Abstract: PROBLEM TO BE SOLVED: To provide a sample liquid feeding apparatus capable of accurately and simply liquid-feeding a sample, and to provide a flow cytometer and a sample tube determination method.SOLUTION: A sample liquid feeding apparatus includes: a light irradiation part 41 for irradiating light; a light detection part 42 for detecting light, a light shielding part for storing a sample tube 22 and shielding light to a side face; and a tube holder 21 having a pair of light transmission parts capable of passing light. Since the tube holder 21 shields light irradiated from the light irradiation part 41 in the sample liquid feeding apparatus, a state that the tube holder 21 is installed on a predetermined position can be grasped. Since the tube holder 21 is rotated until light irradiated from the light irradiation part 41 can pass the tube holder 21, a shape of the sample tube 22 stored in the tube holder 21 can be determined by a rotated angle. The sample liquid feeding apparatus has a mechanism capable of minimizing degeneration of the sample due to heat by agitating the sample during liquid feeding.

Abstract: PROBLEM TO BE SOLVED: To align an objective lens focal position with a master disk surface by a return laser beam passing through the objective lens.
SOLUTION: When it is determined at a step S12 that focus search is successful, the master disk is positioned in the neighborhood of the focus position of the objective lens. A Z-axis motor is stopped, and an optical pickup stops. Then, at a step S14, limit data stored in memory are rewritten. A position obtained by adding a travel tolerance to the successful focus search position is specified as a safe stop position. The travel tolerance is set smaller than a working distance of the objective lens. When the focus search is not successful, the Z-axis motor is stopped when it is determined that the objective lens has reached a safe stop position. Collision between the master disk 61 and the objective lens 62 can be avoided by the stop.

Abstract: PROBLEM TO BE SOLVED: To perform control so that the surface of a master disk is positioned near the focus of an objective lens as initial setting when the resist of the master disk is exposed. SOLUTION: An objective lens 62 is vibrated in a Z direction by a sine wave of amplitude 10μm and a frequency 200Hz. When a master disk 61 is moved at a speed of 1 mm/sec., a primary straight line indicating the displacement of the master disk 61 and the displacement of the sine wave intersect each other at a plurality of spots. By monitoring the sum signal of a photodetector, a sum signal is generated in the intersecting period, and the possibility of detecting positioning is increased as compared with a method for not vibrating the objective lens 62. When the sum signal of the photodetector is detected, the z-direction movement of the master disk 61 is stopped to finish a positioning sequence. Then, a focus servo is turned on.
