Detailed Implementation

[0020] Implementation

[0021] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0022] Overview of the printing apparatus

[0023] First, an overview of the printing apparatus involved in the implementation method will be described.

[0024] The printing apparatus according to the embodiment includes a printing section, a mounting section, and a cover. The printing section prints on a printing medium. The mounting section is a component that allows for the attachment and detachment of a liquid container having a liquid storage section, which stores liquid supplied to the printing section. The cover switches the state of the mounting section between an open state (with the mounting section open) and a closed state (with the mounting section closed). Furthermore, the mounting section or the liquid container includes a force-applying member that applies force to the liquid container in a first direction orthogonal to the vertical direction from the mounting section toward the cover. The liquid container also includes a first limiting section and an operating section. The first limiting section is located on the upper part of the liquid container in the vertical direction, limiting the removal of the liquid container from the mounting section. The operating section is located on the upper part of the liquid container in the vertical direction and, when the liquid container is already mounted on the mounting section, is positioned closer to the cover than the first limiting section; the operating section receives an operation to release the first limiting section. The cover also includes a second limiting section. The second limiting section limits the movement of the liquid container in the first direction during the removal of the liquid container mounted on the mounting section from the mounting section in the first direction. The liquid container also includes a connecting section. The connecting portion connects to the connected portion provided on the mounting portion and is used to supply liquid. Therefore, even when the movement of the liquid container in the first direction is restricted by the second limiting portion, the connecting portion and the connected portion remain connected. As a result, the printing apparatus can prevent liquid leakage between the connecting portion and the connected portion when the liquid container is removed from the mounting portion.

[0025] The configuration of the printing apparatus according to the embodiments will be described in detail below.

[0026] Composition of printing apparatus

[0027] Hereinafter, the configuration of the printing apparatus according to the embodiment will be described using printing apparatus 1 as an example.

[0028] Figure 1 This is a diagram showing an example of the appearance of the printing apparatus 1.

[0029] Here, the three-dimensional coordinate system TC is a three-dimensional rectangular coordinate system that indicates the orientation of each figure plotted in the three-dimensional coordinate system TC. For ease of explanation, the X-axis in the three-dimensional coordinate system TC will be simply referred to as the X-axis. Similarly, for ease of explanation, the Y-axis in the three-dimensional coordinate system TC will be simply referred to as the Y-axis. Furthermore, for ease of explanation, the Z-axis in the three-dimensional coordinate system TC will be simply referred to as the Z-axis.

[0030] Furthermore, as an example, the following explanation will focus on the case where the negative direction of the Z-axis coincides with the vertical direction. It should be noted that the vertical direction can also be referred to as the direction of gravity. For ease of explanation, the positive direction of the Z-axis will be referred to as the upward direction or simply "up," and the negative direction of the Z-axis will be referred to as the downward direction or simply "downward." For ease of explanation, among the surfaces of the printing apparatus 1, the surface on the positive Z-axis side will be called the upper surface, and the surface opposite to the upper surface will be called the lower surface. For ease of explanation, among the surfaces of the printing apparatus 1, the surface on the positive X-axis side will be called the front surface, and the surface opposite to the front surface will be called the rear surface. For ease of explanation, among the surfaces of the printing apparatus 1, the surface on the positive Y-axis side will be called the left surface, and the surface opposite to the left surface will be called the right surface.

[0031] Printing apparatus 1 is an inkjet printer that prints images on a printing medium using ink supplied from an ink cartridge IC. If printing apparatus 1 is an inkjet printer, it can also be any type of printer.

[0032] The printing apparatus 1 includes a printing section 11, a mounting section 12, and a cover 13.

[0033] The printing section 11 includes an inkjet printhead, which is a component that prints images onto a printing medium using ink supplied from an ink cartridge IC. Figure 1 In order to simplify the diagram, the printing section 11 located inside the printing apparatus 1 is shown as a cuboid-shaped object.

[0034] The mounting section 12 is a component capable of loading and unloading one or more ink cartridge ICs. The mounting section 12 is configured to include a recess 121, which forms a space for inserting one or more ink cartridge ICs from the outside. The recess 121 is formed on the housing of the printing apparatus 1 as a recess extending from the front surface of the printing apparatus 1 towards the rear surface. Therefore, one or more ink cartridge ICs can be inserted from the front surface of the printing apparatus 1 towards the rear surface into the space surrounded by the inner wall of the recess 121. Furthermore, this space is openable and closable via the cover 13. Hereinafter, for ease of explanation, this space will be referred to as the ink cartridge insertion space.

[0035] Here, when one or more ink cartridge ICs are installed in the mounting section 12, each ink cartridge IC is inserted into the ink cartridge insertion space facing the negative direction of the X-axis. On the other hand, when one or more ink cartridge ICs are removed from the mounting section 12, each ink cartridge IC is pulled out of the ink cartridge insertion space facing the positive direction of the X-axis. Therefore, for ease of explanation, the positive direction of the X-axis will be referred to as the removal direction, and the negative direction of the X-axis will be referred to as the installation direction.

[0036] The following is an example, such as Figure 1 As shown, the case where the mounting section 12 can accommodate four ink cartridge ICs will be explained. Therefore, in Figure 1 In the example shown, four ink cartridge ICs are inserted into the ink cartridge insertion space. These four ink cartridge ICs are for cyan, magenta, yellow, and black inks. For ease of explanation, the ink cartridge IC for cyan ink will be referred to as Ink Cartridge ICR below. Furthermore, for ease of explanation, the ink cartridge IC for magenta ink will be referred to as Ink Cartridge ICG below. Furthermore, for ease of explanation, the ink cartridge IC for yellow ink will be referred to as Ink Cartridge ICB below. Furthermore, for ease of explanation, the ink cartridge IC for black ink will be referred to as Ink Cartridge ICK below.

[0037] Each of the four ink cartridge ICs is an example of the aforementioned liquid container. Furthermore, the ink contained in each of the four ink cartridge ICs is an example of liquid stored in a liquid reservoir within the liquid container. Each of the four ink cartridge ICs has an internal liquid reservoir TK for storing ink.

[0038] Here, refer to Figures 2-4 The structure of the ink cartridge ICR will be explained. It should be noted that the structures of ink cartridges ICG, ICB, and ICK are the same as those of the ink cartridge ICR. Therefore, the individual structures of ink cartridges ICG, ICB, and ICK will not be described.

[0039] Figure 2 This diagram shows an example of the configuration of an ink cartridge ICR with it installed in the mounting section 12. Additionally, Figure 3 yes Figure 2 The image shown is a 3D view of the ICR ink cartridge. Additionally, Figure 4 It cuts along a surface parallel to the XZ plane in the three-dimensional coordinate system TC. Figure 2 The image shows a cross-sectional view of the ink cartridge during ICR. It should be noted that... Figure 2 In the middle, the ink cartridge insertion space is closed by cover 13.

[0040] The ink cartridge ICR is roughly rectangular in shape. The ink cartridge ICR includes a liquid storage section TK, a connection section CN1, a first limiting section LM1, a tilting section TP, an operating section CL, and an opening valve VL.

[0041] The liquid storage unit TK is a component that stores the ink supplied to the printing unit 11. The ink stored in the liquid storage unit TK is supplied to the printing unit 11 via the connecting part CN, described later. Figure 2 In the diagram, to simplify the illustration, the liquid reservoir TK of the ink cartridge ICR is shown as a quadrilateral object. Additionally, in... Figure 3 In order to simplify the diagram, the liquid storage section TK has been omitted.

[0042] The connecting part CN1 is connected to the connected part CN2 provided in the mounting part 12, and ink is supplied to the printing apparatus 1 via the connected part CN2. In this example, as described above, four ink cartridges IC are mounted in the mounting part 12. Therefore, the mounting part 12 is provided with connected parts CN2 that are connected to the connecting parts CN1 of each of the four ink cartridges IC. The connected parts CN2 provided in the mounting part 12 have pins ND that are inserted into the connecting part CN1. The ink of the ink cartridges IC mounted in the mounting part 12 is supplied to the printing part 11 via the pins ND. Therefore, the connecting part CN1 has an insertion port HL for such pins ND to be inserted. The pins ND of the connected part CN2 connected to the connecting part CN1 of the ink cartridge ICR extend in a direction parallel to the X-axis. Therefore, when the ink cartridge ICR is inserted into the ink cartridge insertion space in the mounting direction, the pins ND of the connected part CN2 connected to the connecting part CN1 of the ink cartridge ICR are inserted into the insertion port HL of the connecting part CN1.

[0043] Here, the connector CN1 is an elastomer made of an elastic material. Furthermore, the pin ND, which inserts into the insertion port HL of the connector CN1, is made of a soft material capable of elastic deformation according to the movement of the ink cartridge ICR within the cartridge insertion space when inserted into the insertion port HL of the connector CN1. Therefore, plastic deformation of both the connector CN1 and the pin ND during the installation process of the ink cartridge ICR onto the mounting portion 12 or during the removal process of the ink cartridge ICR from the mounting portion 12 is suppressed.

[0044] Furthermore, the connecting part CN1 includes a force-applying component SP. The force-applying component SP is a component that applies force to the ink cartridge ICR mounted on the mounting part 12 in the removal direction. The force-applying component SP is, for example, a spring, but it can also be replaced by other force-applying components capable of applying force to the ink cartridge ICR mounted on the mounting part 12 in the removal direction. Such a force-applying component SP assists the user in removing the ink cartridge ICR from the mounting part 12. In other words, by including the force-applying component SP in the connecting part CN1, the user can easily remove the ink cartridge ICR from the mounting part 12. Figure 4 In the example shown, the force-applying component SP is provided on the connecting part CN1 between the main body of the ink cartridge ICR and the connecting part CN1. It should be noted that the force-applying component SP may also be configured to be provided on the cover 13, the mounting part 12, etc., in a manner that allows it to apply force to the ink cartridge ICR mounted on the mounting part 12 in the removal direction, instead of being provided on the connecting part CN1.

[0045] A first limiting part LM1 is provided on the upper part of the ink cartridge ICR to restrict the removal of the ink cartridge ICR from the mounting part 12. The first limiting part LM1 is a protruding part that protrudes upward from the upper part of the ink cartridge ICR, which is approximately cuboid in shape. The surface of the first limiting part LM1 that is closest to the front surface of the printing device 1 is the surface on which a wire provided in the ink cartridge insertion space is hooked. Hereinafter, for ease of explanation, this surface will be referred to as the first limiting surface. When the ink cartridge ICR is installed in the mounting part 12 by inserting the ink cartridge ICR into the ink cartridge insertion space, the wire is hooked onto the first limiting surface. As a result, the ink cartridge ICR is restricted from moving in the removal direction by the wire.

[0046] The tilting part TP is located at the lower part of the ink cartridge ICR and below the operating part CL. When the ink cartridge ICR is installed in the mounting part 12, it tilts upwards in the vertical direction as it gets closer to the cover 13. Therefore, when the operating part CL (described later) is pressed down from top to bottom, the ink cartridge ICR can rotate relative to the connection position where the connecting part CN1 and the connected part CN2 are connected by an amount corresponding to the gap between the tilting part TP and the lower surface of the ink cartridge insertion space. With this rotation, the tilting part TP contacts the lower surface of the ink cartridge insertion space. Therefore, when the ink cartridge ICR is removed from the mounting part 12, the tilting part TP is guided by the lower surface of the recess 121 forming the ink cartridge insertion space. Hereinafter, for ease of explanation, the lower surface of the recess 121 will be referred to as the first guide part GD3. The first guide part GD3 has a surface that is approximately parallel to the XY plane in the three-dimensional coordinate system TC, and the tilting part TP is guided to be approximately parallel to this XY plane. It should be noted that "a surface is approximately parallel to the XY plane" means that even if the surface is tilted by a few degrees relative to the XY plane, it is still considered parallel to the XY plane. Furthermore, "a surface is approximately parallel to the XY plane" means that even if the surface has some irregularities or bumps relative to the XY plane, it is still considered parallel to the XY plane.

[0047] It should be noted that the mounting part 12 may also have other guide parts that guide the tilting part TP as the first guide part GD3.

[0048] Because of the tilting portion TP, the restriction of the first limiting portion LM1 is released in response to the operation of the operating portion CL, which is tilted downwards in a direction more than the removal direction. For example, when the operating portion CL1 is pressed down from above, the ink cartridge ICR rotates around the aforementioned connection position. More specifically, in this case, the ink cartridge ICR rotates between a limiting position and a releasing position. The limiting position is the position where movement from the mounting portion 12 toward the cover 13, i.e., the removal direction, in a direction orthogonal to the vertical direction, is restricted by the first limiting portion LM1. The releasing position is the position where the restriction of the first limiting portion LM1 is released and the tilting portion TP contacts the first guide portion GD3. Thus, in response to operating the operating portion CL in a direction more than the removal direction, the restriction of the first limiting portion LM1 is released. As a result, the printing apparatus 1 can prevent the user from moving the ink cartridge ICR in the removal direction by force through the operation of the operating portion CL.

[0049] The operating unit CL is located on the upper part of the ink cartridge ICR, and when the ink cartridge ICR is installed in the mounting part 12, it is positioned closer to the cover 13 than the first restricting part LM1, receiving the operation to release the restriction of the first restricting part LM1. For example, when the user presses the operating unit CL from top to bottom, the ink cartridge ICR rotates from the restricted position to the released position around the aforementioned connection position. As a result, the wire hooked to the first restricting part LM1 disengages from the first restricting part LM1. Consequently, the ink cartridge ICR can be guided along the first guide part GD3 and moved in the removal direction. That is, the user can remove the ink cartridge ICR from the mounting part 12.

[0050] The opening valve VL switches between the open state (open) and the closed state (closed) states of the ink cartridge ICR, which connect the inside and outside of the liquid reservoir TK. When the ink cartridge ICR is installed in the mounting part 12, the opening valve VL is moved by the protrusion on the mounting part 12, switching the state of the ink cartridge ICR from the closed state to the open state. Here, when the ink cartridge ICR is in the open state, the pressure inside the liquid reservoir TK is atmospheric pressure. Therefore, the ink stored inside the liquid reservoir TK is compressed by atmospheric pressure and supplied to the printing device 1 through the needle ND of the insertion port HL of the insertion connection part CN1. On the other hand, when the ink cartridge ICR is removed from the mounting part 12, the opening valve VL switches the state of the ink cartridge ICR from the open state to the closed state. As a result, ink leakage from the ink cartridge ICR through the connection part CN1 can be suppressed.

[0051] Here, in Figures 2-4In the example shown, the opening valve VL overlaps with the first limiting portion LM1 in the width direction, which is orthogonal to both the removal direction and the vertical direction. In other words, in this example, the opening valve VL is surrounded by the first limiting portion LM1 in the width direction. This prevents the opening valve VL from switching the ink cartridge ICR from the off state to the open state unexpectedly by the user. It should be noted that the opening valve VL can also be configured not to overlap with the first limiting portion LM1 in the width direction.

[0052] The cover 13 switches the state of the mounting part 12 between an open state (open mounting part 12) and a closed state (closed mounting part 12). When the mounting part 12 is in the closed state, as follows... Figure 5 As shown, the ink cartridge insertion space is closed by cover 13 and cannot be seen from the outside of the printing device 1. Here, Figure 5 This is a diagram showing an example of the appearance of the printing apparatus 1 when the mounting section 12 is in the closed state by closing the ink cartridge insertion space with the cover 13. Figure 5 As shown, when the ink cartridge insertion space is closed by cover 13, the user cannot touch any of the four ink cartridge ICs. Therefore, in this situation, the user cannot install or remove any of the four ink cartridge ICs from the mounting section 12. On the other hand, when the mounting section 12 is open, the ink cartridge insertion space is opened by cover 13 and can be seen from the outside of the printing apparatus 1. Therefore, in this situation, the user can install or remove any of the four ink cartridge ICs from the mounting section 12.

[0053] here, Figure 6 This diagram shows an example of four ink cartridge ICs installed in the mounting section 12. Next, Figure 7 This indicates pressing down from top to bottom. Figure 6 This diagram illustrates an example of the operation section CL of the ink cartridge ICR among the four ink cartridge ICs shown. For example, when the user presses the operation section CL from top to bottom, as... Figure 7 As shown, the ink cartridge ICR rotates from the restricted position to the released position, centered on the aforementioned connection position. As a result, the tilting portion TP contacts the first guide portion GD3. Figure 7The diagram shows the situation where the inclined portion TP of the ink cartridge ICR contacts the first guide portion GD3. When the inclined portion TP contacts the first guide portion GD3, the inclined portion TP is guided by the first guide portion GD3 when the user pulls out the ink cartridge ICR in the removal direction. As a result, the pin ND of the connected portion CN2, which is connected to the connecting portion CN1 of the ink cartridge ICR, is pulled out from the insertion port HL of the connecting portion CN1 of the ink cartridge ICR. Thus, the ink cartridge ICR is removed from the mounting portion 12. However, when the ink cartridge ICR is forcefully removed from the mounting portion 12, ink may sometimes leak from between the connecting portion CN1 and the connected portion CN2. Such ink leakage can cause ink to adhere to the periphery of the printing apparatus 1 on which the ink cartridge ICR is mounted, which is undesirable.

[0054] Therefore, the cover 13 has a second limiting part LM2 that restricts the movement of the ink cartridge IC in the removal direction during the removal process of the ink cartridge IC installed in the mounting part 12 from the mounting part 12 in the removal direction.

[0055] like Figure 8 As shown, the second limiting part LM2 is a component that restricts the movement of the ink cartridge IC in the removal direction during the removal process of the ink cartridge IC installed in the mounting part 12 from the mounting part 12 in the removal direction. Figure 8 This diagram illustrates an example of an ink cartridge ICR being restricted from moving in the removal direction during the removal process by the second restrictor LM2. The second restrictor LM2 can be any component, capable of restricting the movement of the ink cartridge ICR in the removal direction during the removal process. Figure 8 In the example shown, the second limiting part LM2 is a rectangular plate-shaped component that restricts the movement of the ink cartridge ICs in the removal direction during the removal of each of the four ink cartridge ICs. By providing such a second limiting part LM2 on the cover 13, the printing apparatus 1 can prevent the ink cartridge ICs from being forcefully removed from the mounting part 12. As a result, the printing apparatus 1 can prevent ink leakage from between the connecting part CN1 and the connected part CN2 when the ink cartridge ICs are removed from the mounting part 12.

[0056] here, Figure 9 This diagram illustrates an example of the relative positional relationship between the ink cartridge ICR and the second limiting part LM2 when the mounting part 12 is in the open state and the ink cartridge ICR is installed in the mounting part 12. In this case, as... Figure 9 As shown, the connecting part CN1 of the ink cartridge ICR is connected to the connected part CN2 of the mounting part 12. Furthermore, in this case, the ink cartridge ICR does not contact the second limiting part LM2.

[0057] Figure 10 This indicates pressing down from top to bottom. Figure 9The diagram shows an example of the relative positional relationship between the ink cartridge ICR and the second limiting part LM2 during the operation of the ink cartridge ICR's operating section CL. In this case, as described above, the ink cartridge ICR rotates from the limiting position to the releasing position with the connection position as the center. Therefore, in Figure 10 In the example shown, the tilting portion TP of the ink cartridge ICR contacts the first guide portion GD3. However, even in this case, the ink cartridge ICR is separated from the second limiting portion LM2. This is because, during such rotation, the ink cartridge ICR does not move in the removal direction. As a result, during such rotation, as... Figure 10 As shown, the connection between the connecting part CN1 of the ink cartridge ICR and the connected part CN2 of the mounting part 12 is maintained.

[0058] It should be pointed out that, such as Figure 10 As shown, when the ink cartridge ICR rotates from the restricted position to the released position, the connecting part CN1 contacts the lower part of the connected part CN2. This is because, as mentioned earlier, the connecting part CN1 is an elastomer made of synthetic rubber. Therefore, when the connecting part CN1 contacts the lower part of the connected part CN2, even if ink leaks from the connected part CN2, the leaked ink will be wiped away by the connecting part CN1. That is, such contact between the lower part of the connecting part CN1 and the connected part CN2 can more reliably prevent ink leakage from between the connecting part CN1 and the connected part CN2.

[0059] Furthermore, before the aforementioned opening valve VL is restricted by the second restricting part LM2 during the removal process, it switches the state of the ink cartridge ICR from the open state to the closed state. As a result, the printing apparatus 1 can reduce the possibility of ink leakage between the connecting part CN1 and the connected part CN2 when the ink cartridge ICR is pulled out from the mounting part 12.

[0060] Figure 11 It shows that Figure 10 This diagram illustrates an example of the relative positional relationship between the ink cartridge ICR and the second limiting part LM2 when the cartridge ICR is moved in the removal direction. Figure 11 As shown, when making Figure 10 When the ink cartridge ICR moves in the removal direction, it contacts the second limiting part LM2, thus restricting its movement in the removal direction. As a result, the printing apparatus 1 can prevent the ink cartridge IC from being forcefully removed from the mounting part 12. Furthermore, as shown... Figure 11As shown, in the printing apparatus 1, when the ink cartridge ICR is in contact with the second limiting part LM2, that is, when the ink cartridge ICR is restricted from moving in the removal direction by the second limiting part LM2, the connection between the connecting part CN1 and the connected part CN2 is maintained. Therefore, even if the ink cartridge ICR is forcefully contacted with the second limiting part LM2, ink will not leak from between the connecting part CN1 and the connected part CN2. In other words, the printing apparatus 1 can suppress ink leakage from between the connecting part CN1 and the connected part CN2 when the ink cartridge ICR is removed from the mounting part 12.

[0061] To prevent ink leakage between the connecting part CN1 and the connected part CN2, such as Figure 10 As shown, the length L1 of the area where the connecting part CN1 and the connected part CN2 overlap in the removal direction needs to be longer than the length L2 that the ink cartridge ICR, when mounted on the mounting part 12, can move in the removal direction before being restricted by the second restricting part LM2 during removal. When the length L1 is longer than the length L2, even if the ink cartridge ICR is moved in the removal direction until it contacts the second restricting part LM2 during removal, the connection between the connecting part CN1 and the connected part CN2 will be maintained. Therefore, the printing apparatus 1 can suppress ink leakage between the connecting part CN1 and the connected part CN2.

[0062] After the second limiting part LM2 restricts movement in the removal direction, the user can release the restriction of the second limiting part LM2 on the movement of the ink cartridge ICR in the removal direction by moving the ink cartridge ICR in a direction different from the removal direction. In other words, the restriction of the second limiting part LM2 is released by moving the ink cartridge ICR in a direction different from the removal direction. For example, after the second limiting part LM2 restricts movement in the removal direction, the user can rotate the ink cartridge ICR about the connection position by moving the ink cartridge ICR upward. Here, the connection position is located near the end of the ink cartridge ICR on the mounting direction side. Therefore, the user can release the restriction of the second limiting part LM2 on the movement of the ink cartridge ICR in the removal direction by rotating the ink cartridge ICR only slightly. In this way, after the restriction of the second limiting part LM2 is released, the user can remove the ink cartridge ICR from the mounting part 12 by pulling the ink cartridge ICR out of the mounting part 12 in a direction higher than the removal direction. Therefore, compared to the case where the ink cartridge ICR is simply pulled out in the removal direction and removed from the mounting section 12, the printing device 1 can prevent the user from accidentally removing the ink cartridge ICR from the mounting section 12.

[0063] Furthermore, in this embodiment, when the mounting portion 12 is in the closed state, the second limiting portion LM2 protrudes towards the lower part of the ink cartridge IC in the vertical direction, thus limiting the vertical movement of each of the four ink cartridge ICs. More specifically, in this embodiment, when the mounting portion 12 is in the closed state, the second limiting portion LM2 protrudes towards the lower part of the ink cartridge IC in the vertical direction, as follows: Figure 2 As shown, the second limiting part LM2 is located between the inclined portion TP of the ink cartridge ICR and the first guide portion GD3 of the mounting portion 12. Therefore, the second limiting part LM2 can prevent the ink cartridge ICR from rotating from the limiting position to the released position unexpectedly by the user. Furthermore, this prevents the printing apparatus 1 from increasing in the longitudinal direction in proportion to the length of the second limiting part LM2. It should be noted that the second limiting part LM2 can also be configured not to restrict the vertical movement of some or all of the four ink cartridges IC. Additionally, the second limiting part LM2 can also be configured to abut against the inclined portion TP of the ink cartridge ICR when the mounting portion 12 is in the closed state.

[0064] It should be noted that the second limiting part LM2 can also be a component capable of switching between an upright state and a folded state. In this case, for example, when the state of the mounting part 12 is switched from closed to open by the cover 13, the second limiting part LM2 switches from a folded state to an upright state; when the state of the mounting part 12 is switched from open to closed by the cover 13, it switches from an upright state to a folded state. Such a configuration of the second limiting part LM2 can be achieved, for example, by various mechanisms such as rack and pinion, linkage, etc., or by other methods. Thus, the printing apparatus 1 can suppress interference between the second limiting part LM2 and the ink cartridge IC, and also suppress the increase in the size of the second limiting part LM2 in the front-to-back direction relative to its length. Alternatively, the second limiting part LM2 can be configured to be provided on the mounting part 12, etc., instead of being provided on the cover 13.

[0065] In addition, in this embodiment, the cover 13 is provided with a third limiting part LM3.

[0066] like Figure 2 As shown, the third limiting part LM3 protrudes towards the operating part CL when the mounting part 12 is in the closed state, and limits the movement of each of the four ink cartridge ICs. The third limiting part LM3 can be any part that protrudes towards the operating part CL when the mounting part 12 is in the closed state. Figure 1 as well as Figure 2 In the example shown, the third limiting part LM3 is a rectangular flat plate-shaped component that restricts the movement of each of the four ink cartridge ICs. Furthermore, when the mounting part 12 is in the open state, the third limiting part LM3 is located further away from the ink cartridge ICs in the first direction than the second limiting part LM2.

[0067] Here, as Figure 2 As shown, when the mounting section 12 is in the closed state, the third limiting section LM3 is located in the gap between the cartridge ICR housing and the operating section CL. Therefore, the third limiting section LM3 restricts the movement of the cartridge ICR to prevent rotation of the cartridge ICR caused by pressing the operating section CL from top to bottom. As a result, the third limiting section LM3, together with the second limiting section LM2, can more reliably suppress the cartridge ICR from rotating from the limiting position to the released position at unexpected times and for some reason.

[0068] It should be noted that the cover 13 can also be configured without the third limiting part LM3. Even in this case, the printing apparatus 1 can still prevent the ink cartridge ICR from rotating from the limiting position to the releasing position at an unexpected time due to some reason by means of the second limiting part LM2.

[0069] In summary, the printing apparatus 1 includes: a printing unit 11 for printing on a printing medium; a mounting unit 12 for mounting and dismounting an ink cartridge IC having a liquid storage unit TK, the liquid storage unit TK storing ink supplied to the printing unit 11; and a cover 13 for switching the state of the mounting unit 12 between an open state and a closed state, wherein the mounting unit 12 or the ink cartridge IC has a force-applying member SP that applies force to the ink cartridge IC in a removal direction from the mounting unit 12 toward the cover 13 in a direction orthogonal to the vertical direction, and the ink cartridge IC includes: a first limiting part LM1 disposed on the upper part of the ink cartridge IC in the vertical direction to limit the removal of the ink cartridge IC from the mounting unit 12; and an operation unit CL. The ink cartridge IC is positioned on the upper part of the vertically oriented part, and when the ink cartridge IC is installed in the mounting part 12, it is located closer to the cover 13 than the first limiting part LM1. It receives the operation of releasing the first limiting part LM1. The cover 13 has a second limiting part LM2 that restricts the movement of the ink cartridge IC in the removal direction during the removal process from the mounting part 12. The ink cartridge IC has a connecting part CN1 connected to a connected part CN2 provided in the mounting part 12. The connecting part CN1 supplies ink. When the movement of the ink cartridge IC in the removal direction is restricted by the second limiting part LM2, the connecting part CN1 and the connected part CN2 remain connected. Therefore, the printing apparatus 1 can prevent ink leakage from between the connecting part CN1 and the connected part CN2 when the ink cartridge IC is removed from the mounting part 12.

[0070] Alternatively, in the printing apparatus 1, the following configuration may be adopted: when the mounting part 12 is in the closed state, the second limiting part LM2 protrudes towards the lower part of the ink cartridge IC in the vertical direction.

[0071] Alternatively, in the printing apparatus 1, the following configuration may be adopted: the ink cartridge IC has a tilting portion TP, which is disposed at the lower part of the ink cartridge IC in the vertical direction and located below the operation portion CL. When the ink cartridge IC is installed in the mounting portion 12, the tilting portion TP tilts upward in the vertical direction as it gets closer to the cover 13. The mounting portion 12 has a first guide portion GD3 that guides the tilting portion TP, and the cover 13 has a third limiting portion LM3. When the mounting portion 12 is in the open state, the third limiting portion LM3 is located further away from the ink cartridge IC than the second limiting portion LM2. When the mounting portion 12 is in the closed state, the third limiting portion LM3 protrudes toward the operation portion CL, restricting the movement of the ink cartridge IC.

[0072] Alternatively, in the printing apparatus 1, the following configuration may be adopted: the ink cartridge IC is rotatable between a restricted position and a released position, wherein in the restricted position, the movement of the ink cartridge IC along the removal direction is restricted by the first restricting part LM1, and in the released position, the restriction of the first restricting part LM1 is released, and the tilting part TP contacts the first guiding part GD3.

[0073] Alternatively, in the printing apparatus 1, the following configuration may be adopted: when the ink cartridge IC rotates from the restricted position to the released position, the connecting part CN1 contacts the lower part of the connected part CN2.

[0074] Alternatively, in the printing apparatus 1, the following configuration may be adopted: when the mounting section 12 is in the closed state, the second limiting section LM2 is located between the tilting section TP and the first guiding section GD3.

[0075] Alternatively, in the printing apparatus 1, the following configuration may be adopted: by rotating the ink cartridge IC relative to the connection position where the connecting part CN1 is connected to the connected part CN2, the restriction of the second limiting part LM2 is released.

[0076] Alternatively, in the printing apparatus 1, the following configuration may be adopted: in response to operating the operation unit CL in a direction that is more downward than the removal direction in the removal direction, the restriction of the first restriction unit LM1 is released.

[0077] Alternatively, in the printing apparatus 1, the following configuration may be adopted: the length L1 of the area where the connecting part CN1 and the connected part CN2 overlap in the removal direction is longer than the length L2 that the ink cartridge IC, in the state of being mounted on the mounting part 12, can move in the removal direction before being restricted by the second restricting part LM2 during the removal process.

[0078] Alternatively, in the printing apparatus 1, the following configuration may be adopted: by moving the ink cartridge IC in a direction different from the removal direction, the restriction of the second restriction part LM2 is released.

[0079] Alternatively, the printing apparatus 1 may be configured such that the second limiting part LM2 is a component capable of switching between an upright state and a folded state. When the state of the mounting part 12 is switched from the closed state to the open state by the cover 13, the second limiting part LM2 switches from the folded state to the upright state. When the state of the mounting part 12 is switched from the open state to the closed state by the cover 13, the second limiting part LM2 switches from the upright state to the folded state.

[0080] Alternatively, in the printing apparatus 1, the following configuration may be adopted: the ink cartridge IC is equipped with an opening valve VL, which switches between an open state (opening the connection between the inside and outside of the liquid storage section TK) and a closed state (cutting off the connection between the inside and outside of the liquid storage section TK) when the ink cartridge IC is in the open state. When the ink cartridge IC is in the open state, the pressure inside the liquid storage section TK is atmospheric pressure. The opening valve VL switches the state of the ink cartridge IC from the open state to the closed state before being restricted by the second restricting part LM2 during the removal process.

[0081] Alternatively, in the printing apparatus 1, the following configuration may be adopted: the opening valve VL overlaps with the first restricting part LM1 in the width direction, which is orthogonal to both the removal direction and the vertical direction.

[0082] It should be noted that the items described above can also be combined in any way.

[0083] For example, although the first limiting part LM1 in this embodiment is provided on the upper part of the ink cartridge IC, it can also be provided on other parts of the ink cartridge IC instead. Similarly, the position of the setting operation part CL can also be changed appropriately.

[0084] Furthermore, this embodiment can also be applied to printing apparatuses capable of mounting ink cartridges with shapes and configurations different from those of ink cartridge ICs. That is, the printing apparatus 1 may include: a printing section for printing on a printing medium; a mounting section for attaching and detaching a liquid container having a liquid storage section, the liquid container storing liquid supplied to the printing section; and a cover for switching the state of the mounting section between an open state and a closed state, wherein the mounting section or the liquid container has a force-applying member that applies force to the liquid container in a first direction orthogonal to the vertical direction from the mounting section toward the cover, and the liquid container includes: a first limiting section for limiting the removal of the liquid container from the mounting section; and an operating section for... When the liquid container is installed on the mounting portion, it is located closer to the cover than the first limiting portion, and receives the operation of releasing the restriction of the first limiting portion. The cover has a second limiting portion that restricts the movement of the liquid container in the first direction during the removal of the liquid container installed on the mounting portion from the mounting portion in the first direction. The liquid container has a connecting portion that is connected to a connected portion provided on the mounting portion. The connecting portion supplies the liquid. When the movement of the liquid container in the first direction is restricted by the second limiting portion, the connecting portion remains connected to the connected portion.

[0085] As explained above, the printing apparatus according to the embodiment includes: a printing unit for printing on a printing medium; a mounting unit for attaching and detaching a liquid container having a liquid storage unit, the liquid container storing liquid supplied to the printing unit; and a cover for switching the state of the mounting unit between an open state and a closed state. The mounting unit or the liquid container includes a force-applying member that applies force to the liquid container in a first direction orthogonal to the vertical direction from the mounting unit toward the cover. The liquid container includes a first limiting portion disposed on the upper part of the liquid container in the vertical direction, limiting the removal of the liquid container from the mounting unit. The printing apparatus includes a liquid container and an operating unit, which is located on the upper part of the liquid container in the vertical direction. When the liquid container is installed on the mounting part, the operating unit is positioned closer to the cover than the first limiting part, and receives the operation to release the first limiting part. The cover has a second limiting part that restricts the movement of the liquid container in the first direction during removal of the liquid container installed on the mounting part from the mounting part. The liquid container has a connecting part connected to a connected part provided on the mounting part. The connecting part supplies liquid, and when the movement of the liquid container in the first direction is restricted by the second limiting part, the connecting part remains connected to the connected part. Thus, the printing apparatus can prevent liquid leakage between the connecting part and the connected part when the liquid container is removed from the mounting part.
