The developing device 43 supplies toner to the photosensitive drum 44 and develops the electrostatic latent image formed on the photosensitive drum 44. The transfer device 45 transfers the toner image formed on the photosensitive drum 44 to the sheet S. The fixing device 46 fixes the toner image transferred to the sheet S to the sheet S.

[0017] The transport mechanism 5 sequentially transports multiple sheets S from the paper feed unit 3 to the discharge tray 7 via the image forming unit 4. More specifically, the transport mechanism 5 transports the sheets S from the paper feed unit 3 to one of the discharge trays 7 via the image forming unit 4. The sheets S on which an image has been formed are an example of an "object." In this embodiment, the transport mechanism 5 includes a main body transport mechanism 51.

[0018] The main body conveying mechanism 51 conveys the sheet S from the paper feed unit 3 to the outside of the main body housing 1 via the image forming unit 4. The main body conveying mechanism 51 has a first branching member 511, a plurality of rollers, and a plurality of guide members. The first branching member 511, the plurality of rollers, and the plurality of guide members form a main body conveying path 51L.

[0019] The main body transport path 51L includes a first main body transport path 51a, a second main body transport path 51b, and a third main body transport path 51c. The first main body transport path 51a extends from the paper feed unit 3 to the first branching member 511. The second main body transport path 51b extends from the first branching member 511 to the first discharge outlet 1a. The third main body transport path 51c extends from the first branching member 511 to the second discharge outlet 1b. The first discharge outlet 1a and the second discharge outlet 1b are formed on the side surface of the main body housing 1. In this embodiment, the second discharge outlet 1b is provided above the first discharge outlet 1a.

[0020] The first branching member 511 is rotatable. By rotating, the first branching member 511 switches the destination of the sheet S transported from the first main-body transport path 51a to either the second main-body transport path 51b or the third main-body transport path 51c.

[0021] Sheets S are discharged onto the discharge tray 7. The discharge tray 7 is provided outside the main body housing 1. The discharge tray 7 includes a plurality of main body discharge trays 71. In this embodiment, the plurality of main body discharge trays 71 include a first main body discharge tray 711 and a second main body discharge tray 712. Sheets S discharged from the first discharge outlet 1a are placed onto the first main body discharge tray 711.

In this embodiment, the first main body discharge tray 711 is an inner tray provided in the space within the body. The second main body discharge tray 712 is, for example, a sorting tray.

[0022] The operation unit 8 accepts a keyword. The keyword is an example of "target character information." In detail, the operation unit 8 accepts a plurality of keywords from the user. When the operation unit 8 accepts a plurality of keywords from the user, the operation unit 8 transmits the plurality of keywords to the main body control unit 10.

[0023] Next, an input method for inputting a keyword according to embodiment 1 will be described with reference to Fig. 1 and Fig. 2. Fig. 2 is a diagram showing an example of a keyword input screen G1 according to embodiment 1. As shown in Fig. 2, the keyword input screen G1 is displayed on the touch panel 81 when, for example, a keyword input menu is selected on the system menu screen.

[0024] The operation unit 8 includes a touch panel 81 and a plurality of operation keys 82. The touch panel 81 includes a display and a touch sensor. The display is, for example, a liquid crystal display or an organic electroluminescence display (OLED). The touch sensor is, for example, a resistive touch sensor. The plurality of operation keys 82 includes, for example, a numeric keypad, a start key, and a cancel key. The touch panel 81 displays various screens. The various screens include a keyword input screen G1. The keyword input screen G1 is a screen for accepting a plurality of keywords.

[0025] Specifically, the keyword input screen G1 includes a first keyword input field SB1 and a second keyword input field SB2. The first keyword input field SB1 is a field for inputting a first keyword. The second keyword input field SB2 is a field for inputting a first keyword. For example, the user inputs "aaa" into the first keyword input field SB1 and "bbb" into the second keyword input field SB2. As a result, the first keyword "aaa" and the second keyword "bbb" are stored in the main body storage unit 9.

[0026] Next, functions of the image forming apparatus 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing functions of the main body control unit 10 of the image forming apparatus 100. As shown in Fig. 3, the main body control unit 10 reads out a control program from the main body storage unit 9 and executes it.

[0027] The main storage unit 9 stores various types of data. The main storage unit 9 is configured with a storage device and a semiconductor memory. The storage device is configured with, for example, an HDD (Hard Disk Drive) and / or an SSD (Solid State Drive). The semiconductor memory is configured with, for example, RAM (Random Access Memory) and ROM (Read Only Memory). In this embodiment, the main storage unit 9 stores the first keyword "aaa" and the second keyword "bbb".

[0028] The main body control unit 10 controls the operation of each unit included in the image forming apparatus 100. The main body control unit 10 is configured with a processor such as a CPU (Central Processing Unit). The main body control unit 10 also includes an integrated circuit for image formation processing. The integrated circuit for image formation processing is configured with, for example, an ASIC (Application Specific Integrated Circuit). The main body control unit 10 controls the operation of each unit of the image forming apparatus 100 by executing a control program. Specifically, the main body control unit 10 includes a recognition unit 11 and an acquisition unit 12.

[0029] The recognition unit 11 recognizes character information contained in the images of the multiple documents D for each document D. The recognition unit 11 is, for example, an OCR (Optical Character Reader). Specifically, the recognition unit 11 recognizes character information contained in the images of the documents D based on image data output from the document reading device 2. For example, the recognition unit 11 recognizes character information contained in the image of the first document D based on first image data representing the image of the first document D. Also, the recognition unit 11 recognizes character information contained in the image of the second document D based on second image data representing the image of the second document D.

[0030] The acquisition unit 12 acquires a sheet S on which an image containing a keyword is formed in character information. Specifically, the acquisition unit 12 transports the sheet S on which an image containing a keyword is formed in character information to the discharge tray 7. More specifically, the acquisition unit 12 determines whether the first keyword “aaa” is included in the character information included in the image of the first document D, based on first image data representing the image of the first document D. If the acquisition unit 12 determines that the first keyword “aaa” is included in the character information included in the image of the first document D, the transport mechanism 5 transports the sheet S from the paper feed unit 3 to the first main body discharge tray 711 via the image forming unit 4. On the other hand, if the acquisition unit 12 determines that the first keyword “aaa” is not included in the character information included in the image of the first document D, the transport mechanism 5 does not transport the sheet S. As described above, according to the first embodiment, the user can acquire a sheet S on which the first keyword “aaa” is included in the character information of the document D.

[0031] Furthermore, the acquisition unit 12 determines whether the second keyword "bbb" is included in the character information included in the image of the second original D, based on the second image data representing the image of the second original D. If it is determined that the second keyword "bbb" is included in the character information included in the image of the second original D, the conveyance mechanism 5 conveys the sheet S from the paper feed unit 3 to the second main body discharge tray 712 via the image forming unit 4. On the other hand, if it is determined that the second keyword "bbb" is not included in the character information included in the image of the second original D, the conveyance mechanism 5 does not convey the sheet S. In other words, the conveyance mechanism 5 conveys the sheet S whose character information includes the first keyword "aaa" and the sheet S whose character information includes the second keyword "bbb" to different discharge trays 7. As described above, according to the first embodiment, the user can also acquire the sheet S whose character information includes the second keyword "bbb."

[0032] Next, an acquisition method according to the first embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing the acquisition method according to the first embodiment.

[0033] In step S101, the operation unit 8 accepts a plurality of keywords from the user. Upon accepting the plurality of keywords from the user, the operation unit 8 transmits the plurality of keywords to the main body control unit 10. The process proceeds to step S102.

[0034] In step S102, the document reading device 2 reads the image of the document D and outputs image data representing the image of the document D. The process proceeds to step S103.

[0035] In step S103, the document transport device 30 determines whether or not the document D has been transported. If it is determined that the document transport device 30 has not transported the document D (No in step S103), the process ends.

[0036] On the other hand, if it is determined that the document transport device 30 has transported the document D (Yes in step S103), the process proceeds to step S104.

[0037] In step S104, the obtaining unit 12 determines whether or not a keyword is included in the character information included in the image of the document D, based on the image data representing the image of the document D. If it is determined that a keyword is not included (No in step S104), the processing returns to step S102.

[0038] On the other hand, if it is determined that the keyword is included (Yes in step S104), the process proceeds to step S105.

[0039] In step S105, the image forming unit 4 forms an image on the sheet S fed by the paper feeding unit 3. The process proceeds to step S106.

[0040] In step S106, the conveying mechanism 5 conveys the sheet S to a predetermined main body discharge tray 71. The process returns to step S102.

[0041] In the first embodiment, the configuration in which the number of discharge trays 7 is two has been described, but the number of discharge trays 7 may be three or more.

In the second embodiment, the post-processing transport mechanism 52, together with the main body transport mechanism 51, constitutes the transport mechanism 5. The post-processing discharge tray 72, together with the main body discharge tray 71, constitutes the discharge tray 7.

[0051] The post-processing conveying mechanism 52 includes a plurality of branching members, a plurality of rollers, a plurality of guide members, and an evacuation drum. The plurality of branching members, the plurality of rollers, the plurality of guide members, and the evacuation drum configure a post-processing conveying path 52L.

[0052] The post-processing conveying mechanism 52 conveys the sheet S conveyed into the receiving section 202 to the post-processing discharge tray 72.

[0053] In the second embodiment, the post-processing discharge tray 72 includes a first post-processing discharge tray 721 and a second post-processing discharge tray 722.

[0054] The post-processing control unit 205 controls the operation of each unit of the post-processing device 20. When the post-processing device 20 is attached to the main body housing 1, the post-processing control unit 205 can communicate with the main body control unit 10. In the second embodiment, the post-processing control unit 205 communicates with the main body control unit 10 by, for example, a serial communication method.

[0055] In the second embodiment, the main body control unit 10 acquires device configuration information by communicating with the post-processing control unit 205. The device configuration information indicates the device configuration of the post-processing device 20. The device configuration information is stored in the main body storage unit 9. The device configuration information includes additional tray information indicating the discharge trays 7 (first post-processing discharge tray 721 and second post-processing discharge tray 722) of the post-processing device 20. Upon acquiring the additional tray information, the main body control unit 10 adds the discharge tray 7 indicated by the additional tray information. In the second embodiment, the main body control unit 10 adds the first post-processing discharge tray 721 and the second post-processing discharge tray 722.

[0056] As described above, according to embodiment 2, the user can obtain a sheet S containing the first keyword "aaa" in the character information of the document D, a sheet S containing the second keyword "bbb" in the character information of the document D, a sheet S containing the third keyword "ccc" in the character information of the document D, and a sheet S containing the fourth keyword "ddd" in the character information of the document D.

[0057] [Embodiment 3] An image forming apparatus 100 according to a third embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. 7 is a diagram showing functions of a main body control unit of an image forming apparatus according to a third embodiment of the present invention. FIG. 8 is a flowchart showing an acquisition method according to the third embodiment. In the image forming apparatus 100 according to the first embodiment, the acquisition unit 12 acquires a sheet S on which an image including a keyword in text information is formed, whereas in the image forming apparatus 100 according to the third embodiment, the acquisition unit 12 acquires image data on which an image including a keyword in text information is formed. Below, differences between the third embodiment and the first embodiment will be described, and explanations of parts that overlap with the first embodiment will be omitted.

[0058] As shown in FIG. 7 , the acquisition unit 12 acquires image data on which an image containing a keyword is formed in character information.

[0062] In step S202, the document reading device 2 reads the image of the document D and outputs image data representing the image of the document D. The process proceeds to step S203.

[0063] In step S203, the document transport device 30 determines whether or not the document D has been transported. If it is determined that the document transport device 30 has not transported the document D (No in step S203), the process ends.

[0064] On the other hand, if it is determined that the document transport device 30 has transported the document D (Yes in step S203), the process proceeds to step S204.

[0065] In step S204, the obtaining unit 12 determines whether or not a keyword is included in the character information included in the image of the document D, based on the image data representing the image of the document D. If it is determined that a keyword is not included (No in step S204), the processing returns to step S202.

[0066] On the other hand, if it is determined that the keyword is included (Yes in step S204), the process proceeds to step S205.

[0067] In step S205, the acquisition unit 12 stores image data in which an image containing the keyword in the character information is formed in a predetermined storage area of ​​the main body storage unit 9. The process returns to step S202.
