The stopper 323 further includes a support arm 3232 connecting the stopper arm 3231 and the front end portion 32, one end of the support arm 3232 is connected to the upper end face 32b, the other end is connected to one end of the stopper arm 3231 in the-Y axis direction (i.e., connected to the rear section 3231b of the stopper arm 3231), and the stopper arm 3231 extends in the +z axis direction, i.e., the support arm 3232 is perpendicular to the stopper arm 3231.

As shown in fig. 6 to 9, the electrical connection portion 52t includes an upper side portion 52b located above the restricted portion 52a and a lower side portion 52c located below the restricted portion 52a, and the mounting groove 322 has side blocking walls 3241 that mate with the lower side portion 52c at both ends in the width direction, and one end of the lower side portion 52c near the front end portion 32 is located between the two side blocking walls 3241. When the chip 33 is engaged with the electrical connection portion 52t, the lower side portion 52c is inserted between the two side blocking walls 3241, and the lower side portion 52c is in clearance fit with the side blocking walls 3241, and the two side blocking walls 3241 can limit the electrical connection portion 52t in the width direction of the ink cartridge, which helps to ensure proper engagement between the chip 33 and the electrical connection portion 52t.

Further, the spacing between the two side barrier walls 3241 is 14.5mm-19.2mm. This numerical range is established with reference to the distance between the two side wall plates of the lower side portion 52c and the distance between the outer side surfaces of the two restricted portions 52a, and ensures that the front end of the lower side portion 52c can enter the space between the two side blocking walls 3241, and the restricted portions 52a do not enter the space between the two side blocking walls 3241.

As shown in fig. 3 to 6, the upper end surface 32b is provided with a penetration upper end surface 32b, a front end surface 32a, and a relief portion 325 below the stopper arm 3231; the escape portion 325 at least partially overlaps the side blocking wall 3241 in the plumb direction. The electrical connection portion 52t is movably provided on the mounting portion, and there is a small moving space in each direction on the plane defined by the width direction and the plumb direction of the ink cartridge, and strict reset cannot be ensured, so that the introduction avoiding portion 325 in the region where the front end portion 32 is liable to interfere with the restricted portion 52a can accommodate the electrical connection portion 52t having different initial attitudes.

Further, as shown in fig. 4 and 5, the front end 32 further includes a side blocking portion 324 separating the escape portion 325 from the mounting groove 322, the side blocking portion 324 is a plate or sheet, the side blocking portion 324 extends in a plane defined by the Z axis and the Y axis, and the side blocking portion 324 is located below the limiting arm 3231 and has a certain interval from the limiting arm 3231.

The relief portion 325 may penetrate through the upper end surface 32b and the lower end surface 32c of the front end portion 32, and further, a width of an end of at least one relief portion 325 near the lower end surface 32c is larger than a width of an end of the relief portion 325 near the upper end surface 32b, specifically, a width of an end of the relief portion 325 near the lower end surface 32c on the-X axis side of the mounting groove 322 is larger than an end near the upper end surface 32 b. The escape portion 325 can thereby also escape the positioning portion 53 during the process of mounting the ink cartridge.

As shown in fig. 4 and 5, the side stopper 324 includes an inner convex portion 3242 provided on the side stopper wall 3241, the inner convex portion 3242 includes a guide inclined surface 3242a inclined with respect to the mounting direction and an upper abutment surface 3242b parallel to the mounting direction, the guide inclined surface 3242a is located on the front end side of the upper abutment surface 3242b in the mounting direction and intersects the upper abutment surface 3242b, and the position of the front end of the guide inclined surface 3242a in the mounting direction is lower than the position of the rear end thereof in the mounting direction. During the ink cartridge mounting process, the guide inclined surface 3242a and the upper abutting surface 3242b are engaged with the two side wall plates of the lower side portion 52c, and the end of the lower side portion 52c near the front end portion 32 can move along the guide inclined surface 3242a and then slide onto the upper abutting surface 3242 b. The guide slope 3242a and the upper abutment surface 3242b serve as guides and supports, and further enhance the engagement of the ink cartridge with the lower side portion 52c on the basis of the side wall 3241.

The ink cartridge of the present embodiment is provided with the stopper arm 3231 at the front end portion 32 to stopper the electrical connection portion 52t in the plumb direction, and the side stopper wall 3241 for stopping the electrical contact portion in the width direction of the ink cartridge is introduced to the front end portion 32, so that the chip 33 and the electrical connection portion 52t can be ensured to be correctly joined.
