An object of the present invention is to provide an optical pickup device which improves resolution of reproduced signals without increasing the number of components, and does not require positional adjustment of a grating during assembly of the optical pickup device. The F-cDNA is disposed at a plurality of predetermined positions on the slide glass of a DNA micro array chip. A display screen and a text-input keyboard are included and are each exposed at the front face of the body assembly. When reduced pressure is supplied, the system generates a force against at least a portion of the breast area of the person. The actuation feature is configured to advance the insert distally toward the distal interior surface of the end effector.
