摘要： According to the structure of a conventional magnetic recording/reproducing apparatus, the loading and unloading of a cartridge are effected by pushing the cartridge into the apparatus manually against the biasing force of a plate spring which serves as a cartridge holding member, thus requiring a large force (about 0.5 to 1 Kgf) for the cartridge loading and unloading operation. In the magnetic recording/reproducing apparatus of the present invention, a slide member having retaining rollers is attached to a housing slidably and the retaining rollers are brought into engagement with engaging portions of a cartridge. In this state the slide member is allowed to slide to effect loading and unloading of the cartridge.
摘要翻译：根据传统的磁记录/重放装置的结构，通过将弹药筒作为药筒保持部件的弹簧的作用力手动地将药筒推入装置中来实现药盒的装载和卸载，因此需要大的力（约0.5至1 Kgf）用于墨盒装载和卸载操作。在本发明的磁记录/再现装置中，具有保持辊的滑动构件可滑动地附接到壳体，并且保持辊与盒的接合部分接合。在该状态下，允许滑动构件滑动以实现盒的装载和卸载。

摘要： A small-sized camera module in which an adhesive does not flow in side electrodes is provided. In the camera module according to the embodiment of the invention, the adhesive does not flow in concave portions thanks to a protection wall for covering top portions of the concave portions formed on a substrate. Accordingly, the side electrodes formed in the concave portions can be securely electrically connected to a contact or a drawing substrate. A lower portion of a holder can be disposed adjacent to the concave portions. Thus, the size of the substrate can be formed as small as possible, so it is possible to obtain the small-sized camera module.

摘要： According to the invention, there is provided a rotary head type magnetic recording/reproducing unit comprising a drum for receiving in close contact a magnetic tape on its periphery and a pair of magnetic heads arranged on the drum for running slantly on the magnetic tape for recording or reproduction of signals, wherein the span of contact of the drum's periphery and the magnetic tape is greater than that of a signal recording or reproducing operation on the magnetic tape by either of the magnetic heads. With such an arrangement, signal recording or reproducing operations of the unit can be conducted under a condition where the tape and the magnetic head are stably in contact with each other and therefore any distorted or deformed envelope waveforms may be eliminated.

摘要： A semiconductor light-emitting device which provides optically undistorted light includes a semiconductor light-emitting element and at least one optical element. The light emitting-element and the optical element are held in a resin which is transparent to light emitted from the light-emitting element so that light emitted from the light-emitting element travels to the optical element along an optical path entirely within the resin, but the light exits a portion of the optical element located outside of the resin.

摘要： A tape guide driving device for a rotating head type tape player having a mechanism for moving separately from each other a pinch roller and a tape guide. The rotating head type tape player includes a rotating head device, a capstan, and a tape feeding member that pulls a magnetic tape from an inserted cassette pack and moves it to a position at which it is wound on the rotating head device and to the position of the capstan provided on a chassis. A roller lever is provided that supports the pinch roller and moves the pinch roller from a position opposed to the inside of the tape within a cassette pack to the position close to the capstan, and a guide lever supports the tape guide and moves the tape guide from a position opposed to the inside of the tape within the cassette pack.During operation, the guide lever is pressed by the movement of the roller lever having the pinch roller which causes the tape guide to move. A guide section is formed in the form of an arch separated by a fixed distance to the rotation center of the roller lever, and a projection provided on the guide lever is made to contact the guide section by an elastic member. If the roller lever rotates, the positions of the guide lever and the tape guide are not changed.
