Abstract
PURPOSE: To enable to detect the binding of reel or the like due to external disturbance quickly, by providing a pulse count means which is reset with the logical sum between the pulse relating to tape running and on/off controlling signal of a reel pulse motor.
CONSTITUTION: The 1st pulse generating means 14 generating pulses relating to the running of a tape 2, and an OR circuit 17 which takes logical sum between the output pulse P3 and on/off controlling signal P5 of a reel motor 3, are provided. Further, the 2nd pulse generating means 18 generating the pulse in given frequencies and a counter 19 counting the output pulse P8 are provided, the counter 19 is reset with the output P7 of the said OR circuit 17, and the rotation of the reel motor 3 is controlled with the output P9 of the counter 19. Thus, mechanical binding of reels and motor due to external disturbance like wound tape 2 on the capstan 7 and due to internal disturbance like a failure in a reel motor driving circuit 16, can quickly and surely be detected.
