PURPOSE: To smoothly move a product from a preparation station to a measuring table without damaging it by adjusting inclination and height of a movable table frame having a work plate.

CONSTITUTION: Two support surfaces 3 are provided on a work plate 2 on top of a movable frame 1 in the form of a carriage. The work plate 2 is placed on hinge type supports 7, and the supports 7 can be vertically driven separately from each other by servo motors with slide parts 4. A signal generated by a contactless switch on the support part 3 is processed by a computer 5 with an electronic control part 6 to be supplied to a step motor. A height position and inclination of the work plate 2 can thus be matched to those of a preparation plate and a measuring table, thereby achieving accurate movement without risk of damaging a product by alignment of the planes.
