摘要： A cavity plate for an ink-jet printhead includes a base material and a chamber sheet. An ink channel array constituting ink chambers is provided through the chamber sheet by a wire electric discharge machine, while an ink reservoir is formed on the base material by a wire electric discharge machine. Then, the chamber sheet and the base material are bonded to one another. Nozzles to eject ink may be created on a nozzle sheet, which is later connected to the chamber sheet. Alternatively, the nozzles may be directly provided on the chamber sheet. Thus, the cavity plate is provided having the ink chambers and the ink reservoir with high precision, without the increase in the production cost.

摘要： A driving device for a piezoelectric element is provided which attains lower power consumption, low heat generation and low cost. To displace a piezoelectric element, a first switching transistor is rendered ON by a control circuit. The electric charges flow in the piezoelectric element from the power supply through the first switching transistor. This state is continued until a sufficient amount of electric charges are stored in the piezoelectric element. To restore the piezoelectric element thus displaced, a second switching transistor is rendered ON under the condition where the first switching transistor is OFF. In this condition, a resonance circuit is formed by the piezoelectric element and the coil. When the electric charges are flowing in the coil and a predetermined period of time has elapsed after the second switching transistor is rendered ON, the control circuit renders the second switching transistor OFF, whereby the current flowing in the coil flows into the power supply.

At least a central portion of a stacked body is divided into a plurality of actuator portions 46a, 46b, and 46c by elongated holes 52 opened in the stacked direction.

摘要： A supporting plate, which is formed of a bendable plate material, includes coupling portions extending in the radial direction of the supporting plate and individually fixing armatures arranged radially, torsion bars paired so as to extend sideways from their corresponding coupling portions, at positions corresponding the respective proximal end portions of the armatures, and leaf spring members paired so as to be fixed to their corresponding armatures by means of the coupling portions, at positions inside the proximal end portions of the armatures, with respect to the radial direction, and to extend radially inward. The leaf spring members are arranged on either side of each armature. Each spring member has an arm portion bendable in the longitudinal direction of its corresponding armature. If the armatures are pulled and swung by means of electromagnetic devices, the torsion bars are twisted, and the leaf spring members are bent. Thus, the armatures are supported and subjected to a resilient force in the restoring direction.
