PURPOSE: A glass substrate scriber Is provided to confirm position movement value of a linear motor in a vertical guider and to conform torque value applied on a wheel in real time. CONSTITUTION: A glass substrate scriber comprises a vertical guider (10); a linear motor (20); a scale (30); a main slider (40), a sub slider (50); a wheel holder (60); a load cell (70); and a control section. The linear motor is installed in an upper part of the vertical guider. The linear motor is installed in the upper part of the vertical guider. The scale generates a moved distant signal corresponding to the movement of the linear motor. The main slider slides the vertical guider being connected to the linear motor. The sub slider is combined to the main slider allowing sliding. The wheel holder is installed in a sub slider and supports the wheel (61). The load cell is installed in one among a main slider or a sub slider and generates a corresponding pressure signal pressurizing the other one among the main slider or a sub slider. The control section controls the linear motor being connected to a moving distance signal and the pressure signal.
