TH6965B - Cassette Tape - Google Patents

Abstract

Cassette tapes are suitable for use with 8 mm tape recorders for recording. and/or reusing video and audio signals It consists of an opening for inserting a light through formed on the lower surface of the cassette near the front surface of the cassette located between the pay and receiving reels that are side by side in the cassette. Apertures formed through the walls on both sides of the cassette to allow light from the emitter to pass through, provided that the emitter is inserted in the through opening. and a translucent part molded into the upper surface of the cassette. In order to be able to see the pay and the receiving reels, here the translucent part forms at least part of the wall that surrounds the opening for the light to pass through. It is molded into the same part as the translucent part of the top surface of the cassette. Therefore, it is easy to produce cassette tapes. that can prevent dust or the like And will prevent rust on the magnetic tape as well.

Claims (2)

1. Tape cassette types that have the upper and lower cassette cassettes, each of which are opaque. And made to combine together to form a front wall Back and sides The upper inverted has an upper surface and the lower inverted surface has the bottom surface. And the implant for the light emitting element placed between A tape-shaped medium with a light transmission component wrapped around the supply reel and the receiver reel between the upper and lower cassette. And surround the part for inserting the light emitting parts And an aperture that passes through at least one of the side walls. To interrupt the insertion of the transverse light-emitting element with the tape medium, so that when the cassette is inserted into the recording unit and for new applications The light-emitting element is inserted into the insertion part, and the light-receiving element is placed outside the aperture. To provide a light trajectory between the center and to allow pre-determined detection of the tape medium, the cassette consists of: a transparent compartment attached to the top surface of the upper cassette. Therefore, the pay roll will be seen and received through the transparent channel. Some cylindrical parts opposite A pair of opaque upper tails formed into one piece with the upper cassette. And the cylindrical section with a notch at the bottom, which forms together as a single piece with the lower case The cylindrical top and bottom allow the shape and size to match knees to each other. When making the top cassette with the lower one to be connected together The transparent part, which is molded into one piece with a transparent channel and positioned between some cylindrical sections. Therefore, the transparent section with the top and bottom cylindrical sections together to form the top and bottom sealed enclosures. The parts for inserting the light emitting parts to make the upper and lower cassettes connect together. The transparent part is aligned with the aperture to allow light from the light-emitting part to pass through the transparent part and the aperture to the receiving element. 2. Tape cassette according to claim 1, here the transparent parts are connected into one piece with a transparent compartment through one or more spines. Which lies beneath the surface of the upper cassette
