Description of the Invention [Technical Field of the Invention] The present invention relates to an illuminometer for measuring the irradiance of ultraviolet rays. [Prior Art] An object to be irradiated with a resin, an adhesive, a paint, an ink, a photoresist, or the like Various treatments for curing, drying, melting, or softening by ultraviolet rays are widely practiced in various fields. The illuminance for ultraviolet rays irradiated to the object to be irradiated (hereinafter referred to as illuminance) is measured by using an illuminometer for ultraviolet rays. Figure 4 is a diagram showing the construction of a previous illuminometer. The illuminometer 100 includes a main body unit 200 and a light receiving unit 300, and the main unit 00 and the light receiving unit 300 are connected by a wire 400. The light receiving unit 300 is formed with a light receiving port (also referred to as a diaphragm) 310 through which ultraviolet rays are incident. The diameter of the light receiving port 310 is, for example, 3 mm. A light receiving element 320 is provided inside the light receiving unit 300. When the light receiving unit 300 is disposed in a region where ultraviolet rays are irradiated, the ultraviolet light extracted from the light receiving port 31 is incident on the light receiving element 32A. The light receiving element 3 20 outputs an electrical signal in response to the intensity of the ultraviolet light received. The output electrical signal is sent to the body portion 200 via the wire 400. The main body unit 200 has a calculation unit 210 therein. The calculation unit 210 inputs an electrical signal from the light receiving element 3 20 and converts it into an ultraviolet illuminance 値. This illuminance is displayed on the illumination unit 201221922 shown in the main body unit 200. Examples of such an illuminometer include those described in Patent Document 1 and Patent Document 2. [PATENT DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. [Problem to be Solved by the Invention] One of the uses of the treatment by ultraviolet rays described above is that only a small amount of the irradiation in a narrow region is irradiated. Matter, ultraviolet light. For example, when a lens is mounted on a reading device for a compact disc such as a DVD, an ultraviolet curable adhesive is applied between the lens and the fixing frame, and only the ultraviolet rays are irradiated to the adhesive. It is preferred that the portion other than the adhesive is not irradiated with ultraviolet rays as much as possible. For such use, an ultraviolet irradiation device called a spot irradiation device is used. In the spot irradiation device, ultraviolet rays from a lamp or an LED are formed into a dot shape having a diameter of about 5 mm by a lens or the like, and are irradiated onto the object to be irradiated. Examples of the spot irradiation device include those described in Patent Document 3 and Patent Document 4. 201221922 When measuring the illuminance of the ultraviolet ray emitted from such a spot illuminating device by using an illuminometer, it is necessary to arrange the position of the light receiving port of the light receiving portion in the region where the ultraviolet ray is irradiated. In other words, in the case of the pickup lens of the above-described example, it is necessary to arrange the light-receiving portion of the illuminometer so as to include the entire light-receiving opening having a diameter of about 3 mm in the ultraviolet irradiation region having a diameter of about 5 mm. When the entire light receiving port is not included in the ultraviolet irradiation region, the ultraviolet illuminance cannot be accurately measured. However, the ultraviolet light emitted from the spot irradiation device is, for example, ultraviolet light having a wavelength of 3 to 65 nm for curing the ultraviolet hardening type adhesive, but the light of such a wavelength is hardly visible to the eyes. Therefore, the position (area) where the ultraviolet ray is irradiated by the spot illuminating device is almost invisible. For this reason, it is difficult to know where the light receiving portion is placed, and the light receiving port can be placed in the ultraviolet irradiation region. Further, even if the illuminance display unit of the illuminance meter displays the illuminance, it is difficult to confirm whether or not the entire light receiving port is included in the ultraviolet ray irradiation region, or only the portion of the light illuminating portion is included in the ultraviolet ray irradiation region. When only a part of the light receiving port is included in the ultraviolet irradiation area, the illuminance 显示 will be lower than the actual one. Further, in the above-mentioned situation, it is not possible to know in which direction the light-receiving portion is moved, so that the entire light-receiving port can be included in the ultraviolet-irradiated region. The present invention has been invented by considering the above-mentioned problems. In the illuminance meter for ultraviolet light, it is easy to confirm whether or not the light-receiving port into which the ultraviolet light is incident is placed in the irradiation region of the ultraviolet ray, or in which direction the light-receiving port is to be moved. Within the illuminated area. [Means for Solving the Problems] The present invention for solving the above-mentioned problems is characterized in that the light-receiving port having ultraviolet light is incident and the ultraviolet light incident from the light-receiving port is received, and the light of the intensity of the light that receives the light is transmitted. In the illuminance meter for the ultraviolet ray of the light-receiving element of the sensible signal, and the illuminance meter for calculating the illuminance 紫外线 of the ultraviolet ray based on the signal from the light-receiving unit, the ultraviolet ray is converted to visible around the light-receiving port of the light-receiving unit. Light fluorescent material. When the illuminating material is configured to emit light in the vicinity of the light receiving port, it is confirmed whether or not the entire light receiving port is successfully placed in the irradiation region of the ultraviolet ray. Further, when a part of the fluorescent material around the light receiving opening is deflected, it is possible to confirm which direction the light receiving portion is moved in accordance with the position of the light emitting portion, and the entire light receiving opening can be disposed in the ultraviolet irradiation region. [Effects of the Invention] According to the present invention, by irradiating ultraviolet rays, the phosphor material surrounding the light receiving port emits light, and the region irradiated with ultraviolet rays can be visually confirmed. Therefore, the light receiving port of the light receiving portion of the illuminometer can be reliably and easily disposed in the irradiation region of the ultraviolet light irradiated in a spot shape. -8 - 201221922 [Embodiment] Fig. 1 is a view showing the structure of an illuminometer of the present invention. The illuminometer 10 includes a main body portion 2A and a light receiving portion 3A, and the main body portion 2A and the light receiving portion 30 are connected by a wire 40. The light receiving portion 30 is formed by a light receiving port (also referred to as a diaphragm) 31 through which ultraviolet rays are incident. The diameter of the light receiving port 31 is, for example, 3 mm. A fluorescent material 33 is provided around the light receiving port 21 as will be described later. Inside the light receiving unit 30, for example, a light receiving element 3 2 such as a neon diode is provided. When the light receiving unit 30 is disposed in a region where the ultraviolet ray is irradiated, the ultraviolet ray extracted from the light receiving port 31 is incident on the light receiving element 32. The light receiving element 32 outputs an electrical signal that responds to the intensity of the ultraviolet light received by the light. The output electrical signal is sent to the body portion 20 via the wire 40. Further, on the incident side of the light receiving element 32, a wavelength selective filter that passes only the diffusing plate and a desired wavelength region of the ultraviolet light is provided. The main body unit 20 has a calculation unit 21 therein. The computing unit 21 receives an electrical signal from the light receiving element 32 and converts it into an ultraviolet illuminance 値. The illuminance 转换 converted by the calculation unit 21 is displayed on the illuminance display unit 22 provided in the body unit. Furthermore, there are various types of structures in the illuminometer. For example, the signal between the light-receiving portion and the body portion is processed without using a wire, but by a wireless entrant. Further, the light-receiving portion and the main body portion are not integrally separated and are integrally formed. Further, the illuminance display unit is not provided in the main body unit, and the main body unit -9 - 201221922 is connected to, for example, a personal computer, and the illuminance 値 is displayed on the display screen of the computer and stored. Further, there is also a memory portion in the main body portion, which memorizes the illuminance of the measurement, and outputs the illuminance of the memory. Fig. 2 is an enlarged view showing a peripheral portion of a light receiving opening of a light receiving portion. As shown in the figure, a fluorescent material 33 for converting the irradiated ultraviolet light into visible light is provided around the light receiving port 31 of the light receiving portion 30. As the fluorescent material 33, for example, a crystal which is used to convert ultraviolet rays into visible light used in a laser device or the like can be used. Further, the color of the fluorescent material when the ultraviolet ray is irradiated varies depending on the type thereof, and for example, various kinds of fluorescent materials such as red, blue, and green are arranged in the vicinity of the ultraviolet ray irradiation region in the entire light receiving port 31. At the center, the periphery of the light receiving port 31 is also illuminated (radiated visible light). For example, as shown in Fig. 2(a), a concentric circular multi-circle surrounding the light-receiving port 31 is formed, or as shown in Fig. 2(b), a triangular mark (or an arrow mark) indicating the position of the light-receiving port 31 is formed. The range of the fluorescent material 33 is set such that at least a part of the fluorescent material 33 enters the ultraviolet light irradiation area (the size of the area where the spot light is irradiated, for example, a circle of Φ 5 mm) is preferable. When the crystal material 3 3 is crystallized, for example, a groove of a multiple circle or a triangle or an arrow shown in FIG. 2 is formed around the light receiving port 31 as a container of the light receiving portion, and crystals are buried in the groove. Further, as another example of the fluorescent material 33, fluorescent coating -10-201221922 may also be considered. When a fluorescent paint is used, 'the same as in the case of using crystallization', a groove is formed in the periphery of the light receiving port 31 and coated therein. The state of the fluorescent paint may not be formed into a groove, and may be applied or printed on the surface of the container of the light receiving unit 30. However, it is preferable to apply it to the groove to prevent peeling of the fluorescent coating due to friction. Fig. 3 is a view showing the positional relationship between the irradiation region of the ultraviolet ray and the light receiving port of the light receiving portion. Fig. 3 (a) shows the state of the ultraviolet irradiation region S from the spot irradiation device, away from the light receiving port 31 of the light receiving portion of the illuminometer. In this case, the fluorescent material 33 provided around the light receiving port 31 does not emit light (the visible light is not emitted). Therefore, it can be confirmed that the light receiving port 31 is not included in the ultraviolet ray irradiation region S. Fig. 3(b) shows a state in which the light receiving port 31 is located near the center of the ultraviolet irradiation region S. In this case, the honey-light material 34 around the light-receiving port 31 is illuminated by the ultraviolet rays to emit light (radiation visible light) so as to surround the light-receiving port 31. Further, in the same figure, the portion of the fluorescent material 34 that emits light is revealed by oblique lines. Thereby, the light receiving port 31 is completely contained in the ultraviolet ray irradiation region s, and it is confirmed that the entire light receiving port 31 is irradiated with ultraviolet rays. Fig. 3 (the 揭示 system reveals that the irradiation region s of the ultraviolet ray is slightly deviated from the light receiving port 31, and a part of the fluorescent material 33 (the fluorescent material for the upper right side of the light receiving port 31) is illuminated by the irradiation of ultraviolet rays. In the same situation as in Fig. 3(b), the portion of the light-emitting material 34 is illuminated by oblique lines. -11 - 201221922 In this case, it can be confirmed that the ultraviolet-irradiated region S is opposite to 31, which is located on the upper right side of the drawing. When the port 31 is irradiated, the light receiving unit 30 is moved to the upper right side, or the ultraviolet ray is moved to the lower left side. Then, the fluorescent material 34 around the light receiving port 31 is arranged to illuminate the light receiving port 31 at the same light emission position. In this way, depending on the position at which the fluorescent material 33 emits light, it is possible to accommodate the light portion or the ultraviolet ray irradiation region in which direction, and the smear 31 is disposed in the ultraviolet ray irradiation region s. As described above, the light is received by the light. Fluorescence is provided around the mouth to visually confirm the portion to which the ultraviolet ray is irradiated, so that it is easy to connect the light-receiving port. [Fig. 1] A view showing the structure of the illuminometer of the present invention. 2] The enlargement of the peripheral portion of the light receiving port of the light receiving portion is disclosed.
