<p>PURPOSE:To attain the reserved video recording standby state automatically at the optimum tape position by calculating a video recordable time of an interblock of a loaded magnetic tape, comparing the video recordable time and the reserved video recording time and bringing the reserved video recording standby state at the initial position of the interlocking part at the top whose video recordable time is longer than the reserved video recording time. CONSTITUTION:A timer switch SW 2 is connected to a timer microcomputer 21 and when the switch is turned on, the timer microcomputer 21 and a system control circuit 20 are brought into the reserved video recording standby state. The counter reset and the operation of a memory counter are executed by a counter reset command signal (g) and a memory counter command signal (h) from the system control circuit 20. The memory counter command signal (h) is fed to a base of a transistor (TR) 3 from the system control circuit 20 to conduct the TR 3 and also to conduct a TR 4 thereby operating the memory counter. Further, the memory counter stores the reset tape position and when the tape reaches the reset position during rewinding, tape running is stopped automatically by its function.</p> |
