The peripheral wall 86 is provided on the opposite side of the second wall 72 from the concave portion 65 side, that is, on the outer side of the second wall 72. Further, the peripheral wall 86 protrudes from the second wall 72 toward the side opposite to the third wall 73 side (the −Z axis direction side). The second wall 72 is provided with a communication hole 85 </ b> A that allows the accommodating portion 109 and the supply port 85 to communicate with each other. The ink stored in the storage unit 109 is sent to the supply port 85 through the communication hole 85A.

  Further, as shown in FIG. 5, the supply port 85 includes a leaf spring 131, a foam 133, and a filter 135. As shown in FIG. 8, the first case 62 is provided with a recess 137 in a region surrounded by the peripheral wall 86. The leaf spring 131 and the foam 133 are accommodated in the recess 137 as shown in FIG. The filter 135 is provided in a region surrounded by the peripheral wall 86 and covers the recess 137 from the outside of the second wall 72. As the filter 135, for example, a film material having a through-hole formed by pressing or the like, an asymmetric membrane such as an MMM membrane manufactured by PALL, for example, a symmetric membrane such as a woven fabric, or the like can be employed. The foam 133 and the filter 135 are each a porous member. The supply port 85 is provided with a plurality of members. In the manufacturing method of the cartridge 7 to be described later, among these members, the entire surface of the filter 135 which is a porous member located at the most distal end side of the supply port 85 is wetted with ink after the ink filling is completed. Ink is filled.

  A protrusion 87 is provided on the fourth wall 74. The protrusion 87 protrudes from the fourth wall 74 toward the opposite side (+ X-axis direction side) to the fifth wall 75 side. The protrusion 87 is located between the second wall 72 and the third wall 73 in the Z-axis direction. The protrusion 87 is fitted into the engagement hole 37 shown in FIG. 3 in a state where the cartridge 7 is mounted on the holder 25. In addition, as shown in FIG. 7B, the fifth wall 75 is provided with a protrusion 88. The protruding portion 88 protrudes from the fifth wall 75 toward the side opposite to the fourth wall 74 side (−X axis direction side). The protrusion 88 is locked by the lever 35 shown in FIG. 3 in a state where the cartridge 7 is mounted on the holder 25. Thereby, the cartridge 7 can be fixed to the holder 25. In the second wall 72, a communication hole 91 is provided in a region surrounded by the peripheral wall 86 and in a region outside the filter 135 of the supply port 85. The communication hole 91 passes between the inside of the recess 65 and the outside of the first case 62.

  As shown in FIG. 5, the cartridge 7 includes a valve unit 101, a coil spring 103, a pressure receiving plate 105 as a pressure receiving portion, and a sheet member 107 as a flexible portion. The sheet member 107 is formed of a synthetic resin (for example, nylon or polypropylene) and has flexibility. The sheet member 107 is provided on the first case 62 side of the second case 63. The sheet member 107 is bonded to the sheet bonding portion 81 of the first case 62. In the present embodiment, the sheet member 107 is bonded to the sheet bonding portion 81 by welding. Thereby, the recess 65 of the first case 62 is closed by the sheet member 107. A region surrounded by the recess 65 and the sheet member 107 is referred to as a housing portion 109. Then, the ink is stored in the concave portion 65 blocked by the sheet member 107, that is, in the storage portion 109. For this reason, in this embodiment, the sheet member 107 constitutes a part of the wall of the accommodating portion 109.

  As described above, in the first case 62, as shown in FIG. 6, the recess 65 is partitioned by the partition wall 83 into the first recess 65A and the second recess 65B. For this reason, when the sheet member 107 is joined to the sheet joining portion 81, the accommodation portion 109 is partitioned into the first accommodation portion 109A and the second accommodation portion 109B. 109 A of 1st accommodating parts respond | correspond to 65 A of 1st recessed parts. The second accommodating portion 109B corresponds to the second recess 65B. As described above, the sheet member 107 has flexibility. For this reason, the volume of 109 A of 1st accommodating parts can be changed. The sheet member 107 is joined to the first case 62 in a state where the sheet member 107 is stretched in advance along the inner surface 67 of the concave portion 65 so as to easily follow the change in the volume of the first accommodating portion 109A.

  As shown in FIG. 5, the coil spring 103 is provided on the first case 62 side of the sheet member 107 and is accommodated in the recess 65. The coil spring 103 is wound in a truncated cone shape. In FIG. 5, the coil spring 103 is simplified. The pressure receiving plate 105 is provided on the sheet member 107 side of the coil spring 103. That is, the pressure receiving plate 105 is interposed between the coil spring 103 and the sheet member 107. The pressure receiving plate 105 faces the second case 63 and is in contact with the sheet member 107. A lower bottom portion of the coil spring 103 is in contact with the first wall 71. The upper bottom portion of the coil spring 103 is in contact with the surface of the pressure receiving plate 105 opposite to the surface on the sheet member 107 side. Further, the upper bottom portion of the coil spring 103 is in contact with the substantially central portion of the pressure receiving plate 105. The pressure receiving plate 105 is made of a synthetic resin such as polypropylene or a metal such as stainless steel. Since the pressure receiving plate 105 and the portion of the sheet member 107 that is in contact with the pressure receiving plate 105 are members that directly or indirectly receive pressure from the coil spring 103, they can be collectively regarded as a “pressure receiving portion”. Is possible.

  The coil spring 103 biases the pressure receiving plate 105 toward the sheet member 107 side (second case 63 side). In other words, the coil spring 103 biases the pressure receiving plate 105 in the negative Y-axis direction. That is, the coil spring 103 has a function as a biasing member that biases the pressure receiving plate 105 in a direction in which the volume of the accommodating portion 109 is increased. The second case 63 is provided on the opposite side of the sheet member 107 from the pressure receiving plate 105 side. The second case 63 is attached to the first case 62 so as to cover the sheet member 107. Thereby, the sheet member 107 is protected from the outside.

  The valve unit 101 is provided inside the recess 65. The sheet member 107 covers the recess 65 together with the valve unit 101. A vent hole 111 is formed in a portion of the seat member 107 that overlaps the valve unit 101. The second case 63 is provided with an air communication hole 113. The space between the sheet member 107 and the second case 63 communicates with the outside of the cartridge 7 through the air communication hole 113. For this reason, air is interposed in the space between the sheet member 107 and the second case 63.

  The space between the sheet member 107 and the second case 63 is called an atmospheric chamber 115. The atmosphere communication hole 113 communicates with the atmosphere chamber 115. In the present embodiment, the communication hole 91 communicates with the atmospheric chamber 115. That is, in this embodiment, the space surrounded by the peripheral wall 86 communicates from the communication hole 91 to the atmosphere communication hole 113 through the atmosphere chamber 115.

  Further, as shown in FIG. 5, the cartridge 7 includes a prism unit 121 and a sheet member 123. Here, as shown in FIG. 8, an opening 125 is provided in the second wall 72 of the first case 62. The opening 125 is closed from the outside of the first case 62 by the prism unit 121. As shown in FIG. 9, the prism unit 121 includes a prism 122 that protrudes from the outside of the first case 62 to the inside of the first case 62 through the opening 125.

  The prism 122 functions as a detection unit for optically detecting ink. The prism 122 is a light-transmitting member made of a synthetic resin such as polypropylene. The members constituting the prism 122 may not be transparent as long as they have appropriate light transmittance. The ink in the storage unit 109 is detected as follows, for example. The printer 5 is provided with an optical sensor including a light emitting element and a light receiving element. Light is emitted from the light emitting element toward the prism 122. When ink is present around the prism 122, most of the light passes through the prism 122 and travels into the housing portion 109. On the other hand, when the ink is not present around the prism 122, most of the light emitted from the light emitting element is reflected by the two reflecting surfaces of the prism 122 and reaches the light receiving element. Based on whether light has reached the light receiving element, the printer 5 determines that there is little ink remaining in the storage unit 109 or that there is no ink in the storage unit 109. This determination is performed by the control unit 21 of the printer 5.

  Further, as shown in FIG. 8, a recess 126 is provided in the second wall 72 of the first case 62. The recess 126 is provided at a position between the supply port 85 and the prism 122 in the X-axis direction. The recess 126 is recessed from the outside of the second wall 72 toward the recess 65. The second wall 72 is provided with a communication hole 127 that communicates from the recess 126 to the recess 65, and a communication hole 128. The communication holes 127 and 128 are provided in the recess 65. The recess 126 is closed from the outside of the first case 62 by the sheet member 123.

  As shown in FIG. 9, the communication hole 127 communicates from the first recess 65 </ b> A to the recess 126. The communication hole 128 communicates from the recess 126 to the second recess 65B. That is, the first recess 65A and the second recess 65B communicate with each other through the communication hole 127, the recess 126, and the communication hole 128. For this reason, the first housing portion 109A and the second housing portion 109B communicate with each other through the communication hole 127, the recess 126, and the communication hole 128. FIG. 9 shows a cross section when the communication hole 127 and the communication hole 128 are cut along the XZ plane.

  As shown in FIG. 8, a circuit board 141 is provided on the opposite side of the sixth wall 76 to the recess 65 side, that is, on the outer side of the sixth wall 76. The circuit board 141 extends along the sixth wall 76. For this reason, the circuit board 141 is inclined with respect to each of the second wall 72 and the fifth wall 75. The circuit board 141 is inclined so as to approach the fourth wall 74 as it approaches the second wall 72 side from the third wall 73 side. A plurality of terminals 143 that are in contact with the contact mechanism 27 (FIG. 3) of the holder 25 are provided on the surface of the circuit board 141 opposite to the sixth wall 76 side. A storage device (not shown) such as a nonvolatile memory is provided on the sixth wall 76 side of the circuit board 141.

  In a state where the cartridge 7 is mounted on the holder 25, the plurality of terminals 143 are in electrical contact with the contact mechanism 27 shown in FIG. The contact mechanism 27 is electrically connected to the control unit 21 via the flexible cable 23 (FIG. 1). Then, the contact mechanism 27 and the storage device of the cartridge 7 are electrically connected via the circuit board 141, whereby various information can be transmitted between the control unit 21 and the storage device of the cartridge 7.

  As shown in FIG. 10, the position of the cartridge 7 having the above configuration is fixed by the lever 35 in a state where the cartridge 7 is mounted on the holder 25. When the cartridge 7 is mounted on the holder 25, the peripheral wall 86 comes into contact with the packing 57, and the protruding portion 53 is inserted into a region surrounded by the peripheral wall 86. That is, the peripheral wall 86 surrounds the flow path 51 from the outside of the protruding portion 53. Then, the filter 135 contacts the filter 55 in the region surrounded by the peripheral wall 86. As a result, the ink in the storage unit 109 can be supplied from the supply port 85 to the flow path 51 from the filter 55 via the form 133 and the filter 135.

  At this time, the peripheral wall 86 is in contact with the packing 57 in a state of surrounding the flow path 51 from the outside of the protruding portion 53. Thereby, the airtightness of the space enclosed by the surrounding wall 86 and the packing 57 is improved. For this reason, when ink is supplied from the cartridge 7 to the flow path 51, ink spilled outside the area surrounded by the protrusion 53 is blocked by the packing 57 and the peripheral wall 86.

  The flow of ink and the flow of air in the cartridge 7 in this embodiment will be described. In the cartridge 7, the ink 161 is accommodated in an accommodating portion 109 defined by the first case 62 and the sheet member 107 as shown in FIG. The accommodating portion 109 is partitioned by a partition wall 83 into a first accommodating portion 109A and a second accommodating portion 109B. Inside the case 61, a valve unit including a cover valve 163, a lever valve 165, and a spring member 167 is provided.

  The cover valve 163 is provided with an air introduction port 171. The air introduction port 171 passes through the cover valve 163. The air introduction port 171 functions as a communication path in the cartridge 7 for communicating the inside of the first housing portion 109 </ b> A and the air chamber 115 outside the housing portion 109. In other words, the air introduction port 171 serves as an inlet for introducing the air into the housing portion 109. The lever valve 165 is provided on the opposite side of the cover valve 163 from the second case 63 side. The lever valve 165 includes a valve part 173 and a lever part 175. The valve portion 173 overlaps with the air introduction port 171 of the cover valve 163. The lever portion 175 extends from the valve portion 173 into a region between the pressure receiving plate 105 and the inner surface 67 of the first wall 71. The spring member 167 is provided on the side opposite to the cover valve 163 side of the lever valve 165. The spring member 167 biases the valve portion 173 of the lever valve 165 toward the cover valve 163 side. Thereby, the air introduction port 171 of the cover valve 163 is blocked by the valve portion 173. Hereinafter, the state where the air introduction port 171 is blocked by the valve portion 173 is expressed as the air introduction port 171 being closed.

  As the ink 161 in the storage unit 109 is consumed, the pressure receiving plate 105 is displaced toward the inner surface 67 of the first wall 71 as shown in FIG. 11B, and the volume of the first storage unit 109A. Decrease. When the pressure receiving plate 105 is displaced toward the inner surface 67 side of the first wall 71, the pressure receiving plate 105 pushes the lever portion 175 toward the inner surface 67 side of the first wall 71. As a result, the posture of the valve portion 173 changes, and a gap is generated between the valve portion 173 and the cover valve 163. Thereby, the air introduction port 171 and the first housing portion 109A communicate with each other. In the following, a state in which the air introduction port 171 communicates with the accommodating portion 109 due to the occurrence of a gap between the valve portion 173 and the cover valve 163 is expressed as the air introduction port 171 being in an open state. When the air introduction port 171 is in the open state, the air in the air chamber 115 outside the accommodation unit 109 flows into the first accommodation unit 109A through the air introduction port 171.

  When the air passes through the air inlet 171 and flows into the first housing portion 109A, the pressure receiving plate 105 is displaced toward the second case 63 as shown in FIG. 11C. That is, the volume of the first housing portion 109A is increased as a result of the air flowing into the first housing portion 109A through the air inlet 171 as compared to the state shown in FIG. Thereby, the negative pressure in the accommodating part 109 reduces (approaches atmospheric pressure). When a certain amount of air is introduced into the first accommodating portion 109 </ b> A, the pressure receiving plate 105 is separated from the lever portion 175. Thereby, the valve part 173 closes the air introduction port 171. That is, the air introduction port 171 is closed. As described above, when the negative pressure in the storage unit 109 increases with the consumption of the ink 161 in the storage unit 109, the atmosphere introduction port 171 is temporarily opened, so that the pressure in the storage unit 109 is set to an appropriate pressure. It becomes possible to maintain the range.

  As described above, the cartridge 7 of the present embodiment is a semi-hermetic cartridge in which air is introduced from the air introduction port 171 into the housing portion 109 during use. As the ink in the storage unit 109 is consumed, the cartridge 7 decreases in volume as the storage unit 109 decreases and the negative pressure increases. When the negative pressure reaches a predetermined level, the valve unit 173 is moved to the atmosphere. The introduction port 171 is opened so that outside air is introduced into the accommodating portion 109, and then the valve portion 173 is configured to close the atmosphere introduction port 171.

  In the present embodiment, the communication hole 91 passes through the second wall 72 of the first case 62 from the region surrounded by the peripheral wall 86 and communicates with the atmospheric chamber 115. That is, the area surrounded by the peripheral wall 86 and the atmosphere chamber 115 communicate with each other through the communication hole 91. The atmospheric chamber 115 communicates with the atmospheric communication hole 113 through a gap between the second case 63 and the sheet member 107. Therefore, the area surrounded by the peripheral wall 86 passes through the case 61 and communicates with the outside of the case 61. Thereby, when the inside of the area surrounded by the peripheral wall 86 is sealed from the outside of the cartridge 7, the difference between the pressure in the area surrounded by the peripheral wall 86 and the pressure outside the case 61 (atmospheric pressure) is determined. Can be reduced.

  In the present embodiment, when the cartridge 7 is attached to the printer 5, the region surrounded by the peripheral wall 86 is sealed in the holder 25. Then, in a state where the region surrounded by the peripheral wall 86 is sealed, the filter 135 in the region surrounded by the peripheral wall 86 comes into contact with the filter 55 (FIG. 3) on the printer 5 side. As a result, it is possible to prevent the ink 161 from leaking out of the area surrounded by the peripheral wall 86. When the region surrounded by the peripheral wall 86 is sealed when the cartridge 7 is attached to the printer 5, the pressure in the region surrounded by the peripheral wall 86 may increase. At this time, due to an increase in pressure in the region surrounded by the peripheral wall 86, the air in the region surrounded by the peripheral wall 86 may flow into the housing portion 109 through the filter 135. When the air flows into the storage unit 109, it is conceivable that the air that flows in reaches the print head 19 of the printer 5 as bubbles. If air bubbles are mixed in the print head 19, the ejection performance of the ink 161 may deteriorate due to the air bubbles.

  In contrast, in this embodiment, the inside of the region surrounded by the peripheral wall 86 communicates with the outside of the first case 62 through the communication hole 91, the atmospheric chamber 115, and the atmospheric communication hole 113. . For this reason, when the region surrounded by the peripheral wall 86 is sealed when the cartridge 7 is attached to the printer 5, even if the pressure in the region surrounded by the peripheral wall 86 increases, the region surrounded by the peripheral wall 86 Can be released to the outside of the first case 62 via the communication hole 91, the atmospheric chamber 115, and the atmospheric communication hole 113. Further, for example, when the pressure in the space surrounded by the peripheral wall 86 rises due to the expansion of the air due to a temperature change, the air in the space surrounded by the peripheral wall 86 can be released to the outside of the cartridge 7. Thereby, the difference between the pressure in the region surrounded by the peripheral wall 86 and the pressure outside the first case 62 (atmospheric pressure) can be reduced. As a result, it is easy to maintain high ink ejection performance in the print head 19.

[Manufacturing method of cartridge]
A method for manufacturing the cartridge 7 will be described. In the present embodiment, a method of manufacturing the cartridge 7 (recycle cartridge) by reinjecting ink into the used cartridge after the ink is consumed and the remaining amount of ink becomes a predetermined value or less (refill processing) is mainly described. The explanation is as follows. The manufacturing method of the cartridge 7 of the present embodiment can also be used as a method of manufacturing the cartridge 7 (new cartridge) by injecting ink into the unused cartridge 7 before storing ink (initial filling).

  As shown in FIG. 12, the manufacturing method of the cartridge 7 in the present embodiment includes a preparation step S10 for preparing the cartridge 7, a discharge step S20 for discharging a substance in the storage unit 109, such as ink and air, and a storage unit. An injection process S30 for injecting ink into 109 and an information update process S40 are included.

  In the preparation step S10, a used cartridge is prepared in which ink is consumed and the remaining amount of ink becomes a predetermined value or less. Alternatively, an unused cartridge before containing ink is prepared.

The discharging step S20 is a step of discharging the substance in the accommodating portion 109 of the cartridge 7 prepared in the preparing step S10, such as ink and air. For example, in the case of a used cartridge, air and old ink often remain in the housing portion 109. If the discharging step S20 is performed in such a case, it is possible to reduce old ink and air mixed in the newly injected ink IK. Further, when a new cartridge is manufactured, the air in the storage unit 109 or dust or dust remaining in the storage unit 109 is discharged and then filled with the ink IK to be mixed into the ink IK. Air and impurities can be reduced. Therefore, it is possible to manufacture a cartridge with higher quality. The discharging step S20 can be omitted.
In the injection step S30, ink is injected into the storage unit 109. The discharge process S20 and the injection process S30 can be performed by various methods. Details of the discharging step S20 and the injecting step S30 will be described in detail later with reference to examples.
The information update step S40 is a step of rewriting information on the ink consumption amount of the memory provided on the circuit board 141 of the cartridge 7 to a usable value. When ink is used and the remaining amount of ink in the cartridge 7 becomes a predetermined value or less, information indicating the remaining amount of ink that has become the predetermined value or less may be stored in the memory. In this case, the printer 5 may determine that no ink is contained in the cartridge 7 and may not shift to a normal printing operation. In the present embodiment, in the information update step S40, the information regarding the ink consumption amount of the memory is updated to a usable value indicating that the ink is contained in a predetermined value or more. Thereby, when the cartridge 7 is mounted on the printer 5, the printer 5 normally shifts to the printing operation. If it is only necessary to inject ink, step S40 is unnecessary. In addition to rewriting the information in the storage device, step S40 can be performed by other methods such as replacing the circuit board 141. In the case of a new cartridge, step S40 can be performed by writing information about ink in the memory or attaching a circuit board having a memory in which such information is written to the cartridge.

[Example 1]
In the first embodiment, as an example of the injection step S30, an example in which an injection port 181 that directly communicates with the storage unit 109 is provided and ink is injected from the injection port 181 will be described. In FIG. 13, the injection port 181 is formed in the third wall 73 of the first case 62. The position where the injection port 181 is formed is not limited to the position shown in FIG. You may form in the other position of the 3rd wall 73 of the 1st case 62. FIG. In addition, if the inlet 181 is a position that directly communicates with the housing portion 109, the walls other than the third wall 73, that is, the first wall 71, the second wall 72, and the fourth wall 74 to the seventh wall 77 are provided. You may form in either. Furthermore, the injection port 181 may be formed at a place that can be regarded as a part of the first case 62, such as the prism unit 121 (FIG. 8) or the sheet member 123 (FIG. 8).

  Then, as shown in FIG. 13, the ink IK is injected from the injection port 181. In the first embodiment, when the injection port 181 is formed in the prism unit 121, the prism unit 121 has light transmittance, so that the injection amount of the ink IK can be easily recognized.

  After the ink IK is injected, the injection port 181 is sealed with a sealing member 185 as shown in FIG. FIG. 14 shows an example in which the inlet 181 is sealed by joining a sealing member 185 made of a plate material to the first case 62 with an adhesive, as compared to the first embodiment. Examples of the sealing member 185 include a plate material or sheet material made of resin or rubber, an adhesive, a plug made of resin or rubber, and the like. The method for sealing the inlet 181 is not limited to the bonding of the plate material. For example, before the injection step S30 is performed, after the injection port 181 is closed with the sealing member 185 having a self-sealing function, the injection needle is pierced into the sealing member 185, and the ink IK is injected through the injection needle If the injection needle is removed, the injection port 181 can be automatically sealed by the self-sealing function of the sealing member 185. As described above, when the sealing member 185 having a self-sealing function is used, it is easy to prevent air from flowing into the housing portion 109 from the injection port 181 when the injection needle 229 is extracted.

[Example 2]
In the second embodiment, as a second embodiment of the injection step S30, another example in which an injection port 181 that directly communicates with the storage unit 109 is provided and ink is injected from the injection port 181 will be described. In the first embodiment, the injection port 181 is formed in the first case 62, whereas in the second embodiment, the injection port 181 is formed in the sheet member 107. The second embodiment is different from the first embodiment in the position where the injection port 181 is formed, but is otherwise the same as the first embodiment, including effects and modifications.

  In the second embodiment, as illustrated in FIG. 15, the inlet 181 is formed in the sheet member 107 through the opening 183 provided in the second case 63. Then, after ink is injected from the injection port 181, the injection port 181 is sealed as shown in FIG. 16.

  The opening 183 can be formed by removing a part of the second case 63. Further, the position of the injection port 181 in the sheet member 107 is not particularly limited as long as it is a position that directly communicates with the housing portion 109. The position of the injection port 181 in the sheet member 107 may be a position overlapping the pressure receiving plate 105 or an outside of a region overlapping the pressure receiving plate 105. The opening 183 may be formed in the first case 62 instead of the second case 63. That is, the opening 183 can be formed by removing a part of the case 61.

  The size and shape of the opening 183 are arbitrary, and are not limited to a relatively small circular shape as shown in FIG. The opening 183 and the injection port 181 may be formed simultaneously by penetrating the second case 63 and the sheet member 107 simultaneously with a tool such as a drill. In this case, the opening 183 has substantially the same size and the same shape as the injection port 181.

  Further, instead of forming the opening 183 in the second case 63, the entire second case 63 may be removed. When a new cartridge is manufactured, the injection step S30 (FIG. 12) may be performed before the second case 63 is joined, that is, in a state where the second case 63 is not joined.

  Here, a state in which the second case 63 is removed or a state in which the second case 63 is not joined is referred to as a “state without the second case 63”. Further, the “state without the second case 63” is also included in removing a part of the case 61.

  If the second case 63 is not present, the housing portion 109 is exposed and the inside of the housing portion 109 is easily visible. Therefore, it is possible to efficiently carry out the cartridge manufacturing work, particularly the ink injection. In the first embodiment, there is no necessity to perform the injection step S30 (FIG. 12) without the second case 63. However, also in the first embodiment, if the ink injection process is performed in such a state, it is possible to efficiently perform the cartridge manufacturing work, particularly the ink injection.

  In the second embodiment, in addition to the method described in the first embodiment, the following method can be adopted for forming and sealing the injection port 181. First, after removing a part of the case 61 and before forming the inlet 181, a sealing member 185 having a self-sealing function is attached to a part of the sheet member 107 by adhesion or the like. Next, the injection port 181 is formed by piercing the injection needle so as to penetrate the sheet member 107 from above the sealing member 185. Finally, after the ink IK is injected through the injection needle and then the injection needle is removed, the injection port 181 can be automatically sealed by the self-sealing function of the sealing member 185. As described above, when the sealing member 185 having a self-sealing function is used, it is easy to prevent air from flowing into the housing portion 109 from the injection port 181 when the injection needle 229 is extracted.

[Example 3]
In the third embodiment, an example will be described in which a discharge port 187 is formed in the first case 62 in addition to the injection port 181 and the discharge port 187 is used in the discharge step S20 and the injection step S30. In the third embodiment, as shown in FIG. 17, in addition to the inlet 181 of the first embodiment (FIGS. 13 and 14), a discharge port 187 is formed in the first case 62. The discharge port 187 communicates with the inside of the housing portion 109 from the outside of the first case 62. Except for using the discharge port 187, it is the same as the first embodiment including effects and modifications.

  According to the third embodiment, when the ink IK is injected from the injection port 181, the atmosphere in the storage unit 109 can escape from the discharge port 187 to the outside of the storage unit 109. That is, the ink IK can be injected into the storage unit 109 while the air in the storage unit 109 escapes from the discharge port 187 to the outside of the storage unit 109. As a result, the ink IK can be easily introduced into the storage unit 109, so that the time required for injection can be reduced.

  Further, according to the third embodiment, the discharging step S20 can be performed before the ink IK is injected. For example, the inside of the housing portion 109 may be cleaned by injecting the cleaning liquid from the injection port 181 and discharging the cleaning liquid from the discharge port 187. Alternatively, the cleaning liquid may be injected from the discharge port 187 and discharged from the injection port 181. It is possible to obtain a cartridge with higher quality by injecting the ink IK after the substance in the container 109, such as ink or air, is discharged by washing.

  Further, in Example 3, after the ink injection is finished, the injection port 181 and the discharge port 187 are sealed. About the sealing method of the discharge port 187, the method similar to the sealing method of the injection port 181 is employable. Either the sealing of the inlet 181 and the sealing of the outlet 187 may be performed first or at the same timing.

  The place where the discharge port 187 is formed may be a position that directly communicates with the housing portion 109, and can be formed at various positions on the first case 62 as in the case of the injection port 181 described above.

  Further, the discharging step S20 can be performed by the following method other than the cleaning described above. With the container 109 substantially sealed (with the container 109 opened to the outside only in the discharge port 187), the inside of the container is sucked from the discharge port 187. Alternatively, a direction in which the housing portion compresses the sheet member 107 with the housing portion 109 opened to the outside with a part of the case 61 removed and the housing portion 109 substantially sealed (only at the discharge port 187). Press on. In any case, the substance in the accommodating portion 109, such as ink or air, can be discharged from the discharge port 187. Further, in the discharge step S20, air may be sent from the injection port 181 into the storage unit 109, and ink or dust in the storage unit 109 may be discharged from the discharge port 187 by the pressure.

[Example 4]
In the fourth embodiment, an example in which a discharge port 187 is formed in the sheet member 107 in addition to the injection port 181 and the discharge port 187 is used in the discharge step S20 and the injection step S30 will be described. In Example 3, as shown in FIG. 18, in addition to the injection port 181 of Example 2 (FIGS. 15 and 16), a discharge port 187 is formed in the sheet member 107. The discharge port 187 is used in the same manner as the discharge port 187 of the third embodiment in the discharge step S20 and the injection step S30, thereby bringing the same effect as described in the third embodiment.

  In Example 4, after the ink injection is completed, the injection port 181 and the discharge port 187 are sealed. The discharge port 187 can be sealed by the same method as the method for sealing the injection port 181 of the second embodiment described above. Either the sealing of the inlet 181 and the sealing of the outlet 187 may be performed first or both may be performed at the same timing.

  The discharge port 187 may be formed at any position on the sheet member 107 as in the case of the injection port 181 of the second embodiment described above. is there. As shown in FIG. 18, in Example 4, the inlet 181 and the outlet 187 are formed through the opening 183. The opening 183 can be formed in the same position, size, and shape as the opening 183 of the second embodiment. In FIG. 18, the inlet 181 and the outlet 187 are formed through a common opening 183. However, these may be formed through separate openings. Such separate openings can also be formed by the same method as the opening 183 of the second embodiment. Further, by passing the second case 63 and the sheet member 107 through two places with a tool such as a drill, the first opening and the inlet 181 are formed simultaneously, and the second opening and the outlet 187 are formed. You may make it form simultaneously. Further, as in the second embodiment, instead of forming the opening 183 in the second case 63, the second case 63 may be omitted. If the second case 63 is not present, it is possible to efficiently carry out the cartridge manufacturing work, particularly the ink injection.

  In short, both the injection port 181 and the discharge port 187 of the fourth embodiment can be formed by removing a part of the case 61, and the removed portion is common to the injection port 181 and the discharge port 187. The position may be a different position.

[Example 5]
In the fifth embodiment, an example in which the inlet 181 is formed in the first case 62, the outlet 187 is formed in the sheet member 107, and the outlet 187 is used in the discharging step S20 and the injection step S30 will be described. In the fifth embodiment, as shown in FIG. 19, in addition to the inlet 181 of the cartridge shown in the first embodiment (FIGS. 13 and 14), a discharge port 187 is formed in the sheet member 107. The discharge port 187 can be formed at various positions by various methods, similar to the injection port 181 of the second embodiment. FIG. 19 shows a state in which the discharge port 187 is formed in the sheet member 107 through the opening 183 provided in the second case 63 as an example. The discharge port 187 is used in the same manner as the discharge port of the third embodiment, and thus provides the same effect as described in the third embodiment.

  In Example 5, after the ink injection is completed, the injection port 181 and the discharge port 187 are sealed. The discharge port 187 can be sealed by the same method as the method for sealing the injection port 181 of the second embodiment described above. Moreover, either the sealing of the inlet 181 and the sealing of the outlet 187 may be performed first, or both may be performed at the same timing.

[Example 6]
In the sixth embodiment, an example in which the injection port 181 is formed in the sheet member 107, the discharge port 187 is formed in the first case 62, and the discharge port 187 is used in the discharge step S20 and the injection step S30 will be described. In the sixth embodiment, as shown in FIG. 20, in addition to the injection port 181 of the cartridge shown in the second embodiment (FIGS. 15 and 16), a discharge port 187 is formed in the first case 62. The discharge port 187 can be formed at various positions by various methods, similar to the injection port 181 of the first embodiment. FIG. 20 shows a state where the discharge port 187 is formed near the center of the third wall 73 as an example. The discharge port 187 is used in the same manner as the discharge port of the third embodiment, and thus provides the same effect as described in the third embodiment.

  In Example 6, the injection port 181 and the discharge port 187 are sealed after the ink injection is completed. The discharge port 187 can be sealed by the same method as the injection port 181 of the first embodiment described above. Moreover, either the sealing of the inlet 181 and the sealing of the outlet 187 may be performed first, or both may be performed at the same timing.

[Example 7]
Instead of providing the discharge port 187 of the third to sixth embodiments, the air introduction port 171 can be opened and used as the discharge port. By using the air introduction port 171 as the discharge port, the same effects as those of the third to sixth embodiments can be obtained. In the discharge step S20 and the injection step S30, the specific method of using the discharge port is as described in the third embodiment, and thus detailed description is omitted. According to this method, the discharge port 187 can be omitted. In order to open the atmosphere introduction port 171, as shown in FIG. 21, for example, an external force may be applied to the valve portion 173 in the direction of the arrow in the drawing. That is, the air inlet 171 may be forcibly opened by pressing the valve portion 173.

  FIG. 22 shows an example in which the air introduction port 171 is used as a discharge port with respect to the first embodiment. FIG. 23 shows an example in which the air introduction port 171 is used as a discharge port with respect to the second embodiment. In either case, an opening 191 is formed in the second case 63. The opening 191 is formed in a region that overlaps the air inlet 171 when the second case 63 is viewed in plan in the Y-axis direction. The air inlet 171 can be exposed through the opening 191. Then, by applying an external force to the valve portion 173 through the opening portion 191, the atmosphere introduction port 171 can be opened.

  The position where the opening 191 is formed is not limited to the position shown in FIGS. 21 to 23 as long as the atmosphere introduction port 171 can be exposed. The size and shape of the opening 191 are arbitrary, and are not limited to a comparatively small circular shape as shown in FIGS. You may make it press the valve part 173 simultaneously with penetrating the 2nd case 63 with a tool like a drill. Further, instead of forming the opening 191 in the second case 63, the second case 63 may be absent. If the second case 63 is not provided, it is possible to efficiently manufacture the cartridge, particularly the ink injection.

  In short, the air inlet 171 can be exposed by removing a part of the case 61.

  In Examples 3 to 6, the discharge port 187 was sealed after the ink injection was completed. In the seventh embodiment, the atmosphere introduction port 171 as the discharge port 187 can be sealed by closing the atmosphere introduction port 171. Specifically, the air introduction port 171 is closed by removing the external force (force in the direction of the arrow in FIG. 21) that has been applied to the valve portion 173. Further, if the valve portion 173 is destroyed in the process of forcibly opening the air introduction port 171, the air introduction port may be sealed by the same method as in the third to sixth embodiments. Sealing the inlet 181 and sealing the air inlet 171 as a discharge port (work to close the air inlet 171) are performed at the same timing, regardless of which is performed first. May be.

  According to the seventh embodiment, since the discharge port 187 can be omitted, the cartridge can be manufactured more simply than in the third to sixth embodiments.

[Example 8]
Instead of providing the discharge port 187 of the third to sixth embodiments, the supply port 85 can be used as a discharge port. By using the supply port 85 as a discharge port, the same effects as those of the third to sixth embodiments can be obtained. In the discharge step S20 and the injection step S30, the specific method of using the discharge port is as described in the third embodiment, and thus detailed description is omitted. According to this method, the discharge port 187 can be omitted.

  FIG. 24 shows an example in which the supply port 85 is used as a discharge port with respect to the first embodiment. FIG. 25 shows an example in which the supply port 85 is used as a discharge port with respect to the second embodiment.

  According to the eighth embodiment, since the discharge port 187 can be omitted, the cartridge can be manufactured more simply than in the third to sixth embodiments. Further, since it is not necessary to expose or forcibly open the air introduction port 171, it becomes possible to manufacture the cartridge more easily than in the seventh embodiment.

[Example 9]
In the first and second embodiments, the injection port 181 is formed in the cartridge 7, and the ink IK is injected into the storage unit 109 from the injection port 181. However, it is also possible to inject the ink IK into the storage unit 109 from the supply port 85 without forming the injection port 181. An example in which the ink IK is injected from the supply port 85 into the storage unit 109 without forming the injection port 181 is referred to as Example 9. In the ninth embodiment, as shown in FIG. 26, the ink IK is injected from the supply port 85 through the filter 135. In the example shown in FIG. 26, the ink IK is dropped and injected from above in a state where the cartridge 7 is in such a posture that the supply port 85 is on the top. According to the ninth embodiment, unlike the first and second embodiments, it is not necessary to form or seal the injection port 181, so that the cartridge is simpler than the methods of the first and second embodiments. Can be manufactured.

[Example 10]
In contrast to the ninth embodiment, as in the third to sixth embodiments, the discharge port 187 may be formed, and the discharge port 187 may be used in the discharge step S20 and the injection step S30. FIG. 27 shows an example in which a discharge port 187 is formed in the first wall 71 of the first case 62.

  In the example illustrated in FIG. 27, the position where the discharge port 187 is formed may be a position that directly communicates with the housing portion 109, as in the third and sixth embodiments, and the first wall 71 of the first case 62 has It is not limited.

  Further, FIG. 28 shows an example in which a discharge port 187 is formed in the sheet member 107. In the example shown in FIG. 28, the position where the discharge port 187 is formed is not limited to the position shown in FIG. 28 as long as it is a position that directly communicates with the accommodating portion 109, as in the fourth and fifth embodiments.

  These discharge ports 187 are used in the same manner as the discharge ports 187 of the third to sixth embodiments, thereby providing the same effects as those described in the third to sixth embodiments. Since the position and shape of the discharge port 187, the method of forming the discharge port 187, and the method of sealing the discharge port 187 are as described above in the third to sixth embodiments, detailed description thereof is provided. Is omitted.

[Example 11]
In contrast to the ninth embodiment, instead of providing the discharge port 187 of the tenth embodiment, the same effect as that of the tenth embodiment can be obtained by opening the atmosphere introduction port 171 and using this as the discharge port. it can. Moreover, according to this method, since the discharge port 187 can be omitted, the same effect as in the seventh embodiment can be obtained. The method for opening the atmosphere introduction port 171 and the method for sealing the atmosphere introduction port 171 as the discharge port after the completion of the ink injection are as described in the seventh embodiment, including the modification. Therefore, detailed description is omitted.

  FIG. 29 shows an example in which the air introduction port 171 is used as the discharge port with respect to the ninth embodiment. In the eleventh embodiment, an opening 191 is formed in the second case 63, and the air inlet 171 is pushed open therefrom. The opening 191 can be formed by the same position, size, shape, and method as the opening 191 described in the seventh embodiment.

  According to the eleventh embodiment, since the discharge port 187 can be omitted, the cartridge can be manufactured more easily than the tenth embodiment.

[Example 12]
It is possible to implement discharge process S20 by giving the force which compresses accommodating part 109 to the above-mentioned Example 9. Moreover, injection | pouring process S30 can be implemented by providing the force which expands the volume of the accommodating part 109. FIG. Such a force can be applied by pressurizing or depressurizing the space outside the housing portion 109.

  In FIGS. 30 and 32, with respect to the ninth embodiment, by pressing the space outside the storage unit 109, that is, the atmospheric chamber 115, substances in the storage unit 109, such as ink and air, are supplied from the supply port 85. An example of discharging is shown.

  31 and 33 show an example in which the ink IK is injected into the storage unit 109 by depressurizing the space outside the storage unit 109, that is, the atmospheric chamber 115, with respect to the ninth embodiment.

  In the example shown in FIG. 30, the communication hole 91 is closed with a plug 93 or the like so that ink and air do not flow from the communication hole 91. Then, the supply port 85 is immersed in the ink fountain 95. Thereafter, the pressure increasing / decreasing device 97 is attached to the atmosphere communication hole 113, and the inside of the cartridge is pressurized through the atmosphere communication hole 113 as shown by an arrow in FIG. Then, the atmospheric chamber 115 is pressurized, and the accommodating portion 109 is compressed. Due to this force, the substance in the accommodating portion 109, such as ink or air, is discharged from the supply port 85. Next, the inside of the cartridge is depressurized by the pressure-intensifying device 97. Specifically, the pressurization is released from the state of FIG. 30, and the atmospheric chamber 115 is returned to the atmospheric pressure. Then, as indicated by an arrow in FIG. 31, the atmospheric chamber 115 is depressurized, and the sheet member 107 is pulled in a direction that expands the volume of the accommodating portion 109. With this force, the ink IK is drawn into the storage unit 109 from the supply port 85 through the filter 135.

  On the other hand, in the example shown in FIG. 32, the air communication hole 113 is closed with a plug 93 or the like, and the pressure increasing / decreasing device 98 is attached to the communication hole 91. Then, as shown by an arrow in FIG. 32, the inside of the cartridge is pressurized through the communication hole 91. Then, the atmospheric chamber 115 is pressurized, and the accommodating portion 109 is compressed. Due to this force, the substance in the accommodating portion 109, such as ink or air, is discharged from the supply port 85. Next, the inside of the cartridge is depressurized by the pressure-intensifying device 98. Specifically, the pressurization is released from the state of FIG. 32, and the atmospheric chamber 115 is returned to the atmospheric pressure. Then, as indicated by an arrow in FIG. 33, the atmospheric chamber 115 is depressurized, and the sheet member 107 is pulled in a direction that expands the volume of the accommodating portion 109. With this force, the ink IK is drawn into the storage unit 109 from the supply port 85 through the filter 135.

  According to the twelfth embodiment, it is possible to manufacture a cartridge with higher quality by discharging the substance in the container 109, for example, ink or air, before injecting the ink IK. Further, when the ink IK is injected, the time required for the injection can be shortened by applying a force that draws the ink IK into the storage unit 109 by reducing the pressure outside the storage unit 109. Further, according to the present embodiment, since the discharging process and the injecting process can be performed without making a hole or scratching the cartridge, it is possible to manufacture the cartridge more easily than the 10th and 11th embodiments. it can. Further, in the example shown in FIGS. 30 and 31, the atmosphere communication chamber 113 is used to pressurize and depressurize the atmosphere chamber 115. Further, in the example shown in FIGS. 32 and 33, the communication chamber 91 is used to pressurize and depressurize the atmospheric chamber 115. Thus, in Example 12, since the discharge process and the injection process can be continuously performed using the same hole, the cartridge can be manufactured efficiently.

[Example 13]
In the twelfth embodiment, the atmospheric chamber 115 is depressurized using the atmospheric communication hole 113 and the communication hole 91 in order to apply a force for compressing and expanding the accommodating portion 109. Instead, it is also possible to pressurize and depressurize the space outside the housing portion 109 without the second case 63. FIG. 34 shows an example in which a force for compressing the accommodating portion 109 is applied to the ninth embodiment without the second case. FIG. 35 shows an example in which a force for expanding the volume of the accommodating portion 109 is applied to the ninth embodiment without the second case.

  In Example 13, first, the second case 63 is removed. Further, the communication hole 91 is closed with a plug 93 or the like so that ink or air does not flow from the communication hole 91 in the state where there is no second case. Then, the supply port 85 is immersed in the ink fountain 95. Thereafter, as shown in FIG. 34, a pressure increasing / decreasing device 99 is attached to the side opposite to the accommodating portion 109 of the sheet member 107. As a result, the area corresponding to the accommodating portion 109 is sealed. At this time, an airtight space 197 formed on the outer side of the housing portion 109 by the pressurizing and depressurizing device 99 becomes a space corresponding to the atmospheric chamber 115 of the twelfth embodiment. In this state, as shown by the arrow in FIG. 34, when the space 197 is pressurized, the accommodating portion 109 is compressed. Due to this force, the substance in the accommodating portion 109, such as ink or air, is discharged from the supply port 85. Next, the space 197 is decompressed by the pressurizing and depressurizing device 99. Specifically, the pressure is released from the state of FIG. 34, and the space 197 is returned to atmospheric pressure. Then, as indicated by an arrow in FIG. 35, the space 197 is decompressed, and the sheet member 107 is pulled in a direction that expands the volume of the accommodating portion 109. With this force, the ink IK is drawn into the storage unit 109 from the supply port 85 through the filter 135.

  According to the thirteenth embodiment, it is possible to manufacture a cartridge with higher quality by discharging the substance in the container 109, for example, ink or air, before injecting the ink IK. Further, when the ink IK is injected, the time required for the injection can be shortened by applying a force that draws the ink IK into the storage unit 109 by reducing the pressure outside the storage unit 109. In addition, according to the present embodiment, since the discharge process and the injection process can be continuously performed using the same space 197, the cartridge can be manufactured efficiently.

[Example 14]
In the twelfth and thirteenth embodiments, a force for compressing or expanding the accommodating portion 109 is applied from the outside of the accommodating portion. Instead, it is possible to apply such a force by depressurizing the accommodating portion 109 from the supply port 85.

  In FIG. 36, the container 109 is decompressed from the supply port 85 to discharge the substance in the container 109, such as ink or air, from the supply port 85, and then the ink IK is discharged from the supply port 85. An example of injection is shown. In Example 14, first, the communication hole 91 is closed with a plug 93 or the like so that the atmosphere does not flow out of the communication hole 91. Next, the supply port 85 is covered with the reduced pressure injection device 100. Specifically, the inside of the supply port 85 is set in an airtight state. In this state, the accommodating portion 109 is depressurized through the supply port 85. Specifically, as indicated by an arrow in FIG. 36, a substance in the storage unit 109, for example, ink or air, is sucked and discharged to the outside. At this time, the volume of the accommodating portion 109 is reduced.

  Next, ink is sent out from the supply port 85 to the storage unit 109 by the vacuum injection device 100. Specifically, the ink is sent to the supply port 85 as indicated by an arrow in FIG. Since the accommodating portion 109 is first reduced and reduced, the difference between the pressure inside the accommodating portion 109 and the atmospheric pressure outside the accommodating portion 109 is large. Therefore, the ink delivered to the supply port 85 is smoothly drawn into the storage unit 109 using the force generated by the pressure difference inside and outside the storage unit 109.

  According to the fourteenth embodiment, it is possible to manufacture a cartridge with higher quality by discharging the substance in the container 109, such as ink or air, before injecting the ink IK. In addition, when the ink IK is injected, the time required for the injection can be shortened by applying a force that draws the ink IK into the storage portion by reducing the pressure of the storage portion 109. In addition, according to the fourteenth embodiment, since the discharging process and the injecting process can be performed without making a hole or scratching the cartridge, the cartridge can be manufactured more easily than the tenth and eleventh embodiments. it can. Furthermore, in Example 14, since the discharge process and the injection process can be continuously performed using the same ink supply port 85, the cartridge can be manufactured efficiently.

[Example 15]
When the ink IK is injected into the storage unit 109 from the supply port 85, the negative pressure in the storage unit 109 can be used. In the cartridge 7 of the present embodiment, the sheet member 107 is urged in a direction in which the volume of the accommodating portion 109 is expanded by a coil spring 103 as an urging member. Therefore, if the volume of the storage unit 109 is reduced to some extent, a negative pressure is generated in the storage unit 109. For example, in the case of a cartridge immediately after use, the storage unit 109 is compressed due to consumption of ink. At this time, since the air communication hole 113 is in a closed state, air does not flow into the housing portion 109 from the air communication hole 113. Further, as long as the filter 135 of the supply port 85 is wet with ink, air does not flow into the housing portion 109 from the supply port 85. Even if the filter 135 is dry and air is flowing into the housing portion 109, the housing portion 109 can be pressed by pressing the housing portion 109 from the outside of the sheet member 107 by removing a part of the case 61. 109 can be compressed. The same applies when manufacturing a new cartridge.

  Thus, in the cartridge 7 of this embodiment, a state in which a negative pressure is generated in the housing portion 109 can be easily created. If a negative pressure is generated in the storage unit 109, as shown in FIG. 38, the ink is drawn into the storage unit 109 from the supply port 85 simply by immersing the supply port 85 in the ink fountain 95.

  That is, as shown in FIG. 38, by immersing the supply port 85 of the cartridge in a state where a negative pressure is generated in the storage unit 109 in the ink fountain 95, the negative pressure generated in the storage unit 109 is used. You may make it inject | pour ink into the accommodating part 109 from the supply port 85. FIG. In this way, it is possible to simply inject ink without performing the pressurization or decompression as described in the twelfth to fourteenth embodiments.

[Example 16]
A reduced-pressure atmosphere may be used to apply a force for reducing or expanding the accommodating portion 109. In the sixteenth embodiment, an example will be described in which a force for reducing or expanding the accommodating portion 109 is applied by using the reduced pressure atmosphere.

  First, as shown in FIG. 39, the communication hole 91 and the air communication hole 113 are closed in an atmospheric pressure atmosphere. That is, the atmosphere chamber 115 is a sealed space. Then, the ink supply port 85 is immersed in the ink fountain 95. Next, the cartridge is placed in a reduced-pressure atmosphere while maintaining the state of FIG. For example, as shown in FIG. 40, after the cartridge 91 in which the communication hole 91 and the atmosphere communication hole 113 are closed and the ink supply port 85 is immersed in the ink bottle 95 is accommodated in the decompression container 199, the interior of the decompression container 199 is decompressed. To do. The decompression container 199 is a container having strength that can withstand a decompression environment. At this time, since the atmospheric chamber 115 is sealed, the atmospheric pressure is maintained. On the other hand, the container 109 communicates with the external atmosphere through the ink supply port 85. Therefore, the storage unit 109 is decompressed, and the substance in the storage unit 109, such as ink or air, is discharged to the outside through the ink supply port 85.

  Finally, as shown in FIG. 41, the cartridge is returned to the atmospheric pressure atmosphere while maintaining the state of FIG. In the process shown in FIG. 39, the storage portion 109 is reduced in pressure and reduced, whereas the atmospheric chamber 115 remains at atmospheric pressure. Therefore, the difference between the pressure in the accommodating portion 109 and the atmospheric pressure in the atmospheric chamber 115 is large.
