Abstract

An apparatus for finely actuating a glass electrode or the like tool includes a movable portion adapted to be vertically displaced with the aid of a vertical actuating mechanism. A Y-coordinate slider is mounted on the movable portion to slide in the Y-coordinate direction and a X-cordinate slider is in turn mounted on the Y-coordinate slider to slide in the X-coordinate direction. A Y-coordinate thrusting rod is provided in the movable portion to thrust a Y-coordinate lever rod disposed between the Y-coordinate thrusting rod and the Y-coordinate slider, while a X-coordinate thrusting rod is likewise provided in the movable portion to thrust a X-coordinate lever rod disposed between the X-coordinate thrusting rod and the Y-coordinate slider. This enables a lever ratio to be reduced to a fraction of the ratio. Two return springs are provided so as to allow both the Y-coordinate slider and X-coordinate slider to resume their original position. One of them is resiliently bridged between the movable portion and the Y-coordinate slider and the other one is resiliently bridged between the Y-coordinate slider and the X-coordinate slider.

An apparatus for adjusting the position of an instrument for the purpose of acting on a cell, said apparatus comprising:

a casing having at least one surface open;
movable portion means mounted in said casing and being provided for moving in the vertical direction;
first adjustment means for adjusting the vertical position of the movable portion means;
Y-coordinate actuating slider means mounted on said movable portion means for freely sliding along a first lateral direction perpendicular to the vertical direction;
second adjustment means for adjusting the position of the Y-coordinate actuating slider means along the first lateral direction;
X-coordinate actuating slider means mounted on said Y-coordinate actuating slider means for freely sliding along a second lateral direction perpendicular to both the first lateral direction and to the vertical direction;
third adjustment means for adjusting the position of the X-coordinate actuating slider means along the second lateral direction;
X-coordinate rough actuating slider means mounted on said X-coordinate actuating slider means for freely sliding along the second lateral direction;
forth adjustment means for adjusting the position of the X-coordinate rough actuating slider means along the second lateral direction;
Y-coordinate rough actuating slider means mounted on said X-coordinate rough actuating slider means for freely sliding along the first lateral direction;
and
fifth adjustment means for adjusting the position of the Y-coordinate rough actuating slider means along the first lateral direction.
