Abstract: A dual switch for selective removal of a recording medium from a compound device is so exactly sized and shaped that are exact switching action may be assured. Two switches are on a base plate, and a button is capable of selectively actuating either switch to take a recording medium out of the slot. The button has resilient member responsive to removal of pressure from the button for returning to its original position. The button can be of seesaw, slide or rotary type.

Abstract: The invention provides a disk device that is excellent in strength, an easy installation and adjustment performed in the manufacturing process, an easy maintenance and repair work performed, and the safety during repair and maintenance work further achieving a cost reduction. A clamper 41 is provided and a board 12 having an area in which at least the irradiation range of laser light emitted by an optical pickup is covered is fixed to a frame 11 that constitutes a disk device 1 by screwing or the like, thereby improving the strength, safety, and workability of the disk device 1.

Abstract: The present invention provides ease of attachment and adjustment in manufacturing steps and ease of maintenance, repair work, and safety, and eliminate necessity for jig substrate for adjustment so as to reduce cost. In a disk device 1 provided with a pickup unit and a traverse unit, wherein a pickup substrate and the like is electrically connected to the control substrate 12 after the control substrate 12 is placed at the top of the disk device, the pickup unit is adjusted after a short-circuit between an anode electrode and cathode electrode of a laser light-emitting element provided in the pickup unit is disconnected, and the operation of the pickup unit in the adjusting step is controlled using the control substrate 12. After the pickup unit is adjusted, the control substrate 12 is attached to the top end of side walls on both sides of a frame 11 and placed at the top of the disk device 1.

Abstract: To provide a dual switch for selective removal of a recording medium from a compound device which is so exactly sized and shaped that the exact switching action may be assured, it comprises two switching means on a base plate and a button capable of selectively actuating either switching means to take a recording medium out of the slot. The button has resilient means responsive to removal of pressure from the button for returning to its original position. The button can be of seesaw, slide or rotary type.
