Liquid ejection apparatus and liquid cartridges

摘要

A liquid ejection apparatus includes a liquid ejection head that ejects liquid, a hollow needle that communicates with the liquid ejection head, a moving mechanism that moves the hollow needle or a liquid cartridge such that the hollow needle penetrates a sealing member of the liquid cartridge, a reader that reads a data stored in a memory, and a controller that controls a speed of the hollow needle relative to the sealing member based on the data read by the reader.

主权项

1. A liquid ejection apparatus, to which a liquid cartridge is detachably attached,
the liquid cartridge comprising:
a liquid storing portion configured to store liquid;a communication portion having an opening, which communicates an interior of the liquid storing portion with an exterior of the liquid storing portion; anda sealing member configured to seal the opening of the communication portion, the liquid ejection apparatus comprising:
a liquid ejection head configured to eject liquid;a hollow needle configured to communicate with the liquid ejection head; anda moving mechanism configured to move at least one of the hollow needle and the liquid cartridge, such that the hollow needle penetrates the sealing member of the liquid cartridge, wherein the liquid cartridge further comprises a particular memory configured to store particular data for determining a speed of the hollow needle relative to the sealing member when the moving mechanism moves the at least one of the hollow needle and the liquid cartridge to penetrate the sealing member of the liquid cartridge with the hollow needle, wherein the liquid ejection apparatus further comprises:
a reader configured to read the particular data stored in the particular memory; anda controller configured to control a speed of the hollow needle relative to the sealing member when the moving mechanism moves the at least one of the hollow needle and the liquid cartridge to penetrate the sealing member of the liquid cartridge with the hollow needle based on the particular data read by the reader, wherein the particular data comprises data relating to a material of the sealing member of the liquid cartridge.
