    摘要： A double-sided emitting backlight unit has a first light-emitting surface for illuminating a first liquid crystal display panel disposed to face the first light-emitting surface, a second light-emitting surface provided parallel to the first light-emitting surface to illuminate a second liquid crystal display panel that is smaller than the first liquid crystal display panel and disposed to face the second light-emitting surface, and a peripheral surface extending between the first and second light-emitting surfaces and each groove having a light-receiving surface that receives light from a light source. The second light-emitting surface is a prism surface provided with a multiplicity of grooves extending parallel to the light-receiving surface and having a triangular section. The grooves in a part of the second light-emitting surface that corresponds to the second liquid crystal display panel in a direction perpendicular to the light-receiving surface are larger than the grooves in the rest of the second light-emitting surface in terms of at least one factor selected from among the following: the depth of the grooves; the angle between the second light-emitting surface and an inclined surface of each groove extending from the second light-emitting surface to the apex of the triangular section in a direction away from the light-receiving surface; and the number of grooves per unit length in the direction perpendicular to the light-receiving surface. With this configuration, the quantity of light per unit area emitted from a part of the first light-emitting surface corresponding to the second liquid crystal display panel is larger than that emitted from the rest of the first light-emitting surface.

    摘要： In a rotary head drum of a recording/reproduction apparatus, for smoothly holding a magnetic tape over a guide step provided on a lower drum to guide the magnetic tape, part of a chamfer formed in the guide step is formed as a large chamfer in which a chamfered amount is larger than that of the remaining part of the chamfer. With the provision of the large chamfer, even if the lower edge of the magnetic tape deviates from the guide step when the tape is wound over or unwound from the drum, damages of the magnetic tape can be prevented. Therefore, the position and attitude control of tape withdrawing members can be greatly simplified and the magnetic tape can always run stably while being restricted in its position by the guide step. In the process of machining a tape running surface on the drum, by increasing the feed distance of a blade in the part of the chamfer where the large chamfer is to be formed by chamfering the guide step with a large chamfered amount, in comparison with the feed distance set in the remaining part of the chamfer, the large chamfer and the small chamfer can be both machined at the same time, resulting in simplified machining steps.

    摘要翻译： 在记录/再现装置的旋转磁头鼓中，为了平滑地将磁带保持在设置在下磁鼓上的引导台上以引导磁带，形成在引导步骤中的倒角的一部分形成为大倒角，其中 倒角量大于倒角剩余部分的倒角量。 通过设置大倒角，即使当磁带从磁鼓卷绕或退绕时磁带的下边缘偏离引导步骤，也可以防止磁带的损坏。 因此，能够极大地简化卷取装置的位置和姿势控制，并且通过引导步骤限制在其位置，磁带总是可以稳定地运行。 在加工滚筒上的带子运行表面的过程中，通过在倒角部分中增加叶片的进给距离，通过以较大的倒角量倒角引导台阶，形成大倒角的部分，与 在倒角的剩余部分设置的进给距离，大倒角和小倒角可以同时加工，从而简化了加工步骤。

    摘要： A rotary magnetic recording and reproducing apparatus includes a stationary cylinder formed on a lower portion of an outer peripheral surface thereof with a guide lead for guiding a lower edge of a magnetic tape and defining a tape running face on an upper portion of the outer peripheral surface thereof, a first bulge portion formed on an upper edge portion of the tape running face of the stationary cylinder on a tape leaving side of the upper edge portion of the tape running face and a second bulge portion which is smaller in height than the first bulge portion and formed on the upper edge portion of the tape running face on the tape leaving side thereof and in the vicinity of the first bulge portion on a tape incoming side of the first bulge portion. The first bulge portion serves to relax shock or vibration of a magnetic tape leaving the magnetic head and the second bulge portion serves to improve "head-touch" of the magnetic tape.
