Claims

[Scope of utility model registration request]

a pair of sensors arranged at a constant angle to detect a reel stand rotated by a motor or a rotor of the motor; a waveform shaping circuit that shapes pulses from the sensor; and the waveform shaping circuit. A tape counter that performs arithmetic processing using an electronic counter through an AND gate that is selectively opened by pulses of different phases from the tape counter.
