Abstract
PURPOSE: To detect tape positions highly accurately by changing over a first means of obtaining the current position with the rotating period of one reel and a second means of obtaining the current position based on the ratio of the rotating periods of both reels and displaying the positions.
CONSTITUTION: Rotation detectors 7, 8 are provided respectively to the shafts of the supply reel 2 and wind-up reel 3 of a cassette 1 and the pulses from these are inputted to period measuring circuits 12, 13. Those from the circuit 12 are sent to a calculating circuit 14 and those from the circuit 13 are sent together with the output of the circuit 12 to a calculating circuit 15, whereby the data signals of the digital values indicating the current positions of the tape are obtained. These signals are then displayed in a display device 16 via changeover circuit 18. Hence, the use of the calculating circuit 14 at the recording and reproducing modes and the calculating circuit 14 at the fast feed and rewinding modes enables tape position displaying to be performed irrespective of running speed and enables highly accurate position detection to be performed.
