ABSTRACT:
A word line number count/display device used in a tape recorder for dictation includes a magnetic head for detecting a special cue signal from a magnetic recording tape while the tape is running in either of two opposite directions, and for generating a detection signal corresponding to the length of a main communication content of dictation recorded on the tape. A time measuring circuit electrically connected to the magnetic head measures the time length corresponding to the length of the main communication content and generates a time period signal corresponding to the measured time length. A dividing circuit electrically connected to the time measuring circuit divides the time period signal by a predetermined reference time period value to produce a quotient signal, and a multiplying circuit multiplies the quotient signal by a predetermined value corresponding to the average number of words spoken by a dictator during a predetermined period of time divided by the average number of words contained in one line of a typing paper. A resulting product signal is provided to a decoder which produces a digital signal corresponding to the product signal from the multiplying circuit. A digital display device displays digital information corresponding to the digital signal.
