Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray for accommodating a plate-like object such as a slide used for microscopic observation.

[0002]

[Prior art]

 For example, a sample to be subjected to microscopic observation is formed by adhering it onto parallel flat glass called a slide. A sample used for analysis by a physical property analyzer such as FTM (atomic force microscope) and STM (scanning tunneling microscope) is itself cut into a parallel plate. Furthermore, the substrates for thin film formation and integrated circuit formation are themselves formed as parallel plates. Further, electronic devices such as integrated circuits are often packaged in a flat plate shape.

Such a plate-like object is often stored and transported in a plate-like object storage tray 100 as shown in FIG. This is because the sample and the like extremely dislike dust adhesion, scratch formation, vibration, and impact. In FIG. 9, the tray 100 has a substantially flat plate shape, and a plurality of recesses 101 for accommodating the plate-like object S are formed on the surface thereof. The accommodating recess 101 has a rectangular opening 101a and a bottom surface 101b each having a planar shape slightly larger than that of the plate-like object S having a rectangular planar shape. The bottom surface 101b is a perfect plane, and its four sides are surrounded by side walls perpendicular to the bottom surface 101b.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional tray 100 for accommodating plate-like objects has the following problems because the bottom surface 101b of the accommodating recess 101 is completely flat. That is, as shown in FIG. 10, which is a vertical cross-sectional view of the accommodating recess 101, the bottom surface Sa of the plate-like object S was in close contact with the bottom surface 101b of the accommodating recess 101, and no floating occurred. Therefore, even if the plate-like object S is picked up from the accommodating recess 101 by a finger and taken out, the plate-like object S cannot be grasped by the finger P. Further, it was difficult to peel the plate-like object S from the bottom surface 101b due to the atmospheric pressure.

Therefore, there is no choice but to insert the tip of the finger P into the gap between the plate-like object S and the side wall 101c, hook the plate-like object S with the fingernail, raise it, and take it out. This kind of take-out method requires extra force. Therefore, the plate-like object S may be ejected with excessive force, which may give an impact or a scratch, or the plate-like object S may be touched at a portion where a finger fingerprint is present and a fingerprint may be attached to the plate-like object S. There were many.

[0006] Although it has been conventionally performed to automatically take out such a plate-like object S mechanically, in the above-described conventional plate-like object accommodating tray 100, the plate in the accommodating recess 101 is There was no configuration that regulates the position of the object S. Therefore, the accommodating position of the plate-like object S is a random, and the machine for taking it out from the accommodating recess 101 requires an advanced position sensor or the like.

When the plate-like object S is in close contact with the side wall 101c when it is considered to provide a protrusion such as a lever fulcrum in the accommodating recess, the lever-like movement of the plate-like object S may occur. It is possible that the movement trajectory interferes with the side wall 101c itself. Therefore, in such a case, it is necessary to separate the plate-like object from the side wall 101c.

[0008] Therefore, the present invention provides a plate-shaped object tray that allows the plate-shaped object to be easily taken out from the accommodating recess and allows the plate-shaped object to be positioned in the accommodated state. And

[0009]

[Means for Solving the Problems]

 The present invention adopts the following means in order to solve the above problems. That is, the plate-shaped tray according to the present invention is a plate-shaped tray provided with a concave portion for accommodating a plate-shaped object, which is composed of a bottom plate and a side wall standing upright around the bottom plate. It is characterized in that a protrusion is provided on the upper surface, and the side wall on any side facing the protrusion is an inclined surface with respect to the upper surface of the bottom plate.

The present invention can be implemented in various forms as described below. First, the plate-like material may be anything such as a sample such as a preparation or a plate-like material such as a semiconductor package.

The sidewalls need not necessarily be parallel to each other. Further, as long as at least one of the side walls of the recess is inclined with respect to the plane including the opening end of the recess, all the other side walls may be vertical or inclined.

The shape of the bottom surface of the recess is such that a projection is provided between the portion in contact with the side wall on one side and the portion in contact with the side wall on the other side. It should be Therefore, the entire bottom surface may be substantially flat and a convex portion may be formed in the middle thereof, or the entire bottom surface may be bulged in a mountain shape. When the convex portion is generated, the shape of the convex portion may be a pin-shaped protrusion or a linear protrusion. Their cross-sectional shape may be triangular, quadrangular or circular.

[0013]

[Action]

 When the plate-shaped object is housed in the housing recess, the side wall is slanted, so that the edge of the plate-shaped object slides down on the side wall. Therefore, the plate-like object can be positioned, and the plate-like object can be separated from the opening edge of the recess. Further, in this state, since the plate-shaped object rides on the protruding portion, a gap is created between the top surface of the bottom plate and the bottom surface of the plate-shaped object. Therefore, if the tip of a finger is inserted into the gap, the plate-like object can be taken out by picking up the plate-like object with this gripping tool. Alternatively, if the plate-like object is pushed from above in the part where the gap is created, the side opposite to the part where the gap is initially created will float. Therefore, it is possible to take out the plate-shaped object by picking it. In this case, since the side wall is inclined, the side wall does not interfere with the rotational movement locus of the plate-shaped object.

[0014]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the following examples, the plate-shaped material will be described as a preparation S which is a rectangular parallel plate glass.

[0015]

Embodiment 1 FIGS. 1 to 3 show a tray for plates according to Embodiment 1 of the present invention. In FIG. 1, a tray 1 as a tray for plate-like objects has a flat plate shape. Then, on the upper surface 1a of the tray 1, there are formed concave portions 2 having a rectangular opening 2a as a concave portion for accommodating a plate-like object at four places in a grid pattern. The recess is a bottom surface 2b that is parallel to the top surface 1a of the tray 1 and has substantially the same shape as the opening 2a, and four side walls 2c that are perpendicular to the bottom surface 2b formed between the four sides of the bottom surface 2b and the opening 2b. It is formed of 2d, 2e and 2f. The side walls 2c and 2d are side walls provided on the short side of the opening 2a, and the side walls 2e and 2f are side walls provided on the top side.

A triangular prism 3 having a right-angled isosceles triangular cross section whose one side has the same length (depth) as the side surface 2d is fixed to the side surface 2d. The triangular prism 3 is fixed so that the right-angled apex angle of the triangular prism fits into the right-angled corner formed by the side surface 2d and the bottom surface 2b. Therefore, the upper and lower edges of the slope 3a of the triangular prism 3 are in contact with the top surface 1a of the tray 1 and the bottom surface 2b of the recess 2 at the same height. The triangular prism 3 has the same length as the side surface 2d. Therefore, there is no gap between the side surfaces 2e and 2f.

Further, the distance from the boundary line 3b between the slope 3a and the bottom surface 2b to the opposite side surface 2c is set to be slightly longer than the length of the long side of the preparation S, which is the object to be accommodated. Moreover, the distance between the side surfaces 2e and 2f on the long side is set to be slightly longer than the length on the short side of the slide S.

A quadrangular prism 4 serving as a protruding portion is fixed on the bottom surface 2b, which is slightly closer to the side wall 2c than the intermediate portion between the triangular prism 3 and the side wall 2c. The quadrangular prism 4 is provided parallel to the side wall 2c. The height of the quadrangular prism 4 is set so that the entire quadrangular prism 4 fits below the line connecting the edge of the opening 2a on the side wall 2c side and the boundary line 3b. The length of the prismatic column 4 is also set to be the same as that of the side walls 2c and 2d. Therefore, no gap is formed between the side surfaces 2e and 2f.

Next, the operation of the plate-shaped tray according to the first embodiment having the above-described configuration will be described with reference to FIGS. 3 and 4. First, when the slide S is housed in the recess 2, the edge of the slide S slides down on the slope 3a and stops at the boundary line 3d, as shown in FIG. Therefore, the preparation S is automatically positioned with respect to the recess 2. In this state, since the slide S is riding on the square pole 4, one end of the slide S is lifted from the bottom surface 2b. However, due to the height condition of the square pole 4, the extension line of the bottom surface Sa of the preparation S (indicated by a dotted line in FIG. 3) interferes with the side surface 2c. Therefore, even if the tray 1 is vibrated or tilted, the slide S 1 does not slip out of the recess 2.

In the stored state shown in FIG. 3, by inserting the tip of the finger P into the gap between the bottom surface Sa of the slide S and the bottom surface 2b of the recess 2 and grasping the raised end portion Sb, it becomes easy. The slide S can be taken out from the recess 2.

Further, the floating end of the slide S in the storage state shown in FIG. 3 is pressed by Sb from above with Sb. Then, as shown in FIG. 4, the end portion Sb sinks and the opposite end portion Sc largely floats. Therefore, by grasping the raised end Sc with a finger, the slide S 1 can be more easily taken out from the recess 2. In this case, since the slope 3b recedes toward the side wall 2d as it goes upward, it does not interfere with the rotational movement trajectory of the slide S.

As described above, the tray for plate-like object according to this embodiment can easily position the slide S at the time of accommodation, so that it is sufficiently applicable to automatically take out the slide S by a machine. be able to.

[0023]

Second Embodiment FIG. 5 shows a tray for plate-like objects according to a second embodiment of the present invention. Example 2 is carried out in that the triangular pillar 3 is not provided and the side wall 2d itself is an inclined surface, and instead of the square pillar 4, a semi-cylindrical protrusion 5 of a kamaboko shape is integrally formed. Different from Example 1. Since other configurations and operations are the same as those of the first embodiment, the description will be omitted.

[0024]

Third Embodiment FIG. 6 shows a tray for plate-like objects according to a third embodiment of the present invention. In each of the above-described embodiments, the protrusions 4 and 5 are formed as columnar objects having a horizontal axis having a length in contact with the long side walls 2e and 2f. On the other hand, in the third embodiment, the bulging portion is formed as a cylinder 6 having an axis perpendicular to the surface direction of the bottom surface 2b. Therefore, the column 6 and the side walls 2e and 2f are not in contact with each other.

The other configurations and operations in the third embodiment are the same as those in the first embodiment, and therefore the description thereof will be omitted.

[0026]

Fourth Embodiment FIGS. 7 and 8 show a tray for plates according to a fourth embodiment of the present invention. In each of the above-described embodiments, the bottom surface 2b of the recess 2 is formed as a plane parallel to the top surface 1a of the tray 1, and the protrusions 4, 5, 6 are formed as protrusions protruding from the bottom surface 2b. On the other hand, the fourth embodiment is characterized in that the bottom surface of the concave portion 2 and the bulging portion are integrated.

That is, as shown in FIG. 7, the bottom surface 7 of the recess 2 is composed of two slopes 7 a and 7 b whose ridge lines are the boundary lines 7 c of each other. Therefore, the entire structure is the bottom surface 7 that bulges like a mountain range.

FIG. 8 shows a state in which the slides S are accommodated in the plate-shaped tray according to the fourth embodiment. As shown in FIG. 8, the slide S is in contact with the slope 7a on one side and is stably held in a state of being lifted from the slope 7b on the other side.

Therefore, as in the first embodiment, if the tip of a finger is inserted into the gap between the bottom surface Sa of the slide S and the slope 7b and the raised end Sb is gripped, the recess 2 can be easily removed. It can be taken out from the slide S. Further, if the floating end of the slide S is pressed from above by Sb by the pressing means, this end Sb sinks with the boundary line 7c as a fulcrum, and the opposite end Sc largely floats. Therefore, by grasping the raised end Sc with a finger, the preparation S can be more easily taken out from the recess 2.
