The liquid container in accordance with claim 3, wherein the determination use terminal includes an input terminal that is adapted to receive from the liquid jetting device an input signal for determining whether there exists the installed state or not and an output terminal that is adapted to output, in response to the input signal, a response signal indicating that there exists the installed state, andthe installation status notifier portion is adapted to notify the liquid jetting device that there exists the non-installed state by bringing at least either one of the input terminal and the output terminal to a high-impedance state. 5. The liquid container in accordance with claim 1, further comprising: a determination use terminal adapted to electrically connect to the liquid jetting device in the installed state, and to be used by the liquid jetting device to determine whether there exists the installed state or not;wherein the installation status notifier is adapted to notify the liquid jetting device that there exists the non-installed state by outputting a signal indicating the non-installed state via the determination use terminal. 6. The liquid container in accordance with claim 5, wherein the determination use terminal includes an input terminal contact portion and an output terminal contact portion and the input terminal contact portion is adapted to receive from the liquid jetting device an input signal for determining whether the installed state exists or not; and the output terminal contact portion is adapted to output in response to the input signal a response signal indicating that there exists the installed state; andthe installation status notifier portion is adapted to notify the liquid jetting device that there exists the non-installed state by outputting from the output terminal contact portion a signal indicating the non-installed state, instead of the response signal. 7. The liquid container in accordance with claim 1, wherein, the installation status notifier portion comprises: a first terminal adapted to electrically connect to the liquid jetting device in the installed state; andwherein the installation status notifier portion is adapted to notify the liquid jetting device whether there exists the installed state or the non-installed state, depending on whether the potential on the first terminal is a prescribed potential or not. 8. The liquid container in accordance with claim 7, wherein: the installation status notifier portion comprises a second terminal that in the installed state is supplied with the prescribed potential; andthe installation status notifier portion has a first switching portion that is adapted to switch a connection of the first terminal and the second terminal between a state of continuity and a state of non-continuity. 9. The liquid container in accordance with claim 1, further comprising: an operation receiving portion that is adapted to receive operations by a user, andwherein the information rewriting portion is adapted to rewrite the liquid information when a user operation has been received. 10. The liquid container in accordance with claim 9, further comprising: a supply hole situated on a first side of the container body, for supplying the liquid to the liquid jetting device,wherein the operation receiving portion is disposed to an opposite side from the first side of the container body. 11. The liquid container in accordance with claim 1, wherein the information rewriting portion is adapted to rewrite the liquid information when a value of the liquid information has met a prescribed condition. 12. The liquid container in accordance with claim 1, wherein the information rewriting portion is adapted to rewrite the liquid information when an update count by the liquid jetting device of the liquid information stored in the memory exceeds a prescribed count. 13. The liquid container in accordance with claim 1, wherein the liquid information includes residual amount information for identifying a residual amount of liquid contained in the container body. 14. The liquid container in accordance with claim 1, wherein the container body is provided with a refilling hole for refilling the liquid. 15. The liquid container in accordance with claim 14, further comprising: a supply hole situated on a first side of the container body, for supplying the liquid to the liquid jetting device,wherein the refilling hole is disposed to an opposite side from the first side of the container body. 16. The liquid container in accordance with claim 1, further comprising: a memory terminal adapted to electrically connect the memory with the liquid jetting device in the installed state; anda second switching portion that is adapted to switch a connection of the memory and the memory terminal between a state of continuity and a state of non-continuity,wherein the second switching portion places the connection of the memory and the memory terminal in a state of non-continuity while the information rewriting portion is rewriting the liquid information. 17. The liquid container in accordance with claim 1, wherein the installation status notifier portion is adapted to notify the liquid jetting device to acknowledge the non-installed state during a prescribed time interval that includes an interval in which the information rewriting portion is rewriting the liquid information. 18. The liquid container in accordance with claim 1, further comprising: a board adapted for installation in a liquid jetting device. 19.
