Description

  The present invention relates to a recording apparatus including a recording unit that performs recording on a recording medium.

  2. Description of the Related Art Conventionally, as a type of recording apparatus, a recording unit for recording on a sheet as a recording medium is disposed inside a housing (housing), and ink as a recording liquid is recorded on a sheet that is also conveyed in the housing. 2. Related Art Inkjet printers that perform printing (recording) by ejecting from a portion are known. In such a printer, a multifunction machine including a rotating body such as a scanner unit rotatably supported with respect to the housing on the side opposite to the gravitational direction (upper side) of the housing has been put into practical use.

  In this type of recording apparatus, an opening that exposes the sheet conveyance area is provided in the casing, and maintenance such as jam processing is performed through which the sheet jammed during conveyance is taken out of the casing from the conveyance area. It is set as the structure which can perform.

  The maintenance opening is formed in a rectangular shape having a longitudinal direction in a direction intersecting with the paper transport direction, and a rotation shaft having the longitudinal direction as an axial direction is attached to one end side of the paper in the paper transport direction. It can be opened and closed by the rotation of the rotating body. Normally, the rotating body is closed by being locked to the casing by a locking mechanism provided in the casing. On the other hand, when performing maintenance such as jam processing, the rotating body is unlocked to release the casing. Rotate away from the body to open the maintenance opening.

  Then, the jammed paper is taken out of the housing by, for example, inserting a hand into the opening thus opened by a maintenance worker. Therefore, it is necessary to ensure that the maintenance opening is long enough for the operator to insert his / her hand and perform jam processing in the sheet conveyance direction. For this reason, conventionally, a lock mechanism is provided in a side edge portion of the casing that is in the direction intersecting the sheet conveyance direction, that is, one side in the longitudinal direction of the opening (see, for example, Patent Document 1).

  By the way, when the lock mechanism is provided at the side edge of the housing, for example, when the lock mechanism is provided at the side edge on one side in the longitudinal direction, the rotating body is disposed on the other side far from the lock position in the longitudinal direction. There is a risk that the lock can be easily released by lifting the end. Further, when the lock mechanism is provided on each side edge portion on both sides in the longitudinal direction of the opening, the length in the longitudinal direction of the housing is increased and the recording apparatus is enlarged. Further, when a lock mechanism is provided on one end side in the paper transport direction in the housing, the lock position is close to the rotation axis of the rotating body in the paper transport direction. For this reason, when the edge part of a rotary body is lifted on the opposite side (for example, front side of a housing | casing) in the conveyance direction of a sheet | seat, there exists a subject that a lock | rock is easy to remove | release. Therefore, it is effective to provide a lock mechanism at the side edge (for example, the front edge) opposite to the rotation axis in the sheet conveyance direction among the four side edges surrounding the opening in the housing.

  However, the side edge located on the downstream side in the sheet conveyance direction, such as the front edge of the housing, has a length (width) of the side edge in the sheet conveyance direction in order to enlarge the maintenance opening. Is formed short. Therefore, when a lock mechanism is provided at the front edge of the casing, the front edge where the lock mechanism is provided in the casing needs to protrude toward the inside of the opening in order to secure a space for providing the lock mechanism. There is. That is, it is necessary to project the opening edge on the front side (downstream side in the sheet transport direction) of the maintenance opening to the rear side. As a result, the portion of the opening for maintenance that protrudes toward the inside of the opening cannot have a length sufficient to perform jam processing in the transport direction, and it is difficult to perform jam processing through the opening. There is a risk of becoming.

  The actual situation is that a recording medium conveyance area and a recording unit for recording on the recording medium are disposed inside, and a casing provided with an opening exposing the recording medium conveyance area, In a recording apparatus including a rotating body that has a rotating shaft on one end side of the body and rotates so that the opening can be opened and closed, and a lock mechanism that locks the rotating body to the housing, the recording apparatus is generally common. .

  The present invention has been made in view of such circumstances, and an object thereof is to stably lock the rotating body and to easily take out a recording medium in the housing from the opening to the outside of the housing.

The image reading unit 13 is centered on a rotating shaft 13a provided on one end portion side of the apparatus main body 12 from a state positioned above the apparatus main body 12 as shown by a two-dot chain line in FIG. As shown by the solid line arrow in FIG.

  Further, the printer 11 moves the image reading unit after the sheet P accommodated in the sheet cassette 15 detachably mounted on the bottom of the apparatus main body 12 moves on the conveyance path of the sheet P formed in the apparatus main body 12. It is conveyed toward the opposite side (+ Y direction side) from one end side where the 13 rotation shafts 13a are provided. Printing (recording) on the paper P is performed in the middle of the conveyance, and the printed paper P is placed on the other end side that is the conveyance direction destination side, as indicated by a two-dot chain line in FIG. The paper is discharged to the paper discharge tray 16 provided.

  That is, the apparatus main body 12 is equipped with a liquid ejecting head 17 (see FIG. 5) that ejects ink on the lower surface side thereof, and a carriage 18 that detachably holds a cartridge 19 (see FIG. 5) that contains ink. It is provided so as to be movable in one direction along the plane of the paper P, which is a direction intersecting the transport direction of the paper P. The carriage 18 functions as a recording unit, and printing (recording) is performed by ejecting the ink supplied from the cartridge 19 from the liquid ejecting head 17 while moving on the transported paper P. For this reason, in the apparatus main body 12, the moving area of the carriage 18 that moves and the conveyance area of the paper P that is printed and conveyed to the paper discharge tray 16 are provided inside the apparatus main body 12 so as to intersect each other.

  In the present embodiment, the moving direction of the carriage 18 is also referred to as a main scanning direction (± X direction). The transport direction of the transported paper P is also referred to as a sub-scanning direction (+ Y direction). Further, the sub-scanning direction side is referred to as a front front (front side), and among the main scanning directions (± X directions), the right direction as viewed from the sub-scanning direction side is described as + X direction, and the left direction is described as −X direction. Sometimes.

  The image reading unit 13 lifts or pushes down the front side, which is the conveyance direction side, around a rotation shaft 13a provided on the rear side (-Y direction side) opposite to the conveyance direction of the paper P in the apparatus main body 12. It is possible to do. For this lifting, a handle portion 13T is recessed in the front side of the side surface (both left and right side surfaces) of the image reading unit 13. The user of the printer 11 can lift the image reading unit 13 by inserting his / her hand into the handle portion 13T for maintenance, for example.

  Further, in the printer 11 of the present embodiment, when the image reading unit 13 is a first rotating body, the automatic document supply unit 14 as a second rotating body that automatically supplies a reading document to the image reading unit 13. It has. The automatic document supply unit 14 is disposed so as to overlap the upper side of the image reading unit 13, and rotates around a rotation shaft 14a (see FIG. 2A) provided on the rear side of the automatic document supply unit 14. Thus, the image reading unit 13 is lifted by a handle portion 14T provided on the front side opposite to the rotating shaft 14a. By lifting the automatic document supply unit 14, the user can manually supply the read document to the image reading unit 13.

  As shown in FIG. 1A, the apparatus main body 12 is provided with an opening 50 through which the conveyance area of the paper P is exposed when the front side of the image reading unit 13 is lifted and rotated away from the apparatus main body 12. It has been. The opening 50 is a first housing 12A as a housing located on one end side (rear side) of the apparatus main body 12, and a housing located on the other end side (front side) opposite to the one end side. The second housing 12B. The first housing 12 </ b> A forms a first side edge 51 located on the rear side (one end side) among the four side edges surrounding the opening 50, and the second housing 12 </ b> B surrounds the opening 50. A second side edge 52 that faces the first side edge 51 and is located on the front side (the other end side) opposite to the one end is formed. In the present embodiment, the second housing 12B forms side edge portions 53 and 54 in the left-right direction located on both sides in the main scanning direction among the four side edge portions surrounding the opening 50.

  In addition, the apparatus main body 12 is provided with an input panel 20 on the other end side for inputting data related to the printing (recording) operation of the printer 11 above the paper discharge table 16. The input panel 20 is configured by a housing portion having an inclined surface 20a whose lower side protrudes more toward the paper discharge direction than the upper side. Operation members that are operated when performing printing, such as a display unit (for example, a liquid crystal display) 21 for displaying a menu screen or the like on the inclined surface 20a and an operation button 22 including a power button, are provided. Is easy to operate.

  Now, during the printing operation of the printer 11, a lock mechanism 40 (see FIG. 2) that locks the image reading unit 13 to the apparatus main body 12 so that the image reading unit 13 is maintained in a closed state that does not expose the opening 50 of the apparatus main body 12. (See (a)) is provided in the apparatus main body 12. Here, the lock mechanism 40 holds the locked body 30 protruding downward on the lower surface portion 13 b on the front end side of the housing of the image reading unit 13, thereby moving the image reading unit 13 to the upper side of the apparatus main body 12. It is configured to lock in an overlapping state.

  As shown in FIG. 1B, the locked body 30 includes a pair of line-symmetric bending ribs 31 extending from the lower surface portion 13b of the housing of the image reading unit 13, and a space between these bending ribs 31. It is formed by the side wall 32 to connect. The bending ribs 31 are provided in parallel with each other, and thereafter provided with first inclined portions 31A that increase in distance from each other as they move away from the lower surface portion 13b of the housing, and thereafter, as the distance from the lower surface portion 13b of the housing increases. The 2nd inclination part 31B from which a space | interval becomes narrow is provided. Therefore, the pair of bent ribs 31 have a shape in which the gap between the bent portions 33 formed between the first inclined portion 31A and the second inclined portion 31B is the widest.

  As shown in FIG. 2A, the device main body 12 is provided with a lock mechanism 40 whose rotation is restricted by insertion of the locked body 30 having such a pair of bent ribs 31 formed therein. 50 is provided in the second housing 12B located on the front side. That is, the rotation of the image reading unit 13 as a rotating body is restricted by the lock mechanism 40 provided in the second housing 12B of the apparatus main body 12 on the front side away from the rotary shaft 13a provided on the rear side. The second housing 12B is positioned closer to one end of the apparatus body 12 than the input panel 20, and the lock mechanism 40 is positioned between the input panel 20 and the second side edge 52. Further, the protruding amount of the lock mechanism 40 from the second housing 12B is set smaller than the maximum protruding amount of the input panel 20 from the second housing 12B.

  As shown in FIG. 2B, the locking mechanism 40 pushes each curved rib 41 in a direction in which the gap between the concave surfaces 41a and the lock frame body 42 provided with a pair of curved ribs 41 having opposed concave surfaces 41a are narrowed. A pair of compression springs 43 attached to the lock frame 42 as described above. The lock frame 42 is fixed to the second housing 12B by the fixing screw 49, whereby the lock mechanism 40 is attached to the second housing 12B. By inserting the locked body 30 of the image reading unit 13 into the lock mechanism 40, the image reading unit 13 is locked in the closed state in which the opening 50 is closed with respect to the apparatus main body 12.

  As shown in FIGS. 3A and 3B, when the image reading unit 13 is locked to the apparatus main body 12, the image reading unit 13 substantially overlaps the upper side of the apparatus main body 12. At this time, after the second inclined portion 31B of the pair of bending ribs 31 pushes and inserts between the curved ribs 41 of the locking mechanism 40, the bending portion 33 of the locked body 30 of the image reading unit 13 is locked by the locking mechanism 40. The curved rib 41 is positioned between the concave surfaces 41a. In this state, the curved rib 41 whose spacing of the concave surface 41a has been returned by the compression spring 43 contacts the first inclined portion 31A of the bent rib 31 of the locked body 30. For this reason, the to-be-locked body 30 inserted into the locking mechanism 40 is sandwiched between a pair of curved ribs 41 whose pair of bending ribs 31 are pressed by a compression spring 43, thereby causing a predetermined lifting force (hereinafter referred to as "locking force"). In the following description, the lock mechanism 40 is held in a state where the lock mechanism 40 cannot be removed.

  Therefore, when the locked body 30 comes out of the locking mechanism 40, the bent portion 33 of the locked body 30 spreads between the concave surfaces 41 a of the curved rib 41 against the pressing force of the compression spring 43. Therefore, by lifting the image reading unit 13 with a force capable of expanding the curved rib 41 against the pressing force of the compression spring 43, the image reading unit 13 can be rotated to expose the opening 50. .

  In other words, the lock mechanism 40 prevents the image reading unit 13 from being accidentally lifted from the apparatus body 12 when, for example, the automatic document supply unit 14 is lifted with respect to the image reading unit 13. That is, the lock mechanism 40 according to the present embodiment allows the automatic document supply unit 14 to read the image by appropriately setting the magnitude of the force necessary to widen the curved rib 41 by adjusting the pressing force of the compression spring 43, for example. When rotating with respect to the unit 13, there is provided a regulation function for regulating the image reading unit 13 to a closed state in which the opening 50 is closed.

  Now, as shown in FIG. 4, in the printer 11 of the present embodiment, of the four side edges that surround the opening 50, the part where the lock mechanism 40 is provided at the second side edge 52 of the second housing 12 </ b> B. Is formed as a protruding portion 52 </ b> A that protrudes toward the first housing 12 </ b> A than the other portion of the second side edge 52. Thus, by forming the protruding portion 52A in the second housing 12B, the lock mechanism 40 can be attached to the second side edge 52 of the second housing 12B. Then, in the first side edge 51 of the first housing 12A, a facing part 51A facing the projecting part 52A of the second side edge 52 to which the lock mechanism 40 is attached (provided) across the opening 50 is provided. The first side edge portion 51 is formed so as to be retracted to one end side (−Y direction side) of the apparatus main body 12 rather than the other portion.

  As a result, as shown by hatching in FIG. 4, the conveyance area of the paper P is exposed in the opening 50. That is, the exposed conveyance area has a bent shape that bends to the rear side (−Y direction side) on the right side (+ X side) of the conveyance area of the paper P in accordance with the edge shape of the opening 50. The lock mechanism 40 is provided so that at least a part thereof is located outside the conveyance region of the paper P. Note that the length in the main scanning direction (± X direction) of the conveyance area indicated by hatching in FIG. 4 is the maximum width of the paper P conveyed in the printer 11.

  As shown in FIG. 5, in the present embodiment, the concave portion 55 formed by the facing portion 51 </ b> A of the second side edge portion 52 that is retracted rearward from the other portions is the cartridge 19 mounted on the carriage 18. This is a space area in which the operator who performs the replacement can insert a hand or the like. That is, the position where the carriage 18 stops to replace the cartridge 19 held by the carriage 18 is such that the cartridge 19 held by the carriage 18 is provided with the lock mechanism 40 at the second side edge 52 of the second housing 12B. It overlaps at least a part of the protruding portion 52A formed in the main scanning direction (± X direction).

  In the present embodiment, as indicated by a two-dot chain line in FIG. 5, the four cartridges 19 are detachably held on the carriage 18 in a state where they are aligned in the main scanning direction (± X direction). Then, each of the held four cartridges 19 is in the main scanning direction (± X direction) with at least a part of the protruding portion 52A provided with the lock mechanism 40 at the second side edge 52 of the second housing 12B. overlapping. Therefore, when each cartridge 19 is provided with the detachable lever 19a that is displaced at the time of detachment, the detachable lever 19a is positioned in the concave portion 55 formed by the facing portion 51A of the second side edge 52, and the exchange trader The cartridge 19 can be replaced by displacing the detachable lever 19a in the concave portion 55.

Next, the operation of the printer 11 of this embodiment will be described.
As shown in FIG. 4, the printer 11 of the present embodiment restricts the rotation of the image reading unit 13 at a position away from the rotation shaft 13a by a lock mechanism 40 provided in the second housing 12B. In addition, the opening width LH in the transport direction (+ Y direction) of the opening 50 that exposes the transport region of the paper P is opposed to the protruding portion 52A of the second side edge 52 in the second housing 12B provided with the lock mechanism 40. Since the facing portion 51A of the first side edge portion 51 is retracted, the opening width LHa of the portion where the lock mechanism 40 is provided can be prevented from becoming narrow. Incidentally, in the present embodiment, the opening width LHa is wider than the opening width LH.

  Further, as shown in FIG. 2A, the lock mechanism 40 is positioned between the input panel 20 and the second side edge 52 (specifically, the protruding portion 52A). In the present embodiment, the rear side (−Y side) end of the input panel 20 protrudes upward from the lock mechanism 40. Therefore, for example, when the paper P in the apparatus main body 12 is taken out from the apparatus main body 12 through the opening 50, an object (for example, a tool or an operator's hand) used for the extraction hits the lock mechanism 40 to perform the lock function. So that the lock mechanism 40 can be protected by the input panel 20.

According to the above embodiment, the following effects can be obtained.
(1) While the rotation of the image reading unit 13 is restricted at a position away from the rotation shaft 13a, the opening width LH of the opening 50 that exposes the conveyance area of the paper P can be prevented from becoming narrow in the conveyance direction of the paper P. Accordingly, the image reading unit 13 can be stably locked, and the paper P in the apparatus main body 12 can be easily taken out of the apparatus main body 12 from the opening 50.

  (2) When the paper P in the apparatus main body 12 is taken out of the apparatus main body 12 through the opening 50, the paper P in the apparatus main body 12 is removed from the apparatus main body 12 through the opening 50 while protecting the lock mechanism 40. It can be easily taken out.

  (3) In the conveyance area of the paper P, the formation of irregularities on the first side edge 51 and the second side edge 52 of the opening 50 is suppressed. Therefore, the paper P in the apparatus main body 12 can be easily taken out from the apparatus main body 12 through the opening 50.

  (4) Since the carriage 18 is stopped at the retracted portion of the first side edge portion 51 of the first housing 12A, the opening 50 for taking out the paper P to the outside of the apparatus main body 12 without forming a separate opening in the apparatus main body 12 is used. Thus, the cartridge 19 can be replaced.

  (5) The lock mechanism 40 stably locks the image reading unit 13 to the apparatus main body 12 while appropriately restricting the rotation of the automatic document supply unit 14 according to the open / closed state of the image reading unit 13 that opens and closes the opening 50. can do.

In addition, you may change the said embodiment into another embodiment as follows.
In the above embodiment, the position where the carriage 18 stops to replace the cartridge 19 is not necessarily the same as the cartridge 19 held by the carriage 18, but the locking mechanism 40 is provided at the second side edge 52 of the second housing 12 </ b> B. The protruding portion 52A may not overlap with the main scanning direction. For example, when the position where the carriage 18 stops for exchanging the cartridge 19 is away from the conveyance area of the paper P in the main scanning direction, the retracting portion (opposing portion 51A) of the first side edge 51 is the carriage 18. It can be provided regardless of the stop position.

  In the above-described embodiment, the lock mechanism 40 does not necessarily have to be provided so that at least a part of the lock mechanism 40 is located outside the conveyance region of the paper P. In other words, the lock mechanism 40 may be provided so that the entire lock mechanism 40 is located within the area for transporting the paper P. An example of this modification will be described with reference to the drawings.

  As shown in FIG. 6, in the present modification, the lock mechanism 40 is provided in the second housing 12 </ b> B so as to be positioned approximately at the center of the main body 12 in the main scanning direction (± X direction). Accordingly, the second side edge 52 of the second housing 12B is formed with a protruding portion 52A that protrudes toward the first housing 12A in the vicinity of the center in the conveyance region of the paper P. The first side edge 51 of the first housing 12A is formed with a facing portion 51A having a retracted shape corresponding to the protruding shape of the protruding portion 52A.

  Accordingly, in the present modification, the opening 50 provided in the apparatus main body 12 has an uneven shape, but the opening width LH along the transport direction (+ Y direction) of the paper P extends over the entire main scanning direction of the transport region. For example, it is possible to easily take out the paper P that is set to be substantially constant from the opening 50 having the opening width LH substantially constant. Further, since the lock mechanism 40 locks the image reading unit 13 to the apparatus main body 12 at substantially the center in the main scanning direction (± X direction), the image reading unit 13 can be stably locked to the apparatus main body 12. Can do.

  In this modified example, when it is possible to detect that the paper P is in the jammed state, the carriage 18 may be configured to move to the end portion in the main scanning direction when the jammed state is detected. Good. In this way, a space for an operator to insert a hand or a tool into the opening 50 in order to perform the jam processing is widened, and the operator can easily perform the jam processing.

  Further, in this modification, even if the concave portion 55 is provided at the first side edge 51 of the first housing 12A at the position where the carriage 18 stops in order to replace the cartridge 19, as shown in FIG. Good. The concave portion 55 may be provided on the first side edge portion 51 of the first housing 12A because the opening width of the opening 50 widens.

  In the above embodiment, when the lock of the lock mechanism 40 is released and the image reading unit 13 is rotated to the open state in which the opening 50 is opened, when the lock mechanism 40 is the first lock mechanism 40A, the image reading unit 13 is automatically It is preferable to include a second lock mechanism 40B that restricts the rotation of the document supply unit 14. Then, when the image reading unit 13 is in a closed state in which the opening 50 is closed, the first lock mechanism 40A allows the second lock mechanism 40B to be unlocked and allows the automatic document supply unit 14 to rotate with respect to the image reading unit 13. It is preferable to have a regulation function. This modification will be described with reference to the drawings.

  As shown in FIG. 7A, the lock mechanism of the present modification includes an automatic document supply unit in addition to the first lock mechanism 40A that locks the image reading unit 13 (first rotating body) with respect to the apparatus main body 12. 14 (second rotating body) is provided with a second locking mechanism 40 </ b> B whose rotation is restricted (locked) in a state where the upper rotating body 14 overlaps the upper side of the image reading unit 13. In a state in which the lock of the second lock mechanism 40B is released and the automatic document supply unit 14 is rotatable as indicated by the solid line from the two-dot chain line in FIG. 7A, the first lock mechanism 40A is connected to the image reading unit 13. Keep locked.

  On the other hand, as shown in FIG. 7B, in the open state in which the lock of the first lock mechanism 40A is released and the image reading unit 13 rotates about the rotation shaft 13a to expose the opening 50, the second lock mechanism. 40B locks the automatic document supply unit 14 in a state in which the rotation with respect to the image reading unit 13 is restricted. Therefore, the automatic document supply unit 14 is regulated so as not to rotate carelessly with respect to the image reading unit 13.

  That is, in the lock mechanism of this modification, when the first lock mechanism 40A is in the locked state, the lock of the second lock mechanism 40B can be released, and the lock of the first lock mechanism 40A is released. In this case, the lock of the second lock mechanism 40B can be maintained.

  Such a configuration of the locking mechanism can be realized, for example, by setting the locking force of the second locking mechanism 40B to be smaller than the locking force of the first locking mechanism 40A. The second lock mechanism 40B can adopt the same structure as that of the above embodiment. Or you may employ | adopt the structure using attractive force, such as a magnet.

  Alternatively, the first lock mechanism 40 </ b> A may have a regulation function that operates the lock function of the second lock mechanism 40 </ b> B to regulate the rotation of the automatic document supply unit 14 with respect to the image reading unit 13. In this case, although detailed description is omitted here, the first lock mechanism 40A may be configured to include an interlocking mechanism that operates the lock function of the second lock mechanism 40B when the lock is released. .

  Of course, the first lock mechanism 40A (the lock mechanism 40) controls the rotation of the automatic document supply unit 14 with respect to the image reading unit 13 and the image when the automatic document supply unit 14 rotates with respect to the image reading unit 13. You may make it provide at least one control function with the control function which controls the reading unit 13 to the closed state which the opening 50 closed.

  In the above embodiment, the automatic document supply unit 14 as the second rotating body is not necessarily provided for the image reading unit 13. Alternatively, a cover member that covers the image reading surface of the image reading unit 13 may be provided as the second rotating body.

  In the above embodiment, the input panel 20 may not necessarily be provided on the other end side of the apparatus main body 12. Even if the input panel 20 is provided on the other end side of the apparatus body 12, the lock mechanism 40 does not necessarily have to be positioned between the input panel 20 and the second side edge 52.

  In the above embodiment, the liquid ejecting head 17 is not limited to a so-called serial head type that ejects ink by reciprocating together with the carriage 18 in a direction intersecting the transport direction (sub-scanning direction) of the paper P. That is, in the state in which the length size is an overall shape corresponding to the width size of the paper P, and the longitudinal direction is fixedly arranged so as to be along the width direction (main scanning direction) intersecting the sub-scanning direction, the longitudinal direction In other words, a so-called line head type may be used in which ink is ejected from a large number of nozzles provided so as to cover substantially the whole of the paper P toward the paper P.

  The supply source of the ink that is the liquid ejected from the liquid ejecting head 17 may be other than the so-called on-carrier type cartridge 19 that is mounted on the carriage 18. For example, a so-called off-carriage type ink container provided inside the apparatus main body 12 of the printer 11 and other than the carriage 18 may be used. Alternatively, a so-called external type ink container provided outside the apparatus main body 12 may be used. In this way, the ink capacity is increased when the ink container provided outside the carriage 18 is used, compared to the case where the ink capacity is limited because the cartridge is mounted on the carriage 18. As a result, more ink can be ejected.

  When supplying ink from an ink container provided outside the apparatus main body 12 to the liquid ejecting head 17 inside the apparatus main body 12, an ink supply tube for supplying ink is connected from the outside of the apparatus main body 12. Must be routed inside. Therefore, in this case, it is preferable to provide a hole or a notch through which the ink supply tube can be inserted in the apparatus main body 12. Alternatively, the apparatus main body 12 is provided with a restricting member such as a boss that prevents the rotating body such as the image reading unit 13 provided in the apparatus main body 12 so that the opening 50 can be opened and closed completely from the apparatus main body 12. The ink supply tube may be routed from the outside to the inside of the apparatus main body 12 through the gap formed by the member. In this way, it is possible to easily supply ink to the liquid ejecting head 17 using the ink flow path of the ink supply tube.

  In the above embodiment, the printer 11 may include a unit other than the image reading unit 13 as a rotating body. For example, a FAX device or a wired or wireless communication device may be provided as the rotating body.

  In the above embodiment, the printer 11 serving as a recording apparatus is a fluid other than ink (a liquid, a liquid obtained by dispersing or mixing functional material particles in a liquid, a fluid such as a gel, or a fluid. It may be a fluid ejecting apparatus that performs recording by ejecting or ejecting solids (including solids that can be ejected by flowing). For example, printing is performed by ejecting a liquid material containing a material such as an electrode material or a color material (pixel material) used for manufacturing a liquid crystal display, an EL (electroluminescence) display, and a surface emitting display in a dispersed or dissolved state. A liquid ejecting apparatus may be used. Also, a fluid injection device for injecting a fluid such as a gel (eg, physical gel), a powder injection device (eg, a toner jet type) for injecting a solid such as powder (particles) such as toner Printing device). The present invention can be applied to any one of these fluid ejecting apparatuses. In the present specification, the term “fluid” is a concept that does not include a fluid consisting only of gas. Examples of the fluid include liquid (inorganic solvent, organic solvent, solution, liquid resin, liquid metal (metal melt), etc. ), Liquids, fluids, powders (including granules and powders), and the like.
