Printing apparatus

Abstract

This invention provides a printing apparatus. The challenge lies in the fact that the linkage mechanism for opening a tray cover in conjunction with the rotation of a scanner unit has multiple components and a complex structure, making it difficult to reduce the number of components. The printing apparatus includes: a print head; a main housing; a scanner unit having an original document stage and capable of rotating about a first rotation axis to a closed state and an open state; and a supply mask capable of rotating about a second rotation axis to a closed position (closing the media supply port) and an open position (opening the media supply port). When the scanner unit changes from the closed state to the open state, the supply mask moves from the closed position to the open position by abutting abutting abutting part of the scanner unit against abutting part of the supply mask.

Description

Technical Field

[0001] This disclosure relates to a printing apparatus. Background Technology

[0002] A multifunction printer comprising a scanner unit and a printer unit is known. The multifunction printer is an example of a printing apparatus. The multifunction printer described in Patent Document 1 includes a frame for the scanner unit, a housing for the printer unit, and a rotating component as a linkage mechanism. An original document cover is rotatably mounted on the frame of the scanner unit. The frame of the scanner unit rotates relative to the frame of the printer unit.

[0033] Figure 1 and Figure 2 The external structure of printer 10 is shown. Printer 10 is a multifunction printer with functions for reading original documents and printing media. Printer 10 may also have functions such as faxing. Printer 10 is an inkjet printer that prints by ejecting ink onto media. Printer 10 corresponds to an example of a printing apparatus. Figure 1 A perspective view of printer 10 from the front. Figure 2 A perspective view of printer 10 from the rear.

[0034] include Figure 1 Several accompanying figures illustrate the XYZ coordinate system. The Z-axis is perpendicular to the setting surface of the printer 10. The +Z direction is the direction upward from the setting surface. The -Z direction is the direction upward towards the setting surface. The X-axis is perpendicular to the Z-axis. The X-axis is the axis of rotation 13R of the image reading unit, described later. The +X direction is the direction from left to right when viewing the printer 10 from an opposing position opposite the front surface of the control panel 19, described later. The -X direction is the direction from right to left when viewing the printer 10 from the opposing position. The Y-axis is perpendicular to both the X-axis and the Z-axis. The +Y direction is the direction from the rear surface of the printer 10 towards the front surface. The front surface is the surface with the control panel 19. The rear surface is the surface opposite to the front surface. The -Y direction is the direction from the front surface of the printer 10 towards the rear surface.

[0035] like Figure 1 as well as Figure 2 As shown, the printer 10 includes a printer housing 11, an image reading unit 13, a document tray cover 15, a supply channel cover 17, and a control panel 19.

[0036] The printer housing 11 is a frame that houses the transport section 30 and the recording section 60, including the recording head 62. The transport section 30, the recording head 62, and the recording section 60 will be described later. The printer housing 11 corresponds to an example of the main housing. The printer housing 11 supports the image reading unit 13 and the supply channel cover 17 in a rotatable manner.

[0037] Image reading unit 13 reads the original document. Image reading unit 13 corresponds to an example of a scanner unit. Image reading unit 13 is positioned in the +Z direction of printer housing 11. Image reading unit 13 is configured to rotate relative to printer housing 11 to a shielded state CS and an open state OS. Shielded state CS is a state in which image reading unit 13 is closed and shields printer housing 11. Shielded state CS corresponds to an example of a closed state. In shielded state CS, image reading unit 13 is in a state where printer housing 11 is closed. Open state OS is a state in which image reading unit 13 opens printer housing 11 and opens the interior of printer housing 11. Open state OS corresponds to an example of an open state. In open state OS, image reading unit 13 is in a state where printer housing 11 is open. Image reading unit 13 supports original document stage 15 in a rotatable manner. Figure 1 and Figure 2 The image reading unit 13 in the occluded state CS is shown.

[0038] The original document stage cover 15 covers the +Z direction surface of the image reading unit 13. The original document stage cover 15 corresponds to an example of an original document stage cover. The original document stage cover 15 is positioned at a +Z direction location on the image reading unit 13. The original document stage cover 15 is configured to rotate relative to the image reading unit 13 to a contact position CP and a separation position SP. The contact position CP is the position where the original document stage cover 15 contacts and blocks the original document stage 23. The contact position CP corresponds to an example of a blocking position. The separation position SP is the position where the original document stage cover 15 separates from the original document stage 23, allowing the original document stage 23 to open. The separation position SP corresponds to an example of an open position. Figure 1 and Figure 2 The original document stage cover 15 at the contact position CP is shown.

[0039] The supply channel cover 17 covers the supply port 51, described later. The supply channel cover 17 corresponds to one example of a supply mask. The supply channel cover 17 is positioned in the -Y direction and the +Z direction of the printer housing 11. The supply channel cover 17 is configured to rotate to a first position P1 and a second position P2. The first position P1 is the position where the supply channel cover 17 closes the supply port 51, and is a position that prevents the user from supplying media from the supply port 51. The first position P1 corresponds to one example of a closed position. The second position P2 is the position where the supply channel cover 17 opens the supply port 51, and is a position that allows the user to supply media into the printer housing 11. The second position P2 corresponds to one example of an open position. Figure 1 and Figure 2 The supply channel cover 17 at the first position P1 is shown.

[0040] Control panel 19 is subject to user input. Control panel 19 displays various information. Control panel 19 includes a display panel, input buttons, etc. The display panel may also have touch input functionality. Control panel 19 is positioned on the +Y plane of printer 10.

[0041] Figure 3 The external structure of printer 10 is shown. Figure 3 Printer 10 is shown when viewed from above in the +Z direction. Figure 3 The original document tray cover 15, the supply channel cover 17, and the control panel 19 are shown. Figure 3 The original document stage cover 15 at the contact position CP is shown. Figure 3 The supply channel cover 17 at the first position P1 is shown.

[0042] The supply channel cover 17 is positioned in the -Y direction relative to the document stage cover 15 when viewed from above in the +Z direction. The -Y direction corresponds to an example of the first direction. The document stage cover 15 and the supply channel cover 17 cover the image reading unit 13 so that the image reading unit 13 is not visible when viewed from above in the +Z direction.

[0043] Figure 4 The external structure of printer 10 is shown. Figure 4 The printer 10 is shown as viewed from the +X direction. Figure 4 The printer housing 11, image reading unit 13, original document tray cover 15, and supply channel cover 17 are shown. Figure 4 The image reading unit 13 in the occluded state CS is shown. Figure 4 The original document stage cover 15 at the contact position CP is shown. Figure 4 The supply channel cover 17 at the first position P1 is shown.

[0044] Figure 4The upper surface 15s of the document stage cover and the upper surface 17s of the supply channel cover are shown. The upper surface 15s of the document stage cover is the face of the document stage cover 15 in the +Z direction. The upper surface 15s of the document stage cover corresponds to an example of the upper surface of the document stage cover. The upper surface 17s of the supply channel cover is the face of the supply channel cover 17 in the +Z direction. The upper surface 17s of the supply channel cover corresponds to an example of the upper surface of the supply mask.

[0045] The height position along the Z-axis of the upper surface 15s of the original document platform cover is the same as or approximately the same as the height position along the Z-axis of the upper surface 17s of the supply channel cover. The upper surface 17s of the supply channel cover and the upper surface 15s of the original document platform cover are located on the same plane. The upper surface 17s of the supply channel cover and the upper surface 15s of the original document platform cover are in a state with no height difference. By making the upper surface 17s of the supply channel cover and the upper surface 15s of the original document platform cover on the same plane, the design of the printer 10 is improved.

[0046] Preferably, the upper surface 17s of the supply channel cover 17 at the first position P1 and the upper surface 15s of the original document cover 15 at the contact position CP are located on the same surface.

[0047] By placing the upper surface 17s of the supply channel cover and the upper surface 15s of the original document tray cover on the same plane, the design of the printer 10 is improved.

[0048] Figure 5 as well as Figure 6 The outline structure of printer 10 is shown. Figure 5 and Figure 6 The printer 10 is shown when the user puts the image reading unit 13 into an open state OS. Figure 5 A perspective view of the printer 10 with the image reading unit 13 in the open state, viewed from the front. Figure 6 This is a perspective view of the printer 10 with the image reading unit 13 in the open OS state, as observed from the rear. When the image reading unit 13 is in the open OS state, the user can approach the interior of the printer housing 11.

[0049] Figure 5 The interior of the printer housing 11 is shown in summary. An ink holding section 21 and the like are housed inside the printer housing 11. As an example, when the image reading unit 13 is in the open state (OS), a user can approach the ink holding section 21.

[0050] The ink holding section 21 holds one or more types of ink. In the case where the printer 10 is a cartridge-based ink refill structure, the ink holding section 21 holds one or more ink cartridges. The user can replace the ink cartridge when the image reading unit 13 is in the open state (OS). In the case where the printer 10 is a CISS (Continuous Ink Supply System) type ink refill structure, the ink holding section 21 holds one or more ink containers. The user can supply ink to the ink containers when the image reading unit 13 is in the open state (OS).

[0051] When the image reading unit 13 is in the open state OS, the supply channel cover 17 moves in conjunction with the image reading unit 13 from the first position P1 to the second position P2. When the user changes the image reading unit 13 from the obscured position CS to the open state OS, the supply channel cover 17 moves from the first position P1 to the second position P2. Figure 5 and Figure 6 As shown, when the image reading unit 13 is in the open state OS, the supply channel cover 17 is in the second position P2. The mechanism by which the image reading unit 13 moves the supply channel cover 17 will be described later.

[0052] Figure 7 The outline structure of printer 10 is shown. Figure 7 The printer 10 is shown when the user moves the supply channel cover 17 to the second position P2. Figure 7 A perspective view of the printer 10 with the supply channel cover 17 in the second position P2, viewed from the front.

[0053] The supply channel cover 17 is opened and closed by user operation. The supply channel cover 17 moves from the first position P1 to the second position P2 or from the second position P2 back to the first position P1 by user operation. When the user moves the supply channel cover 17 to the second position P2, the medium can be placed at the supply port 51. When the medium is placed at the supply port 51, the supply channel cover 17 functions as a guide member supporting the medium. When the original document stage cover 15 is in the contact position CP and the image reading unit 13 is in the shielded state CS, the supply channel cover 17 can move from the first position P1 to the second position P2.

[0054] Figure 8 as well as Figure 9 The outline structure of printer 10 is shown. Figure 8 and Figure 9 The printer 10 is shown when the user moves the original document tray 15 to the separation position SP. Figure 8 A perspective view of the printer 10 with the original document tray 15 in the separated position SP, viewed from the front. Figure 9A perspective view of the printer 10 with the original document tray 15 in the separated position SP, viewed from the rear.

[0055] Figure 8 The original document stage 23, the image reading unit frame 27, and the original document stage cover support 28 are shown. The image reading unit 13 includes the original document stage 23, the image reading unit frame 27, and the original document stage cover support 28.

[0056] The original document stage 23 holds the original document. The original document stage 23 corresponds to an example of an original document mounting stage. As an example, the original document stage 23 is constructed of glass that allows light to pass through. The original document stage 23 is either shielded or opened by the original document stage cover 15. When the original document stage cover 15 is moved to the separation position SP, the user can place the original document on the original document stage 23. The original document placed on the original document stage 23 is read by a sensor unit (not shown). The original document stage 23 is supported on the image reading unit housing 27.

[0057] The sensor unit reads the original document placed on the document stage 23 and generates readout data. As an example, the sensor unit is constructed from a CISM (Contact Image Sensor Module). The CISM includes a substrate, an LED (Light Emitting Diode) array, a lens array, etc. The sensor unit is positioned at a position in the -Z direction of the document stage 23. The sensor unit is configured to be movable along the document stage 23. The sensor unit reads the original document via the document stage 23.

[0058] The image reading unit frame 27 supports the document stage 23, sensor unit, etc. The image reading unit frame 27 corresponds to an example of a scanner housing. The image reading unit frame 27 is positioned at the outer periphery of the document stage 23 and surrounds the document stage 23. The detailed structure of the image reading unit frame 27 will be described later.

[0059] The original document stage support 28 is mounted on the original document stage 15 in a manner that allows it to rotate relative to the image reading unit 13. The original document stage support 28 is provided on the image reading unit housing 27. The original document stage support 28 is constructed of hinges or the like. As an example, the original document stage support 28 is mounted on the original document stage 15 in a detachable manner via a snap-fit ​​mechanism. Although... Figure 8 Two original document stage support portions 28 are shown, but the model is not limited to this. The image reading unit 13 has more than one original document stage support portion 28.

[0060] The document stage cover 15 is opened and closed by the user. The document stage cover 15 can be moved from the contact position CP to the separation position SP or from the separation position SP to the contact position CP by the user. When the user moves the document stage cover 15 to the separation position SP, the original document can be placed on the document stage 23. When the supply channel cover 17 is in the first position P1 and the image reading unit 13 is in the shielded state CS, the document stage cover 15 can move from the contact position CP to the separation position SP.

[0061] Figure 10 as well as Figure 11 The outline structure of printer 10 is shown. Figure 10 and Figure 11 The printer 10 is shown when the image reading unit 13 is turned into the open state OS by the user with the original document tray 15 in the separated position SP. Figure 10 A perspective view of the printer 10 when the user turns the image reading unit 13 into the open state OS, viewed from the front. Figure 11 A perspective view of the printer 10 when the user turns the image reading unit 13 into the open state OS, viewed from the rear.

[0062] The user can change the image reading unit 13 from the obscured state CS to the open state OS when the original document stage cover 15 is in the separated position SP. The image reading unit 13 will change to the obscured state CS or the open state OS according to the user's operation, regardless of the position of the original document stage cover 15. When the image reading unit 13 changes from the obscured state CS to the open state OS, the supply channel cover 17 will move from the first position P1 to the second position P2, regardless of the position of the original document stage cover 15.

[0063] Figure 10 and Figure 11 The document stage cover 15 at the separation position SP shown is not in contact with the supply channel cover 17. The separation position SP of the document stage cover 15 may vary depending on the structure of the document stage cover support 28, the user's operating method of the image reading unit 13, etc. When the separation position SP of the document stage cover 15 changes, the supply channel cover 17 at the second position P2 contacts the document stage cover 15 and supports the document stage cover 15. The supply channel cover 17 is positioned so that it can abut against the document stage cover 15 at the second position P2. By supporting the document stage cover 15 with the supply channel cover 17, it is possible to prevent the document stage cover 15 from rotating to an extent beyond what is expected. When the document stage cover 15 is mounted on the image reading unit 13 by a snap-fit, the supply channel cover 17 can prevent the document stage cover 15 from detaching from the image reading unit 13.

[0064] When the image reading unit 13 is in the open state OS and the original document stage cover 15 is in the separated position SP, preferably, the supply channel cover 17 of the first position P1 can abut against the original document stage cover 15.

[0065] By supporting the manuscript stage cover 15 with the supply channel cover 17, it is possible to prevent the manuscript stage cover 15 from rotating to an extent that is not expected.

[0066] Figure 12 The cross-sectional structure of printer 10 is shown. Figure 12 It shows Figure 3 The AA section is shown. Figure 12 The printer housing 11, the original document tray cover 15, and the supply channel cover 17 are shown in cross-section. Figure 12 The internal structure of the printer housing 11 is shown. The printer housing 11 houses the transport section 30 and the recording section 60.

[0067] The transport unit 30 transports media within the printer housing 11. The transport unit 30 includes a first transport path 31, a second transport path 33, a cartridge 35, and a paper discharge tray 37.

[0068] A first transport path 31 is disposed within the printer housing 11. The first transport path 31 is the path that transports the media from the cartridge 35 to the paper discharge tray 37. Along the first transport path 31 are arranged a pickup roller 41, a flip roller 42, a plurality of driven rollers 43, a transport roller pair 44, a media guide component 45, and a discharge roller pair 46.

[0069] The pickup roller 41 picks up the medium placed on the cartridge 35 and guides the medium onto the first transport path 31. The pickup roller 41 is positioned in the +Z direction of the cartridge 35. The pickup roller 41 is configured to rotate about the pickup roller rotation axis 41a. By rotating about the pickup roller rotation axis 41a, the pickup roller 41 contacts or separates from the medium placed on the cartridge 35.

[0070] The flip roller 42 conveys the medium, which is fed into the first conveying path 31 by the pick-up roller 41, toward the conveying roller pair 44. When the printer 10 performs double-sided printing on the medium, the flip roller 42 flips the medium, which is fed from the conveying roller pair 44 toward the flip roller 42, and then conveys it toward the conveying roller pair 44 again.

[0071] Multiple driven rollers 43 are arranged along the circumferential surface of the tilting roller 42. Each driven roller 43, together with the tilting roller 42, clamps and conveys the medium. The driven rollers 43 rotate drivenly as the tilting roller 42 rotates. Although Figure 12 Three driven rollers 43 are shown, but this is not the only possibility. The number of driven rollers 43 is set appropriately.

[0072] The conveyor roller pair 44 conveys the medium toward the medium guiding component 45 or the tilting roller 42. The conveyor roller pair 44 conveys the medium moving along the first conveying path 31 and the second conveying path 33. The conveyor roller pair 44 clamps the medium and transmits driving force. The conveyor roller pair 44 conveys the medium by transmitting driving force.

[0073] The media guiding member 45 supports the media conveyed by the transport rollers 44. The media guiding member 45 is positioned opposite the recording unit 60. The media guiding member 45 is positioned in the -Z direction of the recording unit 60. The media supported by the media guiding member 45 is printed through the recording head 62 of the recording unit 60. The recording head 62 will be described later.

[0074] The discharge roller pair 46 conveys the media printed by the recording unit 60 toward the paper discharge tray 37. The discharge roller pair 46 clamps the media and transmits driving force. The discharge roller pair 46 conveys the media by transmitting driving force. The discharge roller pair 46 is positioned in the +Y direction of the media guiding member 45.

[0075] A second transport path 33 is disposed within the printer housing 11. The second transport path 33 is a path from the supply port 51 to the transport roller pair 44. The medium transported on the second transport path 33 is transported to the printing position P opposite the recording head 62 via the transport roller pair 44. The second transport path 33 corresponds to an example of a transport path.

[0076] Supply port 51 is an opening for the supplied medium. Supply port 51 corresponds to an example of a media supply port. Supply port 51 is formed on the printer housing 11. Supply port 51 is located in the -Y and +Z directions of the printer 10. One or more sheets of media are placed at supply port 51. Supply port 51 is opened and closed by supply channel cover 17. When supply channel cover 17 is open, the user can place media at supply port 51.

[0077] The cartridge 35 holds the media. The cartridge 35 is positioned in the -Z direction of the printer 10. The cartridge 35 is configured to slide along the Y-axis via user operation. When the cartridge 35 moves in the +Y direction, the user can place the media onto the cartridge 35. When the cartridge 35 moves in the -Y direction, the media held in the cartridge 35 can contact the pickup roller 41.

[0078] The paper tray 37 holds the printed media after it has passed through the recording head 62. The paper tray 37 is configured to switch between a retracted state and an extended state. The retracted state is when the paper tray 37 is retracted into the printer housing 11. The extended state is when the paper tray 37 moves in the +Y direction and moves outside the printer housing 11. Figure 12The paper tray 37 is shown in its stowed state.

[0079] The recording unit 60 prints onto the medium. The recording unit 60 is positioned in the +Z direction of the medium guiding member 45. The recording unit 60 includes a carriage 61 and a recording head 62.

[0080] The carriage 61 supports the ink holding section 21 and the recording head 62, and moves the recording head 62 along the X-axis. The carriage 61 moves the recording head 62 along the X-axis in the +X or -X direction. The carriage 61 moves the recording head 62 on the medium supported by the medium guiding member 45.

[0081] The recording head 62 prints on the medium by ejecting ink. The recording head 62 corresponds to one example of a printing head. The recording head 62 ejects ink held in the ink holding section 21 onto the medium. The recording head 62 prints on the medium by ejecting ink onto the medium supported at a printing position P opposite to the recording head 62. The medium supported at the printing position P is transported on a first transport path 31 or a second transport path 33. The printing position P corresponds to one example of an opposite position.

[0082] Figure 13 The cross-sectional structure of printer 10 is shown. Figure 13 It shows Figure 3 The BB section is shown. Figure 13 The printer housing 11, the original document tray cover 15, and the supply channel cover 17 are shown in cross-section. Figure 13 The image reading unit 13 in the occluded state CS is shown. Figure 13 The original document stage cover 15 at the contact position CP is shown. Figure 13 The supply channel cover 17 at the first position P1 is shown. Figure 13 The internal structure of the printer housing 11 and the internal structure of the image reading unit 13 are shown.

[0083] Figure 14 The cross-sectional structure of printer 10 is shown. Figure 14 It shows Figure 3 The BB section is shown. Figure 14 Enlarged display Figure 13 Near the supply channel cover 17 shown. Figure 14 The image reading unit 13 in the occluded state CS is shown. Figure 14 The original document stage cover 15 at the contact position CP is shown. Figure 14 The upper surface 13s of the image reading unit, the original document stage cover side end 15a, and the supply channel cover side end 17a are shown. Figure 14 The supply channel cover 17 at the first position P1 is shown. Figure 14The image reading unit rotation axis 13R, the original document stage cover rotation axis 15R, and the supply channel cover rotation axis 17R are shown. Figure 14 The image reading unit rotation axis 13R and the supply channel cover rotation axis 17R are shown hypothetically.

[0084] The upper surface 13s of the image reading unit is the surface of the image reading unit 13 in the +Z direction. The upper surface 13s of the image reading unit corresponds to an example of the upper surface of the scanner unit. When the supply channel cover 17 is in the first position P1, a portion of the supply channel cover 17 overlaps with the upper surface 13s of the image reading unit. By the overlap of a portion of the supply channel cover 17 with the upper surface 13s of the image reading unit, the supply channel cover 17 opens and closes according to the displacement of the image reading unit 13.

[0085] The document stage cover side end 15a is the end face of the document stage cover 15 in the -Y direction. The document stage cover side end 15a corresponds to an example of the document stage cover end. The document stage cover side end 15a is opposite to the supply channel cover side end 17a. As an example, such as... Figure 14 As shown, the end 15a of the original manuscript platform cover is composed of an inclined surface.

[0086] The supply channel cover side end 17a is the end face of the supply channel cover 17 in the +Y direction. The supply channel cover side end 17a corresponds to an example of the supply mask end. The supply channel cover side end 17a is opposite to the original document stage cover side end 15a. As an example, such as... Figure 14 As shown, the supply channel cover side end 17a is formed by an inclined surface. The supply channel cover side end 17a is disposed at a position that overlaps with the original document platform cover side end 15a above the inclined surface.

[0087] The supply channel cover side end 17a of the supply channel cover 17 at the first position P1 and the original document platform cover side end 15a of the original document platform cover 15 at the contact position CP may or may not be connected to each other. Preferably, the supply channel cover side end 17a and the original document platform cover side end 15a are connected to each other. By connecting the supply channel cover side end 17a and the original document platform cover side end 15a, it becomes difficult for foreign objects such as dust to enter between the supply channel cover 17 and the original document platform cover 15.

[0088] Preferably, the supply channel cover side end 17a in the +Y direction of the supply channel cover 17 at the first position P1 is connected to the original document stage cover side end 15a in the -Y direction of the original document stage cover 15 at the contact position CP.

[0089] This makes it difficult for foreign objects such as dust to enter between the supply channel cover 17 and the original document table cover 15.

[0090] The image reading unit rotation axis 13R is the rotation center of the image reading unit 13. The image reading unit rotation axis 13R corresponds to an example of a first rotation axis. The image reading unit rotation axis 13R extends along an X-axis that intersects the Y-axis along the -Y direction. The X-axis corresponds to an example of an intersecting axis. The image reading unit 13 rotates around the image reading unit rotation axis 13R, thereby changing between a shielded state CS and an open state OS relative to the printer housing 11. A portion of the image reading unit 13 is positioned in the -Z direction of the supply channel cover 17. The image reading unit rotation axis 13R is positioned in the -Z direction of the supply channel cover 17.

[0091] The original document stage cover rotation axis 15R is the rotation center of the original document stage cover 15. The original document stage cover rotation axis 15R corresponds to an example of a third rotation axis. The original document stage cover rotation axis 15R extends along the X-axis, which intersects the Y-axis along the -Y direction. The original document stage cover 15 rotates around the original document stage cover rotation axis 15R, thereby rotating relative to the image reading unit 13 to the contact position CP and the separation position SP. The original document stage cover rotation axis 15R is positioned in the +Y direction of the image reading unit rotation axis 13R. The +Y direction corresponds to an example of a second direction. The original document stage cover 15 can be opened and closed without being affected by the state of the image reading unit 13.

[0092] The supply channel cover rotation axis 17R is the rotation center of the supply channel cover 17. The supply channel cover rotation axis 17R corresponds to an example of a second rotation axis. The supply channel cover rotation axis 17R extends along an X-axis that intersects the Y-axis along the -Y direction. The supply channel cover 17 rotates about the supply channel cover rotation axis 17R, thereby rotating relative to the supply port 51 to a first position P1 and a second position P2. The supply channel cover rotation axis 17R is positioned in the -Y and -Z directions of the image reading unit rotation axis 13R.

[0093] The image reading unit 13 includes a document stage cover 15 that can rotate about a document stage cover rotation axis 15R to a contact position CP covering the document stage 23 and a separation position SP opening the document stage 23. The document stage cover rotation axis 15R extends along the X-axis and is located in the +Y direction, which is opposite to the -Y direction of the image reading unit rotation axis 13R. When viewed from above in the +Z direction, the supply channel cover 17 is positioned in the -Y direction of the document stage cover 15.

[0094] Users can open and close the original document stage cover 15 without opening or closing the image reading unit 13 and the supply channel cover 17.

[0095] Figure 15 The outline structure of printer 10 is shown. Figure 15The printer 10 is shown in a top-down view from the +Z direction. Figure 15 The printer 10 is shown with the supply channel cover 17 removed. Figure 15 The image reading unit 13 in the occluded state CS is shown. Figure 15 The original document stage cover 15 at the contact position CP is shown. When the supply channel cover 17 is removed, the supply port 51 is exposed, so that the supply port 51 can be visually confirmed when viewed from above in the +Z direction.

[0096] The supply port 51 extends along the X-axis. A portion of the image reading unit 13 is disposed at positions in the +X and -X directions of the supply port 51. The supply port 51 is positioned within the frame of the image reading unit 13.

[0097] Figure 16 The outline structure of printer 10 is shown. Figure 16 The printer 10 is shown in a top-down view from the +Z direction. Figure 16 The printer 10 is shown with the original document tray cover 15 and the supply channel cover 17 removed. Figure 16 The image reading unit 13 in the occluded state of CS is shown. When the original stage cover 15 and the supply channel cover 17 are removed, the original stage 23 and the supply port 51 are exposed. The original stage 23 and the supply port 51 can be visually confirmed when viewed from above in the +Z direction.

[0098] The document tray 23 and the feed port 51 are configured along the Y-axis. The feed port 51 is located at a position in the -Y direction of the document tray 23. The width of the feed port 51 along the X-axis is shorter than the width of the document tray 23 along the X-axis.

[0099] Figure 17 and Figure 18 The outline structure of printer 10 is shown. Figure 17 and Figure 18 The printer 10 is shown with the original document tray cover 15 removed. Figure 17 and Figure 18 The image reading unit 13 in the occluded state CS is shown. Figure 17 and Figure 18 The supply channel cover 17 at the first position P1 is shown. When the original document stage cover 15 is removed, the original document stage 23 is exposed. The original document stage 23 can be visually confirmed when viewed from above in the +Z direction. Figure 17 The printer 10 is shown in a top-down view from the +Z direction. Figure 18 A perspective view of printer 10 as seen from the front is shown.

[0100] like Figure 16 , Figure 17 as well as Figure 18As shown, the supply channel cover 17 covers a portion of the image reading unit 13. The portion of the image reading unit 13 at the +X direction position of the supply port 51 and the portion of the image reading unit 13 at the -X direction position of the supply port 51 are covered by the supply channel cover 17.

[0101] Figure 19 The schematic structure of the image reading unit support substrate 29 is shown. Figure 19 The image reading unit support substrate 29 is shown in a perspective view from the +Z direction. The image reading unit support substrate 29 is one of the components constituting the image reading unit frame 27. The image reading unit frame 27 includes the image reading unit support substrate 29. The image reading unit support substrate 29 has a first frame component 29a, a second frame component 29b, a third frame component 29c, and a fourth frame component 29d.

[0102] The first frame component 29a is positioned in the +X direction of the image reading unit support substrate 29. The first frame component 29a extends along the Y-axis. The first frame component 29a is connected to the second frame component 29b and the fourth frame component 29d.

[0103] The second frame component 29b is positioned in the -Y direction of the image reading unit support substrate 29. The second frame component 29b extends along the X-axis. The second frame component 29b is connected to the first frame component 29a and the third frame component 29c.

[0104] The third frame component 29c is positioned in the -X direction of the image reading unit support substrate 29. The third frame component 29c extends along the Y-axis. The third frame component 29c is configured to be parallel or substantially parallel to the first frame component 29a. The third frame component 29c is connected to the second frame component 29b and the fourth frame component 29d.

[0105] The fourth frame component 29d is positioned in the +Y direction of the image reading unit support substrate 29. The fourth frame component 29d extends along the X-axis. The fourth frame component 29d is positioned parallel or substantially parallel to the second frame component 29b. The fourth frame component 29d is connected to the first frame component 29a and the third frame component 29c.

[0106] Figure 20 and Figure 21 The schematic structure of the image reading unit support substrate 29 is shown. Figure 20 and Figure 21 A portion of the image reading unit support substrate 29 is shown in magnified view. Figure 20 and Figure 21 The enlarged view shows the end of the third frame component 29c in the -Y direction. Figure 20The end of the third frame component 29c in the -Y direction is shown in a perspective view from the +Z direction. Figure 21 The end of the third frame component 29c in the -Y direction is shown in a view taken from the +X direction. Although in Figure 20 and Figure 21 Although not shown in the figure, the end of the first frame component 29a in the Y direction can have the same structure as the end of the third frame component 29c in the Y direction, or it can have a different structure.

[0107] A pressing portion 29p is provided at the end of the third frame component 29c in the -Y direction. The pressing portion 29p presses against the supply channel cover 17. The pressing portion 29p corresponds to an example of an abutment portion. The pressing portion 29p is provided in the image reading unit 13, which has an image reading unit frame 27 including an image reading unit support substrate 29. The pressing portion 29p can be integrally formed with the image reading unit frame 27 or separately formed. Preferably, the pressing portion 29p is integrally formed with the image reading unit frame 27. By integrally forming the pressing portion 29p with the image reading unit frame 27, the occurrence of malfunctions in the rotation of the supply channel cover 17 when the image reading unit 13 rotates is reduced.

[0108] Figure 22 , Figure 23 and Figure 24 The outline structure of the supply channel cover 17 is shown. Figure 23 and Figure 24 A portion of the supply channel cover 17 is shown in enlarged view. Figure 22 The supply channel cover 17 is shown in a perspective view from the -Z direction. Figure 23 A portion of the supply channel cover 17 is shown in a cross-sectional view viewed from the +X direction. Figure 24 A portion of the supply channel cover 17 is shown in a perspective view from the -Z direction.

[0109] A locking member 18 is provided on the supply channel cover 17. The locking member 18 corresponds to an example of the abutted portion. The locking member 18 abuts against the pressing portion 29p. By abutting against the pressing portion 29p with the locking member 18, the supply channel cover 17 is moved from a first position P1 to a second position P2. The locking member 18 has an abutment surface 18a, a locking surface 18b, and a bearing portion 18c.

[0110] The contact surface 18a is the surface that contacts the pressing part 29p. When the image reading unit 13 changes from the covered state CS to the open state OS through user operation, the pressing part 29p abuts against different positions on the contact surface 18a according to the change. The rotation position of the supply channel cover 17 changes according to the position of the pressing part 29p on the contact surface 18a.

[0111] The locking surface 18b is the surface that abuts against the image reading unit support substrate 29. The locking surface 18b restricts the rotation of the image reading unit 13 by abutting against the image reading unit support substrate 29. When the locking surface 18b abuts against the image reading unit support substrate 29, the image reading unit 13 stops in the open state OS.

[0112] The bearing 18c provides shaft support for the supply channel cover rotation shaft 17R. The engaging member 18 rotates around the supply channel cover rotation shaft 17R, which is supported by the bearing 18c. By rotating the engaging member 18, the supply channel cover 17, on which the engaging member 18 is provided, rotates around the supply channel cover rotation shaft 17R.

[0113] The engaging member 18 can be integrally formed with the supply channel cover 17 or it can be separately constructed. Preferably, the engaging member 18 is integrally formed with the supply channel cover 17. By making the engaging member 18 integrally formed with the supply channel cover 17, the occurrence of poor rotation of the supply channel cover 17 when it rotates is reduced.

[0114] The image reading unit 13 has an image reading unit frame 27 that supports the original document stage 23. Preferably, the pressing part 29p is integrally formed with the image reading unit frame 27, and the engaging member 18 is integrally formed with the supply channel cover 17.

[0115] Therefore, it becomes less likely that the supply channel cover 17 will malfunction when either the image reading unit 13 or the supply channel cover 17 rotates.

[0116] Figure 25 , Figure 26 as well as Figure 27 The outline structure of printer 10 is shown. Figure 25 , Figure 26 and Figure 27 A magnified view shows the vicinity of the supply channel cover 17. Figure 25 , Figure 26 and Figure 27 The operation of the mechanism by which the image reading unit 13 moves the supply channel cover 17 is shown. Figure 25 , Figure 26 as well as Figure 27 The pressing part 29p and the vicinity of the engaging part 18 are shown in cross-sectional view.

[0117] Figure 25 The image reading unit 13 is shown in a shielded state CS and the supply channel cover 17 is in the first position P1 of the printer 10. Figure 25The original document stage cover 15 is shown in the separated position SP. When the image reading unit 13 is in the shielded state CS and the supply channel cover 17 is in the first position P1, the mechanism by which the image reading unit 13 moves the supply channel cover 17 does not operate. The pressing part 29p is located opposite the abutment surface 18a of the engaging member 18. The pressing part 29p does not press the abutment surface 18a.

[0118] Figure 26 The image reading unit 13 is shown transitioning from the masked state CS to the open state OS at the printer 10. Figure 26 The original document stage cover 15 is shown in the separation position SP.

[0119] During the period when the image reading unit 13 changes from the masked state CS to the open state OS, the pressing part 29p abuts against the contact surface 18a of the engaging member 18. Depending on the change of the image reading unit 13 from the masked state CS to the open state OS, the position of contact between the pressing part 29p and the contact surface 18a of the engaging member 18 changes. The position of contact between the pressing part 29p and the contact surface 18a of the engaging member 18 moves towards the locking surface 18b. Based on the movement of the position of contact between the pressing part 29p and the contact surface 18a of the engaging member 18, the supply channel cover 17 rotates about the supply channel cover rotation shaft 17R supported by the bearing part 18c. The supply channel cover 17 moves from the first position P1 towards the second position P2.

[0120] Figure 27 The image reading unit 13 is shown in the image reading unit 13 in the open state of the OS printer 10. Figure 27 The original document stage cover 15 is shown in the separation position SP.

[0121] When the image reading unit 13 is in the open state OS, the pressing part 29p does not abut against the engaging member 18. The locking surface 18b of the engaging member 18 abuts against the substrate surface 29s of the image reading unit support substrate 29. The substrate surface 29s is the +Z direction surface of the image reading unit support substrate 29 when the image reading unit 13 is in the shielded state CS. When the locking surface 18b abuts against the substrate surface 29s, the supply channel cover 17 is in the second position P2. When the locking surface 18b abuts against the substrate surface 29s, the engaging member 18 restricts the rotation of the image reading unit 13 and stops the image reading unit 13 in the open state OS. The image reading unit 13 stops in the open state OS. The printer 10 uses the pressing part 29p and the engaging member 18 to make the image reading unit 13 and the supply channel cover 17 rotate in conjunction. The printer 10 can make the image reading unit 13 and the supply channel cover 17 rotate in conjunction through a simple mechanism.

[0122] Figure 25 , Figure 26 and Figure 27 The original document stage cover 15 is shown in the separation position SP. The mechanism by which the image reading unit 13 moves the supply channel cover 17 is unaffected by the position of the original document stage cover 15. When the original document stage cover 15 is in the contact position CP, the image reading unit 13 and the supply channel cover 17 rotate in conjunction.

[0123] The printer 10 includes: a recording head 62 for printing on media; a printer housing 11 for housing the recording head 62; an image reading unit 13 having a document table 23 for holding the original document and capable of rotating about an image reading unit rotation axis 13R to a closed state CS and an open state OS of the printer housing 11; a second transport path 33 disposed within the printer housing 11 and transporting media from a supply port 51 formed on the printer housing 11 to a printing position P opposite the recording head 62; and a supply channel cover 17 capable of rotating relative to the printer housing 11 about a supply channel cover rotation axis 17R to a first position P1 where the supply port 51 is closed and a second position P2 where the supply port 51 is open. When viewed from above in the +Z direction, the supply port 51 is provided in the -Y direction of the document table 23. The image reading unit rotation axis 13R and the supply channel cover rotation axis 17R extend along an X-axis intersecting the -Y direction. The supply channel cover rotation axis 17R is located in the -Y direction of the image reading unit rotation axis 13R. When the image reading unit 13 is in the shielded state CS and the supply channel cover 17 is in the first position P1, a portion of the supply channel cover 17 overlaps with the upper surface 13s of the image reading unit. When the image reading unit 13 is changed from the shielded state CS to the open state OS, the supply channel cover 17 moves from the first position P1 to the second position P2 by abutting the pressing part 29p provided on the image reading unit 13 against the engaging member 18 provided on the supply channel cover 17.

[0124] The printer 10 can rotate the image reading unit 13 and the supply channel cover 17 in conjunction with a simple mechanism.
