Title: Feed Tray and Image Recording Apparatus

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is based upon and claims the benefit of priority from prior Japanese patent application No. 2021-012207 filed on Jan. 28, 2021, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present disclosure relates to a feed tray capable of accommodating a roll body, and an image recording apparatus having the feed tray. 
     BACKGROUND 
     An image recording apparatus including a feed tray capable of accommodating a roll body having a configuration where a sheet-shaped medium such as a paper, a cloth and a label is rolled in a roll shape is known. For example, JP-A-H09-263348 discloses a roll sheet feeding apparatus (image recording apparatus) having a sheet feeding tray (feed tray) configured to accommodate a roll sheet (roll body), a housing configured to detachably hold the sheet feeding tray, and a drive roller (feed roller) for feeding the roll sheet accommodated in the sheet feeding tray to an image forming unit (recording unit). 
     In the configuration of JP-A-H09-263348, a roll medium, which is a sheet-shaped medium unrolled from the roll body accommodated in the feed tray, is fed by the feed tray. In general, insertion of the feed tray into the housing is performed in a state where the roll medium is unwound from the roll body by a predetermined length. Since the length of the roll medium to be unrolled can be arbitrarily determined by an operator, the unrolled roll medium may become excessively long. In this case, when inserting the feed tray into the housing, a tip end of the unrolled roll medium may come into contact with a member inside the housing, which may cause a jam. 
     SUMMARY 
     An object of the present disclosure is to provide a feed tray and an image recording apparatus capable of suppressing a roll medium unrolled from a roll body from coming into contact with a member inside a housing when the feed tray is inserted into the housing. 
     An aspect of the present disclosure is a feed tray including: a first accommodation part in which a roll body having a configuration where a first sheet-shaped medium is rolled in a roll shape is accommodated; 
     a conveyance guide configured to define a conveyance path for a roll medium which is the first sheet-shaped medium unrolled from the roll body accommodated in the first accommodation part; and 
     a shutter movable between an intercept position where the shutter is located in the conveyance path and a retreat position where the shutter is further from the conveyance path than the intercept position. 
     Another aspect of the present disclosure is an image recording apparatus including: 
     a housing; 
     the above feed tray configured to be capable of being inserted into and pulled out from the housing; 
     a feed roller configured to feed the roll medium from the feed tray by applying a feeding force to the roll medium; and 
     a recording unit configured to record an image on the roll medium fed by the feed roller. 
     According to the feed tray and the image recording apparatus of the present disclosure, by setting the shutter to the intercept position, it is possible to suppress the roll medium unrolled from the roll body and guided to the conveyance path from becoming excessively long. This makes it possible to suppress the roll medium unrolled from the roll body from coming into contact with a member inside the housing when inserting the feed tray into the housing of the image recording apparatus. In addition, by setting the shutter to the retreat position, it is possible to convey the roll medium along the conveyance path.

     DETAILED DESCRIPTION 
     First Embodiment 
     Hereinafter, a printer  100  (the image recording apparatus of the present disclosure) according to a first embodiment of the present disclosure will be described with reference to  FIG. 1 . Note that, the upper and lower direction, the front and rear direction and the right and left direction shown in  FIG. 1  are referred to as the upper and lower direction, the front and rear direction and the right and left direction of the printer  100 . 
     (Overall Configuration of Printer  100 ) 
     As shown in  FIG. 1 , the printer  100  includes a housing  100   a , a feed tray  11 , a feed roller  2 , a separating piece  41 , a pair of conveying rollers  3   a , a pair of sheet discharging rollers  3   b , a cutter mechanism  4 , a head  5  (the recording unit of the present disclosure), a sheet discharging tray  6 , an intermediate roller pair  9 , and a control unit  10 . The sheet discharging tray  6  is configured to be capable of being inserted into pulled out from the housing  100   a  in the front and rear direction via an opening  102  formed in a front wall of the housing  100   a.    
     The feed tray  11  is configured to be capable of being inserted into and pulled out from a lower part of the housing  100   a . The feed tray  11  has a first accommodation part  11   a  capable of accommodating a roll body R having a configuration where a long-length sheet P 1  (the first sheet-shaped medium of the present disclosure) is rolled in a roll shape and a second accommodation part  11   b  capable of accommodating a cut sheet P 2  (the second sheet-shaped medium of the present disclosure), which is a sheet shorter than the long-length sheet P 1 , in a state of being multiply stacked in the upper and lower direction. The cut sheet P 2  is a sheet cut to a fixed size, and in the present embodiment, is a rectangular A4-sized sheet having short and long sides. The cut sheet P 2  is accommodated in the second accommodation part  11   b  so that the short sides follow a conveyance direction, which will be described later. Width directions of the roll sheet P 1   a  (the roll medium of the present disclosure) unrolled from the roll body R in the feed tray  11  and the cut sheet P 2  coincide with the right and left direction. The detailed configuration of the feed tray  11  will be described later. 
     The feed roller  2  is configured to deliver the roll sheet P 1   a  unrolled from the roll body R accommodated in the first accommodation part  11   a  or the cut sheet P 2  accommodated in the second accommodation part  11   b  from the feed tray  11 . In descriptions below, the roll sheet P 1   a  and the cut sheet P 2  are referred to as ‘sheet P’ when they are not distinguished. The feed roller  2  is pivotally supported by a tip end of an arm  2   a , and is configured to rotate by drive of a feeding motor (not shown). The arm  2   a  is rotatably supported by a support shaft  2   b . The arm  2   a  is urged by an urging member (not shown) so that the feed roller  2  comes close to a bottom surface of the feed tray  11 . When the feeding motor is driven by control of the control unit  10 , the feed roller  2  rotates to apply a conveyance force in a direction from the front toward the rear to the sheet P in contact with the feed roller  2 . Thereby, the sheet P is delivered from the feed tray  11 . Note that, the arm  2   a  is configured to be able to retreat upward when attaching and detaching the feed tray  11  to and from the housing  100   a.    
     The separating piece  41  is to prevent double feeding when delivering the cut sheet P 2  from the feed tray  11 . The separating piece  41  is located on a downstream side of the feed tray  11  in a conveyance direction of the sheet P by the feed roller  2  (a direction from the front toward the rear; in descriptions below, simply referred to as ‘conveyance direction’). The separating piece  41  is inclined so that an end portion on a rear side is located further upward than an end portion on a front side. A surface of the separating piece  41  is formed with a fine unevenness pattern. The separating piece  41  is configured to come into contact with a central portion of the cut sheet P 2  in the width direction, thereby separating the cut sheet P 2  in contact with the feed roller  2  and the other cut sheet P 2 . The sheet P delivered from the feed tray  11  and coming into contact with the separating piece  41  is guided obliquely upward. 
     The pair of conveying rollers  3   a  are configured by a drive roller configured to rotate by drive of a conveyance motor (not shown) and a driven roller configured to rotate according to the drive roller. The pair of sheet discharging rollers  3   b  is configured by a drive roller configured to rotate by drive of a sheet discharging motor (not shown) and a driven roller configured to rotate according to the drive roller. When the conveyance motor and the sheet discharging motor, which are not shown, are driven by control of the control unit  10 , the pair of conveying rollers  3   a  and the pair of sheet discharging rollers  3   b  rotate to convey the sheet P while sandwiching the sheet P. The pair of conveying rollers  3   a  are located behind the head  5 , and the pair of sheet discharging rollers  3   b  are located in front of the head  5 . The pair of conveying rollers  3   a  are configured to convey the sheet P forward while sandwiching the sheet P. The pair of sheet discharging rollers  3   b  are configured to convey the sheet P forward while sandwiching the sheet P that is conveyed forward by the pair of conveying rollers  3   a.    
     The cutter mechanism  4  is located on a further downstream side than the separating piece  41  with respect to the conveyance direction. The cutter mechanism  4  includes, for example, a cutter  4   a  consisting of a disc-shaped rotating blade and a driven blade, and a cutting motor (not shown) configured to reciprocally drive the rotating blade of the cutter  4   a  in the right and left direction. The roll sheet P 1   a  unrolled from the roll body R and conveyed along a conveyance path is cut in the width direction of the roll sheet P 1   a  by the rotating blade of the cutter  4   a  as the cutting motor is driven by control of the control unit  10 . 
     The intermediate roller pair  9  is provided on a further downstream side than the cutter mechanism  4  with respect to the conveyance direction and on a further upstream side than the pair of conveying rollers  3   a  with respect to the conveyance direction. The intermediate roller pair  9  is configured by a drive roller configured to rotate by drive of an intermediate motor (not shown) and a driven roller configured to rotate according to the drive roller. When the intermediate motor (not shown) is driven by control of the control unit  10 , the intermediate roller pair  9  rotates to convey the sheet P while sandwiching the sheet P. The intermediate roller pair  9  is located above a conveyance guide  21  of the feed tray  11 , which will be described later. The intermediate roller pair is configured to convey the sheet P upward while sandwiching the sheet P that is delivered from the feed tray  11  by the feed roller  2  and is then guided obliquely upward by the conveyance guide  21 . 
     The head  5  includes a plurality of nozzles (nozzle) formed on a lower surface and a driver IC (not shown). When the driver IC is driven by control of the control unit  10 , ink is ejected from the nozzles, so that an image is recorded on the sheet P at the time when the sheet P conveyed by the feed roller  2 , the intermediate roller pair  9  and the pair of conveying rollers  3   a  passes through an image recording position facing the lower surface of the head  5 . Note that, the head  5  may be either a line-type configured to eject the ink from the nozzles in a state where a position is fixed or a serial-type configured to eject the ink from the nozzles while moving in the right and left direction. The sheet P on which an image is formed by the head  5  is accommodated on the sheet discharging tray  6 . 
     The control unit  10  is connected to the feeding motor, the intermediate motor, the conveyance motor, the sheet discharging motor, the cutting motor and the driver IC via an internal bus (not shown). The control unit  10  has a CPU (Central Processing Unit), a ROM (Read Only Memory) and a RAM (Random Access Memory). In the ROM, programs and data for the CPU to perform various controls are stored. The RAM is configured to temporarily store data that is used when the CPU runs programs. 
     (Configuration of Feed Tray  11 ) 
     Subsequently, a configuration of the feed tray  11  is described with reference to Fits.  2  to  9 . In descriptions below, directions of respective parts of the feed tray  11  are described based on a posture of the feed tray  11  in a state of being mounted to the housing  100   a . The feed tray  11  has a substantially quadrilateral shape, as seen from above. The feed tray  11  has a bottom wall  31  and sidewalk  32  to  35  provided on edges of the bottom wall  31  and is formed to have a box shape opening upward. 
     The bottom wall  31  extends in a plane orthogonal to the upper and lower direction, as shown in  FIGS. 3 and 5 . An upper surface of the bottom wall  31  is configured as a bottom surface  31   a  of the feed tray  11 . The sidewalk  32  and  33  extend upward from both left and right end edges of the bottom wall  31 . In addition, the sidewalls  32  and  33  extend in the front and rear direction from a front end portion to a rear end portion of the bottom wall  31 . The sidewall  34  extends upward from a front end edge of the bottom wall  31 . In addition, the sidewall  34  extends along the right and left direction from a right end portion to a left end portion of the bottom wall  31 . 
     The sidewall  35  is provided by four on a rear end edge of the bottom wall  31 . In  FIGS. 2 and 4 , only the two sidewalls on an inner side are shown. The sidewall  35  has a guide surface  35   a  connected to a rear end portion of the bottom surface  31   a  and inclined so that an upper end portion is located further rearward than a lower end portion. The four sidewalls  15  are spaced from each other in the right and left direction. When the feed tray  11  is mounted to the housing  100   a , the separating piece  41  is located between the two sidewalk  35  on the inner side among the four sidewalls  35  aligned in the right and left direction. When an attachment part  20 , which will be described later, is detached from the feed tray  11 , the guide surfaces  35   a  of the sidewalls  35  guide obliquely upward the cut sheet P 2 , which is being conveyed rearward by the feed roller  2 , together with the separating piece  41 . 
     As described above, the feed tray  11  is provided therein with the first accommodation part  11   a  capable of accommodating the roll body R and the second accommodation part  11   b  capable of accommodating the cut sheet P 2  in a state of being multiply stacked in the upper and lower direction. The first accommodation part  11   a  and the second accommodation part  11   b  are aligned along the conveyance direction. The second accommodation part  11   b  is located on a further downstream side than the first accommodation part  11   a  with respect to the conveyance direction. 
     The first accommodation part  11   a  is configured to accommodate the roll body R in a posture where an axis direction of the roll body coincides with the right and left direction. As shown in  FIG. 3 , the first accommodation part  11   a  has a cylindrical core member Rc, a support base  13  and two rollers  14  and  15  configured to support the roll body R, and a roll cover  16 . The roll body R has a configuration where the long-length sheet P 1  is rolled in a roll shape on an outer peripheral surface of the cylindrical core member Rc. The roll body R is arranged so that an axis direction (a direction perpendicular to the drawing sheet of  FIG. 1 ) along a rotation axis Rx (a central axis of the core member Rc) is parallel to the right and left direction. 
     The support base  13  extends along the right and left direction. The rollers  14  and  15  all extend in the right and left direction, and are arranged separated from each other in the front and rear direction. The rollers  14  and  15  are all supported on an upper end portion of the support base  13  so as to be rotatable about rotation axes extending in the right and left direction The rollers  14  and  15  are configured to support the roll body R from below in a state of being in contact with an outer peripheral surface of a lower part of the roll body R. 
     A gap G is formed between a lower surface of the support base  13  and the bottom surface  31   a  of the feed tray  11 . When setting the roll sheet P 1   a  in the feed tray  11 , the roll body R supported on the support base  13  is rotated in a counterclockwise direction in  FIG. 3 , and the roll sheet P 1   a  is unrolled from a front-side part of the roll body R. Then, the roll sheet P 1   a  unrolled from the roll body R passes through the gap G and is pulled out from the front side of the support base  13  to the rear side of the support base  13 . 
     The roll cover  16  is a member configured to cover the roll body R accommodated in the first accommodation part  11   a . The roll cover  16  extends along the right and left direction and is formed longer than widths of the support base  13  and the rollers  14  and  15 . The roll cover  16  is also arranged to be able to be close to the outer peripheral surface of the roll body R of a maximum size that can be accommodated in the first accommodation part  11   a . As a result, even if the roll body R is loosened and therefore the outer diameter of the roll body R is to increase, the outer peripheral surface of the roll body R comes into contact with an inner surface of the roll cover  16 , so that it is possible to restrict an increase in outer diameter. Note that, the roll cover  16  may be detachably mounted to the feed tray  11 , and may be configured to be rotatable about a rotary shaft extending along the right and left direction at a lower end thereof. In a case where the roll cover  16  can rotate about the rotary shaft at the lower end thereof, the roll cover  16  can rotate rearward about the rotary shaft, thereby exposing an accommodation space for the roll body R above the support base  13 . 
     The second accommodation part  11   b  is configured to accommodate the cut sheet P 2  in a posture where the width direction of the cut sheet coincides with the right and left direction. In the present embodiment, the second accommodation part  11   b  is a rear-side part and an upper-side part of the bottom surface  31   a  of the feed tray  11  with respect to the first accommodation part  11   a . The rear-side part of the bottom surface  31   a  with respect to the first accommodation part  11   a  is configured to support a plurality of cut sheets P 2  placed in a state of being stacked, from below. Note that, in the present embodiment, when accommodating the cut sheet P 2  in the second accommodation part  11   b , an attachment part  20 , which will be described later, is detached from the feed tray  11 , as shown in  FIG. 7 . In addition, when performing recording of an image while delivering, from the feed tray  11 , the roll sheet P 1   a  unrolled from the roll body R accommodated in the first accommodation part  11   a , the cut sheet P 2  is removed from the second accommodation part  11   b.    
     The feed tray  11  further has an attachment part  20 . The attachment part  20  is attached to a front side of the sidewalk  35  and is configured to be detachably mounted to the feed tray  11 . The attachment part  20  includes a conveyance guide  21  and a shutter  22 . Note that, in  FIG. 1 , the shutter  22  is not shown. 
     The conveyance guide  21  is configured to define a part of the conveyance path for the roll sheet P 1   a  unrolled from the roll body R accommodated in the first accommodation part  11   a . As shown in  FIGS. 3 and 5 , the conveyance guide  21  has a lower guide  21   a  configured to support the unrolled roll sheet P 1   a  from below, and an upper guide  21   b  configured to support the unrolled roll sheet P 1   a  from above. The conveyance path for the roll sheet P 1   a  is formed between the lower guide  21   a  and the upper guide  21   h.    
     The lower guide  21   a  and the upper guide  21   b  extend in the right and left direction. The lower guide  21   a  and the upper guide  21   h  are formed along curves, when seen in the right and left direction. In a state where the feed tray  11  is mounted to the housing  100   a , the lower guide  21   a  and the upper guide  21   b  are arranged by one on each of both sides of the feed roller  2  in the right and left direction. 
     The two lower guides  21   a  are each provided on a front side of the guide surfaces  35   a  of the two sidewalls  35  on the right side and on a front side of the guide surfaces  35   a  of the two sidewalls  35  on the left side among the four sidewalls  35 . The lower guide  21   a  is provided along the bottom surface  31   a  and the guide surface  35   a , from an upper side of a rear end part of the bottom wall  31  to a front side of an upper end part of the sidewall  35 . The lower guide  21   a  is formed so that it is located upward from the front toward the rear. 
     The two upper guides  21   b  are provided on an opposite side to the two lower guides  21   a  with the roll sheet P 1   a  unrolled from the roll body R being interposed therebetween. The upper guide  21   b  is formed so that a front end portion is above a central portion and a rear end portion is above the front end portion and the central portion, when seen in the right and left direction. In addition, as shown in  FIGS. 2 and 4 , a central part of the upper guide  21   h  is formed with an opening  21   b   2  in a direction of intersecting with an extension direction of the upper guide  21   b . In the opening  21   b   2 , a tip end portion  22   b  of the shutter  22 , which will be described later, can be inserted. 
     The lower guide  21   a  and the upper guide  21   b  are arranged spaced in a direction orthogonal to the right and left direction. An interval between the lower guide  21   a  and the upper guide  21   b  in the direction orthogonal to the right and left direction becomes narrower from the front toward the rear. 
     In the present embodiment that, the conveyance path for the roll sheet P 1   a  is defined by the feed roller  2 , the conveyance guide  2 , the intermediate roller pair  9 , the pair of conveying rollers  3   a , and the pair of sheet discharging rollers  3   b . Note that, as described above, when accommodating the cut sheet P 2  in the second accommodation part  11   b , the attachment part  20  is detached from the feed tray  11 . Therefore, in the present embodiment, the conveyance path for the cut sheet P 2  is defined by the feed roller  2 , the guide surface  35   a  of the sidewall  35 , the separating piece  2 , the intermediate roller pair  9 , the pair of conveying rollers  3   a , and the pair of sheet discharging rollers  3   b.    
     The shutter  22  is arranged by one on each of both sides of the feed roller  2  in the right and left direction. The two shutters  22  each include an arm part  22   a  formed in front of the upper guide  21   b  and a tip end portion  22   b  provided at a tip end of the arm part  22   a . The arm part  22   a  is formed along the upper part of the upper guide  21   b . A rear end of the arm part  22   a  is rotatable supported on an upper end part of the upper guide  21   b  by a rotary shaft  24  whose axis direction is the right and left direction. As shown in  FIGS. 2 and 4 , a left end of the arm part  22   a  on a left side is formed with a convex portion  25  extending leftward in the right and left direction, and a right end of the arm part  22   a  on a right side is formed with a convex portion  25  extending rightward in the right and left direction. 
     The tip end portion  22   b  extends from the tip end of the arm part  22   a  in a direction of intersecting with the conveyance path defined by the conveyance guide  21 . A part of the tip end portion  22   h  passes through the opening  21   b   2  formed at the upper guide  21   b  and is located in the conveyance path defined by the conveyance guide  21 . 
     The shutter  22  is configured to be rotated about the rotary shaft  24  to be movable between an intercept position (refer to  FIGS. 2 and 3 ) where the shutter  122  is located in the conveyance path defined by the conveyance guide  21  and a retreat position (refer to  FIGS. 4 and 5 ) where the shutter  122  is further from the conveyance path than the intercept position. In the present embodiment, the tip end portion  22   b  of the shutter  22  being in the retreat position is located on a further front and upper side than the tip end portion  22   b  of the shutter  22  being in the intercept position. As shown in  FIG. 3 , when the shutter  22  is in the intercept position, the tip end portion  22   b  penetrates through the conveyance path defined by the conveyance guide  21 , In addition, when the shutter  22  is in the intercept position, the shutter  22  is located on a further downstream side than a position directly under the feed roller  2 , which is a feed position of the roll sheet P 1   a  by the feed roller  2 , with respect to the conveyance direction. As shown in  FIG. 5 , when the shutter  22  is in the retreat position, a tip end of the tip end portion  22   b  retreats out of the conveyance path. When the shutter  22  is in the retreat position, the roll sheet Na that is conveyed by the feed roller  2  passes through the conveyance path defined by the conveyance guide  21  and is guided to the cutter mechanism  4 . 
     In addition, the shutter  22  is configured to be movable to the intercept position in conjunction with pullout of the feed tray  11  from the housing  100   a , and to the retreat position in conjunction with insertion of the feed tray  11  into the housing  100   a . In the below, the configuration is described in detail with reference to  FIGS. 8 and 9 . 
     As described above, the arm part  22   a  of shutter  22  is formed with the convex portion  25 . In addition, the housing  100   a  has a protruding portion  51  formed in a position corresponding to the convex portion  25  in the upper and lower direction and in the right and left direction and extending in the front and rear direction. A front end portion of the protruding portion  51  has an inclined surface  51   a  that is included located upward from the front toward the rear. 
     When the feed tray  11  is inserted into the housing  100   a , the convex portion  25  moves from front to the rear along the inclined surface  51   a , and the convex portion  25  gets on the protruding portion  51 . This causes the shutter  22  to rotate about the rotary shaft  24  and to move to the retreat position, in conjunction with insertion of the feed tray  11  into the housing  100   a . In addition, when the feed tray  11  is pulled out from the housing  100   a , the convex portion  25  moves from the rear to the front along the inclined surface  51   a , and the convex portion  25  gets down the protruding portion  51 . This causes the shutter  22  to rotate about the rotary shaft  24  and to move to the intercept position, in conjunction with pullout of the feed tray  11  from the housing  100   a.    
     As described above, the feed tray  11  of the first embodiment has the first accommodation part  11   a  capable of accommodating the roll body R, the conveyance guide  21  configured to define the conveyance path for the roll sheet P 1   a  unrolled from the roll body R, and the shutter  22  configured to be movable between the intercept position where the shutter  22  is located in the conveyance path and the retreat position where the shutter  22  is further from the conveyance path than the intercept position. In addition, the printer  100  of the first embodiment has the housing  100   a , the above-described feed tray  11 , the feed roller  2 , and the head  5 . According to this, by setting the shutter  22  to the intercept position, it is possible to suppress the roll sheet P 1   a  unrolled from the roll body R and guided to the conveyance path from becoming excessively long. This makes it possible to suppress the roll sheet P 1   a  unrolled from the roll body R from coming into contact with a member inside the housing  100   a  when inserting the feed tray  11  into the housing  100   a  of the printer  100 . In addition, by setting the shutter  22  to the retreat position, it is possible to convey the roll sheet P 1   a  along the conveyance path. 
     Further, in the feed tray  11  of the first embodiment, the shutter  22  being in the intercept position is configured to penetrate through the conveyance path defined by the conveyance guide  21 . This makes it possible to prevent the roll sheet P 1   a  unrolled from the roll body R and guided to the conveyance path from going to a further downstream side than the shutter  22  with respect to the conveyance direction along the conveyance path. 
     Further, in the feed tray  11  of the first embodiment, the tip end of the tip end portion  22   h  of the shutter  22  being in the retreat position is configured to retreat out of the conveyance path. This makes it possible to prevent the roll sheet P 1   a  unrolled from the roll body R and guided to the conveyance path from coming into contact with the shutter  22  when conveying the roll sheet P 1   a.    
     Further, in the feed tray  11  of the first embodiment, the shutter  22  is configured to be movable to the intercept position, in conjunction with pullout of the feed tray  11  from the housing  100   a . This makes it possible to take less labor and to avoid forgetting to move the shutter  22  to the intercept position, as compared to a configuration where the shutter  22  is manually moved to the intercept position when pulling out the feed tray  11  from the housing  100   a . Therefore, it is possible to more securely suppress the roll sheet P 1   a  guided to the conveyance path from becoming excessively long, and to more securely suppress the roll sheet P 1   a  unrolled from the roll body R from coming into contact with a member inside the housing  100   a  when pulling out the feed tray  11  from the housing  100   a  and then again inserting the feed tray  11  into the housing  100   a.    
     Further, in the feed tray  11  of the first embodiment, the shutter  22  is configured to be movable to the retreat position, in conjunction with insertion of the feed tray  11  into the housing  100   a . Further, in the feed tray  11  of the first embodiment, the shutter  22  is rotatably supported on the conveyance guide  21  by the rotary shaft  24 , and is configured to be rotated about the rotary shaft  24  to be movable between the intercept position and the retreat position. 
     More specifically, in the printer  100  of the first embodiment, the feed tray  1 I is configured to be capable of being inserted into pulled out from the housing  100   a  along insertion/pullout direction (front and rear direction) orthogonal to the axis direction (right and left direction) of the roll body R accommodated in the first accommodation part  11   a . In addition, both ends of the shutter  22  in the right and left direction are formed with the convex portions  25  extending in the right and left direction, and the housing  100   a  has the inclined surfaces  51   a  provided in the positions corresponding to the convex portions  25  in the right and left direction and inclined upward toward a direction (from the front toward the rear) in which the feed tray  11  is inserted into the housing  100   a . The shutter  22  is rotatably supported on the conveyance guide  21  so that the rotary shaft  24  is directed in the right and left direction, and is configured to rotate about the rotary shaft  24  to be able to thus move to the retreat position as the convex portion  25  moves along the inclined surface  51   a  in conjunction with insertion of the feed tray  11  into the housing  100   a.    
     This makes it possible to take less labor and to avoid forgetting to move the shutter  22  to the intercept position, as compared to a configuration where the shutter  22  is manually moved to the intercept position before inserting the feed tray  11  into the housing  100   a . This makes it possible to suppress a jam due to contact of the roll sheet P 1   a  and the shutter  22  during the conveyance operation of the printer  100 . In addition, since the shutter  22  rotates and moves, the shutter  22  can easily move between the intercept position and the retreat position. 
     In addition, the feed tray  11  of the first embodiment further has the second accommodation part  11   b  capable of accommodating the cut sheet P 2  in a state of being multiply stacked, and the conveyance guide  21  can be attached and detached to and from the feed tray  11  while supporting the shutters  22 . When conveying the cut sheet P 2  accommodated in the second accommodation part  11   b , the conveyance guide  21  and the shutters  22  supported on the conveyance guide  21  are no longer required. In particular, when the number of stacked cut sheets P 2  accommodated in the second accommodation part  11   b  is large, the conveyance guide  21  and the shutters  22  may hinder the conveyance of the cut sheet P 2 . Therefore, in the first embodiment, the conveyance guide  21  is configured to be attachable and detachable to and from the feed tray  11 . This makes it possible to securely convey the cut sheet even when the number of stacked cut sheets P 2  is large in the feed tray  11  configured to accommodate both the roll body R and the cut sheet P 2 , and to suppress the roll sheet P 1   a  unrolled from the roll body R from coming into contact with a member inside the housing  100   a  when inserting the feed tray  11  into the housing  100   a.    
     Further, in the printer  100  of the first embodiment, the shutter  22  is arranged by one on each of both sides of the feed roller  2  in the axis direction (right and left direction) of the roll body R accommodated in the first accommodation part  11   a . In a case where the shutter  22  is arranged only on one side of the feed roller  2  with respect to the right and left direction, the roll sheet P 1   a  unrolled from the roll body R and guided to the conveyance path is suppressed from becoming excessively long only by the shutter  22  arranged on one side of the feed roller  2 . Then, the unrolled roll sheet P 1   a  may be obliquely tilted with respect to the conveyance direction. In this case, the conveyance of the roll sheet P 1   a  by the feed roller  2  after moving the shutter  22  to the retreat position is not appropriately performed. The first embodiment can solve the above problems. 
     Further, in the printer  100  of the first embodiment, when the shutter  22  is in the intercept position, the shutter  22  is located on a further downstream side than the feed position of the roll sheet P 1   a  by the feed roller  2  with respect to the conveyance direction. This makes it possible to securely unroll the roll sheet P 1  to the feed position by the feed roller  2 . 
     Subsequently, a configuration of a feed tray  111  according to a second embodiment is described with reference to  FIGS. 10 to 13 . In descriptions below, the configurations that are similar to the first embodiment are denoted with the same reference signs, and the descriptions thereof are omitted. A printer of the second embodiment has a similar configuration to the printer  100  of the first embodiment, except including the feed tray  111  instead of the feed tray  11  and including a configuration of a protruding portion  151 , which will be described later, instead of the protruding portion  51 . 
     The feed tray  111  includes a first accommodation part  111   a  capable of accommodating the roll body R, and a conveyance guide  121  configured to define the conveyance path for the roll sheet P 1   a  unrolled from the roll body R. The conveyance guide  121  includes a first member  121   a  and a second member  121   b  extending in the insertion/pullout direction of the feed tray  111  with respect to the housing  100   a , i.e., in the front and rear direction. 
     The first member  121   a  is configured to support the roll sheet P 1   a  unrolled from the roll body R accommodated in the first accommodation part  111   a , from below. The second member  121   b  is located above the first member  121   a . As shown in  FIG. 11 , a rear end part of the second member  121   b , which is a central part in the right and left direction, is formed with a notch  121   b   2 . The conveyance path for the roll sheet P 1   a  is formed between the first member  121   a  and the second member  121   b . The roll sheet P 1   a  unrolled from the roll body R passes through the conveyance path, is sent to a downstream side with respect to the conveyance direction and comes into contact with the feed roller  2  from the part of the second member  121   b , at which the notch  121   b   2  is formed, so that the roll sheet is fed to a further downstream side with respect to the conveyance direction. 
     In addition, in the second embodiment, the cut sheet P 2  in a state of being multiply stacked can be placed on an upper surface of the second member  121   b , This allows the feed tray  111  to accommodate the plurality of cut sheets P 2 . 
     The feed tray  111  further includes a shutter  122  configured to be movable between an intercept position where the shutter  122  is located in the conveyance path defined by the conveyance guide  121  and a retreat position where the shutter  122  is further from the conveyance path than the intercept position. The shutter  122  includes a first part  122   a  and a second part  122   b . The shutter  122  is rotatably supported on the first member  121   a  so that a rotary shaft Rs is directed in the right and left direction. The shutter  122  is urged by an urging member (not shown) so as to be in the intercept position shown in  FIG. 12 . Specifically, an elastic force for rotating the shutter  122  in a counterclockwise direction in  FIG. 12  is applied from the urging member to the shutter  122 . The urging member is, for example, a spring. 
     As shown in  FIG. 11 , the shutter  122  is arranged by one on each of both sides of the notch  121   b   2  in the right and left direction. In other words, the shutter  122  is arranged by one on each of both sides of the feed roller  2  in the right and left direction. When the shutter  122  is in the intercept position, the shutter  122  is arranged on a further downstream side than the feed position of the roll sheet P 1   a  by the feed roller  2  with respect to the conveyance direction (refer to  FIGS. 12 and 13 ). 
     As shown in  FIG. 10 , the first part  122   a  is located above the second part  122   b  and on an opposite side to the second part  122   b  with respect to the rotary shaft Rs. The shutter  22  is configured to rotate about the rotary shaft Rs by the elastic force applied by the urging member, and to be in the intercept position as a result of the first part  122   a  coming into contact with the second part  122   b . That is, in the second embodiment, when the shutter  122  is in the intercept position, the first part  122   a  is in linear contact with a lower surface of the second part  121   b  of the conveyance guide  121 . In other words, when the shutter  122  is in the intercept position, the first part  122   a  penetrates through the conveyance path defined by the conveyance guide  121 . 
     In the present embodiment, the shutter  122  is configured to be movable to the retreat position in conjunction with insertion of the feed tray  111  into the housing  100   a . The housing  100   a  of the printer of the second embodiment has a protruding portion  151  formed in a position corresponding to the second part  122   b  of the shutter  122  in the upper and lower direction and in the right and left direction and extending in the front and rear direction. 
     When the feed tray  111  is inserted into the housing  100   a , the second part  122   b  is pushed by the protruding portion  151 , so that the shutter  122  rotates in a clockwise direction about the rotary shaft Rs against the elastic force of the urging member and the first part  122   a  retreats from the conveyance path in conjunction with movement of the second part  122   b . This causes the shutter  122  to rotate about the rotary shaft Rs and to move to the retreat position, in conjunction with insertion of the feed tray  111  into the housing  100   a . Note that, as shown in  FIG. 13 , when the shutter  122  is in the retreat position, the first part  122   a  of the shutter  122  retreats out of the conveyance path. Note that, in the second embodiment, when the shutter  122  is in the retreat position, the roll sheet P 1   a  fed by the feed roller  2  passes through the conveyance path defined by the conveyance guide  121 , is sent to the guide surface  35   a  of the sidewall  35 , and is guided to the cutter mechanism  4  by the guide surface  35   a.    
     In addition, in the present embodiment, the shutter  122  is configured to be movable to the intercept position in conjunction with pullout of the feed tray  111  from the housing  100   a . As described above, when seen from the right and left direction, the shutter  122  is urged by the urging member (not shown) so as to be a position (a position in  FIG. 12 ), i.e., the intercept position where the first part  122   a  is in contact with the second member  121   b . When the feed tray  111  is pulled out from the housing  100   a , the push-up of the second part  122   b  by the protruding portion  151  is released, so that the shutter  122  rotates about the rotary shaft Rs and the first part  122   a  returns to the position where the first part is in contact with the second member  12   l  b. This causes the shutter  122  to rotate about the rotary shaft  24  and to move to the intercept position, in conjunction with pullout of the feed tray  111  from the housing  100   a.    
     As described above, in the feed tray  111  of the second embodiment, the conveyance guide  121  includes the first member  121   a  and the second member  121   b  extending in the insertion/pullout direction (front and rear direction) of the feed tray  111  with respect to the housing  100   a , and the conveyance path for the roll sheet P 1   a  is formed between the first member  121   a  and the second member  121   b . In addition, the shutter  122  is rotatably supported on the first member  121   a  so that the axis direction (right and left direction) of the roll body R accommodated in the first accommodation part  111   a  is the direction of the rotary shaft Rs. The shutter  122  is configured to be rotated about the rotary shaft Rs to be movable between the intercept position and the retreat position, and is in the intercept position as the first part  122   a  of the shutter  122  comes into contact with the second member  121   b . According to this, since the shutter  22  rotates, the shutter can easily move between the intercept position and the retreat position. In addition, the shutter  122  can be set to the intercept position by using the second member  121   b  of the conveyance guide  121 . 
     Further, in the feed tray  111  of the second embodiment, the second member  121   b  is located above the first member  121   a , and the cut sheet P 2  can be accommodated in a state of being multiply stacked on the upper surface of the second member  121   b . This makes it possible to suppress the roll sheet P 1   a  unrolled from the roll body R from coming into contact with a member inside the housing  100   a  when inserting the feed tray  111  into the housing  100   a , in the feed tray  111  configured to accommodate both the roll body R and the cut sheet P 2 . 
     Further, in the printer of the second embodiment, the housing  100   a  is formed with the protruding portion  151  extending in the insertion/pullout direction (front and rear direction) of the feed tray  111  with respect to the housing  100   a . The second part  122   b  is pushed by the protruding portion  151  in conjunction with the insertion of the feed tray  111  into the housing  100   a , so that the shutter  122  can rotate about the rotary shaft Rs to move to the retreat position. This makes it possible to take less labor and to avoid forgetting to move the shutter  122  to the intercept position, as compared to a configuration where the shutter  122  is manually moved to the intercept position before inserting the feed tray  111  into the housing  100   a . This makes it possible to suppress a jam due to contact of the roll sheet P 1   a  and the shutter  122  during the conveyance operation of Printer name. 
     Modified Embodiments 
     Although the preferred embodiments of the present disclosure have been described, the present invention is not limited to the above-described embodiments, and can be variously changed within the claims. 
     In the above-described embodiments, the feed tray enables to accommodate the roll body R and the cut sheet P 2 . However, the feed tray of the present disclosure may also be configured to be able to accommodate only the roll body. 
     In the above-described embodiments, the shutter is arranged by one on each of both sides of the feed roller  2  in the right and left direction. However, the shutter may also be arranged by two or more on each of both sides of the feed roller  2  in the right and left direction or may also be arranged only on one side of the feed roller, and the numbers of shutters to be arranged on both sides may be different. However, preferably, the shutter is arranged by at least one on each of both sides of the feed roller  2  in the right and left direction. 
     In the feed tray  11  of the first embodiment, the lower guide  21   a  and the upper guide  21   b  may be arranged by two or more on each of both sides of the feed roller  2  or may be arranged by one on each of both sides of the feed roller  2  in the right and left direction in a state where the feed tray  11  is mounted to the housing  100   a.    
     In the above-described embodiments, the shutter is rotatably supported on the conveyance guide but may also be rotatably supported directly on the feed tray. In addition, the shutter may be configured to be movable between the intercept position and the retreat position, and is not limited to the configuration of rotating about the rotary shaft. 
     In the above-described embodiments, when the shutter is in the intercept position, the roll sheet P 1   a  unrolled from the roll body R is in contact with the shutter. However, when the shutter is in the intercept position, the shutter may not completely intercept the conveyance path. In this case, the shutter being in the intercept position may not be in contact with the roll sheet P 1   a  unrolled from the roll body R. 
     In the above-described embodiments, the shutter is configured to be movable to the intercept position in conjunction with pullout of the feed tray from the housing. However, the shutter may also be configured to be manually movable to the intercept position. In addition, in the above-described embodiments, the shutter is configured to be movable to the retreat position in conjunction with insertion of the feed tray into the housing. However, the shutter may also be configured to be manually movable to the retreat position. 
     In the above-described embodiments, when the shutter is in the retreat position, the tip end of the shutter retreats out of the conveyance path defined by the conveyance guide. However, when the shutter is in the retreat position, the tip end of the shutter may remain in the conveyance path defined by the conveyance guide. Note that, in this case, the feed tray is configured so that, even when the tip end of the shutter being in the retreat position remains in the conveyance path, the roll sheet P 1   a  unrolled from the roll body R can pass through the conveyance path defined by the conveyance guide. 
     In the above-described embodiments, the shutter being in the intercept position is configured to penetrate through the conveyance path. However, the shutter being in the intercept position may also be configured not to penetrate through the conveyance path. For example, the shutter being in the intercept position may be configured to be in contact with an inner surface of the conveyance guide defining the conveyance path. 
     In the first embodiment, the conveyance guide  21  has the lower guide  21   a  and the upper guide  21   b  but may not have the lower guide  21   a  in this case, the conveyance path for the roll sheet P 1   a  is formed between the upper guide  21   b  and the guide surface  35   a  of the sidewall  35 . In other words, the conveyance guide includes the upper guide  21   b  and the guide surface  35   a.    
     Further, in the first embodiment, the shutter  22  is rotatably supported on the upper guide  21   b . However, the shutter  22  may not be supported on the upper guide  21   b . For example, the upper guide  21   b  and the shutter  22  may also be integrally configured. For example, the upper guide may be formed with a shutter part (corresponding the shutter of the present disclosure) extending into the conveyance path. In this case, the upper guide is configured to be rotatable about the right and left direction that is a rotation axis, and the shutter part is configured to move between the intercept position and the retreat position in conjunction with rotation of the upper guide. 
     The image recording apparatus of the present disclosure can also be applied to a complex machine, a copier and the like, in addition to the printer. In addition, the printer may be applied to not only the inkjet printer but also a laser-type printer configured to form an electrostatic latent image by exposing a photosensitive member by laser or an LED-type electrophotographic printer configured to form an electrostatic latent image by exposing a photosensitive member by an LED. In addition, the sheet-shaped medium is not limited to the sheet and may also be a cloth, a label or the like as long as it is a sheet type.
