ABSTRACT:
A fast running mode conversion device for magnetic recording and reproducing apparatus. This device has a shaft supporter provided on the bottom surface of a base plate. An idler lifting lever for lifting or lowering an idler arm is pivotally mounted on the shaft supporter. A drive arm for driving the idler lifting lever is rotatably mounted on a shaft of the base plate. A biasing member coupled to the drive arm has a biasing lever for driving the idler lifting lever. The biasing lever extends toward the idler lifting lever. A function plate rectilinearly reciprocates by the rotating force of a cam gear, thus to turn the drive arm. The drive arm has an operating pin and the function plate has a pair of cam projections for cooperating with the operating pin when turning the drive arm.
