    • A light beam scanning apparatus scans an object such as a stimulable phosphor sheet by applying a light beam deflected in a main scanning direction to the object while moving the object in an auxiliary scanning direction substantially normal to the main scanning direction. The light beam scanning apparatus includes first and second light detectors such as photodiodes juxtaposed in the main scanning direction and having respective light detecting surfaces extending in the auxiliary scanning direction. The first and second light detectors produce respective output signals at a predetermined ratio when the light beam for scanning the object in the main scanning direction is in a reference main scanning position, and produce respective output signals at a ratio varied from the predetermined ratio when the light beam is deviated from the reference main scanning positon. The main scanning position of the light beam with respect to the object can be detected from the ratio of the output signals of the first and second light detectors.
    • 光束扫描装置在基本上垂直于主扫描方向的辅助扫描方向上移动物体的同时,通过将主扫描方向偏转的光束施加到物体来扫描诸如可刺激的荧光体片的物体。 光束扫描装置包括第一和第二光检测器,例如在主扫描方向上并置的光电二极管,并且具有沿辅助扫描方向延伸的各个光检测表面。 当用于在主扫描方向上扫描物体的光束处于参考主扫描位置时,第一和第二光检测器以预定比例产生相应的输出信号,并且当以 光束偏离参考主扫描位置。 可以从第一和第二光检测器的输出信号的比率检测光束相对于物体的主扫描位置。

    • A cognitive function training unit including an eye-target showing unit for showing a movable eye-target on a display disposed in front of the subject's eye, an eye movement measuring unit for measuring a position and/or movement of the subject's eye, and a judgment unit for judging whether or not the subject can fixedly look at or follow the eye-target based on the position and/or the movement of the eye-target shown on the display and the position and/or the movement of the subject's eye measured by the eye movement measuring unit, and the eye-target showing unit shows the eye-target repeatedly while changing the position and/or the movement of the eye-target according to a judgment result of the judgment unit. Therefore, it is possible to show a suitable eye-target according to a symptom of a patient, whereby it is possible to conduct training efficiently.
