Abstract: A motion state monitoring system, a training support system, a motion state monitoring method, and a program capable of suitably managing measurement results according to an attaching direction of a sensor are provided. A motion state monitoring system according to the present disclosure monitors a motion state of a target part of a subject's body. The motion state monitoring system includes an acquisition unit, an attaching direction detection unit, and a control processing unit. The acquisition unit acquires sensing information of a sensor attached to the target part. The attaching direction detection unit detects an attaching direction of the sensor. The control processing unit outputs information related to the sensing information in association with the attaching direction.

Abstract: An objective includes: an objective barrel; a plurality of lens sub-assemblies stacked in an optical axis direction of the objective in the objective barrel, each of the plurality of lens sub-assemblies including a lens and a lens frame holding the lens; and a screw member screwed into the objective barrel, the screw member pressing the plurality of lens sub-assemblies against the objective barrel along the optical axis direction of the objective. The screw member has three or more concave portions into which a jig is fitted when the screw member is screwed into the objective barrel.

Abstract: Provided is a specimen staining apparatus that includes a gap-forming member arranged to form a gap having a thickness that induces capillary action, the gap being formed above a mounting surface of a slide glass having a specimen mounted thereon; and a chemical solution supply unit that supplies a chemical solution for staining the specimen to the gap between the gap-forming member and the mounting surface so that the chemical solution spreads within the gap due to capillary action and is evenly supplied to the specimen placed on the mounting surface.
