ABSTRACT:
A device for driving an idler of a deck mechanism of a video cassette recorder. This device comprises a tape supply reel and a tape take-up reel, both reels being rotatably mounted on a base plate of the deck mechanism and rotated by a rotational force of a capstan motor, a function plate linearly reciprocating by a rotational force of a loading motor, a gear pulley applied with the rotational force of the capstan shaft through a belt, a transmission gear assembly driving the idler by the rotational force of the gear pulley to rotate either of the tape supply reel or the tape take-up reel, and a turning member rotating, in cooperation with the function member, the second transmission gears to cause the idler to gear into either of the tape supply reel and the tape take-up reel prior to transmission of the rotational force of the capstan shaft to the reel gearing into the idler. The gear assembly comprises a clutch assembly including upper and lower clutch gears and an operating gear fixedly coupled to the transmission clutch gear. The turning member is provided with a gear section, gearing into the operating gear, and with a guide slit slidably receiving a connection pin of the function member.
