Embodiment one

Fig. 2 is the schematic diagram of the chip in embodiment one.Fig. 3 is the schematic diagram of the chip substrate of one chips of embodiment. Fig. 4 is the partial schematic diagram of the articulamentum of the chip in embodiment one.

As shown in Figures 2 to 4, chip 20 includes articulamentum 21, chip substrate 22, memory (not shown).Chip 20 are detachably mounted in the mounting portion 90 (as shown in Figure 1) of printer.Mounting portion 90 is a part for printer.Mounting portion 90 have contact pilotage portion 91, ink supply 92, joint 93.P is installed in mounting portion 90 chip 20 in assembly direction, with installation side The direction perpendicular to P is width direction T.Direction both perpendicular to installation direction P, width direction T is thickness direction Q.

As shown in figure 3, installation direction P, width direction T, thickness direction Q are a three-dimensional system of coordinates；Installation direction P is also It is the thickness of the width direction of the length direction of chip 20, width direction T i.e. chip 20, thickness direction Q i.e. chip 20 Spend direction.Chip substrate 22, the direction of articulamentum 21 are consistent with the direction of chip 20.It is provided with terminal group on chip substrate 22 200 (also referred to as terminals 200), terminal group 200 is electrically connected with the contact pilotage 911 in contact pilotage portion 91, the part in terminal group 200 Terminal is connected with memory, and memory is for storing and 30/ chip of print cartridge, 20 relevant information.

In the present embodiment, terminal group 200 has the 9th terminals 209 of first terminal 201-.In the upper ends installation direction P subgroup 200 arrangements are in 2 rows, as shown in figure 3, first terminal 201- forth terminals 204 come in the first row L1 of installation direction P, the 5th The 9th terminals 209 of terminal 205- come in the second row L2 of installation direction P.On installation direction P, second row L2 is in first row L1 Front end side.On width direction T, the 9th terminals 209 of first terminal 201- are spaced, i.e. 200 (first ends of terminal group The 9th terminals 209 of sub- 201-) the spaced arrangement successively on the width direction T perpendicular to installation direction P.In terminal group 200 Terminal can reach by conductive part and chip substrate memory or electric components electrical connection function.

The effect of terminal in terminal group 200 and function are as follows：

Terminal 201：First installation detection terminal；

Terminal 202：Reseting terminal；

Terminal 203：Clock terminal；

Terminal 204：Second installation detection terminal；

Terminal 205：Third installs detection terminal；

Terminal 206：Power supply terminal；

Terminal 207：Ground terminal；

Terminal 208：Data terminal；

Terminal 209：4th installation detection terminal.

Terminal 202,203,207,208 is connected with memory, for mutual transmission telecommunications number and letter between printer Breath interaction, runs under the voltage of 3.3V.Wherein, terminal 207 is ground terminal, voltage 0V.Terminal 207 not with memory phase Connection.Those skilled in the art is not it is understood that can also have terminal 207 in terminal group 200.

Installation detection terminal is divided into 2 groups, and it is first group of peace that the first installation detection terminal 201, second, which installs detection terminal 204, Fill detection terminal；It is second group of installation detection terminal that third, which installs detection terminal the 205, the 4th and installs detection terminal 209,.First group The voltage for the 2.4V that installation detection terminal 201,204 is inputted by printer (passing through contact pilotage 911), second group of installation detection terminal 205,209 by the voltage of the 42V of printer (passing through contact pilotage 911) input.The number and terminal group of contact pilotage 911 in contact pilotage portion 91 200 is corresponding, is also 9, the function industry of contact pilotage 911 is also corresponding to it.

Further, as shown in figure 3, being provided with fixed part 221,222,223 on chip substrate 22.Fixed part 221,222, 223 be the notch on chip substrate 22, is provided with protrusion accordingly on box body 35, protrusion can with fixed part 221,222, 223 match, to have the function that 22/ chip 22 of chip substrate is fixed on box body 35.

Further, as shown in figure 3, chip substrate 22 is in rectangular shape substantially, there is the 6th face 22f of the first face 22a- (being not shown in figure the 6th face 22f).There is terminal group 200 on first face 22a.Memory can be located at the 6th faces the first face 22a- On any one face in 22f.Terminal group 200 (terminal 200) is arranged on the first face 22a, and terminal group 200 passes through articulamentum 21 It is connect with contact pilotage 911.
