    • A magneto-optical recording medium comprises a substrate, a magneto-optical recording layer formed of a rare earth metal-transition metal alloy and a dielectric protective layer overlaid in this order on the substrate, and a rare earth metal layer overlaid on an edge face of the magneto-optical recording layer. The magneto-optical recording medium wherein the substrate is annular is made by forming the magneto-optical recording layer, covering the recording region on the magneto-optical recording layer with an annular mask having an outer diameter not larger than the outer diameter of the magneto-optical recording layer and/or an inner diameter not smaller than the inner diameter of the magneto-optical recording layer, overlaying the rare earth metal layer on an outer edge face and/or an inner edge face of the magneto-optical recording layer by dispersing rare earth metal particles toward the annular mask, removing the annular mask, and overlaying the dielectric protective layer on the magneto-optical recording layer.

    • A projector of a reflection type has a transparent stage plate on which a transparent original sheet is set. A lamp illuminates the original sheet through the stage plate. A Fresnel mirror is laid on an upside of the original sheet, and reflects light from the original sheet in a convergent manner. The light from the Fresnel mirror is reflected away from the stage plate. The light is again reflected, and incident upon a projecting lens, which projects an image of the original sheet to a screen. A housing contains the Fresnel mirror in movable fashion. An inserting slot is formed in the housing, into which the original sheet is inserted during supply of the original sheet. Photo sensors operate to detect a front edge of the original sheet inserted through the inserting slot. It is also detected that the original sheet is set on the stage plate. An ejector switch is operated for ejection of the original sheet. A solenoid shifts the Fresnel mirror up away from a set position in response to a signal from the photo sensors or the ejector switch. The Fresnel mirror is shifted down to the set position in response to a sheet setting signal, to lie on the original sheet. A sheet feeder roller moves the original sheet from the inserting slot to the stage plate during the supply, and moves the original sheet out of the housing during the ejection of the original sheet.
    • 反射型投影仪具有设置有透明原稿的透明台板。 一个灯通过舞台板照亮原稿。 菲涅耳镜被放置在原稿的上侧,并以收敛的方式反射来自原稿的光。 来自菲涅耳镜的光从舞台板反射离开。 光再次被反射并入射到投影透镜上,该投影透镜将原始片材的图像投影到屏幕上。 一个壳体以可移动的方式包含菲涅耳镜。 插入槽形成在壳体中,原稿在原稿的供给期间被插入其中。 照片传感器用于检测通过插入插槽插入的原稿的前边缘。 还检测到原稿被放置在平台上。 操作喷射器开关以排出原稿。 响应于来自光传感器或喷射器开关的信号,螺线管将菲涅耳镜向上移动远离设定位置。 菲涅耳镜响应于纸张设置信号向下移动到设定位置,位于原稿上。 供纸辊在供给期间将原稿从插入槽移动到台板,并且在原稿的弹出期间将原稿从原稿移出外壳。
