A-3. Schematic description of the internal configuration of the cartridge and the mounting state of the cartridge:
9, an internal configuration of the first cartridge 10 and the second cartridge 20 and an outline of a mounting state of the first cartridge 10 and the second cartridge 20 to the cartridge holder 60 will be described with reference to FIG. FIG. 10 is a sectional view taken along line 10-10 of FIG. Note that part of FIG. 10 is schematically illustrated.

  As shown in FIG. 9, when the first cartridge 10 is mounted on the cartridge holder 60, the fourth liquid supply needle 640D is inserted into the first liquid supply port 180 of the first cartridge 10. Accordingly, black ink is supplied from the first liquid storage chamber 100 to the head 540 via the fourth liquid supply needle 640D. The first liquid storage chamber 100 does not have a liquid absorber for absorbing and holding a liquid. That is, the first cartridge 10 is a direct liquid type cartridge. In the first liquid storage chamber 100, a valve mechanism 150 for opening and closing a flow path connecting the first liquid storage chamber 100 and the liquid supply port 180 is arranged. The valve mechanism 150 has, for example, a configuration similar to that of the valve disclosed in JP2013-248786A. Specifically, the valve mechanism 150 has a valve body 152 that closes the communication hole 142. The communication hole 142 and the valve body 152 are provided in the middle of the flow path connecting the first liquid storage chamber 100 and the liquid supply port 180. Since the ink flows from the first liquid storage chamber 100 toward the liquid supply port 180, the liquid supply port 180 side is the downstream side. The flow path connecting the first liquid storage chamber 100 and the liquid supply port 180 is normally closed by the valve body 152 receiving the urging force of the urging member 155 to close the communication hole 142. . In this state, when the liquid downstream of the valve 152 is consumed and the negative pressure downstream of the valve 152 reaches a predetermined magnitude, the valve 152 responds to the urging force of the urging member 155. In opposition to this, it is displaced away from the communication hole 142. When the valve body 152 moves away from the communication hole 142, the liquid is supplied from the upstream portion to the downstream portion of the valve body 152 via the communication hole 142. When a predetermined amount of liquid is supplied to a portion downstream of the valve body 152 and reaches a predetermined pressure (negative pressure), the valve body 152 is displaced so as to close the communication hole 142 by the urging force of the urging member 155. I do. The first liquid storage chamber 100 communicates with the atmosphere, and the air is introduced into the first liquid storage chamber 100 as the liquid is consumed.

  When the second cartridge 20 is mounted on the cartridge holder 60, the corresponding liquid supply needle 640 is inserted into the liquid supply port 280 of the second cartridge 20. Thus, yellow ink, magenta ink, and cyan ink are supplied from the second liquid storage chamber 200 to the head 540 via the liquid supply needle 640. The second cartridge 20 has three second liquid storage chambers 200 that respectively store three types of liquids. When the three second liquid storage chambers 200 are used separately, a second liquid storage chamber 200A, a second liquid storage chamber 200B, and a second liquid storage chamber 200C are used. The three second liquid storage chambers 200 </ b> A to 200 </ b> C are partitioned by partition walls 22 and 23 so that the liquids do not mix with each other. The second liquid storage chamber 200A stores yellow ink, the second liquid storage chamber 200B stores magenta ink, and the second liquid storage chamber 200C stores cyan ink. Each of the three second liquid storage chambers 200A to 200C stores a liquid absorber 299 that absorbs and holds a liquid. The liquid absorber 299 is a member for holding a liquid by a predetermined capillary force, and may be a foamable member such as urethane foam, or a fiber member obtained by bundling polypropylene processed into a fibrous shape. . Each of the liquid absorbers 299 is arranged in substantially the entire area of each of the liquid storage chambers 200A to 200C. Unlike the first liquid storage chamber 100, the valve mechanism 150 is not provided in the second liquid storage chamber 200A to the second liquid storage chamber 200C. In the second cartridge 20, since the negative pressure in the liquid storage chambers 200A to 200C is maintained by the capillary force of the liquid absorber 299, the valve mechanism 150 is unnecessary. Each of the second liquid storage chambers 200A to 200C has an upstream portion communicating with the atmosphere, and the air is introduced into the second liquid storage chambers 200A to 200C as the liquid is consumed. You.

  A valve mechanism 284 is disposed inside each of the liquid supply ports 180, 280A to 280C. As shown in FIG. 10, the valve mechanism 284 opens and closes the internal flow paths of the liquid supply ports 180 and 280. The valve mechanism 284 includes a seal portion (valve seat) 287, a valve body 286, and a biasing member 285 in order from the distal end side of the liquid supply ports 180 and 280. The seal portion 287 is a substantially annular member. The seal portion 287 is made of, for example, an elastic body such as rubber or an elastomer. The seal portion 287 is press-fitted into the liquid supply ports 180 and 280. The seal portion 287, in the mounted state, comes into contact with the outer peripheral surface of the liquid supply needle 640 in an airtight manner, thereby suppressing leakage of the liquid to the outside from the gap between the liquid supply ports 180, 280 and the liquid supply needle 640. The valve body 286 is a substantially columnar member. The valve body 286 is urged by the urging member 285 in a direction toward the seal portion 287 in a state before the cartridges 10 and 20 are mounted on the cartridge holder 60 (unmounted state), and is formed on the seal portion 287. The hole is closed. That is, in the unmounted state, the valve mechanism 284 is in the closed state. The biasing member 285 is a compression coil spring. In the mounted state of the cartridges 10 and 20, the liquid supply needle 640 pushes the valve 286 in a direction away from the seal 287, so that the valve 286 is separated from the seal 287. As a result, the valve mechanism 284 is opened.

  As shown in FIG. 10, when the second cartridge 20 is mounted, the engagement member 230 of the second cartridge 20 is locked on the lower surface 633 of the device-side engagement portion 632A. The surface 633 is a surface facing the −Z direction. The engagement member 230 is a member operated by a user to attach and detach the second cartridge 20 to and from the second mounting portion 602T, and is an elastic lever. The engagement member 230 has a cartridge-side engagement portion 235 locked to the surface 633.

The first surface 201A is provided with a liquid supply port 280 through which the liquid inside flows out.

  The other side liquid container 20C has a first surface 201C to a sixth surface 206C forming an outer shell 21C. The shape of the other-side liquid container 20C is the same as the shape of the one-side liquid container 20A, and a description thereof will be omitted.

  The second type liquid container 20B has a first surface 201B to a sixth surface 206B forming an outer shell 21B. Each of the surfaces 201B to 206B has a planar shape. The term “flat” includes a case where the entire surface is completely flat and a case where a part of the surface has irregularities. The first surface 201B forms a bottom surface, the second surface 202B forms a top surface, the third surface 203B forms a back surface, the fourth surface 204B forms a front surface, and the fifth surface 205B forms a left side surface. , The sixth surface 206B constitutes the right side surface.

The protruding portion 245B is a portion that protrudes in the −Y direction from the connection surface 209 that is a flat surface facing the fourth surface 204B in the Y direction. Due to the protrusion 245B, the distance D2 between the first side surface 203B and the second side surface 204B of the second type liquid container 20B in the Y direction is equal to the distance between the first side surfaces 203A and 203C of the first type liquid container 20A and 20C. It is larger than the distance D1 between the second side surfaces 204A and 204C. Note that the protrusion 245B may be formed from the first surface 201B side to the second surface 202B side in the Z direction. In addition, one of the first type liquid containers 20A and 20C and the second type liquid container 20B may have an engagement member 230 shown in FIG. Even in the case where there is no engagement member 230, the first type liquid containers 20A and 20C are caused by friction between the mounting portion 602 and the first type liquid containers 20A and 20C and the second type liquid containers 20B. The mounting state of the mounting section 602 of the second type liquid container 20B can be maintained.

  The storage device 420 of the circuit board 400 stores information on two or more liquid containers, that is, the first type liquid containers 20A and 20C and the second type liquid container 20B in this embodiment. This information includes, for example, information indicating the type of liquid to be stored, information indicating the amount of liquid to be stored, and the amount of liquid consumed in each of the first type liquid containers 20A and 20C and the second type liquid container 20B. , Date of manufacture, and information indicating the expiration date.

  As shown in FIG. 26, in a state where the second type liquid container 20B is mounted on the second mounting portion 602T, the circuit board 400 is disposed in the second recess 75A. That is, the circuit board 400 is arranged in the second concave portion 75A by disposing the circuit board 400 on the surface 203B on the −Y direction side of the protruding portion 245B. Accordingly, in the mounted state, the movement of the second circuit board 400 in the X direction can be restricted, so that a change in the position of the contact portion cp can be suppressed. Therefore, good contact between the contact portion cp and the second device-side terminal group 799A can be maintained.

  The exchange of information between the storage device 420 and the control unit 510 shown in FIG. 1 in the second embodiment will be described below. The liquid amount of any of the three liquid containers 20A, 20B, and 20C becomes zero or close to zero, and the liquid container in which the liquid amount becomes zero or close to zero is removed from the mounting unit 602, and a new liquid container is placed. When the device is attached, the following information is exchanged. For example, a case where the liquid container 20A in which the liquid has been consumed is removed and a new liquid container 20A is mounted on the mounting portion 602 will be described below. Here, the liquid container 20A in which the liquid has been consumed is also referred to as an old liquid container 20A1, and the new liquid container 20A is also referred to as a new liquid container 20A2.

  First, when the new liquid container 20A2 is mounted on the mounting unit 602, the information regarding the old liquid container 20A1 stored in the storage device 420, for example, the liquid consumption is reset. This reset may be executed by the control unit 510, for example, when the user inputs a reset instruction to the control unit 510 via a button or a touch panel that receives an input of the liquid ejecting apparatus 50. This reset may be executed by, for example, transmitting a reset signal from the new liquid container 20A2 to the storage device 420. When transmitting a reset signal from the new liquid container 20A2, the new liquid container 20A2 has a circuit that transmits a reset signal that is electrically connected to the storage device 420 in the mounted state. Next, control unit 510 measures the liquid consumption of new liquid container 20A2. The measurement of the liquid consumption is performed by counting the number of droplets of the new liquid container 20A2 ejected from the head 540 and measuring the amount of liquid supplied to the head 540. The control unit 510 reads the liquid storage amount stored in the new liquid container 20A2 stored in the storage device 420 at a predetermined timing, and subtracts the measured liquid consumption amount from the read liquid amount. Calculate the current liquid amount. Then, control unit 510 writes the calculated liquid storage amount in storage device 420. When the liquid storage amount falls below a predetermined threshold, control unit 510 notifies the user of the replacement of the liquid container whose liquid storage amount has fallen below the threshold, for example, a new liquid container 20A2. This notification is performed, for example, by displaying on the monitor of the liquid ejecting apparatus 50 or a monitor electrically connected to the liquid ejecting apparatus 50 a message urging replacement.

  The control unit 510 may read out and store the information on the first type liquid containers 20A and 20C stored in the storage device 420 at a predetermined timing. By doing so, when the second type liquid container 20B having the storage device 420 is removed and a new second type liquid container 20B is mounted on the mounting portion 602, the following processing can be executed. That is, the control unit 510 can write information on the first type liquid containers 20A and 20C mounted on the mounting unit 602 into the storage device 420 of the new second type liquid container 20. The information on the new second type liquid container 20B is stored in the storage device 420 of the new second type liquid container 20B in advance.

  According to the second embodiment, since the two or more liquid containers 20A, 20B, and 20C are separately formed, each of the two or more liquid containers 20A, 20B, and 20C is independently provided with a new liquid. Can be replaced with a container. Thus, the liquid in the liquid container set 20a can be effectively used. This also makes it possible to suppress a decrease in the versatility of the individual liquid containers 20A, 20B, and 20C.

That is, the liquid container 20Ba has the outer shell 21Ba having a substantially rectangular parallelepiped shape. The liquid container 20Ba stores magenta ink.

  The liquid container 20Ba does not have the second circuit board 400 on the first side surface 203B1, which is a part of the outer shell 21Ba, and the first side surface 203A as the third surface of the other liquid containers 20A and 20C. , 203C. In the Y direction, the distance D2a between the first side surface 203B1 and the second side surface 204B is the same as the distance D1 between the first side surfaces 203A and 203C and the second side surfaces 204A and 204C.

  As shown in FIG. 28, when the liquid container set 20b is mounted on the second mounting portion 602T, the three liquid containers 20A, 20Ba, and 20C are arranged in the X direction with respect to the mounting portion 602. The adapter 245Ba is arranged on the third surface 203A, 203B1, 203C side located on the −Y direction side. Further, the circuit board 400 of the adapter 245Ba mounted on the liquid container 20Ba is disposed in the second recess 75A when mounted on the second mounting portion 602T. Accordingly, in the mounted state, the movement of the second circuit board 400 in the X direction can be restricted, so that a change in the position of the contact portion cp can be suppressed. Therefore, good contact between the contact portion cp of the second circuit board 400 and the device side terminal group 799A can be maintained.

  According to the third embodiment, since the two or more liquid containers 20A, 20Ba, and 20C are separately formed, each of the two or more liquid containers 20A, 20Ba, and 20C is independently provided with a new liquid. Can be replaced with a container. Thereby, the liquid in the liquid container set 20b can be effectively used. Further, since the adapter 245Ba is configured to be detachable from each of the liquid containers 20A, 20Ba, and 20C, each of the liquid containers 20A, 20Ba, and 20C serves as a liquid container that stores the magenta ink located at the center. It can be used, and a decrease in versatility can be suppressed.
