    • The magnetic recording reproducing apparatus is of a type in which magnetic tape is loaded approximately parallel to a reference plane of a cassette, and in a tape guide group on magnetic tape take up side of a rotary head drum, a first take up side inclined guide on which magnetic tape is wound around immediately after it moves away from rotary head, a take up side guide roller arranged downstream and a second take up side inclined guide are included. Height of a lead formed at a fixed portion of rotary head drum is set such that it becomes lower than the lower end of the magnetic tape for its entire region, at the time of loading and unloading of the magnetic tape. By this structure, contact between the lower end of the magnetic tape and the edge of the lead at the time of loading and unloading of the magnetic tape can be avoided, and therefore damage on the magnetic tape caused by the lead edge can be prevented, and the life of the tape can be made longer.
    • 磁记录重放装置是一种类型,其中磁带大致平行于盒的基准面加载,磁带上的磁带引导组中卷绕旋转磁鼓的侧面,第一卷绕侧倾斜导向件 磁带在离开旋转头后立即缠绕在其上,包括布置在下游的卷绕侧引导辊和第二卷绕侧倾斜导向件。 形成在旋转磁头鼓的固定部分处的引线的高度被设定为在磁带的装载和卸载时,它的整个区域变得低于磁带的下端。 通过这种结构,可以避免在磁带的装载和卸载时磁带的下端与引线的边缘之间的接触,因此可以防止由引线边缘引起的对磁带的损坏, 并且可以使胶带的寿命更长。

    • In a refractive index measuring device (1) for measuring a refractive index of a solid sample (S), the solid sample (S) is closely attached to a prism (3) having a predetermined refractive index with a refractive index liquid (4) having a predetermined refractive index interposed therebetween. A scaled angle (light receiving member) (6) having a light receiving surface (6a) that receives first reflected light (R1), which is a part of light from a light source (2) and which is reflected by the prism (3), is provided. When the prism (3) is rotationally driven by a rotary table (rotational drive unit) (5) and an intensity of second reflected light (R2) detected by a detector (7) becomes lower than a predetermined value, the refractive index of the solid sample (S) is measured by using a position of the first reflected light (R1) on the light receiving surface (6a) of the scaled angle (6).
