報）。2. Description of the Related Art Conventionally, during a chemical strengthening process for chemically strengthening a glass substrate, a chemical strengthening jig for holding the glass substrate is a corrugated thin plate that supports the left and right sides of the glass substrate. There is known a metal jig that includes a shaft-shaped body that supports the bottom of a glass substrate and vertically supports the glass substrate at three locations (Japanese Patent Laid-Open No. 07-309639).

ある。However, in the metal jig used in the above-mentioned chemical strengthening process, the glass jig or the like is conveyed or vibrated during the transportation while holding (set) the glass substrate or the chemical strengthening process. Among them, due to the difference in the amount of thermal deformation caused by the difference in the coefficient of thermal expansion between the metal jig and the glass substrate in the preheating / slow cooling process, a load is applied from the jig to the edge portion of the glass substrate to cause cracking or chipping. May occur.

がある。That is, since the conventional metal jig has no cushioning material at the bottom of the jig for supporting the glass substrate, the glass substrate has a structure in which the glass substrate is likely to be directly impacted, and a wave supporting the left and right sides of the glass substrate is used. Since the plate-shaped thin plate is fixed to the jig body, the glass substrate receives a load from the metal jig due to the difference in the amount of thermal deformation caused by the difference in the coefficient of thermal expansion between the glass substrate and the metal jig. Furthermore, the difference in the thermal conductivity and the specific heat due to the difference in material between the glass substrate and the metal jig may cause an extreme temperature difference between the two, which may cause thermal cracking in the glass substrate.

Jigs have problems with abrasion resistance, and carbon fiber jigs have problems with oxidation resistance and cannot be used.

That is, (1) impact caused by the corrugated plate member 7 when the glass plate 5 is set in the glass plate holder 1, and (2) heat caused by a difference in coefficient of thermal expansion between the glass plate 5 and the corrugated plate member 7. The load received from the corrugated plate member 7 due to the difference in the amount of deformation, and (3) the heat due to the extreme temperature difference between the glass plate 5 and the corrugated plate member 7 caused by the difference in the thermal conductivity and the specific heat. It is a crack.

ある。In the present embodiment, in order to prevent the above (1), the surface of the corrugated plate member 7 is covered with the stainless woven cloth 10. Thereby, when the glass plate 5 is set in the glass plate holder 1, chipping, microcracks, and the like that occur at the edge portion of the glass plate 5 are prevented, and the temperature at the contact portion between the glass plate 5 and the corrugated plate-shaped member 7 is prevented. It is possible to prevent thermal cracking due to the difference. Further, the woven cloth 10 made of stainless steel is excellent in abrasion resistance, heat resistance, oxidation resistance, and thermal conductivity, and is suitable as a cushioning material in the contact portion with the glass plate 5.

高くなる。Since the glass plate 5 is used as a platen glass for a copying machine, its edge portion is usually thread-chamfered (C-cut). Conventionally, the entire corrugated width of the thread is chamfered. I was in contact with 7. However, if the processing accuracy of the thread chamfering width is poor, a part of the thread chamfering width comes into line contact with the corrugated plate-like member 7, and when the glass plate 5 is set in the glass plate holder 1, The edge of the glass plate 5 is likely to be chipped or microcracked due to the impact received from the strip-shaped member 7. Furthermore, when heat is applied to the glass plate 5, the rate of occurrence of thermal cracks and chips increases.

れや欠けを防止することができる。Therefore, the angle θ (FIG. 2) of the crests of the corrugated plate member 7 is preferably 90 degrees so as to support the glass plate 5 over the entire thread chamfering width. Even if the thread chamfering width is unevenly processed, since the stainless steel woven cloth 10 contacts the corrugated plate-like member 7, the stainless woven cloth 10 is deformed to absorb the unevenness of the thread chamfered width. However, the glass plate 5 can be prevented from cracking or chipping.

The pair of first support portions 3 supporting both end portions of the glass plate 5 are
Slide horizontally. In the present embodiment, the glass plate 5 is supported at least at one end on each side in the horizontal direction with respect to the glass plate 5 and the lower part in consideration of the vibration during transportation which is received from the glass plate holder 1 in the actual manufacturing process. 2 points in total
Do in points. However, basically, the glass plate 5 is supported at three points, and the fourth point is merely an auxiliary.

0 −7 , and SUS304 used for the corrugated plate member 7 is 173 × 10 −7. Therefore , for example, when heat exceeding 400 ° C. is applied during the chemical strengthening step, the glass plate 5 and the corrugated plate member 7 are It is difficult to perfectly match the edge portion of the glass plate 5 and the position of the slope of the corrugated plate member 7 at the four support points supporting the glass plate 5 due to the difference in the amount of thermal deformation caused by the difference in the coefficient of thermal expansion of the glass plate 5. Becomes

When a force is applied to the support points at both ends of the, the slide points are slid outward in the horizontal direction.

Further, even when the glass plate holder 1 itself is used for a long period of time, the amount of thermal deformation of the glass plate holder 1 itself is small, and the relative positions of the four supporting points of the glass plate 5 do not change. Therefore, maintenance of the glass plate holder 1 is easy.

ある。Further, in order to prevent the above (3), as described above, the woven cloth 10 made of stainless steel is used at the contact portion with the glass plate 5. That is, it is necessary that the edge portion of the glass plate 5 and the corrugated plate-shaped member 7 do not have a large temperature difference, that is, they are in contact with each other in terms of temperature. Thermal conductivity (kca) of soda lime glass used for the glass plate 5.
