ABSTRACT:
A manual cassette rewinding apparatus for allowing the user to rewind a cassette using an ergonomical pulling action on a string. The rewinding apparatus has a pulley rotatably mounted inside a housing. A string is winded around the pulley. A driving pin linked to the pulley is adapted to rotate jointly with the latter only when the string is being unwinded from the pulley. A spring is used to rewind the string around the pulley. The driving pin is adapted to be inserted into the hub of a cassette and the sting to be alternatively pulled and allowed to rewind by the user. When the string is pulled it rotates the driving pin thus rewinding the cassette.
