Abstract
Claims
1. A cartridge, An adapter that is detachably attached to the cartridge mounting section of the printing device, The adapter comprises a liquid container that is detachably engaged with the adapter, The aforementioned adapter is An adapter engagement portion for detachably engaging a liquid container, An adapter terminal that can contact the device terminal of the cartridge mounting section, A liquid introduction section having an internal flow path in the cartridge mounting section, comprising an insertion opening into which a liquid introduction section having a device flow path valve mechanism for opening and closing the internal flow path is inserted, The adapter terminal is connected to the device terminal, and the liquid introduction part is inserted into the insertion opening, thereby attaching the adapter to the cartridge mounting part. The liquid container is a cartridge having a liquid inlet formed at the corner of the container on the far side in the insertion direction for inserting the adapter into the cartridge mounting portion, and on the side opposite to the side where the adapter is located.
2. A cartridge according to claim 1, The aforementioned adapter further, The bottom surface of the adapter where the insertion opening is formed, The adapter periphery surface intersecting the adapter bottom surface, The corner portion where the bottom surface of the adapter and the surrounding surface of the adapter intersect, the corner portion where the adapter terminals are located, A recess formed on the bottom surface of the adapter for receiving the cartridge mounting portion member, A guide portion formed on the circumferential surface of the adapter, which guides the horizontal insertion of the adapter into the cartridge mounting portion, A projection formed on the bottom surface of the adapter, which releases the restriction by the restricting mechanism of the cartridge mounting portion that restricts the movement of the adapter for inserting the liquid introduction portion into the insertion opening, by pushing the restricting member of the restricting mechanism in the direction of insertion, A cartridge having an adapter fixing portion formed on the periphery of the adapter for detachably fixing the adapter to the cartridge mounting portion.
3. A cartridge according to claim 1 or claim 2, The adapter engagement portion is a cartridge that engages with and disengages from the liquid container by elastic deformation.
4. The cartridge according to claim 3, The adapter engagement portion is a cartridge having a snap-fit structure.
5. The cartridge according to claim 3, The adapter engagement portion is a cartridge having a spring and an engagement portion attached to the spring that engages with the liquid container.
6. The cartridge according to claim 5, The aforementioned spring is either a coil spring or a leaf spring, in a cartridge.
7. The cartridge according to claim 5, The engagement portion is a cartridge having a rotating part that rotates when engaging and disengaging, and a rotating center that is the rotation center of the rotating part.
8. A cartridge according to claim 1 or claim 2, The adapter engagement portion engages with the liquid container engagement portion of the liquid container, which engages with and disengages the adapter engagement portion by elastic deformation.
9. A cartridge according to claim 1, The liquid container has a rear surface located on the front side in the insertion direction, The liquid inlet is located above the rear surface of the housing when the cartridge is mounted in the cartridge mounting section.
