Abstract
A tape transport system for cassette tape recorders wherein a member engages the drive belt between the two flywheels and exerts a dragging action, such that the belt lengths each side of the member will be respectively tight or not tight according to the direction of rotation of the drive pulley thus increasing the traction on the tight length of the belt. The corresponding pulley will rotate at a slightly higher speed than the other pulley and the tape length between the two transport units will always be automatically tightened up.
Claims9
Improved tape transport system for a magnetic tape recorder comprising:
- a bottom plate integrally formed with said magnetic tape recorder;
- a first tape transport unit adapted to continuously exert a gripping action on said tape, said first transport unit comprising a first flywheel supported on said plate and having a peripheral race;
- a second tape transport unit also adapted to continuously exert a gripping action on said tape, said second transport unit comprising a second flywheel also supported on said plate and having a peripheral race;
- a drive pulley adapted to be driven by a motor member;
- a drive belt received within the race of said drive pulley and the race of said flywheels so as to transmit the rotation of said drive pulley thereto, in the same direction, and,
- a member adapted to exert a dragging action on the length of said drive belt comprised between said flywheels for tightening up the belt length moving from said member towards said drive pulley.
A drive system for the tape transport elements of a magnetic tape recorder comprising:
- a bottom plate integrally formed with said tape recorder,
- first and second capstan axles journaled in said bottom plate,
- first and second flywheels fixed on said first and second axles, respectively,
- and adapted to constitute first and second pulleys, each having peripheral races,
- a reversible drive pulley having a peripheral race mounted on said plate,
- a drive belt frictionally engaged within the races of all pulleys, and
- drive belt drag means mounted on said plate in a position to contact the drive belt along its run between the first and second pulleys and to exert a dragging force on the movement of said belt in either direction.
