ABSTRACT:
Disclosed is a braking mechanism for use in a magnetic recording apparatus essentially comprising a single cam gear and a brake-releasing member. The cam gear and the brake releasing member are so operatively connected that a stepwise rotation of the cam puts selected brake releasers in different brake releasing positions. Specifically in the first releasing position only the supply reel of the apparatus can rotate freely; in the second releasing position the take-up reel of the apparatus can rotate freely, and the supply reel can rotate against a relatively weak resistance; in the third releasing position the take-up and supply reel brakes can rotate freely together; and in unreleased position the supply and take-up reels cannot rotate.
The sequential releasing of selected brakes assures coordination of braking operations appropriate for tape-loading, unloading, quick winding, playing and stopping. Such a simple combination of a cam gear and a brake-releasing member according to present invention permits reduction of the number of required parts and the size of the brake control.
