Definitions

  • the present invention relates to an image recording apparatus, in which liquid is supplied from a liquid cartridge to a recording head mounted to a carriage via a tube.
  • an ink-jet image recording apparatus which records an image on a recording medium such as a sheet of paper by ejecting ink onto the recording medium based on an input signal. More specifically, the ink-jet image recording apparatus has a recording head and the recording head ejects ink from its nozzles onto a recording medium, such that an image is formed on the recording medium.
  • One type of known recording heads is mounted to a carriage and reciprocates together with the carriage in a predetermined direction relative to the recording medium.
  • Driving force is transmitted to the carriage from a drive source such as a motor, and upon receiving the driving force the carriage reciprocates in the predetermined direction guided by a guide shaft or a guide rail. While the carriage is reciprocating, the recording head selectively ejects ink droplets onto the recording medium, and the ink droplets' landing on the recording medium forms an image on the recording medium.
  • a flexible tube is provided between the ink cartridge and the recording head, as described in Patent Application Publication Nos. JP 2002-264363 , JP 2001-199084 , or JP 2010-30143 . Because the tube is flexible, the tube flexes and stretches, following the reciprocal movement of the carriage. When the carriage is in a position closest to the ink cartridge, the tube is flexed, such that the tube extends, making a U-turn. When the cartridge is in a position farthest from the ink cartridge, the tube stretches, such that the tube extends, curving gently.
  • the nozzle surface of the recording head is configured to be covered by a cap because the nozzle surface may dry out if not covered by a cap or ink may leak from the nozzles. Nevertheless, when the image recording apparatus is powered off during the image recording operation, the carriage may stop and may not reach a position in which the recording head is supposed to be covered by the cap. Therefore there may be a situation in which the recording head is not capped.
  • the image recording apparatus When the image recording apparatus is transported or packed for repair purpose or other purposes while the recording head is not capped, the image recording apparatus may be oriented differently from when the image recording apparatus is in use. For example, when packed, the rear face of a thin flat body of the image recording apparatus may be oriented downwardly in order to reduce the foot print of the package. When this occurs, the liquid surface in the ink cartridge is positioned higher than the recording head, and all the ink stored in the ink cartridge may leak from the recording head. The same problem may arise when the left or right face of the body is oriented downwardly or when the body is placed upside down. The problem is significant when ink flow is not blocked by a valve or the like in an ink path extending from the ink cartridge, which is in communication with the atmosphere, to the recording head.
  • EP 2208618 discloses an image recording apparatus comprising a cartridge a recording head, a conveying mechanism, a cartridge and a tube connecting the recording head and a mounting portion.
  • a technical advantage of the present invention is that the likelihood may be reduced that all the liquid stored in a liquid cartridge leaks from the nozzles of a recording head when the position of an image recording apparatus is changed.
  • an image recording apparatus according to claim 1 is provided.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a front portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a right portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a lower portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.
  • an image recording apparatus according to claim 5 is provided.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a front portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a left portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.
  • the liquid cartridge is positioned above the recording head.
  • the connection opening is positioned at an upper portion of the liquid chamber because the connection opening is formed at a lower portion of the liquid chamber when the image recording apparatus is in use. Therefore, the liquid surface in the liquid chamber is positioned below the connection opening, and liquid may not flow out of the liquid chamber to the liquid path. Thus, the likelihood may be reduced that all the liquid stored in the liquid cartridge leaks from the nozzles of the recording head.

  • the atmosphere communication opening 93 may be connected to a labyrinth-like path provided further outside than the atmosphere communication opening 93, such that it may be more difficult for ink to flow out of the atmosphere communication opening 93 to the outside of the ink cartridge 32.
  • an ink-absorbing member may be provided in the cartridge mounting portion 110 at a position corresponding to the atmosphere communication opening 93, so that the ink-absorbing member can absorb ink leaking out of the atmosphere communication opening 93.
  • the nozzles of the recording head 39 are positioned above the ink surface (gas-liquid interface) in the ink chamber 80. Because the ink surface in the ink chamber 80 may not exceed the height of the atmosphere communication opening 93, it may be sufficient if the nozzles of the recording head 39 are positioned above the atmosphere communication opening 93.
  • the atmosphere communication opening 93 corresponds to an atmosphere communication portion.
  • the ink path 89 is formed in the main body 81 below the ink chamber 80.
  • the ink path 89 corresponds to a liquid path.
  • the ink path 89 is a path connecting the ink supply portion 88 and the ink chamber 80, such that ink can flow between the ink supply portion 88 and the ink chamber 80.
  • the left wall 86 is removed.
  • the ink path 89 is connected to the ink chamber 80 via a connection opening 92.
  • the connection opening 92 is formed at the lowest portion of the bottom surface 91 of the ink chamber 80 with respect to the up-and-down direction 102. Therefore, the bottom surface 91 does not have to a horizontal surface, but may be an inclined surface or curved surface which goes down toward the connection opening 92.
  • connection opening 92 is positioned at a front portion of the ink chamber 80 with respect to the front-and-rear direction 103 and at a right portion of the ink chamber 80 with respect to the left-and-right direction 101.
  • the connection opening 92 is positioned at a front end of the ink chamber 80 with respect to the front-and-rear direction 103 and at a right end of the ink chamber 80 with respect to the left-and-right direction 101. That is, the connection opening 92 is defined by the inner surface of the front wall 82 and the inner surface of the right wall 87.
  • the ink supply opening 90 is positioned at the center of the main body 81 with respect to the left-and-right direction 101.
  • the connection opening 92 is offset to the right of the ink supply opening 90 with respect to the left-and-right direction 101
  • connection opening 92 is not limited to a specific shape, but may be rectangular as shown in Fig. 5 , or circular or polygonal.
  • the size of the connection opening 92 is adjusted according to an initial amount of ink stored in the ink chamber 80. More specifically, the size of the connection opening 92 is chosen in order for the ink surface in the ink chamber 80 to be positioned below the connection opening 92 even when the ink cartridge 32 is oriented, such that the rear wall 83, the upper wall 84, or the left wall 86 faces downward, as described below.
  • the ink path 89 is a space defined by a portioning wall 94 having the bottom surface 91 of the ink chamber 80, an L-shaped partitioning wall 95 facing the rear wall 83 and the right wall 87, the front wall 82, the rear wall 83, the lower wall 85, and the right wall 87.
  • the partitioning wall 94 is spaced apart from the lower wall 85 in the up-and-down direction 102, and faces the lower wall 85.
  • the partitioning wall 94 is connected to the front wall 82, the rear wall 83, the right wall 86, and the left wall 87.
  • the partitioning wall 95 is spaced apart from the rear wall 83 forward in the front-and-rear direction 103, and faces the rear wall 83.
  • the partitioning wall 95 also is spaced apart from the right wall 87 to the left in the left-and-right direction 101, and faces the right wall 87.
  • the partitioning wall 95 is connected to the left wall 86, the front wall 82, the lower wall 85, and the partitioning wall 94.
  • the ink path 89 extends from a corner formed between the front wall 82 and the right wall 87 toward the rear wall 83 along the right wall 87 in the front-and-rear direction 103 and reaches a corner formed between the rear wall 83 and the right wall 87.
  • the ink path 89 then extends from the corner formed between the rear wall 83 and the right wall 87 toward the left wall 86 along the rear wall 83 in the left-and-right direction 101.
  • the ink path 89 has an L shape extending along the right wall 87 and the rear wall 83.
  • the ink path 89 is connected to the inner space of the ink supply portion 88 at the rear wall 83.
  • the ink path 89 has a cross-section taken along the left-and-right direction 101 and the up-and-down direction 102, and the cross-section has a width W1 in the left-and-right direction 101.
  • the ink chamber 80 has a cross-section taken along the left-and-right direction 101 and the up-and-down direction 102, and the cross-section has a width W2 in the left-and-right direction 101.
  • the width W1 of the ink path 89 is less than the width W2 of the ink chamber 80 (W1 ⁇ W2).
  • the ink path 89 has a volume V1 and the ink chamber has a volume V2, and the volume V1 of the ink path 89 is less than the volume V2 of the ink chamber 80 (V1 ⁇ V2).
  • the ink cartridge 32 may comprise a remaining-ink-amount detection portion provided at the main body 81 for the multi-function apparatus 10 to determine a remaining amount of ink in the ink chamber 80. Nevertheless, such a remaining-ink-amount detection portion or the like may not directly be related to the present invention, and therefore the detailed description of the remaining-ink-amount detection portion or the like is omitted here.
  • the ink supply portion 88 may comprise a valve provided in the inner space of the ink supply portion 88, and the valve may close the ink supply opening 90.
  • the ink needle 122 pushes and moves the valve, such that the ink supply opening 90 is opened and ink flows out of the ink chamber 80 into the ink needle 122 via the ink path 89.
  • the ink supply portion 88 may comprise an elastic film such as rubber provided in the inner space of the ink supply portion 88, and the elastic film may close the ink supply opening 90.
  • the ink needle 122 penetrates through the elastic film, such that the ink supply opening 90 is opened and ink flows out of the ink chamber 80 into the ink needle 122 via the ink path 89.
  • the atmospheric air can enter the ink chamber 90 via the atmosphere communication opening 93.
  • the carriage 38 When the multi-function apparatus 10 does not perform image recording, the carriage 38 is moved to a home position on the right side of the multi-function apparatus 10 with respect to the left-and-right direction 101 (the right side in Fig. 3 ), and the nozzle surface of the recording head 39 is covered by a cap (not shown) because the nozzle surface may dry out if not covered by the cap or ink may leak from the nozzles. Nevertheless, when the multi-function apparatus 10 is powered off during the image recording operation, the carriage 38 may stop and may not reach the home position. Therefore, there may be a situation in which the recording head 39 is not capped.
  • the multi-function apparatus 10 When the multi-function apparatus 10 is in use, the multi-function apparatus 10 take the position as shown in Fig 1 , and the nozzle surface of the recording head 39 is positioned above the ink surface in the ink chamber 80 of the ink cartridge 32 mounted to the cartridge mounting portion 110. Therefore, negative pressure is generated at the nozzles of the recording head 39, such that ink in the nozzles is pulled toward the ink-cartridge 32 side.
  • the multi-function apparatus 10 When the multi-function apparatus 10 is packed for repair purpose or other purposes while the recording head 39 is not capped, the multi-function apparatus 10 may be oriented differently from when the multi-function apparatus 10 is in use. For example, when packed, the rear face of the thin flat body of the multi-function apparatus 10 may be oriented downwardly in order to reduce the foot print of the package. In other words, the rear face of the multi-function apparatus 10 may be positioned below the front face of the multi-function apparatus 10. When this occurs, the ink surface in the ink chamber 80 of the ink cartridge 23 mounted to the cartridge mounting portion 110 is positioned above the nozzle surface of the recording head 39 with respect to the gravitational direction, and the negative pressure is not generated at the nozzles of the recording head 39 any more.
  • the ink chamber 80 when the ink chamber 80 has an initial amount of ink therein, the ink chamber 80 has an ink surface 96.
  • the rear wall 83 of the ink cartridge 32 mounted to the cartridge mounting portion 110 is positioned below the front wall 82 of the ink cartridge 32 mounted to the cartridge mounting portion 110 as shown in Fig. 8 .
  • connection opening 92 connecting the ink chamber 80 and the ink path 89 is positioned at the uppermost position in the ink chamber 80, and therefore, the ink surface 96 is positioned below the connection opening 92. Accordingly, ink does not flow out of the ink chamber 80 into the ink path 89 when the multi-function apparatus 10 is oriented like this.
  • the left wall 86 of the ink cartridge 32 mounted to the cartridge mounting portion 110 is positioned below the right wall 87 of the ink cartridge 32 mounted to the cartridge mounting portion 110 as shown in Fig. 9 .
  • the connection opening 92 connecting the ink chamber 80 and the ink path 89 is positioned at the uppermost position in the ink chamber 80, and therefore the ink surface 96 is positioned below the connection opening 92. Accordingly, ink does not flow out of the ink chamber 80 into the ink path 89 when the multi-function apparatus 10 is oriented like this.
  • the upper wall 84 of the ink cartridge 32 mounted to the cartridge mounting portion 110 is positioned below the lower wall 85 of the ink cartridge 32 mounted to the cartridge mounting portion 110 as shown in Fig. 10 .
  • the connection opening 92 connecting the ink chamber 80 and the ink path 89 is positioned at the uppermost position in the ink chamber 80 and therefore the ink surface 96 is positioned below the connection opening 92. Accordingly ink does not flow out of the ink chamber 80 in to the ink path 89 when the multi-function apparatus 10 is oriented like this.
  • the ink cartridge 32 When the multi-function apparatus 10 is oriented, such that the right face of the multi-function apparatus 10 faces downward, i.e., when the right face of the multi-function apparatus 10 is positioned below the left face of the multi-function apparatus 10, the ink cartridge 32 is positioned below the nozzle surface of the recording head 39 in most cases. Therefore, negative pressure is generated in the nozzles of the recording head 39, such that ink is pulled toward the ink-cartridge 32 side. Accordingly, there is little likelihood that ink leaks from the nozzles of the recording head 39.
  • the ink cartridge 32 When the multi-function apparatus 10 is oriented, such that the front face of the multi-function apparatus 10 faces downward, i.e., when the front face of the multi-function apparatus 10 is positioned below the rear face of the multi-function apparatus 10, the ink cartridge 32 is positioned below the nozzle surface of the recording head 39. Therefore, negative pressure is generated in the nozzles of the recording head 39, such that ink is pulled toward the ink-cartridge 32 side. Accordingly, there is little likelihood that ink leaks from the nozzles of the recording head 39.
  • connection opening 92 connecting the ink chamber 80 and the ink path 89 is positioned at a lower portion of the ink chamber 80 with respect to the up-and-down direction 102, at a front portion of the ink chamber 80 with respect to the front-and-rear direction 103, and at a right portion of the ink chamber 80 with respect to the left-and-right direction 101, even if the multi-function apparatus 10 is oriented differently from when the multi-function apparatus 10 is in use, the likelihood may be reduced that all the ink stored in the ink chamber 80 leaks from the nozzles of the recording head 39.
  • connection opening 92 is positioned at the front end of the ink chamber 80 with respect to the front-and-rear direction 103 and at the right end of the ink chamber 80 with respect to the left-and-right direction 101, the ink chamber 80 can store a relatively large amount of ink therein as an initial amount.
  • connection opening 92 is not positioned at the front end of the ink chamber 80 with respect to the front-and-rear direction 103 and at the right end of the ink chamber 80 with respect to the left-and-right direction 101, the above described advantage can be achieved as long as the connection opening 92 is positioned at a front portion of the ink chamber 80 with respect to the front-and-rear direction 103, and at a right portion of the ink chamber 80 with respect to the left-and-right direction 101 and the amount of ink stored in the ink chamber 80 is chosen appropriately.
  • the volume V1 of the ink path 89 is less than the volume V2 of the ink chamber 80, even if ink in the ink path 89 flows out, the amount of ink flowing out of the ink cartridge 32 is small.
  • the width W1 of the ink path 89 in the left-and-right direction 101 is less than the width W2 of the ink chamber 80 in the left-and-right direction 101, the flow resistance of the ink path 89 is greater than the flow resistance of the ink chamber 80. It is more difficult for ink to flow in the ink path 89.
  • the ink supply opening 90 is positioned at a lower portion of the rear wall 83, when the upper wall 84 is positioned below the lower wall 85, not all the ink in the ink path 89 flows out.
  • connection opening 92 is offset to the right of the ink supply opening 90 with respect to the left-and-right direction 101, i.e., the ink supply opening 90 is positioned to the left of the connection opening 92 with respect to the left-and-right direction 101, when the multi-function apparatus 10 is oriented, such that the right face of the multi-function apparatus 10 faces downward after ink stored in the ink chamber 80 has been consumed to some extent, the ink surface in the ink chamber 80 is positioned below the ink supply opening 90.
  • connection opening 92 is positioned at the lowest portion of the bottom surface 91 of the ink chamber 80 with respect to the up-and-down direction 102, almost all the ink in the ink chamber 80 flows out of the ink chamber 80 when the multi-function apparatus 10 is in use.
  • the ink chamber 80 is positioned above the ink supply opening 90 with the bottom surface 91 positioned between the ink chamber 80 and the ink supply opening 90 with respect to the up-and-down direction 102, and therefore almost all the ink in the ink chamber 80 flow out via the ink supply opening 90.
  • the ink cartridge 32 has a mirror image of the ink cartridge 32 of the above-described embodiment (the ink cartridge 32 of Fig. 5 ) relative to a plane extending along the up-and-down direction 102 and the front-and-rear direction 103.
  • the cartridge mounting portion 110 is positioned further forward than the nozzles of the recording head 39 with respect to the front-and-rear direction 103 and positioned to the right of the paper conveying path 23 with respect to the left-and-right direction 101, and the ink cartridge 32 mounted to the cartridge mounting portion 110 comprises the connection opening 92 positioned at a lower portion of the ink chamber 80 with respect to the up-and-down direction 102, at a front portion of the ink chamber 80 with respect to the front-and-rear direction 103, and at a right portion of the ink chamber 80 with respect to the left-and-right direction 101.
  • the cartridge mounting portion 110 is positioned further forward than the nozzles of the recording head 39 with respect to the front-and-rear direction 103 and positioned to the left of the paper conveying path 23 with respect to the left-and-right direction 101, and the ink cartridge 32 mounted to the cartridge mounting portion 110 comprises the connection opening 92 positioned at a lower portion of the ink chamber 80 with respect to the up-and-down direction 102, at a front portion (preferably at the front end) of the ink chamber 80 with respect to the front-and-rear direction 103, and at a left portion (preferably at the left end) of the ink chamber 80 with respect to the left-and-right direction 101 as shown in Fig. 11 .
