Rotary dial for use in a video cassette recorder

摘要

A video cassette recorder operable in a plurality of picture search modes comprises a rotatable knob and a locking mechanism. The knob returns to an initial position thereof when an operational force applied thereto is released. Each of the picture search modes are selected in response to a respective angular displacement of the knob from the initial position. The locking mechanism has a locking arm urged to lock the knob while the video cassette recorder operates in one of the picture search modes.
