PURPOSE: To obtain an adapter device of a VTR which can continuously reproduce a plurality of video tapes and can be simply assembled into a system.

CONSTITUTION: When a start switch 19 is turned ON in a continuous playback mode, switches 103, 106 are connected to an (a) side, and a code signal (playback) from a generator 101 is fed to a VTR 1A by a light emitting part 21a, so that the playback state is obtained. A reproduced video signal is guided out to a terminal 15OUT. When a detector 107 detects the completion of the playback state of the VTR 1A, a code signal (rewind) from the generator 101 is supplied to the VTR 1A by the light emitting part 21a, whereby the VTR 1A is turned into the rewinding state. Thereafter, switches 103, 106 are connected to a (b) side, and a code signal (playback) from the generator 101 is sent to a VTR 1B by a light emitting part 21b to bring the VTR 1B into the playback state. A reproduced video signal is sent out through the terminal 15OUT. Subsequently, the VTRs 1A and 1B are alternately turned to the playback state in the same manner as above.
