摘要： A tape appliance includes first and second tape head modules, and a guide surface with first and second slots. The guide surface is configured such that the as the tape moves in first and reverse directions of longitudinal tape travel, the tape wraps about the guide surface, and at least two non-overlapping wrap positions of the tape engage the first slot, and at least one wrap position of the tape engages the second slot. When the tape travel is in the first longitudinal direction, the first and second tape head modules are positioned within the first and second slots, respectively, such that the first tape head module is the leading module. When the tape travel is in the reverse longitudinal direction, the first and second tape head modules are positioned within the first and second slots, respectively, such that the first tape head module remains the leading module.

摘要： Disclosed is a reel hub latch assembly used in magnetic tape recording/reproducing apparatus. The disclosed reel latch assembly accurately locates a reel on a hub and prevents slippage between the hub and reel when the reel is rotated to transport tape onto and off of the reel. The reel mounting hub has an annular groove containing an annular, U-shaped radial spring at the bottom of the groove. The radial spring has a plurality of circumferentially spaced fingers. An annular garter spring is located in the groove overlying the circumferentially spaced fingers of the radial spring. A magnetic tape reel, mounted on the hub, has a conical inner wall which is engaged by the garter spring. Preferably, the engaging portions of the spring are shaped to conform to the shape of the conical wall to reduce stresses on the reel.

摘要： A hub setting device for a hub onto which a magnetic tape is wound with which the hub can easily be attached to and removed from a rotary shaft with substantially no play between the hub and shaft when engaged. A divided ring is retained in a recess formed in a boss portion of the shaft, and the ring is urged radially outwardly by an elastic member such as a pair of elastic tubular members. An elastic retention member is fitted around the divided ring, received completely within a recess formed around the outer circumferential surface of the ring.

摘要： Coaxially disposed tape reels are driven independently of each other by motors located inside coaxial hubs on which the reels are held. The mechanisms for loading and unloading the reels include arc-segment-shaped levers pivoted at one end on rings and actuated at the other end in the space between the drive motors and the hub shells to push out their mid portions to provide, in sequence, clamping of the lower reel, provision of a support for the upper reel and clamping of the upper reel, with retraction of the levers in the reverse sequence enabling removal first of the top reel and then of the bottom reel. A grip knob at the top which can be turned relative to one or both of the hubs serves to actuate this mechanism.

摘要： A hollow-cylindrical member, such as a reel, is releasably retained on a rotatable hub against forces tending to loosen the reel. To this end, a plurality of locking keys are inserted into corresponding axial slots in the reel at the inside thereof. These locking keys are first driven up corresponding ramps on the hub into engagement with the inside of the reel at corresponding slots. After such engagement, and during rotation of the hub and reel, the locking keys are continously biased or further urged into their corresponding slots in order to inhibit any looseness between the releasably retained reel and the rotating hub. By way of example, tape reels of large size and mass may thus be securely retained against strong inertial forces occasioned particularly during rapid reversals of the reel rotation as occurring, for instance, in modern instrumentation tape recording and data processing machines.

摘要： An apparatus for driving a replaceable reel of magnetic tape is disclosed. The apparatus comprises a magnetic clamp for holding the reel to a cup-shaped driving member. The cup-shaped driving member carries a doughnut-shaped magnet and is provided with an integral center shunt member which extends into the center of the reel when the reel is positioned in driving engagement. The reel is provided with a central opening, and a circular metal plate is attached to the bottom surface of the reel hub to be attracted by the doughnut-shaped magnet. By extending the center pole piece a predetermined distance above the plane of the doughtnut-shaped magnet, the extended center pole piece provides an easy path for the flux as the members are being separated, since a relatively small air gap is maintained between the extended center pole and the central opening of the disk. At the point where the members separate, the strength of the magnetic field is not sufficient to adversely affect the information stored on the tape which is wound on the reel. In prior art arrangements, as the reel was being removed from the driving arrangement, the air gap which existed between the shunt member and a shorter center pole would increase to the point where the magnetic field would no longer be shunted through the metal shunt. The strength of the resulting stray magnetic flux was sufficient to adversely affect the information stored on the magnetic tape that was wound on the reel.

摘要： A rotatable housing for a magnetic clutch contains a circumferential mounting portion thereon for receiving a rotary member, as, for example, a spool of recording tape. The mounting portion defines a surface therearound which contains detents for axially locating the rotary member on the latter surface. In a preferred embodiment, the detents are arranged in clusters about the circumference of the mounting surface, each cluster including at least two detents axially spaced, each detent defining a circumferentially extending protuberance on the mounting surface. In an alternate preferred embodiment, the mounting surface also includes a drive tang for limiting movement of the rotary member to one direction only, the drive tang defining an axially extending protuberance on the mounting surface.

摘要： Supply and take-up reels are mounted above a horizontal base for selective powered rotation about respective vertical axes. Vertical guide surfaces and a cover panel define an air tight continuous flowpath extending between the peripheries of the reels past a read/write head. A blower mounted in a hood structure beneath the base sucks air through the flowpath and through a perforated center spool of the take-up reel. A river of air thus pulls and guides the free end portion of the magnetic tape from the supply reel to the take-up reel as the supply reel is rotated by a drive motor to unwind the tape therefrom. The supply hub is adapted to automatically center the supply reel thereon. The supply hub further includes a plurality of annularly spaced reel engaging pawls mounted in, and normally retracted into the hub, and an over-center actuating means for selectively extending the pawls through differential rotation of a pair of separate rotors included in the hub.
