Title:
SHUTTER ASSEMBLY FOR LUMINESCENCE-BASED SAMPLE ANALYZER
Document Type and Number:
Japanese Patent JP2017161929
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a shutter assembly for protecting a sensitive light detector such as a photomultiplier tube against harmful exposure to light.SOLUTION: A first shutter blade has a first toothed arm and a first aperture, and a second shutter blade is positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm and a second aperture. The first and second shutter blades are supported to allow parallel linear motion. A motor has a gear that is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position, in which the first and second apertures are in an overlapping relationship with respect to each other, and a closed position, in which the first and second apertures are in a non-overlapping relationship with respect to each other.SELECTED DRAWING: Figure 1
