Sheet like paper products conveying route switching apparatus

Abstract

A coordinate measuring system is provided having a pair of rotary laser devices vertically spaced from one another with the same rotational axis C. Each rotary laser device radiates fan-shaped laser beams inclined off of the horizontal towards a photosensor device. The photosensor device receives the fan-shaped laser beams to obtain tilt angles α, β against the horizontal plane and then obtains a height of the photosensor device and horizontal distance X from the rotary laser devices to the photosensor device, based on both of the tilt angles. Further, this operation part measures a rotation angle from a reference direction based on time difference generated when the fan-shaped laser beams, mutually-rotating in the reverse direction, are received at the photosensor device located on an unknown point D 2. Coordinates of the unknown point D 2 are calculated based on the rotation angle and the coordinates of at least two known points.
