Abstract

PURPOSE: To improve the joint shooting accuracy and also to shorten the composite photographing time by setting a tape driving speed at 90% normal level, for example, in a composite photographing mode and then performing the video recording at a normal speed when the coincidence of phase is obtained with a control pulse which is recorded by the composite photographing.
CONSTITUTION: When the drive of a tape 1 is started at a speed of approximately 90% normal level at a time point t1, a control pulse CTL is supplied to a comparator 45 from a head 16 via a switch circuit 43 and an amplifier 44. Then the phase of said pulse CTL is compared with that of a control pulse CTL given from a pulse forming circuit 30. The comparison output COMP is supplied to a system control circuit 40 where the difference of phase is checked between both pulses CTL by the output COMP. Then the drive voltage MDRV of positive polarity is supplied to a motor 49 at a time point t2 when said difference of phase is reduced satisfactorily. Thus a pinch roller is pressed to a capstan. Hereafter the tape 1 is drive at a normal speed.
