I recently removed the cup in my Diner to clean the play field. The cup is screwed to a 90 degree metal bracket that is held by 4 screws onto the back wall of the play field. I rotated the play field up, lifted it out of the hinge mounts and then dropped it on top of the mounts so it sat a little higher and farther forward. With a little mirror I could guide a stubby screwdriver into the 4 screws holding the bracket to the play field and get them out to remove the cup/bracket assembly. Same process to get it back in.
