<p>PURPOSE:To save labor and to correctly set a picture recording starting position by providing a means to compare with a tape feeding quantity detected by calculating a necessary tape feeding quantity from a tape feeding time while the tape feeding time is designated together with the fast forwarding or rewinding and stop the fast forwarding or the rewinding when both are coincident. CONSTITUTION:The title device is provided with a means 5 to detect a tape feeding quantity at the fast forwarding and the rewinding and a means 6 to compare with a tape feeding quantity detected by calculating a desired tape feeding quantity from the tape feeding time while the tape feeding time is designated together with the fast forwarding or rewinding and stop the fast forwarding or the rewinding when both are coincident. Namely, the necessary tape feeding quantity is calculated from the travelling speed of the magnetic tape and together with this, the fast forwarding or the rewinding is executed. By detecting the magnetic tape at this time, the tape feeding quantity is detected, and the necessary tape feeding quantity calculated with this is compared. When both are coincident with each other, the fast forwarding or the rewinding is stopped. Thus, the labor is saved and the desired quantity of the magnetic tape can be fed.</p> |
