<p>PURPOSE:To displace a displacement member in extremely short time according to rotation of a driving source by constituting a driving device in such a way that a worm gear connected to the shaft of the driving source and a slider designed to be made contactable with the displacement member are slided by the rotation of the shaft of the driving source in a specified direction. CONSTITUTION:A driving device 27 is provided with the worm 5 which is connected to the shaft of a motor 3 when a lever 2 is displaced by utilizing the rotation of the motor 3 as well as the slider 28 and a spring 29. A projection 31 which fits slidably into the recess of a worm accepting member 30 is formed to one end face of the worm 5. The slider 28 is slidably supported in the axial direction of the worm 5 by a guiding member 32 fixed to a cam shaft 13. The slider 28 is so energized by the spring 29 as to slide rightward and the bent part 35 of the slider 28 is pressed to the worm 5. The rotation of the worm 5 is transmitted to a cam plate 11, by which the pin 20 of the lever 2 engaged with the notch 21 of the cam plate 11 is disengaged therefrom. The cam plate 13 is then moved leftward by a spring 22, by which a brake member 23 is brought into press contact with a reel turntable 4. The reel turntable is thus braked in extremely short time.</p> |
