1. Technical Field
The present invention relates to a recording apparatus, for example, an ink jet type printer.
2. Related Art
In the related art, there are known ink jet printers (recording apparatuses) equipped with a recording head that discharges ink, which is an example of a liquid, onto paper, which is an example medium, for recording. Among these printers, some printers include ink tanks (liquid containers) that store inks to be supplied to a recording head. For example, JP-A-2012-20495 describes a printer that includes an ink tank into which an ink can be injected through a liquid injection port provided on the ink tank.
The ink tank provided in the printer described in JP-A-2012-20495 has a plug member (blocking member) that blocks the liquid injection port to reduce leakage of the ink stored in the ink tank from the liquid injection port. In another generally known printer, an openable cover that covers a liquid injection port on which a plug member for blocking the liquid injection port is mounted so as to reduce the risk of dropping-off of the plug member due to the increase in internal pressure in the ink tank, an impact from the outside, or the like. In such a structure including the cover for covering the liquid injection port in addition to the plug member for blocking the liquid injection port, however, it is laborious to inject the ink because the cover has to be opened and then the plug member has to be removed from the liquid injection port to inject the ink into the ink tank.
An advantage of some aspects of the invention is that there is provided a recording apparatus that enables a user to inject a liquid into a liquid container without being laborious and also a blocking member for blocking an injection port provided to the liquid container for storing the liquid and a cover that covers the injection port.
Hereinafter, apparatuses for solving the aforementioned problem and their working effects will be described. A recording apparatus for solving the aforementioned problem includes a recording head configured to discharge a liquid onto a medium for recording, a casing accommodating at least the recording head, an opening and closing member openable and closable between an open position where the inside of the casing is exposed and a closed position where the inside of the casing is not exposed, at least one liquid container having a liquid storage chamber for storing the liquid to be supplied to the recording head and an injection port enabling the liquid to be injected from the outside to the inside of the liquid storage chamber, at least one blocking member configured to block the injection port by coming into contact with the injection port, and a cover provided such that the cover can be opened or closed between an open position where the injection port is exposed and a closed position where the injection port is not exposed. The number of the liquid containers is two or more and the number of the blocking members corresponds to the number of the injection ports in the liquid containers, and the blocking members are mounted on the cover.
With this structure, the contact operation and the separation operation of the blocking members for blocking the injection ports to the injection ports are performed in conjunction with the opening and closing operations of the cover that covers the injection ports of the liquid containers. That is, the blocking members can be separated from the injection ports when a user opens the cover, and consequently, the user is able to inject the liquids into the liquid storage chambers by only opening the cover. Consequently, the liquids can be injected into the liquid containers without being laborious while the blocking members for blocking the injection ports provided on the liquid containers that store the liquids and the cover that covers the injection ports are provided. The plurality of blocking members that block the plurality of injection ports respectively can be separated from the injection ports in a single operation by opening the cover. Consequently, the time and labor for injecting the liquids into the plurality of liquid containers can be reduced.

Consequently, the liquids can be injected into the liquid containers without being laborious while the blocking member for blocking the injection ports provided on the liquid containers that store the liquids and the cover that covers the injection ports are provided. The one blocking member that blocks the plurality of injection ports can be separated from the injection ports in a single operation by opening the cover. Consequently, the time and labor for injecting the liquids into the plurality of liquid containers can be reduced.
In the above-described recording apparatus, it is preferable that the blocking members are detachably mounted to the cover.
With this structure, the blocking member can be replaced as needed, for example, if the blocking member has deteriorated.
In the above-described recording apparatus, it is preferable that the blocking member be larger than the injection port and that the blocking member be composed of an elastically deformable elastic member.
With this structure, the blocking member is larger than the injection port of the liquid container, and the blocking member is capable of coming into contact in an elastically deformable manner with the injection port of the liquid container. Consequently, the sealing capability of the blocking member can be increased and the injection port can be appropriately blocked.
In the above-described recording apparatus, it is preferable that the casing further accommodate at least a portion of the liquid containers and that the cover be rotatably provided with respect to the casing. With this structure, the cover can be more readily opened or closed compared with, for example, a structure in which a cover is opened or closed by sliding the cover.
In the above-described recording apparatus, it is preferable that an engaging portion be provided in one of the cover and the casing and that a portion to be engaged, which can be engaged with the engaging portion, be provided in the other one, and that the engaging portion engage the portion to be engaged when the cover is positioned in the closed position.
With this structure, the risk of the cover readily opening in response to an impact or vibrations can be reduced by the engagement of the engaging portion with the portion to be engaged. In the above-described recording apparatus, it is preferable that the casing have a discharge port from which the medium on which recording has been performed with the recording head in the casing is to be discharged to the outside of the casing and that the liquid containers be disposed at a location corresponding to a side at which the discharge port is provided in the casing and a corner in the casing.
With this structure, the space in the casing can be efficiently used and the liquid can be readily injected into the liquid container disposed in the casing.
In the above-described recording apparatus, it is preferable that the casing include an operation section to be used to operate the recording apparatus and that the liquid containers be disposed at a location corresponding to the side at which the operation section is provided in the casing and a corner in the casing.
With this structure, the space in the casing can be efficiently used and the liquid can be readily injected into the liquid container disposed in the casing.
In the above-described recording apparatus, it is preferable that the casing include a viewing section through which the amounts of the liquids stored in the liquid storage chambers in the liquid containers can be viewed.
With this structure, the amounts of the liquids remaining in the liquid storage chambers can be checked through the viewing section, and the liquids can be injected into the liquid containers at an appropriate time.
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
Hereinafter, a multifunction peripheral that includes an ink jet type printer, which is an example of a recording apparatus, will be described with reference to the drawings. As shown in
A discharge port 17 is provided on the front surface of the case 15 where the operation section 14 is provided, and below the operation section 14. From the discharge port 17, the paper P on which recording has been performed by the recording device 12, is discharged. A discharge tray 18 that can be pulled toward the front of the recording device 12 is provided under the discharge port 17. A feed port (not shown) that is used to feed the paper P into the case 15 is provided on the back surface of the case 15. The paper P fed from the feed port into the case 15 is subjected to recording in the case 15, discharged from the discharge port 17, and placed onto the discharge tray 18. That is, the direction from the back surface toward the front surface of the recording device 12 is a transport Y direction of the paper P.
A viewing section 19 is provided on the front surface of the case 15 at a position (right side in
The liquid container 30 has a box shape and is used as a so-called ink tank that stores an ink to be used by the recording device 12 for recording to the paper P. The liquid container 30 is composed of a transparent or translucent resin through which the amount of the remaining stored ink can be viewed. An upper limit value 31 that indicates an upper limit value of the ink that the liquid container 30 can contain is marked on the front surface of the liquid container 30 that is opposite the viewing section 19 in the case 15. In the multifunction peripheral 11, the upper limit value 31 can be viewed from the outside of the case 15 through the viewing section 19.
As shown in
A recording section 40 that performs recording toward the paper P is provided in the case 15. The recording section 40 includes a carriage 42 that is provided such that the carriage 42 can reciprocate along a guide shaft 41 that extends in scanning X direction intersecting the transport Y direction of the paper P, and a recording head 43 that is mounted on a lower surface of the carriage 42, the recording head 43 discharging ink onto the paper P that faces the carriage 42. That is, the recording device 12 performs recording of characters, images, and the like onto the transported paper P by moving the carriage 42 in the scanning directions X and discharging the ink with the recording head 43. The scanning X direction that intersects the transport Y direction corresponds to the lengthwise direction of the multifunction peripheral 11.
A supply tube 32 in which an ink flows is connected to the recording section 40. While one end of the supply tube 32 that extends into the case 15 is connected to the recording section 40, the other end is connected to the liquid container 30. That is, the recording section 40 and the liquid container 30 are connected via the supply tube 32, and through the supply tube 32, the ink stored in the liquid container 30 is supplied to the recording section 40. Each supply tube 32 is connected to each corresponding liquid container 30, however, for the sake of simplicity, only one supply tube 32 is shown.
As shown in
A cover 50 that covers the injection ports 34 from above is provided at a position above the liquid containers 30 and opposite the injection ports 34. A top view of the recording device 12 illustrates that the cover 50 can be opened or closed at two positions; an open position (see
The cover 50 has an exterior surface 51 that is a part of the exterior of the recording device 12 and is flush with the front surface of the case 15 when the cover 50 is positioned in the closed position. Blocking members 52 that make contact with and block the injection ports 34 are mounted to a surface of the cover 50 that faces the injection ports 34 when the cover 50 is in the closed position. That is, the surface of the cover 50 that faces the injection ports 34 in
As shown in
The blocking member 52 that is mounted on each corresponding protrusion 54 has a substantially hemispherical dome shape and is composed of an elastic member (for example, an elastomer such as a rubber) that can be elastically deformed (see
A finger hook portion 55 for a user to place a finger on the portion is formed as a cutout on the surface opposite to the mounting surface 53 on which the blocking members 52 are mounted in the cover 50. In other words, the surface on which the finger hook portion 55 is formed in the cover 50 serves as a finger hook formed surface 56, and the finger hook portion 55 is formed at a central portion in the scanning X direction and close to the opening of the cover 50 on the finger hook formed surface 56. The finger hook formed surface 56 has an inclined surface that is inclined from the finger hook portion 55 toward the exterior surface 51.
As shown in
In addition, on both side surfaces of the cover 50, a cylindrical shaft 58 that extends in the scanning X direction is provided at a diagonal position of the engaging portions 57, that is, at a position close to the exterior surface 51 and close to the mounting surface 53 of the cover 50.
As shown in
As shown in
Now, the operation of the multifunction peripheral 11 that has the above-described structure, specifically, the operation of the cover 50 that covers the injection ports 34 of the liquid containers 30 provided in the recording device 12 will be described. As shown in
The blocking members 52, which are composed of an elastic member that can be elastically deformed, are pressed against the injection ports 34 and come in close contact with the injection ports 34 to block the injection ports 34 with the increased sealing capability against the injection ports 34. As shown in
As shown in
As shown in
In response to the movement of the cover 50 to the open position, the blocking members 52 that have been in contact with the injection ports 34 are separated from the injection ports 34 and the injection ports 34 are opened. That is, by the only single operation of opening the cover 50, both the cover 50 that covers the injection ports 34 of the liquid containers 30 and the blocking members 52 that block the injection ports 34 are separated from the injection ports 34 and the injection ports 34 are opened, and thereby the inks can be injected into the liquid storage chambers 33.
When the ink injection into the liquid containers 30 is completed, it is preferable to block the injection ports 34 with the blocking members 52 and cover the blocked injection ports 34 with the cover 50 to reduce drying of the inks and mixing of airborne dust into the inks in the liquid storage chambers 33 via the injection ports 34. The blocking members 52 that can block the injection ports 34 are mounted on the cover 50, and consequently, if a user tries to make the blocking members 52 come into contact with the injection ports 34 to block the injection ports 34, the cover 50 is moved from the open position to the closed position in conjunction with the movement. That is, by the only single operation of closing the cover 50, the cover 50 covers the injection ports 34 and the blocking members 52 come into contact with the injection ports 34, and thereby the injection ports 34 are blocked. Consequently, in the recording device 12 provided in the multifunction peripheral 11, the injection ports 34 can be opened or blocked in conjunction with the opening or closing operation of the cover 50 that covers the injection ports 34 of the liquid containers 30.
According to the above-described embodiment, the following advantages can be achieved.
(1) The contact operation or the separation operation of the blocking members 52 for blocking the injection ports 34 are performed to the injection ports 34 in conjunction with the opening or closing operations of the cover 50 that covers the injection ports 34 of the liquid containers 30. That is, the blocking members 52 can be separated from the injection ports 34 when a user opens the cover 50, and consequently, the user is able to inject the inks into the liquid storage chambers 33 by only opening the cover 50. Consequently, liquids can be injected into the liquid containers 30 without being laborious while the blocking members 52 for blocking the injection ports 34 provided on the liquid containers 30 that store the liquids and the cover 50 that covers the injection port 34 are provided.
(2) The blocking members 52 that are mounted on the mounting surface 53 of the cover 50 are detachable, and the blocking member 52 can be replaced as needed, for example, if the blocking member 52 has deteriorated.
(3) The blocking members 52 are capable of coming into contact in an elastically deformable manner with the injection ports 34 of the liquid containers 30, and thereby the sealing capability of the blocking members 52 can be increased and the injection ports 34 can be appropriately blocked.
(4) The plurality of blocking members 52 that block the plurality of injection ports 34 respectively can be separated from the injection ports 34 in a single operation by opening the cover 50, and thereby time and labor for injecting liquids into the plurality of liquid containers 30 can be reduced.
(5) The cover 50 can be more readily opened or closed by rotating the cover 50 about the shaft 58 compared with, for example, a structure in which a cover is opened or closed by sliding the cover.
(6) The risk of the cover 50 readily opening in response to an impact or vibrations can be reduced by the engagement of the engaging portion 57 with the portion to be engaged 22.
(7) The amounts of inks remaining in the liquid storage chambers 33 can be checked through the viewing section 19 and the inks can be injected into the liquid containers 30 at an appropriate time.
(8) The sealing capability of the blocking members 52 to the injection ports 34 can be further increased by the spiral spring 59.
(9) The upper limit of the ink the liquid storage chamber 33 can contain can be checked with the upper limit value 31 marked on the liquid container 30. Consequently, the ink can be prevented from overflowing from the injection port 34 due to excessive ink injection when the ink is injected into the liquid storage chamber 33 via the injection port 34.
(10) The liquid container 30 is disposed on the front surface side of the case 15 and at an end portion (in

In the above-described embodiment, the recording section 40 is not limited to the serial head type in which the recording section 40 moves in the scanning X directions with respect to the paper P, and alternatively, a line head type in which the recording section 40 that is long in the scanning X directions is provided may be employed.
In the above-described embodiment, the recording device 12 may be a fluid ejection apparatus that ejects or discharges a fluid (for example, liquids, liquid materials containing particles of a functional material dispersed or mixed in a liquid, and fluid materials such as gels) other than inks for recording. For example, the recording device 12 may be a liquid material ejecting apparatus that ejects a liquid material containing a dispersed or dissolved material such as an electrode material or a color material (pixel material) used for manufacturing liquid crystal displays, electroluminescence (EL) displays, or field emission displays (FEDs) for recording. Alternatively, the recording device 12 may be a fluid ejecting apparatus that ejects a fluid material such as a gel (for example, a physical gel). The present invention may be applied to any one of the fluid ejecting apparatuses. In this specification, “fluid” implies a concept that does not include fluids that consist of only gas, and the fluid includes, for example, liquids (including inorganic solvents, organic solvents, solutions, liquid resins, liquid metals (metallic melts), and the like), liquid materials, and fluid materials.
