Title:
SINE BAR MECHANISM FOR SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2014/108998
Kind Code:
A1
Abstract:
The present invention is a sine bar mechanism for a spectrometer comprising an electric motor (10), a screw bar (3) rotated by the electric motor (10), a frame (2) that rotatably holds the screw bar (3), a guide bar (6) that is disposed in the frame (2) parallel to the screw bar (3), and a slider (4) that is attached to the screw bar (3) and that moves in a direction along the screw bar (3) due to the rotation of the screw bar (3). The slider (4) comprises a first through-hole having a female thread on the interior face that engages with a male thread of the screw bar (3), and the slider (4) is screwed into the first through-hole. Moreover, the slider (4) has an abutting member, which is a bore through which the guide bar (6) is inserted, that abuts the exterior circumferential face of the guide bar (6). The abutting member and the guide bar (6) are attached with high dimensional precision, and thus fluctuations of the slider (4) are limited by a minute gap between the first through-hole of the slider (4) and the screw bar (3).
