ABSTRACT:
A reel table driving apparatus for a tape cassette recorder includes a main plate, a reel table having a reel disk rotatably installed on the main plate, a driving gear coaxially combined with the reel disk, for transmitting a driving force, and a friction gear having a larger diameter than that of the driving gear, for transmitting the driving force to the reel disk by a frictional engagement with the driving gear. The apparatus further includes a first intermediate gear selectively engaged with the friction gear, a second intermediate gear which is engaged with the driving gear, elevating means for elevating the first intermediate gear to be engaged with the friction gear in a low-speed, mode and separated from the friction gear in a high-speed mode, and an idler mechanism having a first idler gear corresponding to the first intermediate gear and a second idler gear corresponding to the second intermediate gear, coaxially installed with the first idler gear and having a larger diameter than that of the first idler gear, such that the first idler gear is engaged with the first intermediate gear in the low-speed mode and the second idler gear is engaged with the second intermediate gear in the high-speed mode.
