ABSTRACT:
A tape recorder is adapted to process at a different priority order by the same logic a magnetic tape run count function and time count processing function and includes a first logic register for counting a detection pulse which is outputted from a magnetic tape run detection section with a cycle enough longer than a maximum processing time required for the time count processing, the detection pulse being outputted during no time count processing time. A predetermined dummy count value is stored in a memory so as to count an interval between detection pulses which are outputted with an enough longer cycle. The dummy count value is supplied by a calculating circuit to said first register.
