The remaining terminals (first terminal 131, third terminal 133, second terminal 132, fifth terminal 135) are electrically connected to the second surface portions of the corresponding first portions 911a, 913a, 912a, 915a of the remaining contact pins (first contact pin 911, third contact pin 913, second contact pin 912, fifth contact pin 915), respectively. Specifically, in the ink cartridge 10 on which the chip 100 of the present embodiment is mounted, during the mounting of the mounting portion 90, the restricting surface 603a guides the first portion 914a of the fourth contact pin 914 into the +y-axis side of the restricting portion 603 (also referred to as a contact pin guiding portion), so that the restricting portion 603 contacts the fourth surface portion of the first portion 914a of the fourth contact pin 914 and presses the fourth contact pin 914 in the +y-axis direction, deflecting/deforming the first portion 914a of the fourth contact pin 914 in the +y-axis direction, and electrically connecting the second surface portion of the first portion 914a of the fourth contact pin 914 with the fourth terminal 134, so that the distance d1 between the contact portion C2 of the second terminal 132 (clock terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) in the Y-axis direction in the mounted state is larger than the distance d2 between the second contact pin 912 and the fourth contact pin 914 in the Y-axis direction in the natural state.

2. The ground terminal and the clock terminal are auxiliary contact terminals, and the contact pin guide parts guide the corresponding contact pin parts to deflect towards the-Y axis direction and contact the ground terminal and the clock terminal. The remaining terminals (first terminal 131, third terminal 133, fourth terminal 134) are electrically connected to the second surface portions of the corresponding first portions 911a, 913a, 914a of the remaining contact pins (first contact pin 911, third contact pin 913, fourth contact pin 914), respectively. Specifically, in the ink cartridge 10 on which the chip 100 of the present embodiment is mounted, during the mounting of the mounting portion 90, the second left side surface 1202c (contact pin guide portion) guides the first portion 915a of the fifth contact pin 915 into the second recess 125, so that the second left side surface 1202c (contact pin guide portion) contacts the third surface portion of the first portion 915a of the fifth contact pin 915 and presses the fifth contact pin 915 in the-Y direction, thereby deflecting/deforming the first portion 915a of the fifth contact pin 915 in the-Y direction, and the first surface portion of the first portion 915a of the fifth contact pin 915 is electrically connected to the fifth terminal 135; the first left side surface 1201c (contact pin guide portion) guides the first portion 912a of the second contact pin 912 into the first recess 124, so that the first left side surface 1201c contacts the third surface portion of the first portion 912a of the second contact pin 912 and presses the second contact pin 912 in the-Y axis direction, deflecting/deforming the first portion 912a of the second contact pin 912 in the-Y axis direction, and the first surface portion of the first portion 912a of the second contact pin 912 is electrically connected to the second terminal 132. So that the distance d1 in the Y-axis direction of the contact portion C3 of the third terminal 133 (power terminal) and the contact portion C5 of the fifth terminal 135 (ground terminal) in the mounted state is smaller than the distance d2 in the Y-axis direction of the third contact pin 913 and the fifth contact pin 915 in the natural state. The advantage of this design is that it enables a compact arrangement of terminals, which is advantageous for achieving miniaturization of the chip 100. The distance d1 in the Y-axis direction between the contact portion C2 of the second terminal 132 (clock terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) in the state where the chip 100/ink cartridge 10 is mounted to the mounting portion is larger than the distance d2 in the Y-axis direction between the second contact pin 912 and the fourth contact pin 914 in the natural state. The distance between the contact portion C4 of the fourth terminal 134 (reset terminal) and the contact portion C5 of the fifth terminal 135 (ground terminal) in the extending direction of the second reference line is smaller than the distance between the fourth contact pin 914 and the fifth contact pin 915 in the extending direction of the second reference line in the natural state in the state in which the chip 100/ink cartridge 10 is mounted to the mounting portion; the distance between the contact portion C3 of the third terminal 133 (power supply terminal) and the contact portion C2 of the second terminal 132 (clock terminal) in the extending direction of the second reference line is larger than the distance between the third contact pin 913 and the second contact pin 912 in the extending direction of the second reference line in the natural state when the chip 100/ink cartridge 10 is mounted to the mounting portion 90.

Specifically, in the ink cartridge 10 on which the chip 100 of the present embodiment is mounted, during the process of mounting the chip 100 on the mounting portion 90, the restricting surface 603a guides the first portion 914a of the fourth contact pin 911 into the +y-axis side of the restricting portion 603 (also referred to as a contact pin guiding portion), so that the restricting portion 603 contacts the fourth surface portion of the first portion 914a of the fourth contact pin 914 and presses the fourth contact pin 914 in the +y-axis direction, thereby deflecting/deforming the first portion 914a of the fourth contact pin 914 in the +y-axis direction, and electrically connecting the second surface portion of the first portion 914a of the fourth contact pin 914 with the fourth terminal 134; the second left side 1202c (contact pin guide) will guide the first portion 915a of the fifth contact pin 915 into the second recess 125, such that the second left side 1202c (contact pin guide) contacts the third surface portion of the first portion 915a of the fifth contact pin 915 and presses the fifth contact pin 915 in the-Y direction, deflecting/deforming the first portion 915a of the fifth contact pin 915 in the-Y direction, the first surface portion of the first portion 915a of the fifth contact pin 915 making electrical connection with the fifth terminal 135; the first left side surface 1201c (contact pin guide portion) guides the first portion 912a of the second contact pin 912 into the first recess 124, so that the first left side surface 1201c contacts the third surface portion of the first portion 912a of the second contact pin 912 and presses the second contact pin 912 in the-Y axis direction, deflecting/deforming the first portion 912a of the second contact pin 912 in the-Y axis direction, and the first surface portion of the first portion 912a of the second contact pin 912 is electrically connected to the second terminal 132. The distance d1 in the Y-axis direction (Y-axis direction) between the contact portion C2 of the second terminal 132 (clock terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) in the state where the chip 100/ink cartridge 10 is mounted to the mounting portion is larger than the distance d2 in the Y-axis direction between the second contact pin 912 and the fourth contact pin 914 in the natural state. The distance between the contact portion C4 of the fourth terminal 134 (reset terminal) and the contact portion C5 of the fifth terminal 135 (ground terminal) in the extending direction of the second reference line L2 is smaller than the distance between the fourth contact pin 914 and the fifth contact pin 915 in the extending direction of the second reference line (Y-axis direction) in a natural state when the chip 100/ink cartridge 10 is mounted to the mounting portion; the distance between the contact portion C3 of the third terminal 133 (power supply terminal) and the contact portion C2 of the second terminal 132 (clock terminal) in the extending direction of the second reference line L2 is larger than the distance between the third contact pin 915 and the second contact pin 912 in the extending direction of the second reference line (Y-axis direction) in a natural state when the chip 100/ink cartridge 10 is mounted to the mounting portion 90; the distance between the contact portion C3 of the third terminal 133 (power terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) in the state where the chip 100/ink cartridge 10 is mounted to the mounting portion 90 is greater than the distance between the third contact pin 913 and the fourth contact pin 914 in the extending direction (Y axis direction) of the second reference line L2 in the natural state.

In the present embodiment, the restricting portion 603 (stylus guide portion) is a protrusion protruding from the substrate 120 in the X-axis direction. The design has the advantages that: when the ink cartridge 10 accidentally drops onto the floor and the front surface 120a of the chip substrate 120 faces the ground, the limiting portion 603 contacts the ground before the chip substrate 120, so as to prevent the chip 100 from being damaged or scratched due to collision. Meanwhile, the limiting part 603 is located between the first terminal 131 and the fourth terminal 134 to separate the first terminal 131 from the fourth terminal 134, when foreign matters or friction fragments are accumulated or adhered to the first terminal 131, the foreign matters are not easy to fall onto the contact part of the fourth terminal 134, so that the foreign matters or friction fragments are adhered to the first terminal 131 and the fourth terminal 134 to cause short circuit, and the use safety of the chip is improved. Note that foreign materials include, but are not limited to, conductive liquids such as ink, and conductive solids such as wires, staple leads, and automatic pencil leads, friction debris, and the like.

The handle 30 is used to fix the ink cartridge 10 to the mounting portion 90, preventing the ink cartridge 10 from being detached from the mounting portion 90. Specifically, in the present embodiment, the hook 31 may be provided on the handle 30, the engagement structure 96 may be provided on the mounting portion 90, and when the ink cartridge 10 is mounted on the mounting portion 90, the stylus portion 91 engages with the engagement structure 96 to fix the ink cartridge 10 in the mounting portion 90 by the handle 30.

The using process comprises the following steps:

In the process of mounting the ink cartridge 10 with the chip 100 mounted thereon to the mounting portion 90 of the printing apparatus, the third surface portion 912a of the first portion 912a of the second stylus 912 first abuts against the guide surface 240 of the second protrusion 220 of the stylus guide 200 in the-Y direction, the ink cartridge 10 is mounted downward in the mounting direction P, and the guide surface 240 of the second protrusion 220 of the stylus guide 200 applies a force in the-Y direction to the third surface portion 911a3 of the first portion 912a of the second stylus 912, so that the first portion 912a of the second stylus 912 is deflected/deformed in the-Y direction.

Further, the second stylus 912 at this time is not substantially specifically moved in the X direction, particularly in the +x direction. Reducing movement of the second contact pin 912 in the X direction is beneficial in ensuring that subsequent first contact pins 911 and second contact pins 912 are better guided along the guide surface 240 of the second protrusion 220 into abutment with the second terminal 132.

When the ink cartridge 10 is completely mounted to the mounting portion 90, the first surface portion of the first portion 912a of the second contact pin 912 deformed in the-Y direction contacts the contact portion C2 of the second terminal 132, so that electrical connection occurs.

The principle of deformation during the mounting of the fifth contact pin 915 is the same as that of the second contact pin 912, and will not be described in detail here.

The principle of deformation during the mounting of the fourth contact pin 914 is the same as that of the second contact pin 912, except that the fourth surface portion of the first portion 914a of the fourth contact pin 914 first abuts against the guide surface 240 in the first protrusion 210+y direction of the contact pin guide 200, and the guide surface 240 of the first protrusion 210 of the contact pin guide 200 applies a force in the +y direction to the fourth surface portion of the first portion 914a of the fourth contact pin 914 as the mounting direction P is downward to the ink cartridge 10, so that the first portion 914a of the fourth contact pin 914 is deflected/deformed in the +y axis, and the first surface of the deformed first portion 914a of the fourth contact pin 914 contacts the contact portion C4 of the fourth terminal 134, thereby making electrical connection.

Illustratively, when the chip 100/ink cartridge 10 is mounted to the mounting portion, the distance d1 in the Y-axis direction of the contact portion C2 of the second terminal 132 (clock terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) is greater than the distance d2 in the Y-axis direction of the second contact pin 912 and the fourth contact pin 914 in a natural state. The distance between the contact portion C4 of the fourth terminal 134 (reset terminal) and the contact portion C5 of the fifth terminal 135 (ground terminal) in the extending direction (Y-axis direction) of the second reference line L2 is smaller than the distance between the fourth contact pin 914 and the fifth contact pin 915 in the extending direction of the second reference line in the natural state when the chip 100/ink cartridge 10 is mounted to the mounting portion; when the chip 100/ink cartridge 10 is mounted to the mounting portion 90, the distance between the contact portion C3 of the third terminal 133 (power supply terminal) and the contact portion C2 of the second terminal 132 (clock terminal) in the extending direction (Y-axis direction) of the second reference line L2 is greater than the distance between the third contact pin 915 and the second contact pin 912 in the extending direction (Y-axis direction) of the second reference line in a natural state; when the chip 100/ink cartridge 10 is mounted on the mounting portion 90, the distance between the contact portion C3 of the third terminal 133 (power supply terminal) and the contact portion C4 of the fourth terminal 134 (reset terminal) in the extending direction (Y-axis direction) of the second reference line L2 is larger than the distance between the third contact pin 913 and the fourth contact pin 914 in the extending direction (Y-axis direction) of the second reference line in a natural state.

Further, the first hole 121 is provided in the substrate 120, so that the fourth contact pin 914 can move in the first hole 121 when the ink cartridge 10 is mounted, and the contact of the front surface 120a of the substrate 120 with the second surface portion of the first portion 914a of the fourth contact pin 914 can be prevented when the ink cartridge 10 is mounted in an initial state, so that the substrate 120 applies a force to the first portion 914a of the fourth contact pin 914 in the +x axis direction, and the first portion 914a of the fourth contact pin 914 is retracted in a direction away from the chip, and is retracted in the slit of the contact pin plate 91 b.

As for the remaining first and third contact pins 911, 913, when the ink cartridge 10 is mounted to the mounting portion 90, the second surfaces of the corresponding first portions 911a, 913a of the first and third contact pins 911, 913 are directly electrically connected to the remaining first and third terminals 131, 133, respectively, and the first and third contact pins 911, 913 are not deformed in the Y direction; however, in order to ensure stable contact between the first contact pin 911 and the third contact pin 913 and between the first terminal 131 and the third terminal 133, the first contact pin 911 and the third contact pin 913 may be brought into contact with the substrate 120, and may be moved or deformed in the +x axis direction.

After the stylus guide 200 is extended out of the substrate 120, the first protrusion 210 is positioned in the second recess portion, the second protrusion 220 is adjacent to the first recess portion 124, and the third protrusion 230 is adjacent to the second recess portion 125, so that the stylus guide 200 can be adjacent to the fourth terminal 134, the second terminal 132, and the fifth terminal 135, and when the ink cartridge 10 is mounted in the printing apparatus, the stylus guide 200 guides the fourth stylus 914, the second stylus 912, and the fifth stylus 915 to deform so as to be in contact with the fourth terminal 134, the second terminal 132, and the fifth terminal 135, respectively, thereby connecting the stylus 91a to the chip 100. Specifically, the first protrusion 210 is located on the-Y axis side of the fourth terminal 134, and the first protrusion 210 contacts the fourth surface portion of the first portion 914a of the fourth contact pin 914 and presses the fourth contact pin 914 in the +y axis direction, so that the first portion 914a of the fourth contact pin 914 deflects/deforms in the +y axis direction, and the second surface portion of the first portion 914a of the fourth contact pin 914 is electrically connected to the fourth terminal 134.
