Claims

[Claims for Utility Model Registration] A synchronization separation means for separating a composite synchronization signal from a reproduced video signal, an integrating circuit for integrating the output of the synchronization separation means, and a discrimination circuit for determining the magnitude of the output of the integration circuit and a reference voltage. , means for placing the tape in a low-speed drive state lower than that during normal playback based on a still command; and an output from the discrimination circuit in the low-speed drive state. A still playback device comprising a stop means for stopping the tape at the time of occurrence.
