[0053] As described in the background art, an image forming apparatus includes an ink cartridge and a printing device, and when the ink cartridge is inserted into the printing device, the ink cartridge chip may not be grounded or the grounding may be unstable, which may affect the stability of the chip grounding and safety of use. Through research by the inventor, the cause of this problem has been found to be as follows:

[0054] When installing an ink cartridge, the contact pins of the printing device are exposed inside the installation section. If an ink cartridge or a foreign object accidentally falls into the installation section and hits the ground contact pins, the ground contact pins may bend unexpectedly, or the contact points may be damaged by friction or become unstable. This may prevent stable contact with the ground terminal of the chip, resulting in the chip not being able to be grounded or the grounding being unstable. Therefore, if excessive current flows through the ink cartridge, there is a risk of damaging the chip and the printing device, and the printing device may not be able to correctly identify the ink cartridge.

[0055] In response to the above technical problem, an ink cartridge according to an embodiment of the present application includes a conductive member and a chip, and the ground terminal of the chip is electrically connected to the conductive member, which is then electrically connected to a ground member located within the mounting chamber of the printing device. With this configuration, when the ink cartridge is inserted into the printing device, the chip is electrically connected to the ground member via its ground terminal and the conductive member. This ensures that the chip is stably grounded.

[0056] By configuring the ink cartridge in this manner, the ground terminal of the chip is connected to the ground member via a conductive member, thereby preventing situations in which the chip cannot be grounded or the ground becomes unstable due to unstable contact between the ground terminal and the ground contact pin. This improves the reliability of the chip ground, prevents damage to the chip and printing device due to excessive current, improves the safety of using the ink cartridge and printing device, and reduces the occurrence of situations in which the printing device is unable to identify the ink cartridge.

[0057] In order to make the above-mentioned objects, features, and advantages of the embodiments of the present application clearer and easier to understand, the present invention according to the embodiments of the present application will be clearly and completely described below based on the drawings of the embodiments of the present application. Of course, the described embodiments are only some of the embodiments of the present application, and do not represent all of the embodiments. Other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative effort are all within the technical scope of the present invention.

[0058] 1 to 3, an ink cartridge 10 according to an embodiment of the present application is one of the consumable parts of a printing device. Consumable parts include, but are not limited to, ink cartridges 10 and may be, for example, toner cartridges, ribbons, etc., and the embodiment of the present application will be described using an ink cartridge as an example.

[0059] Since the ink cartridge 10 must be replaced when the ink runs out, the ink cartridge 10 is typically removably mounted in a printing device. For example, the printing device in the embodiment of this application is also referred to as a printer, and the printer has a mounting chamber, which includes a mounting section 90 that houses the ink cartridge and a grounding member for grounding the printer (also referred to as the printing device). The ink cartridge is inserted into the mounting section and is electrically connected to the mounting section of the printer to establish communication between the ink cartridge and the printer.

[0060] Specifically, the printing device has a mounting chamber, and the mounting section is provided within the mounting chamber. The mounting section includes a storage chamber and a contact pin assembly, and the grounding member is provided at a position other than the position where the contact pin assembly is provided. At least one ink cartridge is inserted into the storage chamber. At least a portion of the contact pin assembly is exposed within the storage chamber and is electrically connected to a chip of the ink cartridge. The grounding member and the contact pin assembly are two different members. In other words, the grounding member does not belong to the contact pin assembly.

[0061] The ink cartridge is removably mounted in the printing device. The printing device has a mounting portion and a grounding member provided within the mounting chamber. The mounting portion includes a storage chamber and a contact pin assembly. The grounding member is provided at a position other than the position where the contact pin assembly is provided. The ink cartridge includes an ink cartridge body, a chip, and a conductive member. The chip is provided in the ink cartridge body. At least a portion of the ink cartridge body and the chip can be located within the storage chamber. The chip is provided with a communication terminal group and a grounding terminal, and the communication terminal group is electrically connected to the contact pin assembly. The conductive member is provided within the mounting chamber. The conductive member is configured to electrically connect the grounding terminal and the grounding member.

[0062] The contact pins of the contact pin assembly are deformable, and the ground member is non-deformable. When the chip contacts the contact pins, at least one contact pin is deformed. When the conductive member contacts the ground member, the ground member is not deformed. Since the contact surface deforms when two objects contact each other, it should be noted that in this embodiment, the "non-deformable" ground member refers to the minute deformation that occurs when the ground member and the conductive member contact each other, which is generally not visible to the naked eye, compared to the large deformation of the contact pin.

[0063] The ink cartridge 10 comprises an ink cartridge body 50 for storing ink, a chip 20 provided on the surface of the ink cartridge body 50, and a conductive member. The chip 20 is used to store information such as ink cartridge manufacturer information, ink volume information, ink cartridge type information, and ink color. The chip is provided with a plurality of terminals. Depending on the terminal's purpose, the plurality of terminals are divided into communication terminals and ground terminals; that is, the chip is provided with a group of communication terminals and a ground terminal, and the group of communication terminals includes a plurality of communication terminals.

[0064] The communication terminal is configured to contact and be electrically connected to each contact pin of the contact pin assembly. The ground terminal is connected to one end of the conductive member, and the other end of the conductive member can be connected to the ground member. Thus, the ground signal of the chip can be transmitted to the ground member through the conductive member to complete the grounding.

[0065] When the ink cartridge 10 is inserted into the containing chamber, each communication terminal of the chip 20 contacts and electrically connects with the corresponding contact pin assembly, thereby transmitting, verifying, exchanging data, etc. between the ink cartridge 10 and the printer. At the same time, the conductive member is electrically connected to the grounding member, thereby grounding both the ink cartridge and the printer.

[0066] Compared to related art in which the ground terminal of the chip 20 is electrically connected to the corresponding ground contact pin of the contact pin assembly, the ink cartridge of the present application connects the ground terminal of the chip to the ground member via a conductive member, thereby avoiding situations in which the chip cannot be grounded or the ground becomes unstable due to unstable contact between the ground terminal and the ground contact pin. This improves the reliability of the chip ground, prevents damage to the chip and the printing device due to excessive current, improves the safety of the chip and the printing device, and reduces the occurrence of situations in which the printing device cannot identify the ink cartridge.

[0067] Based on the above-described embodiments, the mounting portion of the present invention may be fixed within the mounting chamber or movably mounted within the mounting chamber. For example, the mounting portion may be slidably mounted within the mounting chamber. However, because the mounting portion is arranged differently within the mounting chamber, the mounting method of the ink cartridge to the mounting portion is affected, and the arrangement of the chip on the ink cartridge and the electrical connection method between the conductive member and the grounding member are also different. This will be described in detail in the present invention using different embodiments.

[0068] Embodiment 1 In the embodiment of the present application, the mounting portion is provided in the mounting chamber, and the grounding member is provided in the accommodation chamber of the mounting portion. Specifically, the mounting portion is movably provided in the mounting chamber.

[0069] Example 1 of Embodiment 1 In the first embodiment, an antenna-type conductive member is provided. The metal member provided in the mounting chamber is configured as a ground member, i.e., the metal member is grounded. One end of the conductive member is electrically connected to the ground terminal of the chip 20, and the other end is connected to the ground member, and the electrical connection point between the two is above the chip.

[0070] Referring to Figure 3, the mounting section is a component of the printing device and is used to mount one or more ink cartridges, and the ink cartridges are removably mounted in the mounting section along a mounting direction P. When an ink cartridge runs out, it must be replaced with a new ink cartridge.

[0071] The ink cartridge 10 includes a tip 20, a handle 30, an ink outlet 41, and an ink cartridge body 50. The mounting portion 90 includes a contact pin assembly 91, an ink supply portion 92, an opening 95, and a bottom wall 90a. The ink cartridge 10 is mounted into the mounting portion 90 through the opening 95 along a mounting direction P (-Z axis direction). The handle 30 is used to fix the ink cartridge 10 to the mounting portion 90 and prevent the ink cartridge 10 from being removed from the mounting portion 90.

[0072] Ink is stored in the case 50 (also referred to as the ink cartridge body 50), and the ink arrives at the ink supply unit 92 through the ink outlet 41, so that the ink supply unit 92 can provide ink to the printer's print head to perform the printing operation.

[0073] 4, the contact pin assembly 91 includes contact pins 91a and a base portion 910. The contact pins 91a are provided on the base portion 910. The chip 20 is provided with a group of communication terminals. The group of communication terminals can be in contact with and electrically connected to the contact pins of the contact pin assembly, and are used to transmit electrical signals.

[0074] In this embodiment, a three-dimensional Cartesian coordinate system, i.e., an XYZ coordinate system, is set. The three-dimensional Cartesian coordinate system of the ink cartridge coincides with the three-dimensional Cartesian coordinate system of the mounting portion. If the direction in which the ink cartridge 10 is inserted into the mounting portion is the -Z axis direction, the direction in which the ink cartridge is removed from the mounting portion is the +Z axis direction, with the opening 95 located in the +Z axis direction and the bottom wall 90a located in the -Z axis direction. Typically, a printer is placed flat on an office desk or printing press stand, with the opening 95 located at the top of the mounting portion 90 and the bottom wall 90a located at the bottom of the mounting portion 90. This arrangement makes it easy for users to insert and remove the ink cartridge.

[0075] Furthermore, the mounting section 90 can accommodate one or more ink cartridges. The mounting section has one or more mounting positions. For example, the mounting section 90 has four mounting positions, and each mounting position can accommodate one ink cartridge. The four ink cartridges can store inks of four different colors (e.g., black, yellow, cyan, and magenta).

[0076] The mounting portion according to this embodiment is a component having a substantially rectangular or cuboid shape and an opening. The inner wall and bottom wall 90a of the mounting portion form mounting positions. The contact pin assemblies 91 are attached to a first side wall 90c of the mounting portion, and the mounting positions are arranged sequentially in the Y-axis direction, with the four mounting positions arranged sequentially in the Y-axis direction. The direction perpendicular to the Y-axis and Z-axis is the X-axis direction, and the direction from the inside of the mounting portion 90 toward the contact pin assemblies 91 is the +X-axis direction. The +X-axis is perpendicular to the first side wall 90c, and when viewed along the +X-axis direction, if the +Z-axis is positioned upward on the YZ plane, the +Y-axis direction is positioned to the left.

[0077] Referring to FIG. 4, the contact pin assembly 91 includes a base 910 and a plurality of contact pins provided on the base 910. For example, the base 910 includes five contact pins, each of which is a first contact pin 911 through a fifth contact pin 915. Each contact pin is a thin metal piece that is conductive and wear-resistant. The base 910 also includes a plurality of slits 981 through 985 corresponding to the contact pins. Here, the slits 981, 982, 983, 984, and 985 correspond to the contact pins 911, 912, 913, 914, and 915, respectively. Each of the slits 981 through 985 is U-shaped and has a slit opening in the +Z-axis direction. The contact pins 911 through 915 are attached to the slits 981 through 985 along the -Z-axis direction, passing through the slit openings.

[0078] Specifically, the first contact pin 911 is attached to the first slit 981 through the slit opening along the -Z axis direction. The attachment method for the second contact pin 912 to the fifth contact pin 915 is similar to that for the first contact pin 911, so a description thereof will be omitted here. One side of each of the first contact pin 911 to the fifth contact pin 915 is connected to the main circuit of the printer via the internal circuit of the mounting portion, and the other side is exposed within the storage chamber of the mounting portion 90, and can be electrically connected to each communication terminal of the chip 20 when an ink cartridge is inserted into the storage chamber.

[0079] The first contact pin 911 to the fifth contact pin 915 in the embodiment of the present application have the same structure. In this embodiment, the structure of each contact pin will be described using the first contact pin 911 as an example. As shown in FIG. 5, the first contact pin 911 is divided into a first portion 911a, a second portion 911b, and a third portion 911c. The first portion 911a is electrically connected to a communication terminal of the chip 20 and is used to form a first contact portion. The second portion 911b is connected to an internal circuit of the printer.

[0080] The third portion 911c is connected to the first portion 911a and the second portion 911b. The third portion 911c is located in the +Z-axis direction of the first contact pin 911. The first contact pin 911 is fixed to the first slit 981 by the third portion 911c or a portion of the third portion 911c (for example, the horizontal portion 911h of the third portion 911c). The first portion 911a and the second portion 911b are provided at the end of the first contact pin 911 in the -Z-axis direction. This allows the first portion 911a and the second portion 911b to be elastically deformed and to easily return to their original state after deformation. The first portion 911a of the first contact pin 911 is provided in the -X-axis direction, and the second portion 911b is provided in the +X-axis direction. The first portion 911a and the second portion 911b protrude from the base portion 910, and the third portion 911c does not protrude from the base portion 910.

[0081] Furthermore, the first portion 911a and the second portion 911b protrude from the base portion 910 in the X-axis direction, and the base portion 910 is located between the first portion 911a and the second portion 911b. The first portion 911a is closer to the mounting position than the second portion 911b. That is, the first portion 911a can be electrically connected to the chip 20.

[0082] The third portion 911c has a first vertical portion 911k and a second vertical portion 911j that are perpendicular to the X-axis direction, and a horizontal portion 911h that is parallel to the X-axis direction. The horizontal portion 911h connects the first vertical portion 911k and the second vertical portion 911j. The first vertical portion 911k and the second vertical portion 911j extend up and down along the Z-axis direction. The first vertical portion 911k is closer to the mounting position than the second vertical portion 911j. The end of the first vertical portion 911k is connected to the first portion 911a, and the end of the second vertical portion 911j is connected to the second portion 911b. The horizontal portion 911h, the first vertical portion 911k, or the second vertical portion 911j is fixed to the first slit 981 in the +Z-axis direction.

[0083] 5, the first portion 911a includes a first surface portion 911a1, a second surface portion 911a2, a third surface portion 911a3, and a fourth surface portion (not shown). The third surface portion 911a3 is provided to face the fourth surface portion along the X direction. The region surrounded by the first surface portion 911a1 and the second surface portion 911a2 forms a protruding region, and the first vertical portion 911k is a vertical region. The second portion 911b is another protruding region, and the second vertical portion 911j is another vertical region. The second contact pin 912 to the fifth contact pin 915 have the same arrangement and structure as the first contact pin 911, and therefore their description will be omitted.

[0084] 6 and 7, chip 20 according to this embodiment has memory 100, substrate 120, and a plurality of terminals 130 (communication terminal group). Substrate 120 has front surface 120a, rear surface 120b, left surface 120c, right surface 120d, top surface 120e (not shown), and bottom surface 120f.

[0085] Here, front surface 120a faces rear surface 120b, and front surface 120a is located closer to the +X axis than rear surface 120b. Left surface 120c faces right surface 120d, and left surface 120c is located closer to the -Y axis than right surface 120d. Top surface 120e faces bottom surface 120f, and top surface 120e is located closer to the +Z axis than bottom surface 120f.

[0086] Furthermore, because a plurality of terminals 130 are provided on the front surface 120a, the front surface 120a is also referred to as a first terminal surface. For example, a first terminal 131, a second terminal 132, a third terminal 133, and a fourth terminal 134 are provided on the front surface 120a. The first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 are located at different positions on the Y axis, the first terminal 131 and the fourth terminal 134 are located at the same position on the Z axis, the second terminal 132 and the third terminal 133 are located at the same position on the Z axis, and the first terminal 131 and the third terminal 133 are located at different positions on the Z axis.

[0087] Furthermore, the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 are each configured as a communication terminal. The first terminal 131 (data terminal) is configured to transmit or receive a data signal. The second terminal 132 (clock terminal) is configured as a clock terminal for receiving a clock signal. The third terminal 133 (power terminal) is configured to provide an operating voltage to the memory 100. The fourth terminal 134 (reset terminal) is used to reset the data inside the memory 100.

[0088] Each communication terminal has one contact portion C, which is indicated by a circle. The multiple communication terminals have multiple contact portions C, which are first contact portion C1 to fourth contact portion C4. Contact portion C is the area of ​​terminal 130 that is most likely to come into contact with the contact pin when ink cartridge 10 is installed in the printer.

[0089] The communication terminal group includes a data terminal (first terminal 131), a reset terminal (fourth terminal 134), a power terminal (third terminal 133), and a clock terminal (second terminal 132). Contact portions C1 to C4 of the communication terminal group that come into contact with the contact pin assembly of each terminal are arranged in two rows along the mounting direction P in which the ink cartridge 10 is mounted to the printing device.

[0090] In the mounting direction P (i.e., the Z-axis direction shown), the contact portion C1 of the data terminal and the contact portion C4 of the reset terminal are provided on the upstream side, and the contact portion C3 of the power terminal and the contact portion C2 of the clock terminal are provided on the downstream side.

[0091] In the embodiment of the present application, the memory 100 and the communication terminal are both provided on the substrate 120. The memory 100 needs to be grounded and can be considered a "ground terminal." The memory 100 needs to transmit ground signals and interact with the printing device to ensure that the ink cartridge is properly installed in the printing device and the corresponding job is executed.

[0092] It should be noted that the memory 100 is used to store information such as manufacturer information, ink amount information, ink cartridge type information, ink color, etc. When the ink cartridge 10 is installed in the printer's installation section, data transmission, confirmation, data interaction, etc. are performed between the memory 100 and the printer, and the connection between the two is realized by connecting the communication terminals to the respective contact pins of the printer.

[0093] Furthermore, the memory 100 may be provided on any one or several of the surfaces from the front surface 120a to the bottom surface 120f. The memory 100 is preferably provided on the rear surface 120b. The specific shape and structure of the substrate 120 are not limited and can be determined by those skilled in the art according to specific design needs. The chip 20 may have, for example, a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure.

[0094] The placement position of memory 100 on substrate 120 is not limited, and for example, memory 100 may be provided at the rear end side close to the -Z axis direction of chip 20, or memory 100 may be provided at the front end side close to the +Z axis direction of chip 20, or memory 100 may be provided in the center of chip 20.A person skilled in the art will be able to provide memory 100 according to the specific design needs, so explanation will be omitted here.

[0095] 6, in this embodiment, the memory 100 is provided on the rear surface 120b, near the right surface 120d and the top surface 120e. The connection member 135 (also referred to as a conductive member) is made of a conductive material with a certain hardness and is connected to the conductive piece 135a (also referred to as a ground terminal) by solder. The conductive piece 135a (also referred to as a ground terminal) is connected to the memory 100 via a circuit / conductor built into the substrate 120. This connects the connection member 135 and the memory 100.

[0096] The conductive piece 135a (also referred to as a ground terminal) may be considered to be a part of the chip 20. Specifically, the conductive piece 135a (also referred to as a ground terminal) may be a copper coating (realized by electroplating technology) on the chip 20, and can electrically connect the conductive member 135 and the memory 100. The contact form between the connection member 135 (also referred to as a conductive member) and the conductive piece 135a (also referred to as a ground terminal) may be welding, abutting, or any other form as long as they can be electrically connected.

[0097] A connecting member 135 (also referred to as a conductive member) is provided within the mounting chamber. The connecting member 135 is configured to electrically connect a conductive piece 135a (also referred to as a ground terminal) and the ground member. Furthermore, a ground signal is transmitted between the ink cartridge 10 and the printing device via the ground terminal 135a, the conductive member 135, and the ground member. Optionally, a ground signal is transmitted between the ink cartridge 10 and the printing device via the memory 100 on the chip, the conductive member 135, and the ground member. Furthermore, a ground signal is transmitted between the ink cartridge 10 and the printing device via the memory 100 on the chip, the ground terminal 135a, the conductive member 135, and the ground member.

[0098] The connection member 135 (also referred to as a conductive member) is electrically connected to the memory 100 and the ground terminal 135a in the chip, and therefore the connection member 135 (also referred to as a conductive member) may be considered to be the chip 20. That is, the chip 20 includes the memory 100, the substrate 120, the communication terminal group 130, the conductive member 135, and the ground terminal 135a.

[0099] Contact pins 911-914 of contact pin assembly 91 are deformable, while the grounding member is non-deformable. When chip 20 comes into contact with contact pins 911-914, at least one of the contact pins is deformed. When conductive member 105 comes into contact with the grounding member, the grounding member does not deform, and even minute deformations invisible to the naked eye fall under the category of non-deformable. This structure is advantageous in ensuring stable transmission of electrical signals, particularly grounding signals, from chip 20.

[0100] It should be noted that a ground signal is usually output by the main CPU of a printing device, and the ground signal is output from the main CPU to the ground contact pin of the contact pin assembly, the ground member, etc. When an ink cartridge is installed in a printing device, it is necessary to ensure communication of the ground signal between the ink cartridge and the printing device. In the related art, the ground signal is transmitted between the ink cartridge and the printing device sequentially through the ground terminal of the terminal group of the chip and the ground contact pin.

[0101] However, in the present application, the ground signal is transmitted by a ground terminal, a conductive member, and a ground member. Optionally, in the present application, the ground signal is transmitted by a memory, a conductive member (also referred to as a connection member), and a ground member in a chip. Optionally, in the present application, the ground signal is transmitted by a memory, a ground terminal, a conductive member (also referred to as a connection member), and a ground member in a chip, thereby improving the stability of the transmission of the ground signal.

[0102] In this embodiment, the layout of the communication terminal group and the ground terminals provided on the chip on the chip substrate will be described in detail.

[0103] 7, in this embodiment, chip 20 includes substrate 120, which includes first surface 120a and second surface 120b arranged opposite each other, with first surface 120a being the front surface of substrate 120 and second surface 120b being the rear surface of substrate 120. First surface 120a is configured as the surface of the substrate that is close to printer contact pin assembly 91, and a communication terminal group is provided on first surface 120a, which includes a plurality of communication terminals 131 to 134.

[0104] The chip further includes a ground terminal 135a. The ground terminal 135a is provided on the first surface 120a or the second surface 120b. The ground terminal 135a is electrically connected to the conductive member 135 and forms a ground point of the chip.

[0105] In one embodiment, the first surface 120a has orthogonal first and second directions, and the first direction is configured as the installation direction of the ink cartridge 10 in a printing device. Each of the communication terminals has a first contact portion that contacts a contact pin. The first contact portion has a first projection onto the first surface 120a, and a first area is formed by being surrounded by the first projections of the multiple first contact portions onto the first surface 120a. A ground point formed by the conductive member and the ground terminal has a second projection onto the first surface 120a.

[0106] In the second direction, at least a portion of the second projection is located outside the first region. In other words, in the second direction, a portion of the second projection is located within the first region, and at least a portion of the second projection is located outside the first region. For example, when a portion of the second projection is located outside the first region, in the second direction, the second projection is close to one side of the first region, and the distance between the second projection and the first region is shorter than the length of the first region. Optionally, in the second direction, there is an overlapping portion between the second projection and the first region.

[0107] The chip 20 may have the following variations: Each of the different variations of the chip may be mounted on the ink cartridge 10.

[0108] Chip Variation 1. As shown in Figures 8 to 10, the difference between this modified example and the chip of embodiment 1 is that the chip 20 of this modified example has a memory 100, a substrate 120, and a group of terminals (corresponding to the communication terminal group of embodiment 1).

[0109] Memory 100 and a terminal group (corresponding to the communication terminal group in the first embodiment) are provided on chip substrate 120, and memory 100 is used to store information such as manufacturer information, ink amount information, consumable cartridge type information, ink color, etc. When consumable cartridge 10 is installed in printer installation portion 90, data transmission, confirmation, data interaction, etc. occur between memory 100 and the printer, and the connection between the two is realized by connecting the terminal group to contact pins of the printer. Furthermore, the shape of each terminal in the terminal group may be other shapes, such as a rectangle, square, circle, trapezoid, or other irregular shape.

[0110] In this modification, a terminal group is provided on the front surface 120a, and the terminal group includes a plurality of terminals (131-139). Of course, the memory 100 may be provided on any one or several of the surfaces from the front surface 120a to the bottom surface 120f. The top surface 120e and the bottom surface 120f are provided so as to face each other in the Z-axis direction. The specific shape and structure of the chip 20 are not limited, and can be determined by those skilled in the art according to specific design needs. The chip 20 may have, for example, a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shape structure, a trapezoidal structure, or a parallelogram structure.

[0111] There is no limitation on the location of memory 100. For example, memory 100 may be provided on the side closer to the rear end of chip 20 in the mounting direction, or on the side closer to the front end of chip 20 in the mounting direction, or memory 100 may be provided in the center of chip 20. Those skilled in the art will be able to provide memory 100 according to specific design needs, and therefore, a description thereof will be omitted here.

[0112] In this embodiment, the terminal group includes nine terminals, each with the following function and operation: The first terminal 131 and the second terminal 132 (reset terminals) are used to reset data inside the wafer; The third terminal 133 (clock terminal) is used to receive a clock signal; The fourth terminal 134, the fifth terminal 135, and the sixth terminal 136 (power terminals) are used to receive a power supply potential (e.g., 3.6 V) different from the ground potential and provide power for the operation of the memory 100; The seventh terminals 137a, 137b, 137c, and 137d (ground terminals) are used to indirectly receive the ground potential; The eighth terminal 138 (data terminal) is used to transmit or receive a data signal; and the memory 100 further includes a ninth terminal 139.

[0113] In this embodiment, the third terminal group includes a first terminal 131 and a fourth terminal 134, and the second terminal group includes a fifth terminal 135 and a ninth terminal 139. The third terminal group and the second terminal group are each an attachment detection terminal, and the first terminal 131 and the fourth terminal 134 may be short circuit detection terminals, with the other terminals being included in the first terminal group. When the consumable material cartridge 10 is attached to the printer, an electrical signal is transmitted between the attachment detection terminal and the printer to detect whether the consumable material cartridge 10 is attached. The fifth terminal 135 and the ninth terminal 139 are also referred to as high-voltage terminals, and are used to receive an attachment detection voltage (e.g., 42 V) and perform an attachment detection function related to the attachment of the consumable material cartridge to the attachment portion.

[0114] For example, a high resistor (e.g., 62 kΩ) is provided between the fifth terminal 135 and the ninth terminal 139, and by detecting a change in current or voltage, it is determined whether or not the consumable cartridge 10 is attached to the attachment portion. The first terminal 131 and the fourth terminal 134 are also called short circuit detection terminals, and by detecting a change in voltage on the terminals, it is possible to detect whether or not a short circuit has occurred on the chip 20, and also to determine whether or not the consumable cartridge 10 is attached to the printer based on whether or not the two are connected.

[0115] The first terminal 131 and the fourth terminal 134 are further used to detect whether a short circuit has occurred between the terminals, specifically, whether a short circuit has occurred between the fifth terminal 135 / ninth terminal 139 and the first terminal 131 / fourth terminal 134. If a short circuit occurs between the fifth terminal 135 / ninth terminal 139 and the first terminal 131 / fourth terminal 134, the printer detects that the voltage on the first terminal 131 / fourth terminal 134 has increased, and then presents information about the short circuit, thereby avoiding the risk of the chip or the printer being damaged by a short circuit.

[0116] Each terminal in the group of terminals has its own contact portion, which is indicated by a circle in FIG. 8 . The contact portion is the area of ​​the terminal that is most likely to come into contact with a contact pin when the consumable cartridge 10 is installed in a printer. When viewed along a direction perpendicular to the installation direction P, the arrangement order is the ground terminal (seventh terminal 137a, 137b, 137c, 137d), one second contact portion, one third contact portion, the first contact portion, another third contact portion, and another second contact portion, or (as shown in FIG. 8 ) the ground terminal and fifth terminal 135 are aligned in the Z direction. Of course, the ground terminals may be provided on the front surface 120a or the rear surface 120b of the chip. For example, the ground terminals may be provided at four positions, 137a, 137b, 137c, and 137d, as shown in FIGS. 8 and 9 . In this embodiment, the ground terminals 137a, 137b, 137c, and 137d are preferably provided on the front surface 120a or the rear surface 120b, and are arranged on the +Z side of the fifth terminal 135 or on the side biased from the +Z direction to the -Y direction.

[0117] Optionally, along the Z direction, the ground terminal (seventh terminal) is aligned with the first terminal 131. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131 and the fifth terminal 135. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fifth terminal 135. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134 and the ninth terminal 139. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the ninth terminal 139. The ground terminal (seventh terminal) is electrically connected to the memory 100 and the conductive member 140.

[0118] As shown in FIG. 11, in this embodiment, the memory 100 is provided on the rear surface 120b of the substrate 120, and a connecting member 140 (corresponding to the conductive member in the first embodiment and made of a conductive material with a certain hardness) is connected by soldering or contact to a conductive piece 140a (corresponding to the ground terminal in the first embodiment) on the rear surface 120b of the substrate 120 near the right surface 120d and the top surface 120e. The conductive piece 140a is a contact point provided in advance on the rear surface 120b of the substrate, and the contact point is connected to the memory 100 via a conductor provided inside the substrate 120. This achieves an electrical connection between the connecting member 140 and the memory 100.

[0119] Chip Variation 2. 12 and 13, a terminal group 130 on the substrate includes four communication terminals, each of which is a first terminal 131, a second terminal 132, a third terminal 133, and a fourth terminal 134. The first terminal 131 (data terminal) is used to transmit or receive a data signal, the second terminal 132 (clock terminal) is used to receive a clock signal, the third terminal 133 (power terminal) is used to receive a power supply potential (e.g., 3.6V / 3.3V) different from the ground potential and to provide power for the operation of the memory via the terminal, and the fourth terminal 134 (reset terminal) is used to reset data inside the wafer or adjust the processing device to a responsive state.

[0120] Each contact portion C1 to C4 has a first projection onto a first surface. The first surface has a first direction and a second direction that are orthogonal to each other. The first direction is the mounting direction P of the ink cartridge into the printing device, and in this case, the first surface is parallel to the first direction (i.e., the mounting direction P). Alternatively, the first direction may be the extension direction of a projection line of the mounting direction P of the ink cartridge into the printing device onto the first surface, and the first surface may be inclined with respect to the first direction. In other words, the substrate may be provided on the ink cartridge body so as to be inclined.

[0121] For example, the illustrated Z-axis direction is a first direction, the X-axis direction is a second direction, and the second direction is perpendicular to the first direction, in which case the first surface may be the front surface 120a or the back surface 120b of the substrate.

[0122] A first projection of each of the contact portions onto the first surface surrounds a first region M. For example, the substrate has regions Q1 and Q2 provided along the center line of the substrate, the first region M is within region Q1, the first to fourth terminals are within region Q1, each of the formed contact portions is within first region M, and of course, the first region is also within region Q1.

[0123] Furthermore, a ground terminal is further provided on the rear surface of the substrate. The ground terminal is also referred to as a fifth terminal / additional terminal. Ground terminals 135a, 135b, 135c, and 135d (corresponding to the ground terminals in the first embodiment) are connected to the conductive member and the memory. A ground point is formed by the connection between the ground terminal and the conductive member. The ground terminals may be arranged at four positions, 135a, 135b, 135c, and 135d.

[0124] For example, the first to fourth terminals are located within region Q1. Furthermore, region Q2 may not be provided or may be provided as small as possible. In this way, the chip dimensions can be reduced, and the chip, ink cartridge, and printer can be made smaller. When region Q2 is not provided or is provided as small as possible, region Q1 refers to the chip region where first terminal 131 to fourth terminal 134 are provided. The contact portions of first terminal 131 to fourth terminal 134 are located within first region M.

[0125] The positions of the ground terminals 135a, 135b, 135c, and 135d may be in region Q1 on the rear surface 120b, for example, at the positions indicated by the first additional terminal 135a or the second additional terminal 135b as shown in FIG. 13 , where the ground point formed has a second projection onto the first surface that is within region Q1 and that partially overlaps with the first region M. Alternatively, the fifth terminal 135 may be located in region Q1 on the front surface 120a, for example, at the position indicated by the fourth additional terminal 135d, where the ground point formed has a second projection onto the first surface that is within region Q1, that is, that the second projection is outside the first region M.

[0126] In some other embodiments, the position of fifth terminal 135 may be in second region Q2 on rear surface 120b, for example, the position indicated by third additional terminal 135c shown in Fig. 13. In this case, the formed ground point has a second projection onto the first surface outside first region Q1, i.e., the second projection is outside first region M. Furthermore, in some embodiments, the width of region Q2 in the X-axis direction may be smaller than the width of region Q1, and the distance between one side of the second projection closer to first region M and the first region may be smaller than the length of the first region.

[0127] Chip Variation 3. This third variation is similar to the first variation of the chip, with the following differences: As shown in FIGS. 14 and 64, in another example, eight terminals are provided on the front surface 120a of the substrate of this embodiment. Seventh terminals 137a and 137b are ground terminals on the rear surface 120b of the substrate 120. The seventh terminals may be provided at other positions on the rear surface 120b and are used to receive a ground potential. Furthermore, the number and shape of the seventh terminals are not limited as long as they are provided on the rear surface 120b. The chip 20 of this variation includes two seventh terminals that are approximately rectangular.

[0128] The ground terminal may be located in region Q1, for example, at the position where ground terminal 137a shown in Fig. 64 is provided. The ground terminal may be located in region Q2, for example, at the position where ground terminal 137b shown in Fig. 64 is provided.

[0129] Note that the contact pin assembly includes eight contact pins, each contacting a respective terminal on the front surface to form a respective contact (the contacts are indicated by circles in FIG. 14 ), which are the areas on the terminals that are most likely to come into contact with the contact pins when the ink cartridge 10 is installed in a printer.

[0130] 64, a first region M is formed by being surrounded by the first projections formed by each contact portion on the first surface, and a ground point is formed by connection between the ground terminal and the conductive member. The projection of the ground point onto the first surface is a second projection. When ground terminal 137a forms the ground point, at least a portion of the second projection is within first region M and at least a portion is outside first region M, i.e., the second projection and first region M at least partially overlap. When ground terminal 137b forms the ground point, at least a portion of the second projection is within first region M and at least a portion is outside first region M, i.e., the second projection and first region M at least partially overlap.

[0131] 7 and 15, the chip 20 has a positioning hole, and the ink cartridge body 50 is provided with a positioning post that fits into the positioning hole, and the positioning of the chip 20 is completed when the positioning post is inserted into the positioning hole of the chip 20. Furthermore, the chip 20 may be fixed to the ink cartridge body 50 by welding.

[0132] Specifically, the chip 20 of this embodiment has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are each a through-hole in the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120.

[0133] The first hole 121 is a rectangular recess formed from the top surface of the substrate to the bottom surface 120f, and the second hole 122 is a through-hole located on the surface 120a / 120b of the substrate 120, closer to the bottom surface 120f. Correspondingly, the ink cartridge corresponding to the chip is provided with a chip mounting portion. The chip mounting portion includes a first positioning post 601 that fits into the first hole 121 and a second positioning post 602 that fits into the second hole 122. The first positioning post 601 and the second positioning post 602 are inserted into the first hole 121 and the second hole 122, respectively, and joined together. The chip 20 is then fixed to the case 50 (also referred to as the ink cartridge body 50) by welding using a thermal welding head. This configuration prevents misalignment of the chip 20 during installation or use. Specifically, positioning can be achieved in three directions: the X-axis, Y-axis, and Z-axis.

[0134] It should be understood that the number of the positioning holes is not limited, and specifically, only one positioning hole (e.g., first hole 121) may be provided, or two or more positioning holes may be provided. The shape of the positioning hole is also not limited, and the positioning hole may be a round hole, a square hole, or an irregularly shaped hole. Similarly, the specific shapes and numbers of the positioning posts and limiting portions are not limited.

[0135] Based on the above embodiment, the ink cartridge body of the embodiment of the present application has a fixing assembly 603 provided on the -Y axis side of the handle 30, and the fixing assembly 603 has a first fixing member 603a, a second fixing member 603b and a third fixing member 603c, and the third fixing member 603c restricts the connecting member 135 (also called the conductive member) to the ink cartridge body 50, and the first fixing member 603a and the second fixing member 603b are arranged opposite to each other and clamp the connecting member 135, allowing the connecting member 135 to be bent at a right angle and bent in a direction away from the ink cartridge body 50.

[0136] This configuration makes it possible to fix the connecting member 135 (also called a conductive member) and prevent poor contact between the connecting member 135 and a grounding member (not shown) of the printer due to swinging of the connecting member 135. Furthermore, because the connecting member 135 is bent at a right angle, it is advantageous to adjust the connecting member 135 so that it extends toward the grounding member of the printer, facilitating electrical contact with the grounding member of the printer, preventing excessive current, and reducing the risk of electric shock due to unstable grounding.

[0137] As shown in Figure 16, during the process of mounting an ink cartridge 10 having a chip 20 of this embodiment into a mounting portion 90, electrical connection is established between each of the first terminals 131 to fourth terminals 134 and the second surface portions 911a2 to 914a2 of the corresponding first portions 911a to 914a of the first contact pin 9111 to fourth contact pin 914, respectively.

[0138] 1 and 2, when the ink cartridge 10 is installed in the installation portion, one end of the connecting member 135 is connected to a ground terminal provided on the rear surface 120b of the substrate, and the ground terminal is electrically connected to the memory 100, the connecting member 135 extends from the rear surface 120b of the substrate and extends in the +Z axis direction in close contact with the ink cartridge body 50, and the first fixing member 603a and the second fixing member 603b act on the portion of the connecting member 135 bent at a right angle to bend the connecting member 135 toward a metal member (also referred to as a ground member) of the printer. Note that in the embodiment of the present application, the metal member may be a part of the ground member or may be the ground member, and the metal member is provided in the installation chamber of the printer, the metal member (also referred to as the ground member) is grounded, and a ground signal is transmitted over the metal member.

[0139] Furthermore, the connecting member 135 is electrically connected to the printer's grounding member and is grounded via the grounding member. This configuration places the electrical connection between the grounding member and the conductive member above the chip, improving the stability of the chip's grounding, improving the safety of chip use, and reducing the occurrence of situations where the printing device is unable to identify the ink cartridge. The connecting member 135 (conductive member) is electrically connected to the conductive wall plate 81 at its end 135e (as shown in FIG. 15). Specifically, the end 135e (as shown in FIG. 15) of the connecting member 135 (conductive member) on the +X axis side is electrically connected to the conductive wall plate 81.

[0140] In the embodiment of the present application, the mounting portion 90 is movably mounted within the mounting chamber, the grounding member is provided outside the mounting portion, and a portion of the conductive member is provided within the mounting portion's receiving chamber and electrically connected to the ground terminal of the chip. A portion of the conductive member is provided outside the mounting portion and is used to electrically connect to the grounding member. That is, the ground terminal of the ink cartridge chip is electrically connected to the grounding member via the conductive member to realize the transmission of a ground signal.

[0141] Any type of chip can be applied to ink cartridges of different embodiments and examples.

[0142] Furthermore, since the mounting portion is slidably attached to the ground rail, in order to ensure smooth sliding of the mounting portion, in the embodiment of the present application, the contact point between the conductive member and the ground member may be configured as a ball or ball bearing. The ball or ball bearing is electrically connected to the conductive member as part of the conductive member. This configuration reduces the frictional force with the conductive member at the contact point, ensuring smooth sliding of the mounting portion and the ink cartridge on the ground rail.

[0143] The conductive member may be considered to be a part of the chip. When the conductive member is considered to be a part of the chip, the chip is detachably mounted on the printing device, and the printing device has a mounting chamber, a mounting portion and a grounding member provided in the mounting chamber, the mounting portion having a storage chamber and a contact pin assembly, and the grounding member is located at a position other than the position where the contact pin assembly is provided. The chip has a communication terminal group, a conductive member (also referred to as a connection member), and a memory. The communication terminal group is electrically connected to the contact pin assembly. The conductive member is electrically connected to the grounding member and the memory. The chip can also achieve the beneficial effects of the present application.

[0144] It should be noted that the grounding member and the contact pin assembly are two different members. Furthermore, the tip is provided on the ink cartridge body, and at least a portion of the ink cartridge body and the tip may be located within the receiving chamber, and the conductive member is provided within the mounting chamber.

[0145] Example 2 of Embodiment 1 The embodiment of the present invention differs from the above-described examples in the following respects. 17 to 20, the grounding member according to the embodiment of the present application includes a ground rail 80, which is grounded. The ground rail 80 is provided in an attachment chamber, and the mounting portion 90 is slidably provided on the ground rail 80. In other words, the ground rail 80 functions not only as a mounting member for the mounting portion 90, but also as a grounding member that transmits a ground signal.

[0146] In one embodiment, the ground rail 80 has a conductive wall plate 81 on the side facing the mounting portion, and the conductive wall plate 81 is connected to the grounding member. The two may be integral, and the embodiment of the present application is not limited thereto. The lengthwise extension direction of the conductive wall plate 81 coincides with the extension direction of the ground rail 80, and the conductive wall plate 81 intersects with the horizontal plane. For example, the conductive wall plate 81 may be perpendicular to the horizontal plane or inclined relative to the horizontal plane.

[0147] Specifically, in this embodiment, the ink cartridge 10 further includes a connecting member 135 (corresponding to a conductive member). The connecting member 135 is used to connect the chip 20 to another metal part of the printing device (corresponding to a grounding member) and functions to ground the chip 20. In other words, the connecting member 135 is configured as a conductive member. For example, the connecting member 135 includes a connecting main body 135bb and a conductor 135cc. The connecting main body 135bb and the conductor 135cc may be integrally formed or may be separately formed, but this is not limited to the embodiment of the present application. The connecting member 135 may be a metal member such as copper, aluminum, or steel, or may be a member made of conductive silicone, conductive plastic, or the like.

[0148] The connecting member 135 has one end closest to the chip electrically connected to a conductive piece 135a (corresponding to a ground terminal), which is provided on the substrate 120 and electrically connected to the memory of the chip 20. The memory must be grounded, and the connection between the conductive piece 135a and the memory is not limited. For example, the conductive piece 135a can be connected to the memory via a conductor, thereby connecting the connecting member 135 and the memory. The position of the conductive piece 135a on the substrate 120 is not limited. In this embodiment, the conductive piece 135a is provided on the rear surface 120b of the chip, on a different surface from the surface on which other terminals are provided on the chip 20. This prevents short circuits between the conductive piece 135a and other terminals, improves the stability of the chip grounding, and improves the safety of chip use. The conductive piece 135a (corresponding to a ground terminal) is a copper coating formed on the chip 20 by a process such as electroplating.

[0149] The conductor 135cc is provided in the ink cartridge body 50 and contacts other metal parts of the printer (corresponding to the grounding member). Preferably, the conductor 135cc is provided inside the ink cartridge body 50. This prevents the conductor 135cc from being damaged by contact with external objects and ensures that the grounding function of the connection member 135 is stably realized. In this embodiment, the conductor 135cc is provided inside the handle 30. The connection main body 135bb is used to connect the conductive piece 135a and the conductor 135cc.

[0150] Specifically, the connecting body 135bb has a first portion 135b1, a second portion 135b2, and a connecting portion 135b3. The first portion 135b1 is used for connection with the conductive piece 135a. The material of the first portion 135b1 and the form of connection with the conductive piece 135a are not limited. For example, the first portion 135b1 may be made of a conductive material having a certain hardness and may be connected to the conductive piece 135a by soldering.

[0151] In other embodiments, the connecting member 135 (corresponding to the conductive member) may not be provided with the conductive piece 135a. That is, the first portion 135b1 is directly connected to a memory (not shown) of the chip 20. The connection form between the first portion 135b1 and the memory is not limited, and for example, the first portion 135b1 may be directly connected by solder to a conductive wire connected to the memory. connection Part 135b 3 is used to connect with conductor 135cc. Second Part 135b 2 The first portion 135b1 and connection Part 135b 3 Preferably, second portion 135b2 and / or The connecting portion 135b3 is provided in a corresponding groove in the ink cartridge body 50. Second Part 135b 2 This prevents the connecting member 135 from being damaged by external objects and affecting its conductive function, while also fulfilling its fixing function.

[0152] 21 and 22, in this embodiment, conductor 135 cc is provided inside handle 30. Handle 30 includes main body portion 301, extending portion 302, limiting portion 303, engaging portion 304, and connecting portion 305. Extending portion 302, limiting portion 303, engaging portion 304, and connecting portion 305 are each provided on main body portion 301, and their arrangement on main body portion 301 is not limited, and may be, for example, detachably connected or fixedly connected.

[0153] One end of the extension 302 in the X-axis direction is connected to the main body 301, and the other end is in contact with another metal part of the printer (corresponding to the grounding member). In this embodiment, the other end of the extension 302 is in contact with the conductive wall plate 81 of the printer, thereby bringing the conductor 135cc into contact with the conductive wall plate 81 and establishing an electrical connection. The extension 302 functions to protect the conductor 135cc from damage, breakage, displacement, etc. due to a collision.

[0154] The contact area between the conductive wall plate 81 and the connecting member 135 in this embodiment is larger than the contact area between the contact pin and the ground terminal of the chip in a conventional ink cartridge mounting part. This ensures a stable electrical connection between the connecting member 135 and the ground rail 80, ensures proper contact, stably realizes the grounding function of the chip 20, prevents excessive current, and reduces the risk of electric shock due to unstable grounding.

[0155] Based on the above embodiment, the extension portion 302 of the present embodiment is further provided with a color identifying portion 302a for indicating the color of ink stored in the ink cartridge. The form of indicating the ink color by the color identifying portion 302a is not limited, and the color of ink stored in the ink cartridge can be indicated by, for example, color, pattern, character, or a combination thereof.

[0156] The limiting portion 303 engages with a limiting protrusion 502 provided on the ink cartridge to limit the range of movement of the handle 30 in the X-axis direction. The position and shape of the limiting protrusion 502 on the ink cartridge body 50 are not limited, and for example, the limiting protrusion 502 may be a cylinder, a cone, or a protrusion with an irregular shape. In this embodiment, the limiting protrusion 502 is a cylinder.

[0157] The engaging portion 304 is used to engage with the fixing portion 90d provided on the mounting portion 90 to fix the ink cartridge 10 to the mounting portion 90 and prevent the ink cartridge 10 from being removed from the mounting portion 90. The connecting portion 305 is used to connect the handle 30 to the ink cartridge body 50 of the ink cartridge. The connection form between the connecting portion 305 and the ink cartridge body 50 is not limited and may be, for example, a detachable connection or a fixed connection. In other embodiments, the handle 30 may not be provided with the connecting portion 305, and the main body portion 301 may be directly connected to the ink cartridge body 50.

[0158] When the ink cartridge 10 is installed in the installation part, one end of the connection member 135 is a conductive piece 135a, which connects to the memory in the ink cartridge chip 20 and receives the current output from the chip 20. The conductive piece 135a transmits the received current to the conductor 135cc via the connection body 135bb. The other end of the connection member 135 is a conductor 135cc, which connects to another metal part in the printer and transmits the current received from the connection body 135bb to the other metal part of the printer, thereby fulfilling the function of grounding the chip.

[0159] Specifically, the conductor 135cc penetrates the handle 30. The conductor 135cc penetrates the main body portion 301, the extension portion 302, and the connection portion 305 of the handle 30. The engagement portion 304 on the main body portion 301 of the handle engages with the fixing portion 90d on the mounting portion 90, and is used to secure the ink cartridge 10 to the mounting portion 90. The conductor 135cc penetrates the handle 30 and is relatively close to the engagement portion 304 on the handle 30. This ensures stable and accurate contact between the connecting member 135 and other metal parts of the printer, ensures stable realization of the grounding function of the chip 20, prevents excessive current, and reduces the risk of electric shock due to unstable grounding. Ensuring good grounding stability of the chip improves the safety of chip use and reduces the occurrence of situations in which the printing device is unable to identify the ink cartridge.

[0160] Example 3 of Embodiment 1 23 to 26 are schematic diagrams relating to Example 3 of Embodiment 1 of the present application. The differences between this example and Example 2 are as follows. As shown in FIGS. 23 to 26, FIG. 23 is a schematic diagram of the ink cartridge 10 being mounted in the mounting portion 90, where the grounding member has a grounding rail, the grounding rail has a conductive wall plate 81, and the conductive member 105 contacts the conductive wall plate 81 and transmits a ground signal. A stopper 84 is provided in the +Z-axis direction of the conductive wall plate 81.

[0161] Generally, the stopper 84 is made of plastic and non-conductive material. In the X-axis direction, the end of the stopper 84 is closer to the mounting portion 90 than the end of the conductive wall plate 81 (i.e., the stopper 84 is closer to the mounting portion 90 than the end of the conductive wall plate 81). of 4 (The end of the conductive member 105 is closer to the +Z axis and -X axis sides than the conductive wall plate 81.) Therefore, when the ink cartridge 10 is being installed in the printing device, the conductive member 105 4 It must cross over and then contact the conductive wall plate 81.

[0162] In this embodiment, one end of the conductive member 105 contacts the ground terminal 135a of the chip 20, and the other end contacts the conductive wall plate 81 of the ground member. The transmission path of the ground signal passes through the memory of the chip 20, the ground terminal 135a, the conductive member 105, and the conductive wall plate 81 of the ground member in this order.

[0163] The handle 30 has a main body portion 301, an extending portion 302, an engaging portion 304, a first gap 308, and a second gap 309. The ink cartridge further has a fixing portion 307 for fixing the conductive member 105. The extending portion 302 has a horizontal extending portion 3025, a first curved portion 3021, a second curved portion 3022, a contact accommodating portion 3023, and a fixing hole 3024. The extending portion 302 is provided for the purposes of fixing the conductive member 105, allowing the conductive member 105 to pass over the stopper 84, and abutting the conductive member 105 against the conductive wall plate 81. The horizontal extending portion 3025 extends in the +X-axis direction and is intended to more reliably abut the conductive member 105 against the conductive wall plate 81.

[0164] The first curved portion 3021 extends from the horizontally extending portion 3025, and the first curved portion 3021 extends in the +X-axis direction (toward the conductive wall plate 81) and the +Z-axis direction (upward), while the second curved portion 3022 extends from the first curved portion 3021, and the second curved portion 3022 extends in the -X-axis direction (away from the conductive wall plate 81 / toward the case) and the +Z-axis direction (upward). This structural design guides the extending portion 302 and the conductive member 105 to pass over the stopper 84 when the ink cartridge 10 is installed in the printing device, and also guides the deformation / compression of the handle 30 by the second curved portion 3022 when the ink cartridge 10 is removed from the printing device, making it easier to remove the ink cartridge 10.

[0165] The contact accommodating portion 3023 is used to accommodate the contact portion 1057 of the conductive member 105, and the contact portion 1057 is used to contact the conductive member 105 with the conductive wall plate 81. The contact accommodating portion 3023 is relatively a recessed portion, which can protect the contact portion 1057 to some extent and reduce damage. The contact accommodating portion 3023 is provided at the intersection of the first curved portion 3021 and the second curved portion 3022, and positions the contact portion 1057 closest to the +X axis of the ink cartridge 10, allowing the conductive member 105 and the conductive wall plate 81 to easily contact each other.

[0166] Furthermore, by engaging the fixing hole 3024 with the elastic portion 1056, the conductive member 105 is stably fixed to the ink cartridge 10, preventing the conductive member 105 from coming off the ink cartridge 10. The handle 30 extends from the ink cartridge body 50 and has a certain degree of elasticity, allowing it to contract toward the −X-axis direction and return to its original position. Because the extension portion 302 is located on the handle 30, the extension portion 302 also has a certain degree of elasticity, allowing it to move toward the −X-axis direction, allowing the conductive member 105 to pass over the stopper 84. When the handle 30 is compressed, it tends to move toward the +X-axis, applying pressure to the abutting portion 1057, allowing the abutting portion 1057 to more securely abut against the conductive wall plate 81. The abutting portion 1057 is located at the intersection of the first curved portion 3021 and the second curved portion 3022.

[0167] The conductive member 105 includes a first portion 1051a, a second portion 1051b, and a third portion 1051c. The first portion 1051a is fixed to the ink cartridge body 50, and more specifically, the engagement between the through hole 1053 and the fixing portion 307 prevents the conductive member 105 from coming off the ink cartridge body 50. The through hole 1053 and the fixing portion 307 are tightly fitted together.

[0168] Optionally, after the through-hole 1053 and the fixing portion 307 are fitted together, the portion of the through-hole 1053 that protrudes from the fixing portion 307 may be secured to the first portion 1051a by welding or hot melt. This prevents the conductive member 105 from detaching from the ink cartridge body 50. The second portion 1051b fits into the main body portion 301 of the handle 30, and has a first gap 308 on the -X axis direction side of the engagement portion 304 and the +X axis direction side of the main body portion 301. The first gap 308 accommodates a portion of the second portion 1051b. The third portion 1051c is shaped to fit the extension portion 302, allowing the conductive member 105 to abut against the conductive wall plate 81 more reliably.

[0169] The third portion 1051c is provided with an abutting portion 1057 and an elastic portion 1056. The abutting portion 1057 is provided in the abutting accommodation portion 3023. The elastic portion 1056 is a sheet-like elastic member extending from the conductive member 105 and fits into the fixing hole 3024 to fix the conductive member 105 to the handle 30. The conductive member 105 has a first curved region AA extending toward the conductive wall plate 41 and a second curved region BB connected to the first curved region AA and extending upward (in the +Z-axis direction). The contact position between the conductive member 105 and the conductive wall plate 81 is located in the second curved region BB; that is, the abutting portion 1057 is located in the second curved region BB.

[0170] The first curved region AA is aligned with the first curved portion 3021 of the extending portion 302, and extends in the +X-axis direction (the direction of the conductive wall plate 81) and the +Z-axis direction (upward). The second curved region BB is housed in the contact housing 3023 and is connected to the first curved region AA, extending upward (in the +Z-axis direction). This structure is advantageous for contact between the conductive member 105 and the conductive wall plate 81. The contact portion 1057 is a protrusion in the second curved region BB. The contact portion 1057 may be an arc-shaped, spherical, linear, or dot-shaped protrusion, and is preferably a spherical protrusion (as shown in FIG. 26 ). This allows for easy contact with the conductive wall plate 81, reducing friction between the contact portion 1057 and the conductive wall plate 81 when the ink cartridge 10 slides in the mounting portion 90, ensuring smooth sliding of the ink cartridge 10.

[0171] Because the handle 30 is elastic, it can contract and return to its original state. The handle 30 has two states: an initial state and a contact state. The conductive member 105 can be switched between the initial state and the contact state. In the initial state, the conductive member 105 is farther from the ink cartridge body 50 than in the contact state. In the initial state, the conductive member 105 is farther from the ink cartridge body 50 than in the contact state. When the ink cartridge 10 is installed in the printing device, the contact portion 1057 of the conductive member 105 applies pressure to the conductive wall plate 81, allowing the contact portion 1057 and the conductive wall plate 81 to contact each other more securely.

[0172] The conductive member 105 may be made of a conductive material such as metal, conductive silicone, or conductive plastic. Optionally, the conductive member 105 is made of metal and folded to form the structure shown in FIGS. 23 to 25. The abutting portion 1057 may be made by heat pressing (a spherical protrusion is formed on the surface of an originally flat metal plate by heat pressing). The elastic portion 1056 may be made by stamping (a suspended elastic portion 1056 is formed by punching one end of the elastic portion 1056). The through-hole 1053 may be made by stamping (a through-hole is formed by punching).

[0173] Example 4 of Embodiment 1 27 is a schematic diagram of Example 4. In this example, the description of the ink cartridge is the same as in Embodiment 1, and the chip is either Chip Modification 1 or Chip Modification 3, and the description thereof will be omitted here.

[0174] Embodiment 2 In this embodiment, the manner in which the ink cartridge is inserted into the mounting portion is different from that in embodiment 1, and the structure of the mounting portion of the printer is also different. In embodiment 2, the mounting portion 90 is fixed within the mounting chamber, and the grounding member is provided within the storage chamber.

[0175] The ink cartridge of embodiment 2 can be adapted to some ink cartridges of embodiment 1. The difference between embodiment 2 and embodiment 1 is that embodiment 2 provides an antenna-type conductive member, and at least a portion of the wall forming the mounting chamber is configured as a grounding member, one end of the conductive member is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least a portion of the upper wall of the mounting chamber, with the electrical connection point between the two being located above the chip.

[0176] Based on the above embodiment, the conductive piece 135a of the conductive member in this embodiment may be omitted, the connecting member 135 may be directly connected to the conductor by soldering, and the position of the positioning hole provided in the chip is also different from that in the above embodiment 1.

[0177] 28 to 31, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are through-holes in the substrate 120, penetrating the front surface 120a and the rear surface 120b of the substrate 120. Here, the first hole 121 is a semicircular recess formed by recessing from the left surface 120c to the right surface 120d, and the second hole 122 is a semicircular recess formed by recessing from the right surface 120d to the left surface 120c.

[0178] Accordingly, the ink cartridge is provided with a chip mounting portion. The chip mounting portion includes a first positioning post 601 and a second positioning post 602. The first positioning post 601 and the second positioning post 602 protrude and engage with the first hole 121 and the second hole 122, respectively. The chip 20 is then fixed to the ink cartridge body 50 by welding using a thermal welding head. This configuration prevents the chip 20 from shifting position during the mounting process or during use after mounting is complete.

[0179] 30 and 31, when the consumable goods cartridge 10 is mounted in the mounting portion 90, one end of the connecting member 135 is connected to the ground terminal 135a of the memory 100 / rear surface 120b provided on the rear surface 120b of the substrate, the connecting member 135 extends from the rear surface 120b of the substrate and comes into close contact with the case 50 (ink cartridge body 50) in a direction away from the chip 20 of the case 50, and near the end of the connecting member 135, the connecting member 135 is bent in a direction away from the surface of the case 50 and is connected to a metal member 96 (corresponding to the grounding member in the first embodiment) in the printing device. A beneficial effect of such a design is that the stability of the chip grounding is good, improving the safety of using the chip.

[0180] When the ink cartridge 10 is mounted in the mounting portion 90, the connecting member 135 connected to the memory 100 comes into close contact with (or may abut) the rear surface 120b of the chip 20, extends to the top surface of the ink cartridge 10, and then extends along the top surface of the ink cartridge 10 from the top end of the chip 20 and the top surface of the ink cartridge 10, enters the gap in the mounting portion, and the end of the connecting member 135 is bent at a right angle. End 135e of the connecting member 135 (the end away from the ink cartridge body) abuts against the metal member 96 (corresponding to the grounding member in the first embodiment).

[0181] The connecting member 135 (the conductive member in the first embodiment) is bent away from the surface of the ink cartridge body 50 and faces the metal member 96 of the printer (the space that houses the ink cartridge 10). The metal member 96 is the first side wall 90c of the mounting portion in the present embodiment; that is, at least a portion of the wall that forms the housing chamber is configured as a grounding member, and the electrical connection between the grounding member and the conductive member is located above the tip. This configuration improves the stability of the tip grounding and improves the safety of using the tip.

[0182] The connecting member 135 has one end connected to the rear surface 120b of the substrate 120 and the other end connected to the metal member 96 of the printing device. The metal member 96 of the printing device is not limited to, and may be any metal in the printing device that is contacted by the connecting member 135.

[0183] Embodiment 3 In this embodiment, the method of inserting the ink cartridge into the mounting portion is different from that in the first embodiment, and the structure of the mounting portion of the printer is also different. 3 The mounting portion 90 is fixed in the mounting chamber, and the grounding member is provided in the receiving chamber.

[0184] In this embodiment, another antenna-type conductive member is provided, and at least a portion of the wall forming the mounting chamber is configured as a grounding member, and one end of the conductive member is electrically connected to the ground terminal of the chip and the other end is electrically connected to at least a portion of the wall of the mounting chamber.

[0185] Example 1 of Embodiment 3 As shown in FIG. 32, the first terminal 131 to the fourth terminal 134 are provided on the front surface 120a of the chip 20, and the positions and arrangement of their respective contact portions C, the memory 100, the connecting member 135, and the second hole 122 of the positioning hole of the substrate are the same as those in the second embodiment, and therefore, description thereof will be omitted here.

[0186] The connection member 135 (corresponding to the conductive member in the first embodiment) that connects to the memory 100 is in close contact with (or may abut) the rear surface 120b of the chip 20, extends to the top surface of the ink cartridge 10, and then extends along the top surface of the ink cartridge 10 from the top end of the chip 20 and the top surface of the ink cartridge 10, entering the gap in the mounting portion. The end 135e of the connection member 135 (the end that is away from the ink cartridge body) abuts the grounding member. The extending portion of the connection band 135 (also referred to as the connection member 135) (corresponding to the conductive member in the first embodiment) is bent in a direction away from the surface of the case 50 and faces a metal member (corresponding to the grounding member in the first embodiment) of the printing device (the space that houses the ink cartridge 10). This establishes an electrical connection with the metal member of the printing device.

[0187] Example 2 of Embodiment 3 In Example 2, another antenna-type conductive member is provided, in which at least a portion of the wall forming the mounting chamber is configured as a grounding member, and one end of the conductive member is electrically connected to the ground terminal of the chip and the other end is electrically connected to at least a portion of the wall of the mounting chamber.

[0188] In this embodiment, the manner in which the ink cartridge is inserted into the mounting portion is different from that in the first embodiment, and the structure of the mounting portion of the printer is also different, so the directions expressed by the three-dimensional coordinate system in this embodiment are also different from those in the first embodiment. 3 In the example, the mounting portion 90 is fixed in the mounting chamber, and the grounding member is provided in the accommodation chamber.

[0189] 33, the printer in this embodiment includes a printing unit 4 and a base 5. The base 5 includes a bracket and one or more mounting portions 90.

[0190] Furthermore, one mounting portion 90 can accommodate one ink cartridge 10. If the number of mounting portions 90 is four (as shown in FIG. 33), the four ink cartridges 10 can store ink of four different colors (e.g., black, yellow, cyan, and magenta). Also, if six ink cartridges 10 can be installed in the base 5, the number of mounting portions 90 is six, and the six ink cartridges 10 store ink of black, yellow, cyan, magenta, light cyan, and light magenta, respectively. Furthermore, multiple mounting portions 90 may store ink of the same color (e.g., black) inside.

[0191] First, insert the ink cartridge 10. ,direction The ink cartridge 10 is mounted on the tray 97 along the direction D1, and the assembly of the ink cartridge 10 and the tray 97 Gakata The base 5 is mounted in the mounting portion 90 along the direction D2. When the printer is printing, the base 5 provides ink to the printing operation of the printing unit 4 to ensure the normal execution of the printing operation of the printing unit 4. When the printer is placed in its natural state, the printing unit 4 is located directly above the base 5.

[0192] 33 shows a three-dimensional orthogonal XYZ coordinate system, with the X, Y, and Z axes being orthogonal to one another. When the printer is placed in its natural state, the gravity direction is the +Z direction, and the mounting direction D2 of the ink cartridge 10 into the mounting portion 90 is the +Z direction. (direction The direction D2) is the +Y direction, and the arrangement direction of the mounting portion 90 is the +X direction. .direction The direction D1 is the +Z direction. When the ink cartridge 10 is mounted in the mounting portion 90, first, How to The ink cartridge 10 is mounted on the tray 97 along the direction D1, and the assembly of the ink cartridge 10 and the tray 97 is mounted on the mounting portion 90 along the mounting direction D2.

[0193] As shown in Figure 34, this structure is the portion of the base 5 in the +Y direction, and when the ink cartridge 10 (which may be an assembly) is attached to the attachment portion 90 along the attachment direction D2, the front end side of the ink cartridge 10 in the +Y direction comes into contact with the structure shown in Figure 34, ensuring proper attachment between the ink cartridge 10 (which may be an assembly) and the attachment portion 90.

[0194] The internal structure of the mounting portion 90 includes a fixed frame. The fixed frame includes a contact pin assembly 91, an ink supply portion 92 (ink injection tube), a columnar positioning portion, and a 9 3f, 9 3s and a locking portion 94 are provided. The locking portion 94 is a rod-shaped member that can be swung and reset, that is, the locking portion 94 is configured as the conductive swinging rod of the present application. The rod-shaped member has a protrusion that extends in the -Z axis direction at its movable end. The protrusion is configured to engage with a groove in the bottom of the tray 97 to fix the assembly of the ink cartridge 10 and the tray 97.

[0195] The contact pin assembly 91 can be electrically connected to the chip of the ink cartridge 10 when the assembly is mounted in the mounting portion 90. The contact pin assembly 91 includes a plurality of contact pins (not shown) made of an elastic conductive steel sheet. The contact pin assembly 91 is inclined within the mounting portion 90, and a detailed structure of the contact pin assembly 91 will not be described here and can be seen in FIG. 4. Specifically, the assembly is mounted or removed along the +Y and -Y directions shown in the figure, and the assembly is physically engaged with the mounting portion 90 by a case and electrically connected to the contact pin assembly 91 via the chip of the ink cartridge.

[0196] 35 to 38, the ink cartridge 10 includes a chip 20, a connecting member 60, a print head 40, and an ink bag 10a. The chip 20 is provided on the front end side of the ink cartridge 10 in the mounting direction D2. The connecting member 60 is configured as a conductive member, and is made of a conductive material, with one portion connected to the chip 20 and another portion connected to a ground member.

[0197] An ink outlet 41 is provided on the +Y axis side of the print head 40. Ink is stored in the ink bag 10a, and the ink outlet 41 communicates with the liquid inside the ink bag 10a, and the ink reaches the ink inlet tube 92 through the ink outlet 41. The ink inlet tube 92 can supply ink to the print head, so that the print head can be used to perform a printing operation.

[0198] According to the above invention, the ground signal is transmitted to the chip 20 by a metal member or a conductive member, improving stability and reducing situations where grounding is not possible or where grounding becomes unstable. No ground terminal is provided on the substrate, and the connecting member improves the stability of the chip's grounding, prevents excessive current, and reduces the risk of electric shock due to unstable contact between the ground terminal on the chip and the contact pin on the printer, which is advantageous to improving the safety of chip use and reducing the occurrence of situations where the printing device is unable to identify the ink cartridge.

[0199] In the above embodiment, the metal member of the mounting unit 90 (corresponding to the grounding member in the first embodiment) may be the outer casing of the mounting unit 90 (the outer casing in the +Z-axis, -Z-axis, +X-axis, -X-axis, and +Y-axis directions) or a part of the outer casing. For user safety, all of the metal members of the mounting unit 90 are grounded, and a ground signal is shared between the mounting unit 90 and the printer. Preferably, in this embodiment, another part of the connection member 60 (corresponding to the conductive member in the first embodiment) is connected to a part of the metal member 96 in the -Z-axis direction of the mounting unit 90. In other words, at least a part of the wall of the storage chamber forms the grounding member. As shown in FIG. 33 , the metal member 96 is provided in the -Z-axis direction of the base 5, and a ground signal is shared between the metal member 96 (corresponding to the grounding member in the first embodiment) and the printer 1.

[0200] 35 and 36, chip 20 according to this embodiment includes memory 100, substrate 120, and a plurality of terminals 130. Substrate 120 includes front surface 120a, rear surface 120b, left surface 120c, right surface 120d, top surface 120e, and bottom surface 120f. Here, front surface 120a and rear surface 120b are arranged to face each other, left surface 120c and right surface 120d are arranged to face each other, and top surface 120e and bottom surface 120f are arranged to face each other.

[0201] Furthermore, the chip 20 includes a first hole 121, a second hole 122, a third hole 123, and a fourth hole 124. The first hole 121, the second hole 122, the third hole 123, and the fourth hole 124 are through-holes in the substrate 120, and penetrate the front surface 120a and the rear surface 120b of the substrate 120, respectively.

[0202] Here, the first hole 121 is a recess formed by recessing from the top surface 120e to the bottom surface 120f, the second hole 122 is a recess formed by recessing from the bottom surface 120f to the top surface 120e, the third hole 123 is a recess formed by recessing from the left surface 120c to the right surface 120d, and the fourth hole 124 is a recess formed by recessing from the right surface 120d to the left surface 120c.

[0203] With this configuration, ink cartridge 10 capable of mounting chip 20 of this embodiment is provided with a chip mounting section that includes a plurality of positioning posts that protrude from each other and are coupled to first hole 121, second hole 122, third hole 123, and fourth hole 124, and chip 20 is fixed to print head 40 by welding with a thermal welding head. This prevents chip 20 from shifting in position along the Y-axis or Z-axis during the mounting process or during use after mounting is complete.

[0204] As in the first embodiment, the terminals 131 to 134 provided on the front surface in this embodiment are communication terminals, and the uses of the communication terminals and their arrangement on the front surface are the same as in the first embodiment, so a description thereof will be omitted here.

[0205] The connection member 60 (corresponding to the conductive member in the first embodiment) and the memory 100 may be connected via a fifth terminal / additional terminal 135a (corresponding to the ground terminal in the first embodiment) and its wiring. Of course, in this embodiment, the fifth terminal 135a may not be provided, and the connection member 60 may be directly connected to the memory 100. Preferably, the fifth terminal 135a is used to more effectively connect the connection member 60 and the memory 100 and to make the contact more stable.

[0206] Furthermore, the conductive member and the fifth terminal / additional terminal 135a may be connected by soldering or fixing. Each terminal 130 has one contact portion, which are the first to fourth contact portions. The contact portions are areas of the terminals 130 that are most likely to come into contact with the contact pins when the ink cartridge is installed in the printer.

[0207] In the embodiment of the present application, the connection member 60 is a conductive member, and is made of a conductive material, and the printer's ground signal is connected to the memory via the conductive member and the fifth terminal / additional terminal (corresponding to the ground terminal). As a result, both the ink cartridge chip and the ground member are grounded.

[0208] 37 to 42, the connection member 60 includes a first portion 60a and a second portion 60b. The first portion 60a is used to connect the second portion 60b and the fifth terminal / additional terminal 135a of the chip 20. The second portion 60b is used to connect the metal member 96 and the first portion 60a.

[0209] The chip 20 is connected to the first portion 60a. When the ink cartridge is mounted in the mounting portion 90, each communication terminal of the chip 20 is connected to the first contact pin 911 to the fourth contact pin 914 of the contact pin assembly 52. ​​The shapes of the first portion 60a and the second portion 60b are not limited, and may be designed to have a regular shape such as a rectangle, or may be designed to have a zigzag or other irregular shape. The first portion 60a may be formed integrally, or may be formed by joining multiple metal pieces.

[0210] Furthermore, the connecting member 60 may be an integral structure that does not have the first portion 60 a and the second portion 60 b. When the conductive member includes the first portion 60 a and the second portion 60 b, the structure of the first portion 60 a may be simplified, and the second portion 60 b may have a more complex structure.

[0211] For example, the second portion 60b may be used as the handle 30 of the ink cartridge, functioning as a handle for mounting and removing the ink cartridge in the tray 97, making it easier for the user to mount and remove the ink cartridge. This configuration not only realizes the transmission of a ground signal, but also simplifies the structure of the ink cartridge (reducing the production, manufacturing, and assembly of handle parts). Therefore, this structure reduces the number of parts, simplifies the structure of part of the ink cartridge, and reduces costs.

[0212] Furthermore, the first portion 60a of the connection member 60 includes a first connection portion 60aa and a second connection portion 60ab. The first connection portion 60aa is used to connect to the fifth terminal or additional terminal 135 of the chip 20. The second connection portion 60ab is used to connect to the second portion 60b.

[0213] The second portion 60b includes a first connecting portion 60ba and a second connecting portion 60bb. The second connecting portion 60bb is used to connect to the second connecting portion 60ab. The first connecting portion 60ba is used to abut against the metal member 96.

[0214] Specifically, the first connection portion 60ba abuts against the surface of the metal member 96 on the +Z axis to transmit a ground signal. The first connection portion 60ba does not necessarily have to be located at the end of the second portion 60b. As shown in FIGS. 41 and 42, the first connection portion 60ba is provided in the center of the second portion 60b. The first connection portion 60ba may be located at one or a combination of multiple positions.

[0215] As shown in FIG. 41 , the first connection portion 60ba may be located in three different positions. Because the second portion 60b functions as a handle in addition to abutting the metal member 96, the first connection portion 60ba is located closer to the -Z axis direction than the second portion 60b in the Z axis direction. In the Z axis direction, the first connection portion 60ba is located closer to the -Z axis direction than the second connection portion 60bb. The second portion 60b is located closer to the -Z axis direction than the first portion 60a. The first portion 60a is located closer to the -Z axis direction than the chip 20. In other words, the portion that abuts the metal member 96 is located at the top.

[0216] In the Y-axis direction, the first connection portion 60ba is located on the -Y-axis direction side of the second connection portion 60bb, the second portion 60b is located on the -Y-axis direction side of the first portion 60a, and the first portion 60a is located on the -Y-axis direction side of the chip 20. In other words, the first connection portion 60ba is located on the -Z-axis and -Y-axis direction side of the second connection portion 60bb, the second portion 60b is located on the -Z-axis and -Y-axis direction side of the first portion 60a, and the first portion 60a is located on the -Z-axis and -Y-axis direction side of the chip 20.

[0217] The metal member 96 that the second portion 60b comes into contact with may be a conductive metal member located anywhere in the printer. Preferably, the metal member 96 that the second portion 60b comes into contact with is located at the top of the ink cartridge 10 along the Z-axis direction.

[0218] As shown in Figures 34 and 37, when an ink cartridge is mounted in the mounting portion 90, the position of the assembly in the mounting portion is limited by the engagement of columnar positioning portions 93f, 93s with positioning holes 97a, 97b in the tray 97 and holes 42a, 42b in the ink cartridge. An ink injection tube 92 (corresponding to the ink supply portion 92 in the first embodiment) fits into the ink outlet 41 to provide ink for printing by the printer. A contact pin assembly 91 contacts the chip 20 to provide signal transmission to the chip.

[0219] The protrusion on the locking portion 94 is used to engage with a groove on the bottom of the tray 97 to secure the assembly consisting of the ink cartridge and the tray 97. The connecting member 60 contacts the metal member 96 to transmit a ground signal. The connecting member 60 functions as a handle for installation and removal when the ink cartridge is being installed in the tray 97, making it easier for the user to install and remove the ink cartridge.

[0220] The number and shape of the positioning holes 97a / 97b in the tray 97 and the holes 42a / 42b in the ink cartridge are not limited. For example, the number of positioning holes may be one or more, and the shape may be circular, rectangular, or other irregular, as long as it allows stable attachment to the printer and stable installation to the ink cartridge.

[0221] 37 to 40, the ink cartridge in this embodiment has a print head 40 and an ink bag 10a in which ink is stored. Here, the chip 20 and the connecting member 60 are provided on the print head 40. Here, an ink outlet 41 is provided on the +X side of the print head 40, and the ink outlet 41 communicates with the ink bag 10a via an outflow path therein, so that the ink stored inside the ink bag 10a can be supplied to the printer via the ink outlet 41.

[0222] As shown in FIG. - A shaft hole is provided on the Z-axis side, and the shaft of the second portion 60b is attached so as to fit into the shaft hole. - Further provided on the Z-axis side is a support member 102 that is located on the +Z-axis side of the second portion 60b and on the -Y-axis side of the shaft hole, and that supports at least a portion of the second portion 60b.

[0223] Specifically, in this embodiment, the support member 102 is - A protrusion extending in the Z-axis direction, - Along the Z-axis direction, the support member 102 is higher than the axis, and when the ink cartridge is installed, at least a part of the second portion 60b contacts the support member 102 and is higher than the support member 102. - Located on the Z-axis side.

[0224] Therefore, in the mounted state, the second portion 60b is tilted toward the -Y axis and the -Z axis due to the action of the support member 102, and the -Z axis end of the second portion 60b comes into contact with the metal member 96 above the ink cartridge, thereby achieving an electrical connection. Therefore, the first connection portion 60ba can be positioned on the -Z axis and -Y axis sides of the second connection portion 60bb, and the second portion 60b can be positioned on the -Z axis and -Y axis sides of the first portion 60a.

[0225] This configuration reduces the risk of electric shock due to unstable grounding, improves the stability of the chip grounding, and improves the safety of chip use. It also makes it easier for users to install and remove ink cartridges.

[0226] There are no limitations on the number and shape of the support members 102. Specifically, one or two or more support members 102 may be provided, and the support members 102 may be provided in the shape of a rectangular parallelepiped, a cylindrical or triangular prism, or any other regular or irregular shape, as long as they can support the second portion 60b and stabilize contact with the metal member 96.

[0227] Preferably, along the X-axis direction, the contact area between the second portion 60b and the metal member 96 is closer to the left surface 120c of the chip substrate 120 than to the right surface 120d of the chip substrate 120. Preferably, the contact area between the second portion 60b and the metal member 96 may be provided within the range of the first region R1, rather than the first connection portion 60ba shown in FIG.

[0228] 41, the connection portion between the second portion 60b and the metal member 96 is the third connection portion 60bc. The third connection portion 60bc is located in the first region R1, and the second portion 60b is provided so as to be inclined in the X-axis direction (the inclination is achieved by the difference in height of the multiple support members 102), and the third connection portion 60bc is located at the +Z-axis end of the second portion.

[0229] In the process of mounting the ink cartridge 10 to the printing device, first the connection member 60 (conductive member) and the ground member come into contact, and then the chip 20 and the contact pin assembly 91 come into contact.

[0230] Example 3 of embodiment 3. In Example 3, a new conductive member is provided based on Example 2. One end of this conductive member is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least a portion of the wall of the mounting chamber, and the two electrical connection positions are above the chip.

[0231] As shown in FIGS. 43 and 44, the chip according to this embodiment is different from the chip according to the above embodiment in that one recess 21 is provided in the chip 20. 2 The function of the recess 21 is to avoid the fifth contact pin 915 and prevent the fifth contact pin 915 from abutting or coming into contact with the chip 20. In other words, when the ink cartridge 10 is installed in the installation portion of the printer, a portion of the fifth contact pin 915 is located within the recess 21, but the fifth contact pin 915 does not abut or come into contact with the chip 20.

[0232] It should be noted that chip 20 does not have to have recess 21. If there is no terminal / contact portion in the X-axis direction of the chip that can be connected to fifth contact pin 915, even if chip 20 and fifth contact pin 915 come into contact with each other, they will not be electrically connected and a ground signal will not be transmitted.

[0233] As shown in Figures 45 to 51, the ink cartridge 10 includes a chip 20, a connecting member 70 (corresponding to the conductive member in the first embodiment), a print head (also referred to as a base) 40, and an ink bag 10a. The chip 20 is provided on the front end side in the mounting direction D2 of the ink cartridge 10. The connecting member 70 is configured as a conductive member and is made of a conductive material. One portion is connected to the chip 20, and another portion is connected to a metal member 96 (corresponding to the ground member in the first embodiment) of the mounting portion 90. For example, the connecting member 70 is connected to a lower surface 96a of the metal member 96 in the +Z-axis direction. That is, the connecting member 70 is connected to a lower surface 96a of the metal member 96 (corresponding to the ground member in the first embodiment) facing the mounting portion 90.

[0234] The ground signal between the chip 20 and the printer is transmitted by the connecting member 70 and the metal member 96. According to the above invention, the ground signal is transmitted to the chip 20 by the metal member 96 and the connecting member 70, improving stability and reducing situations where the chip cannot be grounded or the ground becomes unstable.

[0235] Furthermore, in this embodiment, the first terminal 131 to the fourth terminal 134 are provided on the front surface 120a of the chip 20, and the fifth terminal 135 is provided on the rear surface 120b of the chip 20. The multiple terminals 130 (the first terminal 131 to the fifth terminal 135) are provided within a first region R1 of the −X axis of the chip 20. Because the first region R1 is located on the −X axis side of the chip, the terminals on the chip 20 are arranged compactly. Because the fifth terminal 135 that transmits a ground signal and the communication terminals (the first terminal 131 to the fourth terminal 134) that transmit a high-level signal are arranged on different surfaces of the chip 20, the possibility of a short circuit between them is reduced, and electromagnetic interference between them is avoided.

[0236] Also, as shown in FIGS. 45 and 46, the connection member 70 according to this embodiment is a single, integrally molded member, which is also different from the above-described embodiment. 2The material may be a metal profile made of low-carbon steel or high-carbon steel, and the surface may be nickel-plated or chrome-plated to prevent rust. The material may also be a metal profile made of stainless steel.

[0237] The cross section of the connection member 70 may be circular, oval, rectangular, square, trapezoidal, or the like. The manufacturing process may be hot or cold forming. For example, a conductive member as shown in FIG. 45 is manufactured by thermally deforming a 0.6 mm diameter, nickel-plated 82B high carbon steel metal wire using a spring machine. In this embodiment, the material, mold material, manufacturing process, etc. of the conductive member are not limited as long as stable transmission of the ground signal is ensured.

[0238] For example, if the cross section of the molded material is circular, it may be a metal wire with a diameter of 0.3 to 2.5 mm. Preferably, the conductive member is a metal wire with a diameter of 0.5 to 1.0 mm, and the metal wire's elasticity and shape stability must meet certain conditions. If the cross section of the metal wire has a relatively small diameter, it may not be able to stably maintain its original shape, and may not be able to maintain its original shape after the ink cartridge 10 has been installed several times, which may affect the smooth transmission of the ground signal. If the diameter of the metal wire is relatively large, it may not be possible to smoothly install or remove the ink cartridge 10.

[0239] When the metal wire is non-circular, the conductive member may be a metal shaped material having a width of 0.3 to 2.5 mm, preferably 0.5 to 1.0 mm. When the cross section of the shaped material is circular, elliptical, or the like, and the main surface is arc-shaped, a single contact plane may be formed by polishing at the position of fourth portion 704 (for example, the position indicated by the dotted line in FIG. 45) so that the portion connected to lower surface 96a of metal member 96 on the +Z axis becomes first contact portion 70a.

[0240] The contact plane 70a' can be ground around the original first contact portion 70a. Specifically, by grinding a small flat surface (for example, at the position indicated by the dotted line in FIG. 45) with a grinding machine, the portion that will connect with the metal member 96 can be made into the first contact portion 70a. Because the contact between the connecting member 70 and the metal member 96 is surface contact rather than point contact, the impact of vibrations generated during printer operation or external vibrations on the contact stability between the connecting member 70 (corresponding to the conductive member in the first embodiment) and the metal member 96 can be reduced, which is advantageous for improving contact stability and stable transmission of ground signals. The contact plane 70a' may be a small flat surface (referred to as the first contact portion 70a) extruded from the original first contact portion 70a.

[0241] The connecting member 70 in this embodiment includes a first contact portion 70a, a second contact portion 70b, a semi-closed ring 70c, a first curved space 70d, a second curved space 70e, a third curved space 70f, and a fourth curved space 70g. According to the bending state of the profile, the connecting member 70 is divided into a first portion 701, a second portion 702, a third portion 703, a fourth portion 704, a fifth portion 705, a sixth portion 706, a seventh portion 707, an eighth portion 708, a ninth portion 709, a tenth portion 710, and an eleventh portion 711, in order.

[0242] Here, the second portion 702, the fourth portion 704, the sixth portion 706, the seventh portion 707, the eighth portion 708, and the tenth portion 710 are curved regions. The first contact portion 70a is located at the fourth portion 704, and when observed in the Z-axis direction, the first contact portion 70a is located at the end of the connecting member 70 in the -Z-axis direction and abuts against the lower surface 96a of the metal member 96 in the +Z-axis direction. The first contact portion 70a is located further in the -Z-axis direction than the second contact portion 70b.

[0243] The fourth portion 704 is located closer to the -Z axis than other portions of the connecting member 70. The semi-closed ring 70c is located on the -Y axis side of the connecting member 70, and is a space formed by the first portion 701, the second portion 702, the third portion 703, the fourth portion 704, and the fifth portion 705. The third portion 703 and the fifth portion 705 are inclined in different directions, and when observed along the Y axis direction, the third portion 703 is inclined toward the -Z axis direction, and the fifth portion 705 is inclined toward the +Z axis direction.

[0244] That is, the third portion 703 is inclined toward the +Y-axis and -Z-axis directions, and the fifth portion 705 is inclined toward the +Y-axis and +Z-axis directions. The third portion 703, the fourth portion 704, and the fifth portion 705 together form a single peak shape, and the fourth portion 704 is located closest to the -Z-axis side. At least a part of the fifth portion 705 is located on the -Z-axis side of the sixth portion 706 to the eleventh portion 711.

[0245] When the ink cartridge 10 is installed in the mounting portion 90, the fifth portion 705 first contacts the metal member 96 (if a mounting portion protection member is provided in the printer in the -Y axis direction of the metal member 96, the fifth portion 705 first contacts the mounting portion protection member, and after passing the mounting portion protection member, the fifth portion 705 contacts the metal member 96). As the ink cartridge 10 advances along the installation direction D2, the -X axis side of the connecting member 70 and the semi-closed ring 70c are compressed and deformed to a certain extent until the entire connecting member 70 enters the interior of the mounting portion 90 (at which point the first contact portion 70a abuts against the underside 96a of the metal member 96). During the installation process, the fifth portion 705 guides the installation of the connecting member 70 in the mounting portion 90, guides the deformation of the connecting member 70, and ultimately functions to bring the first contact portion 70a and the metal member 96 into contact.

[0246] When the ink cartridge 10 is removed from the mounting portion 90, the first contact portion 70a does not separate from the metal member 96 as the chip 20 tries to separate from the printer's contact pin assembly 91, and when the ink cartridge 10 is completely removed from the mounting portion 90, the first contact portion 70a separates from the metal member 96.

[0247] Furthermore, as the ink cartridge 10 is removed in the direction opposite to the mounting direction D2 before the first contact portion 70a separates from the metal member 96, the third portion 703 performs the functions of a guide and a buffer, preventing the connecting member 70 from getting caught on the protective member of the metal member 96 as the ink cartridge 10 separates from the mounting portion 90, thereby allowing the ink cartridge 10 to be removed smoothly.

[0248] With this configuration, the connecting member 70 returns to its initial state due to its own elasticity when the ink cartridge 10 is separated from the mounting portion 90. The connecting member 70 has an initial state (when the connecting member 70 is not mounted in the mounting portion 90) and an abutting state (when the connecting member 70 is mounted inside the mounting portion 90), which ensures good contact between the connecting member 70 and the metal member 96 and prevents situations where the contact becomes unstable.

[0249] The seventh portion 707 and the eighth portion 708 are each bent into a U-shaped structure that opens toward the +Z axis direction, and can be joined to the first edge 403 and the second edge 404 of the print head 40 to function as fixing the conductive member. This allows the connecting member 70 to withstand pressure from the metal member 96 to the portion of the conductive member 70 on the -Y axis side, and pressure from the chip 20 to the second contact portion 70b, and also ensures the elastic recovery force of the connecting member 70 and the ability to switch between the initial state and the abutting state of the connecting member 70.

[0250] A third curved space 70f having a U-shaped structure that opens toward the -Z axis direction is formed between the seventh portion 707 and the eighth portion 708. The print head 40 may be provided with several movable locking devices that can engage with the third curved space 70f to prevent the connecting member 70 from detaching from the print head 40.

[0251] The second contact portion 70b is formed on the tenth portion 710, and the second contact portion 70b abuts against the fifth terminal 135 of the chip 20. The chip 20 can apply a certain amount of pressure to the second contact portion 70b to improve contact between the second contact portion 70b and the fifth terminal 135. The tenth portion 710 can have a bent corner polished to form a small flat surface, which forms the second contact portion. This can further stabilize the contact between the connecting member 70 and the chip 20.

[0252] As shown in Figures 43 to 46, when the ink cartridge 10 is observed along the -Y-axis direction, i.e., when the connecting member 70 is not misaligned in the X-axis direction, the projection of the connecting member 70 is in a straight line perpendicular to the X-axis. Therefore, the projection of the first contact portion 70a onto the chip 20 is located on the fifth terminal 135, the projection of the first contact portion 70a onto the chip 20 is located within the first region R1, and the projection of the first contact portion 70a onto the chip 20 is located on the -X-axis side of the chip 20. The presence of the eleventh portion 711 prevents the connecting member 70 from scratching the fifth terminal 135 during the manufacturing process, thereby avoiding damage to the fifth terminal 135.

[0253] 47 and 48, the ink cartridge 10 further includes a chip mounting portion 201. The chip mounting portion 201 is used to mount the chip 20. The chip 20 is fixed to the ink cartridge 10 via the chip mounting portion 201. The chip mounting portion 201 includes a through groove 2011, a storage portion 2012, a flat surface 2013, a positioning pillar 2014, and a fixing portion 2015.

[0254] The flat surface 2013 is in close contact with the rear surface 120b of the chip 20 and is used to position the chip 20. The receiving portion 2012 is used to receive the memory 100. The positioning posts 2014 fit into the first to fourth holes of the chip 20, thereby ensuring that the chip 20 is fixed to the chip mounting portion 201. The connecting member 70 passes through the through groove 2011 and abuts against the fifth terminal 135 of the chip 20. As shown in FIG. 31 , all or at least a portion of the ninth portion 709, tenth portion 710, and eleventh portion 711 of the connecting member 70 are received in the through groove 2011.

[0255] The fixing portion 2015 is a protrusion provided on the chip mounting portion 201, and is used to fit into a fixing groove 451 in the print head 40 and fix the chip mounting portion 201. The fixing portion 2015 may be provided with several locking devices that can be used to engage with the fixing groove 451. This configuration can reduce the likelihood of the chip mounting portion 201 becoming detached from the print head 40 due to the elastic force of the connecting member 70.

[0256] The print head 40 has an upper surface 40a on the -Z axis side, a protrusion, and a mounting portion 45. The protrusion is located on the -Y axis side of the upper surface 40a. The protrusion may have only a first protrusion 43 (as shown in FIG. 50 ), or may have a first protrusion 43 and a second protrusion 44 (as shown in FIG. 50 ). When the protrusion has the first protrusion 43 and the second protrusion 44, the first protrusion 43 and the second protrusion 44 can function as gripping portions when the user installs the ink cartridge 10 in the tray 97 along the installation direction D1 or removes the ink cartridge 10 in the direction opposite to the installation direction D1. The user can move the ink cartridge 10 by gripping the sides of the first protrusion 43 and the second protrusion 44, making it easier to install and remove the ink cartridge 10.

[0257] The print head 40 further includes a first protrusion 401, a second protrusion 402, a first ridge 403, a second ridge 404, and a fixing groove 451. The fixing groove 451 is used to fix the chip mounting portion 201. When the connecting member 70 is attached to the print head 40, the first protrusion 401 is located within the semi-closed ring 70c of the connecting member 70, which can reduce the occurrence of a situation in which the connecting member 70 becomes detached from the print head 40.

[0258] The second protrusion 402 is located within the first curved space 70d of the connecting member 70, reducing the likelihood of the connecting member 70 becoming detached from the print head 40. The first edge 403 and the seventh portion 707 may be fitted together, providing a tight fit between them, reducing the likelihood of the connecting member 70 becoming detached from the print head 40. The second edge 404 and the eighth portion 708 may be fitted together, providing a tight fit between them, reducing the likelihood of the connecting member 70 becoming detached from the print head 40. The print head 40 may be provided with several movable locking devices, which can engage with the third curved space 70f to prevent the connecting member 70 from becoming detached from the print head 40.

[0259] The first protrusion 401 has an inclined surface 401a on the -Z axis side. The second protrusion 402 has an inclined surface 402a on the -Z axis side. The first edge 403 has an inclined surface 403a on the -Z axis side. The second edge 404 has an inclined surface 404a on the -Z axis side. The inclined surfaces function as guides when attaching the connecting member 70 to the print head 40.

[0260] Furthermore, as shown in Figure 52, in this embodiment, the print head 40 of the ink cartridge 10 is provided with widening members 46 on the +X axis side and the -X axis side. This increases the width of the ink cartridge 10 in the X axis direction, which is advantageous for increasing the width of the ink bag 10a and the ink capacity of the ink bag 10a. Naturally, the tray 97 also increases in width in the X axis direction. In this embodiment, in the process of installing the ink cartridge 10 in the printing device, first, the connecting member 70 (the conductive member) contacts the ground member, and then the chip 20 contacts the contact pin assembly 91.

[0261] Example 4 of Embodiment 3 In Example 4, a ground wire type conductive member is provided based on the above-mentioned Examples, in which one end of the conductive member is electrically connected to the ground terminal of the chip, and the other end extends downward and is electrically connected to the conductive swing rod, with the electrical connection position between the two located below the chip and further connected to the ground member via the conductive swing rod.

[0262] 53 and 54, the ink cartridge body 50 further includes a bottom housing 51 (corresponding to the print head 40 in Examples 2 and 3), and at least a portion of the connecting member 70 is provided on the front end side of the front surface 51a in the mounting direction D2 (+Y-axis direction), and a space Q is formed between the connecting member 70 (corresponding to the conductive member) and the front surface 51a, and the space Q can accommodate a portion of the mounting portion 90. At least a portion of the connecting member 70 is below the bottom surface 51b of the ink cartridge 10.

[0263] Furthermore, as shown in FIG. 55, the connecting member 70 is configured as a first conductive piece, and a conductive rocking rod is provided at the bottom of the accommodating chamber. The conductive rocking rod is located at the bottom of the ink cartridge body and can position the ink cartridge body. In this embodiment, the locking portion 94 is a rod-shaped member that can be rocked and reset, that is, the locking portion 94 is configured as a conductive rocking rod. The upper surface of the locking portion 94 can be electrically connected to the first conductive piece. The electrical connection position between the two is below the tip.

[0264] According to the above invention, by utilizing the space Q between the connecting member 70 and the front surface 51a to restrict the position of the mounting portion 90, the connecting member 70 and the locking portion 94 can come into contact only when the space Q and the mounting portion 90 are properly assembled, and the ground signal of the chip 20 can be transmitted normally only when the connecting member 70 and the locking portion 94 are in contact.

[0265] Furthermore, the space Q can also accommodate a portion of the connecting member 70. For example, one side of the connecting member 70 can be formed in an "n" shape, with a portion of the connecting member 70 also disposed within the space Q. As shown in FIG. 56, the connecting member 70 further includes an extension 710, which is disposed within the space Q and between the space Q and the front surface 51a. In such a structure, the space Q is still provided between the connecting member 70 and the front surface 51a. As long as a portion of the connecting member 70 fits this description, it can be said to meet the characteristic that the space Q is formed between the connecting member 70 and the front surface 51a.

[0266] A space Q formed between the connecting member 70 and the front surface 51a can accommodate the front wall 97aa of the tray 97. The space Q and the front wall 97aa limit the position of the conductive member, and the conductive member itself comes into contact with the grounding member. Furthermore, a bottom wall 97bb is provided at the bottom of the accommodation chamber, and the grounding member may be the bottom wall 97bb of the accommodation chamber.

[0267] 53 to 56, one portion of the connection member 70 is connected to the chip 20, and the other portion is connected to the ground member of the mounting portion 90. The connection member 70 serves both as a mechanical means and as a chip signal detection means to ensure that the ink cartridge is mounted correctly in the mounting portion 90 of the printer.

[0268] The space Q between the connecting member 70 and the front surface 51a engages with the front wall 97aa of the tray 97, ensuring that the tray 97 and ink cartridge 10 are correctly installed and secured only when the front wall 97aa is within the space Q. When the assembly is installed in the installation portion 90, the connecting member 70 contacts the upper surface of the locking portion 94, detecting the chip model number and ensuring that the ink cartridge 10 is correctly detected by the chip signal detection means. The integration of the mechanical means and the chip signal detection means further ensures that the ink cartridge is correctly installed in the printer.

[0269] Furthermore, the ink cartridge 10 includes a chip 20, a bottom housing 51, an ink bag 10a, a connecting member 70, holes 220 and 210, a front surface 51a located in the +Y-axis direction, a bottom surface 51b located in the +Z-axis direction, and an ink outlet 41. The tray 97 includes a front wall 97aa and positioning holes 971 and 972.

[0270] The locking portion 94 has an upper surface 94a in the -Z axis direction. When the ink cartridge 10 is mounted in the mounting portion 90, the ink supply portion 92 (ink injection tube) fits into the ink outlet 41 to supply ink for printing by the printer. The printer's contact pin assembly 91 contacts the communication terminal of the chip 20 and provides chip signal transmission.

[0271] The columnar positioning portions 93f, 93s, the positioning holes 971, 972 in the tray 97, and the holes 220, 210 in the ink cartridge engage with each other to restrict the position of the assembly in the mounting portion. A protrusion 941 in the locking portion 94 engages with a groove in the bottom of the tray 97 to secure the assembly consisting of the ink cartridge 10 and the tray 97. The connecting member 70 transmits a ground signal by engaging with the front wall 97aa of the tray 97 and contacting the top surface 94a of the locking portion 94.

[0272] Example 5 of Embodiment 3 Based on the above embodiment, this embodiment provides another antenna-type conductive member, where the conductive member is composed of a conductive piece and a part of the conductive film of the ink bag, as follows:

[0273] The conductive member according to this embodiment includes a first conductive piece 71 and a first conductive transmission medium. The ink cartridge body includes an ink storage section, which includes an ink chamber surrounded by a film layer structure. The film layer structure includes an insulating outer film, a conductive intermediate film, and an insulating inner film, which are stacked in this order from the outside to the inside. The conductive intermediate film is configured as the first conductive transmission medium, and at least a portion of the conductive intermediate film is used to electrically connect the first conductive piece to the upper wall of the chamber.

[0274] 57 and 58, the ink cartridge in this embodiment has an ink storage section provided in the ink cartridge body, and the ink storage section is configured as an ink bag 10a. The ink bag 10a has an ink storage chamber surrounded by a film layer structure, and this ink storage chamber is used to store ink.

[0275] For example, the ink bag has an upper surface and a lower surface, and the upper surface and the lower surface are outer surfaces of the film layer structure. The film layer structure includes an insulating outer film, a conductive intermediate film, and an insulating inner film, arranged in this order from outside to inside. The insulating outer film forms the outer surface of the ink bag, and the outer surface includes the above-mentioned upper surface and lower surface. The insulating inner film forms the inner surface of the ink bag and contacts the ink. The conductive intermediate film is provided between the insulating outer film and the insulating inner film, and at least a portion of the conductive intermediate film functions as a first conductive transmission medium and is considered to be part of the conductive member. Furthermore, a portion of the conductive intermediate film can be electrically connected to a ground member.

[0276] In an embodiment of the present application, a portion of the conductive intermediate film is exposed on the outer surface of the film layer structure to form a first electrical connection. The first electrical connection can be electrically connected to a first conductive piece, and the other end of the first conductive piece is electrically connected to a ground terminal of the chip. For example, the insulating outer film has a first openwork portion, the first openwork portion is disposed adjacent to the first conductive piece, and a portion of the conductive intermediate film is exposed in the first openwork portion to form the first electrical connection.

[0277] A portion of the conductive intermediate film is exposed on the outer surface of the film layer structure to form a second electrical connection portion. The second electrical connection portion faces the first electrical connection portion and is electrically connected to the first electrical connection portion via the unexposed conductive intermediate film therebetween. The second electrical connection portion is electrically connected to the ground member.

[0278] For example, the insulating outer film may have a second open section, and at least a portion of the conductive intermediate film may be exposed within the second open section to form a second electrical connection. The second electrical connection is electrically connected to the first electrical connection through a portion of the conductive intermediate film to transmit a ground signal. That is, the ground signal between the chip and the printer is transmitted through the first conductive piece, the intermediate conductive film, and the grounding member. This configuration improves the stability of the ink cartridge ground and reduces the risk of poor or unstable grounding.

[0279] Based on the above embodiment, in this embodiment, the grounding member may be the outer casing of the mounting part 90 (the outer casing in the +Z-axis, -Z-axis, +X-axis, -X-axis, and +Y-axis directions) or a part of the outer casing. For example, the wall of the storage chamber is formed as the grounding member, the first electrical connection portion is provided on one side of the Y-axis of the ink bag 10a, the second electrical connection portion is located on one side of the -Y-axis of the ink bag, and the second electrical connection portion is located on the -Z-axis side of the first electrical connection portion, i.e., the second electrical connection portion is located closer to the wall of the storage chamber than the first electrical connection portion.

[0280] The film layer structure in a portion of the surface of the ink bag 10a has four layers. Along the direction from the outside to the inside of the ink bag 10a, the first film layer is made of PET and is therefore also called a PET film, i.e., an insulating outer film; the second film layer is made of Al and is therefore conductive and is also called an aluminum film, metal film, or intermediate conductive film 10a1; the third film layer is a nylon film; and the fourth film layer is made of PET140 and is therefore also called a PET140 film.

[0281] Other areas on the surface of the ink bag 10a are covered only with three layers of film. These areas are exposed to the outer surface of the film layer structure, and the aforementioned conductive film 10a1, nylon film, and PET140 film are arranged in this order from the outside to the inside of the ink bag 10a. Because the conductive film 10a1 is located on the outermost layer in these areas, these areas are also referred to as the conductive areas of the ink bag 10a. In other words, the conductive areas form electrical connections. The conductive films 10a1 in all areas of the ink bag 10a are interconnected; that is, the ink bag 10a has the same conductive film 10a1 whether it is a three-layered area or a four-layered area. At the same time, the conductive film 10a1 is isolated from the ink stored in the ink bag 10a. Therefore, in this embodiment, the ink does not participate in the transmission of ground signals.

[0282] In this embodiment, a portion of the first conductive piece 71 is connected to the chip 20, and another portion is connected to the conductive film (first electrical connection portion) of the conductive region A of the ink bag 10a. The first conductive piece 71 has a first portion 71a and a second portion 71b. The first portion 71a is connected to the chip 20, and the second portion 71b is connected to the conductive film.

[0283] After the conductive film of the conductive area A and the first conductive piece 71 are connected, the -Z axis side of the connection between them can be covered with a PET film to improve the appearance of the ink cartridge 10. Alternatively, the connection between them can be fixed with an adhesive material (such as tape) to make the connection between the first conductive piece 71 and the first electrical connection portion more stable.

[0284] 59, in this embodiment, the end portion on the -Y-axis side of the ink bag 40 extends in the -Z-axis direction, and a conductive area B exists on the surface on the -Z-axis side of the end portion, and this conductive area is the second electrical connection portion. The conductive film 10a1 of the conductive area B is connected to a metal member 96 of the outer casing on the +Z-axis side of the mounting portion 90, and further, this metal member 96 forms the wall of the containing chamber. This realizes transmission of a ground signal between the chip 20 and the printer 1.

[0285] In addition, a conductive region can be provided at any location on the ink bag 10a, and the conductive film in that region can be connected to the metal member 96 of the mounting portion 90. For example, in addition to the end on the -Y axis side of the ink bag 10a, the conductive film on the +Y axis side, +X axis side, -X axis side, -Z axis side or +Z axis side of the ink bag 10a can also be connected to the metal member 96 of the mounting portion 90.

[0286] As shown in Figures 60 and 61, based on the above example, the ink cartridge according to the embodiment of the present application further includes a second conductive piece 72, and the second conductive piece 72 and the first conductive piece 71 are spaced apart. The second conductive piece 72 also has a first portion 72a and a second portion 72b. The first portion 72a is connected to the conductive film in the conductive region C of the ink bag 10a, and the second portion 72b is connected to the metal member 96 of the mounting portion 90. A ground signal is transmitted to the chip 20 via the metal member 96, the second conductive piece 72, the conductive film, and the first conductive piece 71. The end of the ink bag 40 on the -Y axis side does not directly contact the metal member of the mounting portion 90.

[0287] Optionally, after the conductive film of the conductive region C and the second conductive piece 72 are connected, the -Z axis side of the connection between them can be covered with a PET film to improve the appearance of the ink cartridge 10. Alternatively, the connection between the second conductive piece 72 and the conductive film 10a1 can be made more stable by fixing the connection between them with an adhesive material (such as tape).

[0288] In the above embodiment, the metal members of the mounting unit 90 may be the outer casing of the mounting unit 90 (the outer casing in the +Z-axis, -Z-axis, +X-axis, -X-axis, and +Y-axis directions) or a part of the outer casing. For the safety of the user, all of the metal members of the mounting unit 90 are grounded, and all share a common ground signal with the printer.

[0289] In this embodiment, the second conductive piece 72 first extends in the -Z axis direction from the conductive area C of the ink bag 10a, then extends to the -X axis side or the +X axis side to cross the tray 97, and then extends in the +Z axis direction to connect with the outer housing on the +Z axis side of the mounting portion 90.

[0290] The number of second conductive pieces 72 is not limited, and may be one or more. The position of the second conductive piece 72 on the ink bag 10a is also not limited, and may be, for example, on the upper or lower surface of the ink bag 10a, or on the +X-axis side, -X-axis side, +Y-axis side, or -Y-axis side of the ink bag 10a.

[0291] Example 6 of Embodiment 3 62 is a schematic diagram of an ink cartridge of Example 6 according to Embodiment 3 of the present application. The description of the ink cartridge of this example is the same as that of Example 4 of Embodiment 3, and the chip is Chip Variation 1 or Chip Variation 3, so detailed description will be omitted here.

[0292] Example 7 of Embodiment 3 63 is a schematic diagram of an ink cartridge of Example 7 according to Embodiment 3 of the present application. The description of the ink cartridge of this example is consistent with the contents of Examples 1 to 3 of Embodiment 3, and the chip is Chip Variation 1 or Chip Variation 3, so detailed description will be omitted here.

[0293] Embodiment 4 Based on the first embodiment, the present embodiment further includes a conductive support plate 82, and the mounting portion 90 is slidably mounted on a rail 86. A barrier plate 85 is provided between the rail 86 and the conductive support plate 82. The conductive support plate 82 is provided on the opposite side of the mounting portion of the barrier plate 85, and the length direction of the conductive support plate 82 coincides with the extension direction of the rail 86. For example, the conductive support plate 82 is provided parallel to a horizontal plane, and the conductive support plate 82 is disposed on both sides of the ground rail 80 so as to face the conductive wall plate 81. Correspondingly, the conductive member includes a bridge connection portion that straddles the barrier plate 85. That is, the bridge connection portion is provided above the barrier plate 85, and the portion of the bridge connection portion close to the conductive support plate contacts the conductive support plate to be electrically connected.

[0294] 66, rail 86 may be a conductive member having a ground signal, or may be a non-conductive member having no ground signal. If rail 86 has a ground signal, conductive support plate 82 may be a part of the rail, or rail 86 and conductive support plate 82 may be two different members. Because barrier plate 85 is a non-conductive member having no ground signal (e.g., barrier plate 85 is made of non-conductive plastic), in this embodiment, the conductive member must straddle barrier plate 85 to abut conductive support plate 82 and achieve the beneficial effect of the present application.

[0295] Specifically, as shown in Figures 64 and 65, in this embodiment, chip 20 is provided on the front end side of ink cartridge 10 in the mounting direction, and memory 100 is provided on rear surface 120b of chip 20. Conductive piece 140a is provided between chip 20 and ink cartridge 10, and the shape of conductive piece 140a roughly matches the shape of chip 20, with opening 111 provided in the center of conductive piece 140a that matches the shape of memory 100. Opening 111 is just large enough to allow the protruding portion of memory 100 to pass through, and ground terminals 137a, 137b are connected so as to be in close contact after attachment of chip 20 and conductive piece 140a is complete.

[0296] The connecting member 140 is configured as a conductive member, and the connecting member 140 (corresponding to the conductive member) is made of a conductive material having a certain hardness. One end of the connecting member 140 (corresponding to the conductive member) is connected to the conductive piece 140a via solder. Of course, the connecting member 140 and the conductive piece 140a may be an integrally molded sheet metal part, or may be a structure formed by connecting multiple parts. Optionally, in this embodiment, the conductive piece 140a may not be provided, and the connecting member 140 (corresponding to the conductive member) may be directly connected to a ground terminal, thereby similarly achieving transmission of a ground signal.

[0297] 66 to 70, the other end of the connecting member 140 extends along the first side wall 50a of the ink cartridge body 50 in the -Y axis direction, or along the second side wall (located opposite the first side wall 50a, not shown) of the ink cartridge body in the +Y axis direction, or along the top wall 50d of the ink cartridge body in the +Z direction, to the rear side wall of the ink cartridge 10 in a direction away from the chip 20. Near the end of the connecting member 140, the connecting member 140 is bent in a direction away from the surface of the ink cartridge 10, forming a bridge connection portion 140b which is connected to the conductive support plate 82 of the ground rail. Furthermore, a ground signal between the chip 20 and the printer is transmitted by the conductive piece 140a, the connecting member 140, and the conductive support plate 82.

[0298] The rail 86 is a member for placing the mounting portion 90, and for the safety of the user, a ground signal is shared between the rail 86 and the printing device. The conductive support plate 82 is a metal member of the printing device, and for the safety of the user, a ground signal is shared between the conductive support plate 82 and the printing device. With this configuration, according to the above invention, the ground signal is transmitted to the chip 20 by the conductive support plate 82 and the connecting member 140, improving stability and reducing situations in which grounding is not possible or the grounding is unstable, thereby achieving the beneficial effects of the present application.

[0299] Based on the above embodiment, in the present embodiment, a contact portion is provided at one end of the conductive member close to the ground member, and the contact portion is configured to contact the conductive support plate 82, thereby electrically connecting the conductive member to the conductive support plate 82 and the conductive wall plate.

[0300] Furthermore, since the mounting portion is slidably mounted on the rail, in order to ensure smooth sliding of the mounting portion, in the present embodiment, the abutment may be configured as a ball or ball bearing. The ball or ball bearing is configured as part of the conductive member and is electrically connected to the conductive member. This configuration reduces the friction between the abutment and the conductive support plate or conductive wall plate, ensuring smooth sliding of the mounting portion and ink cartridge 10 on the ground rail.

[0301] In another embodiment, the conductive member includes not only the second conductive piece, but also a second conductive transmission medium electrically connected to the second conductive piece, and a mounting member electrically connected to the second conductive transmission medium. That is, in this embodiment, the conductive member is composed of the conductive piece, the conductive transmission medium, and the mounting member.

[0302] Furthermore, the mounting member is disposed near the chip, i.e., the mounting member is located at one end of the ink cartridge body away from the rail. One end of the mounting member is connected to the ground terminal of the chip, and the other end of the mounting member extends to the ink chamber of the ink cartridge body and is electrically connected to the printing liquid medium in the ink chamber. For example, if the printing liquid medium is ink, and the ink is connected to the mounting member as a conductive medium, the ground signal of the ground terminal is transmitted to the ink via the mounting member.

[0303] Furthermore, one end of the second conductive piece extends into the ink chamber to contact the ink, and the other end forms a bridge connection. The second conductive piece is straddled above the barrier plate 85 by the bridge connection. The bridge connection can be electrically connected to the conductive support plate, so that a ground signal is transmitted from the ink to the conductive support plate via the second conductive piece.

[0304] 71, the connecting member 140 is configured as the second conductive piece and is configured as a part of the conductive member. The connecting member 140 may be made of a conductive material having a certain hardness, and may be an integrally molded sheet metal member, or may have a structure in which multiple parts are connected together. The embodiment of the present application is not limited to this.

[0305] The connecting member 140 further includes a fixing member 141. The fixing member 141 may be made of a silicone material. A through-hole is provided in the center of the fixing member 141, allowing the curved portion 1402 of the connecting member 140 to pass through. The method of attaching the connecting member 140 is as follows: First, the fixing member 141 is inserted into the connecting member 140, then the vertical portion 1401 of the connecting member 140 with the fixing member 141 inserted is passed through the through-hole in the upper part of the rear wall 50b of the ink cartridge 10, and then the position of the fixing member 141 is adjusted to close the through-hole and bring the connecting member 140 into a predetermined position and posture relative to the ink cartridge 10.

[0306] As shown in FIG. 73, when the connection member 140 is fully attached, the vertical portion 1401 of the connection member 140 is in close contact with the inside of the rear wall 50b of the ink cartridge 10, extends from the end of the bottom of the rear wall 50b closest to the ink outlet 41 along the +Z axis to the top of the rear wall 50b, and is fixed to the ink cartridge 10 by the fixing member 141. The fixing member 141 not only seals the rear wall 50b to prevent ink leakage, but also fixes the connection member 140. The curved portion 1402 of the connection member 140 extends from the through-hole in the fixing member 141 to the outside of the ink cartridge 10, is bent away from the surface of the ink cartridge 10, and is connected to a metal member of the printer. This metal member is the conductive support plate 82 described above.

[0307] As shown in Figures 72 and 75, the conductive member 140a is configured as the mounting member, is made entirely of conductive silicone rubber, and is embedded in the mounting surface of the ink cartridge 10, enabling it to seal the ink cartridge 10 and make contact with the ink. Specifically, the conductive member 140a is located behind the chip 20, and the memory 100 is provided on the rear surface 120b of the chip 20. An opening 111 is provided in the conductive member 140a. The opening 111 is provided to fit the memory 100 and is sized to fit the memory 100.

[0308] In the attached state, the chip 20 is in close contact with at least a portion of the conductive member 140a on the side corresponding to the rear surface 120b. Each of the seventh terminals 137a and 137b (ground terminals in the present application) abuts against the conductive member 140a, and the first surface 140b of the conductive member 140a is used to connect with the chip 20, while the second surface 140c (the surface facing the internal storage chamber of the ink cartridge 10) contacts and is electrically connected to the ink.

[0309] 76 and 77, the connecting member 140 is located in the -X-axis direction of the ink cartridge 10, and the conductive member 140a is located in the +X-axis direction of the ink cartridge 10. Because the ink in the ink cartridge 10 is conductive, in this embodiment, a ground signal between the chip 20 and the printer can be transmitted by the conductive member 140a, the ink, the connecting member 140, and the conductive support plate 82.

[0310] Of course, the grounding method of the ink cartridge according to this embodiment can also be applied to other types of chips. For example, if chip 20 has four terminals on the front side and a ground terminal (not shown) on the back side, the ground terminal can similarly transmit a ground signal between the chip and the printer via conductive member 140a, ink, connecting member 140, and conductive support plate 82 (member 1401 is inside the ink cartridge and is electrically connected to the ink).

[0311] According to the above invention, the ground signal is transmitted to the chip 20 by the conductive support plate 82, the connecting member 140, the ink, and the conductive member 140a, improving stability and reducing situations where the ground is not available or the ground becomes unstable. When the ink in the ink cartridge 10 is used up or is about to be used up, the ground signal on the chip 20 cannot be transmitted to the printer, and the printer displays a message that the ink cartridge is not installed. This serves the same function as the printer's own message that the ink is out of ink, reminding the user to replace the ink cartridge.

[0312] Fifth embodiment Before describing the embodiments of the present invention, the coordinate system of the drawings will be described. 3 The Y-axis indicates the second direction. The second direction is defined as the direction of reciprocating sliding of the mounting part. The Z-axis indicates the first direction. 1 Indicates the direction of the 1 The direction is defined as the direction in which the ink cartridge assembly is inserted into the mounting portion. 3 The direction of the second direction and 1 The direction of is defined as the normal direction of the plane.

[0313] 78 and 79, based on the first embodiment, the printing device according to the present embodiment further includes a conductive unit 300 and a mounting unit 90. The conductive unit 300 is configured as a grounding member of the printing device. For example, the conductive unit 300 may be the ground rail or the conductive support plate, or may even be another metal member that transmits a ground signal; the present embodiment is not limited thereto.

[0314] In the embodiment of the present application, the conductive unit 300 is provided outside the mounting portion 90, and the conductive unit 300 can be used to transmit a ground signal. The length extension direction of the conductive unit 300 coincides with the second direction. In the printing device, a track (not shown) is provided near the conductive unit 300, and the mounting portion 90 is slidably attached on the track. During operation of the printing device, the mounting portion 90 can slide along the track, and the extension direction of the track coincides with the extension direction of the conductive unit 300. That is, the mounting portion 90 can slide linearly relative to the conductive unit 300 along the second direction.

[0315] The printing device according to the embodiment of the present application further includes an ink cartridge assembly, which is removably mounted in the printing device. The mounting portion 90 includes a case and a contact pin assembly 91 provided in the case. The case is provided with a storage chamber 995 into which the ink cartridge assembly is inserted, and the contact pin assembly 91 is provided in the storage chamber 995.

[0316] A portion of the contact pin assembly 91 is located within the storage chamber 995 and is used to electrically connect with the ink cartridge assembly. Another portion of the contact pin assembly 91 is connected to a printed circuit of the printing device, so that when the ink cartridge assembly is inserted into the case, communication can be established with the printing device via the contact pin assembly 91.

[0317] In order to transmit the ground signal of the conductive unit 300 to the ink cartridge assembly, the ink cartridge assembly according to the embodiment of the present application further includes a connection assembly. The connection assembly is configured as a conductive member. The ink cartridge assembly receives the ground signal transmitted from the conductive unit 300 via the conductive member.

[0318] Specifically, the ink cartridge assembly includes at least one ink cartridge 10, and each ink cartridge 10 can be inserted into the storage chamber 995 and electrically connected to a corresponding contact pin assembly 91. The number of contact pin assemblies 91 corresponds to the number of ink cartridges 10.

[0319] 80 and 81, each ink cartridge 10 includes a case 50 and a chip 20 provided in the case 50. The chip 20 includes a substrate 21, a plurality of contacts provided on the substrate 21, and a memory element 24 (the memory element 24 is provided on the back surface of the substrate 21 and can be arranged with reference to FIG. 95). Each of the plurality of contacts is electrically connected to the memory element 24.

[0320] Illustratively, the plurality of contacts includes one ground contact 23, which is used for transmitting a ground signal. The ground contact 23 is configured to contact the connection assembly (to be in electrical contact with the conductive member). That is, the ground contact 23 does not contact any contact pins. Furthermore, the other contacts 22 are configured as one or more of a memory element contact, a high-voltage contact, and a detection contact (for example, for detecting a short circuit between contacts or detecting the installation of an ink cartridge), and the other contacts 22 contact and are electrically connected to each contact pin of the corresponding contact pin assembly 91.

[0321] In the embodiment of the present application, the memory element contact and / or the detection contact are electrically connected to the memory element 24, and the memory element 24 stores a communication and data processing program, remaining ink amount information in the ink cartridge, and / or product information related to the ink cartridge. Alternatively, a high-voltage device is provided in the ink cartridge chip 20, and the high-voltage contact is electrically connected to the high-voltage device and used to detect a short circuit between the contacts. Alternatively, a detection device is provided in the ink cartridge chip 20, and the detection contact is electrically connected to the detection device and used to detect a short circuit between the contacts or to detect whether the ink cartridge is installed.

[0322] In an embodiment of the present application, the ground contact 23 and the memory element 24 are located on different surfaces of the substrate 21, while the ground contact 23 and the other contacts 22 are located on the same surface of the substrate 21. For example, the ground contact 23 and the other contacts 22 are located on a first surface of the substrate 21, the other contacts 22 have a first projection onto the first surface of the substrate 21, a first region is formed surrounded by the first projections of the multiple other contacts 22, the ground contact has a second projection onto the first surface, and the second projection is located outside the first region. In the second direction (Y-axis direction), there is an overlapping portion between the second projection and the first region.

[0323] Furthermore, in the case where the ground contact 23 and the other contacts 22 are located on the same surface of the substrate 21, in this embodiment, a gap 25 can be provided between the ground contact 23 and the other contacts 22. With this configuration, if ink or other foreign matter adheres to the chip 20 during use, the foreign matter is contained within the gap 25, thereby preventing the foreign matter from adhering to the chip 20 and causing a short circuit between the ground contact 23 and the other contacts 22.

[0324] 79, the connection assembly includes a first connection member 61 and a second connection member 62 to be connected, and each of the first connection member 61 and the second connection member 62 can transmit a ground signal. The first connection member 61 is used to connect the conductive unit 300 and the second connection member 62, and a portion of the first connection member 61 connects with the conductive unit 300 to form an outer contact point of the chip. For example, the portion of the first connection member 61 is fixedly connected to the surface of the conductive unit 300 and is configured not to move relative to the conductive unit 300.

[0325] A portion of the first connecting member 61 is arranged so that it can be dynamically displaced in synchronization with the reciprocating movement of the mounting portion 90. That is, the portion of the first connecting member 61 forms an outer contact point with the conductive unit 300, and can prevent sliding friction between the outer contact point and the surface of the conductive unit 300.

[0326] The second connecting member 62 is provided in the mounting portion 90 and does not move relative to the mounting portion 90. For example, the second connecting member 62 is provided in the receiving chamber 995 and fixed to the case of the mounting portion 90. One end of the second connecting member 62 is electrically connected to the ground contact 23 of the chip 20, and the other end of the second connecting member 62 is connected to the first connecting member 61. As a result, the ground signal of the conductive unit 300 is transmitted to the ground contact 23 of the chip 20 via the first connecting member 61 and the second connecting member 62.

[0327] In the related art, the external conductor is directly electrically connected to the conductive unit, and slides on the surface of the conductive unit following the movement of the mounting part in the direction of movement of the mounting part. Compared to the related art, in the embodiment of the present application, a portion of the first connecting member 61 dynamically displaces synchronously following the reciprocating movement of the mounting part 90. As a result, the outer contact formed by the other portion of the first connecting member 61 being fixedly connected to the conductive unit 300 does not generate sliding friction with the conductive unit 300, and it is possible to avoid large noise that affects the user experience when the outer contact slides back and forth along the surface of the conductive unit 300.

[0328] Furthermore, a portion of the first connecting member 61 can be dynamically displaced in synchronization with the reciprocating movement of the mounting portion 90, making it possible to prevent the outer contacts (the outer contacts being the connecting portions of the first connecting member 61 with the conductive unit 300) from coming off the surface of the conductive unit 300 due to vibration or other causes. Also, it is possible to prevent the outer contacts from being deformed due to sliding friction with the conductive unit 300 over a long period of time, thereby improving the stability of the grounding of the chip 20.

[0329] 82, in order to facilitate positioning and supporting of the second connection member 62 when the second connection member 62 is attached in the storage chamber 995, the mounting portion 90 according to the embodiment of the present application further includes a first support portion 991. 1Along this direction, the first support portion 991 is provided above the contact pin assembly 91. For example, the first support portion 991 may be a partial support plane formed on the upper part of the case. 3 Along this direction, the support plane is located on one side of each contact pin assembly 91. 1 Along the direction of the arrows, the support plane is located above each contact pin assembly 91.

[0330] 79 and 80, in an embodiment, the second connecting member 62 is inserted into the receiving chamber 995, and a portion of the second connecting member 62 abuts against the first support portion 991. 1 9. In addition, when the ink cartridge assembly is inserted into the storage chamber 995, the portion of the second connecting member 62 extending to the contact pin assembly 91 comes into contact with the ground contact 23 of the chip 20 and is electrically connected to it.

[0331] 83 and 84, in this embodiment, the second connecting member 62 includes a main body 621 and at least one extending portion 622. The main body 621 can abut against the first support portion 991 so that the second connecting member 62 can be inserted into the case. The lengthwise extension direction of the main body 621 is the same as the lengthwise extension direction of the first support portion 991, and both extend along the second direction. The main body 621 can be in close contact with the supporting surface of the first support portion 991.

[0332] The second connection member 62 includes a plurality of extensions 622, and the number of extensions 622 matches the number of contact pin assemblies 91 (or the number of chips 20). That is, each extension 622 corresponds to one chip 20. The plurality of extensions 622 are arranged on the main body 621 at intervals along the second direction.

[0333] Each extension 622 is tooth-shaped, and one end of the extension 622 is connected to the main body 621, and the other end of the extension 622 is connected to the first 1The extending portion 622 is configured to extend along the direction of the arrow A. The extending portion 622 can also extend to the outside of the contact pin assembly 91. The extending portion 622 has an electrical contact portion 6221 on one side facing the chip 20. The electrical contact portion 6221 is electrically connected to the ground contact 23 of the chip 20.

[0334] Furthermore, the main body 621 is provided with a first positioning portion 6211, 3 The extending portion 622 and the first positioning portion 6211 are arranged on the main body 621 with a gap therebetween along this direction. 1 The first positioning portion 6211 may be provided on the upper part of the second connecting member 62 along this direction.

[0335] For example, the first positioning part 6211 is a horizontal plate, one end of which is connected to the main body 621, and the other end of which is connected to the first positioning part 6211. 3 The horizontal plate has a horizontal surface that engages with the first support portion 991, and when the second connecting member 62 is inserted into the mounting portion 90, the first positioning portion 6211 comes into close contact with the support surface of the first support portion 991, and at least the first 1 The position of the second connecting member 62 can be limited in the direction.

[0336] Based on the above embodiment, the main body 621 is further provided with a second positioning portion 6212, and the main body 621 has an inclined surface, and a plurality of positioning grooves are provided on the inclined surface, and each positioning groove is configured as the second positioning portion 6212. 1 The upper portion of the first positioning portion 6211 is provided near the first positioning portion 6211.

[0337] Exemplarily, the positioning groove is configured as a second positioning portion 6212, and the first positioning portion 6211 is located above the upper portion of the positioning groove and is arranged in the extending direction of the positioning groove. An opening is provided at the bottom of the positioning groove, and the opening is located at the bottom of the inclined surface and is provided near the upper portion of the extending portion 622. For example, the opening of the positioning groove may be located between two adjacent extending portions 622.

[0338] 82, the mounting portion 90 is provided with a spacing member 992 that fits into the positioning groove. That is, a plurality of spacing members 992 are arranged at intervals in the second direction in the storage chamber 995, and the spacing members 992 are 1 The spacing members 992 extend along the direction of the arrows 991, and between each pair of adjacent spacing members 992, a space for arranging one contact pin assembly 91 is formed. For example, the spacing members 992 may be partition plates for separating the contact pin assemblies 91.

[0339] No. 1 At least a portion of the spacing member 992 protrudes from the contact pin assembly 91 along the direction of the second support portion 992, forming a second support portion 992a. The second support portion 992a is fitted into the positioning groove, and when the second connection member 62 is inserted into the storage chamber 995, the positioning groove is fitted into the second support portion 992a. In other words, the second positioning portion 6212 is inserted into the second support portion 992a. This allows at least the first 3 The position of the second connecting member 62 can be limited in the first direction and the second direction.

[0340] When the first positioning portion 6211 is in close contact with the first support portion 991, the second positioning portion 6212 is inserted into the second support portion 992a. That is, the second connecting member 62 can be detachably attached to the mounting portion 90 by the cooperation of the first positioning portion 6211 and the second positioning portion 6212. Furthermore, the ground contact 23 of the chip 20 is electrically connected to the conductive unit 300 via the electrical contact portion 6221, the extension portion 622, the main body 621, and the first connecting member 61, thereby realizing grounding of the chip 20.

[0341] Referring to Figure 81, in this example, the first connection member 61 according to the embodiment of the present invention includes a conductive carrier. 3 That is, the length direction of the conductive carrier coincides with the sliding direction of the mounting portion 90.

[0342] The conductive carrier may be a flexible and deformable conductive metal piece. The conductive carrier is disposed between the case and the conductive unit 300, and at least a portion of one end of the conductive carrier is fixed to the conductive unit 300. The other end of the conductive carrier extends above the case and is electrically connected to the main body 621 of the second connection member 62 or a contact portion provided on the main body 621.

[0343] Furthermore, the length of the conductive carrier has a certain margin, which forms a deformable portion 613. This margin is designed to accommodate displacement of the mounting portion 90 at the conductive unit 300, allowing the deformable portion 613 to expand and contract and deform when the conductive carrier slides on the mounting portion 90. That is, the deformable portion 613 can dynamically displace in sync with the reciprocating movement of the mounting portion 90.

[0344] With this configuration, the outer contacts formed by contact between the first connecting member 61 and the conductive unit 300 do not slide or rub against the conductive unit 300. This prevents large noise from being generated when the outer contacts of the chip 20 slide back and forth along the surface of the conductive unit 300. This also prevents the outer contacts of the chip 20 from deforming due to frictional movement against the conductive unit 300 over a long period of time, thereby improving the stability of the grounding of the chip 20. Furthermore, since a portion of the first connecting member 61 connects to the conductive unit 300, it is possible to prevent the outer contacts from detaching from the surface of the conductive unit 300 and improve the stability of the grounding of the chip 20.

[0345] Based on the above embodiment, the conductive carrier according to the embodiment of the present application includes a conductive portion and an insulating portion. The insulating portion covers a portion of the conductive portion, and the portions of the conductive portion exposed from both ends of the insulating portion are respectively configured as a first contact portion 611 and a second contact portion 612. Here, the first contact portion 611 is fixedly connected to the conductive unit 300, and the second contact portion 612 is electrically connected to the second connecting member 62.

[0346] Illustratively, the conductive portion is configured as a conductive core or conductive piece, and the insulating portion is configured as an insulating layer covering the conductive core. For example, the conductive core includes a first end and a second end arranged opposite each other, and the insulating layer includes a middle portion of the conductive core. Since the first end and the second end of the conductive core are exposed from the insulating layer, the first end of the conductive core is configured as a first contact portion 611, and the second end of the conductive core is configured as a second contact portion 612. Here, the first contact portion 611 is connected to a side surface of the conductive unit 300, and the second contact portion 612 is electrically connected to the second connecting member 62.

[0347] In order to improve the connection reliability between the second contact portion 612 and the second connection member 62, the second connection member 62 is provided with a third contact portion 623. The third contact portion 623 is located on the main body 621 of the second connection member 62, and is provided in the vicinity of the second contact portion 612. For example, the third contact portion 623 may be a conductive protrusion (conductive terminal) provided on the main body 621. The second contact portion 612 can be in close contact with the conductive protrusion and electrically connected to it.

[0348] Furthermore, the second connection member 62 is entirely or at least partially made of a conductive material, which allows the ground contact of the chip 20 to be electrically connected to the conductive unit 300 via the first connection member 61 and the second connection member 62. For example, if safety in use is ensured, the surfaces of the second connection member 62, excluding the third contact portion 623 and the electrical contact portion 6221 provided on the extension portion 622, may be coated with an insulating material or provided with an insulating layer. This prevents the second connection member 62 from contacting other electrical components, improving the reliability of ground signal transmission.

[0349] The printing device according to the embodiment of the present invention further includes a communication member 200, at least a portion of which is deformable. For example, the communication member 200 may be a flat cable or a ribbon cable. One end of the communication member 200 is connected to the mounting portion 90, and the other end is connected to the conductive unit 300. The central portion of the communication member 200 is deformable. A relay board is provided within the mounting portion 90. The relay board communicates with a control unit within the conductive unit 300 via the communication member 200.

[0350] Furthermore, the deformable portion 613 of the first connecting member 61 may be provided on the main body 621 of the communicating member 200. That is, the deformable portion 613 of the conductive carrier is attached to the communicating member 200. With this configuration, the position of the first connecting member 61 can be appropriately limited within the printing device, preventing the first connecting member 61 from interfering with or becoming entangled with other internal members, and as a result, preventing damage to the first connecting member 61.

[0351] 85 and 86, in another example according to an embodiment of the present invention, a first connecting member 61 is provided on a second connecting member 62. The first connecting member 61 is configured as a contact member that is capable of relative movement with respect to the second connecting member 62, and the first connecting member 61 is capable of displacement along the surface of the conductive unit 300.

[0352] As shown in FIG. 87, the second connecting member 62 in this embodiment includes a third positioning portion 624 and a fourth positioning portion 625, and the third positioning portion 624 and the fourth positioning portion 625 may be an integral structure. The third positioning portion 624 is located above the fourth positioning portion 625. The third positioning portion 624 is positioned in the second direction and 3 The third positioning portion 624 extends horizontally along the direction of the mounting portion 90. The third positioning portion 624 can be disposed parallel to the conductive unit 300. When the second connection member 62 is attached in the mounting portion 90, the third positioning portion 624 can abut against the upper surface of the mounting portion 90.

[0353] 82, the mounting portion 90 is provided with a third support portion 993 that engages with the third positioning portion 624. The third support portion 993 may be a part of the upper surface of the case. In the embodiment of the present invention, the third support portion 993 is a part of the upper surface on the side closer to the conductive unit 300. The third support portion 993 is 3 along the direction of the ink cartridge assembly 991, and 1 The third support portion 993 is disposed so as to protrude further in the direction than the first support portion 991. That is, the height of the third support portion 993 is greater than that of the first support portion 991.

[0354] The fourth positioning portion 625 is disposed below the third positioning portion 624 at an incline. 1Along the direction, one side of the fourth positioning portion 625 is connected to the bottom of the third positioning portion 624. The connection position is located on the side of the third positioning portion 624 facing the ink cartridge assembly. 3 That is, the fourth positioning portion 625 may be a positioning slope provided on the second connecting member 62.

[0355] Correspondingly, the mounting portion 90 is provided with a fourth support portion 994 that engages with the fourth positioning portion 625. 3 The fourth support portion 994 is located between the first support portion 991 and the third support portion 993 along the direction of the arrow A. The fourth support portion 994 may be a support slope formed on the upper surface of the case. This support slope engages with the positioning slope.

[0356] When the second connecting member 62 is inserted into the storage chamber 995 of the case, the third positioning portion 624 is in close contact with the third support portion 993. 1 In addition, since the fourth positioning portion 625 is in close contact with the fourth support portion 994, at least the 3 The position of the second connecting member 62 can be limited in the direction.

[0357] Furthermore, in this embodiment, the second connecting member 62 has a first support portion 991 abutting against the first support portion 991. 3 The electrical connection 626 is further included. 3 The electrical connection portion 626 is located on the side of the fourth positioning portion 625 that is away from the third positioning portion 624. 3 One side of the electrical connection portion 626 is connected to the fourth positioning portion 625, and the 3 The electrical connection 626 is 3 The ink cartridge assembly 10 extends horizontally along the direction of the arrows.

[0358] For example, 3The electrical connection portion 626 may be provided in parallel with the third positioning portion 624. 3 along the direction of the third positioning portion 624 and 3 The electrical connection portions 626 are respectively arranged parallel to both sides of the fourth positioning portion 625, and the three form a stepped structure or a Z-shaped structure.

[0359] In addition, 3 The electrical connection portion 626 is made entirely or at least partially of a conductive material. 3 The electrical connection portion 626 is used to electrically connect to the ground contact 23. Thus, the ground signal in the conductive unit 300 is transmitted through the first connecting member 61, the third positioning portion 624, the fourth positioning portion 625, and the 3 626 to the ground contact 23 of the chip 20.

[0360] Based on the above embodiment, the second connecting member 62 according to the embodiment of the present application further includes a receiving portion 627. 1 The housing portion 627 is provided above the third positioning portion 624 in the direction of arrow A. A mounting shaft 629 is provided in the housing portion 627, and the first connecting member 61 is disposed on the mounting shaft 629. The mounting shaft 629 is made of a conductive material.

[0361] Furthermore, at least a portion of the first connection member 61 includes an electrical contact portion for electrically connecting with the conductive unit 300 while rotating. As a result, the ground signal in the conductive unit 300 is transmitted through the first connection member 61, the mounting shaft 629, the third positioning portion 624, the fourth positioning portion 625, and the 3 626 to the ground contact 23 of the chip 20.

[0362] Specifically, the storage section 627 is provided above and parallel to the third positioning section 624. 3In this direction, the projections of the receiving portion 627 and the conductive unit 300 at least partially overlap. This ensures that the first connecting member 61 provided in the receiving portion 627 comes into contact with the conductive unit 300.

[0363] The accommodation portion 627 has an accommodation groove, which is formed in an elongated shape. Furthermore, the longitudinal extension direction of the accommodation groove coincides with the extension direction of the conductive unit 300, and the opening of the accommodation groove is provided facing the conductive unit 300. A mounting shaft 629 is provided in the accommodation groove, and the axial direction of the mounting shaft 629 is 1 The first connecting member 61 is attached to the mounting shaft 629 and is rotatable relative to the mounting shaft 629.

[0364] At least a portion of the first connection member 61 has an electric contact portion, and the electric contact portion is electrically connected to the conductive unit 300 while rotating. For example, the first connection member 61 is configured as a conductive roller, which is rotatably connected to the mounting shaft 629, and the outer circumferential surface of the conductive roller can contact the conductive unit 300. That is, as the mounting portion 90 moves relative to the conductive unit 300, the conductive roller continuously rotates, thereby bringing the outer circumferential surface at different positions into contact with the conductive unit 300. That is, a portion of the first connection member 61 can dynamically displace in sync with the reciprocating movement posture of the mounting portion 90 (the conductive roller continuously rotates).

[0365] With this configuration, the outer contacts formed by contact between the first connecting member 61 and the conductive unit 300 do not undergo relative displacement or sliding friction in the extension direction of the conductive unit 300. As a result, it is possible to avoid the generation of large noise when the outer contacts of the chip 20 slide back and forth along the surface of the conductive unit 300. It is also possible to prevent the outer contacts of the chip 20 from deforming due to heat caused by friction with the conductive unit 300 over a long period of time. This improves the grounding stability of the chip 20. Furthermore, since a portion of the first connecting member 61 contacts the conductive unit 300 while rotating, detachment of the outer contacts from the surface of the conductive unit 300 due to wear is effectively reduced, improving the grounding stability of the chip 20.

[0366] 88 to 90, based on the above embodiment, the connection assembly according to the embodiment of the present application further includes an auxiliary connection member 63. The auxiliary connection member 63 is connected to the ground contact 23 and the 3 The second connecting member 62 is used to electrically connect to the electrical connection portion 626. With this configuration, the applicability of the second connecting member 62 and the reliability of the electrical connection can be improved.

[0367] Specifically, the auxiliary connecting member 63 can be configured as a conductive wire or a conductive piece. The tip 20 is disposed below the handle 11 of the ink cartridge, and the two are connected to each other. 1 Furthermore, the chip 20 maintains a constant distance in the direction of the 3 The electrical connection 626 is located below the first 3 The electrical connection portion 626 is provided facing the handle 11 so as to partially overlap it.

[0368] For example, in one embodiment, the auxiliary connecting member 63 is configured as a conductive piece. 3 20 and the ground contact 23 of the chip 20. 3 The conductive piece is used to electrically connect with the electrical connection portion 626 of the first 1The conductive strip extends along the direction of the arrow A, and a first end of the conductive strip is connected to the ground contact 23 of the chip 20, and a second end of the conductive strip is connected to the ground contact 23 of the chip 20. 1 The second end of the conductive piece extends to the handle 11, and the first end of the conductive piece extends upward along the direction of the handle 11. 3 626 of the casing 622.

[0369] A fourth contact portion 631 is provided at the second end of the conductive piece, thereby forming a contact portion. The fourth contact portion 631 may be a conductive terminal disposed on the conductive piece. The conductive terminal may be a first 3 The fourth contact portion 631 is electrically connected to the first electrical connection portion 626 of the handle 11. 1 Illustratively, the first and second directions overlap. 1 If the plane formed by the direction of is defined as the first projection plane, then the 3 When observed along this direction, the projection of the fourth contact portion 631 onto the first projection plane and the projection of the handle 11 onto the first projection plane partially overlap.

[0370] As shown in Figures 91 to 95, in another embodiment, the auxiliary connecting member 63 is configured as a conductive plate. The conductive plate can be formed integrally with the substrate 21 of the chip 20. That is, the conductive plate is considered to be a part of the substrate 21. 1 A portion of the substrate 21 can be extended along the direction of the auxiliary connecting member 63 .

[0371] No. 1 In this direction, the upper end of the conductive plate is located below the handle 11, and 3 The ground contact 23 and the fourth contact portion 631 may be provided on the upper end of the conductive plate and may be arranged on both sides of the conductive plate. The fourth contact portion 631 is located below the handle 11 and is arranged close to the handle 11. The ground contact 23 and the fourth contact portion 631 may be electrically connected via a conductive pattern or a through hole.

[0372] No. 3In order to electrically connect the electrical connection portion 626 to the ground contact 23 to realize transmission of a ground signal, the second connection member 62 according to this embodiment further includes a second electrical connection portion 628. The second electrical connection portion 628 has an escape space for the handle 11, and a portion of the second electrical connection portion 628 is 3 The other part is disposed below the handle 11 and is electrically connected to the fourth contact part 631. The fourth contact part 631 is disposed below the handle 11, and the two do not overlap. 3 When observed along the direction of the arrows, the projection of the fourth contact portion 631 onto the first projection plane and the projection of the handle 11 onto the first projection plane do not overlap.

[0373] For example, the second electrical connection portion 628 is L-shaped and includes a first horizontal portion and a first vertical portion. The first horizontal portion is disposed below the handle 11 and extends along the second direction. The first vertical portion is 1 The first vertical portion extends along the direction of the handle 11 and is disposed on one side of the handle 11 so as to avoid the handle 11. 3 626 of the casing.

[0374] The entire or at least a portion of the auxiliary connecting member 63 is made of a conductive material, and the ground contact 23 of the chip 20 is electrically connected to the conductive unit 300 via the first connecting member 61, the second connecting member 62, and the auxiliary connecting member 63. For example, to ensure safety in use, the auxiliary connecting member 63 in this embodiment, except for the fourth contact portion 631, is coated with an insulating material or insulating layer. This prevents the auxiliary connecting member 63 from contacting other electrical components and improves the reliability of ground signal transmission.

[0375] In the embodiment of the present application, the ground contact 23 may be arranged on the same surface of the substrate 21 as the memory element 24, and the other contacts 22 may be arranged on a different surface of the substrate 21 from the ground contact 23. The ground contact 23 and the other contacts 22 may each be electrically connected to the memory element 24 via a conductive pattern.

[0376] For example, the substrate 21 has a first surface and a second surface facing each other, and each of the other contacts 22 is disposed on the first surface of the substrate 21. The ground contacts 23 are disposed on the second surface of the substrate 21. The other contacts 22 have a first projection onto the first surface of the substrate 21, and a first region is formed by being surrounded by the first projections of the multiple other contacts 22. The ground contacts 23 have a second projection onto the second surface, and the second projection is located outside the first region. In the second direction (Y-axis direction), there is an overlapping portion between the second projection and the first region.
