摘要： An electrical contact (1) includes a medial portion (10), two upper arm portions (11), and a lower solder portion (12). The medial portion includes two sidewalls (100), and an engaging portion (101) below one sidewall. The solder portion depends from the engaging portion. Each arm portion extends from a top of a respective sidewall, and is deflectable from a rest position to a deflected position by a corresponding horizontally actuatable mating pin (2). Each arm portion includes a top contact portion (110), and a guiding portion (111) extending obliquely from an end of the contact portion. The guiding portion has an inner convex side (1112) and a bottom edge (1110). The contact portion also has an inner convex side (1101). As each arm portion is deflected from the rest position to the deflected position, the pin contacts a contact section of the arm portion located above the bottom edge.

摘要： A photosensor block for use with a zero track sensor of a disk drive unit or the like wherein adjustment of the position of a photosensor can be effected simply with accuracy. In the photosensor block, a photosensor forms a side of a deformable parallelepiped and is mounted on a mounting member having a pair of parallel elastic members which form a pair of opposing sides of the parallelepiped. An interconnecting portion of the mounting member between the elastic members is secured either to the photosensor or to a base member which is mounted on a stationary section of the unit and forms the remaining side of the parallelepiped. Opposite ends of the elastic members are removably connected to the other of the photosensor and the base member. An adjusting member is adjustably mounted on the base member for pressing against a side face of one of the elastic members for fine adjustment of the position of the photosensor.

摘要： A recording and reproducing apparatus has a loading mechanism for loading a disk cartridge, which is inserted in a cartridge holder, between an eject position and an operative load position. The loading mechanism has a load lever which pivots the holder to the load position when the disk cartridge is inserted to push against a portion of a cam plate and move it rearwardly in the apparatus. The apparatus has only one tension spring between the load lever, which is angularly movable between an eject position and a load position, and the cam plate which can bear on the cartridge. The tension spring angularly biases the load lever toward the load position and biases the cam plate toward an opening through which the cartridge is inserted.

摘要： An improved rotary encoder where trackability and durability is an improved and a wider installation field is no longer necessary. Particularly, a rotary encoder and a rotary driver are separated. In the rotary encoder, a rotor is provided and its circumference is provided with a reflection surface and other surface resulting in reflectivity difference. Concave and convex parts are formed at the circumference of rotor and the upper surface of convex part providing the reflecting surface. A light emitting part and the light receiving part are arranged closely so that their end surfaces placed in contact through a flat contact surface, and thereby a sufficient output voltage can be obtained as compared with the other end surface structure. Moreover, the light emitting part and light receiving part are arranged adjacent circumference of the, and rotor, and adequate space is formed between the rotor and holding means for assuring free rotation under the no contact condition.
