摘要： A signal recording/reproducing apparatus for use with a tape cassette comprises a cylinder assembly having an outer peripheral surface. The cylinder assembly has mounted thereon heads for recording and reproducing a signal on and from a magnetic tape in the tape cassette, respectively, and a lead formed on the outer peripheral surface of the cylinder assembly so as to helically extend, to define a running path of the magnetic tape on the outer peripheral surface of the cylinder assembly. A pair guides guide the tape so that the tape is helically wound over a predetermined angular extent along the lead upon the recording/reproducing of the signal. The pair of tape guides are located and oriented in their predetermined positions such that the tape guides impart a force to the tape to press the tape onto the lead during recording and reproduction thereby to permit the tape to move along the lead.

摘要： The speed of a disc handling operation by a disc apparatus having disc changer capability is significantly increased and, at the same time, the disc handling operation is performed with stability. In the disc apparatus according to this invention, a plurality of reproducing units loaded with discs are moved independently and disc reproduction is started by returning the reproducing units to their dedicated positions. Simultaneous returning of the plurality of reproducing units is prevented and each reproducing unit moves for refuge while reproducing the disc. This novel setup significantly shortens the time for moving the reproducing units for disc reproduction. When continuously reproducing a plurality of discs accommodated in proximity, the plurality of reproducing units are moved in a stacked state rather than independently. This also contributes to a significant reduction of the time in the disc handling operation. Further, when raising the lower reproducing unit in the stack, it is moved together with the upper reproducing unit; when raising the upper reproducing unit, it is separated from the lower reproducing unit for independent movement. This prevents the reproducing units from colliding against each other. The novel constitution significantly enhances ease of use of the disc apparatus.
摘要翻译：通过具有换碟机能力的盘装置的盘处理操作的速度显着增加，并且同时执行盘处理操作。在根据本发明的光盘装置中，装载有光盘的多个再现单元被独立地移动，并且通过使再现单元返回到其专用位置来开始盘再现。防止多个再现单元的同时返回，并且每个再现单元在再现盘时移动避难。这种新颖的设置显着地缩短了用于盘再现的移动再现单元的时间。当连续地再现容纳在接近的多个盘时，多个再现单元以堆叠状态而不是独立地移动。这也有助于在盘处理操作中显着减少时间。此外，当升起堆叠中的下再现单元时，它与上再现单元一起移动; 当升起上再现单元时，它与下再现单元分离以进行独立运动。这防止再现单元相互碰撞。该新颖的构造显着提高了盘装置的易用性。

摘要： The invention provides an optical disc apparatus which restricts an operation sound generated from an objective lens driving portion of an optical pickup and has a reduce sound, in an optical disc apparatus, in particular, an optical disc apparatus installing a microphone for recording an external voice therein. Coils (107, 108), a magnet (109) and opposing surfaces of a yoke (110) are respectively arranged at substantially point symmetrical positions with respect to an optical axis (111) of an objective lens (103) in a state in which no electric current is applied, the yoke (110) and a unit base (117) are connected via a spring member (118), and the unit base (117) is mounted to a casing (120). In this case, the spring member (118) is connected at a position (121) forward apart from the objective lens (103) with respect to the yoke (110), and is formed so as to have at least a deformation freedom in a direction of the optical axis of the objective lens (103). The casing (120) is made in a closed structure surrounding a space in which the unit base (117), a lens holder (106), the yoke (110) and the magnet (109) are arranged, except a surface opposing to a disc-like recording medium (104).
