VCR Deck Operating Description
8-3-2 Reel Drive System
The reel drive system consists of a capstan motor as a drive power source, belt as a power transmission mecha-
nism, clutch mechanism, idle gears, and a reel disc. Selecting of forward rotation or reverse rotation is carried out
by an idle gear which changes its rotating direction according to rotating direction of the clutch holder.
Reel take-up torque is selected according to an operation mode.
In the record, playback, fps, rps modes, the reel take-up torque is controlled by the clutch mechanism, thereby the
tape fed by the capstan is taken up with a proper torque.
In the FF and REW modes, the clutch enters a direct connecting status in which the clutch mechanism does not
operate and the capstan drive torque is transmitted without reduction, so a high speed taking-up is enabled.
