Member including pad electrode, ink cartridge and recording apparatus
A member includes a plurality of pad electrodes and a casing, wherein the plurality of pad electrodes are mounted on the casing and are rotatable relative to the casing on the casing.
1. An ink cartridge comprising a casing to which an electrode unit, including a plurality of pad electrodes, is mounted and configured to store ink therein,
wherein the electrode unit is rotatable relative to the casing in a plane provided with the plurality of pad electrodes.
2. An ink cartridge according to claim 1 , further comprising a first portion, a second portion opposite to the first portion, a third portion connecting said first portion and said second portion with each other, as portions facing an outside of the ink cartridge,
wherein the electrode unit is provided on the third portion.
3. An ink cartridge according to claim 1 , wherein the electrode unit moves in a direction perpendicular to the plane by rotating the electrode unit relative to the casing.
4. An ink cartridge according to claim 1 , wherein a gap is provided below the electrode unit, and between the casing and the electrode unit.
5. A recording apparatus comprising the ink cartridge according to claim 1 .
6. An ink cartridge according to claim 1 , wherein the electrode unit is provided with a shaft hole, a shaft of the casing passes through the shaft hole, and the electrode unit rotates relative to the casing about the shaft as a rotational axis.
7. An ink cartridge mountable to a mounting portion including an ink receiving tube and a plurality of electrical connecting portions, said ink cartridge comprising: a casing to which an electrode unit, including a plurality of pad electrodes electrically connectable to the plurality of electrical connecting portions, is mounted and configured to store ink,
wherein the electrode unit is rotatable relative to the casing in a plane provided with the plurality of pad electrodes.
8. An ink cartridge according to claim 7 , further comprising a first portion which is a leading portion when the ink cartridge is mounted on the mounting portion along a mounting direction, a second portion on the opposite side of the first portion, and a third portion connecting the first portion and the second portion with each other, as portions facing an outside of the ink cartridge,
wherein the electrode unit is provided on the third portion.
9. An ink cartridge according to claim 8 , wherein the plurality of pad electrodes are movable in a direction different from the inserting direction by the rotation relative to the casing.
10. An ink cartridge according to claim 7 , wherein the plurality of pad electrodes are electrically connected to the electrical connecting portions by rotating the electrode unit relative to the casing.
11. An ink cartridge according to claim 7 , wherein a gap is provided below the electrode unit, and between the casing and the electrode unit.
12. An ink cartridge according to claim 7 , wherein the electrode unit is provided with a shaft hole, a shaft of the casing passes through the shaft hole, and the electrode unit rotates relative to the casing about the shaft as a rotational axis.
13. An ink cartridge according to claim 7 , wherein a rotational axis of the electrode unit is substantially perpendicular to the mounting direction of the ink cartridge.
