Abstract

PURPOSE: To obtain the recording knob release device which permits rapid recording operation with simple construction by providing a lock wire so as to become lockable in the push position when the recording knob is pushed where the main switch knob is in the Sound position.
CONSTITUTION: If a main switch 5 is turned and is held set in the Sound position and when a recording knob 12 is pushed, the end part 53t of a lock wire 53 engages with the heart type cam groove on the inner side of the recording knob 12 by the action of a spring 75 which pushes the lock wire 53 inward, whereby the recording knob is locked. Hence, the recording knob is prevented from resetting upward and is held set in the record state. When the recording knob is pushed downward again, the lock wire 53 is reset upward by the action of a spring 35 and the recording knob 12 resets to the home position. This positions permits the rapid recording knob operation when the required image plane comes, thus the recording knob release of sure operation may be accomplished.
