  An embodiment will be described with reference to the drawings by taking an ink jet printer (hereinafter referred to as a printer) as an example of a liquid ejecting apparatus as an example. In addition, in each drawing, in order to make each structure the size which can be recognized, the structure and the scale of a member may differ.

(First embodiment)
The printer 1 in this embodiment has a housing 2 as shown in FIG. The housing 2 constitutes the outer shell of the printer 1. The printer 1 has a tank 6, an operation panel 3, and a tank unit 5. In the present embodiment, the tank unit 5 includes four tanks 6. Note that the number of tanks 6 in the tank unit 5 is not limited to four, and a number less than four or a number exceeding four may be employed.

  The tank unit 5 is accommodated inside the housing 2. That is, the four tanks 6 of the tank unit 5 are covered with the housing 2. The operation panel 3 is disposed outside the housing 2. The operation panel 3 includes a power button 7 and a display panel 8 which is an example of a display unit. As the display panel 8, for example, a panel such as a touch panel that can accept input by a user can be employed. Thus, the operation panel 3 is an example of an operation unit that can be operated by the user. The tank 6 is an example of a liquid container. The printer 1 can perform printing on a recording medium P such as recording paper with ink that is an example of a liquid.

  In FIG. 1, XYZ axes, which are coordinate axes orthogonal to each other, are attached. The XYZ axes are also attached to the drawings shown thereafter as necessary. In the present embodiment, a state in which the printer 1 is arranged on a horizontal plane (XY plane) defined by the X axis and the Y axis is a use state of the printer 1. The posture of the printer 1 when the printer 1 is arranged on the XY plane is referred to as a usage posture of the printer 1. The Z axis is an axis orthogonal to a horizontal plane. In the use state of the printer 1, the Z-axis direction is the vertical upward direction. When the printer 1 is in use, the −Z-axis direction is the vertically downward direction in FIG. In each of the XYZ axes, the direction of the arrow indicates the + (positive) direction, and the direction opposite to the direction of the arrow indicates the-(negative) direction.

  The printer 1 is provided with a paper discharge unit 11. In the printer 1, the recording medium P is discharged from the paper discharge unit 11. In the printer 1, the surface on which the paper discharge unit 11 is provided is a front surface 13. In the present embodiment, the front surface 13 of the printer 1 is also the front surface 13 of the housing 2. The housing 2 has an upper surface 15 that intersects the front surface 13 and a side wall 17 that intersects the front surface 13 and the upper surface 15. When the front surface 13 is viewed from the front, that is, when the front surface 13 is viewed in the −Y-axis direction, the side wall 17 is positioned in the X-axis direction of the front surface 13. The housing 2 has a side wall 19 that intersects the front surface 13 and the upper surface 15 and is positioned in the −X-axis direction of the side wall 17 with the front surface 13 interposed therebetween.

  The operation panel 3 is disposed on the front surface 13 of the printer 1. The operation panel 3 is provided outside the housing 2. The outer surface of the operation panel 3 faces the Y-axis direction. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y-axis direction, the tank unit 5 is located between the operation panel 3 and the side wall 17. From another viewpoint, when the printer 1 is viewed from the front, that is, when the printer 1 is viewed in the −Y-axis direction, the tank unit 5 is positioned between the paper discharge unit 11 and the side wall 17.

  A window portion 21 is provided on the front surface 13 of the housing 2. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y-axis direction, the window portion 21 is located between the operation panel 3 and the side wall 17. In the present embodiment, a window portion 21 is provided for each tank 6. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y-axis direction, the window portion 21 is provided at a position overlapping the tank 6. In the present embodiment, the window portion 21 faces the Y axis direction.

  The window part 21 has translucency. For this reason, the user can visually recognize the four tanks 6 through the window portion 21. In this embodiment, the window part 21 is comprised with the member which has translucency. The user can visually recognize the four tanks 6 through the window portion 21 made of a member having translucency. In addition, the window part 21 should just have translucency, and may or may not be transparent. Moreover, the window part 21 is not limited to the member which has translucency, For example, you may be comprised by the opening formed in the housing | casing 2. FIG.

  In the present embodiment, at least a part of the portion facing the window portion 21 of each tank 6 has translucency. The ink in the tank 6 can be visually recognized from the translucent part of each tank 6. Therefore, the user can visually recognize the amount of ink in each tank 6 by visually recognizing the four tanks 6 through the window portion 21. That is, in the tank 6, at least a part of the portion facing the window portion 21 can be used as a visual recognition portion that can visually recognize the amount of ink.

  The housing 2 has a cover 23. The cover 23 constitutes a part of the housing 2. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y-axis direction, the cover 23 is located between the operation panel 3 and the side wall 17. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y-axis direction, the cover 23 is provided at a position overlapping the tank unit 5. The position of the tank unit 5 and the position of the cover 23 in the printer 1 can also be the position between the operation panel 3 and the side wall 19 when the operation panel 3 is viewed from the front.

  The cover 23 is disposed on the front surface 13 of the printer 1. The outer surface of the cover 23 faces the Y-axis direction. As described above, the outer surface of the operation panel 3 also faces the Y-axis direction. In the present embodiment, the outer surface of the cover 23 and the outer surface of the operation panel 3 are located in a common plane. In other words, in the usage posture of the printer 1, the position of the outer surface of the cover 23 in the Y-axis direction is the same as the position of the outer surface of the operation panel 3 in the Y-axis direction. For this reason, since the outer surface of the cover 23 and the outer surface of the operation panel 3 are located in a common plane, the appearance of the printer 1 is unlikely to be uneven. For this reason, when the printer 1 is transported or the like, it is difficult to come into contact with, catch on, or collide with articles or structures arranged in the surrounding environment. In addition, being located in a plane is not limited to conforming to a complete plane, but includes being located in a plane including unevenness due to errors, tolerances, etc., and steps such as joints between components.

  In the present embodiment, the outer surface of the front surface 13 of the housing 2 also faces the Y-axis direction. In the present embodiment, the outer surface of the front surface 13 of the housing 2 and the outer surface of the operation panel 3 are located in a common plane. In other words, in the usage posture of the printer 1, the position of the outer surface of the front surface 13 of the housing 2 in the Y-axis direction is the same as the position of the outer surface of the operation panel 3 in the Y-axis direction. For this reason, since the outer surface of the front surface 13 of the housing 2 and the outer surface of the operation panel 3 are located in a common plane, the appearance of the printer 1 is unlikely to be uneven. For this reason, when the printer 1 is transported or the like, it is difficult to come into contact with, catch on, or collide with articles or structures arranged in the surrounding environment. In addition, being located in a plane is not limited to conforming to a complete plane, but includes being located in a plane including unevenness due to errors, tolerances, etc., and steps such as joints between components.

  A structure capable of adjusting the tilt of operation panel 3 (also referred to as tilt adjustment) may be employed. If the inclination of the operation panel 3 can be adjusted, the user can view and operate the operation panel 3 at a desired inclination, which is highly convenient. In the configuration in which the inclination of the operation panel 3 can be adjusted, the outer surface of the cover 23 and the outer surface of the operation panel 3 are common when the operation panel 3 is closed, that is, when the outer surface of the operation panel 3 is orthogonal to the XY plane. Located in the plane.

  The cover 23 covers at least a part of the tank 6. The cover 23 is configured to be openable and closable with respect to the housing 2. When the cover 23 is opened with respect to the housing 2, a part of each tank 6 is exposed. The user can inject ink into each tank 6 with the cover 23 opened with respect to the housing 2. In the present embodiment, the window portion 21 is provided on the cover 23.

  As shown in FIG. 2, the printer 1 has a recording head 31 and a control unit 32. In the printer 1, the recording head 31 and the control unit 32 are accommodated in the housing 2. For this reason, in this embodiment, the recording head 31 and the tank unit 5 are accommodated in the same housing 2. That is, the housing 2 covers the recording head 31 and the tank unit 5 together. Here, in the configuration in which the tank unit 5 is disposed outside the housing 2, the mounting of the housing 2 to the printer 1 and the mounting of the tank unit 5 to the housing 2 are separate processes, so that the assemblability is improved. It tends to decline. In contrast, in the present embodiment, the housing 2 is configured to collectively cover the recording head 31 and the tank unit 5, so that the recording head 31 and the tank unit 5 are attached by attaching the housing 2. Can be collectively covered with the housing 2, so that it is easy to improve assembly.

  The recording head 31 is an example of a liquid ejecting head, and performs recording on the recording medium P by ejecting ink as ink droplets. The recording head 31 performs recording with ink, which is an example of liquid, on a recording medium P that is transported in the Y-axis direction by a transport device (not shown). A transport device (not shown) intermittently transports the recording medium P such as recording paper in the Y-axis direction. The recording head 31 is configured to be capable of reciprocating along the X axis by a moving device (not shown). The control unit 32 controls driving of each of the above components. In the present embodiment, four tanks 6 are arranged along the X axis.

  Here, the direction along the X-axis is not limited to a direction completely parallel to the X-axis, and includes directions inclined due to errors, tolerances, etc., except for a direction orthogonal to the X-axis. Similarly, the direction along the Y-axis is not limited to a direction completely parallel to the Y-axis, and includes directions inclined due to errors, tolerances, etc., except for a direction orthogonal to the Y-axis. The direction along the Z-axis is not limited to a direction completely parallel to the Z-axis, and includes directions inclined due to errors, tolerances, etc., except for a direction orthogonal to the Z-axis. In other words, the direction along any axis or plane is not limited to a direction completely parallel to any axis or plane, but may be due to errors, tolerances, etc., except for a direction perpendicular to any axis or plane. Including tilted direction.

  In the present embodiment, the plurality of tanks 6 are configured separately from each other. However, the configuration of the tank 6 which is an example of the liquid container is not limited to this. As a configuration of the liquid container, a configuration in which a plurality of tanks 6 are integrated to form one liquid container may be employed. In this case, a single liquid container is provided with a plurality of liquid containers. The plurality of liquid storage portions are individually partitioned from each other and configured to store different types of liquids. In this case, for example, different color inks can be individually stored in the plurality of liquid storage portions.

  The tank 6 contains ink that is an example of a liquid. A liquid inlet 33 is formed in the tank 6. In the tank 6, ink can be injected into the tank 6 from the outside of the tank 6 through the liquid injection port 33. A configuration in which the liquid injection port 33 is sealed with a cap (not shown) can also be employed. When injecting ink into the tank 6, the user can inject ink after opening the cap and opening the liquid injection port 33.

  In the present embodiment, the liquid inlet 33 is configured as an opening formed in the outer surface 34 that forms the outer shape of the tank 6. In the present embodiment, the outer surface 34 is inclined in the usage posture of the printer 1. The outer surface 34 is inclined in the direction toward the −Y axis direction from the −Z axis direction toward the Z axis direction. For this reason, the outer surface 34 faces in the direction intersecting the vertical direction. The outer surface 34 is an example of an end surface of the liquid inlet 33. If the outer surface 34 is oriented in a direction intersecting the vertical direction, it is difficult for foreign matters such as dust to accumulate on the outer surface 34. For this reason, it is difficult for foreign matters such as dust to adhere to the outer surface 34. Thereby, it is easy to avoid foreign matters such as dust entering the liquid inlet 33.

  The configuration of the tank 6 is not limited to the above. As a configuration of the tank 6, for example, as shown in FIG. 3, a configuration in which a tubular liquid injection portion 35 that protrudes from the outer surface of the tank 6 is provided may be employed. In this case, the liquid injection port 33 is opened at the end surface 36 of the tip portion opposite to the tank 6 side of the tubular liquid injection portion 35 protruding from the outer surface of the tank 6. Also in this configuration, a configuration in which the end face 36 is inclined is preferable from the viewpoint that foreign matters such as dust are difficult to adhere.

  As shown in FIG. 2, an ink supply tube 37 is connected to each tank 6. The ink in the tank 6 is supplied to the recording head 31 via the ink supply tube 37. The ink supplied to the recording head 31 is ejected as ink droplets from a nozzle (not shown) directed to the recording medium P side.

  In the above example, the tank unit 5 has been described as one of the components of the printer 1. However, the tank unit 5 and the printer 1 may be configured separately from each other. When the tank unit 5 and the printer 1 are configured separately from each other, the tank unit 5 is disposed outside the housing 2. That is, when the tank unit 5 and the printer 1 are configured separately from each other, the tank unit 5 is not covered with the housing 2. When the tank unit 5 and the printer 1 are configured separately from each other, for example, the tank unit 5 is housed in a housing separate from the housing 2 and the housing housing the tank unit 5 is coupled to the housing 2. Can be considered. As a method for coupling the housing containing the tank unit 5 and the housing 2, various coupling methods such as coupling by screws and coupling by fitting may be considered.

  As the tank 6, a configuration in which an upper limit mark 42, a lower limit mark 43, and the like are added to a visual recognition surface 41 that can visually recognize the amount of ink accommodated can be employed. The user can grasp the amount of ink in the tank 6 using the upper limit mark 42 and the lower limit mark 43 as marks. The upper limit mark 42 indicates a measure of the amount of ink that does not overflow from the liquid injection portion 35 when ink is injected from the liquid injection portion 35. Further, the lower limit mark 43 indicates a measure of the amount of ink when prompting ink injection. A configuration in which at least one of the upper limit mark 42 and the lower limit mark 43 is provided in the tank 6 may be employed. The viewing surface 41 faces the Y axis direction.

  In the printer 1 having the above-described configuration, the recording medium P is conveyed in the Y-axis direction, and the recording head 31 is reciprocated along the X-axis to cause the recording head 31 to eject ink droplets at a predetermined position. Recording is performed on the recording medium P. These operations are controlled by the control unit 32.

  The ink is not limited to either water-based ink or oil-based ink. The water-based ink may be either an ink having a structure in which a solute such as a dye is dissolved in an aqueous solvent or an ink having a structure in which a dispersoid such as a pigment is dispersed in an aqueous dispersion medium. The oil-based ink may be either one having a configuration in which a solute such as a dye is dissolved in an oil-based solvent or one having a configuration in which a dispersoid such as a pigment is dispersed in an oil-based dispersion medium.

  As shown in FIG. 4, the cover 23 is configured to be rotatable with respect to the housing 2 in the R1 direction in the figure. The R1 direction corresponds to a counterclockwise direction when the YZ plane is viewed from the X-axis direction with the axis along the X-axis as a rotation axis. By rotating the cover 23 in the R1 direction with respect to the housing 2, the cover 23 can be opened with respect to the housing 2. A state where the cover 23 is opened with respect to the housing 2 is referred to as an open state of the cover 23. By rotating the cover 23 in the direction opposite to the R1 direction from the opened state of the cover 23, the cover 23 can be closed with respect to the housing 2. Thus, in the present embodiment, the cover 23 is configured to be openable and closable with respect to the housing 2. A state where the cover 23 is closed with respect to the housing 2 is referred to as a closed state of the cover 23.

  Note that the appearance of the printer 1 is not limited to the texture and color expressed in FIG. As the appearance of the printer 1, for example, a printer whose surface is embossed can be used.

  The direction in which the cover 23 is opened with respect to the housing 2 is not limited to the R1 direction. The direction in which the cover 23 is opened with respect to the housing 2 is clockwise when the rotation axis along the X axis is positioned at the end in the Z axis direction of the cover 23 and the YZ plane is viewed in plan from the X axis direction. Direction can also be employed. The direction in which the cover 23 is opened with respect to the housing 2 is the opposite of when the rotation axis along the Z axis is located at the end of the X axis direction of the cover 23 and the XY plane is viewed in plan from the Z axis direction. A clockwise direction can also be employed. Further, as a direction in which the cover 23 is opened with respect to the housing 2, the rotation axis along the Z axis is positioned at the end of the cover 23 in the −X axis direction, and the XY plane is viewed in plan from the Z axis direction. A clockwise direction can also be employed.

  When the cover 23 is opened, the liquid inlet 33 of the tank 6 is exposed. For this reason, the user can access the liquid inlet 33 of the tank 6 from the outside of the housing 2. In the open state of the cover 23, the user can inject the ink stored in the bottle 47 or the like into the tank 6 from the liquid injection port 33. At this time, the user can inject ink into the liquid injection port 33 while confirming the amount of ink in the tank 6 through the viewing surface 41.

  At this time, if the horizontal state of the printer 1 is deviated, the amount of ink in the tank 6 viewed through the viewing surface 41 may be inaccurate. This is because if the horizontal state is shifted, the position of the ink liquid level with respect to the viewing surface 41 is shifted. When such a situation occurs, it is likely that the ink overflows from the liquid injection port 33 when the ink is being injected into the liquid injection port 33. Further, when the printer 1 is in use, if the horizontal state of the printer 1 is shifted in the closed state of the cover 23, the amount of ink in the tank 6 that is visible through the window portion 21 may be inaccurate. is there. If such a situation occurs, it may be possible that the ink is not supplied to the recording head 31 even though the amount of ink in the tank 6 exceeds the lower limit mark 43 (FIG. 2).

  In the present embodiment, information indicating the horizontal state of the printer 1 is displayed on the display panel 8. In other words, the display panel 8 can display the horizontal state of the printer 1. As information displayed on the display panel 8, for example, as shown in FIG. 5, an indicator 51 that indicates the horizontal state of the printer 1 is compared with an aiming line 52 that is a position when the printer 1 is horizontal. Information.

  The user can recognize the horizontal state of the printer 1 based on the information indicating the horizontal state displayed on the display panel 8. When the horizontal state of the printer 1 is shifted, the user can adjust the horizontal state of the printer 1 so that the indicator 51 displayed on the display panel 8 approaches the line of sight 52. As a result, it is easy to avoid a situation in which ink overflows from the liquid inlet 33 when ink is being injected into the liquid inlet 33 and a situation in which ink is not supplied to the recording head 31.
