CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a Continuation of U.S. patent application Ser. No. 14/225,802 filed on Mar. 26, 2014, which claims priority to Japanese Patent Application No. 2013-072176, filed on Mar. 29, 2013, which applications are hereby incorporated by reference in their entirety. 
    
    
     BACKGROUND 
     1. Technical Field 
     The present invention relates to a recording apparatus which is represented by a fax machine, a printer, or the like. 
     2. Related Art 
     In recording apparatuses which are represented by a fax machine, a printer, or the like, there is an apparatus which can execute recording on both surfaces of a printing sheet as an example of a medium. Such a recording apparatus has a reversing path on which a recording sheet is reversed, and the recording sheet on which recording is performed is reversed on the reversing path, and is transported to a region facing a recording head again by having the rear surface as the front surface. 
     Further, there is an apparatus which includes a manual feeding path for feeding and sending a recording sheet manually, in addition to the above described reversing path. A configuration which includes such a reversing path and a manual feeding path is disclosed in JP-A-2006-160507, and JP-A-2005-219860. 
     An image forming apparatus which is described in JP-A-2006-160507 includes a manual feeding tray on the rear surface side of the apparatus, and is configured so as to feed a sheet manually from the manual feeding tray which extends from the rear surface side of the apparatus. For this reason, there is a problem in that a space is necessary on the rear surface side of the apparatus, it is not easy to handle, and a dimension in the depth direction of the entire apparatus becomes large. 
     An image forming apparatus which is described in JP-A-2005-219860 includes an opening portion for manual feeding on the rear surface side of a main body of the apparatus. Accordingly, similarly to the image forming apparatus which is described in JP-A-2006-160507, a space for manual feeding is necessary on the rear surface side of the apparatus, and it is not easy to handle. In addition, similarly to the image forming apparatus which is described in JP-A-2006-160507, since a recording unit, transport paths for printing on both faces, and a paper support are arranged in the vertical direction of the apparatus in an overlapping manner, as a matter of fact, dimensions in the vertical direction of the apparatus become large. 
     SUMMARY 
     An advantage of some aspects of the invention is to provide a recording apparatus in which paths for printing on both faces and a manual feeding path are included, manual feeding is easily performed, and an installation space is made small. 
     According to an aspect of the invention, there is provided a recording apparatus which includes a recording head which performs recording on a medium; a first roller which reverses a medium which is transported from the recording head side; a second roller of which a peripheral surface faces both a medium transport path portion before reversing due to the first roller and a medium transport path portion after reversing, and applies a transport force to the medium; and a medium reception unit which receives a medium which is discharged, in which the medium reception unit also functions as a first medium support unit which supports a medium which is inserted from a medium discharging direction side of the medium. 
     According to the aspect, since the medium reception unit which receives a discharged medium functions as the first medium support unit which supports the medium which is inserted from the discharging direction side of the medium, it is possible to reduce a cost of the apparatus. In addition, since feeding of the medium through the medium reception unit (first medium support unit) is performed from the discharging direction side of the medium, an operability is good, and a large installation space is not necessary on the side opposite to the discharging direction side of the medium (usually, rear surface side of apparatus), and accordingly, it is possible to reduce the installation space of the apparatus. 
     In addition, since a reversing path for reversing the medium includes the first roller which reverses the medium, and the second roller of which the peripheral surface faces both the medium transport path before reversing and the medium transport path after reversing due to the first roller, and which applies the transport force to the medium, it is possible to secure the length of the reversing path for reversing the medium using the second roller while preventing a diameter of the first roller from increasing. 
     In addition, since the second roller faces both the medium transport path before reversing due to the first roller and the medium transport path after reversing, and applies the transport force to the medium, it is possible to reduce the number of rollers which is arranged when one roller (the second roller) can contribute to both the medium transport path before reversing and the medium transport path after reversing, and to suppress a cost increase. 
     In the recording apparatus, a transport path of a medium which is inserted through the medium reception unit may join the medium transport path before reversing due to the first roller, or the medium transport path after reversing. 
     According to the aspect, since the transport path of the medium which is inserted through the medium reception unit joins the medium transport path before reversing, or the medium transport path after reversing due to the first roller, it is possible to suppress the cost increase in the apparatus by sharing the transport path. 
     In the recording apparatus, the transport path of the medium which is inserted through the medium reception unit may be joined at a position of the second roller in the medium transport path before reversing due to the first roller. 
     According to the aspect, since the transport path of the medium which is inserted through the medium reception unit is joined at the position of the second roller in the medium transport path before reversing due to the first roller, it is possible to apply the transport force to the medium at many more positions, and to transport the medium further reliably. 
     The recording apparatus may further include a second medium support unit which supports the medium which is inserted into the apparatus, in which a transport path of the medium which is inserted through the second medium support unit joins the transport path on which the medium which is inserted through the medium reception unit at a position of the first roller or the second roller is transported. 
     According to the aspect, the recording apparatus further includes a second medium support unit which supports a medium which is inserted into the apparatus, and since a transport path of the medium which is inserted through the second medium support unit joins the transport path on which the medium which is inserted through the medium reception unit is transported at a position of the first roller or the second roller, it is possible to suppress the cost increase of the apparatus by sharing a transport path in a configuration which includes a plurality of medium transport paths. 
     The recording apparatus may further include a medium accommodating unit which is provided at a position lower than the recording head in a vertical direction of the apparatus, can handle a medium from the discharging direction side of the medium, and accommodates the medium, in which the medium which is sent out from the medium accommodating unit passes through at least a part of a reversing transport path which is formed by the first roller, and reaches a position facing the recording head. 
     According to the aspect, it is possible to make the operability good since the medium accommodating unit can handle the medium from the discharging direction side of the medium, and feeding of the medium through the medium reception unit is also performed from the discharging direction side of the medium, and it is possible to make the installation space of the apparatus small, since it is not necessary to provide a large installation space on the side opposite to the discharging direction side of the medium (usually, rear surface side of apparatus). 
     In the recording apparatus, at least a part of a region occupied by the reversing transport path may be located at an upper part of the medium accommodating unit. 
     According to the aspect, since at least a part of the region occupied by the reversing transport path is located at the upper part of the medium accommodating unit, it is possible to further reduce a dimension of the apparatus in a horizontal direction, and to provide a further minimized apparatus. 
     In the recording apparatus, the transport path on which the medium which is inserted through the medium reception unit is transported may join the transport path on which the medium which is sent out from the medium accommodating unit is transported, and on the transport path on which the medium which is inserted through the medium reception unit is transported, a pair of transport rollers which nips and transports a medium is provided on an upstream side in the medium transport direction of the position at which the transport path on which the medium which is sent out from the medium accommodating unit is transported is joined. 
     According to the aspect, since the pair of transport rollers which nips and transports the medium is provided on the upstream side in the medium transport direction of the position at which the transport path on which the medium which is sent out from the medium accommodating unit is transported is joined in the transport path on which the medium which is inserted through the medium reception unit is transported, it is not necessary to insert the medium to a deep portion of the apparatus, and it is possible to easily insert the medium when feeding the medium through the medium support unit. 
     In the recording apparatus, the medium accommodating unit may be detached from a main body of the recording apparatus, a path forming member which forms the transport path of the medium which is inserted through the medium reception unit may be provided along with the medium reception unit at an upper part of a mounting region of the medium accommodating unit in the main body of the apparatus, and the path forming member may be provided so as to switch between a first state in which the transport path of the medium which is inserted through the medium reception unit is formed along with the medium support unit and a second state in which the transport path of the medium which is inserted through the medium reception unit is exposed to the discharging direction side of the medium by descending of the path forming member to the mounting region from the upper part of the mounting region of the medium accommodating unit. 
     According to the aspect, since the path forming member which forms the transport path of the medium which is inserted through the medium reception unit along with the medium reception unit can expose the transport path to the discharging direction side of the medium by coming down to the mounting region from the upper part of the mounting region of the medium accommodating unit, it is possible to remove a jammed medium from the discharging direction side of the medium, that is, it is possible to easily remove the jammed medium when a medium is jammed on the transport path of the medium which is inserted through the medium reception unit. 
     In the recording apparatus, one roller of the pair of transport rollers may be provided in the path forming member, and the one roller of the pair of transport rollers may be separated from the other roller when the path forming member is switched from the first state to the second state. 
     According to the aspect, since the one roller of the pair of transport rollers is provided in the path forming member, and the one roller of the pair of transport rollers is separated from the other roller when the path forming member switches from the first state to the second state, it is possible to release a nipped state of a medium due to the pair of transport rollers, and to further easily remove a jammed medium. 
     In the recording apparatus, the path forming member may include a unit to be regulated which can be engaged with a regulation unit which is formed on a base configuring the mounting region of the medium accommodating unit, and when the unit to be regulated engages with the regulation unit, a displacement of the path forming member from the medium discharging direction side to the opposite side thereof may be regulated when the path forming member is in the second state. 
     When the medium accommodating unit is inserted into the mounting region in a state in which the path forming member comes down to the mounting region, there is a concern that the path forming member, or a mounting structure unit of the path forming member may be damaged. However, according to the aspect, since the unit to be regulated is provided in the path forming member, the unit to be regulated engages with the regulation unit which is formed on the base configuring the mounting region of the medium accommodating unit in the second state, and since the displacement of the path forming member from the medium discharging direction side to the opposite side thereof is regulated, it is possible to avoid the above described damage.

In addition, in  FIG. 2 , the rear surface cover  22  is in a closed state with respect to the apparatus main body  12 . 
     Subsequently, a transport path of a medium in the printer  10  will be described. The printer  10  includes the medium accommodating unit  20 , a feeding unit  24 , a transport unit  26 , a recording unit  28 , and a discharging unit  30  in the apparatus main body  12 . The medium accommodating unit  20  is configured so as to be mounted on, and detached from the front side of the apparatus (−Y direction side in  FIG. 3 ) with respect to the apparatus main body  12  (refer to  FIG. 6 ). 
     In addition, the medium accommodating unit  20  is provided at the lower part of a recording head  58  of a recording unit  28  which will be described later in the Z axis direction, and is configured so as to handle a medium from the front side of the apparatus (−Y side in  FIG. 3 ). In addition, the medium is plain paper, cardboard, glossy paper, or the like, which can be used in the printer  10 . 
     The feeding unit  24  includes a pickup roller  32  and a feeding roller  34 . The pickup roller  32  sends out a medium at the top to the feeding roller  34  from the medium accommodating unit  20  by rotating by being in contact with the medium at the top which is accommodated in the medium accommodating unit  20  when the medium accommodating unit  20  is mounted on the apparatus main body  12 . 
     When the medium accommodating unit  20  is mounted on the apparatus main body  12 , the feeding roller  34  transports a medium to the transport unit  26  which is located on the downstream side of the transport path by nipping the medium with a feeding driven roller  36  which is located at a position on the +Y direction side in the medium accommodating unit  20 , that is, arranged on the tip end side of the medium accommodating unit  20 . 
     In addition, the inner surface  22   a  of the rear surface cover  22 , that is, the surface on the −Y direction side in  FIG. 1  configures a part of the transport path of the medium to the transport unit  26  from the feeding unit  24  when the rear surface cover  22  is in a closed state with respect to the apparatus main body  12 . 
     The transport unit  26  includes a first roller  38 , a second roller  40 , a first driven roller  42 , a second driven roller  44 , a third driven roller  46 , a fourth driven roller  48 , and a fifth driven roller  50  as “driven rollers”, and a pair of first transport rollers  52 . In addition, the first and second rollers  38  and  40  configure a reversing transport path  54 . 
     In addition, the first and second rollers  38  and  40  are rotatably driven counterclockwise, respectively, by a driving mechanism (not shown). In addition, in the example, the first driven roller  42 , the second driven roller  44 , the third driven roller  46 , the fourth driven roller  48 , and the fifth driven roller  50  are provided on the apparatus main body  12  side. 
     The reversing transport path  54  is configured so as to be detached from the apparatus main body  12 . Specifically, the reversing transport path can be detached from the apparatus main body  12  by being displaced to the +Y direction side in a state in which the rear surface cover  22  is open to the apparatus main body  12  (not shown). In addition, when the reversing transport path  54  is inserted into the apparatus main body  12  from the +Y direction side, and the rear surface cover  22  is closed with respect to the apparatus main body  12  in a state in which the reversing transport path  54  is detached from the apparatus main body  12 , the reversing transport path  54  is attached to the apparatus main body  12 . 
     In the transport unit  26 , the medium is transported to the pair of first transport rollers  52  through the fifth driven roller  50  and the third driven roller  46  which come into contact with the first roller  38 , and the second driven roller  44  and the first driven roller  42  which come into contact with the second roller  40  along the transport path. The recording unit  28  is provided on the downstream side in the transport path of the pair of first transport rollers  52  of the transport unit  26 . 
     The recording unit  28  includes a carriage  56  which is movable in the scanning direction (X axis direction in  FIG. 3 ), the recording head  58  which is provided under the carriage  56 , and ejects ink to the medium, and a platen  60  which faces the recording head  58 , and is provided so as to support the medium. 
     In addition, the transport path of the medium from the medium accommodating unit  20  to a position facing the recording head  58  through the inner surface  22   a  of the rear surface cover  22 , the fifth driven roller  50  and the third driven roller  46  which come into contact with the first roller  38 , the second driven roller  44  and the first driven roller  42  which come into contact with the second roller  40 , and the pair of first transport rollers  52  is set as a first medium transport path  61  of the medium. That is, the first medium transport path  61  is configured as a transport path which extends from the medium accommodating unit  20  to a position facing the recording head  58  through at least a part of the reversing transport path  54 . 
     In addition, a discharging unit  30  is provided on the downstream side in the transport path of the recording unit  28 . A pair of discharging rollers  62 , and a first medium support tray  64  in which the medium discharged from the discharging rollers  62  is placed, and which also functions as a discharging stacker are provided by protruding from the opening portion  18  to the front side of the apparatus (−Y direction) in the discharging unit  30 . The medium which is sent to the recording unit  28  from the transport unit  26  along the transport path is subject to recording on the front surface thereof. After the recording, the medium is nipped by the discharging roller  62 , and is discharged to the first medium support tray  64  which is provided on the front side of the apparatus, through the opening portion  18 . 
     In addition, when recording is performed on both surfaces of the medium in the printer  10 , recording is performed on the first surface of the medium using the recording unit  28 , and then the medium is returned to the reversing transport path  54  by having the side which becomes a rear end of the medium when being subject to the recording on the front surface as a tip end, due to backward feeding of the pair of first transport rollers  52  and the discharging roller  62 . At this time, the medium is sent toward the fourth driven roller  48  which is located on the −Z direction side of the second roller  40  in the Z axis direction. 
     In addition, the medium is nipped by the second roller  40  and the fourth driven roller  48 , is sent to a position between the first roller  38  and a support plate  65  which is located under the first roller, and is transported to the recording unit  28  again through the fifth driven roller  50  and the third driven roller  46  which come into contact with the first roller  38 , the second driven roller  44  and the first driven roller  42  which come into contact with the second roller  40 , and the pair of first transport rollers  52 . In addition, recording is performed on the rear surface of the medium in the recording unit  28 . Thereafter, the medium is nipped by the discharging roller  62 , and is discharged to a medium reception unit  75  which also functions as the first medium support unit which is provided on the front side of the apparatus, and will be described later, through the opening portion  18 . 
     In addition, a second medium support tray  66  as a “second medium support unit” is provided in the apparatus main body  12  at a position which is overlapping on the +Z direction side in the Z axis direction and the Y axis direction of the reversing transport path  54 . The medium which is supported by the second medium support tray  66  is sent to the downstream side of the transport path of a feeding roller by a feeding roller  68  which is provided so as to face the second medium support tray on the −Z direction side of the second medium support tray  66 . A transport path on the second medium support tray side  70  is provided on the downstream side of the transport path of the feeding roller  68 . 
     The transport path on the second medium support tray side  70  joins the transport path of the medium from the medium accommodating unit  20 , that is, the first medium transport path  61  between the first driven roller  42  and the second driven roller  44  which come into contact with the second roller  40  in the reversing transport path  54 . For this reason, the medium which is supported by the second medium support tray  66  joins the first medium transport path  61  through the transport path on the second medium support tray side  70  using the feeding roller  68 , is sent to the recording unit  28 , and is subject to recording. 
     In addition, since the transport path on the second medium support tray side  70  joins the first medium transport path  61  at a position of the second roller  40  in the reversing transport path  54 , it is possible to suppress the cost increase of the apparatus by sharing the transport path in a configuration including a plurality of medium transport paths. 
     Subsequently, the reversing transport path  54  will be described. The reversing transport path  54  is located on the side opposite to the medium discharging direction side with respect to the recording head  58  of the recording unit  28 , that is, on the +Y direction side in  FIG. 1 , and is provided at a position at which a region occupied in the vertical direction of the apparatus, that is, in the Z axis direction overlaps with a region occupied by the recording head  58  in the Z axis direction. In addition, at least a part of a region occupied by the reversing transport path  54  is located at the upper part of the medium accommodating unit  20 . 
     Since the reversing transport path  54  which reverses a medium is located on the +Y direction side in  FIG. 1  with respect to the recording head  58 , and is provided at a position at which the region occupied in the Z axis direction overlaps with the region occupied by the recording head  58  in the Z axis direction, it is possible to reduce a dimension in the vertical direction of the apparatus main body  12 , that is, in the Z axis direction. In addition, since at least a part of the region occupied by the reversing transport path  54  is located at the upper part of the medium accommodating unit  20 , it is possible to further reduce the dimension of the apparatus main body  12  in the Y axis direction in  FIG. 1 , and to provide a further minimized apparatus. 
     In addition, the reversing transport path  54  which is detachable from the apparatus main body  12  includes a reversing transport path unit  72  to which the first roller  38  and the second roller  40  are rotatably attached. The first roller  38  and the second roller  40  are arranged with a gap therebetween in the Y axis direction in the reversing transport path unit  72 , and are arranged at an overlapping position in the Z axis direction. In addition, the first roller  38  is located on the upstream side of the second roller  40  in the first medium transport path  61 . 
     In addition, the first roller  38  is attached to the reversing transport path unit  72  so that the peripheral surface thereof protrudes from the upper face and the lower face in the Z axis direction, and a rear end of the reversing transport path unit  72  in the Y axis direction. In addition, the second roller  40  is attached to the reversing transport path unit  72  so that the peripheral surface thereof protrudes from the top face and the lower face of the reversing transport path unit  72  in the Z axis direction. 
     For this reason, the first roller  38  can reverse the medium which is sent out from the recording head  58  of the recording unit  28  using the outer peripheral surface thereof. In addition, the second roller  40  can apply a transport force to the medium when the outer peripheral surface thereof faces a transport path portion before reversing due to the first roller  38 , that is, the transport path portion on the lower face side of the reversing transport path unit  72 , and a transport path portion after reversing, that is, a transport path portion on the top face side of the reversing transport path unit  72 . 
     In this manner, the reversing transport path  54  configures at least a part of the first medium transport path  61 , and a reversing path  74  which reverses the medium which is returned to the reversing transport path  54  from the recording head  58  due to the first roller  38 , and returns the medium to the recording head  58 . 
     In addition, since the medium reception unit (first medium support unit)  75  which receives a discharged medium also functions as the first medium support unit  75  which supports the medium which is inserted from the medium discharging direction side, it is possible to reduce a cost of the apparatus. In addition, since feeding of the medium through the medium reception unit (first medium support unit) is performed from the medium discharging direction side (−Y direction side), the operability is good, and it is not necessary to provide a large space on the +Y direction side which is the side opposite to the medium discharging direction side (usually, rear surface side of apparatus), and accordingly, it is possible to make the installation space of the apparatus small. 
     In addition, since the reversing transport path  54  includes the first roller  38  which reverses the medium, and the second roller  40  which can apply the transport force to the medium when the outer peripheral surface faces both the transport path portion before reversing due to the first roller  38 , that is, the reversing transport path  74  and the transport path portion after reversing, that is, the first medium transport path  61 , it is possible to secure the length of the reversing path for reversing the medium using the second roller  40  while preventing a diameter of the first roller  38  from increasing, and to correspond to a medium of a large size while preventing a size of the apparatus from increasing. 
     In addition, since the second roller  40  applies the transport force to the medium by facing both the transport path portion before reversing due to the first roller  38 , that is, the reversing transport path  74  and the transport path portion after reversing, that is, the first medium transport path  61 , it is possible to reduce the number of rollers which are arranged thereon, and to reduce the cost increase when the second roller  40  contributes to both the transport path portion before reversing, that is, the reversing transport path  74  and the transport path portion after reversing, that is, the first medium transport path  61 . 
     EXAMPLE 
     Subsequently, the first medium support unit  75  which also functions as the medium reception unit  75  and a second medium transport path  78  will be described with reference to  FIGS. 1 to 6 . The first medium support unit  75  includes the first medium support tray  64  and a paper guiding unit  76 . In the apparatus main body  12 , the paper guiding unit  76  is provided so as to be located between the recording head  58  of the recording unit  28  and the medium accommodating unit  20  as illustrated in  FIG. 1 . The paper guiding unit  76  is configured so as to be inserted from the first surface side to the second surface side in the opening portion  18 , that is, from the −Y direction side to the +Y direction side in the Y axis direction in  FIG. 1 , and guide the medium which is supported by the first medium support tray  64  to the downstream side of the transport path. 
     Here, since the medium accommodating unit  20  can handle the medium from the −Y direction side in  FIG. 1  which is the medium discharging direction side, and feeding of the medium through the paper guiding unit  76  is also performed from the −Y direction side which is the medium discharging direction side, the operability is very good, and it is not necessary to provide a large installation space on the +Y direction side which is the side opposite to the medium discharging direction side (usually, rear surface side of apparatus) in  FIG. 1 , and accordingly, it is possible to make the installation space of the apparatus small. 
     In addition, the apparatus main body  12  includes a path forming member  80  on the +Y direction side of the paper guiding unit  76  in the Y axis direction. The path forming member  80  is provided at the upper part of the mounting region of the medium accommodating unit  20  along with the paper guiding unit  76  in the apparatus main body  12 . The first medium support tray  64 , the paper guiding unit  76 , and the path forming member  80  form the second medium transport path  78  in the first state (state illustrated in  FIG. 1 ) which will be described later. 
     In addition, the second medium transport path  78  joins the second roller  40  in the transport path portion before reversing due to the first roller  38  in the transport unit  26 , that is, in the reversing path  74 , and joins the first medium transport path  61  on the upstream of a contact position with the fourth driven roller  48  which comes into contact with the second roller  40 . 
     That is, since the second medium transport path  78  of the medium which is inserted through the first medium support unit (medium reception unit)  75  joins the medium transport path before reversing, or the medium transport path after reversing due to the first roller  38 , it is possible to suppress the cost increase of the apparatus by sharing the transport path. 
     Since the second medium transport path  78  of the medium which passes through the first medium support unit  75  is joined at the position of the second roller  40  in the transport path portion before reversing due to the first roller  38 , that is, the reversing path  74 , it is possible to apply the transport force to the medium at many more positions, and to further reliably transport the medium. 
     In addition, a pair of second transport rollers  82  as “pair of transport rollers” which transports the medium to the upstream side in the medium transport direction of a position at which the second medium transport path  78  joins the first medium transport path  61  is provided in the second medium transport path  78 . The pair of second transport rollers  82  includes a second transport driven roller  84  (refer to  FIGS. 2 and 3 ) as “one roller” which is provided in the path forming member  80 , and a second transport driving roller  86  as “the other roller” which is provided on the apparatus main body  12  side. In addition, the second transport driving roller  86  is rotatably driven counterclockwise due to a driving source which is not shown. 
     In addition, a plurality of the second transport driven rollers  84  are provided with a gap therebetween in the X axis direction in  FIG. 2 . In addition, the second transport driving roller  86  (not shown) is also provided at a position corresponding to the second transport driven rollers  84  in the X axis direction on the apparatus main body  12  side. For this reason, since the medium is nipped by the plurality of pair of second transport rollers  82  in the X axis direction in  FIG. 2  when transporting the medium in the second medium transport path  78 , it is possible to prevent meandering of the medium when being transported. 
     Accordingly, the medium which is supported by the first medium support unit  75  in the second medium transport path  78  is transported along the second medium transport path  78  by the pair of second transport rollers  82 , and is sent out to the first medium transport path  61  which joins the second medium transport path  78 . 
     In the second medium transport path  78  to which the medium which is inserted through the first medium support unit (medium reception unit)  75  is transported, the pair of second transport rollers  82  which nips and transports the medium is provided on the upstream side in the medium transport direction of the position at which the second medium transport path  78  joins the first medium transport path  61  on which the medium which is sent out from the medium accommodating unit  20  is transported. The upstream side in the medium transport direction of the position at which the second medium transport path joins the first medium transport path  61  is the −Y direction side in  FIG. 1  which is the medium discharging direction side. Due to this, since the pair of second transport rollers  82  nips the medium at a position which is closer to the first medium support unit  75  on the −Y direction side, when the medium is supplied trough the first medium support unit  75 , it is not necessary to insert the medium into a deep position of the apparatus main body  12 , and it is possible to easily insert the medium. 
     When referring to  FIGS. 2 and 3 , the paper guiding unit  76  extends in the X axis direction, and includes a pair of medium edge guides  88 . The pair of medium edge guides  88  is configured so as to move in a direction in which the guides become closer to each other, or are separated from each other in the X axis direction in  FIG. 2 . 
     The pair of medium edge guides  88  aligns the medium by being in contact with both side portions of the medium when the medium is set in the paper guiding unit  76 , and prevents meandering of the medium when the medium is transported to the downstream side of the second medium transport path  78  by being nipped by the pair of second transport rollers  82 . 
     In addition, the path forming member  80  will be described in detail with reference to  FIGS. 4 to 6 . The path forming member  80  is configured so as to rotate with respect to the apparatus main body  12 . That is, the path forming member  80  is configured so as to switch between the first state in which the first medium support tray  64 , the paper guiding unit  76 , and the second medium transport path  78  are formed (refer to  FIG. 1 ) and the second state in which the second medium transport path  78  is exposed to the medium discharging direction side, that is, the −Y direction side in  FIG. 6  (refer to  FIG. 6 ). 
     When referring to  FIGS. 4 and 5 , the path forming member  80  includes a path portion  80   a , a pair of arm portions  80   b , and a unit to be regulated  80   c . The upper face side of the path portion  80   a  in the Z axis direction which is formed in a flat plate shape configures a part of the second medium transport path  78 . The pair of arm portions  80   b  protrudes from both end portions in the X axis direction in  FIGS. 4 and 5  to the −Y direction side in  FIGS. 4 and 5  in the path portion  80   a . The unit to be regulated  80   c  is provided at a tip end of each of the arm portions  80   b , that is, an end portion on the −Y direction side. 
     In addition, a rotating axis  90  is provided at an end portion of the path portion  80   a  on the +Y direction side in  FIGS. 4 and 5 . The rotating axis  90  is attached to the support plate  65  on the apparatus main body  12  side, and rotates the path forming member  80  with respect to the support plate  65 . 
     In addition, a pair of regulation units  96  (refer to  FIG. 4 ) which has a concave shape is provided on a base  94  in a mounting region  92  of the medium accommodating unit  20  with a gap therebetween in the X axis direction, in the apparatus main body  12 . The regulation unit  96  is provided at a position at which the regulation unit  96  engages with a unit to be regulated  80   c  of the path forming member  80  when the path forming member  80  rotates by having the rotating axis  90  as a fulcrum. 
     In addition, though it is not illustrated, a path forming member maintaining unit is provided on a lower face  76   a  of the paper guiding unit  76 . The path forming member maintaining unit engages with the unit to be regulated  80   c , and maintains the first state of the path forming member  80  when the path forming member  80  is in the first state. In addition, when the engaged state of the path forming member maintaining unit and the unit to be regulated  80   c  is released, the path forming member  80  rotates by having the rotating axis  90  as a fulcrum due to its own weight, and the unit to be regulated  80   c  and the regulation unit  96  are engaged, thereby entering the second state (refer to  FIGS. 5 and 6 ), when a lever (not shown) which is provided on the lower face  76   a  of the paper guiding unit  76  is operated. 
     In addition, when the path forming member  80  is switched to the first state from the second state, the path forming member maintaining unit engages with the unit to be regulated  80   c , and the first state of the path forming member  80  is maintained by the path forming member maintaining unit. In addition, the path forming member maintaining unit and the lever in the example have well-known configurations. 
     Accordingly, since the path forming member  80  which forms the second medium transport path  78  of the medium which is inserted through the medium reception unit  75  along with the medium reception unit  75  can expose the second medium transport path  78  to the medium discharging direction side (−Y direction side) by descending to a mounting region  92  from the upper part of the mounting region  92  of the medium accommodating unit  20 , it is possible to remove a jammed medium from the medium discharging direction side (−Y direction) when the medium is jammed in the second medium transport path  78  of the medium which is inserted through the medium reception unit  75 , that is, it is possible to easily remove the jammed medium. 
     In addition, when the path forming member  80  is switched to the second state (refer to  FIG. 6 ) from the first state (refer to  FIG. 1 ), the second transport driven roller  84  which configures the pair of second transport rollers  82 , and is provided in the path forming member  80  is separated from the second transport driving roller  86 . 
     In this manner, since the second transport driven roller  84  which configures the pair of second transport rollers  82  is separated from the second transport driving roller  86 , it is possible to release a nipped state of the medium due to the pair of second transport rollers  82 , and to further easily remove a jammed medium. 
     In addition, in the path forming member  80 , a displacement of the path forming member  80  from the medium discharging direction side to the opposite side, that is, from the −Y direction side to the +Y direction side in  FIGS. 5 and 6  is regulated when the unit to be regulated  80   c  and the regulation unit  96  are engaged during a time in the second state of the path forming member. 
     When the medium accommodating unit  20  is inserted into the mounting region  92  in a state in which the path forming member  80  descends to the mounting region  92 , that is, the second state (refer to  FIG. 6 ), there is a concern that the path forming member  80 , and the mounting structure unit of the path forming member (support plate  65 , rotating axis  90 , or the like) may be damaged. However, since the unit to be regulated  80   c  is provided in the path forming member  80 , the unit to be regulated  80   c  engages with the regulation unit  96  which is formed on the base  94  which configures the mounting region  92  of the medium accommodating unit  20  in the second state (refer to  FIG. 6 ), and a displacement of the path forming member  80  from the medium discharging direction side (−Y direction side in  FIG. 6 ) to the opposite side thereof (+Y direction side in  FIG. 6 ) is regulated, it is possible to avoid the above described damage.

     The second medium transport path  78  of the medium which is inserted through the medium reception unit  75  joins the medium transport path before reversing, or the medium transport path after reversing due to the first roller  38 . In addition, the transport path of the medium which is inserted through the medium reception unit  75  is joined at the position of the second roller  40  in the medium transport path before reversing due to the first roller  38 . 
     The transport path on the second medium support tray side  70  of the medium which is inserted through the second medium support tray  66 , which includes the second medium support tray  66  which supports the medium inserted into the apparatus main body  12  joins the second medium transport path  78  on which the medium which is inserted through the medium reception unit  75  is transported at the position of the first roller  38 , or the second roller  40 . 
     The medium accommodating unit  20  which is provided at a position lower than the recording head  58  in the vertical direction of the apparatus, and can handle the medium from the medium discharging direction side is included, and the medium which is sent out from the medium accommodating unit  20  reaches a position facing the recording head  58  through at least a part of the reversing transport path  54  which is formed by the first roller  38 . 
     At least a part of the region occupied by the reversing transport path  54  is located at the upper part of the medium accommodating unit  20 . 
     The second medium transport path  78  on which the medium which is inserted through the medium reception unit  75  is transported joins the first medium transport path  61  on which the medium which is sent out from the medium accommodating unit  20  is transported, and the pair of second transport rollers  82  which nips and transports the medium is provided on the upstream side in the medium transport direction of the position at which the second medium transport path joins the first medium transport path  61  on which the medium which is sent out from the medium accommodating unit  20  is transported, in the transport path on which the medium inserted through the medium reception unit is transported. 
     The medium accommodating unit  20  can be detached from the apparatus main body  12 . In the apparatus main body  12 , the path forming member  80  which forms the second medium transport path  78  of the medium which is inserted through the medium reception unit  75  is provided at the upper part of the mounting region  92  of the medium accommodating unit  20 , along with the medium reception unit  75 . The path forming member  80  is provided so as to switch between the first state in which the second medium transport path  78  of the medium which is inserted through the medium reception unit is formed along with the medium reception unit  75  and the second state in which the second medium transport path  78  of the medium which is inserted through the medium reception unit  75  is exposed to the −Y direction side due to descending of the path forming member from the upper part of the mounting region  92  to the mounting region  92  of the medium accommodating unit  20 . 
     On the second medium transport path  78 , the pair of second transport rollers  82  which nips and transports the medium is provided on the upstream side in the medium transport direction of the position at which the second medium transport path joins the first medium transport path  61 .
