Abstract

The solution can be used in normal appliances for magnetic tape recordings and improves the quality of motion at the cost of toothed gear coupling precision. For this purpose there are guiding grooves (9 to 11) on the setting panel (1), one of which - the oblongitudinal one (9) - is positioned between the two triangular ones (10 and 11) with oppositely oriented apices. The rewind knot consists of a pair of coupled toothed gears (7 and 8) with axes (13 and 14) and a slider (12) with side rotation groove (21) and with a projection of gradual motion (22), on which there are axes (13 and 14) and a pin (17); The free projections (15 and 16) of the axes (13 and 14) and the pin (17) are arranged in appropriate way in triangular and quadrangular guiding grooves. The control rewind knot contains two shifting buttons one of which is coupled with the groove of rotation on the slider (12) and the second one - with the projection of gradual motion on the slider (12) through the intermediate lever (23) suspended to the proximal axis of the rewind knot toothed gear.<IMAGE>

Description

(57) Interference can be used in conventional tape recorders and makes it possible to improve the quality of movement at the expense of the gear coupling accuracy. For this purpose, guide grooves (9 to 11) are provided on the adjusting panel (1). of which one - rectangular (9). it is distributed between two triangular (10 and 11), with the aptly oriented vertices. The rewinding node comprises a pair of coupled gears (7 and 8) with axes (13 and 14). and also a slider (12) with a side pivot groove (21) and a step displacement protrusion (22). on which the axes (13 and 14) and the pin (17) are fixed, the free projections (15 and 16) of the axes (13 and 14) and the pin (17) are respectively distributed in triangular and rectangular guide grooves. The rewinding control node comprises two push buttons, one of which is coupled to a pivot groove on the slider (12). and second, with a projection of successive displacement on the slider (12) over the intermediate lever (23). supported to the nearest gear axis of the rewinding node.
