In addition, it is preferable that a cover 45 is attached to the front of the supply mechanism 42, and when the cover 45 is removed, the supply mechanism 42 is exposed so that maintenance can be performed.

  As shown in FIG. 6, the longitudinal direction of the container 30 mounted on the container mounting portion 27 is the front-back direction (the left-right direction in FIG. 6) crossing the width direction. On the other hand, the moving area of the carriage 33 and the exhaust mechanism 50 are positioned inside the casing 12 such that the longitudinal direction is the width direction (the left-right direction in FIG. 2 and the direction perpendicular to the plane of FIG. 6). Are located in The container 30 is located in the housing 12 at a position different from the moving area of the carriage 33 and the exhaust mechanism 50 in the vertical direction, and at a position vertically below the moving area of the carriage 33 and the exhaust mechanism 50. Will be accommodated. Therefore, even if the ink stored in the container 30 may leak out, the influence on the carriage 33 and the exhaust mechanism 50 located above the container mounting portion 27 is small.

  In the container mounting portion 27 of the present embodiment, three containers 30 can be mounted. That is, a total of six housing bodies 30 are housed in the housing unit 12 in such a manner that three housing bodies 30 are distributed to both ends of the housing unit 12 in the width direction.

  The number of the containers 30 mounted on the container mounting portion 27 can be arbitrarily changed. For example, the number of the containers 30 that can be mounted on the container mounting portion 27 may be more than six or less than six. Further, the container mounting portion 27 is provided only at one end in the width direction of the housing portion 12, and the plurality of containers 30 are combined into one container mounting portion 27 without being distributed to both ends of the housing portion 12. You may make it accommodate. However, providing the container mounting portions 27 at both ends in the width direction of the housing portion 12 and distributing and storing a plurality of the containers 30 in these two container mounting portions 27 reduces the space in the recording device 11. This is preferable because it can be used efficiently and has a good weight balance.

  Further, different types of recording materials (for example, ink) may be stored (filled) in the plurality of containers 30, or the same type of recording material may be stored in the plurality of containers 30. When a plurality of containers 30 containing the same type of recording material are mounted on the container mounting portion 27, the remaining amount of one container 30 supplying the recording material has decreased or disappeared. At this time, it is also possible to switch the container 30 that supplies the recording material to another container 30 that contains the same type of recording material, and to continue supplying the recording material. Accordingly, when a plurality of containers 30 each containing a recording material of the same type are mounted on the recording apparatus 11, when the recording apparatus 11 performs the recording operation, the recording operation is not interrupted. It is possible to replace the unused container 30.

  Furthermore, a state in which the number of the containers 30 smaller than the maximum number of the containers 30 that can be mounted on the container mounting portion 27 is mounted on the container mounting portion 27, that is, the container mounting portion 27 is empty. However, the recording apparatus 11 may be configured to be usable even in a certain state. In this case, it is possible to leave the container mounting portion 27 open so that the type of recording material to be used can be increased or decreased as needed.

  In addition, a storage element such as an IC chip is mounted on the container 30, and terminals capable of contacting the storage element are disposed on the container mounting portion 27, based on the amount of recording material used in the recording device 11. The calculated remaining amount of the recording material may be stored in the storage element. When a storage element is mounted on the container 30, information such as the type and amount of the recording material stored in the container 30 may be stored in the storage element. With this configuration, the recording device 11 can determine whether or not an appropriate container 30 has been stored in the container mounting section 27 based on the information stored in the storage element.

  A suction mechanism 36 capable of sucking ink from the liquid ejecting head 32 is disposed at an end of the movement area of the carriage 33 in the width direction (the direction orthogonal to the paper surface in FIG. 6). The suction mechanism 36 is connected to a waste liquid tube 37 that introduces the ink sucked from the liquid jet head 32 into the recovery body 29 as a waste liquid. Then, for example, when the suction mechanism 36 sucks ink from the liquid ejecting head 32 before the start of printing or after the end of printing, the sucked ink (waste liquid) is introduced into the recovery body 29 through the waste liquid tube 37.

  A partition wall 46 is arranged in the housing 12 so as to extend in the front-rear direction and the width direction. The recording unit 31 is disposed above the partition wall 46 in the housing 12.

Further, the housing container 19 is provided with a recess 19a on the front side constituting a part of the front wall portion 12f when attached to the housing portion 12. Then, when removing the cut pieces stored in the storage container 19, the storage container 19 is detached from the housing portion 12 by, for example, putting a hand on the grip 19 a.

  It is preferable that the housing 12 accommodates a medium holding unit 16 that holds a roll body R in which the medium S is rolled up in a cylindrical shape so that the medium holding unit 16 can be pulled out through the front opening 13. Then, by removing the storage container 19 from the housing 12, the medium holding unit 16 can be pulled out of the housing 12 through the front opening 13.

  The medium holding unit 16 includes a front plate unit (plate unit) 17 that forms a part of the front wall unit 12 f when housed in the housing unit 12, and a roll body that is mounted to support the roll body R. It is preferable to include a pair of support walls 18 disposed at positions sandwiching R, and an insertion opening forming portion 44 that forms an insertion opening 43 of the medium S between the front plate 17 and the support wall 18. In addition, the front plate 17 of the medium holding unit 16 is supported by the supporting unit 23 that supports the storage container 19 attached to the housing unit 12, and a hand is hung when the medium holding unit 16 is pulled out from the housing unit 12. It is preferable to provide a handle portion 24 and a notification portion 25 that can perform the operation. The notification unit 25 can be, for example, a notification light.

  When the storage container 19 is attached to the housing 12, the legs 19 b of the storage container 19 are placed on the support 23 that is recessed above the front plate 17. On the other hand, when the storage container 19 is removed from the housing section 12, the insertion port 43, the support section 23, the handle section 24, and the notification section 25 are exposed.

  As shown in FIG. 8, the medium holding unit 16 includes feed path forming members 66, 67, 68, and 69 that form a feed path for feeding the medium S toward the recording unit 31, and a feed path. And a plurality of feed roller pairs 60, 61, 62 for feeding the medium S along the line. The feed roller pair 60 includes a drive roller 60a and a driven roller 60b, and the feed roller pair 61 includes a drive roller 61a and a driven roller 61b.

  The feed roller pairs 60, 61, and 62 are supported by a pair of support walls 18 arranged side by side in the width direction of the medium holding unit 16, and are arranged inside the support walls 18. The feed path forming member 66 is fixed below the drive rollers 60a and 61a, and the feed path forming member 67 is fixed downstream of the feed path forming member 66 in the feeding direction of the medium S.

  The feeding path forming member 66 holds a medium detecting unit 65 that detects an end of the medium S. The medium detection unit 65 is arranged downstream of the feeding roller pair 60 arranged closest to the insertion port 43 in the feeding path in the feeding direction.

  The medium detection unit 65 is an optical sensor including a light emitting unit having a light emitting diode or the like and a light receiving unit having a photodiode or the like, for example. Then, the medium detection unit 65 detects the leading end of the medium S from the change in the light receiving state caused by the passage of the medium S.

  When the medium detection unit 65 detects the leading end of the medium S inserted from the insertion opening 43, for example, the notification light serving as the notification unit 25 changes from the unlit state to the lit state, and the medium S is supplied by the feeding roller pair 60. Notify that it was placed in a position where it can be sent. Thus, by performing the work of inserting the medium S while watching the notification unit 25, it is possible to easily confirm that the medium S has been properly inserted to a position where it can be automatically transported.

  After the medium detection unit 65 detects the leading end of the medium S inserted from the insertion port 43 and the container detection unit 47 detects that the storage container 19 is mounted on the housing unit 12, the feeding roller pair 60 , 61, and 62 may feed the medium S to a position where recording can be started.

  That is, the housing container 19 cannot be attached to the front opening 13 unless the medium holding unit 16 is housed in the housing unit 12, and the feeding roller pairs 60, 61, and 62 connect the medium holding unit 16 to the housing unit 12. If not, the feeding of the medium S cannot be started. Therefore, when the container detection unit 47 detects that the storage container 19 is mounted on the housing unit 12, it is determined that the medium holding unit 16 is stored in the housing unit 12, and the feeding of the medium S is started. It becomes possible.

  The cleaner 71 may be detachably attached to the feeding path forming member 66 on the downstream side of the medium detection unit 65 in the feeding direction.
