摘要： In a recording and reproducing device for a magnetic disc, a swingable holder fixedly supports a first magnetic head, while a carriage supporting the holder swingably further supports a second magnetic head in a fixed manner. During a head-load time, the first and second magnetic heads are held in contact with the upper and lower surfaces of the magnetic disc at positions opposite to each other thereby to record or reproduce information to or from the magnetic disc. The recording and reproducing device of the above described construction is further improved by providing a damper device in a moving range of the holder so that the damper device can reduce impact when the first and second magnetic heads are brought into contact with the magnetic disc.

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： Herein disclosed is a retaining device for retaining a generally flat elongated part of a magnetic disc recording and reproducing apparatus. The lever retaining device is used to retain a disc eject lever in position on a bearing member of a disc player while preventing the same from slipping out of the position. Two guide pins are anchored upright on the bearing member of the disc player at a predetermined spacing from each other and have circumferential grooves near the heads thereof. Two slots are formed in the disc eject lever for allowing the two guide pins to extend therethrough when the eject lever is placed on the bearing member of the disc player. A generally flat elongated retainer member made of a thin elastic plate is formed at both its ends with engagement means for engagement with the circumferential grooves of the guide pins, when it is placed on the disc eject lever, to retain the disc eject lever. The engagement means of the retainer member includes a pair of keyhole-shaped holes having wider portions arranged at a greater spacing than that of the guide pins for allowing the guide pins to easily extend therethrough when the retainer member is slightly bent, and narrower portions arranged at a spacing substantially equal to that of the guide pins for snugly fitting therein the circumferential grooves of the guide pins when the retainer member is allowed to extend flatly on the disc eject lever.
摘要翻译：这里公开了一种用于保持磁盘记录和再现装置的大致平坦的细长部分的保持装置。杠杆保持装置用于将盘弹出杆保持在盘播放器的轴承构件上的适当位置，同时防止其从该位置滑出。两个引导销彼此以预定间隔直立地固定在盘播放机的轴承构件上，并且在其头部附近具有周向槽。当弹出杆放置在光盘播放机的轴承部件上时，两个狭槽形成在盘弹出杆中，用于允许两个引导销延伸穿过其中。由薄弹性板制成的大致平坦的细长的保持构件在其两端形成有接合装置，用于当其被放置在盘弹出杆上时与导向销的圆周槽接合以保持盘弹出杆。保持器构件的接合装置包括一对键孔，其具有布置成比导向销的间隔更大的间隔的较宽部分，用于当保持构件略微弯曲时允许引导销容易地延伸穿过其中，并且更窄的部分布置以与引导销的间隔大致相等的距离，以便当允许保持器构件平坦地延伸在盘弹出杆上时，将引导销的周向槽紧密配合。
