<p>PURPOSE:To separate a belt transmission mechanism, to execute the transmission without fail and to secure a stable action control by driving and controlling independently first and second tape recorder driving mechanism parts with first and second cam gears respectively. CONSTITUTION:First and second tape cassettes mounted in a laminated shape are respectively driven by a laminated type driving mechanism 20. At shafts 24 and 25, reel shafts 22a and 22b, and 23a and 23b are supported freely turnably and gears 26-28-30 and 27-29-31 are given to a base. By a main motor 54, capstans 52 and 53 are driven, a slider is moved in a tape travelling direction by a plunger, and then, a cam gear is turned, the slider is moved and a pinch roller at the right side is pressed against the capstan 53. A gear 34 of a reel motor 32 is moved through an oscillating member 35 in a direction B, selectively geared to the gear of the right reel shaft, only a right reel is turned at the selected speed, and a magnetic head is also switched. By such a constitution, the driving mechanism 20 is driven and controlled with a cam gear respectively stably.</p> |
