<p>PURPOSE:To reduce the power consumption, to make a device small-sized, and also to suppress a mechanical noise, by using a small-sized DC motor and one group of working levers. CONSTITUTION:A cylindrical rotary cam 26 is rotated through a pinion 28b and a gear 27 by a small-sized DC motor 13. When the rotary cam 26 rotates forward by forward turn of the motor 13, contact parts of working levers 34-39 do not contact by rise of a lever which is not shown in the figure, but jump a cam part 40 of the rotary cam 26, close an electric switch which is not shown in the figure, to which a working lever to be selected corresponds, and rotate the rotary cam in reverse immediately after the jump operation, therefore, the cam part 40 contacts, moves the working levers 34-39 by a prescribed stroke and locks them selectively. Also, to a rotary shaft 28a, a rotary cam 29 is fixed, and an idle end part 15c of a lever 15 contacts. When converting the mode, control members 15a, 15b contact with teeth of flat ratchet teeth 12, 12a, and control reel bases 11, 11a and reels 10, 10a.</p> |
