<p>PURPOSE:To improve the transmission efficiency of a whole driving system through simple constitution by engaging a tooth part at the tip end of an arm with the gear part of a pulley when rotation is transmitted from the pulley to a reel stand, and holding the arm at an intermediate position where it is not in contact with both the reel stands when the rotation is not transmitted. CONSTITUTION:The gear part 3a is provided at the outer circumference of the pulley 3, and the tooth part 5a capable of engaging with the gear part 3a of the pulley 3 is provided at the tip end of the arm 5, and the tooth part 5a of the arm 5 is engaged with the gear part 3a of the pulley 3. Then, such positional relation that the arm 5 and an idler 6 are moved toward a direction corresponding to the revolving direction of the pulley 3, and simultaneously, when the idler 6 is positioned at a position where it is in contact with the pulley 3 and either a feeding reel stand 1 or a winding reel stand 2, the engagement of the gear part 3a and the tooth part 5a is disengaged is given. Thus, the driving system of the high transmission efficiency can be obtained through the simple constitution.</p> |
