Title: Liquid ejecting apparatus

Description:
BACKGROUND 
     1. Technical Field 
     The present invention relates to a liquid ejecting apparatus ejecting a liquid to a medium. 
     2. Related Art 
     In the related art, as a type of liquid ejecting apparatus, an ink jet printer has been known which performs a printing (recording) by ejecting an ink to a medium like a sheet from a liquid ejecting head. Then, in the printer, in order to continuously supply an ink to the liquid ejecting head in a stable manner when performing a relatively large amount of printing, a configuration is proposed in which the ink is supplied from an ink tank whose capacity of containing an ink is relatively large to an ink cartridge through an ink supply tube (for example, refer to Chinese Utility Model Registration No. 2,825,289). 
     In the printer having such a configuration, the liquid ejecting head is mounted on a carriage which is moveable in a scanning direction inside a main body housing. Then, the ink supply tubes extending from the ink tank provided outside the main body housing is inserted to a movement region of the carriage through an opening portion at the upper side of the main body housing to be connected to the ink cartridge mounted on the carriage. In this case, the ink supply tubes have the middle portion thereof in the longitudinal direction is fixed by a fixing member provided so as to cross an opening portion at the upper side of the main body housing, and accordingly a terminal portion of the ink supply tubes which is inserted to a movement region of the carriage is guided to the ink cartridge. 
     Incidentally, in the above-mentioned printer, since a fixing member as a dedicated member for fixing an ink supply tube is provided across an opening portion, there is a concern that the ink supply tubes fixed to the fixing member disturb a movement of a carriage. 
     SUMMARY 
     An advantage of some aspects of the invention is to provide a liquid ejecting apparatus which can inhibit a liquid supply tube from disturbing the movement of a carriage. 
     The invention can be realized in the following forms or application examples. 
     According to an aspect of the invention, there is provided a liquid ejecting apparatus, including a liquid ejecting head ejecting a liquid to a target, a housing unit where a carriage having the liquid ejecting head is moveably disposed and an opening portion exposing at least a portion of a movement region of the carriage is formed, a liquid containing unit positioned at the outer side of the movement region of the carriage in a state of containing the liquid, a liquid supply tube which is connected between the liquid containing unit and the liquid ejecting head and has a deformable moving unit performing a follow-up deformation along a movement of the carriage, a fixing portion fixing a portion of the liquid supply tube in a longitudinal direction to be relatively immovable with respect to the opening portion. The housing unit is configured to have a housing portion in which a tray accommodation unit, where a discharge tray receiving the target discharged from the inside of the housing unit is accommodated to be able to pull out, is formed to project to a discharge direction of the target, and a housing portion where an operation panel unit operated at a time of use has an inclined surface whose lower side further projects to the discharge direction side than the upper side at an upper position than the tray accommodation unit. The deformable moving unit is formed at a downstream portion serving as the liquid ejecting head side rather than the fixing portion in the liquid supply tube. 
     In this case, a portion of the liquid supply tube may be fixed to be relatively immovable with respect to an opening portion of the housing unit, so that it is possible to stably form the deformable moving unit performing a follow-up deformation along a movement of the carriage on between the opening portion and the liquid ejecting head. As a result, it is possible to inhibit the liquid supply tube from disturbing the movement of the carriage. 
     The above-mentioned liquid ejecting apparatus preferably further includes a feeding cassette unit provided in a state of projecting in the discharge direction with the housing portion, obtained by detachably containing a feeding cassette, which can contain the target, in the housing portion formed to project in a discharge direction of the target. 
     In this case, it is possible to inhibit the liquid ejecting apparatus from getting larger. 
     In the liquid ejecting apparatus, the fixing portion is preferably provided at a substantially central portion in a movement region of the carriage in a movement direction of the carriage. 
     In this case, since the deformable moving unit of the liquid supply tube has substantially the same tube length at both sides of a movement range of the carriage, the length of the liquid supply tube present between the fixing portion and the liquid ejecting head side may be inhibited to be the shortest. 
     The liquid ejecting apparatus preferably further includes a cover member rotatably supported by the housing unit and opening and closing the opening portion be included, and the fixing portion, in the housing unit, be provided on a side supporting the cover member with respect to the opening portion. 
     In this case, when the cover member opens the opening portion of the housing unit, a view field inside the opening portion is unlikely to be disturbed by the liquid supply tubes, so that it is relatively easy to identify the inner state through the opening portion. 
     In the liquid ejecting apparatus, it is preferable that a support member be further included which supports a portion of the liquid supply tube disposed in a state of projecting to the opening portion of the housing unit, and the fixing portion fix a portion supported by the support member in the liquid supply tube, and the support member be provided so as to be displaceable in a movement direction of the carriage. 
     In this case, by displacing the support member in a direction away from the substantially central position of the opening portion of the housing unit, a user may easily insert the finger to the movement region of the carriage through the opening portion of the housing unit. Therefore, even if the carriage is in the middle position of the movement region, for example, it is possible to relatively easily perform maintenance of the carriage or a processing of a jam of a target. 
     In the liquid ejecting apparatus, it is preferable that one end side of the support member in a longitudinal direction be attached to be rotatable with respect to the housing unit. 
     In this case, by rotating the support member with respect to the housing unit, it is possible to easily realize a configuration where the support member may be displaced in a direction away from the substantially central position of the opening portion of the housing unit. 
     In the liquid ejecting apparatus, it is preferable that, in the liquid supply tube, a plurality of tubes be connected to each other through a joint connecting between tubes. 
     In this case, by connecting a plurality of tubes, it is possible to adjust an optimal length to pull around the liquid supply tube. 
     In the liquid ejecting apparatus, it is preferable that the liquid supply tube be provided one or more than one. 
     In this case, using the liquid supply tube of the number corresponding to the number of the liquid containing unit, it is possible to provide a liquid from each liquid containing unit to the liquid ejecting head. 
     In the liquid ejecting apparatus, it is preferable that the liquid containing unit be positioned at the outer side of the housing unit. 
     In this case, restrictions on the containing amount of liquid are eased in the outer side of the housing unit, so that it is possible to include a liquid containing unit which may contain a relatively large amount of liquid. 
     In the liquid ejecting apparatus, the liquid containing unit positioned at the outer side of the housing unit in a state of containing the liquid ejected by the liquid ejecting head contains a black liquid. 
     In this case, the black liquid is consumed a lot, so that a capacity to contain the black liquid increases.

     DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     First Embodiment 
     Hereinafter, as a first embodiment of a liquid ejecting apparatus, an ink jet type printer is described referring to drawings, which includes a liquid ejecting head ejecting an ink as an example of liquid and prints an image including characters, graphics and the like by ejecting the ink to a sheet as an example of a target. 
     As illustrated in  FIG. 1 , a printer  11  of the present embodiment includes a printing function unit  12 A (printer unit) made of an apparatus main body  12  having a printing function, and an image reading unit  13  (scanner unit) having a scan function on the upper side of the apparatus main body  12 , and is so-called a multifunction machine. In the following description, the printer made of the multifunction machine is referred to as a printer  11 . 
     The printer  11  is provided with an ink through ink supply tubes  40  (refer to  FIG. 3 ) disposed by a fixing portion from an ink tank  19 T (refer to  FIG. 3 ) as an example of a liquid containing unit having a rectangular parallelepiped shape as a separate body. 
     In the printer  11 , a printing function unit  12 A as an example of a housing unit embedded with a printing unit  20  is disposed on a lower portion side which is the gravity direction thereof, and an image reading unit  13  as an example of a cover member embedded with an image reading mechanism such as a scanner and the like reading a manuscript (image) is disposed on the upper portion side which is a counter-gravity direction. The image reading unit  13  rotates (displaces) about a hinge  13   a  provided at one side end (rear side) of the apparatus main body  12 , and the hinge  13   a  is configured to have the front side of the opposite side lifting. That is, on a housing side surface (both left and right side surface) of the image reading unit  13 , a hand grip portion  13 T is provided to be concaved, and a user of the printer  11 , for example, may raise the image reading unit  13  by putting a hand in the hand grip portion  13 T during maintenance. By the raising, an opening portion  12 K (refer to  FIG. 3 ), exposing at least a portion of the movement region of the carriage  21  disposed so as to reciprocate in the printing function unit  12 A (that is, apparatus main body  12 ), is exposed. 
     Furthermore, an automatic manuscript supply device (auto document feeder) automatically providing a reading manuscript to the image reading unit  13  is disposed at the upper side of the image reading unit  13 . The automatic manuscript supply device  14  rotates about the hinge  14   a  (refer to  FIG. 2 ) provided at one side end (at rear side) of the apparatus main body  12  so that the hinge  14   a  has the front side of the opposite side lifting. By the lifting of the automatic manuscript supply device  14 , the manuscript stand  13   b  (refer to  FIG. 2 ) formed on the upper surface of the image reading unit  13  is exposed, so that a user may manually supply a read manuscript with respect to the image reading unit  13 . 
     Here, the automatic manuscript supply device  14  includes a manuscript tray  14   d  for setting a manuscript on the upper side of a main body  14   c  in a rectangular plate shape, and on the manuscript tray  14   d , a guide member  14   e  for positioning a document in the width direction is provided. The document set on the manuscript tray  14   d  is fed onto a document table  13   b  of the image reading unit  13  one by one by an operation of a feed mechanism unit  14   f  disposed on the left side in the  FIG. 1 , and discharged onto the main body  14   c  after reading the document image. 
     In addition, at the lower portion of the apparatus main body  12 , a sheet feeding cassette  15  which may contain a plurality of overlapped sheets P is detachably provided. A sheet P contained in the sheet feeding cassette  15  is fed one by one toward the front from the rear of the printing unit  20  provided in the printing function unit  12 A, and the printing unit  20  performs printing on the fed sheet P. That is, the sheet P fed from the sheet feeding cassette  15  is transported to the printing unit  20  by a transportation mechanism having rollers  24 ,  25 , and the like to be described below. In the printing unit  20 , an ink is ejected to the sheet P from a liquid ejecting head  22  reciprocating by a moving mechanism along a direction referred to as main scanning direction X) intersecting with the transportation direction (referred to as a sub-scanning direction Y) of the sheet P, and an image and the like are printed on the sheet P. The printed sheet P where printing is finished by the printing unit  20  is discharged (discharge paper) from a sheet discharge port  16  provided at the front surface of the apparatus main body  12  (printing function unit  12 A). 
     In the apparatus main body  12  (printing function unit  12 A), on the upper side of the sheet feeding cassette  15  and the lower side of the sheet discharge port  16 , a stacker  17  as an example of a discharge tray, which receives the sheet P discharged from the sheet discharge port  16 , is accommodated. The stacker  17  is used by the length being pulled out from the main body  12  corresponding to the size of the discharged sheet P. 
     A containing unit  12 S having a containing concave portion where the sheet feeding cassette  15  and the stacker  17  are contained at a center portion in a width direction is configured to have a housing portion formed to project to a discharge direction of the sheet P (here, a sub-scanning direction Y). Projecting the containing unit  12 S is because the length of the sheet feeding cassette  15  in a sub-scanning direction Y is longer than the length of the housing  12 H in the sub-scanning direction Y, which is needed in the printing unit  20 . Therefore, the sheet feeding cassette  15  and the stacker  17  are contained so as to align the front end surface to the containing unit  12 S in a state of projecting from the apparatus main body  12  in the sub-scanning direction Y (frontward). Specifically, when the length of the apparatus main body  12  in the sub-scanning direction Y is determined according to the length of the sheet feeding cassette  15  in the sub-scanning direction Y which is needed so as to contain the sheet P of a predetermined size (for example, A4), since the apparatus main body  12  gets larger (increase in the lower surface area), in order to avoid this even a little, only a containing unit part of the sheet feeding cassette  15  is allowed to project. In other words, by gouging out both sides of the containing unit  12 S containing the sheet feeding cassette  15 , a portion of the sheet feeding cassette  15  and the containing unit  12 S is allowed to project frontward. In addition, the front surface position during accommodating the stacker  17  according to the projecting front surface position of the sheet feeding cassette  15 , so that a projection length when pulling out the stacker  17  is ensured to be relatively long. Furthermore, by the projection, the stacker  17  is made to be easily pulled out from the apparatus main body  12  by a grip portion  17   a . Thus, the sheet feeding cassette  15  is detachably provided at the front surface of the apparatus main body  12 , compared to a configuration enabling the sheet to be supplied from the front surface side of the apparatus main body  12 , the printer  11  is relatively inhibited from getting larger (particularly, increase in the lower surface area of a printer). The containing unit  12 S configures a tray accommodation unit where the stacker  17  is contained to pull out. 
     On the other hand, as illustrated in  FIG. 1 , an operation panel unit  18  for performing various types of operations such as performing printing on the printing unit  20  is disposed at a position upper than the sheet discharge port  16  in the apparatus main body  12  (printing function unit  12 A). A base portion  12 B of an operation panel unit  18  is configured to include a housing portion having an inclined surface whose lower side further projects to a discharge direction (that is, the sub-scanning direction Y) of the sheet Y than the upper side. Then, on the inclined surface of the base portion  12 B, a display unit  18   a  for displaying a menu screen and the like (for example, liquid crystal display) and an operation button  18   b  are attached. In the operation button  18   b , for example, a power button, a selection button selecting a desired item from the menu screen, and a printing start button for instructing the start of the print are provided. The operation panel unit  18  is formed to be an inclined surface which projects to the front of the apparatus main body  12  and has a display surface and the operation surface descending forward, so that the visibility of the display unit  18   a  and operability of the operation button  18   b  is well ensured by a user. 
     Now, the printing unit  20  including the printer  11  according to the present embodiment includes a liquid ejecting head  22  which has a carriage  21  as an example of a moving body reciprocating in a main scanning direction X, and ejects an ink to the carriage  21 . The carriage  21  is guided by a guide frame  30  which is a plate member extending along the main scanning direction X, and disposed to be moveable (reciprocate) in the main scanning direction X. The guide frame  30  has an upper rail  31 A and a lower rail  31 B formed by a member bent in a substantially U-shape at both upper and lower side end portions of a plate member orthogonal to the main scanning direction X. The carriage  21  reciprocates in the main scanning direction X in a state where the rear end side is supported by the upper rail  31 A and the lower rail  31 B. Then, an ink provided through the ink supply tubes  40  from the ink tank  19 T (refer to  FIG. 3 ) is ejected from the liquid ejecting head  22  included in the reciprocating carriage  21 , thereby performing printing on the sheet P. 
     The carriage  21  has a substantially rectangular box shape whose upper part is open, and on a mounting portion in a concave shape on the upper portion, an adapter AD relaying an ink provided through the ink supply tubes  40  to the liquid ejecting head  22  is mounted. An ink is provided from the adapter AD mounted on the carriage  21  to the liquid ejecting head  22 . Therefore, the ink supply tubes  40  connected to the adapter AD forms a portion of an ink flow path in which an ink may flow between the ink tank  19 T and the liquid ejecting head  22 . 
     Color printing is available in the printer  11  of the present example, and in the adapter AD in an example of  FIG. 1 , a plurality of ink colors (for example, four) the same as the number of ink colors (for example, four) required in color printing are mounted. Of course, by mounting only a black color adapter AD, it is possible to use the printer  11  as a monochrome print-ready printer. In addition, the carriage  21  can be used with an ink cartridge mounted thereon, and the adapter AD has a rectangular plate shape adjusted to the shape and the size of the ink cartridge corresponding to the printer  11 . However, the ink volume is less than the ink cartridge, so that the shape and the size of the adapter AD may be appropriately changed within a range where the adapter AD may be mounted on a mounting portion of the carriage  21 . 
     In addition, as illustrated in  FIG. 1 , at the front surface left side end portion of the apparatus main body  12 , a slot  32  for inserting a card such as a memory card or a communication card, and a communication port  33  (connector) corresponding to a predetermined communication method, for example, USB communication and the like are provided. In the printer  11 , printing based on data received from the host device through USB communication, and photo printing performed by reading the image data such as photographs from the memory card are possible. 
       FIG. 2  illustrates the printer  11  in a state where an automatic manuscript supply device  14  is removed. In a state where the automatic manuscript supply device  14  is open, a manuscript stand  13   b  of the image reading unit  13  illustrated in  FIG. 2  is exposed, at a position lower than the reading surface (glass surface), a long reading head  13 H of a long shape in the sub-scanning direction Y is provided to be moveable in the main scanning direction X. At the bottom portion of the image reading unit  13 , a concave groove  13   c  where a flexible flat cable  13 F (hereinafter, referred to as ‘FFC  13 F’) connected to one end portion of the reading head  13 H is contained is formed so as to extend in the main scanning direction X. The FFC  13 F moves in the concave groove  13   c  to follow when the reading head  13 H moves in the main scanning direction, and accordingly the reading head  13 H may transmit a manuscript reading signal to a controller (not illustrated) in the printer  11  through the FFC  13 F in the entire region of the movement path. In addition, in the adjacent position of the manuscript stand  13   b  on the upper surface of the image reading unit  13 , a transporting surface  13   d  of the sheet fed from the automatic manuscript supply device  14  is formed. 
     In addition, as illustrated in  FIG. 2 , on a back surface side of the apparatus main body  12  (printing function unit  12 A), a manual sheet feeding mechanism  35  is embedded. The manual sheet feeding mechanism  35  is a mechanism feeding one sheet P manually set by a user. The manual sheet feeding mechanism  35  includes a sheet feeding tray  35   a  in a substantially rectangular plate shape, a pair of sheet guides  35   b  operated when positioning the sheet P on the sheet feeding tray  35   a  in the width direction, and a protective plate  35   c  provided on a purpose of preventing debris and the like from falling to a feeding port (not illustrated) in an opening state of the manual sheet feeding mechanism  35 . The sheet feeding tray  35   a  is provided to rotate about the base end portion in a predetermined angle range (a lower end portion in  FIG. 2 ), and disposed at an opening position illustrated in  FIG. 2  which has an inclined posture in which the sheet P may be set, and a closing position rotated from the opening position to the front side of  FIG. 2  and accommodated in the apparatus main body  12 . The protective plate  35   c  is biased to a direction accessing the sheet feeding tray  35   a  by an elastic force of the torsion coil spring (not illustrated), and when opening the sheet feeding tray  35   a , a lower portion region of the sheet feeding tray  35   a  is disposed at predetermined intervals (for example, 3 to 10 mm) and disposed at a protective position illustrated in  FIG. 2  preventing debris from entering the feeding port. 
     In addition, the stacker  17  includes a first tray  17   b , a second tray  17   c , and a third tray  17   d  in a three stage form, as an example. The first tray  17   b  is slidably connected with the apparatus main body  12 , and the second tray  17   c  is slidably connected with the first tray  17   b . Then, the third tray  17   d  is rotatably connected to a front end portion of the second tray  17   c , and disposed at a closing position where the third tray  17   d  is accommodated in a state of overlapping with respect to the second tray  17   c , and an opening position functioning as a stopper of the sheet before rising upward at a predetermined angle as illustrated in  FIG. 2 . 
     Next, a configuration of a printing unit  20  will be simply described using  FIG. 3 . As illustrated in  FIG. 3 , in the housing  12 H, at a position opposite to the lower surface (nozzle formation surface) of the liquid ejecting head  22  (refer to  FIG. 1 ) provided at the lower portion of the carriage  21 , a support stand  23  in a long shape extending along the main scanning direction X is disposed. At each position at upstream side and downstream side interposing the support stand  23  in the sub-scanning direction Y, a transportation roller  24  and a sheet discharge roller  25  are disposed. The sheet P contained in the sheet feeding cassette  15  is in contact with a pickup roller on the upper surface, which is not illustrated. The pickup roller rotates, and accordingly the most upper sheet among the sheet P is sent out in a path through the rear side, the sheet P sent out has the path inverted to the sub-scanning direction Y along the outer peripheral surface of the feeding roller (not illustrated), and thereafter when the sheet P reaches the transportation roller  24 , the sheet P is fed onto the support stand  23  by rotation of the transportation roller  24 . 
     In addition, in the housing  12 H, a timing belt  27  in an endless shape wound around the pair of pulley  26  is arranged along a guide frame  30  disposed on the back surface side of the carriage  21 , and the back surface portion of the carriage  21  is fixed to a portion of the timing belt  27 . At the lower side of the timing belt  27 , a linear encoder  28  extending in parallel to the timing belt  27  is provided, and a position of the carriage  21  is detected based on the detection signal. 
     When a carriage motor where the output shaft is connected to a pulley  26  and which is not illustrated is driven forwardly and reversely, the timing belt  27  rotates forwardly and reversely and the carriage  21  reciprocates in the main scanning direction X along rails  31 A and  31 B. Then, during movement of the carriage  21 , by alternately performing a recording operation ejecting an ink from the liquid ejecting head  22  and performing a recording of one row (one pass) on the sheet P and a transportation operation transporting the sheet P to a next recording position, documents, images, or the like are printed on the sheet P. At that time, according to a carriage position detected based on a detection signal of the linear encoder  28 , ejection or non-ejection of an ink for every nozzle of the liquid ejecting head  22  is controlled. 
     An ink used by the liquid ejecting head  22  in the printing is provided to the liquid ejecting head  22  through each ink supply tubes  40  and each adapter AD from each ink tank  19 T in an external tank unit  19 . In the tank unit  19  of the example, four ink tanks  19 T each containing four different color inks as an example are contained. As these four colors, for example, black (K), cyan (C), magenta (M), and yellow (Y) are mentioned. In an example of  FIG. 3 , among four ink tanks  19 T, one containing a black ink which has comparatively large ink consumption amount is a wide large tank, and three for color each containing three color inks are small narrow tanks. 
     In addition, in the adapter AD which is mountable on the carriage  21 , according to the shape and the size of an ink cartridge of a corresponding ink color, one for black ink is thick, and one for color ink has a thickness thinner than the one for black ink. When the carriage  21  has a plurality (four) of ink cartridge mounting concave portions, and the adapter AD is mounted on these mounting concave portions, a terminal of the back surface is in contact with a terminal of the carriage  21  side. 
     Next, the configuration of the first embodiment according to a fixing portion fixing the ink supply tubes  40  will be described referring to  FIGS. 3 to 5 . The fixing portion of the first embodiment has a configuration of fixing the ink supply tubes  40  using a fixing tool to the housing  12 H forming the opening portion  12 K. As the fixing tool, it is possible to use various members such as string, rubber bands, clips, adhesive tape, adhesive or the like. In addition, the present embodiment is described by using an adhesive tape as an example of the fixing tool. In addition, in description of  FIGS. 3 to 5 , configuration members the same as those in  FIG. 1  are given the same reference numbers, and the description is appropriately omitted. 
     As illustrated in  FIG. 3 , the ink tank  19 T is disposed at the outside of the movement region of the carriage  21 , and particularly disposed at the outside of the housing  12 H. The ink tank  19 T, when viewed from the front side of the printer  11  (the front side in the sub-scanning direction Y), is disposed at the left outside of the housing  12 H, that is, a position opposite to a home position in the main scanning direction X. Then, one end portion of the ink supply tubes is connected to the ink tank  19 T, and an opposite side portion of the ink supply tubes  40  is inserted in a movement region of the carriage  21  exposed through the opening portion  12 K provided in the housing  12 H from a position close to the home position in the main scanning direction X of the carriage  21 . The other inserted end portion is connected to the adapter AD mounted on the carriage  21 . Specifically, one end portion of the ink supply tubes  40  is connected to a discharge tube (not illustrated) provided in a state of being in communication with the ink tank  19 T at the lower portion of the tank unit  19 , and the other end portion is connected to a supply tube (not illustrated) on the upper surface of the adapter AD mounted on the carriage  21 . Each ink supply tube  40  connected between the tank unit  19  and the adapter AD on the carriage  21 , in a case where the hinge  13   a  side rotatably supporting the image reading unit  13  is set to the rear side, the upside of the rear side portion of the opening portion  12 K is built to be substantially straightly extended in the main scanning direction X. 
     As illustrated in  FIG. 3 , on the upper surface of the housing  12 H, so as to cross-cut the opening portion  12 K in the sub-scanning direction Y, a support plate  41  in an elongated plate shape is provided as an example of a support member. The length of the support plate  41  in a longitudinal direction is slightly longer than the width of the opening portion  12 K in the sub-scanning direction Y. On the upper surface portion  12 U of the housing  12 H, at a position corresponding to a locking projection  36  projected at a substantially central position of the inner surface front end portion of the image reading unit  13  in the width direction, a locking concave portion  12   d  to be locked with the locking projection  36  are provided to be concaved with the image reading unit  13  closed. One end portion of the support plate  41 , using a screw hole (not illustrated) formed to fix a locked member (not illustrated) to the lower surface of the locking concave portion  12   d , has a screw  43  slightly projecting from the upper surface of the housing  12 H to the screw hole or screwed in a hole of the end portion of the support plate  41 , and is rotatably supported around the screw  43 . Therefore, by rotating the support plate  41  in a surface parallel to the opening surface of the opening portion  12 K around the screw  43 , an angle formed between the longitudinal direction of the support plate  41  and the main scanning direction X is changeable, so that it is possible to adjust a fixed position of a portion of the ink supply tubes  40  on the support plate  41 . 
     Then, in a state where an angle of a position fixing a portion of the ink supply tubes  40  is adjusted, an end portion (free end) of the rotation front end side of the support plate  41  is fixed to the upper surface portion  12 U of the housing  12 H by the fixing tool  42 . The fixing tool  42  may be, for example, an adhesive tape. Of course, the fixing tool  42  may also be a screw, an adhesive or the like. At a position slightly apart from the left of the locking concave portion  12   d  on the upper surface portion  12 U of the apparatus main body  12 , a detected concave portion  38  is formed where the projection  37  provided on the inner surface is inserted when closing the image reading unit  13 . In addition, a ventilating port  47  is formed around the opening portion  12 K on the upper surface portion  12 U of the housing  12 H. 
     In addition, at a further rear position than the opening portion  12 K on the upper surface portion  12 U of the housing  12 H, at a position corresponding to a projection unit projecting at a point on the rear surface side corresponding to the concave groove  13   c  of the image reading unit  13 , a concave portion  12   b  where the projection unit is contained is formed. As illustrated in the embodiment, in a configuration of pulling the ink supply tubes  40  around the upper surface portion  12 U of the housing  12 H, it is desirable to route the ink supply tubes  40  avoiding the concave portion  12   b  where the projection unit is contained. 
     Moreover, on the upper surface of the housing  12 H, a boss  29  in a substantially cylindrical shape is fixed in a state of projecting upward at a predetermined length. That is, the boss  29 , when rotating the image reading unit  13  in a closing direction to close the opening portion  12 K, is interposed between the printing function unit  12 A and the image reading unit  13 , and accordingly, between the image reading unit  13  and the printing function unit  12 A, is provided so as to ensure a void through which the ink supply tubes  40  are inserted. In  FIG. 3 , in order to stably form the void, two bosses  29  are provided, but the boss  29  may be one. 
     The middle portion in the longitudinal direction of the ink supply tubes  40  inserted through the void formed by the boss  29  is fixed to the upper surface portion  12 U of the housing  12 H by a first fixing tool  61  (for example, adhesive tape). In the present embodiment, for example, it is described that the middle portion is fixed using a plurality of fixing tools (three adhesive tapes in  FIG. 3 ). Of course, a fixing tool is used as many as required to fix the ink supply tubes  40 . 
     Specifically, the ink supply tubes  40  first extends from the tank unit  19  where a plurality of ink tanks  19 T are contained in a tank case, and fixed to a portion disposed on the upper surface portion  12 U extending in the main scanning direction X from the left side surface slightly back side in  FIG. 3  of the apparatus main body  12  by the first fixing tool  61 . Next, the middle portion on the downstream side which is a connection side further to the adapter AD in the ink supply tubes  40  is sequentially fixed by a second fixing tool  62  and a third fixing tool  63  with respect to the support plate  41 . 
     In addition, as illustrated in  FIG. 3 , an adapter AD close portion in the ink supply tubes  40  is held in a state of being bundled by a holding member  44  fixed to a right side surface in  FIG. 3  of the carriage  21 , and an end portion on a further downstream side than a position bundled by the holding member  44  is connected to a supply tube (not illustrated) on the upper surface of the adapter AD, respectively. 
     The middle portion of the ink supply tubes  40  fixed by the first to the third fixing tools  61 ,  62 , and  63  is controlled to move in a length direction of the ink supply tubes  40  and a direction intersecting with the length direction. 
     Therefore, the first to the third fixing tools  61 ,  62 , and  63  fixing the middle portion of the ink supply tubes  40  function as an example of the fixing portion. 
     Then, in the embodiment, among the first to the third fixing tools  61 ,  62 , and  63 , the third fixing tool  63  (for example, adhesive tape) fixing the middle portion of the most downstream side with respect to the housing  12 H of the ink supply tubes  40  is a fixing portion fixing a portion of the ink supply tubes  40  in the length direction to be in a state where relative movement with respect to the opening portion  12 K is not possible. As a result, a portion between the third fixing tool  63  and the adapter AD in the length direction of the ink supply tubes  40 , more accurately, a portion between the third fixing tool  63  and the holding member  44  is a deformable moving unit  40 H deformed according to a movement of the carriage  21  as illustrated in  FIG. 3 . That is, a tube length of the deformable moving unit  40 H is stipulated by a fixed position of a fixing tool of  FIG. 3 . 
     Here, the deformable moving unit  40 H is briefly described. The ink supply tubes  40  displayed by a solid line in  FIG. 3  is one when the carriage  21  is positioned in a home position, and a curved portion  40 C of the ink supply tubes  40  when the carriage  21  is positioned at a reverse home position is displayed by double dashed line in the same figure. In an example of  FIG. 3 , a plurality of ink supply tubes  40  is disposed in a surface shape by being arranged substantially in a line in a radial direction so that the central line thereof may be substantially positioned on the same surface. Then, the plurality of ink supply tubes  40  is curbed in a cylindrical surface shape in the middle, and both side portions (tube surface) interposing the curved portion are disposed so as to face each other in a vertical direction and extend substantially in parallel. 
     When the carriage  21  is moved, the curved portion  40 C of the ink supply tubes  40  moves at a movement distance (in order words, movement speed) of about half of the movement distance (that is, movement speed) of the carriage  21  in a carriage movement direction. At this time, in a course where the carriage  21  moves from the home position to the reverse home position, the ink supply tubes  40  follow a movement of the carriage  21  while moving the curved portion  40 C to the left in  FIG. 3 . The ink supply tubes  40  deform the curved portion  40 C while changing a position of the curved portion  40 C in the main scanning direction X during a movement course of the carriage  21 . Therefore, the ink supply tubes  40  in a movement course of the carriage  21  is neither bent nor broken. Accordingly, even during the movement of the carriage  21 , it is possible to smoothly supply an ink to the adapter AD on the carriage  21  through the ink supply tubes  40 . In addition, the ink supply tubes  40  are broken and in contact with the sheet P or a roller  24  of a transport system, a timing belt  27  or the like, thereby it is easy to avoid a situation where a defective printing is incurred. 
     As illustrated in  FIG. 3 , the carriage  21  moves from a position where the curved portion  40 C is closest to the carriage  21  (home position in  FIG. 3 ) to a position where the curved portion  40 C is most apart from the carriage (reverse home position). In a course where the carriage  21  entirely moves a movement region, a portion contributing to the formation of the curved portion  40 C in the ink supply tubes  40  is a deformable moving unit  40 H. Then, in a position of the curved portion  40 C (a position of the curved portion  40 C illustrated by double dashed line in  FIG. 3 ), a portion on further upstream side in an ink supply direction than the curved portion  40 C is non-moving portion which does not contribute to the formation of the curved portion. Here, the boundary portion between the deformable moving unit  40 H and the non-moving portion may be fixed by the fixing portion. However, in the embodiment, in order to have some room, a portion of the ink supply tubes  40  is fixed to a position on further upstream side than the boundary portion by a predetermined distance. For example, it is preferable that the predetermined distance be set to a value which is equal to or lower than a distance of a longer one of a distance corresponding to 30% of the tube length of the deformable moving unit  40 H and 5 cm. When fixing the ink supply tubes  40  at a position far exceeding a predetermined distance from the boundary portion to the upstream side, this is to avoid as much as possible a situation where a portion which does not contribute to formation of curved portion becomes long and the shape maintenance of the deformable moving unit  40 H is unstable and a tube portion forming the deformable moving unit  40 H is broken. Of course, a portion fixing the ink supply tubes  40  using the third fixing tool  63  (for example, adhesive tape) may be a boundary portion or a portion exceeding a predetermined distance from the boundary portion to an upstream side. 
     Then, in the embodiment, the third fixing tool  63  fixes a portion on the upstream side of the ink supply tubes  40  instead of a substantially central portion in the movement region of the carriage  21 . Therefore, the ink supply tubes  40  have the left side portion a little shorter than the right side portion in  FIG. 3 , and both sides of a movement range of the carriage  21  centered on the fixing portion have the substantially the same length. In the embodiment, a portion between the boundary portion of the ink supply tubes  40  and a non-moving portion and the holding member  44  is the deformable moving unit  40 H. 
     Incidentally, as shown in  FIG. 3 , in the embodiment, it is preferable that the ink supply tubes  40  be configured to have a plurality of tubes  40 A and  40 B connected through a joint  40 J in the longitudinal direction. The joint  40 J is provided in a plurality of locations according to the number of tubes connected between the ink tank  19 T and the carriage  21 , and enables an ink to flow between the connected tubes. In an example shown in  FIG. 3 , the joint  40 J connects two tubes  40 A and  40 B on a support plate  41  of the ink supply tubes  40 . Each tube  40 A and  40 B connected to the both sides of the joint  40 J is fixed using a second fixing tool  62  and a third fixing tool  63  (for example, adhesive tape), so that the tubes  40 A and  40 B are unlikely to deviate from the joint  40 J. 
     The joint  40 J used in the embodiment, as illustrated in  FIG. 4 , has a joint main body  45  in a cylindrical shape and a pair of tube portions  46  projecting from the both end surfaces of the joint main body  45  in an axis direction. The pair of tube portions  46  communicates with each other in the axis direction. In addition, the joint  40 J, as illustrated in  FIG. 5 , has a joint main body  45  in a rectangular plate shape and four pairs of tube portions  46  with every four tube portions projecting from the both end surfaces of the joint main body  45  in the axis direction. In the four pairs of tube portions  46 , two tube portions forming a pair communicate with each other in the axis direction. 
     A joint portion of the tubes  40 A and  40 B connected through the joint  40 J are positioned at portions in addition to the deformable moving unit  40 H of the ink supply tubes  40  as illustrated in  FIG. 3 . Therefore, a location connected using the joint  40 J of the ink supply tubes  40  is not a curved portion  40 C, so that the tube is unlikely to deviate from the joint  40 J. 
     Next, as illustrated in  FIG. 6 , in the embodiment, the ink supply tubes  40  may be pulled around so that a portion where the curved portion  40 C of the deformable moving unit  40 H is formed may be opposite to  FIG. 3  with respect to the carriage  21 . In  FIG. 6 , some configuration members such as transportation mechanism of sheet P seen from the opening portion  12 K and a moving mechanism of the carriage  21  are omitted. 
     In an example of  FIG. 6 , the tank unit  19  is disposed on the outside of the movement region of the carriage  21 , in particular, on the outside of a home position side of the housing  12 H. The ink supply tubes  40  first extend from the tank unit  19 , and extend from the right side surface of the apparatus main body  12  in  FIG. 6  and slightly back side in the main scanning direction X to be fixed to a portion disposed on the upper surface portion  12 U by the first fixing tool  61  (for example, adhesive tape). Then, the middle portion of the downstream side which is a connection side with the adapter AD in the ink supply tubes  40  is sequentially fixed to the upper surface of the support plate  41  by the second fixing tool  62  and the third fixing tool  63  (respectively, for example, adhesive tape). The ink supply tubes  40  have a portion fixed to a further upstream side by a predetermined distance than the curved portion  40 C by the third fixing tool  63 , and the third fixing tool  63  functions as an example of the fixing portion. 
     A close portion to the adapter AD in the ink supply tubes  40  is bundled by a holding member  44  fixed to the left side surface of the carriage in  FIG. 6 , and an end portion further downstream side than a position bundled by the holding member  44  is connected to a supply tube (not illustrated) on the upper surface of the adapter AD, respectively. In the embodiment, in the ink supply tubes  40 , a portion between a boundary portion with the non-moving portion and the holding member  44  is the deformable moving unit  40 H. In addition, in  FIG. 6 , the joint  40 J of the ink supply tubes  40  is provided when needed. In an example of  FIG. 6 , as illustrated in  FIG. 3 , both side portions interposing the joint  40 J connecting the tubes  40 A and  40 B are fixed to the upper surface of the support plate  41  using the second fixing tool  62  and the third fixing tool  63 . As illustrated in  FIG. 6 , the support plate  41  is adjusted to an angle rotated slightly in a clockwise direction with respect to the angle of the support plate  41  in  FIG. 3 . 
     Next, an operation of the printer  11  of the first embodiment will be described. 
     In the printer  11 , by fixing the ink supply tubes  40  so as not to relatively move with respect to the opening portion  12 K using the first to third fixing tools  61 ,  62 , and  63  (for example, adhesive tape), it is possible to easily form the fixing portion. In addition, by adjusting the angle of the support plate  41  and adjusting a fixed position of the third fixing tool  63 , it is possible to fix a portion of the upstream side with a predetermined distance from the deformable moving unit  40 H performing a follow-up deformation along the movement of the carriage  21 . 
     Furthermore, in a case where the ink supply tubes  40  are removed from the apparatus main body  12  so as to perform maintenance of the ink supply tubes  40 , it is possible to easily remove the ink supply tubes  40  from the apparatus main body  12  by peeling off the first to the third fixing tools  61 ,  62 , and  63  (for example, adhesive tape). 
     According to the first embodiment, it is possible to obtain the effects illustrated below. 
     (1) Since a portion of the ink supply tubes  40  (the middle portion) may be fixed so as not to relatively move with respect to the opening portion  12 K of the apparatus main body  12  (printing function unit  12 A), it is possible to stably form the deformable moving unit  40 H performing a follow-up deformation along the movement of the carriage  21  between the opening portion  12 K and the liquid ejecting head  22 . As a result, the ink supply tubes  40  can be inhibited from disturbing the movement of the carriage  21 . 
     (2) The deformable moving unit  40 H of the ink supply tubes  40  has substantially the same tube length at both sides in a movement range of the carriage  21 , so that it is possible to suppress the length of the ink supply tubes  40  present on the liquid ejecting head  22  side from the fixing portion to be relatively short. 
     (3) The third fixing tool  63  which is an example of the fixing portion is provided on a side rotatably supporting the image reading unit  13  with respect to the opening portion  12 K, so that when the image reading unit  13  opens the opening portion  12 K of the housing  12 H, a view in the opening portion  12 K is unlikely to be disturbed by the liquid supply tube. Therefore, it is relatively easy to check a shape in the apparatus main body  12  through the opening portion  12 K. For example, the shape of jam of the sheet P during a jam error of the sheet is easily checked and the processing of resolving the sheet jam may be performed in a relatively smooth way. 
     (4) By displacing the support plate  41  in a direction far away from a substantially central position in the main scanning direction X of the opening portion  12 K of the apparatus main body  12 , a user can easily insert the finger to the movement region of the carriage  21  through the opening portion  12 K of the apparatus main body  12  (printing function unit  12 A). Therefore, even if the carriage  21  is in the middle position of the movement region, it is possible to easily perform, for example, maintenance of the carriage  21  or the processing of the sheet jam. 
     (5) Since the support plate  41  is provided to be rotatable with respect to the upper surface portion  12 U of the apparatus main body  12 , it is possible to relatively easily realize a configuration where the support plate  41  may be displaced in a direction far from the substantially central position in the main scanning direction X of the opening portion  12 K of the apparatus main body  12 . 
     (6) By using screw holes formed for a screw fixing the locking member in the locking concave portion  12   d  provided on the upper surface portion  12 U in order to lock the image reading unit  13  in a close state with respect to the apparatus main body  12 , the screw  43  screwed into the screw hole is set to a rotation axis of the support plate  41 . Therefore, the support plate  41  can be rotatably supported at a substantially central position in the main scanning direction X of the opening portion  12 K, and even if a longitudinal direction of the support plate  41  is not largely inclined to the sub-scanning direction Y, it is possible to support an appropriate fixed location of the ink supply tubes  40 . Thus, it is possible to finish the support plate  41  in a relatively short length, for example, during maintenance or sheet jam processing, the support plate  41  avoided by rotation is not a significant obstacle. In addition, since existing screw holes are used, it is not necessary to perform an extra processing such as a screw hole processing in the housing  12 H. 
     (7) By connecting a plurality of tubes through the joint  40 J, it is possible to adjust the ink supply tubes  40  to be an appropriate length to pull around. In addition, since a plurality of tubes with a length relatively easy to handle needs to be pulled around, an operation of pulling around the ink supply tubes  40  is relatively simple. 
     (8) The joint portion of the tubes  40 A and  40 B connected through the joint  40 J are positioned at a portion in addition to the deformable moving unit  40 H of the ink supply tubes  40 . Therefore, a location connected using the joint  40 J of the ink supply tubes  40  is not the curved portion  40 C, so that a tube is unlikely to deviate from the joint  40 J. 
     (9) Since a plurality of ink tanks  19 T are provided, and a plurality of ink supply tubes  40  are pulled around according to the number of the ink tanks  19 T, it is possible to supply a plurality of colors of ink through the plurality of ink supply tubes  40  to the liquid ejecting head  22  through each adapter AD to correspond to a color printing. 
     (10) The ink tank  19 T is positioned at the outside of the apparatus main body  12  (printing function unit  12 A), a restriction on an ink containing amount is eased. Therefore, it is possible to include the ink tank  19 T which can contain a large amount of ink. 
     (11) In the containing unit  12 S formed by the housing portion formed to project to the front surface portion of the housing  12 H, the sheet feeding cassette  15  is contained so as to align the front surface with the containing unit  12 S, at a ratio of configuration of enabling the sheet to be supplied from the front surface side of the apparatus main body  12 , it is possible to relatively inhibit the printer  11  from being larger (in particular, increase in a printer low surface area). In addition, a base portion  12 B of the operation panel unit  18  is configured by the housing portion indicating an inclined surface whose lower side further projects to a discharge direction (that is, the sub-scanning direction Y) side of the sheet P than the upper side. Then, on the inclined surface of the base portion  12 B, a display unit  18   a  (for example, liquid crystal display) and an operation button  18   b  are attached. Therefore, visibility of the display unit  18   a  is improved, and operability of the operation button  18   b  is also well ensured. 
     Second Embodiment 
     Next, a configuration of a second embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIGS. 7 and 8 . In description of  FIGS. 7 and 8 , the same reference numbers are given to configuration members the same as in  FIGS. 1 to 3 , and the description thereof will be omitted. In addition, the joint  40 J of the ink supply tubes  40  will not be illustrated in  FIGS. 7 and 8 . 
     An example of the fixing portion of a second embodiment, as illustrated in  FIG. 7 , is an inclined block  65  fixed to a portion of the peripheral portion of the opening portion  12 K in the upper surface portion  12 U of the housing  12 H. The inclined block  65  holds a surface (tube surface) through each central axis of each of a plurality of ink supply tubes  40  in a state of being inclined at a predetermined angle with respect to the opening surface of the opening portion  12 K. The holding member  66  where a portion of the adapter AD side of the ink supply tubes  40  is fixed to a side surface of the carriage  21  in a state where a portion of the adapter AD side of the ink supply tubes  40  is bundled holds a portion extending along the main scanning direction X from the holding member  66  to the upstream side to be inclined in the same direction as inclined by the inclined block  65 . 
     A detailed configuration will be described using  FIG. 8 .  FIG. 8  illustrates a schematic cross-section cut at the location of the holding member  66  fixed to the side surface of the carriage  21  in the main scanning direction X in  FIG. 7  and viewing the curved portion  40 C side. As illustrated in  FIG. 8 , the inclined block  65  has a triangular shape, and is fixed to the upper surface portion  12 U in a direction where the inclined surface  65   a  thereof extends in the main scanning direction X. In the inclined surface  65   a , a plurality of ink supply tubes  40  (four in the example) are fixed by the third fixing tool  63  (for example, adhesive tape) in a state of being arranged in a row. 
     On the other hand, as illustrated in  FIG. 8 , a holding member  66  fixed to the side surface of the carriage  21  is formed on the inclined surface  66   a  which is a surface of a side opposite to the inclined block  65  and in parallel with the inclined surface  65   a . Therefore, a plurality of tubes extending from the adapter AD and bundled using the holding member  66  are held in a state of being arranged in a row so as to form a tube surface substantially in parallel with the tube surface of the inclined block  65  side along the inclined surface  66   a . Then, the deformable moving unit  40 H is formed in a state where both sides of the tube surfaces are obliquely inclined across the curved portion  40 C. 
     Therefore, even in a configuration in which a space for pulling around the ink supply tubes  40  in the opening portion  12 K of the housing  12 H, it is possible to form the deformable moving unit  40 H so as to form the tube surface which is obliquely opposite to the opening surface of the opening portion  12 K in a substantially parallel way. 
     According to the above-mentioned second embodiment, it is possible to obtain the following effects in addition to effects (1) to (11) in the above-mentioned first embodiment. 
     (12) Even in a configuration where a space for pulling around the ink supply tubes  40  can not be ensured in the opening portion  12 K of the housing  12 H, it is possible to form the deformable moving unit  40 H so as to form a tube surface which is obliquely opposite to the opening surface of the opening portion  12 K in a substantially parallel way. 
     Third Embodiment 
     Next, a configuration of a third embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIGS. 9 and 10 . In description of  FIGS. 9 and 10 , the same reference numerals are given to the configuration members the same as in FIGS.  1  to  3 , the description for these is omitted. In addition, the joint  40 J of the ink supply tubes  40  will not be illustrated in  FIGS. 9 and 10 . 
     An example of the fixing portion in the third embodiment, as illustrated in  FIG. 7 , is the third fixing tool  63  (for example, adhesive tape) fixing a portion of the ink supply tubes  40  to the peripheral portion of the opening portion  12 K in the upper surface portion  12 U of the housing  12 H. 
     More specifically, the ink supply tubes  40  first extend from the tank unit  19 , and extend from the right side surface and slightly back side in  FIG. 10  of the apparatus main body  12  in the main scanning direction X to be fixed to a portion disposed on the upper surface portion  12 U by the first fixing tool  61 . Then, the middle portion of the downstream side which is a connection side to the adapter AD in the ink supply tubes  40  is sequentially fixed to a portion disposed on the upper surface portion  12 U by the second fixing tool  62  and the third fixing tool  63 . 
     In addition, as illustrated in  FIG. 10 , the close portion to the adapter AD in the ink supply tubes  40  is fixed to the upper surface of the front end portion of the support member  68  obliquely extending from the back surface portion of the carriage  21  to the rearward upside (backward upside) in a state of being bundled by the adhesive tape  69 . Then, each end portion of the downstream side is connected to the supply tube (not illustrated) on the upper surface of the adapter AD rather than a location fixed by the adhesive tape  69  to the support member  68  in the ink supply tubes  40 . 
     A portion of the ink supply tubes  40  is fixed further to a position on the upstream side than the boundary portion with a non-moving portion by a predetermined distance by the third fixing tool  63 , and accordingly the deformable moving unit  40 H is formed further downstream side than the fixed position thereof. 
     A detailed structure will be described using  FIG. 9 .  FIG. 9  illustrates a schematic cross-section cut at the location of the support member  68  fixed to the back surface portion of the carriage  21  in the main scanning direction X in  FIG. 10  and viewing the curved portion  40 C side. More specifically, as illustrated in  FIG. 9 , the support member  68  where a base portion is fixed to a back surface portion of the carriage  21  has the support portion  68   a  which obliquely extends to upward rear side and then extends to rearward in a substantially parallel way. The support portion  68   a  is positioned at a height spaced away from the upper surface of the peripheral portion of the opening portion  12 K by a predetermined space distance. On the upper surface of the support portion  68   a , a portion of the plurality of ink supply tubes  40  is fixed using the adhesive tape  69 . 
     Therefore, a plurality of tube portions (tube surfaces) disposed on the upper surface of the rear side peripheral portion along the opening portion  12 K in the upper surface portion  12 U of the housing  12 H, and a plurality of tube portions (tube surface) supported on the upper surface of the support portion  68   a  which is the front end portion of the support member  68  are positioned to be opposite to each other in a vertical direction. Therefore, in a course of moving a space between a position (a home position in the example) of the carriage  21  illustrated by a solid line in  FIG. 10  and a position (an end position of reverse home position side in the example) of the carriage  21  illustrated by a double dashed line in the same figure, the deformable moving unit  40 H deforms the curved portion  40 C to be displaced in the main scanning direction X. 
     According to the structure, even in a configuration in which a space for pulling around the ink supply tubes  40  is hardly ensured in the opening portion  12 K of the housing  12 H, the ink supply tubes  40  may be disposed on the upper side of the housing  12 H, so that it is possible to supply an ink to each adapter AD on the carriage  21  from an external tank unit  19  while inhibiting the ink supply tubes  40  from being broken. 
     Fourth Embodiment 
     Next, a configuration of fourth embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIG. 11 . In description of  FIG. 11 , the same reference numerals are given to the configuration members the same as in  FIGS. 1 to 3 , the description for these is omitted. In addition, the joint  40 J of the ink supply tubes  40  will not be illustrated in  FIG. 11 . 
     An example of the fixing portion in the fourth embodiment is basically the same as in  FIG. 3 . In the embodiment, as illustrated in  FIG. 11 , a plurality ((N+M), for example, four) of ink supply tubes  40  extending from each of a plurality of adapters AD is divided into N (for example, two) and the remaining M (for example, two) (here, N and M are natural numbers). Then, one end portion of N ink supply tubes  40  is connected to each ink tank  19 T in the tank unit  19 A disposed outside of the left side (reverse home position side) of the housing  12 H, thereby connecting an end portion of the M ink supply tubes  40  to each ink tank  19 T in a tank unit  19 B disposed outside of the right side (home position side) of the housing  12 H. 
     N ink supply tubes among the plurality of ink supply tubes  40  are fixed using the first fixing tool  61  (for example, adhesive tape) to the left end portion of the upper surface portion  12 U of the housing  12 H, and furthermore a portion of the downstream side is fixed to the upper surface of the support plate  41  using the second fixing tool  62  and the third fixing tool  63 . On the other hand, the remaining M ink supply tubes  40  are fixed using the fixing tools  71  and  72  (for example, adhesive tape) to the peripheral portion of the rear side along the opening portion  12 K in the upper surface portion  12 U of the housing  12 H, a direction of pulling around the tube is inverted at a portion of the downstream side, and the inverted rear portion is fixed to the upper surface of the support plate  41  by the third fixing tool  63 . Then, after four ink supply tubes  40  fixed to the upper surface of the support plate  41  by the third fixing tool  63  are bundled by the holding member  44  where a portion on the downstream side extends in the same direction (rightward in  FIG. 11 ) and is fixed to the right side surface of the carriage  21 , each of the other end portions is connected to the supply tube (not illustrated) projecting from the upper surface of each adapter AD. In the embodiment, the both end portions of the support plate  41  in the longitudinal direction are fixed using an adhesive tape which is not illustrated, and a fixing method of using either adhesive or a screw. Of course, in a similar way as in the first embodiment, by rotatably supporting one end portion of the support plate  41  centered on a screw  43 , a configuration of fixing the other end portion using a known fixing tool such as adhesive tape and the like may be provided. Even if the plurality of ink supply tubes  40  are divided and pulled around in a horizontal direction, it is possible to obtain substantially the same effects as in the first embodiment. 
     Fifth Embodiment 
     Next, a configuration of the printer  11 A as a liquid ejecting apparatus which does not have an image reading function will be described referring to  FIGS. 12 to 14 . The printer  11  in the first to the fourth embodiments used to be a so-called multifunction unit, but the printer  11 A in the following embodiments includes a printing function unit (printer unit), but does not have an image reading unit (scanner unit). In description of  FIGS. 12 to 14 , the same reference numerals are given to the configuration members the same as in  FIGS. 1 to 3 , the description for these is omitted. A configuration of the fixing portion fixing the ink supply tubes  40  corresponds to the first embodiment applied to the printer  11 A of a single function only having a printing function. 
     As illustrated in  FIG. 12 , the printer  11 A of the embodiment includes a printing function unit  12 A formed of an apparatus main body  12  having a printing function. The printer  11 A receives a supply of an ink from the ink tank  19 T (refer to  FIG. 14 ) as an example of a liquid containing unit having a substantially rectangular shape as a separate body from the apparatus main body  12  thereof. Then, in the printer  11 A, an ink contained in the ink tank  19 T is supplied from the ink tank  19 T side positioned at the outside of the apparatus main body  12  to the apparatus main body  12  side through the ink supply tubes  40  (see  FIG. 14 ). 
     The apparatus main body  12  of the printer  11 A has the housing  12 H embedded with the printing unit  20 . A lid portion  75  as an example of a cover member rotates (displace) about a hinge  75   a  provided on one side end (rearward side) of the apparatus main body  12 , and the hinge  75   a  has a configuration in which the front end portion side (front end side in  FIG. 14 ) of the opposite side is lifted. For example, it is possible for a user of the printer  11 A to lift the lid portion  75  during maintenance. By the lifting, an opening portion  12 K (refer to  FIG. 14 ) exposing at least a portion of the movement region of the carriage  21  provided upward of the printing unit  20  and disposed to reciprocate in the printing function unit  12 A is exposed. 
     Furthermore, in the rear side of the lid portion  75  in the apparatus main body  12 , a manual sheet feeding mechanism  35  is provided. The manual sheet feeding mechanism  35  is an on-off type in which a cover  35   e  including the sheet feeding tray  35   a  (refer to  FIG. 13 ) may rotate around the rear end portion, and the cover  35   e  is held in a close state as illustrated in  FIG. 12  when not used. In the front end portion of the cover  35   e  in a close state, a grip portion  35   f  in a concave shape is formed, and a user grasps the grip portion  35   f  to rotate the cover  35   e  rearward, and accordingly the sheet feeding tray  35   a  is in an open state in use where the sheet feeding tray  35   a  obliquely rises (refer to  FIG. 13 ). A configuration of the manual sheet feeding mechanism  35  in an open state will be described below. 
     In addition, at the lower portion of the apparatus main body  12 , the sheet feeding cassette  15  which may overlap and contain a plurality of sheets P is detachably provided. The sheet P contained in the sheet feeding cassette  15  is fed from the rear to the front to the printing unit  20  provided in the printing function unit  12 A one by one, and a printing is performed by the printing unit  20  with respect to the fed sheet P. A configuration of the printing unit  20  is basically the same as one of the printer  11  in the first embodiment. Then, the printed sheet P where a printing is finished by the printing unit  20  is discharged from the sheet discharge port  16  provided at the front surface of the apparatus main body  12  (printing function unit  12 A). 
     In the apparatus main body  12  (printing function unit  12 A), the upstream of the sheet feeding cassette  15  or the downstream of the sheet discharge port  16 , the stacker  17  as an example of a discharge tray is accommodated. The stacker  17  is used by pulling a length corresponding to the size of the sheet P from the apparatus main body  12  in a discharge direction (transportation direction) of the sheet P. 
     The containing unit  12 S having a containing concave unit containing the sheet feeding cassette  15  and the stacker  17  at a central portion in the width direction is configured using a housing portion formed to project to the discharge direction (here, a sub-scanning direction Y) of the sheet P. Allowing the containing unit  12 S to project is because a required length of the sheet feeding cassette  15  in the sub-scanning direction Y is longer than the required length of the housing  12 H in the sub-scanning direction in the printing unit  20 . Therefore, the sheet feeding cassette  15  and the stacker  17  is contained so as to align the front end surface with the containing unit  12 S in a state of projecting from the apparatus main body  12  to the sub-scanning direction Y (frontward). Specifically, When determining the length of the apparatus main body  12  in the sub-scanning direction Y according to the length of the sheet feeding cassette  15  in the sub-scanning direction Y which is needed to contain the sheet P of a predetermined size (as an example, A4), the apparatus main body  12  gets larger (an increase in the lower area). In order to avoid this even a little, the containing unit part of the sheet feeding cassette  15  only is allowed to project. In other words, by making a shape of gouging out the outside of the containing unit  12 S in the width direction, it is possible to inhibit the lower surface area of the printer  11 A from increasing. In addition, the front surface position when accommodating the stacker  17  is determined according to the projected front surface position of the sheet feeding cassette  15 , so that a projecting length of the stacker  17  when pulled out is ensured to be relatively long. Further, by the projection, the stacker  17  may easily be pulled out from the apparatus main body  12  by a grip portion  17   a . The sheet feeding cassette  15  is detachably provided at the front surface of the apparatus main body  12 , and relatively inhibiting the printer  11 A (in particular, increase in the printer lower surface area) from being larger by the configuration in which the feeding from the front surface side of the apparatus main body  12  is possible. 
     On the other hand, as illustrated in  FIG. 12 , on the upper portion of the apparatus main body  12  (printing function unit  12 A), an operation panel unit  18  for performing various types of operation such as performing a printing operation using the printing unit  20  and the like is disposed. The operation panel unit  18  is configured by a housing portion having an inclined surface whose lower side further projects to the discharge direction (that is, the sub-scanning direction Y) of the sheet P than the upper side. Then, an operation button  18   b  is provided on the inclined surface of the operation panel unit  18 . In the operation button  18   b , there are, for example, a power button and a printing start button and the like. The operation surface of the operation panel unit  18  is an inclined surface with the front falling, thereby satisfactorily securing the operability of the operation button  18   b  for the user. 
     In addition, as illustrated in  FIG. 13 , on the back surface side of the apparatus main body  12  (printing function unit  12 A), the manual sheet feeding mechanism  35  is mounted. The manual sheet feeding mechanism  35  is a mechanism for a user&#39;s manual setting and feeding one sheet P. The manual sheet feeding mechanism  35  includes the sheet feeding tray  35   a  in a substantially rectangular plate shape, a pair of sheet guide  35   b  for an operation of determining a position in the width direction on the sheet feeding tray  35   a , and a protective plate  35   c  provided for a purpose of preventing debris and the like from falling to the feeding port (not illustrated) in an open state of the manual sheet feeding mechanism  35 . The sheet feeding tray  35   a  is provided to be rotatably operated in a predetermined angle range around the base end portion (a lower end portion in  FIG. 13 ), and disposed in an open state illustrated in  FIG. 13  in which the sheet P is inclined to be set, or in a close state where the sheet is rotated from the open state to the front side of  FIG. 13  to be accommodated in the apparatus main body  12 . The protective plate  35   c  is biased in a direction approaching the sheet feeding tray  35   a  side by elasticity of the torsion coil spring  35   g , and when opening the sheet feeding tray  35   a , is disposed at a protective position illustrated in  FIG. 13  which prevent the debris fallen to the opened location from entering the feeding port. 
     In addition, as illustrated in  FIG. 13 , the stacker  17  is three-stage way as an example, and includes a first tray  17   b , a second tray  17   c  and a third tray  17   d . The first tray  17   b  is slidably connected to the apparatus main body  12 , and the second tray  17   c  is slidably connected to the first tray  17   b . Then, the third tray  17   d  is rotatably connected to the front end portion of the second tray  17   c , and is disposed in a close position of being accommodated in a state overlapping with respect to the second tray  17   c , and an open position functioning as a stopper of the sheet lifted in a rising pose at a predetermined angle as illustrated in  FIG. 2 . 
     As illustrated in  FIG. 14 , on the back surface of the lid portion  75 , at a close position of the rotation front end side in the width direction, a projection  37  for object detection is formed to project. The projection  37 , when closing the lid portion  75 , is inserted into the detected concave portion  38  provided to be concaved on the upper surface of the apparatus main body  12 . In the apparatus main body  12 , at a position corresponding to the detected concave portion  38 , a sensor (not illustrated) detecting the projection  37  inserted to the detected concave portion  38  is provided. A controller in the printer  11 A, when detecting a close state of the lid portion  75 , performs an instructed printing. However, when the sensor does not detect the close state of the lid portion  75 , the controller is not allowed to start the printing even though there is an instructed printing. 
     Next, a configuration of a fifth embodiment regarding a fixing portion that fixes the ink supply tube  40  will be described with reference to  FIG. 14 . The fixing portion of the fifth embodiment has a configuration in which the ink supply tube  40  is fixed to the housing  12 H that forms the opening portion  12 K using the fixing tool. Meanwhile, it is possible to use a variety of members such as a cord, a rubber band, a clip, an adhesive tape and an adhesive as the fixing tool. That is, in the present embodiment, an example in which an adhesive tape is used as the fixing tool will be described. In addition, in descriptions of  FIGS. 12 to 14 , the same components as in  FIG. 1  will be given the same reference numerals, and will not be appropriately described. 
     In the embodiment, first, a configuration of a printing unit  20  will be simply described using  FIG. 14 . 
     As illustrated in  FIG. 14 , the carriage  21 , the liquid ejecting head  22 , a support table  23 , the transportation roller  24 , the sheet discharge roller  25 , the guide frame  30 , the timing belt  27 , the linear encoder  28  and the like are provided in the housing  12 H. 
     Inks used in the liquid ejecting head  22  for the printing are supplied to the liquid ejecting head  22  from the respective ink tanks  19 T in the external tank unit  19  through the respective ink supply tubes  40  and the respective adapters AD. In the tank unit  19  of the present example, four ink tanks  19 T that respectively house four inks having different ink colors are housed as an example. The four ink colors are, for example, black (K), cyan (C), magenta (M) and yellow (Y). 
     As illustrated in  FIG. 14 , the ink tanks  19 T are disposed on an outside of a movement region of the carriage  21 , and, particularly, in the example, disposed on an outside of the housing  12 H. The ink tanks  19 T are provided on a left outside of the housing  12 H, that is, at a location on an opposite side of a home position in the main scanning direction X when seen from a front side (a front side of the sub-scanning direction Y) of the printer  11 A. In addition, one end portion of the ink supply tube  40  is connected to the ink tanks  19 T, and a portion of the ink supply tube  40  on an opposite side is inserted into the movement region of the carriage  21  exposed from a location closer to the home position in the main scanning direction X of the carriage  21  through the opening portion  12 K provided in the housing  12 H. The other inserted end portion is connected to the adapter AD mounted on the carriage  21 . The respective ink supply tubes  40  connected between the tank unit  19  and the adapter AD on the carriage  21  are installed in a state of extending almost straight along the main scanning direction X over an inside portion of the opening portion  12 K when a side to which the lid portion  75  is rotatably fixed is considered as the inside. 
     As illustrated in  FIG. 14 , the long and thin plate-like support plate  41  is provided on a top surface of the housing  12 H in a state of being bridged laterally so as to traverse the opening portion  12 K in the sub-scanning direction Y. A length of the support plate  41  in a longitudinal direction is slightly longer than a width of the opening portion  12 K in the sub-scanning direction Y. The support plate  41  is rotatably provided at an end portion using the axis portion  41   a . Therefore, an angle formed by the longitudinal direction of the support plate  41  with the main scanning direction X becomes changeable by rotating the support plate  41  around the axis portion  41   a  in a plane in parallel with an opening surface of the opening portion  12 K. 
     In addition, an end portion (free end) of a side opposite to the rotating center of the support plate  41  having an adjusted angle on a position fixed to a portion of the ink supply tube  40  is fixed to a upper surface portion  12 U of the housing  12 H using a fixing tool (for example, an adhesive tape), not shown, at a location to which a part of the ink supply tube  40  is fixed. Naturally, the free end portion of the support plate  41  having an adjusted angle may be fixed using a screw or an adhesive. Meanwhile, on the upper surface portion  12 U of the apparatus main body  12 , the detected concave portion  38  into which the projection  37  provided on a rear surface of the lid portion  75  is inserted when the lid portion  75  is opened is formed on a left side of the operation panel unit  18  in  FIG. 14 . In addition, on the upper surface portion  12 U of the housing  12 H, the ventilating port  47  is formed around the opening portion  12 K. 
     In addition, on the upper surface of the housing  12 H, bosses  29  having a substantially columnar shape are fixed in a state of projecting upward in a predetermined length. That is, the bosses  29  are provided in order to ensure a gap through which the ink supply tube  40  is inserted between the lid portion  75  and the printing function unit  12 A by being sandwiched between the printing function unit  12 A and the image reading unit  13  in a case in which the lid portion  75  is rotated in a closing direction in which the opening portion  12 K is opened and closed. Meanwhile, in  FIG. 14 , in order to stably form the gap, two bosses  29  are provided, but one boss  29  may be provided. 
     Meanwhile, a middle portion of the ink supply tube  40  inserted into the gap formed using the bosses  29  as described above in the longitudinal direction is fixed to the upper surface of the housing  12 H using a fixing tool. In the embodiment, an example in which the bosses are fixed using three adhesive tapes will be described. Originally, a number of adhesive tapes necessary to fix the ink supply tube  40  are used. 
     More specifically, the ink supply tubes  40  first extend from the tank unit  19  and is fixed by the first fixing tool  61  (for example, adhesive tape) attached at a portion disposed on the upper surface portion extending from the left side surface and the slightly back side of the apparatus main body  12  in  FIG. 14 . Next, the middle portion on the downstream side which is a connection side to the adapter AD rather than the ink supply tubes  40  is sequentially fixed using the second fixing tool  62  (for example, adhesive tape) and the third fixing tool  63  (for example, adhesive tape) attached to the upper surface of the support plate  41 . 
     In addition, as illustrated in  FIG. 14 , a close portion to the adapter AD in the ink supply tubes  40  is bundled and held by the holding member  44  fixed to the right side surface of the carriage  21  in  FIG. 14 , an end portion of the downstream side rather than a position bundled by the holding member  44  is respectively connected to the supply tube (not illustrated) on the upper surface of the adapter AD. 
     The middle portion fixed using the first to the third fixing tools  61 ,  62 , and  63  in the ink supply tubes  40  is restricted to move in the length direction of the ink supply tubes  40  and a direction intersecting with the length direction. 
     Therefore, the first to the third fixing tools  61 ,  62 , and  63  fixing the middle portion of the ink supply tubes  40  function as an example of the fixing portion. 
     Then, in the embodiment, among the first to the third fixing tools  61 ,  62 , and  63 , the third fixing tool  63  fixing the middle portion of the most downstream side of the ink supply tubes  40  to the housing  12 H is a fixing portion fixing a portion of the ink supply tubes  40  in the length direction to be relatively immovable with respect to the opening portion  12 K. As the result, a portion between the third fixing tool  63  and the adapter AD in the length direction of the ink supply tubes  40 , more accurately a portion between the third fixing tool  63  and the holding member  44  is a deformable moving unit  40 H performing a follow-up deformation along the movement of the carriage  21  as illustrated in  FIG. 14 . In other words, the tube length of the deformable moving unit  40 H is restricted by a fixed position of the third fixing tool  63 . 
     In the example of  FIG. 14 , a plurality of ink supply tubes  40  are disposed in a surface shape by being substantially arranged in a row in the radial direction so that each central line is substantially positioned on the same surface. Then, the plurality of ink supply tubes  40  are curved in an arc surface shape in the middle, both side portions (tube surface) across the curved portion is disposed to extend opposite to a vertical direction in a substantially parallel way. 
     When the carriage  21  moves, the curved portion  40 C of the ink supply tubes  40  moves by a movement distance (in other words, movement speed) of approximately half of the movement distance (that is, movement speed) of the carriage  21  in the carriage movement direction. At this time, in a course where the carriage  21  moves from the home position to the reverse home position, the ink supply tubes  40  follow the movement of the carriage  21  while moving the curved portion  40 C leftward in  FIG. 14 . Therefore, in the course of movement of the carriage  21 , the ink supply tubes  40  may smoothly supply an ink to the adapter AD on the carriage  21  through the ink supply tubes  40  without being curved or broken. It is easy to avoid a situation incurring a print failure by a reason that the ink supply tubes  40  are broken to be in contact with, for example, the sheet P or the transportation roller  24 , the timing belt  27  and the like. 
     As illustrated in  FIG. 14 , in a course that the carriage  21  entirely moves the movement region, a portion contributing to formation of the curved portion  40 C in the ink supply tubes  40  is a deformable moving unit  40 H. Then, a portion on the upstream side of an ink supply direction rather than the curved portion  40 C is a non-moving portion which does not contribute to formation of the curved portion. Here, the boundary portion of the deformable moving unit  40 H and the non-deformable portion may be fixed using the fixing portion. However, in the embodiment, in order to have some room, a portion of the ink supply tubes  40  may be fixed to a position on an upstream side by a predetermined distance rather than the boundary portion. When the ink supply tubes  40  are fixed to a position greatly exceeding a predetermined distance from the boundary portion to the upstream side, a portion where a portion which does not contribute to formation of the curved portion is not fixed is long, thereby extremely avoiding a situation where the tube portion forming the deformable moving unit  40 H whose shape is unstably held is broken. Of course, a portion fixing the ink supply tube  40  by the third fixing tool  63  (fixing portion) may be a boundary portion or a portion exceeding a predetermined distance from the boundary portion to the upstream side. 
     Then, in the embodiment, the third fixing tool  63  fixes a portion on the upstream side of the ink supply tubes  40  rather than a substantially central portion in the movement region of the carriage  21  in the main scanning direction X. Therefore, the ink supply tubes  40  have the left side portion slightly shorter than the right side portion in  FIG. 14 , and both sides of the movement range of the carriage  21  centered on the fixing portion by the third fixing tool  63  have a substantially the same length. 
     Incidentally, as illustrated in  FIG. 14 , in the embodiment, it is preferable that the ink supply tubes  40  be configured to have a plurality of tubes  40 A and  40 B connected through the joint  40 J in the longitudinal direction. The joint  40 J, as illustrated in  FIG. 14 , two tubes  40 A and  40 B are connected on the support plate  41  of the ink supply tubes  40 . Each tube  40 A and  40 B connected to both sides of the joint  40 J is fixed by the second fixing tool  62  and the third fixing tool  63 , so that the tubes  40 A and  40 B are unlikely to deviate from the joint  40 J. 
     The joint  40 J used in the embodiment includes the joint  40 J illustrated in  FIG. 4  and the joint  40 J illustrated in  FIG. 5 . The joint portion of the tubes  40 A and  40 B connected through the joint  40 J is positioned at a portion in addition to the deformable moving unit  40 H of the ink supply tubes  40  as illustrated in  FIG. 14 . Therefore, a location connected using the joint  40 J of the ink supply tubes  40  is not the curved portion  40 C, so that the tube is unlikely to deviate from the joint  40 J. 
     According to a fifth embodiment described above, effects (1) to (11) in the first embodiment are obtained in the same manner. 
     Sixth Embodiment 
     Next, a configuration of a sixth embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIG. 15 . The sixth embodiment is an example applying a configuration pulling around the ink supply tubes  40  in the second embodiment to the printer  11 A. In description of  FIG. 15 , the same numbers are given to the same configuration members in  FIGS. 12 to 14 , and the description is omitted. In addition, the joint  40 J of the ink supply tubes  40  is not illustrated in  FIG. 15 . 
     An example of the fixing portion of the sixth embodiment, as illustrated in  FIG. 15 , is an inclined block  65  fixed to a portion of the peripheral portion of the opening portion  12 K on the upper surface portion of the housing  12 H. The inclined block  65  holds a plurality of ink supply tubes  40  inclined at a predetermined angle on a surface (tube surface) which is through each central line with respect to the opening surface of the opening portion  12 K. The holding member  66 , fixed to a side surface of the carriage  21  in a state where a portion of the adapter AD side of the ink supply tubes  40  is bundled, inclines and holds a portion extending along the main scanning direction X from the holding member  66  to the upstream side so as to be inclined in the same direction as inclined by the inclined block  65 . 
     In a detailed configuration, as illustrated in  FIG. 8 , the inclined block  65  has a triangular shape, and the inclined surface  65   a  is fixed to the upper surface portion  12 U in a direction extending in the main scanning direction X. A plurality (four in the example) of ink supply tubes  40  are fixed to the inclined surface  65   a  by the third fixing tool  63  (for example, adhesive tape) in a state of being arranged in a row. 
     On the other hand, as illustrated in  FIG. 8 , the holding member  66  fixed on the side surface of the carriage  21  is formed on the inclined surface  66   a  where a surface of a side opposite to the inclined block  65  is in parallel to the inclined surface  65   a . Therefore, a plurality of tubes bundled by the holding member  66  extending from the adapter AD are held in a state of being arranged in a row so as to form a tube surface in substantially parallel to a tube surface of the inclined block  65  side along the inclined surface  66   a . Then, the deformable moving unit  40 H is formed in a state where both sides of the tube surface are obliquely oppose each other across the curved portion  40 C in a substantially parallel way. 
     Therefore, even in a configuration where a space for pulling around the ink supply tubes  40  cannot be ensured in the opening portion  12 K of the housing  12 H, it is possible to form the deformable moving unit  40 H so as to form a tube surface obliquely opposite to the opening surface of the opening portion  12 K in a substantially parallel way. It is possible to obtain the same effects as (1) to (11) in the first embodiment. 
     Seventh Embodiment 
     Next, a configuration of a seventh embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIG. 16 . The seventh embodiment is an example which applies a structure of pulling around the ink supply tubes  40  in the third embodiment to the printer  11 A. In description of  FIG. 16 , the same numbers are given to the same configuration members in  FIGS. 12 to 14 , and the description is omitted. In addition, the joint  40 J of the ink supply tubes  40  is not illustrated in  FIG. 16 . 
     An example of the fixing portion in the seventh embodiment, as illustrated in  FIG. 16 , is the third fixing tool  63  (for example, adhesive tape) fixing a portion of the ink supply tubes  40  to the peripheral portion of the opening portion  12 K on the upper surface portion of the housing  12 H. Specifically, the ink supply tubes  40  first extends from the tank unit  19  and is fixed by the first fixing tool  61  to a portion extending from the right side surface and the slightly back side to the main scanning direction X in  FIG. 16  of the apparatus main body  12  and disposed on the upper surface portion. Next, the middle portion of the downstream side which is rather a connection side to the adapter AD in the ink supply tubes  40  is sequentially fixed by the second fixing tool  62  and the third fixing tool  63  to a portion disposed on the upper surface portion. 
     In addition, as illustrated in  FIG. 16 , a close portion to the adapter AD in the ink supply tubes  40  is fixed to the front end portion upper surface of the support member  68  obliquely extending from the back surface portion of the carriage  21  to rearward upside (backward upside) in a state of being bundled using the adhesive tape  69 . Then, the end portion of the downstream side rather than a location fixed by the adhesive tape  69  to the support member  68  in the ink supply tubes  40  is respectively connected to the supply tube (not illustrated) on the upper surface of the adapter AD. 
     A portion of the ink supply tubes  40  is fixed to a position of the further upstream side than the boundary portion of the non-moving portion as much as a predetermined distance by the third fixing tool  63 , and accordingly the deformable moving unit  40 H is formed at further downstream side than the fixed position thereof. 
     Specifically, as illustrated in  FIG. 9 , in the back surface portion of the carriage  21 , a support member  68  where the base end portion is fixed has the support portion  68   a  extending obliquely upward to the rear side and extending rearward in a substantially parallel way. The support portion  68   a  is positioned at a height spaced away as much as a predetermined space distance from the upper surface of the peripheral portion of the opening portion  12 K. On the upper surface of the support portion  68   a , a portion of the plurality of ink supply tubes  40  is fixed by the adhesive tape  69 . 
     Therefore, a plurality of tube portions (tube surface) disposed on the upper surface of the rear side peripheral portion along the opening portion  12 K in the upper surface portion  12 U of the housing  12 H, and a plurality of tube portions (tube surface) supported in the upper surface of the support portion  68   a  which is the front end portion of the support member  68  are positioned to be opposite to each other in a vertical direction. Therefore, in a course of moving a space between a position of the carriage  21  (home position in the example) illustrated using a solid line in  FIG. 16  and a position of the carriage  21  illustrated using the two-dot chain line in  FIG. 16  (end position on reverse home position side in the example), the deformable moving unit  40 H is deformed by displacing the curved portion  40 C in the main scanning direction X. 
     According to the configuration, even in a configuration in which a space for pulling around the ink supply tubes  40  in the opening portion  12 K of the housing  12 H, the ink supply tubes  40  may be disposed on the upper side of the housing  12 H, so that it is possible to supply an ink while inhibiting the ink supply tubes  40  from being broken from the external tank unit  19  to each adapter AD on the carriage  21 . It is possible to obtain the same effect as (1) to (11) in the first embodiment. 
     Eighth Embodiment 
     Next, a configuration of an eighth embodiment according to the fixing portion fixing the ink supply tubes  40  will be described referring to  FIG. 17 . The eighth embodiment is an example which applies a structure of pulling around the ink supply tubes  40  in the fourth embodiment to the printer  11 A. In description of  FIG. 17 , the same numbers are given to the same configuration members in  FIGS. 12 to 14 , and the description is omitted. In addition, the joint  40 J of the ink supply tubes  40  is not illustrated in  FIG. 17 . 
     An example of the fixing portion in the eighth embodiment is basically the same as in  FIG. 3 . In the embodiment, as illustrated in  FIG. 11 , a plurality ((N+M), for example four) of ink supply tubes  40  extending from each of a plurality of adapters AD are divided into N (for example, two) and the remaining M (for example, two) (Here, N and M are natural numbers). Then, by connecting an end portion of N ink supply tubes  40  to each ink tank  19 T in the tank unit  19 A disposed outside the left side (reverse home position side) of the housing  12 H, an end portion of M ink supply tubes  40  is connected to each ink tank  19 T in the tank unit  19 B disposed outside the right side (home position side) of the housing  12 H. 
     N among the plurality of ink supply tubes  40  are fixed by the first fixing tool  61  (for example, adhesive tape) to the left end portion of the upper surface portion  12 U of the housing  12 H, and furthermore a portion of the downstream side thereof is fixed to the upper surface of the support plate  41  by the second fixing tool  62  and the third fixing tool  63 . On the other hand, the remaining M ink supply tubes  40  are fixed by fixing tools  71  and  72  (for example, adhesive tape) to the peripheral portion of the rear side along the opening portion  12 K in the upper surface portion  12 U of the housing  12 H, a direction of pulling around a tube at a portion of the downstream side is inverted to an opposite direction, and a portion after being inverted is fixed to the upper surface of the support plate  41  by the third fixing tool  63 . Then, four ink supply tubes  40  fixed to the upper surface of the support plate  41  by the third fixing tool  63  has the downstream side portion that extends in the same direction (horizontal direction in  FIG. 17 ), and is bundled by the holding member  44  fixed to the right side surface of the carriage  21 , and then each of other end portions is connected to a supply tube (not illustrated) having each end portion projecting from the upper surface of the adapter AD. In the embodiment, both end portions of the support plate  41  in the longitudinal direction are fixed using a fixing method of any one of an adhesive and a screw. Of course, similar to the first embodiment, by supporting one end portion of the support plate  41  so as to rotate around the screw  43 , a configuration where the other end portion thereof is fixed using a known fixing tool such as adhesive tape and the like may be provided. Even if the plurality of ink supply tubes  40  are divided at the left and right and pulled around, it is possible to obtain substantially the same effects as in the fifth embodiment. 
     The above-mentioned embodiment may be changed to another embodiment as follows. 
     In the fifth to the eighth embodiments, the ink supply tubes  40  are described to be multiple. However, when one ink tank  19 T is included in the printer  11 A, a configuration supplying an ink to the liquid ejecting head  22  side from the ink tank  19 T side through one of the ink supply tubes  40  may be provided. As an example, in a configuration of pulling around the ink supply tubes  40  in the fifth embodiment, an example of one of the ink supply tubes  40  will be described using  FIG. 18 . As illustrated in  FIG. 18 , one of the ink supply tubes  40  extending from the ink tank  19 T is fixed by the second fixing tool  62  and the third fixing tool  63  at a portion supported by the support plate  41 . Then, the other end portion of the ink supply tubes  40  is connected to the adapter AD mounted on the carriage  21 . For example, if black ink is contained in the ink tank  19 T, a lot of black-and-white printings may be performed. Of course, in the sixth to the eighth embodiment, a configuration of pulling around one of the ink supply tubes  40  may be adapted. 
     In the above-mentioned first to the fourth embodiments, when the image reading unit  13  is rotated in a state in which the image reading unit  13  closes the opening portion  12 K of the printing function unit  12 A, in a case where a projection unit projecting to the printing function unit  12 A side in the swing direction of the image reading unit  13 , it is preferable that the ink supply tubes  40  be disposed at an avoidance position not crushed by the projection unit. 
     The support member does not need to have the length cross-cutting the opening portion  12 K, is shorter than the width in the sub-scanning direction Y of the opening portion  12 K, and may be used as a cantilever. In this case, a position attaching a cantilever type of support member to the upper surface portion  12 U may be at a position either the upstream side or the downstream side across the opening portion  12 K in the sub-scanning direction Y of the upper surface portion  12 U. 
     In each embodiment above-mentioned, a position of a fixing portion of the ink supply tubes  40  fixed by the third fixing tool  63  does not need to be a substantially central portion of the movement region of the carriage  21 . In short, it may be a position where the ink supply tubes  40  do not interfere with the movement of the carriage  21 . 
     It is sufficient that the support member may be provided so as to be displaced in a moving direction (main scanning direction X) of the carriage  21 . For example, the support member may be slidably provided in a moving direction. Furthermore, there may be no problem if the displacement direction may be in a vertical direction or in an oblique direction, not in a horizontal direction. 
     In each of the embodiments described above, the fixed position of the boss  29  may be another position. In addition, the shape of the boss  29  also is not limited to the cylindrical shape. It may have a polygonal shape. 
     In each of the embodiments described above, it may be configured that the adapter AD is not mounted on the carriage  21 . That is, it may have a configuration that the ink supplied from the ink tank  19 T provided on the outside of the printing function unit  12 A via the ink supply tubes  40  may be supplied to the liquid ejecting head  22  side without passing through the adapter AD. 
     In each of the embodiments described above, the ink tank  19 T may not be necessarily positioned on the outside of the apparatus main body  12  (printing function unit  12 A). For example, if it may be the outside of the movement region of the carriage  21 , there may be no problem if it is positioned inside the apparatus main body  12 . In this case, the boss  29  is not necessarily fixed. 
     In each of the embodiments described above, the ink tank  19 T may be configured to be mounted on the apparatus main body  12  (printing function unit  12 A) or the image reading unit  13  using the fixing member (for example, screws or adhesives). In addition, it is possible to make the mounting position be a position of right and left side wall portion or the back surface seen from the front side of the sub-scanning direction Y (front surface side). Alternately, the position may be the upper surface of the automatic manuscript supply device  14 . 
     In the printer  11  in the first to the fourth embodiments described above, the cover member disposed on the upper portion of the printing function unit  12 A may be a member that covers at least a part of the opening portion  12 K, without including the image reading unit  13  and the automatic manuscript supply device  14 . 
     Ninth Embodiment 
     As illustrated in  FIG. 19 , the printer  211  as the liquid ejecting apparatus in a ninth embodiment includes the apparatus main body  212  showing a substantially rectangular shape and an ink tank  219  as an example of the liquid containing unit showing a substantially rectangular shape as a separate body from the apparatus main body  212 . 
     In the apparatus main body  212  on the side where ink is supplied, in the lower side which is a gravity direction, the printing function unit  212 A as an example of the housing unit in which the printing unit  220  is embedded is disposed, and in the upper side which is an antigravity direction side, the image reading unit  213  in which the image reading mechanism such as a scanner which reads the manuscript (image) is disposed as an example of the cover member. The image reading unit  213  has a configuration so as to rotate (displacement) around the rotation axis  213   a  provided on one side end (rear side) of the apparatus main body  212 , and such that the side end of the opposite side (front side) to the rotation axis  213   a  in the apparatus main body  212  is lifted. That is, in the housing side surface (both side surface of the right and left) of the image reading unit  213 , the hand grip portion  213 T is concavely provided, and the user of the printer  211  can lift the image reading unit  213  by inserting the hand into the hand grip portion  213 T, at the time of maintenance, for example. By the lifting, the opening portion  212 K (refer to  FIG. 20A ) is exposed, which is provided on the upper portion of the printing unit  220  and causes at least a part of the movement region of the carriage  221  which is disposed to reciprocate in the printing function unit  212 A to be exposed. 
     Furthermore, the automatic manuscript supply device  214  which automatically supplies the read manuscript with respect to the image reading unit  213  is disposed on the upper portion of the image reading unit  213 . The automatic manuscript supply device  214  has a configuration so as to rotate (displacement) around the rotation axis  214   a  provided on one side end (rear side) of the apparatus main body  212 , and such that the side end of the opposite side (front side) to the rotation axis  214   a  in the apparatus main body  212  is lifted. By the lifting of the automatic manuscript supply device  214 , the user can manually supply the read manuscript with respect to the image reading unit  213 . 
     In addition, on the rear side of the apparatus main body  212 , the loading table  215  capable of repeatedly loading a plurality of sheets P is provided. The sheet P loaded on the loading table  215  is transported one by one to the printing unit  220  provided on the printing function unit  212 A in a direction from the rear to the front, and the printing is performed with respect to the sheet P in the printing unit  220 . That is, the sheet P is transported from the loading table  215  to the printing unit  220  by a not illustrated transportation mechanism, the image is printed by ejecting the ink on the sheet P from the liquid ejecting head  222  which reciprocates by the moving mechanism which is not illustrated along the direction (called as main scanning direction X) crossing the transportation direction (called as sub-scanning direction Y) of the sheet P in the printing unit  220 . The sheet P on which the image is printed by the printing unit  220  is further transported to the front (sub-scanning direction Y) from the printing unit  220 , to be discharged from the sheet discharge port  216  provided on the front surface of the apparatus main body  212  (printing function unit  212 A). 
     On the lower side of the discharge port  216  in the apparatus main body  212  (printing function unit  212 A), the tray accommodation unit  212 H is configured, in which the stacker  217  is accommodated as an example of a discharge tray that receives the sheet P discharged from the sheet discharge port  216 , by the housing portion protruded to be formed in a discharging direction of the sheet P (here, the sub-scanning direction Y). By the protrusion, the stacker  217  can easily be pulled out from the apparatus main body  212  by the grip portion  217   a . Thus, the stacker  217  is pulled out from the apparatus main body  212  depending on the length in a discharge direction of the sheet P (transportation direction). 
     On the other hand, on the upper side of the sheet discharge port  216  in the apparatus main body  212  (printing function unit  212 A), the operation panel unit  218  for causing the printing operation to be performed in the printing unit  220  is provided. The operation panel unit  218  is configured to have the housing portion showing the inclined surface in which the lower side of the operation panel unit is protruded to the discharge direction side of the sheet P than the upper side. In the inclined surface, the operation member for operating at the time of performing the printing are prepared, such as the display unit  218   a  for displaying the menu screen (for example, liquid crystal display) or an operation button  218   b  like a power button. Thus, the operation by the user can easily be performed. 
     Now, the printing unit  220  included in the printer  211  in the embodiment includes a carriage  221  as a moving body which reciprocates in the main scanning direction X, and the liquid ejecting head  222  which ejects the ink in the carriage  221  is included. The carriage  221  is guided by a guide frame  230  which is a plate member extended along the main scanning direction X, and is provided so as to be movable (reciprocately movable) in the main scanning direction X. That is, the guide frame  230  has a rail portion  231  in which an upper rail  231 A and a lower rail  231 B are provided by the member being bent in substantially U-shape in the both side end portion of the upper and lower portion of the plate member which is perpendicular to the main scanning direction X. The rear end side of the carriage  221  is supported by the upper rail  231 A and the lower rail  231 B, and guided to the upper rail  231 A and the lower rail  231 B in a cantilevered state, and reciprocates on the rail portion  231  along the main scanning direction X. Then, from the liquid ejecting head  222  included in the reciprocately moving carriage  221 , the ink supplied by the ink supply tubes  240  is ejected, and the printing with respect to the sheet P is performed. 
     In the printer  211  in the embodiment, a relay adapter AD which relays the ink supplied via the ink supply tubes  240  to the liquid ejecting head  222  is mounted in the carriage  221 , the ink is supplied to the liquid ejecting head  222  from the mounted relay adapter AD. Therefore, the ink supply tubes  240  forms a flow path of the ink such that the ink can flow between the ink tank  219  and the liquid ejecting head  222 , by connecting the ink supply tubes  240  which supplies the ink from the ink tank  219  in a state that the ink is contained, to the relay adapter AD. 
     Here, it is assumed that one type of ink (for example, a black ink) is supplied from the ink tank  219 , and one type of relay adapter AD corresponding to such one type of ink is mounted on the carriage  221 . Of course, in a case where a plural types of ink is supplied from the ink tank  219 , the plural number of relay adapters AD depending on the number of types (maximum four in  FIG. 19 ) are mounted. 
     Next, the configuration of the fixing portion that fixes the ink supply tubes  240  in the ninth embodiment will be described with reference to  FIGS. 20A and 20B ,  FIG. 21 , and  FIG. 22 . The fixing portion in the ninth embodiment has a configuration in which the ink supply tubes  240  are fixed by the fixing tool with respect to the housing member forming the opening portion  212 K. A variety of members such as a string, a rubber band, a clip, an adhesive tape, and adhesive can be used as the fixing tool. Incidentally, the embodiment will be described as a case using the adhesive tape. In addition, in describing  FIGS. 20A and 20B ,  FIG. 21 , and  FIG. 22 , the same configuration members as  FIG. 19  will be referenced by the same numerals, and the descriptions thereof will not be repeated. In addition,  FIG. 21  is illustrated in a state in which the image reading unit  213  and the automatic manuscript supply device  214  are removed. 
     As illustrated in  FIG. 20A , the ink tank  219  which contains the ink ejected from the liquid ejecting head  222  is disposed outside the right housing when viewed from the front side of the sub-scanning direction Y with respect to the apparatus main body  212 . That is, the ink tank  219  is disposed on the position close to the home position HP in the main scanning direction X which is the outer side of the movement region of the carriage  221 . Then, one end side of the ink supply tubes  240  which functions as the flow path of the ink contained in the ink tank  219 , is connected to the ink tank  219 . In addition, another end side of the ink supply tubes  240  is inserted, from the position close to the home position HP in the main scanning direction X of the carriage  221 , into movement region of the carriage  221  exposed through the opening portion  212 K provided on the printing function unit  212 A, and connected to the relay adapter AD mounted on the carriage  221 . 
     In addition, on the upper surface of the printing function unit  212 A, in a case where the side which rotatably fixes the image reading unit  213  is the rear side, to the front side of the opening portion  212 K, on the position corresponding to the projection unit  213   b  and  213   c  protruding on the printing function unit  212 A in the oscillation direction of the image reading unit  213 , the concave-shaped portion  212   b  and  212   c  are formed. The concave-shaped portion  212   b  is provided as a housing member forming the opening portion  212 K, the boss  229  having a substantially cylindrical shape is fixed upward with a predetermined length in the concave-shaped portion  212   b . That is, in a case where the image reading unit  213  is rotating in a direction closing the opening portion  212 K of the printing function unit  212 A, by being interposed between the concave-shaped portion  212   b  and the image reading unit  213 , the boss  229  is provided so as to secure a void to be inserted through the ink supply tubes  240  between the image reading unit  213  and the opening portion  212 K of the printing function unit  212 A. 
     In the upper surface of the printing function unit  212 A, the concave-shaped portion  212   b  is provided on both end portions in the main scanning direction X respectively, the boss  229  is fixed to at least one end, that is, to the right side when viewed from the front side of the sub-scanning direction Y in  FIG. 20A  and  FIG. 20B . Of course, in order to stably form the void, as illustrated in  FIG. 20A  by the two-dot chain line, it may preferable to fix the boss  229  to the left side of the concave-shaped portion  212   b  when viewed from the front side of the sub-scanning line Y. 
     Now, The middle part in a longitudinal direction of the ink supply tubes  240  which is inserted through the void formed by the boss  229  in this manner, and inserted into the apparatus main body  212  is fixed to the housing member of the printing function unit  212 A by the adhesive tape. In the embodiment, the description is made as an example of being fixed using three adhesive tapes. Of course, the necessary number of adhesive tapes is used in fixing the ink supply tubes  240 . 
     Specifically, the ink supply tubes  240 , firstly in the housing member of the concave-shaped portion  212   b , is fixed by the pasted first adhesive tape  261 . Next, the middle part in the longitudinal direction of the ink supply tubes  240  is fixed sequentially, by the second adhesive tape  262  and the third adhesive tape  263  to which the connected side of the ink supply tubes  240  to the relay adapter AD is pasted to the lower portion of the opening portion  212 K. Hereinafter, in the description below, in a case where the first to third adhesive tapes  261  to  263  are distinguished, the adhesive tapes will be simply called adhesive tape  260 . 
     In the middle part of the ink supply tubes  240  fixed by the adhesive tape  260 , by the adhesive tape  260  being abutting the outer surface of the ink supply tubes  240 , the ink supply tubes  240  are fixed in a state where moving in a length direction and in a direction crossing the length direction is regulated. Therefore, the middle part of the ink supply tubes  240  fixed by the adhesive tape  260  functions as an example of the fixing portion. 
     Then, in the embodiment, the middle part of the ink supply tubes  240  fixed by the third adhesive tape  263  is the fixing portion that relatively immovably fixes a portion of the ink supply tubes  240  in the length direction with respect to the opening portion  212 K, that is, the fixing portion by the third adhesive tape  263 . As a result, a portion between the third adhesive tape  263  in the length direction of the ink supply tubes  240  and the relay adapter AD, has a curved shape which is curved in the substantially vertical direction as illustrated in  FIG. 20A  and  FIG. 20B , and becomes a deformable moving unit  240 H which performs a follow-up deformation along a movement of the carriage  221 . In other words, The length of the tubes of the deformable moving unit  240 H is regulated by the fixed position of the third adhesive tape  263 . Then, in the embodiment, the fixing portion by the third adhesive tape  263  is provided on the substantially center part of the movement region of the carriage  221  in the main scanning direction X, the ink supply tubes  240  have the substantially same length in both sides of moving range of the carriage  221  having a fixing portion as the center. 
     Incidentally, as illustrated in  FIG. 20B , in the embodiment, the ink supply tubes  240  may have a configuration in which a plurality of tubes are connected via the joint  240 C that links between the tubes in the length direction thereof. The joint  240 C is provided on a plurality of positions depending on the number of tubes linked between the ink tank  219  and the carriage  221 , and causes the ink to flow through the linked tubes. Incidentally, in the embodiment, as illustrated in  FIG. 20B  as an example, the joint  240 C has a through-hole portion, and has a structure in which the cylindrical shape portion to which the tubes are inserted are formed. A seam in which two tubes are linked via the joint  240  is formed in a location in the deformable moving unit  240 H of the ink supply tubes  240  as illustrated in  FIG. 20A . 
     Next, as illustrated in  FIG. 21 , in the present embodiment, a fixing portion may be configured by pasting the third adhesive tape  263  which fixes the ink supply tubes  240  to the inner side surface of the housing member which forms the opening portion  212 K. Specifically, in the front side (rear side) of the operation panel unit  218  which is the front side (front side) in the sub-scanning direction Y of the printing function unit  212 A, the position determination member  251  that determines the position of the image reading unit  213  with respect to the printing function unit  212 A is fixed on the horizontal surface by the fixing screws  255 . An inner side surface  212 N which falls to the direction of gravity from the end portion of the opening portion  212 K side in the horizontal surface on which the position determination member  251  is fixed. The ink supply tubes  240  are fixed to the inner side surface  212 N by the third adhesive tape  263 . 
     Therefore, in the configuration of the fixing portion illustrated in  FIG. 20A  and  FIG. 20B , the deformable moving unit  240 H of the ink supply tubes  240  has a curved shape which is curved along the substantially vertical direction. However, in the configuration of the fixing portion illustrated in  FIG. 21 , the deformable moving unit  240 H of the ink supply tubes  240  has a curved shape which is curved along the substantially horizontal direction. In the configuration of the fixing portion illustrated in  FIG. 21 , the third adhesive tape  263  is pasted on the position corresponding to the substantially center part in the movement region of the carriage  221 . In addition, the second adhesive tape  262  may be pasted as is necessary, which is not illustrated in  FIG. 21 . In addition, a joint  240 C of the ink supply tubes  240  is provided, as necessary. 
     Alternately, as illustrated in  FIG. 22 , the fixing portion may be configured by pasting the third adhesive tape  263  which fixes the ink supply tubes  240  to the housing member positioned on the front side (back side) of the sub-scanning direction Y to the opening portion  212 K, among the housing members forming the opening portion  212 K. 
     That is, the ink supply tubes  240  are fixed by the first adhesive tape  261  which is pasted with respect to the housing member of the concave-shaped portion  212   c  which is positioned in the back side to the opening portion  212 K. Next, the connection side of the ink supply tubes  240  to the relay adapter AD is fixed by the third adhesive tape  263  which is pasted on the upper surface thereof, with respect to the backside member  212   d  which forms the opening portion  212 K. In the configuration of the fixing portion, the third adhesive tape  263  is pasted on the position corresponding to the substantially center part of the movement region of the carriage  221 , in the main scanning direction X. In addition, even if not illustrated, the second adhesive tape  262  is also pasted, as necessary. 
     As a result, the deformable moving unit  240 H formed on the part between the third adhesive tape  263  and the relay adapter AD in the length direction of the ink supply tubes  240 , has a curved shape which is comparatively largely curved in the substantially horizontal direction as illustrated in  FIG. 22 . The joint  240 C of the ink supply tubes  240  is provided, in the deformable moving unit  240 H as necessary, which is not illustrated in  FIG. 22 . 
     Next, the action of the printer  211  in the ninth embodiment will be described. 
     In the printer  211 , by fixing the ink supply tubes  240  to the housing member forming the opening portion  212 K by the adhesive tape  260 , it is possible to easily form the fixing portion. In addition, by adjusting the paste position of the third adhesive tape  263 , it is possible to change the curved shape of the deformable moving unit  240 H which performs a follow-up deformation along the movement of the carriage  221 . 
     Furthermore, in a case where the ink supply tubes  240  is removed from the apparatus main body  212  in order to perform the maintenance of the ink supply tubes  240 , it is possible to easily remove the ink supply tubes  240  from the apparatus main body  212  by peeling off the adhesive tape  260 . 
     In addition, it is possible to easily fix the ink supply tubes  240  to the printing function unit  212 A which is largely exposed, in a state where the image reading unit  213  opens the opening portion  212 K of the apparatus main body  212  (printing function unit  212 A). 
     Tenth Embodiment 
     Next, the configuration of the fixing portion which fixes the ink supply tubes  240  in the tenth embodiment will be described with reference to  FIG. 23  and  FIG. 24 . The fixing portion in the tenth embodiment includes a support member which can be displaced between the first position where the support member is disposed so as to cross the opening portion  212 K and the second position where the support member is disposed so as to be spaced away farther from the center position of the opening portion  212 K than from the first position as a housing member of the apparatus main body  212  (printing function unit  212 A). Then, the fixing portion of the ink supply tubes  240  has a configuration to be provided on the support member of the fixing portion. In the description in  FIG. 23  and  FIG. 24 , the same configuration members as the ninth embodiment and  FIG. 19  are referenced by the same numerals, and the description thereof will not be repeated. In addition, the joint  240 C of the ink supply tubes  240  is not illustrated in  FIG. 23  and  FIG. 24 . 
     As illustrated in  FIG. 23 , in the upper surface of the printing function unit  212 A, the position determination member  251  is fixed, which is fixed on the front side (rear side) of the operation panel unit  218  that is the forward side (front side) of the sub-scanning direction Y, and the rectangular plate shaped support member  270  is rotatably fixed with one end thereof interposed with the position determination member  251 . That is, in the support member  270 , fixing screws  255  are inserted with respect to the through-hole (not illustrated) as a rotation axis formed on one end side of the longitudinal direction of the support member  270  forming the rectangular plate shape. For this reason, the support member  270  is rotatably (oscillation) mounted with the through-hole as a rotation axis, and the position can be changed by the rotation. 
     In the present embodiment, in the substantially center part in the longitudinal direction of the support member  270 , by a part of the ink supply tubes  240  being fixed by the fixing tool  226 , the fixing tool is configured, in which the middle part in the length direction of the ink supply tubes  240  is fixed to the substantially center part of the support member  270 . In the present embodiment, the adhesive tape  260  (the third adhesive tape  263 ) can be used as the fixing tool  226  as similar to the ninth embodiment. Alternately, the fixing member having a locking hook that can be locked to the locking hole (not illustrated) provided on the support member  270  may be used as a fixing tool  226 . By the fixing tool  226  like this, a part of the ink supply tubes  240  in the length direction is fixed with respect to the support member  270 , by fixing the ink supply tubes  240  to the support member  270  in a state where the ink supply tubes  240  are interposed between the support member  270 . As a result, a part of the ink supply tubes  240  in the length direction between the fixing tool  226  and the relay adapter AD is formed as the deformable moving unit  240 H which performs a follow-up deformation along the movement of the carriage  221 . For example, by interposing the friction plate formed of rubber in the part where the support member  270  and the position determination member  251  are overlapping, it may be configured to suppress the inadvertent oscillation. 
     Next, the action of the printer  211  in the tenth embodiment will be described with reference to  FIG. 23  and  FIG. 24 . 
     As illustrated in  FIG. 23 , in the printer  211  of the present embodiment, when the recording is performed, by the support member  270  disposed so as to cross the opening portion  212 K of the printing function unit  212 A, the ink supply tubes  240  are fixed on the upper side of the moving carriage  221 . In other words, the support member  270  is disposed on the position where the reciprocated movement to the main scanning direction X of the carriage  221  is not interrupted (here, the upper position). In addition, the ink supply tubes  240  fixed by the support member  270  is disposed showing a curved shape which is curved toward the moving direction (left side) of the carriage  221  in the lower side of the support member  270 . 
     By disposing the ink supply tubes  240  in this manner, the curved section portion thereof, at the time of performing the recording, functions as the deformable moving unit  240 H which performs a follow-up deformation along the movement of the carriage  221  to the main scanning direction X. That is, as illustrated in  FIG. 23  by a two-dot chain line, the deformable moving unit  240 H of the ink supply tubes  240  of which one end side is connected to the relay adapter AD mounted on the carriage  221  can easily change the position in the region of the opening portion  212 K of the printing function unit  212 A. 
     It is preferable that the support member  270  has a configuration in which the position disposed so as to cross the opening portion  212 K may be held as possible. For example, as illustrated in  FIG. 23 , an end portion opposite to one end side which is the center of rotation (oscillation) in the longitudinal direction thereof may be fixed with respect to the housing member forming the opening portion  212 K by the adhesive tape  260  as an example of the fixing tool. 
     Here, in the printer  211 , in a case where the recording operation is stopped to lead to a non-recording time due to the jammed state of the sheet during the transportation, the user causes the support member  270  to rotate (oscillate) using the through-hole as a center of rotation in a direction farther from the center position of the opening portion  212 K of the printing function unit  212 A. 
     That is, as illustrated in  FIG. 24 , the user peels off the adhesive tape  260 , and causes the support member  270  to change the position from the first position where the opening portion  212 K of the printing function unit  212 A is blocked to the second position where the opening portion  212 K is not blocked. In this way, the user can easily insert the finger (hand) into the movement region of the carriage  221  through the opening portion  212 K of the printing function unit  212 A, and the sheet in the jammed state can easily be removed. 
     At this time, the frictional resistance in the oscillation direction when the support member  270  is oscillating acts to the support member  270  by the friction plate interposed between the position determination member  251 . For this reason, when the user inserts the finger into the carriage  221  through the opening portion  212 K of the printing function unit  212 A, even in a case where the user removes the hand from the support member  270  which changes the position to the second position, the changed position of the support member  270  is stably held by the frictional resistance acting by the friction plate. Furthermore, in order to stably hold the support member  270  on the changed position (the second position), as illustrated in  FIG. 24 , the end portion opposite to one end side which is the center of the oscillation in the longitudinal direction of the support member  270  may be fixed to the printing function unit  212 A (here, concave-shaped portion  212   b ) by the adhesive tape  260 . 
     After removing the sheet in the jammed state, the user causes the support member  270  to change the position to the first position which crosses the opening portion  212 K of the printing function unit  212 A. Then, the end portion opposite to one end side which is the center of the oscillation in the longitudinal direction of the support member  270  is fixed with respect to the housing member in the back side which forms the opening portion  212 K by the adhesive tape  260  again. 
     In the above-mentioned ninth embodiment, when the image reading unit  213  rotates (oscillation) in a state of closing the opening portion  212 K of the printing function unit  212 A, in a case where the projection unit  213   b  and  213   c  projecting to the printing function unit  212 A in the swinging direction of the image reading unit  213 , it is preferable that the ink supply tubes  240  be disposed at an avoidance position which is not crushed by the projection units  213   b  and  213   c.    
     For example, as illustrated by a solid line or a double dashed line in  FIG. 25 , when the ink supply tubes  240  are fixed by the adhesive tape  260  in the concave-shaped portion  212   b  or a concave-shaped portion  212   c , the ink supply tubes  240  fixes the first adhesive tape  261  and the second adhesive tape  262  according to an angle at which the ink supply tubes  240  are formed at a concave-shaped portion  212   b  or at an end corner of the bottom surface of the concave-shaped portion  212   c . The ink supply tubes  240  disposed at this angle have a high probability to avoid being crushed by the image reading unit  213  (projection unit  213   b  and  213   c ). 
     That is, the corners of the projection units  213   b  and  213   c  of the image reading unit  213  are formed to be round to be safe even at a user&#39;s contact. Therefore, in the concave-shaped portions  212   b  and  212   c , in corners (corners) rather than the bottom surface portion, it is easy to form a relatively large void between the printing function unit  212 A and the image reading unit  213 . In  FIG. 25 , a joint  240 C of the ink supply tubes  240  provided as needed is not illustrated. 
     In the above-mentioned ninth embodiment and the tenth embodiment, the ink supply tubes  240  are described as it is one. However, when a plurality of ink tanks  219  are included in the printer  211 , a configuration in which an ink is supplied to the liquid ejecting head  222  side through each of the ink supply tubes  240  from the ink tank  219  side may be provided. As an example, in the tenth embodiment configuring the fixing portion of the ink supply tubes  240  by the support member  270 , a case where a plurality of ink supply tubes  240  are arranged will be described referring to  FIG. 26 . 
     As illustrated in  FIG. 26 , a plurality (here, three) of ink supply tubes  240  are fixed to the support member  270  by the fixing tool  226  in a parallel state along a plane of the support member  270 . The ink supply tubes  240  are fixed in a parallel state along the plane of the support member  270 , and accordingly a curved portion formed on the lower side of the support member  270 , that is, the deformable moving unit  240 H is easily formed following the movement of the carriage  221 . The plurality of ink supply tubes  240  can be configured to have tubes connected in parallel with each other, or can be configured to have an individually separated individual tube. 
     According to the above-mentioned embodiment, the following effects are obtained. 
     By including the ink supply tubes  240  as much as the number of the ink tanks  219 , it is possible to supply an ink to the liquid ejecting head  222  from each ink tank  219 . 
     In the above-mentioned ninth embodiment, a configuration where an additional housing member is attached in addition to the housing member to form the opening portion  212 K of the printing function unit  212 A, and the ink supply tubes  240  are fixed to the additional housing member may be provided. An example of the configuration will be described referring to  FIG. 27 . 
     As illustrated in  FIG. 27 , an auxiliary fixing plate  266  formed of a plate shape member as an additional housing member is interposed between the position determination member  251  and the upper surface of the printing function unit  212 A to fix a screw, and with respect to the fixed auxiliary fixing plate  266 , the ink supply tubes  240  are fixed by pasting adhesive tape  260  (the third adhesive tape  263 ). The auxiliary fixing plate  266  is fixed to be spaced away from the movement region of the carriage  221  in the horizontal direction, and the image reading unit  213  in a state of closing the opening portion  212 K is fixed to be spaced away from the bottom side along with the fixed ink supply tubes  240  in a vertical direction. In the embodiment, the fixed ink supply tubes  240  have a shape bent in a substantially C-shape which is concaved on the bottom side so as to be spaced away from the image reading unit  213  (projection unit  213   b ). 
     The auxiliary fixing plate  266  may be a flat plate without bending, and there is no problem even if the auxiliary fixing plate  266  is fixed to another position along the main scanning direction X, not a position of the position determination member  251 . In addition, when the ink supply tubes  240  are restricted to move to the longitudinal direction and a direction intersecting with the longitudinal direction, the auxiliary fixing plate  266  functions as an example of the fixing tool, so that the third adhesive tape  263  does not need to be pasted. 
     In the ninth embodiment and the tenth embodiment, the other end side of the ink supply tubes  240  may be configured to be inserted from the outside of the housing at the left side seen from the front side of the sub-scanning direction Y, that is, an opposite and close position to the home position HP in the main scanning direction X of the carriage  221  to the opening portion  212 K. 
     In the above-mentioned embodiment, the ink tanks  19 T and  219 T as a liquid containing unit are a type which may be refilled, that is, provides an inlet in the ink tanks  19 T and  219 T. After consuming an ink in the ink tanks  19 T and  219 T, a configuration in which an ink may be injected from the inlet may be provided, a pack may be exchanged, that is, a bag-like container where an ink is contained is included in the ink tanks  19 T and  219 T, and when an ink is consumed, the bag-like container may be exchanged. In addition, the ink tanks  19 T and  219 T may be fixed to the apparatus main bodies  12  and  212 , and the apparatus main bodies  12  and  212  may be configured as an additional body, respectively. 
     An ink contained in the ink tanks  19 T and  219 T may be a single color only. For example, when printing text characters, black color ink is largely consumed, so that the ink tanks  19 T and  219 T may contain a black color ink only. 
     In the above-mentioned embodiment, a target is not limited to a sheet, and fabric, a resin film, a resin sheet, a metal sheet, and the like may be adapted. 
     In the above-mentioned embodiment, the printers  11 ,  11 A, and  211  may be a liquid ejecting apparatus that ejects or discharges a liquid other than an ink. As a state of liquid discharged from the liquid ejecting apparatus to be a small amount of droplet, those pulling a trail in a granular-shape, a teardrop-shape, a filament-shape are included. In addition, a liquid herein may be any material which may be ejected from the liquid ejecting apparatus. For example, the material may be one in a liquid state, or a fluid-like material such as a liquid with high or low viscosity, sol, gel water, other inorganic or organic solvents, solutions, a liquid resin, a liquid metal (metal melt). In addition, the material intends to include not only a liquid but also those in which particles of a functional material formed of solid matter such as pigment or metal particles are dissolved in a solvent, dispersed or mixed. A typical example of the liquid includes the ink as described in the above-mentioned embodiment, a liquid crystal, and the like. Here, the ink includes a general water-based ink and an oil-based ink, and various types of liquid composition such as gel ink, hot-melt ink, and the like. A specific example of the liquid ejecting apparatus is a liquid ejecting apparatus ejecting a liquid containing materials dispersed or dissolved therein such as an electrode material or a color material used in manufacturing, for example, a liquid crystal display, an electroluminesence (EL) display, a surface emitting display, and a color filter. 
     In addition, a liquid ejecting apparatus for ejecting a living organic material used in manufacturing a biochip, a liquid ejecting apparatus ejecting a liquid which is a sample used as a precision pipette, a printing device, a microdispenser, and the like may be included. Furthermore, there are also a liquid ejecting apparatus ejecting a lubricant at a pinpoint to a precision machine such as a watch or a camera, and a liquid ejecting apparatus ejecting a transparent resin liquid such as a UV-curing resin in order to form a micro hemispherical lens (optical lens) used in an optical communication element. In addition, a liquid ejecting apparatus is also included which ejects an etching liquid such as acid or alkali to perform etching on a substrate and the like.
