摘要： A brighter and whiter reflector provides high reflection efficiency over a wide range of angles. An indenting tool is pressed against the surface of a matrix base material; the pressing operation is repeated while changing the position of the indenting tool on the surface of the base material for the matrix to successively form many pits, the inner surfaces of which are shaped like partial spheres, on the mold surface of the matrix base material so as to provide it as the matrix for forming the reflector. Then, a transfer mold having a mold surface which has a reversed pattern of the pits and projections of the mold surface of the matrix is made, and the mold surface of the transfer mold is transferred to the surface of the base material for the reflector to provide a reflector (1). Pits (4) of the reflector (1) are formed so that the depths the pits (4) range from 0.1 &mgr;m to 3 &mgr;m, the tilt angles of the inner surfaces of the pits (4) are distributed in the range of −18 degrees to +18 degrees, and the pitches between adjoining pits (4) range from 5 &mgr;m to 50 &mgr;m. A reflection type liquid crystal display device in accordance with the present invention is equipped with the reflector (1).

摘要： In the conventionl magnetic recording/regenerating apparatus,loading/unloading of a cartridge has been manually carried out, thus requiring a large force (about 1.5 to 3 kgf) for these operations by a spring force of a leaf spring, and making it difficult to ensure loading of the cartridge in the magnetic recording/regenerating apparatus. In the magnetic recording/regenerating apparatus of the invention, the portion between one end side and the other side of the linking member is rotatably supported on the bottom plate of the enclosure, and the supporting point as a fulcrum, the distance between the fulcrum and an end connecting the second sliding member is made smaller than the distance between the fulcrum and the other end connecting the first sliding member.

摘要： Disclosed is a magnetic recording-reproducing device in which an engagement portion of a cartridge is locked by a locking portion of a first slide member; therefore as first and second slide members and slide, the cartridge also slides to be loaded and unloaded. The loading and unloading of the cartridge, therefore, can easily be accomplished with extremely little force.

摘要： A first and second rotary members are supported on a holder 3 secured to a main chassis of disk drive apparatus. The first rotary member includes a detecting portion. The second rotary member includes a contact portion that moves in and out of the insertion path of a disk cartridge to be inserted into the holder. When the disk cartridge is being inserted, an opening-and-closing pin opens the shutter of the disk. Through the detecting portion, the opening shutter rotates the first rotary member, which then rotates the second rotary member to thereby move the contact portion of the second rotary member out of the insertion path of the disk cartridge, allowing the disk cartridge to be inserted. If the shutter fails to open when the disk cartridge is being inserted, the contact portion of the second rotary member will remain in the insertion path and block the insertion of the disk cartridge.

摘要： A push-lock device has a damper mechanism 9 which includes a strip body 17; protruding portions 14, 16; a protruding portion 26; and a rubber ring 23. The strip body 17 is arranged in the moving direction of the sliding body 4 housed in the case 2 and has a meandering groove 22 formed therein. The protruding portions 14, 16 support rotatably the ends of the strip body 17. The protruding portion 26 is arranged to the sliding body 4 and engages to the meandering groove 22. The rubber ring 23 is arranged between the base 2b of the case 2 and one end of the strip body 17.
