专利说明:
The invention relates to the accumulation of information, namely to tape cassettes. A known tape cassette containing the feed and take-up coils. In a known cassette in the recording and reproducing process, the rewinding of the magnetic tape from the supply reel to the receiving SP is provided. However, using a known cassette may damage the magnetic tape due to its spontaneous unwinding. Also known is a cassette for magnetic tape containing a feed coil mounted with the possibility of axial movement and made with a core having longitudinal grooves in its central opening and with a lower cheek having a concentric butt-shaped toothed crown interlocked with another face toothed crown fixed on the lower cheek of the casing, made with the first insertion hole, placed against the ring gear of the lower cheek of the take-up coil, with the second insertion hole placed against the brake element one with a round hole in which an annular protrusion of the core of the supply coil is located, and with a shaft rigidly fixed by means of a screw having a head and installed in the central hole of the core of the receiving cathode, whose diameter is smaller than the diameter of the core of the supply coil, and a plate spring mounted on the upper cheek of the casing and the interface with concentric lugs of the feed and receiver coils. This cassette ensures the prevention of damage to the magnetic tape due to its spontaneous razmashansheni 121. The disadvantage of such a cassette is the considerable complexity of its service. This is due to the complexity of the installation process of the cassette in the cassette receiver of the tape mechanism. The purpose of the invention is to simplify the use of a cassette for a magnetic tape. The aim is achieved by the fact that in a cassette for a magnetic tape containing a feed coil mounted with the possibility of axial movement and made with a core. 1 99 2 with longitudinal grooves in its central hole, and with the lower cheek, having a concentric-centered face gear, coupled with another face gear, mounted on the lower cheek of the casing, made with the first insertion hole, placed against the gear of the lower cheek of the reception coil, with a second insertion hole placed against the brake element, with a round hole in which the annular protrusion of the feed coil core is located, and with the shaft rigidly fixed by means of a screw, having head, and installed in the center hole of the core of the receiving coil, the diameter of which is less than the diameter of the core of the supply coil, the leaf spring mounted on the upper cheek casing and mated with concentric projections of the cores of the supply and reception coils, the bottom cheek of the casing is made with a circular cylindrical recess, the head the screw is fitted with a guide, and the teeth of the lower cheek of the receiving coil have bevels on its teeth, with the screw head protrusion located concentrically inside A round cylindrical recess in the lower cheek of the housing The proposed cassette, due to the fact that the lower cheek of the housing is made with a circular cylindrical recess, the screw head is provided with a guide protrusion, and the toothed rim of the lower cheek of the pickup coil has bevels on its teeth, which greatly simplifies the process of its maintenance. FIG. 1 and 2 show different views of one of the possible variants of the proposed tape cassette; FIG. 3 is a scan of the gear rim of the lower cheek receiving coil in FIG. 4 - screw and shaft. The cassette contains a casing 1 in which the feed coil 2 is located, mounted with the possibility of axial movement. The feed coil 2 is made with a core 3 having longitudinal grooves 4 in its central hole, and with a lower cheek 5 having a concentric toothed rim 6 which is concentric with the other interlocking with the other one toothed rim 7 fixed to the bottom 31 her cheek 8 casing 1. The bottom cheek 8 of the casing 1 is made with the first insertion hole 9 located against the ring gear 10 of the lower cheek 11 of the receiving coil 12, with the second insertion hole 13 placed against the brake element (not shown), and with a round hole 14 in which the annular protrusion 15 is located core 3 of the supply coil 2. The lower cheek 8 of the casing 1 is also made with the shaft 16, rigidly fixed by means of a screw 17 having a head 18, and installed in the central hole of the core 19 of the receiving coil 12, whose diameter is smaller than the diameter of the heart 3 and the supply reel 2. The cassette contains, in addition, a leaf spring 20 fixed on the upper cheek 21 of the casing 1 and conjugated with concentric protrusions 22 and 23 by the core 3 and 19 of the feed 2 and the receiving 12 coils on the side of their upper cheeks 24 and 25. In the proposed cassette, the lower cheek 8 of the casing 1 is made with a circular cylindrical recess 26, and the head 18 of the screw 17 is provided with a guide protrusion 27. The guide protrusion 27 of the head 18 of the screw 17 is located concentrically inside the circular cylindrical recess 26 of the lower cheek 8 of the casing 1. In addition, the gear rim 10 of the lower cheek 11 of the receiving coil 12 has bevels 28 on its tooth The magnetic tape 29 is arranged in rolls on the cores 3 and 19 of the feed and take-up coils 2 and 12. The feed coil 2 is mounted in such a way that the protrusions of the winding and rewinding element 20 can enter the longitudinal grooves 4 of the central hole of its core 3. . When the tape is stored and recorded and played back, the following happens on it. If the cassette is out of the cassette receiver of the tape mechanism, the face gear 6 of the lower jaw 5 of the feeding reel 2 is engaged with the other face gear 7, 994 which prevents the spontaneous unwinding of the magnetic tape 29. When installing the proposed cassette into the cassette receiver of the tape-forming mechanism, the winding and rewinding element 30 enters the central opening of the core 3 of the feeding reel, providing axial movement last. As a result, the mechanical gear rim 6 of the lower cheek 5 of the supply coil 2 and the other mechanical gear rim 7 is disengaged. In addition, when the proposed cassette is installed in the cassette receiver, the driving gear of the rotational section of the tape-shaped melander passes through the first inlet 9 of the lower cheek 8 of the casing one and engages a notched crown 10 of the lower cheek 11 of the receiving coil 12. In this case, the bevels 28 on the teeth of the toothed crown 10 of the lower cheek 11 of the receiving coil 12 ensure smooth coupling with the driving gear of the rotation unit of the tape mechanism. When installing the proposed cassette in the cassette receiver the protrusion 27 of the head 18 of the screw 17 is located in the centering hole of the sleeve-shaped retainer of the tape mechanism, which enters the circular cylindrical recess 26 of the lower cheek 8 of the casing 1, which ensures precise installation of the proposed cassette into the tape cassette receiver, In the process of recording and reproducing, the drive gear of the rotation unit of the tape mechanism provides the rotation of the receiving coil 12, which transfers the magnetic tape 29 onto it from the feeding coil 2. The tension of the magnetic tape 29 is provided by the winding and rewinding element 30. The use of the invention in comparison with the base object allows to greatly simplify the process of servicing the tape cassette.
