DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gauge used for magnifying and observing or measuring an object, a sheet thereof, and a method of using the gauge.

[0002]

2. Description of the Related Art Conventionally, silver halide film gauges have been widely used as gauges for measurement. In addition, a hologram scale in which a measurement scale is formed by a hologram has been proposed. For example, a hologram scale disclosed in Japanese Patent Application Laid-Open No. 4-264214 discloses a method of forming a hologram by forming a photosensitive layer on a base material, exposing and recording interference fringes on the photosensitive layer, and then performing development processing. Indicates a scale for measurement.

The line width and pitch of the scale of the hologram scale can be formed, for example, to about several μm.
Therefore, a fine measurement object can be measured by mounting the device on a loupe, a microscope, or the like.

[0004]

However, in a silver salt type film gauge, wet development must be performed after exposure, and the accuracy of the gauge is difficult to obtain due to expansion and contraction of the film. In addition, since the scale is black, there is a problem that the scale blocks the measurement object arranged below the gauge and the scale and the measurement object cannot be visually recognized at the same time. Furthermore, since the process of exposure and development is required, it is not suitable for mass production, and there is a limit to cost reduction.

In the hologram scale, interference fringes between the object light and the reference light must be recorded in order to form a scale, and a reproduced image is formed by applying the object light or the reference light to a photosensitive material. Because it is determined by the angle of incidence and the position of the object, strict shooting conditions are required and it is practically impossible. Even if it can be done, it is useless because the image reproduction position changes depending on the incident angle of the reproduction illumination light. There was a problem.

Further, in both the silver halide film gauge and the hologram scale, when the scales are densely arranged with respect to the object to be measured, light interferes between adjacent scales at the time of photographing. There was a problem that it was not possible to record a precise scale and it was difficult to read the scale accurately.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and is intended to form a scale that is fine and accurate, and does not block a measurement object, thereby facilitating a desired dimension. It is an object of the present invention to provide a gauge, a sheet thereof, and a method of using the gauge which can be read accurately and have excellent handleability.

2) and an identification unit (11c or the like) provided on a part of the base material and capable of identifying the front and back of the gauge and the installation direction.

According to a second aspect of the present invention, in the first aspect, the base material includes a unit display section (11b) for displaying the scale unit.

A first solution of the gauge sheet comprises the gauge (10) according to the first or second solution, and a support member (21) for temporarily supporting the gauge. I do.

According to a second aspect of the present invention, in the first aspect, the gauge and the supporting member are closely adhered to each other in a peelable manner, and the adhesion surface is a pseudo-adhesion surface.

[0015] The fifth solution is the first, the third, or the fourth.
The base material of the gauge and the support member are formed from the same member.

The solution of the method of using the gauge is the method of using the gauge according to the first or second solution, wherein the identification unit identifies the front and back and the installation direction, and the object is determined based on the identification result. It is placed on the object, and the scale image is enlarged together with the object to read a desired size of the object.

[0016]

In the gauge solution, the scale is formed by a surface uneven pattern and is provided on a surface to be brought into close contact with the object. In addition, the identification unit identifies the front and back of the gauge and the installation direction. Thus, an accurate, non-obscuring scale is formed. Further, since the front and back of the gauge and the installation direction can be easily identified, the usability is good. Further, since the gauge is always correctly set, accurate measurement without defocusing or the like can be performed. Further, in the second solving means, since the unit and order of the scale can be determined in the unit display section, a desired gauge according to the magnification can be easily selected.

In the gauge sheet solution, the gauge is supported by a support member. Therefore, the ease of handling such as storage of the gauge is improved. In the second solution, the gauge is pseudo-adhered to the support member, and when the gauge is peeled from the support member, the gauge has no tackiness, so that the handleability of the gauge is further improved. Can be. In the third solution, since a plurality of gauges are provided on one supporting member, one sheet is sufficient even when a plurality of persons observe and measure an object. In the fourth solution, a plurality of gauges having different types of scales and units of the scales are provided. Therefore, it is possible to select an appropriate gauge from the plurality of gauges according to an enlargement factor, an application, and the like. it can. In the fifth solution, since the base material of the gauge and the support member are integrally formed, the manufacturing process can be simplified and the cost of the gauge can be reduced.

In the solution of the method of using the gauge,
The gauge is placed on the object based on the identification unit, and the image of the object and the scale is enlarged to read the dimensions of the object. Therefore, the dimensions of the object can be easily and accurately read.

That is,
This scale shows the case of a 100 μm grid. In addition, the scale number and the like are also displayed on the scale.

FIG. 3 is a plan view showing the configuration of an embodiment of the gauge sheet according to the present invention. The gauge sheet 20 in FIG. 3 shows an example in which ten gauges 10 in FIG. The gauge sheet 20 is formed of paper, a plastic film, or the like, and has a support member 21 that temporarily supports the gauge 10. When the gauge 10 has the dimensions described above (about 24 mm in width and about 18 mm in length),
The support member 21 is formed to have, for example, a horizontal X6 of about 63 mm and a vertical Y6 of about 113 mm. The support member 21
Is inserted into a bag (not shown) made of synthetic resin such as transparent polyester. This bag is formed to be slightly larger than the support member 21, for example, about 70 mm in width and about 120 mm in length.
m. In addition, along with the support member 21, the product name,
Paper describing simple handling instructions etc. is enclosed in the bag.

As a method of supporting the gauge 10 on the support member 21, there are, for example, the following four kinds of methods. The first method is to provide an adhesive layer on the surface of the support member 21. It is preferable that the adhesive layer does not leave the adhesive layer on the gauge 10 side when the attached gauge 10 is peeled off. For example, acrylic resin, acrylate ester resin, styrene butadiene copolymer, natural rubber, casein, gelatin, rosin ester, terpene resin, phenolic resin, styrene resin, xylene, aliphatic hydrocarbon, polyvinyl alcohol, polyethylene oxide , Polymethylene oxide, polyethylene sulfonic acid,
Vinyl chloride-vinyl acetate copolymer, etc., and, in order to appropriately adjust the adhesive strength and tack, calcium carbonate, talc, china clay, kaolin, microsilica, TiO ₂ , glass flake, asbestos, waxite powder, An inorganic fine powder such as silica stone powder, barium sulfate, Shelben, or chamotte may be added.

In the second method, the gauge 10 and the support member 21
Is a method of pseudo-adhering them, that is, a method of adhering them so that they are not tacky after peeling. This method
This is a method similar to a secret seal widely used in postcards or the like, and a method in which the amount of the inorganic fine powder of the pressure-sensitive adhesive used in the first method is increased.
In this method, it is desirable to provide the above-described protective layer 12c in order to improve the proof stress of the scale display section 12 at the time of peeling. The third method is a method of integrally forming the base member 11 of the gauge 10 and the support member 21 as shown in FIG. A slit 21a is formed in a portion corresponding to the outer peripheral portion of the gauge 10, leaving a connecting portion 21b in a part.
The user cuts and uses the connecting portion 21b. In addition to the configuration shown in FIG.
b may be provided. The fourth method is as shown in FIG.
This is a method in which a plurality of slits 21c are formed in the support member 21 ((a) in the figure), the gauge 10 is sandwiched between the slits 21c, and the gauge 10 is supported by a part of the support member 21 ((b) in the figure). ).

Next, a method of using the gauge 10 will be described. FIG. 6 is a view showing one embodiment of a method of using the gauge 10. The gauge 10 is used as a cover glass of a slide for an optical microscope. An object 53 to be measured (or observed) is placed on the slide glass 52, and an objective lens 51 is arranged above the object 53.

The gauge 10 is placed on the slide glass 52 so as to sandwich the object 53 to be measured. At this time, if the user makes the gauge 10 horizontally long and places it so that the cutout portion 11c is arranged at the upper right side (as shown in FIG. 1), the scale display portion 12 becomes lower (the object to be measured). 53), and the numbers or the like indicating the scale dimensions are arranged without turning over or reversing. That is, if the user places the gauge 10 on the basis of the identification portion of the gauge 10 (the outer shape of the gauge 10 and the position of the notch 11c), the formation surface (front and back) of the scale display portion 12 and the displayed scale are displayed. It can be placed correctly without making a mistake in the direction of the numeral (installation direction such as left and right, top and bottom). Therefore, once the gauge 10 is mounted and enlarged from the objective lens 51, it is not possible to know that the installation of the gauge 10 is not correct until the gauge 10 is installed again. Furthermore, since the unit of the scale can be known in advance by the unit display section 11b, the gauge 10 on which the desired scale is formed can be selected according to the magnification of the measurement object 53 and the like. In particular, when a plurality of gauges 10 are provided as in the case of the sheet 20, these gauges 1
When the units of the 0 scale are different, a desired gauge 10 can be easily selected from the different units.

Since the scale display section 12 of the gauge 10 is arranged on the measurement object 53 side, the measurement object 53 and the scale substantially contact. Therefore, since the thickness of the substrate 11 is not affected, defocusing is eliminated, and the dimensions of the measuring object 53 can be read very accurately. further,
Since the scale of the gauge 10 is a surface irregular pattern having reflection and transparency, even if the gauge 10 is mounted on the measurement object 53, the scale and the measurement not obstructed by the scale are obtained from the objective lens 51 of the microscope. Both images with the object 53 can be visually recognized simultaneously.

After the use of the gauge 10, the support member 21 provided with the adhesive layer or the support member 21 as shown in FIG.
Can be supported, the storage of the gauge 10 can be facilitated, and the scale can be prevented from being damaged during storage.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment.
Various modifications are possible without departing from the gist of the invention. In the gauge 10 of FIG. 1, the notch 11c, which is one of the identification portions, shows an example in which one corner of the base material 11 is linearly cut, but the present invention is not limited to this. For example, as shown in FIG. 7, (a) one in which a corner is cut out in a substantially arc shape, (b) two in the upper side are cut out in a substantially concave shape, and (c) two in the right side are substantially cut out. Notched concave,
(D) The one formed with a substantially circular opening in the vicinity of one corner or the one provided with a protruding piece at one corner as shown in (e), and formed at a position shifted from the axis of symmetry or point. Any shape may be used.

In the embodiment, the scale displayed by the scale display section 12 has a square shape, but is not limited to this. For example, as shown in FIG. 8, (a) a concentric scale, (b) a linear scale, and the like may be used. Further, the sheet 20 may be provided with a gauge having these different types of scales. In addition, the width and pitch of these scales are 10 μm as shown in the schematic enlarged view of FIG.
The pitch is not limited to 100 μm, and the width of one scale is about 2 to several 1
0 μm, the pitch is in the range of about 10 to several 100 μm,
It can be formed in arbitrary units according to the purpose of use, purpose of use, magnification of a magnifying device using the gauge 10, and the like.

In the embodiment, as an example of the method of using the gauge 10, an example in which the gauge 10 is used as a cover glass for a slide of an optical microscope was shown. However, as shown in FIG. 10 can also be used.

Further, since the identification unit is provided, the gauge can be easily and correctly set, the usability is improved, and accurate measurement can be performed. Further, since the unit of the scale can be determined in advance by the unit display unit, a desired gauge according to the magnification can be easily selected.
