Abstract
The liquid delivery device adapted for installation in a liquid jetting device that has a number N of liquid receiving portions, where N is an integer equal to 2 or greater, comprises an electrical device that returns a response signal in response to a driving signal from the liquid jetting device; a number N of liquid delivery portions that deliver liquid to the liquid receiving portions; and a number N of sets of terminals provided in correspondence with the liquid delivery portions; wherein the electrical device receives the driving signal and transmits the response signal, via one set of terminals among a number M of sets of terminals among the N sets of terminals, where M is an integer equal to 2 or greater but not greater than N.
Claims12
A liquid delivery device adapted for installation in a liquid jetting device that has a number N of liquid receiving portions, where N is an integer equal to 2 or greater, comprising:
- an electrical device that returns a response signal in response to a driving signal from the liquid jetting device;
- a number N of liquid delivery portions that deliver liquid to the liquid receiving portions;
- and
- a number N of sets of terminals provided in correspondence with the liquid delivery portions;
- wherein the electrical device receives the driving signal and transmits the response signal, via one set of terminals among a number M of sets of terminals among the N sets of terminals, where M is an integer equal to 2 or greater but not greater than N.
An electrical circuit adapted for installation in a liquid jetting device that has a number N of liquid receiving portions, and a number N of sets of device-side terminals provided in correspondence with the liquid receiving portions, where N is an integer equal to 2 or greater, the electrical circuit comprising:
- an electrical device that returns a response signal in response to a driving signal from the liquid jetting device;
- and
- a number M of sets of circuit-side terminals that electrically connects respectively to M sets of terminals among the N sets of device-side terminals when installed in the liquid jetting device, where M is an integer equal to 2 or greater;
- wherein the electrical device receives the driving signal and transmits the response signal, via one set of circuit-side terminals among the M sets of circuit-side terminals.
A liquid jetting system comprising:
- a liquid jetting device;
- and
- an ink delivery device adapted for installation in the liquid jetting device;
- wherein the liquid jetting device has:
- a number N of liquid receiving portions where N is an integer equal to 2 or greater;
- a number N of sets of device-side terminals provided in correspondence with the liquid receiving portions;
- and
- a sensor driving circuit that outputs a driving signal from any terminal of one set of terminals selected from the N sets of device-side terminals, and receives a response signal from any terminal of the selected one set of terminals;
- the ink delivery device has:
- an electrical device that returns a response signal in response to the driving signal;
- and
- a number M of sets of delivery device-side terminals that electrically connects respectively to M sets of terminals among the N sets of jetting device-side terminals when the ink delivery device is installed in the liquid jetting device, where M is an integer equal to 2 or greater;
- and wherein the electrical device receives the driving signal and transmits the response signal, via one set of delivery device-side terminals among the M sets of delivery device-side terminals.
