Abstract
Abstract A method for securing optical parts together with a ring member enclosing it and functioning as a balance weight and/or a lens guard member to a support member with adhesive. The ring member is provided therein with at least one groove formed through the wall of the ring member by cutting away one portion thereof, and the optical parts, the ring member and the support member are disposed so that the optical parts and the support member may be respectively positioned adjacent both ends of the groove, and those three members are secured with adhesive applied onto the groove. With the method, those three members are simply secured to one another in one process.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A method for securing optical parts together with a ring member enclosing the optical parts to a support member, comprising the steps of: providing the ring member having at least one groove formed through a sidewall thereof; disposing the optical parts, the ring member and the support member so that an inner surface of the ring member may contact with a peripheral wall of the optical parts and an outer surface of the ring member may be positioned adjacent an upper surface of the support member; and fixedly securing one portion of the peripheral wall of the optical parts, the groove of the ring member and one portion of the upper surface of the support member to one another by applying an adhesive to the groove.
Claim 2
Independent Claim
126 words
A method for securing optical parts together with a ring member enclosing the optical parts to a support member, comprising the steps of: providing the ring member having at least one groove formed through a sidewall thereof; disposing the optical parts, the ring member and the support member so that an inner surface of the ring member may contact with a peripheral wall of the optical parts and an outer surface of the ring member may be positioned adjacent an upper surface of the support member; and fixedly securing one portion of the peripheral wall of the optical parts, the groove of the ring member and one portion of the upper surface of the support member to one another by applying an adhesive to the groove.
Claim 3
Dependent Claim
51 words
A method as set forth in claim 1, wherein the ring member is provided therein with a plurality of grooves, each formed through the sidewall of the ring member by cutting therein in a direction substantially parallel to an optical axis of the optical parts when secured to the support member.
Claim 4
Dependent Claim
24 words
A method as set forth in claim 1, wherein the ring member is a balance weight and/or a guard member of the optical parts.
Claim 5
Dependent Claim
22 words
A method as set forth in claim 1, wherein the optical parts are an objective lens for use in an optical head.
Claim 6
Dependent Claim
153 words
An optical parts holding assembly for securing to one another with adhesive optical parts, a support member whereto the optical parts are fixed and a ring member enclosing the optical parts, which is fixed to the support member, wherein the ring member is provided therein with at least one groove formed through a sidewall of the ring member by cutting therein in a direction substantially parallel to an optical axis of the optical parts when secured to the support member; and the optical parts and the other two members are disposed so that an inner surface of the ring member may contact with a peripheral wall of the optical parts and an outer surface of the ring member may be positioned adjacent an upper surface of the support member, and one portion of the peripheral wall, one portion of the upper surface and the groove are secured to one another with an adhesive.
Claim 7
Dependent Claim
153 words
An optical parts holding assembly for securing to one another with adhesive optical parts, a support member whereto the optical parts are fixed and a ring member enclosing the optical parts, which is fixed to the support member, wherein the ring member is provided therein with at least one groove formed through a sidewall of the ring member by cutting therein in a direction substantially parallel to an optical axis of the optical parts when secured to the support member; and the optical parts and the other two members are disposed so that an inner surface of the ring member may contact with a peripheral wall of the optical parts and an outer surface of the ring member may be positioned adjacent an upper surface of the support member, and one portion of the peripheral wall, one portion of the upper surface and the groove are secured to one another with an adhesive.
Claim 8
Dependent Claim
27 words
An optical parts holding assembly as set forth in claim 5, wherein the ring member is a balance weight and/or a guard member of the optical parts.
Claim 9
Dependent Claim
24 words
An optical parts holding assembly as set forth in claim 5, wherein the optical parts are an objective lens installed in an optical head.
