As shown in FIG. 7, when the medium 16 is cut, the control unit 34 moves the carriage 18 located at the home position HP in the third direction D3.

As shown in FIG. 8, when the carriage 18 moves in the third direction D3, the tube 15 passes vertically above the cutter 19. In the vertical direction, the tube support member 41 is located between the cutter 19 and the tube 15. When the carriage 18 moves to the standby position SP, the carriage engaging portion 56 and the cutter engaging portion 57 are connected.

Specifically, as shown in FIGS. 5 and 6, the engaging claw 60 is pushed vertically downward by the guide piece 68 moving in the third direction D3, and is pushed in the first direction D1 by the receiving wall 71. Is done. The engaging claw 60 rotates to allow the carriage engaging portion 56 to move. The control unit 34 stops the movement of the carriage 18 at a position where the receiving rib 66 has passed the engaging claw 60. As a result, the engaging claw 60 gets over the receiving rib 66. At this time, the protruding piece 63 is inserted into the holder 65.

Subsequently, the control unit 34 moves the carriage 18 located at the standby position SP in the second direction D2. When the carriage 18 moves in the second direction D2, the engaging claw 60 is located at the first position P1 shown by the alternate long and short dash line in FIG. The first position P1 is a position where the engaging claw 60 comes into contact with the receiving surface 69. The carriage 18 moves the cutter 19 in the second direction D2 by pushing the engaging claw 60 whose receiving surface 69 is located at the first position P1. The cutter 19 cuts the medium 16 by moving in the second direction D2.

As shown in FIG. 9, the control unit 34 temporarily stops the carriage 18 and the cutter 19 at the cutting end position EP, and then moves the carriage 18 and the cutter 19 in the third direction D3.
As shown in FIGS. 5 and 6, the engaging claw 60 located at the first position P1 is pushed in the first direction D1 by the guide rib 67 moving in the third direction D3. The engaging claw 60 rotates in the first direction D1 to allow the guide rib 67 to move. The engaging claw 60 that rides on the guide rib 67 is guided by the guide surface 70 and is located at the second position P2 shown by the alternate long and short dash line in FIG. In the carriage 18, the holder 65 pushes the protruding piece 63 in the third direction D3 with the engaging claw 60 positioned at the second position P2. Therefore, the cutter 19 moves in the third direction D3 together with the carriage 18 and returns to the standby position SP.

As shown in FIG. 8, when the carriage 18 and the cutter 19 move to the standby position SP, the control unit 34 moves the carriage 18 again in the second direction D2.
As shown in FIGS. 5 and 6, the engaging claw 60 located at the second position P2 is guided in the first direction D1 by the guide piece 68, and passes through the third position P3 shown by the alternate long and short dash line in FIG. To avoid the receiving rib 66. The carriage engaging portion 56 and the cutter engaging portion 57 are disconnected. The cutter 19 stays at the standby position SP, the carriage 18 moves in the second direction D2, and returns to the home position HP.

The effect of this embodiment will be described.
(1) The tube 15 connected to the second ink storage unit 14 passes vertically above the first wall 47 with which the cutter 19 engages in the carriage 18. That is, the rigidity of the tube 15 makes it easy for the tube 15 to pass vertically above the cutter 19, and even when the cutter 19 is engaged with the carriage 18, the possibility that the tube 15 interferes with the cutter 19 can be reduced.

(2) In the second wall 48 on the second direction D2 side of the carriage 18, the first outer wall surface 51 located at a position away from the first wall 47 is located near the first wall 47. It is located outside 52. That is, since the second outer wall surface 52 is located inside the first outer wall surface 51, the possibility that the tube 15 passing vertically above the first wall 47 is sandwiched between, for example, the second wall 48 and the exterior member is reduced. it can.

(3) The first upper end 47a of the first wall 47 is located at a position lower than the second upper end 48a of the second wall 48 and the third upper end 49a of the third wall 49. Therefore, it is possible to reduce the possibility that the tube 15 passing vertically above the first wall 47 rides on the second wall 48 or the third wall 49.

(4) If the tube 15 hits the carriage 18 or the tube 15 and the carriage 18 rub against each other, the carriage 18 may vibrate. At that point, the tube 15 is fixed to the carriage 18. Therefore, the relationship between the tube 15 and the carriage 18 can be stabilized, and the vibration of the carriage 18 can be reduced.

(5) Since the carriage 18 has a tube support member 41 that supports the tube 15, the behavior of the tube 15 can be stabilized. If the vibration of the tube 15 is transmitted to the storage portion support member 40 via the tube support member 41, the positions of the storage portion support member 40 and the discharge head 17 may be displaced. In particular, when the position of the ejection head 17 is moved to other than the second direction D2 and the third direction D3, the ejection control in the ejection head 17 cannot correct the position, which may affect the print quality. The vibration of the tube 15 tends to cause a deviation in the second direction D2 or the third direction D3, but the tube support member 41 is at the same position as the discharge head 17 in the first direction D1 and the second direction D2. Is fixed to. Therefore, the displacement of the discharge head 17 in a direction other than the second direction D2 and the third direction D3 can be reduced due to the vibration of the tube 15.

(6) Since the cushioning material 45 is provided between the tube support member 41 and the storage portion support member 40, the vibration transmitted to the storage portion support member 40 can be reduced.
This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

The tube support member 41 may be detachably provided with respect to the storage portion support member 40. That is, the tube support member 41 does not have to be fixed to the storage portion support member 40 by the screw 43. For example, the tube support member 41 may be mounted so as to be fitted in a recess formed in the storage portion support member 40. When the tube support member 41 is detachably provided with respect to the storage portion support member 40, for example, when the medium 16 is clogged, the user can remove the tube support member 41 from the storage portion support member 40 to remove the medium 16 from the storage portion support member 40. Since the work space for taking out the medium 16 can be expanded, the medium 16 can be easily taken out.

The contact position where the tube support member 41 mounted on the storage portion support member 40 comes into contact with the storage portion support member 40 is located at the same position as the discharge head 17 in the first direction D1 and the second direction D2. May be good. As a result, the displacement of the discharge head 17 can be reduced.

The carriage 18 may not be provided with the tube support member 41, and the tube 15 may be fixed to the storage portion support member 40.
The tube support member 41 and the storage portion support member 40 may be integrally formed.

-The tube 15 does not have to be fixed to the carriage 18.
The first upper end 47a of the first wall 47 may be at the same height as the second upper end 48a of the second wall 48, or may be located vertically above the second upper end 48a. The first upper end 47a of the first wall 47 may be at the same height as the third upper end 49a of the third wall 49, or may be located vertically above the third upper end 49a. The heights of the second upper end 48a of the second wall 48 and the third upper end 49a of the third wall 49 may be different.

-The carriage 18 may have at least one of the second wall 48 and the third wall 49 flat. That is, the second wall 48 may be a member in which the first outer wall surface 51 and the second outer wall surface 52 are located at the same position in the second direction D2. The third wall 49 may be a member in which the third outer wall surface 53 and the fourth outer wall surface 54 are located at the same position in the third direction D3.

-Ribs may be formed on at least one of the first wall 47, the second wall 48, and the third wall 49. When the ribs are formed, the strength is increased, and the possibility that the member on which the ribs are formed is deformed can be reduced. The ribs may be formed, for example, so that a plurality of linear ribs are arranged in parallel with each other, or may be formed in a grid pattern. When forming the ribs, the first outer wall surface 51, the second outer wall surface 52, the third outer wall surface 53, and the fourth outer wall surface 54 form the vertices of a plurality of ribs protruding in a direction away from the second ink storage portion 14. It is a virtual surface including. That is, the first outer wall surface 51, the second outer wall surface 52, the third outer wall surface 53, and the fourth outer wall surface 54 are virtual surfaces in a state where the gaps between the ribs are filled.

The cutter 19 may cut the medium 16 when moving in the third direction D3.
The technical idea and its action and effect grasped from the above-described embodiments and modifications are described below.

(A) The printer has a first ink storage unit that stores ink, a second ink storage unit that stores the ink supplied from the first ink storage unit, the first ink storage unit, and the second ink. A tube for connecting the storage unit, a discharge head for ejecting the ink toward the medium, a carriage for mounting the discharge head and the second ink storage unit, and a cutter for cutting the medium are provided. The carriage has a first wall located in the first direction from the second ink storage portion and a carriage engaging portion provided on the first wall, and the ejection head and the second ink storage portion are second. The cutter is moved in two directions and a third direction opposite to the second direction, and the cutter is in the second direction or the third direction in a state where the cutter engaging portion of the cutter is engaged with the carriage engaging portion. The medium is cut by moving in the direction, and the tube passes vertically above the first wall.

According to this configuration, the tube connected to the second ink reservoir passes vertically above the first wall on which the cutter engages in the carriage. That is, the rigidity of the tube makes it easy for the tube to pass vertically above the cutter, and even when the cutter is engaged with the carriage, the possibility that the tube interferes with the cutter can be reduced.

(B) In the printer, the carriage has a second wall located in the second direction from the second ink storage portion, and the second wall is the first outer wall surface and the first outer wall surface. It has a second outer wall surface located in the first direction, and the first outer wall surface may be located in the second direction from the second outer wall surface.

According to this configuration, in the second wall on the second direction side of the carriage, the first outer wall surface located at a position away from the first wall is outside the second outer wall surface located near the first wall. To position. That is, since the second outer wall surface is located inside the first outer wall surface, it is possible to reduce the possibility that the tube passing vertically above the first wall surface is sandwiched between the second wall surface and the exterior member, for example.

(C) In the printer, the carriage has a second wall located in the second direction from the second ink storage unit and a third wall located in the third direction from the second ink storage unit. However, the first upper end vertically above the first wall may be located lower than the second upper end vertically above the second wall and the third upper end vertically above the third wall.

According to this configuration, the first upper end of the first wall is located lower than the second upper end of the second wall and the third upper end of the third wall. Therefore, it is possible to reduce the possibility that the tube passing vertically above the first wall runs on the second wall or the third wall.

(D) In the printer, the tube may have a connecting portion connected to the second ink storage portion and a fixed portion fixed to the carriage.
The carriage may vibrate if the tube hits the carriage or if the tube and carriage rub against each other. In that respect, according to this configuration, the tube is fixed to the carriage. Therefore, the relationship between the tube and the carriage can be stabilized and the vibration of the carriage can be reduced.

(E) In the printer, the carriage has a storage portion support member that supports the second ink storage portion and a tube support member that supports the tube, and the tube support member is the storage portion support member. It may be removable.

According to this configuration, since the carriage has a tube support member that supports the tube, the behavior of the tube can be stabilized. Since the tube support member is removable from the storage portion support member, for example, when the medium is clogged, the tube support member can be removed from the storage portion support member to expand the work space and facilitate the removal of the medium. ..

(F) In the printer, the contact position where the tube support member mounted on the storage portion support member contacts the storage portion support member is the same position as the discharge head in the first direction and the second direction. It may be located in.

If the vibration of the tube is transmitted to the storage portion support member via the tube support member, the positions of the storage portion support member and the discharge head may be displaced. In particular, when the position of the ejection head is moved in a direction other than the second direction and the third direction, the ejection control in the ejection head cannot correct the correction, which may affect the print quality. The vibration of the tube tends to cause a deviation in the second or third direction, but according to this configuration, the tube support member contacts the reservoir support member at the same position as the discharge head in the first and second directions. To do. Therefore, the displacement of the discharge head in directions other than the second direction and the third direction can be reduced due to the vibration of the tube.

(G) In the printer, the carriage has a storage portion support member that supports the second ink storage portion and a tube support member that supports the tube, and the storage portion support member and the tube support member. The fixed position where the ink is fixed may be located at the same position as the discharge head in the first direction and the second direction.

According to this configuration, the tube support member is fixed to the storage portion support member at the same position as the discharge head in the first direction and the second direction.
