<p>PURPOSE:To make a tape recorder small-sized and elevate its workability by constituting it so that the tape travelling system is driven by the driving force in case of forward turn of the motor, and the travelling direction of the tape is switched by the driving force in case of reverse turn of the motor. CONSTITUTION:A pulley 34 is installed through the one-way clutch 36 to a pulley 32 which rotates in one body with the motor shaft 30 of the motor which can be turned in both the forward and reverse directions, a capstan belt 40 is held fast between the pulley 34 and fly-wheels 24, 26, and the fly-wheels 24, 26 are rotated in the directions as indicated with arrows 42, 44. Also, a belt 180 is held fast between the pulley 32 and the pulley 156, the turning force of the motor 28 is speed-reduced in proportion to the diameter ratio of both the pulleys, and it is transmitted to the pulley 156. The one-way clutch 162 is constituted and placed between the pullet 156 and the gear 158 so that the turning force of the motor 28 in the direction as indicated with an arrow 164 is transmitted to the gear 158.</p> |
