[0007] The joining to the stopper 52 is first performed.
The armor 53 is pressed in the direction A, and in this state, the lens edge holding plate 52b of the stopper 52 is used, for example, by using a brazing method.
Is performed in such a manner as to be joined to the outer peripheral surface of the substrate.

The armor 53 is generally made of a blanker Z material (a quaternary alloy of copper, nickel, zinc and tin).

The temples 54 are connected to each armor 53 by a suitable connecting shaft (not shown) inserted through a hinge 53a of the armor 53 so as to be openable and closable within approximately 90 degrees. And is generally made from a high nickel material.

In order to connect 51 ', both ends are configured as members that come into contact with the back surfaces of the inner portions of both spectacle lenses 51 and 51', and are generally made of high nickel material.

A pad 5 comprising a pair of nose pads and pad legs
6 is configured as a member integrally connected to the bridge 55, and the pad legs are generally made of a nickel-white material.

Now, the stopper 5 for the spectacle lens 51
The attachment (fixation) of 2 is performed by the following method.

As shown in FIG. 8, first, the lens edge pressing plate 52b of the stopper 52 is brought into contact with the edge surface of the eyeglass lens 51, and the eyeglass lens 51 is pressed from the back (concave) side of the eyeglass lens 51 by the lens pressing plate 52a. And the mounting hole 52c of the stopper 52 and the outer lens hole 51a of the spectacle lens 51 are aligned.

In this state, the nylon-made washer sleeve 62 of the first fixing means 61 is fitted into the outer lens hole 51a from the front (convex) side of the spectacle lens 51, and the female screw washer 63 is inserted. The eyeglass lens 51 is fitted into the mounting hole 52c of the stopper 52 from the back side.

Then, the screw 64 of the first fixing means 61 is

Thereafter, the screw 64 is tightened, and the spectacle lens 51 is attached to the sleeve 6 with the washer of the first fixing means 61.
2 washer portion and lens holding plate 52 of stopper 52
a so as to be firmly clamped between them.

On the other hand, the bridge 55 is attached (fixed) to the left and right spectacle lenses 51 and 51 'in the following manner.

As shown in FIG. 9, first, the second fixing means 71
Is fitted into the inner lens hole 51b from the front side of the spectacle lens 51.

Then, in this state, the screw 73 of the second fixing means 71 is inserted into the inner lens hole 51b through the sleeve 72 with the washer, and penetrates to the bridge 55, and the female screw portion formed in advance on the bridge 55 side ( (Not shown) and tighten the screw 73 to fix the eyeglass lens 51 firmly between the washer portion of the washer sleeve 72 of the second fixing means 71 and both ends of the bridge 55. I do.

By the way, the frameless glasses constructed in this manner are temporarily assembled on the manufacturer's side by provisional eyeglass lenses (dummy lenses) and eyeglass frames 52 to 73 to form a finished product, which is supplied to the dealer. It is a distribution system that does.

Therefore, when providing the wearer with frameless glasses for the purpose of correcting vision, the dummy lens attached by the manufacturer must be replaced with a wear lens 51 having a lens power suitable for the wearer's vision. Must.

At this time, the replacement work includes a step of cutting the wearing lens 51 specified in power according to the lens shape,
A step of determining the positions of the outer lens hole 51a and the inner lens hole 51b to be drilled with respect to the wearing lens 51; and, as shown in FIG.
And a step of combining the spectacle frames 52 to 73 with the wearing lens 51 using both the processed lens holes 51a and 51b.

In this case, in the step of determining the positions of the outer lens hole 51a and the inner lens hole 51b for the wearing lens 51, the hole positions are conventionally determined by the following method.

That is, in one example, as shown in FIG. 10, first, the dummy lens 81 is placed on the wearing lens 51 so as to be overlapped as accurately as possible, and then formed at the stage of temporary assembly. Through the tip of the drill 91 along the outer lens hole and the inner lens hole of the dummy lens 81
A triangular mark (point) indicating the position of the hole of the stopper 52 was put on the surface of the wearing lens 51.

Another example is disclosed in Japanese Patent Application Laid-Open No. 63-6521.
As disclosed in FIG. 5 of the publication, a grid-like line for determining the eye point position (publication code, 14a) and a stopper hole point for determining the hole position for the stopper (publication code, 12a and 12a).
b) is prepared and a reference mark (publication code, 10) is drawn.
A wearable lens (publication code, 3b) subjected to edging is placed on this indicator to determine the position of the hole for the stopper.

[0026]

However, in the former example, since the dummy lens 81 and the wearing lens 51 have different curvatures from each other, it is difficult to fix and mount the two in parallel. In addition, even if the drill 91 is passed through the outer lens hole and the inner lens hole of the dummy lens 81, the guide does not become a complete guide, and there is a possibility that blurring due to the difference in the hole diameter may occur.

On the other hand, in the latter example, as shown in FIG. 11, there is a relationship between the part where the hole on the side of the wearing lens 51 (publication code, 3b) is opened and the indication mark 100 (publication code, 10). Parallax was apt to occur, and the drilling position was sometimes shifted.

Further, a problem common to both examples is that, since the surface of the lens 51 is spherical, the tip (edge) of the drill 91 does not become perpendicular to the lens surface. This means that the tip of 91 may slip and damage the lens surface.

The present invention has been made in view of such circumstances, and an object of the present invention is to form a mounting hole for a spectacle frame in an edgeless spectacle lens and accurately determine a mounting hole position on the surface of the spectacle lens. And a spectacle frame mounting hole indication sign sheet for a frameless spectacle lens and a spectacle frame, which are less likely to scratch the surface of the spectacle lens even if the tip of the drill slides during drilling. Another object of the present invention is to provide a guide sheet for forming a mounting hole, and another object is to form a spectacle frame mounting hole in a frameless spectacle lens using the spectacle frame mounting hole indicating mark sheet and the mounting hole forming guide sheet. An object of the present invention is to provide a mounting hole forming method.
