A video tape recorder having a fast screen detecting device which includes a pinch lever which is driven by a master cam, and a control device comprising a brake lever for driving main brakes. The brake lever has a cam part in contact with the bent part of the pinch lever so that the brake lever is also driven by the master cam. Further, a guide post, driven by the master cam, partially loads video tape to enable control signal detection by a control head; the video tape in the partially loaded condition is not in contact with the head drum so that excessive tape wear is avoided.
