing unit 24 a (hereinafter referred to as “medium supply source”). A manual feed tray 24b as a possible priority supply unit, a plurality of supply cassettes 24c as a non-priority supply unit in which a recording medium to be supplied to the printing unit 24a is set but not the manual feed tray 24b, and a printing unit 24a The printing apparatus includes a discharge tray 24d for discharging a recording medium on which printing has been performed, and a manual feed tray sensor 24e as a set detection unit for detecting that the recording medium is set on the manual feed tray 24b.

  The storage unit 27 stores an image forming program 27a. The image forming program 27a may be installed in the MFP 20 at the manufacturing stage of the MFP 20, or may be additionally installed in the MFP 20 from an external storage medium such as an SD card or USB memory, or from the network 11 to the MFP 20. It may be additionally installed.

  The control unit 28 includes, for example, a central processing unit (CPU), a read only memory (ROM) storing a program and various data, and a random access memory (RAM) used as a work area of the CPU. There is. The CPU executes a program stored in the ROM or the storage unit 27.

  The control unit 28 executes the image forming program 27a stored in the storage unit 27 to determine the medium supply source from the manual feed tray 24b and the supply cassette 24c. It functions as an image generation unit 28 b that generates a print image to be printed based on print data, and a setting reception unit 28 c that receives a setting as to whether or not the manual feed tray 24 b is to be the medium supply source.

  Next, the operation of the MFP 20 will be described.

  First, the operation of MFP 20 when the setting as to whether the manual feed tray 24b is to be the supply source is performed preferentially will be described.

  FIG. 4 is a flowchart of the operation of the MFP 20 when the setting as to whether or not the manual feed tray 24b is to be preferentially supplied is executed.

  The control unit 28 executes the operation shown in FIG. 4 when it is instructed via the operation unit 21 to start setting of whether or not the manual feed tray 24b is to be supplied preferentially.

  As shown in FIG. 4, the setting reception means 28c displays the setting screen 50 (see FIG. 5) on the display unit 22 (S101).

  FIG. 5 is a diagram showing an example of the setting screen 50. As shown in FIG.

  The setting screen 50 shown in FIG. 5 includes a radio button 51a for setting that the manual feed tray 24b is not to be the supply source with priority and a radio button for setting that the manual feed tray 24b is the supply source with priority. And 51b. Only one of the radio button 51a and the radio button 51b can be selected.

  The setting screen 50 includes a radio button 52a for setting not to generate a print image based on overlay data, and a radio button 52b for setting to generate a print image based on overlay data. . The radio button 52a and the radio button 52b are grayed out and can not be selected when the radio button 51a is selected, and can be selected only when the radio button 51b is selected. It is possible. Only one of the radio button 52a and the radio button 52b can be selected.

  The setting screen 50 includes an OK button 53 for receiving the setting selected by the radio button 51a, 51b, 52a, 52b, and a cancel button 54 for canceling the reception of the setting.

  As shown in FIG. 4, the setting reception means 28c determines whether the cancel button 54 has been pressed (S102).

  If the setting acceptance means 28c determines in S102 that the cancel button 54 has not been pressed, it determines whether the OK button 53 has been pressed (S103).

  If the setting accepting means 28c determines that the OK button 53 is not pressed in S103, it executes the process of S102.

  When judging that the OK button 53 has been pressed in S103, the setting reception means 28c stores the setting selected by the radio buttons 51a, 51b, 52a, 52b in the storage unit 27 (S104). That is, the setting reception means 28c receives the setting selected by the radio button 51a, 51b, 52a, 52b.

  The setting accepting unit 28c determines in S102 that the cancel button 54 is pressed or executes the processing of S104, and ends the operation illustrated in FIG.

  Next, the operation of MFP 20 when storage medium 40 is connected will be described.

  FIG. 6 is a flowchart of the operation of the MFP 20 when the storage medium 40 is connected.

  When detecting that the storage medium 40 is connected, the control unit 28 executes the operation shown in FIG.

  As shown in FIG. 6, the setting reception means 28c displays the pop-up 60 (see FIG. 7) on the display unit 22 (S131).

  FIG. 7 shows an example of the pop-up 60. As shown in FIG.

  A pop-up 60 shown in FIG. 7 includes a data designation unit 61 for designating overlay data stored as a file in the storage medium 40, and an OK button 62 for receiving overlay data designated by the data designation unit 61. And a cancel button 63 for canceling reception of overlay data.

  As shown in FIG. 6, the setting acceptance unit 28c determines whether the cancel button 63 has been pressed (S132).

  If it is determined in S132 that the cancel button 63 has not been pressed, the setting reception means 28c determines whether the OK button 62 has been pressed (S133).

  When the setting accepting means 28c determines that the OK button 62 is not pressed in S133, it executes the process of S132.

  If it is determined in S133 that the OK button 62 has been pressed, the setting accepting means 28c stores the overlay data designated by the data designation unit 61 from the storage medium 40 in the RAM of the control unit 28 (S134). That is, the setting receiving unit 28 c receives the overlay data specified by the data specifying unit 61.

  The setting accepting means 28c determines in S132 that the cancel button 63 has been pressed or executes the process of S134, and ends the operation shown in FIG.

  The setting acceptance unit 28c does not delete the overlay data stored in the RAM of the control unit 28. That is, the overlay data stored in the RAM of the control unit 28 does not disappear until the power of the MFP 20 is turned off. However, the setting reception means 28c can overwrite the overlay data stored in the RAM of the control unit 28 with new overlay data by executing the process of S134 again.

  Next, the operation of the MFP 20 when print data in the PDL (Page Description Language) format is received will be described.

  8 and 9 are flowcharts of the operation of MFP 20 when print data is received.

  When the control unit 28 receives the print data from the computer 30, the control unit 28 performs the operations shown in FIGS.

  As shown in FIG. 8 and FIG. 9, the image generation means 28b interprets the data of the print data which has not been processed yet from the top according to the PDL according to the command, and prints the image data format for printing such as DisplayList or OrderList. Data, ie, intermediate data for drawing (S161). That is, the image generation unit 28 b interprets the command of the print data stored in the reception buffer and converts it into the drawing intermediate data.

  After the process of S161, the image generation means 28b is a VRAM format data (hereinafter referred to as "VRAM data") in units of drawing objects such as Text, Image, Vector, etc. in the drawing intermediate data generated in S161. It converts into a print image (S162).

  Next, the image generation unit 28b determines whether a page feed process such as a form feed process, a reset, or a control command affecting the page format has occurred (S163).

  If it is determined in S163 that the page feed process has not occurred, the image generation unit 28b executes the process of S161.

  If it is determined in S163 that the page feed process has occurred, the image generation means 28b determines whether or not the setting for using the manual feed tray 24b as the supply source is received preferentially (S164).

  If it is determined in S164 that the setting to use the manual feed tray 24b as the supply source is preferentially received by the image generation unit 28b, it is detected by the manual feed tray sensor 24e that the recording medium is set in the manual feed tray 24b. It is determined whether or not there is (S165).

  If the image generation unit 28b determines that the recording medium is set in the manual feed tray 24b by the manual feed tray sensor 24e in S165, the setting for generating a print image based on the overlay data is received. It is determined whether or not it is (S166).

  If it is determined in S166 that the setting for generating the print image based on the overlay data is received in S166, the image generation unit 28b determines whether the overlay data is stored in the RAM of the control unit 28 (S167).

  If it is determined that the overlay data is stored in the RAM of the control unit 28 in S167, the image generation unit 28b interprets the overlay data stored in the RAM of the control unit 28 from the beginning according to the PDL and draws Converted to intermediate data (S 168).

  Next, the image generation unit 28b converts the drawing intermediate data generated in S168 into VRAM data in drawing object units (S169). That is, the image generation unit 28b generates an image based on the overlay data. Here, the image generation unit 28b generates an image of the size specified in the print data as an image based on the overlay data, regardless of whether the size of the recording medium is specified in the overlay data. In addition, the image generation unit 28b fixes the orientation of the image based on the overlay data in the transport direction of the recording medium, and the print position of the image based on the overlay data is a specific position in the width direction of the manual feed tray 24b (for example, the center Adjust to). When the storage medium is supplied from the manual feed tray 24b, the image generation unit 28b also specifies the print position of the image based on the print data in the same manner as the image based on the overlay data in the width direction of the manual feed tray 24b. Align to the position (eg center).

  After the process of S169, the image generation unit 28b overwrites the VRAM data generated in S169 on the VRAM data of one page generated in S162 immediately before (S170). That is, the image generation unit 28b generates VRAM data, that is, a print image, in which the VRAM data generated in S169 is combined with the VRAM data of one page generated in the immediately preceding S162.

  After the process of S170, the image generation unit 28b determines whether the free space of the RAM of the control unit 28 is equal to or less than a specific capacity (S171).

  If it is determined in S171 that the free space of the RAM of the control unit 28 is not less than the specific capacity, the supply source determining unit 28a determines the manual feed tray 24b as the medium supply source (S172).

  Next, the image generation unit 28b performs printing on the recording medium supplied from the manual feed tray 24b determined in S172, based on the VRAM data of one page generated in the immediately preceding S170. (S173).

  The manual feed tray 24b can supply a recording medium of any size. Therefore, when the printing unit 24a transports the recording medium from the manual feed tray 24b, the MFP 20 performs the transport operation assuming the maximum size of the transportable recording medium, and thus jamming of the recording medium in the transport path, that is, JAM Does not occur. Similarly, when transporting the recording medium from the manual feed tray 24b, the printing unit 24a does not generate an error regarding the size of the recording medium.

  The image generation unit 28b determines in S166 that the setting for generating the print image based on the overlay data is not received or determines in S167 that the overlay data is not stored in the RAM of the control unit 28, the control unit It is determined whether the free space of the RAM 28 is equal to or less than a specific capacity (S174).

  If it is determined in S174 that the free space of the RAM of the control unit 28 is not equal to or less than the specific capacity, the supply source determining unit 28a determines the manual feed tray 24b as the medium supply source (S175).

  Next, the image generation unit 28b performs printing on the recording medium supplied from the manual feed tray 24b determined in S175, based on the VRAM data of one page generated in the immediately preceding S162. (S176).

  The image generation unit 28b determines in S164 that the setting for preferentially using the manual feed tray 24b as the supply source is not received, or the manual feed tray sensor 24e detects that the recording medium is set in the manual feed tray 24b. If it is not determined in S165, it is determined whether the free space of the RAM of the control unit 28 is equal to or less than a specific size (S177).

  If it is determined in S177 that the free space of the RAM of the control unit 28 is not less than the specific capacity, the supply source determining unit 28a determines the medium supply source from the manual feed tray 24b and the supply cassette 24c based on a specific rule. (S178). For example, when the supply source of the recording medium is specifically instructed in the print data, the supply source determination unit 28a may determine the instructed supply source as the medium supply source. Further, when the size of the recording medium is specifically indicated in the print data, the supply source determining unit 28a determines the supply source in which the recording medium of the instructed size is set as the medium supply source. good.

  After the process of S178, the image generation unit 28b performs printing based on the VRAM data of one page generated in the immediately preceding S162 on the recording medium supplied from the medium supply source determined in S178. , And instructs the printing unit 24a (S179).

  If the image generation unit 28b determines in S171, S174 or S177 that the free space of the RAM of the control unit 28 is less than or equal to the specific capacity, an error code indicating that the free capacity of the RAM of the control unit 28 is less than or equal Is displayed on the display unit 22 (S 180).

  FIG. 10 shows an example of the error screen 70. As shown in FIG.

  The error screen 70 shown in FIG. 10 includes text 71 indicating an error code, and a cancel button 72 for ending the display of the error screen 70.

  As shown in FIGS. 8 and 9, after the process of S180, the image generation unit 28b determines whether the cancel button 72 is pressed until it is determined that the cancel button 72 is pressed (S181).

  When the image generation unit 28b determines in S181 that the processing in S173 ends or the cancel button 72 is pressed, the image generation unit 28b determines whether there is a subsequent page (S182).

  If the image generation unit 28b determines in S182 that there is a subsequent page, it executes the process of S161.

  When the image generation unit 28b determines in S182 that there is no subsequent page, the operation illustrated in FIGS. 8 and 9 ends.

  As described above, MFP 20 performs printing based on overlay data by setting the recording medium on manual feed tray 24b (YES in S165) (S173), and the recording medium is not set on manual feed tray 24b. Since the printing not based on the overlay data is executed (S179) according to (NO at S165), the convenience can be improved. That is, a user who desires printing based on overlay data can execute printing based on overlay data simply by setting a recording medium on the manual feed tray 24b and instructing the MFP 20 to print. A user who does not want to print based on overlay data can execute printing based only on print data only by instructing the MFP 20 to print without setting a recording medium in the manual feed tray 24b.

  When the MFP 20 generates a print image based on the overlay data, the MFP 20 generates a print image based on the image generated based on the overlay data in the size specified in the print data (S168 to S170). It is not necessary to prepare a plurality of overlay data according to the size in advance, and printing based on the overlay data can be performed on a recording medium of any size.

  MFP 20 executes printing not based on overlay data even if the recording medium is set to manual feed tray 24b (S179) if the setting not to supply manual feed tray 24b as a priority is given (NO in S164). Can improve convenience.

  Even when the setting that the manual feeding tray 24b is preferentially supplied to the MFP 20 is received (YES in S164), the setting in which the print image is not generated based on the overlay data is received (NO in S166). It is possible to execute printing not based on overlay data (S176), in which the manual feed tray 24b is preferentially supplied as a supply source, so that convenience can be improved.

  If the storage medium 40 has portability such as a USB memory and the MFP 20 can be directly connected to the storage medium 40 by wire or wireless without passing through the network 11, the user desires to use it. Overlay printing can be easily performed by connecting the storage medium 40 to the MFP 20. Therefore, the system 10 is highly convenient when the storage medium 40 has portability and the MFP 20 can be directly connected to the storage medium 40 in a wired or wireless manner without passing through the network 11.

  The MFP 20 stores overlay data from the storage medium 40 in the RAM of the control unit 28 (S134). Therefore, after storing overlay data from the storage medium 40 in the RAM of the control unit 28, the connection with the storage medium 40 is disconnected. Also, overlay printing can be performed. However, MFP 20 may be configured to acquire overlay data from storage medium 40 each time overlay printing is performed. The MFP 20 may store overlay data from the storage medium 40 in the storage unit 27 instead of the RAM of the control unit 28.

  The image forming apparatus of the present invention is an MFP in the present embodiment, but may be an image forming apparatus other than an MFP, such as a printer dedicated machine.
