[Prior Art] 0 For dust-removing objects such as glass substrates used in TFT (thin-film transistor) liquid crystal panels, PDP (plasma display panel), or LCD (liquid crystal display), or sheets such as long paper or film (the following only It is called dust-removing object), and dust is removed by a dust removal device. The dust cleaner included in the dust removing device has a function of ejecting the washing air to the object to be dusted, causing the dust to fly from the object to be dusted, and sucking in the scattered dust together with the washing air. The prior art dust cleaner will be described below in accordance with the drawings. Figure 10 is a perspective view of a prior art eliminator. Figure 11 is a cross-sectional view of a prior art dust cleaner. As shown in Fig. 10, the dust cleaner 10 includes a cleaner body 110 and a slit body 120, and a slit body 120 is provided on the lower side of the cleaner body 110. As shown in Fig. 11, the cleaner body 110 is formed by arranging an air suction chamber 111 (VI), an air ejection chamber 112 (P), and an air suction chamber 113 (V2).

[Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. Fig. 2 is a bottom view of the dust cleaner, Fig. 2 is a bottom view of the dust cleaner, and Fig. 3 is a sectional view of the dust cleaner. The cross-sectional view of the dust cleaner of Fig. 3 is a cross-sectional view of Fig. 2. In addition, there are configurations that are repeated with the prior art, but for the sake of purity, the same symbols are used. As shown in Fig. 1 or 2, the dust cleaner 100 includes a cleaner body 11A, a slit body 120, and a weir 130. A slit body 120 is provided on the lower side of the cleaner body 11A, and a cover 13b is attached to the lower outer side portion of the cleaner body 110. Further, as shown in Fig. 3 to be described later, the cleaner body 11A, the slit body 12A, the cover 13A, and the buffer space 140 covered by the surface of the dust-removing object G are formed. Φ The cleaner body 110 is formed by arranging an air suction chamber (VI), air to 112 (Ρ), and an air suction chamber U3 (V2) as shown in Fig. 3 . The air suction chambers hi, 113 are connected to an air suction pump (not shown), and the air ejection chamber 112 is connected to a blower pump (not shown). The air suction chamber 111, the air ejection chamber 112, and the air suction chamber 113 each include a suction vent hole 114, a discharge vent hole U5, and a suction vent hole U6. The slit body 120 forms a concave surface, a flat surface 122, and a concave surface 123 as opposed to the dust removing object g, and also forms a suction slit 124 in the concave surface 121, and forms a 2146-7269-PF 8 1287472 ejection slit 125 in the plane 122 to form a suction slit in the concave surface 123. 126. The plane 122 is formed in order to make the flow rate of the sprayed washing air constant. Concave surfaces 121, 123 are formed in order to facilitate the inhalation of the washing air. The suction vent 114, the discharge vent 115, and the suction vent 116 of the dust cleaner 1 are each in communication with the suction slit U4, the discharge slit 125, and the suction slit ι26 of the slit body 12. In this embodiment, the crucible 130 has a rectangular tubular body having a mouth-shaped opening. Further, the cymbal 130 has various forms, but may be formed into a buffer space 140 at least between the slit body 12A and the cover 13A. The buffer space 140 is a space formed in a mouth shape between the cleaner body 11 〇, the slit body 12 〇, and the cover 13 。. As shown in Fig. 3, the buffer space 14 is also a space sandwiched by the dust removing object G when the dust cleaner 100 is used. The buffer space 14 communicates with the outside through a gap portion 141 formed between the dust-removed object G and the cover 130. Further, the buffer space 140 is not limited to a space of a mouth as long as it covers at least the space around the slit body 12A. # Next, the method of using the dust cleaner 100 will be described. The dust cleaner 100' ejects the washing air from the discharge slit 125, so that the dust on the surface of the dust-removing object G floats in the space between the dust cleaner 1 and the dust-removed object G. At the same time, the washing air is sucked in by the suction slits 124, 126 before and after the discharge slit 125, and is removed together with the floating dust. Further, the total suction amount of the washing air from the air suction chambers lu, 113 is larger than the amount of the washing air from the air ejection chamber 112. In this dust cleaner, the washing air (simple washing air, air containing ultrasonic waves vibrating at a supersonic frequency, or air containing positive and negative ions) is output. 2146-7269-PF 9 •1287472 This kind of strip air vibrates and has noise problems when it is ejected. In particular, in the case of washing with ultrasonic waves, the noise caused by ultrasonic vibration is remarkable. However, these vibrations reach the cover 130 via the slow contact chamber (10), and the vibration caused by the ultrasonic waves by the cover (10) is attenuated. Further, since the gap portion i4i is a narrow gap, most of the gaps pass through the cover 13 and the noise of the worker is also reduced. The buffer portion 141 is connected to the external space. However, since the suction amount of the washing process is larger than the discharge amount in the cover 13 ,, the buffer space (10) is kept low relative to the outer space. The gap portion 141 is occluded from the external space to the internal buffer space. This is illustrated with reference to the figure. 4, 5, and 6 are explanatory views each illustrating a flow of washing air of the dust cleaner. In the substrate conveyance direction, as shown in FIG. 4, the knee-washing air from the discharge slit 125 is sucked by the front and rear suction slits 124, 126. Further, air is also introduced from the buffer space 14A or the gap portion 141, and is sucked by the suction slits 124, 126. Therefore, air does not flow from the buffer space 140 to the outside. Further, due to the large amount of suction, the buffer space 14 〇 is sufficiently low. Next, in the lateral direction of the discharge slit 125, as shown in Fig. 5, a portion of the washing air emerging from the discharge slit 125 flows in the lateral direction, and air flows from the outer space to the low pressure through the gap portion 141. When the buffer space is 14 inches, air collides in the buffer space 14〇, and the washing air does not flow out due to flowing into the buffer space 14〇. The receiver is sucked in the lateral direction of the slits 124 and 126 by the suction slits 124 and 126 as shown in Fig. 6 . Further, air is also introduced from the buffer space 14A or the gap portion 141, and is sucked by the suction slits 124, 126. Therefore, the washing air does not flow out from the gap portion 2146-7269-PF 10 • 1287472 141. Then, the air in the gap portion 141 flows into the cover 130 from the external space at any position. Therefore, the dust scattered by the washing air does not escape from the buffer space 140, and the dust can be sucked in by the suction slits 12 4 and 12 6 . Thus, since the buffer space 140 can be formed by the cover 130, the noise can be suppressed and the dust removing performance can be improved with a simple configuration.

Figure 7 is a cross-sectional view of a dust cleaner of another form. Incidentally, the same reference numerals are given to the configurations overlapping with the above-described configurations, and the overlapping description will be omitted. In the present embodiment, the dust cleaner 100 shown in Fig. 2 is disposed on the front and back sides of the dust-removing object G in two groups. In this configuration, dust can be removed on both sides of the surface of the dust-removed object G, and for the above reasons, noise can be simultaneously reduced and dust removal performance can be improved. Next, another form will be described with reference to the drawings. Figure 8 is a cross-sectional view of a dust eliminator of another form. Incidentally, the same reference numerals are given to the configurations overlapping with the above-described configurations, and the overlapping description will be omitted. In this embodiment, the shape shown in FIG. 3 is almost the same, but the ejection slit 125 of the slit body 120 shown in FIG. 3 is formed in a substantially vertical direction with respect to the dust-removed object G, but is shown in FIG. In the form, the discharge slit 125' of the slit body 120 is inclined so that the discharge direction and the substrate conveyance direction a are opposite directions. In this configuration, there is an advantage that the flow of the washing air is stabilized when the dust removing object G enters the dust cleaner 100. When the dust is removed by the dust cleaner 100, the flow rate from the air ejection chamber 112 (P) to the air suction chamber 111 (Vl) increases, and part of the air 2146-7269-PF 11 1287472 ♦ flows from the outside air collision In the buffer space (10), the washing air does not leak out from the cover, so that the surface of the dust-removing object G can be dusted, and for the above reasons, the noise can be simultaneously reduced and the dust removing performance can be improved. Then, the other side is explained by the side. Figure 9 is a cross-sectional view of a dust cleaner of another form. In this embodiment, as shown in FIG. 8, the discharge slits 125 in which the slit bodies 120 are disposed facing each other on the front and back sides of the dust-removing object G are inclined in the discharge direction and the substrate conveyance direction & Dust cleaner 1 〇〇. In this configuration, dust can be removed on both sides of the surface of the dust-removing object G, and for the above reasons, noise can be simultaneously reduced and dust removal performance can be improved. Further, the present invention also has various modifications. For example, in FIG. 7 and FIG. 9, the dust-removing object G is conveyed on the conveyance roller or the like which is not shown in the figure, but in this case, the air flowing from the top of the dust-removing object G (the upper dust-removing device 100) flows. The suction force on the upper side utilizing the effect of the instrument is generated, and the suction of the lower side of the venturi effect is generated by the air flowing under the dust-removing object G (the dust removing device 100 on the lower side), but It is adjusted to become a balance of the venturi effect which increases the suction force of the lower side, and it is also possible to carry out the stable dust removal object G. In this case, the suction pressure (intake amount) of the dust removing device 1 on the lower side and the suction pressure (intake amount) of the dust removing device 100 on the upper side are made equal, and the dust removing device 100 from the lower side is made The discharge pressure (discharge amount) is larger than the discharge pressure (discharge amount) of the dust collector 100 on the upper side, and the dust removal device 1 on the lower side uses the Venturi tube effect 2146-7269-PF 12 1287472. The suction force is set to be larger than the suction force of the dust removing device 100 on the upper side by the venturi effect, so that the force of the substrate to be pressed against the conveyance roller (not shown) may be applied. In addition, the discharge pressure (discharge amount) from the dust removing device 100 on the lower side and the discharge pressure (discharge amount) from the dust removing device 100 on the upper side are made equal, and the lower side dust removing device 100 is placed on the lower side. The suction pressure (inhalation amount) is larger than the suction pressure (intake amount) of the upper dust removing device 100, and the suction force of the lower dust removing device 100 by the venturi effect is set to be higher than that of the upper dust removing device 100 by the venturi effect. The suction force is large, so that the assignment of 0 and the force of pressing the substrate to the conveyance roller is also possible. In addition, the interval from the lower side of the dust removing device 1 to the back surface of the dust removing target G is adjusted to be smaller than the interval from the dust removing device 1A on the upper side to the surface of the dust removing target G, and the lower side is provided. The suction function of the dust removing device 100 by the venturi effect is set to be larger than the suction force of the upper side dust removing device 1 by the venturi effect, so that the force for pressing the substrate against the conveying roller can be imparted. In such a dust removing device, it is also possible to further improve the usability. [Simple description of the drawing] Figure 1 is a three-dimensional appearance of the dust cleaner.
