FLUID EJECTION DEVICE, DRIVING METHOD OF FLUID EJECTION DEVICE, AND OPERATING INSTRUMENT
First Claim
1. A fluid ejection device comprising:
- a fluid chamber whose capacity is variable;
an inlet flow path and an outlet flow path communicating with the fluid chamber;
a capacity changing unit which changes the capacity of the fluid chamber;
a fluid supplying unit which supplies fluid to the inlet flow path;
a fluid ejection opening disposed at an end of the outlet flow path opposite to an end communicating with the fluid chamber;
a vibrating unit which vibrates a component in the vicinity of the fluid ejection opening;
a vibration detecting unit which detects the level of vibration of the component in the vicinity of the fluid ejection opening; and
an operation control unit which controls operation of the capacity changing unit based on the level of the vibration detected by the vibration detecting unit.

14. A driving method of a fluid ejection device comprising:
the fluid ejection device including a fluid chamber whose capacity is variable, an inlet flow path and an outlet flow path communicating with the fluid chamber, a capacity changing unit which changes the capacity of the fluid chamber, a fluid supplying unit which supplies fluid to the inlet flow path, a fluid ejection opening disposed at an end of the outlet flow path opposite to an end communicating with the fluid chamber, a vibrating unit, a vibration detecting unit, and an operation control unit; vibrating a component in the vicinity of the fluid ejection opening by the vibrating unit; detecting the level of vibration of the component in the vicinity of the fluid ejection opening by the vibration detecting unit; and controlling operation of the capacity changing unit based on the level of the vibration detected in the vibration detecting step by the operation control unit.
