A plate bending machine for performing precise bending operations includes a machine pedestal having two opposite side sections, a guide member provided at each side section of the machine pedestal, and a vertically movable guide post supported by the guide members. A lower bending tool is supported by the machine pedestal and an upper table has two side sections, each supported by the guide posts. An upper bending tool is supported by the upper table and is adapted to move vertically with the upper table to operate in cooperation with the lower bending tool. An eccentric shaft is supported in a freely rotatable manner on the machine pedestal and has an eccentric section with which the guide post is engaged at its lower section, wherein there is play between the guidepost and the eccentric section. A play removing device is mounted on the machine pedestal, for removing the play between the guide post and the eccentric section.

To detect a line position described on a surface by a simple structure, the line position detecting apparatus comprises a light beam generator including a laser diode, a collimator, a prism, and a mirror; a motor for rotating a laser beam to describe a circular locus on the surface; an encoder for detecting a laser beam angular position; a photosensor for detecting a laser beam reflected from the surface; and a calculator for detecting an angular position at which light beam intensity changes due to the presence of the line at at least one point of intersection between the line and the circular locus and for calculating the point indicated by x-y coordinates on the basis of the diameter of the circular locus and the detected angular position of a line to be detected.
