Abstract

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.

First claim

What is claimed is:

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.

2. The cartridge for the ink jet recording apparatus according to claim 1 , further comprising:
a mouth having a discharge port for discharging the ink or solvent stored in the body portion to the outside; and
a neck interposed between the mouth and the body portion, the neck having a larger diameter than the mouth,
wherein the neck constitutes the rigid portion and the recording medium unit is disposed on the neck.

3. The cartridge for the ink jet recording apparatus according to claim 2 , wherein the mouth, the neck, and the body portion are integrally molded.

4. The cartridge for the ink jet recording apparatus according to claim 1 , wherein
the body portion has a plurality of flexible side faces and a plurality of corner portions shared by adjacent ones of the side faces, and
the side faces are deformed prior to the corner portions in the body portion in response to outflow of the ink or solvent stored in the body portion to the outside.

5. The cartridge for the ink jet recording apparatus according to claim 1 , further comprising:
a mouth for being received in the cartridge receiving unit; and
wherein the mouth constitutes the rigid portion, and
when the ink or solvent inside the body portion is sucked out by a pump of the ink jet recording apparatus, the body portion is deformable to reduce the volume thereof in response to the suction.

6. The cartridge for the ink jet recording apparatus according to claim 1 ,
wherein the cartridge further includes a mouth for being received in the cartridge receiving unit and the body portion is deformable to reduce the volume thereof in response to suction performed by a pump of the ink jet recording apparatus,
the mouth constitutes the rigid portion, and
the mouth is sealed by a rubber stopper that allows a hollow needle standing on a bottom of the cartridge receiving unit to penetrate therethrough when the mouth is received by the cartridge receiving unit.

7. The cartridge for the ink jet recording apparatus according to claim 1 , wherein the recording medium records an identification information specific to the cartridge, the identification information being read through the first terminal and the second terminal by the continuous type ink jet recording apparatus when the first terminal is in contact with the second terminal.

8. The cartridge for the ink jet recording apparatus according to claim 1 , wherein when insertion of the cartridge into the cartridge receiving unit is completed, the ink jet recording apparatus sucks out the ink or solvent from the cartridge through the fluid path extended along the insertion direction of the cartridge in the rigid portion.

9. The cartridge for the ink jet recording apparatus according to claim 1 , wherein the recording medium unit has a misinsertion prevention mechanism for preventing the cartridge from being incorrectly inserted into the cartridge receiving unit, the misinsertion prevention mechanism interfering with the cartridge receiving unit during insertion of the cartridge.

10. The cartridge for the ink jet recording apparatus according to claim 9 , wherein
the cartridge is an ink cartridge storing the ink therein,
the ink cartridge is completely inserted into an ink side cartridge receiving unit, and
the misinsertion prevention mechanism provided in the ink cartridge interferes with a solvent side cartridge receiving unit during insertion of the ink cartridge, to prevent the ink cartridge from being incorrectly inserted into the solvent side cartridge receiving unit.

11. The cartridge for the ink jet recording apparatus according to claim 10 , wherein the misinsertion prevention mechanism is a first obstruction portion provided in the ink cartridge, the first obstruction portion interfering with a second obstruction portion provided in the solvent side cartridge receiving unit during insertion of the ink cartridge.

12. The cartridge for the ink jet recording apparatus according to claim 10 , wherein the ink cartridge is the same size and shape as the solvent cartridge with the exception of the recording medium unit.

13. The cartridge for the ink jet recording apparatus according to claim 12 , wherein a shape of the recording medium unit is different between the ink cartridge and the solvent cartridge.

14. The cartridge for the ink jet recording apparatus according to claim 1 , further comprising:
an attachment configured to be attached to the rigid portion, the attachment having a half-housing shape which covers a side face of the body portion,
wherein the cartridge is received in the cartridge receiving unit with the attachment attached to the rigid portion.

15. A bottle detachably received in a reservoir of a continuous type ink jet recording apparatus so as to replenish the ink jet recording apparatus with an ink or solvent, the bottle comprising:
a bottle body having an internal space storing an ink or solvent therein, the bottle body at least partially having flexibility; and
a mouth for discharging the ink or solvent inside the bottle body to the outside, the mouth projecting from the bottle body,
wherein the mouth has higher rigidity than the bottle body,
the mouth has an attachment portion to which a recording medium unit having a recording medium capable of recording information about the bottle is detachably fixed by a recess-boss engagement,
the bottle is received in the reservoir with the recording medium unit fixed to the attachment portion by the recess-boss engagement so as to be locked in a circumferential direction about the mouth and in an axial direction of the mouth and bottle body by the recess-boss engagement, and 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 a cartridge receiving unit when insertion of the cartridge into the cartridge receiving unit is completed, the second surf
