である。Conventionally, as shown in Fig. 5, an article conveyance device using a static pressure gas bearing has an air supply system that forms an m path (2) over almost the entire length of the slide table (1) in the longitudinal direction. And this air supply passage (
A large number of air supply holes (3) are formed at appropriate intervals to branch out from 2) and open on the surface of the slide table (1), and compressed air generated by a compressor or the like is transferred to an air hose (not shown). When the compressed air is supplied to the air supply f circuit (2) through the air supply passage (2), it passes through each air supply hole (3) and is ejected onto the surface of the slide table (1). ) and the conveyed object (5) placed on this pallet (4) is loaded without contact. In this state, use an appropriate drive device such as a ball screw or near motor (
The pallet (4) is reciprocated by a pallet (not shown) to convey the object (5) on the pallet (4).

テナンスが面倒にならざるを得なかった。However, in the above-mentioned article conveyance device, no matter where the pallet (4) moves, the pallet (4) and the conveyed object (5
), compressed air must be released from the air supply holes (3) over the entire surface of the slide table (1). As a result, a large amount of compressed air leaks from the air supply hole (3) that is not facing the pallet (4) and is emitted in large quantities, which increases the amount of compressed air consumed and increases the running cost. There was a problem in that the internal pressure in the passage (2) also became low and the load capacity of the bearing also decreased. In order to prevent this, the diameter of the air supply hole (3) is made as small as possible, but the air supply hole (3) becomes clogged with dust and oil, which tends to cause malfunction and make maintenance difficult.
