In the front-back direction, the chip 32 is divided into a first portion 321a located in front of the protrusion 325 and a second portion 321b located behind the protrusion 325, with the position of the protrusion 325 being used as a boundary, and the electrical contact 322 is located in the second portion 321b.
Fig. 3 is a side view of the container and the container receiving chamber in the apparatus as viewed in the left-right direction before the container of the present invention is mounted to the container receiving chamber.
After the chip 32 is mounted, the second portion 321b is located higher than the first portion 321a in the up-down direction, or the second portion 321b is located above the first portion 321a, and in the second portion 321b, at least the electrical contact 322 protrudes to the outside of the housing 1, preferably, the first portion 321a does not exceed the housing 1, and the first portion 321a located in front does not interfere with the inner wall of the ink-jet printer during the mounting of the chip 32 with the ink cartridge 100 toward the ink-jet printer, thereby increasing the mounting speed of the ink cartridge 100; as shown in fig. 3, the ink cartridge 100 further includes a light attenuating portion 102 disposed adjacent to the chip 32 in the front-rear direction, the light attenuating portion 102 being detectable by the inkjet printer during mounting of the ink cartridge 100, and when the light attenuating portion 102 is disposed in front of the chip 32, at least the electrical contact portion 322 is disposed above the light attenuating portion 102 in the up-down direction, and the lowest point of the contact pin 204 and the electrical contact portion 322 intersect at a plane D (shown by a dotted line in fig. 3) perpendicular to the up-down direction.
As shown in fig. 3, when the ink cartridge 100 is mounted in the forward direction, the electrical contact 322 interferes with the contact pin base blocking wall 202b before the electrical contact 322 contacts the contact pin 204, and as the ink cartridge 100 is mounted, the electrical contact 322 together with the second portion 321b is pressed downward by the blocking wall 202b to rotate the chip 32 about the protrusion 325 in the clockwise direction until the electrical contact 322 passes the blocking wall 202b and enters the contact pin cavity 202a, and finally, the chip 32 returns to the position where the second portion 321b is located above the first portion 321a by a holding member described below, and the electrical contact 322 is held in contact with the contact pin 204.

The holding member for holding the chip 32 in the second portion 321b higher than the first portion 321a may be an external member from the chip 32 or a member constituting the chip 32 itself, and each will be described below.
When the holding member is an external component from the chip 32/substrate 321, as shown in fig. 1, the holding member is a weight 326 provided on the substrate 32/first portion 321a, and the moment of the weight 326 to the protrusion 325 is generally greater than the moment of the electrical contact 322 to the protrusion 325, so that the second portion 321b will assume a state higher than the first portion 321a under the action of gravity when the chip 32 is mounted. During the process of the chip 32 passing over the blocking wall 202b, the blocking wall 202b presses the second portion 321b, so that the chip 32 rotates integrally around the protrusion 325 until the second portion 321b reaches the contact pin cavity 202a, and then, the chip 32 returns to the state where the second portion 321b is higher than the first portion 321a again; preferably, the moment of the weight 326 to the protrusion 325 is set to be much larger than the moment of the electrical contact 322 to the protrusion 325, and thus, the electrical contact 322 and the contact pin 204 can be held in close contact.

Further, in order to allow the chip 32 (the second portion 321 b/the electrical contacts 322) to move relative to the housing 1 during the process of removing the cartridge 100, from inside the contact pin chamber 202a easily beyond the blocking wall 202b to outside the contact pin chamber 202a, the chip assembly 32 further comprises an auxiliary member, which may be a component from outside the chip 32 or from the chip 32 itself, as will be described below.
When the auxiliary member is an external component of the chip 32, as shown in fig. 1, the auxiliary member is an elastic body 35 located between the substrate 321 and the casing 1, when the electrical contact portion 322 is electrically contacted with the contact pin 204, the chip 32 may be maintained in a state where the second portion 321b is higher than the first portion 321a by the above-mentioned maintaining component without the aid of the elastic body 35, when the chip 32 moves backward along with the whole ink cartridge and the second portion 321b interferes with the side of the blocking wall 202b facing the contact pin cavity, the chip 32 is turned over or is pressed downward to avoid the blocking wall 202b, and finally, the second portion 321b of the chip 32 passes over the blocking wall 202b, and the ink cartridge 100 is smoothly taken out.
Alternatively, the elastic body 35 may be fixedly mounted on the casing 1, and likewise, the elastic body 35 may be operated only when the chip 32 interferes with the blocking wall 202b during the removal of the ink cartridge 100.
When the auxiliary member is a component of the chip 32, the auxiliary member may be an active connection mechanism disposed on the substrate 321, for example, the first portion 321a and the second portion 321b of the substrate 321 are active connections, and when the second portion 321b interferes with the barrier wall 202b, the second portion 321b moves relative to the first portion 321 a/the housing 1 to avoid the barrier wall 202b.
In some embodiments, the auxiliary member is at least a portion of the base plate 321 made of a flexible circuit board, and when the second portion 321b interferes with the barrier wall 202b, the base plate 321 itself may be deformed such that the second portion 321b passes over the barrier wall 202b.
In the above-described embodiment, the container 100 is mounted forward in the front-rear direction, the second portion 321b is located upstream of the first portion 321a in the mounting direction, and the second portion 321b is higher than the first portion 321a in the up-down direction perpendicular to the mounting direction, or the second portion 321b is farther from the container casing 1/ink outlet assembly 2/ink outlet than the first portion 321a, preferably, the second portion 321a is beyond the container casing, and the first portion 321a is not beyond the container casing; however, in other embodiments, the container 100 is not installed forward in the front-rear direction, but installed downward in the up-down direction, in which case, in the installation direction, the second portion 321b is still located upstream of the first portion 321a, and in the front-rear direction perpendicular to the installation direction, the second portion 321b will be located forward or rearward of the first portion 321a, or the second portion 321b is farther away from the container housing 1/ink outlet assembly 2/ink outlet than the first portion 321a, and preferably, the second portion 321a extends beyond the container housing, and the first portion 321a does not extend beyond the container housing.
