Abstract
Abstract A structure for mounting on a base plate an optical element having a cylindrical portion. A holder member having a flat bottom surface is rotatably mounted on the cylindrical portion of the optical element. The holder member is mounted on and secured to a support member having an inclined upper surface so that the flat bottom surface of the holder member contacts the inclined upper surface of the support member in a face-to-face manner. The support member is secured to the base plate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
232 words
A structure for mounting on a base plate an optical element having a cylindrical portion and an optical axis, comprising: a holder member, having a flat bottom surface and an opening, formed by a cylindrical inner surface, through which the cylindrical portion of the optical element penetrates, said holder member rotatably holding the cylindrical portion of the optical element; and a support member, adjustably securable to said holder member, having an inclined upper surface and a bottom surface, the flat bottom surface of said holder member contacting the inclined upper surface of said support member in a face-to-face manner, said support member capable of being secured to the base plate, the optical element being mounted on the base plate at an optimum position by aligning the optical axis of the optical element in a predetermined direction while adjusting the position of said support member under said freely rotatable holder member until the inclined upper surface of said support member is in face-to-face contact with the flat bottom surface of said holder member and the bottom surface of said support member is in face-to-face contact with the base plate, and then securing said support member to said holder member and the base plate, substantially all of the cylindrical inner surface of said holder member remaining in contact with the cylindrical portion of the optical element while adjusting the position of said support member.
Claim 2
Dependent Claim
232 words
A structure for mounting on a base plate an optical element having a cylindrical portion and an optical axis, comprising: a holder member, having a flat bottom surface and an opening, formed by a cylindrical inner surface, through which the cylindrical portion of the optical element penetrates, said holder member rotatably holding the cylindrical portion of the optical element; and a support member, adjustably securable to said holder member, having an inclined upper surface and a bottom surface, the flat bottom surface of said holder member contacting the inclined upper surface of said support member in a face-to-face manner, said support member capable of being secured to the base plate, the optical element being mounted on the base plate at an optimum position by aligning the optical axis of the optical element in a predetermined direction while adjusting the position of said support member under said freely rotatable holder member until the inclined upper surface of said support member is in face-to-face contact with the flat bottom surface of said holder member and the bottom surface of said support member is in face-to-face contact with the base plate, and then securing said support member to said holder member and the base plate, substantially all of the cylindrical inner surface of said holder member remaining in contact with the cylindrical portion of the optical element while adjusting the position of said support member.
Claim 3
Dependent Claim
33 words
A structure as set forth in claim 1, wherein said holder member and said support member are secured to each other and said support member is securable to the base plate by screws.
Claim 4
Dependent Claim
88 words
A structure as set forth in claim 2, wherein each of said holder member and said support member has openings with inner walls for guiding the screws, the openings having a size which leaves a gap between each of the screws and the inner wall of each of the openings, permitting said support member to be adjusted before being secured by the screws in a position where the flat bottom surface of said holder member contacts the inclined upper surface of said support member in the face-to-face manner.
Claim 5
Dependent Claim
13 words
A structure as set forth in claim 3, wherein the openings are cylindrical.
Claim 6
Dependent Claim
13 words
A structure as set forth in claim 3, wherein the openings are U-shaped.
Claim 7
Dependent Claim
34 words
A structure as set forth in claim 1, wherein said holder member and said support member are secured to each other and said support member is securable to the base plate by a weld.
Claim 8
Dependent Claim
21 words
A structure as set forth in claim 1, wherein the cylindrical portion can be clamped within the cylindrical hole by screws.
Claim 9
Dependent Claim
37 words
A structure as set forth in claim 1, wherein said holder member has one side having a slit with an inner end connected to the cylindrical hole through which the cylindrical portion of the optical element penetrates.
Claim 10
Dependent Claim
51 words
A structure as set forth in claim 1, wherein said holder member has a cylindrical shape with a single screw hole disposed along the axis of the cylindrical shape, said holder member and said support member being securable to the base plate by a screw passing through the single screw hole.
