     DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Embodiments of a liquid ejecting apparatus will be described below with reference to the drawings. The liquid ejecting apparatus is, for example, an ink jet printer that prints an image such as a character or a photograph on a medium such as a sheet of paper by ejecting ink as an example of liquid. 
     First Embodiment 
     As illustrated in  FIG. 1 , a liquid ejecting apparatus  11  includes a housing  12 , a cassette  13  that can contain media  99 , and a support table  14  that can support the media  99 . The liquid ejecting apparatus  11  also includes a liquid ejecting head  15  that can eject liquid, a supply channel  16  for supplying the liquid to the liquid ejecting head  15 , a mounting unit  18  in which liquid containers  17  are removably mounted, and a controller  19 . The cassette  13 , the support table  14 , the liquid ejecting head  15 , the supply channel  16 , the mounting unit  18 , and the controller  19  are disposed in the housing  12 . The controller  19  collectively controls the liquid ejecting apparatus  11 . 
     The cassette  13  is removably mounted in the housing  12 . The cassette  13  is mounted by being moved in the depth direction Y and removed from the mounting unit  18  by being moved in the opposite direction to the depth direction Y. The depth direction Y refers to a direction directed, for example, from a front surface to a rear surface of the liquid ejecting apparatus  11 . Thus, the cassette  13  according to the present embodiment is mounted through/removed from the front surface of the liquid ejecting apparatus  11 . The media  99  contained in the cassette  13  are transported in the housing  12  by rollers (not illustrated) disposed in the housing  12 . 
     The support table  14  is positioned above the cassette  13 . The support table  14  supports, for example, the each of the media  99  transported from the cassette  13 . The liquid ejecting head  15  is positioned above the support table  14 . The liquid ejecting head  15  is held by a carriage  21  that reciprocates in the width direction X in the housing  12 . The width direction X is different from the depth direction Y or the direction of gravity Z. The carriage  21  is supported by a guide shaft  22  extending in the width direction X in the housing  12 . The guide shaft  22  guides the movement of the carriage  21 . 
     The liquid ejecting head  15  includes nozzles  23  from which the liquid can be ejected. The liquid ejecting head  15  ejects the liquid from the nozzles  23  to the medium  99  supported by the support table  14  when the liquid ejecting head  15  is moved together with the carriage  21 . In this way, the liquid ejecting head  15  performs printing on the medium  99 . 
     The mounting unit  18  is positioned below the cassette  13 . The liquid containers  17  can contain the liquid. The mounting unit  18  includes connecting portions  25  connectable to the liquid containers  17  mounted in the mounting unit  18 . The liquid contained in the liquid containers  17  can be supplied through the connecting portions  25 . That is, the liquid can be supplied from the liquid containers  17  to the liquid ejecting head  15  through the connecting portions  25 . 
     The liquid containers  17  contain the liquid to be supplied to the liquid ejecting head  15 . The liquid containers  17  are mounted in the mounting unit  18  by being moved in the depth direction Y and removed from the mounting unit  18  by being moved in the opposite direction to the depth direction Y. The liquid containers  17  according to the present embodiment are, as is the case with the cassette  13 , mounted through/removed from the front surface of the liquid ejecting apparatus  11 . 
     A plurality of the liquid containers  17  can be mounted in the mounting unit  18  so as to overlap in the up-down direction. The mounting unit  18  according to the present embodiment allows the plurality of liquid containers  17  to be mounted therein on two stages, that is, on an upper stage and a lower stage. The mounting unit  18  may allow the plurality of liquid containers  17  to be mounted therein on three or more stages. 
     Three liquid containers  17  are arranged in the width direction X on the lower stage of the mounting unit  18 . One of the liquid containers  17  having a larger capacity than three other liquid containers  17  is mounted on the upper stage of the mounting unit  18 . This large-capacity liquid container  17  has a larger length than that of the other liquid containers  17  in the width direction X. 
     The plurality of liquid containers  17  respectively contain different types of the liquid. According to the present embodiment, the large-capacity liquid container  17  contains black ink that is used frequently. The other three liquid containers  17  contain, for example, color ink such as cyan ink, magenta ink, and yellow ink. According to the present embodiment, the liquid containers  17  positioned on the lower stage of the mounting unit  18  may be referred to as “lower liquid containers  17   a ”, and the liquid container  17  positioned on the upper stage of the mounting unit  18  may be referred to as “upper liquid container  17   b ”. That is, in the mounting unit  18 , the lower liquid containers  17   a  and the upper liquid container  17   b  are arranged in the direction of gravity Z. 
     The supply channel  16  allows the liquid to be supplied therethrough from the liquid containers  17  mounted in the mounting unit  18  to the liquid ejecting head  15 . The supply channel  16  includes first channel forming members  27 , second channel forming members  28 , and a coupling member  29  that connects the first channel forming members  27  and the respective second channel forming members  28  to one another. 
     The first channel forming members  27  connect the mounting unit  18  and the coupling member  29  to each another. The second channel forming members  28  connect the coupling member  29  and the liquid ejecting head  15  to each other. The first and second channel forming members  27 ,  28  are, for example, bendable tubes. The numbers of a plurality of the first channel forming members  27  and a plurality of the second channel forming members  28  to be provided correspond to the number of the liquid containers  17  able to be mounted in the mounting unit  18 . The coupling member  29  is connected to the plurality of first channel forming members  27  and the plurality of second channel forming members  28 . 
     As illustrated in  FIG. 2 , the mounting unit  18  includes a frame member  30 , a separator  40 , and connecting units  50 . The frame member  30  is formed of, for example, a metal sheet and mounted on an inner bottom portion of the housing  12 . Since the frame member  30  is formed of a metal sheet, the rigidity of the housing  12  is improved. The frame member  30  supports the liquid containers  17  mounted in the mounting unit  18 . The liquid containers  17  mounted in the mounting unit  18  are positioned above the frame member  30 . 
     The separator  40  is a plate-shape member formed of, for example, resin. Since the separator  40  is formed of resin, the weight of the mounting unit  18  is reduced. The separator  40  is mounted on the frame member  30 . A space in which the liquid containers  17  are mounted is separated in the up-down direction by mounting the separator  40  on the frame member  30 . That is, in the mounting unit  18 , a space below the separator  40  allows the lower liquid containers  17   a  to be mounted therein. Thus, the lower liquid containers  17   a  are disposed on the frame member  30  such that the lower liquid containers  17   a  are interposed between the frame member  30  and the separator  40 . In the mounting unit  18 , a space above the separator  40  allows the upper liquid container  17   b  to be mounted therein. The upper-stage liquid container  17   b  is disposed on the separator  40 . 
     The separator  40  separates, in the up-down direction, the space where the plurality of liquid containers  17  mounted in the mounting unit  18  are mounted. When the mounting unit  18  allows the liquid containers  17  to be separately mounted on three or more stages, a plurality of separators  40  are provided. 
     The connecting units  50  are connected to the liquid containers  17  mounted in the mounting unit  18 . The connecting portions  25  are parts of elements of the connecting units  50 . The connecting units  50  are disposed near the rear portion in the depth direction Y. 
     The number of the connecting units  50  to be provided corresponds to the number of the liquid containers  17  able to be mounted. The mounting unit  18  according the present embodiment includes four connecting units  50 . Three of the connecting units  50  are mounted on the frame member  30  and one of the connecting units  50  is mounted on the separator  40 . According to the present embodiment, the connecting units  50  connected to the lower liquid containers  17   a  may be referred to as “lower connecting units  50   a ”, and the connecting unit  50  connected to the upper liquid container  17   b  may be referred to as “upper connecting unit  50   b ”. The lower connecting units  50   a  mounted on the frame member  30  are arranged in the width direction X. The upper connecting unit  50   b  is mounted at a central position of the separator  40  in the width direction X. 
     Each of the connecting units  50  is connected to one end of a corresponding one of the first channel forming members  27 . Thus, when the liquid container  17  is connected to a corresponding one of the connecting portion  25 , the liquid contained in the liquid container  17  flows into the supply channel  16  through the connecting units  50 . 
     There may be leakage of the liquid through joints where the members are connected to one another between the liquid containers  17  mounted in the mounting unit  18  and the liquid ejecting head  15 . For example, the connecting portions  25  are the joints where the liquid containers  17  are connected to the respective connecting units  50 . The liquid is highly likely to leak through the connecting portions  25  while the liquid containers  17  are being mounted in/removed from the mounting unit  18 . 
     The supply channel  16 , which includes a plurality of members, has the joints. For example, in the supply channel  16 , portions where the first channel forming members  27  and the coupling member  29  are connected to one another and portions where the coupling member  29  and the second channel forming members  28  are connected to one another are the joints. 
     The connecting units  50 , which each include a plurality of members, have the joints as is the case with the supply channel  16 . Each of the connecting units  50  includes, for example, a check valve, a diaphragm pump, a buffer, and so forth in addition to the connecting portion  25 . The check valve suppresses flowing of the liquid from the connecting unit  50  to the liquid container  17 . The diaphragm pump sucks and discharges the liquid contained in the liquid containers  17 . The buffer stores the liquid supplied from the liquid container  17 . Portions where these members are connected to one another are the joints in the connecting unit  50 . 
     When the liquid leaks through such joints, the liquid flows downward in the housing  12 . In order to address this, the liquid ejecting apparatus  11  includes in the inner bottom portion of the housing  12  a detection unit  60  that detects the liquid having leaked. 
     The detection unit  60  is provided on a bottom wall  12   a  of the housing  12  below the mounting unit  18 . The detection unit  60  is disposed near the rear portion in the depth direction Y on the bottom wall  12   a . The detection unit  60  includes detectors  61  and a guide portion  62 . Each of the detectors  61  is, for example, a sensor and electrically connected to the controller  19 . When the liquid adheres to the detector  61 , the liquid is detected by the detector  61 . Upon detection of the liquid, the detector  61  transmits a signal to the controller  19 . Thus, the controller  19  recognizes the leakage of the liquid. 
     The guide portion  62  guides the liquid having dropped to the bottom wall  12   a  of the housing  12  to the detectors  61 . The guide portion  62  has a detection portion  62   a  extending in the width direction X and extended portions  62   b  extending from both ends of the detection portion  62   a  in the opposite direction to the depth direction Y. The detectors  61  are disposed so as to be in contact with the detection portion  62   a  in the guide portion  62 . Thus, the detection portion  62   a  is the target of the detection performed by the detectors  61 . According to the present embodiment, a plurality of the detectors  61  are provided such that the detectors  61  are spaced from one another along the detection portion  62   a.    
     The guide portion  62  includes an absorbing member  63  that absorbs the liquid. The absorbing member  63  has, for example, a belt shape. When the extended portions  62   b  absorb the liquid, the absorbing member  63  guides, due to the absorbing force thereof, the liquid absorbed by the extended portions  62   b  from the extended portions  62   b  to the detection portion  62   a . When the liquid having been absorbed by the extended portions  62   b  permeates the detection portion  62   a , the detectors  61  detect the liquid. In this way, the detectors  61  detect the liquid having leaked. 
     The frame member  30  has holes  31  through which the liquid having leaked drops. The liquid having leaked to the frame member  30  drops to the bottom wall  12   a  of the housing  12  through the holes  31  and is detected by the detection unit  60 . 
     The frame member  30  has a collection groove  32  through which the liquid having leaked is collected. The collection groove  32  extends in the width direction X so that the liquid leaked to the frame member  30  is collected. The holes  31  are continuous with both ends of the collection groove  32  of the frame member  30 . Thus, the liquid collected through the collection groove  32  efficiently drops to the bottom wall  12   a  of the housing  12  through the holes  31 . 
     It is preferable that the holes  31  be superposed on part of the guide portion  62  when seen in the up-down direction. According to the present embodiment, the extended portions  62   b  of the guide portion  62  are positioned immediately below the holes  31 . In this way, the guide portion  62  guides the liquid having dropped from the holes  31  to the detectors  61 . Thus, the liquid having leaked can be quickly detected. 
     The separator  40  has a through portion  41  for dropping of the liquid having leaked. The through portion  41  is, for example, a hole that penetrates through the separator  40  in the up-down direction. That is, the through portion  41  allows the space where the lower liquid containers  17   a  are mounted and the space where the upper liquid container  17   b  is mounted to communicate therethrough. The liquid having leaked to the separator  40  drops to the frame member  30  or the bottom wall  12   a  of the housing  12  through this through portion  41 . The liquid having dropped to the frame member  30  drops to the bottom wall  12   a  of the housing  12  through the holes  31  of the frame member  30 . 
     As illustrated in  FIGS. 3 and 4 , the mounting unit  18  includes guide plates  71  that guide movements of the liquid containers  17  during mounting of the liquid containers  17 . The guide plates  71  are mounted on the frame member  30  and the separator  40 . Each of the guide plates  71  has a plurality of guide grooves  72  extending in the depth direction Y, thereby the movements of the liquid containers  17  are guided during mounting/removing of the liquid containers  17 . 
     The position of the through portion  41  corresponds to the position of the upper connecting unit  50   b . The through portion  41  is disposed in front of the upper connecting unit  50   b  in the depth direction Y. One of the first channel forming members  27  connected to one of three lower connecting units  50   a  at the center in the width direction X extends so as to pass through the through portion  41  of the separator  40 . That is, the through portion  41  according to the present embodiment also serves as a passage for routing the supply channel  16  in the housing  12 . 
     As illustrated in  FIG. 5 , the connecting units  50  each include the connecting portion  25 , guide rods  51 , and a connecting terminal  52 . The connecting portion  25  is, for example, a supply needle inserted into the liquid container  17  during mounting of the liquid container  17 . The connecting portion  25  extends in the opposite direction to the depth direction Y. 
     As is the case with the connecting portion  25 , the guide rods  51  extend in the opposite direction to the depth direction Y. Two guide rods  51  are provided in each of the connecting units  50  such that the connecting portion  25  is interposed between two guide rods  51  in the width direction X. During mounting of the liquid container  17 , the guide rods  51  are inserted into the liquid container  17 , thereby the movement of the liquid container  17  in the depth direction Y is guided. The liquid container  17  is stably connected to the connecting portion  25  by being guided by the guide rods  51 . 
     The connecting terminal  52  is disposed above the guide rods  51  and connected to the controller  19 . When the liquid container  17  is mounted, the connecting terminal  52  is electrically connected to a circuit substrate included in the liquid container  17 . Information such as the type, the remaining amount, and the date of manufacture of the liquid contained in the liquid container  17  is recorded in the circuit substrate of the liquid container  17 . When the circuit substrate is connected to the connecting terminal  52 , the controller  19  reads the information from/writes the information to the circuit substrate. That is, the connecting terminal  52  exemplifies one of electrical members that allow electricity to flow therethrough. 
     The mounting unit  18  may include a liquid-remaining-amount substrate in which the remaining amount of the liquid in the buffer of the connecting unit  50  is recorded. In this case, the controller  19  reads the information from/writes the information to the liquid-remaining-amount substrate so as to control the remaining amount of the liquid in the buffer. That is, the liquid-remaining-amount substrate exemplifies one of the electrical members that allow electricity to flow therethrough. 
     The electrical members allow electricity to path therethrough when the mounting unit  18  functions. Thus, the electrical members include other substrates, motors, sensors, and so forth in addition to the connecting terminal  52  and the liquid-remaining-amount substrate. 
     When leakage of the liquid occurs in the housing  12 , the liquid may adhere to the connecting terminals  52  or other electrical members, resulting in failures such as a contact failure and a failure in supplying power. Accordingly, it is not preferable that the liquid having leaked adhere to the connecting terminals  52  or the other electrical members. That is, it is preferable that the through portion  41  of the separator  40  be disposed so as not to allow the liquid to drop to the connecting terminals  52  positioned below the through portion  41 . 
     As illustrated in  FIG. 6 , the through portion  41  is positioned such that, when seen in the up-down direction, an edge portion  42  of the through portion  41  does not overlap with any of the connecting terminals  52  positioned below the through portion  41 . That is, the through portion  41  is positioned such that the edge portion  42  of the through portion  41  does not overlap with any of the connecting terminals  52  of the lower connecting units  50   a  when seen in the up-down direction. 
     When the liquid leaks to the separator  40 , the liquid drops so as to flow along the edge portion  42  of the through portion  41 . Thus, by disposing the edge portion  42  of the through portion  41  at a different position from the position of any of the connecting terminals  52  of the lower connecting units  50   a  when seen in the direction of gravity Z, that is, the up-down direction, the likelihood of the liquid that drops through the through portion  41  adhering to any of the connecting terminals  52  of the lower connecting units  50   a  is reduced. The through portion  41  according to the present embodiment is positioned such that, when seen in the up-down direction, the through portion  41  does not overlap with any of the connecting terminals  52  positioned below the through portion  41 . 
     As illustrated in  FIG. 7 , the through portion  41  is positioned such that, when seen in the up-down direction, the edge portion  42  of the through portion  41  does not overlap with any of the connecting portions  25  positioned below the through portion  41 . That is, the through portion  41  is positioned such that the edge portion  42  of the through portion  41  does not overlap with any of the connecting portions  25  of the lower connecting units  50   a  when seen in the up-down direction. By disposing the edge portion  42  of the through portion  41  at a different position from the position of any of the connecting portions  25  of the lower connecting units  50   a  when seen in the direction of gravity Z, that is, the up-down direction, the likelihood of the liquid that drops through the through portion  41  adhering to any of the connecting portions  25  of the lower connecting units  50   a  is reduced. The through portion  41  according to the present embodiment is positioned such that, when seen in the up-down direction, the through portion  41  does not overlap with any of the connecting portions  25  positioned below the through portion  41 . 
     Each of the connecting units  50  may include a receiving portion  53  positioned below the connecting portion  25 . The receiving portion  53  receives the liquid leaking from the connecting portion  25 . In this case, when the receiving portion  53  receives the liquid leaking from the connecting portion  25 , this liquid flows along the receiving portion  53  and flows down toward the rear side in the depth direction Y. When the receiving portion  53  of the upper connecting unit  50   b  receives the liquid, this liquid flows down further to the rear side than the through portion  41  in the depth direction Y on the separator  40 . After that, the liquid having leaked flows along the edge portion  42  on the rear side in the depth direction Y and drops from the through portion  41 . 
     Next, operation and effects of the liquid ejecting apparatus  11  structured as above are be described. 
     1. When the liquid leaks from above the separator  40 , this liquid flows down on the separator  40 . The liquid leaking on the separator  40  drops through the through portion  41 . At this time, the liquid drops along the edge portion  42  of the through portion  41 . It is not preferable that, when the liquid drops, the liquid adhere to any of the connecting terminals (electrical members)  52  through which electricity flows. In this regard, according to the above-described embodiment, the edge portion  42  of the through portion  41  does not overlap with any of the connecting terminals (electrical members)  52  when seen in the up-down direction. This can reduce the likelihood of the liquid that drops from the through portion  41  adhering to any of the connecting terminals (electrical members)  52 . Accordingly, the likelihood of failures occurring due to the liquid having leaked can be reduced. 
     2. The through portion  41  is positioned such that the through portion  41  does not overlap with any of the connecting terminals (electrical members)  52  when seen in the up-down direction. That is, when seen in the up-down direction, the through portion  41  is disposed at a different position from the position of any of the connecting terminals (electrical members)  52  disposed below the through portion  41 . “This can reduce the likelihood of the liquid that drops from the through portion  41  adhering to any of the connecting terminals (electrical members)  52 . 
     3. When the liquid containers  17  mounted in the mounting unit  18  are connected to the connecting portions  25 , the liquid is supplied from the liquid containers  17  to the liquid ejecting head  15  through the connecting portions  25 . In the mounting unit  18  in which the plurality of liquid containers  17  can be mounted, the plurality of different liquid containers  17  containing different types of the liquid may be mounted. In this case, when the liquid that drops from the through portion  41  adheres to any of the connecting portions  25  positioned below the through portion  41 , different types of the liquid may be mixed with each other. In this regard, according to the above-described embodiment, the edge portion  42  of the through portion  41  does not overlap with any of the connecting portions  25  positioned below the through portion  41  when seen in the up-down direction. This can reduce the likelihood of the liquid that drops from the through portion  41  adhering to any of the connecting portions  25 . 
     4. The through portion  41  is positioned such that, when seen in the up-down direction, the through portion  41  does not overlap with any of the connecting portions  25  positioned below the through portion  41 . That is, when seen in the up-down direction, the through portion  41  is disposed at a different position from the positions of the connecting portions  25  disposed below the through portion  41 . This can further reduce the likelihood of the liquid that drops from the through portion  41  adhering to any of the connecting portions  25 . 
     5. The detection unit  60  is provided. The detection unit  60  is disposed below the mounting unit  18  and includes the detectors  61  that can detect adhering of the liquid. This allows the detectors  61  to detect the liquid having leaked. Accordingly, the user can be notified of leakage of the liquid. 
     6. The guide portion  62  includes the absorbing member  63  that can absorb the liquid. Thus, the liquid that drops from the through portion  41  is absorbed by the absorbing member  63 , thereby the liquid is guided to the detectors  61 . Accordingly, the liquid having leaked can be detected further quickly. 
     The above-described embodiment may be varied as in variations described below. The structures included in the above-described embodiment and structures included in the following variations may be arbitrarily combined, and the structures included in the following variations may be arbitrarily combined with each other. 
     As illustrated in  FIG. 8 , the separator  40  may have an inclined portion  81  downwardly inclined toward the through portion  41 . According to this variation, the inclined portion  81  is disposed behind the through portion  41  in the depth direction Y. This structure allows the liquid leaking from the connecting portion  25  to effectively flow toward the through portion  41 . The inclined portion  81  is continuous with the edge portion  42  of the through portion  41 . The inclined portion  81  may be disposed in front of the through portion  41 , or inclined portions  81  may be respectively disposed in front of and behind the through portion  41  in the depth direction Y. Furthermore, the inclined portion  81  may be adjacent to the through portion  41  in the width direction X. 
     According to this variation, the following effect can be obtained. 
     7. When the liquid leaks to the separator  40 , this liquid flows along the inclined portion  81 . Thus, the liquid having leaked can be guided to the through portion  41 . 
     As illustrated in  FIG. 9 , the separator  40  may have a groove  82  extending toward the through portion  41 . According to this variation, the groove  82  is disposed behind the through portion  41  in the depth direction Y. The groove  82  is continuous with the edge portion  42  of the through portion  41 . When the liquid having leaked to the separator  40  flows into the groove  82 , the liquid flows toward the through portion  41  due to a capillary force of the groove  82 . This allows the liquid leaking from the connecting portion  25  to effectively flow toward the through portion  41 . The groove  82  may be disposed in front of the through portion  41  in the depth direction Y. The groove  82  may be adjacent to the through portion  41  in the width direction X. A plurality of grooves  82  may be provided. 
     According to this variation, the following effect can be obtained. 
     8. When the liquid leaks to the separator  40 , this liquid flows into the groove  82 . Thus, the liquid can be guided to the through portion  41 . 
     As illustrated in  FIG. 10 , the mounting unit  18  may be structured such that the liquid directly drops to the bottom wall  12   a  of the housing  12  through the through portion  41 . 
     As illustrated in  FIG. 10 , it is preferable that the through portion  41  be positioned such that, when seen in the up-down direction, the edge portion  42  of the through portion  41  is superposed on part of the guide portion  62 . That is, it is preferable that the detection unit  60  include the guide portion  62  that is in contact with the detectors  61  and positioned such that part of the guide portion  62  is, when seen in the up-down direction, superposed on the edge portion  42  of the through portion  41 . With this structure, when the liquid drops from the through portion  41  to the bottom wall  12   a  of the housing  12 , the liquid is guided to the detectors  61  through the guide portion  62 . Accordingly, the liquid having leaked can be quickly detected. 
     According to this variation, the following effect can be obtained. 
       9 . The liquid having dropped from the through portion  41  is guided to the detectors  61  by the guide portion  62 . Thus, the liquid having leaked can be quickly detected. 
     The through portion  41  is not necessarily disposed in front of the upper connecting unit  50   b  in the depth direction Y. For example, as illustrated in  FIGS. 4, 6, and 7 , a through portion  45  may be disposed behind the upper connecting unit  50   b  in the depth direction Y. In this case, the through portion  41  may be provided or may be omitted. As is the case with the through portion  41 , the through portion  45  is positioned such that an edge portion  42  of the through portion  45  does not overlap with any of the connecting terminals  52  of the lower connecting units  50   a  when seen in the up-down direction. An inclined portion  81  or a groove  82  may be provided also for the through portion  45 . 
     The through portion  41  may be a cut formed by cutting part of the separator  40 . 
     The plurality of liquid containers  17  mounted in the mounting unit  18  may contain the liquid of the same type. 
     The number of the liquid containers  17  mountable in the mounting unit  18  may be five or larger or three or smaller. 
     The cassette  13  may be disposed below the mounting unit  18 . 
     The large-capacity liquid container  17  may be mounted on the lower stage in the mounting unit  18 . Alternatively, the capacity of the liquid containers  17  mounted in the mounting unit  18  may be the same. Two or more of the liquid containers  17  may be mounted on the upper stage in the mounting unit  18 . The number and the layout of the liquid containers  17  mounted in the mounting unit  18  can be changed as desired. 
     The detection unit  60  may include only a single detector  61 . 
     The guide portion  62  may have a groove having the detection portion  62   a  and the extended portions  62   b  therein. In this case, the guide portion  62  does not necessarily include the absorbing member  63 . When the guide portion  62  includes the absorbing member  63  and the groove, the liquid having leaked can be more quickly detected by fitting the absorbing member  63  into the groove. 
     The absorbing member  63  may have a mesh shape and intersections of the mesh may be used as the detection portion  62   a.    
     The absorbing member  63  may have a cross shape and an intersection of the cross shape may be used as the detection portion  62   a.    
     The shape of the extended portions  62   b  may be changed so that the level in height of the extended portions  62   b  of the absorbing member  63  is changed. This allows the extended portions  62   b  to be desirably disposed near positions where the liquid is likely to leak. 
     The detection portion  62   a  and the extended portions  62   b  may be, for example, integrally formed of a porous material or formed by connecting the extended portions  62   b  that are separate members and formed of a thread or a cord to the detection portion  62   a  formed of, for example, nonwoven fabric. 
     The liquid ejecting head  15  may be a line scan head elongated in the width direction X. 
     The liquid to be ejected by the liquid ejecting head  15  is not limited to the ink and may be a material in a liquid state or the like formed by, for example, dispersing a particle of a functional material in liquid or mixing a particle of a functional material with liquid. For example, the liquid ejecting head  15  may eject a material in a liquid state containing a material such as an electrode material or colorant (material of pixels) dispersed or dissolved therein used for the manufacture or the like of liquid crystal displays, electroluminescent (EL) displays, or field emission displays. 
     The medium  99  is not limited to a sheet of paper and may be a plastic film, a thin plate, or the like. Alternatively, the medium  99  may be fabric used for, for example, a textile printing device. Alternatively, the medium  99  may be clothing or the like having an arbitrary shape such as T-shirt or a three-dimensional object having an arbitrary shape such as tableware or a writing material. 
     Second Embodiment 
     As illustrated in  FIG. 11 , a liquid ejecting apparatus  211  includes a substantially rectangular parallelepiped-shaped exterior covering  212 . A cassette  216 , a cassette (medium containing unit)  215 , an output tray  218 , and an operating panel  219  are disposed in this order from the bottom to the top in the exterior covering  212  (see, for example,  FIGS. 11 and 13 ). The cassette  216  contains a mounting unit  214  on which trays (containers)  213  are removably mounted. The cassette  215  can contain media (not illustrated) such as sheets of printing paper. The media are output to the output tray  218 . The liquid ejecting apparatus  211  is operable through the operating panel  219 . The number of cassettes may be increased by disposing a different cassette  217  below the cassette  216  (see  FIG. 12 ). The exterior covering  212  may include a front lid (not illustrated) through which the mounting unit  214  can be exposed. In this case, it is preferable that the front lid be pivotable. 
     A liquid ejecting head  221  and a carriage  222  are provided in the exterior covering  212  (see  FIGS. 11 and 12 ). The liquid ejecting head  221  ejects liquid from nozzles. The carriage  222  reciprocates in a scan direction being coincident with the width direction of the liquid ejecting apparatus  211 . The liquid ejecting head  221  is moved together with the carriage  222  and ejects the liquid supplied from liquid supply members  220  toward the media. Thus, printing is performed on the media. 
     According to a second embodiment, the width direction is a direction intersecting (preferably, perpendicular to) a movement path for mounting the trays  213  on the mounting unit  214 , and the depth direction is a direction in which the movement path extends. Also, the width direction and the depth direction substantially extend along a horizontal plane. In the drawings, the direction of gravity is represented by the Z axis and the direction in which the movement path for mounting the trays  213  on the mounting unit  214  extends is represented by the Y axis on the assumption that the exterior covering  212  is placed on the horizontal plane. The width direction is represented by the X axis perpendicular to the Z axis and the Y axis. The width direction, the direction of gravity, and the front/rear direction (a direction in which mounting on the mounting unit  214  is performed) intersect or, preferably, are perpendicular to one another and respectively used as the directions when the lengths of the width, height, and the depth are described. 
     In the liquid ejecting apparatus  211  according to the present embodiment, the mounting unit  214  includes a first mounting portion  214 F and second mounting portions  214 S (see, for example,  FIGS. 13 and 16 ). The first mounting portion  214 F is formed in a bezel portion  2140 . A first liquid supply member  220 F is mounted in the first mounting portion  214 F. A plurality of, for example, three of the second mounting portions  214 S are disposed below the first mounting portion  214 F in the Z direction such that a plurality of, for example, three of second liquid supply members  220 S are mounted side-by-side therein in the horizontal direction (width direction). The first liquid supply member  220 F having a larger width than the width of the second liquid supply members  220 S can be mounted in the first mounting portion  214 F (see  FIG. 16 ). 
     The first liquid supply member  220 F is mounted in the liquid ejecting apparatus  211  by removably mounting the first liquid supply member  220 F on a first tray  213 F and mounting the first tray  213 F in the first mounting portion  214 F. Likewise, the second liquid supply members  220 S are mounted in the liquid ejecting apparatus  211  by removably mounting the second liquid supply members  220 S on second trays  213 S and mounting the second trays  213 S in the second mounting portions  214 S (see, for example,  FIG. 16 ). These liquid supply members  220 F,  220 S are formed by bag-shaped members (ink packs) filled with liquid for, for example, printing. As illustrated in, for example,  FIG. 16 , the liquid supply members  220 F,  220 S are mounted on the respective trays  213 F,  213 S in respective horizontal positions in which the width is larger than the height (see  FIG. 16 ). This can reduce the height of the mounting portions  214 F,  214 S. 
     The trays  213  are containers that are removably mountable in the mounting unit  214  with the liquid supply members  220  mounted thereon. The first tray  213 F is a single tray having a comparatively large size and mounted in the first mounting portion  214 F. The second trays  213 S include, for example, three trays mounted in the second mounting portions  214 S. As illustrated in, for example,  FIG. 16 , the width (length in the X direction) of the first tray  213 F is larger than the width of the second trays  213 S. These trays  213  can be repeatedly used and allow replacement of the liquid supply members  220 . 
     As described above, the mounting unit  214  includes the first mounting portion  214 F in which the first liquid supply member  220 F mounted on the first tray  213 F is mounted and the plurality of second mounting portions  214 S which are disposed below the first mounting portion  214 F and in which the second liquid supply members  220 S mounted on the second trays  213 S are mounted. With this mounting unit  214 , the likelihood of the liquid supply members  220  being damaged during operation such as mounting can be suppressed. More specifically, in the liquid ejecting apparatus  211  in which the liquid supply members  220  and their mounting portions  214  are arranged in two stages, that is, the upper and lower stages, when the upper tray is pulled forward and the user releases his or her hand from this upper tray while one of the lower trays are pulled forward in the Y-axis direction, the upper tray may become inclined. This may cause the upper tray to hit and give damage to the liquid supply member  220  on the lower tray being pulled. In contrast, in the case of the mounting unit  214  of the liquid ejecting apparatus  211  according to the present embodiment, even when the first tray  213 F is pulled forward in the Y-axis direction, the user releases the hand from the first tray  213 F, and the first tray  213 F is inclined while one or more second trays  213 S are pulled forward in the Y-axis direction, the bottom of the first tray  213 F is brought into contact with the upper edges of the side walls or the front surface of the second tray  213 S in the pulled state. Thus, the bottom of the first tray  213 F does not reach the second liquid supply member  220 S (see  FIG. 14 ). That is, the side walls and so forth of the second trays  213 S having a smaller width than the width of the first tray  213 F function as a stopper or a guard. This can prevent the liquid supply members mounted on the lower stage (that is, the second liquid supply members  220 S mounted on the second trays  213 S) from being damaged, or further, being flattened by being struck by the first tray  213 F. 
     In the mounting unit  214  of the liquid ejecting apparatus  211  according to the present embodiment, side regions A are provided in regions above the second mounting portions  214 S and outside the first mounting portion  214 F in the width direction (X direction) (see  FIG. 16 ). As illustrated in, for example,  FIG. 16 , the width of the first mounting portion  214 F is smaller than the entire width of a region including three of the second mounting portions  214 S, and spaces as the side regions A are formed outside the first mounting portion  214 F corresponding to the difference between the widths. In other words, the side regions A are spaces inside comparatively thick wall portions near respective sides of the first mounting portion  214 F. According to the present embodiment, a total of two side regions A are provided at respective side positions between which the first mounting portion  214 F is interposed (see  FIG. 16 ). In one of the side regions A on one side, one side portion of the first mounting portion  214 F is positioned further to the inside by a width Aw 1  than a side portion of one of the second mounting portions  214 S below the one side portion of the first mounting portion  214 F, and in the other side region A on the other side, the other side portion of the first mounting portion  214 F is positioned further to the inside by a width Aw 2  than a side portion of one of the second mounting portions  214 S below the other side portion of the first mounting portion  214 F (see  FIG. 16 ). Both of the spaces as the side regions A on both sides have a depth the length of which is, in the depth direction (Y direction), about the same as the length of the first tray  213 F mounted in the first mounting portion  214 F. 
     The space can be effectively used by laying out other elements of the liquid ejecting apparatus  211  in the side regions A. For example, a plurality of supply channels  230  for the liquid are provided according to the present embodiment, and at least part of each of some of the supply channels  230  passes through one of the side regions A (see  FIGS. 14 and 15 ). Here, “at least part of each of the supply channels  230 ” refers to a portion of the supply channel  230  that is secured and not moving. For example, as will be described, a redirecting portion  237  of the supply channel  230  disposed in and secured at the side region A is “at least part of each of the supply channels  230 ”. 
     The liquid is supplied from the first mounting portion  214 F and the second mounting portions  214 S toward the liquid ejecting head  221  through the supply channels  230 . Each of the supply channels  230  is provided for a corresponding one of the types (colors according to the present embodiment) of the liquid.  FIG. 13  and after illustrate connecting portions  232  being upstream ends to which the liquid supply members  220  are connected, flexible supply tubes  233 , and a coupling unit  238  provided at downstream ends of the supply tubes  233 . In addition to these, although they are not illustrated, downstream supply channels that allow communication from the coupling unit  238  to the liquid ejecting head  221  are provided. The supply channels  230  according to the present embodiment include a first supply tube  233 F and second supply tubes  233 S. The liquid in the first liquid supply member  220 F mounted in the first mounting portion  214 F is supplied to the liquid ejecting head  221  through a single first supply tube  233 F. The liquid in the second liquid supply members  220 S mounted in the second mounting portions  214 S is supplied to the liquid ejecting head  221  through three of the second supply tubes  233 S (see  FIGS. 14 and 15 ). The coupling unit  238  can be removably connected to the downstream supply channels and is disposed on the front side of the liquid ejecting apparatus  211  in the Y direction (see, for example,  FIG. 15 ). 
     Furthermore, the redirecting portions  237  are formed in the supply channels  230 . The redirecting portions  237  redirect from the horizontal direction to the vertical direction the direction in which the liquid flows in one of the side regions A (see  FIGS. 13 to 15 ). According to the present embodiment, the redirecting portions  237  are disposed in only one of two side regions A. This allows the other side region A to be allocated to another use. The redirecting portions  237  are disposed, for example, near the center of the side region A in the depth direction (Y direction). According to the present embodiment, three of the second supply tubes  233 S are horizontally routed between the first mounting portion  214 F and the second mounting portions  214 S, and the redirecting portions  237  of the second supply tubes  233 S are gathered. Then, the second supply tubes  233 S are redirected from the horizontal direction to the vertical direction at the redirecting portions  237  arranged in the width direction (X direction). In other words, the side region A is formed as a space that allows the second supply tubes  233 S, which correspond in number to the second liquid supply members  220 S mounted in the second mounting portions  214 S, to be arranged in the width direction. A guide for redirecting the second supply tubes  233 S from the horizontal direction to the vertical direction may be provided in the side region A. 
     As has been described, with the redirecting portions  237  disposed in the side region A, tubes can be routed without an increase in the footprint of the apparatus while increasing the capacity of the liquid. In a form in which two redirecting portions  237  are formed in each of the second supply tubes  233 S, the redirecting portions  237  may be disposed in two side regions A. 
     Pump chambers (not illustrated) are provided between the connecting portions  232  and the supply tubes  233 . Downstream ends of the connecting portions  232  and upstream ends of the supply tubes  233  are communicated with the pump chambers. The pump chambers are separated from pressure varying chambers (not illustrated) with flexible films (not illustrated) interposed therebetween. 
     The liquid contained in the liquid supply members  220  is fed to the supply channels  230  by a supply mechanism  231 . The supply mechanism  231  includes, for example, a pressure varying mechanism  234 , a drive source (for example, a motor)  235  for the pressure varying mechanism  234 , and a pressure varying channel  236  that connects the pressure varying mechanism  234  to the pressure varying chambers. When the drive source  235  is driven, the pressure varying mechanism  234  depressurizes the pressure varying chambers through the pressure varying channel  236 . This causes the flexible films to be bent toward the pressure varying chambers, thereby reducing the pressure of the pump chambers. Due to the reduction in the pressure of the pump chambers, the liquid contained in the liquid supply members  220  is sucked into the pump chambers through the connecting portions  232 . Then, when the pressure varying mechanism  234  cancels the depressurization of the pressure varying chambers through the pressure varying channel  236 , the flexible films is bent toward the pump chambers, thereby increasing the pressure of the pump chambers. As a result, due to the increase in the pressure of the pump chambers, the liquid in the pump chambers flows out into the supply tubes  233  while being pressurized. The supply mechanism  231  alternately performs suction and discharge repeatedly, thereby supplying the liquid from the liquid supply members  220  to the liquid ejecting head  221 . 
     As has been described, with the liquid ejecting apparatus  211  according to the present embodiment, the first liquid supply member  220 F mounted in the first mounting portion  214 F and the second liquid supply members  220 S mounted in the second mounting portions  214 S can be arranged in the up-down direction. Thus, the capacity of the liquid supply members  220  can be increased without the increase in the footprint of the apparatus. Accordingly, the capacity of a color an increase of which is desired (for example, black) can be comparatively easily increased. 
     The embodiments having been described are intended to facilitate understanding of the invention and not to interpret the invention in a limited manner. The elements included in the embodiments and arrangement, materials, conditions, shapes, sizes, and so forth of the elements are not limited to those of the exemplified elements and can be appropriately changed. Furthermore, structures described in the different embodiments can be partially replaced or combined with one another. 
     In the mounting unit  214  of the liquid ejecting apparatus  211 , the first mounting portion  214 F may be disposed below the second mounting portions  214 S (see  FIG. 17 ). In this case, the width of the first tray  213 F (or the first liquid supply member  220 F) mounted in the first mounting portion  214 F may be larger than or equal to the entire width of a region including a plurality of, for example, three of the second trays  213 S (or the second liquid supply members  220 S) mounted in the second mounting portions  214 S. In  FIG. 17 , side regions formed outside the second mounting portions  214 S in the width direction (X direction) are denoted by sign B. 
     In the liquid ejecting apparatus  211 , the cassette (medium containing unit)  215  may be disposed such that the cassette  215  and the first mounting portion  214 F are arranged in the vertical direction and the cassette  215  is positioned above the first mounting portion  214 F. Alternatively, the cassette  215  may be disposed such that the cassette  215  and the second mounting portions  214 S are arranged in the vertical direction and the cassette  215  is positioned below the second mounting portions  214 S. Alternatively, cassettes  215  are provided at both the above-described positions (see  FIG. 12 ). 
     When a plurality of medium containing units that respectively contain the media of different sizes are provided, it is preferable that the medium containing unit that contains the media of a smallest size be disposed above the mounting unit  214 . In such a case, spaces can be obtained on both sides of the medium containing unit. This facilitates the layout of other elements. 
     Technical ideas and operational effects understood from the above-described embodiments are described below. 
     Idea 1 
     A liquid ejecting apparatus includes a liquid ejecting head and a mounting unit. The liquid ejecting head is able to eject liquid. A plurality of liquid containers containing the liquid to be supplied to the liquid ejecting head are mounted so as to overlap in an up-down direction. The mounting unit includes a separator and an electrical member. The separator separates, in the up-down direction, a space where the plurality of liquid containers are mounted. The electrical member allows electricity to flow therethrough. The separator has a through portion that penetrates through the separator in the up-down direction. The through portion is positioned such that, when seen in the up-down direction, an edge portion of the through portion does not overlap with the electrical member positioned below the through portion. 
     When the liquid leaks from above the separator, this liquid flows down on the separator. The liquid leaking on the separator drops through the through portion. At this time, the liquid drops along the edge portion of the through portion. It is not preferable that, when the liquid drops, the liquid adhere to the electrical member through which electricity flows. In this regard, according to the above-described embodiment, the edge portion of the through portion does not overlap with the electrical member positioned below the through portion when seen in the up-down direction. This can reduce the likelihood of the liquid that drops from the through portion adhering to the electrical member. Accordingly, the likelihood of failures occurring due to the liquid having leaked can be reduced. 
     Idea 2 
     In the liquid ejecting apparatus according to Idea 1, the through portion is positioned such that, when seen in the up-down direction, the through portion does not overlap with the electrical member. 
     With this structure, when seen in the up-down direction, the through portion is disposed at a different position from the position of the electrical member disposed below the through portion. This can further reduce the likelihood of the liquid that drops from the through portion adhering to any of the electrical member. 
     Idea 3 
     In the liquid ejecting apparatus according to Idea 1 or 2, the mounting unit includes a plurality of connecting portions to which the plurality of liquid containers mounted in the mounting unit are respectively connected. In this case, the plurality of connecting portions allow the liquid to be supplied from the plurality of liquid containers connected thereto toward the liquid ejecting head.
