When the chip 13 is engaged with the electrical connection 224, at least a portion of the main body 2241 is inserted between two inner protrusions 1234, each inner protrusion 1234 is in clearance fit with a corresponding end wall of the main body 2241, and the two inner protrusions 1234 can limit the electrical connection 224 in the width direction, which helps to ensure proper engagement between the chip 13 and the electrical connection 224.

As shown in fig. 1 to 8, in the present embodiment, the mounting process of the ink cartridge 10 includes a translational operation and a pressing operation, and specifically, when the ink cartridge 10 is mounted, the ink cartridge 10 is first inserted into the frame 21 from the insertion port 211 to perform the translational operation in the +y axis direction (translational direction), and the ink cartridge 10 is horizontally moved along the guide path 22a under the guide of the third guide portion 225. After the translation operation is completed, the first groove 122 is engaged with the third guide portion 225, the guide section 1232 is engaged with the first guide portion 226, the restriction section 1233 is engaged with the second guide portion 2244, and the chip 13 is completely docked with the electrical connection portion 224. At this time, the movement of the ink cartridge 10 in the width direction is restricted by the two third guide portions 225 arranged in the width direction. Then, the operation end (i.e., -Y-axis end) of the ink container 11 is pressed downward (i.e., + Z-direction) to perform the pressing operation, and the support member 22 is rotated clockwise in fig. 1 to the connection position centering on the rotation shaft 23 against the urging force of the urging member 25. During the rotation of the ink cartridge 10 and the support member 22, the lead-out portion positioning portion 227 enters the lead-in portion positioning portion 121, the lead-out portion 111 is connected to the liquid lead-in portion 24, and the ink cartridge 10 is mounted.

In some other embodiments, the frame 21 of the mounting portion 20 is further provided with a lock mechanism for maintaining the mounted state of the ink cartridge 10, and the ink cartridge 10 is prevented from being rotated counterclockwise by the biasing member 25 together with the support member 22 to a state before the pressing operation.

Modification example one

As a modification of the above embodiment, the difference from the above embodiment is that: the guide interval 1232 is different in structure.

As shown in fig. 9, in the present modification, in the plumb direction, the upper edge of the second portion 12322b is flush with the upper edge of the rear section 12323, and the lower edge of the second portion 12322b is located below the lower edge of the rear section 12323.

Further, as shown in fig. 9, the upper edge of the first portion 12322a is flush with the upper edge of the second portion 12322b, i.e., the upper edge of the first portion 12322a and the upper edge of the second portion 12322b are in the same plane as the upper edge of the rear section 12323.

The upper edge of the first portion 12322a, the upper edge of the second portion 12322b, and the upper edge of the rear section 12323 can be formed by the edges of the same elongated rib 12324, i.e., the upper edge of the first portion 12322a, the upper edge of the second portion 12322b, and the upper edge of the rear section 12323 are joined together.

During installation of the ink cartridge 10, it is relatively more likely that deflection of the ink cartridge 10 at the rear end (-Y-axis end) of the translational direction will occur, and setting the upper edges of the first portion 12322a and the second portion 12322b flush with the upper edge of the rear section 12323 will also allow the front end (-Y-axis end) of the first guide 226 to enter the front section 12322 in a slightly deflected position of the ink cartridge 10, reducing the difficulty in alignment during the translational operation.

Other structures of the ink cartridge 10 of the present modification are the same as those of the above-described embodiment, and will not be described again here.

Modification II

As another modification of the above embodiment, there is a difference from the above embodiment in that: the guide interval 1232 is different in structure.

As shown in fig. 10, in the present modification, the length of the first portion 12322a in the Y-axis direction is longer than that of the above-described embodiment, and specifically, the two ribs 12324 forming the first portion 12322a are bent, the ribs 12324 have portions extending in the-Y-axis direction, and the portions of the two ribs 12324 extending in the-Y-axis direction are opposed to each other in the plumb direction, and the upper and lower edges of the first portion 12322a are formed, respectively, so that the length of the first portion 12322a in the Y-axis direction is increased.

The first portion 12322a is provided longer, and the deviation correcting distance thereof to the first guide portion 226 is also longer, so that the posture correction to the first guide portion 226 can be completed better.

Other structures of the ink cartridge 10 of the present modification are the same as those of the above-described embodiment, and will not be described again here.

The foregoing are merely some embodiments of the utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
