Document Type and Number:
Japanese Patent JPH0519470
Kind Code:
B2
Abstract:
PURPOSE:To form a small low cost mechanical amplifying mechanism showing a large amplifying ratio, by providing a base fixing and supporting one end of an electrostriction or piezoelectric element in the extensible direction thereof, a lever arm as a displacement amplifying means connecting the other end of the electrostriction or piezoelectric element to the base and a beam as a displacement amplifying means supported so as to be held between the lever arm and the base. CONSTITUTION:One end of an electrostriction or piezoelectric element 1 in the extensible direction thereof is attached to a base 2 and a lever arm 4 is provided to the other end thereof through a means 3 transmitting the extensible operation of the electrostriction or piezoelectric element 1. Further, the lever arm 4 and the base 2 are connected to another transmission means 3. A beam 5 is connected to the leading end of the lever arm 4 and the other end of the beam 5 is located so as to be fixed to the base 2. A printing needle 6 as an output terminal is provided to the central part of the beam 5 and an adjusting screw 7 for adjusting the initial displacement of the beam 5 from the base 2 and functioning as a back stopper is privided to the rear part of the printing needle 6.
