Background art

[0002] [First Conventional Example]

Optical devices are used in a wide range of communication equipment such as optical transmission equipment as well as consumer equipment such as video cameras and electronic still cameras. The use of optical devices will expand with the spread of new optical devices such as blue laser diodes in the future. Seem.

Regarding the invention of a packaging case that accommodates optical elements such as an optical low-pass filter, a wave plate, and a birefringent plate, which are types of optical devices, the means is disclosed in Japanese Patent Laid-Open No. 2001-2167, Japanese Patent Laid-Open No. 2002-370780, and the like. It is disclosed. Further, regarding the invention of a translucent member case that accommodates a translucent member made of glass, resin, silicon, or the like used for protection of a semiconductor laser element or the like, it is disclosed in JP-A-2002-59989. Yes.

If dust, dust, or the like adheres to the main surface of an optical device, its performance is greatly degraded, so manufacturing and packaging are generally performed in a clean room. It is necessary to use materials that do not generate dust, dust, etc. in the packaging case for optical devices. Also recently, recycling Therefore, a packaging case for optical devices that can be used repeatedly simply by replacing some parts is desired.

FIG. 35 and FIG. 36 are a cross-sectional view of a translucent member case disclosed in Japanese Patent Application Laid-Open No. 2002-59989 and a plan view of a frame member used therefor. The translucent member case includes a frame member 11, a bottom member 12, a lid member 13 and an adhesive sheet 14, as shown in the cross-sectional view of FIG. As shown in the plan view of FIG. 36, the frame member 11 has through-holes 17 for accommodating the translucent member 15 arranged vertically and horizontally, and faces the one opening of the through-hole 17 so that the bottom member 12 As a result of combining these together, a large number of recesses for accommodating the translucent member 15 are formed. When the translucent member 15 is inserted into the concave portion, it is bonded and fixed to the adhesive sheet 14 attached to the upper surface of the bottom member 12. A case 16 for translucent member is configured by integrally combining the lid member 13 with the frame member 11.

The frame member 11, the bottom member 12, and the lid member 13 are made of resin such as polyvinyl chloride resin, polystyrene resin, polyester resin, polyethylene resin, and are formed by sheet molding or injection molding. The

However, in the optical device packaging case (translucent member case) disclosed in Japanese Patent Application Laid-Open No. 2002-59989, the size of the optical device (translucent member) is different. Depending on the size, frame members etc. must be manufactured, and there is a problem that a space for accommodating various frame members etc. is necessary, and the cost of the packaging case is high because various frame members etc. are manufactured. There was a problem of becoming.

In addition, the optical device packaging case disclosed in Japanese Patent Application Laid-Open No. 2001-2167 or Japanese Patent Application Laid-Open No. 2002-370780 is also provided with a storage portion that stores the optical device according to the size of the optical device. It was necessary to make a case, and I was able to solve the same problem as above.

[0004] [Second Conventional Example]

Conventionally, as a means for packing an optical device, a packing case having a structure in which an optical device is accommodated in a plurality of concave portions having a predetermined shape provided inside a box-shaped case and covered with a lid has been used. When such a packing case is used, for example, if the packing case vibrates during transportation of the packing case, the optical device housed inside the concave inner wall of the packing case Repeating contact with the surface, the sharp end surface of the optical device is scraped on the inner wall of the tray, so that debris such as device debris and tray pieces are generated, and the debris adheres to the optical surface of the optical device and the optical surface is There was a problem of fouling.

Therefore, as a means for solving such a problem, as disclosed in Japanese Patent Laid-Open No. 2001-2167 and Japanese Patent Laid-Open No. 2002-370780, an adhesive fixing tape is attached to the bottom surface of the packaging case. Thus, it has been proposed that the optical device be bonded and held by the fixing tape.

FIG. 37 is a structural example showing a configuration of an example of a conventional packaging case for an optical device. The packaging case 21 has a plurality of concave portions 23 having a predetermined shape formed in a band shape on a packaging case main body 22, and a fixing tape 24 is attached to the bottom surface of the concave portion 23. Therefore, when the optical device 25 is stored in the packing case 21, one side of the optical device is adhered to the fixing tape attached to the bottom surface of the recess 23, and the optical device 25 is placed vertically to be self-supporting. After that, cover the lid 26 and ship. Thus, by providing the recess 23 in the packing case body 22, even if the vertically placed optical device 25 falls down due to an impact on the packing case 21, the optical device 25 stored next to it There is no contact with the optical device 25 and the optical surface of the optical device 25 is not soiled.

However, in the packaging case according to the second conventional example, the optical device is placed vertically, and when the optical device falls down, a recess is formed in the packaging case body so that it does not come into contact with the adjacent optical device. Alternatively, it is necessary to provide a guide for preventing overturning between the optical devices, resulting in a problem that the structure of the packaging case is complicated and the cost is increased.

In addition, the shape of the recess provided in the packing case body and the shape of the guide must be different according to the shape of the optical device, and there are many types of packing cases, so the work can be performed in the packing process. It was complicated and problematic.

[0006] [Third conventional example]

Optical devices (optical components) used in optical pickups and other optical devices, regardless of size, are handled to prevent damage from impacts and defective products due to foreign matter such as dust. The maximum consideration is necessary. For this reason, packaging cases that take into account the impact resistance and impact prevention of dust when transported with impacts or vibrations are conventionally used. Various proposals have been made.

On the other hand, optical devices are rapidly changing models, and the product life cycle is short. Therefore, types of optical devices that are different in size and shape are developed and commercialized one after another. For this reason, there are a wide variety of packaging cases when optical device manufacturers deliver optical devices to customers, which increases costs.

[0007] By the way, in a flat optical device such as a beam splitter, a wavelength plate, and a mirror, two opposing flat plate surface portions are optical surfaces, for example, an optical film on one of the optical surfaces. If this is formed, it is not permissible to make a mistake in the direction of assembly with the actual machine. Therefore, the orientation of the optical surfaces of the optical devices arranged in the packing case is set in one direction in advance so that the directionality can be recognized at the time of removal. Conventionally, when an optical device is packed, it is arranged and accommodated in a container in a vertically placed state, or is laid flat with either one of the optical surfaces facing upward.

In the case of a vertically placed packaging case, for example, as disclosed in JP-A-9-30593, JP-A-2001 2167, and JP-A-2002-370780, the surface on which the optical film is formed is oriented in one direction. A plurality of optical devices are fitted and disposed in the groove in a vertical posture. Furthermore, in order to clarify the directionality, a marker indicating the direction of the optical film is formed at an appropriate position of the container. However, in the case of vertical installation, when performing the work of actually taking out the individual optical devices from the container and incorporating them into the actual machine, the operator does not look closely at the marker or intends the direction of the container. If the optical device is taken out in the opposite direction, the surface on which the optical film is formed may be mistaken or cannot be discriminated.

[0008] Next, a flat packaging case is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-29679, and the optical surface is removed regardless of which direction the packaging case is oriented as compared with the vertical placement. When taking out an optical device housed in a container that is less likely to be different, the direction of the optical surface can be definitely recognized. In this conventional example, the lower peripheral edge of a flat optical device is supported by a pedestal, so the outer peripheral edge of the lower optical surface is more likely to be damaged or dust is attached, but the directionality Can definitely be recognized.

However, even in the case of flat placement, if the model of optical equipment is changed frequently In response to the new model, optical devices of different sizes will appear, so a new container will be created according to the change in the optical device size, but this is disadvantageous in terms of labor and cost. is there. Therefore, as shown in FIGS. 38 (a) and (b), a recess 301 for holding a component larger than the size of the optical device 305 is provided on the upper surface of the lower case 300, and an adhesive tape 302 is provided on the periphery thereof. By configuring the adhesive tape 302 so that both lower edges of the lower surface of the optical device 305 are attached and supported, optical devices of different sizes can be accommodated in the same container simply by changing the width dimension of the adhesive tape. I have to. Further, by closing the upper lid 310 after holding the optical device 305, the outer peripheral edge of the upper surface of the optical device may be pressed and held by the pressing convex portion 311 provided on the ceiling surface of the upper lid. In this example, the optical film 305a is coated on the upper surface of the optical device 305. However, in this case, the peripheral portion of the optical device is placed on the adhesive tape 302 as shown in FIG. However, if a slight misalignment occurs that is difficult to position, the adhesive material from the adhesive tape 302 adheres to a region important as an optical surface. Further, the position of the convex portion 311 of the upper lid 310 needs to be changed according to the size of the optical device, which is disadvantageous in terms of cost. Furthermore, in the case shown in FIG. 38 (c), the peripheral edge of the optical device can be held only on one side.

[Fourth conventional example]

Polyhedrons such as beam splitters and prisms as optical devices used in optical pickups and other optical devices are configured to have a small dimension of several mm square in response to the demand for miniaturization. First, optical devices must be handled with the utmost care in order to prevent damage caused by impacts and defective products caused by foreign objects such as dust. For this reason, various packaging cases have been proposed in consideration of impact resistance in the case of impact or vibration during transportation and prevention of adhesion of dust and the like.

For example, in Japanese Patent Laid-Open No. 2001-2167, an adhesive sheet is stretched on the bottom surface of a through hole of a case body having a through hole for accommodating an optical device, and one surface of the optical device is adhered and held by the adhesive surface of the adhesive sheet. An optical device packaging designed to do so is disclosed. In this conventional example, when an impact is applied to the bottom side force of the case body, the impact is applied. Since it is transmitted directly to the optical device, the optical device collides with the inner surface of the case main body, and damage such as damage occurs due to scraping of the inner wall of the case main body. In addition, since the structure is such that only one surface of the optical device is bonded and supported, the holding force against impact was sufficient.

[0010] Japanese Patent Application Laid-Open No. 9-30593 discloses a configuration in which an adhesive sheet is disposed on the bottom surface of the lower case via a thin cushion member, and the optical device surface is bonded and supported via the cushion member. Has been. However, this conventional example only supports one surface of the optical device through a thin cushion member in a state where the bottom surface force of the lower case is also buoyant. Therefore, depending on the applied impact and the shape of the optical device, May collide with the bottom of the case and damage it, or scraping the case to generate dust. Next, in Japanese Patent Laid-Open No. 2002-370780, the center portion of the bottom surface (non-optical surface) of the optical device is bonded and supported via a cushion by a protruding adhesive member provided on the bottom surface of the lower case, and the upper case. An air cushion provided on the ceiling surface supports the entire top surface (non-optical surface) of the optical device, and the bottom surface of the lower case made of PET supports the entire bottom surface of the optical device and the center of the top surface of the optical device. Is supported by a protrusion provided on the upper case made of PET, and the entire bottom surface of the optical device is directly adhered and supported by the bottom surface of the lower case made of PET, and an air cushion placed on the ceiling surface of the upper case. A configuration for supporting the entire top surface of the optical device is disclosed.

However, since all of the above conventional examples have a configuration in which the cushion member is arranged at a position corresponding to the side surface (optical surface) of the optical device, the lateral volume of the lower case increases, and the waste that is discarded. The problem is that the amount increases. This cushion member comes into contact with the optical surface, causing problems such as damage to the optical surface and dust adhesion. In addition, since the lower case or upper case made of PET is in direct contact with the optical device, there is an increased possibility that the PET part will be scraped and generate dust.

[0011] [Fifth conventional example]

Polyhedrons such as beam splitters and prisms as optical devices used in optical pickups and other optical devices are configured to have small dimensions of several mm square in response to the demand for miniaturization. However, regardless of the size, optical devices must be handled with the utmost care in order to prevent damage caused by impacts and defective products caused by foreign objects such as dust. For this reason, various packaging cases have been proposed in consideration of impact resistance in the case of impact or vibration during transportation and prevention of adhesion of dust and the like.

For example, in Japanese Patent Laid-Open No. 2001-2167, an adhesive sheet is stretched on the bottom surface of a through hole of a case body having a through hole for accommodating an optical device, and one surface of the optical device is adhered and held by the adhesive surface of the adhesive sheet. An optical device packaging designed to do so is disclosed. In this conventional example, when an impact is applied to the lower surface side force of the case body, the impact is directly transmitted to the optical device. Defects such as the dust generated by scraping the body wall sticking to the optical device occur. In addition, since the structure is such that only one surface of the optical device is bonded and supported, the holding force against impact was sufficient. In addition, since the case body with a through hole is made of a resin material such as PET or PS, a mold is required to manufacture the container, and the force depends on the type, shape, and size of the optical device. Therefore, there is a limit to cost reduction.

Next, Japanese Patent Laid-Open No. 9-30593 discloses a configuration in which an adhesive sheet is disposed on the bottom surface of the lower case via a thin cushion member, and the optical device surface is bonded and supported via the cushion member. Has been. However, since this conventional example only supports one surface of the optical device in a state where the bottom surface of the lower case is buoyant through a thin cushion member, depending on the applied impact and the shape of the optical device, the optical device However, there are problems such as damage caused by collision with the bottom surface of the case or scraping of the case to generate dust. In addition, since the case is made of a resin material such as PET or PS, a mold is required to manufacture the container, and the force must be manufactured individually according to the type, shape, and size of the optical device. Therefore, there was a limit to cost reduction.

Next, in Japanese Patent Laid-Open No. 2002-370780, the center portion of the bottom surface (non-optical surface) of the optical device is bonded and supported via a cushion by a protruding adhesive member provided on the bottom surface of the lower case, and the upper case. The optical device is supported by a structure that supports the entire top surface (non-optical surface) of the optical device with an air cushion provided on the ceiling, and the bottom surface of the lower case made of PET. Supports the entire bottom surface of the optical device and supports only the central part of the top surface of the optical device with a projection provided on the upper case made of PET, and also directly adheres the entire bottom surface of the optical device with the bottom surface of the lower case made of PET. A configuration is disclosed in which the entire upper surface of the optical device is supported by an air cushion disposed on the ceiling surface of the upper case while being supported.

However, since all of the above conventional examples have a configuration in which the cushion member is arranged at a position corresponding to the side surface (optical surface) of the optical device, the lateral volume of the lower case increases, and the waste that is discarded. The problem is that the amount increases. This cushion member comes into contact with the optical surface, causing problems such as damage to the optical surface and dust adhesion. In addition, since the lower case or upper case made of PET is in direct contact with the optical device, there is an increased possibility that the PET part will be scraped and generate dust. In addition, since the case is made of a resin material such as PET, a metal mold is required for manufacturing the container, and the shika also needs to be manufactured individually according to the type, shape, and size of the optical device. Therefore, there was a limit to cost reduction.

[Sixth conventional example]

Optical devices (optical elements) are used in various optical devices, and various packing methods and packing materials are used to transport optical devices from optical device manufacturers to optical device manufacturers.

For example, in the case of an optical device using a plate-like quartz crystal plate, it is easy to damage dust due to vibrations and shocks because it dislikes adhesion of dust and dirt, etc. Things are desired.

As a means for packing the optical device, there is a structure in which the optical device is accommodated in a plurality of slits of a predetermined shape provided in the box-shaped case and covered, or disclosed in JP-A-10-230975. As described above, a cushioning material in which a plurality of slits are formed in foaming resin is used to fit the four corners of a rectangular optical device into each slit, and bundle the optical devices in a state of being stacked at a predetermined interval. was there.

However, in such packaging, the optical device manufacturer has to take out the optical devices one by one from the packaging material and set them again on the assembly line of the optical device. Therefore, in recent years, it has become common to store and transport optical devices horizontally in a tray-shaped packing material so as to save the trouble of remounting the optical devices one by one on the assembly line of the optical apparatus.

For example, as disclosed in Japanese Patent Application Laid-Open No. 9-328180, there is a package that holds and holds an optical device between two flat trays.

FIG. 39 is a cross-sectional view showing the configuration of the tray-type packaging material disclosed in the above publication, and the optical device 353 is held and held between the upper tray 351 and the lower tray 352. It has been.

The upper tray 351 includes an upper tray body 354 and an upper elastic body 355, and the lower tray 352 includes a lower tray body 356 and a lower elastic body 357.

The upper and lower trays 351 and 352 are each formed with a recess at a position facing each other, and the optical device is accommodated in the recess. A step is formed in each recess, and this step contacts and holds the peripheral edge of the optical device. Each tray body 354, 356 has a material force such as PET in order to maintain a predetermined rigidity, and each elastic body 355, 357 serves as a buffer material for the optical device that comes into contact with each tray body 354, 356. It is placed between the optical device and material strength such as molten rubber is formed.

With this configuration, the optical equipment manufacturer that received this can remove the upper tray 351 and put it in the production line with the optical device mounted on the lower tray 352. There is an advantage that the complicated process of taking out the optical device and replacing it on the production line can be omitted.

[0015] Further, since the sealing property is high, the optical device is surrounded by the buffer material so that there is no possibility that the optical device is contaminated by dust during transportation, so that damage due to impact is small.

However, in the conventional packing system as shown in Fig. 39, the structure of the upper and lower trays must be changed according to the shape of the optical device.

For example, when the planar shape of the optical device is the same but only the thickness is different, specifically, an optical fiber such as an OLPF placed in front of the image sensor of a digital camera. Even if the image sensor size is the same as a filter, if the thickness must be changed according to the difference in the number of pixels, the upper tray 351 or lower tray 3 52 Therefore, it is necessary to change the uneven shape of the surface. It is necessary to redesign the mold even when changing the V and deviation tray.

In other words, if the optical device has the same planar shape but various variations in thickness, a separate tray must be prepared for each thickness of the optical device, leading to high costs. there were.

[0016] [Seventh conventional example]

Conventionally, as a means for packing an optical device, a packing case having a structure in which an optical device is accommodated in a plurality of concave portions having a predetermined shape provided inside a box-shaped case and covered with a lid has been used. When such a packaging case is used, if the packaging case vibrates while the packaging case is being transported, etc., the optical device housed inside repeatedly contacts the inner wall surface of the recess of the packaging case, and the optical device There was a problem that the optical surface of the optical device was soiled due to generation of dust due to the sharp end face being cut off.

Therefore, as a means for solving such a problem, as disclosed in Japanese Patent Laid-Open No. 2001-2167 and Japanese Patent Laid-Open No. 2002-370780, an adhesive fixing tape is attached to the bottom surface of the packaging case. Thus, it has been proposed that the optical device be bonded and held by the fixing tape. When the optical device is bonded and held with the fixing tape, the optical device is fixed and the generation of dust is prevented, but there is a problem that the adhesive of the fixing tape adheres to the optical device.

On the other hand, in manufacturing an optical device, a tray that accommodates an optical member is used to move the optical member to a post-process force as well as a pre-process force. In the optical device manufacturing process, a force that requires careful attention to prevent the optical member from being soiled. The tray is applied with a gel on the bottom surface of the tray without using an adhesive tape. The gel has a fixing force, can fix the optical member, and does not use an adhesive, so that the adhesive of the fixing tape does not adhere to the optical member. The

Specific examples of trays that use gel include Wisdom Opto-Electronic Technology, commonly known as Sticky Carrier, which moves optical components between processes. In addition, after the optical member is processed in a subsequent process, the gel sticky carrier can be returned to the previous process and used repeatedly.

However, in recent years, there has been a demand for delivery of optical devices, which are the final product, to the above-mentioned gel's state carrier and to customers, and there is an increasing demand for packing cases using gel. .

Therefore, an example of a packaging case for an optical device using a conventional gel sticky carrier is shown below.

FIG. 40 is an external view showing a configuration of a first example of a conventional optical device packaging case. Fig. 40 shows a state in which the lid of the packing case is removed. Gel 372 is applied to the entire bottom surface of the packing case main body 375, and the prism 373 is fixed on the gel 372, and the packing case main body 371 is attached to the lid 374. It is a closed structure. The gel 372 has a fixing force but does not use an adhesive, and the prism 373 is fixed without fouling the prism 373, thereby providing a packaging method having excellent vibration resistance.

FIG. 41 is an external view showing a configuration of a second case of a conventional optical device packaging case. Fig. 41 shows a state in which the lid of the packing case has been removed. The packing case body 375 is closed with a lid 377. In this example, the OLPF 375 can be mounted vertically when the OLPF 376 is mounted flat on the packing case 375 in order to increase the capacity.

FIG. 42 is an external view showing a configuration of a third example of a conventional optical device packaging case. Fig. 42 shows the packaging case with the lid removed. The entire bottom surface of the packing case body 378 is filled with [Genore 372, and the top of Genore 372 with [01 ^ PF376 fixed vertically]. Lid 379 [Structure of the packing case body 378 is closed. In this external appearance example, the vibration resistance is improved by pressing the upper part of the OLP F376 with the lid 379.

However, the conventional optical device packing case using gel sticky carrier uses an expensive gel, so the packing case is expensive, and it is used repeatedly for transportation between processes on the production line. If the packaging case is shipped with the product to the customer, the packaging case cannot be recycled and the cost of the packaging case Has been added to the product, resulting in a high manufacturing unit price.

Problems to be solved by the invention

[0019] [Problems of the first conventional example]

As described above, in the conventional example, if the size of the optical device (translucent member) is different, a frame member or the like must be manufactured according to the size, and various frame members or the like can be manufactured. There was a problem that a space for housing was necessary and a problem that the cost of the packaging case was high because various frame members were manufactured.

The first aspect of the present invention has been made in view of the above, and provides a low-cost packaging case for optical devices and a packaging method improved so as to accommodate optical devices having various thicknesses. The purpose is.

[0020] [Problem of the second conventional example]

In the packaging case according to the second conventional example, the optical device is placed vertically, and when the optical device falls down, a recess is formed in the packaging case main body so that it does not come into contact with the adjacent optical device, or between the optical devices. It is necessary to provide a guide to prevent the product from overturning. If the structure of the packaging case is complicated and the cost increases, a problem arises!

The second aspect of the present invention has been made to solve the above-described problems, and can be used for various types of optical devices for general purposes, and has a simple shape and an inexpensive packaging case. The second purpose is to provide services.

[0021] [Problem of the third conventional example]

In the third conventional example, if a slight misalignment occurs that is difficult to position when the peripheral edge of the optical device is placed on the adhesive tape, an adhesive material such as an adhesive tape is applied to an important area as an optical surface. There was a problem of sticking. Moreover, the position of the convex part of the upper lid needs to be changed according to the size of the optical device, which is disadvantageous in terms of cost. In addition, Figure 3

In the case of 8 (c), there was a problem that the peripheral edge of the optical device could not be held on one side.

The third aspect of the present invention has been made in view of the above, and is an optical device packaging case for holding and storing an optical device having two opposed optical surfaces in a flat state! In addition, optical device packaging cases that can accommodate optical devices with different sizes and outer peripheral contours can be accommodated with good positioning without causing damage by applying adhesive or applying pressure to the optical surface. The third purpose is to do.

[0022] [Problem of Fourth Conventional Example]

In the fourth conventional example, the cushion member is arranged at a position corresponding to the side surface (optical surface) of the optical device, so that the lateral volume of the lower case increases and the amount of waste to be discarded increases. Problem occurs. This cushion member also comes into contact with the optical surface, causing problems such as damage to the optical surface and dust adhesion. In addition, since the lower case or upper case made of PET comes into direct contact with the optical device, there is an increased possibility that the PET part will be scraped and generate dust.

The fourth aspect of the present invention was made in view of the above, and supported two non-optical surfaces facing each other of a cube, a rectangular parallelepiped, and other polyhedral power optical devices using a minimum buffer material. The fourth object of the present invention is to provide an optical device packaging case that can resolve optical device damage due to vibration and shock, and generation of dust and defects caused by scraping of the inner wall of the container.

[0023] [Problems of the fifth and sixth conventional examples]

In the fifth conventional example, the cushion member is arranged at a position corresponding to the side surface (optical surface) of the optical device, so that the lateral volume of the lower case increases and is discarded. The problem is that the amount of garbage increases. This cushion member also comes into contact with the optical surface, causing problems such as damage to the optical surface and dust adhesion. In addition, since the lower case or upper case made of PET comes into direct contact with the optical device, there is an increased possibility that the PET part will be scraped and generate dust. In addition, since the case is made of a resin material such as PET, a mold is required for manufacturing the container, and the force must be manufactured individually according to the type, shape, and size of the optical device. Therefore, there was a limit to cost reduction.

In the sixth conventional example, although the planar shape of the optical device is the same, but there are various variations in thickness, a separate tray must be prepared for each thickness of the optical device, which increases the cost. There was a problem of being connected to.

The fifth and sixth aspects of the present invention have been made in view of the above, and damage the optical device due to vibration shock by packing while holding the optical device using an array means having a buffer function. Another object of the present invention is to provide an optical device packaging case that can solve the problem of dust generation due to the optical device scraping the inner wall of the container.

Two adhesive tapes 36 are affixed to the back surface of the general-purpose tray 35 so that the adhesive surface has a predetermined width and extends from the window 32 provided on the tray substrate 34, and the optical device 37 includes the two adhesive tapes. Tape 3 Adhere to the adhesive surface of 6 so that the effective diameter of the optical surface of the optical device 37 does not require force. In this modification, the optical device 37 that is smaller than the optical device 28 shown in the first embodiment is stored along the long side of the window 32 provided on the tray substrate 34. The two adhesive tapes 36 to be pasted are made wider in width and the tape interval is made narrower according to the size of the small optical device 37. In this way, by adjusting the distance between the two adhesive tapes 36 applied along the long side of the window 32 provided on the tray substrate 34, or by changing the width of the adhesive tape, various optical shapes can be obtained. The device can be stored in this packing case.

Next, for example, when storing a smaller optical device 39 as in the general-purpose tray 38 shown in FIG. 6 (b), the three adhesive tapes 36 are fixed to the tray substrate 34 to improve the storage capacity. It is also possible. However, when multiple adhesive tapes are used, the center adhesive tape is only fixed at both ends, so attention should be paid to vibration and impact resistance.

FIG. 7 is a structural view showing a second embodiment of the packaging case according to the present invention, FIG. 7 (a) shows an exploded perspective view, and FIG. 7 (b) shows a stacked view. Show. In the second embodiment, the number of optical devices is increased by stacking general-purpose trays in multiple stages. The general-purpose tray 29 has a structure that can be overlapped, and the packing case 40 is a multi-stage stack of the general-purpose trays 29 for storing the optical devices 28, and the upper lid 30 and the bottom plate 31 are attached.

As described above, the general-purpose tray 29 has two adhesive tapes 33 attached to the back surface of the general-purpose tray 29 so that the adhesive surface faces the window 32 having a predetermined width and the adhesive surface provided on the general-purpose tray 29. The effective diameter of the optical surface of the optical device 28 is firmly attached to the adhesive surface 33 so as not to force. Thus, an optimal packing case 20 can be realized by arbitrarily increasing or decreasing the number of general-purpose trays 29 according to the number of optical devices 28 accommodated.

In the above embodiments, one tray substrate is provided with one window, but a single tray substrate may be provided with a plurality of windows.

[0049] [Third invention]

Next, the third aspect of the present invention will be described in detail with reference to the embodiment shown in the drawings. FIG. 8 is a front longitudinal sectional view showing the configuration of the packaging case for an optical device according to an embodiment of the third invention, FIG. 9 (a) is an external perspective view showing an example of the lower tray, and FIG. b) FIG. 9C is a front longitudinal sectional view showing a state in which the vise is held, and is an explanatory view showing a state in which the optical device is tilted.

The optical device packaging case 51 is composed of a lower case 52 and an upper case 60 that forms a space for accommodating an optical device between the lower case 52 and the upper case upper surface by being closed on the lower case 52. On the upper surface of the lower case 52, there is a recess 53 for accommodating the optical device 70 in a substantially horizontal posture (flat state). The inner wall 54 of the recess 53 is a concave curved surface whose longitudinal cross-sectional shape includes an arc shape or an elliptical arc shape. That is, the inner wall 54 has two inner wall surfaces 54a facing each other and a bottom wall 54b constituting the bottom surface curved in a concave shape toward the outer side (left and right outer sides and lower side), respectively. It has a symmetrical shape. The distance between the two inner walls 54a facing each other in the recess 53 is configured to gradually decrease in the downward direction.

The inner wall 54 is a curved surface having an arc shape, an elliptical arc shape, or any other curvature and shape, and is a surface curved concavely toward the outside of the recess 53 (concave curved surface). While protecting the optical surface, it is possible to keep the optical surface stably regardless of the size of the optical device.

The planar shape of the recess 53 is long so that a plurality of optical devices can be arranged in a line at a predetermined pitch as shown in FIG. An adhesive layer 55 is formed on at least a part (the entire surface in this embodiment) of the inner wall of the recess 53.

The optical device 70 has a rectangular flat plate shape in which at least two optical surfaces 70a and 70b face each other. For example, an optical film 70a ′ is formed on one optical surface 70a.

With the adhesive layer 55 on the inner wall of the recess 53, with the optical surface 70a facing upward, only the outer peripheral edge (the lower corner in this example) of the optical device 70 is in line contact with the adhesive layer 55, or It is configured to adhere and hold by point contact. Therefore, the adhesive does not adhere to the optical surfaces 70a and 70b, and each optical surface is not rubbed and pressed to be damaged. In particular, since the inner wall 54 has a curved surface that is concavely curved outward, the posture of the optical device 70 that is adhered and held in a line contact state or a point contact state in the recess is in a horizontal state. Even if tilted, the optical surface will not touch the adhesive layer 55 (Fig. 9 (c)). Further, since the optical device 70 is configured to be prevented from being displaced or dropped due to vibration shock by being held by the adhesive layer 55, the optical device 70 may be optically coupled by other means. I don't have to hold down the device. Since it is not necessary to use the upper case 60 as a means for holding the optical device as in the prior art, there is no problem that a part of the upper case 60 is in contact with the optical surface of the optical device.

The buffer layer can be improved by using an elastic material having cushioning properties as the adhesive layer 55 or by applying a pressure-sensitive adhesive on the cushion layer. Particularly in the present invention, as shown in FIG. 8, the distance between the inner walls 54a of the recess 53 becomes narrower as it goes downward, so that a small-sized optical device can be accommodated on the bottom side in the recess 53. As the size increases, it can be accommodated above the recess. Therefore, it becomes possible to accommodate optical devices of different sizes and shapes using this container, and the versatility is enhanced. Therefore, it is possible to eliminate the disadvantages and disadvantages of the conventional example of manufacturing and preparing a special container having a different shape and structure for each type of optical device.

[Fourth Invention]

Hereinafter, the fourth aspect of the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 10 (a) is a front longitudinal sectional view showing the configuration of an optical device packaging case according to an embodiment of the fourth invention, FIG. 10 (b) is an external perspective view showing an example of a tray, and FIG. (c) is a perspective sectional view of a main part in a state where an optical device is held.

As shown in FIG. 10 (c), this optical device packing case 81 is configured to accommodate a plurality of optical devices 100 as polyhedrons in which at least two non-optical surfaces 100a and 100b face each other in parallel. It has. The illustrated optical device 100 has a rectangular flat plate shape, and its front and rear surfaces 100c are optical surfaces.

The optical device packing case 81 includes a tray (lower case) 82 on which the upper surface is opened and the optical device 100 is placed on the upper surface (inner bottom surface) 82a, and a lid member 90 surrounding the space on the tray 82. Yes. The shape of the tray 82 may be a flat plate as illustrated, or may be a box shape.

The upper surface 82a of the tray 82 is provided with at least one long lower convex portion 83 that supports the central portion of the bottom surface in a state where the plurality of optical devices 100 are arranged in a line, and the lower convex portion 83 is flat. A cushion member 84 and a lower adhesive layer 85 that adheres to the bottom surface of each optical device are provided on the upper surface. In this example, the cushion member 84 is fixed to the upper surface of the lower convex portion 83. An adhesive layer 86 is provided for setting.

[0052] The cushion member 84 and the adhesive layers 85 and 86 constitute a lower elastic adhesive member (double-sided tape). The lower elastic adhesive member may be a member made of a single material having adhesiveness and cushioning properties.

The ceiling surface 90a of the lid member 90 is provided with at least one long upper convex portion 91 that supports the center of the upper surface of each optical device 100, and a cushion member 92 is provided on the flat lower surface of the upper convex portion 91. An upper adhesive layer 93 that adheres to the bottom surface of each optical device is provided. In this example, an adhesive layer 94 for fixing the cushion member 92 is provided on the lower surface of the upper convex portion 91.

The cushion member 92 and the adhesive layers 93 and 94 constitute an upper elastic adhesive member (double-sided tape). The upper elastic adhesive member may be a member made of a single material having adhesiveness and cushioning properties.

The tray 82 and the lid member 90 are made of a resin material such as ABS, PP, PS, or poly force. The tray 82 is not limited to a flat plate shape as illustrated, and may be a box shape having an outer wall. Further, the lid member 90 is not limited to the box shape as illustrated, and may be a flat plate shape.

As the lower and upper elastic adhesive materials, for example, an adhesive material is applied to both front and back surfaces of an elastic member made of polyurethane sheet, polyolefin, acrylic, or silicon-based resin to form a double-sided tape-like elastic adhesive material. But ヽ. A gel-like material may be used as the adhesive material.

The lower convex portion 83 and the upper convex portion 91 are set so as to face each other when the lid member 90 is closed on the tray 82. The area of the upper surface of the lower convex portion 83 and the area of the lower surface of the upper convex portion 91 are not necessarily the same.

The characteristic configuration of this embodiment is that the adhesive force of the lower adhesive layer 85 (lower elastic adhesive member) is set stronger than the adhesive force of the upper adhesive layer 93 (upper elastic adhesive member). is there.

With this configuration, when the optical device is packed, in order to arrange the optical devices 100 at a predetermined pitch on the lower adhesive layer 85 of the tray 82, the center of the bottom surface of each optical device 100 is placed on the lower side. After placing on the adhesive layer 85 and adhering and holding it, the lid member 90 is put on the tray 82 and closed while being aligned, so that the upper adhesive on the lower surface of the upper convex portion is closed. The upper and lower surfaces of each optical device can be clamped and held via the cushion members 84 and 92 while the layer 93 is bonded to the center of the upper surface of each optical device. For this reason, in the state where the lid member is closed, the optical device is held between the convex portions while being held between the convex portions, and is in a state where the optical device is held between the convex portions, so that impact and vibration are applied. However, the optical parts will not be displaced or fall between the two convex parts. In addition, since the optical component is supported at the upper and lower central portions by the upper and lower convex portions, the direction in which the optical component vibrates due to impact or the like is limited to the left-right direction, and between the inner wall of the lid member and the tray. By securing a sufficient distance between them, it collides with the inner wall or the like to damage the optical component, or the material constituting the inner wall or the like becomes dust and scatters in the container, so that the optical surface of the optical component There are no problems such as sticking to the surface.

In addition, since the adhesive force of the lower adhesive layer 85 (lower elastic adhesive member) is set stronger than the adhesive force of the upper adhesive layer 93 (upper elastic adhesive member), the optical device 100 is removed when the lid member 90 is removed. Is always held by the lower adhesive layer 85, and there is no problem that the optical device is stuck to the upper adhesive layer 93 side of the lid member and taken out.

Next, FIGS. 11 (a) and 11 (b) are front longitudinal sectional views showing the configuration of an optical device packaging case according to another embodiment of the present invention. It is explained with a mark. The characteristic configuration of the optical device packaging case according to this embodiment is that the lower protrusion 83 is composed of a plurality of small protrusions 83a, and the upper protrusion 91 is one. In the embodiment of FIG. 11 (a), the lower surface of the optical device 100 is supported by two small projections 83a at two points, and in the embodiment of FIG. 11 (b), the lower surface of the optical device 100 is supported by three small projections. Three points are supported by 83a. The elastic adhesive member composed of the adhesive layers 85 and 86 and the cushion member 84 is disposed at the tip of each small protrusion 83a as in the embodiment of FIG.

In this way, the upper side of the optical device 100 is elastically bonded and held by the lower surface of the upper protrusion 91, while the tray 82 side is elastically bonded and held by the upper surfaces of the plurality of small protrusions 83a. The holding force in the closed state of the member is increased to prevent displacement and dropout, while preventing shaking of the optical device due to vibration and impact. Furthermore, the total area of the lower adhesive layer exceeds the upper side while using materials having the same adhesive force as the lower adhesive layer (lower elastic adhesive member) and the upper adhesive layer (upper elastic adhesive member). , Inevitably, the adhesive force of the lower adhesive layer is increased, and there is no problem that the optical device is stuck to the upper adhesive layer 93 side of the lid member and taken out.

Next, FIG. 12 is a front longitudinal sectional view of an optical device packaging case according to another embodiment of the present invention. The same parts as those of the embodiment of FIG. . The optical device packaging case 81 according to this embodiment has at least one long lower convex portion that supports the center of the bottom surface of each optical device in a state where a plurality of optical devices 100 are arranged in a row on the top surface of the tray. 83 and lower elastic adhesive members 84, 85, 86 disposed on the upper surface of the lower convex portion 83 and bonded to the lower surface of each optical device, and further on the ceiling surface 90a of the lid member 90, There is provided at least one elongated upper convex portion 91 that supports the central portion of the upper surface. A cushion member is provided on the lower surface of the upper convex portion as necessary.

In this embodiment, the elastic adhesive members 84, 85, 86 are provided on the upper surface of the lower protrusion 83, while the upper convex portion 91 is configured to contact the optical device upper surface directly or via a cushion member.

According to this embodiment, since the central portion of each of the upper and lower surfaces of the optical device is supported at two points, the optical device is not only held between the convex portions with the lid member 90 closed, Since the pressure is held while being bonded to the lower convex portion 83, the optical device does not shift or drop even if an impact or vibration is applied. In addition, since the optical device is supported by the upper and lower convex portions at the upper and lower central portions, the direction in which the optical device vibrates due to impact or the like is limited to the left and right directions, and between the inner wall of the lid member and the tray. By securing a sufficient distance between the optical device and the inner wall, the optical device may collide with the inner wall, or the optical device may be damaged. Eliminates problems such as adhesion to optical surfaces. Further, since the upper convex portion 91 and the upper surface of the optical device are not bonded, the optical device can maintain the state held by the elastic adhesive member on the lower convex portion 83 when the lid member is opened.

[0056] [Fifth Invention]

The fifth aspect of the present invention will be described below in detail with reference to the embodiments shown in the drawings. FIGS. 13 (a) and (b) are a partial cross-sectional perspective view of the packaging case of the fifth aspect of the present invention, and a plan view of the state holding the optical device. FIGS. 14 (a) and (b) In one embodiment of the present invention It is the front view and end view which show the basic shape of the arrangement | sequence means which comprises the packing case for optical devices which concerns.

The packaging case 101 includes a lower case 103, a case 102 including an upper case 104 that closes an upper surface opening of the lower case 103, and an arrangement unit 111 that is supported by the lower case 103. Note that the arrangement means 111 may be supported by the upper case 104.

The arrangement means 111 is composed of at least two (four in this example) bellows sheets (bellows-like panel panels) 112 arranged in parallel with a predetermined widthwise interval w, and each bellows sheet 112 is A flexible belt-shaped sheet material of the same material and the same shape is bent into a bellows shape with a predetermined pitch (so that a sharply bent portion is repeatedly formed). And have the same longitudinal length.

As described above, in the present embodiment, a plurality of bellows erected in parallel on the bottom surface of the case with a predetermined interval w in the width direction as the array unit 111 that serially arranges the plurality of optical devices D in parallel at a predetermined pitch. The sheet 112 is used, and both end edges of the optical device D are inserted into the opening 112A formed between the pitches of the respective bellows sheets and held elastically, or are held using an adhesive. RU

As shown in FIG. 14 (b), in this example, the end face shape is a rectangular force. As will be described later, the shape of the sheet material may be selected so as to have an end face shape other than a rectangle. The sheet material constituting the bellows sheet 112 may be a metal thin plate, a resin sheet such as PET or PS, or paper. In the case of metal, a grease coating is applied. In short, as the material of the sheet material, in the state where it is formed into a bellows shape, it has sufficient shape retention so that it does not fall down, bend, or expand due to the weight of the optical device held, Select an optical device that can exhibit elasticity (panelism) that can hold the edge of the optical device with a certain amount of force.

As the shape of the sheet material, various forms can be considered as described later.

Further, depending on the usage method of the bellows sheet 112 in each embodiment to be described later, an adhesive layer may be formed in advance on the optical device holding surface of the glass sheet 112 or formed. You do n’t have to.

[0058] The lower case 103 in the case 102 shown in Fig. 13 has a configuration in which a frame body 106 is erected and fixed to the outer peripheral edge of the bottom plate 105, and two opposing wall portions 106a of the frame body 106 are provided. 106 b are formed with a plurality of cut-like locking portions 7 for inserting and supporting the locked portions 12 a protruding from both ends in the longitudinal direction of the bellows sheet 112.

The width interval w of each bellows sheet 112 is determined by the engagement of the bellows sheet to an arbitrary locking portion 7 selected from among the locking portions 7 arranged along the longitudinal direction of each wall portion 106a, 106b. Adjustment is made by locking the portion 112a. In short, the width direction interval w between the bellows sheets and the width direction position of the pair of bellows sheets 112 can be arbitrarily changed and adjusted. Another advantage is that the Jaraba sheet 112 can be easily attached and detached.

In addition, by changing the size of the case used (distance between both inner walls), the opening pitch of the bellows sheet with the same configuration can be changed, so it is commonly used to hold optical devices of different sizes and thicknesses. can do.

[0059] Also, as shown in FIGS. 13 (a) and 13 (b), the opening portions (holding portions) 112A of the two adjacent bellows sheets 112 face each other, so that the opening portions 112A facing each other The optical device D is configured so that the edges of the optical device D are fitted and held respectively.

The edge of the optical member D is protected by a sheet material of a bellows sheet constituting the opening 112A, so that it is protected even when vibration or impact is applied. Also, the case inner wall force By supporting the optical device D in a non-contact state, the optical device prevents the case inner wall from being scraped and generating dust.

By providing an adhesive layer on the inner wall surface of the opening 112A where the bellows sheet 112 holds the optical device D, the edge line of the edge of the optical device D may be held by line contact, or the bottom plate 105 By forming the adhesive layer 110 on the upper surface of the optical device D, the bottom surface of the optical device D held between the bellows sheets may be adhered and held. At this time, the adhesive layer may be formed by using a double-sided tape, or by applying a spray paste.

FIG. 15 is an end view showing a modification of the bellows sheet, FIG. 15 (a) is a substantially trapezoidal shape, and FIG. 15 (b) is a shape having a tapered portion where the width of the tip gradually decreases. is there. In short, bellows The shape of the sheet can be variously modified according to the shape and size of the optical device to be held. FIG. 16 is a main part perspective view showing another embodiment of the packaging case 101 of the present invention. In this example, an adhesive layer 115 is formed in a strip shape along both end edges of the upper surface of the bottom plate 105 of the lower case 103. Both adhesive layers 115 adhere and hold the lower sides (bottom sides) of both ends of each bellows sheet 112. In addition, if necessary, the bellows sheet 112 may be positioned by forming an adhesive layer 110 on portions other than both end edges of the upper surface of the bottom plate.

In this embodiment, the bent portion of the bellows sheet positioned on the upper surface of the bottom plate 105 is adjusted by adjusting the length (number of bent portions) of both ends of the bellows sheet 112 that is adhered and held by the adhesive layer 115 (110). The opening angle of the opening 112A can be adjusted to obtain an opening angle suitable for the optical device to be held. In other words, according to the present invention, by changing the position of the bellows sheet held by the adhesive layer 115 (110), optical devices having different sizes and thicknesses can be held using the same configuration of the bellows sheet.

Next, FIGS. 17 (a), (b) and (c) are plan views showing the packing procedure of the optical device by the packing case according to another embodiment of the present invention, on the upper surface of the bottom plate 105 of the lower case 103. The adhesive layers 110a, 110b, and 110c that also have a double-sided tape equal force are formed in a band shape along the position where each bellows sheet 112 is arranged with a predetermined width direction interval Wl. The adhesive layers 110a, 110b, and 110c are selected in width and adhesive force so that the bottom surfaces of both ends of the optical device D can be adhered and held. Each bellows sheet 112 used in this embodiment has an adhesive layer formed in advance on the inner walls of the opening portions 112A and 112B that hold the optical device D.

First, in the state of FIG. 17 (a), a bellows sheet 112 is erected on a first pitch with a predetermined pitch on the first adhesive layer 11Oa. One end of the optical device D is inserted into the opening 112A of the bellows sheet 112, and the other end of the optical component D is adhered and positioned on the second adhesive layer 110b as shown in FIG. Then, another bellows sheet 112 is erected and bonded on the second adhesive layer 110b.

Next, as shown in FIG. 17 (b), each optical device is inserted while inserting one end portion of the new optical device D into each open portion 112B on the other surface side of the bellows sheet 112 on the second adhesive layer 110B. The bottom surface of the chair is adhered and held on the second adhesive layer 110b, and the other end of the optical device D is adhered and positioned on the third adhesive layer 110c. The other end of the optical device D is inserted into the opening 112A of another bellows sheet 112 standing on the third adhesive layer 110c, and the other end of the optical device is formed by the adhesive layer formed on the inner wall of the opening 112A. Adhere and hold the ridgeline of the wire by line contact.

In FIG. 17, each bellows sheet 112 is erected and fixed in advance at a predetermined opening portion pitch on all the adhesive layers 110a, 110b, 110c in advance, and each bellows sheet is opposed to each other. The end portions of the optical device may be fitted into the portions 112A and 112B, and may be attached and held by each adhesive layer.

Alternatively, no adhesive layer is provided on the inner wall of the open part of the bellows sheet, and the optical device is erected and held only by the adhesive force of the adhesive layers 11 Oa, 110b, 110c on the top surface of the bottom plate and the elastic holding force of the open part of the bellows sheet. Even if you do it.

Also in this embodiment, since the adhesive layers 110a, 110b, 110c can arbitrarily set the opening angles of the opening portions 112A, 112B when the bellows sheet 112 is held, opticals having different sizes and thicknesses can be set. The device can be held using the bellows sheet with the same configuration.

Note that the bellows sheet used in the present invention may be widened in the axial direction by expanding what is normally compressed, or in a state where it is normally expanded. The pitch width may be narrowed by compressing the object.

[0063] [Sixth present invention]

The sixth aspect of the present invention will be described below in detail with reference to the embodiments shown in the drawings. 18 (a), (b) and (c) are a perspective view, a plan view and a longitudinal sectional view showing a state where the optical device is held in the packaging case according to the sixth aspect of the present invention, and FIG. (B) and (B) are a front view and an end view (viewed from the arrow A) showing the basic shape of the arrangement means constituting the optical device packaging case according to the embodiment of the present invention.

The packing case 121 includes a lower case 123, a case 122 including an upper case 124 that closes an upper surface opening of the lower case 123, an arrangement unit 131 supported by the lower case 123, It is configured with. Note that the arrangement means 131 may be supported by the upper case 124.

The arranging means 131 is composed of at least two coil springs 132 arranged in parallel with a predetermined width direction interval w, and each coil spring 132 is made of a wire material having the same pitch, the same size, and the same material. Configure to the same length. In this example, the end face shape is circular, but any end face shape may be used as described later. Further, the wire constituting the coil spring may be a metal or a resin. In the case of metal, apply a grease coating. As the cross-sectional shape of the wire, all shapes such as a circle, an ellipse, and a polygon (corner chamfered in an R shape) can be assumed.

The lower case 123 in the case 122 shown in FIG. 18 has a configuration in which a frame body 126 is erected and fixed to the outer peripheral edge of the bottom plate 125, and two opposing wall portions 126a and 126b of the frame body 126 are provided. A plurality of locking members (in this example, locking pins) 127 are provided on the upper surface of the respective plates in a predetermined arrangement. At both ends in the longitudinal direction of the coil spring 132 applied to the case 122, there are provided locked portions 132a that protrude in the longitudinal direction by a predetermined length and whose tips are configured in a hook shape or an annular shape. Is configured to be locked by the locking member 127. The interval w between the coil springs 132 in the width direction is set to any locking member 127 selected from a plurality of locking members 127 arranged along the longitudinal direction of the walls 126a and 126b. Adjust by locking the part 132a. Alternatively, it may be configured such that the position of the locking member 127 can be finely adjusted by moving in the width direction. In short, the interval in the width direction between the coil springs and the position in the width direction of the pair of coil springs 132 can be arbitrarily changed and adjusted.

Further, as shown in FIGS. 18 (a) and 18 (b), when each open portion (holding portion) 12A of two adjacent coil springs 132 is opposed to each other, one optical device is provided in each open portion 132A facing each other. Each end edge of D is configured to be fitted and held.

The edge of the optical member D is elastically pinched and held by the wire material of the coil spring that constitutes the opening 132A, so that it is protected even when vibration or impact is applied. In addition, by supporting the case inner wall force optical device D in a non-contact state, the inner wall of the case is not scraped by the optical device, and dust is not generated. FIGS. 20 (a) to 20 (h) are end views showing modifications of the coil spring, FIG. 20 (a) is a horizontally long oval, and FIG. 20 (b) is a horizontally long oval. Yes, these may be arranged vertically. In this way, by using a horizontally long or vertically long ellipse or ellipse, it is possible to realize an optimal holding form according to individual circumstances such as the shape and size of the optical device D as a holding object. In particular, when three or more coil springs 132 are arranged in parallel as shown in FIG. 21 and the optical device is held in a two-row configuration using a central coil spring, the horizontally long coil is used. Using a spring makes it easier to hold two rows of optical devices at the same time.

Next, in each of the embodiments shown in FIGS. 20 (c) to 20 (h), the bottom is configured to be flat so as to improve the installation stability of the lower case 123 with respect to the upper surface of the bottom plate. Fig. 20 (c) shows a semicircular shape, Fig. 20 (d) shows a shape obtained by cutting out a part of a circle in a straight line, and Fig. 20 (e) shows a vertically long oval (or oval). Figure 20 (f) shows a shape with a part of a horizontally long ellipse cut into a straight line. FIG. 20 (g) shows an arc shape with a center angle 0 of 90 degrees, and FIG. 20 (h) shows a shape obtained by cutting an ellipse or an oval shape so that the center angle is 90 degrees. By making the bottom side straight (flat) in this way, the position of the coil spring open portion (gap) 132A in contact with the edge of the optical device is specified, and stable holding can be realized. In addition, by appropriately selecting the shape of the portion other than the bottom, it is possible to realize holding suitable for each optical device.
