    The group of inventions relates to the accumulation of information, namely to cassettes with flexible magnetic disks and to the driving mechanisms for them.
    A cassette with a flexible magnetic disk, comprising rigidly connected rectangular crash s, between which a flexible magnetic disk is located, and a driving mechanism for a cassette with a flexible magnetic disk containing a chassis, which strengthened an electric motor mounted with the possibility of acting on a flexible magnetic disk, are known. Known cassette and a driving mechanism provide rotation of a flexible magnetic disk with the relative simplicity of their design lj.
    A disadvantage of the known cassette and driving mechanism is the considerable complexity of their maintenance.
    A cassette with a flexible magnetic disk is also known, which includes an upper and lower rectangular trough-shaped springs, which are connected together, between which is a flexible magnetic hub, coaxially mounted on a core placed rotatably in the central drive hole of the lower rectangular trough-shaped lid, and a connecting element, and driving mechanism for a floppy disk cartridge.
    comprising a chassis on which a motor is fixed, having a rotor, the shaft of which is mounted to be accommodated in a flexible core
    a magnetic disk located in the central driving hole of the lower rectangular trough-shaped grip. These cassettes and the driving mechanism allow for relative ease of maintenance 2,
    The lack of such cassettes and the driving mechanism is a significant error in the installation of a flexible magnetic disk. This is explained by
    significant error installation core of a flexible magnetic disk on the rotor shaft of an electric motor.
    The purpose of the invention is to reduce the installation error of a flexible magnetic disk.
    The goal is achieved in a cassette with a flexible magnetic disk containing connected upper and lower rectangular trough lids, between which there is a flexible magnetic disk coaxially mounted on a core placed rotatably in the central driving hole of the lower rectangular trough-shaped grinder, and connecting the element, the core is made in the form of a cup of ferromagnetic material, has a square mounting hole 31 and a rectangular mounting drive hole and is provided with a lug-shaped protrusion connected to the flexible magnetic disk through the connecting element, the upper rectangular trough-shaped key made with an annular protrusion coaxially placed inside the core in which the square mounting hole and the rectangular mounting-driving hole are shifted in one direction relative to the axis of its rotation. In addition, the driving mechanism for a cassette with a flexible magnetic disk, comprising a chassis on which an electric motor is fixed, having a rotor whose shaft is mounted with the possibility of accommodating a flexible magnetic disk in the core located in the central drive hole of the lower rectangular trough-shaped cassette tape against it an upper rectangular, pyrex shaped claw, a rotatable flat claw is inserted, provided with spring-loaded clamping pins and fixed on a chassis, completed with fixed supporting pins A horseshoe-shaped plate spring mounted on the rotor of an electric motor and fitted with a driving pin rigidly connected to it mounted with the possibility of acting on the core of a flexible magnetic disk and a disk-shaped rim mounted on the rotor shaft of the electric motor and fitted with permanent magnets mounted with the possibility of mounting a magnet mounted on it. a flexible magnetic disk, with the spring-loaded clamping pins mounted with the possibility of simultaneously pressing the upper rectangular trough-shaped roof The cassette pulleys to the rotor shaft of the electric motor, and its lower rectangular trough-shaped cassette to the fixed supporting pins of the motor. The proposed cassette and driving mechanism due to the fact that the core is made in the form of a cup of ferromagnetic material and has a square mounting hole and a rectangular mounting and driving hole, as well as by introducing a rotary flat head, a horseshoe-shaped plastic spring and a disc-shaped frame, allow significantly reduce the installation error of the flexible magnetic disk. FIG. I shows a cassette with a flexible magnetic disk; FIG. 2 shows the arrangement of a flexible magnetic disk; Fig. 3 shows the arrangement of the square mounting hole and the rectangular mounting and driving hole on the core; in fig. 4 driving mechanism for a floppy disk cartridge; FIG. 5 shows the arrangement of the core of a flexible magnetic disk on the rotor shaft of an electric motor. The proposed cassette contains rigidly connected upper and lower rectangular trough-shaped supports 1 and 2, between which a flexible magnetic disk 3 is located. Flexible magnetic 1 disk 3 is coaxially mounted on the core 4, placed rotatably in the central drive hole 5 of the lower rectangular core-shaped ribs 2, The core 4 is made in the form of a cup made of ferromagnetic material, has a square mounting hole 6 and a rectangular mounting and driving hole; 7 and is equipped with a flange-shaped protrusion 8, with united with the flexible disk 3, through the connecting element 9, for example, through an adhesive washer. In this case, the upper rectangular trough-shaped lid 1 is provided with an annular protrusion 10 coaxially placed inside the core 3, in which the square mounting hole 6 and the rectangular outer drive hole 7 are offset in one direction relative to the axis of its rotation. The proposed driving mechanism comprises a chassis 11 on which an electric motor 12 having a rotor 13 is fixed, the shaft 14 of the rotor 13 is mounted to be placed in the square mounting hole 6 of the core 4 of a flexible magnetic disk 3 located in the central driving hole 5 of the lower rectangular trough-shaped cassette cover 2 against its upper rectangular trough-shaped lid 1,. The proposed driving mechanism also contains a pivoting flat cover 15, fitted with spring-loaded clamping pins 16 and mounted on chassis II, made with non-movable pins 17, a horseshoe-shaped lamellar spring 18 and, with an eye-shaped spacing 19. The horseshoe-shaped plate spring 18 is fixed on the rotor 13 electric motor. the wife is rigidly connected with her Hbw drive with a finger 20, installed with a cart. the possibility of acting on the core 4 of the flexible magnetic disk 3 through its rectangular mounting-drive hole 7. The disk-shaped is fixed on the shaft 14 of the rotor 13 of the electric motor 12 and is equipped with permanent magnets 21 installed with the possibility of attracting the core 4 of the flexible magnetic disk 3. Therewith spring-loaded The rectangular pins I6 are mounted with the possibility of simultaneously pressing the upper rectangular trough-shaped lid 1 of the cassette to the shaft 14 of the rotor 13 of the electric motor 12, and its lower rectangular roof-shaped ki 2 - to the fixed chassis supporting pins 17 1I, A proposed cartridge is also provided with openings 22, the recording-reproducing and a mounting cutout 23, and comprises a latch 24. Latch 21 is mounted on the cassette with the possibility zakrshani otkrgeani and its openings 22 recording-reproducing. The proposed driving mechanism also includes an additional electric motor 25 mounted on the chassis 11 and kinematically connected to the carriage 26 on which the magnetic head 27 is mounted, mounted to be able to radially move relative to the flexible magnetic disk 3 in the cassette playback recording hole 22. The chassis II is provided with posts 28, in which the axles 29 of the swiveling flat cover 15 are installed, and an installation protrusion 30 mounted to be placed in the installation notch 23 of the cassette. Before recording or playback, the proposed cassette is inserted into the proposed driving mechanism. When the cassette is inserted, the mounting protrusion 30 enters the installation notch 23, the magnetic head 27 enters the recording-reproduction hole 22, the rotor shaft 14 of the electric motor 12 into the square mounting hole 6 of the core 4, and the driving pin 20 into the rectangular mounting drive hole 7 of the core 4 Moreover, the shaft 14 of the rotor 13 of the electric motor 12 abuts against the upper rectangular trough-shaped pin 1 of the cassette, and the permanent magnets 21 attract the core 4. During recording and playback, the rotation of the shaft 14 of the rotor 13 of the electric motor 1 2 is transmitted through the drive pin 20 to the flexible magnetic disk 3. In addition, the additional motor 25 radially moves the magnetic head 27 relative to the rotating flexible magnetic disk 3. The use of the invention compared to the basic object significantly reduces the installation error of the flexible magnetic disk.
