2 and 3, a substrate floating apparatus 100 according to a preferred exemplary embodiment of the present invention includes a plurality of vertical holes 102 and a plurality of inclined holes 104, (110). The vertical holes 102 and the inclined holes 104 are formed through the surface of the hollow main body 110 and communicate with a fluid inlet (not shown) provided at either end of the main body 110. It will be appreciated by those skilled in the art that fluid inlets may receive fluid from a fluid source not shown. That is, the fluid source can supply compressed air at a predetermined pressure, for example, through the fluid inlet of the main body 110 to the inside of the main body 110, and the fluid introduced through the fluid inlet is supplied to the vertical holes 102, And is ejected through the holes 104 to the surface of the substrate 3 at a predetermined pressure. The vertical holes 102 and the inclined holes 104 are formed in an appropriate number to prevent contact between the substrate 3 and the surface of the main body 110 and are ejected through the holes 102 and 104 The fluid preferably has a pressure sufficient to prevent contact with the substrate and the body 110.

The body 110 of the substrate floating apparatus 100 shown in Fig. 3 shows the formation of the vertical holes 102 and the tapered holes 104 formed at the upper end of the cylindrical body, As will be described in greater detail, vertical holes 102 and tapered holes 104 are distributed over an angle of approximately half or more of the circular cross-section of body 110 (approximately 200 degrees).

2, for example, the base material 3 entering from the left side of the main body 110 is separated from the main body 110 by the vertical and inclined holes 102 (104) provided in the main body 110 And can be shifted to the right side of the main body 110 and can be moved. 3, the substrate floating apparatus 100 according to the preferred embodiment of the present invention includes vertical holes (not shown) provided in the main body 110 so as to correspond to most positions in the widthwise center of the substrate 3 102 to float the base material 3 from the main body 110. On the other hand, the inclined holes 104 provided at both ends of the main body 110 at positions corresponding to both side edges of the base material 3 are configured to inject fluid toward the widthwise center of the base material 3. The inclined holes 104 are formed in such a manner that the fluid ejected by the vertical holes 102 is discharged to the space formed between the both side edges of the substrate 3 and the main body 110, And has a function of preventing the floating force from being deteriorated and influencing the travel of the base material 3. [ The holes 102 and 104 formed on the surface of the main body 110 have a diameter of 1 mm or less and a diameter of 1 cm ² It is preferable that one or more of them are formed. This is because this distribution of the holes 102 and 104 can minimize the vibrations of the substrate 3 that may occur during fluid injection by distributing the force within the contact area of the substrate 3 and the body 110 .

2, a substrate floating apparatus 100 according to another preferred exemplary embodiment of the present invention includes a lower portion of a body 110, that is, an auxiliary for supplying additional fluid to an input portion 106 and an output portion 108, And further includes a fluid supply member 120. When the holes 102 and 104 are provided in the main body 110 having a circular cross section, the lifting force of the base material 3 depends on the air pressure at a specific portion, So as to increase the lifting force of the base material 3 at the input portion 106 and the output portion 108 where the area is widened and the pressure drop occurs structurally. That is, the auxiliary fluid supply member 120 can prevent pressure drop due to the above-described reason by forming the input section 106 and the output section 108 in a linear section having a constant length. Therefore, the substrate floating apparatus 100 according to the present embodiment can be lifted by the fluid ejected through the auxiliary holes 122 formed in the auxiliary fluid supply member 120, so that the input unit 106 and the output unit 108 The substrate 3 can be stably lifted.

It is preferable that the side plates 130 are installed so as to be spaced apart from the ends of both side edges of the substrate 3 by approximately 1 mm. The side plate 130 is installed to be movable in the longitudinal direction of the main body 110. This is to adjust the position of the side plate 130 to match the width of the substrate 3 used in the apparatus 100. Other modifications of the side plate 130 will be described later.

In other words, the fluid ejected from the inclined holes 104 has a function of blocking the fluid that is ejected through the vertical holes 102 and moves in both ends of the main body 110. Each of the inclined holes 104 is formed by a sloped funnel-shaped inclined ejection portion 104a having a long side portion and a short side portion formed by inclined entrance from the outer surface of the hole plate 210 to the inner surface, And an inclined penetration portion 104b penetrating through the hole plate 210 in an inclined manner. The diameter of the inclined penetrating portion 104b is approximately 1.0 mm, and the interval between adjacent inclined penetrating portions 104b is approximately 3.03 mm.
