Definitions

  • the cover includes an abutment portion.
  • the abutment portion is configured to abut on the rear surface of the liquid cartridge to move the liquid cartridge in the second posture in the first direction until the liquid cartridge reaches a position where the first portion is capable of abutting on the protrusion.
  • the case 101 which constitutes a wall of the cartridge attaching unit 110, has a box-like shape that has a top surface that defines a top part of an internal space of the case 101, a bottom surface that defines a bottom part of the internal space, an end surface connecting the top part and the bottom part together, and the opening 112.
  • the opening 112 is positioned to confront the end surface in the insertion direction 51 and removal direction 52, and the opening112 can be exposed to a user interface surface of the printer 10.
  • the interface surface is the surface which the user confronts when using the printer 10.
  • the ink cartridge 30 is inserted into and removed from the case 101 through the opening 112.
  • Guide grooves 109 are formed at the top surface and bottom surface.
  • the cover 108 is pivotally movable about a pivot axis 115.
  • the pivot axis 115 extends in parallel with a mounting surface on which the printer 10 is mounted, that is, the pivot axis 115 extends in a horizontal direction. In the present embodiment, the pivot axis 115 extends in the rightward direction 55 and the leftward direction 56.
  • the cover 108 has an outer shape in conformance with a size of the opening 22. More specifically, the outer shape of the cover 108 is generally rectangular capable of covering the opening 22.
  • the cover 108 has a closed posture closing the opening 22 of the casing 14. As illustrated in Fig. 8 , the ink cartridge 30 cannot be removed from and inserted into the cartridge attaching unit 110 when the cover 108 is at its closed posture.
  • the engagement portion 123 is tapered toward its tip as viewed in the leftward direction 56 or the rightward direction 55.
  • the engagement portion 123 includes a distal end face 120 and a guide surface 124.
  • the distal end face 120 is positioned farther from the pivot axis 115 than the guide surface 124 to the pivot axis 115, that is, the distal end face 120 is positioned above the guide surface 124 at the closed posture of the cover 108.
  • the distal end face 120 expands in the downward direction 53 and the upward direction 54 when the cover 108 is at its closed posture. In the other words, the distal end face 120 has a dimension in the downward direction 53 and the upward direction 54 when the cover 108 is at its closed posture.
  • the ink cartridge 30 illustrated in Figs. 3 through 6 is a vessel in which ink is retained.
  • a space formed in the ink cartridge 30 is the retaining chamber 36 (an example of a liquid retaining chamber).
  • the retaining chamber 36 is defined by an internal frame 35 accommodated in a rear cover 31 and a front cover 32, those forming an outer shape of the ink cartridge 30.
  • the retaining chamber 36 can be defined by the rear cover 31 and the front cover 32.
  • a guide surface 89 extends from the manipulation surface 92 and is positioned backward of the manipulation surface 92 in the backward direction 58.
  • the guide surface 89 faces in the backward direction 58 and the upward direction 54.
  • the guide surface 89 is a surface accessible to the engagement portion 123 of the protrusion 121 of the cover 108 in the insertion direction 51.
  • the front cover 32 is box shaped having side surfaces 143 and 144, the upper surface 141, and the lower surface 142.
  • the side surfaces 143 and 144 are spaced away from each other in the rightward direction 55 and the leftward direction 56 and extend from the front surface 140 in the backward direction 58.
  • the upper surface 141 and lower surface 142 are spaced away from each other in the downward direction 53 and the upward direction 54 and extend from the front surface 140 in the backward direction 58.
  • the front cover 32 has an open end opening backward in the backward direction 58.
  • the internal frame 35 is inserted into the front cover 32 through the open end. That is, the front cover 32 covers a front portion of the internal frame 35 which is not covered by the rear cover 31.
  • the upper surface 141 of the front cover 32 forms the upper surface of the ink cartridge 30 together with the upper surface 39 of the rear cover 31, and the lower surface 142 of the front cover 32 forms the lower surface of the ink cartridge 30 together with the lower surface 42 of the rear cover 31.
  • the ink supply opening 71 is closed and opened by the valve body 77.
  • the coil spring 78 is adapted to bias the valve body 77 in the forward direction 57. Therefore, the valve body 77 closes the ink supply opening 71 of the sealing member 76 in a state where no external force is applied.
  • the detection member 59 has a float 63 whose specific gravity is lower than that of the ink retained in the retaining chamber 36. Therefore, the float 63 generates buoyancy while the float 63 is in the ink in the retaining chamber 36.
  • the detection member 59 is pivotally moved in the counterclockwise direction in Fig. 6 because of the buoyancy of the float 63.
  • a portion of the detection member 59 is entered the interior of the detection portion 62, and is in contact with a wall defining a forward end of the detection portion 62 in the forward direction 57. Consequently, the pivot posture of the detection member 59 can be maintained.
  • the detection member 59 shuts off the light emitted from the sensor 103, and performs other processing on the light, the light being configured to advance through the detection portion 62 in the rightward direction 55 or the leftward direction 56.
  • the cap 79 in the ink supply portion 34 starts to enter the cylindrical guide 105. Further, the recess 96 of the front cover 32 faces the rod 125, and the rod 125 starts to enter the recess 96.
  • the abutment portion 126 is brought into abutment with the lower portion 41L of the rear surface 41 of the ink cartridge 30 that is in the unlocked state by the pivotal movement of the cover 108 from its open posture toward its closed posture.
  • the ink cartridge 30 is pushed in the insertion direction 51 by the abutment portion 126 as illustrated in Fig. 16 , so that the unlocked ink cartridge 30 is moved in the insertion direction 51 to a position where the manipulation portions 90 can abut on the protrusions 121.
  • the ink supply apparatus 100 is capable of enabling the user to recognize the unlocked state of the ink cartridge 30 relative to the cartridge attaching unit 110 through opening and closing operation of the cover 108, and also is capable of preventing the ink cartridge 30 from being released or unlocked relative to the cartridge attaching unit 110 from the locked state of the ink cartridge 30 in a state where the cover 108 is closed.
