Abstract: A sample analysis device includes: a motor to rotate a sample analysis substrate with a sample introduced thereon around a rotation axis of the sample analysis substrate; a drive circuit to drive the motor; a photodetector to measure a number of photons associated with a luminescence from the sample being transmitted through a window of a measurement chamber of the sample analysis substrate; and a control circuit to calculate a measurement value of the luminescence of the sample by using a number of photons measured by the photodetector while the motor rotates the sample analysis substrate.

Abstract: The optical tomography image acquisition device comprises a tomographic image computer (23) that produces tomographic image information about a measurement object, a measurement distance range deviation detector (43) that detects that the distance between a measurement object and the light input/output portion (2) of a probe is outside a measurement distance range on the basis of the computation result of the tomographic image computer (23), and a display controller (44) that outputs the computation result of the tomographic image computer (23) to a display component (17) and also sends the detection result of the measurement distance range deviation detector (43) to the display component (17).

Abstract: In an optical disc drive apparatus 10, a main arm 400 is spread by an inserted optical disc 102 as the optical disc 102 is being inserted. A main arm boss 402 slides in a predetermined direction along a disc holder control groove 225 and a main arm boss 403 slides in a predetermined direction along a disc holder rotation groove 222.
