Abstract
A capstan drive tape recorder having a pressure roller on an arm which is pivotable to hold the tape against the capstan. To move the arm between the operating and a rest position, the arm is connected by a spring to a lever, the arm and lever being pivotable about the same axis. An actuating device moves the lever to bring the pressure roller into engagement with a tape against the capstan. In moving the arm, the lever is first pivoted about one axis, and then about a second axis so that the mechanical advantage of the lever is changed between a ratio which moves the roller a considerable distance, and a ratio which biases the roller against the capstan.
