摘要:
Rather than engage the grooves (38) of a cartridge's splined hub by means of fingers attached to a reel motor shaft, the present invention uses a mechanical coupler (10) mounted on the motor shaft which contacts the spline lands (36) at two places and locks the mechanical coupler (10) position by insertion of a spring loaded tongue (26) into one of the grooves (55) of the spline. This groove (55) is angularly located midway between the lands (44, 46) which contact the mechanical coupler (10), effecting a ''three point'' engagement of the mechanical coupler (10) with the hub (34). The land contacting surfaces (16, 18) and the tongue (26) are chamfered (20, 22, 30) to facilitate engaging the hub (34) for slight off-axial misalignment of the hub (34) and mechanical coupler (10). The spring loaded tongue (26) forces the spline contacting surfaces (16, 18) of the mechanical coupler (10) into a ''zero clearance'' fit with the contacted lands (36) of the spline, providing an intimate and backflash free connection between the hub (34) and driving motor.

Die Neuerung betrifft Wickelkerne (1) zum Aufschieben auf eine Wickelwelle, wobei jeder Wickelkern (1) entlang seinem Innendurchmesser (2') benachbart der zentralen Bohrung (16) alternierend in beide axiale Richtungen weisende Kerben (3,3') besitzt. Jede Kerbe (3,3') endet in einer vorzugsweise abgeschrägten Stufe (4), welche ungefähr in der geometrischen Mitte (5) des Wickelkerns (1) beginnt. Federbelastete Spannelemente (6,6',7,8) am Umfang (9) jedes einzelwickelkörpers sind mit Vorsprüngen in radialer Richtung versehen, welche in axialer Richtung rastbar mit den Kerben (3,3') der Wickelkerne (1) zusammenwirken.

A spool mounting apparatus, particularly suitable for automatic, unbuffered tape transport systems, permits a reduction in the handling of spools during loading sequences. A spool inserted through an opening (12) into a cavity (20) within a housing (10), is guided into a preliminary position by a detent pin (26). The opening possesses a spring biassed closure member (13), which is mechanically linked to a free running disc member (40) within the cavity (20) situated opposite a shaped cylindrical hub (30) over which the spool may locate. Motion of the spring biassed closure member (13) towards a closed position effects displacement of the free running disc member (40) towards the hub (30), thereby clamping the spool disposed therebetween. Subsequent rotation applied to the hub (30) is therefore transferred to the clamped spool and the free running member (40).

In the reel of a magnetic tape cartridge, in which the reel with magnetic tape wound thereon is rotatably housed in a cartridge case, a magnetic metal plate is molded integrally on a reel bottom surface by insert molding. The metal plate is formed into an annular shape having a central hole. In a reel bottom wall closing the central hole of the metal plate with resin injected from a gate at the center of the central hole of the metal plate when the insert molding is performed, a recess is formed between a gate trace at the center portion of the bottom wall and an inner peripheral surface of the central hole of the metal plate.
摘要:
A supply reel hub (16) for use on a computer tape drive (10) for assuring that a supply reel (12) is squarely locked down and properly aligned on the computer tape drive (10). The supply hub (16) comprises a locking means in the form of three L-shaped feet (20) for locking the supply reel (12) securely in place, a plurality of spaced apart sensing means (52) and a plurality of signalling means (56,58,60) which sense and signal to a controller (142) whether each of the three L-shaped feet (20) of the locking means (64,66,68) are properly in position. A centering knob (28) positioned on the top of the supply hub (16) has been provided so that a supply reel (12) may be easily centered over the supply hub (16). A groove is positioned on the base of the supply hub (16) to allow a write enable tab to slip off of the supply hub (16) and not hang up on the centering knob (28). Additional sensing means (62,78,86) are provided for sensing whether there is a write enable ring on the supply reel (12). Means for releasably attaching the shaft (24) of the drive motor (27) to the hub base which reduces tape edge damage is also provided. The positioning of the L-shaped feet (20) is checked on loading and unloading and in the event of improper positioning of the L-shaped feet (20), an error message is displayed on the computer tape drive (10) and may also be displayed on the computer. A method of assuring the locking and unlocking of the hub (16) is also disclosed.

Ein Blockagevorrichtung (10) der Bandspulennabe (20) in Bezug auf eine rotierende Welle (16) wird so realisiert, daß die Spulennabe (20). wenn sie einmal auf einer Stützbasis (19) in Position ist, blockiert wird, und in jedem Fall ein zufälliges Abspulen verhindert wird. Durch eine solche Vorrichtung (10) wird außerdem die Selbsteinstellung der Nabe (20) in Bezug auf die rotierende Welle (16) der Auf- und Abspulung garantiert.
