<p>PURPOSE:To exactly detect the rotation and the stop of a rotational body without increasing the power consumption by allowing the moving body of a detection lever to stop at a position where it is moved by the cam face, when a reel base stops and the detection lever becomes a non-oscillating state, and abutting a detection claw against the moving body. CONSTITUTION:On the tip part projected to the outside of a chassis substrate 5 of a cassette locking lever 89, a cassette holder open button 91 is provided, and when it is pressed, the lever 89 is pressed in the direction as indicated with an arrow Y against energizing force of an energizing spring 90, a locking piece 89a also moves in the same direction and an engagement from a piece to be locked of a cassette holder 79 is released, the holder 79 becomes freely rotatable and turns to the outside from the cassette installing position side, and a cassette 4 becomes to be inserted and detached freely. Also, when a reproducing lever 24, a fast forward lever 26 and a rewinding lever 26 are selected, a switch plate 29 moves in the direction as indicated with an arrow D', and end part 29c of the slide plate 29 approaches a projecting part 89b provided projectingly on the end part of the lever 89, and even if the button 91 is depressed, the movement of the lever 89 is inhibited, and the holder 79 becomes a fixed state by a cam gear 30.</p> |
