Abstract
A tape counter for a multispeed tape recorder having a multispeed tape transport, a speed switch for designating a specific tape speed of the transport, a tape running detector for generating count pulses in accordance with a reel rotation of the transport, and a counter for counting the count pulses. The tape running detector includes a variable frequency converter such as a variable frequency divider. The frequency divider performs, for example, a 1/2 frequency division when the speed switch designates a tape speed of 2.4 cm/s and performs a 1/1 frequency division when the speed switch designates a tape speed of 1.2 cm/s.
