Abstract

A cartridge for either a disk or a reel of tape for a magnetic recorder/reproducer may be held in place and driven by the mechanism shown in the figure. The mechanism accepts the cartridge 1 that is pushed in line with its clutch drive spindle axis 2. A spring-urged movable elevator plate 3 maintains a plane perpendicular to the spindle axis 2, and holds and positions the cartridge 1 by coaction with retaining fingers 4. As the cartridge is moved against the elevator plate 3, it is guided and positioned into place. Guide pins (not shown) can be used to accurately position the cartridge relative to the drive.

Cartridge-Handling Station

A cartridge for either a disk or a reel of tape for a magnetic recorder/reproducer may be held in place and driven by the mechanism shown in the figure. The mechanism accepts the cartridge 1 that is pushed in line with its clutch drive spindle axis 2. A spring-urged movable elevator plate 3 maintains a plane perpendicular to the spindle axis 2, and holds and positions the cartridge 1 by coaction with retaining fingers 4. As the cartridge is moved against the elevator plate 3, it is guided and positioned into place. Guide pins (not shown) can be used to accurately position the cartridge relative to the drive. Movement of the elevator plate 3 by the insertion of the cartridge onto the drive clutch 5 causes a drive plate 6 to be lifted away from the elevator plate 3, thereby disengaging the brake teeth 7 to allow rotation of the drive plate 6.

The drive plate 6 could contain either a disk having a magnetic surface or it might be part of a tape reel positioned within the cartridge. The drive plate is rotated through the drive clutch 5 and centered by a push rod 8 extending through bearings to a drive shaft pulley 9. Separation or removal of the cartridge from the station is initiated by action of a trip button 10 which moves a disk 11 against projection 12 of the retaining fingers 4. As the trip button 10 is moved upwards, springs 13 are compressed and retaining fingers 4 are moved outward, thereby releasing the cartridge. The elevator plat...
