Abstract: PURPOSE: To obtain a disk drive enclosure structure where a special form whose draft is zero is used in a die casting process. CONSTITUTION: A data storage disk drive 10 includes a spindle, which supports plural disks on the surface of a magnetic disk which are rotated around a common shaft and form a spindle assembly 18, and a rotary actuator which supports plural magnetic transducers on the surface of each disk. The disk drive includes a die cast disk drive enclosure structure 12 including the surface to which a spindle motor shaft and an actuator bearing shaft are set and where a predeterminate draft is zero. The enclosure structure includes a base cast member 14, which holds an electric connector arranged on the outside, and a cover cast member 16. The disk drive includes an electric passage from a flexible circuit to a comb-shaped part of the actuator. The disk drive includes a tubular chemical air filter arranged in a groove for diffusion integrated with the cover as one body.

Abstract: A data storage disk drive is provided with a spindle which supports a plurality of disks having at least one magnetic disk surface to form a spindle assembly for rotation of the disk surfaces about a common axis and a rotary actuator which supports magnetic transducers for movement in unison about respective disk surfaces. The disk drive includes a disk drive enclosure having die-cast generated predetermined zero draft geometries for mounting the spindle motor shaft and the actuator bearing shaft. The enclosure includes a base casting and a cover casting, each casting including structure for locating and retaining electrical connectors used for connecting to a planar electronics card located outside the drive enclosure. The disk drive includes an effective and easily manufacturable electrical path from a flex circuit to an actuator comb. The disk drive includes a tubular chemical breather filter arranged with integral housing and diffusion channels formed in the cover casting.

Abstract: A shared document feed station includes a common drive mechanism for normally advancing a receipt tape through a receipt tape zone and for selective operation to advance an alternative document through an alternative document zone. Document detectors sense the presence of a document in the alternative document zone and function to inhibit the drive mechanism from advancing the receipt tape while enabling the advance of the alternative document.

Abstract: A data storage disk drive is provided with a spindle 42 which supports a plurality of disks 110 for rotation about a common axis, and a rotary actuator 20 which supports magnetic transducers for movement in unison across respective disk surfaces. The disk drive includes a disk drive enclosure having die-cast generated predetermined zero draft registration surfaces 30 - 40 for mounting the spindle motor shaft 42 and the actuator bearing shaft 44 and possibly magnet assemblies 46, 48. The enclosure includes a base casting 14 and a cover casting 16, each casting including structure (figs. 7 - 9) for locating and retaining electrical connectors used for connecting to a planar electronics card (90) located outside the drive enclosure. The disk drive includes an effective and easily manufacturable electrical path from a flex circuit to an actuator comb (figs. 11 - 13). The disk drive also includes a tubular, at least partly electrostatic, chemical breather filter (56) arranged with integral housing and diffusion channels (58) formed in the cover casting (figs. 14 - 24).

Abstract: A paper tape supply for drawing paper tape off a supply roll including a flatted pressure roll adapted to have a nip with a feed roll on peripheral surfaces of the pressure roll exclusive of its flat, to grip the tape in the nip of the rolls. A trip lever holds the pressure roll with its flat opposite the feed roll to release the paper tape, and a leaf spring acts on the pressure roll and tends to move it against the trip lever. As an outgoing loop of tape from the rolls shortens, it releases the trip lever with respect to the pressure roll to allow the leaf spring to rotate the pressure roll into its nipped relation with the feed roll to draw the tape off the supply roll and lengthen the outgoing loop of the tape.
