ABSTRACT:
An idler gear transfer control apparatus for a reel drive apparatus of a VCR, is disclosed, wherein the VCR includes a reversible motor, a base, a shaft disposed at the base, an input gear rotatably disposed on the shaft for receiving a driving force from the motor, and an idler arm having one end rotatably connected to the shaft and another end carrying an idler gear connected to the input gear, the idler arm being movable about the shaft for engaging the input gear, the idler arm being movable about the shaft for engaging the idler gear selectively with a supply reel gear or a take-up reel gear, whereby the driving force of the motor is selectively transferred to the supply reel gear or the tape-up reel gear in accordance with a rotation direction of the input gear. The idler gear transfer control apparatus includes a plurality of stoppers provided at the one end of the idler arm connected to the shaft for limiting the movements of the idler arm, and a cassette lock release having a flat top surface for selectively engaging with the stoppers, wherein the idler gear is moved by the driving force of the motor and contacts the supply reel gear or the take-up reel gear, before or at the same time one of the stoppers contacts the flat top surface of the cassette lock release.
