Therefore, compared to the case where the support frame 64 is installed inside the glass top plate 4 through the smooth film 20 56, the thickness of the double-sided adhesive 66 is fixed, and the optical parts (61, 62) and the top plate ( Glass plate) 4 surface distance. As a result, the optical components (61, 62) can be arranged at desired positions of the top plate (glass plate) 4. Moreover, the support frame 64 can be easily assembled to the glass top plate 4 by using a double-sided adhesive anvil. 19 1235812 In addition, the capacitive switch 6 〇 and the support frame 6 4 use-the double-sided tape without the light of the display lamps 61 and 62 is installed on the glass top plate *, so 'the capacitive type can be easily The opening and supporting frame 64 are assembled on the glass top plate 4. 5 # 胄 16 The towel uses the double-sided adhesive 66 to arrange the electrostatic capacitive switch 60 and the support frame 64 in the area of “Yang Buping Lai%”, but it is also possible to use the double-sided adhesive 66 to change the electrostatic capacitive type. The switch 60 and the support frame 64 are arranged in the area where the flat top 56 is coated on the inside of the glass top plate 4. This case is useful when the placement of the display lamps 61 and 62 is correctly set to a distance of 10 from the surface of the glass plate 4 to a predetermined value. (Third Embodiment) Next, a third embodiment of the present invention will be described with reference to Fig. 17. In the π diagram replacing the 8th diagram, the support frame 53 is connected to the inside of the glass 4 using an adhesive 57 to read the state (in the state of the glass), and is applied to the domain 15 coated with the smooth film. Regarding the holding support holding mechanism in a state of being connected to the inside of the glass top plate 4, when the smoothing film 56 has a connection function, the smoothing film% can function as a holding mechanism and the adhesive 57 also has a function of a holding mechanism. Therefore, even if the support frame 53 is connected to the inside of the glass top plate 4 in a field coated with a smooth film 56, it is possible to set the optical 7 pieces (50) and the surface of the top plate (glass plate) 4 according to the design values. Distance (distance T between the substrate 52 and the upper surface of the glass top plate 4). As a result, the optical component (50) can be arranged at a desired position of the top plate (glass plate) 4. When assembling the supporting frame 53, first, as shown in FIG. 18, on the glass top 20 1235812

In a state where the uneven surface on the plate 4 faces upward, a resin as a smooth film 56 is coated on the inside of the glass top plate 4 (Step i). Then, before the resin is hardened, as shown in Fig. 19, the support frame 53 is pressed against the glass top plate 4 (step 2). At this time, a spring 5 71 ′ is arranged between the member 70 and the protruding portion 53 b of the support frame 53, and the support frame 53 is moved toward the glass top plate 4 with a fixed force F by the potential energy given by the spring 71. That is, when the support frame 53 is assembled, the spring 71 is used in order to hold the support frame 53 while being connected to the inside of the glass top plate 4. Alternatively, a mechanism for placing a heavy object on the support frame 53 or the like may be used as the pressing abutment mechanism. In addition, the spring 71 can be continuously used after the support frame 53 is assembled. 10 Furthermore, since the support frame 53 is fixed to the glass top plate 4 by a hardened resin (smoothing film 56), when this is considered to be sufficient, the adhesive 57 as a holding mechanism may be omitted. In this way, the support frame 53 can be attached to the area coated with the smoothing film 56 while being connected to the inside of the glass top plate 4. 15 In order to maintain the support frame 53 in a state of being connected to the inside of the glass top plate 4, the support frame 53 and the frame 6 may be connected as shown in FIG. 20 or FIG. 21 instead of the adhesive 57 in FIG. 17 and the like. Specifically, it is comprised as follows. The middle frame 6 of the younger brother extends below the outer periphery of the glass top plate 4, and 2 supports the top plate 4 there. Further, the fixing frame 6 and the top plate 204 are connected and fixed by an adhesive 74, and a stay 75 is disposed between the protrusion 53b of the support frame 53 and the top plate placing portion of the frame 6, and are connected by screws 76. The top mounting portion ^ of the support frame 6 and the stay 75 are connected to the protruding teeth of the support frame 53 with screws 77 at the same time. The support frame 53 can be connected to the inside of the glass top plate 4. In the case of Fig. 20, the stay 75 and the screws 76 and 77 constitute a holding mechanism 21 1235812. On the other hand, in FIG. 21, the projections 53b supporting the frame 53 are sandwiched between the projections 53b supporting the frame 53 and the inside of the glass top plate 4 by the projections 79 extending from the top mounting portion 6a of the frame body so as to be connected to the glass top plate. Keep the support frame under 4 inside. In the case of Figs. 5 to 21, the holding mechanism is formed by the protrusion 79 of the frame body 6. The above case is described in a state where the optical component is mounted on the support frame 53, but the support frame can also be mounted on the glass top plate 4 in a state where the optical component is taken out, so that when the support frame 53 is installed, the The support frame 53 is pressed against the glass top plate 4. 10 (Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to Figs. 22 and 23. In FIG. 22 instead of FIG. 8, the switch (the light emitting element 50 and the light receiving element 51) is fixed to the substrate 52, and the screw 80 is screwed to the protrusion 81 of the support frame 53 through the substrate 52. An elastic spring 82 is disposed between the projection 81 of the support frame 53 and the substrate 52, and the substrate 52 is moved by the spring 82 in a direction away from the projection 81 of the support frame by applying potential energy. The height (distance) of the substrate 52 can be adjusted by the screw 80 and the spring 82 according to the screwing position of the screw 80. In this way, the optical components (50, 51) are mounted on the support frame 53 through the substrate 52, and screws 80 and springs 20 82 as position adjustment mechanisms are provided between the substrate 52 and the support frame 53. The distance between the optical component (light emitting element 50, light receiving element 51) and the surface of the glass top plate 4 (the distance T between the substrate 52 and the top surface of the glass top plate 4) can be adjusted by the position adjustment mechanism (screw 80, spring 82). The support frame 53 can be attached (fixed) to the area coated with the smooth film 56 on the inside of the glass top plate 4 by using the adhesive 57. The T value is adjusted as described below. 22 1235812 As shown in FIG. 23, the support frame% is attached to the area where the smooth film 56 is coated on the inside of the glass 4 and the plate 4 with the adhesive 57. After the support frame μ is installed, the distance between the photon order (50, 51) and the surface of the glass top plate 4 (the distance T between the substrate M and the top surface of the glass top plate 4) is measured. Then, as shown in FIG. 22, the position adjustment mechanism (80, 82) provided in the support frame 3, specifically, the screwing position of the screw 80 is changed to adjust the optical capture member (50, 51) and the broken glass. The distance from the surface of the top plate 4 (the distance T from the base 2 to the top of the glass top plate 4). Figures 22 and 23 show the situation where the distance T1 is adjusted to T2 (< T1) after the support frame 53 is installed. In this way, compared to simply providing the supporting frame 53, the distance between the optical component (50, 51) and the top plate (the surface of the broken glass plate M (the distance between the substrate M and the top surface of the glass top plate 4) can be set according to the design value. Τ). To be more specific, when the distance is smooth and the distance τ cannot be set to the design value, or when the support frame 53 has a size error and the distance T cannot be set to the design value, the distance can still be set according to the design value. Τ Thus-come, the optical component (50) can be arranged at the desired position of the top plate (glass plate) 4 15.
