Abstract
Abstract Cross-moving stage of a microscope comprising a lower stage member supported by a support member of the microscope rotatably about the optical axis of the microscope, an upper stage member slidably supported on the lower stage member, and a clamping holder for a slide glass slidably supported on the upper stage member by a slide member guided in the upper stage member. The support member mounts thereon rotatably a first handle and a second handle coaxially with the first handle. The first handle moves the upper stage member regardless of the rotational position of the lower stage member while the first handle is kept stationarily with respect to the microscope. The second handle moves the clamping holder relative to the upper stage member by operating the second handle independently from the displacement of the upper stage member relative to the lower stage member regardless of the rotational position of the lower stage member.

Claim 1
Independent Claim
400 words
Cross-moving stage of a microscope comprising a lower stage member supported by a support member mounted on the microscope, an upper stage member slidably supported on said lower stage member so as to be moved in one direction relative to said lower stage member, and a clamping holder for a slide glass and slidably supported on said upper stage member by a first slide member secured to said clamping holder and slidably guided in said upper stage member so as to be moved relative to said upper stage member in a direction at a predetermined angle, preferably at a right angle, to said one direction of the movement of said upper stage member, wherein the improvement comprises a first handle means rotatably supported on said support member and having a first gear fixedly secured thereto, a second handle means rotatably supported on said support member and having a second gear fixedly secured thereto, a first rack fixedly secured to said upper stage member and extending in the direction parallel to said one direction of the movement of said upper stage member, and a second rack fixedly secured to a second slide member slidably guided in said lower stage member relative thereto in a direction at a predetermined angle, preferably at a right angle, to said one direction of the movement of said upper stage member, said second rack extending in the direction parallel to the direction of the sliding movement of said second slide member, pin-slot means being provided so as to operatively connect said first slide member to said second slide member, the slot of said pin-slot means extending in the direction parallel to said one direction of the movement of said upper stage member, said first gear of said first handlE means being operatively coupled with said first rack through coupling gear means rotatably supported on said lower stage member while said second gear of said second handle means is operatively coupled with said second rack through another coupling gear means also rotatably supported on said lower stage member, thereby permitting the movement each of said upper stage member and said clamping holder to be effected separately by operating either of said first and second handle means while the positions of said first and second handle means are kept stationarily with respect to the microscope regardless of the positions of said upper stage member and said clamping holder.
Claim 2
Dependent Claim
400 words
Cross-moving stage of a microscope comprising a lower stage member supported by a support member mounted on the microscope, an upper stage member slidably supported on said lower stage member so as to be moved in one direction relative to said lower stage member, and a clamping holder for a slide glass and slidably supported on said upper stage member by a first slide member secured to said clamping holder and slidably guided in said upper stage member so as to be moved relative to said upper stage member in a direction at a predetermined angle, preferably at a right angle, to said one direction of the movement of said upper stage member, wherein the improvement comprises a first handle means rotatably supported on said support member and having a first gear fixedly secured thereto, a second handle means rotatably supported on said support member and having a second gear fixedly secured thereto, a first rack fixedly secured to said upper stage member and extending in the direction parallel to said one direction of the movement of said upper stage member, and a second rack fixedly secured to a second slide member slidably guided in said lower stage member relative thereto in a direction at a predetermined angle, preferably at a right angle, to said one direction of the movement of said upper stage member, said second rack extending in the direction parallel to the direction of the sliding movement of said second slide member, pin-slot means being provided so as to operatively connect said first slide member to said second slide member, the slot of said pin-slot means extending in the direction parallel to said one direction of the movement of said upper stage member, said first gear of said first handlE means being operatively coupled with said first rack through coupling gear means rotatably supported on said lower stage member while said second gear of said second handle means is operatively coupled with said second rack through another coupling gear means also rotatably supported on said lower stage member, thereby permitting the movement each of said upper stage member and said clamping holder to be effected separately by operating either of said first and second handle means while the positions of said first and second handle means are kept stationarily with respect to the microscope regardless of the positions of said upper stage member and said clamping holder.
Claim 3
Dependent Claim
39 words
Cross-moving stage according to claim 1, wherein said second handle means is mounted coaxially with said first handle means by providing a sleeve member secured to said support member in interposed relationship between said first and second handle means.
Claim 4
Dependent Claim
45 words
Cross-moving stage according to claim 1, wherein said support member is adjustably mounted on a holder bracket which is in turn mounted on the microscope thereby permitting the centering of said support member with respect to the optical axis of the microscope to be effected.
Claim 5
Dependent Claim
252 words
Cross-moving stage according to claim 1, wherein said lower stage member is rotatably supported on said support member so as to be rotated about the optical axis of the microscope, and each of said coupling gear means and said another coupling gear means comprises a ring gear supported on said lower stage member so as to be rotated about the axis of rotation of said lower stage member and engaging with said first or second rack, each of said ring gears being coupled with said first or second gear through an idle gear freely rotatably supported on said support member so as to permit the engagement of each of said idle gears with the respective ring gears to be maintained regardless of the rotational position of said lower stage member, clamping means being provided for releasably arresting the relative rotation between said lower stage member and either of said ring gears or said support member thereby permitting said lower stage member to be rotated without changing the relative positions of said upper stage member and said clamping holder with respect to said lower stage member by clamping said ring gears against said lower stage member allowing said first and second gears to be rotated together with said first and second handle means by said ring gears through said idle gears while said lower stage member is held stationarily at its rotated position with respect to said support member by clamping said lower stage member against said support member by said clamping means.
Claim 6
Dependent Claim
147 words
Cross-moving stage according to claim 4, wherein said ring gears are axially shiftably supported on said lower stage member in overlying relation to each other, and said clamping means comprises a distance ring interposed coaxially between said ring gears and axially shiftably supported on said lower stage member while it is prevented from rotating relative to said lower stage member, and a clamping ring interposed between said support member and the adjacent one of said ring gears and threadedly engaged with said lower stage member so as to be rotated about the axis of rotation of said lower stage member, thereby permitting said ring gears to be clamped against said lower stage member in cooperation with said distance ring by rotating said clamping ring in one direction while said lower stage member is clamped against said support member by rotating said clamping ring in the opposite direction.
