Abstract
PURPOSE: To quicken retrieval operation, by recording a pulse signal of lead-in station number through the provision of a space where recorded picture is erased at the desired lead-in location of a recorded tape, and the recognition of location from the shortest lead-in signal even on the way of taping.
CONSTITUTION: When a lead-in signal on recorded tape is selected 9, the tape turns forward 10, the shortest lead-in signal is detected and the present station number is recognized 11. If the difference between the present station number and the desired lead-in station number is positive, the tape is reversed 14, and if negative, the tape runs forward 15. The control circuit 13 gives instruction. Further, when the desired lead-in station number is obtained, the drive mechanism is stopped 17. If not detected, the tape end is detected, and if it is the tape end detection of the second time, the drive mechanism 19 is stopped 19. If NO, the reversing is made to continue the retrieval of station number.
