The X, Y, and Z axes are orthogonal to each other. In the following description, the direction along the X-axis will also be referred to as the width direction X, the direction along the Y-axis as the depth direction Y, and the direction along the Z-axis as the vertical direction Z.

[0032] First Implementation Method

[0033] Overview of the recording device

[0034] like Figure 1 As shown, the recording device 11 includes a recording unit 20. The recording unit 20 records by ejecting liquid. The recording unit 20 records data on the medium M based on the recorded data. The recording device 11 is, for example, an inkjet printer that ejects ink onto the medium M to print characters and images.

[0035] The recording device 11 includes a main body 12, a reading unit 13, and an automatic feeding unit 14. The main body 12 is rectangular. The reading unit 13 and the automatic feeding unit 14 are mounted on the upper part of the main body 12. The recording device 11 has a configuration in which the main body 12, the reading unit 13, and the automatic feeding unit 14 are stacked sequentially from the bottom side in the vertical direction Z.

[0036] The reading unit 13 is configured to read characters, photographs, and other images recorded in the original document. The automatic feed unit 14 is configured to feed the original document to the reading unit 13. The reading unit 13 has an operation unit 15. The operation unit 15 is operated when an instruction from a user of the recording device 11 is provided to the recording device 11. The operation unit 15 has, for example, a touch panel-type LCD screen and operation buttons.

[0037] The operation unit 15 may also include an authentication unit 15a. The authentication unit 15a is, for example, an IC card reader. The IC card reader reads information stored in the integrated circuit within the IC card 92 located near the IC card reader. If the IC card 92 is the IC card of the user of the recording device 11, the authentication unit 15a authenticates the IC card 92. That is, if authenticated, the operations in the operation unit 15 can be performed.

[0038] The user, after placing the original document in the automatic feed unit 14, uses the operation unit 15 to give a reading instruction to the recording device 11, thereby causing the automatic feed unit 14 to feed the placed original document. Thus, the user can cause the reading unit 13 to read the image of the original document. Furthermore, by using the operation unit 15 to give a recording instruction to the recording device 11, the user can cause the medium M, recorded by the recording unit 20, to be discharged from the main body unit 12.

[0039] like Figure 1 As shown, the main body 12 has multiple media storage sections 16 capable of holding media M such as paper. In this embodiment, the main body 12 has a total of four media storage sections 16. The media storage sections 16 are configured to be pulled out relative to the main body 12. Furthermore, the main body 12 has a first discharge tray 17 on its upper part as a discharge tray for discharging the recorded media M. Alternatively, the number of media storage sections 16 may be only one.

[0040] The media M stored in the media receiving section 16 is conveyed to the first discharge tray 17. A feed roller (not shown) contacts and rotates the uppermost media M among the plurality of media M stored in the media receiving section 16, thereby feeding the uppermost media M from above the media receiving section 16. When the media M passes through a liquid ejector (not shown) on the recording section 20, the liquid ejector sprays liquid onto the media M, causing the sprayed liquid to adhere to the media M for recording. After recording, the media M is discharged from the main body 12 to the first discharge tray 17 via a discharge roller pair (not shown). The user can remove and retrieve the media M from the first discharge tray 17.

[0041] The recording device 11 may also include a post-processing device 90. For example, it may include a media loading device 50 that loads the recorded media M in units of copies and then discharges them as a media stack. In the media loading device 50, post-processing such as binding of the media stack may also be performed.

[0042] The recording device 11 may also include a conveying device 70 for conveying the recorded medium M to the media loading device 50. That is, the recording device 12 may be directly connected to the media loading device 50, or the recording device 12 may be connected to the media loading device 50 via the conveying device 70.

[0043] The recording device 11 may also include one or more processing devices different from the media loading device 50. For example, a folding device 80 may be further connected to the media loading device 50. The folding device 80 may also fold the media M delivered to the media loading device 50. In addition, the folding device 80 may also fold the stack of media loaded in the media loading device 50.

[0044] like Figure 1 As shown, the recording device 11 may also include multiple discharge trays 17, 57, and 58. The media loading device 50 includes a stacking tray 58 capable of loading a large quantity of media M and a second discharge tray 57. In the first discharge tray 17 of the main body 12, the media M is discharged with the recording side facing down. In the second discharge tray 57 of the media loading device 50, the media M is discharged with the recording side facing up. The user can remove and retrieve the media M from the second discharge tray 57 and the stacking tray 58.

[0045] The first row tray 17 and the second row tray 57 are spaced apart. The recording device 11 may also include... Figure 2 The third discharge tray 67 is shown. The third discharge tray 67 is spaced apart from the first discharge tray 17 and the second discharge tray 57. For example, the second conveyor and... Figure 1 The folding device 80 shown is connected at its position. Therefore, a second medium loading device can also be connected downstream of it. Thus, medium M can also be discharged into the third discharge tray 67 of the second medium loading device.

[0046] Regarding the composition of the recording device

[0047] like Figure 2As shown, the recording device 11 is connected to a network NW via wired or wireless means. The network NW is connected to multiple terminals 91 via wired or wireless means. Each terminal 91 is, for example, a personal computer, and includes an input unit 91a and a display unit 91b electrically connected to its main body. In the following description, a personal computer will be referred to simply as a PC. Furthermore, the terminal 91 is not limited to a PC; it can also be a tablet computer or a portable information terminal such as a smartphone. A recording driver program is installed in the terminal 91. Thus, the terminal 91 possesses a recording driver composed of software capable of sending recorded data to the recording device 11.

[0048] The recording device 11 includes a control unit 30 for controlling the recording device 11. The control unit 30 has a receiving unit 31 and a transmitting unit 32. The receiving unit 31 receives data transmitted via a network NW. The transmitting unit 32 transmits data via the network NW. The recording device 11 and the terminal 91 can transmit and receive data via a recording driver. The user of the operating terminal 91 sends recording data to the recording device 11 through the operation of the input unit 91a. When the receiving unit 31 receives the recording data sent by the user of the operating terminal 91, the transmitting unit 32 sends response data. By receiving the response data from the recording device 11, the user of the operating terminal 91 can confirm whether the recording data sent to the recording device 11 has been accepted by displaying on the display unit 91b.

[0049] The transmitting unit 32 sends information related to the recording device 11 to the terminal 91. The recording driver can also be configured such that, after the terminal 91 receives information related to the recording device 11 from the recording device 11, the terminal 91 sends recording data to the recording device 11. For example, the user operating the terminal 91 can also use the input unit 91a to input... Figure 2 When the recording device 11 shown is selected as the output destination for recorded data, the recording device 11 sends information related to the recording device 11 to the terminal 91. Furthermore, this information can also be displayed on the display unit 91b to notify the user operating the terminal 91. In other words, the recording device 11 can be configured to detect when a user intends to send recorded data to the recording device 11, and when the user intends to send recorded data, the control unit 30 sends information related to the recording device 11 to the terminal 91. Alternatively, the recording device 11 can send information related to the recording device 11 to the terminal 91 after the user has sent recorded data to the recording device 11.

[0050] like Figure 2As shown, the control unit 30 includes a computer 40. The control unit 30 causes the computer 40 to calculate the density near the recording device 11 (described later). The computer 40 has a storage unit 33. The storage unit 33 temporarily stores recording data sent from the user before recording. When the user of the operating terminal 91 sends recording data to the recording device 11, the recording data is stored in the storage unit 33. Furthermore, when recording data is stored in the storage unit 33, information related to the recording data is also stored in the storage unit 33 along with the recording data.

[0051] Information related to the recorded data includes, for example, the terminal 91 that sent the recorded data, the username that sent the recorded data, the date and time the recorded data was sent, and the discharge tray for discharging the medium M when it was being recorded. Information related to the recorded data also includes information related to the user who sent the recorded data stored in the storage unit 33. Furthermore, information related to the recorded data includes information calculated based on this information. For example, a first elapsed time can be calculated based on the date and time the recorded data was sent and the current date and time. That is, the elapsed time since the sending of each piece of recorded data is included in the information related to the recorded data. In the following description, "the elapsed time since the sending of each piece of recorded data" will be simply referred to as "first elapsed time." Furthermore, the first elapsed time is included in the information related to the recorded data.

[0052] When a user who has sent recording data brings their IC card 92 close to the authentication unit 15a, the IC card 92 is authenticated. Thus, the operation unit 15 can be used to give recording instructions to the recording device 11 from the previously sent recording data. The operation unit 15 is operated when recording data stored in the storage unit 33. By operating the operation unit 15, recording is performed on the medium M based on the recording data. Furthermore, the user's portable information terminal can also have the function of the IC card 92. Additionally, the user can also authenticate by entering their ID and password using the operation unit 15. After authentication, the recorded medium M is ejected from the main unit 12 in front of the user, thus preventing other users from accidentally taking back the user's medium M. Recorded data that has finished recording is deleted from the storage unit 33.

[0053] The user operating the terminal 91 can also simultaneously issue a recording instruction while sending recording data from the terminal 91, thereby immediately instructing the recording device 11 to record the medium M. In this case, recording to the medium M begins immediately in the recording device 11, and the recorded medium M is discharged from the main body 12. For example, the recorded medium M is discharged into the first discharge tray 17.

[0054] like Figure 2As shown, the computer 40 has a first prediction unit 34 and a second prediction unit 35. The first prediction unit 34 predicts a first recording time. The first recording time is the time required to record each piece of data. In the following description, the "time required to record each piece of data" will be simply referred to as the "first recording time". The second prediction unit 35 predicts a second recording time. The second recording time is the time required from the start of recording in the recording unit 20 until the end of the recording. In the following description, the "time required from the start of recording in the recording unit 20 until the end of the recording" will be simply referred to as the "second recording time".

[0055] The first prediction unit 34 predicts a first recording time when recorded data is saved to the storage unit 33 and saves it to the storage unit 33. The first recording time is included in information related to the recorded data. The second prediction unit 35 predicts a second recording time, for example, by subtracting the actual elapsed time during recording from the first recording time. For example, at the beginning of recording, the first recording time is saved as the second recording time in the storage unit 33, and as recording progresses, the second prediction unit 35 continuously updates the second recording time in the storage unit 33. The second recording time is also included in information related to the recorded data.

[0056] like Figure 2 As shown, the computer 40 has a storage unit 36 ​​for storing the recording history in the recording unit 20. When the recorded data is deleted from the storage unit 33 after recording has ended, a portion of the information associated with the recorded data is stored in the storage unit 36 ​​as the recording history of the recorded data. The information stored in the storage unit 33 that is associated with the recorded data includes the terminal 91 that sent the recorded data, the user who sent the recorded data, the date and time the recorded data was recorded on the medium M, the time required for recording the recorded data, and the ejection tray on which the medium M was ejected.

[0057] The first and second recording times are predicted values ​​for the time required thereafter, and therefore are no longer needed after the recording data has been actually recorded and the time required for recording the data has been determined. Therefore, the first and second recording times are information related to the recording data, but are not stored in the storage unit 36. The third recording time, which is the time required for recording the data when it was actually recorded, is stored in the storage unit 36. The third recording time is included in the information related to the recording data. In the following description, "the time required for recording the data when it was actually recorded" will be simply referred to as the "third recording time".

[0058] like Figure 2As shown, the computer 40 includes a calculation unit 37. The control unit 30 causes the calculation unit 37 to calculate the density near the recording device 11 based on information related to the recorded data stored in the storage unit 33. The density near the recording device 11 is defined as an index representing the magnitude of the number of people predicted to be gathered near the recording device 11. "Nearby" refers, for example, to the area within two meters around the recording device 11 when viewed from above. The control unit 30 causes the calculation unit 37 to calculate the magnitude of the number of people predicted to be gathered near the recording device 11. Furthermore, in this specification, the density near the recording device 11 will be simply referred to as "density".

[0059] For example, if it is predicted with a 1 / 2 probability that one person is gathered near the recording device 11, the predicted number of people gathered near the recording device 11 is 0.5. Since the predicted number of people is the expected value of the number of people gathered, this value does not have to be an integer. The density can be set as the same value as the predicted number of people, such as 0.5, or it can be set as the density after calculations such as multiplying the value by 100. In addition, the density can be classified into multiple categories according to the magnitude of the value, and each category can be set as the density. For example, the density can be classified into three categories according to the magnitude of the value, with the first category set as high density, the second category as medium density, and the third category as low density. That is to say, the density can be any index that represents the magnitude of the predicted number of people gathered near the recording device 11. In this embodiment, the predicted number of people gathered near the recording device 11 is set as the density. Furthermore, in the following description, "predicted number of people" will be simply referred to as "number of people".

[0060] When the density near the recording device 11 is not recorded with respect to a specific time, but only as the density near the recording device 11, it refers to the current density near the recording device 11. The density near the recording device 11 is included in the information related to the recording device 11. The method for calculating the density near the recording device 11 will be explained later.

[0061] like Figure 2As shown, the recording device 11 includes a conveying unit 19 that conveys the medium M stored in the medium storage unit 16 and discharges the recorded medium M from the main body 12 to the discharge tray 17. The recording device 11 includes a first detection unit 17a, which detects the medium M on the first discharge tray 17, which serves as the discharge tray. The first detection unit 17a continuously monitors the first discharge tray 17 and notifies the control unit 30 of the detection result of the medium M. That is, the first detection unit 17a can detect whether the medium M has been discharged from the first discharge tray 17. Alternatively, the first detection unit 17a can also be provided on the main body 12. For example, the first detection unit 17a can be provided on the outer wall of the main body 12 above the first discharge tray 17, allowing the detection of the presence of the medium M on the first discharge tray 17 from above.

[0062] The recording device 11 may also include a second detection unit 57a, which detects the medium M on the second discharge tray 57, which serves as a discharge tray. The second detection unit 57a continuously monitors the second discharge tray 57 and notifies the control unit 30 of the detection result of the medium M. That is, the second detection unit 57a can detect whether the medium M has been discharged from the second discharge tray 57.

[0063] The recording device 11 may also include a third detection unit 67a, which detects the medium M on the third discharge tray 67, which serves as a discharge tray. The third detection unit 67a continuously monitors the third discharge tray 67 and notifies the control unit 30 of the detection result of the medium M. That is, the third detection unit 67a can detect whether the medium M has been discharged from the third discharge tray 67. Furthermore, the recording device 11 may also include multiple discharge trays and a detection unit that detects the medium M on each discharge tray.

[0064] Methods for calculating density

[0065] like Figure 3 As shown, the flow of the density calculation method near the recording device 11 is executed by the computer 40 of the control unit 30. First, the overall flow of the density calculation method near the recording device 11 will be explained, and then the subroutines for calculating the number of people in each step will be explained.

[0066] People gather near the recording device 11 for various purposes. They gather to record data stored in the storage unit 33 after being sent from the terminal 91. They also gather to retrieve the medium M that has been ejected from the main unit 12. Furthermore, they gather near the recording device 11 to allow the reading unit 13 to read images of the original placed in the automatic feed unit 14, or to copy the original placed in the automatic feed unit 14 to the medium M on the spot. The control unit 30 instructs the calculation unit 37 to sum the number of people gathered near the recording device 11 for their respective purposes, thereby calculating the total number of people gathered near the recording device 11. In this embodiment, the control unit 30 sets the predicted number of people gathered near the recording device 11 as the density of the area near the recording device 11.

[0067] This process includes: calculating the number of people gathered to record data; calculating the number of people gathered to retrieve the discharged medium M; and calculating the number of people currently using the recording device 11. Furthermore, this process includes a step of calculating the density near the recording device 11 by summing these calculated numbers.

[0068] In step S200, the control unit 30 instructs the calculation unit 37 to calculate the number of people gathered for recording data. More specifically, a subroutine is executed to calculate the number of users gathered at the recording device 11 for recording the data stored in the storage unit 33 to the medium M and retrieving it. When the subroutine ends, the control unit 30 transfers the processing to step S300.

[0069] In step S300, the control unit 30 instructs the calculation unit 37 to calculate the number of people gathered to retrieve the discharged media M. More specifically, a subroutine is executed to calculate the number of users gathered at the recording device 11 to retrieve the media M discharged to the first discharge tray 17, the second discharge tray 57, and the third discharge tray 67. When the subroutine ends, the control unit 30 transfers the processing to step S400.

[0070] In step S400, the control unit 30 instructs the calculation unit 37 to calculate the number of people currently using the recording device 11. Users may also use the recording device 11 to allow the reading unit 13 to read images of originals placed on the automatic feed unit 14. Additionally, users may use the recording device 11 to copy originals placed on the automatic feed unit 14 to the medium M on the spot. A subroutine is executed to calculate the number of users currently using the recording device 11 by performing these operations.

[0071] When the processing in step S400 ends, in step S101, the control unit 30 instructs the calculation unit 37 to calculate the density near the recording device 11. The density near the recording device 11 is calculated by adding the number of people gathered to record data, the number of people gathered to retrieve the discharged medium M, and the number of people currently using the recording device 11. The process ends when the density is calculated.

[0072] This process is repeatedly executed by the control unit 30. For example, the number of people calculated in step S200 is calculated based on information related to the recorded data. Therefore, this process is executed whenever at least one piece of information related to the recorded data is updated. In addition, this process is also executed when new recorded data is saved to the storage unit 33 and when recorded data that has ended is deleted from the storage unit 33. In other words, the density near the recording device 11 is continuously updated to the latest value by the control unit 30.

[0073] The control unit 30 calculates the density based on information related to the recorded data stored in the storage unit 33, and sets the calculated density to a state that can be referenced by the user. For example, the recording device 11 can be configured via a recording drive to allow access to information related to the recording device 11 from the terminal 91, so that the user can reference the density near the recording device 11 on the display unit 91b. Furthermore, the recording device 11 can also be configured to detect when the user intends to send recorded data to the recording device 11. Moreover, when the user intends to send recorded data to the recording device 11, the control unit 30 can also notify the user of the current density.

[0074] In this process, step S200, which calculates the number of people gathered to record the data, may be omitted. That is, this process may also consist of steps S300, S400, and S101. For example, the operation unit 15 may not have an authentication unit 15a. When the user of the operation terminal 91 sends the recording data from the terminal 91, they simultaneously issue a recording instruction, thereby immediately starting recording on the medium M and discharging the recorded medium M from the main body 12. Therefore, the person using the recording device 11 and the person who retrieved the discharged medium M are gathered at the recording device 11.

[0075] In this process, step S300, which calculates the number of people gathered to retrieve the discharged medium M, may be omitted. That is, this process may also consist of steps S200, S400, and S101. For example, the recording device 11 may be configured such that, instead of issuing a recording instruction simultaneously when sending recording data from the terminal 91, the medium M to be recorded must be discharged from the main body 12 by issuing a recording instruction via the authentication unit 15a. Therefore, the recording device 11 is occupied by people who record recording data and people who use the recording device 11.

[0076] In this process, step S400, which calculates the number of people currently using the recording device 11, may be omitted. That is, this process may also consist of steps S200, S300, and S101. For example, the recording device 11 may not have a reading unit 13 and an automatic feeding unit 14. Therefore, the recording device 11 is occupied by people who record data and people who retrieve the discharged medium M.

[0077] This process can also consist of steps S200 and S101. Alternatively, this process can also consist of steps S300 and S101. Furthermore, this process can also consist of steps S400 and S101.

[0078] Calculation of the number of people gathered for recording data.

[0079] like Figure 4 As shown, the computer 40 of the control unit 30 executes a subroutine to calculate the number of people gathered for recording data. This subroutine includes a step of selecting recording data based on information related to the user who sent the recording data, and a step of calculating the value of the number of people gathered for recording data based on information related to the selected recording data.

[0080] In step S500, the computer 40 of the control unit 30 executes a subroutine to select record data for counting the number of people. This subroutine is a step of selecting record data based on information related to the user who sent the record data. When this subroutine ends, the control unit 30 transfers the processing to step S600.

[0081] In step S600, the computer 40 of the control unit 30 executes a subroutine for calculating the number of people. This subroutine is a step of calculating the number of people gathered for recording data based on information related to the selected recording data. In other words, this subroutine is a step of calculating density based on information related to the selected recording data. When this subroutine ends, the control unit 30 terminates the subroutine for calculating the number of people gathered for recording data.

[0082] like Figure 5 As shown, the computer 40 of the control unit 30 executes a subroutine to select recording data for calculating the number of people gathered to record the data. This subroutine is a step of selecting recording data based on information related to the user who sent the recording data. The control unit 30 selects the recording data for calculating the number of people gathered to record the data based on information related to the user who sent the recording data. In other words, in the process of calculating the density near the recording device 11, the control unit 30 selects the recording data for calculating the density near the recording device 11 based on information related to the user who sent the recording data.

[0083] In step S501, the control unit 30 excludes recording data for which the user who sent the recording data is not currently present. That is, it selects recording data for which the user who sent the recording data is not currently present. Even if the recording data is stored in the storage unit 33, people may not necessarily gather to record that data. For example, there may be a situation where, when recording data is sent from a distant user using a portable information terminal, the recording data is not recorded immediately, but rather recorded using the recording device 11 when the user returns from the distance. That is, recording data can also be selected based on the location information of the portable information terminal of the user who sent the recording data. For example, even if the recording data is stored in the storage unit 33, if the user who sent the recording data is not present today, the recording data will not be recorded today. That is, recording data can also be selected based on information about whether the user who sent the recording data is not present today. The location information of the portable information terminal of the user who sent the recording data and the information about whether the user who sent the recording data is not present today are examples of information related to the user who sent the recording data stored in the storage unit 33. When the processing of step S501 is completed, the control unit 30 transfers to the processing of step S502.

[0084] In step S502, the control unit 30 excludes the recorded data of users who are notified of the density. That is, it selects the recorded data of users who are notified of the density. The recorded data used to calculate the number of people gathered to record the data can also vary depending on the user. Since the people gathered by a user to record the data stored in the storage unit 33 are the user themselves, the recorded data of users who are notified of the density stored in the storage unit 33 are selected. In other words, the control unit 30 calculates the density that can be referenced by each user based on information related to the recorded data that excludes the recorded data of each user. When the processing of step S502 ends, the control unit 30 terminates the subroutine.

[0085] like Figure 6 As shown, the computer 40 of the control unit 30 executes a subroutine to calculate the number of people gathered for recording data. The control unit 30 causes the calculation unit 37 to... Figure 5 The subroutine shown predicts the number of people who would gather to record the selected record data, and sums these numbers to calculate the total number of people gathered to record the record data. This subroutine is the step of calculating density based on information associated with the selected record data.

[0086] In step S601, the control unit 30 instructs the calculation unit 37 to calculate a first elapsed time for each selected record data. The first elapsed time is calculated based on the date and time the record data was sent, as well as the current date and time. When the processing of step S601 ends, the control unit 30 proceeds to the processing of step S602.

[0087] In step S602, the control unit 30 causes the first prediction unit 34 to predict the first recording time for each selected piece of recording data. For example, the first prediction unit 34 predicts the first recording time based on the recording density when printing the recording data, the size of the medium M, and whether it is double-sided or single-sided recording. The first recording time is included in the information related to the recording data. The first recording time can also be an estimated value, for example, it can be predicted in minutes. When the processing of step S602 ends, the control unit 30 proceeds to the processing of step S603.

[0088] In step S603, the control unit 30 causes the calculation unit 37 to calculate the number of people for each recorded data based on the number table based on the first elapsed time and the first recorded time. Figure 7 The table shown is an example of a headcount table based on the first elapsed time and the first recorded time. When the processing of step S603 ends, the control unit 30 transfers to the processing of step S604.

[0089] In step S604, the control unit 30 adds up the number of people gathered to record each piece of data. The value obtained by adding up these numbers is the number of people gathered at the recording device 11 to record the data.

[0090] like Figure 7 As shown, the number of people gathered at the recording device 11 to record data is calculated based on the first elapsed time. Furthermore, the number of people gathered at the recording device 11 to record data is calculated based on the first recording time. Additionally, Figure 7 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Additionally, the time divisions can be set appropriately. Furthermore, a formula can be used to calculate the number of people gathered at the recording device 11 for recording data by substituting the first elapsed time and the first recording time.

[0091] It can also be adjusted based on information related to the user who sent the recorded data. Figure 7 The values ​​recorded in the table shown. That is, the control unit 30 can also calculate the density based on information related to the users who sent the recording data by adjusting the values ​​recorded in the number table based on the first elapsed time and the first recording time. For example, in the recording data of users who immediately gather at the recording device 11 after sending the recording data, the value of the number of people in the first elapsed time hour can be increased. Figure 7The values ​​recorded in the table shown. For example, by analyzing the recording history over multiple days, users who immediately gathered at the recording device 11 after the recording data was sent can be identified.

[0092] The longer the first elapsed time, the lower the frequency of data gathering at the recording device 11 in order to record the data. Therefore, it is best to set the value as small as the first elapsed time is longer. In addition, since the longer the first recording time, the longer the time it takes for data to gather at the recording device 11 in order to record the data, it is best to set the value as large as the first recording time is longer.

[0093] like Figure 8 As shown, the number of people gathered at the recording device 11 for recording data can also be calculated based on the amount of recorded data stored in the storage unit 33, without using the first elapsed time and the first recording time. In other words, in the process of calculating the density near the recording device 11, the control unit 30 can also calculate the density based on the amount of recorded data stored in the storage unit 33. Furthermore, Figure 8 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Additionally, the number of people gathered at the recording device 11 to record data can be calculated based on the number of users who have sent the recorded data stored in the storage unit 33. In other words, in the process of calculating the density near the recording device 11, the control unit 30 can also calculate the density based on the number of users in the recorded data stored in the storage unit 33.

[0094] Calculation of the number of people gathered to retrieve the discharged medium.

[0095] like Figure 9 As shown, the computer 40 of the control unit 30 executes a subroutine to calculate the number of people gathered to retrieve the discharged media M. This subroutine includes a step of selecting a discharge tray for calculating the number of people based on information related to a user who sent recorded data of the media M discharged to discharge trays 17, 57, and 67. Furthermore, this subroutine includes a step of calculating the number of people gathered to retrieve the discharged media M based on information related to the media M discharged to the selected discharge tray.

[0096] In step S700, the control unit 30 executes a subroutine to select the discharge tray for counting the number of people. This subroutine is a step of selecting the discharge tray for counting the number of people based on information related to the user who sent the recorded data of the medium M discharged to the discharge trays 17, 57, 67. Figure 2The recording device 11 shown has three discharge trays 17, 57, and 67. The three discharge trays are a first discharge tray 17, a second discharge tray 57, and a third discharge tray 67. In step S700, the control unit 30 selects one or more of the first discharge tray 17, the second discharge tray 57, and the third discharge tray 67. Alternatively, all discharge trays can be selected. When the subroutine ends, the control unit 30 transfers the processing to step S800.

[0097] In step S800, the control unit 30 executes a subroutine for calculating the number of people. This subroutine is a step of calculating the number of people gathered to retrieve the discharged medium M based on information related to the medium M discharged to the selected discharge tray. When this subroutine ends, the control unit 30 terminates the subroutine for calculating the number of people gathered to retrieve the discharged medium M.

[0098] like Figure 10 As shown, the computer 40 of the control unit 30 executes a subroutine to select the discharge tray for calculating the number of people gathered to retrieve the discharged medium M. The control unit 30 selects the discharge tray for calculating the number of people gathered to retrieve the discharged medium M based on information related to the user who sent the recorded data of the medium M discharged to that discharge tray. In other words, in the process of calculating the density near the recording device 11, the control unit 30 selects the recording data for calculating the density near the recording device 11 based on information related to the user who sent the recorded data.

[0099] In step S701, the control unit 30 excludes discharge trays where the user who discharged the medium M is not currently present. That is, it selects discharge trays where the user who discharged the medium M is not currently present. Even if the medium M is discharged to a discharge tray, people may not gather to retrieve it. For example, there may be a situation where the medium M is not immediately retrieved when the user is not at the office where the recording device 11 is installed, but is retrieved when the user returns to the office. For example, the discharge tray can also be selected based on the location information of the portable information terminal owned by the user who sent the recording data of the medium M discharged to the discharge tray. For example, if the user who sent the recording data of the medium M is not present on that day, the medium M will not be retrieved that day. That is, the discharge tray can also be selected based on whether the user who sent the recording data of the medium M discharged to the discharge tray is present on that day. The location information of the portable information terminal of the user who sent the recording data and the information on whether the user who sent the recording data is present on that day are examples of information related to the user who sent the recording data of the medium M discharged to the discharge tray. When the processing of step S701 is completed, the control unit 30 transfers to the processing of step S702.

[0100] In step S702, the control unit 30 excludes discharge trays from which users who have been notified of a certain density of discharge have discharged the medium M. That is, it selects discharge trays from which users who have been notified of a certain density of discharge have discharged the medium M. The discharge trays used to calculate the number of people gathered to retrieve the discharged medium M can also vary depending on the number of users near the recording device 11 that have been notified of the calculated density. Since the people gathered by a user to retrieve the medium M that has been discharged to the discharge tray are that user himself, the discharge trays from which users who have been notified of a certain density of discharge have discharged the medium M are selected. When the processing of step S702 ends, the control unit 30 terminates the subroutine.

[0101] like Figure 11 As shown, the computer 40 of the control unit 30 executes a subroutine to calculate the number of people gathered to retrieve the discharged medium M. The control unit 30 targets... Figure 10 The subroutine shown predicts the number of people who will gather to retrieve the medium M that has been discharged to the discharge tray for each selected tray. Furthermore, the control unit 30 adds up these numbers, thereby enabling the calculation unit 37 to calculate the number of people who will gather to retrieve the discharged medium M.

[0102] In step S801, the control unit 30 refers to the detection results of the detection units 17a, 57a, and 67a provided in each of the selected discharge trays 17, 57, and 67. The detection results of each detection unit 17a, 57a, and 67a are included in information related to the medium M discharged to the selected discharge trays 17, 57, and 67. When the processing of step S801 ends, the control unit 30 proceeds to the processing of step S802.

[0103] In step S802, the control unit 30 instructs the calculation unit 37 to calculate a second elapsed time for each selected discharge tray. This second elapsed time is the time elapsed since the medium M was discharged onto the discharge tray. In the following description, the "time elapsed since the medium M was discharged onto the discharge tray" will be simply referred to as the "second elapsed time." The second elapsed time is calculated based on the date and time the medium M was discharged onto the discharge tray, as well as the current date and time. When the processing of step S802 ends, the control unit 30 proceeds to the processing of step S803.

[0104] In step S803, the control unit 30 causes the calculation unit 37 to calculate the number of people for each discharge tray based on the number of people table based on the second elapsed time. Figure 12 The table shown is an example of a headcount table based on the second elapsed time. When the processing of step S803 ends, the control unit 30 transfers to the processing of step S804.

[0105] In step S804, the control unit 30 adds up the number of people who have gathered to retrieve the discharged media M from each discharge tray. The value obtained by adding up these numbers is the number of people who have gathered at the recording device 11 to retrieve the discharged media M.

[0106] like Figure 12 As shown, the number of people gathered at the recording device 11 to retrieve the discharged medium M is calculated based on the detection results of detection units 17a, 57a, and 67a. In other words, in the process of calculating the density near the recording device 11, the control unit 30 calculates the density near the recording device 11 based on the detection results of the medium M in detection units 17a, 57a, and 67a. Furthermore, the number of people gathered at the recording device 11 to retrieve the discharged medium M is calculated based on a second elapsed time. In other words, in the process of calculating the density near the recording device 11, the control unit 30 calculates the density near the recording device 11 based on a second elapsed time. The second elapsed time is the elapsed time after the medium M is discharged onto the discharge trays 17, 57, and 67. Moreover, Figure 12 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Furthermore, the time division can also be set appropriately. Additionally, by substituting the values ​​of the second elapsed time and the detection results of detection units 17a, 57a, and 67a, a formula can be used to calculate the number of people who have gathered at the recording device 11 to retrieve the discharged medium M. For example, in the detection results of detection units 17a, 57a, and 67a, the value when detected is set to 1, and the value when not detected is set to zero.

[0107] Since the longer the second elapsed time, the lower the frequency of people gathering at the recording device 11 to record data, it is best to set the value as low as the second elapsed time is. For example, there is a possibility that users may forget to save the recorded data to the storage unit 33 because they are busy with other tasks. In addition, since the sensors used in the detection units 17a, 57a, and 67a have high detection accuracy, it is best to set the value of the number of people gathering at the recording device 11 to retrieve the discharged medium M to zero when no detection is being performed.

[0108] Calculation of the number of people currently using the recording device

[0109] like Figure 13As shown, the computer 40 of the control unit 30 executes a subroutine to calculate the number of people currently using the recording device 11. This subroutine includes a step of calculating the number of people currently using the recording device 11 based on whether each part of the recording device 11 is in operation. In this embodiment, the parts of the recording device 11 include, for example, the operation unit 15, the reading unit 13, and the recording unit 20. Furthermore, this subroutine may also include a step of calculating the number of people currently using the recording device 11 based on whether the post-processing device 90, including the media loading device 50 and the folding device 80, is in operation.

[0110] In step S401, the control unit 30 determines whether the operation unit 15 is in operation. When the operation unit 15 is in operation, step S401 is "yes", and the control unit 30 transfers the processing to step S402. When the operation unit 15 is not in operation, step S401 is "no", and the control unit 30 transfers the processing to step S403.

[0111] In step S402, the control unit 30 sets the value of the number of people currently using the recording device 11 to 1. In other words, in the process of calculating the density near the recording device 11, the control unit 30 calculates the density near the recording device 11 based on the operation status of the operation unit 15. When the value of the number of people currently using the recording device 11 is 1, the recording device 11 is in the state where one user is using the operation unit 15. The control unit 30 ends the subroutine.

[0112] In step S403, the control unit 30 determines whether the reading unit 13 or the automatic feed unit 14 is in operation. When the reading unit 13 or the automatic feed unit 14 is in operation, step S403 is "yes", and the control unit 30 transfers the processing to step S404. When neither the reading unit 13 nor the automatic feed unit 14 is in operation, step S403 is "no", and the control unit 30 transfers the processing to step S405.

[0113] In step S404, the control unit 30 sets the value of the number of people currently using the recording device 11 to 1. In other words, in the process of calculating the density near the recording device 11, the control unit 30 calculates the density near the recording device 11 based on the operation status of the reading unit 13 or the automatic feed unit 14. When the value of the number of people currently using the recording device 11 is 1, the recording device 11 is in a state where a certain user is using the reading unit 13 or the automatic feed unit 14. For example, it is in a state where a certain user is performing an operation to read text, photos, or other images recorded in an original document. The control unit 30 ends the subroutine.

[0114] In step S405, the control unit 30 determines whether the recording unit 20 or the conveying unit 19 is in operation. When the recording unit 20 or the conveying unit 19 is in operation, step S405 is "yes", and the control unit 30 transfers the process to step S406. When neither the recording unit 20 nor the conveying unit 19 is in operation, step S405 is "no", and the control unit 30 transfers the process to step S409.

[0115] In step S409, the control unit 30 sets the number of people currently using the recording device 11 to zero. That is, since none of the components in the recording device 11 are operating, the number of people currently using the recording device 11 is 0. The control unit 30 then terminates the subroutine.

[0116] In step S406, when the recording unit 20 or the transport unit 19 is in operation, the control unit 30 determines whether the recording device 11 is operating according to a recording instruction from the terminal 91. If the recording device 11 is operating according to a recording instruction from the terminal 91, step S406 is "yes", and the control unit 30 transfers the process to step S407. If the recording device 11 is operating according to a recording instruction from the operation unit 15 or the authentication unit 15a, step S405 is "no", and the control unit 30 transfers the process to step S410.

[0117] In step S410, the control unit 30 sets the number of people currently using the recording device 11 to 1. That is, since the person who started recording with the recording device 11 through the operation unit 15 or the authentication unit 15a is in a state of waiting for the recording to end, the number of people using the recording device 11 is 1. The control unit 30 ends the subroutine.

[0118] In step S407, the control unit 30 causes the first prediction unit 34 to predict a second recording time based on the recording data in the current record. The second recording time is included in information related to the recording data. When the processing of step S407 ends, the control unit 30 proceeds to the processing of step S408.

[0119] In step S408, the control unit 30 causes the calculation unit 37 to calculate the number of people currently using the recording device 11 based on the number table based on the second recording time. Figure 14 The table shown is an example of a people count table based on a second recording time. For example, after the first recording time is saved as the second recording time in the storage unit 33 at the beginning of recording, the second prediction unit 35 subtracts the elapsed time from the second recording time as recording progresses. That is, the second prediction unit 35 continuously updates the second recording time in the storage unit 33. Therefore, as recording progresses, the control unit 30 continuously updates the number of people currently using the recording device 11.

[0120] like Figure 14 As shown, the number of people currently using the recording device 11 is calculated based on the second recording time. Furthermore, Figure 14 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Additionally, the time division can be set appropriately. Furthermore, a formula can be used to calculate the number of people currently using the recording device 11 by substituting the second recording time. Moreover, since the shorter the second recording time, the higher the frequency of immediately retrieving the medium M discharged to the recording device 11, it is best to set the value to be larger for a shorter second recording time.

[0121] Configuration includes calculation of the density of each zone of the discharge tray.

[0122] The control unit 30 can also divide the area around the recording device 11 into multiple regions and calculate the density for each region. For example, the control unit 30 can also calculate the density for each region where each discharge tray is configured. Figure 1 At the recording device 11 shown, there are people gathered near the main body 12 including the first discharge tray 17 and people gathered near the post-processing device 90 including the second discharge tray 57. Since the first discharge tray 17 and the second discharge tray 57 are spaced apart, the risk of infection due to contact or proximity between the two is small. Therefore, both the density of the area where the first discharge tray 17 is disposed and the density of the area where the second discharge tray 57 is disposed can be calculated. For example, the density of the area where the first discharge tray 17 is disposed can be taken as the first density near the recording device 11, and the density of the area where the second discharge tray 57 is disposed can be taken as the second density near the recording device 11.

[0123] The first density near the recording device 11 is calculated based on information related to the recorded data destined for the first discharge tray 17 and the operational status of each part of the main body 12 including the first discharge tray 17. Additionally, the second density near the recording device 11 is calculated based on information related to the recorded data destined for the second discharge tray 57 and the operational status of each part of the post-processing device 90 including the second discharge tray 57.

[0124] When the user of the operating terminal 91 uses the input section 91a to... Figure 2 When the recording device 11 shown is selected as the output destination for recorded data, the recording device 11 can also send the density of the area near the recording device 11 to the terminal 91. Additionally, at this time, the recording device 11 can also send the density of the areas within the recording device 11 where each discharge tray is configured to the terminal 91 to the terminal 91. That is, the user operating the terminal 91 can also be notified of the first density and the second density of the area near the recording device 11. The user can refer to these density values ​​to select the discharge tray as the discharge destination.

[0125] Alternatively, the user of the operating terminal 91 can use the input unit 91a to input... Figure 2 When the recording device 11 is selected as the output destination for the recorded data, it automatically selects the discharge tray configured in the area with the lowest density among the areas where each discharge tray is configured as the discharge destination. That is, after the recorded data is sent from the terminal 91 to the recording device 11, the recording device 11 can also select the discharge tray configured in the area with the lowest density among the areas where each discharge tray is configured as the discharge destination and discharge the medium M.

[0126] The role of the implementation method

[0127] The function of this embodiment will be explained.

[0128] When a user of the operating terminal 91 sends recording data to the recording device 11, the recording data is saved to the storage unit 33. At this time, information associated with the recording data, such as the terminal 91 that sent the recording data, the username that sent the recording data, the date and time of sending the recording data, and the discharge tray discharged by the supplied medium M, are also saved to the storage unit 33. The storage unit 33 stores recording data sent from multiple users and the information associated with the recording data. Furthermore, recording data that has been recorded is deleted from the storage unit 33.

[0129] If a user who sent the recording data possesses IC card 92, and brings IC card 92 close to the authentication unit 15a, IC card 92 is authenticated. Thus, the operation unit 15 can be used to give a recording instruction to the recording device 11 from the previously sent recording data. The user whose IC card 92 is authenticated can operate the operation unit 15 to record on the medium M based on the recording data sent by that user.

[0130] By excluding the record data of users who sent the record data and the record data of users who were notified of the density from the record data of the density calculation object, the accuracy of the number of people gathered at the recording device 11 for the purpose of recording the record data can be improved.

[0131] The control unit 30 instructs the calculation unit 37 to calculate the first elapsed time for each record data stored in the storage unit 33, based on the date and time the record data was sent and the current date and time. The calculation unit 37 continuously updates the value of the first elapsed time as time passes.

[0132] The control unit 30 calculates the number of people gathered at the recording device 11 to record the data based on a first elapsed time, which is the time elapsed since each piece of recording data was sent. Therefore, the density value can be increased immediately after the recording data is sent. That is, when the frequency of people gathering at the recording device 11 to record the data is high, the density value can be increased.

[0133] The control unit 30 calculates the density based on the time required to record the data, i.e., the first recording time. Therefore, when the time required to record the data is long, the density value can be increased. That is, when the frequency of data being gathered at the recording device 11 for recording is high, the density value can be increased.

[0134] Users who do not possess IC card 92 can immediately initiate recording by sending recording data from terminal 91 by simultaneously issuing a recording instruction. Furthermore, the recorded medium M can be discharged from main body 12. For example, the recorded medium M is discharged to first discharge tray 17, and the medium M discharged to first discharge tray 17 is detected by first detection unit 17a.

[0135] The control unit 30 excludes discharge trays from the calculation objects that contain media M that the user who discharged the media M is not currently present, and discharge trays from which users who have been notified of the density of discharge have discharged the media M. This improves the accuracy of calculating the number of people gathered at the recording device 11 to retrieve the discharged media M.

[0136] The control unit 30 causes the calculation unit 37 to calculate the second elapsed time for each discharge tray based on the date and time when the medium M is discharged onto the discharge tray, as well as the current date and time. The calculation unit 37 continuously updates the value of the second elapsed time as time passes.

[0137] The control unit 30 instructs the calculation unit 37 to calculate the number of people gathered at the recording device 11 to retrieve the discharged medium M based on the detection results of the medium M in the detection units 17a, 57a, and 67a. The control unit 30 also instructs the calculation unit 37 to calculate the number of people gathered at the recording device 11 to retrieve the discharged medium M based on the elapsed time after the medium M is discharged onto the discharge trays 17, 57, and 67, i.e., the second elapsed time. Therefore, the density value can be increased when the medium M is just discharged onto the discharge trays 17, 57, and 67 of the recording device 11. That is, when the frequency of people gathering at the recording device 11 to retrieve the discharged medium M is high, the density value can be increased.

[0138] The user can operate the operation unit 15 to cause the reading unit 13 to read the image of the original document placed on the automatic feed unit 14. In addition, the user can operate the operation unit 15 to copy the original document placed on the automatic feed unit 14 to the medium M on the spot.

[0139] The control unit 30 instructs the calculation unit 37 to calculate the number of people currently using the recording device 11 based on whether each component of the recording device 11 is in operation. Therefore, when each component of the recording device 11 is in use, the value of the number of people currently using the recording device 11 can be increased.

[0140] The calculation unit 37 adds up the number of people gathered at the recording device 11 to record the data, the number of people gathered at the recording device 11 to retrieve the discharged medium M, and the number of people currently using the recording device 11, thereby calculating the density near the recording device 11.

[0141] When a user wants to send recorded data from the terminal 91, the control unit 30 notifies the terminal 91 of the current density. This allows the user to know the density near the recording device 11. The control unit 30 divides the vicinity of the recording device 11 into multiple regions and calculates the density for each region. Furthermore, it notifies the terminal 91 of these densities. This avoids using the recording device 11 in areas with high density.

[0142] Effects of the implementation method

[0143] The effects of this implementation method will be explained.

[0144] The following effects can be obtained in the recording device 11 and the density calculation method near the recording device 11 in this embodiment.

[0145] (1) When the density near the recording device 11 is set as an index representing the magnitude of the number of people predicted to be gathered near the recording device 11, the control unit 30 calculates the density based on information related to the recorded data stored in the storage unit 33. Furthermore, the control unit 30 makes this density a state that can be referenced by the user. Since the user can refer to the density near the recording device 11 and use the value of this density as a reference to decide whether to go to the recording device 11, the frequency of contact or approach to people gathered near the recording device 11 can be reduced.

[0146] (2) Information related to the recorded data includes information related to the user who sent the recorded data stored in the storage unit 33. By calculating the density based on the information related to the user who sent the recorded data stored in the storage unit 33, the frequency of contact or proximity to people who are highly likely to come to the recording device 11 to retrieve the medium M can be reduced.

[0147] (3) The control unit 30 selects the recorded data used for density calculation based on information related to the user who sent the recorded data. Thus, when calculating density based on information related to the recorded data, the accuracy of density calculation can be improved by removing the recorded data of people who are unlikely to receive the medium M from the recording device 11.

[0148] (4) The control unit 30 calculates the density that can be referenced by each user based on information related to the record data excluding that user's record data. When calculating the density for each user based on information related to the record data, the accuracy of the density calculation can be improved by removing the record data sent by that user.

[0149] (5) When a user wants to send recording data, the control unit 30 sends the current density to the user. By notifying the user of the current density, the user who wants to record using the recording device 11 can determine whether they should immediately send the recording data to the recording device 11. In addition, by notifying the current density, the user can determine whether they should immediately go to the recording device 11 to record to the medium M after sending the recording data.

[0150] (6) Information related to the recorded data includes the first elapsed time as the time elapsed since the transmission of each piece of recorded data. Therefore, the frequency of contact or proximity to a person who comes to the recording device 11 immediately after transmitting the recorded data to the recording device 11 in order to record the recorded data to the medium M can be reduced.

[0151] (7) Information related to the recorded data includes the first recording time, which is the time required to record the recorded data. Therefore, the frequency of contact or proximity to people who spend a long time recording data to the medium M using the recording device 11 can be reduced.

[0152] (8) The control unit 30 calculates the density based on the amount of recorded data stored in the storage unit 33. Therefore, the recording device 11 can be used outside of the time when it is frequently used.

[0153] (9) The control unit 30 calculates the density based on the operation status of the operation unit 15 when recording data stored in the storage unit 33. Therefore, the frequency of contact or approach to the operation unit 15 of the recording device 11 can be reduced.

[0154] (10) The control unit 30 calculates the density based on the detection results of the medium M in the detection units 17a, 57a, 67a and the second elapsed time after the medium M is discharged onto the discharge trays 17, 57, 67. Therefore, the frequency of contact or proximity to a person who immediately comes to pick up the medium M located on the discharge trays 17, 57, 67 of the recording device 11 can be reduced.

[0155] (11) Information related to the recorded data includes a second recording time, which is the time required from the start of recording in the recording unit 20 until the end of the recording. Therefore, the frequency of contact or proximity to a person who comes to collect the medium M to be discharged by the recording made using the recording device 11 can be reduced.

[0156] (12) The control unit 30 divides the area around the recording device 11 into multiple regions and calculates the density for each region. Therefore, it is possible to avoid using the recording device 11 in areas with high density.

[0157] (13) The control unit 30 calculates the density for each area where each discharge tray 17, 57, 67 is configured, and selects the discharge tray in the area with the lowest density in that area as the discharge destination and discharges the medium M. Therefore, the frequency of contact or proximity between the user and people gathered near the recording device 11 when going to the discharge tray to retrieve the medium M can be reduced.

[0158] Second Implementation Method

[0159] Hereinafter, the second embodiment will be described with reference to the accompanying drawings. Since the second embodiment is substantially the same as the first embodiment, repeated descriptions are omitted by referring to the same components with the same reference numerals.

[0160] In this embodiment, the control unit 30 calculates the density near the recording device 11 based on the recording history stored in the storage unit 36, and sets the calculated density to a state that can be referenced by the user. For example, the density near the recording device 11 is calculated based on yesterday's recording history.

[0161] Methods for calculating density

[0162] like Figure 15 As shown, the process of executing the density calculation method near the recording device 11 by the computer 40 of the control unit 30 includes the steps of selecting a recording history for calculating the density near the recording device 11 and calculating the density near the recording device 11 based on the selected recording history.

[0163] In step S1100, the control unit 30 executes a subroutine to select the recording history used for calculating the density. This subroutine is a step of selecting the recording history based on information related to the user who sent the recording data in the recording history and the time period when the recording data in the recording history was recorded. When this subroutine ends, the control unit 30 transfers the processing to step S1200.

[0164] In step S1200, the control unit 30 executes a subroutine to calculate the number of people gathered near the recording device 11. In this embodiment, the number of people gathered near the recording device 11 is defined as the density. This subroutine is a step of calculating the density near the recording device 11 based on the selected recording history. When this subroutine ends, the process of calculating the density near the recording device 11 is terminated by the control unit 30.

[0165] like Figure 16 As shown, the computer 40 of the control unit 30 executes a subroutine to select the recording history used for calculating density. The control unit 30 selects the recording history used for calculating density based on information related to the user who sent the recording data in the recording history and the time period when the recording data in the recording history was recorded.

[0166] In step S1101, the control unit 30 excludes the recording history of users who will receive notifications of high density. That is, it selects the recording history that will exclude the recording history of users who will receive notifications of high density. This step is a step of selecting the recording history based on information related to the users who sent the recording data in the recording history. When the processing of step S1101 ends, the control unit 30 transfers to the processing of step S1102.

[0167] In step S1102, recorded history outside the specified time period is excluded. For example, a day is divided into 24 time periods by hour. For example, if the current time is 9:30, the current time belongs to the "9:00 to 10:00" time period. The time division can also be set appropriately. That is, when calculating the density in the current time period, recorded history whose recorded data was recorded in the time period that matches the time period to which the current date and time belong is selected. The time period when the recorded data was recorded is included in the recorded history. This step is the step of selecting recorded history based on the time period when the recorded data was recorded in the recorded history. When the processing of step S1102 is completed, the control unit 30 ends the subroutine.

[0168] like Figure 17 As shown, the computer 40 of the control unit 30 executes a computationally intensive subroutine. The control unit 30 directs the computing unit 37 to... Figure 16The subroutine shown predicts the number of people gathered near recording device 11 based on the selected recording history, and adds these values ​​together to calculate the density near recording device 11. This subroutine is the step of calculating density based on the selected recording history.

[0169] In step S1201, the control unit 30 refers to a third recording time for each selected recording history. The third recording time is included in the recording history. When the processing of step S1201 ends, the control unit 30 proceeds to the processing of step S1202.

[0170] In step S1202, the control unit 30 causes the calculation unit 37 to calculate the number of people gathered near the recording device 11 based on the number table based on the third recording time for each recording history. Figure 18 The table shown is an example of a headcount table based on the third recording time. When the processing of step S1202 ends, the control unit 30 transfers to the processing of step S1203.

[0171] In step S1203, the control unit 30 sums up the number of people gathered near the recording device 11 in each recording history. The value obtained by summing these numbers is the density near the recording device 11, which is an indicator of the magnitude of the number of people gathered near the recording device 11. That is, the control unit 30 calculates the density near the recording device 11 based on the third recording time in the recording history whose time period coincides with the current date and time. Alternatively, the control unit 30 can also calculate the density near the recording device 11 within a specified time period based on the third recording time in the recording history whose time period coincides with a specified time period.

[0172] like Figure 18 As shown, the number of people gathered near the recording device 11 in the recorded history is calculated based on the third recording time. Furthermore, Figure 18 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Furthermore, the time divisions can be set appropriately. Additionally, a formula for calculating density can be used by substituting the third recorded time.

[0173] Since the longer the third recording time, the longer the time it takes to gather the recorded data at the recording device 11, it is best to set the value to be larger if the third recording time is longer.

[0174] like Figure 19As shown, the density near the recording device 11 can also be calculated based on the number of records in the selected recording history without using the third recording time. That is, the control unit 30 can also calculate the density based on the number of records in the recording history whose time period coincides with the current time period. Furthermore, the control unit 30 can also calculate the density near the recording device 11 within a specified time period based on the number of records in the recording history whose time period coincides with a specified time period. In addition, Figure 19 The values ​​shown in the table are examples, and the values ​​can be set appropriately. Additionally, the density near the recording device 11 can be calculated based on the number of users in the selected recording history.

[0175] The control unit 30 can also calculate the density near the recording device 11 within a specified time period. Furthermore, the control unit 30 can calculate the density near the recording device 11 for each time period. For example, a day can be divided into 24 time periods, and the density near the recording device 11 can be calculated for each of the 24 time periods. Moreover, the control unit 30 can also make the density near the recording device 11 for each time period a state that can be referenced by the user.

[0176] The role of the implementation method

[0177] The function of this embodiment will be explained.

[0178] The control unit 30 instructs the calculation unit 37 to calculate the density based on the recorded history. First, the control unit 30 selects from the recorded history of the user whose density will be notified, excluding recorded history outside the current time period. This improves the accuracy of the density calculation.

[0179] Next, the control unit 30 calculates the density for each saved history based on the third recording time. Therefore, when the time required to record the data is long, the density value can be increased. That is, when the frequency of data being gathered at the recording device 11 for recording is high, the density value can be increased.

[0180] When a user wants to send recorded data from the terminal 91, the control unit 30 notifies the terminal 91 of the current density. Therefore, the user can know the density near the recording device 11. The control unit 30 calculates the density for each time period and notifies the terminal 91 of these densities. This avoids using the recording device 11 during periods of high density.

[0181] Effects of the implementation method

[0182] The effects of this implementation method will be explained.

[0183] (14) When the density near the recording device 11 is set as the index representing the magnitude of the number of people predicted to be gathered near the recording device 11, the control unit 30 calculates the density based on the recording history stored in the storage unit 36. Furthermore, the control unit 30 makes this density a state that can be referenced by the user. Since the user can determine whether to go to the recording device 11 by referring to the density near the recording device 11, the frequency of contact or approach to people gathered near the recording device 11 can be reduced.

[0184] (15) The control unit 30 calculates the density for each time period when the recorded data in the recording history is recorded. Since the user can adjust the time period when going to the recording device 11 by referring to the density near the recording device 11 in each time period, the frequency of contact or approach to people gathered near the recording device 11 can be reduced.

[0185] (16) The control unit 30 calculates the density within the specified time period based on the third recording time in the recording history that coincides with the time period when the recorded data is recorded. Therefore, the user can avoid using the recording device 11 during periods when it is used for recording.

[0186] (17) The control unit 30 calculates the density within a specified time period based on the number of records in the recording history that coincide with the time period when the recorded data is recorded. Therefore, the user can avoid using the recording device 11 during time periods when it is used most frequently.

[0187] Example of a change in implementation method

[0188] This embodiment can be modified and implemented as follows. This embodiment and the following modifications can be combined and implemented within the scope of technical inconsistency.

[0189] The recording method of the recording device 11 to the medium M is not limited to inkjet printing. The recording device 11 may also be an electrophotographic or thermal transfer recording device, for example.

[0190] The recording device 11 may also include a detection unit that detects when the media receiving section 16 is extracted. Furthermore, the control unit 30 can calculate the density near the recording device 11 based on the detection results of the detection unit.

[0191] The recording device 11 may also be equipped with a human detection sensor to detect whether there are people near the recording device 11. Furthermore, the control unit 30 can calculate the density near the recording device 11 based on the output results of the human detection sensor.

[0192] The recording device 11 can also calculate the density near the recording device 11 based on the authentication status of the authentication unit 15a. For example, when a user is authenticated by the authentication unit 15a, the control unit 30 may determine that the user is currently using the recording device 11.

[0193] The distance from terminal 91 to recording device 11 can also be registered in recording device 11. Control unit 30 can also estimate the frequency of users of terminal 91 arriving near recording device 11 and notify users of the frequency.

[0194] Sometimes, media M from other users may be discharged onto the discharge tray that already contains media M from one user. When the detection units 17a, 57a, and 67a are sensors that detect the presence or absence of media M, in this case, the detection units 17a, 57a, and 67a do not distinguish which user's media M remains. Therefore, the elapsed time after the last discharge of media M onto the discharge tray can also be defined as the second elapsed time.

[0195] When a user sends multiple recording data to the recording device 11, the control unit 30 may calculate the number of people as low as possible when calculating the number of people based on information related to the user's second and subsequent recording data.

[0196] The control unit 30 can also calculate the density over several days based on the daily recording history. Furthermore, the control unit 30 can calculate the average of these densities. Moreover, the control unit 30 can use this average as the density near the recording device 11.

[0197] In the second embodiment, the time period is not limited to one hour; it can also be 30 minutes or 10 minutes. Additionally, the time unit can be two hours.

[0198] Users can also refer to the density based on the voice guidance of the terminal 91.

[0221] (K) Alternatively, the recording device may have a second prediction unit that predicts a second recording time, which is the time required from the start of recording in the recording unit until the end of the recording, and information related to the recorded data includes the second recording time.

[0222] According to this configuration, the frequency of contact or proximity to people who come to collect the media that will be discharged through the recording device can be reduced.

[0228] Based on this configuration, users can avoid using the recording device during periods when it is used for long periods of recording.

[0229] (O) In the above-described recording device, the control unit may calculate the density in the specified time period based on the number of records in the recording history that coincide with the specified time period.

[0231] (P) In the above-described recording device, the control unit may divide the vicinity of the recording device into multiple regions and calculate the density for each region.

[0232] Based on this configuration, the use of recording devices in densely populated areas can be avoided.

[0233] (Q) Alternatively, the recording device described above may include multiple discharge trays, and the control unit may calculate the density for each region where each discharge tray is configured, and select the discharge tray in the region with the lowest density as the discharge destination to discharge the medium.
