ABSTRACT:
A mechanism to move reels and a tape cassette sensing switch, for use in a magnetic recorder which includes: a power generating unit installed on a position of a main chassis; a moving member combined with a bottom surface of the main chassis in such a manner that the moving member can be rectilinearly moved back and forth; a power transmitting unit for transmitting power from the power generating unit to the moving member; a supply reel driver and a take up reel driver respectively installed on the bottom surface of the main chassis in spaced apart relation from each other; reel driving gears respectively combined with and fixed to rotary shafts of the supply and the take up reel drivers; and a reel supporting unit concentrically combined with the reel driving gears on the main chassis and including thereon a supply reel and a take up reel. The reel supporting unit is rotated by a predetermined angle according to the rectilinear movements of the moving member.
