Description

Technical Field

[0001] The present invention relates to a recording device such as a printer. Background Art

[0002] For example, as described in Patent Document 1, there is a recording device that prints by ejecting liquid from a recording unit. The recording device includes a driving roller, a driven roller, a second rotating shaft as an example of a rotating shaft, and a loading detection device. The loading detection device includes a starting member, a transmission member, a first contact member, and a detection auxiliary member.

[0003] In the recording device, a stacker as an example of a medium storage device is detachably mounted. When the stacker is not mounted, the driven roller is located at a position separated from the driving roller.

[0004] When the medium is discharged to the stacker, the second rotating shaft is rotated to move the driven roller to a position where the medium can be sandwiched between the driven roller and the stacking detection device. The detection auxiliary component is moved to the detection position in conjunction with the movement of the driven roller, thereby achieving a state in which the amount of the medium stacked on the stacker can be detected.

[0005] In Patent Document 1, when the first contact member rotates around the second rotation axis, the displacement of the medium loading amount is transmitted via the actuating member, the transmitting member, and the auxiliary detection member. Therefore, the recording device has a large number of components and a complicated structure.

[0014] Implementation

[0015] Hereinafter, one embodiment of a recording device and a recording system including the recording device will be described with reference to the drawings. The recording device is an inkjet printer that performs recording by ejecting ink, which is an example of liquid, onto a medium such as paper, cloth, or vinyl.

[0016] In the drawings, the recording system 11 is placed on a horizontal plane, and the Z axis represents the direction of gravity, and the X axis and the Y axis represent the direction along the horizontal plane. The X axis, the Y axis, and the Z axis are orthogonal to each other. In the following description, the direction parallel to the X axis is also referred to as the width direction X.

[0017] Recording system

[0018] like Figure 1 As shown, the recording system 11 includes a medium storage device 12 and a recording device 13 .

[0019] Media storage device

[0020] The medium storage device 12 is detachably mounted on the recording device 13. The medium storage device 12 mounted on the recording device 13 can store the medium 15 discharged from the recording device 13. The medium storage device 12 may include a discharge tray 16, a pressing portion 17, and an arm 18.

[0021] The discharge tray 16 receives the medium 15 discharged from the recording device 13. The recorded medium 15 is stacked on the discharge tray 16.

[0022] The pressing portion 17 presses the medium 15 stacked on the discharge tray 16 .

[0023] The arm 18 may be inserted into the recording device 13 when the medium storage device 12 is mounted on the recording device 13, thereby positioning the medium storage device 12 relative to the recording device 13. The arm 18 may also abut against the recording device 13 when the medium storage device 12 is mounted on the recording device 13.

[0024] Recording device

[0025] The recording device 13 may include a housing 20 , a control unit 21 , an unwinding unit 22 , a conveying unit 23 , a recording unit 24 , a supporting unit 25 , a cutting unit 26 , and a discharge mechanism 27 .

[0026] The housing 20 accommodates various components of the recording device 13. The housing 20 may include an outlet 29 for discharging the recorded medium 15. The medium storage device 12 may be mounted on the outlet 29.

[0027] The control unit 21 controls the driving of each mechanism in the recording device 13 in a centralized manner, thereby controlling various operations performed in the recording device 13 .

[0028] The control unit 21 can be configured as a circuit including α, β or γ, wherein α: one or more processors that perform various processes according to a computer program; β: one or more dedicated hardware circuits that perform at least a part of the various processes; γ: a combination thereof. The hardware circuit is, for example, an integrated circuit for a specific purpose. The processor includes a CPU, and a memory such as a RAM and a ROM, and the memory stores program codes or instructions configured to cause the CPU to perform the process. The memory, i.e., a computer-readable medium, includes all readable media that can be accessed by a general-purpose or dedicated computer.

[0029] The unwinding unit 22 may also include more than one unwinding shaft 31. The unwinding shaft 31 supports the roll body 32 in a rotatable manner. The roll body 32 is a component that rolls the long medium 15 into a cylindrical shape. The unwinding shaft 31 unwinds the medium 15 by rotating the roll body 32. When the unwinding unit 22 includes a plurality of unwinding shafts 31, the unwinding unit 22 rotates one unwinding shaft 31 that supports the unwound medium 15.

[0030] The conveying unit 23 is along Figure 1 The medium 15 is transported along the transport path 34 indicated by the double-dashed line in FIG. The transport unit 23 may also transport the medium 15 by sandwiching the medium 15 with a pair of rotating rollers. The transport unit 23 transports the medium 15 in the transport direction Dc. The transport direction Dc is a direction along the transport path 34.

[0031] The recording unit 24 performs recording on the medium 15. The recording unit 24 may perform recording on the medium 15 by ejecting liquid from a nozzle (not shown).

[0032] The support unit 25 supports the portion of the long medium 15 to be recorded by the recording unit 24 .

[0033] The cutting unit 26 is provided downstream of the recording unit 24 in the conveying direction Dc. The cutting unit 26 can cut the recorded medium 15 across the width direction X. The cutting unit 26 can also cut the medium 15 by moving the pair of cutting blades 36 in the width direction X.

[0034] Discharge mechanism

[0035] like Figure 1 As shown in FIG. 2 , the discharge mechanism 27 may also include a discharge portion 38 and a rotation shaft 39. Figure 2 As shown, the discharge unit 38 may include a discharge roller 41 , a driven roller 42 , and a holding unit 43 .

[0036] The discharge roller 41 is driven to rotate by a motor (not shown).

[0037] The driven roller 42 may rotate in a driven manner relative to the discharge roller 41. The driven roller 42 may be a toothed roller. If the roller in contact with the recording surface of the medium 15 is a toothed roller, it is possible to suppress a decrease in recording quality.

[0038] The holding portion 43 rotatably holds the driven roller 42. The holding portion 43 is fixed to the rotating shaft 39 so as to rotate integrally with the rotating shaft 39. The rotation refers to rotation around the shaft, and the rotatable angle is less than 360 degrees.

[0039] The rotating shaft 39 can rotate in a first rotating direction R1 and a second rotating direction R2. The first rotating direction R1 is a direction opposite to the second rotating direction R2. The rotating shaft 39 rotates the discharge portion 38 to Figure 1 The clamping position P1 shown, and Figure 2 Specifically, the rotating shaft 39 rotates the holding portion 43 to move the driven roller 42. When the rotating shaft 39 rotates in the first rotation direction R1 from the state where the discharge portion 38 is located at the non-clamping position P2, the holding portion 43 and the driven roller 42 move to the clamping position P1. When the rotating shaft 39 rotates in the second rotation direction R2 from the state where the discharge portion 38 is located at the clamping position P1, the holding portion 43 and the driven roller 42 move to the non-clamping position P2.

[0040] The nip position P1 is a position where the driven roller 42 is close to the discharge roller 41. The nip position P1 is a position where the medium 15 can be nipped.

[0041] The non-gripping position P2 is a position where the driven roller 42 is separated from the discharge roller 41. The non-gripping position P2 is a position where the medium 15 cannot be gripped.

[0042] The discharge unit 38 nips and discharges the recorded medium 15 . The discharge unit 38 may discharge the medium 15 from the discharge port 29 by nipping the medium 15 between the discharge roller 41 and the driven roller 42 and rotating the discharge roller 41 .

[0043] The discharge unit 38 may be located at the clamping position P1 when the medium 15 is cut by the cutting unit 26. The discharge unit 38 may clamp the cut medium 15 and discharge it by the discharge roller 41 and the driven roller 42. The discharge unit 38 may be located at the non-clamping position P2 when the cutting unit 26 does not cut the medium 15. The discharge unit 38 may discharge the long medium 15 that has not been cut by the discharge roller 41.

[0044] like Figure 2 As shown, the discharge mechanism 27 may include a detection portion 45 , a mounting detection member 46 , a spring 47 , a contact member 48 , and a detection auxiliary member 49 .

[0045] The detection unit 45 is, for example, a photoelectric sensor having a light-emitting unit and a light-receiving unit. The detection unit 45 may also detect the displacement of the mounting detection component 46, the abutment component 48, and the detection auxiliary component 49. The detection unit 45 of this embodiment detects the displacement of each component by determining whether the optical axis 51 is blocked. In the following description, the state in which the optical axis 51 is blocked is also referred to as a detection state, and the state in which the optical axis 51 is not blocked is also referred to as a non-detection state.

[0046] like Figure 3 As shown, the installation detection component 46 may also include a first rod 53 and a first light shield 54. The installation detection component 46 is displaced along with the installation and removal of the medium storage device 12. The installation detection component 46 of this embodiment is configured to be rotatable around the first axis 55. The installation detection component 46 rotates in a manner linked to the installation and removal of the medium storage device 12.

[0047] like Figure 2 , Figure 3As shown, when the medium storage device 12 is not installed on the recording device 13, the installation detection component 46 is located at the non-installation position P3. When the installation detection component 46 is located at the non-installation position P3, the first light shielding device 54 shields the optical axis 51. That is, when the medium storage device 12 is not installed, the installation detection component 46 is at a position detected by the detection unit 45.

[0048] like Figure 4 As shown, when the medium storage device 12 is installed on the recording device 13, the arm 18 presses the first rod 53. The installation detection component 46 moves to the installation position P4 by rotating around the first axis 55. When the installation detection component 46 moves to the installation position P4, the first light shield 54 rotating around the first axis 55 leaves the detection unit 45. That is, when the medium storage device 12 is installed, the installation detection component 46 is in a position where it is not detected by the detection unit 45. For the recording device 13, when the discharge unit 38 is located at the non-clamping position P2, the detection unit 45 detects that the detection state based on the installation detection component 46 has changed to the non-detection state, thereby being able to detect that the medium storage device 12 has been installed.

[0049] The spring 47 presses the mounting detection member 46 located at the mounting position P4 toward the non-mounting position P3. Therefore, when the medium storage device 12 is removed from the recording device 13, the mounting detection member 46 returns to the non-mounting position P3.

[0050] The rotation shaft 39 has a protrusion 57 . The protrusion 57 engages with the contact member 48 .

[0051] The contact member 48 is provided with a swing limiting portion 58. The protrusion 57 may also be provided in the swing limiting portion 58. Although the contact member 48 can swing by contacting the medium 15 discharged from the discharge port 29, the swing limiting portion 58 is engaged with the protrusion 57, thereby limiting the range of the swing of the contact member 48. The swing limiting portion 58 may also include a first wall 59 and a second wall 60. The position of the protrusion 57 around the rotation axis 39 changes with the rotation of the rotation axis 39. The position of the protrusion 57 changes, so that the position where the protrusion 57 is engaged with the swing limiting portion 58 changes, and the swingable position of the contact member 48 changes.

[0052] The abutment member 48 swings around the rotation shaft 39. The abutment member 48 is not fixed to the rotation shaft 39. The abutment member 48 slides relative to the rotation shaft 39. The abutment member 48 is axially supported by the rotation shaft 39 at a position deviating from the center of gravity of the abutment member 48. Although the abutment member 48 intends to rotate in a manner that the portion in contact with the medium 15 descends, the rotation of the abutment member 48 is sometimes restricted due to the position of the protrusion 57. For example, the rotation of the abutment member 48 can be restricted in a manner that the first wall 59 of the swing limiting portion 58 contacts the protrusion 57 so that the portion in contact with the medium 15 does not descend. The abutment member 48 may also have an abutment surface 62. The abutment surface 62 abuts against the detection auxiliary member 49.

[0053] like Figure 3 As shown, the detection auxiliary component 49 may also have a second rod 64 and a second light shield 65. The detection auxiliary component 49 abuts against the abutment component 48. Specifically, the second rod 64 of the detection auxiliary component 49 abuts against the abutment surface 62. The so-called abutment is contact in an abutting manner. The detection auxiliary component 49 is displaced in a manner linked to the displacement of the abutment component 48. The detection auxiliary component 49 of this embodiment is configured to be able to rotate around the second axis 66. The detection auxiliary component 49 is rotated in a manner linked to the displacement of the abutment component 48.

[0054] The first shaft 55 and the second shaft 66 can rotate separately. The first shaft 55 and the second shaft 66 can also be set so that their respective axes are arranged in a straight line. The installation detection component 46 can also be supported on the same axis as the detection auxiliary component 49. The installation detection component 46 and the detection auxiliary component 49 can also be supported on an axis different from the rotation axis 39.

[0055] like Figure 4 As shown, when the discharge unit 38 is at the non-clamping position P2, the detection auxiliary member 49 may be at a position not detected by the detection unit 45. When the discharge unit 38 is at the clamping position P1, the detection auxiliary member 49 can move between a position detected by the detection unit 45 and a position not detected.

[0056] exist Figure 4 In the state shown, the contact member 48 is located at the initial position P5. The protrusion 57 presses the first wall 59, so that the contact member 48 is located at the initial position P5. The second rod 64 of the detection auxiliary member 49 abuts against the abutment surface 62. The second light shield 65 of the detection auxiliary member 49 is located above the detection portion 45. The second light shield 65 does not block the optical axis 51.

[0057] That is, if the medium storage device 12 is installed on the recording device 13 and the installation detection component 46 moves to the installation position P4, the detection unit 45 becomes a non-detection state in which the first shading device 54 and the second shading device 65 are not detected, and it is possible to detect that the medium storage device 12 has been installed. When it is detected that the medium storage device 12 is installed, the control unit 21 rotates the rotation shaft 39 in the first rotation direction R1. When the rotation shaft 39 rotates in the first rotation direction R1, the discharge mechanism 27 becomes Figure 5 Even if the rotating shaft 39 rotates in the first rotation direction R1, the installation detection member 46 remains at the installation position P4.

[0058] like Figure 5 As shown, when the rotating shaft 39 rotates in the first rotation direction R1, the holding portion 43 and the protrusion 57 rotate together with the rotating shaft 39. The holding portion 43 moves the driven roller 42 to the clamping position P1.

[0059] The swingable range of the abutment member 48 is from the position where the first wall 59 abuts against the protrusion 57 to the position where the second wall 60 abuts against the protrusion 57, with the rotation axis 39 as the center. Therefore, when the rotation axis 39 rotates and the position of the protrusion 57 changes, the position where the abutment member 48 can swing changes. When the rotation axis 39 rotates, the position of the discharge portion 38 changes. Therefore, when the discharge portion 38 is located at the clamping position P1 and when it is located at the non-clamping position P2, the position where the abutment member 48 can swing changes. That is, in the case of the rotation axis 39 rotating around the axis, the position where the first wall 59 or the second wall 60 implements rotation restriction with respect to the protrusion 57 changes. Therefore, the position of the angle at which the abutment member 48 is subject to rotation restriction around the rotation axis 39 changes.

[0060] When the discharge portion 38 changes from the state at the non-clamping position P2 to the state at the clamping position P1, when the protrusion 57 rotates and leaves the first wall 59, the top end 68 of the contact member 48 drops due to its own weight. The contact member 48 may also be moved to the lower limit position P6 and abut against a positioning portion (not shown) so that the rotation in the first rotation direction R1 is restricted. At this time, the angle at which the contact member 48 rotates may be smaller than the angle at which the rotation shaft 39 rotates. The protrusion 57 may also leave the first wall 59. The protrusion 57 may also leave the second wall 60.

[0061] The detection auxiliary component 49 moves along the abutment surface 62 of the rotating abutment component 48. The detection auxiliary component 49 rotates around the second axis 66, so that the second light shield 65 passes through the detection unit 45. When the abutment component 48 is located at the lower limit position P6, the second light shield 65 of the detection auxiliary component 49 is located below the detection unit 45. The second light shield 65 does not block the optical axis 51. Therefore, when the second light shield 65 passes through the detection unit 45, the detection unit 45 switches in the order of non-detection state, detection state, and non-detection state.

[0062] The second shade 65 and the first shade 54 can independently rotate about the second axis 66 or the first axis 55 and pass through the detection unit 45. Since the same detection unit 45 is used and rotates about the same axis, the second shade 65 and the first shade 54 can be easily adjusted.

[0063] The contact member 48 at the lower limit position P6 can contact the discharged medium 15. That is, the contact member 48 can be located at a position where the discharged medium 15 passes.

[0064] like Figure 6 As shown, the contact member 48 abutting the medium 15 rotates in the second rotation direction R2 and moves to the detection position P7. When the contact member 48 is located at the detection position P7, the second light shield 65 of the detection auxiliary member 49 shields the optical axis 51. The detection unit 45 enters the detection state.

[0065] The rotating shaft 39 may also be changed as the discharge section 38 clamps the medium 15. When the discharge section 38 is located at the clamping position P1, when the discharge roller 41 and the driven roller 42 clamp the medium 15, the driven roller 42 moves away from the discharge roller 41 by an amount corresponding to the thickness of the medium 15. Since the holding section 43 is pressed by the movement of the driven roller 42, the rotating shaft 39 that fixes the holding section 43 is also pressed. Therefore, the rotating shaft 39 may also be able to move in a direction away from the discharge roller 41 by an amount corresponding to the thickness of the medium 15. The contact surface 62 may also be formed so that when the discharge section 38 is rotated to the clamping position P1, the discharge section 38 moves along the direction in which the rotating shaft 39 moves along the clamping of the medium 15. That is, the contact surface 62 of the contact member 48 contacts the second rod 64 of the detection auxiliary member 49 in a sliding manner along the direction in which the rotating shaft 39 moves along the clamping of the medium 15. Since the detection auxiliary component 49 rotates on an axis different from the rotation axis 39 , even if the rotation axis 39 changes, the rotation of the detection auxiliary component 49 is not affected.

[0066] like Figure 5As shown, when the medium 15 passes through the discharge mechanism 27 and leaves the contact member 48, the contact member 48 returns to the lower limit position P6. Therefore, the detection unit 45 enters a non-detection state.

[0067] However, in the case where the medium 15 remains in the discharge section 38, in the case where the medium 15 discharged into the medium storage device 12 is deformed and contacts the abutment member 48, or in the case where the medium 15 exceeds the maximum amount and is loaded on the discharge tray 16, the medium 15 sometimes remains in contact with the abutment member 48. In other words, the detection unit 45 sometimes does not return to the non-detection state. When the discharge section 38 discharges the medium 15, if the detection unit 45 does not return to the non-detection state, it can be determined that the medium 15 cannot be discharged into the medium storage device 12. The control unit 21 may also stop recording at the timing when the recorded medium 15 is discharged, if the detection unit 45 does not return to the non-detection state.

[0068] The role of implementation

[0069] The operation of this embodiment will be described.

[0070] When the medium storage device 12 is installed, the detection unit 45 is in a non-detection state. When the medium storage device 12 is removed, the detection unit 45 is in a detection state. Therefore, the detection unit 45 can detect the installation and removal of the medium storage device 12.

[0071] While the medium storage device 12 is installed, the detection unit 45 does not detect the installation detection member 46. Therefore, the detection unit 45 can detect the displacement of the detection auxiliary member 49. That is, while the medium storage device 12 is installed, the detection unit 45 detects the medium 15. When the medium storage device 12 is not installed, the detection unit 45 does not detect the medium 15.

[0072] Effects of implementation methods

[0073] The effects of this embodiment will be described.

[0074] (1-1) The swingable position of the contact member 48 can be changed by rotating the rotating shaft 39 having the protrusion 57. Therefore, since the recording device 13 can be configured with a small number of parts, the medium 15 can be detected with a simple structure.

[0075] (1-2) The detection unit 45 detects the detection auxiliary member 49 that is displaced in conjunction with the contact member 48. Therefore, the degree of freedom in the arrangement of the detection unit 45 can be increased.

[0076] (1-3) Since the detection auxiliary member 49 rotates in conjunction with the displacement of the contact member 48 , the detection auxiliary member 49 can be easily displaced.

[0077] (1-4) When the discharge unit 38 clamps the medium 15, the rotation axis 39 may move depending on the thickness of the medium 15. In this regard, since the contact surface 62 is formed along the direction in which the rotation axis 39 moves, it can accommodate the movement of the rotation axis 39.

[0078] (1-5) When the discharge unit 38 is at the non-gripping position P2, the detection auxiliary member 49 is at a position not detected by the detection unit 45. Therefore, when the discharge unit 38 is at the non-gripping position P2, the detection unit 45 can be used for detection other than the detection auxiliary member 49.

[0079] (1-6) The detection unit 45 detects displacement of the mounting detection member 46. The mounting detection member 46 is displaced as the medium storage device 12 is attached or detached. Therefore, the detection unit 45 can detect the ejected medium 15 and the attachment or detachment of the medium storage device 12.

[0080] (1-7) The installation detection component 46 is detected by the detection unit 45 when the medium storage device 12 is not installed. The installation detection component 46 is displaced when the medium storage device 12 is installed. That is, the installation detection component 46 can be displaced to a position where it is not detected by the detection unit 45 as the medium storage device 12 is installed.

[0081] (1-8) The mounting detection member 46 and the detection auxiliary member 49 are axially supported on the same shaft and detected by the same detection unit 45. Therefore, the detection of the mounting detection member 46 and the detection auxiliary member 49 can be stabilized.

[0082] Change Example

[0083] This embodiment can be modified and implemented in the following forms. This embodiment and the following modified examples can be combined and implemented with each other within the scope of no technical contradiction.

[0084] The mounting detection member 46 may be provided so as to slide relative to the first shaft 55. The detection auxiliary member 49 may be provided so as to slide relative to the second shaft 66. In the case where at least one of the mounting detection member 46 and the detection auxiliary member 49 slides relative to the shaft, the first shaft 55 and the second shaft 66 may be integrally formed.

[0085] The first axis 55 and the second axis 66 may be provided at arbitrary positions. The first axis 55 and the second axis 66 may not be parallel to each other.

[0086] The mounting detection member 46 may also slide and move as the medium storage device 12 is mounted or removed.

[0087] The recording device 13 may include a plurality of detection units 45. The recording device 13 may include a detection unit 45 that detects the displacement of the mounting detection member 46 and a detection unit 45 that detects the displacement of the detection auxiliary member 49, respectively.

[0088] When the medium storage device 12 is not installed, the installation detection member 46 may be located at a position not detected by the detection unit 45. When the medium storage device 12 is installed, the installation detection member 46 may be located at a position detected by the detection unit 45.

[0089] The recording device 13 may be configured not to include the mounting detection member 46. The detection unit 45 may not detect the displacement of the mounting detection member 46. The detection unit 45 may directly detect the mounted medium storage device 12.

[0090] When the discharge unit 38 is located at the non-gripping position P2 , the detection auxiliary member 49 may be located at a position to be detected by the detection unit 45 .

[0091] The contact surface 62 may be formed so as to be along a direction different from the direction in which the rotation shaft 39 moves when the medium 15 is nipped between the driven roller 42 and the discharge roller 41 at the nip position P1 .

[0092] The detection auxiliary member 49 may slide in conjunction with the displacement of the contact member 48 .

[0099] Notes

[0100] Hereinafter, the technical ideas and the effects thereof understood from the above-described embodiments and modifications will be described.

[0101] (A) A recording device, comprising: a recording unit that records on a medium; a discharge unit that clamps and discharges the recorded medium; a rotating shaft that rotates the discharge unit to a clamping position where the medium can be clamped and a non-clamping position where the medium cannot be clamped; an abutment member that swings around the rotating shaft and can abut against the discharged medium; and a detection unit that detects the displacement of the abutment member, the rotating shaft having a protrusion that engages with the abutment member, the abutment member having a swing limiting member that limits the swinging range by engaging with the protrusion, the protrusion changing the position of engagement with the swing limiting member as the rotating shaft rotates, and the swingable position of the abutment member changes when the discharge unit is in the clamping position and when the discharge unit is in the non-clamping position.

[0102] According to this structure, the swingable position of the contact member can be changed by rotating the rotating shaft having the protrusion. Therefore, since the recording device can be constructed with a small number of parts, the medium can be detected with a simple structure.

[0103] (B) In the recording device described in (A), the following method may be adopted, that is, there is a detection auxiliary component, the detection auxiliary component abuts against the abutment component and displaces in a manner linked to the displacement of the abutment component, and the detection unit detects the detection auxiliary component.

[0104] According to this configuration, the detection unit detects the detection auxiliary member that is displaced in conjunction with the contact member. Therefore, the degree of freedom in the arrangement of the detection unit can be increased.

[0105] (C) In the recording device described in (B), the detection auxiliary member may be axially supported on an axis different from the rotation axis and rotated in conjunction with the displacement of the contact member.

[0106] According to this configuration, since the detection auxiliary member rotates in conjunction with the displacement of the contact member, the detection auxiliary member can be easily displaced.

[0107] (D) In ​​the recording device described in (B) or (C), the following method may also be adopted, that is, the abutment component has an abutment surface that abuts against the detection auxiliary component, and the abutment surface is formed so that when the discharge part is located in the clamping position, the direction of the discharge part changes along the rotating axis accompanied by the clamping of the medium.

[0108] When the discharge unit clamps the medium, the rotation axis may change depending on the thickness of the medium. In this regard, according to this structure, since the contact surface is formed along the direction in which the rotation axis changes, the change of the rotation axis can be avoided.

[0109] (E) In the recording apparatus described in (B) to (D), the following mode may be adopted: when the discharge unit is located at the non-clamping position, the detection auxiliary member is located at a position not detected by the detection unit.

[0110] According to this configuration, when the discharge unit is in the non-clamping position, the detection auxiliary member is in a position not detected by the detection unit. Therefore, when the discharge unit is in the non-clamping position, the detection unit can be used for detection other than the detection auxiliary member.

[0111] (F) In the recording device described in (A) to (E), the following method may be adopted, that is, there is an installation detection component, the installation detection component is displaced along with the installation and removal of the medium storage device that loads the discharged medium, and the detection unit detects the displacement of the installation detection component.

[0112] According to this structure, the detection unit detects the displacement of the mounting detection member. The mounting detection member is displaced along with the attachment and detachment of the medium storage device. Therefore, the detection unit can detect the discharged medium and the attachment and detachment of the medium storage device.

[0113] (G) In the recording device described in (F), the following mode may be adopted: when the medium storage device is not installed, the installation detection member is located at a position detected by the detection unit.

[0114] According to this structure, the installation detection component is detected by the detection unit when the medium storage device is not installed. The installation detection component is displaced when the medium storage device is installed. That is, the installation detection component can be displaced to a position where it is not detected by the detection unit as the medium storage device is installed.

[0115] (H) In the recording device described in (C) to (E), the following method may also be adopted, that is, there is an installation detection component, the installation detection component is displaced along with the installation and removal of the medium storage device that loads the discharged medium, the detection unit detects the displacement of the installation detection component, the installation detection component is axially supported on the same axis as the detection auxiliary component, and rotates in a manner linked to the installation and removal of the medium storage device.

[0116] According to this structure, the mounting detection member and the detection auxiliary member are axially supported on the same shaft and detected by the same detection unit. Therefore, the detection of the mounting detection member and the detection auxiliary member can be stabilized.
