Ink jet recording apparatus, ink or solvent cartridge, and bottle included in cartridge

摘要

An object is to prevent the occurrence of contact failure between a cartridge equipped with a recording medium and an ink jet recording apparatus. A bottle body is crushed to reduce the volume thereof when an ink or solvent is sucked out of the bottle body. A bottle has a neck and a mouth. The neck is rigid. The ROM unit records therein an ink or solvent type, a serial number, the capacity of the bottle, and the amount of remaining ink or solvent. The ROM unit has first and second arms, and freely movably attached to the neck by the first and second arms. A positioning hole is formed on a ROM holder body which houses therein a recording medium. The positioning hole positions the ROM holder body in cooperation with a positioning pin of a reservoir.

主权项

1. A cartridge for a continuous type ink jet recording apparatus, the cartridge being detachably received in a cartridge receiving unit of the continuous type ink jet recording apparatus so as to replenish the continuous type ink jet recording apparatus with an ink or solvent, the cartridge comprising:
a body portion having an internal space storing an ink or solvent therein, the body portion at least partially having flexibility; a rigid portion having a fluid path inside thereof and projecting in an axial direction from the body portion, the fluid path communicating with the internal space of the body portion, the rigid portion having a smaller diameter and higher rigidity than the body portion; and a recording medium unit having a recording medium capable of recording information about the cartridge, wherein the recording medium unit is detachably engaged with the rigid portion at a locking position by a recess-boss engagement so as to be locked in the axial direction and in a circumferential direction of the rigid portion by the recess-boss engagement, and wherein the recording medium unit has a first surface having a first terminal of the recording medium, the first surface being substantially parallel to an insertion direction of the cartridge, the first terminal being in contact with a second terminal disposed on a second surface provided at the cartridge receiving unit when insertion of the cartridge into the cartridge receiving unit is completed, the second surface being substantially parallel to the insertion direction of the cartridge.
