Description

[Technical Field]

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

[0002] Patent Document 1 describes, as an example of a processing system, an image forming device that includes a stacker on which media with images recorded thereon are loaded, a holding unit that holds the media, and a reading unit that reads the media. Based on the results of reading by the reading unit, the image forming device determines whether or not to transport the media to the holding unit. The image forming device processes the media by transporting the media to the holding unit.

[0003] In the image forming device described in Patent Document 1, when a medium is left in a stacker for a certain period of time, a reading unit reads the medium. The image forming device identifies the user from the reading result and notifies the user that the medium has been left in the stacker. If the medium is still left in the stacker despite the image forming device notifying the user that the medium has been left in the stacker, the image forming device transports the medium to a holding unit. In this way, if the image forming device determines, based on the reading result, that the user will not remove the medium from the stacker, it processes the medium.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-292055 Summary of the Invention [Problem to be solved by the invention]

[0005] In a processing system such as that described in Patent Document 1, media are automatically transported from the stacker to the holding section over time. As a result, there is a risk that media may be automatically transported from the stacker to the holding section against the user's intention. Therefore, there is room for improvement in the usability of the processing system. [Means for solving the problem]

[0006] A processing system that solves the above problem comprises a stacker on which one or more media having images recorded thereon are loaded, a holding unit that holds the media, a processing path extending from the stacker toward the holding unit, a pick roller that transports the media from the stacker to the processing path, a reading unit that reads the media transported along the processing path, and a control unit that stores index data that indicates whether or not to transport the media to the holding unit, and upon receiving a processing command from a user, the control unit causes the pick roller to transport the media from the stacker to the processing path, and determines whether or not to transport the media to the holding unit based on the reading data obtained by the reading unit reading the media and the index data.

DETAILED DESCRIPTION OF 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 ejecting 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 conveying 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 of the recording device 10. In the first embodiment, the housing 11 has an open surface 21. An end of the discharge path 13 and an end of the processing path 16 open into the open surface 21.

[0011] The recording unit 12 is configured to record on a 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 ejecting liquid from the nozzles 22 onto the medium 99. The recording unit 12 records an image on the medium 99, for example, based on image data sent from a user. In the first embodiment, the recording unit 12 is housed in a housing 11. The recording unit 12 is not limited to recording by ejecting liquid onto the medium 99, and may also record by, for example, fixing powder on the medium 99. In other words, the recording device 10 may be a laser printer.

[0012] The discharge path 13 is a path along which the medium 99 recorded by the recording unit 12 is discharged. The discharge path 13 extends inside 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 into the opening surface 21. The medium 99 recorded by the recording unit 12 is transported along the discharge path 13 and discharged to the stacker 14. The medium 99 discharged from the discharge path 13 falls toward the stacker 14.

[0013] The stacker 14 is positioned to receive media 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 positioned below the end of the discharge path 13. Therefore, the stacker 14 receives media 99 that drop from the end of the discharge path 13. As a result, one or more media 99 with images recorded on them are loaded on the stacker 14.

[0014] In the first embodiment, the stacker 14 is inclined so that its leading end is positioned higher than its base end. The base end of the stacker 14 is the end adjacent to the opening surface 21. Media 99 discharged onto the stacker 14 slide on the stacker 14 so that their ends abut against the opening surface 21. As a result, multiple media 99 are stacked on the stacker 14 with their edges aligned.

[0015] The transport unit 15 is configured to transport the medium 99. The transport unit 15 includes, for example, a roller, a belt, etc. The transport unit 15 transports the medium 99, for example, along the discharge path 13 and the processing path 16. In the first embodiment, the transport unit 15 includes a pick roller 23. In addition to the pick roller 23, the transport unit 15 includes multiple rollers arranged along the discharge path 13 and the processing path 16, but only the pick roller 23 is illustrated in FIG. 1.

[0016] The pick roller 23 comes into contact with the media 99 loaded in the stacker 14. The pick roller 23 rotates to transport the media 99 from the stacker 14 to the processing path 16. In the first embodiment, the pick roller 23 comes into contact with the media 99 loaded in the stacker 14 from above. When multiple media 99 are loaded in the stacker 14, the pick roller 23 comes into contact with the uppermost medium 99 among the multiple media 99 loaded in the stacker 14. Therefore, the pick roller 23 transports the multiple media 99 to the processing path 16 in order, starting with the uppermost medium 99 among the multiple media 99.

[0017] In the first embodiment, the conveying section 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 around the shaft 25. Therefore, the arm 24 rotates relative to the housing 11. When the arm 24 rotates, the pick roller 23 moves relative to the housing 11. As a result, the pick roller 23 is displaced between a position where it contacts the media 99 loaded on the stacker 14 and a position where it does not contact the media 99.

[0019] The pick roller 23 is normally positioned so as not to come into contact with the medium 99. The pick roller 23 is positioned so as to come into contact with the medium 99 when the medium 99 is transported from the stacker 14 to the processing path 16.

[0020] 1, pick roller 23, indicated by a solid line, is positioned so as not to come into contact with medium 99. In this case, pick roller 23 is housed in housing 11. Therefore, when pick roller 23 is positioned so as not to come into contact with medium 99, it does not prevent medium 99 falling from discharge path 13 from being stacked on stacker 14.

[0021] 1, pick roller 23, indicated by a two-dot chain line, is positioned to contact medium 99. In this case, pick roller 23 protrudes from housing 11. Specifically, pick roller 23 protrudes from opening surface 21.

[0022] Processing path 16 is a path that extends from stacker 14 toward holding unit 17. Processing path 16 extends inside housing 11. Media 99 are transported along processing path 16 from stacker 14 to holding unit 17. In the first embodiment, the starting end of processing path 16 opens into opening surface 21. The starting end of processing path 16 is located lower than the terminal end of discharge path 13 at opening surface 21.

[0023] The holding unit 17 is configured to hold the medium 99. More specifically, the holding unit 17 holds the medium 99 on which an image is recorded. The holding unit 17 is, for example, a cassette, tray, box, or the like that holds the medium 99. The holding unit 17 may be configured to shred the medium 99. That is, the holding unit 17 may be a shredder. In this case, the holding unit 17 holds the shredded medium 99. The recording device 10 processes the medium 99 by transporting the medium 99 from the stacker 14 to the holding unit 17. The recording device 10 transports the medium 99 to the holding unit 17, for example, to protect confidential information recorded on the medium 99.

[0024] The reading unit 18 is configured to read the medium 99 transported along the processing path 16. Therefore, the reading unit 18 is located along the processing path 16. In the first embodiment, the recording device 10 includes two reading units 18. The two reading units 18 are located on either side of the processing path 16. In other words, the processing path 16 extends between the two reading units 18.

[0025] The two reading units 18 read the front and back sides 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 device 10 is not limited to a configuration that reads both sides of the medium 99, and may be configured, for example, to read only one side of the medium 99 using one reading unit 18. The reading unit 18 obtains read data A1 by reading the medium 99. The reading unit 18 transmits the obtained read 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 an image recorded on the medium 99 in full color. Therefore, the read data A1 is scan data of the image recorded on the medium 99.

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

[0028] The control unit 19 performs overall control of the recording device 10. The control unit 19 controls, for example, the recording unit 12, the transport unit 15, the reading unit 18, etc. The control unit 19 may 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 application-specific integrated circuits, that execute at least some of the various processes; or γ: a combination thereof. The processor includes a CPU and memory, such as RAM and ROM, that stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable medium, includes any readable medium that can be accessed by a general-purpose or dedicated computer.

[0029] The control unit 19 receives commands from a 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 on 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 the image based on the image data. The medium 99 with the image recorded on it is transported along the discharge path 13 and loaded onto the stacker 14.

[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 the processing command from the user, it starts processing the medium 99. That is, when the control unit 19 receives the processing command, it controls the transport unit 15, for example, the pick roller 23, to transport the medium 99 from the stacker 14 to the holding unit 17.

[0032] If a user sends an incorrect recording command to the recording device 10, media 99 that the user does not need will be loaded onto the stacker 14. An incorrect recording command is caused by a user's operational error. Examples of incorrect recording commands include a recording command that includes incorrect image data, a recording command with incorrect recording settings, etc.

[0033] If an incorrect recording command is sent to the recording device 10, it is a hassle for the user to go to the recording device 10 to pick up the unwanted media 99. In addition to picking up the media 99, the user also has to deal with the hassle of separately disposing of the media 99. However, from the perspective of security, it is undesirable to leave the unwanted media 99 stacked in the stacker 14. In such a case, the user sends a processing command to the recording device 10. This allows the unwanted media 99 to be disposed of, making the recording device 10 easy to use.

[0034] The recording device 10 may be shared by multiple people, and therefore, a medium 99 from a first user and a medium 99 from a second user may be stacked on the stacker 14. In this case, for example, if all of the media 99 loaded in the stacker 14 are transported to the holding unit 17 in response to a processing command from the first user, it would be inconvenient for the second user. Also, even if only the media 99 loaded by the first user are loaded in the stacker 14, it is possible that the stacker 14 contains both media 99 that the first user needs and media 99 that the first user does not need. In this case, it would be inconvenient for the first user if all of the media 99 loaded in the stacker 14 were transported to the holding unit 17 in response to a processing command from the first user. For this reason, the recording device 10 needs to determine which of the multiple media 99 are to be processed.

[0035] When processing the medium 99, the control unit 19 determines the medium 99 to be processed from the plurality of media 99. Specifically, the control unit 19 determines the medium 99 to be processed from 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 or not to transport the medium 99 to the holding unit 17, i.e., whether or not to process the medium 99.

[0036] In the first embodiment, the index data A2 is image data sent by the user. That is, the user sends image data to the recording device 10 when sending a processing command, similar to a recording command. In the first embodiment, the processing command includes image data. When the control unit 19 receives the processing command, it stores the image data included in the processing command as index data A2.

[0037] When a recording command is received, the control unit 19 may store the image data included in the recording command. In this case, when the user sends a processing command to the control unit 19, the user selects one or more 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 compares the read data A1 with the index data A2. In the first embodiment, the control unit 19 compares the image of the read data A1 with the image of the index data A2. The control unit 19 calculates an image matching rate between the read data A1 and the index data A2. The control unit 19 calculates the image matching rate by, for example, comparing the read data A1 with the index data A2 pixel by pixel. The control unit 19 may also calculate the matching rate of character strings included in the images as the image matching rate.

[0039] The control unit 19 calculates the image match rate for each medium 99. That is, when the reading unit 18 reads both sides of the medium 99, it compares the read data A1 on the front side with the index data A2, and also compares the read data A1 on the back side with the index data A2. In this case, if the read data A1 on the front side and the index data A2 on the back side perfectly match, the image match rate is 100%. When the reading unit 18 reads only one side of the medium 99, it compares the read data A1 on that side with the index data A2. In this case, if the read data A1 on one side and the index data A2 on the back side perfectly match, the image match rate is 100%.

[0040] If index data A2 contains multiple images, all images contained in index data A2 are compared with the image in read data A1. In this case, multiple image match rates are calculated for one medium 99. The control unit 19 determines the highest image match rate among the multiple calculated image match rates as the image match rate for that medium 99. In other words, the control unit 19 determines whether index data A2 contains an image that matches the image in read data A1.

[0041] The control unit 19 stores a threshold value for the image matching rate. The control unit 19 compares the calculated image matching rate with the threshold value. If the calculated image matching rate is equal to or greater than the threshold value, the control unit 19 determines that the image in the read data A1 and the image in the index data A2 match. In this case, the control unit 19 determines that the medium 99 is to be processed. If the calculated image matching rate is less than the threshold value, the control unit 19 determines that the image in the read data A1 and the image in the index data A2 do not match. In this case, the control unit 19 determines that the medium 99 is not to be processed.

[0042] The control unit 19 determines whether to transport 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 transport the medium 99 to the holding unit 17 based on the image match rate between the read data A1 and the index data A2. In the first embodiment, the control unit 19 determines whether to transport the medium 99 to the holding unit 17 on an image data basis. For example, when a user wants to process a medium 99 recorded with incorrect image data, the user sends a processing command 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 also be changed by the user via a personal computer, smartphone, or the like.

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

[0045] The control unit 19 records a barcode on the medium 99 based on the waveform data associated with the user data. This associates the medium 99 with the user. In other words, 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 compares the read data A1, which is waveform data, with the index data A2, which is table data. In this way, the control unit 19 identifies user data from the medium 99. If 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 to be processed. If 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 to be processed.

[0047] The control unit 19 determines whether or not to transport the medium 99 to the holding unit 17 based on the read data A1 and the index data A2. In this case, the control unit 19 determines whether or not to transport the medium 99 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 or not to transport the medium 99 to the holding unit 17 on a user data basis.

[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 processing of the medium 99. The control unit 19 operates in the first mode or the second mode when starting processing of the medium 99. The control unit 19 is selected in the first mode or the second mode, for example, by a user. For example, a processing command may include data specifying the first mode or the second mode. That is, when sending a processing command to the control unit 19, the user selects whether to process the medium 99 in the first mode or the second mode.

[0049] In the first mode, the control unit 19 reads the medium 99 using the reading unit 18 and determines whether or not to transport the medium 99 to the holding unit 17. That is, in the first mode, as described above, the control unit 19 determines whether or not 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 with the reading unit 18. That is, in the second mode, the control unit 19 does not determine whether or not 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 in which all of the media 99 loaded in the stacker 14 are processed. In the second mode, the reading unit 18 does not read the medium 99, so the media 99 can be processed in a shorter time than in the first mode.

[0051] In the first embodiment, the recording device 10 includes a branch path 27 and a guide unit . Branch path 27 extends within housing 11. Branch path 27 is a path that branches off from processing path 16. Branch path 27 extends from branch point 29 on processing path 16. Branch point 29 is a position on processing path 16 between reading unit 18 and holding unit 17.

[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 terminal 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, and therefore the terminal end of the branch path 27 is also the terminal end of the discharge path 13. That is, in the first embodiment, the branch path 27 shares a portion with the discharge path 13. The branch path 27 may be provided independently of the discharge path 13. The media 99 are reloaded onto the stacker 14 by being transported along the branch path 27.

[0053] The branch path 27 extends so as to invert the orientation of the transported medium 99 upside down. Therefore, when the medium 99 is transported from the processing path 16 to the branch path 27, the orientation of the medium 99 is inverted upside down. As a result, in the first embodiment, the medium 99 is reloaded in the stacker 14 in an orientation that is upside down from when it was loaded in the stacker 14. For example, a medium 99 that was loaded in the stacker 14 with its recorded surface facing upward is reloaded in the stacker 14 with its recorded surface facing downward by being transported along the branch path 27. Furthermore, multiple media 99 are reloaded in the stacker 14 in a different stacking order from when they were loaded in the stacker 14 by being transported along the branch path 27. Specifically, the stacking order of the media 99 is inverted upside down. This is because the pick roller 23 transports the medium 99 located highest in the stacker 14 to the processing path 16.

[0054] Guide unit 28 is located at the position where processing path 16 and branch path 27 branch off, i.e., at branch point 29. That is, guide unit 28 is located at branch point 29. Guide unit 28 guides medium 99 being transported on processing path 16 to holding unit 17 or branch path 27. That is, guide unit 28 guides medium 99 being transported on processing path 16 to holding unit 17 or to stacker 14.

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

[0056] In the first embodiment, the recording device 10 includes a detection sensor 31. The detection sensor 31 is a sensor that detects media 99 loaded in 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 or not media 99 are present in the stacker 14.

[0057] In the first embodiment, the recording apparatus 10 includes a movement mechanism 32. The movement mechanism 32 is a mechanism that moves the stacker 14 up and down. In the first embodiment, the movement mechanism 32 includes a hopper 33. The hopper 33 is located below the stacker 14. The hopper 33 is attached to the stacker 14. The stacker 14 moves up and down as the hopper 33 extends and retracts.

[0058] The movement mechanism 32 includes a rack 34 and a pinion 35. The rack 34 is connected to the hopper 33 so as to move in conjunction 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. As the rack 34 moves, the hopper 33 expands and contracts. In this way, the position of the stacker 14 is changed up and down by the control unit 19 controlling the pinion 35.

[0059] The movement mechanism 32 moves the stacker 14 up and down depending on the amount of media 99 loaded in the stacker 14. Depending on the amount of media 99 loaded in the stacker 14, the position of the uppermost medium 99 among the multiple media 99 loaded in the stacker 14 may be misaligned with the start position of the processing path 16. In this case, it becomes difficult for the media 99 loaded in the stacker 14 to be transported to the processing path 16. In this regard, by moving the stacker 14 up and down using the movement mechanism 32, the position of the uppermost medium 99 among the multiple media 99 loaded in the stacker 14 can be aligned with the start position of the processing path 16. This makes it easier for the media 99 loaded in the stacker 14 to be transported to the processing path 16.

[0060] Next, a description will be given of the routine executed by the control unit 19. When the control unit 19 receives a processing command from the user, it starts a routine related to processing of the medium 99. In the first embodiment, when the control unit 19 receives a processing command from the user, it starts the routine shown in FIG.

[0061] 2, in step S11, the control unit 19 determines whether or not there are media 99 in the stacker 14. The control unit 19 determines whether or not there are media 99 loaded in the stacker 14 based on the detection result of the detection sensor 31. If the control unit 19 determines that there are media 99 in the stacker 14, it proceeds to step S12. If the control unit 19 determines that there are no media 99 in the stacker 14, it ends the routine.

[0062] In step S12, the control unit 19 transports the medium 99 to the processing path 16. That is, the control unit 19 drives the pick roller 23 to transport the medium 99 from the stacker 14 to the processing path 16. At this time, the control unit 19 transports the media 99 stacked in 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 command includes data specifying the first mode or data specifying the second mode. The control unit 19 may 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 using the reading unit 18. As a result, the control unit 19 obtains read data A1 for the medium 99. In step S15, the control unit 19 compares the read data A1 with 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 sent by the user. In other words, the control unit 19 performs image judgment.

[0065] In step S16, the control unit 19 determines whether the medium 99 is a processing target based on the comparison 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. If the image matching rate is equal to or greater than the threshold, the control unit 19 determines that the medium 99 is a processing target and proceeds to step S17. If the image matching rate is less than the threshold, 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 transports the medium 99 to the holding unit 17. The control unit 19 controls the guide unit 28 to guide the medium 99 to the holding unit 17. By transporting the medium 99 to the holding unit 17, the medium 99 is processed.

[0067] In step S18, the control unit 19 transports the medium 99 to the stacker 14. The control unit 19 controls the guide unit 28 to guide the medium 99 to the branch path 27. As a result, the medium 99 is reloaded into the stacker 14. In this way, in step S16, the control unit 19 determines whether or not to transport the medium 99 to the holder 17.

[0068] In step S19, the control unit 19 determines whether or not there are media 99 in the stacker 14, similar to step S11. The control unit 19 determines whether or not there are media 99 loaded in the stacker 14 based on the detection result of the detection sensor 31. If the control unit 19 determines that there are media 99 in the stacker 14, it returns the process to step S12. That is, the control unit 19 repeats the routine shown in FIG. 2 until all the media 99 are removed from the stacker 14. If the control unit 19 determines that there are no media 99 in the stacker 14, it ends the routine.

[0069] In the first embodiment, when the media 99 are transported along the branch path 27, the media 99 are returned to the stacker 14. Therefore, if the media 99 return to the stacker 14 before the routine is completed, the detection sensor 31 may again detect the media 99 that have been reloaded on the stacker 14. In this case, the routine may not be completed. Therefore, in the first embodiment, it is preferable that the amount of media 99 loaded on the stacker 14 is small enough that the routine can be completed before the media 99 transported along the branch path 27 are reloaded on the stacker 14.

[0070] Next, the operation and effects of the first embodiment will be described. (1) Upon receiving a processing command from the user, the control unit 19 causes the pick roller 23 to transport the medium 99 from the stacker 14 to the processing path 16. The control unit 19 determines whether to transport 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 command from the user, the control unit 19 determines whether or not to transport the medium 99 from the stacker 14 to the holding unit 17. Therefore, there is no risk that the medium 99 will be automatically transported from the stacker 14 to the holding unit 17 against the user's intention. This improves the usability of the recording device 10.

[0072] (2) The control unit 19 determines whether or not to convey the medium 99 to the holder 17 based on the image match rate between the read data A1 and the index A2 data. According to the above configuration, the control unit 19 can determine whether or not to transport the medium 99 to the holder 17 based on the image match rate.

[0073] (3) The branch path 27 extends from a position on the processing path 16 between the reading unit 18 and the holding unit 17 toward the stacker 14 . According to the above configuration, media 99 that are determined not to be transported to holding unit 17 are returned to stacker 14 via branch path 27. This provides ease of use for the user.

[0074] (4) In the first mode, the control unit 19 reads the medium 99 using the reading unit 18 and determines whether to transport 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 transports the medium 99 toward the holding unit 17 without reading the medium 99 using the reading unit 18. According to the above configuration, in the second mode, the reading unit 18 does not read the medium 99, so the medium 99 is transported to the holding unit 17 in a shorter time than in the first mode. This improves the processing speed of the processing system.

[0075] (5) The recording device 10, which is a processing system, includes a detection sensor 31 that detects the media 99 loaded on the stacker 14. According to the above configuration, the control unit 19 can determine whether or not there are media 99 stacked on the stacker 14 by the detection sensor 31.

[0076] (6) The pick roller 23 comes into contact with the uppermost medium 99 among the plurality of media 99 stacked on the stacker 14 . According to the above configuration, pick roller 23 transports media 99 from the stacker 14 to processing path 16 in order, starting with the uppermost medium 99. The uppermost medium 99 from the multiple media 99 loaded on stacker 14 is not subjected to the weight of the other media 99. This makes it easier for pick roller 23 to transport media 99 from stacker 14 to 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 in accordance with the amount of media 99 loaded on the stacker 14. This makes it easier for the pick roller 23 to transport 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 a recording device 10, similar to the first embodiment. The second embodiment differs from the first embodiment only in some of its configuration. Therefore, the second embodiment will mainly be described with respect to the configuration that differs from the first embodiment.

[0079] As shown in FIG. 3, in the second embodiment, the conveying section 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 the first embodiment. That is, the pick roller 23 does not move relative to the housing 11.

[0080] The pick roller 23 is located adjacent to the stacker 14. In the second embodiment, the pick roller 23 contacts the media 99 stacked in the stacker 14 from below. When multiple media 99 are stacked in the stacker 14, the pick roller 23 contacts the lowest medium 99 among the multiple media 99 stacked in the stacker 14. Therefore, the pick roller 23 transports the multiple media 99 to the processing path 16 in order, starting with the lowest medium 99 among the multiple media 99.

[0081] In the second embodiment, the pick roller 23 is always in contact with the media 99 loaded in the stacker 14. Unlike the first embodiment, in the second embodiment, the media 99 can be transported from the stacker 14 to the processing path 16 without moving the pick roller 23.

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

[0083] In the second embodiment, the plurality of media 99 loaded in the stacker 14 are transported along the branch path 27 and are reloaded in the stacker 14 in the same stacking order as when they were loaded in the stacker 14. This is because the pick roller 23 transports the media 99 located lowest in the stacker 14 to the processing path 16.

[0084] The feed roller 41 and the retard roller 42 come into contact with the medium 99 being transported by the pick roller 23. In the second embodiment, the feed roller 41 and the retard roller 42 are positioned between the pick roller 23 and the processing path 16. The feed roller 41 and the retard roller 42 sandwich the medium 99 between them. The feed roller 41 and the retard roller 42 rotate with the medium 99 sandwiched between them, thereby transporting the medium 99 to the processing path 16.

[0085] The feed roller 41 and the retard roller 42 are configured to separate the media 99 into individual sheets. For example, the coefficient of friction of the retard roller 42 with respect to the media 99 is higher than the coefficient of friction of the feed roller 41 with respect to the media 99. The retard roller 42 rotates in response to the feed roller 41. As a result, the feed roller 41 and the retard roller 42 separate the media 99 into individual sheets. 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 aligned vertically.

[0087] Switchback roller 43 is located along processing path 16. Specifically, switchback roller 43 is located in processing path 16 between branch point 29 and holding unit 17. Switchback roller 43 rotates to switchback medium 99. That is, switchback rollers 43 transport medium 99 in the direction from holding unit 17 toward branch point 29 on processing path 16. Switchback rollers 43 switchback medium 99, thereby transporting medium 99 to branch path 27.

[0088] As described in the first embodiment, when the medium 99 is transported directly from the processing path 16 to the branch path 27, the orientation of the medium 99 is inverted upside down. In contrast, in the second embodiment, the medium 99 is switched back by the switchback rollers 43 and transported 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 on the stacker 14 in the same orientation as when it was loaded on the stacker 14. That is, in the second embodiment, the orientation of the medium 99 is reloaded on the stacker 14 without being inverted upside down. For example, a medium 99 that was loaded on the stacker 14 with its recording surface facing upward is reloaded on the stacker 14 with its recording surface facing upward by being transported along the branch path 27.

[0089] In the second embodiment, the detection sensor 31 is located below the stacker 14. Unlike the first embodiment, the detection sensor 31 in the second embodiment does not directly detect the media 99, but rather indirectly detects the media 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 device 10 has a sensor flag 45. One end of the sensor flag 45 is attached to the housing 11. The sensor flag 45 has an axis 46. The sensor flag 45 is attached to the housing 11 via the axis 46. The sensor flag 45 is configured to rotate around the axis 46. The sensor flag 45 is normally housed in the housing 11. Therefore, the sensor flag 45 does not normally prevent media 99 dropping from the discharge path 13 from being stacked on the stacker 14. The sensor flag 45 rotates to protrude from the opening surface 21.

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

[0092] 4, the sensor flag 45 rotates to come into contact with the media 99 loaded on the stacker 14. Specifically, the sensor flag 45 comes into contact with the uppermost medium 99 among the plurality of media 99 loaded on the stacker 14.

[0093] As shown in FIG. 5 , the sensor flag 45 continues to rotate as the amount of media 99 loaded on the stacker 14 decreases as media 99 are transported onto the processing path 16. While the sensor flag 45 rotates, media 99 that have been transported along the branch path 27 and returned to the stacker 14 are loaded onto the sensor flag 45. In this case, the sensor flag 45 is positioned in the stacker 14 between the media 99 that have not been transported onto the processing path 16 and the media 99 that have been transported onto the processing path 16. That is, the sensor flag 45 separates the media 99 that have not been transported onto the processing path 16 from the media 99 that have been transported onto the processing path 16 on the stacker 14. In this way, the sensor flag 45 separates the media 99 that have not been determined as to whether they are to be processed from the media 99 that have been determined as to whether they are to be processed on the stacker 14.

[0094] As shown in FIG. 6 , when all of the media 99 stacked in the stacker 14 have been transported to the processing path 16, the sensor flag 45 rotates to pass through the stacker 14. For example, a slit is formed in the stacker 14 to allow the sensor flag 45 to pass through. This allows the sensor flag 45 to reach 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 are no media 99 in the stacker 14. More specifically, the control unit 19 determines that there are no media 99 loaded in the stacker 14 that have not yet been determined as to whether they are to be processed. The control unit 19 continues to determine that there are media 99 in the stacker 14 until the detection sensor 31 detects the sensor flag 45.

[0096] As shown in Figure 7, the sensor flag 45 rotates further from the position where it is detected by the detection sensor 31. As the sensor flag 45 rotates, the media 99 loaded on the sensor flag 45 fall into the stacker 14. The sensor flag 45 returns to its original position by rotating. Once the sensor flag 45 returns to its original position, it stops. When the control unit 19 receives a processing command, the sensor flag 45 rotates again.

[0097] In the second embodiment, unlike the first embodiment, the sensor flag 45 prevents the medium 99 that has returned to the stacker 14 from being transported back to the processing path 16. Therefore, the control unit 19 can execute the routine related to the processing of the medium 99 regardless of the amount of the medium 99 loaded on the stacker 14. In other words, in the second embodiment, the control unit 19 can determine whether or not the medium 99 is to be processed regardless of whether or not there is an excess of the medium 99 loaded on the stacker 14.

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

[0099] According to the above configuration, by transporting the medium 99 from the processing path 16 to the branch path 27 by switchback, the medium 99 is reloaded in the stacker 14 in the same orientation as when it was loaded in the stacker 14. In other words, if the medium 99 was loaded in the stacker 14 with the recorded side facing upward, by transporting the medium 99 from the processing path 16 to the branch path 27 by switchback, the medium 99 is reloaded in the stacker 14 with the recorded side facing upward. In this way, the orientation of the medium 99 returned to the stacker 14 does not change, which is convenient for the user.

[0100] (9) The pick roller 23 comes into contact with the lowest medium 99 among the plurality of media 99 stacked on the stacker 14 . According to the above configuration, the pick roller 23 transports the media 99 stacked on the stacker 14 to the processing path 16 in order, starting with the lowest medium 99. The weight of the other media 99 is applied to the lowest medium 99 among the media 99 stacked on the stacker 14. As a result, the lowest medium 99 among the media 99 stacked on the stacker 14 is pressed against the pick roller 23. Therefore, the pick roller 23 can stably transport the media 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 a processing device that staples and punches media 99, for example. Unlike the first embodiment, the third embodiment does not have a recording unit 12. In the third embodiment, media 99 with pre-recorded images are loaded onto a stacker 14. In the third embodiment, components common to the first embodiment are denoted by the same reference numerals. In the third embodiment, differences 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 media 99 transported along the branch path 27. The storage unit 51 stores the media 99 by stacking them. 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, tray, box, or the like that stores the media 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, and is not limited thereto.

[0103] In the third embodiment, similar to the first embodiment, the pick roller 23 is configured to transport the media 99 stacked in the stacker 14 in order, starting with the uppermost medium 99. Therefore, in the third embodiment, similar to the first embodiment, the media 99 are stacked in the storage unit 51 in a different stacking order than when they were stacked in the stacker 14.

[0104] As in the second embodiment, pick roller 23 may be configured to transport media 99 stacked in stacker 14 in order, starting with the lowest medium 99. In this case, as in the second embodiment, multiple media 99 are stacked in storage unit 51 in the same stacking order as when they were stacked in stacker 14.

[0105] In the third embodiment, the transport unit 15 does not have the switchback rollers 43, as in the first embodiment. Therefore, in the third embodiment, the medium 99 is transported directly from the processing path 16 to the branch path 27. As a result, in the third embodiment, as in the first embodiment, the medium 99 is reloaded onto the stacker 14 in a position that is upside down from when it was loaded onto the stacker 14.

[0106] As in the second embodiment, the conveying section 15 may have switchback rollers 43. In this case, the medium 99 is switched back by the switchback rollers 43 and conveyed from the processing path 16 to the branch path 27. As a result, as in the second embodiment, the medium 99 is stacked in the storage section 51 in the same orientation as when it was stacked in the stacker 14.

[0107] In the third embodiment, when the control unit 19 receives a processing command, the medium 99 is transported from the stacker 14 to the processing path 16. Based on the read data A1 and the index data A2, the control unit 19 determines whether or not to transport the medium 99 to the holding unit 17, i.e., whether or not the medium 99 is to be processed.

[0108] If the media 99 are to be processed, they are transported to the holding section 17 by being conveyed along the processing path 16. If the media 99 are not to be processed, they are transported to the storage section 51 by being conveyed along the branch path 27. As a result, the media 99 loaded in the stacker 14 are sorted into the storage section 51 and the holding section 17. In this way, the sorting device 50 removes media 99 that are not needed by the user from the media 99 loaded in the stacker 14.

[0109] In the third embodiment, unlike the first and second embodiments, media 99 that are not to be processed are not returned to the stacker 14, but are transported to the storage section 51. According to the third embodiment, the same effects as those of the first and second embodiments described above can be obtained.

[0110] The above-described embodiments can be modified as follows: The above-described embodiments and the following modifications can be combined with each other within the scope of technical compatibility. The processing system may include multiple stackers 14. In this case, the processing path 16 extends from the multiple stackers 14 toward the holder 17.

[0111] The control unit 19 may have an automatic mode. In the automatic mode, the control unit 19 automatically starts the routine shown in FIG. 2 over time. The automatic mode is selected by the user. Because the user allows the routine to be started automatically, there is no risk of the medium 99 being automatically transported 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 pre-store the index data A2 used for the determination. The control unit 19 uses the index data A2 that it has pre-stored to determine whether or not to process the medium 99. The automatic mode can coexist with the second mode.

[0112] The control unit 19 may determine that the medium 99 is not to be processed if the image in the read data A1 matches the image in the index data A2. The control unit 19 may determine that the medium 99 is not to be processed if the user data in the read data A1 matches the user data in the processing command. In this case, when a user wants to keep a specific medium 99 from the multiple media 99 loaded on the stacker 14, the user sends a processing command to the processing system. In each of the above embodiments, when a user wants to process a specific medium 99 from the multiple media 99 loaded on the stacker 14, the user sends a processing command to the processing system.

[0113] If the control unit 19 determines that the medium 99 is not to be processed based on the read data A1 and the index data A2, the control unit 19 may switch back the medium 99 from the processing path 16 to the stacker 14.

[0114] The technical concepts and effects that can be understood from the above-described embodiment and modified examples will be described below. (A) The processing system includes a stacker on which one or more media having images recorded thereon are loaded, a holding unit that holds the media, a processing path extending from the stacker toward the holding unit, a pick roller that transports the media from the stacker to the processing path, a reading unit that reads the media transported along the processing path, and a control unit that stores index data indicating whether or not to transport the media to the holding unit, and upon receiving a processing command from a user, the control unit causes the pick roller to transport the media from the stacker to the processing path, and determines whether or not to transport 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, when a processing command is received from a user, the control unit determines whether or not to transport the media from the stacker to the holding unit. This eliminates the risk of the media being automatically transported from the stacker to the holding unit against the user's intention, thereby improving the usability of the processing system.

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

[0117] According to the above configuration, the control unit can determine whether to transport the medium to the holding unit based on the image match rate. (C) The processing system may include a branch path branching off from the processing path, and the branch path may extend from a position on the processing path between the reading unit and the holding unit toward the stacker.

[0118] According to the above configuration, media that are determined not to be transported to the holding section are returned to the stacker via the branch path, which is convenient for the user. (D) The processing system may include a switchback roller located on the processing path between the holding section and a branch point where the branch path branches off, and the switchback roller may transport the medium from the processing path to the branch path by switching back the medium.

[0119] According to the above configuration, by transporting the media from the processing path to the branch path by the switchback, the media are reloaded in the stacker in the same orientation as when they were loaded in the stacker. In other words, if the media were loaded in the stacker with the recorded side facing upward, by transporting the media from the processing path to the branch path by the switchback, the media are reloaded in the stacker with the recorded side facing upward. In this way, the orientation of the media returned to the stacker does not change, making it easy for the user to use.

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

[0121] According to the above configuration, in the second mode, the reading unit does not read the medium, so the medium is transported to the holding unit in a shorter time than in the first mode, thereby improving the processing speed of the processing system.

[0122] (F) The processing system may include a detection sensor that detects media loaded on the stacker. According to the above configuration, the control unit can determine whether or not there are media stacked on the stacker by using 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 transports the media loaded in the stacker to the processing path in order, starting with the topmost medium. The topmost medium is not subjected to the weight of the other media. This makes it easier for the pick roller to transport the media from the stacker to the processing path.

[0124] (H) The processing system may include a moving mechanism for moving the stacker up and down. According to the above configuration, the movement mechanism can move the stacker up and down in accordance with the amount of media loaded in the stacker, which makes it easier for the pick roller to transport the media from the stacker to the processing path.

[0125] (I) In the above processing system, the pick roller may contact the lowest medium among the plurality of media loaded on the stacker. According to the above configuration, the pick roller transports the media loaded on the stacker to the processing path in order, starting with the lowest medium. The weight of the other media is applied to the lowest medium loaded on the stacker. As a result, the lowest medium of the media 99 loaded on the stacker 14 is pressed against the pick roller. This allows the pick roller to stably transport the media from the stacker to the processing path. [Explanation of symbols]
