<p>PURPOSE:To start dubbing stably and surely with simple operation by detecting the loading end of both VTRs in response to a dubbing button, giving a reproducing command to one VTR and then giving a command of video recording of the other VTR. CONSTITUTION:When the dubbing button 1 is depressed for dubbing from the VTR V1 to the V2, loading is commanded to the VTRV1, V2 via a control circuit S. When the loading is finished, an output of an AND means 13 detecting it is inverted into a high level, the VTRV1 is in the reproducing state via a reproduction command means 15, and the VTRV2 is rewound by a prescribed amount of a tape in response to a short wind command means 14 and brought into in the stand-by state. After the VTRV1 generates a stable reproduced output via a consecutive recording command means 17 and an EE switch changeover means 19 in response respectively to delay circuits 16, 18, the VTRV2 is brought into the video recording state, and the reproduced output of the VTRV1 is fed to the V2. The dubbing from the VTRV2 to the V1 is the same and sure dubbing is started automatically with simple operation by only depressing the dubbing button similarly.</p> |
