Title: Recording apparatus

Description:
BACKGROUND 
     1. Technical Field 
     The present invention relates to a recording apparatus that performs recording on a medium. 
     2. Related Art 
     In recording apparatuses, representative examples of which are fax machines and printers, there are cases in which an opening/closing body is provided above a moving area of a carriage including a recording head. There are cases in which the opening/closing body is merely a cover, or is a scanner as described in JP-A-2013-56504 and JP-A-2006-23575. 
     In JP-A-2013-56504, a configuration is disclosed in which a state in which a scanner unit  12  is open is maintained by an arm-like member (a sliding member  77 ). Furthermore, JP-A-2006-23575 discloses a configuration in which a hinge is configured by a damper. 
     In a case in which the opening/closing body is, particularly, a heavy object such as a scanner described in JP-A-2013-56504 described above, when closing the opening/closing body, the arm-like member needs to be disengaged such that the operation thereof is laborious, and when closing the opening/closing body, if the opening/closing body is closed using its own weight, there is a concern that the impact may be large generating a collision noise that is unpleasant to the ear and that the opening/closing body may be broken. Accordingly, it is desirable that a damper, such as the one in JP-A-2006-23575, that damps the closing movement of the opening/closing body is provided. 
     However, providing a damper increases the size of the product. Furthermore, not only the size of the product itself, there is a call for a reduction in the space needed when using the product, specifically, there is a call for a product that allows the opening/closing body to be opened without the need to pull out the product even when the product is placed in an installation space low in height. 
     SUMMARY 
     An advantage of some aspects of the invention is that an increase in the size of the apparatus, and the space needed when the apparatus is used can be both suppressed with a configuration including an opening/closing body and a damper that apply damping force when the opening/closing body is closed. 
     According to an aspect of the invention, a recording apparatus includes a housing, an apparatus main body that constitutes an inside of the housing, the apparatus main body including a recording member that performs recording on a medium, a feed roller that feeds the medium, the medium being set at an inclined position, towards the recording member, an opening/closing body that opens/closes a portion above an area in which the recording member is disposed, and a damper that applies damping force to the opening/closing body when the opening/closing body is closed. In the recording apparatus, the opening/closing body and the damper are attached to the apparatus main body through an attaching member disposed at an area above the feed roller. 
     There is a lot of space area above the feed roller that feeds the medium, which is set in an inclined position, towards the recording member. Accordingly, in the present aspect, the opening/closing body and the damper are attached to the apparatus main body through the attaching member disposed in the area above the feed roller. Accordingly, an increase in the size of the apparatus can be suppressed with the above. 
     Furthermore, since the attaching member is positioned above the feed roller that feeds the medium, which is set in an inclined position, towards the recording member, assuming that a horizontal direction extending along the feeding direction of the medium sent out from the feed roller is an apparatus depth direction, in the apparatus depth direction, the attaching member is positioned not at the edge portion of an apparatus rear side but at a position that is on an apparatus front side (the recording head side) with respect to the edge portion. 
     Furthermore, since the opening/closing body is attached in an openable/closable manner through the attaching member in between, a rotational center of the opening/closing body is also positioned at where the attaching member is positioned. In other words, the rotational center of the opening/closing body is also positioned not at the edge portion of the apparatus rear side but at a position that is on an apparatus front side with respect to the edge portion. 
     With the above, the distance between the rotational center of the opening/closing body and the rotation free edge becomes smaller, and the height of the rotation free edge of the opening/closing body can be reduced when the opening/closing body is opened. Accordingly, even when the apparatus is installed in an installation space that is low in height, the opening/closing body can be opened without pulling out the apparatus from the installed space, or even when the opening/closing body cannot be opened completely, a sufficient opening amount can be obtained, and user-friendliness can be improved. 
     It is preferable that the recording apparatus further include a carriage that includes the recording head constituting the recording member, the carriage reciprocating in an apparatus width direction, a center frame positioned between a moving area of the carriage and an area in which the feed roller is disposed, the carriage being provided so as to extend in a moving direction of the carriage, and two side frames provided at two sides of the center frame, in which the attaching member is fixed to the two side frames. 
     According to the above, since the attaching member is fixed to the two side frames provided at the two sides of the center frame, the rigidity of the frame body constituted by the center frame and the two side frames can be increased. 
     It is preferable that the recording apparatus further include a carriage that includes the recording head constituting the recording member, the carriage reciprocating in an apparatus width direction, and a center frame positioned between a moving area of the carriage and an area in which the feed roller is disposed, the carriage being provided so as to extend in a moving direction of the carriage, in which at least a portion of a pivot shaft of the opening/closing body and at least a portion of the damper is positioned above the center frame. 
     According to the above, since at least a portion of the pivot shaft of the opening/closing body and at least a portion of the damper are positioned above the center frame provided so as to extend in the moving direction of the carriage, the occupying area of the center frame and the occupying areas of the pivot shaft and the damper do not completely superimpose on each other in the apparatus depth direction; accordingly, the size in the apparatus depth direction can be suppressed. 
     It is preferable that the recording apparatus further include a carriage that includes the recording head constituting the recording member, the carriage reciprocating in an apparatus width direction, and a center frame positioned between a moving area of the carriage and an area in which the feed roller is disposed, the carriage being provided so as to extend in a moving direction of the carriage, in which at least a portion of the attaching member is positioned above the center frame. 
     According to the above, since at least a portion of the attaching member is positioned above the center frame provided so as to extend in the moving direction of the carriage, the occupying area of the center frame and the occupying area of the attaching member in the apparatus depth direction do not completely superimpose on each other in the height direction; accordingly, the size in the apparatus depth direction can be suppressed. 
     It is preferable that the attaching member be fixed to the center frame in the above recording apparatus that further includes the carriage that includes the recording head constituting the recording member, the carriage reciprocating in the apparatus width direction, and the center frame positioned between the moving area of the carriage and the area in which the feed roller is disposed, the carriage being provided so as to extend in the moving direction of the carriage, in which at least a portion of the attaching member is positioned above the center frame. 
     According to the above, in the configuration in which the attaching member is fixed to the center frame, suppression in the size in the apparatus depth direction can be achieved. 
     It is preferable in the recording apparatus, the opening/closing body include a main body portion and an arm portion that connects the main body portion and a rotational center of the main body portion and the opening/closing body, in which a top surface member constituting an apparatus upper surface together with the opening/closing body is provided above the attaching member, and in which the arm portion has a shape that avoids an edge portion of the top surface member when the opening/closing body is opened/closed. 
     According to the above, since the arm portion, which connects the main body portion of the opening/closing body and the rotational center, has the shape that avoids the edge portion of the top surface member when the opening/closing body is opened/closed, the main body portion and the edge portion of the top surface member can be made to be closer to each other. As a result, in a state in which the opening/closing body is closed, the gap between the main body portion and the edge portion of the top surface member can be made smaller, the entering of dust and the like into the apparatus through the gap can be suppressed, and the appearance of the apparatus can be improved. 
     It is preferable that a carriage that includes the recording head constituting the recording member, the carriage reciprocating in an apparatus width direction, and a center frame positioned between a moving area of the carriage and an area in which the feed roller is disposed, the carriage being provided so as to extend in a moving direction of the carriage, in which at least a portion of the attaching member is positioned above the center frame, be included in the above recording apparatus according to the first aspect, in which the opening/closing body includes the main body portion and the arm portion that connects the main body portion and the rotational center of the main body portion and the opening/closing body, in which the top surface member constituting the apparatus upper surface together with the opening/closing body is provided above the attaching member, and in which the arm portion has the shape that avoids the edge portion of the top surface member when the opening/closing body is opened/closed. 
     According to the above, since at least a portion of the arm portion is positioned above the center frame positioned between the moving area of the carriage and the area in which the feed roller is disposed, the occupying area of the center frame and the occupying area of the arm portion in the apparatus depth direction do not completely superimpose on each other; accordingly, the size in the apparatus depth direction can be suppressed. 
     It is preferable that a guide frame on a recording member side with respect to the center frame, the guide frame guiding the carriage in the moving direction, in which an upper end portion of the guide frame is at a position that is higher than an upper end portion of the center frame, and in which at least a portion of the arm portion is, in a height direction, positioned inside a step formed between the upper end portion of the guide frame and the upper end portion of the center frame, be included in the above recording apparatus in which a carriage that includes the recording head constituting the recording member, the carriage reciprocating in an apparatus width direction, and a center frame positioned between a moving area of the carriage and an area in which the feed roller is disposed, the carriage being provided so as to extend in a moving direction of the carriage, in which at least a portion of the attaching member is positioned above the center frame. 
     According to the above, since at least a portion of the arm portion is disposed inside the step formed by the upper end portion of the guide frame and the upper end portion of the center frame in the height direction, an increase in the size of the apparatus can be suppressed by effective use of the space. 
     It is preferable at least a portion of the attaching member is positioned above the feed roller in either one of the recording apparatuses described above. 
     According to the above, in the configuration in which at least a portion of the attaching member is positioned above the feed roller, functions and effects similar to those described above can be obtained. 
     It is preferable that a holding member that is attached to the attaching member, and that, in a state in which the holding member is attached to the attaching member, holds the damper be included in either one of the recording apparatuses described above. 
     According to the above, since a holding member that is attached to the attaching member and that, in a state in which the holding member is attached to the attaching member, holds the damper is included, the damper can be prevented from falling off when an assembly, which is formed by attaching the damper to the attaching member, is mounted on the apparatus main body; accordingly, the efficiency of the assembly work is improved.

     Outline of Medium Transport Path 
     Referring to  FIG. 2 , a medium transport path  28  will be described. The two-dot chain line to which a reference sign P- 1  is attached in  FIG. 2  depicts a route of the medium that is transported along the medium transport path  28  from the medium accommodating cassette  18  to the discharge tray  16 . A pickup roller  30 , an inverting roller  32 , a transport roller pair  34 , a recording head  36  serving as a “recording member”, and a discharge roller pair  38  are disposed in the apparatus main body  11  in that order along the medium transport path  28 . 
     The pickup roller  30  is provided on the +Z direction side of the medium accommodating cassette  18 , and is pivotable about the pivot shaft  40  serving as a rotation fulcrum. The pickup roller  30  coming in contact with the medium accommodated in the medium accommodating cassette  18  transports the uppermost medium, among the mediums accommodated in the medium accommodating cassette  18 , downstream in a transport direction along the medium transport path  28 . 
     The medium sent out from the medium accommodating cassette  18  is warped and inverted by the inverting roller  32  and is sent to the transport roller pair  34  on the downstream side in the transport direction. The transport roller pair  34  sends the medium that has been sent from the inverting roller  32  to an area that opposes the recording head  36 . The recording head  36  is provided under the carriage  42  and is capable of ejecting ink in the −Z direction. The carriage  42  is capable of reciprocating inside the apparatus main body  11  in the X-axis direction. The recording head  36  ejects ink onto the medium that has been sent thereto by the transport roller pair  34  and performs recording on a recording surface of the medium. The medium on which recording has been performed is nipped between the discharge roller pair  38  provided downstream of the recording head  36  in the transport direction, and is discharged towards the discharge tray  16  projecting towards the apparatus front side. 
     Referring to  FIG. 2 , the dot and dash line attached with the reference sign P- 2  depicts a transport path of the medium transported from the feed port  25  towards the recording head  36 . The feed port  25  is exposed by opening the rear feed port cover  24  with respect to the apparatus main body  11 . The medium can be inserted into the apparatus main body  11  through the feed port  25 . A medium supporting portion  27  is provided downstream of the feed port  25  in the medium transport direction. The medium supporting portion  27  supports the medium, which has been inserted through the feed port  25 , with the medium in an inclined position. Note that the medium supporting portion  27  in the present exemplary embodiment is, as an example, configured as a hopper that is capable of swinging in directions in which the hopper comes in contact with and is separated from the feed roller  26  in a downstream area in the medium transport direction. 
     The feed roller  26  is provided downstream of the medium supporting portion  27  in the medium transport direction. A separating roller  44  is provided on the −Z axis direction side of the feed roller  26  and at a position opposing the feed roller  26 . 
     The medium supported by the medium supporting portion  27  while in an inclined position is nipped between the feed roller  26  and the separating roller  44 , and is sent to the transport roller pair  34 . The transport roller pair  34  sends the medium that has been sent from the feed port  25  to the area that opposes the recording head  36 . 
     Subsequently, recording is performed with the recording head  36  on the medium that has been sent to the above area, and the medium is discharged towards the discharge tray  16  with the discharge roller pair  38 .

The ink cartridges are mounted in the carriage  42  in such a manner that each ink cartridge is positioned so that the longitudinal direction thereof extends in the X-axis direction. Moreover, the plurality of ink cartridges are mounted in the carriage  42  so that the ink cartridges are aligned in the Y-axis direction. 
     Referring to  FIGS. 4 and 5 , a cover assembly  46  is attached on the upper portion of the apparatus main body  11 . The cover assembly  46  includes the cover  22 , an attaching member  48 , a plurality of dampers  50 , and a pivot shaft  52 . 
     Referring to  FIG. 5 , a main body portion  22   a  that is formed in a planer manner and that is capable of covering a portion above the apparatus main body  11 , and a plurality of arm portions  22   c  that, in an edge portion  22   b  (the edge portion on the −Y-axis direction side in  FIG. 4 , and the edge portion on the −Z-axis direction side in  FIG. 5 ) of the main body portion  22   a  on the attaching member  48  side, project from the main body portion  22   a  are formed in the cover  22 . The plurality of arm portions  22   c  are appropriately disposed at intervals in the X-axis direction. 
     Referring to  FIGS. 8 and 9 , the arm portions  22   c  on the +Y direction side of the edge portion  22   b  of the main body portion  22   a  on the attaching member  48  side (the lower portion of the edge portion  22   b  when the cover  22  is in the closed position) each, while being projected, extend towards the attaching member  48  side (the −Z direction in  FIGS. 8 and 9 ), and changing the extended direction, distal end portions  22   d  thereof each extends towards the −Y direction side. The pivot shaft  52  is inserted in the distal end portions  22   d . Note that in  FIGS. 8 and 9 , the cover  22  is in the open position with respect to the attaching member  48 . 
     Referring to  FIG. 6 , the attaching member  48  is provided so as to extend in the X-axis direction, and includes a base body portion  48   a  that is formed in a box shape that is open on the +Z direction side. A plurality of damper attaching portions  48   b  are provided at an edge portion of the base body portion  48   a  on the +Y-axis direction side at appropriate intervals in the X-axis direction. Moreover, bearings  48   c  are, at an edge portion of the base body portion  48   a  on the +Y-axis direction side, provided at both edge portions in the X-axis direction. 
       FIG. 7  illustrates the damper  50  according to the present exemplary embodiment. Each damper  50  according to the present exemplary embodiment includes, as an example, a damper main body  50   a , a rib  50   b , and a rotor  50   c . The damper main body  50   a  is formed in a column shape, for example. The rib  50   b  projects from the damper main body  50   a  in a radial direction of the damper main body  50   a . The rotor  50   c  is a rod-shaped member that extends in the X-axis direction, in which one end side is inserted in the damper main body  50   a  and the other end projects from the damper main body  50   a.    
     In the present exemplary embodiment, each damper  50  is a known rotary damper, for example. A liquid, for example, is filled between the damper main body  50   a  and the rotor  50   c  so that, with the viscous resistance of the liquid (oil or the like), damping force (braking force) acts on the movement of the rotor  50   c  rotating relative to the damper main body  50   a . Note that while, as an example, liquid is used in the damper  50 , gas, or an urging member such as a spring may be used. Furthermore, not only a rotary damper, the damper  50  may be a vibration damper or the like that applies damping force (braking force) to the rotational movement. 
     Referring to  FIGS. 8 and 9 , an assembling process of the cover assembly  46  will be described. After positioning between the distal end portions  22   d  of the arm portions  22   c  of the cover  22  and the bearings  48   c  of the attaching member  48  is performed, the pivot shaft  52  is inserted through the distal end portions  22   d  and the bearings  48   c  to pivotably connect the cover  22  and the attaching member  48  to each other. 
     An attaching process of the dampers  50  will be described next. Referring to  FIG. 8 , a recess  48   d  is provided in the damper attaching portions  48   b . The shape of the recess  48   d  corresponds to the shape of the rib  50   b  of the damper  50  ( FIG. 14 ). For example, the damper  50  is slid from the −X direction side of the damper attaching portions  48   b  towards the damper attaching portions  48   b  side. In so doing, the damper  50  is inserted into the damper attaching portions  48   b  while positioning is performed so that the rib  50   b  fits into the recess  48   d . Moreover, the rotor  50   c  of the damper  50  is press fitted into the distal end portion  22   d  of the arm portion  22   c . With the above, the assembling of the cover assembly  46  is completed. Note that in the present exemplary embodiment, a plurality of dampers  50  are disposed between the cover  22  and the attaching member  48 . As a result, damping force (braking force) of the plurality of dampers  50  acts between the cover  22  and the attaching member  48 . 
     Attaching Cover Assembly to Apparatus Main Body 
     Referring to  FIGS. 10 and 11 , the apparatus main body  11  includes a center frame  54  ( FIG. 11 ) and side frames  56 A and  56 B. As illustrated in  FIG. 2 , the center frame  54  is disposed between the feed roller  26  and the carriage  42  in the Y-axis direction. The center frame  54  is provided so as to extend in the X-axis direction that is the moving direction of the carriage  42 . The side frames  56 A and  56 B are connected to the two sides of the center frame  54  in the X-axis direction. In the present exemplary embodiment, the cover assembly  46  is attached to the apparatus main body  11  and above the apparatus main body  11  with the side frames  56 A and  56 B interposed therebetween. 
     Specifically, referring to  FIG. 11 , attaching portions  48   e  are provided on both edge portions in the X-axis direction of the base body portion  48   a  of the attaching member  48  of the cover assembly  46 . The attaching portions  48   e  are configured so that fastening members  58  ( FIG. 10 ) can be inserted therein. As illustrated in  FIGS. 10 and 11 , the attaching member  48  is fixed to the side frames  56 A and  56 B with the fastening members  58  while the attaching portions  48   e  are abutted against the upper portions of the side frames  56 A and  56 B. As a result, the side frames  56 A and  56 B are not only fixed to the center frame  54  but are also fixed to the attaching member  48 ; accordingly, the rigidity of a frame body constituted by the center frame  54  and the side frames  56 A and  56 B can be increased. Note that while the fastening members  58  according to the present exemplary embodiment are, as an example, screws, the fastening members  58  may be bolts or the like. 
     Position of Attaching Member with Respect to Apparatus Main Body 
     Referring to  FIGS. 2 and 14 , a relationship between the cover  22  and the attaching member  48 , and the apparatus main body  11  in a state in which the cover assembly  46  is attached to the apparatus main body  11  will be described. Referring to  FIG. 14 , a guide frame  60  is provided on the +Y-axis direction side of the center frame  54 . The guide frame  60  is provided so as to extend in the X-axis direction and guides the motion of the carriage  42  in the X-axis direction. In the present exemplary embodiment, a height of an upper end portion  60   a  of the guide frame  60  in the Z-axis direction is set higher than a height of an upper end portion  54   a  of the center frame  54 . 
     Referring to  FIG. 2 , the attaching member  48  of the cover assembly  46  is disposed in an area above (the +Z direction side) the feed roller  26  in the Y-axis direction. Furthermore, referring to  FIG. 14 , at least a portion of the attaching member  48 , specifically, the damper attaching portions  48   b  and the bearings  48   c , are positioned above (on the +Z direction side of) the center frame  54  in the Y-axis direction. Moreover, at least a portion of each damper  50 , at least a portion of the pivot shaft  52  (the broken line portion in  FIG. 14 ), and at least a portion of each arm portion  22   c  are positioned above (on the +Z direction side of) the center frame  54 . 
     With the above, an occupying area of the center frame  54  and occupying areas of the attaching member  48 , the dampers  50 , the pivot shaft  52 , and the arm portions  22   c  can be made to overlap each other in the Y-axis direction; accordingly, the size in the Y-axis direction can be suppressed. 
     Referring to  FIG. 14 , the two-dot chain line to which reference numeral  22 - 1  is attached illustrates a state in which the cover  22  is closed with respect to the apparatus main body  11 . Reference numeral  22   b - 1  illustrates the edge portion  22   b  in a state in which the cover  22  is closed, and the reference numeral  22   c - 1  illustrates the arm portions  22   c  in a state in which the cover  22  is closed. In a state in which the cover  22  is closed with respect to the apparatus main body  11 , at least a portion of each arm portion  22   c  (see the two-dot chain line to which the reference numeral  22   c - 1  is attached) is, in the Z-axis direction, positioned inside a step formed by the upper end portion  54   a  of the center frame  54  and the upper end portion  60   a  of the guide frame  60 . As a result, a portion of each arm portion  22   c  can be disposed while using the step; accordingly, the space can be used efficiently and the size in the Z-axis direction can be suppressed. 
     Moreover, in a state in which the cover  22  is closed, the arm portions  22   c  are each formed so as to have a shape avoiding a front edge portion  20   a  of the top surface member  20 . Specifically, each arm portion  22   c  extends in the −Y direction from below the edge portion  22   b  and changes the extending direction towards the +Z direction side so as to be attached to the pivot shaft  52 . In as state in which the cover  22  is closed, each arm portions  22   c  avoids the front edge portion  20   a , and is positioned on the −Z direction side of the front edge portion  20   a . When the cover  22  is pivoted from a state in which the cover  22  is closed (the two-dot chain line portion to which the reference numeral  22 - 1  is attached) to a state in which the cover  22  is open (a solid line portion in  FIG. 14 ), the arm portions  22   c  and the front edge portion  20   a  do not interfere with each other since the arm portions  22   c  are each formed in a shape that avoids the front edge portion  20   a  of the top surface member  20 . 
     As a result, the main body portion  22   a  of the cover  22  can be configured closer to the front edge portion  20   a  of the top surface member  20 , and a gap  62  ( FIG. 14 ) between the main body portion  22   a  and the front edge portion  20   a  can be made smaller. With the above, entering of dust into the apparatus main body  11  through the gap  62  can be prevented or reduced. Furthermore, since the gap  62  can be made smaller, the top surface member  20  and the cover  22  that form the upper surface of the apparatus main body  11  can appear as if the top surface member  20  and the cover  22  are integrated; accordingly, the appearance of the apparatus can be improved. 
     As illustrated in  FIGS. 2, 3, and 14 , compared with a case in which the pivot shaft of the cover  22  is provided at an edge portion of the apparatus main body  11  on the −Y direction side, the pivot shaft  52  of the cover  22  is positioned closer to the front edge portion  20   a  of the top surface member  20  in the Y-axis direction. Accordingly, compared with the case in which the pivot shaft of the cover  22  is provided at an edge portion of the apparatus main body  11  on the −Y direction side, the length of the main body portion  22   a  of the cover  22  in the Y-axis direction can be decreased. Specifically, the length from a front edge portion (a free edge portion)  22   e  of the cover  22  to the pivot shaft  52  in the Y-axis direction becomes shorter. With the above, the height of the front edge portion  22   e  of the cover  22  in the Z-axis direction can be made shorter when the cover  22  is switched to an open state ( FIG. 3 ) from a closed state ( FIG. 1 ). 
     As a result, even in a case in which the printer  10  is installed in a low installing space, the cover  22  can be opened/closed without pulling out the printer  10  from the installing space. Alternatively, even if the cover  22  cannot be fully opened, since a sufficient opening amount of the cover  22  is obtained, the user can easily put a hand inside the moving area of the carriage  42  in the apparatus main body  11  and easily remove the medium jammed inside the moving area. 
     Referring to  FIG. 15 , a plurality of ribs  20   b  are provided in the top surface member  20 . In a state in which the cover assembly  46  and the top surface member  20  are attached to the apparatus main body  11 , the plurality of ribs  20   b  are each disposed at a position on the opposite side with respect to the side on which the rotor  50   c  of the corresponding damper  50  is provided. With the above, the ribs  20   b  prevent the dampers  50  from falling out from the damper attaching portions  48   b  and the distal end portions  22   d  of the arm portions  22   c.    
     Cable Wiring Around Cover Assembly 
     Referring to  FIGS. 12, 13, and 15 , cable wiring around the cover assembly  46  of the apparatus main body  11  will be described. A sheet metal member  64  is provided so as to cover an underside of the base body portion  48   a  of the attaching member  48  and an edge portion of the base body portion  48   a  on the −Y direction side. The sheet metal member  64  is formed of a metal material. 
     Referring to  FIG. 12 , a control unit (not shown) is provided on the side frame  56 B on the +X direction side. Cable  66  extending from the control unit is adhered on a rear surface (a surface on the −Y direction side)  64   a  of the sheet metal member  64  and extends in the −X-axis direction. After extending to a position corresponding to the feed roller  26  in the X-axis direction, the cable  66  is connected to a medium detection sensor (not shown) provided inside the apparatus main body  11 . 
     Cable  68  is a length of distribution cable that extends inside the apparatus main body  11  from a waste liquid tank (not shown) disposed on the side frame  56 A side to the control unit (not shown). The cable  68  passes a portion above the side frame  56 A, extends in the +X-axis direction after passing between, as illustrated in  FIG. 13 , the base body portion  48   a  of the attaching member  48  and the sheet metal member  64  in the Y-axis direction, and is connected to the control unit (not shown). Note that in the present exemplary embodiment, as an example, the cables  66  and  68  are each a flexible flat cable (FFC) for signal transmission. In the exemplary embodiment, since the cables  66  and  68  are wired along the sheet metal member  64 , noise created in the cables  66  and  68  can be reduced. 
     Second Exemplary Embodiment 
     Referring to  FIGS. 16 to 18 , a second exemplary embodiment will be described. The second exemplary embodiment is different from the first exemplary embodiment in that the second exemplary embodiment includes a holding member  70 . Note that the configurations of the cover  22 , the attaching member  48 , and the dampers  50  are similar to those of the first exemplary embodiment; accordingly, description thereof is omitted. 
     Referring to  FIG. 16 , the holding member  70  covers a portion above the base body portion  48   a  of the attaching member  48 . Moreover, as illustrated in  FIGS. 17 and 18 , a plurality of ribs  70   a  that extend towards the +Y direction side are provided in the holding member  70  at appropriate intervals in the X-axis direction. In a state in which the holding member  70  is attached to the attaching member  48 , the ribs  70   a  are each provided at a position on the opposite side with respect to the side in which the rotor  50   c  of the corresponding damper  50  is provided. With the above, the ribs  70   a  prevent the dampers  50  from falling out from the damper attaching portions  48   b  and the distal end portions  22   d  of the arm portions  22   c.    
     The cover  22 , the attaching member  48 , the dampers  50 , and the holding member  70  can be configured as a cover assembly  72  by attaching the holding member  70  to the attaching member  48  after the dampers  50  are attached to the attaching member  48 . When the cover assembly  72  is mounted on the apparatus main body  11 , the holding member  70  prevents the dampers  50  from falling out; accordingly, work of mounting the cover assembly  72  on the apparatus main body  11  is facilitated. 
     In the present exemplary embodiment as well, the cable  66  is a signal cable that connects the control unit (not shown) and the medium detection sensor (not shown) to each other. In the exemplary embodiment, the cable  66  extended out from the control unit is adhered to a rear edge portion  70   b  of the holding member  70  that covers the upper portion of the base body portion  48   a  of the attaching member  48 , is extended in the −X-axis direction, and is connected to the medium detection sensor (not shown). 
     Meanwhile, similar to the first exemplary embodiment, the cable  68  extends from the waste liquid tank (not shown) disposed on the side frame  56 A side to the control unit (not shown). In the present exemplary embodiment, the cable  68  passes a portion above the side frame  56 A, extends in the +X-axis direction at an upper surface  70   c  of the holding member  70 , and is connected to the control unit (not shown). Note that in the present exemplary embodiment as well, the holding member  70  is formed of a metal material. Accordingly, since the cables  66  and  68  are wired along the holding member  70 , noise created in the cables  66  and  68  can be reduced. 
     Modifications of First Exemplary Embodiment and Second Exemplary Embodiment 
     (1) Each exemplary embodiment is configured so that the attaching member  48  is connected to the side frames  56 A and  56 B. However, instead of the above configuration, the attaching member  48  may be attached to the center frame  54 . 
     (2) In each exemplary embodiment, the cables  66  and  68  are wired along the sheet metal member  64  or the holding member  70 . However, instead of the above configuration, a cut-out portion may be provided in the base body portion  48   a  of the attaching member  48  so that communication is established in the X-axis direction in  FIG. 13 , and the cables  66  and  68  may be wired so as to extend in the X-axis direction through the cut-out portion. The above configuration allows the space inside the base body portion  48   a  to be used effectively, and a space for laying the cables  66  and  68  to be provided separately; accordingly, the space of the apparatus can be saved. 
     The above description will be Summarized. The printer  10  includes the recording head  36  that performs recording on a medium, the feed roller  26  that feeds the medium, which is set in an inclined position, towards the recording head  36 , the cover  22  that opens/closes the portion above the area in which the recording head  36  is disposed, and the dampers  50  that apply damping force to the cover  22  when the cover  22  is closed. The cover  22  and the dampers  50  are attached through the attaching member  48  disposed in an area above the feed roller  26 . 
     There is a lot of space area above the feed roller  26  that feeds the medium, which is set in an inclined position, towards the recording head  36 . Accordingly, in each exemplary embodiment, the cover  22  and the dampers  50  are attached through the attaching member  48  that is disposed in the area above the feed roller  26 . Accordingly, an increase in the size of the printer  10  can be suppressed with the above. 
     Furthermore, since the attaching member  48  is positioned above the feed roller  26  that feeds the medium, which is set in an inclined position, towards the recording head  36 , assuming that the direction extending along the feeding direction of the medium sent out from the feed roller  26  is an apparatus depth direction (the Y-axis direction), in the apparatus depth direction (the Y-axis direction), the attaching member  48  is positioned not at the edge portion of an apparatus rear side (the −Y-axis direction side) but at a position that is on an apparatus front side (+Y-axis direction side, or the recording head  36  side) with respect to the edge portion. 
     Furthermore, since the cover  22  is attached in an openable/closable manner through the attaching member  48  in between, the pivot shaft  52  that is a rotational center of the cover  22  is also positioned at where the attaching member  48  is positioned. In other words, the pivot shaft  52  that is the rotational center of the cover  22  is also positioned not at the edge portion of the apparatus rear side (the −Y-axis direction side) but at a position that is on an apparatus front side (+Y-axis direction side) with respect to the edge portion. 
     With the above, since the distance between the pivot shaft  52  that is the rotational center of the cover  22  and the front edge portion  22   e  that is a rotation free edge of the cover  22  decreases, the length from the pivot shaft  52  of the cover  22  to the front edge portion  22   e  becomes shorter, and the height of the front edge portion  22   e  of the cover  22  when the cover  22  is open can be reduced. Accordingly, even when the printer  10  is installed in an installation space that is low in height, the cover  22  can be opened without pulling out the apparatus from the installed space, or even when the cover  22  cannot be opened completely, a sufficient opening amount can be obtained, and user-friendliness can be improved. 
     The printer  10  includes a carriage  42  that includes the recording head  36  constituting the recording member and that reciprocates in the apparatus width direction (X-axis direction), the center frame  54  that is positioned between the moving area of the carriage  42  and the area in which the feed roller  26  is disposed and that is provided so as to extend in the moving direction of the carriage  42 , and the two side frames  56 A and  56 B that are provided at the two sides of the center frame  54 . The attaching member  48  is fixed to the two side frames  56 A and  56 B. With such a configuration, the rigidity of the frame body constituted by the center frame  54  and the two side frames  56 A and  56 B can be increased. 
     The printer  10  includes a carriage  42  that includes the recording head  36  constituting the recording member and that reciprocates in the apparatus width direction (X-axis direction), and the center frame  54  that is positioned between the moving area of the carriage  42  and the area in which the feed roller  26  is disposed and that is provided so as to extend in the moving direction of the carriage  42 . At least a portion of the pivot shaft  52  of the cover  22  and at least a portion of each damper  50  are positioned above the center frame  54 . With such a configuration, the occupying area of the center frame  54  and the occupying areas of the pivot shaft  52  and the dampers  50  are not completely superimposed on each other in the apparatus depth direction (Y-axis direction), and the size in the apparatus depth direction (Y-axis direction) can be suppressed. 
     The printer  10  includes a carriage  42  that includes the recording head  36  constituting the recording member and that reciprocates in the apparatus width direction (X-axis direction), and the center frame  54  that is positioned between the moving area of the carriage  42  and the area in which the feed roller  26  is disposed and that is provided so as to extend in the moving direction of the carriage  42 . At least a portion of the attaching member  48  is positioned above the center frame  54 . With such a configuration, the occupying area of the center frame  54  and the occupying area of the attaching member  48  are not completely superimposed on each other in the apparatus depth direction (Y-axis direction), and the size in the apparatus depth direction (Y-axis direction) can be suppressed. 
     The attaching member  48  is fixed to the center frame  54 . 
     The cover  22  includes the arm portions  22   c  that connect the main body portion  22   a , and the pivot shaft  52  that is the rotational center of the main body portion  22   a  and the cover  22  to each other. The top surface member  20  constituting the apparatus upper surface together with the cover  22  is provided above the attaching member  48 . The arm portions  22   c  each have a shape that avoids the front edge portion  20   a  of the top surface member  20  when the cover  22  is opened/closed. 
     With such a configuration, the main body portion  22   a  and the front edge portion  20   a  of the top surface member  20  can be configured closer to each other. As a result, in a state in which the cover  22  is closed, the gap  62  between the main body portion  22   a  and the front edge portion  20   a  of the top surface member  20  can be made smaller, the entering of dust and the like into the apparatus main body  11  through the gap  62  can be suppressed, and the appearance of the printer  10  can be improved. 
     The printer  10  includes a carriage  42  that includes the recording head  36  constituting the recording member and that reciprocates in the apparatus width direction (X-axis direction), and the center frame  54  that is positioned between the moving area of the carriage  42  and the area in which the feed roller  26  is disposed and that is provided so as to extend in the moving direction of the carriage  42 . At least a portion of each arm portion  22   c  is positioned above the center frame  54 . With such a configuration, the occupying area of the center frame  54  and the occupying area of the arm portions  22   c  are not completely superimposed on each other in the apparatus depth direction (Y-axis direction), and the size in the apparatus depth direction can be suppressed. 
     The printer  10  includes the guide frame  60  on the recording head  36  side with respect to the center frame  54  in the apparatus depth direction (Y-axis direction). The guide frame  60  guides the carriage  42  in the moving direction (X-axis direction). The upper end portion  60   a  of the guide frame  60  is positioned at a position higher than the position of the upper end portion  54   a  of the center frame  54 , and at least a portion of each arm portion  22   c  is, in the height direction (Z-axis direction), positioned inside a step formed by the upper end portion  60   a  of the guide frame  60  and the upper end portion  54   a  of the center frame  54 . With such a configuration, an increase in the size of the apparatus can be suppressed through effective use of the space. 
     The feed member includes the feed roller  26  that feeds the medium, and at least a portion of the attaching member  48  is positioned above the feed roller  26 . 
     The printer  10  includes the holding member  70  that is attached to the attaching member  48 . In a state in which the holding member  70  is attached to the attaching member  48 , the holding member  70  holds the dampers  50 . With such a configuration, the dampers  50  can be prevented from falling off when the cover assembly  72  formed by attaching the dampers  50  to the attaching member  48  is mounted on the apparatus main body  11 ; accordingly, the efficiency of the assembly work is improved. 
     Furthermore, in the exemplary embodiments, the cover  22 , the attaching member  48 , and the dampers  50  according to the invention are applied to an ink jet printer that is an example of the recording apparatus; however, the cover  22 , the attaching member  48 , and the dampers  50  can be applied to any other general liquid ejection apparatus. 
     Herein, the liquid ejection apparatus is not limited to a recording apparatus such as a printer, a copying machine, or a facsimile machine that performs recording on a recording medium by using an ink jet recording head to eject ink from the recording head, but also includes an apparatus that ejects liquid, which meets the purpose of the apparatus and is provided in place of the ink, onto a medium to be ejected, which corresponds to the recording medium, from a liquid ejection head, which corresponds to the ink jet recording head, to deposit the liquid onto the medium to be ejected. 
     Other than the recording head described above, the liquid ejection head may include, for example, a color material ejection head that is used to manufacture color filters for liquid crystal displays and the like, an electrode material (conductive paste) ejection head that is used to form electrodes for organic EL displays, surface emitting displays (FED), and the like, a bio organic matter ejecting head used to manufacture biochips, and a sample ejection head serving as a precision pipette. 
     Note that the invention is not limited to the exemplary embodiments described above and may be modified in various ways that is within the scope of the claims. It goes without saying that the modifications are also included in the scope of the invention. 
     The entire invention of Japanese Patent Application No. 2017-073800, filed Apr. 3, 2017, is expressly incorporated by reference herein.
