Description of the Related Art Generally, prior to processing a lens spherical surface, when a lens is mounted on a jig such as a lens mounting plate, it is performed by using an adhesive such as a pitch. However, in this case, problems such as "burn" and "stain" generated on the lens-attached surface due to distortion due to curing shrinkage of the patch or influence of heat of dissolution are caused.

位置に貼付面Ｓ２が形成されている。First, in FIG. 1, reference numeral 6 denotes a lens sticking dish constructed in accordance with the present invention, which comprises a sticking dish main body 8 and a lens sticking section 7. In addition, the lens attaching portion 7 has an attaching surface S2 formed at a position of a predetermined height H from a surface 8a of the attaching tray main body 8 which is the opposition.

果を得ている。On the other hand, 5 is a convex lens mounted on the attaching surface S2. Although this lens spherical surface S1 is formed with a predetermined radius of curvature, the radius of curvature of the adhering surface S2 formed by the confronting concave surface is formed to be smaller than the radius of curvature of the lens spherical surface S1. As is clear, when the lens edge is brought into contact with the attachment surface S1, a setting is made such that a minute gap h is formed at the center of the lens. This gap h is made in consideration of the fact that the lens spherical surface and the application surface S2 are entirely in contact with each other so as not to damage the lens, and that the adhesive described later can be effectively diffused to form a film having a constant thickness. Yes, specifically, good results are obtained in the range of h = 3 to 5 μm.

するためである。On the other hand, the outer diameter D of the lens affixing portion 7 is formed to be slightly larger than the outer diameter of the lens to be affixed, so that a step d occurs at the periphery when both are affixed, as will be described later. This is because a certain gap is provided between the lens and the centering chuck so that the lens can be stuck on the sticking surface S2 without bias.

貼付される。Next, in the lens attaching step shown in FIG. 5, the lens is attached to the attaching surface of the lens attaching plate. That is, the lens supply shaft 18a is lowered (in the direction of arrow C), and the lens 5 to which the adhesive 17 has been applied in the previous step is attached on the attaching surface of the lens attaching plate 6. In this case, the lens is attached with a constant pressing force so as to obtain a predetermined attaching force without damaging the lens.

を行う。Next, centering is performed by the centering step shown in FIG. 6 so that the lens is stuck to a proper position of the lens sticking plate. This operation is performed almost simultaneously with the above-mentioned sticking step. That is, in this step, the centering chuck 25 is formed, for example, in the form of a split mold, and is externally fitted to the outer periphery of the lens 5 and the outer periphery of the lens attachment 7 from opposite directions.

Since the two are in contact with each other, the thickness of the patch 17 is always constant and can be effectively suppressed to 0.01 mm or less. Therefore, the influence on the allowable deviation, which is the dimensional accuracy of the lens inner wall, is also suppressed to 0.01 mm or less. And sufficient processing accuracy can be obtained.
