PURPOSE:To make the title reader keep a moving amount needed for a filter changing to obtain a high speed driving, miniaturization and to maintain a high-precision position by using a thing that a piezo-electric body and a displacement enlargement mechanism for enlarging the displacement of the piezo-electric body are combined and attaching a color filter to a part where the greatest displacement can be obtained. CONSTITUTION:The displacement enlargement mechanism is constituted of the piezo-electric body 1, an arm 2 to enlarge the displacement of the piezo-electric body 1 and the equilateral displacement enlargement mechanism 3 of an isosceles triangle whose both end are pressed to obtain an enlargement displacement at a center part by the displacement of the arm 2. The piezo-electric body 1 is extended according to a voltage size by the impressing of the voltage, and the displacement is enlarged by the pair of arm 2 whose one end is connected with the piezo-electric body 1. The arm 2 is connected with the equilateral displacement enlargement mechanism 3 of the isosceles triangle at another end which is not connected with the piezo-electric body 1 so as to transfer the displacement to both end. A great enlargement displacement can be obtained by an angle changing caused by the displacement enlargement mechanism 3'bend. Thus, the moving amount of the color filter can be thoroughly secured and the miniaturization, the high speed driving, and the high-precision can be obtained.

PURPOSE:To prolong the lifetime of a displacement detecting means and facilitate the mounting of a piezoelectric displacement elements into one integrated laminated pizoelectric displacement element by penetrating them with a bolt in the direction of the lamination and attaching a displacement sensor at an axial part of said bolt. CONSTITUTION:A piezoelectric element 1 is an annular one comprising electrodes consisting of a metallic material such as Ag which are formed on both sides of the element 1 and such elements 1 are laminated with an annular voltage applying electrode plate 2 between them. A recess 10 is formed in the longitudinal direction of an axial part of a bolt 9 and a displacement sensor 11, for example, a distortion gauge is bonded to the recess 10 with an adhesive. A lead wire 12 of the displacement sensor 11 is led out to the outside through a groove 13 arranged around an insulator plate 7a. Output signals of the displacement sensor 11 sent through the lead wire 12 are fed back to a drive circuit of a piezoelectric displacing element through a detection circuit and hysteresis of a displaced quantity of the piezoelectric displacing element is removed.
