Abstract: A locking/unlocking means for cassettes, in particular those having swivel cover flaps, consists partially or completely of elastically deformable material and is pivotably mounted at two or more points. In the rest position of the locking/unlocking means, advantageously a swivel plate, an essentially tension-free arrangement is obtained by means of a supporting extension above the bearing axis, by actuation from outside, the said arrangement being converted in the operating state, without further spring elements, into a state of tension and into a position in which the supporting extension rests against the inside of an outer cassette wall and a reaction force corresponding to the actuating force is generated without any additional spring. Such a locking/unlocking means is suitable for cassettes of all types.

Abstract: A robotic hand has two sections disposed 90 degrees apart. One section has a bobbin core-engaging device for the purpose of lifting and handling the bobbin. This section also has a bobbin transfer means for removing the bobbin from the bobbin core engaging device. The second section of the robotic hand has a first fixed finger and a second movable finger. The fingers are used for clamping at least one lamination thickness of paper from the bobbin therebetween and holding it while the robotic hand is indexed to thread a processing machine with the paper from the bobbin. The second section also has a bobbin core removing means formed by the first fixed finger and a movable third finger. The first and third fingers cooperate for engaging the bobbin core and removing it from the machine after all of the paper has been removed therefrom.

Abstract: In a tape reel for use in a recording tape cartridge for winding a recording tape, there are formed a plurality of radial grooves on the upper face of a lower flange of the tape reel and projected ribs on the lower face corresponding to the grooves so that the wall thickness of the lower flange can be generally equal over the entire area to improve the flow of the plastic resin material during the molding process and to exhaust unwanted air.

Abstract: A videotape tape guide for guiding videotape in a videocassette. The videotape tape guide is comprised of an elongated cylinder having first and second open ends. A groove extends longitudinally from the first open end of the elongated cylinder to the second open end of the cylinder. The longitudinally extending groove allows the material required to form the tape guide to be reduced, thereby reducing the cost of the tape guide. Further, the groove allows firm seating in the videocassette to prevent rotation of the tape guide when positioned therein.

Abstract: Apparatus for inspection and repair of recording tape cassettes, particularly videotape cassettes, includes a base having a recess for stationarily receiving the cassette housing and an adjacent channel for receiving and maintaining the tape cover in open dispostion, and a tape advance mechanism having a pair of drive hubs engageable with the tape reels and a clutch release pin simultaneously engageable with the cassette's clutch mechanism to permit manual advance of the tape in either forward or reverse directions. A pair of spindles are mounted on the base in spaced relation to permit a medial extent of the tape to be withdrawn and trained sequentially about the spindles to maintain a portion of the tape transiently exposed for visual inspection during manual advance of the tape. The apparatus is particularly suited for locating and correcting twists, wrinkles, tears, cuts, etc. in the tape of the cassette.

Abstract: In order to prevent a tension control pad from being excited to the point of undergoing resonance, an arrangement modifies the normal resonance frequency of the pad upon a given amount of tension being developed in the tape against which the pad is applied. In the disclosed embodiment, the provision takes the form of a projection which engages a resilient leaf spring-like member upon a predetermined amount of flexure occuring in a manner which stiffens the arrangement and elevates its resonance frequency.

Abstract: A reel is formed of a plastic molded hub and side, disk-like flanges. The hub is made of thin-wall, cylindrical rings that are arranged end-to-end, and the flanges are made of two or more separate radial sections having radially oriented, overlapped edges that fasten together. Removable mechanical fasteners extend through passageways formed in the hub rings and through the flanges for fastening them together. The width of the reel may be varied by changing the number of rings. The diameters of the flanges may be varied by blocking off the outer portions of the mold in which the flask sections are molded to remove selected amounts of the peripheral portions of the sections for reducing the flange diameter. The hub rings and flange sections are interchangeable with like rings and sections for repair or reduced inventory purposes.
