ABSTRACT:
A video tape recorder includes a capstan, a stationary magnetic head, a pair of rubber pinch rollers disposed on opposite sides of the capstan, and a pair of head-facing guides whereby to travel an endless tape at a high speed. Each pinch roller and head facing guide are mounted on a supporting member which may be rocked by a wire with a coil spring against the force of a tension spring so that the pinch roller and head facing guide can press the tape against the capstan and magnetic head. Such a state may be maintained by abutting the support member on a stop.
