プ）。[0003] This pressure-measuring film is a film in which a color former layer containing microcapsules containing a color former is coated on a support (referred to as an A film), and a film in which a developer is applied to a support (referred to as a C film). The color developing agent is adsorbed on the color developing agent by destroying the microcapsules at the pressurized portion, and a red color is developed by a chemical reaction (two-sheet type). Further, a developer and a color former in microcapsules are applied to one support,
There is also a type in which a microcapsule at a pressurized portion is broken to cause a color former in the microcapsule to react with a developer (mono-sheet type).

タイプが主として用いられている。In this type of pressure measurement film, the detection pressure can be changed by using microcapsules having different breaking pressures. As a sheet for detecting pressure below a low pressure, a two-sheet type in which two films are stacked is mainly used in order to prevent color development due to careless contact and facilitate handling.

あった。On the other hand, in recent years, particularly in the technical field of bonding semiconductors and liquid crystals, it is necessary to detect a pressure lower than 0.2 MPa. There is a problem that the conventional pressure measuring film cannot meet such a demand.

発色させるものである。Therefore, a method has been proposed in which a rubber elastic mat having a large number of convex portions formed on one surface is used in combination. In this method, the convex portion of the elastic mat is applied to the pressure measuring film to press the other flat surface of the elastic mat. Then, the pressure applied to the flat surface of the elastic mat is concentrated on the tips of the convex portions to press the pressure measuring film to develop the color of the film.

Therefore, it is difficult to easily know the magnitude and pressure distribution of the pressurizing pressure, the shape of the pressurizing surface of the pressurizing object, etc. only by looking at this film. For this reason, it takes a considerable skill to judge these things by looking at this film.

して３次元表示としても良い。The tip of the convex portion of the elastic mat is deformed by pressurizing the pressure measuring film, and the contact area thereof increases as the applied pressure increases. Therefore, the pressure applied to the convex portion can be known from the area of the color-developed region of the pressure measuring film. By thus knowing the pressure distribution for each pressurizing point, the two-dimensionally continuous pressure distribution can be known. For example, the pressure distribution between adjacent pressure points can be known by interpolating using the pressure distribution of the pressure points around it. Then, by connecting points of a predetermined pressure, the equal pressure line can be displayed two-dimensionally in color. A three-dimensional display may be performed by setting the magnitude of pressure to be high.

Film applied to 8 (hereinafter referred to as A film) 20
And a film (hereinafter, referred to as a C film) 26 in which the developer layer 22 is coated on a support 24 and used.

They are superimposed as shown in FIG. That is, C film 2
The color former layer 16 of the A film 20 is brought into close contact with the color developer layer 22 side of No. 6, and the projection 12 of the elastic mat 10 is brought into contact with the A film 20. In this state, an object to be measured (not shown) is placed on the flat surface of the elastic mat 10 and pressed.

る。As shown in FIG. 1 (B), the convex portions 12 of the elastic mat 10 are formed at equal intervals one by one with respect to the constant area S1, so that the pressure Po applied to this area S1 is concentrated. To the tip of the convex portion 12. That is, since the pressure is a force F per unit area (the unit is N or kg), for example, a unit of Pa (Pascal) or kgf / m 2 is used.
By concentrating the same force F on the tip portion by the convex portion 12, the area can be reduced and the pressure can be increased.

能な圧力範囲を広げることができる。For example, the conical bottom surface area of the convex portion 12 is S1.
And the contact area of the convex portion 12 with the film 14 is S2
Then, the pressure is amplified to Po × (S1 / S2).
When the amplified pressure falls within the measurable pressure range of the film 14, the color developer layer 22 of the C film 26 develops a color.
That is, the microcapsules of the A film 20 are broken, and the color developing agent therein chemically reacts with the color developing agent layer 22 to cause the color developing agent layer 22 to develop color. For this reason, the measurable pressure range of the film 14 can be expanded.

The pressure point reading means 34 takes in the output of the scanner 30 and obtains the coordinate position and area S2 of each pressure point 28. The pressure detecting means 36 calculates the pressure Po corresponding to this area S2. That is, a conversion table, a map, or a conversion formula for obtaining the conversion of the pressure Po corresponding to the area S2 is stored in advance in a look-up table (LUT) 38, and the pressure detection means 36 uses the LUT 38 to calculate the pressure Po.
