摘要

A tape deck which incorporates a take-up reel rotation sensing switch and associated sensing circuit for enabling the capstan and take-up reel drive mechanism includes a sensing switch which only rotates with the take-up reel when it is driven in the take-up direction. If the take-up reel changes direction, due to tape windup on the capstan, the switch does not rotate and the sensing circuit disables the drive mechanism to prevent excessive tape windup on the capstan.
