Detailed Description
Hereinafter, embodiments of the liquid ejecting apparatus will be described with reference to the drawings. The liquid ejecting apparatus is, for example, an ink jet printer that performs recording (printing) by ejecting ink, which is one example of a liquid, onto a medium such as paper.
As shown in fig. 1, the liquid ejecting apparatus 11 includes a housing 12, and the housing 12 has predetermined lengths as a height, a depth, and a width in a state of being installed in a use place. The enclosure 12 includes a bottom wall 13, a front wall 14, a rear wall 15, and side walls 16 and 17 extending in the depth direction and the gravity direction.
In the present embodiment, the width direction and the depth direction are substantially horizontal, and the direction of gravity is represented by the Z axis when the housing 12 is placed on a horizontal plane. The direction (front) from the depth side (rear side) in the depth direction to the front side (front side) is represented by the Y axis. The width direction is represented by an X axis intersecting both the Z axis and the Y axis. The X, Z, and Y axes are coordinate axes representing the width, height, and depth, respectively.
The housing 18 is disposed on one end side in the width direction of the enclosure 12 (the side wall 16 side on the right end side in fig. 1) so as to protrude forward. In the present embodiment, one end side in the width direction is referred to as a primary side, and the other end side (side wall 17 side) is referred to as a counter-primary side. The storage section 18 stores a plurality of liquid storage bodies 20 capable of storing liquid in a width direction. The front side of the liquid container 20 is higher than the rear side in a stepwise manner. The liquid container 20 may be provided with an inlet 20a into which the liquid can be injected. When the injection port 20a is provided in a portion of the liquid container 20 protruding forward from the front wall 14, the injection operation is easy.
The housing 12 accommodates: the liquid ejecting apparatus includes a liquid ejecting head 23, a carriage 24 that holds the liquid ejecting head 23, a guide shaft 25 that guides movement of the carriage 24, a supply flow path 26 that connects the carriage 24 and the liquid storage body 20, a maintenance device 30, and a mounting portion 40. The liquid ejecting head 23 includes a plurality of nozzles 22 and an opening surface 23a on which the nozzles 22 are opened, and the liquid ejecting head 23 is configured to eject liquid from the nozzles 22 to the medium S conveyed forward.
A conveyance path 27 for the medium S is formed in the housing 12 near the center in the width direction. A support table 28 capable of supporting the medium S is disposed in a region of the transport path 27 where the liquid ejecting head 23 ejects the liquid. The front wall 14 is provided with a discharge port 14a for discharging the printed medium S to the outside of the housing 12.
The maintenance device 30 is disposed on the initial side of the support base 28. The housing portion 18 is disposed in front of the maintenance device 30, and the mounting portion 40 is disposed in rear of the maintenance device 30. That is, the housing portion 18, the maintenance device 30, and the attachment portion 40 are arranged in order from the front side in the depth direction toward the depth.
The maintenance device 30 includes: a cap 31, a discharge flow path 32 having an upstream end connected to the cap 31, a suction mechanism 33 disposed in the middle of the discharge flow path 32, a wiping member 34 capable of wiping the opening surface 23a, a slider 36 holding the cap 31, and a support member 36. The suction mechanism 33 is configured to be capable of performing a suction operation for sucking the inside of the cover 31. The slider 35 is provided so as to be movable relative to a support member 36 disposed therebelow. The support member 36 supports the wiper member 34 and the suction mechanism 33, and supports the cover 31 via the slider 35, thereby unitizing the components of the maintenance device 30.
The slider 35 has an engagement projection 35a projecting upward at an end on the initial side in the width direction. When the carriage 24 moving toward the initial side is engaged with the engagement projection 35a, the slider 35 moves obliquely upward with the movement of the carriage 24, the cap 31 is brought into contact with the liquid ejecting head 23, and a closed space in which the nozzles 22 are opened is formed. In this way, the action of the cover 31 to form a closed space is referred to as "capping". The positions of the cap 31 and the slider 35 when capping are shown by two-dot chain lines in fig. 1. When the suction mechanism 33 is driven during capping, the interior of the liquid ejecting head 23 is sucked through the nozzle 22. In this way, the operation of performing suction through the nozzles 22 and discharging the liquid in the liquid ejecting head 23 is referred to as "suction cleaning".
The waste liquid container 50 is detachably attached to the attachment portion 40. The waste liquid container 50 is a container capable of containing waste liquid discharged by the suction operation. An insertion opening 15a for inserting the waste liquid container 50 into the housing 12 is opened in the rear wall 15. As shown by the two-dot chain line in fig. 1, the waste liquid container 50 is inserted into the housing 12 while moving from the rear to the front, and is mounted on the mounting portion 40.
The mounting portion 40 has: a discharge portion 41 connected to the downstream end of the discharge flow path 32, a wall 42 provided with a guide portion 42a, and a device-side terminal 43. The waste liquid container 50 includes an introduction portion 51 into which waste liquid can be introduced, and an IC chip 54 having a terminal portion 53. When the waste liquid container 50 is mounted on the mounting portion 40, the discharge portion 41 is inserted into the introduction portion 51, and the terminal portion 53 is connected to the device-side terminal 43.
A portion of the discharge flow path 32 that overlaps the discharge portion 41 is referred to as a connection portion 32c, a portion between the suction mechanism 33 and the connection portion 32c is referred to as a downstream flow path 32b, and a portion between the suction mechanism 33 and the cover 31 is referred to as an upstream flow path 32 a. Of the discharge flow path 32, at least the downstream flow path 32b and the upstream flow path 32a are formed of flexible tubes capable of flexural displacement.
The cap 31 has a suction portion 31a connected to an upstream end of the upstream flow passage 32 a. The lid 31 may be disposed so that the suction portion 31a faces the outside (initial side) of the housing 12. In this case, the discharge portion 41, the suction mechanism 33, and the cover 31 are arranged in a depth direction different from the width direction in which the suction portion 31a faces. According to this configuration, since the upstream flow path 32a can be attached to and detached from the suction unit 31a from the outside of the casing 12, the assembly work of the product, the replacement work of the component, and the maintenance work are facilitated.
As shown in fig. 2, the discharge portion 41 and the connection portion 32c are disposed at a lower position than the suction mechanism 33. Preferably, at least a part of the connection portion 32c is disposed below the suction mechanism 33. Further, the attachment portion 40 and the suction mechanism 33 are preferably arranged so as to be aligned in the depth direction such that a front portion of the attachment portion 40 and a depth portion of the suction mechanism 33 overlap each other in the vertical direction.
As shown in fig. 1 to 3, the downstream flow path 32b extending rearward from the upper portion of the suction mechanism 33 passes through an arrangement region (for example, a region on the deep side of the suction mechanism 33 and the support member 36) which does not overlap with the suction mechanism 33 and the support member 36 in the vertical direction, is bent forward, and is led to the lower side of the suction mechanism 33 and the support member 36 after direction change.
As shown in fig. 2 and 3, the portion of the downstream flow path 32b passing through the arrangement region is engaged with the guide portion 42a recessed in the wall 42, and the position thereof is fixed. The guide portion 42a is curved and groove-shaped, and a portion of the downstream flow path 32b that engages with the guide portion 42a is also curved.
As shown in fig. 2, the downstream flow path 32b led to the lower side of the suction mechanism 33 and the support member 36 is bent and changes its direction to face rearward below the suction mechanism 33 and the support member 36, and the tip end thereof becomes the connection portion 32 c.
The upstream flow path 32a of the discharge flow path 32 extending from the upper portion of the suction mechanism 33 extends forward and is led downward, and then is led between the suction mechanism 33 and the slider 35 toward the opposite initial side, and is led downward of the slider 35 after being bent in a semicircular shape and being changed in direction to the initial side. As shown in fig. 2, the upstream flow path 32a routed to the lower side of the slider 35 is connected to the suction portion 31 a.
As shown in fig. 5, the support member 36 preferably has a semicircular guide 36a engageable with the upstream flow path 32a of the discharge flow path 32 routed between the suction mechanism 33 and the slider 35. In this case, the upstream flow path 32a is formed along the guide 36a, whereby the direction can be changed compactly without bending.
As shown in fig. 4, when the inlet 20a of the liquid container 20 is disposed at a higher position than the waste liquid container 50, the cap 31, and the suction mechanism 33, the liquid injection operation is facilitated. In the case where the liquid container 20 has a stepped level difference, the extending direction of the supply channel 26 may be changed or the supply channel 26 may be routed by using a space (indicated by a two-dot chain line in fig. 4) formed by the level difference. For example, the supply flow path 26 may be bent in a space indicated by a two-dot chain line in fig. 4 to change the extending direction from the vertical direction to the horizontal direction.
Next, the operation and effect of the liquid ejecting apparatus 11 configured as described above will be described.
(1) By disposing the suction mechanism 33 above the discharge portion 41, the discharge flow path 32 can be routed in a space below the suction mechanism 33.
(2) By vertically overlapping the discharge portion 41 and the suction mechanism 33, the dimension in the depth direction can be reduced as compared with the case where both are arranged in the depth direction.
(3) Since the support member 36 unitizes the suction mechanism 33 and the cover 31, a space for routing the discharge flow path 32 can be easily secured.
(4) The discharge flow path 32, which is a flexible tube, can be deflected and displaced to change its direction, and, on the other hand, if the curvature at the time of bending is too small, it is bent. In this regard, the discharge flow path 32 is bent while being routed from the upper side to the lower side, and thus the bending can be suppressed.
(5) By making the curved portion of the downstream flow path 32b follow the guide portion 42a, the hose can be guided compactly while suppressing the bending.
(6) By engaging the downstream flow path 32b with the guide portion 42a, the bent hose can be prevented from spreading to the initial side. This allows the wall 42 and the downstream flow channel 32b to be aligned without a gap in the width direction.
(7) By disposing the suction mechanism 33 between the cover 31 and the mounting portion 40 in the depth direction, the upstream flow path 32a and the downstream flow path 32b can be routed separately forward and backward.
The above embodiment may be modified as in the modification examples described below. Note that the configurations included in the above-described embodiment and the configurations included in the following modified examples may be arbitrarily combined, or the configurations included in the following modified examples may be arbitrarily combined with each other. In the following description, elements having the same functions as those of conventional elements are denoted by the same reference numerals, and redundant description thereof is omitted.
At least one of the liquid container 20 and the waste liquid container 50 may be disposed on the initial side of the movement region of the carriage 24. In this case, a portion of the housing 12 covering at least one of the liquid container 20 and the waste liquid container 50 may protrude outward (in a direction opposite to the direction X) from the side wall 16. With this configuration, the housing 12 can be partially enlarged, thereby increasing the amount of liquid or waste liquid to be stored.
As in the modification shown in fig. 6, the liquid container 20 may be attached to and detached from the front wall 14 through an attachment/detachment port 14 b. The inlet 20a may not be provided in the liquid container 20.
As shown in a modification example shown in fig. 6, the suction mechanism 33 may not be supported by the support member 36.
As shown in the modification example shown in fig. 6, the liquid container 20, the waste liquid container 50, the lid 31, and the suction mechanism 33 may be arranged in this order from the front side toward the depth side in the depth direction in the housing 12. In this case, the waste liquid container 50 can be attached to and detached from the housing 12 through the insertion opening 16a provided in the side wall 16. In this modification, the downstream flow path 32b may be routed to the lower side of the suction mechanism 33 and the cover 31 and connected to the discharge portion 41. This allows the downstream flow path 32b to be routed by the space below the suction mechanism 33 and the cover 31. In the modification shown in fig. 6, it is preferable to dispose the discharge portion 41 at a position lower than the cover 31 and the support member 36 because the depth dimension and the height are suppressed.
As in the modification shown in fig. 6, at least one of the liquid container 20 and the waste liquid container 50 (or a part thereof) may be disposed in a region on the outer side (initial side) in the width direction than a moving region (indicated by a two-dot chain line in fig. 6) of the carriage 24.
As in the modification shown in fig. 6, a portion of the housing 12 covering at least one of the liquid container 20 and the waste liquid container 50 may protrude outward from the side wall 16. With this configuration, the housing 12 can be partially enlarged, thereby increasing the amount of liquid or waste liquid to be stored.
The liquid ejected by the liquid ejecting head 23 is not limited to ink, and may be, for example, a liquid material in which particles of a functional material are dispersed or mixed in a liquid. For example, a liquid material containing a material such as an electrode material or a color material (pixel material) in a dispersed or dissolved form, which is used for manufacturing a liquid crystal display, an EL (electroluminescence) display, a surface-emitting display, or the like, may be ejected to perform recording.
The medium S is not limited to paper, and may be a plastic film, a thin plate material, or the like, or may be a fabric used in a printing apparatus or the like. The medium S may be clothes of any shape such as T-shirts, or may be a three-dimensional object of any shape such as tableware or stationery.
