  The embedding cassette holder 1 of the present invention has a plurality of holding portions 11 for holding the embedding cassette C as shown in FIGS. 1 to 7, and the holding portion 11 is embedded in the embedding cassette C. It is characterized by comprising a main holding part 11a for holding the side wall Ca and a sub-holding part 11b for accommodating the bulging part Cb protruding from the bottom part of the embedding cassette C.

  Further, the storage tray 2 of the present invention is for storing a plurality of the above-mentioned embedding cassette holders 1 and, as shown in FIGS. 9 and 10, is a rectangular storage with four sides surrounded by vertical walls. And at least one of the at least one pair of opposing standing walls has at least one of the embedded cassette holders. A protrusion that engages with the notch is provided.

The embedding cassette holder 1 of the present invention has a plurality of holding portions 11 for holding the embedding cassette C as shown in FIG. The number of holding parts 11 is not particularly limited, but is preferably about 7 to 12 in terms of ease of handling. The arrangement of the holding portions 11 is not particularly limited, but is preferably arranged in a row as shown in FIG. 1 from the viewpoint of ease of handling.
As shown in FIGS. 11 and 12, the embedding cassette C includes a lid and a cassette body. In the following description, the embedding cassette C refers to a cassette body.

As shown in FIGS. 2 to 4, the holding unit 11 includes a main holding unit 11a and a sub holding unit 11b.
In the present invention, the main holding portion 11a is a portion that holds the side wall Ca of the embedding cassette C. In FIG. 2, the holding portions 11 are provided at four locations, and the position of the main holding portion 11 a is shown by rough shading in one of them (second from the right). For the convenience of fixing the side wall Ca of the embedding cassette C to the microtome, regardless of the type of the embedding cassette C, the height and the width W3 between both side walls are formed constant. Can hold the side wall of any type of embedding cassette. In the figure, 11c is a rib, which plays the role of reinforcement and can reduce the thickness, so that the raw material resin can be saved and the weight can be reduced.

  The depth D1 of the main holding part 11a is formed slightly larger than the height CH1 of the embedding cassette C (see FIG. 7). In order to make the embedding cassette C easy to put in and out and to hold the embedding cassette C stably, it is preferable to provide a clearance of about 0.1 to 0.2 mm.

  As shown in FIGS. 2 and 11, the width W1 of the main holding portion is formed to be slightly larger than the width W3 between both side walls of the embedding cassette. In order to make the embedding cassette C easy to put in and out and to hold the embedding cassette C stably, it is preferable to provide a clearance of about 0.3 to 0.5 mm.

  As shown in FIGS. 3 and 11, the depth H1 of the main holding portion 11a is such that a part of the embedding cassette C protrudes from the holding portion 11 even when the embedding cassette C having a small length CL is held. And even if it hold | maintains the embedding cassette C with big length CL, if the embedding cassette C is a grade which does not fall down, it will not specifically limit. In general, in the case of an embedding cassette circulating in the market, 15 to 30 mm is usually preferable, and 18 to 25 mm is more preferable.

  As described above, since the height CH1 of the side wall of the embedding cassette C and the width W3 between the side walls are almost constant, the embedding cassette C for processing a large specimen is shown in FIG. As shown, a bulging portion Cb that protrudes from the bottom of the embedding cassette C is used to secure an internal size. In the embedding cassette holder 1 of the present invention, the bulging portion Cb is accommodated in the sub-holding portion 11b. Note that, as described above, in FIG. 2, the position of the sub-holding portion 11b is shown by fine shading in one (rightmost) of the holding portions 11 described.

As shown in FIG. 3, the depth D2 of the sub-holding portion 11b is not particularly limited as long as the bulging portion Cb of the embedding cassette C as shown in FIG. 12 can be accommodated, and usually the height of the bulging portion Cb. It is set slightly larger than CH2. That is, since the height CH2 of the bulging portion Cb is normally about 1 to 2 mm, the depth D2 of the sub-holding portion 11b is preferably about 0.3 to 0.5 mm.
The width W2 of the sub-holding portion 11b is such that the bulging portion Cb can be accommodated and the side wall Ca is not accommodated. Specifically, the width W2 of the sub-holding portion 11b needs to be wider than the width W4 of the bulging portion Cb (not shown, but in a direction perpendicular to the length CL of the embedding cassette C), and the embedding cassette It is necessary to make it narrower than the width W3 between both side walls.

The distance H3 (see FIG. 7) from the bottom surface of the main holding portion 11a to the bottom surface of the sub holding portion 11b is set to such an extent that the embedding cassette C of the type shown in FIG. Specifically, the distance H3 from the bottom surface of the main holding portion 11a to the bottom surface of the sub holding portion 11b is usually about 2 to 7 mm, preferably about 4 to 6 mm.
That is, in the present invention, the embedding cassette C of the type shown in FIG. 11 is held by a portion (H3) from the bottom surface of the main holding portion 11a to the bottom surface of the sub holding portion 11b, as shown in FIG. If the distance H3 of this portion is smaller than 2 mm, the embedding cassette C cannot be sufficiently held, and rattling occurs, which may cause inconvenience when printing with a machine. On the other hand, if it exceeds 7 mm, the holding force is too strong and it may be difficult to insert and remove the embedding cassette C.

In the present invention, when the embedding cassette C of the type having no bulging portion as shown in FIG. 11 is inserted into the holding portion 11, as shown by a two-dot chain line in FIG. It may be inserted such that one side wall of the buried cassette C straddles the main holding portion 11a and the other side wall straddles the sub holding portion 11b. In such a case, if the bottom surface of the sub-holding portion 11b is formed in a slope shape that goes down toward the main holding portion 11a, the side wall of the embedding cassette C arranged on the sub-holding portion 11b side will be on the main holding portion 11a side. Since it slides down, the posture of the embedding cassette C is automatically corrected to the original position as shown by a broken line in FIG.
The shape of the slope is not particularly limited as long as the side wall disposed in the sub holding portion 11b slides down to the main holding portion 11a. For example, it may be a straight slope with the same inclination angle from the back side to the near side of the sub-holding portion 11b, or it is formed in a shape with rounded corners as shown in FIGS. May be.

In the present invention, since the holding part 11 is composed of the main holding part 11a and the sub-holding part 11b as described above, an embedding cassette having no bulging part as shown in FIG. Both types of embedding cassettes having a bulge as shown can also be held substantially upright.
Specifically, for the embedding cassette C of the type having no bulging portion, as shown in FIG. 7A, the embedding cassette is inserted by inserting the side wall Ca portion to the back of the main holding portion 11a. The lower end of C is held between the front side surface and the back side surface (H3 portion) of the main holding portion 11a.
On the other hand, for the type of embedding cassette C having a bulging portion, as shown in FIG. 7B, the side wall Ca is accommodated in the main holding portion 11a and the bulging portion Cb is accommodated in the sub holding portion 11b. And hold. In FIG. 7B, a space is formed in the lower part of the main holding portion 11a. However, due to the dimensional relationship between the length of the side wall Ca of the embedding cassette C and the bulging portion Cb, the space may not be formed. On the contrary, there is a case where a space is formed in the lower portion of the sub-holding portion 11b, but in any case, the cassette C is suitably held.

  In the embedding cassette holder 1 of the present invention, the arrangement of the holding portions 11 is not particularly limited, but it is preferable to arrange them in a linear shape or a matrix shape in consideration of convenience in use. In particular, as shown in FIG. 1, an embedding cassette holder 1 in which holding portions 11 are arranged in a straight line, and four sides as shown in FIG. If the storage tray 2 having a rectangular storage portion surrounded by is used, it can be used in both a linear form (FIG. 1) and a matrix form (FIG. 10) depending on the situation, so that convenience is increased.

  When the storage tray 2 as described above is used, in order to prevent the embedding cassette holder 1 from swinging in the storage tray 2, a predetermined number of embedding cassette holders 1 can be accommodated in the shape of the storage tray 2. The size is preferable. Further, when the number of embedding cassette holders 1 is less than a predetermined number, a protrusion that engages with the embedding cassette holder 1 in the storage tray 2 so that the embedding cassette holder 1 does not swing inside the storage tray 2. If the part 23 is provided, it is more preferable.

Specifically, as shown in FIG. 1, the embedding cassette holder 1 has holding portions 11 arranged in a row, and a notch portion 12 is provided at at least one of the end portions in the length direction. What was provided is mentioned. The shape of the notch 12 is preferably a shape that is narrow on the upper side and wide on the lower side, for example, a trapezoid, in order to facilitate engagement.
As shown in FIG. 9, the storage tray 2 is formed such that at least a pair of the spaces between the opposed standing walls is substantially equal to the length of the embedding cassette holder 1 and is formed on at least one of the standing walls. What provided the projection part 23 engaged with the notch part 12 of an embedding cassette holder is used. However, the shape of the protrusion 23 does not have to be the same as that of the cutout portion 12, and is engaged with the cutout portion 12 of the embedding cassette holder 1 to prevent the embedding cassette holder 1 from swinging. A shape that can be used is sufficient. Specifically, a trapezoid whose lower side is the same as the lower side of the notch 12, whose upper side is shorter than the upper side of the notch 12, and whose height is lower than the height of the notch 12. Can be illustrated.

  In the embedding cassette holder 1 and the storage tray 2 in the present invention, auxiliary structures such as a gripping portion 13 for facilitating handling by hand and a recess 14 for facilitating removal of the embedding cassette C are freely provided. Can be provided. The positions at which these configurations are provided are not particularly limited. For example, in the example shown in FIG. 1, the grip portion 13 is provided at the end of the embedding cassette holder 1, but is provided at the center or other position. Also good.

  In the present invention, the material of the embedding cassette holder 1 and the storage tray 2 is not particularly limited as long as it is a hard member having a certain degree of strength, but is preferably made of resin from the viewpoint of moldability and lightness. Examples of synthetic resins that can be used in the present invention include POM resin (polyacetal resin), ABS resin (acrylonitrile-butadiene-styrene copolymer resin), AAS resin (acrylonitrile / acrylic rubber / styrene resin), AES resin (acrylonitrile / ethylene). Propylene rubber / styrene resin), AS resin (acrylonitrile / styrene resin), PS resin (polystyrene resin), PMMA resin (polymethyl methacrylate resin), PVC resin (polyvinylidene chloride resin), MS resin (methyl methacrylate / styrene resin) , PP resin (polypropylene resin), PE resin (polyethylene resin), PBT resin (polybutylene terephthalate resin), PC resin (polycarbonate resin), and the like. Polylactic acid resin, polybutylene succine DOO, polyamide 11, biodegradable plastics and biomass plastics such as polyhydroxybutyric acid may also be used.

  As described above, the cassette main body with the lid removed is described as the embedding cassette C. However, the present invention can be similarly applied to an embedding cassette in which the lid is attached to the cassette main body. In this case, it goes without saying that the dimensional relationship described above is a dimensional relationship when the cassette body is replaced with an embedding cassette in which a lid is attached.

  As described above, according to the embedding cassette holder and the storage tray of the present invention, the embedding cassette can be suitably held, for example, using a laser marker that can be printed on the surface of a three-dimensional article. Printing can be suitably performed on various embedding cassettes.
