Abstract

PURPOSE:To miniaturize the title device to prevent vibration by supporting an arm by the slide unit attached to an arm holder. CONSTITUTION:In an X-ray inspection device, an arm 2 and an arm holder 1 are supported by a slide unit 6 and the slide unit 6 slides in such a state that the rail 5 arranged along the arm 2 and the block 4 provided to the arm holder 1 are fitted each other because a plurality of the balls (not shown in a drawing) arranged to the contact surface with the rail 5 of the block 4 allow the rail to slide. By this constitution, multi-point dispersion support becomes possible by a plurality of the balls between the block 4 and the rail 5 and, therefore, surface pressure can be improved and safety is enhanced. Since highly accurate smooth slide operation becomes possible, the vibration of the device can be suppressed to the min. Since it is unnecessary to consider surface pressure, the arm holder 1 becomes lightweight and compact and the device can be miniaturized as a whole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing an arm portion of an X-ray inspection apparatus according to an embodiment, and FIG. 2 is a sectional view of an arm holder 1. As shown in the figure, this X-ray inspection apparatus supports an arm 2 and an arm holder 1 using a slide unit 6. The slide unit 6 has a structure in which a rail 5 arranged along the arm 2 and a block 4 provided in the arm holder 1 are fitted and slide. This is because a plurality of balls (not shown) arranged on the contact surface of the block 4 with the rail 5 slide the rail.
