を必要とする。(Prior Art and its Problems) Conventionally, as drive devices using electromechanical conversion elements, there are printing devices such as printer print heads, and switches such as relays and switches. For example, most dot-impact printer print heads use electromagnets or permanent magnets as the Ois source. However, this method has the disadvantage of requiring a large amount of input energy compared to the required energy due to copper loss and iron loss during driving, and low energy conversion efficiency. For this reason, recently, a mechanism that uses an electrostrictive element or a piezoelectric element as a drive source to reduce power consumption and heat generation t and enables high-speed operation has been considered. but,
In this method, the elongation of the electrostrictive or piezoelectric element when excited is as small as 0.01 m, so the elongation of the electrostrictive or piezoelectric element is as small as 0.01 m, which is 0.3 m or more, which is necessary for the output end effecting element of a normal printer print head or relay mechanism. A displacement magnification means is required to obtain a displacement of 0.5 degrees.

ためその分を補う長い湾曲ばね２６が必要となる。In response to this requirement, there is a mechanism described in Japanese Patent Laid-Open No. 113625/1983 as shown in FIG. 7 that has been proposed in the past. In FIG. 7, both ends of a curved spring 26 which is curved upward (in the printing direction) by an adjusting screw 25 are fixed to a holding element 27, and one of the holding elements 27 is seated on a piezoelectric crystal device 28, and the other is fixed and held. Seated in section 29. In this structure, the bending spring 26 is bent by excitation of the piezoelectric crystal device 28, and a printing needle 30 provided at the center of the bending spring 26 is driven. In this method, when displacement is applied in the axial direction of the curved spring 26, a large amount of deflection can be obtained at the center of the curved spring 26, as is clear from the well-known buckling theory, and the structure is also simple. However, in a mechanism using such a buckling spring, when the displacement tt-ε of the piezoelectric crystal 28 and the length of the curved spring 26 are L, the amount of deflection S at the center of the curved spring 26 is geometrically 8 = 44]/rc, but since the force displacement transmission is lost due to the deformation of the fixed holding portion 29, a long curved spring 26 is required to compensate for the loss.

構が得られる。Further, since the electrocrystal device 28 is directly connected to the curved spring 26, the entire mechanism becomes large when combined with the length of the curved spring 26, which makes it difficult to miniaturize printer print heads, relays, etc. There is an increase 4@ organization in the Gitchiya fraud issue. In FIG. 8, it is composed of two lever arms 32 as displacement amplifying means connected to both ends of an electrostrictive or piezoelectric element 31 in the direction of expansion and contraction, and a beam 33 supported so as to be sandwiched at the tip of each lever arm 32. There is. With this structure, an enlarged displacement is given to each lever arm 32 in the axial direction of the beam 33 by electrostriction or excitation of the piezoelectric element 31, and further, by deformation of the beam 33, the printing needle 34 at the center of the beam 33 is expanded. 1ζ displacement occurs. With this method, even if the length of the beam is long, it is possible to obtain a next-smallest mechanism with a large displacement amplification factor.

要がある。However, in this structure, since a movable body such as the lever arm 32 is disposed outside the substrate 35 serving as a fixed portion, it becomes difficult to position the printing needle 34 as an output end and the substrate 35. That is, a printer is usually constructed from a plurality of heads, and for this purpose, the printing needles of each head must be arranged within about 0.05 m5+.

An in-flight amplification mechanism is obtained which is characterized in that the element is provided.

があり、その梁はベースに位置決めされて接続される。(Detailed Description of Configuration) The present invention has solved the conventional problems by adopting the above-mentioned configuration. First, a lever arm is connected to a base that fixes and supports one end of the electrostrictive or piezoelectric element in the expansion and contraction direction through a displacement transmission means that transmits displacement and serves as a fulcrum. Further, both ends of the electrostrictive or pressure element in the expansion/contraction direction are connected to the lever arm via another displacement transmission means. There is a beam supported between the other end of the TYC lever arm and the other end of the base, and the beam is positioned and connected to the base.

変位を得る。Therefore, due to the excitation of the electrostrictive or piezoelectric element, the lever arm rotates using the displacement transmitting means connected to the base as a fulcrum according to the Jin principle, and the displacement is amplified at the connection part with the beam at the other end of the lever arm. Then, displacement is transmitted from the lever arm in the axial direction of one end of the beam, and the beam is further amplified and deformed, as is clear from buckling theory. At this time, the operating element as the output end at the center of the beam obtains amplification displacement at a more accurate position than the base.

において、前記電歪あるいは圧電素子の伸縮方向一端を
固定（支持するベースと、前記電歪あるいは圧電素子の
他端と前記ベースに接続した変位増幅手段としてのレバ
ーアームと、そのレバーアームとベースで挾むように支
持された変位増幅手段としての梁とから構成され、その
梁には出力端としての作用素子が設けられていることを
特徴とする機械的増幅機構。In an amplification mechanism that amplifies and drives the motion of an electrostrictive or piezoelectric element, one end of the electrostrictive or piezoelectric element in the expansion/contraction direction is fixed (a base that supports it, and the other end of the electrostrictive or piezoelectric element is connected to the base for displacement). It consists of a lever arm as an amplifying means, and a beam as a displacement amplifying means supported between the lever arm and a base, and the beam is provided with an operating element as an output end. Mechanical amplification mechanism.
