Abstract
In a magnetic recording/reproducing apparatus, an idler gear is selectively moved between controlling a take up reel and a supply reel. An idler controlling apparatus limits the swing angle of the idler to a relatively small angle when the upper chassis is being seated on the lower chassis or when the tape is being ejected. The idler controlling apparatus also permits a wide swing angle of the idler when the tape recording/reproduction operations take place. The wide swing permits the idler gear to selectively control the take up and supply reels.
Claims5
In a magnetic recording/reproducing apparatus of the type having a drum, an upper chassis and a lower chassis;
- said upper chassis having thereon a supply reel and a take up reel for supplying and taking up a travelling tape;
- said lower chassis having thereon a driving source and an idler mechanism for providing the power of said driving source selectively to said supply and take up reels;
- said idler mechanism being positioned on said lower chassis to swing through a swing angle .theta..sub.1 where it meshes with said supply reel when at one extreme of said swing and meshes with said take up reel when at the other extreme of said swing;
- and a ring gear operative during loading and unloading of said tape onto and off of said drum;
- the improvement comprising:
- idler controlling apparatus responsive to said ring gear for selectively permitting said idler mechanism to swing through said angle .theta..sub.1 and limiting said idler mechanism to a swing through an angle .theta..sub.2, where .theta..sub.2 is wholly within .theta..sub.1 and wherein the extremes of the swing through angle .theta..sub.2 do not permit said idler mechanism to mesh with either said supply reel or said take up reel.
