摘要： A magnetic recording device comprises a case (15, 16) that houses a disk drive motor (5) for rotating a recording medium (disk), a head (57) for reading information from and writing information onto the disk, and a head drive mechanism for driving the head. The case (15, 16) includes a cover (17) that may close a cartridge slot (18). When the cover (17) is leaned forward to open the cartridge slot (18), its upper surface becomes substantially at the same level as a frame plate on which the disk drive motor (5) and the head drive are mounted.

摘要： When a head (34b) mounted on a lower head arm (32b) is in a standby position permitting no access to a magnetic recording disk (13), the head arm (32b) is housed in an opening (37) formed in a frame plate (3). Thus, the head arm and another (upper) head arm 32a may maintain a predetermined distance even in a card-type magnetic recording device of small thickness. An electromagnetic shield material is adhered to the opening to protect the heads (34a, 34b)

摘要： A card type electronic device comprising a case (4) including a rectangular frame (5) and two covers (6, 7) covering the upper and lower faces of the frame (5). At the longer side edge portions of the covers (6, 7), generally U-shaped retaining members (11a, 11b) are formed by bending a partially protruded tongue (10) at its leading end toward the other covers (6, 7) and further at its leading end to the inner peripheral side. In the side face of the frame (5), on the other hand, there are formed recesses (19a, 19b) for guiding the retaining members (11a, 11b) vertically, and retaining portions (20a, 20b) for engaging when the retaining members (11a, 11b) fitted in those recesses slide longitudinally of the case (4).

摘要： A magnetic recording device is covered with a case (15, 16). A cartridge slot (18) for receiving a cartridge containing a recording disk is formed in the rear end of the case (15, 16). A frame plate (19) included in the case is drawn to form a first recess and a second recess. A disk drive motor (5) is fitted in the first recess, while a head drive motor (16) for driving a read/write head (17) with respect to the disk is fitted in the second recess.
