Abstract

PURPOSE: To display tape running quantity with high accuracy by counting by each (n) or specified value based on this at each inputting of the period pulse in a relation of n:1 with the rotating periods of reel shafts, etc.
CONSTITUTION: With the rotating ratio of reel shafts 51, 52 and a pulley 9 running a cassette tape 1 being set at n:1, a frequency divider of 1/n is constituted by a mechanical means and a pulse generator 8 is constituted by a disc form electrode 10 of integral construction with the pulley 9 and a detector 11 making elastic contact with the circumferential edge thereof. The detector 11 outputs output "1" and "0" respectively to a one-short circuit 13 in the state of being held contacted the insulation part 10a of the electrode 10 and the conductive parts other than this to let a trigger pulse be generated. This pulse causes a running quantity count controller 15a to apply a count command signal to an AND 17 to which the code signal "n" is inputted from a code generator 18, causing a counter circuit 16 to make counting by each "N" at each (n) rotation of the drive parts. Thereby, the tape running quantity may be displayed with high accuracy.
