<p>PURPOSE:To make the device thin and small in size, by driving the 1st reel stand with the tension of belt belted on a motor and a capstan wheel, changing an idler in resisting against the tension of belt, and driving the 2nd reel stand. CONSTITUTION:In converting the mode from the stop mode as shown in Figure to the recording/reproduction mode, a switch 70 turns on, a motor 2 rotates toward the arrow, and a capstan flywheel 8 and an idler 24 are driven toward the arrow with a belt 10. An idler plate 20 is pressed on the belt 10, gears 24b and 14a are geared to drive a winding reel stand 14. The fast feed pushes left a button 54 to turn on a witch 54b, the motor 2 is rotated in high speed to be the fast feed. In the rewinding mode, the button 54 is pushed right, to turn on a switch 72, the idler plate 20 is rotated counterclockwise in resisting against the tension of the belt 10, and the gear 24b drives a reel stand 16 via gears 28 and 16a. Thus, the capstan wheel 8 and the idler 24 are not overlapped, allowing to make the device thin and small in size.</p> |
