Abstract
A reel-table driving mechanism of a tape recording/reproducing apparatus is operative to selectively drive two reel-tables. An idler has an idler friction wheel sharing a common shaft with an idler gearing portion. Each reel-table has a reel friction wheel rotating while making contact with the idler friction wheel which ensures the idler gearing portion meshes with the reel gear while maintaining an appropriate distance between the shafts of the reel table and the idler.
Claims8
A reel-table driving mechanism for use in a tape recording/reproducing apparatus, comprising:
- two reel-tables each having a reel gear formed thereon;
- an idler movably installed between said reel-tables and having a gearing portion formed thereon for selectively engaging with the reel gears of said reel-tables,
- wherein said idler has an idler friction wheel sharing a common shaft with said idler on which said gearing portion is formed and wherein each of said reel-tables has a reel friction wheel which makes contact with an outer peripheral surface of said idler friction wheel while the gearing portion meshes with the reel gear and maintains an appropriate distance between a shaft of each of the reel tables and the shaft of the idler.
A reel-table driving mechanism comprising:
- two reel-tables each having a reel gear formed thereon;
- an idler movably installed between said reel-tables and having a gearing portion formed thereon for selectively engaging with the reel gears of said reel-tables;
- a capstan motor;
- and
- a driving gear driven by said capstan motor to rotate said idler,
- wherein said idler has an idler friction wheel sharing a common shaft with said idler on which said gearing portion is formed and wherein each of said reel-tables has a reel friction wheel which makes contact with an outer peripheral surface of said idler friction wheel while the gearing portion meshes with the reel gear and maintains an appropriate distance between a shaft of each of the reel tables and the shaft of the idler.
