Description

Technical Field

[0001] The present invention relates to a processing system.

Background Art

[0002] Patent Document 1 describes, as an example of a processing system, an image forming apparatus including a stacker on which a medium on which an image is recorded is loaded, a holding unit that holds the medium, and a reading unit that reads the medium. This image forming apparatus determines whether to convey the medium to the holding unit based on the reading result by the reading unit. The image forming apparatus processes the medium by conveying the medium to the holding unit.

[0003] In the image forming apparatus described in Patent Document 1, when a medium is left on the stacker for a certain period of time, the reading unit reads the medium. The image forming apparatus identifies the user from the reading result and notifies the user that the medium is left on the stacker. Even though the image forming apparatus notifies the user that the medium is left on the stacker, when the medium is left on the stacker, the image forming apparatus conveys the medium to the holding unit. Thus, the image forming apparatus processes the medium when it determines, based on the reading result, that the user does not pick up the medium from the stacker.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In a processing system as described in Patent Document 1, the medium is automatically conveyed from the stacker to the holding unit over time. Therefore, there is a risk that the medium will be automatically conveyed from the stacker to the holding unit against the user's intention. Thus, there is room for improvement in the usability of the processing system.

Means for Solving the Problems

[0006] The processing system for solving the above problems includes a stacker on which one or more media on which images are recorded are loaded, a holding unit for holding the media, a processing path extending from the stacker toward the holding unit, a pick roller for conveying the media from the stacker to the processing path, a reading unit for reading the media conveyed through the processing path, and a control unit for storing index data indicating an index as to whether to convey the media to the holding unit. The control unit causes the pick roller to convey the media from the stacker to the processing path by receiving a processing instruction from the user, and determines whether to convey the media to the holding unit based on the reading data obtained by the reading unit reading the media and the index data.

Embodiments for Carrying Out the Invention

[0008] <First Embodiment> A recording device which is a first embodiment of a processing system will be described with reference to the drawings. The recording device is, for example, an inkjet printer that records images such as characters and photographs by discharging ink, which is an example of a liquid, onto a medium such as paper or fabric.

[0009] As shown in FIG. 1, the recording device 10 includes a housing 11, a recording unit 12, a discharge path 13, a stacker 14, a transport unit 15, a processing path 16, a holding unit 17, a reading unit 18, and a control unit 19.

[0010] The housing 11 houses various components included in the recording device 10. In the first embodiment, the housing 11 has an opening surface 21. At the opening surface 21, an end of the discharge path 13 and an end of the processing path 16 are open.

[0011] The recording unit 12 is configured to record on the medium 99. In the first embodiment, the recording unit 12 is a head. The recording unit 12 has one or more nozzles 22. The recording unit 12 records an image on the medium 99 by discharging a liquid from the nozzles 22 onto the medium 99. The recording unit 12 records an image on the medium 99 based on, for example, image data transmitted from a user. In the first embodiment, the recording unit 12 is housed in the housing 11. The recording unit 12 is not limited to recording by discharging a liquid onto the medium 99, and may record, for example, by fixing powder onto the medium 99. That is, the recording device 10 may be a laser printer.

[0012] The discharge path 13 is a path through which the medium 99 recorded by the recording unit 12 is discharged. The discharge path 13 extends within the housing 11. The discharge path 13 extends from the recording unit 12 toward the stacker 14. In the first embodiment, the end of the discharge path 13 opens to the opening surface 21. The medium 99 recorded by the recording unit 12 is discharged to the stacker 14 by being conveyed through the discharge path 13. The medium 99 discharged from the discharge path 13 falls toward the stacker 14.

[0013] The stacker 14 is located at a position to receive the medium 99 discharged from the discharge path 13. In the first embodiment, the stacker 14 is adjacent to the opening surface 21. The stacker 14 extends from the opening surface 21. The stacker 14 is located below the end of the discharge path 13. Therefore, the stacker 14 receives the medium 99 that falls from the end of the discharge path 13. As a result, one or more media 99 on which images are recorded are stacked on the stacker 14.

[0014] In the first embodiment, the stacker 14 is inclined such that its tip is located above its base end. The base end of the stacker 14 is the end adjacent to the opening surface 21. The medium 99 discharged onto the stacker 14 slides on the stacker 14 such that its end abuts against the opening surface 21. As a result, a plurality of media 99 are stacked on the stacker 14 with their ends aligned.

[0015] The conveyance unit 15 is configured to convey the medium 99. The conveyance unit 15 includes, for example, rollers, belts, etc. The conveyance unit 15 conveys the medium 99 along, for example, the discharge path 13 and the processing path 16. In the first embodiment, the conveyance unit 15 includes the pick-up roller 23. In addition to the pick-up roller 23, the conveyance unit 15 includes a plurality of rollers arranged along the discharge path 13 and the processing path 16, but only the pick-up roller 23 is shown in FIG. 1.

[0016] The pick roller 23 contacts the medium 99 loaded on the stacker 14. By rotating, the pick roller 23 conveys the medium 99 from the stacker 14 to the processing path 16. In the first embodiment, the pick roller 23 contacts the medium 99 loaded on the stacker 14 from above. When a plurality of media 99 are loaded on the stacker 14, the pick roller 23 contacts the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14. Therefore, the pick roller 23 conveys the media 99 to the processing path 16 in order from the uppermost medium 99 among the plurality of media 99.

[0017] In the first embodiment, the conveying unit 15 includes an arm 24 that supports the pick roller 23. The arm 24 rotatably supports the pick roller 23. The arm 24 has a shaft 25. The arm 24 is attached to the housing 11 via the shaft 25.

[0018] The arm 24 is configured to rotate about the shaft 25. Therefore, the arm 24 rotates with respect to the housing 11. When the arm 24 rotates, the pick roller 23 moves with respect to the housing 11. As a result, the pick roller 23 is displaced between a position where it contacts the medium 99 loaded on the stacker 14 and a position where it does not contact the medium 99.

[0019] The pick roller 23 is normally located at a position where it does not contact the medium 99. The pick roller 23 is located at a position where it contacts the medium 99 when conveying the medium 99 from the stacker 14 to the processing path 16.

[0020] In FIG. 1, the pick roller 23 shown by the solid line is located at a position where it does not contact the medium 99. In this case, the pick roller 23 is housed in the housing 11. Therefore, when the pick roller 23 is located at a position where it does not contact the medium 99, the medium 99 falling from the discharge path 13 is not prevented from being loaded on the stacker 14.

[0021] In FIG. 1, the pick roller 23 indicated by the two-dot chain line is located at a position in contact with the medium 99. In this case, the pick roller 23 protrudes from the housing 11. Specifically, the pick roller 23 protrudes from the opening surface 21.

[0022] The processing path 16 is a path extending from the stacker 14 toward the holding unit 17. The processing path 16 extends within the housing 11. The medium 99 is conveyed from the stacker 14 to the holding unit 17 by being conveyed along the processing path 16. In the first embodiment, the starting end of the processing path 16 opens to the opening surface 21. The starting end of the processing path 16 is located below the ending end of the discharge path 13 on the opening surface 21.

[0023] The holding unit 17 is configured to hold the medium 99. Specifically, the holding unit 17 holds the medium 99 on which an image is recorded. The holding unit 17 is, for example, a cassette, a tray, a box, etc. that holds the medium 99. The holding unit 17 may be configured to crush the medium 99. That is, the holding unit 17 may be a shredder. In this case, the holding unit 17 holds the crushed medium 99. The recording apparatus 10 processes the medium 99 by conveying the medium 99 from the stacker 14 to the holding unit 17. The recording apparatus 10 conveys the medium 99 to the holding unit 17, for example, to protect the confidential information recorded on the medium 99.

[0024] The reading unit 18 is configured to read the medium 99 conveyed along the processing path 16. Therefore, the reading unit 18 is located along the processing path 16. In the first embodiment, the recording apparatus 10 includes two reading units 18. The two reading units 18 are located so as to sandwich the processing path 16. That is, the processing path 16 extends between the two reading units 18.

[0025] The two reading units 18 read the front and back surfaces of the medium 99 respectively. That is, in the first embodiment, the two reading units 18 read both sides of the medium 99. The recording apparatus 10 is not limited to the configuration of reading both sides of the medium 99. For example, it may be configured to read only one side of the medium 99 by one reading unit 18. The reading unit 18 obtains reading data A1 by reading the medium 99. The reading unit 18 transmits the obtained reading data A1 to the control unit 19.

[0026] In the first embodiment, the reading unit 18 includes an image sensor. In the first embodiment, the reading unit 18 is an image scanner that reads the image recorded on the medium 99 in full color. Therefore, the reading data A1 is the scan data of the image recorded on the medium 99.

[0027] The reading unit 18 may be a barcode scanner for reading barcodes. In this case, when the recording unit 12 records an image on the medium 99, it also records a barcode. Further, the reading data A1 is waveform data obtained from the barcode.

[0028] The control unit 19 controls the recording apparatus 10 in an overall manner. The control unit 19 controls, for example, the recording unit 12, the conveyance unit 15, the reading unit 18, etc. The control unit 19 can be configured as a circuit including: α: one or more processors that execute various processes according to a computer program; β: one or more dedicated hardware circuits such as an application-specific integrated circuit that executes at least a part of the various processes; or γ: a combination thereof. The processor includes a CPU and memories such as a RAM and a ROM, and the memories store program codes or instructions configured to cause the CPU to execute processes. The memory, that is, the computer-readable medium, includes any readable medium accessible by a general-purpose or dedicated computer.

[0029] The control unit 19 receives commands from the user through a terminal operated by the user, such as a personal computer, a smartphone, etc. The control unit 19 receives commands from the user, for example, by wired communication or wireless communication.

[0030] The control unit 19 receives a recording command from the user. The recording command is a command to cause the recording device 10 to record. When the control unit 19 receives a recording command from the user, it starts recording to the medium 99. That is, when the control unit 19 receives a recording command, it controls the recording unit 12 to record an image on the medium 99. The recording command includes image data. The control unit 19 causes the recording unit 12 to record an image based on the image data. The medium 99 on which the image is recorded is loaded onto the stacker 14 by being conveyed through the discharge path 13.

[0031] The control unit 19 receives a processing command from the user. The processing command is a command to cause the recording device 10 to process the medium 99. When the control unit 19 receives a processing command from the user, it starts processing the medium 99. That is, when the control unit 19 receives a processing command, it controls the conveyance unit 15, for example, the pick roller 23, to convey the medium 99 from the stacker 14 to the holding unit 17.

[0032] When the user sends an incorrect recording command to the recording device 10, an unnecessary medium 99 for the user is loaded onto the stacker 14. The incorrect recording command is caused by the user's operation error. The incorrect recording command is, for example, a recording command including incorrect image data, a recording command with incorrect settings regarding recording, etc.

[0033] For the user, when an incorrect recording instruction is sent to the recording device 10, it is troublesome to go to the recording device 10 to pick up the unnecessary medium 99. Also, for the user, in addition to picking up the medium 99, it is also troublesome to process the medium 99 separately. However, it is not preferable from the viewpoint of confidentiality protection that the unnecessary medium 99 remains loaded on the stacker 14. In such a case, the user sends a processing instruction to the recording device 10. As a result, since the medium 99 unnecessary for the user is processed, the usability of the recording device 10 is good.

[0034] The recording device 10 may be shared by a plurality of people. Therefore, the medium 99 by the first user and the medium 99 by the second user may be loaded on the stacker 14. In this case, for example, if all the media 99 loaded on the stacker 14 are conveyed to the holding unit 17 by the processing instruction of the first user, it is inconvenient for the second user. Also, even when only the medium 99 by the first user is loaded on the stacker 14, the medium 99 necessary for the first user and the medium 99 unnecessary for the first user may be loaded on the stacker 14. In this case, if all the media 99 loaded on the stacker 14 are conveyed to the holding unit 17 by the processing instruction of the first user, it is inconvenient for the first user. Therefore, the recording device 10 needs to determine the medium 99 to be processed from among the plurality of media 99.

[0035] When processing the medium 99, the control unit 19 determines the medium 99 to be processed from among the plurality of media 99. Specifically, the control unit 19 determines the medium 99 to be processed from among the plurality of media 99 based on the index data A2. The index data A2 is data that serves as an index for determining whether to convey the medium 99 to the holding unit 17, that is, whether to process the medium 99.

[0036] In the first embodiment, the index data A2 is image data transmitted from the user. That is, when the user transmits a processing instruction, similar to the recording instruction, the user transmits the image data to the recording device 10. In the first embodiment, the processing instruction includes the image data. When receiving the processing instruction, the control unit 19 stores the image data included in the processing instruction as the index data A2.

[0037] When receiving the recording instruction, the control unit 19 may store the image data included in the recording instruction. In this case, when the user sends a processing instruction to the control unit 19, the user selects one or more pieces of image data from the image data stored in the control unit 19. The image data selected by the user becomes the index data A2.

[0038] The control unit 19 collates the read data A1 and the index data A2. In the first embodiment, the control unit 19 collates the image of the read data A1 and the image of the index data A2. The control unit 19 calculates the image matching rate for the read data A1 and the index data A2. For example, the control unit 19 calculates the image matching rate by comparing the read data A1 and the index data A2 pixel by pixel. The control unit 19 may calculate the matching rate of the character string included in the image as the image matching rate.

[0039] The control unit 19 calculates the image matching rate for each medium 99. That is, when the reading unit 18 reads both sides of the medium 99, the control unit collates the read data A1 on the front side with the index data A2, and collates the read data A1 on the back side with the index data A2. In this case, when the read data A1 on the front side and the index data A2 are exactly the same, and the read data A1 on the back side and the index data A2 are exactly the same, the image matching rate becomes 100%. When the reading unit 18 reads only one side of the medium 99, the control unit collates the read data A1 on that side with the index data A2. In this case, when the read data A1 on one side and the index data A2 are exactly the same, the image matching rate becomes 100%.

[0040] When the index data A2 includes a plurality of images, all the images included in the index data A2 are compared with the image of the read data A1. In this case, a plurality of image matching rates are calculated for one medium 99. The control unit 19 sets the highest image matching rate among the calculated plurality of image matching rates as the image matching rate for that medium 99. That is, it can be said that the control unit 19 determines whether an image that matches the image of the read data A1 is included in the index data A2.

[0041] The control unit 19 stores a threshold value related to the image matching rate. The control unit 19 compares the calculated image matching rate with the threshold value. When the calculated image matching rate is equal to or higher than the threshold value, the control unit 19 determines that the image of the read data A1 and the image of the index data A2 match. In this case, the control unit 19 determines that the medium 99 is a processing target. When the calculated image matching rate is less than the threshold value, the control unit 19 determines that the image of the read data A1 and the image of the index data A2 do not match. In this case, the control unit 19 determines that the medium 99 is not a processing target.

[0042] The control unit 19 determines whether to convey the medium 99 to the holding unit 17 based on the read data A1 and the index data A2. Specifically, the control unit 19 determines whether to convey the medium 99 to the holding unit 17 based on the image matching rate between the read data A1 and the index data A2. In the first embodiment, the control unit 19 determines whether to convey the medium 99 to the holding unit 17 in units of image data. For example, when the user wants to process a medium 99 recorded with incorrect image data, the user sends a processing instruction including similar image data to the recording device 10.

[0043] The control unit 19 may be configured to allow the user to change the threshold value. In this case, the user changes the threshold value by operating the recording device 10. This improves the usability of the recording device 10. The threshold value may be changed by the user through a personal computer, a smartphone, or the like.

[0044] The index data A2 may be table data in which waveform data and ID data are associated. In this case, the control unit 19 pre - records the index data A2. When receiving a recording command, the control unit 19 associates the user who sent the recording command with the ID data. Specifically, the control unit 19, for example, associates the user data included in the recording command with the ID data. Thereby, the user data and the waveform data are associated. The user data is data indicating the IP address, account, etc. of the terminal. The user data and the waveform data may be associated in advance.

[0045] Based on the waveform data associated with the user data, the control unit 19 records a barcode on the medium 99. Thereby, the medium 99 and the user are linked. That is, the barcode recorded on the medium 99 indicates the user who recorded the image on the medium 99.

[0046] When processing the medium 99, the control unit 19 causes the reading unit 18 to read the barcode recorded on the medium 99. The control unit 19 collates the read data A1 which is waveform data with the index data A2 which is table data. Thereby, the control unit 19 identifies the user data from the medium 99. When the user data obtained from the medium 99 matches the user data included in the processing command, the control unit 19 determines that the medium 99 is the object to be processed. When the user data obtained from the medium 99 does not match the user data included in the processing command, the control unit 19 determines that the medium 99 is not the object to be processed.

[0047] Based on the read data A1 and the index data A2, the control unit 19 determines whether to convey the medium 99 to the holding unit 17. In this case, the control unit 19 determines whether to convey it to the holding unit 17 based on the user data of the read data A1 and the index data A2. That is, in this case, the control unit 19 determines whether to convey the medium 99 to the holding unit 17 in units of user data.

[0048] The control unit 19 may include a first mode and a second mode. That is, the control unit 19 may be able to select the first mode or the second mode. The first mode and the second mode are modes related to the processing of the medium 99. When starting the processing of the medium 99, the control unit 19 operates in the first mode or the second mode. For example, the control unit 19 is selected by the user to be in the first mode or the second mode. For example, the processing instruction may include data specifying the first mode or the second mode. That is, when the user sends a processing instruction to the control unit 19, the user selects whether to process the medium 99 in the first mode or in the second mode.

[0049] In the first mode, the control unit 19 determines whether to read the medium 99 by the reading unit 18 and transport the medium 99 to the holding unit 17. That is, in the first mode, as described above, the control unit 19 determines whether to process the medium 99.

[0050] In the second mode, the control unit 19 transports the medium 99 toward the holding unit 17 without reading the medium 99 by the reading unit 18. That is, in the second mode, the control unit 19 does not determine whether to process the medium 99. Therefore, in the second mode, all of the media 99 loaded in the stacker 14 are transported to the holding unit 17. In short, the second mode is a mode for processing all of the media 99 loaded in the stacker 14. Since the reading unit 18 does not read the medium 99 in the second mode, the medium 99 can be processed in a shorter time than in the first mode.

[0051] In the first embodiment, the recording apparatus 10 includes a branch path 27 and a guide unit 28. The branch path 27 extends inside the housing 11. The branch path 27 is a path that branches from the processing path 16. The branch path 27 extends from a branch point 29 in the processing path 16. The branch point 29 is a position between the reading unit 18 and the holding unit 17 in the processing path 16.

[0052] The branch path 27 extends from the branch point 29 toward the stacker 14. The starting end of the branch path 27 is located at the branch point 29. The ending end of the branch path 27 opens to the opening surface 21. In the first embodiment, the branch path 27 merges with the discharge path 13. Therefore, the ending end of the branch path 27 is also the ending end of the discharge path 13. That is, in the first embodiment, the branch path 27 shares a part of it with the discharge path 13. The branch path 27 may be provided independently of the discharge path 13. The medium 99 is re-loaded onto the stacker 14 by being conveyed through the branch path 27.

[0053] The branch path 27 extends so as to invert the posture of the conveyed medium 99 upside down. Therefore, when the medium 99 is conveyed from the processing path 16 to the branch path 27, the posture of the medium 99 is inverted upside down. As a result, in the first embodiment, the medium 99 is re-loaded onto the stacker 14 in a posture that is inverted upside down from when it was loaded on the stacker 14. For example, the medium 99 that was loaded on the stacker 14 with the recording surface facing upward is re-loaded onto the stacker 14 with the recording surface facing downward by being conveyed through the branch path 27. Also, a plurality of media 99 are re-loaded onto the stacker 14 in a loading order different from when they were loaded on the stacker 14 by being conveyed through the branch path 27. Specifically, the loading order of the media 99 is inverted upside down. This is because the pick roller 23 conveys from the medium 99 located at the uppermost position in the stacker 14 to the processing path 16.

[0054] The guide part 28 is located at the position where the processing path 16 and the branch path 27 branch, that is, at the branch point 29. That is, the guide part 28 is located at the branch point 29. The guide part 28 guides the medium 99 conveyed through the processing path 16 to the holding part 17 or the branch path 27. That is, the guide part 28 guides the medium 99 conveyed through the processing path 16 to the holding part 17 or guides it to the stacker 14.

[0055] The guide part 28 is, for example, a flap. The guide part 28 is controlled by the control unit 19. The guide part 28 is configured to be displaced, for example, between the position indicated by the solid line and the position indicated by the two-dot chain line in FIG. 1. The guide part 28 indicated by the solid line closes the branch path 27. In this case, the guide part 28 guides the medium 99 to the holding part 17. The guide part 28 indicated by the two-dot chain line closes the processing path 16. In this case, the guide part 28 guides the medium 99 to the branch path 27. That is, the guide part 28 guides the medium 99 to the stacker 14.

[0056] In the first embodiment, the recording apparatus 10 includes a detection sensor 31. The detection sensor 31 is a sensor that detects the medium 99 loaded on the stacker 14. The detection sensor 31 may be, for example, an optical sensor or an ultrasonic sensor. The detection sensor 31 transmits the detection result to the control unit 19. Based on the detection result of the detection sensor 31, the control unit 19 can determine whether there is a medium 99 on the stacker 14.

[0057] In the first embodiment, the recording apparatus 10 includes a moving mechanism 32. The moving mechanism 32 is a mechanism that moves the stacker 14 up and down. In the first embodiment, the moving mechanism 32 includes a hopper 33. The hopper 33 is located below the stacker 14. The hopper 33 is attached to the stacker 14. When the hopper 33 expands and contracts, the stacker 14 moves up and down.

[0058] The moving mechanism 32 includes a rack 34 and a pinion 35. The rack 34 is connected to the hopper 33 so as to be interlocked with the hopper 33. The pinion 35 meshes with the rack 34. The pinion 35 is controlled by the control unit 19. When the pinion 35 rotates, the rack 34 moves. When the rack 34 moves, the hopper 33 expands and contracts. In this way, by the control unit 19 controlling the pinion 35, the position of the stacker 14 is changed up and down.

[0059] The moving mechanism 32 moves the stacker 14 up and down according to the amount of the medium 99 loaded on the stacker 14. Depending on the amount of the medium 99 loaded on the stacker 14, the position of the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14 may deviate from the start position of the processing path 16. In this case, it becomes difficult to convey the medium 99 loaded on the stacker 14 to the processing path 16. In this regard, by moving the stacker 14 up and down by the moving mechanism 32, the position of the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14 can be aligned with the start position of the processing path 16. As a result, the medium 99 loaded on the stacker 14 can be easily conveyed to the processing path 16.

[0060] Next, a routine executed by the control unit 19 will be described. When receiving a processing instruction from the user, the control unit 19 starts a routine regarding the processing of the medium 99. In the first embodiment, when receiving a processing instruction from the user, the control unit 19 starts the routine shown in FIG. 2.

[0061] As shown in FIG. 2, in step S11, the control unit 19 determines whether there is a medium 99 on the stacker 14. The control unit 19 determines whether there is a medium 99 loaded on the stacker 14 based on the detection result of the detection sensor 31. When the control unit 19 determines that there is a medium 99 on the stacker 14, the process proceeds to step S12. When the control unit 19 determines that there is no medium 99 on the stacker 14, the routine ends.

[0062] In step S12, the control unit 19 conveys the medium 99 to the processing path 16. That is, the control unit 19 conveys the medium 99 from the stacker 14 to the processing path 16 by driving the pick roller 23. At this time, the control unit 19 conveys the media 99 loaded on the stacker 14 to the processing path 16 one by one.

[0063] In step S13, the control unit 19 determines whether the first mode is selected. For example, the control unit 19 determines whether the processing instruction includes data specifying the first mode or data specifying the second mode. The control unit 19 may also determine whether the currently selected mode is the first mode or the second mode. If the first mode is selected, the control unit 19 proceeds to step S14. If the second mode is selected, the control unit 19 proceeds to step S17.

[0064] In step S14, the control unit 19 reads the medium 99 by the reading unit 18. Thereby, the control unit 19 obtains the read data A1 for the medium 99. In step S15, the control unit 19 collates the read data A1 and the index data A2. In the first embodiment, the control unit 19 calculates the image matching rate between the read data A1 and the index data A2. That is, the control unit 19 calculates the image matching rate between the image recorded on the medium 99 and the image of the image data transmitted from the user. In other words, the control unit 19 performs image determination.

[0065] In step S16, the control unit 19 determines whether the medium 99 is a processing target based on the collation result of step S15. In the first embodiment, the control unit 19 determines whether the image matching rate between the read data A1 and the index data A2 is equal to or greater than a threshold value. When the image matching rate is equal to or greater than the threshold value, the control unit 19 determines that the medium 99 is a processing target and proceeds to step S17. When the image matching rate is less than the threshold value, the control unit 19 determines that the medium 99 is not a processing target and proceeds to step S18.

[0066] In step S17, the control unit 19 conveys the medium 99 to the holding unit 17. The control unit 19 guides the medium 99 to the holding unit 17 by controlling the guide unit 28. When the medium 99 is conveyed to the holding unit 17, the medium 99 is processed.

[0067] In step S18, the control unit 19 conveys the medium 99 to the stacker 14. The control unit 19 guides the medium 99 to the branch path 27 by controlling the guide unit 28. As a result, the medium 99 is reloaded onto the stacker 14. Thus, in step S16, the control unit 19 determines whether to convey the medium 99 to the holding unit 17.

[0068] In step S19, the control unit 19 determines whether there is a medium 99 in the stacker 14, similar to step S11. The control unit 19 determines the presence or absence of the medium 99 loaded on the stacker 14 based on the detection result of the detection sensor 31. If the control unit 19 determines that there is a medium 99 in the stacker 14, the process returns to step S12. That is, the control unit 19 repeats the routine shown in FIG. 2 until the medium 99 runs out from the stacker 14. If the control unit 19 determines that there is no medium 99 in the stacker 14, the routine ends.

[0069] In the first embodiment, when the medium 99 is conveyed through the branch path 27, the medium 99 is returned to the stacker 14. Therefore, if the medium 99 returns to the stacker 14 before the routine ends, the detection sensor 31 may detect the medium 99 reloaded onto the stacker 14 again. In this case, there is a possibility that the routine will not end. Therefore, in the first embodiment, it is preferable that the amount of the medium 99 loaded on the stacker 14 is small enough for the routine to end before the medium 99 conveyed to the branch path 27 is reloaded onto the stacker 14.

[0070] Next, the operation and effect of the first embodiment will be described. (1) The control unit 19 causes the pick roller 23 to convey the medium 99 from the stacker 14 to the processing path 16 by receiving a processing command from the user. The control unit 19 determines whether to convey the medium 99 to the holding unit 17 based on the read data A1 and the index data A2.

[0071] According to the above configuration, upon receiving a processing instruction from the user, the control unit 19 determines whether to convey the medium 99 from the stacker 14 to the holding unit 17. Therefore, there is no possibility that the medium 99 is automatically conveyed from the stacker 14 to the holding unit 17 against the intention of the user. Accordingly, the usability of the recording apparatus 10 is improved.

[0072] (2) The control unit 19 determines whether to convey the medium 99 to the holding unit 17 based on the image matching rate between the read data A1 and the index A2 data. According to the above configuration, the control unit 19 can determine whether to convey the medium 99 to the holding unit 17 based on the image matching rate.

[0073] (3) The branch path 27 extends from a position between the reading unit 18 and the holding unit 17 in the processing path 16 toward the stacker 14. According to the above configuration, the medium 99 determined not to be conveyed to the holding unit 17 is returned to the stacker 14 through the branch path 27. Therefore, it is user-friendly.

[0074] (4) In the first mode, the control unit 19 reads the medium 99 by the reading unit 18 and determines whether to convey the medium 99 to the holding unit 17 based on the read data A1 and the index data A2. In the second mode, the control unit 19 conveys the medium 99 toward the holding unit 17 without reading the medium 99 by the reading unit 18. According to the above configuration, since the reading unit 18 does not read the medium 99 in the second mode, the medium 99 is conveyed to the holding unit 17 in a shorter time than in the first mode. Therefore, the processing speed of the processing system is improved.

[0075] (5) The recording apparatus 10, which is a processing system, includes a detection sensor 31 that detects the medium 99 loaded on the stacker 14. According to the above configuration, the control unit 19 can determine the presence or absence of the medium 99 loaded on the stacker 14 by the detection sensor 31.

[0076] (6) The pick roller 23 contacts the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14. According to the above configuration, the pick roller 23 conveys the media 99 to the processing path 16 in order from the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14. Among the plurality of media 99 loaded on the stacker 14, no load of other media 99 is applied to the uppermost medium 99. Therefore, it is easy for the pick roller 23 to convey the media 99 from the stacker 14 to the processing path 16.

[0077] (7) The recording apparatus 10 which is a processing system includes a moving mechanism 32 that moves the stacker 14 up and down. According to the above configuration, the moving mechanism 32 can move the stacker 14 up and down according to the amount of the media 99 loaded on the stacker 14. Therefore, it is easy for the pick roller 23 to convey the media 99 from the stacker 14 to the processing path 16.

[0078] <Second Embodiment> Next, a second embodiment of the processing system will be described. The processing system of the second embodiment is embodied as the recording apparatus 10 as in the first embodiment. In the second embodiment, only some configurations are different from those in the first embodiment. Therefore, in the second embodiment, the configurations different from those in the first embodiment will be mainly described.

[0079] As shown in FIG. 3, in the second embodiment, the conveyance unit 15 includes a pick roller 23, a feed roller 41, a retard roller 42, and a switchback roller 43. In the second embodiment, the pick roller 23 is fixed to the housing 11, unlike in the first embodiment. That is, the pick roller 23 does not move with respect to the housing 11.

[0080] The pick roller 23 is located at a position adjacent to the stacker 14. In the second embodiment, the pick roller 23 contacts the medium 99 loaded on the stacker 14 from below. When a plurality of media 99 are loaded on the stacker 14, the pick roller 23 contacts the lowermost medium 99 among the plurality of media 99 loaded on the stacker 14. Therefore, the pick roller 23 conveys the media 99 to the processing path 16 in order from the lowermost medium 99 among the plurality of media 99.

[0081] In the second embodiment, the pick roller 23 always contacts the medium 99 loaded on the stacker 14. In the second embodiment, different from the first embodiment, the medium 99 can be conveyed from the stacker 14 to the processing path 16 without moving the pick roller 23.

[0082] In the second embodiment, regardless of the amount of the medium 99 loaded on the stacker 14, the positional relationship between the lowermost medium 99 in the stacker 14 and the start position of the processing path 16 does not change. Therefore, that is, in the second embodiment, different from the first embodiment, it is not necessary to move the stacker 14 up and down according to the amount of the medium 99 loaded on the stacker 14. In the second embodiment, the start end of the processing path 16 opens at a position continuous with the stacker 14 on the opening surface 21.

[0083] In the second embodiment, the plurality of media 99 loaded on the stacker 14 are reloaded onto the stacker 14 in the same stacking order as when they were loaded on the stacker 14 by being conveyed through the branch path 27. This is because the pick roller 23 conveys the lowermost medium 99 in the stacker 14 to the processing path 16.

[0084] The feed roller 41 and the retard roller 42 are in contact with the medium 99 conveyed by the pick roller 23. In the second embodiment, the feed roller 41 and the retard roller 42 are located between the pick roller 23 and the processing path 16. The feed roller 41 and the retard roller 42 sandwich the medium 99. The feed roller 41 and the retard roller 42 rotate while sandwiching the medium 99, thereby conveying the medium 99 to the processing path 16.

[0085] The feed roller 41 and the retard roller 42 are configured to separate the medium 99 one by one. For example, the coefficient of friction of the retard roller 42 with respect to the medium 99 is higher than the coefficient of friction of the feed roller 41 with respect to the medium 99. The retard roller 42 rotates passively with respect to the feed roller 41. Thereby, the feed roller 41 and the retard roller 42 separate the medium 99 one by one. The feed roller 41 and the retard roller 42 may be employed in the first embodiment.

[0086] In the second embodiment, the feed roller 41 contacts the medium 99 from above. In the second embodiment, the retard roller 42 contacts the medium 99 from below. Therefore, in the second embodiment, the feed roller 41 and the retard roller 42 are arranged vertically.

[0087] The switchback roller 43 is located along the processing path 16. Specifically, the switchback roller 43 is located between the branch point 29 and the holding portion 17 in the processing path 16. The switchback roller 43 rotates so as to switch back the medium 99. That is, the switchback roller 43 conveys the medium 99 in the direction from the holding portion 17 to the branch point 29 in the processing path 16. The switchback roller 43 conveys the medium 99 to the branch path 27 by switching back the medium 99.

[0088] As described in the first embodiment, when the medium 99 is directly conveyed from the processing path 16 to the branch path 27, the orientation of the medium 99 is inverted vertically. In this regard, in the second embodiment, the medium 99 that has been switched back by the switchback roller 43 is conveyed from the processing path 16 to the branch path 27. As a result, in the second embodiment, unlike the first embodiment, the medium 99 is reloaded onto the stacker 14 in the same orientation as when it was loaded on the stacker 14. That is, in the second embodiment, the medium 99 is reloaded onto the stacker 14 without its orientation being inverted vertically. For example, the medium 99 that was loaded on the stacker 14 with its recording surface facing upward is reloaded onto the stacker 14 with its recording surface facing upward by being conveyed through the branch path 27.

[0089] In the second embodiment, the detection sensor 31 is located below the stacker 14. In the second embodiment, unlike the first embodiment, the detection sensor 31 does not directly detect the medium 99 but indirectly detects the medium 99. The detection sensor 31 may be, for example, an optical non-contact sensor or a contact sensor.

[0090] In the second embodiment, the recording apparatus 10 has a sensor flag 45. One end of the sensor flag 45 is attached to the housing 11. The sensor flag 45 has a shaft 46. The sensor flag 45 is attached to the housing 11 via the shaft 46. The sensor flag 45 is configured to rotate about the shaft 46. The sensor flag 45 is normally housed in the housing 11. Therefore, the sensor flag 45 normally does not prevent the medium 99 falling from the discharge path 13 from being loaded onto the stacker 14. The sensor flag 45 pops out from the opening surface 21 by rotating.

[0091] The sensor flag 45 rotates when the control unit 19 receives a processing command. At this time, the sensor flag 45 rotates only once. The sensor flag 45 rotates so as to approach the stacker 14 from above. That is, in FIG. 3, the sensor flag 45 rotates in the counterclockwise direction.

[0092] As shown in FIG. 4, the sensor flag 45 contacts the medium 99 loaded on the stacker 14 by rotating. Specifically, the sensor flag 45 contacts the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14.

[0093] As shown in FIG. 5, as the amount of the medium 99 loaded on the stacker 14 decreases due to the medium 99 being conveyed to the processing path 16, the sensor flag 45 further rotates. While the sensor flag 45 rotates, the medium 99 returned to the stacker 14 by being conveyed through the branch path 27 is loaded on the sensor flag 45. In this case, the sensor flag 45 is positioned between the medium 99 not being conveyed to the processing path 16 and the medium 99 being conveyed to the processing path 16 in the stacker 14. That is, the sensor flag 45 sorts the medium 99 not being conveyed to the processing path 16 and the medium 99 being conveyed to the processing path 16 on the stacker 14. In this way, the sensor flag 45 sorts the medium 99 for which it has not been determined whether it is a processing target and the medium 99 for which it has been determined whether it is a processing target on the stacker 14.

[0094] As shown in FIG. 6, when all of the media 99 loaded on the stacker 14 are conveyed to the processing path 16, the sensor flag 45 rotates so as to pass through the stacker 14. For example, a slit is formed in the stacker 14 so that the sensor flag 45 can pass through. Thereby, the sensor flag 45 reaches the detection sensor 31. In the second embodiment, the tip of the sensor flag 45 reaches the detection sensor 31. At this time, the detection sensor 31 detects the sensor flag 45.

[0095] When the detection sensor 31 detects the sensor flag 45, the control unit 19 determines that there is no medium 99 on the stacker 14. Specifically, the control unit 19 determines that the medium 99 for which it has not been determined whether it is the processing target is not loaded on the stacker 14. The control unit 19 determines that there is a medium 99 on the stacker 14 until the detection sensor 31 detects the sensor flag 45.

[0096] As shown in FIG. 7, the sensor flag 45 further rotates from the position detected by the detection sensor 31. When the sensor flag 45 rotates, the medium 99 loaded on the sensor flag 45 falls onto the stacker 14. The sensor flag 45 returns to its original position by rotating. When the sensor flag 45 returns to its original position, it stops. The sensor flag 45 rotates again when the control unit 19 receives a processing instruction.

[0097] In the second embodiment, different from the first embodiment, there is no possibility that the medium 99 that has returned to the stacker 14 is conveyed back to the processing path 16 by the sensor flag 45. Therefore, regardless of the amount of the medium 99 loaded on the stacker 14, the control unit 19 can execute the routine regarding the processing of the medium 99. That is, in the second embodiment, the control unit 19 can determine whether the medium 99 is the processing target regardless of the excess of the medium 99 loaded on the stacker 14.

[0098] According to the second embodiment, in addition to the effects (1) to (5) described above, the following effects can be obtained. (8) The switchback roller 43 conveys the medium 99 from the processing path 16 to the branch path 27 by switchbacking the medium 99.

[0099] According to the above configuration, when the medium 99 is conveyed from the processing path 16 to the branch path 27 by a switchback, the medium 99 is re-loaded onto the stacker 14 in the same posture as when it was loaded on the stacker 14. That is, when the medium 99 is loaded on the stacker 14 with the recorded surface facing upward, the medium 99 is conveyed from the processing path 16 to the branch path 27 by a switchback, and the medium 99 is re-loaded onto the stacker 14 with the recorded surface facing upward. In this way, since the posture of the medium 99 returned to the stacker 14 does not change, it is user-friendly.

[0100] (9) The pick roller 23 contacts the lowermost medium 99 among the plurality of media 99 loaded on the stacker 14. According to the above configuration, the pick roller 23 conveys the media 99 to the processing path 16 in order from the lowermost medium 99 among the plurality of media 99 loaded on the stacker 14. Among the plurality of media 99 loaded on the stacker 14, the load of the other media 99 is applied to the lowermost medium 99. As a result, the lowermost medium 99 among the plurality of media 99 loaded on the stacker 14 is pressed against the pick roller 23. Therefore, the pick roller 23 can stably convey the medium 99 from the stacker 14 to the processing path 16.

[0101] <Third Embodiment> Next, a third embodiment of the processing system will be described. The processing system of the third embodiment is embodied as a sorting device. The sorting device may be integrated with, for example, a processing device that performs staple processing and punching processing on the medium 99. In the third embodiment, unlike the first embodiment, it does not have a recording unit 12. In the third embodiment, the medium 99 on which an image has been recorded in advance is loaded on the stacker 14. In the third embodiment, the same reference numerals are given to the configurations common to the first embodiment. In the third embodiment, the points different from the first embodiment will be mainly described.

[0102] As shown in FIG. 8, the sorting device 50 includes a storage unit 51. The storage unit 51 stores the medium 99 conveyed through the branch path 27. The storage unit 51 stores the medium 99 by loading it. In the third embodiment, the branch path 27 extends from the branch point 29 toward the storage unit 51. The storage unit 51 is, for example, a cassette, a tray, a box, etc. for storing the medium 99. In the third embodiment, the storage unit 51 is located above the holding unit 17. The position of the storage unit 51 may be below the holding unit 17 or is not limited.

[0103] In the third embodiment, the pick roller 23 is configured to convey the plurality of media 99 stacked on the stacker 14 in order from the uppermost medium 99, similar to the first embodiment. Therefore, in the third embodiment, similar to the first embodiment, the plurality of media 99 are loaded into the storage unit 51 in a loading order different from when they were stacked on the stacker 14.

[0104] The pick roller 23 may be configured to convey the plurality of media 99 stacked on the stacker 14 in order from the lowermost medium 99, similar to the second embodiment. In this case, similar to the second embodiment, the plurality of media 99 are loaded into the storage unit 51 in the same loading order as when they were stacked on the stacker 14.

[0105] In the third embodiment, the conveying unit 15 does not have the switchback roller 43, similar to the first embodiment. Therefore, in the third embodiment, the medium 99 is directly conveyed from the processing path 16 to the branch path 27. As a result, in the third embodiment, similar to the first embodiment, the medium 99 is re-loaded onto the stacker 14 in a posture that is upside down compared to when it was stacked on the stacker 14.

[0106] The conveying unit 15 may have a switchback roller 43 as in the second embodiment. In this case, the medium 99 is conveyed from the processing path 16 to the branch path 27 by being switchbacked by the switchback roller 43. As a result, the medium 99 is loaded into the storage unit 51 in the same posture as when it was loaded in the stacker 14, similar to the second embodiment.

[0107] In the third embodiment, when the control unit 19 receives a processing instruction, the medium 99 is conveyed from the stacker 14 to the processing path 16. The control unit 19 determines whether to convey the medium 99 to the holding unit 17, that is, whether the medium 99 is a processing target, based on the read data A1 and the index data A2.

[0108] When the medium 99 is a processing target, it is conveyed to the holding unit 17 by being conveyed through the processing path 16. When the medium 99 is not a processing target, it is conveyed to the storage unit 51 by being conveyed through the branch path 27. As a result, the media 99 loaded in the stacker 14 are sorted into the storage unit 51 and the holding unit 17. In this way, according to the sorting device 50, the media 99 unnecessary for the user are removed from the media 99 loaded in the stacker 14.

[0109] In the third embodiment, different from the first and second embodiments, the media 99 that are not processing targets are not returned to the stacker 14 but are conveyed to the storage unit 51. According to the third embodiment, the same effects as those of the first and second embodiments described above can be obtained.

[0110] Each of the above embodiments can be implemented with the following modifications. Each of the above embodiments and the following modification examples can be implemented in combination with each other within a technically non - conflicting range. · The processing system may include a plurality of stackers 14. In this case, the processing path 16 extends from the plurality of stackers 14 toward the holding unit 17.

[0111] ·The control unit 19 may have an automatic mode. The automatic mode is a mode in which the control unit 19 automatically starts the routine shown in FIG. 2 as time passes. The automatic mode is selected by the user. Since the user permits the routine to be automatically started, there is no risk that the medium 99 is automatically conveyed to the holding unit 17 against the user's intention. The automatic mode can coexist with the first mode. In this case, the control unit 19 needs to store in advance the index data A2 used for determination. The control unit 19 determines whether to process the medium 99 by using the index data A2 stored in advance by itself. The automatic mode can coexist with the second mode.

[0112] ·When the image of the read data A1 and the image of the index data A2 match, the control unit 19 may determine that the medium 99 is not a processing target. When the user data of the read data A1 and the user data of the processing instruction match, the control unit 19 may determine that the medium 99 is not a processing target. In this case, when the user wants to leave a specific medium 99 from among a plurality of media 99 stacked on the stacker 14, the user transmits a processing instruction to the processing system. In each of the above embodiments, when the user wants to process a specific medium 99 from among a plurality of media 99 stacked on the stacker 14, the user transmits a processing instruction to the processing system.

[0113] ·When the control unit 19 determines based on the read data A1 and the index data A2 that the medium 99 is not a processing target, the control unit 19 may return the medium 99 from the processing path 16 to the stacker 14 by switching it back.

[0114] The technical idea and its operational effects grasped from the above-described embodiments and modification examples will be described below. (A) The processing system includes a stacker on which one or more media on which images are recorded are loaded, a holding unit that holds the media, a processing path that extends from the stacker toward the holding unit, a pick roller that conveys the media from the stacker to the processing path, a reading unit that reads the media conveyed through the processing path, and a control unit that stores index data indicating an index as to whether to convey the media to the holding unit. The control unit conveys the media from the stacker to the processing path by the pick roller by receiving a processing instruction from a user, and determines whether to convey the media to the holding unit based on the reading data obtained by the reading unit reading the media and the index data.

[0115] According to the above configuration, upon receiving a processing instruction from a user, the control unit determines whether to convey the media from the stacker to the holding unit. Therefore, there is no possibility that the media is automatically conveyed from the stacker to the holding unit contrary to the user's intention. Accordingly, the usability of the processing system is improved.

[0116] (B) In the above processing system, the reading data is scan data of an image recorded on the media, the index data is image data transmitted from a user, and the control unit may determine whether to convey the media to the holding unit based on the image matching rate between the reading data and the index data.

[0117] According to the above configuration, the control unit can determine whether to convey the media to the holding unit based on the image matching rate. (C) The above processing system includes a branch path that branches from the processing path, and the branch path may extend from a position between the reading unit and the holding unit in the processing path toward the stacker.

[0118] According to the above configuration, the media determined not to be conveyed to the holding unit is returned to the stacker through the branch path. Therefore, it is user-friendly. (D) The above processing system includes a switchback roller located between the branch point where the branch path branches in the processing path and the holding unit, and the switchback roller may convey the medium from the processing path to the branch path by switchbacking the medium.

[0119] According to the above configuration, by switchbacking the medium from the processing path to the branch path, the medium is re-loaded onto the stacker in the same posture as when it was loaded on the stacker. That is, when the medium is loaded on the stacker with the recorded surface facing upward, by switchbacking the medium from the processing path to the branch path, the medium is re-loaded onto the stacker with the recorded surface facing upward. Thus, since the posture of the medium returned to the stacker does not change, it is user-friendly.

[0120] (E) In the above processing system, the control unit can select the first mode or the second mode. In the first mode, the reading unit reads the medium, and determines whether to convey the medium to the holding unit based on the read data and the index data. In the second mode, the medium may be conveyed toward the holding unit without the reading unit reading the medium.

[0121] According to the above configuration, in the second mode, since the reading unit does not read the medium, the medium is conveyed to the holding unit in a shorter time compared to the first mode. Therefore, the processing speed of the processing system is improved.

[0122] (F) The above processing system may include a detection sensor that detects the medium loaded on the stacker. According to the above configuration, the control unit can determine the presence or absence of the medium loaded on the stacker by the detection sensor.

[0123] (G) In the above processing system, the pick roller may contact the uppermost medium among the plurality of media loaded on the stacker. According to the above configuration, the pick roller conveys the media to the processing path in order from the media located at the uppermost position among the plurality of media stacked on the stacker. Among the plurality of media stacked on the stacker, no load of other media is applied to the media located at the uppermost position. Therefore, it is easy for the pick roller to convey the media from the stacker to the processing path.

[0124] (H) The above processing system may include a moving mechanism for moving the stacker up and down. According to the above configuration, the moving mechanism can move the stacker up and down according to the amount of media stacked by the stacker. Therefore, it is easy for the pick roller to convey the media from the stacker to the processing path.

[0125] (I) In the above processing system, the pick roller may contact the media located at the lowermost position among the plurality of media stacked on the stacker. According to the above configuration, the pick roller conveys the media to the processing path in order from the media located at the lowermost position among the plurality of media stacked on the stacker.
