Abstract

PURPOSE:To facilitate handling by arranging plural engagement parts having engagement step parts fitted to a part of the outer periphery of a glass disk and a part of a piece surface near the outer periphery in the storage parts of respective cases of a pair of the cases which are provided so that they can freely be opened/closed. CONSTITUTION:The engagement step part 5 engaged with a part of the outer peripheral part of the glass disk 4 is provided for the storage part 2 of the rectangular first case 3, the engagement step part 5 of plural engagement bodies 6 are engaged to a part of the outer peripheral part of the glass disk 4. Then the glass disk 4 is positioned. An engagement part 6' provided with the engagement step part 5' similar to the first case 3 is provided for a second case 8 which is provided so that it can freely be opened/closed to the first case 3 through a hinge 7 and the glass disk 4 is positioned on either side of the first case 3 or the second case 8, whereby it is stored. If either the surface or the back of the glass disk 4 is to be exposed, the surface to be exposed opens the first case 3 or the second case 8, which is exposed. Thus, the surface to be exposed is exposed with the glass disk 4 in a positioned state. Thus, either case can be opened/closed and handling becomes facile.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is used for automatically conveying, transporting, and storing glass disks in a very clean environment in a manutaring facility in a photonic manufacturing facility. This invention relates to a glass disk storage cartridge.

Conventional technology In recent years, cartridges for storing glass discs that are handled in extremely clean environments have been developed to improve the storage capacity of glass discs, increase the ease of handling glass discs, and extremely suppress dust generation. There is an increasing demand to do so.

A conventional glass disk storage cartridge of this type will be explained with reference to FIG. As shown in the figure, a hinge 14 is inserted into a rectangular lower case 13 provided with a frame 12 so as to form a storage section 11 inside.

The upper case 15 is provided so as to be openable and closable, and the side walls of the lower case 713 and the upper case 715 are provided with opening/closing holes 16, respectively, to enable automatic opening/closing by an automatic machine or the like.

The storage portion 11 of the lower case 713 is provided with a pair of receiving portions 19 provided with an engaging portion 18 that engages with a part of the circular arc portion of the outer periphery of the glass disk 17 to be stored. The cartridge was configured to receive one side of the glass disc 17, position the glass disc 17 using engaging portions 18 formed at four locations, and cover and house the glass disc 17 with an upper case 715.

Problems to be Solved by the Invention In such a conventional glass disk storage cartridge, the glass disk 17 is only positioned in four directions by the engaging portion 18, and care must be taken in the vertical direction when handling such as transportation. Must be. In addition, when handling such as transportation, the surface coated with the photosensitive agent should be placed so that it faces the surface of the lower plate of the upper and lower cases 13, so when performing operations such as exposure and development, the glass disk 17 should be removed. It is necessary to flip the top and bottom sides. Furthermore, the upper case 16 does not have sufficient strength due to its structure, so there is a problem in that it interferes with the frame 12 when opening and closing, and there is a possibility of dust generation.

The present invention solves the above problems, and provides a glass disk storage cartridge that does not require a glass disk reversing device in the exposure, development, etc. equipment, is extremely easy to handle, and has low dust generation. The purpose is to

Means for Solving the Problems In order to achieve the above object, the glass disc storage cartridge of the present invention should engage a part of the outer periphery of the glass disc and a part of one side near the outer periphery of the glass disc. A plurality of engaging bodies each having an engaging stepped portion are arranged in a housing portion of each case of a pair of cases that are provided so as to be openable and closable so as to position and hold the glass disc.

Function In the glass disk storage cartridge of the present invention, the glass disk can be positioned on either side of the case due to the above-described configuration, so when it is desired to make either the front or back surface of the glass disk The surface to be exposed can be opened by opening the case on the exposed side, eliminating the need to directly invert the glass disk, making it easy to handle, less dusty, and cheaper to manufacture.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

As shown in the figure, a rectangular first cane 3 has a frame 1 around it and a storage part 2 inside, and a part of the outer periphery of the glass disc 4 and the outer periphery of the glass disc 4 are placed in the storage part 2 of the first canine 3. It has an engagement step portion 6 that engages with a part of one side nearby, and this engagement step portion 6
The depth of the stepped portion is approximately equal to the thickness of the glass disk 4, and the engaging body 6, which is formed to have the same height as the frame 1, is inserted into the storage section 2 from the inside of the frame 1. A plurality of engagement steps 5 of the plurality of engagement bodies 6 are engaged with a part of the outer periphery of the glass disk 4 to position the glass disk 4 from side to side and front to back. There is.

On the other hand, the second case 8, which is provided on the first case 73 via the hinge 7 so as to be openable and closable, is provided with an engagement body 6' having an engagement step 6' similar to that of the first case 3. A double opening/closing hole 9 is provided in the side wall of the second cane 78 to enable automatic opening and closing by an automatic machine or the like, and the glass disk 4 can be positioned on either side of the first cane 3 or the second cane 8. By bringing the first cane 73 and the second cane 8 together and closing them via the hinge 7, the glass disc 4 is held between the engaging bodies 6 and 6', and the vertical movement of the glass disc 4 is also restricted. The cartridge is configured to accommodate the plate 4.

In the above configuration, when it is desired to expose either the front surface or the back surface of the glass disk 40, it is possible to open the first case 3 or the second case 8 on the side where the surface to be exposed is exposed, for example, the second case 8. When the case 78 is opened, the surface of the glass disk 4 that is desired to be exposed is exposed while being positioned and held by the engaging body 6 on the first case 73 side. In addition, when transporting, etc., the first case 3 and the second case 8
When the glass discs 4 are brought together and closed, the glass disc 4 is connected to the engagement step 6 of the engagement body 6 provided on the first case 73 and the engagement step 5' of the engagement body 6' provided on the second case 8. The glass disc 4 is positioned and clamped by both the engagement steps 6 and 6', and the horizontal and vertical movements of the glass disc 4 are regulated, and the glass disc 4 is connected to the cartridge. It is stored in a securely held state.

As described above, according to this embodiment, the engaging body 6 for positioning
and 6' allow the glass disk 4 to be positioned in all directions and in the vertical direction, making handling of the glass disk 4 extremely easy. Each of cases 73 and 8 has the functions of an upper case and a lower case of a conventional glass disc storage cartridge, so that it can be opened and closed from either case 3 or 8, allowing exposure. There is no need to provide a reversing device for the glass disk 4 in a developing device or the like.

In addition, dust generation during opening and closing can be suppressed as much as possible.

Effects of the Invention According to the present invention, by positioning the glass disk in all directions and in the vertical direction using the positioning engaging body provided in each case, the handling of the glass disk during transportation is much easier compared to conventional methods. becomes easier. In addition, each case is configured to have the functions of both a conventional case top plate and a case bottom plate, so each case can be opened and closed from either side, minimizing dust generation when opening and closing. We can provide a glass disc storage cartridge.
