[0049] see Figure 5 , the consumables chip 41 of this embodiment has a substrate, and a control module 42 and a storage module 43 are arranged in the consumables chip 41 , wherein the storage module 43 includes a first data storage area 44 and a second data storage area 45 . In this embodiment, the control module 42 can be a device with data processing functions such as a microprocessor (MCU), and the storage module 43 can be a non-volatile memory, such as EEPROM or Flash, etc., or a ferroelectric memory, etc., and stores There are multiple storage areas in the module 43, which can store constant data and variable data. For example, the constant data includes data related to the consumable container itself, and the constant data will not change with the use of the consumable container Data, such as the serial number of the consumable chip, the color of the consumable stored in the consumable container, the model of the printer to which the consumable container is applicable, ...

[0062] see Figure 9 , the consumable chip 60 of this embodiment has a substrate 61, on which a plurality of contacts 62 are arranged, and the plurality of contacts 62 are used to electrically connect with the contacts on the printer and realize the communication between the control module and the printer. An electronic module is arranged on the substrate 61. The electronic module includes a control module and a storage module. The control module can also be a chip with operating capabilities such as a microcontroller. The storage module can be a non-volatile memory, and two groups of serial number data.
[0063] A circular through hole 62 is disposed on the substrate 61 , and two signal contacts 63 are disposed on the inner wall of the through hole 62 . Preferably, the two signal contacts 63 are respectively located at opposite positions on the inner wall of the through hole 62 . A metal conductor is also arranged in the through hole 62. In this embodiment, the metal conduct...

[0067] see Figure 10 The consumable chip in this embodiment has a substrate 71, two through holes 72 are arranged on the substrate 71, and a signal contact 75 is respectively arranged on the inner walls of the two through holes 72, preferably, two signal contacts 75 are respectively located on the surface close to the other through hole 72 . In addition, both signal contacts 75 extend along the thickness direction of the substrate 71 .
[0068] The metal conductor 73 is used to electrically connect two signal contacts 75. In this embodiment, the two ends of the metal conductor 73 are respectively provided with an elastic arm 74, and the two elastic arms 74 abut on the two contacts 75 respectively. An electrical connection of the two contacts 75 is thereby achieved. Since two through holes 72 are provided on the substrate 71 , the two elastic arms 74 can extend into the through holes 72 .
[0069] From Figure 10 It can be seen that the two signal contacts 75 are respectiv...
