Abstract
A processing apparatus includes a first imaging unit over a chuck table that images a back surface side of a workpiece, a second imaging unit under the chuck table that images a front surface side of the workpiece in a region corresponding to a region imaged by the first imaging unit, and a control part that inverts, in a predetermined direction, either a first image obtained by imaging of a processed groove on the back surface side by the first imaging unit or a second image obtained by imaging of the processed groove on the front surface side by the second imaging unit in such a manner that orientations of the first and second images correspond with each other, and that causes a display device to display both the processed groove in the first image and the processed groove in the second image that are superimposed.
