る。FIG. 1a is a perspective view illustrating the structure of a printing element related to the VC of the present invention. Metal mounting member t rc lower end? The fixed piezoelectric body 2 is the driving source for the printing operation. Piezoelectric body 2
A metal coupling member 31C is fixed to the upper end, and a 60mm metal movable member 4 and 5rr are both displaced by the piezoelectric body 2. The lower ends of the movable members 4 and 5, which are provided to operate as levers and transmit displacement when they are received, are attached to the mounting members via plate-shaped connecting parts. The upper ends of the movable member 4 and the connecting member 3vc are respectively dominant, and one end of the transmission member 6 and the metal plate 7 is solidified. The other end of 7 is fixed at a predetermined location of movable member 8/)o
At the tip of the J member 8, a metal rod wire 9 for printing dots is fixedly attached. When the mow pressure is applied, the F piezoelectric body 2 expands due to the electrostrictive effect, causing dimensional distortion, pushing up the coupling member 3 and giving a displacement of 5'/c to the movable member 4; The movable members 4 and 5 each act as a lever and produce the same displacement as indicated by broken arrows A and B at each upper end.These two displacements in opposite directions cause the transmission member 6 to move.
When the information is transmitted through the machining tool 7, the movable member 8 causes a rotational movement, and the wire moves in the same direction as the dashed arrow C to perform a dot printing operation. Mounting member l, movable member 4 work5. In addition, we have performed many 0-printing tests using spring steel as the metal material for the transmission member 6 and 7.
In particular, a large stress of 67 t is concentrated in the connecting part between the transmission member 6 and the joint 7 and the connecting member 5 and the mounting member 1 and the connecting member 3. Therefore, a spring steel material with high fire resistance against this repeated stress IC is selected and used.However, conventional printing elements using such materials v
crr, as the ambient temperature changes during operation, the transmission member 6
There are drawbacks such as breakage and damage 1a of the workpiece 7 or peeling of the piezoelectric body 2, and the dislocation of the tip of the wire 9, which prevents normal printing operation. First, when brazing is performed to secure each end N5 of the transmission member 6 and 7 to the movable member 4 and 5 and the movable member 8, the parts of the brazing become hot due to melting heat. As a result, a heat-affected zone is formed, and as a result, the fatigue strength of each end of the transmission member 6 and 7 is deteriorated due to causes such as embrittlement and cracking. For example, the fatigue limit with t is 80kg/ll1l! However, after melting, it deteriorated to half that amount, 40 kg/am2, or even less. When downsizing the 41fl element, the plate thickness of the transmission member 6 and 7 must be made thinner accordingly, in order to obtain smooth repetitive motion, and as a result, the stress that repeatedly acts on the transmission member 6 and 7vc becomes large. The thermal expansion coefficient of the piezoelectric body 2 is about rr(o~2)XIO/1, but the thermal expansion coefficient of the spring steel material The expansion coefficient rJ (10 to 20) is approximately 02/°C.For example, when a piezoelectric body 2 with a length of 3QII is used as a drive source, both ends of the piezoelectric body 2 are connected to a coupling member 3, a mounting member l, and an rc control member. After fixing with agent, the ambient temperature is 30℃.
When the temperature changes T, the change in the length of the piezoelectric body 2 and the change in the length between the connecting member 3 and the mounting member 1 are calculated. The difference between VC engineering and piezoelectric body 2
A tensile stress acts on the rc compression body, but the piezoelectric body 2 has low strength against the tensile stress, so especially when the temperature rises, the tensile stress 1c causes a crack f'L in the piezoelectric body 2, resulting in peeling failure. Easy oJ! As mentioned above, as the temperature changes, the piezoelectric body 2
The length of the piezoelectric body 2 changes, but the amount of change may be approximately the same as the amount of change in length due to dimensional distortion caused when the piezoelectric body 2 is driven. In such a case, the tip position of the wire 9 may shift depending on the change in the length of the piezoelectric body 2, and the wire 9 may no longer impact the surface of the paper when driven, or conversely, the vc% wire 9 may be reduced when not driven. is paper 1CIl
＋If you touch it, you will not be able to print normally 0Also, depending on the change in the length of the piezoelectric body 2V] Member 4 machining 5v
cf, and the C crack is transmitted to the transmission member 6 and 79, and even when it is not driven, the same stress of the same magnitude as when it is driven acts on the transmission member 6 and 7, which is generated when it is driven. /) The stress is 91
When folded, the fatigue limit is exceeded and breakage occurs, resulting in a minor cause of rc.

す工程を含んでいる。An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a printing element and a method for manufacturing the same, which completely prevents breakage of the transmission member during operation, peeling-off of the piezoelectric material, and displacement of the tip of the wire. 60 Element a of the present invention is composed of a piezoelectric body that generates dimensional distortion in response to applied voltage, and a metal material having one end fixed to the piezoelectric body and having substantially the same coefficient of thermal expansion as the piezoelectric body. The other end of each piezoelectric body is connected to the mounting member via a plate-like member, and the piezoelectric body is connected to the plate-like member at the other end. given through/)
In response to the dimensional distortion, an angular displacement of the first and second movable members opening in opposite directions is caused, and one end of the first and second movable members (6) and (7) are connected to the first part. The first and second transmission members of the metal plate are fixed to the second movable member, and the other ends of the second and second transmission members are completely fixed, and the transmission is carried out through both of them. The present invention further comprises a third movable member which rotates in response to the second angular displacement of the first machine and which has one end fixed and which imparts a printing operation to the thin rod-shaped wire. The manufacturing method includes welding one end of the first and second transmission members of the metal plate to the first and second movable members made of low expansion steel, and the second transmission member described in Fffff. After each other end of the second transmission member is melted into the third movable member made of low expansion steel, the method includes a step of applying heat treatment at a predetermined temperature for a predetermined period of time.

As mentioned above, the transmission members 6L and 7iMA steel are formed, and both ends of these are attached to predetermined locations of the movable member 4°5 and 8.
Brazing rb with a brazing filler metal whose melting temperature is set within the range of 20 to 900°C. After that, heat treatment is performed at 480° C. for 3 hours. The movable parts 4 and 5 are brazed in advance at 82.
It has been solution treated at 0'C and has a fatigue limit of approximately 4 Q kg/nyg2 when cooled at room temperature, but brazing is age hardened by subsequent heat treatment and has a fatigue limit of approximately 80 kg/nyg2. Therefore, the fatigue limit of the melted part of the transmission member 6 and machining 7 does not deteriorate after melting and does not reach VcH as in the conventional case, but the fatigue limit of the age-hardened RC exhaust by heat treatment 1c is about twice that of the conventional one. It is possible to prevent breakage and breakage during operation.
