Claims

[Scope of utility model registration request]

In a printer print head configured with a mechanical amplification mechanism that transmits the expansion/contraction/thickness motion of an electrostrictive or piezoelectric element in the axial direction of a buckling spring having an operating element as an output end and amplifies the displacement, the buckling spring is one end of the mechanical amplification mechanism. A print head comprising a plurality of springs integrated with a common fixed end.
