As shown in fig. 16, the chip 3 has a first terminal 31, a second terminal 32, a third terminal 33, and an extension terminal 34. Specifically, the first terminals 31 are a reset terminal 311, a clock terminal 312, a power terminal 313, a ground terminal 314 and a data terminal 315, respectively, and further, some of the terminals in the first terminals 31 are connected to a memory (not shown in the figure) of the chip 3; the second terminals 32 are a left high voltage terminal 321 and a right high voltage terminal 322, respectively; the third terminals 33 are a left attachment detection terminal 331 and a right attachment detection terminal 332, respectively; the extended terminals 34 are left and right

extended terminals

341 and 342, respectively.

In the embodiment, the chip 3 has the notch 35, and when the ink cartridge 2 is mounted on the cartridge holder 1, the notch 35 can accommodate a part of the contact portion 11 on the cartridge holder 1, and this structure can better achieve the stability of the electrical connection between the chip 3 and the contact portion 11.

As shown in fig. 16, more specifically, the first terminals 31, the second terminals 32, and the third terminals 33 are arranged in three rows in the mounting direction, and in the direction opposite to the mounting direction, in this order: a first row L1, a second row L2, a third row L3. The second terminals 32 are located in the first row L1, and the third terminals 33 and a part of the first terminals 31 (specifically, the reset terminals 311, the clock terminals 312) are located in the third row L3. Another portion of the first terminals 31 (specifically, the power terminal 313, the ground terminal 314, and the data terminal 315) is located in the second row L2. With this structural design, the first terminal 31 can be distanced from the second terminal 32 to further prevent the possibility of a short circuit between the second terminal 32 (high voltage) and the first terminal 31.

As shown in fig. 16, wherein, in the present embodiment, the extended terminals 34 are located at the third row L3 and between the third row L3 and the second row L2. The left extension terminal 341 is disposed around the left attachment detection terminal 331, and by this configuration, if the ink cartridge 2 is obliquely attached to the cartridge holder 1, one of the contact pins of the contact pin portion 11 corresponding to the left attachment detection terminal 331 may come into contact with the left extension terminal 341, and if it comes into contact with the left extension terminal 341, the printer may detect that the contact pin of the contact pin portion 11 is not in contact with the correct terminal, and thus detect that the ink cartridge 2 is obliquely attached. The right extension terminal 342 is disposed around the right attachment detection terminal 332, and has the same function as the left extension terminal 341, which will not be described again. Examples are: the left attachment detection terminal 331 and the right attachment detection terminal 332 are electrically connected, and if the ink cartridge 2 is correctly attached, the contact pins (not shown) in the contact pin portion 11 corresponding to the left attachment detection terminal 331 and the contact pins (not shown) in the contact pin portion 11 corresponding to the right attachment detection terminal 332 can be electrically connected, for example: if a 3.6V square wave is input to one stylus of the stylus portion 11, the same 3.6V square wave is detected at the other stylus. If the ink cartridge 2 is mounted in the cartridge holder 1 with a bias such that one of the contact pins contacts either the left 341 or right 342 extension terminals, no electrical connection occurs between the two contact pins and no square wave condition is detected.

Further, in the present embodiment, the extension terminals 34 may be connected to any one of the first terminals 31, respectively. For example: the left extension terminal 341 is connected to the reset terminal 311, and the right extension terminal 342 is connected to the data terminal 315. The left extension terminal 341 may be connected to any one of the clock terminal 312, the power supply terminal 313, the ground terminal 314, and the data terminal 315; the right extension terminal 342 may be connected to any one of the reset terminal 311, the clock terminal 312, the power supply terminal 313, and the ground terminal 314.

As shown in fig. 17, another structure design of the chip 3 is provided in the present embodiment, specifically, the position of the extending terminal 34 is located on the first row L1 and between the first row L1 and the second row L2. The extension terminal 34 is connected to a detection circuit in the memory, and has a function of detecting a short circuit, and detects whether or not a short circuit occurs between the extension terminal 34 itself and the second terminal 32. If a short circuit occurs, it can be detected in time to avoid the high voltage applied to the second terminal 32 being applied to the first terminal 31, which may cause data damage inside the chip 3. Further, the extension terminal 34 is connected to an internal program of the memory of the chip 3. If a short circuit occurs between the extended terminal 34 and the second terminal 32, the chip 3 cannot be normally used.

As shown in fig. 18, another structural design of the chip 3 is provided in this embodiment, specifically, the chip 3 has a notch 35, and the notch 35 is respectively located at the left and right ends of the chip 3.

Further, a part of the first terminals 31 (specifically, the power terminal 313, the ground terminal 314, and the data terminal 315) is located in the first row L1; the second terminals 32 are located in a second row L2; another part (specifically, the reset terminal 311, the clock terminal 312) of the first terminals 31 is located in the third row L3; the third terminals 33 are located in the fourth row L4. Among them, the extension terminal 34 is disposed on the third row L3, and is disposed in the same row as another portion (specifically, the reset terminal 311, the clock terminal 312) in the first terminal 31.

Specifically, in the present embodiment, the left extension terminal 341 is connected to the reset terminal 311 through a left thin wire connection portion, and the right extension terminal 342 is connected to the clock terminal 312 through a right thin wire connection portion. The left extension terminal 341 is connected to any one of the reset terminal 311, the clock terminal 312, the power supply terminal 313, the ground terminal 314, and the data terminal 315; the right extension terminal 342 is connected to any one of the reset terminal 311, the clock terminal 312, the power supply terminal 313, the ground terminal 314, and the data terminal 315.

As shown in fig. 19, another structure design of the chip 3 is provided in the present embodiment, specifically, the positions of the extended terminals 34 are located on the third row L3, the fourth row L4 and the upper portion of the fourth row L4. The extension terminal 34 has a function of detecting a short circuit, and detects whether or not a short circuit occurs between the extension terminal 34 itself and the second terminal 32. If a short circuit occurs, it can be detected in time to avoid the high voltage applied to the second terminal 32 being applied to the first terminal 31, which may cause data damage inside the chip 3. Further, the extension terminal 34 is connected to an internal program of the memory of the chip 3. If a short circuit occurs between the extended terminal 34 and the second terminal 32, the chip 3 cannot be normally used.
