Abstract
A reel which rotates to wind or feed out the recording or recordable tape wound therearound is set in a cartridge. The reel rotation is locked by a reel lock that seizes the reel by being pushed against the reel with a spring and is unlocked by the release pad pushed back against the force of the spring. The release pad has a pivot, of which tip has a partial globe shape head, on the surface facing to the reel lock and the reel lock has a recess on the surface facing to the release pad. The curvature of the recess is larger than that of the pivot. The head of the pivot contacts within the recess. Then the pivot and the recess on reel lock surface can keep uniformly wear out in tape winding or feeding out and the reel lock hardly generates sound noise in the operation.
