Description

[Technical field]

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

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

[0003] A stacker, which is an example of a medium storage device, is removably attached to the recording device. When the stacker is not attached, the driven roller is located at a position separated from the drive roller.

[0004] When media is discharged to the stacker, the second rotating shaft is rotated to move the driven roller to a position where it can pinch the media between itself and the drive roller. The load detection mechanism moves the detection auxiliary member to the detection position in conjunction with the movement of the driven roller, thereby enabling the amount of media loaded on the stacker to be detected.

[0009] [Embodiment] Hereinafter, an 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, for example, an inkjet printer that ejects ink, which is an example of a liquid, onto a medium such as paper, fabric, or vinyl to record.

[0010] In the drawings, the recording system 11 is assumed to be placed on a horizontal plane, the direction of gravity is indicated by the Z axis, and directions along the horizontal plane are indicated by the X axis and the Y axis. The X axis, the Y axis, and the Z axis are perpendicular to each other. In the following description, the direction parallel to the X axis is also referred to as the width direction X.

[0011] <Recording System> As shown in FIG. 1, a recording system 11 includes a medium accommodation device 12 and a recording device 13.

[0012] <Media storage device> The medium storage device 12 is detachably attached to the recording device 13. The medium storage device 12 attached to the recording device 13 is capable of loading the medium 15 discharged from the recording device 13. The medium storage device 12 may have a discharge tray 16, a pressing unit 17, and an arm 18.

[0013] 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. The pressing portion 17 presses the medium 15 loaded on the discharge tray 16 .

[0014] When the medium accommodating device 12 is attached to the recording device 13, the arm 18 may be inserted into the recording device 13 to position the medium accommodating device 12 with respect to the recording device 13. The arm 18 may abut against the recording device 13 when the medium accommodating device 12 is attached to the recording device 13.

[0015] <Recording device> The recording device 13 may include a housing 20, a control unit 21, a feed unit 22, a transport unit 23, a recording unit 24, a support unit 25, a cutting unit 26, and a discharge mechanism 27.

[0016] The housing 20 houses various components of the recording device 13. The housing 20 may have an outlet 29 through which the recorded medium 15 is discharged. The medium storage device 12 may be attached to the outlet 29.

[0017] The control unit 21 comprehensively controls the driving of each mechanism in the recording device 13 and controls various operations executed by the recording device 13 . The control unit 21 may be configured as a circuit including: α: one or more processors that execute various processes according to a computer program; β: one or more dedicated hardware circuits that execute at least some of the various processes; or γ: a combination thereof. The hardware circuit is, for example, an application specific integrated circuit. The processor includes a CPU and memory such as RAM and ROM, and the memory stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer readable medium, includes any readable medium that can be accessed by a general-purpose or dedicated computer.

[0018] The payout unit 22 may include one or more payout spindles 31. The payout spindle 31 rotatably supports a roll body 32. The roll body 32 is a long medium 15 wound and stacked into a cylindrical shape. The payout spindle 31 pays out the medium 15 by rotating the roll body 32. When the payout unit 22 includes multiple payout spindles 31, the payout unit 22 rotates one payout spindle 31 that supports the medium 15 to be paid out.

[0019] 1. Transport unit 23 may transport medium 15 by sandwiching medium 15 between a pair of rotating rollers. Transport unit 23 transports medium 15 in transport direction Dc. Transport direction Dc is a direction along transport path 34.

[0020] The recording unit 24 records on the medium 15. The recording unit 24 may record on the medium 15 by ejecting liquid from a nozzle (not shown). The support section 25 supports the portion of the long medium 15 that is to be recorded on the recording section 24 .

[0021] The cutting unit 26 is provided downstream in the transport direction Dc from the recording unit 24. The cutting unit 26 is capable of cutting the recorded medium 15 across the width direction X. The cutting unit 26 may cut the medium 15 by moving a pair of cutting blades 36 in the width direction X.

[0022] <Ejection mechanism> As shown in FIG. 1, the ejection mechanism 27 may include an ejection portion 38 and a rotating shaft 39. As shown in FIG. 2, the discharge unit 38 may include a discharge roller 41, a driven roller 42, and a holding unit 43.

[0023] The discharge roller 41 rotates in response to the driving of a motor (not shown). 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 that comes into contact with the recorded surface of the medium 15 is a toothed roller, deterioration of recording quality can be suppressed.

[0024] The holder 43 rotatably holds the driven roller 42. The holder 43 is fixed to the rotating shaft 39 so as to rotate integrally with the rotating shaft 39. The rotation means a rotation about the shaft, and the rotatable angle is less than 360 degrees.

[0025] The rotating shaft 39 can rotate in a first rotation direction R1 and a second rotation direction R2. The first rotation direction R1 is opposite to the second rotation direction R2. The rotating shaft 39 rotates the discharge unit 38 between a clamping position P1 shown in FIG. 1 and a non-clamping position P2 shown in FIG. 2. Specifically, the rotating shaft 39 rotates the holding unit 43 to move the driven roller 42. When the rotating shaft 39 rotates in the first rotation direction R1 from a state in which the discharge unit 38 is located at the non-clamping position P2, the holding unit 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 a state in which the discharge unit 38 is located at the clamping position P1, the holding unit 43 and the driven roller 42 move to the non-clamping position P2.

[0026] The clamping position P1 is a position where the driven roller 42 approaches the discharge roller 41. The clamping position P1 is a position where the medium 15 can be clamped. Non-clamping position P2 is a position where driven roller 42 is separated from discharge roller 41. Non-clamping position P2 is a position where medium 15 cannot be clamped.

[0027] The discharge unit 38 clamps and discharges the recorded medium 15. The discharge unit 38 may clamp the medium 15 between a discharge roller 41 and a driven roller 42 and discharge the medium 15 from the discharge opening 29 by rotating the discharge roller 41.

[0028] Discharge unit 38 may be located at clamping position P1 when cutting unit 26 cuts medium 15. Discharge unit 38 may clamp cut medium 15 between discharge roller 41 and driven roller 42 and discharge it. Discharge unit 38 may be located at non-clamping position P2 when cutting unit 26 does not cut medium 15. Discharge unit 38 may discharge uncut long medium 15 by discharge roller 41.

[0029] As shown in FIG. 2, the ejection mechanism 27 may include a detection unit 45, an attachment detection member 46, a spring 47, a contact member 48, and an auxiliary detection member 49. The detection unit 45 is, for example, a photoelectric sensor including a light-projecting unit and a light-receiving unit. The detection unit 45 may detect the displacement of the attachment detection member 46, the contact member 48, and the detection auxiliary member 49. The detection unit 45 of this embodiment detects the displacement of each member depending on whether the optical axis 51 is blocked or not. 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.

[0030] 3, the attachment detection member 46 may have a first lever 53 and a first flag 54. The attachment detection member 46 is displaced in association with the attachment or detachment of the medium storage device 12. The attachment detection member 46 of the present embodiment is provided rotatable about a first shaft 55. The attachment detection member 46 rotates in association with the attachment or detachment of the medium storage device 12.

[0031] 2 and 3, when the medium storage device 12 is not installed in the recording device 13, the installation detection member 46 is located at the non-installed position P3. When the installation detection member 46 is located at the non-installed position P3, the first flag 54 blocks the optical axis 51. In other words, when the medium storage device 12 is not installed, the installation detection member 46 is located at a position where it can be detected by the detection unit 45.

[0032] As shown in FIG. 4, when the medium storage device 12 is attached to the recording device 13, the arm 18 presses the first lever 53. The attachment detection member 46 rotates about the first shaft 55 to move to the attachment position P4. When the attachment detection member 46 moves to the attachment position P4, the first flag 54, which rotates about the first shaft 55, moves away from the detection unit 45. In other words, when the medium storage device 12 is attached, the attachment detection member 46 is in a position where it is not detected by the detection unit 45. When the discharge unit 38 is in the non-clamping position P2, the detection unit 45 detects that the attachment detection member 46 has changed from a detection state to a non-detection state, so that the recording device 13 can detect that the medium storage device 12 has been attached.

[0033] The spring 47 pushes the attachment detection member 46 located at the attachment position P4 toward the non-attached position P3. Therefore, when the medium accommodation device 12 is removed from the recording device 13, the attachment detection member 46 returns to the non-attached position P3.

[0034] The rotating shaft 39 has a protrusion 57. The protrusion 57 engages with the abutment member . The abutting member 48 is provided with a swing limiting portion 58. The protrusion 57 may be provided within the swing limiting portion 58. The abutting member 48 is swingable by contacting the medium 15 discharged from the discharge port 29, and the swing limiting portion 58 engages with the protrusion 57 to limit the range in which the abutting member 48 swings. The swing limiting portion 58 may have a first wall 59 and a second wall 60. The protrusion 57 changes its position around the rotation shaft 39 as the rotation shaft 39 rotates. As the position of the protrusion 57 changes, the position at which the protrusion 57 and the swing limiting portion 58 engage changes, and the position in which the abutting member 48 can swing changes.

[0035] The abutment member 48 swings around the pivot 39. The abutment member 48 is not fixed to the pivot 39. The abutment member 48 slides relative to the pivot 39. The abutment member 48 is supported by the pivot 39 at a position away from the center of gravity of the abutment member 48. The abutment member 48 tries to swing so that the portion in contact with the medium 15 moves downward, but the position of the protrusion 57 may limit the swing of the abutment member 48. For example, the first wall 59 of the swing limiting portion 58 and the protrusion 57 can be brought into contact with each other to limit the swing of the abutment member 48 so that the portion in contact with the medium 15 does not move downward. The abutment member 48 may have an abutment surface 62. The abutment surface 62 abuts against the detection auxiliary member 49.

[0036] As shown in FIG. 3, the detection auxiliary member 49 may have a second lever 64 and a second flag 65. The detection auxiliary member 49 abuts against the abutment member 48. Specifically, the second lever 64 of the detection auxiliary member 49 abuts against the abutment surface 62. Abutment means contact so as to come into contact with the abutment member 48. The detection auxiliary member 49 is displaced in conjunction with the displacement of the abutment member 48. The detection auxiliary member 49 of this embodiment is provided rotatably about a second shaft 66. The detection auxiliary member 49 rotates in conjunction with the displacement of the abutment member 48.

[0037] The first shaft 55 and the second shaft 66 are capable of rotating separately. The first shaft 55 and the second shaft 66 may be provided so that their respective axes are aligned in a straight line. The attachment detection member 46 may be supported on the same axis as the auxiliary detection member 49. The attachment detection member 46 and the auxiliary detection member 49 may be supported on an axis different from the rotation shaft 39.

[0038] 4, when the discharge unit 38 is located at the non-clamping position P2, the detection auxiliary member 49 may be located at a position where it is not detected by the detection unit 45. When the discharge unit 38 is located at the clamping position P1, the detection auxiliary member 49 is movable between a position where it is detected by the detection unit 45 and a position where it is not detected.

[0039] 4, the abutment member 48 is located at the initial position P5. The protrusion 57 presses the first wall 59 to position the abutment member 48 at the initial position P5. The second lever 64 of the detection auxiliary member 49 abuts on the abutment surface 62. The second flag 65 of the detection auxiliary member 49 is located above the detection portion 45. The second flag 65 does not block the optical axis 51.

[0040] That is, when the medium storage device 12 is installed in the recording device 13 and the installation detection member 46 moves to the installation position P4, the detection unit 45 enters a non-detection state in which it does not detect the first flag 54 and the second flag 65, and can detect that the medium storage device 12 has been installed. Upon detecting that the medium storage device 12 has been installed, the control unit 21 rotates the rotating shaft 39 in the first rotation direction R1. When the rotating shaft 39 rotates in the first rotation direction R1, the discharge mechanism 27 is in the state shown in FIG. 5. Even when the rotating shaft 39 rotates in the first rotation direction R1, the installation detection member 46 remains located at the installation position P4.

[0041] 5, 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.

[0042] The range in which the abutment member 48 can swing is between the position where the first wall 59 hits the protrusion 57 and the position where the second wall 60 hits the protrusion 57 when the abutment member 48 swings about the rotation shaft 39. Therefore, when the rotation shaft 39 rotates and the position of the protrusion 57 changes, the position in which the abutment member 48 can swing changes. When the rotation shaft 39 rotates, the position of the discharge portion 38 changes. Therefore, the position in which the abutment member 48 can swing changes between when the discharge portion 38 is located at the clamping position P1 and when it is located at the non-clamping position P2. That is, the position at which the first wall 59 or the second wall 60 is restricted from rotating relative to the protrusion 57 around the axis of the rotation shaft 39 changes. Therefore, the angle position at which the abutment member 48 is restricted from rotating around the rotation shaft 39 changes.

[0043] When the ejection portion 38 changes from a state in which it is located at the non-clamping position P2 to a state in which it is located at the clamping position P1, the protrusion 57 rotates and moves away from the first wall 59, and the tip 68 of the abutting member 48 moves down due to its own weight. The abutting member 48 may move to a lower limit position P6 and come into contact with a positioning portion (not shown), thereby restricting its rotation in the first rotation direction R1. At this time, the angle by which the abutting member 48 rotates may be smaller than the angle by which the rotation shaft 39 rotates. The protrusion 57 may move away from the first wall 59. The protrusion 57 may also move away from the second wall 60.

[0044] The detection auxiliary member 49 moves along the abutment surface 62 of the rotating abutment member 48. The detection auxiliary member 49 rotates about the second axis 66, and the second flag 65 passes through the detection unit 45. When the abutment member 48 is located at the lower limit position P6, the detection auxiliary member 49 is positioned such that the second flag 65 is lower than the detection unit 45. The second flag 65 does not block the optical axis 51. Therefore, when the second flag 65 passes through the detection unit 45, the detection unit 45 switches between a non-detection state, a detection state, and a non-detection state in that order.

[0045] The second flag 65 and the first flag 54 can rotate independently 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 they rotate about the same axis, the second flag 65 and the first flag 54 can be easily adjusted.

[0046] The contact member 48 at the lower limit position P6 is capable of coming into contact with the discharged medium 15. In other words, the contact member 48 is capable of being positioned at a position through which the discharged medium 15 passes. 6, the contact member 48 that the medium 15 hits 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 flag 65 of the detection auxiliary member 49 blocks the optical axis 51. The detection unit 45 enters the detection state.

[0047] The pivot shaft 39 may move in association with the ejection unit 38 clamping the medium 15. When the ejection unit 38 is located at the clamping position P1, and the ejection roller 41 and the driven roller 42 clamp the medium 15, the driven roller 42 moves away from the ejection roller 41 by the thickness of the medium 15. The holder 43 is pushed by the movement of the driven roller 42 and tends to move, so that the pivot shaft 39 that fixes the holder 43 is also pushed. Therefore, the pivot shaft 39 may be movable in a direction away from the ejection roller 41 by the thickness of the medium 15. The contact surface 62 may be formed so as to follow the direction in which the pivot shaft 39 moves as the ejection unit 38 clamps the medium 15 when the ejection unit 38 is rotated to the clamping position P1. That is, the abutment surface 62 of the abutment member 48 and the second lever 64 of the detection auxiliary member 49 are in contact with each other so as to slide along the direction in which the rotation shaft 39 moves as the medium 15 is clamped. Since the detection auxiliary member 49 rotates on an axis different from that of the rotation shaft 39, the rotation of the detection auxiliary member 49 is not affected even if the rotation shaft 39 moves.

[0048] 5, 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, so that the detector 45 goes into a non-detection state. However, in cases where medium 15 remains in discharge section 38, where medium 15 discharged to medium storage device 12 deforms and contacts contact member 48, or where more than the maximum amount of medium 15 is stacked on discharge tray 16, medium 15 may remain in contact with contact member 48. In other words, detection section 45 may not return to the non-detection state. If detection section 45 does not return to the non-detection state when discharge section 38 discharges medium 15, it can be determined that medium 15 can no longer be discharged to medium storage device 12. If detection section 45 does not enter the non-detection state at the time when recorded medium 15 is discharged, control section 21 may stop recording.

[0049] <Operation of the embodiment> The operation of this embodiment will be described. When the medium storage device 12 is attached, the detection unit 45 goes into a non-detection state. When the medium storage device 12 is removed, the detection unit 45 goes into a detection state. Therefore, the detection unit 45 can detect the attachment and detachment of the medium storage device 12.

[0050] 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. In other words, while the medium storage device 12 is installed, the detection unit 45 detects the medium 15. If the medium storage device 12 is not installed, the detection unit 45 does not detect the medium 15.

[0051] <Effects of the embodiment> The effects of this embodiment will be described. (1-1) The pivotable position of the contact member 48 can be changed by rotating the pivot shaft 39 having the protrusion 57. Therefore, the recording device 13 can be configured with a small number of parts, and the medium 15 can be detected with a simple configuration.

[0052] (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 arranging the detection unit 45 can be increased. (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.

[0053] (1-4) When the discharge portion 38 clamps the medium 15, the rotation axis 39 may fluctuate depending on the thickness of the medium 15. In this regard, the contact surface 62 is formed along the direction in which the rotation axis 39 fluctuates, and therefore can deflect the fluctuation of the rotation axis 39.

[0054] (1-5) When the discharge unit 38 is located at the non-clamping position P2, the detection auxiliary member 49 is located at a position where it cannot be detected by the detection unit 45. Therefore, when the discharge unit 38 is located at the non-clamping position P2, the detection unit 45 can be used for detecting something other than the detection auxiliary member 49.

[0055] (1-6) The detection unit 45 detects the displacement of the attachment detection member 46. The attachment detection member 46 is displaced in association with the attachment or detachment of the medium storage device 12. Therefore, the detection unit 45 can detect the ejected medium 15 and the attachment or detachment of the medium storage device 12.

[0056] (1-7) The attachment detection member 46 is detected by the detection unit 45 when the medium storage device 12 is not attached. The attachment detection member 46 is displaced when the medium storage device 12 is attached. In other words, the attachment detection member 46 can be displaced to a position where it is not detected by the detection unit 45 as the medium storage device 12 is attached.

[0057] (1-8) The attachment detection member 46 and the detection auxiliary member 49 are supported on the same axis and are detected by the same detection unit 45. Therefore, the detection of the attachment detection member 46 and the detection auxiliary member 49 can be stabilized.

[0058] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0059] The attachment 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. When at least one of the attachment 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 configured as a single unit.

[0060] The first shaft 55 and the second shaft 66 may be provided at any position. The first shaft 55 and the second shaft 66 do not have to be parallel to each other. The attachment detection member 46 may slide when the medium container 12 is attached or detached.

[0061] 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 attachment detection member 46, and a detection unit 45 that detects the displacement of the detection auxiliary member 49.

[0062] When the medium storage device 12 is not installed, the installation detection member 46 may be in a position that is not detected by the detection unit 45. When the medium storage device 12 is installed, the installation detection member 46 may be in a position that is detected by the detection unit 45.

[0063] The recording device 13 may be configured without including the attachment detection member 46. The detection unit 45 may not detect the displacement of the attachment detection member 46. The detection unit 45 may directly detect the medium accommodation device 12 that is attached.

[0064] When the discharge unit 38 is located at the non-clamping position P2, the detection auxiliary member 49 may be located at a position where it can be detected by the detection unit 45. The contact surface 62 may be formed to follow a direction different from the direction in which the pivot shaft 39 moves when the driven roller 42, located at the clamping position P1, clamps the medium 15 between itself and the discharge roller 41.

[0065] The detection auxiliary member 49 may slide in conjunction with the displacement of the contact member 48 . The discharge mechanism 27 may not include the detection auxiliary member 49. The detection unit 45 may directly detect the contact member .

[0066] The discharge roller 41 may be held by a holding portion 43. The discharge roller 41 may move together with the driven roller 42 between the clamping position P1 and the non-clamping position P2. The recording device 13 is not limited to an inkjet printer, but may be a laser printer, a thermal printer, a dot matrix printer, a digital printing machine, or the like.

[0067] The recording device 13 may be a liquid ejection device that performs recording by ejecting or discharging a liquid other than ink.

[0069] [Note] The technical ideas and effects obtained from the above-described embodiment and modified examples will be described below.

[0070] (A) A recording device includes a recording unit that records on a medium, an ejection unit that clamps and ejects the recorded medium, a rotation axis that rotates the ejection unit between a clamping position where the medium can be clamped and a non-clamping position where the medium cannot be clamped, a contact member that swings around the rotation axis and can abut against the medium being ejected, and a detection unit that detects the displacement of the contact member, wherein the rotation axis has a protrusion that engages with the contact member, and the abutment member is provided with a swing limiting portion that engages with the protrusion to limit the range of swing, and the position at which the protrusion engages with the swing limiting portion changes as the rotation axis rotates, and the position at which the abutment member can swing changes between when the ejection unit is in the clamping position and when it is in the non-clamping position.

[0071] According to this configuration, the position to which the contact member can swing can be changed by rotating the rotating shaft having the protrusion. Therefore, the recording device can be configured with a small number of parts, and the medium can be detected with a simple configuration.

[0072] (B) The recording device described in (A) may have a detection auxiliary member that abuts against the abutting member and is displaced in conjunction with the displacement of the abutting member, and the detection section may detect the detection auxiliary member. According to this configuration, the detection section detects the detection auxiliary member that is displaced in conjunction with the contact member, which increases the degree of freedom in arranging the detection section.

[0073] In the recording device described in (C) and (B), the detection auxiliary member may be supported on an axis different from the rotation axis and rotate in conjunction with the displacement of the contact member. According to this configuration, the detection auxiliary member rotates in conjunction with the displacement of the abutment member, so that the detection auxiliary member can be easily displaced.

[0074] In the recording device described in (D)(B) or (C), the abutment member may have an abutment surface that abuts against the detection auxiliary member, and the abutment surface may be formed so as to align with the direction in which the rotation axis moves as the ejection portion clamps the medium when the ejection portion is located at the clamping position.

[0075] When the ejection section clamps the medium, the rotation axis may fluctuate depending on the thickness of the medium. In this regard, with this configuration, the contact surface is formed along the direction in which the rotation axis fluctuates, so that the fluctuation of the rotation axis can be deflected.

[0076] (E) In the recording device described in (B) to (D), when the discharge section is located at the non-clamping position, the detection auxiliary member may be located at a position where it is not detected by the detection section. According to this configuration, when the discharge section is in the non-clamping position, the detection auxiliary member is in a position where it cannot be detected by the detection section, and therefore, when the discharge section is in the non-clamping position, the detection section can be used for detecting something other than the detection auxiliary member.

[0077] (F) The recording device described in (A) to (E) may include an attachment detection member that is displaced in association with the attachment or detachment of a medium storage device that holds the ejected medium, and the detection unit may detect the displacement of the attachment detection member.

[0078] According to this configuration, the detection unit detects the displacement of the attachment detection member. The attachment detection member is displaced in association with the attachment or detachment of the medium storage device. Therefore, the detection unit can detect the ejected medium and the attachment or detachment of the medium storage device.

[0079] In the recording device described in (G) and (F), when the medium storage device is not mounted, the mounting detection member may be in a position where it can be detected by the detection section. According to this configuration, the attachment detection member is detected by the detection unit when the medium storage device is not attached. The attachment detection member is displaced when the medium storage device is attached. In other words, the attachment detection member can be displaced to a position where it is not detected by the detection unit as the medium storage device is attached.

[0080] The recording device described in (H)(C) to (E) is provided with an attachment detection member that is displaced in association with the attachment or detachment of a media storage device that holds the ejected media, and the detection unit detects the displacement of the attachment detection member, which is supported on the same axis as the detection auxiliary member and rotates in conjunction with the attachment or detachment of the media storage device.

[0081] According to this configuration, the attachment detection member and the detection auxiliary member are supported on the same axis and are detected by the same detector, thereby making it possible to stabilize detection of the attachment detection member and the detection auxiliary member.
