In the present embodiment, for example, the control unit 90 acquires a feeding counter value N based on the number of sheets S transported by the feeding unit 73 and life information LJ regarding the lifespan of the feeding unit 73 from the memory 92. do. The lifespan information LJ includes a first threshold value Nn and a second threshold value Ne. The first threshold value Nn and the second threshold value Ne are the number of sheets S transported by the feeding section 73, which is a guideline for replacing the feeding section 73. The second threshold Ne is a value larger than the first threshold Nn.

In step S01 of the flowchart shown in FIG. 10, the control unit 90 checks whether the paper S has been conveyed by the feeding unit 73. If the paper S is transported by the feeding section 73, the answer to step S01 becomes YES, and the control section 90 moves the process to step S12. If the sheet S is not transported by the feeding section 73, the answer to step S01 is NO, and the control section 90 ends the process. Note that whether or not the paper S has been transported by the feeding section 73 depends on the detection result of a paper detection sensor (not shown) provided in the transport path 17 at a position downstream of the feeding roller pair 21 in the transport direction. For example, when the feeding unit 73 is driven and the paper detection sensor detects passage of the paper S, the control unit 90 determines that the paper S has been conveyed. Further, for example, if the feeding unit 73 is driven and the paper detection sensor does not detect passage of the paper S, it is determined that the paper S has not been conveyed. In this case, the control unit 90 determines that the paper S has been misfed.

In step S02, the control unit 90 performs counter processing for the feeding counter value N. As a result, N=N+1. The control unit 90 stores the feeding counter value N that has been subjected to the counter processing in the memory 92 . After performing the process in step S02, the control unit 90 moves the process to step S03.

In step S03, the control unit 90 checks whether the feeding counter value N is greater than or equal to the first threshold value Nn. If the feeding counter value N is greater than or equal to the first threshold value Nn, step S03 becomes YES, and the control unit 90 moves the process to step S04. If the feeding counter value N is smaller than the first threshold value Nn, the answer to step S03 is NO, and the control unit 90 ends the process.

In step S04, the control unit 90 checks whether the feeding counter value N is greater than or equal to the second threshold Ne. If the feeding counter value N is greater than or equal to the second threshold Ne, step S04 becomes YES, and the control unit 90 moves the process to step S05. If the feeding counter value N is smaller than the second threshold Ne, the answer to step S04 is NO, and the control unit 90 moves the process to step S06.

In step S05, the control unit 90 determines that the usage state of the feeding unit 73 is a feeding unit end state in which the feeding unit 73 needs to be replaced. After performing the process of step S05, the control unit 90 ends the process for determining the usage state of the feeding unit 73.

In step S06, the control unit 90 determines that the usage state of the feeding unit 73 is a feeding unit near-end state in which replacement of the feeding unit 73 is desirable. After performing the process of step S06, the control unit 90 ends the process of determining the usage state of the feeding unit 73.

Next, the flowchart shown in FIG. 11 will be referred to regarding the flow of processing performed when the control unit 90 determines that the usage state of the feeding unit 73 is in the feeding unit near-end state in step S06 of the flowchart shown in FIG. I will explain. In the present embodiment, the flow of processing performed when the control unit 90 determines that the usage state of the feeding unit 73 is in the feeding unit near-end state corresponds to a method of controlling the feeding device.

In step S06 of the flowchart shown in FIG. 10, when it is determined that the usage state of the feeding section 73 is in the feeding section near-end state, in step S11 of the flowchart shown in FIG. Notify that this is the case. Specifically, the control unit 90 notifies the user by blinking Bn of the light emitting units 5a, 5b, and 5c.

In the blinking Bn of the light emitting units 5a, 5b, 5c in this embodiment, the control unit 90 alternately causes the light emitting units 5a, 5c to blink one by one among the light emitting units 5a, 5b, 5c at one second intervals. After performing the process in step S11, the control unit 90 moves the process to step S12.

In step S12, the control unit 90 displays a message prompting replacement of the feeding unit 73. For example, the control unit 90 causes the display unit 6 to display a setting screen SC as shown in FIG. In this case, in consideration of the case where the user does not wish to replace the feeding section 73 at this timing, in addition to displaying a prompt to replace the feeding section 73 on the setting screen SC, the feeding section 73 may be replaced at this timing. A message asking whether or not to exchange 73 is displayed. The setting screen SC is an example of a display.

In this embodiment, the display section 6 has a touch panel function, and displays radio button sections RB shown in FIG. 13 and FIGS. 14 to 17, which will be described later. Further, when the control section 90 is connected to the external device 201, the setting screen SC and radio button section RB shown in FIGS. 13 to 17 may be displayed on the display section 206 of the external device 201. After performing the process in step S12, the control unit 90 moves the process to step S13.

In step S13, the control unit 90 checks whether there is an input by the user to replace the feeding unit 73. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. It is determined that the instruction to replace the sending section 73 has been received. In this case, step S13 becomes YES, and the control unit 90 moves the process to step S16. If the user selects <No> in the radio button section RB shown in FIG. 13, the answer to step S13 is NO, and the control section 90 ends the process.

In step S16, the control unit 90 displays a display prompting a process to remove the paper S from the paper feed tray 60. For example, the control unit 90 causes the display unit 6 to display a setting screen SC as shown in FIG. In this case, on the setting screen SC, in addition to displaying a message asking the user to confirm that there is no paper S in the paper feed tray 60, it is also confirmed that there is no paper S in the paper feed tray 60 due to the user's processing. Display to the effect that Thereby, when there is paper S in the paper feed tray 60, the user is prompted to perform a process to remove the paper S from the paper feed tray 60. After performing the process in step S16, the control unit 90 moves the process to step S17.

In step S17, the control unit 90 checks whether there is an input by the user indicating that the process has been completed. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. 14, the control section 90 displays a message indicating that the user has completed the process of removing the paper S from the paper feed tray 60 from the radio button section RB. is input, and it is determined that there is no paper S in the paper feed tray 60. In this case, step S17 becomes YES, and the control unit 90 moves the process to step S18. If the user does not select <Yes> in the radio button section RB shown in FIG. 14, the control section 90 moves the process to step S16 and continues the process of step S16.

In step S18, the control section 90 moves the feeding section 73 to the exchange position. For example, as shown in FIG. 9, when the feeding section 73 is at the home position, the control section 90 controls the feeding motor to move the feeding section 73 from the -X direction side to the +X direction. The rotating shaft 74 is rotated clockwise in the direction of the black arrow, and the feeding section 73 is moved to the replacement position shown in FIG. In other words, after receiving an instruction to replace the feeding unit 73 from the instruction receiving unit IP, the control unit 90 switches the position of the feeding unit 73 to the replacement position. After performing the process in step S18, the control unit 90 moves the process to step S19.

In step S19, the control unit 90 displays a message urging careful confirmation of the replacement operation. For example, the control unit 90 causes the display unit 6 to display a setting screen SC as shown in FIG. 15 so that the user confirms the replacement method and then replaces the feeding unit 73. After performing the process in step S19, the control unit 90 moves the process to step S20.

In step S20, the control unit 90 checks whether there is an input by the user indicating confirmation. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. 15, the control section 90 determines that there has been an input from the radio button section RB by the user to perform a careful replacement operation. . In this case, step S20 becomes YES, and the control unit 90 moves the process to step S21. If the user does not select <Yes> in the radio button section RB shown in FIG. 15, the control section 90 moves the process to step S19 and continues the process of step S19.

While the user confirms the careful replacement operation and replaces the feeding section 73 according to the procedure described above, the control section 90 displays a display to confirm whether the replacement of the feeding section 73 is completed in step S21. indicate. For example, the control unit 90 causes the display unit 6 to display a setting screen SC as shown in FIG. After performing the process in step S21, the control unit 90 moves the process to step S22.

In step S22, the control unit 90 checks whether there is an input indicating that the replacement of the feeding unit 73 has been completed. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. It is determined that the replacement of the sending section 73 has been completed. In this case, step S22 becomes YES, and the control unit 90 moves the process to step S23. If the user selects <No> in the radio button section RB shown in FIG. 16 or does not select any button, the control section 90 moves the process to step S21 and continues the process of step S21.

In step S23, the control section 90 moves the feeding section 73 to the home position. For example, assume that the user has finished replacing the feeding section 73 and the replaced feeding section 73 is at the replacement position as shown in FIG. In this case, the control unit 90 drives and controls the feeding motor to rotate the rotating shaft 74 in a clockwise direction when looking at the feeding unit 73 from the −X direction side to the +X direction, so that the replaced feed The sending section 73 is moved to the home position shown in FIG. After performing the process in step S23, the control unit 90 moves the process to step S24.

In step S24, the control unit 90 resets the feeding counter value N. As a result, N=0. The control unit 90 stores the feeding counter value N that has been subjected to the counter processing in the memory 92 . After performing the process in step S24, the control unit 90 moves the process to step S25.

In step S25, the control section 90 ends the notification of the near-end state of the feeding section 73 by blinking Bn of the light emitting sections 5a, 5b, and 5c. As a result, the light emitting parts 5a, 5b, and 5c are turned off. After performing the process of step S25, the control unit 90 ends the process performed when the usage state of the feeding unit 73 is determined to be in the feeding unit near-end state.

Next, the flowchart shown in FIG. 12 is referred to regarding the flow of processing performed when the control unit 90 determines that the usage state of the feeding unit 73 is the feeding unit end state in step S05 of the flowchart shown in FIG. I will explain. In this embodiment, the flow of processing performed when the control unit 90 determines that the usage state of the feeding unit 73 is the feeding unit end state corresponds to a method of controlling the feeding device. Note that the processing from step S12 and step S16 to step S24 in the flowchart shown in FIG. 12 is the same as the processing from step S12 and step S16 to step S24 in the flowchart shown in FIG. 11, so a detailed explanation will be omitted. .

In step S05 of the flowchart shown in FIG. 10, when it is determined that the usage state of the feeding section 73 is in the feeding section end state, in step S26 of the flowchart shown in FIG. Notify that this is the case. Specifically, the control unit 90 notifies the user by blinking Be of the light emitting units 5a, 5b, and 5c.

In the blinking Be of the light emitting sections 5a, 5b, and 5c in this embodiment, the control section 90 causes two of the light emitting sections 5a, 5b, and 5c to blink simultaneously at one-second intervals. After performing the process in step S26, the control unit 90 moves the process to step S12.

In step S12, the control unit 90 performs the process of step S12, and then moves the process to step S13.

In step S13, the control unit 90 checks whether there is an input by the user to replace the feeding unit 73. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. It is determined that the instruction to replace the sending section 73 has been received. In this case, step S13 becomes YES, and the control unit 90 moves the process to step S16. If the user selects <No> in the radio button section RB shown in FIG. 13, the answer to step S13 becomes NO, and the control section 90 moves the process to step S14.

In step S14, the control unit 90 displays a message prompting replacement of the feeding unit 73. In other words, when the feeding section 73 is in the end state, that is, when the feeding counter value N is equal to or greater than the second threshold Ne, the control section 90 displays a message prompting to replace the feeding section 73 multiple times. At this time, for example, the control section 90 causes the display section 6 to display a setting screen SC as shown in FIG. In this case, in consideration of the case where the user does not wish to replace the feeding section 73 at this timing, in addition to displaying a prompt to replace the feeding section 73 on the setting screen SC, the feeding section 73 may be replaced at this timing. A message asking whether or not to exchange 73 is displayed. After performing the process in step S14, the control unit 90 moves the process to step S15.

In step S15, the control unit 90 checks whether there is an input by the user to replace the feeding unit 73. Specifically, when the user selects <Yes> in the radio button section RB shown in FIG. It is determined that the instruction to replace the sending section 73 has been received. In this case, step S15 becomes YES, and the control unit 90 moves the process to step S16. If the user selects <No> in the radio button section RB shown in FIG. 17, the answer to step S15 is NO, and the control section 90 ends the process.

In steps S16 to S24, the control unit 90 performs the same processing as that in steps S16 to S24 in the flowchart shown in FIG. After performing the process in step S24, the control unit 90 moves the process to step S27.

In step S27, the control section 90 ends the notification of the end state of the feeding section 73 by blinking Be of the light emitting sections 5a, 5b, and 5c. As a result, the light emitting parts 5a, 5b, and 5c are turned off. After performing the process of step S27, the control unit 90 ends the process performed when the usage state of the feeding unit 73 is determined to be the feeding unit end state.

Next, the flowchart shown in FIG. 11 will be referred to regarding the flow of processing performed when the recording apparatus 1 does not include the display unit 6 and the control unit 90 determines that the usage state of the feeding unit 73 is in the feeding unit near-end state. I will explain. Note that in an embodiment in which the recording device 1 does not include the display unit 6, the setting screen SC cannot be displayed, so the control unit 90 executes the processing of steps S12, S16, S17, S19, S20, and S21 in the flowchart shown in FIG. Not performed.

In step S11, the control unit 90 notifies that the feeding unit 73 is in a near-end state. Specifically, the control unit 90 notifies the user by blinking Bn of the light emitting units 5a, 5b, and 5c. In the blinking Bn of the light emitting units 5a, 5b, 5c in this embodiment, the control unit 90 alternately causes the light emitting units 5a, 5c to blink one by one among the light emitting units 5a, 5b, 5c at one second intervals. After performing the process in step S11, the control unit 90 moves the process to step S13.

In step S13, the control unit 90 checks whether there is an input by the user to replace the feeding unit 73. When the user replaces the feeding unit 73 after confirming the notification of the near-end state of the feeding unit by the blinking Bn of the light emitting units 5a, 5b, and 5c, in this embodiment, the user presses the operation buttons 4a and 4b of the operation panel 4. , 4c to input that the feeding section 73 is to be replaced.

Specifically, the user presses the two operation buttons 4b and 4c simultaneously for 5 seconds or more. Thereby, the control unit 90 determines that there is an input from the user to replace the feeding unit 73 and that the instruction to replace the feeding unit 73 has been received. In other words, the control unit 90 determines that a replacement instruction for the feeding unit 73 is issued when at least two of the operation buttons 4a, 4b, and 4c are pressed at the same time. In this case, step S13 becomes YES, and the control unit 90 moves the process to step S18. If there is no input using the operation buttons 4b and 4c described above even after a predetermined period of time has elapsed since the process in step S11, the result in step S13 is NO, and the control unit 90 ends the process.

In step S18, the control section 90 moves the feeding section 73 to the exchange position as described above. After performing the process in step S18, the control unit 90 moves the process to step S22. When the feeding section 73 is moved to the replacement position, the user replaces the feeding section 73 using the procedure described above.

In step S22, the control unit 90 checks whether there is an input indicating that the replacement of the feeding unit 73 has been completed. When the replacement of the feeding section 73 is completed, in this embodiment, the user uses the operation buttons 4a, 4b, and 4c of the operation panel 4 to input that the replacement of the feeding section 73 has been completed.

Specifically, the user presses the two operation buttons 4a and 4c simultaneously for 5 seconds or more. As a result, the control unit 90 receives an input from the user indicating that the replacement of the feeding unit 73 has been completed, and determines that the replacement of the feeding unit 73 has been completed. In other words, the control unit 90 determines that the replacement of the feeding unit 73 is completed when at least two of the operation buttons 4a, 4b, and 4c are pressed at the same time. In this case, step S22 becomes YES, and the control unit 90 moves the process to step S23. If there is no input using the above-mentioned operation buttons 4a, 4c, the control unit 90 continues the process of step S22.

The control unit 90 performs the processes of steps S23, S24, and S25 in the same way as in the case where the recording device 1 includes the display unit 6, and performs the processes performed when the usage state of the feeding unit 73 is determined to be in the feeding unit near-end state. end.

Regarding the flow of processing performed when the recording device 1 does not include the display section 6 and the control section 90 determines that the usage state of the feeding section 73 is the feeding section end state, the recording device 1 cannot display the setting screen SC. Therefore, the control unit 90 does not perform steps S12, S14, S15, S16, S17, S19, S20, and S21 in the flowchart shown in FIG.

Therefore, the flow of processing performed when the recording device 1 does not include the display section 6 and the control section 90 determines that the usage state of the feeding section 73 is the feeding section end state is that the recording device 1 does not include the display section 6. The processing in steps S11 and S25 in the flow of processing performed when the control unit 90 determines that the usage state of the feeding unit 73 is in the feeding unit near-end state is the processing in steps S26 and S27 in the flowchart shown in FIG. Since they are the same except for , the explanation will be omitted.

As described above, according to the feeding device, the recording device, and the method of controlling the feeding device according to the first embodiment, the following effects can be obtained.

The feeding device 2 includes a housing 10, a paper feeding tray 60 on which the paper S is placed, and a feeding section 73 that transports the paper S from the paper feeding tray 60. A feeding roller part 73a that is removable from the rotating shaft 74, and a fitted part 73b that is fitted into a fitting part 74b provided on the rotating shaft 74 that rotates the feeding roller part 73a. 73 and a control section 90 that controls the rotation of the feeding section 73. The control unit 90 is provided in the housing 10 so as to be rotatably movable to a possible replacement position, and when the feeding unit 73 is replaced, the control unit 90 switches the position of the feeding unit 73 to the replacement position. According to this, since the control section 90 rotates the feeding section 73 to the replacement position, the feeding section 73 can be easily replaced. Therefore, usability can be provided to users.

The housing 10 has an opening 10h that exposes the feeding section 73 to the outside, and the mounting surface 61 on which the paper S is mounted in the paper feed tray 60 is vertically aligned along the transport direction in which the paper S is transported. When the feeding section 73 is at the replacement position, the removal direction T in which the feeding section 73 is removed from the rotating shaft 74 is toward the opening 10h, and the feeding section 73 is at the home position. In this case, the removal direction T is toward the inner surface 10w of the housing 10. According to this, when the feeding section 73 is in the replacement position, the user can easily replace the feeding section 73 through the opening 10h. Furthermore, when the feeding section 73 is at the home position, it is possible to prevent the user from accidentally removing the feeding section 73 at the home position.

The recording device 1 includes an instruction receiving unit IP that receives instructions from a user, and after receiving an instruction to replace the feeding unit 73 from the instruction receiving unit IP, the control unit 90 changes the position of the feeding unit 73 to the replacement position. Switch. According to this, usability for the user is improved.

The instruction receiving unit IP includes a display unit 6, and after receiving the instruction to replace the feeding unit 73 from the instruction receiving unit IP, the control unit 90 prompts to confirm whether the paper S is placed on the paper feeding tray 60. The display is displayed on the display unit 6. According to this, it is possible to prevent the paper S placed on the paper feed tray 60 from being transported by the operation of switching the position of the feeding section 73 to the exchange position.

The instruction reception unit IP includes a plurality of operation buttons 4a, 4b, and 4c, and the control unit 90 controls the feeding unit 73 when at least two of the operation buttons 4a, 4b, and 4c are pressed. It is determined that this is a replacement instruction. According to this, for example, compared to pressing one operation button, it is possible to suppress moving the feeding section 73 to the exchange position due to pressing the operation button by mistake. Moreover, according to this, it is difficult to press the radio button RB by mistake compared to the case where the radio button RB displayed on the display section 6 is pressed.

The control unit 90 determines that the replacement of the feeding unit 73 is completed when at least two of the plurality of operation buttons 4a, 4b, and 4c are pressed. According to this, for example, compared to pressing a single operation button, accidentally pressing the operation button while replacing the feeding section 73 causes the feeding section 73 to be moved from the replacement position. can be suppressed. Moreover, according to this, it is difficult to press the radio button RB by mistake compared to the case where the radio button RB displayed on the display section 6 is pressed.

When the feeding section 73 is replaced and the feeding section 73 is attached to the rotating shaft 74, the control section 90 rotates the feeding section 73 to the home position. If the feeding unit 73 is moved to the home position after the paper S is placed on the paper feed tray 60, the amount of conveyance of the paper S will differ by the amount of rotation of the feeding unit 73 from the exchange position to the home position. . In contrast, the control section 90 returns the feeding section 73 attached to the rotary shaft 74 to the home position before the sheet S is placed on the sheet feeding tray 60. It is possible to appropriately convey the paper S that has been moved.

The recording device 1 includes an opening/closing member 11 that has its rotation center on the −Y direction side in the Y-axis direction of the housing 10 and is provided to be able to open and close the upper part of the housing 10 . The instruction reception unit IP is provided at the +X direction end of the housing 10 in the X-axis direction that intersects with the Y-axis direction of the housing 10, and It is provided at a position that is on the direction side and does not overlap with the feeding section 73. According to this, it is possible to suppress malfunctions such as the user accidentally touching the instruction receiving part IP during the replacement operation of the feeding part 73 and the feeding part 73 moving from the replacement position.

The feeding section 73 includes an operating section 73f that is movable in the X-axis direction, and the feeding section 73 can be attached to and detached from the rotating shaft 74 by moving the operating section 73f. According to this, the feeding section 73 can be easily replaced.

The control unit 90 acquires a feeding counter value N based on the number of sheets S transported by the feeding unit 73 and life information LJ regarding the life of the feeding unit 73, and calculates the feeding counter value N and the life information. Based on LJ, the display section 6 displays a message prompting the replacement of the feeding section 73. According to this, the control unit 90 determines the timing for replacing the feeding unit 73 and prompts the user to replace it, so that the user can be prompted to replace the feeding unit 73 at an appropriate timing.

The life information LJ includes a first threshold value Nn and a second threshold value Ne that is larger than the first threshold value Nn, and when the feeding counter value N is greater than or equal to the first threshold value Nn and smaller than the second threshold value Ne , the control section 90 displays a display prompting the replacement of the feeding section 73. According to this, the control unit 90 determines the timing for replacing the feeding unit 73 and prompts the user to replace it, so that the user can be prompted to replace the feeding unit 73 at an appropriate timing.

When the feeding counter value N is equal to or greater than the second threshold Ne, the control unit 90 causes a display prompting to replace the feeding unit 73 to be displayed multiple times. According to this, it is possible to strongly urge the user to replace the feeding section 73.

The recording device 1 includes a feeding device 2 and a recording section 30 that records on the sheet S that is being transported. According to this, the recording unit 30 can perform recording on the paper S that is appropriately conveyed by the feeding device 2.

The method of controlling the feeding device includes a paper feeding tray 60 on which the paper S is placed, and a feeding unit 73 that transports the paper S from the paper feeding tray 60. A feeding portion 73 that is removable from the rotating shaft 74 and includes a roller portion 73a and a fitted portion 73b that is fitted into a fitting portion 74b provided on a rotating shaft 74 that rotates the feeding roller portion 73a. , when the feeding unit 73 is replaced, the feeding unit 73 is replaced so that it can be removed from the rotating shaft 74 from the home position where the paper S placed on the paper feeding tray 60 is transported. The position of the feeding section 73 is switched to the position shown in FIG. According to this, the feeding section 73 is moved to the replacement position under the control of the feeding device, so that the feeding section 73 can be easily replaced. Therefore, usability can be provided to users.

The feeding device, the recording device, and the control method for the feeding device according to the embodiments of the present disclosure are basically configured as described above, but may be implemented within the scope of the gist of the present disclosure. Of course, it is also possible to partially change or omit the configuration within the system. Further, the above embodiment and other embodiments described below can be implemented in combination with each other within a technically consistent range. Other embodiments will be described below.

In the above embodiment, the outer shape of the shaft 74a of the rotating shaft 74 that constitutes the feeding drive roller 71 does not have to be circular when viewed from the direction along the X-axis. For example, the outer shape of the shaft 74a may be the same shape as the fitting portion 74b when viewed from the direction along the X-axis. In this case, the rotating shaft 74 does not need to include the fitting portion 74b. Furthermore, in this case, it can be said that the fitted portion 73b of the feeding section 73 is fitted into the shaft 74a of the rotating shaft 74.

In the above embodiment, the home position of the feeding section 73 is a position where the removal direction T faces the inner surface 10w of the housing 10 and the attachment/detachment opening 73e of the feeding section 73 faces the placement surface 61 of the paper feeding tray 60. There may be.

In the embodiment described above, when the feeding section 73 is at the home position, the removal direction T does not need to be directed toward the inner surface 10w of the housing 10, as long as the removal direction T is not directed toward the opening 10h. For example, when the feeding section 73 is at the home position, the removal direction T may be toward the top or bottom surface of the housing 10, or may be toward the mounting surface 61 of the paper feed tray 60.
