Abstract
An apparatus for detecting the stop of a magnetic tape traveling in a magnetic recording and reproducing device which carries out a plurality of functional modes and in which the magnetic tape travels at a speed corresponding to a selected functional mode, wherein a pulse generator produces one pulse per rotation of a magnetic tape-driving section. A time interval between the respective pulses issued from said pulse generator is determined from a number of reference pulses having a reference frequency which are delivered from a reference pulse generator and are later counted by a counter. A longer traveling time of a magnetic tape than that specified for the different functional modes is preset in a numeral code generator in the form of a numeral code. When the traveling time of a magnetic tape is found to be longer than that present for a selected functional mode, a detection signal based on an output count from the counter is issued to judge whether the magnetic tape has ceased to run.
