SU1282209A1 - Cassette for magnetic tape recorder - Google Patents

Abstract

The invention relates to magnetic recording and permits an increase in operational parameters by stabilizing the density of the winding of a magnetic tape. Between rolls 2 and 3 placed clamp 5, made in the form of an ellipsoidal spring. The open ends are interconnected through the piezoelectric element 6. The clamp, installed with the possibility of compression of its lateral sides by rolls 2 and 3, ensures uniform tension of the tape over the entire diameter. The mechanical vibrations of the clamp, excited by the piezoelectric element 6, provide nudging of the turns of the tape of both rolls over the surface with reduced friction of the previous turn and the density of the tape winding. The cut at the end of the clamp increases the efficiency of vibration. When the cassette is mounted on the chassis of the tape recorder, the drive shaft 10 and the magnet head 9 are inserted into its chassis. 2 Il. i (L

The invention relates to magnetic recording and can be used in tape recording apparatus of magnetic recording and reproducing signals and sound.

The purpose of the invention is to increase the operational parameters by stabilizing the density of the winding of a magnetic tape.

Fig, 1 shows a cassette mounted in a tape recorder; FIG. 2 is a section A-A in FIG. 1, (mounting of a piezoelectric transducer),

The tape cassette includes a body 15, rolls 2 and 3 of a magnetic tape AZ clamp 5 in the form of an ellipsoidal spring with open ends connected by a piezoelectric element 65 to one end of the clamp 5 pivotally attached to the axis 7. , Besides; There is a magnetic head 9 and a driving shaft 10 in the recorder,

The device works as follows.

; 11it tension (5c) before entering the clamping sector 5 on the other hand, the process is facilitated by excitation; the shadow of mechanical oscillations on |; mode 5 with the help of a piezoelectric element 6 receiving voltage from the generator 8 the rolls of the cassette with the help of vibrations are pushed on the surface; - -: spines with reduced friction of the previous coil and the whole tape 4 is tightly mounted over the entire diameter. Pulse-to-tension is smoothed, the tape twists more evenly, and this ensures an increase in the operational parameters of the cassette. The Effectiveness of the vibrations of the vibrations. that the xp RC clamp 5 is cut, since Toivia has the flexibility of its arcs, which rolls 2 and 3 have a radius of a certain radius, and their constant pressure is ensured by the pressure on the axis 7.

When the cassette is installed on the chassis of the tape recorder, the drive shaft 10 and the magnetic head 9 are inserted inside it. The magnetic tape 4 is pressed against the drive shaft 2. To ensure the winding density over the entire diameter of the roll 3, the spring is elliptical with CM 5 installed compressing its sides of roll 2 and 3 of the magnetic tape with an airfoil, ensures that ESHTKII does not evenly stretch certain parts, but all over the diameter, since the departure from the pressing section 5 does not have time to release the sections of the coil (yMf: : -ii,
