Title: Recording device

Description:
The present application is based on, and claims priority from JP Application Serial Number 2021-185445, filed Nov. 15, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety. 
     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a recording device. 
     2. Related Art 
     Conventionally, large format inkjet printers have been known as recording devices. Some of such recording devices use a recording medium wound in a roll shape. For example, JP-A-2021-133527 discloses a recording device holding two roll bodies, which are before recorded and after recorded. 
     However, the recording device described in JP-A-2021-133527 has a problem that a wide installation space is required. Specifically, in the above-described recording device, a leg portion supports a housing, and each of the roll bodies is disposed in the front and the rear of the leg portion. Thus, a large installation space is required due to an increase in size in the front and the rear directions. In addition, when a new roll body is mounted, a space for the user to work behind is required. Furthermore, there is a problem that the appearance has many irregularities and thus improvement in design properties is difficult. 
     In contrast, in a case where the entirety of the device is formed as a rectangular parallelepiped housing and a printing unit, the leg portion, the roll body, and the like are accommodated in the housing, there is a problem in that mechanical strength of the recording device is easily reduced. Specifically, in the configuration described above, a side frame may be extended downward, and thus rigidity of the frame may be insufficient. In other words, there has been a demand for a recording device that has excellent design properties and mechanical strength and reduces the installation space. 
     SUMMARY 
     A recording device includes a recording unit, a support portion including a support face for supporting a recording medium on which recording is performed by the recording unit at a position facing the recording unit, a transport path for transporting the recording medium to the support portion, a recording medium holding unit for holding a roll body on which the recording medium is wound and supplying the recording medium to the transport path, and a frame for holding the recording unit, the support portion, the transport path, and the recording medium holding unit, wherein the frame includes a lower frame extending along a first direction and extending along a second direction intersecting the first direction, a pair of side frames extending along a third direction intersecting the first direction and the second direction and the second direction, each including a lower end fixed to the lower frame and upright in the third direction, and disposed at a predetermined interval in the first direction, and a base frame held between the pair of side frames and including four wall surfaces extending in the first direction, and functional components related to recording of the recording unit are disposed inside the four wall surfaces of the base frame.

     An input unit  59  is disposed on the upper surface  17  in the −X direction and the +Y direction. The input unit  59  is, for example, a touch panel type liquid crystal display device. The input unit  59  is electrically coupled to the control unit. In the input unit  59 , various types of operations of the recording device  10  are input, and various types of information of the recording device  10  are displayed. 
     The control unit includes a Central Processing Unit (CPU), a Read Only Memory (ROM), and a Random Access Memory (RAM). The control unit is electrically coupled to each component of the recording device  10 , and integrally controls the operation of the recording device  10 . The recording device  10  may be operated from an information device such as a personal computer via the control unit. 
     As illustrated in  FIG.  2   , in the recording device  10 , main components are disposed around a base frame  67 . The base frame  67  extends in the X direction. Here,  FIG.  2    is a cross-section taken along the YZ plane and dividing the duct  73 . The four leg portions  11  are disposed on the lower frame  65  forming the bottom surface  18 .

     The recording device  10  is installed on an installation surface S via the four leg portions  11  for supporting the lower frame  65 . The leg portions  11  are, for example, members such as casters or adjusters capable of supporting and fixing a heavy load. The leg portions  11  are not limited to four, and may be five or more. Both the casters and the adjusters may also be included. 
     In the recording device  10 , the recording medium  22  is transported from the recording medium holding unit  20  to the paper exit  53  described above through the transport path  40  and a position where the recording unit  30  and the support portion  31  are facing each other. 
     Although not illustrated, the recording medium holding unit  20  includes feeding mechanisms of recording mediums  22 , each corresponding to a respective one of the roll bodies  25   a  and  25   b . A user selects which recording medium  22  among the roll bodies  25   a  and  25   b  is to be used. The recording medium  22  is fed from the recording medium holding unit  20  to the rear side and the upper side and advances to the transport path  40 . 
     The transport path  40  transports the recording medium  22  to the support portion  31 . The transport path  40  is formed of lower face side path forming members  41   a  and  41   b , inclined surfaces  44   a  and  44   b , a rear face side path forming member  45 , and an upper face side path forming member  47 . For these members forming the transport path  40 , a material such as resin having a small coefficient of friction is employed so that the recording medium  22  slides on the material. Note that the lower face side path forming member  41   a  is an example of the lower face side path forming member of the present disclosure. 
     The transport path  40  includes an intermediate roller  42  and a transport roller  43  as transport rollers for transporting the recording medium  22  in the transport direction. In the intermediate roller  42  and the transport roller  43 , a material such as rubber or resin-based elastomer having a large coefficient of friction is used on a surface with which the recording medium  22  comes into contact. 
     The transport path  40  extends from the lower side to the upper side via the rear side with respect to the base frame  67 . In the transport path  40 , the lower face side path forming member  41   a  and the inclined surface  44   a  or the lower face side path forming member  41   b  and the inclined surface  44   b , the rear face side path forming member  45 , the intermediate roller  42 , the upper face side path forming member  47 , and the transport roller  43  are disposed in this order from the upstream toward the support portions  31  in the downstream. 
     The lower face side path forming members  41   a  and  41   b  and the inclined surfaces  44   a  and  44   b  are disposed on the lower side of the base frame  67 . The lower face side path forming member  41   a  and the inclined surface  44   a  are disposed corresponding to the roll body  25   a . The lower face side path forming member  41   b  and the inclined surface  44   b  are disposed corresponding to the roll body  25   b . Each of the lower face side path forming members  41   a  and  41   b  corresponds to a rear surface of a recording surface of a respective one of the recording mediums  22 , and each of the inclined surfaces  44   a  and  44   b  corresponds to the recording surface of a respective one of the recording mediums  22 . 
     The rear face side path forming member  45  is disposed on the rear side of the base frame  67 . The recording mediums  22  are transported to the upper side along the rear face side path forming member  45 . 
     The transport direction of the recording medium  22  is changed to the substantially +Y direction at the intermediate roller  42 . The intermediate roller  42 , the upper face side path forming member  47 , and the transport roller  43  are located on the upstream side in the transport direction of the recording medium  22  transported to a support face  31   s  of the support portion  31 , and are disposed on the upper side and closer to the rear side of the base frame  67 . 
     The intermediate roller  42  and the transport roller  43  are driven by a motor (not illustrated) to rotate counterclockwise in a side view from the −X direction, and transport the recording medium  22  downstream. The upper face side path forming member  47  is located between the intermediate roller  42  and the transport roller  43 , and guides the recording medium  22 . 
     The support portion  31  is disposed downstream of the transport roller  43  and on the upper side of the base frame  67 . The recording head  34  of the recording unit  30  is disposed on the upper side of the support portion  31 . The support portion  31  includes a negative pressure chamber  31   r , the support face  31   s , and a plurality of openings described below. The support face  31   s  supports the recording medium  22  at a position facing the recording unit  30 . At this position, recording is performed on the recording medium  22 . 
     The negative pressure chamber  31   r  is disposed on the lower side of the support face  31   s . The plurality of openings are provided on the support face  31   s , and communicate with the support face  31   s  from the inside of the negative pressure chamber  31   r . The support face  31   s  is disposed on the upper side of the negative pressure chamber  31   r  to face the recording unit  30  in the Z direction. 
     The recording device  10  includes a negative pressure mechanism  75  and a duct  73 . The negative pressure mechanism  75  is on the front side of the base frame  67 . The duct  73  is located inside the base frame  67  and is curved. One end of the duct  73  is coupled to the rear side of the negative pressure mechanism  75 , and the other end protrudes to the upper side from the base frame  67  to communicate with the negative pressure chamber  31   r.    
     The duct  73  allows the negative pressure chamber  31   r  and the negative pressure mechanism  75  to communicate with each other. The negative pressure mechanism  75  includes, for example, a suction fan and applies negative pressure to the negative pressure chamber  31   r . That is, the recording medium  22  is adsorbed to the support face  31   s  by the negative pressure generated by the negative pressure mechanism  75 . This can suppress .the occurrence of wrinkles and misalignment of the recording medium  22  in the support portion  31 . 
     The recording head  34  is located on the lower side of the carriage  33  and is disposed to face the support face  31   s . Although not illustrated, the recording head  34  includes an actuator, which is a driving means for ink discharging. Examples of the actuator include a piezoelectric element, an electro-mechanical conversion element for displacing a vibration plate by electrostatic adsorption, and an electro-thermal conversion element for ejecting ink droplets by gas bubbles generated by heating. 
     The carriage  33  is supported by a guide rail (not illustrated) of a main frame  61 . The main frame  61  has a quadrangular prism shape having a substantially rectangular cross-section. The main frame  61  is disposed on the upper side of the intermediate roller  42  with the height direction of the quadrangular prism being along the X direction. 
     The main frame  61  supports the carriage  33  of the recording unit  30  via the guide rail movably in the X direction. In other words, the carriage  33  is allowed to scan in the X direction by driving of the motor (not illustrated) while being supported by the main frame  61 . The recording medium  22  is transported while the carriage  33  is allowed to scan, and the ink is adhered to the recording medium  22  from the recording head  34 , and thus images, colors, texts, and the like are recorded on the recording medium  22  to produce a recorded matter. 
     The recording device  10  includes a maintenance tank  83  for collecting an ink ejected to be discarded on the support face  31   s  during borderless printing or the like. The maintenance tank  83  is disposed on the upper side and on the front side of the base frame  67 . Although not illustrated, a gutter portion is coupled to the maintenance tank  83  from the support face  31   s . The ink is guided from the support face  31   s  into the maintenance tank  83  via the gutter portion. An absorbent material for absorbing and retaining the ink is disposed inside the maintenance tank  83 . 
     A cutting portion  50  is disposed in the downstream of the support portion  31 . The cutting portion  50  cuts the recording medium  22  along the X direction at a desired position. The recording medium  22  is discharged as the recorded matter to the front side from the paper exit  53  described above. 
     As illustrated in  FIG.  3   , the frame  60  of the recording device  10  includes the main frame  61 , the base frame  67 , the lower frame  65 , a pair of side frames  62  and  63 , a sub-frame  69 , and a sub-base frame  68 . These are assembled to form the frame  60 . The frame  60  holds the recording unit  30 , the support portion  31 , the transport path  40 , and the recording medium holding unit  20  described above. 
     The lower frame  65  is located closer to the lowest side of the frame  60 . The lower frame  65  is a member elongated in the X direction and is along the X direction and extends along the Y direction. Although not illustrated, the lower frame  65  includes a plurality of ribs extending along the X direction and a bent portion. In the X direction, the length of the lower frame  65  is substantially equal to the length of the housing  12  of the recording device  10  described above. 
     Each of the pair of side frames  62  and  63  includes a lower end fixed to a surface on the upper side of the lower frame  65 , and is upright in the Z direction. When viewed from the Y direction, the side frame  62  is disposed in the +X direction, and the side frame  63  is disposed in the −X direction. The side frame  62  includes a first portion  62   a  and a second portion  62   b . The side frame  63  includes a first portion  63   a  and a second portion  63   b.    
     The first portions  62   a  and  63   a  extend in the Z direction and the Y direction. The second portion  62   b  is bent and extends from the first portion  62   a  in the X direction, in particular in the −X direction. The second portion  63   b  is bent and extends from the first portion  63   a  in the X direction, in particular in the +X direction. The pair of side frames  62  and  63  are disposed to face each other in the X direction with a predetermined gap therebetween. The predetermined gap is, for example, a distance longer than the length in the X direction of the roll body  25   a  described above. 
     Each of the four leg portions  11  is disposed overlapping one of the first portions  62   a  and  63   a  and the second portions  62   b  and  63   b  when viewed from the Z direction. Specifically, the leg portion  11  in the −X direction and on the front side overlaps the first portion  63   a , and the leg portion  11  in the −X direction and on the rear side overlaps the second portion  63   b . The leg portion  11  in the +X direction and on the front side overlap the first portion  62   a , and the leg portion  11  in the +X direction and on the rear side overlap the second portion  62   b.    
     As a result, the leg portions  11  are provided in positions where the lower frame  65  fixes the side frames  62  and  63 , and thus the lower frame  65  is reinforced by the side frames  62  and  63 , and deformation of the lower frame  65  can be suppressed. The recording device  10  can be stably installed by the four leg portions  11 . 
     The base frame  67  has a box shape of the substantially quadrangular prism shape, and the height direction of the quadrangular prism is along the X-axis. The base frame  67  is held between the pair of side frames  62  and  63  on the upper side than the middle of the pair of side frames  62  and  63  in the Z direction. The base frame  67  holds a part of the main components of the recording device  10 . 
     The recording medium holding unit  20  described above is disposed between the pair of side frames  62  and  63  in the X direction and between the base frame  67  and the lower frame  65  in the Z direction. 
     The main frame  61  is supported on upper end portions of the pair of side frames  62  and  63 . The main frame  61  extends in the +X direction from the side frame  62 , and extends in the −X direction from the side frame  63 . In the X direction, the length of the main frame  61  is substantially equal to the length of the lower frame  65 . The main frame  61  is fixed to the pair of side frames  62  and  63  in the X direction along with the lower frame  65 , and thus the rigidity of the frame  60  is further improved. 
     The sub-frame  69  and the sub-base frame  68  are disposed in the −X direction that is one of the X direction. The sub-frame  69  and the sub-base frame  68  are not limited to be disposed in the −X direction, and may be disposed on both sides or one side in one −X direction and the other +X direction in the X direction. 
     The sub-frame  69  includes a lower end fixed to the surface on the upper side of the lower frame  65 , and is upright in the Z direction. The side frame  63  and the sub-frame  69  are disposed to face each other in the X direction with the sub-base frame  68  interposed therebetween. The sub-frame  69  includes an upper end for supporting the main frame  61 . 
     The sub-base frame  68  includes three wall surfaces  68   a ,  68   c , and  68   d  extending in the X direction. The wall surface  68   a  is along the XY plane, and the wall surfaces  68   c  and  68   d  are along the XZ plane. The ink cartridge  35  described above is accommodated on the upper side of the sub-base frame  68 . Accordingly, the rigidity of the frame  60  is improved, and a space inside the frame  60  can be effectively utilized. Note that an ink tank or the like having a larger capacity than the ink cartridge  35  may be accommodated between the sub-base frame  68  and the lower frame  65 . 
     When viewed from the Y direction, the base frame  67  and the sub-base frame  68  are located at different positions in the Z direction. Thus, the rigidity of the frame  60  is further improved. 
     The side frames  62  and  63 , the lower frame  65 , the base frame  67 , the sub-base frame  68 , and the sub-frame  69  are formed of a flat plate made of iron, aluminum, alloy, or the like, and are shaped through machining such as drilling, bending, and the like. Means such as fitting, fastening by screws, rivets, or the like, joining, and the like are employed singly or in combination for assembling the frame  60 . The frame  60  may further include additional structural members in addition to each of the frames described above. 
     As illustrated in  FIG.  4   , the base frame  67  includes a top wall surface  67   a , a lower wall surface  67   b , a front wall surface  67   c , and a rear wall surface  67   d  as four wall surfaces extending in the X direction. In the following description, the four wall surfaces may be also collectively referred to as four wall surfaces  67   w.    
     Each of the four wall surfaces  67   w  has a substantially rectangular shape elongated in the X direction. The upper wall surface  67   a  and the lower wall surface  67   b  are along the XY plane to face each other in the Z direction. The front wall surface  67   c  and the rear wall surface  67   d  are along the XZ plane to face each other in the Y direction. 
     At the upper wall surface  67   a , an end portion in the +X direction is referred to as an end portion  67   a   1 , and an end portion in the −X direction is referred to as an end portion  67   a   2 . At the lower wall surface  67   b , an end portion in the +X direction is referred to as an end portion  67   b   1 , and an end portion in the −X direction is referred to as an end portion  67   b   2 . At the front wall surface  67   c , an end portion in the +X direction is referred to as an end portion  67   c   1 , and an end portion in the −X direction is referred to as an end portion  67   c   2 . At the rear wall surface  67   d , an end portion in the +X direction is referred to as an end portion  67   d   1 , and an end portion in the −X direction is referred to as an end portion  67   d   2 . 
     A through hole  67   h   1  is disposed on the upper wall surface  67   a  closer to the end portion  67   a   2  than a center in the X direction. A through hole  67   h   2  is disposed on the front wall surface  67   c  closer to the end portion  67   c   2  than the center in the X direction. Through holes  67   h   1  and  67   h   2  correspond to the duct  73  illustrated in dashed lines. The duct  73  protrudes on the upper side from the through hole  67   h   1  and is coupled to the negative pressure chamber  31   r  described above. The duct  73  is coupled to the negative pressure chamber  75  described above via the through hole  67   h   2 . 
     As illustrated in  FIG.  5   , in the four wall surfaces  67   w  of the base frame  67 , three end portions  67   a   2 ,  67   c   2 , and  67   d   2  are fixed from the +X direction to the side frame  63  that is one of the pair of side frames  62  and  63  in the −X direction that is one of the X direction. Note that all of four end portions  67   a   2 ,  67   b   2 ,  67   c   2 , and  67   d   2  of the four wall surfaces  67   w  may be fixed to the side frame  63 , but at least two of the four end portions  67   a   2 ,  67   b   2 ,  67   c   2 , and  67   d   2  may be fixed. 
     Although not illustrated, in the same manner as described above, in the four wall surfaces  67   w , three end portions  67   a   1 ,  67   c   1 , and  67   d   1  are fixed from the −X direction to the side frame  62  that is the other of the pair of side frames  62  and  63  in the +X direction that is the other of the X direction. Note that all of the four end portions  67   a   1 ,  67   b   1 ,  67   c   1 , and  67   d   1  of the four wall surfaces  67   w  may be fixed to the side frame  62 , but at least two of the four end portions  67   a   1 ,  67   b   1 ,  67   c   1 , and  67   d   1  may be fixed. 
     As described above, at least two of the four wall surfaces  67   w  are sandwiched between the pair of side frames  62  and  63  to be fixed. This allows the rigidity of the frame  60  to be further improved. 
     Each of the intermediate roller  42  and the transport roller  43   
     includes an end portion of a shaft in the −X direction rotatably held by the side frame  63 . Although not illustrated, each of the intermediate roller  42  and the transport roller  43  includes an end portion of the shaft in the +X direction rotatably held by the side frame  62 . 
     The main frame  61  is disposed on the upper rear side of the base frame  67  when viewed from the X direction. This ensures a movable range (not illustrated) of the recording unit  30  that is supported by the main frame  61  and moves in the X direction. 
     When viewed from the Z direction, the recording medium holding unit  20  is located on the front wall surface  67   c  side of the base frame  67  in the Y direction. When viewed from the Z direction, at least a part of the recording medium holding unit  20  is disposed overlapping the base frame  67  in the Y direction. Accordingly, the length in the front-rear direction is shortened, and the recording device  10  can be miniaturized. 
     As illustrated in  FIG.  6   , the duct  73 , which is a functional component related to the recording of the recording unit  30 , is disposed inside the four wall surfaces  67   w  of the base frame  67 . Thus, the inside of the base frame  67  is effectively utilized, and the recording device  10  can be miniaturized. Note that the above-described functional components disposed inside the four wall surfaces  67   w  are not limited to the duct  73 . Here, the above-described functional components include all components attached to the base frame  67 , and examples thereof include, for example, the negative pressure chamber  31   a , the negative pressure mechanism  75 , and the maintenance tank  83 . 
     The negative pressure chamber  31   r  is held on the upper side of the upper wall surface  67   a  among the four wall surfaces  67   w  of the base frame  67 . Thus, a plurality of openings (not illustrated) for the communication between the negative pressure chamber  31   r  and the support face  31   s  are disposed outside the base frame  67 . As a result, the base frame  67  need not be provided with holes corresponding to the plurality of openings, and the rigidity of the base frame  67  is improved. Since the negative pressure chamber  31   r  is located outside the base frame  67 , a maintenance property of the negative pressure chamber  31   r  can be improved. 
     A part of or the entirety of the negative pressure chamber  31   r  may be disposed inside the base frame  67 . That is, for example, the negative pressure chamber  31   r  may be held on the lower side of the upper wall surface  67   a . Thus, the inside of the base frame  67  is effectively utilized, and the recording device  10  can be miniaturized. 
     The negative pressure mechanism  75  is held in the +Y direction of the front wall surface  67   c  among the four wall surfaces  67   w  of the base frame  67 . Thus, air can flow from the negative pressure mechanism  75  to the front side of the recording device  10  via the front wall surface  67   c.    
     A part of or the entirety of the negative pressure mechanism  75  may be disposed inside the base frame  67 . That is, for example, the negative pressure mechanism  75  may be held in the −Y direction of the front wall surface  67   c . Thus, the inside of the base frame  67  is effectively utilized, and the recording device  10  can be miniaturized. 
     The maintenance tank  83  is disposed between the upper wall surface  67   a  of the base frame  67  and the negative pressure chamber  31   r.    
     The lower face side path forming member  41   a  is held on the lower wall surface  67   b  among the four wall surfaces  67   w  of the base frame  67 . The rear face side path forming member  45  is held on the rear wall surface  67   d  among the four wall surfaces  67   w  of the base frame  67 . The upper face side path forming member  47  is held on the upper wall surface  67   a  among the four wall surfaces  67   w  of the base frame  67 . 
     As described above, each member is held on the four wall surfaces  67   w  of the base frame  67 , and the four wall surfaces  67   w  are effectively utilized. 
     As illustrated in  FIG.  7   , the support portion  31  has an elongated shape in the X direction. The upper side of the duct  73  communicates with the negative pressure chamber  31   r . Note that in  FIG.  7   , a state is illustrated in which the duct  73  is cut at a plane equally dividing the duct  73  in the X direction along the YZ plane. 
     The negative pressure chamber  31   r  is a space having a small room shape elongated in the X direction. The supporting surface  31   s  is disposed on the upper side of the negative pressure chamber  31   r . Other than a region in the negative pressure chamber  31   r  in communication with the duct  73  and a plurality of openings described below of the support face  31   s  are blocked. 
     A gutter portion  85  is coupled to the support face  31   s  in the +Y direction. A surface on the upper side of the gutter portion  85  is inclined to the lower side in the +Y direction. As a result, the gutter portion  85  guides the above-described ink ejected to be discarded to the support face  31   s  to the above-described maintenance tank  83 . 
     As illustrated in  FIG.  8   , a plurality of openings  31   h  communicating with the negative pressure chamber  31   r  are disposed on the support face  31   s . When a negative pressure is applied to the negative pressure chamber  31   r , air is suctioned from the plurality of openings  31   h  to the negative pressure chamber  31   r . Thus, the recording medium  22  (not illustrated) is adsorbed to the support face  31   s.    
     In the support face  31   s , a groove portion  31   a  is provided next to a region where the plurality of openings  31   h  are disposed. The groove portion  31   a  includes a plurality of grooves extending in the Y direction. In the groove portion  31   a , the ink ejected to the support face  31   s  is guided to the gutter portion  85  in the +Y direction. 
     As illustrated in  FIG.  9   , a plurality of shaft supporting members  91  and a pair of support portion supporting members  93  are disposed in the base frame  67 . 
     Two shaft supporting members  91  are disposed inside both ends of each of the shafts of the intermediate roller  42  and the transport roller  43  in the X direction on the upper wall surface  67   a  of the base frame  67 . The shaft supporting members  91  are located on the lower side of the intermediate roller  42  and the transport roller  43  and rotatably support the shafts. Since the two shaft supporting members  91  support the above-described shaft at two points, occurrence of deflection in the intermediate roller  42  and the transport roller  43  is suppressed, and a transport property of the recording medium  22  is improved. The number of the shaft supporting members  91  is not limited to two, and may be three or more. 
     Each of the pair of support portion supporting members  93  is disposed on the upper side that is in the Z direction of the negative pressure chamber  31   r  (not illustrated) to correspond to the two shaft supporting members  91 . As illustrated in  FIG.  10   , each of the support portion supporting members  93  is supported on the upper wall surface  67   a  of the base frame  67  and extends in the Y direction, and supports the shaft supporting member  91  near an end in the −Y direction. The support portion  31  (not illustrated) is located on the upper side of the pair of support portion supporting members  93 , and supported at the lower side by the pair of support portion supporting members  93 . That is, the pair of support portion supporting members  93  supports the support portion  31  and the two shaft supporting members  91 . 
     Returning to  FIG.  9   , three upper face side path forming members  47  are disposed side by side in the X direction. The three upper face side path forming members  47  are held on the upper wall surface  67   a  of the base frame  67  at positions other than positions where the shaft supporting members  91  and the support portion supporting members  93  are disposed in the X direction. Accordingly, interference between the upper face side path formation members  47  and the shaft supporting member  91  and the support portion supporting members  93  can be prevented. 
     As described above, each member is held on the upper wall surface  67   a  of the base frame  67 , and the upper wall surface  67   a  is effectively utilized. 
     According to the present embodiments, the following advantages can be obtained. 
     In the recording device  10 , the mechanical strength is improved, and the installation space can be reduced. Specifically, the frame  60  is formed by assembling the lower frame  65 , the pair of side frames  62  and  63 , and the base frame  67 . The base frame  67  includes the four wall surfaces  67   w , thus having excellent rigidity. The pair of side frames  62  and  63  support the base frame  67  therebetween. The lower frame  65  supports a lower end of each of the pair of side frames  62  and  63 . As a result, the frame  60  having a small size and excellent rigidity is formed. 
     The frame  60  is assembled and the main components are held in the frame  60 . Thus, the irregularities of the external shape can be reduced, and thus the design properties of the appearance of the recording device  10  can be improved. From the above, the recording device  10  having the excellent design properties and the mechanical strength and reduced installation space can be provided.
