    PURPOSE:To realize high-reliability contact between a sheet and a head, by making an interval adjustment of the position of a regulating plate on the basis of the position of a guide plate for the sheet by a small-sized magnetic sheet device. CONSTITUTION:A case cover 26 is fitted to a case base plate 25 so that the cover can be opened and closed, and the base plate 25 has a sheet rotating table 27, a magnetic head 28, a head moving part 29, a motor 30, etc. For recording, a sheet device is equipped, the cover 26 is closed, and the contact of a sheet with the head 28 is stabilized by a lower guide plate 31 as a guide plate and an upper guide plate 32 as a regulating plate, thereby achieving high-reliability recording and reproduction. In this case, positioning pins 31J and 31K on a plate 31 engage with the plate 32, and an upper fitting plate 40 engages with the upper end 27F of a rotating shaft 27A to make a three-point engagement contact, so that an interval adjustment of the position of the plate is made on the basis of the position of the plate 31.

    The invention relates to the accumulation of information, namely to cassette devices for recording and reproducing on a flexible magnetic disk. A cassette device for recording and reproducing on a flexible magnetic disk, containing a magnetic head mounted on a holder, and a driving shaft mounted with possibility of interfacing with floppy disk installed in the cash register. The device allows recording and playback on a magnetic disk with the relative simplicity of its design l. The disadvantage of a cassette device is the considerable complexity of its maintenance. It is also known a cassette device for recording and reproducing on a magnetic disk, containing a magnetic head mounted on a holder, a drive shaft mounted to mate with a sleeve of a flexible magnetic disk mounted in a cassette made with inlets, and placed between the cover and the base of the casing, and the adjusting screws. This cassette device allows for relative ease of servicing it. 2 The disadvantage of the known cassette device is its large size and considerable uneven contact between the magnetic head and the flexible magnetic disk. This is due to the complexity of simultaneously reducing the size and ensuring sufficient contact uniformity between the magnetic head and the flexible magnetic disk. The purpose of the invention is to reduce the dimensions of the cassette device and reduce the uneven contact between the magnetic head and the flexible magnetic disk. The goal is achieved in that in a cassette recorder for recording and reproducing on a flexible magnetic disk containing a magnetic head mounted on a holder, a drive shaft mounted to mate with a sleeve of a flexible magnetic disk mounted in a cartridge made with inlets, and placed between the cover and the base of the casing, and the adjusting screws, the first guide plate is inserted, made with a hole in which the magnetic head is located, with supporting pins and with the first platform, the size a cassette of a flexible magnetic disk with a first inlet; a second guide plate, spring-loaded to the housing crown; a disk, and with a rotation phase detection coil, and an annular permanent magnet coaxially mounted in the drive shaft, and the magnetic head holder is designed as a spring-loaded swivel lever, the flexible magnetic / disk bushing is provided with a coaxially arranged annular magnetic element and a magnetic pin mounted to act on the rotational phase detection coil, the adjusting screws are fitted with a pair of ends of the supporting pins, and the first and second platforms are located opposite each other from opposite sides of a flexible magnetic disk. FIG. 1 shows one of the possible variants of the proposed cassette recorder for recording and reproducing on a floppy disk; in fig. 2-4 different types of floppy disk cassettes. The proposed cassette device contains a drive shaft 1, kinematically connected by means of a belt 2 to an electric motor 3 and placed between the cover 4 and the base 5 of the casing, and the magnetic head 6. In this case, the magnetic head 6 is fixed on the holder 7, made in the form of a spring-loaded rotary lever, and the leading the shaft 1 is mounted to mate with a sleeve 8 of a flexible magnetic disk 9 mounted in a cassette 10 made with the first and second inlets 11 and 12. The proposed cassette device also contains a first guide plate 13, a second guide plate 14 and an annular permanent magnet 15 coaxially mounted in the drive shaft 1. The first guide plate 13 is provided with a hole 16 in which the magnetic head 6 is located, with supporting pins 17 and the first platform 18 placed in the first inlet 11 of the cartridge 10 of the flexible magnetic disk 9. The second guide plate 14 is spring-loaded to the cover 4 of the casing with the possibility of translational movement relative to it and made with openings in which screws 19, with a second platform 20 placed in the second inlet 12 of the cartridge 10 of the flexible magnetic disk 9, and with a rotational phase detection coil 21. In the proposed cassette device, the sleeve 8 of the flexible magnetic disk 9 is provided arranged coaxially
    an annular magnetic element 22 and a magnetic pin 23 mounted to act on the coil 21 for detecting the rotation phase. In addition, in the proposed cassette device adjustment screws
    19 installed with the ability to mate with the ends of the support pins 17, and the first and second platforms 18 and
    20 are located one against the other from opposite sides of the flexible magnetic disk 9.
    Recording and playback on a floppy disk using the proposed cassette device is as follows.
    After installing the cassette 10 between the cover 4 and the base 5 of the casing, the annular permanent magnet 15 attracts the annular magnetic element 22, providing the transmission of rotation of the drive shaft 1 to the flexible magnetic disk 9. The flexible magnetic disk 9 rotates between the first and second platforms 18 and 20, the distance between them is established by means of adjusting screws 19 interacting with the ends of the supporting pins 17. At the same time, the first and second platforms 18 and 20 provide for the formation of protective air bags between them and the rotation flexible magnetic disk 9.
    During recording and playback, the holder 7 moves the magnetic head 6 in the hole 16 of the first guide plate 13 radially relative to the rotating flexible magnetic disk 9. The interaction of the magnetic pin with the rotation phase detection coil 21 ensures the phase position of the flexible magnetic disk 9.
    The use of the invention as compared with the base object allows a considerable reduction in the dimensions of the cassette recording and reproducing apparatus on a flexible magnetic disk and reducing the uneven contact between the magnetic head and the flexible magnetic disk.
