    • The projection optical apparatus includes light-emitting means which are disposed on a stage movable along the image plane in the projection optical apparatus and which define a light-emitting plane having a predetermined shape; photoelectric detection means which is disposed at a position substantially in conjugate relationship with a pupil of said projection optical apparatus and which receives the light emitted from the light-emitting plane of the light-emitting means through the projection optical system and a mask in which a pattern is defined at a predetermined position; and position detection means which controls the stage in such a way that the image projected on the light-emitting plane is shifted in relation to the mask pattern and which detects the superposed position between the image and the pattern in response to the light signal derived from the photoelectric detection means while the projected image is shifted and to the position of the stage.

    • This invention provides an erect type zoom telescopic optical system for a binocular or monocular telescope which consists of a positive lens group nearest to an object, a variator group, a compensator group, an image erect prism positioned between the variator and compensator groups, a field stop positioned at a predetermined definite position where the image of the object is formed by said compensator group movable along the optical axis interlocking with the variator group, and an eye-piece for observing the image of the object formed at the field stop. This invention provides a compact size system with high quality compensating aberrations.

    • A supported body, such as a display panel or liquid crystal panel, is revolvably supported by a support via a revolution shaft and secured at an arbitrary revolution angle by a lock device. The lock device includes a torsion spring having a free end and a fixed end, into which the revolution shaft is inserted in an intimately contacting state, a holding member provided to the support or supported body so as to hold the revolution shaft rotatably and having an engaging part engaged with the fixed end of the torsion spring, and a stopper member secured to the revolution shaft and abutting the free end of the torsion spring for preventing coming-off of the fixed end of the torsion spring from the engaging part. In addition, an interlocked rotating member is disposed rotatably on the revolution shaft between the stopper member and the free end of the torsion spring so as to abut to and rotate together with the free end of the torsion spring when the supported body is revolved in a reverse direction relative to the winding direction of the torsion spring. The torsion spring and the stopper member can be replaced with a pair of torsion springs disposed so as to sandwich the interlocked rotating member which is typically ring-shaped.
    • 诸如显示面板或液晶面板的支撑体通过旋转轴可旋转地支撑并通过锁定装置以任意的旋转角度固定。 锁定装置包括具有自由端和固定端的扭转弹簧,旋转轴以紧密接触的状态插入其中,保持构件设置在支撑体或支撑体上,以可旋转地保持旋转轴,并具有 与扭转弹簧的固定端接合的卡合部以及固定在旋转轴上并与扭转弹簧的自由端抵接的止动构件,以防止扭转弹簧的固定端从接合部脱落。 此外,联锁的旋转构件可旋转地设置在止动构件与扭转弹簧的自由端之间的旋转轴上,以便当支撑体旋转在扭转弹簧中时与扭簧的自由端一起抵靠旋转 与扭转弹簧的卷绕方向相反的方向。 扭转弹簧和止动构件可以用一对扭转弹簧代替,这些扭转弹簧被设置为夹紧通常是环形的互锁旋转构件。
