Abstract

PURPOSE: To manage with small brake spring force by reducing an angle contained between a straight line making a connection between the center of a reel turntable and the working point of a brake pad and that connecting the support point of a brake arm.
CONSTITUTION: When the power feeding to electromagnetic plunger 33 is cut off while reel turntables 10 and 20 rotate in directions A and (a), reset spring member 31 turns release lever 29 clockwise to part stop parts 29a and 29b from receiving parts 11b and 11a and brake arms 11 and 21 are rotated toward reel turntable 10 and 20 sides by spring member 23 to make each brake pad 26 press against the external circumference surfaces of reel turntables 10 and 20 for braking. Then, since angle F is small, self-locking action is made so as to increase brake force suddenly. This action further turns counterclockwise arm 11, which is stopped by stop piece 28 by coming in contact. Additionally, auxiliary arm 24 is turned counterclockwise by pressing pad 26 against the external circumference surface of a reel turntable and the depressing force of spring member 27 operates to keep the brake force constant. Therefore, each spring may be weak.
