ABSTRACT:
A displacing apparatus includes a moving table provided movably on a guide rail mounted on a fixed base. A guide bar is provided on the fixed base in parallel with the guide rail. The guide bar is formed with a recess. Also provided is a driving roller maintained in contact with the guide bar and driven by a driving source provided on the moving table for moving the moving table. A device is provided on the moving table for generating a contact pressure for maintaining the driving roller in pressure contact with the guide bar at a position on the guide bar opposite to the drive roller. A detector is also provided in relation to the moving table for detecting the position of the moving table. Finally, a device is provided for nullifying the contact pressure. The nullifying device drops the driving roller into the recess of the guide bar to nullify the contact pressure of the drive roller, the drive roller moving on the guide bar.
