The present disclosure relates to a technology of a cartridge and a liquid ejecting apparatus.
In the related art, a cartridge for supplying ink to a printer has been known (for example, PTL 1).
PTL 1: Japanese Unexamined Patent Application Publication No. 2017-024423
In the related art, a cartridge includes a printing material lead-out tube and a circuit substrate that is in contact with an apparatus-side terminals. When the ink leaks from the printing material lead-out tube, there is a concern that the leaked ink adheres to the circuit substrate. When the ink adheres to the circuit substrate, there is a concern that a contact failure with the apparatus-side terminal occurs. Such a problem is not limited to a cartridge including a circuit substrate and a printing material lead-out tube, and is common to a cartridge including a contact portion that is in contact with an apparatus-side terminal of a liquid ejecting apparatus and a liquid supply port.
(1) According to one aspect of the present disclosure, there is provided a cartridge detachably mounted on a liquid ejecting apparatus. The cartridge includes: a case including a front surface and a back surface opposing each other, a top surface and a bottom surface intersecting the front surface and the back surface and opposing each other, and a first side surface and a second side surface intersecting the front surface, the back surface, the top surface, and the bottom surface and opposing each other; a liquid supply port that is disposed on the front surface, is coupled to a liquid introduction section of the liquid ejecting apparatus, and supplies a liquid to the liquid introduction section; and a contact portion that is disposed at a corner where the front surface and the top surface intersect each other and is in contact with an apparatus-side terminal of the liquid ejecting apparatus, the liquid supply port is disposed at the center of the case in a width direction in which the first side surface and the second side surface oppose each other, and the contact portion is disposed at a position shifted to one side of the first side surface and the second side surface in the width direction.
The printer 10 of the present embodiment is an ink jet printer that discharges ink from a head 22. The printer 10 is a printer that performs printing on photo paper or the like. The printer 10 includes a mounting section 6, a control section 31, a carriage 20, the head 22, and a driving mechanism 30. Further, the printer 10 includes an operation button 15 for a user to operate an operation of the printer 10.
A plurality of cartridges 4 are detachably mounted on the mounting section 6, respectively. In the present embodiment, four types of cartridges 4 are mounted one by one corresponding to four colors (black, yellow, magenta, and cyan) of ink, that is, a total of four cartridges 4 are mounted on the mounting section 6. A mounting direction of the cartridge 4 to the mounting section 6 is the −Y axis direction, and a removing direction is the +Y axis direction. In another embodiment, three or less cartridges 4 or five or more cartridges 4 may be detachably mounted on the mounting section 6. Further, in the printer 10 of the present embodiment, a replacement cover 13 is provided on the front surface (a surface on the +Y axis direction side). When the +Z axis direction side of the replacement cover 13 is tilted toward a near side (+Y axis direction side), an opening of the mounting section 6 appears, and the cartridge 4 can be attached and detached. When the cartridge 4 is mounted on the mounting section 6, ink can be supplied to the head 22 provided on the carriage 20 via a tube 24. In the present example, when a pressurized fluid is introduced into the cartridge 4 from the printer 10, the ink is supplied to the head 22 from a liquid storage bag of the cartridge 4. In addition, the tube 24 is provided for each type of ink. A state where the cartridge 4 is mounted on the mounting section 6 is also referred to as a “mounted state”.
The head 22 is provided with nozzles for each type of ink. The head 22 ejects ink from ejection nozzles toward a printing paper sheet 2 to print data such as characters or images. The detailed configuration of the cartridge 4 and the mounting section 6 will be described later. In the present embodiment, the printer 10 is a so-called “off-carriage type” printer in which the mounting section 6 does not interlock with the movement of the carriage 20. The present disclosure is also applicable to a so-called “on-carriage type” printer in which the mounting section 6 is provided on the carriage 20 and the mounting section 6 moves together with the carriage 20.
The control section 31 controls each section of the printer 10 and exchanges signals with the cartridge 4. The carriage 20 moves the head 22 relatively to the printing paper sheet 2.
The driving mechanism 30 reciprocates the carriage based on a control signal from the control section 31. The driving mechanism 30 includes a timing belt 32 and a drive motor 34. By transmitting the power of the drive motor 34 to the carriage 20 via the timing belt 32, the carriage 20 reciprocates in a main scanning direction (X axis direction). Further, the printer 10 includes a transport mechanism for moving the printing paper sheet 2 in a sub-scanning direction (+Y axis direction). When printing is performed, the printing paper sheet 2 is moved in the sub-scanning direction by the transport mechanism, and the printing paper sheet 2 after the printing is completed is output onto a front cover 11.
A region called a home position is provided at a position outside a printing region where the carriage 20 is moved in the main scanning direction, and a maintenance mechanism for performing maintenance such that printing can be performed normally is installed at the home position. The maintenance mechanism includes a cap member 8 that is pressed against a surface (nozzle surface) on which the nozzles are formed on the bottom surface side (the side facing the printing paper sheet 2) of the head 22 to form a closed space that surrounds the ejection nozzles. Further, the maintenance mechanism has an elevating mechanism (not illustrated) that elevates and lowers the cap member 8 in order to press the cap member against the nozzle surface of the head 22. Further, the maintenance mechanism has a suction pump (not illustrated) for introducing a negative pressure into the closed space formed by pressing the cap member 8 against the nozzle surface of the head 22.
In the present embodiment, in the use state of the liquid ejection system 1 (the printer 10 and the cartridge 4), the axis along the sub-scanning direction in which the printing paper sheet 2 is transported is set as the Y axis, and the axis along the vertical direction (up-down direction) is set as the Z axis, and the axis along the moving direction (left-right direction) of the carriage 20 is set as the X axis. Here, the “use state of the liquid ejection system 1” refers to a state where the liquid ejection system 1 is installed on a horizontal surface. In the present embodiment, the sub-scanning direction (forward direction) is set as the +Y axis direction, the direction opposite thereto (rearward direction) is set as the −Y axis direction, the direction (upward direction) upward from below in the vertical direction is set as the +Z axis direction, and the direction (downward direction) opposite thereto is set as the −Z axis direction. When the liquid ejection system 1 is viewed from the front side (+Y axis direction side), the direction from the right side to the left side is set as the +X axis direction, and the direction opposite thereto is set as the −X axis direction. Further, in the present embodiment, an insertion direction when the cartridge 4 is mounted on the mounting section 6 is also the −Y axis direction, and the direction when the cartridge 4 is removed from the mounting section 6 is also the +Y axis direction. Accordingly, in the mounting section 6, the −Y axis direction side is also referred to as a far side, and the +Y axis direction side is also referred to as a near side. In the present embodiment, an arrangement direction of the plurality of cartridges 4 is also the X axis direction.

The engagement mechanism 88 regulates the movement of the cartridge 4 in the mounted state in the removing direction (+Y axis direction) by being engaged with the cartridge 4. The engagement mechanism 88 is disposed on the mounting section upper wall 602. The engagement mechanism 88 is a lever, and includes an operating section 882, a rotation shaft 89, and an apparatus-side engaging section 881. The operating section 882 is exposed to the outside of the mounting section 6 such that the user can operate the operating section. The operating section 882 is positioned at one end portion of the engagement mechanism 88. The apparatus-side engaging section 881 is positioned at the other end portion of the engagement mechanism 88 and on the inside of the mounting section 6. The engagement mechanism 88 has a spring member (not illustrated), and the apparatus-side engaging section 881 is disposed at a position illustrated in
In the mounted state of the cartridge 4, the apparatus-side terminal portion 70 comes into contact with and is electrically coupled to a circuit substrate (which will be described later) of the cartridge 4. The apparatus-side terminal portion 70 is disposed on the mounting section back wall 601. The apparatus-side terminal portion 70 may be disposed on the mounting section upper wall 602 or may be disposed between the mounting section back wall 601 and the mounting section upper wall 602. The apparatus-side terminal portion 70 includes a terminal holding section 71 and an apparatus-side terminal 72. The terminal holding section 71 is a member that holds the apparatus-side terminal 72. The apparatus-side terminal 72 is a metal plate member, and a part thereof is exposed from a surface 71fa of the terminal holding section 71. A plurality of apparatus-side terminals 72 are arranged. In the present embodiment, nine apparatus-side terminals 72 (only two are illustrated in the drawing) are provided. The apparatus-side terminal 72 has elasticity, and the degree of exposure (protrusion) from the surface 71fa can be changed by elastically deforming. A normal vector of the surface 70fa has the +Y axis direction component and the −Z axis direction component. The surface 70fa is inclined with respect to the mounting direction of the cartridge 4 to the mounting section 6 (−Y axis direction, horizontal direction).
The first apparatus-side positioning section 82 and the second apparatus-side positioning section 84 are respectively column-like members (columnar members) that extend from the mounting section back wall 601 in the +Y axis direction. The first apparatus-side positioning section 82 and the second apparatus-side positioning section 84 respectively extend in the +Y axis direction side of the apparatus-side identification member 81. In other words, the distal end portion of the first apparatus-side positioning section 82 and the distal end portion of the second apparatus-side positioning section 84 are respectively positioned in the +Y axis direction side of the apparatus-side identification member 81. The first apparatus-side positioning section 82 and the second apparatus-side positioning section 84 suppress displacement of the cartridge 4 within a plane (within a plane parallel to the X axis direction and the Z axis direction) orthogonal to the mounting direction during the mounting process of the cartridge 4 to the mounting section 6. The first apparatus-side positioning section 82 is positioned between the apparatus-side terminal 72 and the liquid introduction section 85 in the Z axis direction. The second apparatus-side positioning section 84 is positioned below the liquid introduction section 85 and the pressurizing section 86 in the Z axis direction. As illustrated in
The liquid introduction section 85 (
The apparatus-side identification member 81 is used to identify whether the correct type (ink color in the present embodiment) of the cartridge 4 is inserted into the storage space 600. The apparatus-side identification member 81 forms different shapes according to the color of the ink in the cartridge 4 to be mounted. Specifically, as illustrated in

Each of the nine cartridge-side terminals 831 to 839 is formed in a substantially rectangular shape, and has a contact portion cp that comes into contact with the corresponding apparatus-side terminal 72 of the mounting section 6. The four contact portions cp of the cartridge-side terminals 831 to 834 form a row Ln2 in which the contact portions are arranged in the X direction. Further, the five contact portions cp of the cartridge-side terminals 835 to 839 form a row Ln1 in which the contact portions are arranged in the X direction and which is different from the row in which the contact portions cp of the cartridge-side terminals 831 to 834 are arranged. In other words, the plurality of contact portions cp form the plurality of rows Ln1 and Ln2. In the present embodiment, each of the contact portions cp of the cartridge-side terminals 831 to 839 is arranged alternately. Specifically, each of the contact portions cp is arranged in a so-called staggered manner.
As illustrated in
Each of the cartridge-side terminals 831 to 839 (FIG. 9) can be called as follows from the function (use).
(1) Mounting detection terminal (first terminal) 835
(2) Power supply terminal 836
(3) Ground terminal 837
(4) Data terminal 838
(5) Mounting detection terminal (second terminal) 839
(6) Mounting detection terminal (third terminal) 831
(7) Reset terminal 832
(8) Clock terminal 833
(9) Mounting detection terminal (fourth terminal) 834
The four mounting detection terminals 831, 834, 835, and 839 are used for detecting whether or not the cartridge 4 is mounted in the mounting section 6 as the control section 31 detects the quality of the electrical contact with the corresponding apparatus-side terminal 72 (
The other five terminals 832, 833, 836, 837, and 838 are terminals for the storage device 820. The reset terminal 832 receives supply of a reset signal RST to the storage device 820. The clock terminal 833 receives supply of a clock signal SCK to the storage device 820. The power supply terminal 836 receives supply of a power source voltage VDD (for example, rated 3.3 V) to the storage device 820. The ground terminal 837 receives supply of a ground voltage VSS (0 V) to storage device 820. The data terminal 838 receives supply of a data signal SDA exchanged between storage device 820 and printer 10.

The first case 421 has a recessed shape that opens on the +X axis direction side. The first case 421 mainly forms a part of the front surface 401, a part of the back surface 404, a part of the top surface 402, a part of the bottom surface 403, a first side surface 405, and the corner 48. At the part of the front surface 401 formed by the first case 421, the first cartridge-side positioning hole 42, the second cartridge-side positioning hole 44, the arrangement recessed portion 411, the fluid receiving section 46, and the arrangement hole 424 which are described above are formed. The above-described cartridge-side engaging section 426 is formed at a part of the top surface 402 formed by the first case 421. The first case 421 further has engagement claws 442, and forms the case 40 by being engaged with the second case 427.
The sheet member 423 is a thin film member. The sheet member 423 is airtightly attached to an end surface that defines an opening 429 so as to seal the opening 429 on the +X axis direction side of the first case 421. By sealing the opening 429 with the sheet member 423, an internal chamber 430 that stores the liquid storage bag 50 and the auxiliary member 59 is defined. The pressurized fluid is introduced into the internal chamber 430 via the fluid receiving section 46.
The second case 427 is attached to the first case 421 so as to cover the sheet member 423. Specifically, the second case 427 is attached to the first case 421 by being engaged with the engagement claws 442. The second case 427 mainly forms another part of the front surface 401, another part of the back surface 404, another part of the top surface 402, another part of the bottom surface 403, and the second side surface 406.
The liquid supply section 49 is cylindrical and extends along the Y axis direction. The liquid supply section 49 has a center axis CT parallel to the Y axis direction. The liquid supply section 49 has a liquid supply port 481 that forms a distal end portion, and a base end portion 482 attached to the liquid storage bag 50. The base end portion 482 of the liquid supply section 49 is open in the liquid storage bag 50. The liquid supply section 49 forms a flow path that allows the liquid in the liquid storage bag 50 to flow toward the liquid supply port 481. Further, a valve mechanism is disposed on the inside of the liquid supply section 49, and the valve mechanism is in an open state by inserting the liquid introduction section 85 into the liquid supply section 49.
The liquid storage bag 50 that stores the liquid has a substantially rectangular parallelepiped shape, and is stored in the case 40 (specifically, the internal chamber 430). When the shape of the liquid storage bag 50 is described, it is assumed that the liquid illustrated in
The liquid storage bag 50 stores the liquid to be supplied to the printer 10. The liquid storage bag 50 has flexibility, and the volume decreases as the liquid is consumed. Specifically, the liquid storage bag 50 has a godet portion (fold) 515 that extends in the Y axis direction on a bag top surface 51 and a bag bottom surface 52, respectively. Due to the godet portion 515, the dimension of the liquid storage bag 50 in the X direction gradually decreases as the liquid is consumed.
The liquid storage bag 50 has a storage bag end portion 54 as a distal end portion, the bag top surface 51, the bag bottom surface 52, a rear end portion 55, a bag left side surface 56, and a bag right side surface 57.
The storage bag end portion 54 is positioned on the −Y axis direction side. The base end portion 482 is attached to the storage bag end portion 54. The storage bag end portion 54 has a distal end side 541 that forms an end on the −Y axis direction side, and a tapered portion 53. The tapered portion 53 has an end portion on the −Y axis direction side coupled to the distal end side 541, and an end portion on the +Y axis direction side coupled to the bag left side surface 56 and the bag right side surface 57. The dimension of the tapered portion 53 in the width direction (X axis direction) gradually decreases as going toward the liquid supply port 481 side (−Y axis direction side) of the liquid supply section 49. By providing the tapered portion 53, when the liquid storage bag 50 is stored in the case 40, a space (gap) is generated between the inner wall surface of the case 40 and the tapered portion 53.
The rear end portion 55 opposes the storage bag end portion 54 in the Y axis direction. The rear end portion 55 is positioned on the +Y axis direction side. The rear end portion 55 is bent toward the +Y axis direction side as illustrated in
The bag top surface 51 is positioned on the +Z axis direction side. The bag bottom surface 52 opposes the bag top surface 51 in the Z axis direction. The bag bottom surface 52 is positioned on the −Z axis direction side. The bag left side surface 56 is positioned on the −X axis direction side. The bag right side surface 57 opposes the bag left side surface 56 in the X direction. The bag right side surface 57 is positioned on the +X axis direction side.
The ring member 58 is disposed on the outer periphery of the liquid supply section 49 so as to surround the distal end side of the liquid supply section 49. The ring member 58 is, for example, a rubber member and is disposed in the arrangement hole 424 together with the liquid supply port 481. As the ring member 58 is in contact with the arrangement hole 424, the position of the liquid supply port 481 in the arrangement hole 424 is fixed.
The auxiliary member 59 is positioned between the tapered portion 53 and the sheet member 423 in the width direction (X direction) of the cartridge 4. The auxiliary member 59 is formed of a synthetic resin such as polypropylene or polystyrene. The auxiliary member 59 is disposed in the space between the tapered portion 53 and the sheet member 423, and accordingly, the movement of the tapered portion 53 in the case 40 is suppressed.
The cover member 425 is a sheet-like member attached to the surface of the case 40. The cover member 425 is formed with the direction identification section 428.
A-4. Positional Relationship of Each Element of Cartridge:
The corner 48 is formed at a position shifted to one side of the first side surface 405 side and the second side surface 406 side in the width direction (X direction) of the cartridge 4. In the present embodiment, the corner 48 is formed at a position shifted to the first side surface 405 side in the width direction of the cartridge 4. In other words, the corner 48 is formed at a position closer to the first side surface 405 than to the second side surface 406.
The circuit substrate 80 having the contact portion cp is disposed at a position shifted to one side of the first side surface 405 side and the second side surface 406 side in the width direction (X direction) of the cartridge 4. In the present embodiment, the circuit substrate 80 having the contact portion cp is disposed at a position shifted to the first side surface 405 side in the width direction of the cartridge 4. In other words, the circuit substrate 80 is disposed at a position closer to the first side surface 405 than to the second side surface 406, and is positioned between the first center plane PWP and the first side surface 405 in the width direction.
The first cartridge-side positioning hole 42 and the second cartridge-side positioning hole 44 are respectively disposed at positions shifted to the first side surface 405 side, which is one side, in the width direction of the cartridge 4. In other words, the first cartridge-side positioning hole 42 and the second cartridge-side positioning hole 44 are respectively disposed at a position closer to the first side surface 405 than to the second side surface 406, and are positioned between the first center plane PWP and the first side surface 405 in the width direction. Further, the first cartridge-side positioning hole 42 and the second cartridge-side positioning hole 44 are respectively positioned within a range WCP where the plurality of contact portions cp are positioned in the width direction of the cartridge 4.
The fluid receiving section 46 and the arrangement recessed portion 411 are respectively disposed at positions shifted to the first side surface 405 side, which is one side, in the width direction of the cartridge 4. In other words, the fluid receiving section 46 and the arrangement recessed portion 411 are respectively disposed at a position closer to the first side surface 405 than to the second side surface 406, and are positioned between the first center plane PWP and the first side surface 405 in the width direction. Further, the fluid receiving section 46 is positioned within the range WCP where the plurality of contact portions cp are positioned in the width direction of the cartridge 4.
The cartridge-side identification member 41 is disposed in a range including the center TP in the height direction (Z axis direction) of the cartridge 4 in which the top surface 402 and the bottom surface 403 oppose each other. In other words, the cartridge-side identification member 41 is disposed at a position passing through the second center plane PTP. Further, the cartridge-side identification member 41 is disposed at a position shifted to the first side surface 405 side which is one side. In the present embodiment, the cartridge-side identification member 41 is disposed being in contact with the first side surface 405. The cartridge-side identification member 41 is disposed on the side portion (in the present embodiment, the side portion on the first side surface 405 of the liquid supply port 481) of the liquid supply port 481 in the width direction. In other words, the cartridge identification member 41 is disposed such that at least a part thereof overlaps the range where the liquid supply port 481 is positioned in the height direction. In the present embodiment, in the height direction, the center of the cartridge-side identification member 41 and the center (center axis CT) of the liquid supply port 481 are disposed at the same position. Here, a case where the center of the cartridge-side identification member 41 and the center of the liquid supply port 481 are disposed at the same position with respect to the height direction means both a case where the center of the cartridge-side identification member 41 and the center of the liquid supply port 481 are positioned completely at the same position with respect to the height direction, and a case where the center of the cartridge-side identification member 41 is slightly deviated from the center of the liquid supply port 481 due to the tolerance or the like. In the height direction, the center of each of the liquid supply port 481 and the cartridge-side identification member 41 is positioned at the center of the mounting section 6.
According to the above-described first embodiment, in the width direction of the cartridge 4, the liquid supply port 481 is disposed at the center of the case 40, and the contact portion cp is disposed at a position shifted to the first side surface 405 side. Accordingly, for example, even when the liquid leaks from the liquid supply port 481 when a posture where the top surface 402 is a lower side is achieved during the transport of the cartridge 4, it is possible to reduce the possibility that the leaked liquid adheres to the contact portion cp. Accordingly, it is possible to suppress the contact failure between the contact portion cp and the apparatus-side terminal 72. In addition, for example, even when the posture where the bottom surface 403 is a lower side is achieved, the contact portion cp is disposed at a position shifted to the first side surface 405 side, and thus, the distance between the liquid supply port 481 and the contact portion cp can be ensured longer. Accordingly, even when the posture where the bottom surface 403 is a lower side is achieved, it is possible to reduce the possibility that the leaked liquid adheres to the contact portion cp. Accordingly, it is possible to suppress the contact failure between the contact portion cp and the apparatus-side terminal 72.
According to the first embodiment, the contact portion cp is disposed on the surface (inclined surface) 80fa inclined with respect to the mounting direction (−Y axis direction), and accordingly, it is possible to reduce the possibility that impurities such as dust adhere to the contact portion cp. In other words, when the cartridge 4 is inserted into the mounting section 6, the cartridge 4 advances in the −Y axis direction. At this time, the contact portion cp also advances in the −Y axis direction and gradually approaches the apparatus-side terminal 72, but does not come into contact with each other until immediately before the mounting is completed. Immediately before the mounting is completed, the apparatus-side terminal 72 and the cartridge-side terminal 830 slightly rub against each other. In this manner, while the apparatus-side terminal 72 and the cartridge-side terminal 830 hardly rub against each other when the cartridge 4 is mounted, it is possible to reduce the possibility that shavings (impurities) are generated as the apparatus-side terminal 72 rubs against the cartridge 4 when the cartridge 4 is mounted as the apparatus-side terminal 72 and the cartridge-side terminal 830 slightly rub against each other immediately before the mounting of the cartridge 4 is completed. Further, even when dust is present in the vicinity of the apparatus-side terminal 72 and is caught between the apparatus-side terminal 72 and the cartridge-side terminal 830, the dust can be removed as follows. In other words, the apparatus-side terminal 72 comes into contact with the surface 80fa of the cartridge-side terminal 830 while rubbing against the surface 80fa, an effect (wiping effect) of removing the dust from the contact portion cp is exhibited, and it is possible to reduce the possibility where the impurities such as dust are caught between the apparatus-side terminal 72 and the cartridge-side terminal 830. Accordingly, it is possible to suppress the contact failure between the contact portion cp and the apparatus-side terminal 72.
When the cartridge 4 is mounted on the mounting section 6, the positioning of the contact portion cp in the X axis direction, the Y axis direction, and the Z axis direction is performed by a positioning section different from the inclined surface 80fa. In other words, the positioning in the X axis direction and the Z axis direction is performed by the first cartridge-side positioning hole 42, and the positioning in the Y axis direction is performed by the cartridge-side engaging section 426. It is desirable to provide positioning sections in the X axis direction, the Y axis direction, and the Z axis direction on the inclined surface 80fa, for example, to provide the contact portions cp on both sides sandwiching the contact portions in the X axis direction in order to increase the positioning accuracy. However, in this case, there is a case where the dimension in the X axis direction increases. Accordingly, in order to reduce the size of the cartridge 4, according to the present embodiment, the positioning section is provided on a surface different from the inclined surface 80fa. In this case, it is particularly necessary to suppress the tolerance in the Y axis direction and the Z axis direction.
As illustrated in
According to the first embodiment, since the liquid storage bag 50 has the tapered portion 53 (
According to the above-described first embodiment, the first cartridge-side positioning hole 42, the second cartridge-side positioning hole 44, the fluid receiving section 46 are respectively disposed at positions shifted to the first side surface 405 side, which is one side, in the width direction of the cartridge 4. Accordingly, the displacement of the fluid receiving section 46 with respect to the mounting section 6 can be suppressed. Further, the arrangement recessed portion 411 in which the fluid receiving section 46 is disposed is disposed at a position shifted to the first side surface 405 side in the width direction of the cartridge 4. In other words, the arrangement recessed portion 411 can be provided by effectively using the space 40sp (
According to the above-described first embodiment, in the width direction of the cartridge 4, the first cartridge-side positioning hole 42, the second cartridge-side positioning hole 44, and the fluid receiving section 46 are positioned within the range WCP where the plurality of contact portions cp are positioned. Accordingly, the displacement of the fluid receiving section 46 and the contact portion cp in the mounted state of the cartridge 4 can be suppressed. Further, according to the above-described first embodiment, as the cartridge-side identification member 41 is disposed in the range including the center TP in the height direction of the cartridge 4, the rotation of the cartridge 4 with the center TP in the height direction as a fulcrum can be suppressed. Accordingly, during the mounting process of the cartridge 4, it is possible to reduce the possibility that the first apparatus-side positioning section 82 inserted into the first cartridge-side positioning hole 42 and the second apparatus-side positioning section 84 inserted into the second cartridge-side positioning section 44 collide with the cartridge 4 and an external force is applied. Further, according to the above-described first embodiment, the cartridge-side identification member 41 is disposed on the first side surface 405 side, which is one side, in the width direction, and is disposed on the side portion of the liquid supply port 481. Accordingly, since the distance between the liquid supply port 481 and the cartridge-side identification member 41 can be disposed closer, even when the cartridge 4 rotates around the vicinity of the cartridge-side identification member 41, the displacement of the liquid supply port 481 can be suppressed. Thereby, the displacement of the liquid supply port 481 during the mounting process can be suppressed.
According to the above-described first embodiment, the cartridge 4 can be accurately positioned by using the two first cartridge-side positioning holes 42 and the second cartridge-side positioning holes 44. Further, according to the above-described first embodiment, the cartridge-side engaging section 426 (
The substrate holder 880 is detachably attached to the corner 48a. The substrate holder 880 and the corner 48a have engaging sections (not illustrated) configured to be attachable to and detachable from each other. The substrate holder 880 has a holder inclined surface 88fa to which the circuit substrate 80 is attached. The holder inclined surface 88fa is inclined with respect to the mounting direction (−Y axis direction) of the cartridge 4a in a state where the substrate holder 880 is attached to the corner 48a. Specifically, the normal vector of the holder inclined surface 88fa has the +Z axis direction component and the −Y axis direction component. The corner 48a is positioned at a part where the front surface 401 and the top surface 402 intersect each other. The corner 48a has a recessed shape recessed inward of the case 40a. In a state where the substrate holder 880 is attached to the corner 48a, the surface 80fa is inclined with respect to the mounting direction, similar to the first embodiment. Even in this case, the same effect as that in the above-described first embodiment can be obtained. For example, even when the liquid leaks from the liquid supply port 481 when a posture where the top surface 402 is a lower side is achieved during the transport of the cartridge 4, it is possible to reduce the possibility that the leaked liquid adheres to the contact portion cp.
The corner 48a (
The circuit substrate 80 is attached to the bottom surface 988. Specifically, similar to the first embodiment, the surface 80fa of the circuit substrate 80 is disposed so as to be inclined in a direction including the −Y axis direction component and the +Z axis direction component.
Each of a pair of contact regulating sections 906t and 906w is provided on a pair of side walls 902t and 902w that oppose each other in the X axis direction of the corner 48b. The first contact regulating section 906t is formed in a shape such that a part of the first side wall 902t is dug down in the +X axis direction. In other words, the first contact regulating section 906t is sunk in the +X axis direction from the first side wall 902t. The first contact regulating section 906t extends along the Y axis direction. Specifically, the first contact regulating section 906t extends from the position of the opening 982 toward the back wall 986 side along the +Y axis direction. A first apparatus-side regulating section 756t (
The second side wall 902w is provided with the second contact regulating section 906w. The second contact regulating section 906w is formed in a shape such that a part of the second side wall 902w is dug down in the −X axis direction. In other words, the second contact regulating section 906w is sunk in the −X axis direction from the second side wall 902w. The second contact regulating section 906w extends along the Y axis direction. Specifically, the second contact regulating section 906w extends from the position of the opening 982 toward the rear wall 906 side along the +Y axis direction. A second apparatus-side regulating section 756w (
The apparatus-side terminal portion 70b (
Before contact between the apparatus-side terminal 72 and the cartridge-side terminal 830 is started, the first apparatus-side regulating section 756t starts to be inserted into the first contact regulating section 906t, and the second apparatus-side regulating section 756w starts to be inserted into the second contact regulating section 906w. Accordingly, the movement of the contact portion cp in the direction orthogonal to the mounting direction with respect to the apparatus-side terminal 72 is regulated, and the positioning of the contact portion cp and the apparatus-side terminal 72 is performed. Therefore, it is possible to excellently achieve the contact between the contact portion cp and the apparatus-side terminal 72.

The engagement mechanism 870 is disposed at a position where at least a part thereof overlaps the second apparatus-side positioning section 84 in the height direction (Z axis direction). In the present embodiment, the engagement mechanism 870 is positioned on the −X axis direction side of the second apparatus-side positioning section 84. The engagement mechanism 870 has a plate-like main body portion 8872 and a projection portion 871 that is provided at the distal end of the main body portion 872 and protrudes on the +Z axis direction side. The projection portion 871 side part of the main body portion 872 can be elastically deformed in the +Z axis direction with the base end portion of the main body portion 872 as a fulcrum. The projection portion 871 side part of the main body portion 872 is configured to be biased in the +X axis direction by a coil spring (not illustrated) by being displaced in the −X axis direction side. The projection portion 871 is a part that is engaged with the cartridge-side engaging section of the cartridge which will be described later.
The cartridge-side engagement mechanism 1600 (
As illustrated in
The receiving section 1601 extends from the front surface 401 to the back surface 404 side, and receives the projection portion 871 of the engagement mechanism 870. The receiving section 1601 has an opening 1605 formed on a first surface 45. The projection portion 871 is received in the receiving section 1601 through the opening 1605. The receiving section 1601 is deeper than the other parts 1606, 1608, 1612, and 1616 of the cartridge-side engagement mechanism 1600. Accordingly, while the projection portion 871 is positioned at the other parts 1606, 1608, 1612, and 1616, the projection portion 871 side of the main body portion 872 is pushed down. Accordingly, an external force is received in a direction (+Z axis direction) in which the cartridge 4K is pushed up through the projection portion 871 by the elastic force of the main body portion 872.
The guide section 1606 is a part for guiding the projection portion 871 of the engagement mechanism 870 to the engaging position St (the position where the cartridge-side engaging section 1612 is formed). The guide section 1606 is coupled to the receiving section 1601. The guide section 1606 extends in a direction inclined with respect to the mounting direction (−Y axis direction) of the cartridge 4K when the cartridge 4K is mounted on the mounting section 6K. Specifically, the guide section 1606 is inclined in the width direction of the cartridge 4K with respect to the mounting direction. The guide section 1606 has an inclined portion 1606a of which a groove becomes shallower as the distance from the receiving section 1601 increases. There is no step at the boundary between the guide section 1606 and the receiving section 1601.
The coupling section 1608 couples the guide section 1606 and the cartridge-side engaging section 1612 to each other. The coupling section 1608 has a projecting wall 1615 that protrudes to the −Y axis direction side from the wall on the +Y axis direction side that defines the groove. The cartridge-side engaging section 1612 opposes the projecting wall 1615. The cartridge-side engaging section 1612 has an engaging wall 614. The engaging wall 614 is formed by a wall portion 633 that is one of a plurality of wall portions that define the groove of the cartridge-side engagement mechanism 1600. The cartridge-side engaging section 1612 is formed at a position passing through a plane Cl. The outlet portion 1616 couples the cartridge-side engaging section 1612 and the receiving section 1601 to each other. The outlet portion 1616 has an inclined portion 1616a of which a groove becomes deeper as approaching the receiving section 1601. A step 620 is formed at the boundary between the outlet portion 1616 and the receiving section 1601.
Next, the movement of the projection portion 871 in the cartridge-side engagement mechanism 1600 during the operation of attaching and detaching the cartridge 4K will be described with reference to
When the pressing of the cartridge 4K in the mounting direction by the user is released, by the biasing force of the valve mechanism or the like in the liquid supply section 49, the cartridge 4K is slightly pushed back in the removing direction (+Y axis direction). Accordingly, the engagement by the projecting wall 1615 is released, and the projection portion 871 reaches the cartridge-side engaging section 1612. Finally, the projection portion 871 collides with the engaging wall 614 of the cartridge-side engaging section 1612. When the projection portion 871 collides with the engaging wall 614, a click sound is generated. By the click sound, the user can confirm that the cartridge 4K has reached the engaging position St and that the mounting of the mounting section 6K has been completed. As the projection portion 871 abuts against the engaging wall 614, the movement of the cartridge 4K in the removing direction is regulated.
When removing the cartridge 4K from the mounting section 6K, the following procedure is performed. First, the cartridge 4K in the mounted state is pushed in the mounting direction by the user. Accordingly, the projection portion 871 is separated from the engaging wall 614, and the engagement between the cartridge-side engagement mechanism 1600 and the engagement mechanism 870 is released. Next, by moving the cartridge 4K in the removing direction (+Y axis direction) by an external force by the user, an external force of the valve mechanism or the like of the liquid supply section 49, or the like, the projection portion 871 passes through the outlet portion 1616 and reaches the receiving section 1601. Then, the user grasps and removes the cartridge 4K from the mounting section 6K. The cartridge-side engagement mechanism 1600 may be provided on another surface such as the first side surface 405 or the second side surface 406, for example, instead of the bottom surface 403. In this case, the arrangement position of the engagement mechanism 870 is also changed according to the arrangement position of the cartridge-side engagement mechanism 1600.

The cartridge includes: a case including a front surface and a back surface opposing each other, a top surface and a bottom surface intersecting the front surface and the back surface and opposing each other, and a first side surface and a second side surface intersecting the front surface, the back surface, the top surface, and the bottom surface and opposing each other; an inclined surface in which the front surface side is positioned closer to the bottom surface side than the back surface side, and which is inclined with respect to a mounting direction of the cartridge that is a direction from the back surface toward the front surface, the inclined surface being disposed at a recessed corner where the front surface and the top surface intersect each other and which is recessed inward of the case; a plurality of contact portions that are disposed on the inclined surface and are in contact with an apparatus-side terminal portion of the liquid ejecting apparatus; a cartridge-side positioning hole that is formed on the front surface for positioning the cartridge by inserting an apparatus-side positioning section of the liquid ejecting apparatus; and a cartridge-side engaging section that is formed on the top surface and engaged with an apparatus-side engaging section of the liquid ejecting apparatus, the plurality of contact portions are formed in a plurality of rows, and when a direction in which the first side surface and the second side surface oppose each other is an X axis direction, a direction in which the front surface and the back surface oppose each other is a Y axis direction, and a direction in which the top surface and the bottom surface oppose each other is a Z axis direction, the cartridge-side engaging section has an engaging surface parallel to the X axis direction and the Z axis direction, the engaging surface and the cartridge-side positioning hole intersect an imaginary plane, and the imaginary plane is a plane that passes through the contact portion positioned at the center in the X axis direction among the plurality of contact portions formed in a row closest to the cartridge-side positioning hole among the plurality of rows, and is parallel to the Y axis direction and the Z axis direction. According to the aspect, the distance from the contact portion positioned at the center in the X axis direction to each of the engaging surface and the first cartridge-side positioning hole can be shortened. Accordingly, the positioning accuracy of the cartridge with respect to the liquid ejecting apparatus performed by the engaging surface and the first cartridge-side positioning hole can be improved.
(11) According to another aspect of the present disclosure, there is provided a liquid ejecting apparatus having the cartridge described in any one of the above-described aspects mounted thereon. According to the aspect, even when the liquid leaks from the liquid supply port, it is possible to reduce the possibility that the leaked liquid adheres to the contact portion. Accordingly, it is possible to suppress the contact failure between the contact portion and the apparatus-side terminal.
The present disclosure can be realized in various forms, and can be realized in a form of a cartridge manufacturing method, a liquid ejection system including a cartridge and a liquid ejecting apparatus, and the like, in addition to the cartridge.
The present application is based on, and claims priority from JP Application Serial Number 2017-222387, filed Nov. 20, 2017, the disclosure of which is hereby incorporated by reference herein in its entirety.
